Description

Sealing structure and bottle Technical Field The utility model belongs to the technical field of container sealing equipment, and particularly relates to a sealing structure and a bottle. Background The bottle is a container with higher use frequency in daily life, is commonly used for containing liquid and the like, and because the liquid has fluidity, the bottle body and the bottle cap are often required to be sealed. The sealing mode in the market at present comprises an end face sealing mode, namely, a sealing gasket is placed on the inner end face of a cover, when a bottle is screwed with the cover, the sealing gasket is pressed by the end face of a bottle mouth to enable the sealing gasket to deform, so that the sealing effect is achieved, and due to the sealing mode of pressing while rotating, friction is generated between the end face of the bottle mouth and the sealing gasket directly, the sealing gasket is easy to damage due to the fact that the sealing gasket is used for a plurality of times, and sealing failure is caused. The second is radial sealing mode, i.e. the side of the bottle is sleeved with a sealing ring, the sealing ring is extruded and deformed in the process of screwing the bottle, so as to achieve the sealing effect, and the sealing ring always rubs with the inner side of the cover in the process of screwing the cover, so that the sealing ring is very forceful in screwing or unscrewing, and the sealing ring is easy to damage for a plurality of times, so that the sealing is invalid. Disclosure of utility model In view of the above, the first object of the present utility model is to provide a sealing structure, which can prevent the abrasion of the sealing ring and prolong the service life of the sealing ring. The utility model solves the problems by the following technical means: the sealing structure is arranged on a bottle, the bottle comprises a bottle body and a bottle cap, and the bottle cap is in threaded connection with the outer side face of the bottle mouth of the bottle body; The sealing structure comprises: The outer side surface of the sealing ring is convexly provided with a sealing part, a slot is arranged between the sealing ring and the sealing part, and the upper end part of the bottle opening is inserted into the slot; The sealing ring is sleeved at the upper end part of the bottle opening, and the outer diameter of the sealing ring is smaller than that of the sealing part.
