Leakage-proof heart-shaped cup cover

Abstract

The invention relates to a leakage-proof heart-shaped cup cover, which comprises a cover body, a direct drinking opening and a buckling layer buckled with a cup body, the direct drinking opening is formed in the upper end face of the cover body, and a heart-shaped sealing buckle used for sealing the direct drinking opening is fixedly connected to the upper end face of the cover body in a clamped mode. A special-shaped protrusion used for fixing the heart-shaped sealing buckle is embedded in the upper end face of the cover body, in the using process, the cover body is connected to the upper portion of the cup body in a buckled mode through the buckle layer, the direct drinking opening is sealed through the heart-shaped sealing buckle, and when drinking is needed, the heart-shaped sealing buckle is opened and placed in the special-shaped protrusion to be limited and fixed so as to be prevented from being lost. The heart-shaped sealing buckle comprises a sealing protrusion, a turnover plate and a fixing plate, a limiting groove is embedded in the upper end face of the cover body, the fixing plate is fixedly connected to the upper end face of the limiting groove, the turnover plate is rotationally connected to one end of the fixing plate, and the sealing protrusion is fixedly connected to the side, away from the lower end face of the fixing plate, of the turnover plate, and the sealing protrusion is matched with the direct drinking opening.

Description

technical field [0001] The invention relates to the technical field of sealing equipment, in particular to a leak-proof heart-shaped cup cover. Background technique [0002] At present, there are many designs for hot drink cup lids. The most common one is to have an insertion hole on the cup lid, and then insert the straw into the cup body to drink, or to form a closable and open drinking port on the cup lid. , when drinking, directly open the drinking mouth, you can drink. [0003] Through patent search, there are the following known prior art solutions: [0004] Application number: CN201810252160.3, application date: 20180326. The invention relates to a leak-proof and easy-to-open lid for a hot drink cup. There is also a return hole on the top, and the hot drink cup cover also includes a cover that closes the leakage cavity, and a plug that is connected to the cover and can close the drinking port, wherein the cover can be rotated around the center of the leakage cavity...

AI Technical Summary

Problems solved by technology

[0005] This prior art improves the air vent in the cup cover so as to prevent leakage while ensuring ventilation, but it does not seal the direct drinking port, and the existing direct drinking port sealing scheme is to seal the direct drinking port by using a stopper. It is airtight, the stopper is easy to fall off during use, and the stopper is very easy to lose and difficult to reuse. At the same time, when the cup cover is used, the cup body and the cup cover are not fastened due to the internal air pressure and the cup material is relatively soft. It is tight and easy to fall off, and the internal liquid can flow out with the gap between the lid and the cup body to pollute the surface of the cup body and affect the use of the cup body
