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:
an elongated 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 an elongated side surface of the container body and configured to be pressed from the outside of the elongated container body
a valve seat member with a valve seat portion provided in the flow path of the container body;
a valve body adapted to be moveable in an axial direction in the valve seat member in the container body, and having 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 adapted to make the valve body move in the axial direction so as to be away from the valve seat portion when the operation portion is pressed from the outside, wherein
the valve body includes a front side shaft portion entering an opening portion of the valve seat portion, and a back side shaft portion formed in a substantially cylindrical shape and extending in an axial direction, and
a hole portion provided in a spring supporting portion of the valve seat member, in which the back side shaft portion is inserted.

2. The liquid cosmetic container according to claim 1 ,
wherein the valve body
configured with a core portion with a taper portion as said enlarged diameter portion provided between said front side shaft portion and said back side shaft portion;
wherein pressing the operation portion from the outside, the valve body pressing portion moves the enlarged diameter portion in the direction departing from the valve seat portion, so that the valve body is moved away from the valve seat portion.

3. The liquid cosmetic container according to claim 2 ,
wherein a spring member is provided in the container body and a front end of said spring member is fixed and supported at the back end of the taper portion and another end thereof is fixed and supported at the spring supporting portion of the valve seat member
such that the valve body is urged in the direction so as to be seated on the valve seat portion by said spring member.

4. The liquid cosmetic container according to claim 2 ,
wherein said valve seat member is provided with at a back end surface of the valve seat portion with arm members extending to a space in the back side in the axial direction; and
at the back end of the arm members said valve body pressing portions are provided.

5. The liquid cosmetic container according to claim 2 or 4 ,
wherein the taper portion inclines in the axial direction and being moved in the axial direction by pressing the operation portion.

6. The liquid cosmetic container according to claim 5 ,
wherein the taper portion has a truncated cone shape, inclining in the axial direction, and
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.

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

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

9. A liquid cosmetic container comprising:
An elongated container body comprising a storage portion at a first end thereof and adapted to store a liquid cosmetic;
an application body provided at a second end of the container body and adapted to apply 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 a side surface of the container body and configured to be pressed from the outside of the container body;
a valve seat member with a valve seat portion provided in the flow path in the container body;
a valve body adapted to move in an axial direction in the flow path in the container body, and provided with an enlarged diameter portion with a taper portion so as to make the diameter to gradually expand as going from the front end to the backside, 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 the valve body 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 pressing the operation portion from the outside, wherein
the valve body includes a front side shaft portion entering an opening portion of the valve seat portion, and a back side shaft portion formed in a substantially cylindrical shape and extending in an axial direction,
said taper portion is formed between the front side shat portion and the back side shaft portion,
a hole portion is provided in a spring supporting portion of the valve seat member, in which the back side shaft portion is inserted, wherein
by pressing on the operation portion, vale body press parts provided in the rear ends of arm members located on the valve seat member presses the taper part of the valve body, moving thereby the valve body backwards.

10. The liquid cosmetic container according to claim 9 ,
wherein the operation portion is made of an elastic material.

11. The liquid cosmetic container according to claim 9 ,
wherein container body and the operation portion are integrally molded by two-color molding.

12. The liquid cosmetic container according to claim 9 ,
wherein the taper portion has a truncated cone shape, including in the axial direction, and
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.

13. The liquid cosmetic container according to claim 9 ,
wherein a spring member is provided in the container body and a front end of said spring member is fixed and supported at the back end of the taper portion and another end thereof is fixed and supported at the spring supporting portion of the valve seat member such that the valve body is urged in the direction so as to be seated on the valve seat portion by said spring member.
