The columnar plug body for the container plug for quick opening and closing of the invention has the following beneficial effects:

First, the structure is simple and the cost is low. The column plug body of the container plug which is quickly opened and closed according to the present invention is provided with a vent hole in the center of the base, and a venting valve is arranged on the vent hole to realize the upward closing of the columnar plug body or the downward opening. During the process of the container, the pressure inside and outside of the container is maintained by the vent hole, and the parts are few, the structure is simple, and the cost is low;

Secondly, the pressure balance between the inside and outside of the container can be maintained during the opening and closing of the container, and the difficulty of opening and closing the container plug is reduced. When the container is opened, the column plug body is separated from the limit seat on the container plug, the vent valve is opened, and the inside and outside of the container are passed. The vent holes are connected, and the columnar plug body descends under the elastic force of the elastic sealing sleeve on the container plug. During the downward movement of the column plug body, the pressure inside and outside the container is always communicated through the vent hole to maintain the internal and external pressure balance, and the process does not need to overcome the pressure difference between the inside and the outside of the container (none When the vent hole is in this state, the pressure inside the container is greater than the pressure outside the container), such as a carbonated beverage containing soda or the like in the container. Because of the large amount of carbon dioxide gas in the carbonated beverage, the carbon dioxide gas gradually escapes from the inside of the liquid and is discharged from the vent hole to the outside of the container. The elastic sealing sleeve can quickly drive the columnar plug body to return to the natural state, and quickly open the container, thereby effectively avoiding The cylindrical plug body is difficult to descend during the opening process of the container plug due to excessive pressure inside the container, which reduces the difficulty of opening the container; on the other hand, the container plug is in the open state during the upward pulling of the columnar plug body to close the container, and the vent valve is opened. The inside and outside are communicated through the vent hole, and the pressure inside and outside the container is always balanced during the upward movement of the columnar plug body. When the columnar plug body is up until the vent valve is closed, the container is closed, so the column plug body does not need to be pulled during the ascending process. Overcoming the pressure difference between the inside and outside of the container (the pressure outside the container is larger than the pressure inside the container when there is no vent hole), it is easy to pull, and the cylindrical plug body can be pulled up to achieve the container closure with a small force, thereby avoiding the formation of vacuum in the upward pulling process. Need to overcome the upward pressure caused by the pressure difference between the inside and outside of the container Difficult to reduce the container closure difficult.
