Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a cosmetic enclosing bag, and in particular to a simple container for packaging a plurality of fiber materials impregnated with cosmetic liquid, etc. Regarding bags.

[Description of the Prior Art] In recent years, disposable napkin products in which fibrous materials such as nonwoven fabrics are impregnated with liquid cosmetics have come into widespread use.

There are many types of storage containers for disposable napkins, such as bags and boxes.

Most of these storage containers are made of synthetic resin injection molded or vacuum molded products and are bulky, making them inconvenient to carry.

Furthermore, there are various types of cosmetics that can be impregnated into fiber materials (for example, disposable napkins, cut cotton for cosmetics, etc.) depending on the intended use of the fiber material, such as removing stains or removing makeup.

Although there are many types of cosmetic containers, a bag-shaped container with an opening/closing lid is considered to be inexpensive and easy to manufacture in terms of production technology.

Conventionally known bags of this type have an opening (take-out port) formed on one side of the bag, a lid member covers this opening, one end of the lid member is fixed to the bag, and the lid There is a cosmetic packaging bag in which a pressure-sensitive adhesive is applied to the inner surface of the member, and the lid member can be opened and closed repeatedly using this pressure-sensitive adhesive.
(Refer to Utility Model Application Publication No. 4947018).

However, in the above-mentioned bag, since the take-out port is opened, when the lid member is closed and sealed, the contents stored in the bag body and the pressure-sensitive adhesive of the lid member are exposed to the take-out port ( The adhesive itself may adhere to the contents, or the odor of the adhesive may transfer to the contents, causing deterioration or odor to the contents. There is a problem with putting it away.

In view of the above-mentioned problem of deterioration of the contents and odor associated with the conventional cosmetic enclosing bag, the inventor of the present invention created an opening with an opening in order to eliminate the adverse effects caused by direct contact between the adhesive and the cosmetic. An attempt was made to apply a pressure-sensitive adhesive layer to the lid member except for the parts corresponding to It is necessary to sufficiently improve the positional accuracy, making management of these manufacturing conditions cumbersome or difficult, and the manufacturing cost is high, making it impossible to put it into practical use.

In addition, for this type of bag-shaped product with an opening/closing lid, we hope that consumers will be able to confirm that the product is being used for the first time at the time of sale, that is, that the product is not a used product. In order to satisfy this desire, it is preferable to have a structure that does not return to its unused state once it is used.

[Purpose of the invention]

The present invention has been made in view of the problems of the prior art as described above, and
This design was made in consideration of the various characteristics required of a cosmetic enclosing bag.

That is, an object of the present invention is to provide an enclosed bag that does not allow the adhesive itself in the opening/closing lid part or the odor of the adhesive to transfer to the contents and affect the contents, and which can be continuously produced. With the goal.

In addition to the above-mentioned object, the present invention provides a cosmetic enclosing bag that can store two types of cosmetics depending on the purpose of use without interfering with each other, even though it is a single bag body. The purpose is also to

The present invention provides a flat bag made of an airtight sheet material, in which the interior of the bag is divided into two storage sections by a shielding sheet, and each storage section has an opening for taking out the contents. Only the opening of one storage section is substantially closed by a closing seal, and is further covered by a lid member, which covers the outer surface of the bag body and the side in contact with the closing seal. The lid member has a pressure-sensitive adhesive layer on almost the entire surface, and the opening can be repeatedly opened and sealed together with a closure seal attached to the lid member, and the other storage compartment can hold dry contents. The above-mentioned purpose is achieved by a cosmetic enclosing bag which is for storing cosmetics and has no lid member at its opening.

Furthermore, as shown in the embodiments of the present invention, the cosmetic-containing bag of the present invention is provided with a sealing function, so that the cosmetic-containing bag can be used for the first time by a consumer, so that the consumer can be assured that the bag will be used for the first time. can be provided.

That is, as shown in one embodiment of the present invention, the closure seal is a sheet piece torn from the bag body, and the structure where the sheet piece is torn off becomes the opening in the bag body. This allows consumers to feel confident that they are using the product for the first time when they use it for the first time.

In addition, as shown in other embodiments, the closing seal is made separate from the bag, is slightly larger than the opening of the bag, and has a shape that is almost similar to the opening, and the closing seal is attached to the bag in advance. By placing it in a position that substantially covers the internal opening,
When the lid member is opened from the bag body for the first time, the closing seal is attached to the bag body by the pressure-sensitive adhesive layer and does not return to the inside of the bag body again, so that the consumer can be assured that he/she is using it for the first time. Is possible.

For other storage compartments, perforations etc. are engraved on the bag body to form the opening (take-out port), and the perforations are torn off when used for the first time. It is possible to help consumers gain confidence when using the product for the first time.

As a method for rationally manufacturing the cosmetic enclosing bag having two storage sections according to the present invention, three sheet materials may be polymerized and then bag-made.

In this way, the inner sheet (middle sheet) becomes the shielding sheet portion.

[Explanation of Examples]

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments of the present invention.

