Abstract
A dispenser comprises a collapsible bottle and a valve assembly for placement in the throat of the bottle which includes a first hollow valve member sealed in the throat of the bottle and a hollow second valve member having apertures in the side wall. The second valve member telescopes in the first valve member between a closed position in which the apertures are located within the channel of the first valve member to close the bottle and an open position in which the apertures are in flow communication with the interior of the bottle. The first and second valve members are dimensioned to receive a probe forming part of a dispenser pump mechanism. The bottle is provided with crease lines located on the front, back and sides so that the bottle collapses as liquid is pumped out of the bottle to prevent exposure of the liquid contents to air.
