An aerosol container (10) dispenses a fluid product under pressure. A pressure relief mechanism (30) vents the container in a controlled manner when the container is subjected to excessive pressure so to prevent the container from bursting. The container has a container body (12) of a hollow, generally cylindrical shape. Pressurized contents of the container are expelled through a valve assembly (18) installed at one end of the container. An end piece (22) attached to the container body at the other end of the container has a first circular shaped section (26) surrounded by a ring shaped outer section (28). The pressure relief mechanism comprises U-shaped score lines (32) formed across the transition between the two sections of the end piece. These score lines create lines of weakness in the material from which the end piece is made for the end piece to fracture along the score lines when the pressure within the container exceeds a predetermined pressure level. This allows the container to vent a controlled manner rather than burst.
