Built-in bottle cap and sealing structure

Technical Field

The utility model relates to a bottle seals technical field, in particular to lid and the seal structure of bottle, jar class bottle of splendid attire liquid. The bottle of the utility model also comprises a jar or a can-shaped bottle.

Background

Some industries, such as the white spirit industry, have high requirements for packaging bottled products. While ensuring the sealing, the anti-counterfeiting requirement is also met. One requirement is that the sealing structure needs an inner layer and an outer layer, and the outer layer structure needs to be damaged to a certain extent when being opened and cannot be completely restored; the inner layer structure can be provided with (sprayed or etched) anti-counterfeiting marks (such as anti-counterfeiting codes and traceable information). Some bottle caps meeting the anti-counterfeiting requirement exist in the prior art, but various defects exist, or the structure is too complex, or the function of sealing the bottle mouth after the outer layer structure is opened is also damaged, and the like. In order to overcome the defects of the prior art, the applicant has already proposed several patent applications of improvement schemes. The utility model provides a simple structure is practical's built-in bottle lid and utilizes bottleneck sealing structure of this kind of bottle lid.
