ABSTRACT:
Two dispensing cylinders are secured in side-by-side relation and have pistons whose rods protrude through one end of the cylinders and are yoked together outside the package. A threaded nut is formed in that one end of the package, between the cylinders, and receives a threaded operator. The operator protrudes through an opening in the yoke, which provides a bearing, and is equipped with a handwheel. As the handwheel is turned, the threaded rod is pulled through the nut, consequently advancing both pistons. The threaded rod enters a pocket between the cylinders and the pistons and piston rods are not required to rotate as they are advanced. The package is preferably marked to correlate the amount of product dispensed with the extent of turning of the handwheel.
