Description
本発明は、容器内の圧力により開閉するキャップ及び容器に関する。 The present invention relates to a cap and a container that open and close by pressure in the container.
従来、収容した内容物を吐出する容器として、チューブ容器や二重容器が知られている。チューブ容器として、例えば、弾性変形可能な容器本体と、容器本体の口部に装着され、逆止弁及び吐出ノズルを有するキャップと、を備える構成が知られている。 Conventionally, a tube container and a double container are known as a container for discharging the contained contents. As a tube container, for example, a configuration is known to include a container body that can be elastically deformed, and a cap that is attached to the mouth of the container body and has a check valve and a discharge nozzle.
二重容器として、例えば、可撓性に富んだ内容器及び当該内容器が内装された外容器を有する容器本体と、容器本体の口部に装着され、逆止弁及び吐出ノズルを有するキャップと、を備える容器が知られている。このような二重容器は、外容器に吸気弁を有し、外容器が押圧力により変形することで内容器が圧縮され、内容物を吐出ノズルから吐出する。 As a double container, for example, a container body having a highly flexible inner container and an outer container in which the inner container is built, and a cap attached to the mouth of the container body and having a check valve and a discharge nozzle. Containers with, are known. In such a double container, the outer container has an intake valve, and the outer container is deformed by the pressing force to compress the inner container, and the contents are discharged from the discharge nozzle.
また、二重容器は、内容物を吐出した後に外容器が復元することで、吸気弁から外容器と内容器との間に空気が供給される。これにより、二重容器は、内容器の復元を極力抑えて、内容器に空気が侵入することを防止する。また、二重容器は、キャップに設けられた蓋体が閉じられ、蓋体の内面に設けられた密封リングと吐出ノズルの開口が嵌合することで、内容器が密封される。 Further, in the double container, air is supplied from the intake valve between the outer container and the inner container by restoring the outer container after discharging the contents. As a result, the double container suppresses the restoration of the inner container as much as possible and prevents air from entering the inner container. Further, in the double container, the inner container is sealed by closing the lid provided on the cap and fitting the sealing ring provided on the inner surface of the lid with the opening of the discharge nozzle.
しかし、このような容器は、内容物を吐出した後に吐出ノズルの逆止弁が閉じると、吐出ノズル内に内容物が残存する。当該残存した内容物は、吐出ノズルの先端に残り、次に使用するときに吐出ノズルの先端からの液だれの原因となる虞があった。また、蓋体を閉じるときに、密封リングが吐出ノズルの吐出口と嵌合すると、吐出口に位置する残存した内容物が溢れ出し、キャップ内が汚れる虞があった。 However, in such a container, when the check valve of the discharge nozzle is closed after the contents are discharged, the contents remain in the discharge nozzle. The remaining contents remained at the tip of the discharge nozzle, and there was a risk of causing dripping from the tip of the discharge nozzle when used next time. Further, if the sealing ring is fitted with the discharge port of the discharge nozzle when the lid is closed, the remaining contents located at the discharge port may overflow and the inside of the cap may become dirty.
そこで、特開２０１６−３７２９０号公報に開示されるように、内容物を吐出した後に、吐出ノズル内に残存した内容物が漏出することを抑制する容器が知られている。この容器は、吐出ノズル内に逆止弁の弁体が当接する弁座部を設けるとともに、当該弁座部に内容物の流通を許容する流通溝を設ける構成とする。吐出通路内に残留する内容物は、当該流通溝から内容器内に戻る。これにより、容器は、吐出ノズル内に残留した内容物による液だれやキャップの汚れを抑制する。 Therefore, as disclosed in Japanese Patent Application Laid-Open No. 2016-37290, there is known a container that suppresses leakage of the remaining contents in the discharge nozzle after the contents are discharged. This container is configured to be provided with a valve seat portion in which the valve body of the check valve is in contact with the discharge nozzle, and a flow groove for allowing the flow of contents is provided in the valve seat portion. The contents remaining in the discharge passage return to the inner container from the distribution groove. As a result, the container suppresses dripping and dirt on the cap due to the contents remaining in the discharge nozzle.
しかしながら、上述した容器では、内容物の粘度が高い場合には、吐出通路内に残留する内容物が当該流通溝から内容器内に戻らない場合がある。戻らない場合には、吐出ノズルの開口から内容物の液だれが生じる虞がある。また、この容器は、蓋体を閉じるときに、密封リングが吐出ノズルの吐出口と嵌合すると、吐出口に残存した内容物が溢れ出し、キャップ内が汚れる虞がある。 However, in the above-mentioned container, when the viscosity of the contents is high, the contents remaining in the discharge passage may not return from the distribution groove into the inner container. If it does not return, there is a risk that the contents will drip from the opening of the discharge nozzle. Further, in this container, if the sealing ring is fitted with the discharge port of the discharge nozzle when the lid is closed, the contents remaining in the discharge port may overflow and the inside of the cap may become dirty.
また、内容器内と吐出ノズルとが流通溝を介して連通している。このため、内容物の粘度が低い場合には、吐出通路内に残留する内容物が当該流通溝から内容器内に吸引された後に内容器内に外気が浸入して、内容物の酸化を促進する虞がある。 Further, the inside of the inner container and the discharge nozzle communicate with each other through the distribution groove. Therefore, when the viscosity of the contents is low, the contents remaining in the discharge passage are sucked into the inner container from the distribution groove, and then the outside air infiltrates into the inner container to promote the oxidation of the contents. There is a risk of
そこで、本発明は、逆止弁の変形を利用して、ノズル内に残存する液をキャップ内に吸引することで液だれ及び汚れを抑制可能、且つ、容器本体内に外気が侵入することを抑制可能なキャップ及び容器を提供することを目的とする。 Therefore, the present invention makes it possible to suppress dripping and dirt by sucking the liquid remaining in the nozzle into the cap by utilizing the deformation of the check valve, and to prevent the outside air from entering the container body. It is an object of the present invention to provide caps and containers that can be suppressed.
本発明の一態様によれば、内容物を収容し、且つ、押圧力により変形する容器本体の口部に設けられるキャップは、内容物を吐出するノズル部と、流通孔が形成される底壁、並びに、前記底壁の中央部に設けられた弁座及びボスを含む、前記容器本体及び前記ノズル部間の流路上に設けられた弁室と、弁体及び前記弁体に設けられた前記弁座に当接する弁部を含み、前記弁室を上流側及び下流側に区分けする、前記弁室に設けられる逆止弁と、を備え、前記弁部が前記弁座に当接した状態から前記弁部が前記弁座から所定の距離離間する間、前記ボス及び前記弁部により前記内容物の流通が規制されることで、前記下流側の流路体積が減少し、さらに前記弁部が前記弁座から離間すると、前記弁部及び前記ボスの間に前記内容物を通過させる所定の流路を形成し、前記弁部が前記弁座から所定の距離離間し、前記内容物の流通が規制された状態から、前記弁部が前記弁座に当接するまでの間、前記下流側の流路体積が増加する。 According to one aspect of the present invention, the cap provided at the mouth of the container body that accommodates the contents and is deformed by pressing pressure has a nozzle portion for discharging the contents and a bottom wall on which a flow hole is formed. , And the valve chamber provided on the flow path between the container body and the nozzle portion, including the valve seat and the boss provided in the central portion of the bottom wall, and the valve body and the valve body provided in the valve body. A check valve provided in the valve chamber, which includes a valve portion that abuts on the valve seat and divides the valve chamber into an upstream side and a downstream side, is provided, and the valve portion is in contact with the valve seat. While the valve portion is separated from the valve seat by a predetermined distance, the flow of the contents is restricted by the boss and the valve portion, so that the flow path volume on the downstream side is reduced, and the valve portion is further formed. When separated from the valve seat, a predetermined flow path through which the contents pass is formed between the valve portion and the boss, the valve portion is separated from the valve seat by a predetermined distance, and the contents flow. The volume of the flow path on the downstream side increases from the regulated state until the valve portion abuts on the valve seat.
