Definitions
- This invention relates to a pillow packaging bag containing contents filled with a liquid or fluid.
- Pillow wrapping bags are pillow-shaped bags that are cut by heat-sealing (horizontal sealing) in a transverse direction at regular intervals after a single film is heat-sealed back-to-back (back-seal) to form a cylinder.
- Pillow packaging bags are also called gassho-pasted bags and back-pasted bags, and are often used for automatic food packaging.
- jar-sized konjac jelly is sealed in a bag instead of a cup.
- Such a jelly food in a bag is easy to hold and can easily extrude the jelly from the opened bag.
- the jelly In a bag of jelly food, the jelly is easily pushed out of the bag. For this reason, consumers often put the jelly directly into their mouths by adding an opening that is a part of the horizontal seal to the mouth. However, if the opening is not cut cleanly, it will feel uncomfortable when the opening touches the lips. In particular, in the jelly food using the pillow packaging bag, the back seal is disposed near the opening, so that the back seal pierces the lips and feels uncomfortable.
- FIG. 6 is a view showing a conventional jelly food 51.
- FIG. 7 is a view showing a state in which the jelly-containing jelly 55 is pushed out in the conventional jelly food 51.
- the opening 68 is caught by the back seal 71.
- the opening 68 is caught on the back seal 71, there are frequent problems that the opening 68 becomes unnecessarily large, or conversely, the opening 68 does not open sufficiently.
- the opening 68 does not travel along the horizontal direction very often.
- the packaging bag 60 is largely cut, and the opening 68 becomes larger than necessary.
- the konjac-containing jelly 55 spills out or jumps out.
- FIG. 6 (b) when the opening 68 advances toward the upper end, the packaging bag 60 is shredded and the opening 68 becomes small and does not open sufficiently. For this reason, as shown in FIG. 7B, even if the packaging bag 60 is pushed, the konjac-containing jelly 55 is not pushed out well.
- the opening 68 can be formed in a straight line along the lateral direction, the problem that the konjac-containing jelly 55 pops out frequently occurs when the back seal 71 is torn laterally. This is because the consumer applies a strong force to tear the back seal 71 and tears the packaging bag 60 excessively. For this reason, the jelly 55 containing konjac vigorously jumps out of the opening 68.
- the present invention has been made in view of such problems, and an object of the present invention is to propose a pillow packaging bag containing contents that is less likely to cause discomfort to the consumer when the opening is placed in the mouth.
- An object of the present invention is to propose a pillow packaging bag containing contents that are appropriately formed when the side seal is cut to form the opening and the opening is not caught by the back seal.
- the pillow packaging bag with contents is a packaging bag with contents filled and sealed in a pillow packaging bag, and the horizontal seal disposed at the upper end of the pillow packaging bag has a stepped shape.
- a back seal disposed on the back surface of the pillow packaging bag is connected only to the retracted portion, and the projecting portion is cut off in a lateral direction to push out the fluid. It is characterized by that.
- the pillow package bag with contents according to the second embodiment of the present invention is characterized in that, in the first embodiment, the back seal is folded over the receding portion.
- the pillow package bag with contents according to the third embodiment of the present invention is characterized in that, in the first or third embodiment, a cutting notch is provided at an inner edge portion connecting the protruding portion and the retracted portion.
- the pillow package bag with contents according to the fourth embodiment of the present invention is characterized in that, in any of the first to third embodiments, the retracted portion is inclined in a direction away from the protruding portion.
- the pillow packaging bag with contents according to the fifth embodiment of the present invention is characterized in that, in any of the first to fourth embodiments, a corner prevention portion is provided at a corner of the pillow packaging bag.

- the jelly food in a bag (packaging bag with contents) 1 includes a packaging bag 10 made of a resin film and a konjac-containing jelly 5 filled and enclosed in the packaging bag 10.
- the konjac-containing jelly (fluid, gel-like confectionery) 5 is made by solidifying a jelly solution containing a gelling agent or the like by the action of the gelling agent in the same manner as a normal jelly.
