ABSTRACT:
This invention relates to a folding box comprising a flexible sheet consisting of a single layer of boxboard. The inventive box comprises: adjacent portions having the same total surface area ash that of the rigid sides; a lateral flange which is fixed to the opposing adjacent portion, said sheet defining a tubular configuration, and—two flanges, namely an upper flange and a lower flange, which are used to fix the lids to the rest of the box in a permanent manner. The sides of the box opposite the aforementioned flanges are provided with holes which are used to mount pins, the ends of which are housed in holes in the inner parts of the lids, and said pins hold the lids in position when the box is closed.
