Description

Technical Field

[0001] The utility model relates to the technical field of PET cups, in particular to a leak-proof PET cup. Background Art

[0002] PET refers to polyethylene terephthalate, with the chemical formula (C10H8O4)n. It is obtained by ester exchange of dimethyl terephthalate and ethylene glycol or esterification of terephthalic acid and ethylene glycol to synthesize dihydroxyethyl terephthalate, and then polycondensation. It is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. It is a common resin in life and can be divided into APET, RPET and PETG.

[0003] In Chinese Patent 202320834889.8, the utility model discloses a leakproof PET bottle, which belongs to the technical field of PET bottles. It includes a bottle body, and also includes: a circular bottle groove, which is arranged inside the bottle body; a bottleneck, which is fixedly arranged at the upper end of the bottle body, and the outer wall of the bottleneck is provided with an external thread; a bottle cap, which is arranged above the bottle body, and the bottle cap is threadedly connected with the external thread through an internal thread; a bottle mouth, which is arranged inside the bottleneck, and the bottle mouth is connected with the circular bottle groove. The utility model solves the problem that the water droplets left after pouring or drinking water from the PET bottle in the prior art are easy to drip on the table or flow on the outer wall of the bottle body, and it is troublesome to wipe it by yourself. By setting a sealing ring, it has a sealing effect, so that the connection between the bottle cap and the bottleneck is tighter, and liquid will not leak easily. When the pouring is completed, the water droplets left at the bottle mouth can fall on the convex ring when the bottle body returns to the tilted state, effectively preventing the water droplets from flowing on the outer wall of the bottle body.
