  • Patent number: 9714112
    Abstract: The sealing device for a paper-based container has an elongated release base member with a double-sided adhesive layer on a major side along the length of the release base member. The release base member is adhered to a front portion of a flap of the container by the double-sided adhesive layer so that the flap may be used to seal the container. To open the container, a pull strip of the release base member is pulled off and the flap is separated. To reuse the container, a second sealing device is applied to another flap of the container so that the container may be reused.

  • Patent number: 6527168
    Abstract: Blanks for forming open sided containers and mating covers from carton stock material include strips of non-stick material secured to the blank by means of a strippable adhesive. The adhesive adheres to the carton stock material with a substantially higher adherence force than the adherence force between the adhesive and the non-stick material, so that the non-stick material can be removed, readily, to expose the tacky surface of the adhesive. The carton blanks are marked with a predetermined pattern of fold or crease lines which allows the blank to be bent and folded into the shape of a container or a container cover. The non-stick material facilitates handling and separation of individual blanks that have been shipped and stored in tightly packed, stacked arrays, while the exposed adhesive surface engages specifically formed tabs and/or flaps of the blank in overlapping, abutting relationships to secure the blank in its final, assembled, container/cover shape.

    Abstract: A method of creating a package with reclosable resealable flaps. The package is defined by a blank formed by die cutting a continuous web or sheet of material after ink and a release coating have been applied to one side of the web but on different areas. The blank, when folded, provides a structure with a rectangular cross-section having four planar sides, each side with extending flaps. A package is formed by closing and securing the flaps on the bottom end of the structure using a permanent adhesive. The package is then filled with product. One top outer flap can have a release coating applied to an area which will be engaged by the opposite flap when closed. This release coating, in combination with a repositionable adhesive, will cause the opposed flaps to releasably adhere one another to secure and seal the top opening. Repositionable adhesive can also be applied, either to the release coating itself, or to the surface opposite the release coating to the seal.

In a preferred embodiment there is at least one lower flap with at least one recessed area, at least one seal flap with at least one aperture and at least one top flap. The lower flaps are folded inward followed by the seal flap. An adhesive is on the inner surface of the top flap which then is folded inward onto the seal flap. The adhesive flows through the at least one aperture in the seal flap and spreads outwardly in the at lest one recessed area below the at least one seal flap to become anchored to the seal flap. This is enchanted by a plurality of recesses in the at least one lower flap adjacent to the at least one aperture in the at least one seal flap. By being anchored to the seal flap and adhesively attached to the fiberboard underside of the top flap, a strong end seal is formed on the carton.

    Abstract: A sift proof carton and method of folding and sealing the major and minor end flaps of a carton to provide a sift proof container wherein the method includes providing a carton having first and second inside and outside major flaps and a pair of minor flaps, and folding the minor flaps to substantially cover an open end of the carton. Opposite sides of the first inside major flap are then mitered and both the first and second major flaps are positioned in open positions with respect to the carton. The carton is then put in motion and, during such motion, an adhesive pattern is applied from a stationary adhesive nozzle member to selected areas of the second outside major flap and the minor flaps. The first inside major flap is then folded onto the minor flaps followed by the second outside major flap which provides direct sealing contact between the second outside major flap and both minor flaps as well as portions of the first inside major flap so as to provide the sift proof carton.

  • Patent number: 5234160
    Abstract: An aseptic pour spout seal for a flat top end closure having two oppositely disposed outer closure panels, and two oppositely disposed fold-in panels, one of which serves as the pour spout when opened. Each of the fold-in panels includes a substantially triangular panel portion, and a pair of fold-back panels integrally connected to and folded between the substantially triangular panel portion and the respective adjacent outer closure panels. Diagonal opening-assist score lines are formed on the outer closure panels adjacent the respective fold-back panels. An abhesive release coating is applied to the outside surfaces of the pour spout, and to the inside surfaces of either the pair of fold-back pour panels or the adjacent areas defined by the diagonal opening-assist score lines. A suitable sealant is overlain on the abhesive release coating on the pair of fold-back pour panels or the adjacent areas.

  • Patent number: 5018660
    Abstract: A liquid carrying, thermoplastic coated paperboard container including a top end closure, a four-sided body portion, and a bottom end closure, wherein various end closure panels are folded so as to abut against one another to become sealed thereagainst. To effectuate the sealing, a pressure sensitive, food grade adhesive is applied to at least one of each two abutting surfaces and the abutting surfaces are pressed together without the application of heat or high frequency vibration. The adhesive may be applied to the blank during the converting process, or while the blank is being formed into a container on the forming, filling and sealing machine.

  • Patent number: 5016812
    Abstract: The invention relates to a high-integrity closure, sift-proof carton [10], a method and an adhesive dispensing apparatus for producing same. Foamed hot melt adhesive is dispensed in parallel strips from dispensing guns onto the flaps [20], [22], [30], [32] of the carton [10], which are thereafter folded down to close the carton [10]. The strips can be spaced so that a continuous tight adhesive seal is formed, especially by providing a strip pattern interdigitating when the flaps contact each other. Since all strips are provided in parallel, while the carton is moved with respect to the dispensing apparatus, application of adhesive is fast and reliable.

  • Patent number: 4746061
    Abstract: A corrugated cardboard carton has opposed foldable outer flaps associated with the top and bottom ends thereof which overlap inner flaps in a conventional manner, with the opposed outer flaps being sealed together adjacent their free edges. To create a tamper-resistant seal between the outer flaps, the flaps terminate in free edges which effectively abut when the carton is closed, which free edges are defined by the inner facing layer and the intermediate corrugated layer of the board stock defining the flaps. The outer facing layer of the board stock defining the flaps is provided with a securing strip which is integral therewith and which projects outwardly beyond the free edge. This securing strip has cuts or openings therethrough. The outer facing layer of the flap also has an indicator strip, preferably of a bright color, formed on the exterior face thereof.
