Abstract: The dispensing lid 10 for the gravity feed dispensing of a liquid includes a main body 12 defining a cavity 14 and adapted, by a screw thread 16, for releasably attaching any lid 10 to the container in a sealing manner. Spout 18 extends from the main body 12 and is fitted with an adjustable discharge valve 20 for varying the rate at which liquid flows through the spout 18. Air bleed passage 22 is formed in the lid for enabling fluid communication between the cavity 14 and the external atmosphere. The lid 10 also includes a manually operable air bleed valve 24 for selectively opening and closing the air bleed passage 22. Air bleed valve 24 is biased to normally close the passage 22. When the lid 10 is attached to a container by the screw thread 16 liquid can be dispensed or poured through the spout 18 by action of gravity at a rate dependent on the position or state of both valves 20 and 24.

A distributing aperture in the side wall on the upper portion of a cylindrical hydrant housing is closable to a desired degree by a hollow cylindrical cap member that is threadable into the interior of the hydrant housing. The threaded cap is captured within the interior of the housing by means of a limit pin disposed above the distributing aperture, such pin contacting the aperture-blocking portion of the cap when such cap is threaded outwardly to an upper limit, in which position the aperture is fully exposed. A longitudinal bore extends completely through the cap for shunting a portion of the irrigation fluid in an upwardly directed path while the hydrant is below ground level, such bore terminating in a nozzle for saturating the surrounding soil with a fine jet-like spray to facilitate the upward movement of the hydrant out of the ground.
