Description

Heat insulation cup

Technical Field

The utility model relates to the technical field of daily necessities, more precisely relate to a thermos cup.

Background

The thermos cup is an article frequently used in daily life of people, and in order to prevent the thermos cup from leaking water, block a heat transfer channel and improve the heat preservation effect, sealing measures can be usually taken between the cup cover and the cup opening of the thermos cup. In the prior art, the cup covers of some vacuum cups are in threaded connection with the cup mouths, sealing rubber rings are arranged on the top portions of the inner sides of the cup covers, and the cup covers are screwed tightly, so that the cup mouths are sealed by the sealing rubber rings on the top portions of the inner sides of the cup covers in a pressing mode. By adopting the mode, if the cover of the cup cover is too loose, water in the cup can flow out along the sealing rubber ring, so that the water leakage of the cup is caused; if the cup cover is too tight, the sealing rubber ring in the cup cover is easily fatigue-failed due to over-compression, and water leakage of the cup can be caused in the long term. In other heat-insulating cups, a sealing rubber ring is arranged on the connecting thread of the cup cover, and the cup cover is screwed tightly, so that the sealing rubber ring is in interference fit between the cup cover and the connecting thread of the cup opening to seal the cup opening. By adopting the mode, when the cover is opened or the cover is tightly covered by rotating the cover, the sealing rubber ring on the connecting thread of the cover can generate friction noise with the cup opening, so that the user experience is poor.
