Abstract: A bag for holding a generally circular product formed by two sheets of material which are joined along the side and bottom edges thereof leaving the top edges open to accept the product. The bottom corners of the bag are curved and a flap is attached to one of the sheets along its top edge with curved seams so that when the flap is folded over, the corners at the top edges are also curved. In one embodiment, the flap is generally rectangular and is also attached to said one sheet in areas outside of the curved seams.

Abstract: A laminated wrapping sheet material comprising a layer of paper bonded to a layer of thermoplastic film, is formed such that a layer of paper of 15-35 gsm gauge is discontinuously bonded to a layer of thermoplastic film of 8-35 microns such that pockets of air are defined between the layers.The sheet material is useful in the construction of a captive flap bag formed of a paper-thermoplastic film laminate and comprising two superimposed walls with thermoplastic film on the inside, closed at the bottom and on each of the two side edges, and open at the top edge, at least one wall having a reflex internal flap along the top edge sealed at each of the side edges, to define an internal inverted pocket, the two walls not being sealed to each other in the region of the pocket or pockets.

Abstract: A roll dispenser 1, preferably one piece having no moving parts, has a rear aperture 8 for insertion of a roll and a front aperture 7 for extraction of material from the roll. A cutter 2 is provided adjacent to the front aperture 7 and a cling surface 3 close to the cutter ensures proper disposition of the material during the retraction. The dispenser is conveniently made by injection moulding, or by compression moulding in which case it is desirable that the top surface 11 and bottom surface 12 are mutually parallel.
