Claims7
A composite package comprising an outer package forming a first package made of flexible material and forming a first chamber containing first contents,
- a first closure means sealing the first contents in the first package,
- an inner package forming a second package contained within said first chamber and containing second contents,
- a second closure means sealing said second contents of said second package,
- the closure means of the second package being weaker than the closure means of the first package,
- a third package contained within said first chamber to form an inner package containing third contents,
- dispensing means extending from the third package through the first package,
- the contents of the first and second packages forming a temperature-changing reaction when mixed together,
- whereby the outer package may be squeezed to rupture the closure means of the second package and mix its contents with the contents of the outer package to form a reaction which changes the temperature of the contents of the third package.
