Patent number: 6455144Abstract: A laminate for reinforcing a structural member having a plurality of side walls comprises a carrier having at least one inclined support surface. Each support surface has an outer edge disposed toward a respective side wall. A layer of extruded uncured structural foam is on each support surface and terminates inwardly of the outer edge. The foam expands when cured and tumbles down the inclined support surface of the carrier to become bonded to the side wall as well as the carrier. By being spaced from the outer edge of the support surface, the tendency for the foam to wipe against the side wall is minimized as is the tendency for a worker to touch the foam when the worker places the carrier into the structural member.Type: GrantFiled: May 30, 2000Date of Patent: September 24, 2002Assignee: Henkel CorporationInventor: Joseph S. Wycech

Patent number: 6440530Abstract: Lids, for example, lids for machine-lidding of, e.g., beakers, dishes, menu dishes, goblets, small packages, etc., containing a substrate material featuring, with respect to a container on which the lids are used, a smooth outward facing surface bearing printing. On the inward facing side of the lid is a sealing layer deposited by extrusion laminate coating. The sealing layer exhibits on the free surface embossing with a depth of roughness of up to 50 &mgr;m. The embossing is transferred to the sealing layer in the form of a roughness pattern on the cooling roll on depositing the laminate coating of the substrate material and extruded sealing layer. The free side of the substrate material is smooth and exhibits no embossing. Printing on the free surface is therefore of higher quality. The extruded sealing layer on the substrate material exhibits embossing on the free side. If the lids are drawn from a stack of lids, for example, in a filing machine, the embossing allows them to be separated individually.Type: GrantFiled: December 15, 1999Date of Patent: August 27, 2002Assignee: Alcan Technology & Management Ltd.Inventor: Wilfried Jud

Patent number: 6436508Abstract: The present invention relates to absorbent article such as sanitary napkins and panty liners comprising a topsheet, absorbent core, and backsheet which are breathable by the incorporation of a breathable backsheet and have a reduced tendency to exhibit garment wet through. The backsheet comprises at least one air permeable layer such as an apertured formed film or fibrous layer which is applied and preferably coated with a non-soluble, liquid swellabe material, such as polyvinyl alcohol. Upon contact with fluid discharge, the material swells and closes the apertures of the layer, thereby reducing air permeability and preventing the passage of liquid through the layer and thus through the backsheet onto the garment of the wearer of the article.Type: GrantFiled: April 19, 2000Date of Patent: August 20, 2002Assignee: The Procter & Gamble CompanyInventors: Fabio Ciammaichella, Michael Divo, Italo Corzani

Patent number: 6432512Abstract: A foam plank laminate of thermoplastic material comprises at least two expanded foam sheets, both partially perforated, and laminated with the perforated surfaces facing each other and the smooth non perforated surfaces as the outer plank surfaces. The foam plank laminate can be obtained by an industrially acceptable production method as the partial perforation of the forming foam sheets accelerates the removal of a majority of the blowing agent from the foam structure, thus drastically reducing the curing time, and at the same time it has impermeability, good mechanical properties, and an attractive appearance.Type: GrantFiled: February 1, 2000Date of Patent: August 13, 2002Assignee: Sealed Air Corporation (US)Inventor: Maurizio Brandolini

Patent number: 6432525Abstract: In the present invention, for the production of a blow-molded foam, there is used a base resin which is mainly composed of a polypropylene resin and has, at 230° C., a melt tension (MT) of 10 gf or over and a melt flow rate (MFR) of 0.5 g/10 minutes or over. A foaming agent is added to the base resin, followed by melt kneading by means of an extruder under high temperature and high pressure conditions to provide a foamable melt. This melt is subjected to extrusion from a circular die 5 and expanded to form a cylindrical foamed parison 4. Thereafter, molds 6, 6 are clamped, and the parison 4 in a softened condition is placed in the molds 6, 6, and a pressurized gas is blown into the parison 4 from a gas blowing port 7 for blow molding in the form of a hollow shape conforming to the mold profile to produce a blow-molded foam.Type: GrantFiled: May 17, 2000Date of Patent: August 13, 2002Assignee: JSP CorporationInventors: Hiroyuki Gokuraku, Naochika Kogure, Takashi Kitahama
