Abstract
Abstract A unit for electrically heating and dispensing products from pressurized containers. The unit receives a pressurized container, and, upon actuation of the container valve, directs the product through a series of passages, including one or more heating chambers, steam traps, and the like, to the outlet openings from which the product is dispensed. Depending on the predetermined configuration of the openings in the dispensing nozzle of an associated product container, the dispenser is adapted to direct the product into one or more heating chambers alternatively, or into two or more chambers simultaneously. Each heating chamber is formed in part by an exterior surface of a relatively massive heat sink unit having an electrical resistance heating element associated therewith and controlled by an adjustable thermostat. Electric current is supplied to the element and the control through a connector which affords mechanical strength, electrical insulation and which provides a water-tight connection. The passages directing the product to one or more of the heat exchangers are located within a cover element closely overlying the heat sink and the thermostat. Since typical products dispensed by the novel unit are highly viscous, the containers thereof should be stored in the inverted position and accordingly, containers are constructed so as to facilitate inverted storage and to prevent unintentional upright storage.