[Description of configurations common to the illustrated embodiments] FIG. 1 is an overall view of an embodiment of the cosmetic enclosing bag of the present invention, with a portion cut away to show the inside of the bag.

The cosmetic enclosing bag of the present invention is a flat bag 1 made of an airtight sheet material, and has a shielding sheet 8 provided so as to partially cover the inside of the bag 1.

That is, since the shielding sheet 8 is provided in the middle of the sheets forming the bag body 1, the cosmetic enclosing bag of the present invention has two storage parts although it is a single bag body 1. It is possible to store two different types of contents.

One side of the bag body 1 is provided with an opening 2 in the shape of a circle, an oval, a diamond, a track, etc., in order to take out the contents stored in one storage part, and a closure that substantially covers the opening 2. A seal 5 and a lid member 4 are provided.

The lid member 4 is fixed to the bag body 1 at one end 3, and a pressure-sensitive adhesive layer 6 is formed on almost the entire surface of the side that contacts the bag body 1 (hereinafter referred to as the inner surface).

After the cosmetic bag is used for the first time, the closure seal 5 is attached to the pressure-sensitive adhesive layer 6 on the inner surface of the lid member 4, as shown in FIG.

This closing seal 5 substantially covers the opening 2 when the lid member 4 is closed, and the lid member 4 is attached to the bag body 1 by a pressure-sensitive adhesive layer 6 around the closing seal 5. Then, the opening 2 of the bag 1 is sealed.

In this way, in the cosmetic enclosing bag of the present invention, the lid member 4
Since the closing seal 5 affixed to the bag covers the opening 2, the cosmetic stored inside the bag 1 does not come into direct contact with the pressure-sensitive adhesive layer 6 even in the sealed state, and the cosmetic remains clean. is maintained.

The aforementioned storage compartment with a lid member can be sealed, so it is suitable for storing moisture-containing textile materials such as wet napkins. Therefore, there is no need to provide an opening/closing lid structure.

Therefore, the other storage section mainly stores dry contents and is not provided with a lid member.

That is, the other side of the bag 1 (in FIG. 1, it is the lower side and cannot be seen).

2 and 4) is provided with an opening 2 for taking out the contents stored in the other storage section, but is not provided with a lid member.

The opening 2 is formed by linear, thin rectangular, structured circular, etc. cuts or perforations in the sheet material constituting the bag 1, and the consumer can tear the perforation 9 to create an outlet. Become.

The airtight bag 1 can be formed from the following sheets.

The main materials include synthetic resins such as polyethylene, polypropylene, polyester, polyvinyl chloride, polyamide, cellophane, and acetate, single films, laminations of films, and composite materials.

Furthermore, depending on the type of contents, the various films mentioned above,
A composite material laminated with aluminum foil can be used.

Next, regarding the shielding sheet 8 that forms part of the bag body 1, it is either a film made of the same material as the film forming the bag body 1, or a film that has hot-melt properties and is heated at a lower temperature than the bag body 1 on both sides of these films. Those coated with a melting adhesive are good in terms of airtightness.

The material of the lid member 4 may be the same as that used for the bag body 1.

As for the shape of the lid member 4, it is of course preferable that the area of the lid member 4 is larger than the opening 2, and that its shape is circular, oval, square, track-shaped, etc.

The pressure-sensitive adhesive layer 6 provided on the inner surface of the lid member 4 is preferably made of acrylic, rubber, polyester, polyolefin, resin, etc., and the coating method thereof is roll coating, roll coating, etc.
It is preferable to use a method such as knife coating or spray coating.

Note that if the lid member 4 is made of a transparent sheet material, the contents and the state of the opening 2 can be clearly seen from the outside.

Further, a protruding handle portion 7 is provided at the end of the lid member 4 opposite to the fixed end portion 3.

Preferably, the pressure-sensitive adhesive layer 6 is not applied to this handle portion 7, as shown in the drawings.

As a method of fixing the lid member 4 and the bag body 1, any method such as ultrasonic bonding, high frequency bonding, heat bonding, adhesive bonding method, etc. can be used, and the method is appropriately selected depending on the material of the bag body 1.

Further, on the other surface of the bag body 1, linear, thin rectangular, or structured circular cuts and perforations are formed by press working.

Regarding the bag manufacturing method, it is easy to manufacture the bag from three sheet materials, which are two sheet materials constituting the bag body 1 and a shielding sheet 8 sandwiched between them.

In this case, after the contents are placed on a sheet in the same way as in normal bag making, the outer periphery of the bag is fixed. can be adopted.

[Description of Specific Example 1] Next, based on FIGS. 2 and 3, an embodiment in which the closing seal 5 in FIG. 1 is formed by a sheet piece cut off from a part of the bag body 1 will be explained. explain.

A closed-loop perforation 9 is provided on one side of the bag 1 in the shape of a circle, oval, square, diamond, or track, corresponding to the storage part to which the lid member 4 is attached. The lid member 4 is attached so as to cover 9.

