Description

Technical Field

[0001] This utility model relates to the field of cup lid technology, and in particular to a leak-proof flip-top cup lid. Background Technology

[0002] A cup is a container used to hold liquids. Cups are common utensils in daily life. The use of cups can improve the civility of drinking. Cups come in different types and materials, and appropriate materials and shapes can be used in different occasions. In order to improve the heat retention of cups, a lid is needed. The use of a leak-proof flip-top lid can improve the sealing of the cup.

[0003] A search revealed Chinese patent CN221938986U, which discloses a quick-opening leak-proof cup lid. The lid includes a cup body detachably connected to its bottom, a top ring fixed to the top of the lid, a direct-drinking fixing ring fixed to the top of the top ring, a reversible bending assembly and a leak-proof mechanism fixed to the right side of the lid, a straw slot on the top of the lid, a positioning post fixed to the top of the lid, a positioning groove on the top of the lid, and a sealing sill fixed to the top of the lid. This quick-opening leak-proof cup lid allows the leak-proof mechanism to be flipped and fitted onto the top of the lid when not in use, thanks to the interlocking of its components. Internal rubber rings and strips further enhance the sealing, preventing liquid leakage and providing excellent leak-proof performance. A quick-opening groove on the left side of the top ring provides a point of application, allowing the user to pry open the leak-proof mechanism with their fingers, achieving a quick-opening effect and convenient drinking.

[0004] The above-mentioned technical solution can only improve the sealing and ease of opening the cup lid by using a rubber ring, and provide protection against side leakage. However, it is easy for the liquid inside the cup to leak out from the straw opening on the lid when the cup is tilted, which is not conducive to improving the safety of the cup lid. At the same time, it cannot provide better protection against accidental opening of the closed cup lid, which can easily lead to the cup lid being accidentally opened and leaking water. It is not conducive to further protecting the self-locking effect of the cup lid. Utility Model Content
