Patent number: 7204381Abstract: 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.Type: GrantFiled: April 4, 2002Date of Patent: April 17, 2007Assignee: Pechiney Plastic Packaging, Inc.Inventors: John J.

Patent number: 6846443Abstract: 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.Type: GrantFiled: September 15, 2000Date of Patent: January 25, 2005Assignee: Pechiney Plastic Packaging, IncInventors: Douglas J Jackson, Daniel L King

Patent number: 6383589Abstract: 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.Type: GrantFiled: March 29, 1999Date of Patent: May 7, 2002Assignee: Pechiney Plastic Packaging, Inc.Inventors: David C.
