Claims
- 1. A pressure lid container comprising
- a body member and a lid member,
- said lid member having an all-around, resilient engagement lip for engagement with said body member from the inside under pretension and being insertable into a closure-side end of said body member to form a tight closure therewith, said engagement lip having an axial thickness,
- said lid member including a portion spaced radially inwardly from said closure-side end of said body member to define a lever gap between said body member and said lid member for the engagement of a lever to permit said lid member to be levered up,
- said closure-side end of said body member including an inwardly rolled, upper circumferential edge bead and an inwardly impressed crease, said upper circumferential edge bead having an exposed end so that said lever may be levered against it as a fulcrum,
- said inwardly impressed crease being below said inwardly rolled, upper circumferential edge bead at a distance essentially corresponding to the axial thickness of said engagement lip so that, when said lid member is inserted, said engagement lip is engaged between said inwardly impressed crease and said inwardly rolled, upper circumferential edge bead.
- 2. A pressure lid container according to claim 1, wherein a sealant is provided below the circumferential edge bead in the area with which the engagement lip engages.
- 3. A pressure lid container comprising a body member and a lid member,
- said lid member having an all-around, resilient engagement lip for engagement with said body member from the inside under pretension and being insertable into a closure-side end of said body member to form a tight closure therewith, said engagement lip having an axial thickness,
- said lid member including a portion spaced radially inwardly from said closure-side end of said body member to define a lever gap between said body member and said lid member for the engagement of a lever to permit said lid member to be levered up,
- said closure-side end of said body member including an inwardly rolled, upper circumferential edge bead and an inwardly directed step, said upper circumferential edge bead having an exposed end so that said lever may be levered against it as a fulcrum,
- said inwardly directed step being below said inwardly rolled, upper circumferential edge bead at a distance essentially corresponding to the axial thickness of said engagement lip so that, when said lid member is inserted, said engagement lip is engaged between said inwardly directed step and said inwardly rolled, upper circumferential edge bead.
