Abstract: A pressurized gas cartridge drives a dispensing device for viscous product cartridges. The dispensing device and the viscous product cartridge form a gas enclosure separated from a product enclosure by a movable wall. A valve is driven by a rack and pinion valve drive mechanism between an open position and a closed position upon rotation of the pinion. The rack rotates the pinion upon linear movement thereof. A trigger is adapted to impart linear movement to the rack upon manual actuation of the trigger. The open position of the nozzle valve permits viscous product to flow through the dispensing passage, and the closed position of the nozzle valve prevents viscous product from flowing through the dispensing passage. The interface between the trigger and rack is designed to operationally disengage rather than transmit a force therebetween that is capable of damaging the device.

Abstract: A fountain for heating and distributing fluidic material is manufactured using various processes and materials so that the fountain is more easily cleaned and sanitized, has improved performance, and is easier to assemble. In one embodiment, the chocolate fountain includes a heating element encased in an aluminum enclosure. A basin containing chocolate is heated by contact with the aluminum enclosure. Because the aluminum enclosure has a relatively high thermal conductivity, the basin is heating substantially uniformly, thus reducing the occurrence of hot spots. Additionally, a plastic auger having a spiral flight rotates and lifts the melted chocolate upward to a top end of cylinder that houses the auger. The use of a plastic auger advantageously eliminates welding artifacts on the auger, such as burrs and pits, on which melted chocolate may accumulate. Accordingly, the plastic auger is easy to clean. A smaller chocolate fountain that may advantageously be more suitable for home use is also described herein.
