PRESSURE RELIEF DEVICE FOR PRESSURIZED CONTAINER

摘要

A pressure relief device (16) for venting an internally pressurized container (10)and an aerosol can having a can bottom containing this pressure relief device. The pressure release device (16) includes a coined pressure vent (30 within a domed can bottom. The pressure vent is characterized by a venting pressure greater than about 500 psig. In addition, the can bottom resists eversion and/or failure along the mechanical attachment to the container body (12) at all pressures between the venting pressure and the longitudinal rupture pressure in the container body.
