Description

Sealing structure and container

Technical Field

The utility model belongs to the technical field of bottles and cans for liquid packaging, and particularly relates to a sealing structure of a container.

Background

Bottles and cans are widely used for packaging liquids, and the opening thereof is usually required to be sealed reliably. Some products, such as high-end wine, are packaged both to meet sealing requirements and to be decorative. The double requirements of sealing and decoration are generally realized by adopting a mode of an inner sealing cover and an outer decoration cover. In this regard, in the prior art, various technical schemes have been provided, but because the hard material is difficult to realize reliable sealing, the inner sealing cover is mostly made of polymer flexible materials, but the problem is that the polymer materials are easy to age and deteriorate, so that not only the sealing effect is affected, but also the content is possibly polluted.

With advances in material processing technology, some hard materials have achieved a low cost mirror-surface fit between them that reliably seals liquids, such as ceramic materials. The utility model provides a sealing structure for contact sealing of an inner plug of hard material and the inner wall of a container mouth, which is particularly suitable for sealing structures of a ceramic container and a ceramic inner plug cover and is also suitable for other hard materials.