- the jelly containing konjac 5 is characterized in that the jelly solution contains konjac fine powder.
- the konjac-containing jelly 5 may further contain any material as long as it contains at least a gelling agent and konjac fine powder.
- the jelly containing konjac 5 has a unique texture with high elasticity by containing konjac fine powder.
- the packaging bag (pillow packaging bag) 10 is a so-called pillow packaging bag, and is a bag body in which heat seals are formed at both ends in the longitudinal direction and the center of the back surface. That is, the packaging bag 10 is formed by heat-welding both ends of a single film into a cylindrical shape, and further heat-welding the upper and lower ends of the cylindrical film.
- the packaging bag 10 includes a housing portion 12, a back seal 21, and lateral seals 22 and 27.
- the accommodating portion 12 is a non-sealed portion that is not thermally welded out of a single film, and is a portion where the konjac-containing jelly 5 is filled and enclosed.
- the back seal 21 is formed over substantially the entire length in the center of the back surface of the packaging bag 10.
- the back seal 21 is also called a vertical seal or a center seal.
- the lateral seal 22 is formed over the entire region in the lateral direction at the upper end.
- the lateral seal 27 is formed over the entire region in the lateral direction at the lower end.
- the back seal 21 is formed almost at the center of the packaging bag 10. When viewed from the back, the back seal 21 is folded to the right. The upper and lower ends of the back seal 21 are overlapped with the horizontal seals 22 and 27. The upper end of the back seal 21 is folded over the receding portion 24 of the lateral seal 22. That is, the back seal 21 is connected only to the retracted portion 24.
- the horizontal seal 22 is formed in a stepped shape such that one (right side as viewed from the front) protrudes in the vertical direction and the other (left side as viewed from the front) retreats in the vertical direction.
- the horizontal seal 22 is formed in the shape of a so-called crank road (a saddle road). That is, the horizontal seal 22 has a shape in which two roads that bend at right angles are alternately connected.
- the protruding portion 23 is disposed on the right side of the horizontal seal 22, the retracted portion 24 is disposed on the left side, and the connecting portion (inner edge) 25 is disposed on the right side of the center.
- the protrusion part 23 and the retreat part 24 are along a horizontal direction.
- connection part 25 connects the left end of the protrusion part 23 and the right end of the retreat part 24 along the vertical direction.
- the connecting portion 25 is an inner edge of the packaging bag 10.
- the protruding portion 23, the retreating portion 24, and the connecting portion 25 are formed with substantially the same width dimension (seal width).
- the upper portion of the accommodating portion 12 is also formed in a stepped shape. That is, the upper portion of the accommodating portion 12 has a shape along the horizontal seal 22.
- the accommodating portion 12 includes a main accommodating portion 13 located below the retreating portion 24 and a narrow accommodating portion 14 located below the protruding portion 23 and communicating with the main accommodating portion 13. Since the connecting portion 25 is disposed on the right side of the center of the packaging bag 10, the lateral length of the narrow housing portion 14 is about 1/3 of the width of the packaging bag 10.
- the connecting portion 25 is provided with a notch 26 for cutting for opening the packaging bag 10.
- the cutting notch 26 is a V-shaped cut formed in the connecting portion 25 and is provided to assist the tearing of the packaging bag 10. That is, the notch 26 for cutting is provided in order to form the opening 18 which crosses the narrow accommodation part 14 from the connection part 25 and reaches the side edge of the packaging bag 10.
- the opening 18 is formed in the upper part of the packaging bag 10 by tearing the packaging bag 10 using the notch 26 for cutting. Thereby, the protrusion part 23 becomes a pull tab cut out from the packaging bag 10.
- a storage buffer 16 is provided at the corner of the storage 12.
- the accommodation buffer part (corner, corner prevention part) 16 is a part in which the left corner of the horizontal seal 22 (retreat part 24) and both corners of the horizontal seal 27 are recessed in the vertical direction to expand the accommodation part 12.
