Inverted Bottle Dispensing Systems and Methods

A dispensing system, comprising:

• a bottle including a proximal end and a distal end separated by a side wall which has a portion that is flexible, the proximal end including an opening;
• a valve cap liquid-tightly attached to the opening of the bottle;
• a valve in fluid communication with the opening of the bottle;
• a dosing cap attached to the valve cap, including a closed end and an open end;
• and
• a venting aperture formed in the valve cap to allow air flow into and out of the dosing cap.

A dispensing attachment for a bottle, the dispensing attachment comprising:

• a dosing cap including a closed end and an open end;
• a valve cap attached to the dosing cap and configured to liquid-tightly attach to the opening of a bottle;
• and
• a valve assembly disposed on the valve cap, including:
• a valve body including a distal opening and a proximal opening;
• an outlet valve disposed adjacent to the proximal opening of the valve body;
• and
• a shut-off valve disposed in the valve body and movable between an open position and a closed position, wherein the shut-off valve is configured to open the distal opening of the valve body when the dispensing attachment is in an inverted position with the proximal opening disposed below the distal opening and to close the distal opening of the valve body when the dispensing attachment is in an upright position with the proximal opening disposed above the distal opening.
