ABSTRACT:
Pack made from a single-piece board blank which is coated with a sealable plastic layer on its inside, with an at least approximately elliptical base section to which two side panels are hinged which in turn have sealing edge strips divided off from them by folding lines, and with folding lines to divide gusset sections off from the base section and the side panels. The folding lines which divide the base section continue in the side panels where they divide off end panels. Flap extensions are in addition provided on the sealing edge strips, which make it possible to flatten the sealing edge strips against the end panels.
