Aforesaid screw socket aluminum packing jar is characterized in that: described can body is cylindrical.

Aforesaid screw socket aluminum packing jar is characterized in that: described tank neck is cylindrical.

Aforesaid screw socket aluminum packing jar is characterized in that: described outside thread is provided with 3 to 4 circles.

The method for making of aforesaid screw socket aluminum packing jar is characterized in that comprising following step:

A: fry sheet, in aluminium flake, add lubricant, mix;

B: punching press, be squeezed into thick tank base, thick tank base comprises at the bottom of the tank and the tank cylinder, the tank feather edge extends upward and forms the tank cylinder;

C: finishing clips to required length with the open end of thick tank base;

D: clean, the inside and outside foul of thick tank base is removed clean post-drying;

E: conservation treatment, to thick tank base internal spray, carry out Base coating, printing, glazing to thick tank base outer wall;

F: receive neck, the opening of described thick tank base is upwards shunk form tank shoulder and how many extruding and shrink and form the tank necks, the open end of tank neck is for filling with mouthful;

G: moulding tank neck, at the outer wall of the tank neck position roll extrusion outside thread near the tank mouth.

The method for making of aforesaid screw socket aluminum packing jar is characterized in that: the diameter of tank mouth is 20mm, tank base thickness degree 0.7-0.8mm, and can body, tank are takeed on identical with tank neck depth degree, are 0.14-0.16mm all.

Beneficial effect of the present invention has: the tank neck repeatedly pushes the contraction moulding, and the tank neck is provided with the outer convex threads of 3 to 4 circles, strengthens the resistance to compression of tank neck, anti-twist power, and method for making is simple, and degree of automation is high; Tank mouth diameter is 20mm, and the seal gasket that relative bottleneck uses and lid can be used small size, so that product materials is few, and low cost of manufacture.
