CLOSURE ELEMENT A FLUID CONTAINER

摘要

A closure element (10) for a fluid container (100) comprises a fluid pathway (20) having a first open end (21) and a second open end (22). The first open end (21) is adapted to be in fluid communication with the fluid container (100). A sealing element (30) is located in the fluid pathway (20) at its second end (22) and is moveable within the fluid pathway (20). A locking element (40) having an exit aperture (41) is adapted to fit over the second open (end 22) of the fluid pathway (20). The locking element (40) is moveable with respect to the fluid pathway (20) between a locked position and an unlocked position, hi the unlocked position, the sealing element (30) is located in the fluid pathway (20) to permit fluid to pass along the fluid pathway 20 put of the second open end (22) and exit aperture (41). Movement of the locking element 30 towards the first end of the fluid pathway (21) moves it from the unlocked position to the locked position, in which the sealing element 30 is at a location in the fluid pathway 20 which prevents fluid passing along the fluid (pathway 20) out of the second end (22).
