ABSTRACT:
The invention relates to an improved pressurized container, such as an aerosol can, which has crimping and welding of the top wall to the side wall, and which can withstand internal pressurization exceeding 400 psi and as high as 450 psi. The containers have continuous or interrupted reinforcing welding and also a notch or weakened area in the side wall to thereby direct the location of the controlled venting. In this manner, a safe, non-explosive venting of the container can occur.
