Description

[Detailed Description of the Invention] The present invention relates to a packaging bag with an outlet for storing sheets of paper, cloth, etc. impregnated with a drug such as alcohol.

In recent years, disposable wet napkin products in which sheets of paper, cloth, etc. are impregnated with chemicals such as alcohol have come into widespread use.

There are many types of storage containers, such as bags and boxes, but most of these are bulky because they are made of synthetic resin injection molded products or vacuum molded products.

Among these containers, bags with opening/closing lids are particularly inexpensive and easy to manage in terms of production technology.

As shown in Fig. 1, there is a bag of this kind that has an opening formed by cuts on three sides in a part of the bag.
The opening did not stop at the cut end of the bag, and there was a risk that the bag body other than the opening would be torn.

Furthermore, in Japanese Patent Application Laid-open No. 57-163656, a portion located on the outside of the packaging wall and functioning as a tensioning tab is
A means for opening the package sealed in the directional plastic membrane is indicated by a weld which has a projection and serves as a point of application for a force directed in a direction opposite to the direction of the tensioning force.

This invention still has the same drawbacks as described above.

The present invention is a packaging bag which eliminates the above-mentioned drawbacks and which can prevent the bag from being opened more than necessary.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

As shown in FIG. 2, the present invention consists of a synthetic resin containing a uniaxially stretched plastic film or a laminated material made of a synthetic resin and aluminum foil, one side of which is folded back, and one side of a bag 2 has a fixed overlapping part 1. A notch 3 with a width for forming an outlet is provided in a direction perpendicular to the stretching direction of the uniaxially stretched plastic film.

As shown in FIG. 3, this is a packaging bag with a take-out opening, on which a label 4 having a pressure-sensitive adhesive layer on the back surface is attached, covering the notch 3 of the bag and reaching the overlapping part 1.

Since the present invention is constructed as described above, when the label 4 is peeled off, the notch 3 made in the bag is removed at the same time.
The empty bag is torn along the stretching direction of the uniaxially stretched film to form an outlet. Furthermore, since the unsealed outlet reliably stops at the end of the overlapping portion of the bag, unnecessary tearing can be prevented.

Furthermore, when the opened label is returned, the bag is prevented from being pulled and deformed to a minimum, so it can be resealed in a secure position.

Furthermore, the purpose can be sufficiently achieved by simply folding and fixing one side of the bag, which is a special process, so that the bag can be manufactured easily.
