  • Fig. 26C may illustrate another position of the mechanism, where the cam 2620 may be in another stable position.
  • One of the key factors of the invention shown in Fig. 26A-26C is the fact that the cam 2614 may be in two stable positions.
  • insulation layer 2606 This provides a stable open and closed position of insulation layer 2606, 'closed' with respect to food opening 2402 when actuated 'down', and 'open' with respect to food opening 2402 when the cam position pulls insulation layer 2606 'up' so that the insulation canister 2404 can rotate freely on the carousel.
  • the insulation canister may be operated by the same motor/cam system as the normal food dispensing operation.
  • Fig. 27 illustrates an embodiment of this invention, wherein ingredients sticking to the walls of the ingredient container/canister may be reduced by using fittings 2704 within the canister. These fittings may be actuated by motion of the paddles 2710.
  • the fittings 2704 may be attached to the top of canisters 2708 or the sides of canisters 2709. They may have multiple pieces, for example, with one portion fitting bottom 2707 contacting the paddle and another portion fitting top 2704 contacting top of canisters 2708.
  • the paddle rotates, it may move the fittings back and forth by contacting fitting bottom 2707 and causing motion within the canister which may allow ingredients stuck to the sides of canisters to come unstuck.
