Abstract: The dispensing appliance customarily built in "pistol form" for double cartridges with plunger has a pressure medium-driven cylinder/piston unit with rams extending from the piston for the forward drive of the plungers. The problem here consists in that during the piston forward thrust the reaction forces from the plungers acting upon the rams can be very different (different viscosities of the substances contained in the two cartridge cylinders and/or different cross-sections of the cartridge cylinders). In order to prevent "tilting" or jamming of the piston, the invention provides in a cylinder space a rigid longitudinal guide between both cylinder floors against which the piston is slidingly supported with a longitudinally extended guide bore. The longitudinal guide can simultaneously reinforce the cylinder and further lead the pressure medium into the pressure chamber behind the piston by way of a longitudinal channel.

Abstract: A dispensing package for cosmetic cream products which automatically and progressively indicates when the product has nearly been depleted by the user. The package includes a deformable fin cantilevered from the piston which contacts the underside of the wall on which applicating surface is formed and is thereby bent in the direction of an orifice in the applicating surface. Further advance of the piston causes the fin to progressively cross the orifice, becoming visible from the exterior. As the piston is further advanced towards the applicating surface, continued deformation of the fin causes it to advance fully across the orifice, thereby indicating to the user that the cream product is nearly depleted. The invention is well suited to dispensing packages which contain and dispense cream deodorants and antiperspirants.
