Abstract: Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. An insert is disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

Abstract: Assembly, and method of fabricating an assembly including an extruded polymeric tube and a prefabricated tubular polymer body (fitment), the method including the steps of: extruding an outer tubular surface of a thermoplastic propylene-based elastomer (PBE) material; treating the outer surface along a selected axial length at one end of the tube with a solvent; inserting the treated one end into a hollow tubular passage of a prefabricated tubular body having an inner passage wall of a polypropylene-based material; and allowing the mated juncture to dry such that the treated outer surface solvent bonds to the inner wall. The tubing is preferably a coextruded tube having an innermost layer of a thermoplastic ethylene-based olefinic material. The mating tubing and fitment overcome the prior art problems of stress cracking, fluid contamination and/or processing difficulties.

Abstract: A plastic preform, container or article includes a multilayer wall having at least one layer of a matrix resin, at least one layer of a barrier resin, an adhesion-promoting material blended with the barrier resin and/or matrix resin, and an active oxygen barrier composition blended with the barrier resin and/or matrix resin. The adhesion-promoting material promotes bonding between the barrier and matrix resin layers and includes an amine polymer, preferably an imine polymer having a number of available primary, secondary or tertiary amine groups. The matrix resin preferably is an ester-containing resin, such as PET. The barrier resin preferably is EVOH. The active oxygen barrier composition includes a metal with an additive compound, and may also include a host polymer.

Abstract: A dispensing valve includes a resiliently flexible mounting portion, a resiliently flexible opening portion disposed radially inwardly of the mounting portion, and a resiliently flexible isolating portion disposed radially between and coupled to the mounting and opening portions. The isolating portion extends both radially outwardly and axially to form a first radial space between the opening and isolating portions, and is spaced radially inwardly of the mounting portion to form a second radial space between the mounting and isolating portions. The opening portion may include one or more slits.

Abstract: A child-resistant dispensing closure for a container may include one or the other or both of a dispensing cover non-removably securable to a container, or an outer cover non-removably securable and rotatable with respect to the inner cover and cooperable with the dispensing cover to render the closure child-resistant. According to another embodiment, an outer cover may include a flange to aid users in pushing and turning the outer cover with their fingers.
