Embodiment Construction

[0036] For ease of description and illustration, the present invention primarily describes the fabrication and necking of aluminum aerosol cans that have been drawn and attenuated, but it should be understood that the application is not limited to such cans. The present invention can also be applied to the method of necking processing other kinds of aluminum materials, aluminum bottles, metal containers and profiles. It should also be understood that, for convenience, the term "aerosol can" is used throughout this application to include not only cans, but also aerosol bottles, aerosol containers, non-aerosol bottles, and non-aerosol containers.

[0037] The present invention relates to an aerosol can, and a method of manufacturing an aluminum alloy can, the performance of the aluminum alloy can is the same as or better than that of the conventional aluminum alloy can, and the aluminum alloy can is allowed to be carried out on it Produce high-quality printing and designs, with ...

Abstract

Aerosol cans, more particularly, aluminum aerosol cans made from disks of aluminum coil feedstock, are provided. A method for necking aerosol cans of a series 3000 aluminum alloy is also provided. The method prevents the cans from sticking in the necking dies and produces a can with a uniquely shaped profile. The aluminum aerosol cans that are produced have the attributes of strength and quality, while being produced at a cost that is competitive with steel aerosol cans.

Description

technical field [0001] The present invention relates to aerosol cans, in particular to aerosol cans made of aluminium. Background technique [0002] Beverage cans traditionally begin as rolled discs of aluminum stock that are machined into the shape of a beverage can. The sides of these cans are approximately 0.13mm thick. Typically, the body of the beverage can is one-piece, except for the top. [0003] In contrast, traditionally, aerosol cans are made in one of two ways. First, the aerosol can can be made of three sections of steel, namely a top section, a bottom section and a cylindrical sidewall with welds along the length of the sidewall. These three sections of steel are assembled to form the tank. Aerosol cans can also be made using the known cold extrusion process. In the cold extrusion process, a hydraulic head punches an aluminum billet to begin forming the can. The sides of the can were thinned to about 0.40 mm by extending the wall of the can using a thinni...
