Abstract

See full text

Elastically bendable elongate material with two free ends for stretching an opening edge of an opening of a flexible container. The elongate material, through elastic bending, is brought from a non-use position, in which it is not stretching the opening edge, into an insertion position, in which it is pretensioned and seeks to adopt the non-use position. In the insertion position it is inserted into the opening where it is brought into a use position in which it is pretensioned and seeks to adopt the non-use position such that the opening edge is stretched in a dimensionally stable manner, the free ends of the elongate material are at a distance from each other and between them hold a portion of the opening edge tensioned in a straight line, and a dimensionally stable stretching occurs only in the region of the opening while the rest of the container remains flexible.
