Abstract
A plurality, e.g., two, fluid product-containing cylinders are joined, side-by-side in a body, with their dispenser spouts adjoining one another. An operator assembly is fitted on the opposite end of the body and unites a cap, an operator, such as a handwheel, a helically threaded rod for each cylinder, a piston mounted on each rod for longitudinal travel upon rotation of the rod, a gear plate receiving a set of gears which interconnect the threaded rods with the operator, so that as the operator is turned, the pistons are advanced. Several assembly aids are shown. A variation is shown, wherein the situs of the spouts is displaced to an intermediate location on the front face of the body, so the body can be footed and thus supported upright, e.g., for use as a condiment dispenser. Most of the principles of the invention are equally applicable to dispensers having only one chamber.
