Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a cosmetic enclosing bag, and in particular, a bag made of multiple fiber materials (non-woven fabric, paper, cut cotton for cosmetics, woven fabric, etc.)
This is a simple container for packaging cosmetic liquid, etc. in foam or foam impregnated with cosmetic liquid, etc., and relates to an enclosure bag with an opening/closing lid.

[Conventional technology]

2. Description of the Related Art In recent years, disposable products (wet tissues) in which fibrous materials such as nonwoven fabrics are impregnated with a cleaning solution for stain removal have come into widespread use.

There are many types of storage containers for disposable wet tissues, such as bags and boxes, but bag-like containers with opening/closing lids are convenient to carry and cost-effective. It is also inexpensive and easy to manufacture in terms of production technology.

The applicant of the present application previously disclosed in Japanese Utility Model Publication No. 59-2696 that a closed-loop perforation was provided on one side of a bag body, an opening/closing lid covered this perforation, one end of the opening/closing lid was fixed to the bag body, and the opening/closing lid was We have proposed a cosmetic enclosing bag in which a pressure-sensitive adhesive is applied to the inner surface of the bag, and the lid can be opened and closed repeatedly using the pressure-sensitive adhesive. This cosmetic enclosing bag is already widely used.

In addition, commercially available wet tissue packaging bags have a U-shaped perforation in the bag body instead of the closed loop, and have an opening/closing lid attached to the bag body (one end of the opening/closing lid is attached to the bag). (not attached to the body).

[The problem that the idea attempts to solve]

When purchasing this type of sealed bag product with a resealable lid, consumers want to be able to confirm that the product is being used for the first time, that is, that the product is not a used product. In order to satisfy such consumer desires, it is preferable to have a structure that does not return to its unused state once used.

In particular, if a textile material impregnated with cosmetics such as lotion or milky lotion is stored in an enclosure bag with a resealable lid, the cosmetics may be contaminated if the bag is opened and the contents are touched with dirty hands. Therefore, when purchasing a product containing cosmetics, it is desirable for consumers to be able to easily confirm from its appearance that the product is not a used product, that is, it has not been used.

Even in the above-mentioned known encapsulation bag, when the opening/closing lid is opened for the first time, the closed loop or the portion surrounded by the U-shaped perforation of the bag adheres to the opening/closing lid and is separated from the bag body. It has a sealing function that allows you to confirm that it is being used for the first time.

However, since the perforations are hidden in the opening/closing lid, unless you are very careful when opening the opening/closing lid, it is difficult to confirm whether or not the opening/closing lid is opened or not.

Furthermore, with conventional encapsulation bags with opening/closing lids, it is not possible to determine whether the bag is unused or not from the appearance, and this cannot be determined until the opening/closing lid is opened. Therefore, before purchasing an enclosed bag product, it is not possible to confirm that it is not a used product.

One idea is to put a sticker around the periphery of the open/close lid to easily determine whether it is unused from its appearance, but preparing the sticker separately would be expensive and would require a lot of time and effort. There is a problem that it takes Furthermore, it is also possible to intentionally and neatly peel off the sticker to take out the contents and then reapply the sticker as before, so it is impossible to reliably confirm whether or not the item is unused.

Japanese Utility Model Publication No. 57-98270 discloses that both ends of a band-shaped lid are fused to both ends of an enclosure bag, a break line is provided in a part of the band-shaped cover, and a handle is placed in the center of the break line. An encapsulation bag is disclosed that is provided with a bend for forming an encapsulation bag. It is possible to judge whether this sealed bag is unused or not by looking at the break line, but the band-shaped lid material is tightly attached to the surface of the bag with adhesive, and there is also a part that will become the handle. Since it is tightly attached to the surface of the bag at the center of the break line, it is extremely difficult to open the bag because there is no clue to cut the break line.

This invention allows you to easily check whether the enclosure bag is unused, makes it easy to open the lid for the first time, and allows you to easily open and close the lid repeatedly after use. The purpose of this product is to provide a cosmetic enclosing bag with

[Means to solve the problem]

According to the present invention, the above problems have been solved by a cosmetic bag having a sealing function, which comprises a bag body formed of an airtight sheet material having an opening on one side for removing the contents, and a lid material made of the sheet material and covering the opening, the lid material being composed of an opening/closing lid part which covers the opening of the bag body and is attached to the bag body so as to be repeatedly openable and closable, and a sealing part which is provided on the periphery of the lid material and fixed to the bag body, the opening/closing lid part having a pressure-sensitive adhesive layer on almost the entire inner surface which comes into contact with the bag body, the opening/closing lid part having a fixing part at one end which fixes the opening/closing lid part to the bag body, and a handle part at the other end which is not coated with pressure-sensitive adhesive, the handle part being located on the periphery of the lid material at a place separate from the sealing part, the sealing part being partially connected to the opening/closing lid part and being separated from the opening/closing lid part by a cutting slit.

[Effect]

The separation notch provided between the opening/closing lid and the sealing part is cut when the opening/closing lid is opened, and the opening/closing lid and the sealing part are separated, and the sealing part remains fixed to the bag body. .

Once the cutting notch is cut off, it does not return to its original state, so by checking whether the sealing part has been cut off, it is possible to confirm whether or not it is unused.

Furthermore, since the handle is provided on the periphery of the lid separately from the sealing part and is not coated with a pressure-sensitive adhesive, the handle is easy to pick and the lid can be opened easily.

[Explanation of Examples]

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a perspective view of an embodiment of the cosmetic enclosing bag of the present invention. The cosmetic enclosing bag of the present invention is made of an airtight sheet material and includes a flat bag body 1 having an opening 2 on one side for taking out the contents, and a lid material 30 made of a sheet material and covering the opening 2.

Furthermore, the lid member 30 includes the sealing portion 9 and the opening/closing lid portion 3.
A separation notch 12 is formed which connects only a portion of the two and separates the two, and this separation notch 12 may be a perforation-like cut, a chain line-shaped cut, or a cut that reaches near the bottom of the opening/closing lid. It can be done. The sealing part 9 can be separated from the opening/closing lid part 3 along the cutting cut 12.

FIG. 2 is a perspective view showing the open/close lid 3 of the cosmetic enclosing bag shown in FIG. 1 in an open state.

As shown in FIG. 2, an opening 2 is formed on one side of the bag 1 for taking out the stored contents (cosmetic material impregnated into a fiber material or foam) 5. The opening 2 is formed by punching out the sheet material of the bag, and has an appropriate shape such as a circle, an oval, a rhombus, or a track shape. A lid material 30 is attached to cover the opening 2.

The opening/closing lid part 3 has an area larger than the opening 2, and can have an appropriate shape such as a circle, an ellipse, a square, or a track shape. Furthermore, a pressure-sensitive adhesive is applied almost entirely to the surface (inner surface) of the opening/closing lid portion 3 that comes into contact with the bag body 1, thereby forming a pressure-sensitive adhesive layer 7. With this pressure sensitive adhesive 7, the opening/closing lid part 3 is attached to the bag body 1.
