Description

[Detailed Description of the Invention] The present invention relates to an easily portable applicator for applying liquid cosmetics, liquid medicines, etc.

2. Description of the Related Art Conventionally, there have been some simple portable applicators for liquid materials that have an integrated applicator function section and a content storage section.

These structures are characterized by the material of the partition plate interposed between the coating liquid storage section and the application section.

One is a type in which the partition plate receives stress when applying strong pressure to the coating liquid storage part, causing cracks and the coating liquid oozes out and transfers to the application part. It consists of an applicator and a partition that can be torn open from the applicator side using a sharp, hard rod.

However, when using these conventional applicators, when stress cracks occur, the former do not crack uniformly and the coating liquid does not transfer smoothly to the applied area, making it difficult. This type has problems in that it requires a sharp rod-breaking tool separately, and that the coating material is also damaged when the partition plate is broken from the coating section side.

The present invention was developed in view of these backgrounds, and its purpose is to make it possible to uniformly tear the partition plate between the coating solution storage section and the application section, and to allow the coating solution to seep out smoothly onto the coating body. An object of the present invention is to provide a portable applicator.

Another object of the present invention is to provide an applicator having a structure that does not damage the applicator when breaking the partition plate.

The present invention is characterized by an adhesive layer applied to a porous sheet, an impermeable sheet fixed to the adhesive layer, and a liquid and a protrusion extending from the container toward the impermeable sheet.

The main proposal will be explained below based on the drawings.

FIG. 1 is an overall view of the present invention, and FIG. 2 is a sectional view.

Container 1, which is a coating liquid storage body, is made of polyvinyl chloride, polypropylene, or polyethylene.

It is obtained by vacuum forming a sheet of polyamide resin or the like.

It is also possible to obtain the resin material by thin injection molding.

Preferably, a material with good transparency is used.

This makes it easier to check the movement of contents and the state of tearing of the impermeable sheet 2.

A protrusion 6 having a sharp tip is formed in the container 1 toward the inside of the container 1.

The shape of the protrusion 6 may be any shape, but a conical shape is preferable since the purpose is to break the impermeable sheet 2 interposed between the coating liquid storage section and the application section.

Further, the number of the protrusions is not limited to a single number, and a plurality of protrusions 6 may be formed as necessary.

Inside the container 1 formed in this manner is a fluid cosmetic liquid and makeup foundation.

Contains antiperspirant liquid, insect repellent liquid, polishing liquid cosmetics, medicines, paints, etc.

The container 1 is sealed by an impermeable sheet 2.

The impermeable sheet 2 is suitably an extremely thin synthetic resin film made of polyethylene, polypropylene, polyamide, etc., or a composite laminate of these films and aluminum foil.

This makes it possible to use a hot press method when fixing the container and the impermeable sheet 2.

Alternatively, aluminum foil may be coated with a resin liquid that can be bonded to the container.

Then, the container 1 and the impermeable sheet 2 are attached together by adhesion or self-adhesion using methods such as hot pressing or adhesive application.

A porous sheet 4 is formed as a coating portion on the impermeable sheet 2 side of a container fixed to the periphery of the impermeable sheet 2 with an adhesive layer 3 interposed therebetween.

These impermeable sheets 2 are formed so that they can be torn by projections 6 provided inside the container 1.

The porous sheet 4 is made of foamed polyurethane because it has a coating function and should be flexible, and because the coating liquid needs to ooze out evenly.

Various foams such as foamed rubber and foamed cellulose, and fiber materials such as cotton, woven fabric, non-woven fabric, and cardboard are suitable.

Furthermore, the coating effect can be increased by subjecting the surface of the porous sheet 4 to a surface treatment such as flocking or grain planting.

The impermeable sheet 2 and the porous sheet 4 are bonded together by an adhesive layer 3.

The adhesive layer is acrylic, olefin, polyamide,
Polyester-based, rubber-based, etc. are preferred, and either solvent type or emulsion type may be used.

To use the present invention configured as described above, first, the presser portion 5 of the container 1 is strongly pressed with a fingertip.

Since the holding part 5 is located at the root of the protrusion 6, by applying strong pressure, the protrusion 6 will move forward from its original position.

From this, the protrusion 6 penetrates and breaks the impermeable sheet 2 sealing the container 1.

After breaking, the protrusion 6 is restored to its original position.

Next, the contents pass through the torn portion and transfer to the porous sheet 4, making it ready for application.

Therefore, since the porous sheet 4 is torn from the inside, the contents can be smoothly oozed out without damaging the porous sheet 4.

Furthermore, since a plurality of the structures of the present invention can be connected in a detachable manner by a part of the porous body, different types of contents can be carried at the same time.

As described above, the present invention is a very convenient portable applicator that can reliably and uniformly transfer the contents from the container to the applicator without requiring any additional tools compared to conventional applicators of this type.
