  • Patent number: 4274556
    Abstract: A one-piece housing defines a pair of laterally separated chambers for containing liquids to be dispensed. A pair of hollow filler necks extend upwardly from the top wall of the housing for communication each with a different one of the chambers for filling the latter with a liquid, and a carrying handle is secured to and extends laterally between said necks. A squeeze bulb type pump associated with each chamber has an intake pipe extending into the chamber and is removably closed by a ball check valve. A flexible outlet dispenser tube extends from the valve body and is fitted at its outer end with a check valve for allowing flow of liquid only in the outfeed direction. The ball check is moved from the closed position by partial vacuum created by expansion of the bulb following squeezing, and the ball check is closed during collapsing of the bulb as it is squeezed.
