Problems solved by technology

However, the existing aerosol-type aluminum packaging cans generally install a valve nozzle on the mouth of the can after filling the propellant, and the liquids such as the filling in the can are squeezed out by the pressure of the propellant in the aluminum can. The cans have the following disadvantages: firstly, filling food needs to be filled with a propellant at the same time, and the food and propellant are mixed together, which does not meet the safety and hygiene conditions; secondly, because

Embodiment Construction

[0025] A further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention:

[0026] As shown in the figure, the new aluminum packaging can includes an aluminum can body 1. The aluminum can body 1 is made by adding an appropriate amount of lubricant to a certain amount of aluminum sheet and fully stirring it evenly before being extruded by a stamping machine with a corresponding mold. , trimmed to length, shrunk shoulders and turned over by mechanical action. The aluminum tank body 1 is sprayed with a protective film (not shown) for anti-corrosion, so that the shelf life of the aluminum tank body 1 is longer after storing the liquid agent; the aluminum tank body 1 outer surface can also be coated with a mimeograph layer ( Not shown in the figure), so that it is convenient to mimeograph patterns and characters on the primer, mimeograph patterns and characters can be carried out according to customer requiremen...

Abstract

The invention discloses a novel aluminium packaging can and a production method thereof. The novel aluminium packaging can comprises a can bottom, a can cylinder, a can shoulder and a can opening, andthe design key points are as follows: a gasket which can slide along the axis of the cylinder wall is sheathed inside the can cylinder; the inner cavity of the can cylinder is divided into an upper cavity and a lower cavity which are divided by the gasket; the upper cavity is communicated with the can opening; the can bottom is provided with a through hole which is used for communicating the lower cavity and the outside of the packaging can; the inner surface of the can shoulder is a conical surface; the upper part of the gasket is provided with a projection which can lean against the inner side of the can shoulder in an overlaying manner; and the projection is a conical body which can be matched with the conical surface at the inner side of the can shoulder. The invention aims at providing the production method of the novel aluminium packaging can with easy processing method and high degree of automation, and the novel aluminium packaging cans with simple structure, low cost and convenient use which are manufactured by adopting the method.

Description

[technical field] [0001] The invention relates to a novel aluminum packaging can and a production method thereof. [Background technique] [0002] Aluminum packaging can is a packaging container widely used in various industries, such as food, beverages, insecticides, detergents, mousse for hair fixing, etc. Aluminum packaging cans are easy to operate, safe and reliable, and are very popular among users. However, the existing aerosol-type aluminum packaging cans generally install a valve nozzle on the mouth of the can after filling the propellant, and the liquids such as the filling in the can are squeezed out by the pressure of the propellant in the aluminum can. The cans have the following disadvantages: firstly, filling food needs to be filled with a propellant at the same time, and the food and propellant are mixed together, which does not meet the safety and hygiene conditions; secondly, because the tank material needs to be filled with high-pressure gas, the number of ...
