Embodiment Construction

[0033] The present invention will be further described below in conjunction with the examples.

[0034] Such as Figure 1-7 As shown, a welded metal bottle and can includes a can body and a mouth and neck on the can body. The mouth and neck are located on the upper part of the can body. 5. The tapered portion 5 has an included angle α relative to the vertical plane, and the included angle α is 5°; it also includes a curled portion located at the opening end of the middle diameter portion 4, and the curled portion is a three-layer folded inward wherein the middle diameter part 4 and the tapered part 5 are provided with threads to form a screw thread part 12, the lower end of the middle diameter part 4 forms a safety ring 13, the bottom of this metal welded bottle is a bottom cover 14, and the upper end is a The screw cap 7 that the shaped part 5 is threaded to fit.

[0035] The manufacturing method of this welded metal bottle can comprises the steps:

[0036] Cut the metal s...

Abstract

The invention discloses a welded metal bottle can and a manufacturing method thereof. The welded metal bottle can comprise a can body and a neck part on the can body, wherein the neck part comprises amiddle caliber part and a conical part arranged on the upper portion of the middle caliber part; the conical part is provided with an included angle alpha relative to a vertical plane, and the included angle alpha is 3-10 degrees; the manufacturing method comprises the steps of carrying out rolling and welding of a metal sheet after painting into a cylindrical tank body; reducing one open end ofthe can body to form the middle caliber part; and forming the middle caliber part to form the conical part on the upper portion of the middle caliber part, wherein the conical part is provided with anincluded angle alpha relative to a vertical plane, and the included angle alpha is 3-10 DEG. The welding metal bottle can and the manufacturing method have the advantages that the processing difficulty is greatly reduced; through three-layer folding process of a curling part and taper angle setting, the sealing performance of the manufactured welding metal bottle can is good, so that the coatingis not prone to peeling off; a screw cover rotates smoothly, and the sealing performance is good, so that the welding metal bottle can is not prone to rusting during containing liquid.

Description

technical field [0001] The invention relates to a metal container for containing beverages and its preparation process, in particular to a welded metal bottle and its manufacturing process. Background technique [0002] At present, in the field of metal packaging at home and abroad, there are mainly two types of metal bottles and cans: (1) Stamping and forming, which uses metal sheets with excellent ductility to form a cylinder and a bottom or a cylinder and a bottom Separate (the bottom side is sealed with the bottom cover), and the diameter of the cylinder and the opening end are reduced to form a mouth and neck, and the mouth and neck have a safety ring, a thread, and a crimp; (2) Welding , the metal sheet (coated and printed in advance) is welded and rolled into a cylinder, and one side of the cylinder is reduced in diameter to form a neck, and the neck has a safety ring, a thread, and a crimp. The other side of the cylinder is sealed with a bottom cover. [0003] On t...
