Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container with an antibacterial brush shaft made of a synthetic resin, which is suitable for use in a mascara container or the like and can prevent the invasion, generation and multiplication of bacteria.

[0002]

[Prior Art]

 In general, a container for storing foods, cosmetics, etc. is required to have a structure that protects the foods and cosmetics filled in the container from bacteria in view of hygiene. Among cosmetics, eye shadows, mascaras, eye lines and other eye products are used very close to the eyeballs, so it is desirable for hygiene to have a structure that can prevent bacterial invasion, generation and proliferation. .. For this reason, the containers used for these are subjected to sufficient sterilization treatment with ethylene oxide gas (EOG) or the like before the cosmetics are filled.

[0003]

[Problems to be solved by the device]

 However, since the above sterilization treatment only prevents the aseptic condition of the container before filling the contents, there is no possibility of bacterial invasion and subsequent growth after filling the contents or during use. Could not deal with. Therefore, in the container for storing the eye product, it is possible to realize a container having a structure that can effectively cope with the invasion of bacteria and the subsequent proliferation after filling the contents or at the time of use. Has been requested.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a container with an antibacterial brush shaft capable of preventing the generation and growth of bacteria.

[0005]

[Means for Solving the Problems]

 Therefore, the container with an antibacterial brush shaft of the present invention is a zeolite-based container that is at least the part of the synthetic resin forming the shaft part and the brush part that is hung on the back surface of the lid body and that is immersed in the coating liquid inside the container body. Alternatively, an apatite-based silver ion antibacterial agent is blended to solve the above problems.

[0006]

[Action]

 In the container with the antibacterial brush shaft of the present invention, the brush part and the shaft part are soaked in the coating liquid inside the container body that they are combined with the synthetic resin forming the brush part and the shaft part. The silver ions carried by the existing zeolite or apatite exert a bactericidal action on the coating solution. As a result, bacteria that have entered through the mouth of the container and sterilized substances that are present in the coating liquid are killed. In this way, the antibacterial action from the brush portion and part of the shaft portion is permanently exerted on the coating liquid, and the generation and growth of bacteria inside the container is prevented.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, a container with an antibacterial brush shaft of the present embodiment has a bottomed cylindrical container body 1 for containing the coating liquid A therein, and a mouth portion 2 of the container body 1. It is composed of a lid 3 which is detachably mounted, a shaft portion 4 which is vertically provided on the back surface of the lid body 3, and a brush portion 5 which is attached to the tip of the shaft portion 4. In such a container with a brush shaft, the brush portion 5 and the shaft portion 4 are inserted into the container body 1 from the insertion opening 6 formed in the mouth portion 2 of the container body 1, and the lid body 3 is attached to the mouth portion 2. In this state, the brush portion 5 at the tip of the shaft portion 4 reaches the vicinity of the bottom portion of the container body 1, and the brush portion 5 and the tip half of the shaft portion 4 are immersed in the coating liquid A.

Further, in the above-mentioned brush shaft-equipped container, an annular groove 7 is recessed on the back surface of the mouth portion 2 of the container body 1, and the lid body 3 is removed from the mouth portion 2 inside the annular groove 7 to make the brush shaft. A ring-shaped wiping member 8 for vertically wiping the excess coating liquid adhering to the shaft portion 4 and the brush portion 5 when the liquid is withdrawn from the container body 1 is incorporated so as to be vertically movable.

Examples of the resin forming the container with the brush shaft include polyethylene (PE), polypropylene (PP), polyamide (PA), polystyrene (PS), polycarbonate (PC), polyethylene terephthalate (PET), Acrylonitryl styrene (SAN) and the like are preferably used.

In such a brush shaft-equipped container, the shaft portion 4 and the brush portion 5 are formed of a synthetic resin containing a silver ion antibacterial agent. Antibacterial zeolite or antibacterial apatite is used as the silver ion antibacterial agent to be mixed with the synthetic resin as the base resin. The former antibacterial zeolite has a particle size of about 0.7 to 1.5 microns and is obtained by ion-exchange of sodium ions in the crystal structure of zeolite with silver ions having an antibacterial effect. The exchange rate of this silver ion is said to be 0.5 to 5%. Further, the compounding ratio of the antibacterial zeolite is set to 0.1 to 30% by weight with respect to the base resin. In addition, a silver ion antibacterial agent may be mixed in the entire shaft portion 4 and the brush portion 5 in order to simplify the mixing process. By incorporating a silver ion antibacterial agent into the brush portion 5, the purpose of exerting an antibacterial action on the coating liquid A can be achieved.

In the container with the brush shaft of the present embodiment, the brush part 5 and the shaft part 4 are inserted into the container body 1 from the insertion opening 6 of the mouth part 2 of the container body 1 when not in use or when carried. At the same time, the lid body 3 is attached to the mouth portion 2 of the container body 1, and when in use, the lid body 3 is removed from the mouth portion 2 of the container body 1 and the shaft portion 4 and The brush part 5 is taken out from the inside of the container body 1 and used.

However, according to the brush shaft container of this embodiment, since the synthetic resin forming the shaft portion 4 and the brush portion 5 is mixed with the zeolite-based or apatite-based silver ion antibacterial agent, That is, while the lid 3 is attached to the mouth 2 of the container 1 and the shaft 4 and the brush 5 are immersed in the coating solution A in the container 1, silver ions carried by the zeolite or apatite are It exerts a bactericidal effect on bacteria existing in the container body 1 and the coating solution A. Therefore, it is possible to almost kill the bacteria that enter the inside from the insertion opening 6 of the mouth portion 2 together with the shaft portion 4 and the brush portion 5 or with the coating liquid A attached to the brush portion 5, and the proliferation of the bacteria. Can be prevented.

If the wiping member 8 around the insertion opening 6 of the mouth 3 or the back of the mouth 3 is made of synthetic resin and the synthetic resin is mixed with a zeolite-based or apatite-based silver ion antibacterial agent, after use, When the brush part 5 and the shaft part 4 are returned from the insertion opening 6 to the inside of the container body 1, a bactericidal action is exerted on the coating liquid A attached to the brush part 5 and the shaft part 4 or the brush part 5, so that bacteria Can be effectively prevented.

As described above, since it is possible to effectively kill the bacteria that enter the container and to prevent the generation and growth of the bacteria in the coating liquid A, cosmetics, particularly eye products such as maska. Very suitable for

[0016]

[Effect of the device]

 As described above, according to the container with a brush shaft of the present invention, a sterilizing action is exerted on the coating liquid while the brush portion and a part of the shaft portion are immersed in the coating liquid inside the container body. As a result, it is possible to effectively kill the bacteria that have invaded through the mouth and the bacteria that are present in the coating liquid, and also to prevent the generation and growth of the bacteria inside the container. Therefore, the container with the brush shaft of the present invention can be suitably used for cosmetics such as eye products.
