Description

【0001】
【発明の属する技術分野】
本件は使い捨てトレイに関し、より詳しくは、例えばテーブルに置いたときのトレイの安定性を向上させた使い捨てトレイに関する。
【0002】
【従来の技術】
従来、パルプモールドで構成されたトレイについては、例えば特開平11−227736号公報、特開平8−217050号公報、実開昭64−20419号公報に開示されているように、トレイの内側に紙コップ等を載置する凹状収納部を設け、また、トレイ本体のねじれに抵抗する剛性を与えるため、トレイの内側にリブ部を設け、また、トレイの外周縁に沿ってフランジ部を設けたトレイが知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、これら従来のトレイは、例えば特開平11−227736号公報、実開昭64−20419号公報のように、凹状収納部が直接トレイ本体の底部を構成するため、例えばトレイをテーブルに置いたとき、凹状収納部の形状によってはトレイの安定性が損なわれることがあった。また、特開平8−217050号公報には、トレイの外周部を囲む側面板を設けた合成樹脂製のトレイが開示されているが、該側面板が垂直の場合、トレイを収納するとき重ねて収納することが困難となり、また該側面板がトレイの外方に向かって斜めに突出している場合、トレイの収納時に重ねることはできるが、側面板が外方に突出した分、かさばって収納しにくくなるということがあった。
【0004】
本発明はかかる事情に鑑みなされたもので、収納時にかさばることなく、例えばテーブルに置いたときに確実な安定性を有する使い捨てトレイを提供することにある。
【0005】
【課題を解決するための手段】
前記課題を解決するための本発明の使い捨てトレイは、カナダ標準フリーネス(CSF)が550ml以下のパルプからなるパルプモールド製の薄肉トレイであって、該トレイは凹状収納部を有し、かつ、該凹状収納部は底部の縁辺に沿う側壁部の複数箇所に設けられた逆T字形スリットを有し、前記トレイの外周縁の少なくとも一部はトレイの内向に湾曲され、該湾曲周縁部からトレイの底部方向に、突出片がトレイの最深部と同じ深さに先端が位置するように突出配置されていることを特徴とする、使い捨てトレイである。
【0006】
【発明の実施の形態】
以下、図面を参照して本発明の実施の一形態について詳細に説明するが、本発明はこれに限定されるものではない。図1は本発明の実施の一形態である使い捨てトレイの斜視図、図2は図1の使い捨てトレイの平面図である。図中の符号1はトレイ、2は周縁部、2a,2b,2c,2dは辺、3a,3bは凹状収納部、3a’,3b’は凹状収納部の底の縁辺、4はスリット、4aは押え片、5a,5bは突出片、5a’,5b’は筋部、6a,6bはリブ部、6a’,6b’はリブ部の凸部、7は凹部、7a,7b,7c,7dは凹部の縁辺である。
【0007】
図1及び図2に示す使い捨てトレイは、低コストで廃棄処分も容易でかつ再資源化も可能なパルプモールド製で、全周縁が逆U字形に折返されたフランジを形成し、隅角部が円弧を描いた概ね方形または角形の周縁部2を有する。該パルプモールドは、カナダ標準フリーネス(CSF)が550ml以下のパルプで構成するのが安定した強度を得るために望ましい。このトレイ1の中心部には凹部7が形成され、該凹部7の縁辺7aから周縁部の縁辺2aの中心に向かってリブ部6aが伸び、また、縁辺7bから周縁部の辺2bの中心に向かってリブ部6bが伸びている。
【0008】
周縁部2とリブ部6a,6bは凸部を形成し、周縁部2とリブ部6a,6bに囲まれた部分は、それぞれ凹状収納部3a,3bを形成している。凹状収納部3a,3bは円弧状の頂部を具えた概ね三角形で、それら凹状収納部の底の縁辺3a’,3b’に沿い、その壁面にそれぞれ水平に伸びるスリットと、これら各スリットの中心から上方に伸びるスリットを組み合わせ全体が逆T字形となるスリット4が設けられている。また、スリット4が設けられている部分は凹状収納部の内側に突出するように湾曲して構成されている。
【0009】
凹状収納部3a,3bは飲料容器を固定する部分でもある。これらの凹状収納部に例えば、飲料水の紙コップを押し込むと、スリット4の周辺の押え片4aの部分を押し広げ、前記紙コップの下端縁を水平方向の3本のスリットで受けると共に、下半部の周囲6箇所を、押え片4aが板ばねのように外側からしっかり押えて固定する。
【0010】
周縁部の辺2aの中心部には、トレイ1の底部に向かって伸びる突出片5aが設けられている。また、周縁部の辺2bの中心部には、トレイ1の底部に向かって伸びる突出片5bが設けられている。これらの突出片5a,5bはトレイ1の周縁部の辺2a,2bの一部がそれぞれリブ部6a,6bの凸部6a’,6b’の位置まで湾曲し、該湾曲位置から、トレイ1の外周縁から外側に突出しないよう、トレイ1の底部方向に斜めに絞り込むようにして、凹状収納部3a,3bの最深部と同じ深さに先端が位置するように伸びている。さらに該突出片には、変形や折れ曲がりを防ぐための補強部分である筋部5a’,5b’が突出片の上下方向に形成されている。これら突出片がトレイの周縁部に設けられていることにより、トレイをテーブル等に置いたとき、突出片が脚台のようにトレイを支え、安定させる。また、突出片がトレイの中心方向からトレイの外方に向かって斜めに伸びており、かつ、突出片の先端はトレイの外周縁より外側には突出しないため、トレイを収納する際、かさばることなく積み重ねて収納することができる。
【0011】
【発明の効果】
以上、詳述したように、本発明によれば、収納時にかさばることなく、例えばテーブルに置いたときに確実な安定性を有する使い捨てトレイを提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a disposable tray, and more particularly, to a disposable tray with improved stability when placed on a table, for example.
