Self-closing liquid packaging container and method for controlling liquid discharging of container

Abstract

The invention discloses a self-closing liquid packaging container and a method for controlling liquid discharging of the container. The container comprises a container cavity, a ball valve, a liquid outlet communicating with the container cavity and a valve seat arranged at the liquid outlet. The ball valve is matched with the valve seat to block the liquid outlet. The container further comprisestwo channels which extend from the liquid outlet to the same side of the container and are respectively a ball valve movable channel and a liquid outflow channel, wherein the tail end of the ball valve movable channel is closed, and the size of the ball valve movable channel is larger than that of the ball valve; and the tail end of the liquid outflow channel communicates with the exterior of thecontainer, and the size of the communication position of the liquid outflow channel and the ball valve movable channel is smaller than that of the ball valve. Through cooperation of the ball valve andthe two channels, self-closing of the liquid outlet is achieved through a simple structure, liquid can smoothly flow out of the container or flow back into the container, it can be guaranteed that most of the liquid can flow back into the container cavity, and the problems of dryness and deterioration caused by the fact that the liquid cannot flow back are solved.

Description

Technical field[0001]The present invention relates to the field of container discharge, and more specifically, to a self-closing liquid packaging container and a method for controlling container discharge.Background technique[0002]Most of the existing sealing treatments for liquid packaging bottle caps use screw caps, flip caps or stopper caps. The bottle cap needs to be opened when the container is used, and the bottle cap needs to be closed after pouring the liquid. The entire use process is relatively cumbersome;[0003]The existing liquid sealing method also uses a cross-opening silicone plug cover, which has a self-closing function, but the technical structure is complicated, the cost is high, and it is easy to cause spraying or sputtering due to excessive squeezing force. , And it is not easy to control the dosage randomly, so it is not suitable for most products. There is also a bead valve type aluminum can bottle cap structure in the existing liquid sealing method, which has a...
