Bottled water cooler having vent on demand delivery system

A water delivery system for dispensing water at first and second temperatures from a bottle comprising:

• means for drawing water from said bottle;
• means coupled to said drawing means for sealing the interior of said bottle from the atmosphere;
• means coupled to said sealing means for selectively venting the interior of said bottle to atmosphere;
• first means coupled to said drawing means for providing and dispensing water at a first temperature;
• second means coupled to said drawing means for providing and dispensing water at a second temperature;
• first actuation means coupled to said first means and to said venting means for causing said venting means to vent the interior of said bottle to atmosphere and to cause said first means to dispense water at said first temperature;
• second actuation means coupled to said second means and to said venting means for causing said venting means to vent the interior of said bottle to atmosphere and to cause said second means to dispense water at said second temperature.

A water delivery system for dispensing water from a bottle, comprising:

• means for drawing water from said bottle;
• means coupled to said drawing means for sealing the interior of said bottle from the atmosphere;
• means coupled to said sealing means for selectively venting the interior of said bottle to the atmosphere;
• actuation means operatively connected to said drawing means and to said venting means and having sequence establishing means for sequentially causing said venting means to vent the interior of said bottle to atmosphere and to cause said drawing means to dispense water from said bottle;
• and
• level sensing means responsive to the water in said bottle for preventing said drawing means from dispensing water in response to said actuation means when the water in said bottle reaches a predetermined level.

A delivery system for dispensing water from a bottle, comprising:

• water draw tube communicating with the interior of said bottle;
• electrically actuated pumping means for applying a force tending to urge water in said bottle through said drawn tube;
• means coupled to said draw tube for sealing the interior of said bottle form atmosphere;
• means coupled to said draw tube for sealing the interior of said bottle from atmosphere;
• actuation means electrically coupled to said pumping means and also coupled to said venting means for causing said venting means to vent the interior of said bottle to atmosphere and for also electrically actuating said pumping means;
• wherein said actuation means includes sequence establishing means for establishing a relationship between the time at which said venting means is caused to vent the interior of said bottle to atmosphere and the time at which said pumping means is electrically actuated.
