## Abstract

The present invention relates to a foundation container comprising a pump having convenient pressurization and, more specifically, to a foundation container comprising a pump having convenient pressurization, wherein the outer wall of a pump main body is formed in the shape of an inwardly concave janggu (a Korean traditional hourglass drum), thereby not delimiting a pumping method to vertically pressurizing the center of a pump upper body, but facilitating the discharge of the contents even though any region of the pump upper body is pressurized. In addition, the present invention relates to a foundation container comprising a pump having convenient pressurization, wherein productivity is improved due to easy mass production by integrating a pump upper body and a pump main body in one body and forming a discharge valve and a suction valve in the same shape so as to simplify the structure of a pump.

## Claims

### Claim 1

A foundation container including a pump having convenient pressurization, which includes an outer container body (10) and an outer container lid (20) hinged to the outer container body (10) so as to be opened and closed, the foundation container comprising:
an inner container body (30) coupled inside the outer container body (10);
a pump lower plate (40) coupled to an upper portion of the inner container body (30) to seal the inner container body (30), formed at an upper portion thereof with a suction hole (45), and having a suction valve (44) for selectively opening and closing the suction hole (45);
a pump main body (50) coupled to the upper portion of the pump lower plate (40), and having a cylindrical outer wall;
a pump upper body (60) provided at an upper portion of the pump main body (50), formed at an upper portion thereof with a discharge hole (65), and having a discharge valve (63) for selectively opening and closing the discharge hole (65); and
an elastic member (70) provided between the pump main body (50) and the pump upper body (60) to elastically support the pump upper body (60).

### Claim 2 (depends on 1)

The foundation container of claim 1, further comprising an auxiliary container (34) or a piston formed inside the inner container body (30).

### Claim 3 (depends on 2)

The foundation container of claim 2, further comprising an impregnation member (80) provided inside the inner container body (30) or the auxiliary container (34), and formed of porous foamed urethane.

### Claim 4 (depends on 1)

The foundation container of claim 1, wherein the pump lower plate (40) has a pump lower plate inner wall (41) and a pump lower plate outer wall (42) extending downwards, is formed on an upper inner side surface thereof with a latching sill (46) fitted with the pump main body (50), and has a seating annular groove (47) between the latching sill (46) and the suction hole (45).

### Claim 5 (depends on 1)

### Claim 6 (depends on 1)

The foundation container of claim 1, wherein the pump main body (50) has a seating annular protrusion (51) extending downwards so as to be fitted into a seating annular groove (47) of the pump lower plate (40), and a side surface seating portion (52) extends outwards from the seating annular protrusion (51).

### Claim 7 (depends on 1)

The foundation container of claim 1, wherein the outer wall of the pump main body (50) is formed at an outer circumferential surface thereof with an annular groove (53).

### Claim 8 (depends on 1)

The foundation container of claim 1, wherein the outer wall of the pump main body (50) is inwardly recessed in a shape of “> <”.

### Claim 9 (depends on 1)

The foundation container of claim 1, wherein the pump upper body (60) is formed integrally with or separately from the upper portion of the pump main body (50).

### Claim 10 (depends on 1)

The foundation container of claim 1, wherein the suction valve (44) and the discharge valve (63) have a suction valve blade (441) and a discharge valve blade (631) for selectively opening and closing the suction hole (45) and the discharge hole (65), respectively.

### Claim 11 (depends on 1)

The foundation container of claim 1, wherein the outer wall of the pump main body (50) outwardly protrudes in a shape of “< >”.

### Claim 12 (depends on 1)
