Abstract: A hermetically sealed pouch encloses both a porous mass of material of relatively low heat conductivity and a charge of a gas having a coefficient of thermal conductivity lower than that of air and thoroughly permeating the porous mass of material. The pouch is constructed of confronting sheets of multi-ply laminate material sealed along free edge portions thereof, and comprising an inwardly facing sealing layer of 15 pounds per ream low density polyethylene, a layer of 0.5 pounds per ream vinyl primer, a layer of 0.35 mil aluminum foil, a layer of 9 pounds per ream white low density polyethylene, and an outwardly facing layer of polymeric material selected from the group consisting of polyester and oriented polypropylene.

Abstract: A dispensing carton for relatively flat, rectangular articles comprises elongate side walls of generally rectangular disposition closed by end walls. Dimensions of the side walls are such that the articles in stacked array assume an angular disposition in the carton. An endmost article is presented at and partially protrudes through a dispensing slot provided in a side wall of the carton. Removal of the article through the slot permits the succeeding adjacent article to drop and tilt into position partially protruding through the slot.

Abstract: Cartons, folded from blanks and multi-component products, for example, a rigid container and a flexible pouch, are formed into a package wherein the container is separated from the pouch, without the use of partitions or compartments and wherein the container is positively secured against movement into or out of the carton. In one embodiment, the carton comprises an enclosing band which provides a particularly attractive surface for graphics and conveys a tamperproof feature to the package.

Abstract: Ink compositions suitable for ink jet printing on a variety of substrates and particularly food products, for example citrus fruit, and method of marking such products are provided. The compositions are characterized by their ability to penetrate the waxed surfaces of such foods as citrus fruits to provide markings therein. Preferred compositions comprise essentially a solution of a food dye or combination thereof, a binder resin component, a solvent mixture containing alcohol, water and an organic compound selected from the group consisting of aliphatic hydrocarbons having 5 to 12 carbon atoms and aliphatic ketones; and, optionally, an electrolyte.

Abstract: Ink compositions suitable for ink jet printing on a variety of substrates including metal, synthetic polymers and glass, are provided. The compositions are characterized by excellent weathering properties, are fade-resistant, abrasion-resistant and, when heated to temperatures of about 300.degree. F., exhibit resistance to aircraft hydraulic fluids. The preferred compositions comprise essentially a colorant or combinations thereof, an epoxy-phenolic binder resin component, a solvent mixture containing alcohol, water, methyl ethyl ketone or methyl cellosolve and, optionally, an electrolyte.

Abstract: A reclosable blister card package comprises a plastic blister having a flanged portion and a raised product holding portion. A paperboard card is releasably affixed to the flanged portion, and a portion of the card is folded over to present a folded edge extending over and engaging the flanged portion of the blister. A pair of parallel creases are provided in the paperboard card, one of which creases is disposed in substantial registry with the folded edge. Construction and arrangement is such that pivotation of the folded portion about the one crease away from the blister is effective to release the overlapped flanged portion from the folded edge and accommodate subsequent release of the card from the blister by pivotation of the card therefrom about the other crease.

Abstract: Binderless ink compositions suitable for use in jet printing operations on polymeric resin surfaces to form images which are highly resistant to abrasion and to steam pasteurization or sterilization conditions by penetration of the colorant into the sub-surface structure of the resin, are provided. The ink compositions are thermotropic, i.e. they change color in the presence of water or steam at elevated temperature and are useful as sterilization or pasteurization indicators. The preferred inks comprise either (1) a colorant which reacts under the sterilization conditions or (2) a combination of colorants one of which is extractible under sterilization conditions; a water and alcohol solvent system; a surfactant; an aliphatic or cyclic ketone, aldehyde, acetal, ether or ester and, optionally, an aliphatic hydrocarbon of 8-12 carbons.

Abstract: Binderless ink compositions suitable for use in jet printing operations on polymeric resin surfaces to form images which are highly resistant to abrasion and to steam pasteurization conditions by virtue of penetration of the colorant into the sub-surface structure of the resin, in contrast to conventional ink images secured on the surface of a substrate by binders incorporated in the ink composition. The preferred inks contain a basic or neutral dye, a water and alcohol solvent system, a surfactant, an aliphatic ketone or ester and, as a preferred optional agreement, an aliphatic hydrocarbon of 8-12 carbons.

Abstract: A premoistened wiper having high initial wet strength in a wetting liquid, and lower wet strength when immersed in substantially neutral water to allow for flushability. The wiper includes a nonwoven web of fibrous material which is bonded together by a polymeric adhesive binder, with the bonded web being moistened until the time of use by a wetting liquid having an acid pH level which is safe for external use on the human body. The binder is composed of a material which is highly adhesive in an acid pH liquid to bind the fibers of the web together, and which is further resistant to weakening over the relatively long periods of shelf life of the wiper. However, the binder loses its binding strength in substantially neutral or alkaline flush water to allow for flushability. The bonded wiper is maintained with wetting liquid thereon within a moisture sealed container until the time of use, and readily loses strength and disintegrates when disposed of in the substantially neutral water of a sewer system.

Abstract: An article is packaged in a multilayer flexible plastic sheet having a layer of a self-adhering plastic material and a layer of normally solid, thermoplastic organic polymer by (1) inserting the article between two opposing portions of the multilayer plastic sheet such that the layer of self-adhering plastic material faces the article; (2) collapsing the opposing portions into conforming contact with the article such that essentially all gases are permitted to pass out of the resulting package; and (3) sealing together the opposing contacting surfaces of said opposing portions to form a hermetically sealed package such that the self-adhering plastic material remains in clinging, conforming contact with the article and itself upon puncture of the multilayer plastic sheet.