- cornering can be prevented. Thereby, when a plurality of bag-like jelly foods 1 are packed in a bag or a box, it is possible to prevent the cornering of the packaging bag 10 from being stuck in another adjacent packaging bag 10 and generating a pinhole.
- the reason why cornering can be prevented by the accommodation buffer 16 is as follows.
- a heated heat seal bar horizontal seal bar
- sticker of a pillow packaging bag is formed when the predetermined site
- the heated front side of the horizontal seal is more easily contracted than the back side when cooled. Therefore, in the conventional pillow packaging bag, a phenomenon occurs in which the horizontal seal collapses to the front side with the boundary line between the horizontal seal and the accommodating portion as an axis.
- sticker with a fixed seal width a corner standing part tends to become an acute angle more.
- the accommodating buffer 16 forms a step between the central portion of the accommodating portion 12 and both end portions at the boundary line between the lateral seals 22 and 27 and the accommodating portion 12, and the accommodating portion 12 has the lateral seals 22 and 27. It is important that it is provided so as to cut into. As a result, the seal width of the lateral seals 22 and 27 is wide at the center and narrow at both side ends.
- the dimensions, number, etc. of the storage buffer 16 are appropriately selected according to characteristics such as the elongation and tensile strength of the film, the size of the packaging bag 10 and the filling amount of the contents.
- the jelly food 1 in a bag is manufactured as follows, for example. First, a konjac-containing jelly solution containing a gelling agent and konjac powder is prepared in the same manner as in the case of making a normal konjac-containing jelly. In addition to the gelling agent and konjac powder, sugars, fruit juices, fragrances, acidulants, coloring agents, and the like can be added to the konjac-containing jelly solution as necessary.
- the prepared konjac-containing jelly solution is sterilized by heating.
- the heat sterilization can be performed by any method, for example, using a tube-type heat sterilizer.
- the sterilization conditions can be, for example, 120 to 140 ° C. and about 3 minutes.
- the konjac-containing jelly solution that has been sterilized is cooled to about 60 to 70 ° C. by a cooling device and filled and packaged using an appropriate filling and packaging machine.
- the filled packaging is preferably an aseptic filled packaging in which packaging is performed in a sterile environment using the sterilized contents and the sterilized packaging material.
- the packaged konjac-containing jelly solution After filling and packaging, the packaged konjac-containing jelly solution is cooled to 25 ° C. or lower and solidified. Thereby, the jelly food 1 in a bag in which the konjac-containing jelly 5 is filled and enclosed in the packaging bag 10 is obtained. In this jelly-packed jelly food 1, the konjac-containing jelly 5 is solidified in the packaging bag 10, so that the konjac-containing jelly 5 exists as one lump having a shape substantially equal to the shape of the housing portion 12.
- FIG. 3 is a view showing a state in which the protruding portion 23 is cut out and the konjac-containing jelly 5 is pushed out.
- the konjac jelly 5 enclosed in the packaging bag 10 can be eaten as follows. First, the consumer tears the upper portion of the packaging bag 10 in the lateral direction by using the cutting notch 26. Thereby, the packaging bag 10 is opened by the narrow accommodating part 14, and the opening 18 covering the whole horizontal direction of the narrow accommodating part 14 is formed.
- the consumer crushes the lower part of the packaging bag 10.
- a force from the lower part of the packaging bag 10 toward the upper part acts on the konjac-containing jelly 5 enclosed in the packaging bag 10, and the konjac-containing jelly 5 is pushed out from the opening 18. .
- the retreating part 24 functions as a movement suppressing structure that suppresses the movement of the konjac-containing jelly 5 to the upper part when the lower part of the packaging bag 10 is crushed.
- the konjac-containing jelly 5 exists as one lump, and the konjac-containing jelly 5 has a unique elasticity derived from konjac. For this reason, a part of the konjac-containing jelly 5 is compressed toward the narrow accommodating part 14 and the remaining part is pushed out from the opening 18 while being torn at the boundary between the narrow accommodating part 14 and the retreating part 24.
