ABSTRACT:
A slide dispensing cap and dispensing stopper for a dispensing bottle which includes a one-way valve between the interior of the bottle and the cap so that air cannot enter into the bottle when product is dispensed through a tube because the valve closes to prevent product from passing through the one-way valve. A tube communicates with the stopper and in a dispensing position of the slide nozzle so that product can pass out through the nozzle. After dispensing the bottle is released and air can enter the bottle through the one-way valve.
