Description

A kind of aluminium qualitative change wall abnormity packing jar and manufacture method thereof

[technical field]

The present invention relates to a kind of aluminium qualitative change wall abnormity packing jar and manufacture method thereof.

[background technology]

Packing jar is a kind of packing container that is widely used in various industries, can be used for filling with beverage, wine liquid etc., easy to operate, safe and reliable when packing jar uses, and is greatly favored by consumers.

At present, the packing jar using on market is generally to make of glass, and glass packaging bottle exists following shortcoming: shading poor performance, can not adapt to the thing of filling out in it, and the product specification of glass packaging tank is low, added value is low, and glass packaging tank can body is not easy to printing, conventionally adopts labeling to indicate, antifalsification is poor, meanwhile, on glass packaging heaviness, bottle labeling know moistureproof, water-proofness is poor, make to transport, to deposit cost high.For this reason, people bring into use aluminium packaging can, existing aluminium packaging can generally comprises: at the bottom of tank, tank cylinder, tank shoulder and tank mouth, when aluminium packaging can will reach relevant national standard requirement, the tank base thickness degree that one chip aluminium block strikes out packing jar need to guarantee deformation pressure and bursting pressure and can not arbitrarily change, simultaneously, tank mouth thickness will guarantee the also arbitrarily attenuation of quality of tank mouth crimping, under the deformation pressure and bursting pressure situation that meet in standard GB/T/T25164-2010, the wall thickness at packing jar can body position must be had more than needed, this part wall thickness more than needed is as thin in changed, can save material, thereby reduce production costs, existing packing jar does not arrange the groove that hand is grabbed in addition, is inconvenient to capture, therefore be necessary to improve existing packing jar and job operation thereof.

[summary of the invention]

The present invention seeks to have overcome the deficiencies in the prior art, a kind of aluminium qualitative change wall abnormity packing jar and production method thereof of tank cylinder wall thickness change be provided, it has, and manufacture method is simple, good looking appearance, crawl are convenient, can be effectively false proof, advantage that productive costs is low.

The present invention is achieved by the following technical solutions:
