Opening/closing tool and pouch provided with same

Abstract

Provided is an opening/closing tool: that enables a pouch to easily be opened and closed with one hand; that does not open a pouch unnecessarily widely; that allows contents to be taken out even when attached to a narrow pouch; and that does not hinder the closing of a pouch due to granular or powdered contents etc. getting caught. A pair of hinges (21, 22) pivotably support a pair of opening parts (11, 12), and allow pivoting between a closed position (P1), and a standby position (P2) where the rear side of one opening part (12) is bent in such a manner as to become aligned with the under side of the other opening part (11). As a result of the pair of hinges (21, 22) approaching each other when positioned in the standby position (P2), the pair of opening parts (11, 12) are displaced to an open position (P3), where the pair of opening parts (11, 12) bend and open in the direction in which facing parts (11a, 12a) are forced apart.

Description

technical field [0001] The present invention relates to a shutter that can easily open and close a bag, and a bag including the shutter. Background technique [0002] Recently, various foods are accommodated as contents in soft bags (pouches) produced by laminating synthetic paper or synthetic resin films, for example. Wherein, as the contents, the bags containing reusable seasonings such as salt and pepper, seaweed bibimbap, tea leaves, etc. are provided with plastic joints, which can be opened and closed repeatedly (for example, refer to patent documents 1). [0003] In general, for example, if the pouch is produced by pasting together two films in the shape of a rectangle, the joining members made of plastic are provided along the short sides thereof. On the inner surface side of each of the two films, protrusions and recesses that can be engaged and separated from each other are provided substantially over the entire length of the short side. When opening the joining ...

Problems solved by technology

And, even if the contents are, for example, small grains, it is difficult to open the joint member slightly correspondingly, so that it can be opened approximately over the entire length.

Moreover, the following situation can frequently be caused, that is, when the fastener is closed, it is extremely difficult to engage the convex portion and the concave portion, and it is impossible to visually confirm whether the engagement is good, and only rely on the feeling of fingers, so even if you want to engage Good enough to move the finger to the other end of the joint, but it doesn't actually snap, and the joint doesn't close, and the closure isn't complete

[0007] And, on the basis of the structure that the fastener is opened to the left and right, for example, when it is attached to a small bag with a narrow width (for example, about 3 cm or less), it is basically difficult to open it, so there is a practical The problem that it cannot be installed on a small bag with a narrow bag width

[0008] In addition, for example, when the content is salt, seaweed bibimbap, tea leaves, etc., some of which include granular or powdery food, open the fastener so that the opening of the pouch faces obliquely downward, and pour out the content. It is taken out, but at this time, since the contents pass through the joint, the granular and powdery food enters the concave part of the joint, so when the joint is closed, the convex part cannot be well engaged in the structure of the joint The problem
