Cover pressing die of threaded mouth ofglass bottle

Abstract

The invention provides a cover pressing die of a threaded mouth of a glass bottle, which is applicable to the threaded mouth of the glass bottle. According to the cover pressing die, the interior of the cover pressing die is concavely arc shaped, and is provided with a clearance structure; when in use, the bottle cover to be subjected to pressing is automatically guided to a bottle cover furbelow to contact with the concave arc through the pressing die, the clearance at the concave arc can absorb the elasticity of the bottle cover after being subjected to pressing, so that the pressed bottle cover has no indentation, and the bottle cover can be kept in a proper elasticity, so that the bottle port can be sealed, and also can be manually screwed to open by a user.

Description

Technical field: [0001] The invention relates to the field of moulds, and mainly relates to a capping mold for crown caps of screw-necked glass bottles. Background technique: [0002] The function of the capping die for screw-top glass bottles is to stamp the crown cap and seal the bottle mouth. The traditional capping die has only one overall radian, and the crown cap is pressed tightly on the glass bottle mouth by using a convex arc. In the case of a screwdriver, people cannot open the glass bottle with bare hands, and the crown cap opened with a bottle screwdriver can no longer be used to seal the mouth of a beer bottle. After a new search, it has been found that there is a similar patent application, which is a gland mold 200720061190.3, it is that the arc-shaped protruding structure inside the capping mold is in contact with the bottle cap, and the cap cannot be tightly sealed. Invention content: [0003] The object of the present invention is to provide a screw cap ...