[0002]
[Prior art]
Conventionally, with respect to a tray formed of a pulp mold, for example, as disclosed in JP-A-11-227736, JP-A-8-217050, and JP-A-64-20419, paper is provided inside the tray. A tray provided with a concave storage portion for placing a cup or the like, and provided with a rib portion inside the tray to provide rigidity that resists twisting of the tray body, and a flange portion provided along an outer peripheral edge of the tray. It has been known.
[0003]
[Problems to be solved by the invention]
However, in these conventional trays, for example, as described in JP-A-11-227736 and JP-A-64-20419, since the concave storage portion directly constitutes the bottom of the tray body, the tray is placed on a table, for example. At this time, the stability of the tray may be impaired depending on the shape of the concave storage portion. Japanese Patent Application Laid-Open No. Hei 8-217050 discloses a synthetic resin tray provided with a side plate surrounding an outer peripheral portion of the tray. However, when the side plate is vertical, the tray is stacked when storing the tray. If the side plate protrudes obliquely toward the outside of the tray when it becomes difficult to store the tray, it can be stacked when the tray is stored, but the bulk of the side plate protrudes outward to accommodate the tray. Sometimes it became difficult.
[0004]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a disposable tray which does not become bulky at the time of storage and has stable stability when placed on a table, for example.
[0005]
[Means for Solving the Problems]
A disposable tray according to the present invention for solving the above-mentioned problem is a pulp mold thin-walled tray made of pulp having a Canadian Standard Freeness (CSF) of 550 ml or less, the tray having a concave storage portion, and The concave storage portion has an inverted T-shaped slit provided at a plurality of locations on the side wall portion along the bottom edge, at least a portion of the outer peripheral edge of the tray is curved inward of the tray, and The disposable tray is characterized in that the protruding piece is disposed so as to protrude toward the bottom so that the tip is located at the same depth as the deepest part of the tray.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto. FIG. 1 is a perspective view of a disposable tray according to an embodiment of the present invention, and FIG. 2 is a plan view of the disposable tray of FIG. In the figure, reference numeral 1 denotes a tray, 2 denotes a peripheral portion, 2a, 2b, 2c, 2d denotes a side, 3a, 3b denotes a concave storage portion, 3a ', 3b' denotes a bottom edge of the concave storage portion, 4 denotes a slit, 4a Are holding pieces, 5a and 5b are protruding pieces, 5a 'and 5b' are streaks, 6a and 6b are ribs, 6a 'and 6b' are projections of ribs, 7 is a recess, 7a, 7b, 7c, and 7d. Is the edge of the recess.
[0007]
The disposable tray shown in FIGS. 1 and 2 is made of pulp mold that is low-cost, easy to dispose of, and can be recycled. The entire periphery forms an inverted U-shaped flange, and the corners are It has a substantially rectangular or square peripheral edge 2 which describes an arc. The pulp mold is desirably composed of pulp having a Canadian Standard Freeness (CSF) of 550 ml or less for obtaining stable strength. A concave portion 7 is formed at the center of the tray 1, and a rib portion 6 a extends from the edge 7 a of the concave portion 7 toward the center of the peripheral edge 2 a, and extends from the edge 7 b to the center of the peripheral edge 2 b. The rib part 6b extends toward it.
[0008]
The peripheral portion 2 and the rib portions 6a and 6b form a convex portion, and portions surrounded by the peripheral portion 2 and the rib portions 6a and 6b form concave storage portions 3a and 3b, respectively. The concave storage portions 3a, 3b are substantially triangular with an arc-shaped top, along the bottom edges 3a ', 3b' of the concave storage portions, the slits extending horizontally on the wall surfaces thereof, and the center of each slit. A slit 4 is provided which is formed by combining slits extending upward and forming an inverted T-shape as a whole. Further, the portion where the slit 4 is provided is curved so as to protrude inside the concave storage portion.
[0009]
The concave storage portions 3a and 3b are portions for fixing the beverage container. For example, when a paper cup of drinking water is pushed into these concave storage portions, the portion of the pressing piece 4a around the slit 4 is pushed open, and the lower edge of the paper cup is received by three horizontal slits, At six locations around the half, the holding piece 4a is firmly pressed from the outside like a leaf spring and fixed.
[0010]
At the center of the side 2a of the peripheral portion, a protruding piece 5a extending toward the bottom of the tray 1 is provided. A protruding piece 5b extending toward the bottom of the tray 1 is provided at the center of the side 2b of the peripheral portion. These protruding pieces 5a, 5b are such that the sides 2a, 2b of the peripheral edge of the tray 1 are curved to the positions of the convex portions 6a ', 6b' of the ribs 6a, 6b, respectively. In order not to protrude outward from the outer peripheral edge, the tray 1 is obliquely narrowed down toward the bottom of the tray 1 and extends so that the tip is located at the same depth as the deepest portion of the concave storage portions 3a and 3b. Further, the protruding pieces are formed with streaks 5a 'and 5b', which are reinforcing portions for preventing deformation and bending, in the vertical direction of the protruding pieces. By providing these protruding pieces on the peripheral edge of the tray, when the tray is placed on a table or the like, the protruding pieces support and stabilize the tray like a footrest. Also, since the protruding piece extends obliquely from the center of the tray toward the outside of the tray, and the tip of the protruding piece does not protrude outside the outer peripheral edge of the tray, it is bulky when storing the tray. It can be stored without stacking.
[0011]
【The invention's effect】
As described above in detail, according to the present invention, it is possible to provide a disposable tray that does not have to be bulky at the time of storage and has stable stability when placed on a table, for example.
