Abstract: A thermoformed packaging tray is provided which includes a container having a bottom surface, an integrally formed peripheral side wall extending upwardly from the bottom surface. The sidewall defines an open top. A rigid lip is provided on a top edge of the peripheral side wall; and a remote end of the lip which diminishes in thickness to become flexible.

Abstract: There is a tube container that is resistant to water infiltration into the cavity between the head and the cap. The tube container has a body wall and a head. The body wall defines a chamber therein. The head has a shoulder, which has an orifice therethrough in communication with the chamber. The shoulder has a ridge extending therefrom adjacent its periphery. The ridge substantially blocks the infiltration of water when the cap is secured to the head.

Abstract: A tubular dispensing container has a head whose shoulder is joined to a tubular body. The head and shoulder can be thin because they are provided with a plurality of ribs that extend axially from the neck to the lower end of the shoulder and rigidify the head. A head for a tubular dispensing container is provided having the above-mentioned ribs. Apparatus for forming the head has male or female tooling with axially grooves formed therein to form the ribs on the inside or outside surface of the head. Methods involve flowing moldable material along the grooves to provide the lower end of the shoulder of the head with enough moldable material at elevated temperature and pressure to form a good bond of the shoulder with the tubular body.

Abstract: There is a plastic dispensing tube having shaped corners. The dispensing tube has a tubular plastic sleeve and a plastic head affixed to one end of the sleeve. The sleeve has an interior surface. The head defines a neck having a passageway therethrough and a shoulder defining one or more corners therein. The head further defines one or more ribs extending from the one or more corners into the sleeve. The one or more ribs is affixed to the interior surface of the sleeve. There is also a process for making the plastic dispensing tube.

Abstract: Copolymers of ethylene and alpha olefins that have been formed by the polymerization reaction in the presence of a single site catalyst, such as a metallocene, are used to form collapsible dispensing containers and/or components thereof. Blends of the copolymers with propylene polymers are disclosed and used to form a body wall layer or a collapsible dispensing container head having good bond strength with a body wall layer formed of an ethylene polymer. Methods for improving the adhesion between collapsible dispensing container components, such as between body wall layer formed of an ethylene polymer and another body wall layer formed of a propylene polymer, or between a body wall layer formed of an ethylene polymer and a collapsible dispensing container head formed of a propylene polymer, are also disclosed.

Abstract: A container configuration having two and three-dimensional characteristics on a single multiple dimensional surface that define a portion of the container. The combination of certain three-dimensional surface areas with two-dimensional graphic indicia overlay wherein indicia impart enhanced dimensional characteristics to actual multi-dimensional surfaces not having the physical characteristics imparted by the surface themselves.

Abstract: Disclosed is a container for receiving contents from another container. The container has a receptacle and a head. The receptacle has a chamber therein. The head has a neck. The neck has a receiving orifice therein and a bore therethrough. The receiving orifice communicates with the chamber through the bore. The neck further has an inner surface contiguous to the receiving orifice and/or the bore. The inner surface has a plurality of splines extending therefrom and generally directional to the longitudinal extension of the neck. Further disclosed is a tube container. Still further disclosed is a method for introducing the contents of one container into another container.

Abstract: An improved coextruded asymmetric multilayer plastic structure and method of forming the same are provided. The layers of the structure consist of a barrier layer comprised of an ethylene vinyl alcohol copolymer, an adhesive layer on each surface of the barrier layer, inner and outer surface layers, and a bulk layer positioned between the outer surface layer and its adjacent adhesive layers. The bulk layer is comprised of a thermoplastic polymer and calcium carbonate in an amount sufficient that the multilayer structure has an acceptable level of curling. The structure can be used to form a tubular body that has a cylindrical shape. A collapsible dispensing container having a body wall formed of the aforementioned structure and having improved product dispense properties is also provided.