本発明の一態様によれば、吐出容器は、上述のキャップと、前記キャップが固定される前記口部を有する外容器、及び、前記外容器内に設けられ、前記外容器の変形に伴って変形する内容器を有する前記容器本体と、を備える。 According to one aspect of the present invention, the discharge container is provided in the above-mentioned cap, the outer container having the mouth portion to which the cap is fixed, and the outer container, and is provided in the outer container as the outer container is deformed. It includes the container body having a deformable inner container.
本発明によれば、逆止弁の変形を利用して、ノズル内に残存する液をキャップ内に吸引することで液だれ及び汚れを抑制可能、且つ、容器本体内に外気が侵入することを抑制可能なキャップ及び容器を提供することが可能となる。 According to the present invention, it is possible to suppress dripping and dirt by sucking the liquid remaining in the nozzle into the cap by utilizing the deformation of the check valve, and it is possible to prevent outside air from entering the container body.

図１乃至図４に示すように、容器１は、容器本体１０と、キャップ１１と、を備えている。容器１は、容器本体１０内に液状の内容物１００を収容する。容器１は、容器本体１０に押圧力を印加して変形させることで、内容物１００を適量吐出可能に構成されている。 As shown in FIGS. 1 to 4, the container 1 includes a container body 10 and a cap 11. The container 1 houses the liquid content 100 in the container body 10. The container 1 is configured so that an appropriate amount of the content 100 can be discharged by deforming the container body 10 by applying a pressing force.
ここで、内容物１００とは、例えば、醤油、オリーブ油やサラダ油等の食用油、ポン酢、ソース、だし汁、化粧水、シャンプー及びリンス等の液状物である。 Here, the content 100 is, for example, a liquid substance such as soy sauce, edible oil such as olive oil or salad oil, ponzu sauce, sauce, soup stock, lotion, shampoo and conditioner.
容器本体１０は、図１乃至図４に示すように、例えば、多層ブロー成形により形成される。容器本体１０は、外装と、その内面に剥離可能に積層された内装により構成される。容器本体１０は、所謂二重容器である。容器本体１０は、有底筒状の外容器２１と、外容器２１内に一体に設けられ、大部分が外容器２１に対して剥離可能な袋状の内容器２２と、を備えている。 As shown in FIGS. 1 to 4, the container body 10 is formed by, for example, multi-layer blow molding. The container body 10 is composed of an exterior and an interior that is detachably laminated on the inner surface thereof. The container body 10 is a so-called double container. The container body 10 includes a bottomed tubular outer container 21 and a bag-shaped inner container 22 that is integrally provided in the outer container 21 and is mostly peelable from the outer container 21.
外容器２１は、例えば、ポリエチレンやポリプロピレン等の樹脂材料により成形される。外容器２１は、有底筒状の胴部３１と、胴部３１と連続して一体に設けられた口部３２と、吸気弁３３と、を備える。 The outer container 21 is molded from a resin material such as polyethylene or polypropylene. The outer container 21 includes a bottomed tubular body portion 31, a mouth portion 32 continuously provided integrally with the body portion 31, and an intake valve 33.
胴部３１は、使用者の手指によって押圧されたときに、押圧力により弾性変形可能に構成される。口部３２は、第１突起部３２ａと、第２突起部３２ｃと、第３突起部３２ｂと、を有する。第１突起部３２ａは、外方に向かって環状に突出し、キャップ１１と係合す。第２突起部３２ｃは、内方に環状に突出してキャップ１１と密接する。第３突起部３２ｂは、内方に環状に突出する。第３突起部３２ｂは、キャッピング時に胴部３１の変形を防ぐための支え部となる。 The body portion 31 is configured to be elastically deformable by the pressing force when pressed by the user's fingers. The mouth portion 32 has a first protrusion 32a, a second protrusion 32c, and a third protrusion 32b. The first protrusion 32a projects outward in an annular shape and engages with the cap 11. The second protrusion 32c projects inward in an annular shape and comes into close contact with the cap 11. The third protrusion 32b projects inward in an annular shape. The third protrusion 32b serves as a support for preventing the body 31 from being deformed during capping.
吸気弁３３は、内容物１００を吐出するときに閉じる構造である。吸気弁３３は、胴部３１及び内容器２２間の圧力が大気圧よりも低い負圧となった場合に開くことで、胴部３１及び内容器２２の間の空間に外気を供給する。なお、吸気弁３３は、常時開とし、加圧されると閉じる構成であってもよい。 The intake valve 33 has a structure that closes when the content 100 is discharged. The intake valve 33 opens when the pressure between the body 31 and the inner container 22 becomes a negative pressure lower than the atmospheric pressure to supply outside air to the space between the body 31 and the inner container 22. The intake valve 33 may be configured to be constantly open and closed when pressurized.
内容器２２は、外容器２１に対して相溶性のない樹脂材料により構成される。内容器２２は、外容器２１よりも肉薄に構成され、高い可撓性を有する。内容器２２は、袋状に構成され、内容物１００を収容可能に構成される。例えば、内容器２２は、外容器２１の口部３２に一体に形成され、そして、外容器２１の胴部３１に対して剥離可能に形成される。 The inner container 22 is made of a resin material that is incompatible with the outer container 21. The inner container 22 is made thinner than the outer container 21 and has high flexibility. The inner container 22 is formed in a bag shape and is configured to be capable of accommodating the content 100. For example, the inner container 22 is integrally formed with the mouth portion 32 of the outer container 21 and is detachably formed with respect to the body portion 31 of the outer container 21.
図１乃至図７に示すように、キャップ１１は、キャップ本体４１と、キャップ本体４１にヒンジ４２を介して連結された蓋体４３と、が射出成形により一体に形成される。キャップ１１は、例えばポリプロピレンで構成される。 As shown in FIGS. 1 to 7, in the cap 11, the cap main body 41 and the lid body 43 connected to the cap main body 41 via a hinge 42 are integrally formed by injection molding. The cap 11 is made of, for example, polypropylene.
キャップ本体４１は、口部３２に固定され、基部５１及び吐出ノズル５２の一部によって構成される。キャップ本体４１は、逆止弁５３を収容可能、且つ、逆止弁５３によって上流側及び下流側に区画される弁室５４を有する。弁室５４は、容器本体１０内から吐出ノズル５２の後述するノズル部７２までの流路上に設けられる。 The cap body 41 is fixed to the mouth portion 32 and is composed of a base portion 51 and a part of the discharge nozzle 52. The cap body 41 has a valve chamber 54 that can accommodate the check valve 53 and is partitioned on the upstream side and the downstream side by the check valve 53. The valve chamber 54 is provided on the flow path from the inside of the container body 10 to the nozzle portion 72 described later of the discharge nozzle 52.
