Abstract: Systems, devices, and methods are described for providing a bag having an internally reinforced header. A reinforcing material is combined with a bag material to provide strength to the reinforced header. The reinforcing material and the bag material are aligned during manufacturing such that the reinforcing material is positioned in a header area of a bag formed by folding the bag material. A seal that passes through both the reinforcing material and the bag material retains the reinforcing material within the bag header. A bag handle may then be punched into the header through the bag material and the reinforcing material.

Abstract: A method for preparing a scored flexible structure that has utility in the construction of packaging structures, including steps of: (i) providing a structure as a web of flexible material; (ii) enhancing a thickness of the structure in a discrete region thereof by applying a substantially all-solids electron-beam-curable polymer material in fluid form onto the discrete region, the discrete region occupying a minor percentage of a total surface area of the structure; (iii) curing the polymer material by irradiating the polymer material with an electron beam, thereby forming an EB-cured polymer region; and (iv) forming a score line through a thickness of the EB-cured polymer region and through the thickness of the structure.

Abstract: Packaging containers (e.g., cups) or protective wraps may be made with two layers of sheet material and an expanded thermal insulation between the layers. The thermal insulation may be made from microencapsulated, heat-expandable particles that are expanded with a microwave heater at some point during processing substrate, building, conveying or packaging the containers. The particles may be applied to blanks formed from die cutting, expanded by heating, and then tampered. The blanks may be outer wraps to a double wall cup, formed by placing and adhering an inner cup to the outer wrap. Alternatively, an adhesive containing the particles are applied to inner cups, which may be adhered to outer wraps to complete formation of the double wall cups. The cups may then be heated with a microwave heater at a subsequent workstation as the cups are conveyed, stacked, placed in bags, the bags in cartons and the cartons stacked and palletized.

Abstract: Cups that color liquid contents and methods of manufacturing the same are disclosed herein. The cups include an inner wall with a colorant disposed and affixed therein. The colorant is predisposed (i.e., affixed) before the introduction of a liquid, and remains affixed until a liquid is introduced into the cup. The colorant can be disposed within a recess. The colorant can also be affixed to a first cup such that stacking an identical cup within the first cup does not result in the colorant touching the identical cup.

Abstract: An applicator article and method are disclosed for inserting a substance into a body cavity. The applicator article and method are especially useful for inserting a catamenial tampon into a woman's vagina.

Abstract: A multi-packaging device capable of carrying containers having a range of diameters. The multi-packaging device is constructed from a plastic sheet having an array of apertures arranged in lateral rows and longitudinal ranks. The plastic sheet contains integral segments of a resilient polymer coextruded with respect to the plastic sheet or laminated on the plastic sheet. The plastic sheet may also contain a longitudinally arranged line of weakness under the resilient polymer. The resultant structure enables the multi-packaging device to maintain integrity when a large diameter container is inserted into an aperture because the resilient polymer laminate continues to stretch even after the plastic sheet reaches a stress level approaching neck-down.

Abstract: An improved coated paperboard or plate stock useful for forming substantially rigid food containers such as plates, bowls, trays and the like and a process from producing the improved coated paperboard are provided. A base coat comprising a styrene acrylic latex and a pigment is applied directly to the paperboard, and a top coat comprising a styrene acrylic polymer latex and a pigment is applied directly to the base coat to form the coated plate stock. The improved coated plate stock is characterized by improved grease, oil and cut resistance, improved varnish gloss, enhanced smoothness, and improved printing quality.

Abstract: A gas barrier folding carton formed from a unitary paperboard blank (10) having a gas impermeable polymer layer (52) such as EVOH, nylon, or foil extruded on or laminated to one surface of the blank, except for certain adhesive (56, 58) coated areas. Two opposite side edges of the blank are seamed to form a flattened tube (13) having top and bottom closure flaps (30, 34, 36, 38, 40). One of the major closure flaps (36) at each top and bottom container end is provided with spaced abhesive areas (58), with areas of the two minor closure flaps (34, 38) also provided with abhesive (56). Upon folding the closure flaps at each end, the folding sequence pulls the barrier film (52) away from the abhesive (56, 58) areas and subsequent heat sealing produces hermetic sealing of the carton. This process and carton construction may be employed with conventional gas purging of the container interior by an inert gas before final sealing.

Abstract: A tamperproof bag is provided with closure means comprising a strip of microcapsules containing an adhesive core enclosed by a shell adapted to be broken by pressure application to release the adhesive contents. The microcapsules are applied to the bag by means of a binder system or by depositing them onto an adhesive tie-coat previously applied to the bag.
