Cross-section. 20 difficulties to avoid and a stackable one

In the case of sheet metal canisters, there is now a demand for canisters made of fine sheet metal that have a high Stackability raised, the individual canister has dimensional stability in the walls, so that the Due to their shape, containers have a firm hold when filled when they are rolled over one another. To achieve this stackability, no bulges can be stacked.

A particular disadvantage of the cut (Fig. 2), where "the right-angled bulging consists in the fact that the canisters, 45 mutually lying side walls, can be different or, for example, when stacked on pallets, one of the same length.

This curvature is shown in detail in FIG. 3 to be sold. This is intended to provide a reliable illustration in which the canister jacket 4 is attached to the dashed line between the two corner radii r sealing the lid in the can opening. This measure is intended, in particular, to prevent the plastic cover binding line 12 from being applied tangentially to a straight line. When it is pressed into the can opening, this connecting line forms a chord of the arc with which it is deformed in a controlled manner. Rather, the deformation should coat between the corner radii outwards from the outset in the direction of the edge that is curved. The arc of the jacket has to be guided over the can opening in order to bring about an attachment 65 of the tendon 12 with a height h in relation to the pressing pressure and to ensure the seal length / of the arc in the order of magnitude of approximately.
