BARRIER-TYPE LEAK-PROOF HOT DRINK CUP COVER
Document Type and Number:
WIPO Patent Application WO/2019/184396
Kind Code:
A1
Abstract:
A barrier-type leak-proof hot drink cup cover, comprising a cover body (1) having a leakage collecting cavity (10), a drinking opening (2), a seal cover (4) covering the leakage collecting cavity, and a partitioning barrier (5) that is disposed on the seal cover and can separate the leakage collecting cavity into first and second sections, wherein a space for containing leaked hot drink is formed between the seal cover and the leakage collecting cavity, and the seal cover and the leakage collecting cavity are provided with first and second through holes, respectively; the first and second through holes are respectively located in the first and second sections; when the seal cover is closed, the bottom of the partitioning barrier is attached to the bottom of the leakage collecting cavity, so that the hot air in the second section (10b) can flow to the first section (10a); the hot drink or foam in the second section cannot flow to the first section after being blocked by the partition barrier. Under the premise of ensuring that the air hole of the leak-proof hot drink cup cover is unobstructed, the hot drink in the cup can be prevented from leaking from the pressure-relief air hole, so that delivery is facilitated, the shape of the cup cover is able to change, and consumers may be attracted more easily.
