Publication number: 20140318329Abstract: A process for producing molded products having portions formed with two separate materials is provided, The process involves forming a first component over a structural core in a first step, and forming a second component that is secured to the first component and the core in a second step. The second component can be formed directly over the first component or can be secured thereto after formation. The first and second components can additionally be formed with indicia thereon, or with recesses within which inserts containing the desired indicia can be positioned. Additionally, the first component can be formed with a ridge disposed on a projection formed on the first component that effectively seals off a portion of the first component when the second component is formed around the core and the first component to ensure the portion of the first component surrounded by the ridge remains visible after formation of the second component.Type: ApplicationFiled: May 9, 2014Publication date: October 30, 2014Applicant: Gauthier Biomedical, Inc.Inventors: Michael T.

Publication number: 20140319725Abstract: Methods and systems for co-extruding multiple polymeric material flow streams into a mold having a plurality of cavities to produce a plurality of multi-layer polymeric articles each having a consistent coverage of an interior core layer are disclosed herein. In an example method, a flow rate of a first skin material into a cavity is individually controlled for each cavity before initiation of co-injection of a second core material into the cavity, which may address inconsistent interior core layer coverage for articles from different cavities.Type: ApplicationFiled: July 9, 2014Publication date: October 30, 2014Inventors: John Duffy, Scott Hickey

Publication number: 20140317839Abstract: Swimming pool safety coping element and method of manufacture thereof The present invention relates to coping elements, in particular to coping elements used around the edge of a swimming pool. A swimming pool safety coping element (10) comprises an outer layer portion (12) and an infill portion (14), the outer layer portion at least partly bounding the infill portion. The coping element is manufactured by forming the outer layer portion from a Low Surface Energy material. A pressure sensitive adhesive (16) is then applied across a first surface of the outer layer portion. In a further step, a flowable polymer composition is poured onto the first surface of the outer layer, and allowed to set, to provide the infill portion.Type: ApplicationFiled: February 24, 2012Publication date: October 30, 2014Inventor: Mark Nicholas Hempleman-Adams

Publication number: 20140302264Abstract: A hollow element assembly has a base and a lid. The base has a wall that at least partly defines a recess, and the lid is locatable on the base so as to further bound the recess. Location of the lid on the base is achieved by bringing an edge of the wall into abutting contact with a corresponding contacting surface on the lid. At least one of the edge of the wall and the contacting surface of the lid has a channel running there along, such that when the lid is located on the base, a welding conduit is provided that follows the edge of the wall. At least one of the base and the lid further has an inlet aperture arranged to deliver molten welding material to the welding conduit from a region external to the hollow element assembly, so as to weld the base and the lid together, to provide a hollow element.Type: ApplicationFiled: June 1, 2012Publication date: October 9, 2014Applicant: Barkley Plastics LimitedInventors: Maurice Cassidy, Justin Anstey
