Abstract

There is provided a cosmetic vessel. The cosmetic vessel includes an airless pump configured to discharge cosmetics accommodated therein by using a piston that rises in a cylinder, a discharge plate provided at one side of the airless pump and having at least one discharge hole, and a guide unit provided between the airless pump and the discharge plate. A lower end of the guide unit is combined with the piston and rises or falls in a state of being integrated with the piston.

First claim

What is claimed is:

1. A cosmetic vessel comprising:
an airless pump configured to discharge cosmetics;
a discharge plate provided at one side of the airless pump and having at least one discharge hole; and
a guide unit provided between the airless pump and the discharge plate,
wherein the airless pump comprises:
a cylinder having a first hole configured to receive the cosmetics in the airless pump;
a piston with a hollow-shape, rising in the cylinder and having a second hole on an external circumference; and
a piston ring provided around the piston and attached to an internal wall of the cylinder to open and close the second hole by rising,
wherein the guide unit comprises a piston combining unit protruding from a lower surface of the guide unit downward, the piston combining unit being combined with the piston, and
wherein the piston combining unit presses the piston ring downward while the guide unit falls.

2. The cosmetic vessel of claim 1 , wherein the airless pump comprises:
a sealing member combined with an external circumference of the cylinder and configured to seal a circumference of the piston combining unit at an upper end of the cylinder, and
wherein an external side of a lower end of the piston combining unit is blocked by the sealing member.

3. The cosmetic vessel of claim 1 , wherein the piston combining unit is integrated with the guide unit so that an entire height of the cosmetic vessel may be reduced.

4. The cosmetic vessel of claim 3 , wherein the piston combining unit is directly combined with the piston while surrounding an upper end of the piston and rises or falls in a state of being integrated with the piston.

5. The cosmetic vessel of claim 1 , wherein an outlet connected to an exit of the airless pump is provided in a center of the guide unit,
wherein the piston combining unit is hollow-shaped and is connected to the outlet, and
wherein an upper end of the piston is inserted into a part of the outlet through the piston combining unit so that the upper end of the piston is higher than a lower surface of the guide unit.

6. The cosmetic vessel of claim 5 , wherein the guide unit comprises:
a first flow path configured to diffuse the cosmetics discharged by the airless pump; and
a second flow path connected to the first flow path to transmit the cosmetics to the discharge hole.

7. The cosmetic vessel of claim 1 , wherein, in the airless pump, when the piston falls due to pressing of the guide unit, after the second hole deviates from the piston ring and is connected to an inside of the cylinder, since the piston ring falls due to the guide unit so that internal pressure of the cylinder rises, the cosmetics in the piston are discharged.

8. The cosmetic vessel of claim 1 , wherein the airless pump further comprises an elastic member having elastic force that pushes the guide unit upward.

9. The cosmetic vessel of claim 8 , wherein the piston further comprises a flange provided in a lower end of the piston to support a lower end of the piston ring.

10. The cosmetic vessel of claim 9 , wherein, in the airless pump, when pressing of the guide unit is released and the piston rises due to the elastic member, after the second hole is blocked by the piston ring and is closed, since the piston ring rises due to the flange so that the internal pressure of the cylinder falls, the cosmetics are received to an inside of the cylinder.

11. The cosmetic vessel of claim 8 , wherein the elastic member surrounds the piston combining unit and has an upper end thereof contact a lower surface of the guide unit to push the guide unit upward.

12. The cosmetic vessel of claim 1 , wherein the discharge plate is exposed to the outside and is formed of metal.

13. The cosmetic vessel of claim 1 , wherein the discharge plate falls in a state of being integrated with the guide unit due to external pressure.

14. The cosmetic vessel of claim 1 , wherein the airless pump discharges the cosmetics to the outside by the falling of the discharge plate.

15. The cosmetic vessel of claim 1 , further comprising a vessel main body configured to store the cosmetics.

16. The cosmetic vessel of claim 15 , further comprising:
a first frame unit provided outside the discharge plate;
a second frame unit in which the discharge plate is settled and which is combined with a lower side of the first frame unit; and
a third frame unit provided on circumferences of the first frame unit and the second frame unit and fixed to the vessel main body,
wherein the first frame unit and the second frame unit have a circumference of the discharge plate fixed therebetween and may rise or fall based on the third frame unit.

17. The cosmetic vessel of claim 1 , further comprising a frame unit provided outside the discharge plate and combined with the outside of the guide unit,
wherein the frame unit and the guide unit fix the circumference of the discharge plate therebetween.
