The valve holder/presenter, made from a rigid injectionmoulded plastic material, consists of at least one supporting panel (2) with a series of orifices (21) to receive individual valve stems, at least some of the orifices having raised surrounds (211) that hold the valves (1) at two or more different levels. The orifices are arranged so that alternating valves are at different heights, and the lower orifices have surrounds (212) that raise the valves just above the level of the panel. The orifice surrounds, especially on the lower level, have extensions (213) that act as guides for the valve stems and help to keep them vertical when the panels are positioned horizontally. The panels are made in one piece with rims (3) that extend downwards to a depth equivalent to the length of the valve stems and are shaped to allow panels to be stacked on top of one another. They also have lengthwise and transverse reinforcing ribs (23) and holes for draining cleaning fluid. |