- the konjac-containing jelly 5 remains as one lump in the main housing portion 13, and thus a part thereof is pushed out from the opening 18 without being separated from the packaging bag 10.
- the retreat unit 24 blocks the movement of the konjac-containing jelly 5 toward the upper part, but does not restrict the movement in other directions. For this reason, when the konjac-containing jelly 5 in the packaging bag 10 is remaining, the konjac-containing jelly 5 in the vicinity of the retreating portion 24 can move toward the narrow accommodating portion 14 (opening opening 18). Eventually, all the konjac-containing jelly 5 can be pushed out from the accommodating part 12.
- the konjac-containing jelly 5 extruded from the packaging bag 10 can be reliably prevented from jumping into the mouth as it is and clogging the throat. Moreover, since it is necessary to bite the konjac-containing jelly 5 extruded from the packaging bag 10, it is possible to enjoy the unique texture of konjac-containing jelly.
- the upper part of the packaging bag 10 is often added to the mouth. That is, the consumer sandwiches the narrow container 14 (opening opening 18) with lips. At this time, since the opening 18 hits the lips of the consumer, if the opening 18 becomes jagged or the corners of the back seal 21 touch the lips, it will feel uncomfortable.
- the back seal 21 is folded over the receding portion 24 of the lateral seal 22, the back seal 21 is not included in the opening 18. That is, since the cutting notch 26 is formed only in the connecting portion 25 and only the connecting portion 25 is cut, the opening 18 does not become jagged. Therefore, the bagged jelly food 1 can prevent the consumer from feeling uncomfortable.
- the opening 18 does not reach the back seal 21 when the opening 18 is formed (the protruding portion 23 is cut) ( Not caught). For this reason, the opening 18 is appropriately formed. In other words, it can be avoided that the opening 18 becomes unnecessarily large, or conversely, the opening 18 does not open sufficiently. Therefore, the problem that the konjac-containing jelly 5 spills or jumps out from the opening 18 or the konjac-containing jelly 5 is not pushed out even when the packaging bag 10 is pressed does not occur.
- the back seal 21 is connected only to the retracted portion 24 of the lateral seal 22. For this reason, a beautiful opening 18 is easily formed in the protruding portion 23 of the horizontal seal 22. Therefore, when the opening 18 of the packaging bag 10 is added to the mouth, it is difficult for the consumer to feel uncomfortable. Further, since the opening 18 is not caught by the back seal 21, the opening 18 is appropriately formed. Therefore, an appropriate amount of konjac-containing jelly 5 is pushed out from the opening 18.
- Drawing 4 is a figure showing jelly food 2 with a bag concerning a second embodiment of the present invention, (a) a front view and (b) a back view.
- hatched parts indicate parts that have been heat-sealed (heat-welded).
- FIG. 5 is a view showing the jelly food 2 in a bag, where (a) a plan view, (b) a bottom view, and (c) a left side view.
- the bag-like jelly food 2 (packaging bag with contents) 2 is different from the bag-like jelly food 1 in the shape of the receding portion 34.
- the protruding portion 23 is disposed on the right side of the horizontal seal 22, the retracted portion 34 is disposed on the left side, and the connecting portion (inner edge) 25 is disposed on the right side of the center.
- the protrusion 23 is along the horizontal direction.
- the receding part 34 extends obliquely downward.
- the receding portion 34 is inclined downward at a moderate angle with respect to the lateral direction. More specifically, the right side of the center of the receding portion 34 is inclined at an angle of about 40 ° with respect to the lateral direction.
- the left side from the center of the receding portion 34 is inclined at an angle of about 15 ° with respect to the lateral direction.
- the connection part 25 connects the left end of the protrusion part 23 and the right end of the retreat part 34 along the vertical direction.
