The check valve 30 allows the contents contained in the container body to flow from the container body to the discharge passage 22, but serves to limit the flow from the discharge passage 22 to the container body.

The pumping piston 50 serves to suck the contents of the container body into the discharge passage 22 and discharge the contents sucked into the discharge passage 22 to the spray portion 64 of the button cap 60.

Specifically, the pumping piston 50 is provided to be able to move up and down along the discharge passage 22 of the pumping housing 20, and has a flow path 52 through which the contents contained in the discharge passage 22 flow. Here, the flow path 52 may be formed along the central axis of the pumping piston 50.

When the pumping piston 50 is lowered, the internal volume of the discharge passage 22 is reduced, and as a positive pressure is formed in the discharge passage 22, the contents contained in the discharge passage 22 are distributed through the flow passage 52. It can be discharged into the sabu (64).

Afterwards, when the pumping piston 50 rises, the internal volume of the discharge passage 22 expands, and as pressure is formed in the discharge passage 22, the contents contained in the container body are sucked into the discharge passage 22. You can.

The pumping piston 50 may be coupled to the button cap 60. In this case, the pumping piston 50 may be raised and lowered as the button cap 60 is raised and lowered.

The button cap 60 serves to lower the pumping piston 50. At this time, the button cap 60 can be lowered by user manipulation.

In other words, the cap return unit 70 serves to raise the lowered button cap 60 to return it to its original position. In this way, the present invention raises the button cap 60 by using the elastic force of the cap return portion 70 made of the same material as the button cap 60, so that the contents stored in the container body are damaged due to corrosion of the metal spring. This deterioration can be prevented.

As an example, the cap return portion 70 may include a synthetic resin material. For example, synthetic resin is not particularly limited, but may be plastic.

As shown in FIGS. 1 to 5 , the cap return portion 70 may include a pair of support members 72, an elastic member 74, and a spacer 76.

A pair of support members 72 may be disposed on the button cap 60 and the pumping housing 20, respectively. The gap between the pair of support members 72 may increase or decrease as the button cap 60 is raised or lowered by the user's manipulation. For example, the support member 72 may have a ring shape.

The elastic member 74 can elastically support the pair of support members 72. This elastic member 74 can expand and contract as the button cap 60 moves up and down.

The spacer 76 can expand and contract according to the expansion and contraction of the elastic member 74 and generate elastic force to maintain the gap between the pair of support members 72. This spacer 76 can expand and contract as the button cap 60 moves up and down.

In one embodiment, the spacer 76 may have a smaller elastic modulus than the elastic member 74. In other words, the spacer 76 may have a relatively greater strain rate than the elastic member 74. Therefore, when the elastic member 74 and the spacer 76 are contracted and then restored by the lowering of the button cap 60, the spacer 76 is restored relatively faster than the elastic member 74 and the elastic member 74 It can provide assistive power for rapid restoration.

Hereinafter, the operation of the container pumping device according to an embodiment of the present invention will be described.

First, the pumping housing 20 is mounted on the opening of the container body.

Next, the button cap 60 is lowered. At this time, as the button cap 60 descends, the pumping piston 50 also descends. As a result, the internal volume of the discharge passage 22 of the pumping housing 20 is reduced, and as a positive pressure is formed in the discharge passage 22, the air or contents contained in the discharge passage 22 are moved to the pumping piston 50. It is discharged to the spray portion 64 of the button cap 60 through the flow path 52. At this time, the gap between the pair of support members 72 of the cap return portion 70 is reduced, and the elastic member 74 and the spacer 76 of the cap return portion 70 are contracted.

Afterwards, the button cap 60 is raised by the elastic force generated from the cap return portion 70. As a result, as the button cap 60 rises, the pumping piston 50 also rises. As a result, the internal volume of the discharge passage 22 expands, and a pressure is formed in the discharge passage 22, so that the contents contained in the container body can be sucked into the discharge passage 22 through the check valve 30. . At this time, the gap between the pair of support members 72 of the cap return portion 70 increases, and the elastic member 74 and spacer 76 of the cap return portion 70 are restored.

Here, when the elastic member 74 and the spacer 76 are restored, the spacer 76 is restored relatively faster than the elastic member 74 and can provide an auxiliary force for rapid restoration of the elastic member 74. . As a result, the expansion member 74 can be quickly restored.
