    Patent number: 6701828
    Abstract: An apparatus that dispenses a food substance has a housing and a barrel removably connected to the housing. A rod connected to a plunger is disposed within the housing and the barrel. A drive mechanism including a dual-direction electric motor is located in the housing. The drive mechanism actuates the rod so that the plunger is advanced in the barrel to dispense the food substance. The drive mechanism includes a nut housing having an inner passage housing a nut positioned between a pair of compression springs.
