Abstract: A method for the manufacture of a flexible container suitable for use as a water bed for livestock comprises providing a first layer of a flexible polymeric material, applying a mask insert to an inner zone of a first surface of the first layer, the mask insert being arranged spaced from edges of the first layer thereby to define a substantially continuous boundary zone, arranging a second layer of flexible polymeric material to lie adjacent the first layer with the mask insert sandwiched therebetween, and subjecting the assembly so formed to a treatment operation thereby to form a face to face seal between the boundary zone and the confronting surface region of the second layer.
Abstract: A bag for packaging liquid formed using plastic in film form is disclosed. The bag includes a leaktight chamber for liquid and a pocket, adjacent to the chamber, in which a pipe for withdrawing the liquid is housed. Access is provided to the inside of said pocket. An opening is formed through part of the wall of the pocket, adjacent to the chamber, to allow the withdrawing pipe to enter the chamber in a leaktight fashion. The opening is situated at the end of a tubular element of decreasing section, at the place where the section is the smallest with the element being formed from a film of plastic forming one wall of the pocket adjacent to the chamber. The tubular element accommodates the pipe for withdrawing the liquid from the chamber and is at least equal to that of the opening, so that the tubular element forms a seal around the withdrawing pipe.
Abstract: A process produces a tubular body with at least one dividing wall extending across its length and forming longitudinal chambers disposed next to each other. A foil strip is used whereby a dividing-wall strip or a section of dividing-wall strip is cut to length and is fastened at its lateral outer edges on the foil strip or section of the foil strip, with parallel alignment with the foil strip or section of foil strip. The lateral edges of the foil strip or section of foil strip are then joined with each other thereby either directly forming a tubular body or forming an endless tube, from which tubular bodies are then cut to length. The tube is then solidly joined with a tube head having a dividing bridge conforming to the arrangement of the dividing wall in the tubular body. The tube head has a dispensing aperture closable by a closure.
Abstract: A multiple compartment package having a connecting bridge with a frangible internal barrier is made from two composite or thermoplastic sheets or webs welded together to form the front and back walls of the package, and the central bridge portion is defined by one or more partitions spanning the short distance between the webs. In the preferred embodiment, multiple partitions form a plurality of parallel compartment strips to create an obstruction to penetration of substances from one packet to the other. One process for making the invention uses a comb-shaped mask and a thermoplastic insert strip interwoven between the tines of the comb. The tines are extended down between the welding heads of the packaging machine, preventing welding from taking place between the thermoplastic sheets wherever the comb mash is, with the result that the welding occurs between the strip and an alternating one of the side webs creating a zig-zag pattern that forms the vacant barrier compartments.

Abstract: A card display pocket formed of three sheets of fusible material. The first sheet is a nylon/vinyl material that is slit one way to receive the second sheet of a frosty vinyl material which may be slit a different way from the first sheet to form specially designed pockets and woven through the first sheet of material, over the front side of the first sheet of material and under the back side of the first sheet of material. The third sheet is a plain vinyl that is used for a backing.The method of construction is as follows: In a sheet of nylon/vinyl material slits are made lengthwise or widthwise through the material so that they are either generally parallel to each other or generally perpendicular to each other. Translucent vinyl material, is then interwoven through these slits in order to form the desired pockets. The card pocket with curved sides is especially desirable for applications where a card is frequently accessed.
Abstract: A double zipper pouch having first and second pockets adjacent one another and with a common wall portion, each pocket having an opening for receiving contents such as identification papers. The first and second pockets are formed so that their openings are displaced relative to one another. Pressure actuated resealable fasteners are disposed adjacent the openings in each of the first and second pockets. First and second indicators are also disposed adjacent the openings to provide an indication of the location of the associated opening. The indicators are preferably different from one another so as to provide an identification for the associated pocket. An adhesive material is formed on the back of the first pocket for affixing the pouch to, for example, a package.
