Problems solved by technology

[0003] The above-mentioned cup lid structure often causes beverage leakage after fastening in use. To investigate the cause, the main reason is that the manufacturers of the beverage cup 2 and the cup lid 1 are usually different manufacturers, although the cup of the beverage cup 2 The caliber of mouth 20 is the same specification, but because the tolerances set by different manufacturers are not necessarily the same, so beverage cups 2 and cup lids 1 produced by different manufacturers often cause beverage leakage after fastening. Often heard, but widely criticized

Abstract

The invention provides a leak-proof structure of a lid of a disposable drinking cup, wherein the lid edge of the lid is provided with a fastening part, and the fastening part is used for fastening to a flange of a drinking cup. There is an internal groove at the bottom for the cup flange to be inserted into and fastened. It is characterized in that an annular leak-proof layer is adhered to the inner surface of the internal groove, and the annular leak-proof layer is correspondingly arranged on the cup flange. The position of buckling and contacting with the content groove is used to form a leak-proof seal on the flange of the mouth of the cup, thereby preventing beverage leakage after the cup lid is buckled with the beverage cup.

Description

technical field [0001] The invention relates to a leak-proof structure of a lid of a disposable drinking cup, especially a leak-proof structure of a lid of a disposable drinking cup that can prevent leakage safely. The annular anti-leakage layer is used to form a leak-proof seal on the cup mouth flange of the beverage cup, thereby preventing beverage leakage after the lid and the beverage cup are fastened together. Background technique [0002] Due to the prevalence of coffee and hand cup beverages, beverage cups 2 (such as paper cups, convenience cups, etc.) figure 1 As shown), it is widely used in large quantities, and its structure is mainly that a concave space 11 is provided on the inner surface of the cup cover 1, and a fastening part 12 is provided on the cover edge 121 of the cup cover 1. The fastening part 12 is provided with a content groove 123, and the two side surfaces of the content groove 123 are respectively provided with a first buckle edge 122 and a second...
