Abstract
Abstract A container for pressurized products wherein the container is formed of first and second container halves joined in a generally mid-height peripheral seam. Under abusive handling, the seam could open and a rupture type failure may occur. A shrunk plastics material film wrapper is applied along the central portion of the container in overlying relation to the peripheral seam and serves to permit controlled venting of the pressure from within the container in the event of such seam failure of the container per se.
