Description

Beverage container plug and beverage container

Technical Field

The utility model relates to a technical field of container for the beverage especially relates to a container bolt body for the beverage.

Background

The straw cup is a cup for drinking the beverage in the cup body through the drinking spout on the cover body, has good sealing performance, is not easy to leak water, has simple and portable drinking mode, and can be used as a special cup for infants and children to drink water. However, when the beverage is filled in the cup, a positive pressure state is formed inside the cup body when the beverage is higher than the room temperature, and at the moment when the button is pressed to open the cover body, the positive pressure inside the cup body can cause the beverage to splash out from the drinking spout pipe, so that the risk of dirtying and wetting clothes and even scalding is generated.

For solving the problem of drinking the mouth pipe water spray in the twinkling of an eye that uncaps, mainly there are two kinds of cock body structures on the market at present: the first is that a thin-wall valve plate with a straight or cross notch is added at the outer opening part or the inner bottom part of the drinking straw, and the internal pressure is resisted by the opening and closing force of the valve plate, so as to inhibit the splashing of the beverage at the drinking straw; the second is to arrange an air intake mechanism and an air exhaust mechanism on the plug body, and operate the air exhaust mechanism to release the air pressure in the cup before the upper cover is opened to open the drinking straw, so as to solve the problem of splashing of the beverage at the drinking straw, for example, a container for the beverage mentioned in patent 201410412779.8.

However, in the first prior art, although the valve structure on the straw can suppress the splashing of the beverage at the spout to some extent, the liquid can still break through the closing force of the valve when the internal pressure reaches a certain level. On the other hand, with respect to the second prior art, although it can effectively prevent the water spray problem, there are the following disadvantages: the exhaust hole and the air inlet hole are mutually independent, the structure of the plug body is complex, and the cleaning is inconvenient; the exhaust hole sealing element needs to be completely inserted into the exhaust hole, the assembly difficulty is high, and the problem of water leakage can be caused when the assembly is not in place; since the vent hole must be sealed in cooperation with the lower end of the button, the freedom of design of the location of the vent hole and the shape of the button is limited.
