Ultrasonic welding type anti-leakage beverage cup lid

Abstract

The invention relates to an ultrasonic welding type anti-leakage beverage cup lid which comprises a lid body and a seal cover. A groove is formed in a panel of the lid body; an annular flange is formed among the side wall surface of the groove, the panel and a circumferential outline surface of the lid body; a drinking port is located in one side of the annular flange; a leak receiving cavity is located on the opposite side of the drinking port; an avoiding cavity is further arranged between the leak receiving cavity and the drinking port; the seal cover comprises a first cover plate ultrasonically welded to the edge of an opening part of the leak receiving cavity and used for closing the leak receiving cavity, a second cover plate in turnover connection with the first cover plate and capable of closing the avoiding cavity, a third cover plate extending to the drinking port from the end part of the second cover plate, and a cover plug; and a through hole communicating with an exhaust hole is formed in the first cover plate. According to the ultrasonic welding type anti-leakage beverage cup lid provided by the invention, the leak receiving cavity is closed by adopting ultrasonic welding, so that the leakage probability in the delivery process can be greatly reduced; and meanwhile, the seal cover can repetitively open or close the drinking port, and a placement space is providedfor an upper lip, so that the comfort in drinking is further improved.

Description

technical field [0001] The invention belongs to the field of beverage cup lids, in particular to an ultrasonic welding type leak-proof beverage cup lid. Background technique [0002] At present, there are many designs for beverage cup lids, the most common ones are provided with intubation holes and air holes on the cup lid, and then the straw is inserted into the cup body to drink, or a closable and openable opening is formed on the cup lid. The drinking port, when drinking, directly opens the drinking port to drink. [0003] However, for hot drinks, such as coffee, it is provided with air holes and a drinking port on the cup cover, wherein the air holes mainly release the internal heat pressure and prevent the cup cover from separating from the cup body. Shaking causes coffee to easily leak out of the cup cover from the air hole, thereby causing complaints and complaints from buyers. Therefore, it not only increases the difficulty of delivery, but also may affect the sale...

Problems solved by technology

[0006] However, the applicant found in use that because there is no seal formed between the leak-connecting cavity and the cover, once in the delivery process, the amplitude of the bumps is too large, the beverage that leaks into the leak-connecting cavity still has the possibility of leakage. The design of the drinking mouth is not convenient for the user to place the upper lip, and the drinking comfort is low
