1. A long material for stretching an opening edge of an opening of a flexible container,
the long material being resiliently bendable and comprising two free ends,
the long material being able to be brought, by means of resilient bending, from a non-use position, in which it is not used for stretching the opening edge, into an insertion position in which it is preloaded and endeavours to assume the non-use position,
the long material being able to be inserted into the opening in the insertion position,
the long material inside the opening being able to be brought into a use position, in which it is preloaded and endeavours to assume the non-use position, in such a way that the opening edge is stretched in a dimensionally stable manner, the free ends of the long material are spaced apart from one another and hold a portion of the opening edge therebetween in a straight stretched manner, and dimensionally stable stretching takes place exclusively in a region of the opening of the container, while the container remains flexible in a remaining region of the container,
the free ends being formed by handling means for holding the long material in the insertion position in a form-fitting manner, during insertion of the long material into the opening,
the handling means being formed by end portions of the long material, which form a starting angle, relative to a longitudinal axis of the long material, which is greater than 0°, and
the long material being formed by a strip-like flat material, wherein the end portions are bent out of a flat material plane of the flat material.
