Abstract
A food dispenser gun, comprising a tube holding a quantity of an extrudable food product, a piston sealingly engaged with an interior of the tube, a rod coupled to the piston and an incremental dispenser engaged with the rod and the tube, the incremental dispenser comprising a trigger, or an advancement lever operable to move the rod in a first direction relative to the incremental dispenser in response to the trigger and a retrograde lock operable to prevent the rod from moving in a second direction, wherein the advancement lever and the retrograde lock are completely enclosed by a housing of the incremental dispenser. Other systems, devices and methods are disclosed.
Claims24
A food dispenser gun, comprising:
- a housing;
- a removable and reusable container to hold a quantity of an extrudable food product said removable and reusable container removably engaged with said housing;
- a piston sealingly engaged with an interior of said removable and reusable container;
- a rod coupled to said piston;
- and
- an incremental dispenser engaged with said rod and said removable and reusable container, said incremental dispenser comprising:
- a manual activator;
- a member operable to move said rod in a first direction relative to said incremental dispenser in response to said manual activator;
- and
- a retrograde lock operable to prevent said rod from moving in a second direction;
- wherein said advancement means and said retrograde lock are completely enclosed by said housing of said incremental dispenser.
8 more elements
A food dispenser gun, comprising:
- a food
- a tube adapted to hold said food;
- a piston sealingly engaged with an interior of said tube;
- a rod coupled to said piston;
- and
- an incremental dispenser engaged with said rod and said tube, said incremental dispenser comprising:
- a pistol grip with trigger wherein depression of said trigger is operative to activate said incremental dispenser;
- advancement means operable to move said rod in a first direction relative to said incremental dispenser in response to said trigger depression, said advancement means comprising:
- a lever having an opening therethrough for passage of said rod, said opening being slightly larger than a cross-sectional dimension of said rod;
- a distal end of said lever being attached to said trigger;
- said lever pivoting against a first fixed guide at a point near a proximal end of said lever in response to said trigger depression;
- and
- said pivoting causing said opening to bind against said rod and move said rod in said first direction;
- and
- a retrograde lock operable to prevent said rod from moving in a second direction;
- wherein said advancement means and said retrograde lock are completely enclosed by a housing of said incremental dispenser.
13 more elements
A food dispenser gun, comprising:
- a tube adapted to receive a quantity of food;
- a first extrusion cap and a second extrusion cap, wherein either said first extrusion cap or said second extrusion cap is coupled to a distal end of said tube and said first extrusion cap includes a first extrusion opening and said second extrusion cap includes a second extrusion opening, said first extrusion opening having a different shape than said second extrusion opening for extruding said food into an appropriate shape therethrough;
- a piston sealingly engaged with an interior surface of said tube, said piston and said extrusion means defining a food holding chamber therebetween;
- a rod coupled to said piston;
- and
- an incremental dispenser engaged with said rod and said tube, said incremental dispenser comprising:
- manual activation means;
- advancement means operable to move said rod in a first direction relative to said incremental dispenser in response to said manual activation means;
- and
- a retrograde lock operable to prevent said rod from moving in a second direction;
- wherein said advancement means and said retrograde lock are completely enclosed by a housing of said incremental dispenser.
