Side wall arrangement for a container and method for the production thereof and container having such a side wall arrangement

A method for producing a side wall arrangement for a container, in which the side wall arrangement comprises:

• several side walls that are configured to form a closed ring, wherein a loading hatch is provided on at least one side wall of the several side walls, said loading hatch being configured to close an opening in the at least one side wall when in a closed position, or open the opening when in an open position, and wherein the loading hatch is flexibly connected to the at least one side wall by way of a hinge, wherein:
• the loading hatch has a unitary side edge portion, the side edge portion having a reduced wall thickness relative to an adjacent portion of the loading hatch;
• the at least one side wall has a unitary side wall edge portion that bounds at least a portion of the opening, the side wall edge portion having a reduced wall thickness relative to an adjacent portion of the side wall;
• the side edge portion of the loading hatch and the side wall edge portion of the at least one side wall laterally overlap with each other when the loading hatch is in the closed position;
• at least one tab is provided on:
• (i) the side wall edge portion of the at least one side wall, or (ii) the side edge portion of the loading hatch;
• the loading hatch is movable into the open position or the closed position when opening and closing the loading hatch after overcoming a holding force produced by the tab, or after overcoming a holding force produced by the side edge portion of the loading hatch and the side wall edge portion of the at least one side wall laterally overlapping with each other;
• and in the closed position, (i) when the at least one tab is provided on the side wall edge portion of the at least one side wall, the side edge portion of the loading hatch is positioned between a portion of the side wall edge portion and the tab, or (ii) when the at least one tab is provided on the side edge portion of the loading hatch, the side wall edge portion of the at least one side wall is positioned between a portion of the side edge portion of the loading hatch and the tab, the method comprising:
• stamping the at least one side wall such that the hinge for flexibly connecting the loading hatch to the at least side wall is produced, and wherein the stamping reduces the wall thickness of the at least one side wall in at least one section of the at least one side wall,
• introducing a separation cut at the at least one section of the at least one side wall having the reduced wall thickness, wherein the separation cut forms the unitary side wall edge portion of the at least one side wall, and the unitary side edge portion of the loading hatch, wherein the separation cut extends from an end edge of the at least one side wall, and wherein the separation cut at the at least one section having the reduced wall thickness enables the side edge portion of the loading hatch and the side wall edge portion of the at least one side wall to laterally expand such that they laterally overlap with each other when the loading hatch is in the closed position,
• providing the at least one tab on:
• (i) the side wall edge portion of the at least one side wall, or (ii) the side edge portion of the loading hatch, such that, in the closed position, (i) when the at least one tab is provided on the side wall edge portion of the at least one side wall, the side edge portion of the loading hatch is positioned between a portion of the side wall edge portion and the tab, or (ii) when the at least one tab is provided on the side edge portion of the loading hatch, the side wall edge portion of the at least one side wall is positioned between a portion of the side edge portion of the loading hatch and the tab;
• wherein the side wall edge portion has a peripheral edge that bounds an entirety of an upwardly extending side of the opening, wherein the peripheral edge extends upwardly in a slanted direction relative to the vertical direction and relative to the top edge of the at least one sidewall, such that an upper end of the peripheral edge is closer to a center of the opening than a lower end of the peripheral edge, and such that an inwardly protruding upper corner region is formed by the side wall edge portion corresponding with an upper part of the peripheral edge.
