Abstract
A fluid container and capsule therefor. The capsule comprises upper and lower parts, at least one of which has a dished formation and both of which have a peripheral rim, the rims being secured together so that the upper and lower parts are at least partially in register with one another to provide at least one vented chamber extending into the dished formation. The capsule includes a vent hole or like structure in at least one of the parts to communicate between the interior of the chamber and the exterior thereof. The lower part has its exterior so formed as to enable it to be held in stable engagement with a surface but so that a fluid may pass freely between those parts of the exterior of the lower part and the surface that are not in intimate engagement.
