  • Patent number: 5409140
    Abstract: A dispenser for dispensing two components is disclosed which comprises a drum 10 in which a tube 20 is supported. A first piston 12 is arranged within the drum 10 and has an opening 22 through which the tube 20 extends. The opening is provided with a plug 80 which has an aperture also through which the tube 20 extends. The plug supports a blade 32 which bears on a second piston 40 arranged within the tube 22. The plug 80 is fixed relative to the piston 12 so that it and the blade 32 move with the piston 12. During movement of the piston 12 the blade 32 slices the tube 20 and bears against the second piston 40 so that the first piston 12 and the second piston 40 move in a fixed manner as a single unit. During movement of the pistons 12 and 40 the two components are dispensed from the drum 10 and the tube 22 in a particular ratio depended upon the volume displaced by movement of the pistons 12 and 40. The dispensed components can therefore be mixed together in the predetermined ratios.

  • Patent number: 5398845
    Abstract: A dispenser for soap lather has a vessel for a larger supply of liquid soap and a tank for a smaller supply of liquid soap and for a body of air above the smaller supply. One or more bellows are used to pump compressed air into a portion of the tank when a user desires to obtain a batch of lather. The compressed air expels a certain quantity of liquid soap from the tank into a lather generator and the lather generator further receives some compressed air to form a batch of lather which is dispensed into or onto the hands of a user. When the bellows expands or expand, it or they can draw air into or along the outlet of the lather generator to retract any remnants of lather. Alternatively, a discrete pump can be provided to blow out any remnants from the lather generator in response to or during expansion of the bellows. The discharged quantity of liquid soap is replenished in the tank by way of an adjustable conduit connecting the vessel with the tank.
