PURPOSE: To obtain a solid and smart spray can be hitting strongly and pressing a female die of an elliptical rod body against a female die of a die, drawing out an elliptical cylinder body having a circular opening part and an elliptical shoulder part from a metallic lump, and attaching a bottom plate to said cylinder body.

CONSTITUTION: A die hole 3 of an ellipitical shoulder part and a die hole 4 of a circular opening part are provided on the tip of a female die hole 2 of a die 1, a spray can material A of a metallic lump fitted into the die hole 2 is hit strongly and pressed impulsively by a rod body male fie 5 which has provided continuously an elliptical shoulder part 7 and a circular opening part 8 on the tip of a head part 6, and the can material A is drawn out of a gap α between the die holes 2W4 and the dies 6W8. In this way, an elliptical cylinder body A having a circular opening part (a) and an elliptical shoulder part (b) is formed, and an elliptical bottom plate (c) is attached to the bottom part opening part by means of wind-clamping, etc. In this way, a solid and smart spray can be manufactured efficiently and at a low cost.
