Description

Technical Field

[0001] This utility model belongs to the field of cup lid technology, and in particular relates to a double-drink inner plug structure with good sealing performance and preventing spillage. Background Technology

[0002] Flip-top straw cups typically use a single flip-top straw structure or replace the drinking spout with an air vent plug. They often have problems such as inconvenient flip-top straw operation, or a small spout that makes drinking or pouring difficult. Additionally, the flat-sealed lid can result in poor heat retention.

[0003] Authorization announcement number CN219661382U discloses a dual-drinking inner stopper lid structure with a flip-over straw, comprising: a cup lid, the cup lid being disposed on a cup body; an inner stopper connector, located inside the cup lid, the inner stopper connector being installed on the cup body, the inner stopper connector having an installation groove; a flip-over spout assembly, connected to the installation groove, the flip-over spout assembly corresponding to the spout through hole opened in the installation groove; and a direct drinking spout, opened on the inner stopper connector.

[0004] The above technical solution uses a combination of hooks and locking points to connect the flip cover. However, when the hooks are used on vacuum vessels, if the hooks are too loose, there is a risk that the hooks will pop open and splash when the gas pressure in the vessel is too high. If the hooks are set too tight, it will be difficult to open and inconvenient to use. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a leak-proof double-drink inner plug structure with good sealing performance, aiming to solve the problems existing in the background art.

[0006] This utility model embodiment is implemented as follows: a well-sealed, anti-spray double-drink inner stopper structure includes:

[0007] The first connecting cover is connected to the second connecting cover.

[0008] The straw is movably installed on the water outlet of the first connecting cover;

[0009] A flip cover is movably mounted on the straw. The flip cover is provided with a guide block, which cooperates with a guide groove provided on the first connecting cover. The flip cover is connected to the first connecting cover through the cooperation of the guide block and the guide groove, which drives the straw to flip over and seal with the first connecting cover.

[0010] Preferably, the straw is provided with a connecting shaft, and the flip cover is provided with a connecting hole corresponding to the connecting shaft. The flip cover is rotatably mounted on the straw through the cooperation of the connecting hole and the connecting shaft.
