ABSTRACT:
A container comprising a web or blank of material of limited flexibility with wall portions in which at least one edge is separated from a bent-over edge strip portion by a bend line, is provided with a maximum degree of stability so as to avoid any outward bulging and to resist the resilient forces tending to cause a return to an initial position. For that purpose, the bend line is interrupted by at least one geometrical surface portion serving as a stabilizing member which projects both into the edge strip portion and also into the wall portions, and which is separated from both by desired or predetermined bend lines. The blank can be made of cardboard with a coating of aluminum film or foil, for lining the interior of the container and the bend line is interrupted by at least one geometrical surface portion which projects into both portions of the blank, which are adjacent to the bend line, that is to say, the edge strip portion and the wall portion, and the stabilizing member is separated from the edge strip portion and the wall by bend lines which are at least partly cut. In both cases, at least the bend line is preferably produced by stamping or embossing, or by perforations.
