Abstract
The invention relates to a container with a closure between an open body end of a container body and the edge region of a lid that can be pressed into the open body end in a sealing manner. The lid has a seal in an edge region. The body end (27) is bent outwardly by 180°, with a radius that is as small as possible, in accordance with the sheet metal thickness. The bent portion (27) rests with a first part portion (3) directly on the outer face of the container body. The end of this first portion (3), in order to form two further part portions (8, 11), is bent radially outwardly with respect to the container axis and then axially downwardly.
Claims18
Container with a closing between an open body end of a container body (1) and an edge region (2a) of a lid (2) configured to be sealingly pressed into the open body end, wherein
- the lid (2) has a seal (4) in the edge region;
- the body end—provided to cooperate with the seal (4)—is bent outwardly by 180° with a smallest possible radius of curvature or a largest possible curvature at a first bending point (7), and the whole bent portion (27) rests with a first part portion (3) directly on an outer face of the container body (1), is bent from a container axis substantially radially outwards at an end of the first part portion (3) and is then bent axially downwards, to form two further part portions (8, 11).
Closing end of a body end of a container body (1) suitable to be closed, the container body made of sheet metal, adapted for sealingly pressing an edge region (2a) of a lid (2) made of sheet metal therein, wherein
- the sheet metal lid (2) has a seal (4) in the edge region;
- the body end is bent outwardly by 180°, running closely (7), and the bent portion (27) rests with a first part portion (3) directly on an outer face of the container body, a further portion (8) is bent substantially radially outward at an end of the first portion (3) and a third portion (11) is bent axially downward from an end (8b) of the second portion.
Method for producing or shaping a body end of a container body (1) made of sheet metal, comprising the following steps:
- the body end is bent outwardly by 180°, running closely (7);
- the bent portion (27) rests with a first part portion (3) directly on an outer face of the container body;
- a further portion (8) is bent outwards, substantially radially or in an inclined manner with respect to a container axis, at an end (3a) of the first part portion (3);
- a third portion (11) is bent axially downwardly from one end (8b) of the second portion.
