<p>A two or three piece metal container is adapted to hold a pressurized product for dispensing through a valve mounted on the container. The container has a safety venting system therein, whereby the product may be vented from a filled pressurized container through the system when an increase in internal pressure threatens to blow the top or bottom off the container. The venting system comprises a plurality of triple scores formed in the seam where the container body is joined to the top closure of the container. When the internal pressure of a filled container increases sufficiently, the periphery of the top closure buckles outwardly causing the residual of the main score in the triple score to fracture and thus produce a plurality of vents to permit the highly pressurized contents of the sealed container to safely escape and prevent end blow-off.</p> |
