Patent number: 4693056Abstract: Sealing of elongated packaging laminates of backed antistatic foam around spaced articles being packaged, using edge seals made by first applying heated melting shoes against foam edges of both laminates, then joining the melted foam edges and subjecting the assembly to rollers that press together the joined laminates. Preferably the backing has aluminum layer secured to the foam by pressure-sensitive adhesive. Edge seals can be further subjected to pressure sustained for at least about a second, as while similar pressure is used to apply transverse heat seals to the edge-jointed laminates.Type: GrantFiled: October 4, 1985Date of Patent: September 15, 1987Assignee: The Crowell CorporationInventor: Lewis R. Raszewski

Patent number: 4658567Abstract: A polyurethane foam packing unit formed in desired cross-sectional configuration and having a relatively low density. A block which may also be formed of polyurethane or the like is disposed within the unit, and possesses a higher density than that of the mass. A polyurethane flexible liner encompasses the mass and the block embedded therein. The invention further incorporates the method of producing such a unit.Type: GrantFiled: February 19, 1982Date of Patent: April 21, 1987Inventor: Carl T. Arada

Patent number: 4644733Abstract: Loose fill packing material comprising a plurality of expanded, resilient, thermoplastic dunnage particles, which particles are rendered more effective by coating an outer surface thereof with an additive which additive results in the packing material having improved cushioning properties and reduces the tendency of articles to migrate through the dunnage particles, wherein the particles have an average maximum cross-sectional dimension of at least 0.5 inch.Type: GrantFiled: January 16, 1986Date of Patent: February 24, 1987Assignee: The Dow Chemical CompanyInventor: Blair E. Dolinar

Patent number: 4640080Abstract: A process to form a generally rigid cushion package from loose fill dunnage material. The loose fill dunnage material is particles of cellular thermoplastic or thermosetting material. The process involves surrounding, within a second packaging enclosure, the article to be packaged with an amount of loose fill dunnage material. The second packaging enclosure is placed in a first packaging enclosure. The second packaging enclosure has an original volume greater than internal volume of the first packaging enclosure. An internal vacuum is created in the second packaging enclosure causing the original volume of material therein to decrease below the internal volume of the first packaging enclosure. The first packaging enclosure is sealed and the vacuum within the second packaging enclosure released.Type: GrantFiled: November 29, 1985Date of Patent: February 3, 1987Assignee: The Dow Chemical CompanyInventor: Donald R. Wright

Patent number: 4598530Abstract: A light weight, shipping package for small glass vials and the like and providing an expanded polystyrene package having a plurality of chambers aligned opposite one another and including thin outer walls formed by first producing the package as a large billet and thereafter simultaneously cutting the billet into individual packages and thus achieving an objective of having a thin wall package without the attendant high production costs normally encountered in thin wall package construction.Type: GrantFiled: June 24, 1985Date of Patent: July 8, 1986Inventors: Joey L. Barnes, James K. Barnes

Patent number: 4584822Abstract: A cushion packing material for use in protecting objects from shock and vibrational loads. The cushion packing comprises a dimensionally stable thermoformed shell forming a chamber therein of a predetermined configuration and having a foam material disposed therewithin so as to provide a molded density of less than or equal to 1.5 pounds per cubic foot. Preferably, the foam comprises a low density polyurethane foam. The dimensionally stable shell is thermoformed in a mold and is removed therefrom for filling with the low density foam. The cushion packing provides substantially equivalent or improved cushioning benefits in terms of dissipating dynamic forces at higher static stresses or loadings.Type: GrantFiled: March 7, 1984Date of Patent: April 29, 1986Assignee: Sealed Air CorporationInventors: Alfred W. Fielding, George T. Bertram, Semyon Krislav, Joel Askinazi

Patent number: 4468913Abstract: Method and box for conditioning products which must be stored under determined temperature conditions, generally different from the conditions of the environment. The method consists in placing within an open, thermally insulated enclosure (1), some removable reserve elements (26 to 30), placing the products within the volume delimited by the reserve elements (26 to 30) inside the enclosure (1), removing the reserve elements (26 to 30), replacing them by heat or cold accumulating elements brought to the required predetermined temperature and having shapes and dimensions similar to those of the reserve elements (26 to 30), and closing the enclosure (1). Application to the conditioning of products sensitive to temperature, especially such as vaccines, serums, etc.Type: GrantFiled: December 23, 1981Date of Patent: September 4, 1984Assignee: SofrigamInventors: Claude R. Guillon, Annick Schwarz
