Closure element for a fluid container

A closure element 10 for a fluid container (fig 1, 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, which may be in the form of a spherical ball 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. In the unlocked position, the sealing element 30 is located in the fluid pathway 20 to permit fluid to pass along the fluid pathway 20 out 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 ...

Fluid container having two compartments

A fluid container (100) comprises a first compartment (101) and a second compartment (102), each having a first portion (103) in the form of a spiral. The first portion (103) has an open end (104). The first and second compartments (101, 102) are in contacting juxtaposition with each other at at least one contact point. The first portions (103) of the first and second compartments (101, 102) intertwine, thereby linking the two compartments (101, 102). Each first portion may be shaped in the form of a serpentine and a second portion may be provided on both compartments, located away from the openings and may provide a flat side (115). The serpentines may impart a rotational flow of fluid. A closure element and a method of manufacturing a closure element are also provided.