- the protruding part 23, the retreating part 34 and the connecting part 25 are formed to have substantially the same width dimension (seal width).
- the back seal 21 is connected only to the retracted portion 24 of the lateral seal 22, as in the bag-like jelly food 1. For this reason, a beautiful opening 18 is easily formed in the protruding portion 23 of the horizontal seal 22. Therefore, when the opening 18 of the packaging bag 10 is added to the mouth, it is difficult for the consumer to feel uncomfortable. Further, since the opening 18 is not caught by the back seal 21, the opening 18 is appropriately formed. Therefore, an appropriate amount of konjac-containing jelly 5 is pushed out from the opening 18.
- the jelly food 2 in a bag has the receding portion 34 inclined obliquely downward.
- the retreat part 34 inclines in two steps. In other words, the right side of the center is greatly retracted obliquely downward, and the left side of the center is slowly retracted. For this reason, the vertical distance between the protruding portion 23 and the retracted portion 34 is increased. This makes it easier to grip the protruding portion 23 and the retracted portion 34 when the protruding portion 23 is cut to form the opening 18. Therefore, when the protrusion 23 is cut, the consumer can easily adjust the force, and the opening 18 can be appropriately formed.
- the packaging bag 10 is substantially square is shown, but the length of the packaging bag 10 is arbitrary.
- the packaging bag 10 may be vertically long (the length in the vertical direction is longer than the length in the horizontal direction).
- the jelly food 1 in a bag is not limited to the case where the contents are jelly 5 containing konjac. It may be agar or gelatin. Moreover, not only solid but drinking water (liquid) may be sufficient. Further, the content is not limited to food, but may be a medicine or the like. That is, the content may be anything (fluid) that is pushed out from the opening 18 when the lower portion of the packaging bag 10 is crushed. Fluids also include semi-solids such as margarine, shortening and chocolate. Filling packaging is not limited to aseptic filling packaging.
- the cutting notch 26 is not limited to a V-shaped cut. What is necessary is just a structure in which the opening 18 is formed in the upper part of the packaging bag 10 by tearing the packaging bag 10 (cutting out the protrusion part 23). For example, easy opening processing such as perforation may be used. Further, the size of the cutting notch 26, the cutting depth, and the like can be arbitrarily set.
- the packaging bag 10 may use a packaging film that is excellent in cross-cutting properties (straight-ahead cutting properties). That is, a film that is easy to cut the packaging bag 10 in the horizontal direction and difficult to cut in the vertical direction is used. Thereby, the opening 18 is satisfactorily formed along the lateral direction. It is possible to prevent the opening 18 from becoming unnecessarily large, or conversely, the opening 18 from being sufficiently opened.
- packaging films having excellent cross-cutting properties include Toray Industries, Inc. “YT42 Trefan”, Denka Corporation “Kalariyan Y”, and the like.
- the accommodation buffer part 16 may be provided at the right corner of the horizontal seal 22 (projecting part 23). The case where the accommodation buffer part 16 is not provided in the accommodation part 12 may be sufficient.

