Abstract

A cosmetic container according to an embodiment of the present invention may reduce a thickness of the container by improving a structure of the disc valve.

First claim

What is claimed is:

1. A cosmetic container comprising:
a base member;
a housing including a support sleeve placed on an upper surface of the base member, a center sleeve placed on the upper surface of the base member at an inner center of the support sleeve, a partition plate connecting an upper end of the support sleeve and an upper end of the center sleeve, a main storage space formed between the support sleeve and the center sleeve, and a temporary storage space formed inside the center sleeve;
a frame coupled to an upper end of the housing and having a hole of a predetermined size formed therein;
a stem coupled to the frame so as to be movable in a vertical direction while being accommodated in the hole and having a discharge port for discharging a cosmetic solution formed in a center thereof;
a piston assembly mounted on a bottom surface of the stem and accommodated in the temporary storage space; and
a disc valve mounted on a lower end of the center sleeve for selectively communicating the main storage space and the temporary storage space,
wherein the disc valve includes:
a ring-shaped fixing portion; and
a flap portion that extends from an end portion of one side of the fixing portion, and

wherein at least the fixing portion of the disc valve is disposed outside in a lateral direction from the piston assembly, the lateral direction being defined to be crossing with respect to a direction that the piston assembly moves in the vertical direction.

2. The cosmetic container of claim 1 , wherein a disc valve coupling portion into which the disc valve is fitted is formed to be recessed at a lower end portion of the center sleeve, and
wherein a depression portion and a protrusion portion are alternately formed at the disc valve coupling portion.

3. The cosmetic container of claim 2 ,
wherein a protrusion portion fitted into the depression portion of the disc valve coupling portion and a depression portion into which the protrusion portion of the disc valve coupling portion is fitted are formed alternately on an upper surface of the fixing portion.

4. The cosmetic container of claim 3 , wherein the flap portion is formed more flexible than the fixing portion.

5. The cosmetic container of claim 4 , wherein the flap portion extends obliquely from an inner edge of the fixing portion towards a center of a bottom surface of the base member, and
wherein the flap portion includes:
a first flap portion extending from the fixing portion; and
a second flap portion extending from an end of the first flap portion.

6. The cosmetic container of claim 5 , wherein inclinations of the first flap portion and the second flap portion are designed to be different from each other.

7. The cosmetic container of claim 6 , wherein an acute angle formed by the first flap portion and a horizontal plane passing through the end of the first flap portion is formed to be larger than an acute angle formed by the second flap portion and a horizontal plane passing through an end of the second flap portion.

8. The cosmetic container of claim 4 , wherein the flap portion is bent and extends downward from an outer end portion of the fixing portion,
wherein disc valve further includes one or a plurality of fitting protrusions protruding from an inner circumferential surface of the fixing portion, and
wherein the disc valve coupling portion is formed with a fitting groove into which the one or plurality of fitting protrusions are fitted.

9. The cosmetic container of claim 8 , wherein the base member includes a bottom portion in which a depression portion having a predetermined depth is formed in a central portion thereof, and a side surface portion extending upward from an outer edge of the bottom portion, and
wherein an outer circumferential surface of the flap portion is selectively in close contact with a locking protrusion that connects the bottom portion of the base member to the depression portion of the base member.

10. The cosmetic container of claim 9 , further comprising a plurality of guide protrusions protruding from the bottom portion of the base member, but disposed to be spaced along an edge of the depression portion of the base member,
wherein an inner surface of the guide protrusion is formed to be inclined so that the flap portion is guided toward the depression portion of the base member during assembly.

11. The cosmetic container of claim 1 , further comprising a gasket placed on an upper surface of the stem.

12. The cosmetic container of claim 11 , wherein a discharge port for discharging the cosmetic solution is formed at a center of the stem, and
wherein a gasket placing groove on which the gasket is placed is formed on the upper surface of the stem.

13. The cosmetic container of claim 12 , wherein a guide flow path for guiding a flow of the cosmetic solution discharged through the discharge port is formed to be recessed in the upper surface of the stem corresponding to an inside of the gasket placing groove.

14. The cosmetic container of claim 13 , further comprising a palette placed on the upper surface of the stem,
wherein a plurality of outlets are formed in the palette, and
wherein the plurality of outlets are formed along the guide flow path in a state in which the palette is placed on the stem.

15. The cosmetic container of claim 13 , wherein the guide flow path includes:
a first flow path including a plurality of circular flow paths having different diameters around the discharge port; and
a second flow path including a plurality of straight flow paths dividing the first flow path through the discharge port.

16. The cosmetic container of claim 1 , wherein the partition plate is formed of a metal material, and
wherein the support sleeve and the center sleeve are formed of plastic materials that are coupled to an outer edge and an inner edge of the partition plate, respectively.

17. The cosmetic container of claim 1 , further comprising:
an outer cover rotatably coupled to the base member by a hinge shaft;
a pressure member mounted on a side surface portion of the outer cover;
a locking protrusion formed on a side surface portion of the outer cover corresponding to an opposite side of the pressure member; and
a push button mounted on the base member at a position aligned with the locking protrusion and having a locking hook selectively coupled with the locking protrusion,
wherein the pressure member presses an outer circumferential surface of the base member at a point spaced apart from the hinge shaft.

18. The cosmetic container of claim 17 , wherein when the locking protrusion is separated from the locking hook, the outer cover is rotated by a rotation moment generated around the hinge shaft by a restoring force accumulated in the pressure member.

19. The cosmetic container of claim 1 , wherein the piston assembly includes a piston guide, and a piston body that passes through the piston guide, has an upper end portion fixed to the bottom surface of the stem, and moves in the vertical direction integrally with the stem,
wherein the piston body includes a piston sleeve passing through the piston guide and formed with an inlet and outlet of the cosmetic solution, and a flange extending in a radial direction of the piston sleeve from a lower end of the piston sleeve, and
wherein a plurality of through-holes are formed in the flange.
