Description

[Detailed Description of the Invention] The present invention relates to a container for storing mascara liquid, eyeliner liquid, etc., which has an applicator brush attached to the lid.

As this type of container, the one shown in FIG. 1 is known.

This container 10 is constructed as follows.

A rubber cylindrical body 14 is tightly fitted into the mouth 12a of the bottle 12, and a rubber membrane 18 having a hole 16 in the center is provided at the lower end of the cylindrical body 14.

A shaft 24 having a brush 22 at its tip is attached to the inner bottom surface of the lid 20, and this shaft 24 slides into the hole 16.

A convex thick portion 26 is formed on the outer periphery of this shaft 24, and the cylindrical body 14
Slides into contact with the inner circumference.

Therefore, when the brush 22 is inserted into the bottle 12, the thick part 2
6 pushes the content liquid adhering to the inner surface of the cylindrical body 14 and the upper surface of the membrane body 18 into the bottle 12, so that when the brush 22 is extracted,
After the content liquid adhering to the outer periphery of the shaft 24 is wiped off by the membrane 18, the content liquid on the upper surface of the membrane 18 is prevented from adhering to the outer periphery of the shaft 24.

In order to obtain the above actions and effects with this container, it is necessary to
The outer diameter of the cylindrical body 14 must be slightly larger than the inner diameter of the cylindrical body 14.

However, since the cylindrical body is generally small in size, it is difficult to reliably satisfy the above conditions using normal manufacturing methods. This results in a large number of defective products in which the thick portion 26 cannot pass through the cylindrical body 14.

The present invention provides a void on the outer surface of the cylindrical body to allow large deformation of the cylindrical body, thereby relaxing the above-mentioned dimensional conditions and preventing the occurrence of defective products.

The present invention will be explained according to the embodiments shown in the figures.

FIG. 1 shows a first embodiment of the present invention, and this container 30 is constructed as follows.

A cylindrical body 34 made of a flexible material such as rubber is provided in the mouth 32a of the bottle 32, and a membrane 38 made of a flexible material that protrudes inward and has a hole 36 in the center is provided at the lower end of the cylindrical body 34. It is provided.

A gap 40 is provided outside the cylindrical body 34.

A shaft 44 extending into the bottle 32 and slidingly contacting the hole 36 is attached to the inner bottom surface of the lid 42 that is attached to the mouth portion 32a, and a convex thick portion 46 that slidingly contacts the inner surface of the cylindrical body 34 is attached to the outer periphery of the shaft 44. is provided.

A brush 48 is attached to the tip of the shaft 44.

Therefore, in this container 30, the cylindrical body 34 has a gap 40 on its outer surface, so that it can be inflated to a large extent. Of course, even large swords can slide smoothly on the inner surface of the cylindrical body.

FIG. 3 shows a second embodiment, and in this container 50, a membrane body 5
2 protrudes inward from the intermediate portion of the cylindrical body 54.

In this way, as shown in FIG. 4, even when the large portion 56 passes through the membrane body 52, the membrane body 52 and the cylindrical body 5
This is convenient because the number 4 swells.

If the outer part of the membrane 64 of the cylindrical body 62 is made sufficiently thin, as in the container 60 of the third embodiment shown in FIG. Even without providing a void on the outer surface, the same effects as in the second embodiment can be obtained.

As described above, since the container of the present invention does not require strict dimensional conditions, it can be easily manufactured without producing defective products.

Therefore, the present invention is suitable for use in containers for mascara liquid, eyeliner liquid, nail polish liquid, etc., which are small and must be produced in large quantities.
