Abstract
In a pressure lid can (1) with an at least one-piece body member (2) and a lid member (4), which together with a body element (6) located at the closure-side end of the body member (2) forms a tight closure, in which a lever gap (26) between the body member (2) and the lid member (4) is left free for the application of a lever by means of which the lid member (4) can be levered up, the lid member (4) has an all-round, resilient engagement lip (8), which engages from the inside under pretension in a closure corrugation (10) of the body element (6) adapted to the engagement lip shape.
Claims6
A pressure lid can comprising
- a body member with a closure-side end having a radially outwardly bowed closure corrugation for interfittingly engaging an engagement lip and
- a lid member with a lid top and a closure border including an all-round resilient engagement lip, a ring flange and a resilient leg,
- said resilient leg passing from said lid top into said ring flange, said ring flange projecting substantially horizontally and radially outward from said resilient leg,
- said engagement lip being connected to said resilient leg via said ring flange and provided on said closure border radially outward of said ring flange and said lid top for interfittingly engaging into said closure corrugation under pretension from inside of said body member to form a tight closure while leaving an exposed lever gap between said body member and said lid member to permit engagement of a lever by means of which the lid member can be levered up, said lever gap being bordered by said resilient leg, said ring flange and at least a part of said closure-side end of said body member.
