Abstract
Abstract A package characterized in that it has a substantially rectangular bottom having only at two opposite ends an upstanding wall part, said wall parts having along their outer periphery in the zones where these wall parts are not connected to the bottom part, a flange, the generating lines of which flanges are parallel to the main surface of the bottom part and that to the flanges of the upstanding wall parts a separate closing cover of a sheet of easily printable material such as hard paper or thin white cardboard is applied which extends along the entire periphery of the upstanding wall parts with the exception of the bottom part and has generating lines also parallel to the bottom part. This makes it possible to use a simple closing cover from a flat sheet, for instance of paper or thin white cardboard, which can easily be printed and given an attractive appearance and the foodstuffs can be displayed for sale in the package in such a way that substantially only the closing cover is visible.
