Tiltable metering dispenser

A dispensing device for dispensing liquid in measured amounts, said device comprising:

• a non-pressurized, rigid, substantially fluid tight container for holding liquid, said container having top and bottom portions and an air chamber in said top portion above the liquid level in the container;
• a hollow shell in the bottom portion of said container, said shell having an opening therein for entry of liquid from the container;
• a hollow stem providing a flow passage extending from said shell through the top portion of the container and terminating in a dispensing spout located outside of the container for dispensing of the liquid;
• and
• a vent tube extending within the container at a location outside of said stem, said vent tube having an open lower end defining the level to which liquid can flow into the shell and an open top end located outside of the container to receive outside air.

Apparatus for dispensing liquid in measured amounts, said apparatus comprising:

• an internally pressurized container for holding the liquid, said container being substantially fluid and pressure tight and having top and bottom portions with said top portion presenting a chamber in the container above the liquid when the container is in an upright position;
• a shell and tube structure comprising a hollow shell in said container adjacent said bottom portion thereof and a tube extending from said shell hollow and terminating in a spout end located outside of the container for dispensing of liquid from the container, said shell having an opening for entry of liquid from the container into the shell;
• an orifice in said tube at a location intermediate said hollow shell and spout end;
• and valve means on said spout end for opening and closing said tube,
• whereby said container can be inverted and the liquid in said shell and tube can be dispensed under pressure upon opening said valve means, said orifice acting to equalize the pressure within the container when same is returned to an upright position and additional liquid in the container flows into said shell through the opening therein after closing said valve means.
