Lever ring having a slanted flat strip
First Claim
1. A lever ring for seaming to a body (20) and for receiving a closure layer (1) affixed with an edge by means of sealing and for bridging an inner space of the lever ring, to close the body (20) in a seam-connected position, wherein (i) the lever ring comprises a continuous flat web (3a, 3b, 3c) which radially outwardly changes into an edge rim (2) of the lever ring, a continuous groove (N1, N2, N3) extending between the edge rim and the flat web;
- (ii) the flat web is suitable for connecting an edge of the closure layer by sealing, and extends with respect to a plane of the closure layer (1), that has been connected by such sealing, at an angle (α

Abstract
The invention comprises a lever ring to be connected to a body (20) by means of a seam and for receiving a closure layer (1) that has been connected by means of sealing onto the edge and which bridges an inner space of the lever ring and, in the seam-connected condition, closes the body (20), wherein the lever ring comprises a continuous flat web (3a, 3b, 3c), which radially outwardly changes into a lid rim (2) of the lever ring, a continuous groove (n1, N2, N3) extending between the lid rim and the flat web, the flat web is suited for connecting the edge of the closure layer by means of sealing and extends at an angle (α1, α2, α3) differing from zero with respect to the plane of a closure layer (1) being connected by means of sealing in this fashion the holding force on the flat web is increased.

2. A lever ring for seaming to a body (20) and for receiving a closure layer (1) affixed with an edge by means of sealing and for bridging an inner space of the lever ring, to close the body (20) in a seam-connected position, wherein
(i) the lever ring comprises a continuous flat web (3a, 3b, 3c) which radially outwardly changes into an edge rim (2) of the lever ring, a continuous groove (N1, N2, N3) extending between the edge rim and the flat web; (ii) the flat web extends upwardly inclined from a horizontal plane and is provided with an inner curling (4) on its radially inner end so that a closure layer (1) affixed to it by sealing (30) introduces a substantial force component (z) into a sealing seam (30), so that the force component extends in an extension direction of the sealing seam, upon a pressure force (Fi) acting vertically to a plane of extension of the closure layer. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