In this embodiment, the configurations of the bag body 1, closure seal 5, and lid member 4 are the same as those described based on FIG. 1.

When using this enclosure bag for the first time, as shown in FIG. 3, first grasp the handle 7 of the lid member 4 fixed to the bag body 1 with your fingertips to open the lid member 4.

At this time, the sheet constituting the bag body 1 is torn along the closed loop perforation 9 provided in the bag body 1, and this torn sheet piece is attached to the pressure-sensitive adhesive layer provided on the inner surface of the lid member 4. It is attached to 6.

A sheet piece separated from the bag body 1 along the perforation 9 of this closed loop becomes the closure seal 5.

Then, the cut-off mark of the closed loop perforation 9 left on the bag body 1 becomes the opening 2.

After taking out the contents from the opening 2, if the lid member 4 is returned to its original position on the bag 1, the bag 1 will have the same airtightness as the original, and can be used repeatedly from now on.

At this time, the closing seal 5, which is a sheet piece of the bag body 1 separated from the perforation 9 of the closed loop, remains attached to the lid member 4 and closes the opening 2, so it is pressure sensitive. The adhesive of the adhesive layer 6 does not come into direct contact with the contents.

Therefore, in the cosmetic enclosing bag of the present invention, the contents do not change in quality or change in odor.

In addition, since the user can confirm that the sheet piece of the bag 1 is separated from the perforation 9 at the time of first use, the user can obtain proof that the bag is being used for the first time.

Moreover, since the two types of cosmetics stored in the bag body 1 can be protected separately by the shielding sheet 8, completely different items can be stored.

For example, wet tissue paper is stored in a storage section with an opening/closing lid, and dry tissue paper is stored in the other storage section with only an opening 2.

Another method of use is to store multiple sheets of nonwoven fabric impregnated with cleansing lotion in the storage compartment with an opening/closing lid, and store multiple sheets of cotton in the other storage compartment with only the opening 2. You may.

By doing this, even though it is a single package,
Two types (so-called 2-way) can be used.

[Description of Specific Example 2] Next, another aspect of the closure seal 5 shown in FIG. 1 will be described based on FIGS. 4 and 5.

The bag 1 and the shielding sheet 8 within the bag 1 are made of the same materials as described in connection with FIG.

An opening 2 in the shape of a circle, oval, square, rhombus, track, etc. is formed on one side of the bag body 1 made of the above-mentioned material by punching with a press blade.

Furthermore, a closing seal 5 having a similar shape to the opening 2 and larger than the opening 2 is prepared, and when manufacturing the enclosure bag,
This closing seal 5 is provided so as to close the opening 2 from inside the bag 1.

Furthermore, a lid member 4 is attached so as to cover the opening 2 from the outside of the bag 1.
Paste.

Therefore, the closure seal 5 is attached to the lid member 4 through the opening 2.

The material of the closing seal 5 used here is preferably a relatively flexible synthetic resin film such as polyethylene, polypropylene, polyamide, polyvinyl chloride, or the like.

Note that the lid member 4 is made of the same material and in the same form as that described based on FIG. There is.

Further, the opening 2 on the other side of the bag 1 exists simply as an opening 2, and is exactly the same as described with respect to FIG. 1 above.

When using the enclosure bag formed in this way, first, the handle 7 located on the opposite side of the fixed end 3 of the lid member 4 fixed to the bag body 1 by the fixed end 3 is removed. Open the lid member 4 by pinching it with your fingertips.

At this time, the closing seal 5 provided on the inner surface of the bag 1 passes through the opening 2 of the bag 1, moves from the inside of the bag 1 to the outside, and is attached to the pressure-sensitive adhesive layer 6 of the lid member 4. It will be in a state where it is worn.

This phenomenon only occurs when the cosmetics enclosing bag is used for the first time, and when used thereafter, the closing seal 5 attached to the lid member 4 will remain in the same state and return to its original position. I will never go back.

Therefore, once the lid member 4 is opened, the closing seal 5 does not remain inside the bag, and the closing seal 5 closes the opening 2 from the outside of the bag body 1, which is one of the objects of the present invention. A reduction function is achieved.

Further, the closing seal 5 has a larger area than the opening 2,
A closing seal 5 is placed on a portion of the pressure sensitive adhesive layer 6 corresponding to the opening 2.
is completely adhered, so that the pressure sensitive adhesive layer 6 is completely attached to the opening 2.
There is no direct contact with the contents through the container, and the contents are stable in terms of quality.

Furthermore, as in the embodiment shown in FIG. 2, the shielding sheet 8 that partially covers the bag body 1 forms two storage areas in a single package, making it possible to store two types of products. can.

Furthermore, in the embodiments shown in FIGS. 1 to 5, the bag is entirely made of film-like material, and the two compartments are overlapped, so the finished product is It is flexible and has no unnecessary space, making it a rational storage body.

The cosmetic enclosing bag of the present invention is extremely convenient to carry, and can be produced continuously, which is extremely advantageous economically.
