- the seal width XB of the peeling restricting portion 70 gradually increases from the tip portion 40 toward the upper seal portion 21A. For this reason, in the process of peeling of the peeling restricting portion 70, stress concentration is unlikely to be locally generated in the peeling restricting portion 70, and the peeling proceeds stably until the peeling is restricted by the peel restricting portion 70.
- the inner edge 73B of the side end 73 extends from the inner edge 72B of the second portion 72 in an inclined state so as to approach the upper seal portion 21A. Therefore, it is possible to secure a wide area for forming a cut line or the like above the vapor-sealing seal portion 30 in the first sheet 11 and the second sheet 12.
- the description related to the second embodiment is an example of the form that the pouch according to the present invention can take, and is not intended to limit the form.
- the pouch according to the present invention can take, for example, a combination of the following modification of the second embodiment described below and at least two modifications not inconsistent with each other.
- the shape of the vapor seal 30 can be arbitrarily changed.
- the side-side end portion 73 is omitted from the first connection portion 60, and the peeling regulating portion 70 is connected to the upper seal portion 21A.
- the seal width XB of the peeling restricting portion 70 becomes wider from the distal end portion 40 toward the upper seal portion 21A.
- the shape of the first portion 71 of the peeling restricting portion 70 is a shape in which the seal width XA becomes narrower from the distal end portion 40 toward the second portion 72.
- the second connection portion 80 is also provided with a peeling restricting portion.
- the peeling restricting portion of the second connection portion 80 has a shape according to the shape of the peeling restricting portion 70 of the first connection portion 60, for example.
- only the second connecting portion 80 is provided with a peeling restricting portion.
- each of the sheets 11 to 13 can be arbitrarily changed.
- the first sheet 11 and the second sheet 12 are configured by bending one sheet.
- each sheet 11 to 13 is configured by bending one sheet.

Abstract
Description
本発明の目的は、シールが剥離することにより形成された開口から多量の内容物が漏れるような状況が生じにくいパウチを提供することである。
図1および図2は第1実施形態のパウチ1の構成の一例を示している。パウチ1はいわゆるスタンディングパウチである。パウチ1が取り得る状態は、少なくとも開放状態および閉鎖状態を含む。なお、別の例ではパウチ1の形態は平パウチである。図1は開放状態のパウチ1を示し、図2は閉鎖状態のパウチ1を示す。パウチ1の開放状態は、パウチ1内に内容物100が投入されておらず、パウチ1の開口部15が開放されている状態である。パウチ1の閉鎖状態は、パウチ1内に内容物100が投入され、開口部15がシールされている状態である。内容物100は例えばソースを含む食品である。一例では、閉鎖状態のパウチ1がエンドユーザーに提供される。
シート11~13の各々は最外層、中間層、および、最内層を含む。最外層を構成する材料の一例は透明な材料である。透明な材料の一例はポリエチレンテレフタレートである。中間層は印刷層、第1の接着層、延伸ナイロン層、および、第2の接着層を含む。印刷層は最外層の内側に設けられる。一例では印刷層の外面に絵柄および商品説明のテキスト等が印刷される。第1の接着層は印刷層の内側に設けられる。延伸ナイロン層は第1の接着層の内側に設けられる。第2の接着層は延伸ナイロン層の内側に設けられる。各接着層を構成する材料の一例はドライラミネート接着剤である。最内層は第2の接着層の内側に設けられる。最内層を構成する材料の一例は無延伸ポリプロピレンである。
最初に、閉鎖状態のパウチ1が電子レンジ等の加熱手段(図示略)に配置され、加熱手段により加熱される。加熱が終了した後、図5に示されるようにパウチ1がエンドユーザーにより持ち運ばれる。次に、図6に示されるように、ノッチ22Aおよび切取線(図示略)に沿って上部シール部24を含む部分がエンドユーザーにより切り取られ、開口部15が開放される。次に、内容物100が開口部15を介してパウチ1の外部に取り出される。
閉鎖状態のパウチ1が加熱手段により加熱されることにより、内容物100から水蒸気が発生し、収容空間14の圧力が次第に上昇する。このため、第1のシート11と第2のシート12とが互いに離間する方向に膨張し、通蒸シール部30のうちの先端部40が剥離して開口31が形成される。先端部40が剥離した後、通蒸シール部30の剥離は第1のサイドシール部21に向けて進行する。第1の接続部60に剥離規制部61が設けられているため、例えば通蒸シール部30におけるシールの剥離は剥離規制部61のシール幅XAの最も広い部分で終了する。なお、内容物100から発生する水蒸気の量が少ない場合、通蒸シール部30におけるシールの剥離はシール幅XAの最も広い部分よりも先端部40に近い部分で終了する。
上記第1実施形態に関する説明は本発明に従うパウチが取り得る形態の例示であり、その形態を制限することを意図していない。本発明に従うパウチは例えば以下に示される上記第1実施形態の変形例、および、相互に矛盾しない少なくとも2つの変形例が組み合わせられた形態を取り得る。
図7~図12は第2実施形態のパウチ1の構成の一例を示している。第2実施形態のパウチ1は、通蒸シール部30の形状、特に接続部50の形状において第2実施形態のパウチ1と異なっている。以下、第1実施形態と同様の構成については説明を省略する。
最初に、閉鎖状態のパウチ1が電子レンジ等の加熱手段(図示略)に配置され、加熱手段により加熱される。加熱が終了した後、図11に示されるようにパウチ1がエンドユーザーにより持ち運ばれる。次に、図12に示されるようにノッチ22Aおよび切取線(図示略)に沿って上部シール部24を含む部分がエンドユーザーにより切り取られ、開口部15が開放される。次に、内容物100が開口部15を介してパウチ1の外部に取り出される。
閉鎖状態のパウチ1が加熱手段により加熱されることにより、内容物100から水蒸気が発生し、収容空間14の圧力が次第に上昇する。このため、第1のシート11と第2のシート12とが互いに離間する方向に膨張し、通蒸シール部30のうちの先端部40が剥離して開口31(図10参照)が形成される。先端部40が剥離した後、通蒸シール部30の剥離は第1のサイドシール部21に向けて進行する。第1の接続部60に剥離規制部70が設けられているため、例えば通蒸シール部30におけるシールの剥離は剥離規制部70の第1の部分71と第2の部分72との境界部分で終了する。
上記第2実施形態に関する説明は本発明に従うパウチが取り得る形態の例示であり、その形態を制限することを意図していない。本発明に従うパウチは例えば以下に示される上記第2実施形態の変形例、および、相互に矛盾しない少なくとも2つの変形例が組み合わせられた形態を取り得る。
