Appropriate additives can also be added to the mixture which impart desired characteristics and properties to both the mixture and the hardened containers. The mixtures can be utilized to form containers by various methods. One method involves forming the containers without substantial mixing of the mixture, compacting the mixture and hydrating the mixture. Other methods involve molding the mixture, extruding the mixture and forming sheets from the mixture to be converted into containers. The components may also be dried, coated, lined, laminated and/or receive printing.Type: GrantFiled: June 7, 1995Date of Patent: February 3, 1998Assignee: E.

Patent number: 5709913Abstract: Compositions, methods, and apparatus for manufacturing sheets having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form a sheet which has the desired performance criteria. The inorganically filled mixtures are formed into sheets by first extruding the mixtures and then passing the extruded materials between a set of rollers. The rolled sheets are dried in an accelerated manner to form a substantially hardened sheet, such as by heated rollers and/or a drying chamber. The inorganically filled sheets may have properties substantially similar to sheets presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. Such sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheet.Type: GrantFiled: June 7, 1995Date of Patent: January 20, 1998Assignee: E.
