Abstract
A valve for a body fluid storage container comprises a valve body (11) and a manually operable valve member (10) rotatable in a through aperture (14) therein, between an open disposition in which a touch surface (30,31) of the valve member stands away from the fluid flow path (15) through the valve and a closed disposition in which it lies close to it. The valve member has a unitary construction in which a first limb (33) extends from an insert portion (37) of the valve member, at one end of the through aperture, to the touch surface, and a second limb extends from the touch surface to a retaining portion (40) which engages, at the other end of the through aperture, with a leading end (42) of the insert portion to hold the valve member in position in the valve body. This two-part valve provides a cheap disposable item for use with disposable containers.