基部５１は、例えば、口部３２に固定され、ヒンジ４２及び蓋体４３と一体に成形される。基部５１は、筒状の外筒６１と、外筒６１の内径よりも外径が小径に構成された内筒（筒状部）６２と、外筒６１及び内筒６２の上部を連続する環状の壁部６３と、内筒６２の下部に設けられた円板状の底壁６４と、底壁６４の中央から上方に突出する環状の弁座部６５と、弁座部６５の中央に設けられ、上方に突出するボス６６と、を備えている。 The base 51 is fixed to the mouth 32, for example, and is integrally molded with the hinge 42 and the lid 43. The base 51 has a tubular outer cylinder 61, an inner cylinder (cylindrical portion) 62 having an outer diameter smaller than the inner diameter of the outer cylinder 61, and an annular shape in which the upper parts of the outer cylinder 61 and the inner cylinder 62 are continuous. 63, a disk-shaped bottom wall 64 provided at the bottom of the inner cylinder 62, an annular valve seat 65 protruding upward from the center of the bottom wall 64, and a central valve seat 65. It is equipped with a boss 66 that protrudes upward.
外筒６１は、開口する端部側の内周面に、口部３２の第１突起部３２ａと係合する環状の突起６１ａを有する。内筒６２の外径は、口部３２の対向する部位の最小内径よりも若干大径に形成される。また、内筒６２は、内周面に、断面が半円状の環状の凹部６２ａを有する。 The outer cylinder 61 has an annular protrusion 61a that engages with the first protrusion 32a of the mouth portion 32 on the inner peripheral surface on the end side to be opened. The outer diameter of the inner cylinder 62 is formed to be slightly larger than the minimum inner diameter of the opposite portion of the mouth portion 32. Further, the inner cylinder 62 has an annular recess 62a having a semicircular cross section on the inner peripheral surface.
壁部６３は、環状突起６３ａを有する。環状突起６３ａは、口部３２の端部の外径と略同一の内径を有し、口部３２が径方向外方へ変形することを抑制し、内筒６２の外周面と第２突起部３２ｃの内周面との接触力を強固にする。 The wall portion 63 has an annular protrusion 63a. The annular protrusion 63a has an inner diameter substantially the same as the outer diameter of the end portion of the mouth portion 32, suppresses the mouth portion 32 from being deformed outward in the radial direction, and the outer peripheral surface of the inner cylinder 62 and the second protrusion portion. The contact force with the inner peripheral surface of 32c is strengthened.
底壁６４は、単数の流通孔６４ａ又は複数の流通孔６４ａを有する。流通孔６４ａは、弁室５４に設けられる逆止弁５３と対向する位置の底壁６４に配置され、内容器２２及び弁室５４を流体的に連続する。 The bottom wall 64 has a single flow hole 64a or a plurality of flow holes 64a. The flow hole 64a is arranged on the bottom wall 64 at a position facing the check valve 53 provided in the valve chamber 54, and fluidly connects the inner container 22 and the valve chamber 54.
弁座部６５は、弁室５４内に配置される。弁座部６５は、底壁６４の吐出ノズル５２側の主面の中央部に設けられ、逆止弁５３の一部が密着する環状の座面（弁座）６５ａを含む。 The valve seat portion 65 is arranged in the valve chamber 54. The valve seat portion 65 is provided at the center of the main surface of the bottom wall 64 on the discharge nozzle 52 side, and includes an annular seat surface (valve seat) 65a to which a part of the check valve 53 is in close contact.
ボス６６は、弁室５４内に配置され、弁座部６５の中央部に設けられる。ボス６６は、例えば、円柱状に形成される。ボス６６は、逆止弁５３が所定量開いたときに、先端の外周面と逆止弁５３との間に所望の流量の内容物１００を通過可能な形状に形成される。ボス６６は、例えば、吐出ノズル５２側の端部の外周面に切欠部６６ａを有する。具体例として、切欠部６６ａは、ボス６６の外周面の４箇所に等間隔に配置される。 The boss 66 is arranged in the valve chamber 54 and is provided in the central portion of the valve seat portion 65. The boss 66 is formed in a columnar shape, for example. The boss 66 is formed in a shape that allows the content 100 of a desired flow rate to pass between the outer peripheral surface of the tip and the check valve 53 when the check valve 53 is opened by a predetermined amount. The boss 66 has, for example, a notch 66a on the outer peripheral surface of the end portion on the discharge nozzle 52 side. As a specific example, the notches 66a are arranged at four positions on the outer peripheral surface of the boss 66 at equal intervals.
吐出ノズル５２は、中心が開口する天壁部７１と、天壁部７１の中心上面に設けられた筒状のノズル部７２と、天壁部７１の他方の下面外周縁側に設けられた筒部７３と、天壁部７１の開口を覆う規制部７４と、を備えている。吐出ノズル５２は、例えば、ポリエチレンにより構成される。 The discharge nozzle 52 includes a top wall portion 71 having an open center, a tubular nozzle portion 72 provided on the central upper surface of the top wall portion 71, and a tubular portion provided on the outer peripheral edge side of the other lower surface of the top wall portion 71. A 73 and a regulating portion 74 that covers the opening of the top wall portion 71 are provided. The discharge nozzle 52 is made of, for example, polyethylene.
天壁部７１は、内筒６２の開口を覆うことで、内筒６２及び底壁６４との間に弁室５４を構成する。ノズル部７２は、キャップ１１の内容物１００を吐出する吐出口を構成する。 The top wall portion 71 covers the opening of the inner cylinder 62 to form a valve chamber 54 between the inner cylinder 62 and the bottom wall 64. The nozzle portion 72 constitutes a discharge port for discharging the content 100 of the cap 11.
筒部７３は、内筒６２に嵌合可能に形成される。また、筒部７３は、外周面に、内筒６２の凹部６２ａと係合可能な、断面が半円状の環状の凸部７３ａを有する。 The cylinder portion 73 is formed so as to be fitted to the inner cylinder 62. Further, the tubular portion 73 has an annular convex portion 73a having a semicircular cross section on the outer peripheral surface, which can be engaged with the concave portion 62a of the inner cylinder 62.
規制部７４は、ボス６６及び弁部８３の間の隙間とノズル部７２の開口との間に設けられる。規制部７４は、図２及び図７に矢印で示すように、ボス６６及び弁部８３の隙間からノズル部７２へ向かう内容物１００の流れを邪魔し、内容物１００の流れを規制し、ノズル部７２から吐出される内容物１００の吐出の勢いを和らげる。 The regulating portion 74 is provided between the gap between the boss 66 and the valve portion 83 and the opening of the nozzle portion 72. As shown by the arrows in FIGS. 2 and 7, the regulating unit 74 obstructs the flow of the content 100 from the gap between the boss 66 and the valve portion 83 toward the nozzle portion 72, regulates the flow of the content 100, and regulates the flow of the content 100. The momentum of the discharge of the content 100 discharged from the unit 72 is softened.
このような規制部７４は、ノズル部７２の弁室５４側の開口を覆う板状部材７４ａと、板状部材７４ａを天壁部７１又はノズル部７２に一体に接続するブリッジ７４ｂと、を含む。 Such a regulating portion 74 includes a plate-shaped member 74a that covers the opening of the nozzle portion 72 on the valve chamber 54 side, and a bridge 74b that integrally connects the plate-shaped member 74a to the top wall portion 71 or the nozzle portion 72. ..
