Technical Field

The utility model relates to a bottle lid field, in particular to bottle lid.

Background

The rubber stopper is a kind of sealing equipment used in chemical experiment, and is made of rubber, also called rubber stopper. The application in the field of life is more and more extensive now, mainly used for the seal of liquid and keep, however, current bottle lid often only can carry out disposable encapsulation, and is relatively poor to the packing leakproofness that needs repeatedly unseal, for this reason, we propose a bottle lid to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a bottle cap, comprising: the bottle comprises a first bottle cap and a bottle stopper, wherein a filling block is arranged below the middle part of the first bottle cap, an inner lining is arranged on the outer ring of the filling block, a convex block is arranged in the middle of the filling block, a groove is arranged on the inner side of the lower end of the inner lining, and a convex ring is arranged on the outer side of the bottom of the convex block;

the bottle plug is characterized in that supporting blocks are arranged above the bottle plug, side convex blocks are arranged above the supporting blocks and are of outwards-outward-turning structural design, and sealing and installation can be better performed through the comprehensive design of the protrusions of the convex rings and the concave structures of the grooves and the structural design of the convex blocks in the bottle plug in a matching mode, so that the sealing performance of the structure is improved.

Preferably, the environment-friendly waste bottle cap is convenient to decompose, and the first bottle cap is internally designed to be in a hollow structure.

Preferably, the outside of the first bottle cap is provided with a friction block, so that the bottle cap has good buffering property, and the outside of the friction block is provided with a plurality of groups of longitudinal and transverse anti-slip stripes, so that the anti-slip property is improved.

Preferably, a sealing layer is installed above the bottom of the filling block in a tight fit mode.

Compared with the prior art, the utility model discloses following beneficial effect has:

the structural design of protruding piece for outwards turning up, through the arch of protruding ring and the comprehensive design of the indent structure of recess, the structural design of protruding piece in the cooperation bottle plug, can be better seal and install to can use the encapsulation of going on repeatedly, promote the leakproofness of structure.
