Abstract
A method for producing a can formed from a can part and a flange part is provided, the flange part being formed as an annular body and, on a side oriented inward toward an axis of symmetry of the annular body, an interface forming a bearing for the can part. A base and a lateral wall are formed on the can part, and the can part is deep drawn and made into a target geometry with a defined wall thickness by virtue of the lateral wall being flow formed. The lateral wall has a formed interface with a material thickness greater than the wall thickness of the lateral wall, and the flange part is connected to the can part at the interface.

A method for producing a can which is formed from a can part and a flange part, wherein the flange part is formed as an annular body and has, on a side oriented inward toward an axis of symmetry of the annular body, a first interface which forms a bearing for the can part;
- wherein a base and a lateral wall are formed on the can part, and wherein the can part is deep drawn and made into a target geometry with a defined wall thickness by virtue of the lateral wall being flow formed, wherein the lateral wall has formed on it a second interface with a material thickness which is greater than the wall thickness of the lateral wall, wherein the second interface includes a first lateral sub-surface, a second lateral sub-surface, and a can end surface that extends radially outward from the first lateral sub-surface to the second lateral sub-surface, wherein the flange part is configured to connect to the can part at the second interface, wherein the can part is connected to the flange part by a sealing seam that is formed as a sealing weld, and wherein a force acting on the can part in the direction of the base of the can part is transmitted from the can part to the flange part not via the sealing seam, but via a form-fitting connection formed by the second interface.
A can having a can part and a flange part, wherein the flange part is formed as an annular body and has, on a side oriented inward toward an axis of symmetry of the annular body, a first interface which forms a bearing for the can part;
- and wherein the can part has a base and a lateral wall, wherein the can part is a deep-drawn part of which the lateral wall is flow formed and has a defined wall thickness, wherein the can part has a second interface with a material thickness which is greater than the wall thickness of the lateral wall, wherein the second interface includes a first lateral sub-surface, a second lateral sub-surface, and a can end surface that extends radially outward from the first lateral sub-surface to the second lateral sub-surface, wherein the second interface forms a bearing for the flange part, wherein the can part and the flange part are connected to one another via a sealing seam, and wherein a force acting on the can part in the direction of the base of the can part can be transmitted from the can part to the flange part not via the sealing seam, but via a form-fitting connection formed by the second interface.
A can comprising:
- a flange part with a flange end surface;
- and
- a can part with a base, a lateral wall, and a peripheral region at an open end of the can part that opposes the base, the lateral wall coupled between the base and the peripheral region, the lateral wall having a wall thickness that is less than a material thickness of the peripheral region, the peripheral region including a first lateral sub-surface, a second lateral sub-surface, and a can end surface that extends radially outward from the first lateral sub-surface to the second lateral sub-surface, and the can end surface configured to abut the flange end surface of the flange part to form the can.
