Abstract

A pumping-type cosmetic container having a side button, and, when pressing a button part which is positioned toward a side so as to be crossed at a right angle to a container body, a first check valve is closed while a second check valve is opened, and the contents flowing into a cylinder are discharged outward through an applicator. Therefore, with a simple structure of the pumping-type cosmetic container having a side button, a user can directly apply a fixed amount of contents to a desired region.

First claim

What is claimed is:

1. A pumping-type cosmetic container having a side button comprising:
a container body wherein contents are held;
a cylinder part, placed at an upper portion of the container body and forming a passage where the contents move, the cylinder part further comprising a cylinder body which is placed toward a side so as to be crossed at a right angle to the container body, a contents inflowing tube which is extended to a lower portion of the cylinder body, forming a contents inflowing hole which leads the contents contained in the container body to flow into an interior of the cylinder body, and a content outflowing tube which is extended to an upper portion of the cylinder body, forming a contents outflowing hole wherein the contents flowing into an interior of the cylinder body can flow out;
a pumping member which is inserted into an interior of the cylinder body and discharges the contents by changing inner pressure of the cylinder body by a pumping movement;
a button part which is combined with the pumping member and delivers pressure to the pumping member by a pressing movement; and
an applicator which forms a contents discharging hole so that a user can discharge the contents through the contents outflowing hole and thereby apply the contents discharged outward onto a skin,
wherein the pumping member comprises a piston rod movable in an interior of the cylinder body and a seal cap coupled to and encasing an outer circumferential surface of the piston rod, the seal cap movably contacting an inner wall of the cylinder body, the pumping member further comprising a hollow stem fixed to an inner side of the button part and coupled to the piston rod, such that the stem receives the piston rod therein and applies a pressure to the piston rod according to the pressing movement of the button part, and a spring encasing an outer circumferential surface of the stem outside of the cylinder body, wherein the spring restores the button part by providing an elastic force to the stem while being contracted when the button part is pressurized, the spring being relaxed when the button part is unpressurized,
wherein the piston rod has a stroke so that an end of the piston rod moving in the interior of the cylinder body does not cover all of the contents inflowing hole and the contents outflowing hole, thereby preventing the piston rod from interfering with movement of the contents to the contents outflowing hole responsive to the pumping movement of the pumping member.

2. The pumping-type cosmetic container having a side button of claim 1 , further comprising a valve installing tube between the container body and the contents inflowing tube, the valve installing tube including a first contents movement hole so that the contents held in the container body can move into the interior of the cylinder body, wherein at the valve installing tube a first check valve is installed which opens/closes the first contents movement hole by the pumping movement of the pumping member.

3. The pumping-type cosmetic container having a side button of claim 2 , wherein the contents outflowing tube is equipped with a second check valve which opens/closes the contents outflowing hole by the pumping movement of the pumping member.

4. The pumping-type cosmetic container having a side button of claim 1 , further comprising a fixing tube at the contents outflowing tube, the fixing tube comprising a second contents movement hole so that the contents flowing out through the contents outflowing hole can move to the contents discharging hole.
