Abstract:
A self-heating metal can (10) has an indented base (16) defining an external cavity (20) which is utilised to contain beating means. The heating means comprises quicklime (26) filled within a first chamber (28) and water within a second chamber (32) of the cavity (20). A breakable membrane (24) separates the two chambers (28, 32) and the second chamber (32) is closed by closure (30).
