The neck is formed with an internal shoulder c to receive the picking- washer h, which forms a seat for the disc valve i. The valve is held. on its seat by the ball j, except when the vessel is inverted. The neck is screwthreaded at the mouth to receive the screw plug d, which is formed with a passage f normally closed by a cork &c., and is cemented in position in the neck. The bottom of the plug d is formed with an elongated recess, to prevent the ball j from closing the passage f when the vessel is inverted, and the disc i is bevelled at the edge, so that it tilts forward towards the mouth and permits the passage of the liquid when emptying the vessel.
