A wash bottle adapted for use in irrigating body tissue surfaces. The bottle comprises a container constituted of flexible resilient material having a mouth. A closure for the mouth is detachable to permit filling of the container with a wash liquid. A nozzle on the closure permits delivery of wash liquid from the container. Conduit means inside the closure and in communication with the nozzle provide for delivery of wash liquid to the nozzle. Valve means comprise a valve seat at an inlet of the conduit means and a stem attached at one end to a portion of a wall of the container and having a free end engageable with the valve seat to prevent entry of liquid into the conduit means from the interior of the container when the container is in an unstressed condition. Said portion of the wall is movable outwardly on squeezing the container to move the stem away from the seat, thereby opening the conduit means to the interior of the container and resulting in the delivery of wash liquid out through the conduit means and nozzle when the bottle is in an inverted position.
