A container for storage of flowable media has a deformable fluidtight inner envelope, a deformable fluidtight outer envelope and a collapsible frame between the two envelopes. The frame has two mirror symmetrical sections which are pivotally connected to each other along two parallel first fold lines, and each section has two second fold lines which are parallel to the first fold lines and divide the respective section into a median panel and two outer panels. The median panels carry pivotable flaps at both ends, and each outer panel carries at its ends pivotable triangular reinforcing elements. The frame is made of cardboard and can be erected by exerting pressure against the outer sides of the first fold lines. This causes the panels of each section to pivot relative to each other along the second fold lines while the outer envelope folds the flaps. The flaps form the top and bottom end walls of the erected frame, and the reinforcing elements enhance the stability of the frame at its ends. Strips of adhesive tape are used to prevent collapse of the once erected frame. A nozzle extends through registering openings of the two envelopes and a flap of the frame and is bonded to the two envelopes.

A container, particularly for flowable media, comprising an inner envelope including a deformable bag having a first opening for admission or evacuation of flowable media; an erectable and collapsible frame surrounding said bag and including, in the collapsed condition thereof, two overlapping sections and two parallel first fold lines hingedly connecting said sections to each other, each of said sections having a plurality of panels and second fold lines parallel to said first fold lines and hingedly connecting the panels to each other, at least one of said sections further comprising two flaps for at least one of said panels of said at least one section and two third fold lines normal to said first fold lines and hingedly connecting said flaps to said at least one panel, said sections being pivotable relative to each other along said first fold lines, the panels of each of said sections being pivotable relative to each other along the respective second fold lines and said flaps being pivotable relative to said at least one panel along the corresponding third fold lines for erection of said frame preparatory to admission of a flowable medium into said bag; and an outer envelope including a deformable sack surrounding said frame and having a second opening in register with said first opening; at least in erected condition of said frame.