Abstract
Description
しかし、開封口がきれいにカットされないと、開封口が唇に触れると不快に感じてしまう。特に、ピロー包装袋を用いたゼリー食品では、背中シールが開封口の近くに配置されているため、背中シールが唇に刺さって不快に感じてしまう。
従来の袋入りゼリー食品51では、横シール72を切断して開封口68を形成するときに、開封口68が背中シール71に引っ掛かる。開封口68が背中シール71に引っ掛かると、開封口68が必要以上に大きくなったり、逆に開封口68が十分に開口しなかったりするという問題が頻発する。
図6(a)の様に、開封口68が中央側に向かって進行すると、包装袋60が大きく切り取られて、開封口68が必要以上に大きくなる。このため、図7(a)の様に、こんにゃく入りゼリー55がこぼれたり、飛び出したりする。
一方、図6(b)の様に、開封口68が上端に向かって進行すると、包装袋60が小さく千切れて、開封口68が小さくなり十分に開口しない。このため、図7(b)の様に、包装袋60を押してもこんにゃく入りゼリー55が良好に押し出されない。
消費者が強い力を加えて背中シール71を引き裂き、勢い余って包装袋60を引き千切るからである。このため、開封口68から勢いよくこんにゃく入りゼリー55が飛び出してしまう。
本発明は、横シールを切断して開封口を形成するときに、開封口が背中シールに引っ掛からずに、適切に形成される内容物入りピロー包装袋を提案することを目的としている。
本発明の第一実施形態に係る袋入りゼリー食品1について説明する。
図1は、本発明の第一実施形態に係る袋入りゼリー食品1を示す図であって、(a)正面図、(b)裏面図である。図1(b)においてハッチングを付した部位は、熱シール(熱溶着)された部位を示す。
図2は、袋入りゼリー食品1を示す図であって、(a)平面図、(b)底面図、(c)左側面図である。
縦方向に直交する方向のうち、袋入りゼリー食品1の幅方向を「横方向」という。正面から見たときに、横方向のうち、開封口18が形成される突出部23側を「右側」、後退部24側を「左側」という。
縦方向に直交する方向のうち、袋入りゼリー食品1の厚み方向を「表裏方向」という。表裏方向のうち、背中シール21のない面側を「表面側」、背中シール21が形成された面側を「裏面側」という。
こんにゃく入りゼリー5は、ゼリー溶液にこんにゃく精粉が含まれる点に特徴がある。こんにゃく入りゼリー5は、少なくともゲル化剤およびこんにゃく精粉を含有していれば、任意の材料をさらに含有してもよい。こんにゃく入りゼリー5は、こんにゃく精粉を含有することにより、弾力性の高い独特の歯ごたえを有する。
収容部12は、一枚のフィルムのうち、熱溶着されていない非シール部であって、こんにゃく入りゼリー5が充填封入される部位である。
背中シール21は、包装袋10の背面の中央において縦方向のほぼ全域に亘って形成される。背中シール21は、縦シールまたはセンターシールとも呼ばれる。
横シール22は、上端において横方向の全域に亘って形成される。横シール27は、下端において横方向の全域に亘って形成される。
具体的には、正面から見て、横シール22の右側に突出部23が配置され、左側に後退部24が配置され、中央よりも右側に連結部(内側縁部)25が配置される。
突出部23と後退部24は、横方向に沿う。連結部25は、縦方向に沿って、突出部23の左端と後退部24の右端を連結する。連結部25は、包装袋10の内側縁となる。
突出部23、後退部24および連結部25は、ほぼ同一の幅寸法(シール幅)に形成される。
連結部25が包装袋10の中央よりも右側に配置されるため、狭小収容部14の横方向の長さは、包装袋10の幅の1/3程度になる。
収容緩衝部16を設けることにより、いわゆる角立ちを防止できる。これにより、複数の袋入りゼリー食品1を袋や箱に詰め込んだときに、包装袋10の角立ちが、隣接する他の包装袋10に刺さってピンホールを発生させることを防止できる。
通常、横シールを形成するための横シール形成装置を備えたピロー包装機では、加熱されたヒートシールバー(横シールバー)を、ピロー包装袋の正面側に配している。そして、ピロー包装袋の横シールは、このヒートシールバーによってフィルムの所定部位を横方向に押圧されて正面側と裏面側のフィルム同士がヒートシールされることで形成される。
