Description

Pump vessel with double check plate structure

The present invention relates to a pump container having a double check plate structure for pumping the container lid to discharge the liquid contents of the container body.

Liquid cosmetics are generally stored in storage containers such as pump containers, tube containers and dropper containers. Among them, the pump container is widely used due to the advantage that the liquid cosmetics can be discharged with only a simple operation of the user.

Conventionally, the pump container has a structure for discharging the contents stored in the container body when pressure is applied to the container lid. Such a pump container may not only discharge the amount of contents desired by the user according to the pressure applied to the container lid, but also accurately discharge the contents in the direction desired by the user.

However, the conventional pump container allows the contents to be discharged from the container body to the container lid by simply pressing the rubber member located between the container lid and the container body or by applying pressure to the space between the container lid and the container body. That is, the conventional pump container is a space located between the container lid and the container body because the contents are discharged to the container lid straight from the inside of the rubber member or only by the pressure applied to the space between the container lid and the container body. There was a disadvantage in that the pressure could not be effectively controlled.
