A vent hole may be formed through the body wall and the label by way of a laser for allowing the passage of air therethrough. The flexible liner is secured to the respective ends of the tubular body wall by way of an adhesive band between the liner and the inner surface of the tubular body wall.

Abstract: A cut-off apparatus for non-circular tubes includes an axially movable carriage supporting one or more cutter assemblies and a drive system for driving the carriage synchronously with an advancing tubes. The advancing tube is received over a cutting mandrel mounted for movement with the carriage. The one or more cutter assemblies are disposed within the mandrel and comprise radially movable knives that are extended outward so as to cut the tube from the inside. The knives are urged radially outwardly by a cam moved by a control rod disposed within the mandrel. A clamp assembly is mounted on the carriage radially outwardly of the tube aligned with a cutter assembly, and includes clamp members that move inwardly to clamp the tube from the outside to restrain the tube against radially outward movement when being cut.

Abstract: An improved plunger for a lithographic printing ink cartridge prevents air entrapment between the plunger and the ink when the plunger is pressed into the ink during cartridge assembly. The plunger bottom portion has a positive radius and a textured surface that facilitates the flow of air away from the center of the plunger toward the cartridge sidewall as the plunger is pressed into the ink.

Abstract: A shipping package for protecting a fragile item such as a sample vial comprises a crush-resistant inner container comprising a tube formed from spirally wound fibrous plies adhered together, and an outer container surrounding the inner container. The outer container comprises a semi-rigid can formed of fluid-impervious, flexible polymer and having a receptacle portion and a closure portion releasably fastenable to the receptacle portion so as to render the outer container substantially impervious to fluid outside the outer container. The inner container preferably has a liner of absorbent material. The outer container preferably is formed of polyethylene teraphthalate. The receptacle and closure portions of the outer container preferably are threaded so that the closure portion is screwed onto the receptacle portion.

Abstract: A composite can having improved “green” strength is made by pattern printing adhesive onto the exterior label or cover such that the adhesive covers less than 100 percent of the surface of the label. The total amount of adhesive applied between the label and the paperboard body wall is thereby reduced, so that less moisture is added on to the paperboard relative to conventional can-making processes in which adhesive is flooded onto the entire surface of the label. A preferred embodiment of the invention comprises an easy-open can, such as a dough can, having the adhesive applied with relatively denser coverage on the portion of the label that overlies the spiral butt joint that is formed between edges of the spirally wound paperboard body ply, and with relatively less dense coverage on other portions of the label.

Abstract: A tubular or ring-shaped core for winding pressure-sensitive tape has a paper board body and a release-coated outermost ply formed of a strip of polymer film having a release coating on its outer surface and a tacky adhesive layer on its inner surface. The strip is wound onto the core with one edge of the strip folded outwardly away from the core so as to expose the tacky adhesive layer on the folded edge. This folded edge is overlapped by the opposite edge of the strip, thereby placing the tacky adhesive layers on the two edges in contact with each other. A firm bond between the overlapping edges is achieved by the adhesive-to-adhesive contact. In a preferred embodiment, the overlapping edge of the strip overlaps slightly beyond the folded edge onto the unfolded outer surface of the strip. This unfolded portion is treated to promote adhesion of the overlapping edge thereto.

Abstract: A film bag is disclosed for containing articles, such as candies, food and other items. The film bag is made from a laminate that includes an inner layer and an outer layer with printed indicia formed on it. The outer layer includes a fixed portion which is attached to the inner layer with a permanent adhesive. The outer layer also includes a removable sticker portion which is substantially coplanar with the fixed portion. The removable sticker portion is attached to the inner layer with a pressure sensitive adhesive. Preferably, at least part of the pressure sensitive adhesive on the removable portion is separated from the permanent adhesive on the fixed portion by a gap.

Abstract: A container having a window for viewing the product contained therein and an associated method of manufacture is provided. The container is constructed of at least one body ply and a liner ply. The body ply defines at least one aperture therethrough such that when the body ply is wrapped into a tubular shape the aperture forms a window through the body ply into the container. The liner ply extends across the aperture in the body ply and has a sufficiently low opacity that allows the product in the container to be viewed through the window. The liner ply provides a moisture and gas barrier inside the container around the product. The container may include a label ply. The label ply defines at least one aperture therethrough. The cutting of the at least one aperture in the label ply is registered. The body ply defines at least one aperture therethrough corresponding to the at least one aperture in the label ply.

Abstract: A Clearview packaging assembly for containing an irregular shaped appliance such as a washer or dryer is provided. The assembly comprises a clamshell-like framework placed around the appliance and wrapped tightly in transparent film. The framework includes a hinged top cap, front corner posts glued to the front portion of the top cap, rear corner posts glued to the rear portion of the top cap, front and rear bottom pieces glued to the lower ends of the corner posts, and a basiloid piece glued to the two rear corner posts. The top cap and the basiloid piece cooperate to form a three-layer thick basiloid handling flange to facilitate basiloid lifting of the packaging assembly with the appliance contained therein. The top cap has triangular shaped side walls that, along with the front corner posts, maintain the structural integrity of the package and prevent trapezoiding during basiloid handling.

Abstract: A multi-ply tubular container for products is provided having a first ply wrapped into a tubular shape and having an inner surface and a second ply wrapped into a tubular shape and having an outer surface positioned in face-to-face contact with the inner surface of the first ply. At least one of the first and second plies is a body ply formed of fibrous paperboard. A foamed adhesive is placed between the inner surface of the first ply and the outer surface of the second ply. The foamed adhesive reduces moisture contact with the paperboard body ply and results in increased container strength and lower manufacturing costs. The foamed adhesive is preferably a foamed aqueous adhesive. The foamed adhesive may be a substantially pure resin adhesive or a mixture of a resin and at least one filler. The two plies may comprise a paperboard body ply and a liner ply adhered together using a foamed adhesive placed therebetween.
