Lid for beverage container and beverage container

Abstract

The objective of the invention is to provide a cap for drink container and drink container, capable of effectively preventing ejecting of drink from drink port caused by raising internal pressure and easy to decompose and clean. The invention, characterized in that, has a cap body mounted on the opening of the container body with watertight and a sucker with flexibility, the cap body has a screening part for separating inside and outside of the container; by bending and extending the sucker to open and close valve device of internal channel and venthole device of the venthole provided on the screening part, the sucker runs through in the screening part after making watertight around the sucker.

Description

technical field [0001] The present invention relates to a lid for a beverage container with a drinking straw such as a straw, and a beverage container using the same. Background technique [0002] Conventionally, a liquid beverage is packed into a container body having an opening, and the opening of the container body is sealed with a lid body provided with a drinking straw such as a straw to prevent leakage to prevent liquid from leaking out, and water can pass through when drinking. Beverage containers of the type having drinking straws and drinking beverages from drinking straws are known. [0003] However, since in such beverage containers, the front end of the straw extends into the liquid beverage, there is a problem that the air inside the container is heated when the liquid beverage is warmed, so that the internal pressure rises, and when water is passed through the drinking straw Squeezed by air pressure, causing the warm liquid beverage to be ejected from the drin...

Problems solved by technology

[0003] However, since in such beverage containers, the front end of the straw extends into the liquid beverage, there is a problem that the air inside the container is heated when the liquid beverage is warmed, so that the internal pressure rises, and when water is passed through the drinking straw Squeezed by air pressure, causing warm liquid beverages to be ejected from the drinking spout

[0008] However, on the point of providing a valve core for opening and closing the communication channel inside and outside the container on the shaft portion on which the straw cap is swingably mounted around the horizontal axis, as in Patent Document 1, a vent hole is provided on the rotating shaft portion, and there is also a winding. The problem of impurities or dust entering, because the connecting channel is composed of a complicated structure, it is difficult to clean, and it is also difficult to perform cleaning and maintenance such as disassembly
