Publication number: 20110245056Abstract: Apparatus and method for affixing rigid transparent windows to folding cartons draws rigid window web material from a roll and scores and notches the window material in a continuous manner. Notch waste is removed and collected for disposal by the combination of vacuum and an air jet applied at the point of severance. The transparent window material is then provided to an accumulator and then to a stop-and-go adhesive application and material cutting stage, where adhesive is applied to the material which is cut into individual rigid window patches, with the accumulator serving as a buffer between the high speed continuous scoring and notching stage and the stop-and-go adhesive application and cutting stage. Adhesive-bearing individual window patches are applied to moving folding cartons with registration between the notches and cut lines as well as between the cut window blanks and carton blanks provided by a control system.Type: ApplicationFiled: March 31, 2010Publication date: October 6, 2011Applicant: Tamarack Products, Inc.Inventors: David E.

Publication number: 20100105534Abstract: A display pack for a consumer product is made of two sheets of corrugated cardboard and a clear plastic container with a flat insertion portion sandwiched between the cardboard sheets. The two cardboard sheets are adhered together in a peripheral area of the package by a heat-sensitive adhesive, and the corrugations of the cardboard sheets are crushed and flattened in the peripheral area. To seal the package, the peripheral area of the two cardboard sheets is subject to sufficient pressure to crush the corrugations inside the cardboard sheets and flatten them in that area. Heat is applied to the outer side of the cardboard sheets in the peripheral area and conducted to the adhesive material between the two sheets to activate the adhesive material. A sealer machine with a heated sealing press or parallel sets of heated rollers may be used to carry out the sealing process.Type: ApplicationFiled: January 5, 2010Publication date: April 29, 2010Inventor: Joseph Nazari

Patent number: 5060852Abstract: A box having a cover with a plurality of windows and at least a majority of the windows being elongated and oriented in generally spaced relationship with respect to each other. Each window is defined at least in part by a pair of spaced window defining sides. A first or leading series of such window defining sides is disposed in non-parallel relationship with each of a second or trailing series of window defining sides. This serves to facilitate manufacture of boxes from blanks that are readily movable over each other without undesirable edge-to-edge continuous contact which inhibits relative sliding movement during manufacture. The non-parallel window defining sides may be inwardly concave or have each window defined in part by a pair of straight window defining sides which diverge. An associated method for establishing container blanks of this type is disclosed.Type: GrantFiled: March 8, 1990Date of Patent: October 29, 1991Assignee: Package Products, Inc.Inventors: Alan Beckerman, Beth A. Brady

Patent number: 5060853Abstract: A package comprising a consumable product and a sealed container containing the consumable product. The container is made up of a folded and sealed sheet of carton material having an opening therein defining a product-viewing window and a sheet of clear film material disposed over the opening so as to close the opening while retaining the product-viewing capability of the window . The clear film sheet has a marginal periphery disposed in lapped relation to a marginal periphery of the carton sheet and a wave energy curable adhesive between the marginal periphery of the clear film sheet and the marginal periphery of the carton sheet in a cured by wave energy condition bonding the clear film sheet over the carton sheet opening so that the bond cannot be rebounded by the cured adhesive once the bond provided by the cured adhesive between the sheets has been broken. The container is erected from a flat blank consisting of the carton sheet, the film sheet and the cured adhesive.Type: GrantFiled: July 19, 1990Date of Patent: October 29, 1991Assignee: Gulf States Paper CorporationInventors: Richard F.

Patent number: 4247349Abstract: Panels of plastic film are delivered to a perforated vacuum drum which has a knife edged die mounted on its surface. Each panel is laid over the die and rotates with the drum into rolling contact with an anvil roll which firmly presses the film panel against the knife edge to cut the panel. After cutting, the film panel continues to rotate with the drum to a position wherein it registers with a blank having a cut-out opening therein which is covered by the film panel. The areas of the blank surrounding the cut-out opening are covered with an adhesive material which causes the film panel to remain adhered to the blank. The vacuum drum continues to rotate and, after bonding of the panel to the blank, the drum releases the vacuum draw on the panel. The cuts formed in the plastic film panels can be straight lines, lines of perforations, or cut-outs bounding areas which are removed from the panel.Type: GrantFiled: May 14, 1979Date of Patent: January 27, 1981Assignee: American Can CompanyInventors: Robert M.
