Anti-odour valve consisting of at least three elements, two of which constitute a capsule which fits in the opening of a receptacle, and the third of which is spherical and has a weight such that it floats on the liquid which is to be introduced into the container, thus acting as a cushion inside the capsule. This valve is useful for preventing unpleasant smells from biological liquids (urine) from being smelt, at the same time allowing entry of the liquids into said container. <IMAGE>
