Abstract
A hinge for use in inorganically filled composite materials is provided. The hinge has an inorganically filled structural matrix comprising a water-dispersable organic polymer binder, an aggregate material, and a fibrous material. The hinge allows inorganically filled materials to be bent along a line without breakage of the material. The hinge is preferably formed by scoring a formed sheet of inorganically filled material. The hinge is particularly useful in containers that require bending of various container parts, such as in food containers and boxes made from inorganically filled materials.
Claims104
An article of manufacture comprising a first member hingedly attached to a second member by a hinge, at least a substantial portion of said hinge comprising an inorganically filled matrix including a substantially homogeneous mixture of organic binder and inorganic aggregate, said organic binder being selected from the group consisting of polysaccharides, proteins, and mixture or derivatives thereof, said inorganic aggregate having a concentration in a range from about 40% to about 95% by weight of total solids in the matrix, the inorganically filled matrix further including a fibrous material substantially homogeneously dispersed throughout said matrix.
A container comprising a first member hingedly attached to a second member by a hinge, at least a substantial portion of said hinge comprising an inorganically filled matrix including a substantially homogeneous mixture of organic binder and inorganic aggregate, said organic binder being selected from the group consisting of polysaccharides, proteins, and mixtures or derivatives thereof, said inorganic aggregate having a concentration in a range from about 40% to about 95% by weight of total solids in said matrix, said inorganically filled matrix further including a fibrous material substantially homogeneously dispersed throughout said matrix.
An article of manufacture comprising a first member hingedly attached to a second member by a hinge, at least a substantial portion of said hinge comprising an inorganically filled matrix including a substantially homogeneous mixture of organic binder and inorganic aggregate, said inorganically filled matrix being formed by removing a substantial quantity of water by evaporation from an inorganically filled mixture comprising an organic binder selected from the group consisting of polysaccharides, proteins, and mixtures or derivatives thereof, water, an inorganic aggregate material having a concentration in a range from about 40% to about 95% by weight of total solids in said mixture, and fibers substantially homogeneously dispersed throughout said mixture.
