A kind of metal bottle manufacturing process and metal bottle

Abstract

Embodiments of the invention disclose a metal bottle manufacturing process and a metal bottle. The metal bottle manufacturing process comprises the following steps: a meal sheet after preprocessing is rolled and welded into a tubular bottle body; the bottleneck of the molded metal bottle body is rolled to form an anti-theft groove; the part above the anti-theft groove is rolled to form a thread; the end of the bottleneck is machined into an outward roll rim which is in sealing contact with a mouth screw cap; and a bottom cap and the metal bottle body are connected in a sealed manner by rolling. According to the manufacturing process of the embodiment of the invention, the meal sheet after preprocessing is rolled and welded into the tubular bottle body, the bottom cap and the metal bottle body are connected in a sealed manner by rolling, the process is simple, and the cost is low; the bottle neck is rolled to form the anti-theft groove and the thread to enable the bottle body to achieve screw-cap fastening and anti-theft functions; and the outward roll rim is machined and in sealing contact with a rubber ring and the like in the screw cap to enable the metal bottle to achieve a screw-cap sealing function.

Description

technical field [0001] The invention relates to the technical field of metal container manufacturing, and more specifically, relates to a metal bottle manufacturing process and the metal bottle. Background technique [0002] Metal containers are common containers in daily life. Compared with other material containers, metal containers are easier to transport and have stronger temperature and pressure tolerance, so they are widely used in the packaging of carbonated beverages. [0003] Most of the existing metal containers are of an easy-to-open structure. Once opened, the bottle body is damaged and cannot be sealed again, and the reusability is low. Contents of the invention [0004] In view of this, the present invention provides a metal bottle and can manufacturing process and a metal bottle to achieve the technical purpose that the bottle body can be opened and drunk immediately, can be resealed for use, and has a high degree of reusability. [0005] A metal bottle man...
