Efficient manufacturing method of insulated container and manufactured insulated container

Abstract

The invention discloses an efficient manufacturing method of an insulated container and the manufactured insulated container. The efficient manufacturing method comprises the following steps that A, an inner shell is mounted in an outer shell to form a container body, the container body forms an insulated cavity between the outer shell and the inner shell, and meanwhile a low-temperature sealing layer and a substrate layer are welded to each other to form a sealing piece; B, an exhaust groove is formed in the sealing piece, an exhaust hole is formed in the exhaust groove, and meanwhile an installing hole is formed in the bottom of the outer shell. The sealing piece and the bottom of the outer shell are welded to seal the installing hole, so that machining is more convenient, splicing of the container body and the preparation of the sealing piece are achieved synchronously, and the production efficiency is improved. The improvement cost of a production line is low. The low-temperature sealing layer and the substrate layer are both made of metal materials, so that compared with glass cement, the fusion degree is better; and the metal low-temperature sealing layer is not prone to breakage, and air can be effectively prevented from entering the insulated cavity through the exhaust hole.

Description

technical field [0001] The invention relates to the field of vacuum heat-retaining containers, in particular to an efficient method for manufacturing a heat-retaining container and a heat-retaining container manufactured therefor. Background technique [0002] The existing tailless vacuum insulation container manufacturing method is to use glass glue on the outside of the container body to seal the cavity at the bottom of the container body. Only when the container body is packaged can the grooves be pressed and holes punched, and the production efficiency is low. And because the main body of the container is made of metal, while the glass glue is a non-metallic material, the degree of fusion and adhesion between the glass glue and the container body is not good, and the glass glue is easy to crack due to high temperature or vibration. The glue is easy to fall off, and the air enters the insulation cavity, causing the vacuum insulation container not to keep warm. Contents ...
