Description

[0001] VALVE OF CASE PUMP [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pump for a container in which liquid contents are stored, and more particularly, to a valve device for a container pump which can appropriately discharge the contents inside the case.

Containers in which the contents of the liquid phase are stored may have a pump arranged at the upper part so that the contents can be used little by little. These containers contain contents that can be used in small increments as needed, such as make-up cosmetics.

In the upper part of the container, a pump is configured to discharge the contents. The pump is configured to discharge the contents through a discharge port exposed to the outside by pressing a button.

A button is connected to a piston which can pressurize the inside of the container and suck the contents of the container. The piston moves in an internal pumping pipe such as a cylinder to pressurize or suck the inside of the container. .

The discharge port through which the contents are discharged is configured to be closed after the contents are discharged by the button. That is, inside the discharge port, there is formed a valve which can open and close the discharge port by a button.

The opening / closing structure of the discharge port closes the discharge port after discharging the contents to prevent the contents from being shattered through the discharge port and contamination of the discharge port due to the contents.

Various techniques have been disclosed for preventing leakage of contents and preventing contamination of the discharge port by valve shutoff. For example, there is a link type in which the button and the valve in the discharge port move when the button is pressed to open the discharge port.

Such a link-type valve blocking technology is realized by a link that opens and closes a valve by a button and a button, and a valve body which is connected to the link and is movable in a discharge pipe constituting a discharge port.

The pump of the container related to the liquid-phase discharge of the link type is complicated in structure and difficult to manufacture and assemble, which is disadvantageous in terms of production cost.

Also, the structure of moving the valve such as the link by the button is broken well, and when the contents have viscosity, the valve opening and closing the discharge port may not move in the discharge pipe.

In the case of a liquid having a viscosity as high as that of water, there are points in which it is difficult to obtain a liquid phase which is easy to use by spraying without being discharged in a droplet shape at the discharge port.
