Cup

Abstract

The invention relates to a cup which comprises a cup body and a cup cover, wherein a sealing surface is arranged between the cup body and the cup cover; the mouth part at the inner side of the cup body is provided with a slot; the cup cover comprises an upper cover body and a lower cover body, and a connecting sleeve is arranged between the upper cover body and the lower cover body; the lower cover body is provided with a slide slot, and a slide block can move in the slide slot; a slip slot matched with the slot is arranged on the slide block; the slide block is also provided with a return spring, and one end of the return spring butts against the slide block, while the other end of the return spring butts against a stop part on the lower cover body; the upper cover body and the lower cover body can rotate, and the upper cover body is internally provided with a push block; and a moving push surface of the push block pushes the push block to move outwards. Because the cup body and the cup cover have no thread fit, the cup body and the cup cover can be sealed through the sealing surface between the cup body and the cup cover, thereby saving troubles of repeatedly screwing the cup cover, and the cup cover can be flatly placed only by placing the cup cover on the cup mouth, thereby saving the heat loss.

Description

cup technical field The present invention relates to a cup. Background technique The cup body and the cup cover of the existing cup are mostly sealed by thread fit. Because the screw thread is uneven, in order to keep the water in the cup warm, the cup cover must be unscrewed each time when drinking water, and then screwed back after drinking. Existing cups have the trouble of twisting the cup lid repeatedly every time they drink water. If the existing cup cover is directly placed on the cup body, the gap between the mouth of the cup body and the cup cover will not be flat when not twisted, and the heat will be lost immediately. Make the performance of the cup not ideal. Contents of the invention The purpose of the present invention is to provide a cup that can be placed flat on the mouth of the cup body to reduce heat loss, and can be tightly connected to the cup body and the cup cover when it is taken out. In order to achieve the above purpose, the present invent...
