Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 145 words
A nozzle assembly for filling containers with fluent materials arranged in desired composite relation comprising longitudinally coextensive inner and outer tubular members removably secured together to form an annular space therebetween, said tubular members being threadedly connected at one end, means for introducing a first fluent material into one end of the inner tubular member, means forming a discharge opening at the other end of said inner tubular member, said inner tubular member having an enlarged portion adjacent its other end slidably fitting within the outer tube, means for introducing a second fluent material into said space, means providing a plurality of spaced orifices in said inner tubular member providing communication between said space and the interior of said inner tubular member, and resiliant sealing means between the tubes at opposite ends for preventing fluent material from leaving said annular space except through said orifices.
Claim 2
Dependent Claim 145 words
A nozzle assembly for filling containers with fluent materials arranged in desired composite relation comprising longitudinally coextensive inner and outer tubular members removably secured together to form an annular space therebetween, said tubular members being threadedly connected at one end, means for introducing a first fluent material into one end of the inner tubular member, means forming a discharge opening at the other end of said inner tubular member, said inner tubular member having an enlarged portion adjacent its other end slidably fitting within the outer tube, means for introducing a second fluent material into said space, means providing a plurality of spaced orifices in said inner tubular member providing communication between said space and the interior of said inner tubular member, and resiliant sealing means between the tubes at opposite ends for preventing fluent material from leaving said annular space except through said orifices.
Claim 3
Dependent Claim 143 words
A nozzle assembly for filling containers with fluent materials arranged in desired composite relation comprising inner and outer tubular members secured together to form an annular space therebetween, means for introducing a first fluent material into one end of the inner tubular member, means forming a discharge opening at the other end of said inner tubular member, means for introducing a second fluent material into said annular space, means providing at least one orifice in said inner tubular member, said orifice providing communication between said annular space and the interior of said inner tubular Member, and sealing means at opposite ends of said tubes for preventing fluent material from leaving said annular space except through said orifice, said sealing means including an enlarged portion of said inner tubular member adjacent said other end and said orifice, said enlarged portion terminating said annular space.
Claim 4
Dependent Claim 143 words
A nozzle assembly for filling containers with fluent materials arranged in desired composite relation comprising inner and outer tubular members secured together to form an annular space therebetween, means for introducing a first fluent material into one end of the inner tubular member, means forming a discharge opening at the other end of said inner tubular member, means for introducing a second fluent material into said annular space, means providing at least one orifice in said inner tubular member, said orifice providing communication between said annular space and the interior of said inner tubular Member, and sealing means at opposite ends of said tubes for preventing fluent material from leaving said annular space except through said orifice, said sealing means including an enlarged portion of said inner tubular member adjacent said other end and said orifice, said enlarged portion terminating said annular space.
Claim 5
Dependent Claim 17 words
The nozzle assembly of claim 2 including a plurality of spaced orifices in said inner tubular member.
Claim 6
Dependent Claim 14 words
The nozzle assembly of claim 3 wherein said plurality of orifices are evenly spaced.
Claim 7
Dependent Claim 15 words
The nozzle assembly defined in claim 2, wherein said tubular members are longitudinally coextensive tubes.
Claim 8
Dependent Claim 17 words
The nozzle assembly defined in claim 5, wherein said hollow tubes are threadedly connected at one end.
