Abstract
Embodiments of a large container may include a container base and a circumferential container wall. An upper end of the wall is closed by a container cover in the form of a metal disc. An annular, circumferential support element is secured at an upper end region of the wall. The disc spans the upper open end of the container wall. A lower side of the disc is welded to the support element and/or to the upper end region of the container wall by a continuous first welding seam. An upper side and/or an edge of the disc is welded to the support element by a continuous second welding seam. The first and second weld seams have respective first and second roots which merge into one another or at least come together.
Claims25
A container, comprising:
- a container base;
- a circumferential container wall which forms a receiving space, the container wall having an upper end;
- an annularly encircling support element fixed on an upper end region of the container wall
- a cover which comprises a metal disc which spans the upper end of the container wall in a self-supporting manner and closes the upper end of the container wall;
- the metal disc having a lower side which faces the receiving space the lower side of the metal disc being welded in a gas-tight or liquid-tight manner to the support element and/or to the upper end region of the container wall by a continuous first weld seam which has a first root;
- the metal disc having an upper side and an edge, the upper side and/or the edge of the metal disc being welded to the support element by a continuous second weld seam which has a second root, the first root and the second root coming together.
the container wall is formed from helically bent sheet-metal webs.
A method for producing a container having a container base, a container cover and a circumferential container wall which forms a receiving space, the container wall having an upper end which is closed by the container cover, said method comprising the steps of:
- fixing an annularly encircling support element on an upper end region of the container wall;
- forming the container cover as a metal disc;
- spanning the upper end of the container wall with the metal disc in a self-supporting manner, and
- closing the upper end by
- (a) welding a circumferential gap in a gas-tight or liquid-tight manner by means of a continuous first weld seam, the circumferential gap being located between
- (i) a lower side of the metal disc, the lower side facing the receiving space, and
- (ii) the support element and/or the upper end region of the container wall, and by
- (b) welding the support element, by means of a continuous second weld seam, to the upper side of the metal disc and/or to an upper edge of the metal disc, the first weld seam having a first root, the second weld seam having a second root, the first root and the second root being merged into one another.
