Description

Technical Field

[0001] The utility model relates to the field of rubber sealing rings, in particular to an anti-falling type rubber sealing ring. Background Art

[0002] Most of the water cups we use in our daily life are equipped with cup lids, especially the water cups that people carry with them. A sealing ring is arranged on the inner side of the cup lid and is threadedly connected to the cup body of the water cup. The purpose is to increase the sealing of the water cup, so as to delay the heat dissipation of the hot drink inside and prevent the liquid in the water cup from spilling out.
