Liquid dispenser

Claim 2

Apparatus for controllably dispensing a precise amount of liquid from a sealed container to an open-topped container, comprising: means for supporting said sealed container, means connected to said sealed container for alternately establishing a negative and positive pressure within the container, conduit means extending from the interior of said sealed container to a preselected point in the interior of said opentopped container and having its outside terminal portion extending in a downwardly direction, guide means connected To said support means for guiding and aligning the open-topped container telescopingly over the terminal end of said conduit, and, means connected to said guide means for adjusting the vertical position thereof.

Claim 3

The apparatus as claimed in claim 1 wherein said pressure establishing means extends into the sealed container and above the level of liquid in the container to establish a positive and negative pressure upon the surface of the liquid in the container.

Claim 4

The apparatus claimed in claim 1 wherein said conduit means extends to a point within said sealed container which point is below the liquid level in the sealed container.

Claim 5

The apparatus as claimed in claim 1 wherein the preselected point in the interior of the open-topped container corresponds to the desired level of liquid to be dispensed into said open-topped container.

Claim 6

The apparatus as claimed in claim 1 including indicia means adjacent to said guide means for indicating the volume of liquid to be dispensed into said open-topped container.

Claim 7

Method for controllably dispensing a precise amount of liquid from a sealed container to an open-ended container through a conduit means, comprising the steps of: supporting said sealed container, positioning said open-ended container in an upright position, positioning said conduit means between the interior of said sealed container and the interior of said open-ended container so that the outside terminal portion of said conduit means extends in a downwardly direction within said open-ended container, guiding and aligning said open-topped container telescopically over the terminal end of said conduit means so that the terminal end of said conduit means coincides with a predetermined point in the interior of the open-ended container corresponding to a preselected volume encompassed by the container volume below said point, and alternately applying a positive and negative pressure within the sealed container to deliver an excess of the desired amount of liquid through said conduit and into said open-ended containers and to withdraw the excess.

Claim 8

Method for controllably dispensing a precise amount of liquid from a sealed container to an open-ended container through a conduit means, comprising the steps of: supporting said sealed container, positioning said open-ended container in an upright position, positioning said conduit means between the interior of said sealed container and the interior of said open-ended container so that the outside terminal portion of said conduit means extends in a downwardly direction within said open-ended container, guiding and aligning said open-topped container telescopically over the terminal end of said conduit means so that the terminal end of said conduit means coincides with a predetermined point in the interior of the open-ended container corresponding to a preselected volume encompassed by the container volume below said point, and alternately applying a positive and negative pressure within the sealed container to deliver an excess of the desired amount of liquid through said conduit and into said open-ended containers and to withdraw the excess.

Claim 9

Method for controllably dispensing a precise amount of liquid from a sealed container to an open-ended container through a conduit means, comprising the steps of: supporting said sealed container, positioning said open-ended container in an upright position, positioning said conduit means between the interior of said sealed container and the interior of said open-ended container so that the outside terminal portion of said conduit means extends in a downwardly direction within said open-ended container, adjusting the relative position of said open-ended container and the terminal end of said conduit means telescoped therein so that the terminal end of said conduit means coincides with a predetermined point in the interior of said container, and applying a positive pressure within the sealed container to force a quantity of liquid through said conduit and into said open-ended containers to a depth greater than the position of the terminal portion of said conduit, and then applying a negative pressure within the sealed container to return that quantity of liquid from the open-ended container that is above the terminal portion of the conduit.

Claim 10

Method for controllably dispensing a precise amount of liquid from a sealed container to an open-ended container through a conduit means, comprising the steps of: supporting said sealed container, positioning said open-ended container in an upright position, positioning said conduit means between the interior of said sealed container and the interior of said open-ended container so that the outside terminal portion of said conduit means extends in a downwardly direction within said open-ended container, adjusting the relative position of said open-ended container and the terminal end of said conduit means telescoped therein so that the terminal end of said conduit means coincides with a predetermined point in the interior of said container, and applying a positive pressure within the sealed container to force a quantity of liquid through said conduit and into said open-ended containers to a depth greater than the position of the terminal portion of said conduit, and then applying a negative pressure within the sealed container to return that quantity of liquid from the open-ended container that is above the terminal portion of the conduit.
