A device (10) for a drinks container (11), the device comprising a straw (16) and means for actuating the straw (16) between a retracted state, in which the straw (16) is housed, in use, substantially within the container (11), and an extended state, in which at least a portion of the straw (16) protrudes, in use, form the container (11). The actuating means may comprise a first casing (12) provided around a portion of the straw (16), the straw (16) and the casing (12) being rotatable with respect to one another about a longitudinal axis, the actuating means further comprising means for imparting generally linear movement to the straw (16) upon relative rotational movement of the casing and the straw portion.

The invention claimed is: 1. A device for a drinks container, the device comprising a straw and means for actuating the straw between a retracted state, in which the straw is housed, in use, substantially within the container, and an extended state, in which at least a portion of the straw projects, in use, from the container: wherein the actuating means comprises a first casing provided around a portion of the straw, the straw and the casing being rotatable with respect to one another about a longitudinal axis, the actuating means further comprising means for imparting generally linear movement to the straw upon relative rotational movement of the casing and straw portion; wherein one of the casing and the straw portion is associated with one or more cam surfaces, the other of the casing and the straw portion being associated with one or more cam followers; wherein the actuating means includes a second casing provided around said portion of the straw and between said straw portion and said first casing, the first and second casings being rotatable with respect to one another about a longitudinal axis, the second casing being shaped to define a slot in which the or each cam follower rides. 2. A device as claimed in claim 1, wherein the second casing includes a handle portion which projects beyond the first casing in the general direction in which the straw is movable towards the extended state. 3. A device as claimed in claim 2, wherein said handle portion comprises a cap for blocking the straw when in the retracted state. 4. A device as claimed in claim 2, wherein the lid is adapated for press-fit engagement with the end of the container that includes the container mouth. 5. A device as claimed in claim 1, wherein the straw carries one or more cam followers in the form of one or more lugs and the first casing comprises one or more cam surfaces in the form of a generally helical track. 6. A device as claimed in claim 1, the device being carried by a lid for the container, the arrangement being such that, when the lid if fitted to the container, the device is seated in the mouth of the container. 7. A container comprising a device as claimed in claim 1.
