Container comprising a relatively stiff, form-retaining supporting frame and a flexible shell member arranged therein

A container comprising a relatively stiff, form-retaining supporting frame and a flexible shell member arranged therein, said shell member forming a receiving space for material to be packaged, said supporting frame comprising a polygonal bottom member and a correspondingly shaped polygonal cover member, both having corners, each corner of the bottom member being connected with a corner of the cover member by a rod-shaped element, the flexible shell member having a circumferential sidewall and being connected with each rod-shaped element by a respective flexible loop member, each loop member, starting from a first point of attachment to the shell member, said first point of attachment being on an exterior of the sidewall, passes around said rod-shaped element and extends further to a second point of attachment to the shell member on the exterior of the sidewall, spaced from the first point of attachment, each loop member having a length greater than a multiple of the circumference of the respective rod-shaped element, the loop members keep the shell member within outer boundaries of the supporting frame when the shell member contains material to be packaged, wherein a strip-shaped member made from a flexible material is connected with the shell member on the exterior of the sidewall and at a location proximate the points where the loop member is attached to the shell member, said strip-shaped member having a length at least equal to that of said rod-shaped element and a width greater than that of the shell member as measured between said two points of attachment, with the associated rod-shaped element extending between the loop member and the strip-shaped member.
