the utility model provides a sealing bottle plug, includes fixed connection's lid and chock plug, and the external diameter of chock plug cooperatees with the bottleneck internal diameter, and chock plug outer wall is equipped with the arch with lid looks department along circumference, and the arch is used for cooperating with the recess on the bottleneck structure.

In a third aspect, the present application provides a sealing structure that adopts the following technical scheme:

the utility model provides a seal structure, includes bottleneck structure and sealed bottle plug, and the bottleneck structure has the bottleneck with inner chamber intercommunication, and sealed bottle plug includes fixed connection's lid and chock plug, and the external diameter of chock plug cooperatees with the bottleneck internal diameter, and the one end that the inner chamber was kept away from to the bottleneck structure just is located the bottleneck inner wall and is equipped with the recess along circumference, and chock plug outer wall and lid junction are equipped with the arch along circumference, and the arch is used for the recess cooperation on the bottleneck structure.

By adopting the technical scheme, after hot filling, the sealing bottle plug is covered on the bottle opening structure, so that the plug head stretches into the bottle opening, and the bulge is positioned in the groove on the bottle opening structure. When negative pressure is formed in the bottle opening after cooling, the bulge and the groove are further matched and pressed, so that the possibility of leakage from a gap between the plug and the inner wall of the bottle opening is reduced, and the sealing performance is improved.

In summary, the application has the following beneficial technical effects: by arranging the grooves on the inner wall of the end face of the bottle mouth and arranging the matched bulges at the positions corresponding to the grooves on the sealing bottle plug, the sealing performance of the bottle mouth under the hot filling process is improved.

Detailed Description

The present application is described in further detail below in conjunction with figures 1-3.

The embodiment of the application discloses a sealing structure.

Referring to fig. 1 and 2, the sealing structure comprises a bottle opening structure and a sealing bottle stopper, the bottle opening structure comprises a bottle opening body 1, a bottle opening 11 communicated with an inner cavity is arranged on the bottle opening body 1, one end far away from the inner cavity is provided with a groove 12 along the circumferential direction on the inner wall of the bottle opening 11, and the bottle opening 11 communicated with the inner cavity of the bottle body is arranged on the bottle opening body; referring to fig. 3, the sealing bottle stopper comprises an inner stopper 2, the inner stopper 2 comprises a cover body 21 and a plug head 22 which are fixedly connected, the outer diameter of the plug head 22 is matched with the inner diameter of a bottle opening 11, a bulge 23 is arranged at the joint of the outer wall of the plug head 22 and the cover body 21 along the circumferential direction, and the bulge 23 is used for being matched with a groove 12 on the bottle opening structure.

The outer wall of the bottle mouth body 1 is provided with threads 13, the sealing bottle plug also comprises an outer cover connected to the outside of the inner plug 2, not shown in the figure, and the outer cover is provided with internal threads for being connected with the threads 13 on the bottle mouth structure.

In other embodiments, the connection between the outer cap and the finish structure may also be in the form of a common snap fit.
