Bottle cork for vaccum preservation

Abstract

Disclosed is a bottle cap for vacuum preservation, comprising a cap main body consisting of a cylindrical cap tube inserted in a vessel, and a holder part extended from an end, located at a vessel inlet, of the cap tube; a piston airtightly inserted in the cap main body and axially sliding along the cap main body to release air in the vessel; and a valve member positioned in an end, located in the vessel, of the cap main body. The holder part is bent in such a way that its bent part is parallel to the cap tube, and the valve member opens and closes an air hole for introducing and releasing air in the vessel according to movement of the piston. The bottle cap can avoid disadvantages of deterioration of contents in the vessel, inconvenience of separately storing a pump, and loss of the pump. Furthermore, the vessel is readily vacuumized using the bottle cap.

Description

technical field [0001] The present invention relates to a bottle stopper that is combined with the opening of a bottle to open and close the opening, and more specifically relates to opening and closing the opening of a bottle or container to form a vacuum inside the bottle or container, and to store stored goods as much as possible by using the vacuum. A bottle stopper for vacuum storage that preserves the original taste of stored goods for a long period of time. Background technique [0002] Generally, containers are used for storing stored goods, have a plug for blocking an opening, and are formed in various shapes and materials depending on the shape and material of the container. [0003] The plug combined with such a container prevents the storage from flowing out by opening and closing the opening. In the case of a flowable product stored in the container, after the container is opened once, even if the plug is combined again, the storage cannot be preserved in the st...

Problems solved by technology

At this time, there is a problem that the pump cannot be integrally formed on the container.

[0017] In addition, although the general container with the above-mentioned air outflow and inflow valve is mentioned, there is also the problem of inconvenient storage due to the use of a pump, just like the above-mentioned bottle stopper.