このとき、加熱を受けた横シール正面側は、冷却されると裏面側に比べて収縮し易い。そのため、従来のピロー包装袋では、横シールと収容部との境界線を軸にして、横シールが正面側に倒れこむ現象が発生する。これにより、シール幅が一定である従来の横シールでは、角立ち部がより鋭角となり易い。
したがって、包装袋10の収容部12にこんにゃく入りゼリー5を密封充填して、袋入りゼリー食品1を製造した状態で、互いに隣接する包装袋10同士の突き刺しや擦過傷によるピンホールの形成が抑制される。
この結果、横シール22,27のシール幅は、中央部では広く、両側端では狭くなる。収容緩衝部16の寸法や数等は、フィルムの伸びや引っ張り強度等の特性や、包装袋10の大きさや内容物の充填量等に応じて、適宜選択される。
まず、通常のこんにゃく入りゼリーを作る場合と同様、ゲル化剤およびこんにゃく粉を含有させたこんにゃく入りゼリー溶液を調製する。こんにゃく入りゼリー溶液には、ゲル化剤およびこんにゃく粉の他に、糖類、果汁、香料、酸味料、着色料などを、必要に応じて加えることができる。
袋入りゼリー食品1において、包装袋10に封入されたこんにゃく入りゼリー5は、以下のようにして食べられる。
消費者は、まず、切断用ノッチ26を利用して包装袋10の上部を横方向に引き裂く。これにより、包装袋10は狭小収容部14で開封され、狭小収容部14の横方向全域にわたる開封口18が形成される。
このとき、消費者の唇に開封口18が当たるため、開封口18がギザギザになったり、背中シール21の角部が唇に触れたりすると、不快に感じてしまう。
したがって、こんにゃく入りゼリー5が開封口18からこぼれたり、飛び出したりするという問題、または包装袋10を押してもこんにゃく入りゼリー5が押し出されないという問題は発生しない。
また、開封口18が背中シール21に引っ掛からないので、開封口18が適切に形成される。したがって、適量のこんにゃく入りゼリー5が開封口18から押し出される。
本発明の第二実施形態に係る袋入りゼリー食品2について説明する。
なお、第一実施形態に係る袋入りゼリー食品1と同一の部位については、同一の符号を付して、その説明を省略する。
図5は、袋入りゼリー食品2を示す図であって、(a)平面図、(b)底面図、(c)左側面図である。
具体的には、正面から見て、横シール22の右側に突出部23が配置され、左側に後退部34が配置され、中央よりも右側に連結部(内側縁部)25が配置される。
突出部23は、横方向に沿う。後退部34は、斜め下側に向かって延びる。後退部34は、横方向に対して、下側に緩やかな角度で傾斜する。より詳細には、後退部34の中央よりも右側は、横方向に対して約40°の角度で傾斜する。後退部34の中央から左側は、横方向に対して約15°の角度で傾斜する。
連結部25は、縦方向に沿って、突出部23の左端と後退部34の右端を連結する。突出部23、後退部34および連結部25は、ほぼ同一の幅寸法(シール幅)に形成される。
また、開封口18が背中シール21に引っ掛からないので、開封口18が適切に形成される。したがって、適量のこんにゃく入りゼリー5が開封口18から押し出される。
また、後退部34は、二段階に傾斜する。つまり、中央よりも右側が斜め下側に大きく後退し、中央よりも左側が緩やかに後退する。このため、突出部23と後退部34の縦方向の距離が大きくなる。これにより、突出部23を切断して開封口18を形成するときに、突出部23と後退部34を把持しやすくなる。したがって、突出部23を切断するときに、消費者が力の調整をしやすく、開封口18を適切に形成できる。
すなわち、内容物は、包装袋10の下部を押し潰したときに、開封口18から押し出されるもの(流動物)であればよい。流動物は、マーガリン、ショートニング、チョコレートなどの半固形物も含まれる。
充填包装は、無菌充填包装に限らない。
また、切断用ノッチ26の大きさや切り込み深さ等は、任意に設定できる。
これにより、開封口18が横方向に沿って良好に形成される。開封口18が必要以上に大きくなったり、逆に開封口18が十分に開口しなかったりすることを防止できる。
横切性(直進カット性)に優れた包装用フィルムは、例えば、東レ株式会社「YT42トレファン」、デンカ株式会社「カラリヤンY」等が挙げられる。
収容部12に収容緩衝部16が設けられない場合であってもよい。
