Description

A cup lid with a lever opening and closing Technical Field

[0001] The utility model relates to a cup cover that opens and closes in a lever-type manner, belonging to the technical field of thermos cups. Background Art

[0002] Cups are essential items in people's daily lives. They can be categorized into various types based on their purpose, such as water cups, coffee cups, hot drink cups, and thermos cups. Taking thermos cups as an example, thermos cups are generally made of materials such as ceramic, stainless steel, or titanium alloy. They feature a vacuum layer inside the cup body and a sealed lid on top. This vacuum layer insulates the water or other liquids contained within the container from the outside world, achieving the purpose of heat preservation or cooling. The internal structure of a thermos cup typically consists of multiple layers. The vacuum layer is used to prevent heat conduction, and the outer wall of the vacuum layer is plated with silver to prevent heat radiation. A thermos cup typically includes a cup liner, an outer shell, and a lid.

[0003] Conventional cup lids typically open by securing the lid to the cup body via a threaded connection, which offers a simple structure and reliable connection. However, this threaded connection requires the user to use both hands to remove the lid, which can be inconvenient in some situations. Furthermore, the user must repeatedly tighten or loosen the lid before and after each use, significantly reducing closing and opening efficiency. Utility Model Content

[0004] The utility model provides a cup cover which is opened and closed by toggling a lever on the upper end of the cup cover left and right in cooperation with a locking assembly, and the lever block drives the exhaust valve downward to realize exhaust, thereby solving the problems existing in the prior art.
