Embodiment Construction

[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0028] Such as Figure 1 to Figure 3 As shown, an aluminum screw-top packaging can includes a can bottom 1, and the bottom 1 of the can is provided with a bottom edge 11 that is extruded downward and protrudes downward from the bottom 1 of the can, and the edge of the bottom edge 11 extends upward with a can barrel 2. The bottom edge 11 is connected to the tank 2 through a transitional arc 12 that is concave inward to the tank 2, so that the compression and torsion resistance of the bottom of the bottle can be strengthened. The tank 2 shrinks upward to form a tank shoulder 3 , the lower part of the section of the tank shoulder 3 is an arc convex to the tank 2 , and the upper part is an arc concave in the tank 2 . The tank shoulder 3 shrinks upwards to form a tank neck 4. The tank neck 4 is provided with an annular groove 41 and an inclined prot...

Abstract

The invention discloses an aluminium screw-on packaging jar, which comprises a jar bottom. The aluminium screw-on packaging jar has the essential scheme that the jar bottom is provided with a bottom side which is moulded downwards in an extruding manner and is protruded out of the jar bottom downwards; the edge of the bottom side extends upwards to form a jar cylinder; the jar cylinder is shrunk upwards to form a jar shoulder; the jar shoulder is shrunk upwards to form a jar neck; the jar neck is = provided with an annular groove and an inclined bulge loop which is arranged at the upper end of the annular groove to incline upwards; an external thread is arranged at the upper end of the inclined bulge loop of the jar neck; a jar opening with a lip is arranged at the opening end of the jar neck in a flanging manner. The invention further discloses a manufacturing method for the aluminium screw-on packaging jar. The method comprises the following steps: a, cutting; b, stamping; c, stretching the jar cylinder; d, finishing and polishing; f, cleaning; g, protecting; h, necking and moulding; and i, cleaning and leak hunting. The aluminium screw-on packaging jar has advantages of high anti-pressing and anti-twisting strength, simple structure, anti-counterfeiting performance and simplicity in manufacturing.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of a packaging can, in particular to an aluminum screw-mouth packaging can and a manufacturing method thereof. 【Background technique】 [0002] The packaging bottles of medical aerosol cans used in the market are generally made of glass. Glass aerosol cans have the following disadvantages: low pressure capacity, poor light-shielding performance, and cannot be used to store the filling inside; The grade is low, the added value is low, and the bottle body of the glass packaging bottle is not easy to print, and it is usually marked with a label, which is poor in moisture-proof, waterproof and anti-counterfeiting. For this reason, people are more willing to use metal aerosol cans, which are light in weight, easy to carry, easy to operate during use, safe and reliable, and are deeply loved by users. The existing aluminum packaging cans have high production cost, low strength of the can body, insufficient vis...
