Description

Technical Field

[0001] The utility model relates to the technical field of cups, and specifically relates to a straw cup. Background Art

[0002] Water cups are common products in our daily life and are containers for drinking water. There are many types of water cups, such as straight-drinking cups, straw cups, milk tea cups, etc. A common straw cup usually includes a cup lid and a cup body. There is a jack on the cup lid, and a straw is provided in the jack. Through the straw, the drink in the cup can be sucked.

[0003] When a user drinks the drink in the cup, negative pressure will be generated in the cup body, making it difficult to suck out; to avoid the above situation, manufacturers usually set a vent hole on the cup lid, and air is returned through the vent hole to balance the air pressure inside and outside the cup body, so as to facilitate the user to drink. For example, the straw cup mentioned in the patent with the publication number: CN214803981U and the name: Straw Cup. However, when the cup is not in use, the user also needs to use a sealing plug to block the vent hole to prevent liquid leakage, which makes it more troublesome for the user to use; in addition, there is an additional position (the vent hole on the cup lid) that needs to be sealed, which will invisibly increase the risk of liquid leakage and affect the user experience.
