Dosing apparatus used to pour a dose by tilting a container

A dosing apparatus, comprising:

• (a) a container comprising a main chamber;
• (b) a buffer chamber in communication with the main chamber;
• and
• (c) a dosing chamber in communication with the buffer chamber via a constricted channel which forms an anti-siphon in the lower part of the buffer chamber and promotes the formation of a bubble or of a puffing phenomenon;
• whereby the downward tilt of the container at least partially fills the buffer chamber, and the setting upright of the container causes a substance that has entered the buffer chamber to flow into the dosing chamber.

A method of measuring doses of a substance from a dosing apparatus, the method comprising:

• (a) tilting the dosing apparatus from an original position to a tilted position so that the substance contained in a container attached to the dosing apparatus enters a buffer chamber in the dosing apparatus;
• (b) returning the dosing apparatus to the original position so that a predetermined amount the substance flows from the buffer chamber to a dosing chamber in the dosing apparatus and the remaining amount of the substance returns to the container;
• and
• (c) tilting the dosing apparatus again to expel the predetermined amount of the substance from the dosing chamber.

An apparatus for measuring predetermined amounts of a substance, the apparatus comprising:

• (a) a container for storing the substance;
• (b) a buffer chamber of a predetermined volume separated from the container by a wall with an opening;
• and
• (c) a dosing chamber including an opening separated from the buffer chamber by a wall with a constricted channel.
