Description

本発明は、容易に引き裂くことができる液体等収納袋に関するものであり、更に詳細には、液体等注出部に向けて折線上に穿設した直線状の切れ目を設けたことにより、直線状の切れ目から引き裂いて容易に注出できる易引裂性の液体等収納袋に関するものである。 The present invention relates to a liquid storage bag that can be easily torn, and more specifically, by providing a linear cut perforated on a fold line toward a liquid extraction portion. The present invention relates to a storage bag for easily tearable liquid that can be easily torn out from the cuts .

この種の醤油、ソース等の液体調味料、バター、マーガリン、マヨネーズ等の粘性を有する粘性食品、シャンプー、洗剤、化粧品等の液体や粘性を有する液体、胡椒、塩、粉状の入浴剤等の粉体、粒体を収納して、必要なときに一部を引き裂いて注出するワンウェイの液体等収納袋は各種開発され多方面で使用されている。   This type of soy sauce, liquid seasonings such as sauces, viscous foods such as butter, margarine and mayonnaise, shampoos, detergents, cosmetics and other liquids and viscous liquids, pepper, salt, powdered baths, etc. Various types of one-way liquid storage bags have been developed and used in various fields that store powder and granules and tear them out when necessary.

従来、一般的には液体等収納袋の外周縁にくの字状の切り込みを入れて、その切り込みから引き裂いていたが、近年では、液体等収納袋の外周縁に極微細な切り込みを連続して多数形成して、何処からでも引き裂ける液体等収納袋も開発されている。   Conventionally, generally, a U-shaped cut was made on the outer peripheral edge of a storage bag for liquid etc., and it was torn from that cut, but in recent years, an extremely fine cut was continuously made on the outer peripheral edge of the storage bag for liquid etc. A liquid storage bag has been developed that can be formed in large numbers and torn from anywhere.

また、先に開示されている、上下二層によるビニル材により上層部ビニル材と下層部ビニル材との間に極薄のプラスチック樹脂材を挿入し、当該プラスチック材は一定部位が撓折することにより内容物が取り出されるよう施し、上下層ビニル材がプラスチック材を挟むよう接着される際に、取り出し口用に一部突出した形を呈した調味料液体等を内包する部分として造られる空洞部を、上層部ビニル材の下面とプラスチック材上面との間に施し、前記屈折される一定部位は前記空洞部の取り出し口部分でプラスチック材が撓折するよう切れ目を施すことで、当該突出空洞部位のみより内容物を排出可能とするもの(特許文献1参照)がある。

In addition, an ultra-thin plastic resin material is inserted between the upper layer vinyl material and the lower layer vinyl material by the vinyl material having two layers above and below, and the plastic material is bent at a certain portion. When the upper and lower layer vinyl materials are bonded so as to sandwich the plastic material, the hollow portion is formed as a part containing a seasoning liquid or the like that partially protrudes for the outlet. Is applied between the lower surface of the upper-layer vinyl material and the upper surface of the plastic material, and the certain portion that is refracted is cut so that the plastic material bends at the outlet portion of the cavity portion, thereby the projecting cavity portion. In some cases, the contents can be discharged (see Patent Document 1).
Japanese Patent Laid-Open No. 10-194333 (FIG. 7)

然し乍ら、従来の液体等収納袋の外周縁にく字状の切り込みを入れて、その切り込みから引き裂いて注出するものや、極微細な切り込みを連続して多数形成して液体等収納袋を引き裂いて注出するものでは、幼い子供が悪戯で引き裂いてしまうことが屡々あり、また、上下二層によるビニル材の間に極薄のプラスチック樹脂材を挿入し、当該プラスチック材は一定部位が撓折することにより内容物が取り出されるよう施したものでは、液体等収納袋を製造するときに極薄のプラスチック樹脂材を挿入しなければ成らず、パーツの数が増えることからコスト高と成ると共に、不用意に折って注出される虞れもあるものである。   However, the conventional liquid storage bag is cut in the shape of a square, and the liquid storage bag is torn and torn out from the cut, or a lot of extremely fine cuts are continuously formed to tear the liquid storage bag. In many cases, a young child can tear by mischief.In addition, a very thin plastic resin material is inserted between two upper and lower vinyl materials, and a certain part of the plastic material is bent. In order to take out the contents by doing so, it is necessary to insert an ultrathin plastic resin material when manufacturing a storage bag for liquids, etc. There is a possibility that it may be accidentally folded and poured out.
