Abstract: A method of attaching two containers wherein a releasable attachment insert is placed during assembly between the side walls and side flaps at each end of two containers faced toward each other, and the dual container structure formed thereby. The insert acts to securely attach the two containers such that they may easily be separated for later sale as independent units.

Abstract: A dual carton formed from two substantially identical single cartons adhered to one another with adhesive which remains tacky after the cartons are separated. Each carton has a top and tuck-in flap, and the flaps of the two joined cartons are overlapped to seal the dual carton. The tuck-in portion of the flap of one carton is adhered to the top portion of the flap of the other carton with similar adhesive as used to join the cartons. After the cartons are separated, the cartons may be individually sealed by reusing the adhesive on the wall of one carton and on the tuck-in portion of the flap of the other carton to adhere the tuck-in portion of the flaps of the cartons to the outside of the wall opposite the wall from which the flaps extend. The dual carton may be a cigarette carton of dimensions compatible with tax-stamping machinery and temporarily sealed in such a manner as to facilitate the opening and later resealing of the carton for tax-stamping purposes.

Abstract: An apparatus and method for taping closed the open edge of a composite newspaper is provided which includes a tape applicator for applying a portion of tape to one side of a newspaper, and a moving member presenting a surface moving downstream with the newspaper but at a greater speed relative thereto, whereby a remainder portion of the tape not adhered to the one side may be wrapped around the open end by temporarily adhering a portion of the remainder of the tape to the moving surface and transferring the tape thus temporarily adhered from the moving surface to the other side of the newspaper as the moving surface passes thereby in close adjacency.

Abstract: A receptacle for food products and the like is provided. A plastic film is tightly wrapped about a preformed package such as a tray containing wet food products. The film defines a pair of opposing flaps and an area of overlapping film portions extending between the flaps and adjacent to the bottom surface of the tray. Heat and pressure are applied to the wrapping at the bottom surface of the tray to provide a flat, sealed film surface. A strip of adhesive tape is applied to the flat film surface, thereby connecting the opposing flaps and providing a seal over the seam defined by the overlapping film portions. The tape is then heated to cause the adhesive to flow, thereby improving the seal. The wrapping is prevented from moving from its original position by the tape and is accordingly substantially leak-proof.

Abstract: A holder for flaps of corrugated cartons is designed to temporarily hold carton flaps either in the fully opened position, for loading or unloading, or in a temporarily closed position. The device acts as a clip, with two flanges between which one or two layers of corrugated board may be engaged. The clip preferably is formed of one integral piece, with one flange being substantially the size of a large central opening in the other flange. The inner flange may have a rest position which extends slightly through the opening of the outer flange, so that the clip always tends to spring back to this position and will exert a clamping force on the carton flaps.

Abstract: A disposable elongated material engaging member, formed from reasonably stiff and yet deformable material, is placed adjacent one side of units on a pallet at a wrapping station with the material engaging member having protruding portions oriented to extend in a direction away from the surface of the units for engagement with the netting material as the netting material is wrapped around the units. A forming and feeder mechanism, receiving a continuous supply of the reasonably stiff material, forms the material engaging member into the desired configuration and shape, and then dispenses the thus formed member into the wrapping station where the formed member is severed from the continuous supply by the forming and feeder mechanism after the formed material at the wrapping station has been contacted by a plurality of wrapped layers of the netting material.

Abstract: A pellet wrapper adapted to wrap a pallet with a web material comprises, an anvil member movable into position against the side of the pallet, a clamp movable with the anvil and adapted to hold the end of the web with which the pallet is to be wrapped. With the clamp and anvil so positioned adjacent the pallet, the wrapping of the pallet is begun. After the web has wrapped around the pallet at least sufficient turns so that the web overlies the end retained in the clamp and secures this end portion against the side of the pallet, the clamp is then released and retracted and the wrapping of the pallet completed to wrap the pallet and then back to overlapping the layer of web material initially applied to the pallet while forming said web in about the last 11/4 turns into roped form.

Abstract: A method and apparatus are provided by which bag forming material is obtained by feeding sheet material (2) together with male and female closure elements (5, 6) to a nip between guide roller (3) and pressure rollers (9, 10) at which adhesive is applied from nozzles (11, 12). The resulting material assembly is fed by drive roller means (14, 15)to an accumulator (16) on a continuous basis and then intermittently over a forming shoulder (21) into a tubular form (22) while maintaining the closure elements (5, 6) at a predetermined distance apart before the forming shoulder (21) by means such as grooves (19) in guide roller (18) and locating the closure elements (5, 6) in predetermined positions facing each other downstream of the shaping shoulder by suitable means (23) which may include rotatable guide elements. The tubular form (22) is drawn through the apparatus by transverse reciprocating sealing bars (26) and a pilfer proof closure can be provided by vertical sealing bars (25).
