Description

Technical Field

[0001] The utility model belongs to the technical field of water cups, and in particular relates to a novel flap-type cup cover. Background Art

[0002] The existing flap-type cup lid generally requires the flap to be bent to overcome the buckle and separate from the lid body before opening. However, the life of this snap-on structure is relatively short. Since the cup lid is usually made of plastic material with limited wear resistance, the snap-on structure will continue to wear during the repeated opening and closing of the lid, resulting in the flap being unable to be snapped onto the lid body. In addition, in order to prevent the flap from falling off when the flap is closed with the lid body, the snap-on structure is generally designed to be relatively tight, resulting in the user needing to use greater force to open the flap, which is inconvenient to use. Therefore, improvement is needed. Summary of the invention
