Abstract: In the making of hollow plastic articles wherein a label is positioned in each of a plurality of spaced partible molds in a predetermined array, a preform is positioned in each set of partible molds and the molds are closed and the preform is blown outwardly to the confines of the mold to apply the label to the resultant hollow plastic article, the apparatus for removing the labels from a conveyor and applying them to the open partible molds which comprises a vacuum head supported for movement between a position for picking up a label and a position for delivering a label to a partible mold. The head comprises an elongated body and a plurality of longitudinally spaced vacuum cups along the body. The body has a transverse cross sectional surface that generally conforms to the cross section of the internal surface of the mold to which the label is to be applied.

Abstract: In an in-molding process of forming plastic containers wherein a label is located inside the blow mold and then a parison is blown outwardly in the mold so that the heat from the parison and the pressure generated by the blow medium activates adhesive on the label to bind the label on the blown container side wall, the method of eliminating undesirable label panel deformation which comprises controlling the moisture of the label such that the shrinkage of the label matches the shrinkage of the plastic side wall against which the label is placed.

Abstract: A container and closure assembly in which the container has a finish portion and the closure is secured to the finish. A circular flexible rubbery sealing liner is located at the top of the container finish and below the cap, and a circular barrier liner that is printable if desired, is provided between the closure top and the flexible liner to reduce the passage of permanents such as O.sub.2 and CO.sub.2 therethrough.

Abstract: A vacuum drum for carrying a label held to its surface by vacuum past an adhesive applying roll to a position where the label will touch a container and the container will be rolled along the drum surface to thereby apply the label about the container. The drum is provided with a circumferential series of vacuum ports that extend through its outer surface. The vacuum to the ports is fed through passages in a bottom support plate for the drum and the passages all communicate with a stationary vacuum chamber in a collector ring which is held against the inner surface of the drum supporting plate. The collector ring vacuum chamber extends about the axis of the ring for about 180.degree. and at one end thereof serves to close off the passages to the drum in radial succession as the label is transferred to the container. Each passage, after being shut off from the vacuum, is vented.

Abstract: In the process of making relief printing plates a liquid photopolymerizably layer having substantially identical negatives on each of its two sides and being in registration and also having a transparent substrate is exposed to an external light source so that both sides are exposed to the same image and after removal of the negatives the unexposed areas of the plate are removed.

Abstract: A multilayer polyethylene structure is disclosed, which is a laminate of at least two layers of high density polyethylene. In one embodiment, a first layer is high density polyethylene of a density of at least 0.959 grams per cubic centimeter and a melt index of about ten grams per ten minutes or less and is about 80 weight percent of the structure. A second layer of the laminate is high density polyethylene of a density to or less than 0.959 grams per cubic centimeter and a melt index of about ten grams per ten minutes or less and is about 20 weight percent of the structure.

Abstract: A preform for making oriented plastic containers wherein the preform is first formed and thereafter reheated to an orientation temperature range and blown to final container shape comprising an open ended finish part made of a first plastic material, and an elongated main hollow body of orientable strain-hardenable thermoplastic material molded and bonded in situ on the open ended finish. The hollow body includes a main container body forming portion and a bottom container forming portion closing the open end of the main body forming portion. The main body has a portion projecting axially within the open end of the finish terminating in a spaced relationship to the open free end of the finish and interlocked with the finish part.

Abstract: A degradable polymer composition having(a) an ethylene-carbon monoxide copolymer only in an amount sufficient to provide a total of substantially about 0.005 to 0.05 percent by weight of CO in the composition; and(b) a low density polyethylene.

Abstract: A high barrier heatset intimate fusion blend article is disclosed where the article includes a blend of a high barrier copolyester, formed from terephthalic acid, ethylene glycol and 1,3 bis(2-hydroxyethoxy) benzene, and poly(ethylene terephthalate) (PET). The PET/copolyester blend articles are formed using a blowmolding and heatsetting process to rapidly achieve a high percentage of crystallinity of the PET in the article. The articles have excellent gas barrier and mechanical strength properties, high thermal stability and remain optically clear after heatsetting.

Abstract: An improved single piece plastic carrier for a plurality of filled and capped bottles in which the neck of each bottle to be carried by the carrier is received in an aperture in the top panel of the carrier and is supported by a pair of spaced apart tabs which extend radially inwardly from the aperture. Each such tab has a substantially greater arcuate extent than the tabs utilized in prior art carriers, and each such tab, therefore, is substantially less yieldable than such prior art tabs. The substantially reduced tab yieldability is advantageous in preventing accidental disengagement of the bottle in the aperture from the carrier. Additionally, the carrier is provided with at least a pair of spaced apart centering lugs near each bottle carrying aperture of the carrier, in the juncture between the top panel of the carrier and the side wall thereof.

Abstract: A hollow transparent delamination resistant heatset multilayer article is disclosed where the article includes at least one barrier layer containing a copolyester formed from terephthalic acid, ethylene glycol and 1,3 bis(2-hydroxyethoxy) benzene directly adhered to at least one layer containing poly(ethylene) terephthalate (PET). The multilayer articles are blowmolded using a heatsetting process. The heatset multilayer articles retain high gas barrier properties, uniform thickness in layers, and desirable mechanical strength properties even after the heatsetting process. Also, the multilayer heatset articles have excellent interlayer adhesion without the need for an adhesive layer, high thermal stability, and remain optically clear after the heatsetting process.

Abstract: A group of degradable polymer compositions including admixtures of ethylene-carbon monoxide copolymer with defined proportions of high density polyethylene, linear low density polyethylene or polypropylene is disclosed. The compositions are useful for forming article carriers, containers, closures, foodtrays and the like, which show excellent mechanical and structural properties and controlled environmental degradability.
