Abstract: A receptacle for receiving a supply bottle in a bottled water dispenser includes a bottle support member having an annular rim for supporting the supply bottle in an inverted mounted position. The support member has a downwardly depending funnel portion for receiving the bottle neck, the neck having a closure cap. The funnel portion has a bottom wall portion with an opening therein. Water in the funnel portion received from the bottle passes through this opening to be dispensed by the dispenser. A piercing probe extends upwardly from the bottom wall portion to pierce the cap on the water bottle neck. The piercing probe is non-tubular and has at least one longitudinal exterior groove to allow water to pass from the bottle neck into the funnel portion.
