JPS5830495Y2 - Cosmetic packaging bag - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an enclosure bag with an opening/closing lid that can be used as a simple container for cosmetics, etc., particularly in which multiple sheets of fiber material are impregnated with liquid or coated with powder.

In recent years, disposable wet napkin-like products impregnated with fiber materials such as cosmetics and drugs have come into widespread use.

Cosmetics are used for a wide variety of purposes, such as wiping off dirt, and medicines are used for disinfection, and there are many types of storage containers.

However, among these methods, a simple enclosure bag with an opening/closing lid is a particularly reasonable method because it is low in cost and easy to manage in terms of production technology.

Conventionally, this type of method has been used, for example,
As disclosed in Japanese Patent No. 47018, an inner lid is formed on one side of the bag, a take-out opening is formed in the inner lid, and an outer lid is stacked on top of the inner lid. There is a method of applying pressure-sensitive adhesive to the facing outer lid surfaces and repeatedly opening and closing the lid.

However, the problem with these bags is that, at the point of sale, there is a lack of proof that the product is being used for the first time, that is, a sealing element. It was difficult to tell whether it was a real thing or not, which caused a sense of anxiety, and there was a strong desire for improvements.

In addition, in the structure disclosed in the above-mentioned Japanese Utility Model Publication No. 49-47018, the pressure-sensitive adhesive and the contents are always in contact with each other at the opening, so the odor and components of the adhesive may be released. It had problems such as transferring to the contents and causing deterioration.

This invention was developed in view of these backgrounds,
What are its characteristics?

a bag body formed of an airtight sheet material and having an opening for taking out the contents; a film larger than the opening that closes the opening; a film that covers the opening and has one end fixed to the bag;
Furthermore, the bag includes a lid member larger than the film, and an adhesive layer provided on the inner surface of the lid member corresponding to the opening of the bag body and provided in a wider area than the film.

Examples of the present invention will be described below based on the drawings. Polyethylene, polypropylene, polyester.

A flat bag body 1 made of an airtight sheet material obtained from a composite material of a synthetic resin film such as boriamite or a composite material of these and aluminum foil, etc., has a circular, oval, thin rectangular, caltrop shape, etc. A rectangular opening 2 is provided, and a film 3 made of synthetic resin or aluminum having a shape similar to the opening 2 and larger than the opening 2 is closed off from inside the bag 1, and then one end is closed. is fixed to the bag body 1 to form a fixed part 6, and an acrylic ester or rubber is attached to the surface facing the opening 2 of the airtight lid member 4 made of synthetic resin, film, etc. larger than the film 3. It is formed by forming a pressure sensitive adhesive layer 5 such as a type of adhesive.

In such an enclosure bag, a fiber material is sealed in advance before use.

The fiber materials mentioned here include synthetic or natural fibers such as paper, woven fabric, non-woven fabric, cotton, gauze, etc.

When using the present invention constructed as described above, first open the lid member 4 provided on the bag body 1 as shown in FIG.
The film 3 is adhered to the pressure-sensitive adhesive layer 5 coated on the bag body 1 in such a manner that it passes through the opening 2 of the bag body 1 and is pasted thereon.

This phenomenon only occurs during the first use.
In subsequent use, the film 3 attached to the lid member 4 remains as it is and cannot return to its original position.

Therefore, once the lid member is opened, there is a film 3 inside the bag.
Since there is no remaining film, the original purpose of the sealing function has been sufficiently achieved, and since the film 3 is always attached to the pressure-sensitive adhesive part over an area larger than the opening 2, it is possible to prevent direct contact with the contents. No contact occurs and the quality is stable.

As described above, the present invention has many advantages and is extremely effective.
