Abstract

<P>PROBLEM TO BE SOLVED: To provide a packaging bag holding a quality retaining agent or the like which prevents the packaging bag from breaking caused by an expanding gas even if the bag is heated rapidly with a microwave oven or the like by allowing only the gas to escape outside while preventing a content from flowing out. <P>SOLUTION: Unsealed zigzagged passages 5 leading from the inside to the outside of the packaging bag are formed on both side peripheries of the packaging bag which are subjected to a sealing process, symmetrically. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、品質保持剤等を内部に収容する包装袋に関するものである。   The present invention relates to a packaging bag that contains a quality-preserving agent and the like inside.

食品の品質保持剤等を収容する包装袋は、通常層構造を有しており、例えば外側の基材層、中間層、及び品質保持剤等を内包する最内層から構成され、周縁部にシールが施されたものが提案されている（例えば、特許文献１参照。）。また、水分透過性フィルムと透過孔を有する樹脂フィルムとを積層してラミネートフィルムを構成し、その外縁を封じて包装袋としたものも実用化されている。
特開平１１−２２７８３９号公報 A packaging bag that contains a food quality preservation agent or the like usually has a layer structure, and is composed of, for example, an outer base layer, an intermediate layer, and an innermost layer that contains the quality preservation agent and the like, and is sealed at the periphery. Has been proposed (for example, see Patent Document 1). Also, a laminate film is formed by laminating a moisture permeable film and a resin film having a permeable hole, and the outer edge is sealed to form a packaging bag.
JP-A-11-227839

ところで、上記のような包装袋にあっては、表面に部分的に微小な孔を外部から中間層にまで貫通させて設け、最内層の膜はそのまま残しており、加熱時に膨張したガスが最内層の膜を破ることで、そのガスを孔を通して透過させている。   By the way, in the packaging bag as described above, a minute hole is partially penetrated on the surface from the outside to the intermediate layer, and the innermost layer film is left as it is. By breaking the inner layer, the gas is permeated through the holes.

このため、電子レンジ等により急激に加熱された場合に、膨張したガスにより破袋が生じ、内容物（収容物）が流出してしまうという問題点があった。   For this reason, when heated rapidly with a microwave oven etc., there existed a problem that a bag breakage will arise by the expanded gas, and the contents (contained material) will flow out.

本発明は、上記のような問題点に鑑みてなされたもので、電子レンジ等による急激な加熱があっても、膨張したガスによる破袋を防止でき、ガスのみを外部に放出させて内容物の流出を防止可能な包装袋を提供することを目的としている。   The present invention has been made in view of the above problems, and can prevent bag breakage due to expanded gas even when there is rapid heating by a microwave oven, etc. It aims at providing the packaging bag which can prevent the outflow of the.

上記の目的を達成するため、本発明は、次のように構成する。   In order to achieve the above object, the present invention is configured as follows.

シールを施す周縁部の所望の箇所に、内部から外部に通じるジグザグ形状の非シールの回路を設けたことを特徴とする。   A zigzag-shaped non-seal circuit that communicates from the inside to the outside is provided at a desired portion of the peripheral portion to be sealed.

また、非シールの回路は、包装袋の両側に設けたことを特徴とする。   The non-sealed circuit is provided on both sides of the packaging bag.

本発明によれば、電子レンジ等による急激な加熱があっても、膨張したガスによる破袋を防止でき、ガスのみを外部に放出させて内容物の流出を防止できるという効果がある。   According to the present invention, even if there is abrupt heating by a microwave oven or the like, there is an effect that bag breakage due to expanded gas can be prevented, and only the gas is released to the outside to prevent outflow of contents.

以下、本発明の実施例を図面について説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は本発明に係る包装袋の構成を示す図である。   FIG. 1 is a diagram showing a configuration of a packaging bag according to the present invention.

この包装袋は、内部に食品の品質保持剤等を収容するもので、本実施例では、基材層である外層１と、中間層２と、最内層３の層構造を有し、品質保持剤４が内包されている。   This packaging bag contains a food quality-preserving agent or the like inside, and in this embodiment, has a layer structure of an outer layer 1, a middle layer 2, and an innermost layer 3 as a base material layer, and maintains the quality. Agent 4 is included.

図２は上記包装袋の周縁部の構成を示す図である。シールを施す周縁部の所望の箇所に、内部から外部に通じるジグザグ形状の非シールの回路５が設けられている。ここでは、非シールの回路５は、包装袋の両側に設けられている。そして、電子レンジ等による急激な加熱があった場合は、内部で膨張したガスはこの非シールの回路５を通って外部に放出されるので、膨張したガスによる破袋を防止でき、ガスのみを外部に放出させて、内容物の流出を防止することができる。   FIG. 2 is a view showing the configuration of the peripheral edge of the packaging bag. A zigzag-shaped non-seal circuit 5 that communicates from the inside to the outside is provided at a desired portion of the peripheral edge to be sealed. Here, the non-seal circuit 5 is provided on both sides of the packaging bag. When there is rapid heating by a microwave oven or the like, the gas expanded inside is discharged to the outside through this non-sealed circuit 5, so that the bag can be prevented from being broken by the expanded gas, and only the gas is discharged. It can be discharged outside to prevent the outflow of contents.

ここで、上記の非シールの回路５は、周縁部に設けているので、ガス膨張時の圧力が均等に配分される。また、この非シールの回路５は、図２に示すようなジグザグ形状で、膨張したガスの直進部分と、直進して衝突する幅（面積）の広い部分と、そこから右もしくは左に折れて直進する部分と、直進して再度衝突する部分の経路が順次形成されており、ガスのみが放出されて、内容物は途中で止まって外部には流出しにくい経路となっている。この経路の深度（深さ）や幅などの寸法は、内容物の種類や使用目的に応じて決めることができる。   Here, since the non-sealed circuit 5 is provided at the peripheral edge, the pressure during gas expansion is evenly distributed. Further, the non-sealed circuit 5 has a zigzag shape as shown in FIG. 2, and a straight portion of the expanded gas, a wide portion (area) where the straight gas collides, and a right or left portion is folded from there. A straight path and a path of a straight line and a part that collides again are formed in order, and only the gas is released, and the contents stop halfway and are difficult to flow out. Dimensions such as the depth (depth) and width of this route can be determined according to the type of contents and the purpose of use.

本発明は、品質保持剤全般に適用することができる。   The present invention can be applied to quality maintenance agents in general.
