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.
Claims112
An article of manufacture comprising a hinged inorganically filled matrix including a substantially homogenous mixture of aggregate and organic binder, said matrix being formed from an inorganically filled mixture comprising water, a water-dispersible organic polymer binder selected from the group consisting of polysaccharides, proteins, and mixtures or derivatives thereof, an inorganic aggregate material having a concentration in a range from about 40% to about 98% by volume of total solids in said inorganically filled mixture, and a fibrous material substantially homogeneously dispersed throughout said inorganically filled matrix.
The article of manufacture of claim 84, wherein said pulp-containing material is a paper strip.
An article of manufacture comprising a hinged inorganically filled matrix including a substantially homogeneous mixture of aggregate and organic binder, said matrix being formed from an inorganically filled mixture comprising:
- a water,
- (b) a water-dispersible organic polymer binder selected from the group consisting of polysaccharides, proteins, and mixtures or derivatives thereof and having a concentration in a range from about 1% to about 50% by volume of total solids in the inorganically filled mixture;
- (c) an inorganic aggregate material having a concentration in a range from about 40% to about 98% by volume of total solids in the inorganically filled mixture;
- and
- (d) a fibrous material having a concentration in a range from about 0.5% to about 50% by volume of total solids in the inorganically filled mixture, wherein said hinged matrix has a thickness of about 0.01 mm to about 1 mm, and wherein said fibrous material is substantially homogeneously dispersed throughout said inorganically filled matrix.
An article of manufacture comprising a hinged inorganically filled matrix including a substantially homogenous mixture of an inorganic aggregate and an organic binder, said matrix further including fibers substantially homogeneously dispersed throughout said inorganically filled matrix, 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 98% by volume of total solids in said inorganically filled matrix.
