28,487. Atkinson, E. Dec. 2. Stoppers; refilling, preventing. - The neck b of the vessel is formed with a seat c for the hemispherical valve e, and the mouth is adapted to receive the screw plug h, which is irremovably fixed in the neck. The plug h has an outlet i normally closed by a cork j, and may be formed in two parts, the lower part k having a hemispherical boss l corresponding to the recess f in the valve e The plug is also formed with lateral and radial passages m, n, which communicate with the outlet i. The valve rests on its seat when the vessel is upright; and is held on its seat by the boss l when the vessel is horizontal or even slightly inverted, so preventing the introduction of liquid. When the vessel is further inverted, the valve drops from its seat on to the boss l, and allows the contents to flow out through the passages m, n, i.
