IMPROVEMENTS RELATING TO A HEATER UNIT FOR A SELF-HEATING CONTAINER

摘要

The invention provides a single-piece carrier member (38) for assembly of a heater unit (36) for a self-heating container, e.g. a food pack. The carrier member (38) includes foldable fingers (64) for securing an annular solid fuel tablet (66) to the carrier member (38), and a sleeve in which are mounted a friction ignition head (48) and a manually operated slidable striker (46). The carrier member (38) has tabs (68) to enable the unit to be installed securely in a self-heating container. The carrier member (38) can be formed from a blank which is folded on itself to form the sleeve, the fingers (64) then folded inwardly, and the tabs (68) then folded downwardly. The carrier member (38) is made of tinplate.
