DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with an applicator for a viscous liquid, and more particularly to a paint container with a stationery brush,
The present invention relates to a container with a viscous liquid applicator, such as a container with a cosmetic viscous liquid brush and a poster color container with a brush.

[0002]

2. Description of the Related Art A container with a viscous liquid applicator as described above, especially a container using a liquid cosmetic (viscous liquid type), has the problem that the liquid adheres to the shaft of the conventional applicator and stains the mouth of the container. was there. For this reason, for example, a conventional liquid cosmetic container such as mascara is usually provided with a wiping member, i.e., a squeeze packing film body, and the wiping member removes excess liquid attached to the application brush. Is usually there. However, in the case of the structure provided with the wiping member, the cosmetic adheres to the inner wall of the wiping member when the applying brush is pulled out, or when the applying brush is inserted into the container. Unused cosmetics remaining on the brush are removed around the through-hole of the wiping member, and a liquid pool remains at the bottom of the wiping member. The liquid pool adheres to the shaft and drops during use. There was a fear.

In order to solve such a problem, Japanese Utility Model Publication No. 59-39937 discloses that, when a shaft is inserted into a container body, an inner diameter of the wiping member is set on a shaft corresponding to a lower position of the wiping member. There has been proposed a liquid cosmetic container provided with a coating portion having a swollen portion having substantially the same diameter. In this container, when the application portion is inserted into the container body, the swelling portion completely removes the cosmetics adhered to the inner peripheral wall of the wiping member and the liquid pool remaining at the bottom of the wiping member. , It is possible to prevent the cosmetic from adhering to the shaft.

[0004] The above-mentioned bulging portion has made it possible to prevent the cosmetic from adhering to the shaft, but this structure has another disadvantage. That is, at the same time as the liquid is pushed into the container by the swelling portion, the air under the swelling portion is also pushed into the container, so that the internal pressure inside the container is increased. And there is a new problem that the cap screw is not easily set. In other words, the air and liquid on the upper part of the squeezing packing film body are pushed into the container like a pump, so that the internal pressure rises, and this internal pressure mainly acts on the bulging part, and as a result, the cap is pushed back against the force for closing the cap. In order to close the screw, the cap must be turned while consciously pushing it, giving the user a sense of discomfort. The internal pressure also increases when the applicator and its shaft are pushed into the container body. With the exception of special medical containers, there is no other way than turning the screw cap while pushing.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a container with a viscous liquid applicator according to the present invention will be described below with reference to the accompanying drawings. The container 10 includes a container body 12
And a cap 16 to which the applicator 14 is attached. At the mouth of the container body 12, a packing body 18 formed by integrally molding an elastic material such as rubber is provided, and the packing body 18 is a cylindrical portion fitted to the mouth of the container body 12. 20 and a squeegee packing film body 22 provided thereunder. This squid packing film 22
Has an inner diameter edge portion 28 in which a through hole 24 having an inner diameter slightly smaller than the diameter of the shaft 26 of the applicator 14 is formed, and the inner diameter edge portion 28 is attached to the shaft 26 of the applicator 14. This is for wiping the viscous liquid that has been removed and also for wiping excess viscous liquid that has adhered to the applicator 14. Above the squeeze packing film body 22 of the packing body 18, an enlarged diameter space portion 30 and a reduced diameter space portion 32 are provided in order from the bottom. Therefore, the cylindrical portion 20 of the packing body 18 includes the first inner peripheral wall 34 that defines the enlarged diameter space 30 and the reduced diameter space 32.
Is defined.

On the other hand, the upper part of the shaft 26 of the applicator 14 is provided with first and second annular projections 40 and 42 from below at intervals vertically. These first
The second annular convex portions 40 and 42 preferably have an outer shape like an abacus ball. The first annular convex portion 40 is for pushing the viscous liquid collected on the central upper surface of the stiffener packing film body 22 into the inside of the container main body 12, and therefore has an inner diameter of the through hole 24 of the stiffener packing film body 22. It has a larger outer diameter. On the other hand, for the purpose to be described later, the first annular convex portion 40 has a first inner peripheral wall 3 having a periphery thereof defining the enlarged-diameter space portion 30.