板状部材７４ａは、ノズル部７２の弁室５４側の開口と略同形状の円板状に形成される。板状部材７４ａは、天壁部７１との間に、内容物１００の流路を構成する。板状部材７４ａは、内容物１００の流れ方向でノズル部７２の開口を覆うことで、内容物１００の流れ方向を変える邪魔板である。ブリッジ７４ｂは、板状部材７４ａの外周縁に等間隔に複数設けられる。ブリッジ７４ｂは、板状部材７４ａを天壁部７１に一体に連結する。 The plate-shaped member 74a is formed in a disk shape having substantially the same shape as the opening of the nozzle portion 72 on the valve chamber 54 side. The plate-shaped member 74a constitutes a flow path of the content 100 between the plate-shaped member 74a and the top wall portion 71. The plate-shaped member 74a is an obstacle plate that changes the flow direction of the content 100 by covering the opening of the nozzle portion 72 in the flow direction of the content 100. A plurality of bridges 74b are provided on the outer peripheral edge of the plate-shaped member 74a at equal intervals. The bridge 74b integrally connects the plate-shaped member 74a to the top wall portion 71.
図１乃至図７に示すように、逆止弁５３は、筒状のベース８１と、ベース８１の内周面に一体に設けられた環状の弁体８２と、弁体８２の内周縁に一体に設けられた弁部８３と、を備える。逆止弁５３は、内容物１００の圧力によって弾性変形可能、且つ、弾性変形後に復元可能な材料、例えば、ポリエチレンやエラストマー樹脂材料等により形成される。 As shown in FIGS. 1 to 7, the check valve 53 is integrated with the tubular base 81, the annular valve body 82 integrally provided on the inner peripheral surface of the base 81, and the inner peripheral edge of the valve body 82. The valve portion 83 provided in the above is provided. The check valve 53 is formed of a material that can be elastically deformed by the pressure of the content 100 and that can be restored after the elastic deformation, such as polyethylene or an elastomer resin material.
ベース８１は、例えば、底壁６４及び筒部７３によって挟持されることで、弁室５４に固定される。 The base 81 is fixed to the valve chamber 54 by being sandwiched by, for example, the bottom wall 64 and the tubular portion 73.
弁体８２は、中央が開口する環状に形成されるとともに、内周縁に弁部８３が一体に形成される。弁体８２は、弁部８３を座面６５ａに向かって付勢する。 The valve body 82 is formed in an annular shape with an opening in the center, and the valve portion 83 is integrally formed on the inner peripheral edge. The valve body 82 urges the valve portion 83 toward the seat surface 65a.
弁部８３は円環状に形成される。弁部８３の厚さは、弁体８２の厚さよりも厚く形成される。弁部８３の内径は、ボス６６の外径より若干大径に形成され、内容物１００が通過しない程度の隙間を有している。弁部８３は、例えば、断面が半円状に形成されることで、弁体８２よりも肉厚に形成される。弁部８３は、半円状の断面の曲面側の外面が座面６５ａに当接する。弁部８３は、弁体８２が変形して座面６５ａから離間したときに、ボス６６の外周面と、より具体例として、ボス６６の切欠部６６ａとの間に、内容物１００が所定の量だけ通過する通路を構成する隙間を形成する。 The valve portion 83 is formed in an annular shape. The thickness of the valve portion 83 is formed to be thicker than the thickness of the valve body 82. The inner diameter of the valve portion 83 is formed to be slightly larger than the outer diameter of the boss 66, and has a gap such that the content 100 does not pass through. The valve portion 83 is formed to be thicker than the valve body 82, for example, by being formed in a semicircular cross section. The outer surface of the valve portion 83 on the curved surface side of the semicircular cross section comes into contact with the seat surface 65a. In the valve portion 83, when the valve body 82 is deformed and separated from the seat surface 65a, the content 100 is predetermined between the outer peripheral surface of the boss 66 and, more specifically, the notch portion 66a of the boss 66. It forms a gap that constitutes a passage through which only the amount passes.
このような逆止弁５３は、弁部８３が座面６５ａと当接することで、弁室５４内を底壁６４側（上流側）とノズル部７２側（下流側）に区画するように密封する。 Such a check valve 53 is sealed so that the valve portion 83 comes into contact with the seat surface 65a to partition the inside of the valve chamber 54 into the bottom wall 64 side (upstream side) and the nozzle portion 72 side (downstream side). To do.
また、逆止弁５３は、弁部８３が座面６５ａから所定量離間することで、ボス６６の軸方向の中途部からボス６６の先端の外周面迄の間、より具体的にはボス６６の切欠部６６ａとの間に内容物１００を通過させる所定の流路を形成する。 Further, in the check valve 53, the valve portion 83 is separated from the seat surface 65a by a predetermined amount, so that the portion from the middle portion in the axial direction of the boss 66 to the outer peripheral surface of the tip of the boss 66, more specifically, the boss 66. A predetermined flow path through which the content 100 is passed is formed between the notch 66a and the notch 66a.
さらに言えば、逆止弁５３は、弁部８３が座面６５ａから離間した直後においては、所望の吐出量の内容物１００を通過可能な流路を極力形成しない。また、逆止弁５３は、ボス６６との間に流路を生じる部位である切欠部６６ａと対向したときに、ボス６６との間に内容物１００を所望の吐出量で通過可能な流路を形成する。なお、ボス６６の切欠部６６ａは、内容物１００に応じて適宜設定される。なお、内容物１００の粘性に合わせて、流通孔６４ａの開口面積、切欠部６６ａ等のボス６６の形状、ノズル部７２やノズル部７２及び規制部７４の板状部材７４ａとの間の開口面積を適宜設定することで、容器１の吐出量が設定される。 Further, the check valve 53 does not form a flow path through which the content 100 of a desired discharge amount can pass as much as possible immediately after the valve portion 83 is separated from the seat surface 65a. Further, when the check valve 53 faces the notch 66a, which is a portion that creates a flow path with the boss 66, the check valve 53 can pass the content 100 with the boss 66 at a desired discharge amount. To form. The notch 66a of the boss 66 is appropriately set according to the content 100. The opening area of the flow hole 64a, the shape of the boss 66 such as the notch 66a, and the opening area between the nozzle portion 72, the nozzle portion 72, and the plate-shaped member 74a of the regulating portion 74 according to the viscosity of the content 100. Is set as appropriate to set the discharge amount of the container 1.
このような逆止弁５３及び弁室５４は、弁部８３が弁座部６５の座面（弁座）６５ａに当接した状態から弁部８３が座面６５ａから所定の距離離間する間、内容物１００の流通が規制される。これにより、弁室５４の下流側の流路体積が減少し、さらに弁部８３が座面６５ａから離間すると、弁部８３及びボス６６の間に内容物１００を通過させる所定の流路を形成することが可能に構成される。また、逆止弁５３及び弁室５４は、弁部８３が座面６５ａから所定の距離離間し、内容物１００の流通が規制された状態から、弁部８３が座面６５ａに当接するまでの間、下流側の流路体積が増加することが可能に構成される。 In such a check valve 53 and the valve chamber 54, while the valve portion 83 is in contact with the seat surface (valve seat) 65a of the valve seat portion 65 and the valve portion 83 is separated from the seat surface 65a by a predetermined distance, The distribution of the content 100 is regulated. As a result, the volume of the flow path on the downstream side of the valve chamber 54 is reduced, and when the valve portion 83 is further separated from the seat surface 65a, a predetermined flow path through which the content 100 is passed is formed between the valve portion 83 and the boss 66. It is configured to be possible. Further, in the check valve 53 and the valve chamber 54, the valve portion 83 is separated from the seat surface 65a by a predetermined distance, and the flow of the content 100 is restricted until the valve portion 83 comes into contact with the seat surface 65a. During that time, the volume of the flow path on the downstream side can be increased.
