Abstract

A liquid cosmetic container wherein the operation portion is provided on side surface of the container body 1 . When the operation portion is pressed from the outside, the valve body 5 seating on the valve seat portion 6 a is moved in the axial direction by the valve pressing portion 6 h and seats away from the valve seat portion 6 a , so that the flow path, in which the liquid cosmetic flows, is opened and then, the liquid cosmetic is supplied to the application body 4 . Thus, it is not necessary to push the application body into the container 1 . Further, the opening/closing of the flow path are performed by moving the valve body 5 in the axial direction by pressing the operation portions from the outside, so that the diameter of the container body 1 can be reduced, comparing with the conventional container.

First claim

What is claimed is:

1. A liquid cosmetic container comprising:
a container body comprising a storage portion adapted to store a liquid cosmetic;
an application body provided at a top end of the container body and adapted to allow application of liquid cosmetic;
a flow path connecting the application body and the storage portion of the container body, and adapted to allow liquid cosmetic to flow from the storage portion to the application body;
an operation portion provided on the side surface of the container body and configured to be pressed from the outside;
a valve seat member having a valve seat portion with an opening provided in the container body;
a valve body provided movably in the axial direction in the container body, and provided with an enlarged diameter portion, wherein said valve body is biased to close the flow path by seating on the valve seat portion, and open the flow path by moving away from the valve seat portion; and
a valve body pressing portion making the valve body to move in the axial direction so as to be away from the valve seat portion by which the enlarged diameter portion is pressed from the outside; wherein by pressing the operation portion from the outside, the valve body pressing portion moves the enlarged diameter portion toward said application body to a side of the valve seat portion, so that the valve body is moved away form the valve seat portion.

2. The liquid cosmetic container according to claim 1 ,
wherein the valve body includes a bar-shaped member formed in a round bar shape extending in the axial direction, the enlarged diameter portion, which is integrated with a back end portion of the bar-shaped member and has a diameter larger than the bar-shaped member, and
the valve body further includes a head portion on the front side thereof with a larger diameter than the bar-shaped member.

3. The liquid cosmetic container according to claim 2 , wherein said opening in the container body is at the axial back end of said valve seat member, wherein an enlarged diameter hole portion is formed on the more front side of said opening with a hole more enlarged than the opening, and
the head portion enters said enlarged diameter hold portion and is urged backward against the front side of the opening of the valve seat portion.

4. The liquid cosmetic container according to claim 1 ,
wherein the operation portion is made of an elastic material.

5. The liquid cosmetic container according to claim 1 ,
wherein container body and the operation portion are integrally molded by two-color molding.

6. The liquid cosmetic container according to claim 1 ,
wherein the enlarged diameter portion is a taper portion including in the axial direction and being moved in the axial direction by pressing the operation portion.

7. The liquid cosmetic container according to claim 6 ,
wherein the taper portion has a truncated cone shape, including in the axial direction,
wherein a contact surface of the valve body pressing portion to the valve body is a taper surface having the same inclination as the taper portion of the valve body.

8. The liquid cosmetic container according to claim 1 ,
wherein an elastic member is provided in the container body; and
a front end of the elastic member is fixed and supported by a spring support portion at the back side of the valve seat portion, and a back end of the elastic member is fixed and supported by the front end of the enlarged diameter portion so that the valve body is urged in the direction as so to be sealed on the seat portion by the elastic member.
