Abstract
An automatically operated soap dispenser for use in washing the hands of a user is provided in a housing. Enclosed in an intermediate portion of the housing is a horizontally disposed transparent cylindrical chamber having an open front end and an opening in the upper wall thereof. Residing in the upper portion of the housing is a disposable liquid soap container having extending from the bottom thereof a resilient elongated tubular member with a self-sealing nipple valve on the lower end thereof which is positioned in the opening on the upper wall of the cylindrical chamber. A cyclically operated actuating means located in the housing above the cylindrical chamber is controlled to automatically squeeze the tubular member and supply a single quantity of liquid soap through the nipple valve in response to an upturned palm of a hand of the user being inserted into the open front of the cylindrical chamber.