蓋体４３は、係合部６３ｂと係合する凸状の被係合部４３ａと、ノズル部７２を閉塞する密封リング４３ｂと、を有する。 The lid 43 has a convex engaged portion 43a that engages with the engaging portion 63b, and a sealing ring 43b that closes the nozzle portion 72.
次に、このように構成された容器１の使用方法について説明する。
先ず、図１に示すように、内容物１００が充填された容器１は、例えば、容器本体１０が下方及びキャップ１１が上方の直立姿勢で保管される。使用時、即ち、内容物１００を吐出するときは、先ず、使用者は、容器１を把持し、蓋体４３を開けて、ノズル部７２を吐出先へ向ける。これにより、容器１は、ノズル部７２が下方となるように傾斜する。次いで、使用者は、内容物１００を吐出する間、外容器２１を押圧し、外容器２１に押圧力を印加する。
Next, a method of using the container 1 configured in this way will be described.
First, as shown in FIG. 1, the container 1 filled with the contents 100 is stored, for example, in an upright posture in which the container body 10 is downward and the cap 11 is upward. At the time of use, that is, when the content 100 is discharged, the user first grasps the container 1, opens the lid 43, and directs the nozzle portion 72 to the discharge destination. As a result, the container 1 is tilted so that the nozzle portion 72 is downward. Next, the user presses the outer container 21 while discharging the content 100, and applies a pressing force to the outer container 21.
外容器２１が押圧されることで外容器２１は弾性変形し、外容器２１の弾性変形に伴って、外容器２１によって内容器２２に直接押圧力が印加されるか、又は、外容器２１及び内容器２２の間の空間の空気が圧縮され、内容器２２に押圧力が印加される。これにより、内容器２２が弾性変形し、内容器２２内の圧力が増加すると、図２に示すように、弁体８２及び弁部８３が内容物１００に押圧される。これにより、弁部８３が座面６５ａから離間し、更に弁部８３がボス６６の先端まで移動する。なお、弁部８３及びボス６６は、センタリングされていることから、内容物１００の流れは偏らない。 When the outer container 21 is pressed, the outer container 21 is elastically deformed, and as the outer container 21 is elastically deformed, a pressing force is directly applied to the inner container 22 by the outer container 21, or the outer container 21 and The air in the space between the inner containers 22 is compressed, and a pressing force is applied to the inner container 22. As a result, when the inner container 22 is elastically deformed and the pressure inside the inner container 22 increases, the valve body 82 and the valve portion 83 are pressed against the content 100 as shown in FIG. As a result, the valve portion 83 is separated from the seat surface 65a, and the valve portion 83 further moves to the tip of the boss 66. Since the valve portion 83 and the boss 66 are centered, the flow of the content 100 is not biased.
そして、図２に矢印で示すように、内容器２２内の内容物１００は、流通孔６４ａから弁体８２及び底壁６４の間、弁部８３及び弁座部６５の間、弁部８３及びボス６６の切欠部６６ａの間を通って、弁室５４のノズル部７２側に移動する。そして、内容物１００は、規制部７４によってその流れ方向が、ボス６６の軸方向に対して交差する方向へ、換言すると、弁室５４の径方向外方への移動へと変わり、さらに、規制部７４の板状部材７４ａの外周面を周り、ノズル部７２へ移動し、ノズル部７２から吐出される。内容物１００がノズル部７２から吐出された内容物１００の体積だけ、内容器２２の容積が減少する。 Then, as shown by an arrow in FIG. 2, the content 100 in the inner container 22 is located between the flow hole 64a and the valve body 82 and the bottom wall 64, between the valve portion 83 and the valve seat portion 65, the valve portion 83 and the valve portion 83. It passes between the notches 66a of the boss 66 and moves to the nozzle portion 72 side of the valve chamber 54. Then, the content 100 is changed in the direction in which the flow direction intersects the axial direction of the boss 66 by the regulating unit 74, in other words, the valve chamber 54 is moved outward in the radial direction, and further regulated. It goes around the outer peripheral surface of the plate-shaped member 74a of the portion 74, moves to the nozzle portion 72, and is discharged from the nozzle portion 72. The volume of the inner container 22 is reduced by the volume of the content 100 ejected from the nozzle portion 72 of the content 100.
次いで、使用者は、所望の内容物１００を吐出させた後、外容器２１の押圧を解除する。外容器２１の押圧を解除することで、外容器２１の形状が復元し、外容器２１及び内容器２２の間に吸気弁３３から外気が吸入され、外容器２１及び内容器２２の間の空間が大気圧となる。このため、図３に示すように、弁体８２は、自身の復元力でもとの形状に復元し、ボス６６の外周面のうち、切欠部６６ａよりも座面６５ａ側に位置すると、弁室５４内が逆止弁５３によって区画され、ボス６６の外周面と弁部８３の内周縁との間の隙間が微小になり、実質的に、ボス６６及び弁部８３間が内容物で密封される。そして、さらに弁体８２が移動すると、図４に示すように、座面６５ａに弁部８３が当接し、座面６５ａ及び弁部８３間が密封される。 Next, the user releases the pressing of the outer container 21 after discharging the desired content 100. By releasing the pressure on the outer container 21, the shape of the outer container 21 is restored, the outside air is sucked from the intake valve 33 between the outer container 21 and the inner container 22, and the space between the outer container 21 and the inner container 22 is released. Becomes atmospheric pressure. Therefore, as shown in FIG. 3, when the valve body 82 is restored to its original shape by its own restoring force and is located on the seat surface 65a side of the notch 66a on the outer peripheral surface of the boss 66, the valve chamber The inside of 54 is partitioned by the check valve 53, the gap between the outer peripheral surface of the boss 66 and the inner peripheral edge of the valve portion 83 becomes minute, and the space between the boss 66 and the valve portion 83 is substantially sealed with the contents. To. Then, when the valve body 82 further moves, as shown in FIG. 4, the valve portion 83 comes into contact with the seat surface 65a, and the seat surface 65a and the valve portion 83 are sealed.
このとき、図３の位置から図４の位置まで、弁体８２及び弁部８３が移動することで、弁室５４の逆止弁５３よりも底壁６４側の内容物１００が内容器２２内に移動し、そして、弁室５４の逆止弁５３よりもノズル部７２側の容積が増加する。これにより、弁部８３が弁座部６５の座面（弁座）６５ａに当接するまで、ノズル部７２に位置する内容物１００が弁室５４に液引きされる。なお、逆止弁５３の８３の中央部に設けられた弁部８３の小径の開口及び底壁６４の中央部に設けられた小径のボス６６によりセンタリングを行うことで、密封及び流量規制の精度が向上する。 At this time, by moving the valve body 82 and the valve portion 83 from the position of FIG. 3 to the position of FIG. 4, the content 100 on the bottom wall 64 side of the check valve 53 of the valve chamber 54 is inside the inner container 22. And the volume on the nozzle portion 72 side of the check valve 53 of the valve chamber 54 increases. As a result, the content 100 located in the nozzle portion 72 is drained into the valve chamber 54 until the valve portion 83 comes into contact with the seat surface (valve seat) 65a of the valve seat portion 65. The accuracy of sealing and flow rate regulation is achieved by centering with a small-diameter opening of the valve portion 83 provided in the central portion of the check valve 53 and a small-diameter boss 66 provided in the central portion of the bottom wall 64. Is improved.
