Methods of dispensing liquids from pouring heads

A method of dispensing liquid from a bottle, comprising the steps of

• a) magnetically latching a ferrous valve member to a normally open condition relative to a mating valve seat at a magnetized valve latch pad in a dispensing head secured to a bottle of liquid;
• b) manually inverting the bottle and head and pouring the liquid out of the bottle through the head and past the ferrous valve member;
• c) timing a period of dispensing before automatically demagnetizing the valve latch pad and dropping the ferrous valve member to close said valve seat while the adjoined bottle and head are inverted;
• and
• d) overiding the automatic demagnetizing of the valve latch pad to provide a relatively early termination of dispensing to thereby obtain a fractional pour.

A method of dispensing liquid from a bottle, comprising the steps of

• a) magnetically locking a ferrous valve member to a magnetic valve latch pad to define a normally open condition relative to a valve seat in a dispensing head secured to a bottle of liquid and wherein said ferrous valve member, said latch pad and means for demagnetizing said valve latch pad are mounted inside said bottle;
• b) manually inverting the bottle and head and pouring the liquid out of the bottle through the head and past the ferrous valve member;
• and
• c) demagnetizing the valve latch pad and dropping the ferrous valve member to close said valve seat while the adjoined bottle and head are inverted, thereby terminating dispensing of liquid from the bottle.

A method of dispensing a plurality of predetermined quantities of liquid from a bottle, comprising the steps of

• a) connecting a pouring head to a bottle of liquid;
• b) inverting the connected head and bottle and pouring liquid from the bottle and out of the head;
• c) sensing that pouring of liquid has commenced;
• d) timing a period of dispensing;
• e) electromagnetically releasing a magnetically responsive valve to close the head and terminate liquid dispensing, upon expiration of the time period, given one predetermined quantity of dispensed liquid;
• f) vertically shaking the inverted head and bottle;
• and causing the valve to jump upward in the head;
• g) magnetically latching the valve during the vertical shaking of the head and bottle;
• h) electronically sensing that the bottle and head are inverted and that the valve is magnetically latched;
• and
• i) electronically re-starting the timer to pour a subsequent predetermined quantity of liquid from the bottle.

A method of dispensing liquid from a bottle, comprising the steps of

• a) magnetically latching a ferrous valve member to a normally open condition relative to a mating valve seat at a magnetized valve latch pad in a dispensing head secured to a bottle of liquid;
• b) manually inverting the bottle and head and pouring the liquid out of the bottle through the head and past the ferrous valve member;
• c) timing a period of dispensing before demagnetizing the valve latch pad and dropping the ferrous valve member to close said valve seat while the adjoined bottle and head are inverted;
• and
• d) delaying the step of demagnetizing said latch pad to extend the dispensing period to obtain a relatively large pour.
