Metal container with glass lining and its making process

Abstract

The present invention relates to a metal container with an internal container made of glass, including an external shell which is made up by using metal and has an opened mouth, and in the internal cavity of said metal external shell an internal container made of glass is placed, and said glass internal container is fixed on the internal cavity of the metal external shell. Said ivnention also provides its production process, and can be used for making various package products, such as wine bottle, tea package container, health-care product container and other decorative containers, etc.

Description

Technical field [0001] The invention relates to a container and a manufacturing method, in particular to a metal container with a glass inner tube. Background technique [0002] Existing metal cups, metal bottles, metal jugs etc. generally all adopt metal to make, but when filling wine, food or cosmetics with metal, because chemical reaction takes place easily, so this kind of metal container is not applicable. There is also a metal shell container in which a glass inner tube is installed in the metal shell by mechanical assembly or welding sealing, such as a thermos bottle with a metal shell, and the glass inner tube in this container cannot be tightly matched with the inner cavity of the metal shell. Loose and cause breakage, and not suitable for complex craft modeling. People have also carried out various experiments for this reason, hoping to obtain the container that the glass inner tube and the metal shell closely cooperate, but in the productio...

AI Technical Summary

Problems solved by technology

[0002] Existing metal cups, metal bottles, metal pots, etc. are generally all made of metal, but when using metal to hold wine, food or cosmetics, chemical reactions are prone to occur, so this kind of metal container is not suitable

There is also a metal shell container in which a glass inner tube is installed in the metal shell by mechanical assembly or welding sealing, such as a thermos bottle with a metal shell, and the glass inner tube in this container cannot be tightly matched with the inner cavity of the metal shell. Loosening and causing breakage, and not suitable for complex craft molding

People have also carried out various experiments for this reason, hoping to obtain the container that the glass inner tube and the metal shell closely cooperate, but in the production process, because the metal shell has a larger expansion coefficient than the glass and the thermal conductivity is lower than the glass inner tube, the metal shell and the glass The inner tube cannot be cooled and shrunk in place at the same time, causing the metal shell to squeeze out cracks or even shatter the glass inner tube that has shrunk in place and can no longer shrink in the subsequent shrinking process.