このように構成された容器１によれば、内容物１００の吐出後に外容器２１が復元することに伴って弁体８２が復元することで、弁室５４のノズル部７２側の容積が増加することから、ノズル部７２に残存する内容物１００は弁室５４のノズル部７２側の容積の増加分だけ、弁室５４に戻されて液面が下がる。 According to the container 1 configured in this way, the volume of the valve chamber 54 on the nozzle portion 72 side is increased by restoring the valve body 82 as the outer container 21 is restored after the content 100 is discharged. Therefore, the content 100 remaining in the nozzle portion 72 is returned to the valve chamber 54 by the amount of increase in the volume of the valve chamber 54 on the nozzle portion 72 side, and the liquid level is lowered.
ノズル部７２の先端から内容物１００の液面が容器本体１０側に向かってさがることで、ノズル部７２の先端に内容物１００が残存することを防止できることから、次回使用時に、ノズル部７２が下方に向かうように容器１を傾斜させても、ノズル部７２から内容物が垂れることを抑制できる。即ち、容器１は、使用時の液だれを防止できる。 Since the liquid level of the content 100 decreases from the tip of the nozzle portion 72 toward the container body 10 side, it is possible to prevent the content 100 from remaining at the tip of the nozzle portion 72. Therefore, the nozzle portion 72 will be used next time. Even if the container 1 is tilted downward, it is possible to prevent the contents from dripping from the nozzle portion 72. That is, the container 1 can prevent dripping during use.
また、ノズル部７２に内容物１００が残存することを防止できることから、密封リング４３ｂをノズル部７２に挿入した場合に、内容物１００がノズル部７２から溢れ出ることを抑制できる。結果、キャップ本体４１の天壁部７１やノズル部７２や、蓋体４３が内容物１００によって汚れることを抑制できる。 Further, since the content 100 can be prevented from remaining in the nozzle portion 72, it is possible to prevent the content 100 from overflowing from the nozzle portion 72 when the sealing ring 43b is inserted into the nozzle portion 72. As a result, it is possible to prevent the top wall portion 71, the nozzle portion 72, and the lid body 43 of the cap body 41 from being contaminated by the content 100.
また、キャップ１１は、ノズル部７２の弁室５４内の開口を覆うように規制部７４を設けることで、ボス６６及び弁部８３間の隙間を流れる内容物１００の流れ方向が規制される。結果として、ボス６６及び弁部８３間の隙間を通過した内容物１００がノズル部７２に到達するまでの距離が増加するとともに、内容物１００が通過する流路の流路抵抗が増加する。これにより、ボス６６及び弁部８３間の隙間から弁室５４内に流れた内容物１００がノズル部７２から吐出される勢いを和らげることが可能となり、内容物１００をノズル部７２から吐出するときに、勢いよく内容物１００が吐出することを抑制できる。このため、容器１の使用時に、内容物１００が飛散することを防止し、内容物１００を所望の位置にノズル部７２から吐出することができる。 Further, the cap 11 is provided with the regulating portion 74 so as to cover the opening in the valve chamber 54 of the nozzle portion 72, so that the flow direction of the content 100 flowing through the gap between the boss 66 and the valve portion 83 is regulated. As a result, the distance until the content 100 passing through the gap between the boss 66 and the valve portion 83 reaches the nozzle portion 72 increases, and the flow path resistance of the flow path through which the content 100 passes increases. As a result, it is possible to soften the momentum of the content 100 flowing into the valve chamber 54 from the gap between the boss 66 and the valve portion 83, and when the content 100 is discharged from the nozzle portion 72. In addition, it is possible to vigorously suppress the discharge of the content 100. Therefore, when the container 1 is used, the content 100 can be prevented from scattering, and the content 100 can be discharged from the nozzle portion 72 at a desired position.
また、キャップ１１は、ボス６６を有し、ボス６６及び弁部８３の間に内容物１００を通過する流路を設ける構成とした。このため、キャップ１１は、弁部８３の開口の芯出しが可能となるとともに、ボス６６及び弁部８３の間の隙間の管理が容易となる。加えて、ボス６６の先端側に、内容物１００の流量を調整するための切欠部６６ａを設けることで、内容物１００の吐出量の管理が容易となる。結果、キャップ１１は、製造によるばらつきを抑制して、歩留まりを向上させることが可能となる。 Further, the cap 11 has a boss 66, and a flow path through which the content 100 passes is provided between the boss 66 and the valve portion 83. Therefore, the cap 11 can center the opening of the valve portion 83, and can easily manage the gap between the boss 66 and the valve portion 83. In addition, by providing a notch 66a for adjusting the flow rate of the content 100 on the tip side of the boss 66, it becomes easy to manage the discharge amount of the content 100. As a result, the cap 11 can suppress variations due to manufacturing and improve the yield.
また、弁部８３は、断面形状を半円状とし、そして、座面６５ａ側に突出するように、座面６５ａと対向する面を曲面状とした。この構成により、逆止弁５３を基部５１に配置するときに、弁部８３にボス６６が挿入されるときにボス６６と当接する面が曲面となることから、当該曲面が弁部８３をボス６６の外周面に案内する機能を奏し、逆止弁５３の組立性が向上する。また、弁部８３を座面６５ａ側に突出する半円状の断面形状とすることで、弁部８３と座面６５ａとの接触する面積を極力小さくすること、換言すると、弁部８３を座面６５ａに対して環状に線接触させることが可能となる。よって、弁部８３は、弁体８２の復元力によって弁部８３を座面６５ａに全周に亘って密着させることが可能となる。 Further, the valve portion 83 has a semicircular cross-sectional shape and a curved surface facing the seat surface 65a so as to project toward the seat surface 65a. With this configuration, when the check valve 53 is arranged on the base 51, the surface that comes into contact with the boss 66 when the boss 66 is inserted into the valve portion 83 becomes a curved surface, so that the curved surface bosses the valve portion 83. It functions to guide the outer peripheral surface of 66, and the assemblability of the check valve 53 is improved. Further, by forming the valve portion 83 into a semicircular cross-sectional shape protruding toward the seat surface 65a, the area of contact between the valve portion 83 and the seat surface 65a can be minimized, in other words, the valve portion 83 can be seated. It is possible to make line contact with the surface 65a in an annular shape. Therefore, the valve portion 83 can be brought into close contact with the seat surface 65a over the entire circumference by the restoring force of the valve body 82.
また、容器１は、内容器２２が逆止弁５３によって気密に密封されることから、内容物１００の吐出時や保管時に、当該流通孔６４ａから内容器２２側に空気が侵入することを防止できる。 Further, since the inner container 22 of the container 1 is hermetically sealed by the check valve 53, it is possible to prevent air from entering the inner container 22 side from the distribution hole 64a when the content 100 is discharged or stored. it can.
