Abstract

A dispensing apparatus adapted for dispensing a predetermined amount of one or more condiments or other fluids onto a sandwich or the like. The dispenser includes a stand supporting a nozzle which is connected in flow communication by conduits to at least one source of condiment. A valving arrangement and associated controllers are operatively connected to the conduits between the nozzle and the source of the condiment for selectively allowing a predetermined quantity of condiment to be dispensed through the nozzle.

Independent Claims | See all claims (10)

1. 1. A dispenser for dispensing a predetermined amount of condiment on a sandwich, said dispenser comprising:a source of condiment;a source of pressurized gas;first conduit means communicating with said source of condiment;a discharge means;second conduit means communicating with the discharge means;first valve means communicating with said first and second conduit means selectively connecting the first and second conduit means in flow communication for selective flow of condiment from the source to the discharge means, said first valve means including a first valve which is normally closed to prevent flow of condiment, said first valve being held normally closed at least partially by fluid pressure, said first valve means including a second valve operably associated with said first valve for selectively reducing said fluid pressure allowing said first valve to open;first control means operably connected to said second valve for selectively effecting opening and closing of said second valve, said first control means being operable for automatically regulating the amount of condiment dispensed to a predetermined amount, said first control means including a first actuator means operable for initiating operation of the first control means;third conduit means communicating with said source of pressurized gas;fourth conduit means communicating with said source of pressurized gas and said first valve to provide the fluid pressure to hold said first valve normally closed;fifth conduit means communicating with said discharge means;a third valve communicating with said third and fifth conduit means selectively connecting said third and fifth conduit means in flow communication, said third valve being operably connected to said first control means whereby said third valve is open when said first and second valves are open; anda stand having said discharge means and said first actuator means mounted thereon.
2. 6. A dispenser for dispensing a predetermined amount of condiment on a sandwich, said dispenser comprising:a source of condiment;first conduit means communicating with said source of condiment;a discharge nozzle;second conduit means communicating with said nozzle;first valve means communicating with the first and second conduit means selectively connecting the first and second conduit means in flow communication for selective flow of condiment from the source to the nozzle, said first valve means includes a first valve which is normally closed to prevent flow of condiment, said first valve being held normally closed at least partially by gas pressure, said first valve means including a second valve operably associated with said first valve for selectively reducing said gas pressure thereby allowing said first valve to open;first control means operably connected to said first valve means for selectively effecting connection of the first conduit means in flow communication with the second conduit means, said first control means being operable for automatically regulating the amount of condiment dispensed to a predetermined amount, said first control means including a first actuator means operable for initiating operation of the first control means, said first actuator means having an actuating portion adjacent said nozzle;a source of pressurized gas;third conduit means communicating with said source of pressurized gas;fourth conduit means communicating with said source of pressurized gas and said first valve to provide the gas pressure to hold said first valve normally closed;fifth conduit means communicating with said discharge means;a third valve communicating with said third and fifth conduit means selectively connecting said third and fifth conduit means in flow communication, said third valve being operably connected to said first control means whereby said third valve is open when said first and second valves are open; anda shield positioned adjacent said nozzle to locate a sandwich relative to said nozzle and prevent overspray of condiment.
