Claim 12

A first aid kit as claimed in claim 3 and wherein the water contains a preservative.

Claim 13

A first aid kit as claimed in claim 3 and wherein the reservoir and first compartment are adapted to hold water and reactor respectively in a weight ratio of between 4 and 5:1.

Claim 14

A first aid kit as claimed in claim 3 and wherein the second compartment is adapted to hold about five 8 cm broad roller bandages in 3 cm diameter rolls.

Claim 15

A first aid kit for treating burns to human or animal tissue and comprising a reservoir and first and second compartments in line, the reservoir forming the base of the kit and having in the top thereof a spring loaded valve normally sealing the container, the first compartment having perforated end walls and associated with the reservoir in such a way as to be both detachable therefrom to permit charging the reservoir with water and operable with respect thereto to open the valve, the first compartment being accessible to permit charging with a non-toxic endothermic reactor and being adapted both to retain the reactor and to allow water therethrough into the second compartment, and the second compartment being adapted to contain absorbent dressing and being readily openable to permit charging with and removal of the dressing and adapted to contain water when inverted, the first compartment being attached to the reservoir by bayonet means and the second compartment being attached to the first by a coarse, multi-start screw thread.

Claim 16

A first aid kit for treating burns to human or animal tissue and comprising a reservoir and first and second compartments in line, the reservoir forming the base of the kit and having in the top thereof a spring loaded valve normally sealing the container, the first compartment having perforated end walls and associated with the reservoir in such a way as to be both detachable therefrom to permit charging the reservoir with water and operable with respect thereto to open the valve, the first compartment being accessible to permit charging with a non-toxic endothermic reactor and being adapted both to retain the reactor and to allow water therethrough into the second compartment, and the second compartment being adapted to contain absorbent dressing and being readily openable to permit charging with and removal of the dressing and adapted to contain water when inverted, the first compartment being attached to the reservoir by bayonet means and the second compartment being attached to the first by a coarse, multi-start screw thread.

Claim 17

A first aid kit for treating burns to human or animal tissue and comprising a reservoir and first and second compartments in line, the reservoir forming the base of the kit and having in the top thereof a spring loaded valve normally sealing the container, the first compartment having perforated end walls and associated with the reservoir in such a way as to be both detachable therefrom to permit charging the reservoir with water and operable with respect thereto to open the valve, the first compartment being accessible to permit charging with a non-toxic endothermic reactor and being adapted both to retain the reactor and to allow water therethrough into the second compartment, and the second compartment being adapted to contain absorbent dressing and being readily openable to permit charging with and removal of the dressing and wherein the reactor comprises anhydrous crystals of urea and the reservoir and first compartment are adapted to hold water and reactor respectively in a weight ratio of between 4 and 5:1.
