Abstract: An end load carton includes a closure system having a tab constituting part of a control region which is spaced from a free edge of an upper flap of the carton by a support region. The control region also includes a press zone adjacent the tab. After initially opening a top portion of the carton by releasing an adhesive connection between the upper flap and a lower flap, the tab can be positioned in a slot formed in the lower flap to reclose the carton. More specifically, the upper and lower flaps can be selectively interconnected through the closure system by pushing on the press zone to depress the upper and lower flaps in order to open up the slot and align the tab with the slot. To reopen the carton, the support region can be readily grasped and pulled to open carton without fear of tearing the upper flap.

Abstract: A paper structure is disclosed, which comprises: a paper substrate; an adhesive layer, formed on the paper substrate; and a polymer layer; wherein the polymer layer is configured with a plurality of embossed elements and is disposed on the adhesive layer for allowing the spaces formed between the embossed structures and the paper substrate to be filled by the adhesive layer. In addition, the flexibility of a carton box that is formed using the aforesaid paper structure can be enhanced through the cooperation between the embossed structures and the adhesive layer filled inside the recesses of the embossed structures, and thus the ability of the carton box to absorb collision impact can be improved.

Abstract: A package of flexible material, particularly suitable to contain sterilizable food products, has a parallelepiped box shape with a base or bottom wall (2), a top wall (3), a front wall (4), a back wall (5) and two side walls (6, 7), an opening (8) closed by a peelable patch (9) sealed along a track (20) disposed astride the peripheral edge of the opening (8) being provided on the top wall (3), a respective peripheral edge (10) protruding from the base (2) and from the top wall (3).

Abstract: A blank, carton, or package including a handle formed in a top panel is described. Deformation lines can be included on the blank or carton to allow the handle to flex, thereby increasing handle strength. The blank can include corner-forming panels attached to end flaps that can be used to form corners in the formed carton or package. The corners provide reinforcement strength to allow stacking of the cartons or packages, such as on pallets or during shipment. Openings can be provided in select areas of the blank, carton, or package to allow ventilation to and from the interior of the carton or package. Connecting panels in the top panel can be removed to dispense articles from the carton or package.

Abstract: Readily sealable containers which do not require the moistening of dry adhesive layers or the use of removable release liners to protect pressure sensitive adhesive layers. Although the containers may have many applications and uses, they have particular advantages for shipping and mailing purposes. Thus, envelopes and shipping boxes are notable embodiment examples. In general terms, two facing sections of the container have layers of an adhesive substance and a release substance, arranged in such a manner that when the two facing sections are in contact with one another, the adhesive substance layers face the release substance, preventing a permanent sealing of the container, and then, the positioning of another section of the container, free of any adhesive or release substance between the two facing sections, which causes the sealing of the container.

Abstract: One aspect of the present invention is a packaging material having a abhesive for preventing the adherence of the interior surfaces of the packaging material during application of a closure thereto. One example is a carton blank having the closure attached prior to erection of the blank on a packaging machine. Another example is a, roll of packaging material such as used to fabricate a TETRA BRIK® parallelepiped package on a vertical form, fill and seal machine. Another aspect of the invention is a method for applying a closure to such a packaging material. Yet another aspect of the present invention is an apparatus for applying closures to such packaging material. The abhesive may be a coating, printing, strip or an embossment of the material.

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.

Abstract: A carton blank comprising a relatively rigid material having an inner surface, having a central body portion and opposite edge portions and wherein a relatively flexible material, preferably fluid impervious, having a central body portion and opposite edge portions has its central body portion secured to the central body portion of the relatively rigid material and the opposite edge portions of the relatively rigid material and the relatively flexible material are not secured to each other. In some instances strips of another relatively flexible material are secured to the opposite edge portions of the relatively flexible material but are not secured to the opposite edge portions of the reactively rigid material. In other instances, a plurality of spaced apart strips of a relatively flexible material are superposed over portions of a relatively rigid material and a plastic coating is applied to the exposed surfaces thereof.

Abstract: A carton blank formed from a laminate of a relatively flexible fluid impervious material and a relatively rigid paperboard material is provided with paperboard to paperboard facing surfaces so that an effective seal can be formed.

Abstract: A method for packaging a product includes the steps of providing a composite film including a non-barrier layer and a peelable barrier layer; providing a bottom web having the product supported thereon; removing a strip of the non-barrier layer from an edge of the composite film so as to provide an extending portion of the barrier layer which extends beyond the non-barrier layer; and sealing the composite film over the product to the bottom web so that the non-barrier layer overwraps the product and is sealed to the bottom web wherein the extending portion of the barrier layer forms a pull tab for peeling the barrier layer from the non-barrier layer.

Abstract: The present invention provides an easily openable sealed container consisting of a lid and a main body having a flange, wherein a sealing layer of the main body or a sealing layer of the lid has a number of microdents in the flange portion, the thickness of said sealing layer is 10-1000 .mu., said sealing layer and an adjacent layer contacting therewith have a lamination strength of 300-2,000 g/25 mm width, and said sealing layer and the lid or the main body are sealed in the flange portion at a strength larger than said lamination strength, as well as a process for producing said sealed container.
