Description

本発明は、チャック付き袋に関し、特に、シート材料からなる前後一対の正面部を備え、これらの一端に設けられたチャック機構により再封止可能となっているチャック付き袋に関する。   The present invention relates to a bag with a chuck, and more particularly to a bag with a chuck that includes a pair of front and rear front portions made of a sheet material and can be resealed by a chuck mechanism provided at one end thereof.

シート材料からなる前後一対の正面部を備える袋として、ピロー袋やガセット袋等が知られている。これらの袋は、例えばプラスチック製の積層フィルムをシート材料として使用して、予め設計された所定の形状に裁断された一枚又は複数枚のシート材料(フィルム材料)に、公知の各種の折曲げ加工や切断加工を施すことにより、内容物を収容するための袋容器として形成される。   A pillow bag, a gusset bag, and the like are known as a bag having a pair of front and rear front portions made of a sheet material. These bags are made of various kinds of well-known folds into one or a plurality of sheet materials (film materials) cut into a predetermined shape using, for example, a plastic laminated film as a sheet material. By performing processing and cutting processing, it is formed as a bag container for containing the contents.

シート材料からなる袋は、内容物として液体状のものや、粉状や粒状、その他の固形物など広範囲で使用でき、また簡易に且つ安価に収容できることから、その用途が拡大している。そして、例えば内容物を封入した状態から、上端取出し口を開封して内容物を取り出した後に、上端取出し口を再封止できるようにして、内容物を保管しながら繰り返し取り出すことができるようにした袋や、上端取出し口を上方に配置した状態で自立可能に構成した袋も開発されている(例えば、特許文献1、特許文献2参照)。   Bags made of sheet material can be used in a wide range of contents such as liquids, powders, granules, and other solid materials, and can be stored easily and inexpensively, so that their uses are expanding. And, for example, from the state in which the contents are sealed, after opening the upper end outlet and taking out the contents, the upper end outlet can be resealed so that the contents can be repeatedly taken out while being stored. Bags that are configured to be self-supporting in a state where the upper end outlet is disposed upward have also been developed (see, for example, Patent Document 1 and Patent Document 2).

特開2005−104561号公報JP-A-2005-104561 特開2005−231677号公報JP 2005-231677 A

シート材料からなる前後一対の正面部を備えるピロー袋やガセット袋等の袋を再封止可能に形成した場合、開封された上端取出し口から内容物を取り出す際に、上端取出し口の開口形状を大きく保持しておくことが困難になり易い。このため、例えば前後一対の正面部と、これらの正面部の内側にV字状に折込み可能な左右一対の側面折込み部とを備える特許文献1のガセット袋では、側面折込み部に、折込み中心線を挟んだ両側の部分を山折り状に外側に折り返して互いに接合することで帯ひれ状縦リブを中央部分に設けることにより、上端取出し口の開口形状を大きく保持できるようにする工夫がなされている。   When a bag such as a pillow bag or a gusset bag having a pair of front and rear front parts made of sheet material is formed so as to be resealable, the opening shape of the upper end outlet is taken out when the contents are taken out from the opened upper end outlet. It tends to be difficult to keep large. For this reason, for example, in the gusset bag of Patent Document 1 including a pair of front and rear front portions and a pair of left and right side folding portions that can be folded in a V shape inside these front portions, the folding center line is formed in the side folding portion. The device has been devised so that the opening shape of the upper end outlet can be kept large by providing a strip-like vertical rib at the center part by folding the sides on both sides outside in a mountain fold shape and joining them together. Yes.

一方、特許文献2のチャックテープ付き袋のように、前後一対の正面部が、上辺部に沿って内側に設けられたチャック機構により再封止可能となっている袋では、チャック機構を取り付けた上部に側面折込み部を設けることができないことから、上端取出し口の開口形状を大きく保持しておくことが難しい。   On the other hand, as in a bag with a chuck tape of Patent Document 2, a pair of front and rear front portions can be resealed by a chuck mechanism provided inside along the upper side portion, and the chuck mechanism is attached. Since the side folds cannot be provided at the top, it is difficult to keep the opening shape of the upper end outlet large.

本発明は、再封止可能なチャック機構を開放して形成した上端開口の開口形状を、相当の大きさに容易に保持しておくことのできるチャック付き袋を提供することを目的とする。   An object of the present invention is to provide a bag with a chuck that can easily hold the opening shape of an upper end opening formed by opening a resealable chuck mechanism in a considerable size.

本発明は、シート材料からなる前後一対の正面部を備え、これらの正面部の上辺部に沿って内側に設けられたチャック機構により再封止可能となっているチャック付き袋であって、前記前後一対の正面部の少なくとも一方の内側面には、前記チャック機構に近接して、着脱可能な係着部及び被係着部からなる開口保持機構が設けられており、前記チャック機構を開放して上端開口を形成した際に、前記係着部を前記被係着部に係着させることで折曲り角部を形成して、前記上端開口の開口状態を保持させるチャック付き袋を提供することにより、上記目的を達成したものである。   The present invention is a bag with a chuck comprising a pair of front and rear front parts made of a sheet material, which can be resealed by a chuck mechanism provided inside along the upper side of these front parts, At least one inner surface of the pair of front and rear front portions is provided with an opening holding mechanism that includes a detachable engaging portion and an engaged portion in proximity to the chuck mechanism, and opens the chuck mechanism. When the upper end opening is formed, a bent corner portion is formed by engaging the engaging portion with the engaged portion, thereby providing a bag with a chuck that maintains the open state of the upper end opening. The above-mentioned purpose has been achieved.

本発明のチャック付き袋によれば、再封止可能なチャック機構を開放して形成した上端開口の開口形状を、相当の大きさに容易に保持しておくことができる。   According to the bag with a chuck of the present invention, the opening shape of the upper end opening formed by opening the re-sealable chuck mechanism can be easily held in a considerable size.
