2. Description of the Related Art Conventionally, a container containing a coating solution and having an opening, and a cap detachably attached to the opening of the container and having brush parts for applying the coating solution, are continuously provided via a shaft part. An applicator having a so-called pickled brush structure, which is composed of and, is known. The cap of this applicator consists of a lid part with an internal thread placed inside it so that it can be easily attached to and detached from the container, a shaft part that can be secured inside the female thread of the lid part, and a side opposite to the lid part of the shaft part. In addition, the brush component is formed by bundling and embedding the center of many long fibers with U-shaped wire or the like. The long fibers of the brush parts are made from various animal hairs, such as polyethylene terephthalate resin, polyamide resin, polybutylene terephthalate resin, or other animal hairs or synthetic resin fiber materials, so that they can be applied cleanly. Were mixed (mixed hair) and used.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to consume the built-in coating liquid as much as possible. Recently, like cosmetics manicure containers and adhesive containers, transparent applicators often use built-in manicure and adhesive liquids so that the color and remaining amount of them can be seen from the outside. In the case of such a transparent container, the larger the remaining amount of coating liquid that cannot be consumed, the more easily the amount of the remaining coating liquid can be seen from the external appearance, which is a waste of resources.
By the way, the cap of the above-mentioned conventional applicator is composed of a lid part, a shaft part, and a brush part. In these three parts, there are large variations in the length of each part and especially in the length of the brush parts due to long fibers, so it is necessary to lengthen the gap between the tip of the brush parts and the bottom surface of the container inner surface in consideration of these three parts variations. was there. Therefore, if this gap is long, there is a problem that the remaining amount of the coating liquid that cannot be consumed increases (see P in FIG. 1). By the way, when the tip of the brush part is brought into contact with the bottom surface of the inner surface of the container, the tip of the brush is deformed,
Since the application work becomes difficult, it was necessary to prevent the tip of the brush from coming into contact with the bottom surface of the inner surface of the container. Since the brush part is formed by binding a large number of long fibers together, variations in the shape and length of the brush part and the number of fibers occur, so that it is difficult to make it uniform. During the coating work, the entire brush parts embedded in the shaft part of the cap fall out, and the coating work becomes impossible,
Some of the long fibers that form the brush parts fall out,
There was a problem that the application work could not be done cleanly. As the number of parts increases, there is a problem that the manufacturing cost becomes expensive. Recently, in general households, when disposing of used products, most local governments have to separate and discard each material such as metal material, glass and synthetic resin material. In addition, when collecting a large amount of used products and reusing structural part materials, it is possible to sort and collect not only different materials such as metal, glass and synthetic resin for structural parts but also synthetic resin materials by type. There must be. However, when various materials and types of synthetic resin materials are mixed and used in structural parts, there is a problem that disassembling and separating for disposal and recycling is troublesome. The present invention makes it possible to consume the built-in coating liquid as much as possible, to make the shape and length of the brush parts and the number of fibers uniform, and to prevent the brush parts from falling off and some of the long fibers from falling out. It is an object of the present invention to provide an applicator capable of facilitating dismantling / separation of used products for disposal / recycling while keeping the manufacturing cost high.

[0004]

According to the present invention, there is provided a container containing a coating solution and having an opening, and a brush part which can be attached to and detached from the opening of the container and which applies the coating solution to the container via a shaft part. In the applicator including a continuously provided cap, the gist of the applicator is that the cap is formed by integrally forming a lid portion, a shaft portion, and a brush portion.

Further, for the purpose of improving heat resistance, cold resistance, impact resistance, etc., there are polymer alloy materials in which these various synthetic resin materials are mixed. Furthermore, recycled materials provided by companies that recycle synthetic resin materials can also be adopted. The container 1 is formed by injection blow molding using the same injection molding grade synthetic resin material as the cap 2. When the direct blow molding method is adopted as the molding method of the container 1, it is preferable to use a synthetic resin material of the same kind as the cap 2 of the extrusion molding grade.

In the first embodiment, the lid portion, the shaft portion and the brush portion constituting the cap are formed by one component integrally molded by the injection molding method, and the negative carved in the same mold. The shape is filled with synthetic resin and molded, and unlike the conventional product, it is not a combination of many parts. Therefore, the variation in the length from the inner part of the female screw of the lid portion to the tip of the brush portion can be reduced as compared with the conventional product. Furthermore, since the brush part is formed by engraving in the mold and is not formed by bundling a large number of long fibers like the conventional product, there is less variation in the brush part shape and length than the conventional product. it can. As the length variation can be reduced, as shown by the gap P in FIG. 1, the gap between the tip of the brush portion and the bottom surface of the inner surface of the container can be reduced, and the remaining amount of the coating liquid that cannot be consumed can be reduced. It is possible. Further, in the first embodiment, the brush portion is formed in a shape engraved in a mold and is not formed by binding a large number of long fibers unlike the conventional product. The shape, length, and number of fibers can be made uniform with little variation. In addition, in the first embodiment, the brush portion is integrally formed with the shaft portion in a shape engraved in a mold, and is formed by binding a large number of long fibers and embedding it in a shaft component like a conventional product. Therefore, it is possible to prevent the brush parts from falling off and the long fibers from partially falling off unlike the conventional products. Also, the first
In the embodiment, the lid portion, the shaft portion, and the brush portion that form the cap are formed by one component integrally molded by the injection molding method, and are not a combination of many components unlike the conventional product.
Cost of one part is cheaper than total cost of many parts,
Since the cost of assembling a large number of parts is also unnecessary, the manufacturing cost does not increase. Furthermore, in the first embodiment, the lid portion, the shaft portion, and the brush portion that form the cap are formed by one component integrally formed of the same synthetic resin material, and a large number of components are combined like a conventional product. Since it is not a combination of different synthetic resin materials and does not include a U-shaped wire, disassembling / separating is unnecessary. Further, since the container is formed by using the same synthetic resin material as the cap, the product can be reused as it is without disassembling / separating.
