Abstract: Disclosed is a pressure foot designed to help maintain imbricated bags in a lined up relationship at the open mouth end of a dispensing container carton, as the bags are being dispensed from the open mouth end of the container carton, and a method therefor.

Abstract: Polymeric, oriented films can be made by the use of a combination of a hot blown process and a blown bubble process. Styrene butadiene copolymer (SBC) forms two outer layers of the preferred embodiment, with a core layer of very low density polyethylene (VLDPE) or blends thereof, and intermediate polymeric adhesive layers such as ethylene vinyl acetate copolymer (EVA) bonding the core layer to the outer layers. A monoaxially or biaxially oriented film is produced with excellent optics.

Abstract: Internal sizing ring assembly and method for its use on a stuffing horn to extract air from within a tube-like casing having a closed end during stuffing operations, includes a sizing ring having an inner mounting surface adapted to conform to the outer surface of the stuffing horn, a peripheral casing-expanding surface to expand the casing into an open configuration, and front and back surfaces; and vacuum means defined by at least one port extending through the sizing ring and a longitudinally extendable tube connected to the port and in cooperation with a vacuum source. The internal sizing ring assembly can further include a hollow mold having an internal cross-section configured to slidingly receive the sizing ring with the casing effectively sealed between the two for producing shaped products substantially free of air voids.

Abstract: A film with properties such as good thermal stability, enhanced extrudability, improved oxygen barrier properties, and reduced stickiness to metal surfaces is made by the use of a vinylidene chloride composition with small amounts of a plasticizer (such as epoxidized oil or epoxidized alpha olefin), and acrylate/styrene polymer (such as methyl methacrylate/butyl acrylate/styrene polymer) or poly(alpha-methylstyrene).

Abstract: An improved filling system for containers of mixtures of liquid and solid material where the liquid/solid ratio is critical is disclosed. A prior art problem was that sticky solid material would adhere to the receptacle or bucket in which it was delivered to a filling chute or funnel and it would also stick to the funnel. This problem is solved by putting the sticky solid in the buckets and by using the liquid to flush the funnel and by using an air jet to remove any remaining particles from the buckets which are upturned over the funnel. Alternately, a part of the liquid may be placed in the delivery bucket and when it is tilted or turned upside down to fill the container the remaining part of the liquid is used to rinse the receptacle. The filling system is especially useful for soups containing noodles or other pasta products.

Abstract: A forming web suitable for lining the interior of a rigid or simirigid container, such as a box made from corrugated board, includes an outer sealable layer; an interior barrier layer comprising a polymeric material with low oxygen transmission; a polymeric layer which adds bulk to the web; and an inner adherent layer. The web can also include polymeric adhesive layers for bonding the outer sealable layer to the interior layer, and the bulk layer to the interior and inner adherent layers respectively. More than one bulk or barrier can be included in the present invention.

Abstract: A flexible sheet material and bags made therefrom for packaging electrostatically sensitive items such as electronic circuit boards. The sheet has a metal layer and an antistatic layer. The outer surface of the bag has a high non-conductive surface resistivity greater than or equal to 10.sup.8 ohms/square, yet the bag protects the packaged item from static voltage by preventing the capacitive coupling of the voltage through the bag to the item packaged therein.

Abstract: The invention is a package comprising an outer plastic container, an inner plastic container, a product within the inner container, a liquid located in a space defined by the outer and inner containers, and a separating device located in said space.

Abstract: A flexible sheet material and bags made therefrom for packaging electrostatically sensitive items such as electronic circuit boards. The sheet has a metal layer that is adhesively laminated to an antistatic polymeric layer, the instant bag being of improved metal layer to antistatic layer adhesion. The metal outer surface of the bag has a high non-conductive surface resistivity greater than or equal to 10.sup.8 ohms/square, yet the bag protects the packaged item from static voltage by preventing the capacitive coupling of the voltage through the bag to the item packaged therein.

Abstract: An acid copolymer/quaternary amine mixture is disclosed which is permanently antistatic. The acid copolymer is a copolymer of (i) a major amount by mol % of an alpha-olefin of the formula RCH.dbd.CH.sub.2 wherein R is H or C.sub.1 to C.sub.8 alkyl, and (ii) a minor amount by mol % of an alpha,beta-ethylenically unsaturated carboxylic acid. The quaternary amine is of the formula [(R.sup.1)(R.sup.2)(R.sup.3)(R.sup.4)N].sup.+ [X].sup.- wherein R.sup.1 is selected from H, aryl, or C.sub.1 to C.sub.50 alkyl optionally having one or more non-contiguous C.dbd.O or NHC.dbd.O or --S-- or --O-- in the carbon chain, or the same as R.sup.2 ; each of R.sup.2, R.sup.3, and R.sup.4 is the same or different and selected from H, C.sub.1 to C.sub.18 alkyl optionally substituted with one or more OH or from --(R.sup.5 --O).sub.a --H where a is an integer from 1 to 10 and R.sup.5 is ethylene or propylene; and X is an anion selected from chloride, bromide, iodide, nitrate, fluoborate, phosphate, C.sub.1 to C.sub.

Abstract: A moisture sensitive film is produced by blending a copolyester with a moisture absorbing copolyamide, and extruding the blend either as a mono layer or multi layer construction. The blend material turns white when wetted. The invention has particular application in disposable diapers where a visual indication of wetness is desired.

Abstract: Apparatus for the opening of a bag 1 is provided with a clamp 2 having one fixed jaw 3 which applies a high pressure to a limited area of the bag by means of a pip 4, and a movable jaw 5 which applies a lower pressure to the bag 1 over a larger area through a spring-loaded block 6 and a rubber pad 7, and is movable by means of a pneumatic cylinder 8. The high pressure applied by the pip 4 is sufficient to prevent any relative movement of the bag panels. The lower pressure exerted by the rubber pad 7 is sufficient to prevent sliding movement of the pad 7 relative to the upper surface of the bag 1 but does not prevent relative movement between the upper and lower panels of the bag 1. When the movable jaw 5 is moved towards the fixed jaw 3 a region of the upper panel of the bag is buckled between the two jaws. Raising of the clamp thus opens the bag, the lower side being held down by adhesive tape 9.

Abstract: A plurality of corona-treated polymeric films, and metal foils or sheets, are alternately arranged and laminated together to form a laminate suitable for e.g. insulating panels. Construction of this absolute or near-absolute barrier can be simultaneous or sequential. The metal foils may be of the same type, or may differ. Aluminum and steel are preferred metal foils. At sufficient thicknesses, the sheet can be stamped or shaped. Both outermost surfaces of the laminate can comprise polymeric film, or both surfaces can comprise metal foils. Alternatively, one outer surface can be a polymeric film and the other outer surface can be a metal foil.
