  • Publication number: 20120132698
    Abstract: An assembly including a front panel is separated from a back panel by a panel fold line. Side flaps are disposed at opposing edges of the front panel and are each separated from the front panel by a flap fold line. The side flaps include a front flap surface with an adhesive material and a back flap surface opposite the front flap surface. The assembly is foldable about the panel fold line to dispose the back panel adjacent the front panel and foldable about the flap fold line to dispose the back flap surface adjacent a front surface of the back panel when the back panel is folded. In a folded position, the assembly forms a pocket between the front and back panels, and is adherable by the adhesive material to a separate surface.

  • Patent number: 7744517
    Abstract: A tamper indicating, resealable closure for a package includes first and second film layers releasably adhesively joined together such that the first and second film layers are at least partially separable when the second film layer is pulled away from the first film layer. The first film layer includes first and second tear lines formed thereon to define first and second panel sections respectively. The first panel section defines an access opening through the first film layer when it is separated along the first tear line during an initial separation of the first and second film layers. The second panel section also becomes separated from the first film layer when the second film layer is separated from the first film layer to provide an indication of an initial opening of the closure. Subsequently, the second film layer may be re-adhered to the first film layer to reseal the access opening, while the second panel section remains separated from the first film layer.

  • Patent number: 7416521
    Abstract: An apparatus and method for making a composite packaging material for easy-open packages includes means for pulling a running length of packaging film, the film having defined rupture characteristics. The packaging film is perforated with a sequence of spaced apart at least one perforation separated from another at a substantially constant fixed interval between adjacent ones of the sequence along the length of the film. A tape with a continuously extending dry edge is formed from a continuous supply of tape and tape pieces are formed and spaced apart along the length of the film. Successive discrete pieces of tape are adhered to the packaging film in overlying sealing relationship to successive ones of the sequence of at least one perforation.

  • Patent number: 7118520
    Abstract: A method of producing an adhesively closable data disk holder having of a pair of heat-sealable plastic panels fused together to form an interior pocket with an opening thereto, wherein an additional adhesive layer is fused to the inner surface of one of the holder panels adjacent the opening thereof to facilitate adhesive closure of the opening without the use of an overlying flap. The adhesive layer is constructed of a thin panel of compatibly heat-sealable plastic material, one surface of which carries a pressure sensitive adhesive over which an adhesive release strip is disposed. The adhesive layer is disposed between the outer holder panels so that the adhesive release strip insulates against fusion to its adjacent panel, as the opposing non-adhesive surface of the adhesive layer is heat-sealed to its adjacent holder panel. The process results in a data disk holder having a substantially uniform thickness throughout which is particularly beneficial when used in a bindery process.

  • Patent number: 6821239
    Abstract: A tamper evident hinge type closure includes, as is conventional in such closures, a body portion, a lid portion and a hinge portion. Advantageously, at least one tamper evident band is provided so as to mechanically secure the lid portion to the body portion at a position that is distal from the hinge. The tamper evident band, which is designed to break upon initial opening of the closure by a consumer, is preferably integral with both the body portion and the lid portion, so as to ensure more reliably than was possible with interlocking mechanical tamper evident structures that the closure may not be opened without defeating the tamper evident band. A process for making the improved closures is also disclosed.

    Abstract: A first embodiment of the packing film is a four-layered laminate film in which the following films are laminated in that order: a first oriented plastic film formed as an outer surface layer and provided with a first coarse surface portion, an aluminum foil or paper sheet, a second oriented plastic film provided with a second coarse surface portion which is overlapped with the first coarse portion, and a non-oriented plastic film formed as an inner surface layer. A second embodiment of the packing film is a three-layered laminate film in which the following films are laminated in that order: an oriented plastic film formed as a first surface layer and provided with a coarse surface portion, an aluminum foil, and a non-oriented plastic film formed as an inner surface layer. The oriented plastic film forming the outer surface layer is backed at its coarse surface portion by a thin surface layer and laminated to the aluminum foil through a binder layer.

  • Patent number: 5203935
    Abstract: A teartape for packaging materials, and particularly such materials based on polyolefin films, includes a base film coated with a pressure sensitive adhesive composition. The teartape is affixed to the packaging material by the adhesive composition. This avoids the problem of distortion which can occur when affixing conventional teartapes to such packaging materials by means of hot melt wax compositions. The teartape is applied to moving packaging material by controlling the speed of the teartape in accordance with the speed of the packaging material so as to reduce tension imbalance. The speed of the teartape may be controlled in dependence upon the tension in the teartape. This can be achieved by supplying the teartape from a dispenser having a brake means (4,5) and a drive means (10,11,12) for regulating the speed of the teartape in dependence on the tension in the teartape.

  • Patent number: 4634008
    Abstract: To facilitate manual opening of a container made out of a flat material like paper, cardboard, etc. with a ridged-seam closure, and especially a parallelepipedal container for liquid and made out of paper, plastic, or composite, at least one tear-off flap is attached to the outside of the ridged-seam closure like a tab. To facilitate in particular the opening of containers with earfolds, perforations are provided in the vicinity of the triangular folds to generate a smooth tear when the container is opened and produce a clean opening that will ensure trouble-free pouring.
