JPS6033868Y2 - Container for viscous liquids with brushed lid - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container for viscous liquids having a lid with a brush and used for storing mascara liquid, nail polish liquid, etc.

As shown in FIG. 1, a conventional container of this type has a mouth portion 10a.
and a hole 12 provided in the mouth portion 10a.
an elastic membrane 14 having a
And, an extension hole 12 is attached to the inner surface of this lid 16 and inside the class 10.
It consists of a shaft 18 that slides into contact with the shaft, and a brush 20 attached to the tip of this shaft.

When using this container, if the brush 20 is inserted into the container 10, the contents 22 such as mascara liquid may overflow or scatter from the opening 10a, which may cause problems.

This is due to the following reason.

When the brush 20 is inserted into the casing 10 after applying the content 22 to a necessary location with the brush 20, the content remaining on the brush 20 adheres to the upper surface of the membrane 14.

When the brush 20 is removed from the bottle 10, the liquid content 22 that has been wiped off the shaft 18 by the membrane 14 adheres to the lower surface of the membrane 14 and remains there due to the viscosity of the liquid content.

Also, if the entire container is laid down before use,
Even if the bottle 10 is held upright, the liquid content remains attached to the lower surface of the membrane 14 due to its viscosity.

When the brush 20 is inserted into the class 10 in this state, the shaft 18
Since the air in the container 10 is compressed, this pressure causes air to adhere to the upper and lower surfaces of the membrane 14 through the gap between the hole 12 of the membrane 14 and the shaft 18 or the gap between the rim 10b of the bottle 10 and the membrane 14. The liquid content may overflow or scatter.

The present invention solves the above disadvantage by providing a hole in the shaft 18 to allow the compressed air inside the bottle to escape.

The present invention will be explained according to the embodiment shown in FIGS. 2 and 3.

50 is a bottle, and an elastic membrane 54 made of rubber or the like and having holes 52 is provided at the mouth 50a of the bottle.

A lid 56 is attached to the mouth 50a of the bottle 50.

A pipe 58 is attached to the inner surface of the lid 56 so as to slide into the extending hole 52 within the casing 50.

A brush 60 is attached to the tip of this pipe 58 by a holding pin 62 inside the pipe.

64 is an intermediate hole, which connects the brush 60 of the pipe 58 to type 5.
It is provided at a location located inside the casing 50 from the membrane 54 when inserted into the casing 50.

Reference numeral 66 denotes a root hole, which is provided near the attachment portion of the pipe 58 to the lid 56.

68 is a porous body made of urethane foam or the like, and is provided between the root hole 66 and the edge of the lid 560.

A partition plate 70 is provided between the porous body 68 and the edge of the lid 560, and has ventilation holes 72.

Therefore, in this container, as shown in FIG.
Since it flows out through the root hole 66, the porous body 68, and the ventilation hole 72, the compressed air causes the content liquid 74 to flow into the mouth part 50a.
There will be no overflow or splashing.

At this time, the content liquid may also flow out from the intermediate hole 64 along with the air, but this content liquid is absorbed by the porous body 68 and does not flow out.

Note that the vent hole 72 through which air flows out is formed in the partition plate 70, so when the lid 56 is completely closed, the vent hole 72 is blocked by the mouth portion 50a, and the liquid content 74 evaporates. It never dries out.

Since it is preferable that the amount of liquid flowing out from the intermediate hole 64 is small, the intermediate hole 64 is preferably located inside the membrane 54 and close to the membrane 54, that is, above the bottle 50 when it is stood upright.

This is because the bottle 50 is often used in an upright position, and the air is often located above.

Further, it is also effective to use a double layer as in another embodiment shown in FIG.

This example is a container similar to the previous example, with a membrane 5
4. Add a lower membrane 54' to the inside of the strand 50, which loosely slides on the pipe 58, and insert an intermediate hole 64 into the brush 60 of the pub 58.
It is provided at a location located between the membrane 54 and the lower membrane 54' when inserted into the casing 50.

Therefore, in this container, most of the liquid content is always in the lower membrane 54.
Since there is almost no liquid between the membrane 54 and the lower membrane 54', the amount of liquid flowing out from the intermediate hole 64 is small.

With the container of the present invention, the pressure inside the bottle does not increase and the liquid content does not overflow or scatter, so your hands and clothes will not get dirty during use.

For this reason, the present invention can be used to store various viscous liquids such as glue, hair dye, liquid lipstick, etc., but especially mascara, which is often placed horizontally and is small, so the pressure inside the bottle tends to increase. Suitable for storing liquids, nail polish remover, etc.
