Abstract
A fire and heat resistant container having at least the sidewall partially formed from fibrous material with an inner surface and an outer surface that has a plurality of laminae of predetermined composition and thickness arrayed in a specific manner therebetween is provided to protect an object or substance adjacent the inner surface from a fire or heat generating source adjacent the outer surface. The laminae are bonded together by a fire resistant bonding agent of predetermined thickness.
Claims86
A fire and heat resistant container having a top and a bottom interconnected by sidewall means, at least the sidewall means being partially formed from fibrous material and having an inner surface and an opposing outer surface with a plurality of laminae therebetween to protect an object adjacent the inner surface from a fire or heat generating source adjacent the outer surface, the combination comprising:
- (a) a first lamina of predetermined thickness generally defining the inner surface and formed at least partially of aluminum;
- (b) at least one ply adjacent the first lamina and comprising:
- i. a second lamina of fibrous material of predetermined thickness and strength adjacent the first lamina;
- ii. a third lamina of predetermined thickness formed at least partially of aluminum and having generally planar opposing sides;
- iii. a fourth lamina of fibrous material of predetermined thickness and strength adjacent the third lamina;
- iv. a first bonding agent bonding each lamina of fibrous material to each of the opposing sides of the third lamina;
- and
- (c) a second bonding agent of predetermined thickness bonding the at least one ply to the first lamina.
A fire and heat resistant container having a top and a bottom interconnected by sidewall means, at least the sidewall means being partially formed from fibrous material and having an inner surface and an opposing outer surface with a plurality of laminae therebetween to protect an object adjacent the inner surface from a fire or heating generating source adjacent the outer surface, the combination comprising:
- (a) a first generally planar lamina of predetermined thickness generally defining the inner surface formed at least partially of aluminum;
- (b) a plurality of plies adjacent the first lamina including at least an innermost ply and an outermost ply such that the innermost ply is a shorter distance from the inner surface than the outermost ply, each ply comprising:
- i. a second generally planar lamina of fibrous material of predetermined thickness and strength adjacent the first lamina;
- ii. a third generally planar lamina of predetermined thickness and strength formed at least partially of aluminum and having generally planar opposing sides with one of the opposing sides being adjacent the second lamina;
- iii. a fourth generally planar lamina of fibrous material of predetermined thickness and strength adjacent the other of the opposing sides of the third lamina;
- and
- iv. a first bonding agent bonding each lamina of fibrous material to each of the opposing sides of the third lamina;
- (c) at least one lamina of fibrous material of predetermined thickness and strength bonded to the outermost ply by a second bonding agent;
- and
- (d) a third bonding agent of predetermined thickness bonding each ply to each adjacent ply.
In a fire and heat resistant container for storing combustion promoting substances, the container having a top and a bottom interconnected by improved sidewall means having an inner surface and an opposing outer surface, the improvement comprising:
- the inner surface having a polymer material of predetermined thickness coating a first lamina of predetermined thickness formed at least partially of aluminum, the first lamina being bonded to at least one ply, each ply comprising in sequence a second lamina of fibrous material of predetermined thickness and strength bonded to a third lamina of predetermined thickness and strength formed at least partially of aluminum and bonded to a fourth lamina of fibrous material of predetermined thickness and strength, each adjacent ply further being bonded together by a bonding agent of predetermined thickness.