上述したように本発明の第１の実施形態に係るキャップ１１を用いた容器１によれば、ノズル部７２内に残存する液をキャップ１１内に吸引することで使用時の液だれ及びキャップ１１の汚れを防止可能、且つ、容器本体１０内に外気が侵入することを防止可能となる。 As described above, according to the container 1 using the cap 11 according to the first embodiment of the present invention, the liquid remaining in the nozzle portion 72 is sucked into the cap 11 to cause dripping and the cap 11 during use. It is possible to prevent the dirt from entering the container body 10 and prevent outside air from entering the container body 10.
なお、本発明は、上記実施形態に限定されない。例えば、上述した例では、ボス６６の先端側の外周面に４つの切欠部６６ａを設けることで、ボス６６の外周面と弁部８３との間の流路を流れる内容物１００の吐出量を調整する例を説明したがこれに限定されない。例えば、図８に示すように、ボス６６は、切欠部６６ａを有さずに、先端側を円錐台形状とする構成としてもよい。また、ボス６６は、切欠部６６ａを設ける場合には、その数が限定されず、また、平面状の切欠部６６ａでなく、溝であってもよい。 The present invention is not limited to the above embodiment. For example, in the above-described example, by providing the four notches 66a on the outer peripheral surface on the tip end side of the boss 66, the discharge amount of the content 100 flowing through the flow path between the outer peripheral surface of the boss 66 and the valve portion 83 can be reduced. An example of adjustment has been described, but the present invention is not limited to this. For example, as shown in FIG. 8, the boss 66 may have a truncated cone shape on the tip end side without having a notch 66a. Further, when the notch 66a is provided, the number of the boss 66 is not limited, and the boss 66 may be a groove instead of the flat notch 66a.
また、上述した例では、基部５１の底壁６４に設けられた流通孔６４ａを逆止弁５３の弁体８２と対向する例を説明したが、図９に示すように、底壁６４に設けられる流通孔６４ａの位置は弁体８２と対向しない位置にもうけられていてもよい。 Further, in the above-described example, an example in which the flow hole 64a provided in the bottom wall 64 of the base 51 faces the valve body 82 of the check valve 53 has been described, but as shown in FIG. 9, it is provided in the bottom wall 64. The position of the flow hole 64a to be formed may be provided at a position not facing the valve body 82.
また、上述した例では、ノズル部７２は、ボス６６と軸方向で対向する位置に設けられる例を説明したがこれに限定されない。例えば、図１０に示すように、ノズル部７２は、ボス６６と軸方向に直交する方向、換言すると径方向にずれた位置に配置される構成であってもよい。このような構成とすることで、ボス６６の外周面と弁部８３との間の隙間を流れた内容物１００の流れは、天壁部７１にあたってノズル部７２に向かって径方向へその流れ方向が案内されることから、規制部７４の機能を天壁部７１が構成することになる。即ち、天壁部７１が規制部７４を構成することになることから、キャップ１１は、ノズル部７２をボス６６と径方向にずらすことで、規制部７４を設けることを要しないことから、キャップ１１の構成を簡素化することができる。 Further, in the above-described example, the example in which the nozzle portion 72 is provided at a position facing the boss 66 in the axial direction has been described, but the present invention is not limited to this. For example, as shown in FIG. 10, the nozzle portion 72 may be arranged at a position orthogonal to the boss 66 in the axial direction, in other words, at a position deviated from the radial direction. With such a configuration, the flow of the content 100 flowing through the gap between the outer peripheral surface of the boss 66 and the valve portion 83 hits the top wall portion 71 and is in the radial direction toward the nozzle portion 72. Is guided, so that the top wall portion 71 constitutes the function of the regulation portion 74. That is, since the top wall portion 71 constitutes the regulation portion 74, the cap 11 does not need to be provided with the regulation portion 74 by shifting the nozzle portion 72 in the radial direction from the boss 66. The configuration of 11 can be simplified.
また上述した例では、規制部７４は、弁室５４内のボス６６よりもノズル部７２側であって、且つ、ボス６６及び弁部８３の間に形成される隙間並びにノズル部７２の間に設けられる例として、吐出ノズル５２に設ける例を説明したがこれに限定されない。例えば、図１１に示すように、規制部７４は、ボス６６の先端に設ける構成としてもよい。このような構成とする場合には、例えば、ボス６６の先端を開口させて、板状部材７４ａをボス６６の先端に固定するために、ボス６６の先端の開口に嵌合するピン状の嵌合部７４ｃを設ける構成とすればよい。即ち、規制部７４は、ボス６６の外周面と弁部８３との間に生じる隙間とノズル部７２の開口との間に設けることで、弁室５４内を流れる内容物１００の流れ方向を変えることが可能であれば、適宜設定可能である。 Further, in the above-described example, the regulating portion 74 is on the nozzle portion 72 side of the boss 66 in the valve chamber 54, and is between the gap formed between the boss 66 and the valve portion 83 and the nozzle portion 72. As an example to be provided, an example of providing the discharge nozzle 52 has been described, but the present invention is not limited to this. For example, as shown in FIG. 11, the regulation unit 74 may be provided at the tip of the boss 66. In such a configuration, for example, a pin-shaped fitting that fits into the opening at the tip of the boss 66 in order to open the tip of the boss 66 and fix the plate-shaped member 74a to the tip of the boss 66. The configuration may be such that the joint portion 74c is provided. That is, the regulating portion 74 changes the flow direction of the content 100 flowing in the valve chamber 54 by being provided between the gap formed between the outer peripheral surface of the boss 66 and the valve portion 83 and the opening of the nozzle portion 72. If possible, it can be set as appropriate.
また、上述した例では、弁部８３は、座面６５ａへの接触面積を小さくさせるために、座面６５ａに向かって突出するように断面形状を半円状とする構成を説明したがこれに限定されない。例えば、図１２に示すように、弁部８３を弁体８２よりも肉厚の円環板状とし、座面６５ａの形状を平面状ではなく、弁部８３に向かって突出する円環の突起状、具体例として、座面６５ａの断面形状を半円状としてもよい。 Further, in the above-described example, in order to reduce the contact area with the seat surface 65a, the valve portion 83 has a semicircular cross-sectional shape so as to project toward the seat surface 65a. Not limited. For example, as shown in FIG. 12, the valve portion 83 has an annular plate shape that is thicker than the valve body 82, and the shape of the seat surface 65a is not a flat shape but a protrusion of an annulus that protrudes toward the valve portion 83. As a specific example, the cross-sectional shape of the seat surface 65a may be semicircular.
この他にも、キャップ１１は、例えば、図１３に示すように、座面６５ａを軸方向に対して傾斜する環状の傾斜面としてもよい。 In addition to this, the cap 11 may be, for example, an annular inclined surface in which the seat surface 65a is inclined with respect to the axial direction, as shown in FIG.
また、上述した例に変えて、図１３ボス６６の先端の稜部を曲面形状とし、そして、弁部８３の座面６５ａと当接するシール部を軸方向に対して傾斜する傾斜面とし、弁部８３が座面６５ａから離間したときに、ボス６６の稜部と弁部８３のシール部とに隙間を形成する構成としてもよい。 Further, instead of the above-mentioned example, the ridge portion at the tip of the boss 66 in FIG. 13 has a curved surface shape, and the seal portion in contact with the seat surface 65a of the valve portion 83 has an inclined surface inclined in the axial direction. When the portion 83 is separated from the seat surface 65a, a gap may be formed between the ridge portion of the boss 66 and the seal portion of the valve portion 83.
