A nozzle 100 comprises a nozzle body 10 and an end cap 22 which are axially aligned with one another, the end cap comprising a fluid opening and the nozzle body comprising a closing member which can move axially into contact and away from each other, wherein the end cap and nozzle body are relatively rotatable to vary the axial distance between the fluid opening and closing member, so as to open and close the nozzle. The end cap and nozzle are preferably threaded, and permanently connected to each other. Protrusions may limit the extent of twist. The nozzle may a drink pouch / water bottle cap. The nozzle body may have a base portion and a neck portion with a filling hole through which a fluid / drink can be poured (see figures 5, 6) into the bottle. The neck is subsequently pushed into locking engagement with the base portion, covering / blocking the hole to prevent refilling. |
