A container (10) of variable volume comprises an inner flexible member (1) substantially enclosed in a number of interlocking outer sleeves (3, 14). The volume of the container (10) can be varied by moving at least one outer sleeve (3, 14) relative to another outer sleeve (3, 14). Means for moving the outer sleeves (14, 3) to vary the volume of the container (10) include rotating screw-threaded outer sleeves (3, 14), moving an outer sleeve relative to another by means of a ratchet, or by using multi-level bayonet type connection.
