Abstract: A fluid dispenser is extruded from a low density polyethylene material and moulded under pressure to form a body which comprises a bellows closed at one end and including at its other end an upstanding open-ended neck portion formed with external screw threads. The bellows comprises a plurality of vertically spaced ring-shaped outer fold-lines and a plurality of vertically spaced inner ring-shaped fold-lines of smaller diameter than that of the outer fold-lines. Each inner ring-shaped fold-line is positioned at a height generally midway between each pair of outer fold-lines, and annular webs extend between neighbouring inner and outer fold-lines. The mean thickness of the webs is between 0.4 and 1.55 mm, the height of the dispenser is between 55 and 85 mm and the weight of the dispenser is between 10 and 17.5 grams.
