<p>A dispenser with a collapsible bottle (10) and a valve assembly for the throat of the bottle is disclosed. The valve assembly (18) includes a first hollow valve section to be sealed in the throat of the bottle and an elongate, hollow second valve section having apertures in the side wall. The second valve section telescopes in the first section between a closed position so that the apertures are located within the channel of the first valve section to close the bottle and an open position where the apertures are in flow communication with the interior of the bottle (10). The first and second valve sections are dimensioned to receive an elongate probe forming part of a dispenser pump mechanism. The plastic bottle (10) is provided with crease lines (12, 13) located on the front, back and sides so the bottle collapses as liquid is pumped out of the bottle to prevent exposure of the liquid contents to air.</p> |