また、上述した例では、基部５１が口部３２に固定される例を説明したがこれに限定されない。例えば、図１３に示すように、吐出ノズル５２に筒状の外筒６１及び外筒６１の内径よりも外径が小径に構成された内筒６２を設け、基部５１を有底円筒状として、基部５１の筒状部を内筒６２に嵌合させる構成としてもよい。 Further, in the above-described example, an example in which the base portion 51 is fixed to the mouth portion 32 has been described, but the present invention is not limited to this. For example, as shown in FIG. 13, the discharge nozzle 52 is provided with a tubular outer cylinder 61 and an inner cylinder 62 having an outer diameter smaller than the inner diameter of the outer cylinder 61, and the base 51 is formed into a bottomed cylinder. The tubular portion of the base portion 51 may be fitted to the inner cylinder 62.
また、上述した例では、ノズル部７２は、円筒状に形成される例を説明したがこれに限定されない。例えば、図８乃至図１３に示すように、ノズル部７２は、液切れをよくするために、先端に向かって漸次拡径する形状としてもよく、さらに、先端が湾曲する形状としてもよい。また、ノズル部７２の長さも適宜設定可能である。 Further, in the above-mentioned example, the example in which the nozzle portion 72 is formed in a cylindrical shape has been described, but the present invention is not limited to this. For example, as shown in FIGS. 8 to 13, the nozzle portion 72 may have a shape in which the diameter of the nozzle portion 72 is gradually increased toward the tip in order to improve drainage, and the nozzle portion 72 may be in a shape in which the tip is curved. Further, the length of the nozzle portion 72 can be set as appropriate.
また、上述した例では、逆止弁５３は、筒状のベース８１の内周面の一部に、弁体８２が一体に形成される円環板状の連結部８１ａを設ける構成を説明したがこれに限定されない。例えば、図１３に示すように、逆止弁５３は、筒状のベース８１の内周面の一部に、直接弁体８２が一体に形成される構成としてもよい。また、弁体８２の形状は断面が円弧状に構成されていてもよく、複数の曲率半径を有する波形状に構成されていてもよく、また、断面が直線状に形成される円環板状に構成されていてもよい。 Further, in the above-described example, the check valve 53 has a configuration in which a ring plate-shaped connecting portion 81a in which the valve body 82 is integrally formed is provided on a part of the inner peripheral surface of the tubular base 81. Is not limited to this. For example, as shown in FIG. 13, the check valve 53 may have a configuration in which the valve body 82 is integrally formed on a part of the inner peripheral surface of the tubular base 81. Further, the shape of the valve body 82 may be formed into an arc shape in a cross section, a wave shape having a plurality of radii of curvature, or a ring plate shape in which the cross section is formed in a straight line. It may be configured in.
さらに、上述した例では、キャップ１１は、ヒンジ４２を介してキャップ本体４１及び蓋体４３が連結される構成を説明したがこれに限定されない。例えば、キャップ本体４１及び蓋体４３は別体に構成され、キャップ本体４１に雄螺子を設け、蓋体４３に雌ねじを設けることで、キャップ本体４１に蓋体４３を着脱できる構成としてもよい。 Further, in the above-described example, the cap 11 is not limited to the configuration in which the cap body 41 and the lid 43 are connected via the hinge 42. For example, the cap body 41 and the lid 43 may be formed separately, and the cap body 41 may be provided with a male screw and the lid 43 may be provided with a female screw so that the lid 43 can be attached to and detached from the cap body 41.
また、上述した例では、容器本体１０は二重容器である構成を説明したがこれに限定されず、弾性変形可能なチューブ容器を容器本体１０に用いる構成としてもよい。 Further, in the above-described example, the configuration in which the container body 10 is a double container has been described, but the present invention is not limited to this, and an elastically deformable tube container may be used for the container body 10.
また、弁部８３は、上述した断面形状に限定されない。即ち、弁部８３は、座面６５ａと当接してボス６６との間の流路を密封可能、且つ、座面６５ａから離間してボス６６の例えば切欠部６６ａの間に所望の流量の内容物を通過可能であれば、適宜設定できる。 Further, the valve portion 83 is not limited to the cross-sectional shape described above. That is, the valve portion 83 can abut the seat surface 65a to seal the flow path between the boss 66 and the valve portion 83, and the content of the desired flow rate is separated from the seat surface 65a and between the boss 66, for example, the notch 66a. If it can pass through objects, it can be set as appropriate.
さらに、上述した例では、ボス６６及び弁部８３の間に所望の流量の内容物１００を通過可能とするために、吐出ノズル５２側の端部の外周面に切欠部６６ａを有する構成を説明したがこれに限定されない。例えば、図１４に示すように、ボス６６を円柱状とし、ボス６６の先端を座面６５ａ、即ちボス６６の先端面を座面６５ａとし、弁部８３をボス６６先端の座面６５ａに当接することで、ボス６６及び弁部８３間を密封する構成としてもよい。このような構成とした場合には、図１４に二点鎖線で示すように、内容物１００によって弁体８２が変形し、弁部８３が座面６５ａから離間することで、ボス６６及び弁部８３の間に所定の流路が生じる。また、このような構成の弁部８３は、座面６５ａと当接する部位の中央に開口８３ａを有する。この開口８３ａの内径は、ボス６６の外径よりも小径に形成される。また、開口８３ａは、内容物１００の流量を規制し、所定の流量とする規制孔である。このため、開口８３ａの内径は、内容物１００が所望の流量となる内径に設定される。 Further, in the above-described example, a configuration having a notch 66a on the outer peripheral surface of the end portion on the discharge nozzle 52 side will be described so that the content 100 having a desired flow rate can pass between the boss 66 and the valve portion 83. However, it is not limited to this. For example, as shown in FIG. 14, the boss 66 has a columnar shape, the tip of the boss 66 has a seat surface 65a, that is, the tip surface of the boss 66 has a seat surface 65a, and the valve portion 83 hits the seat surface 65a at the tip of the boss 66. The boss 66 and the valve portion 83 may be sealed by being in contact with each other. In such a configuration, as shown by the alternate long and short dash line in FIG. 14, the valve body 82 is deformed by the content 100, and the valve portion 83 is separated from the seat surface 65a, so that the boss 66 and the valve portion are separated. A predetermined flow path is generated between 83. Further, the valve portion 83 having such a configuration has an opening 83a in the center of the portion that comes into contact with the seat surface 65a. The inner diameter of the opening 83a is formed to be smaller than the outer diameter of the boss 66. Further, the opening 83a is a regulation hole that regulates the flow rate of the content 100 to a predetermined flow rate. Therefore, the inner diameter of the opening 83a is set to the inner diameter at which the content 100 has a desired flow rate.
また、上述した例では、容器本体１０は二重容器である構成を説明したがこれに限定されず、弾性変形可能なチューブ容器を容器本体１０に用いる構成としてもよい。 Further, in the above-described example, the configuration in which the container body 10 is a double container has been described, but the present invention is not limited to this, and an elastically deformable tube container may be used for the container body 10.
