Abstract: A mould 10, 30, 40 particularly for use in food preparation comprising a base 11, and a collar 12 having a continuous wall 14 that upstands from the base with a lower edge 16 of the collar abutting the base 11. The mould may be for single use with the base and the collar being formed from fibreboard and in a particular form the collar wall incorporates a releasable connection to enable opening of the collar. In one form, the collar includes tabs 25 that extend from the lower edge 16 and retaining means (18, 19, 31) which are operative to retain the tabs in relation to the base so as to retain the lower edge 16 of the collar in proximity with the base. The mould further includes in one form an insert 19 which is locatable within the mould cavity 17 and in another form a support arrangement (29, 42, 43) is provided to support the collar wall.
