Abstract

PURPOSE:To quickly and securely reclose a bag with a simple structure after an opening of the bag is cut and contents have been taken out by providing a lock means at a member attached to an outer face of the opening of the bag. CONSTITUTION:When contents are taken out from a bag (a) with contents put and sealed, the bag is cut from an unsealing notch to unseal. Since folds 7, 7 folded inside an opening 1 can be fully opened outward in this state, the contents can be easily taken out. To reclose the opening 1 after the contents are taken out, a lock member a1 is held to fold the opening 1 backward, the lock member a1 is overlaid on a lock member a2, engaging protrusions 4, 4 at both ends are fitted into engaging holes 5, 5, and the opening 1 of the bag (a) is reclosed. Thus reclosing the bag once the bag is unsealed and the contents are taken out can be performed quickly and securely, while its structure is extremely simple.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag containing a synthetic resin sheet, film, cloth, paper or the like, and more particularly to a reclose bag having a locking means provided as a separate member on the opening side of the bag. is there.

[0002]

2. Description of the Related Art Conventionally, as a means for reclosing the opening after a bag is sealed and filled with a powdery material such as detergent, wheat flour, cereals, etc., a chuck, a clip, The vinyl belt was used.

[0003]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention In the case of a chuck as a locking means for reclosing after opening the bag on the opening side of the bag filled and sealed with the contents as described above, in the case of a zipper, Due to the fact that it is attached to the inside of the mouth edge, the opening is narrowed by welding both side edges of the bag, and the outflow of the contents is reduced accordingly. It becomes difficult to mount it in the folding part, and in the case of the stand-type pouch, when a chuck is attached, a dedicated machine is required to fill the contents. In addition, the contents may be caught in the chuck part and may not be closed. Since the clip is separate from the bag body, handling is not good. In the vinyl belt, the way to stop is not stable. There were various problems. The present invention was created in view of such problems, and an object thereof is to easily reclose the bag after the opening side of the bag body is cut and the contents are taken out. This is done so that it can be done quickly and reliably with such a configuration.

[0004]

In order to achieve the above object, in the present invention, there is a problem in that a member having locking means is provided and attached from the outside of the opening of the bag. We are trying to resolve That is, in the present invention, the locking means is provided on the member attached to the outer surface of the bag body on the opening side, and the opening of the once opened bag body is locked and sealed by the locking means of the above member. It has a composition.

[0005]

[Embodiment] The bag may have any shape and may be made of any material.
There are gusset folding bags, stand pouches, and the like, and the material is a synthetic resin sheet, film, cloth, paper, or the like.
The cut line for taking out the contents from the bag in which the contents are filled and sealed is provided with a perforation line for opening or a notch for opening without using scissors, a cutter, etc. In the case of resin sheets and films, whether the opening that is to be the opening of the bag should be pre-opened and closed by heat-sealing it, or by laminating another film on this part. Further, the material may be oriented by being stretched so that the material is torn from the notch portion. The contents to be put in the bag and sealed are typically detergents, wheat flour, grains and the like.

Embodiments of the present invention will be described below with reference to the drawings.
