Abstract
Abstract A nozzle assembly for filling containers such as toothpaste tubes comprises inner and outer tubular members providing a core column of one fluent paste material separated from an annular column of a second fluent paste material, with the inner tubular casing being slotted for admitting streams of the second paste material peripherally into and along the core column before discharge from the nozzle assembly, as to produce a striped effect in the discharged composite product.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 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, resilient sealing means between the tubes at opposite ends for preventing fluent material from leaving said annular space except through said orifices and axially aligned material flow modifying means disposed upstream of said orifices.
Claim 2
Dependent Claim
156 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, resilient sealing means between the tubes at opposite ends for preventing fluent material from leaving said annular space except through said orifices and axially aligned material flow modifying means disposed upstream of said orifices.
Claim 3
Dependent Claim
154 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, 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, and axially aligned material flow modifying means disposed upstream of said orifices.
Claim 4
Dependent Claim
154 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, 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, and axially aligned material flow modifying means disposed upstream of said orifices.
Claim 5
Dependent Claim
17 words
The nozzle assembly of claim 1 including a plurality of spaced orifices in said inner tubular member.
Claim 6
Dependent Claim
14 words
The nozzle assembly of claim 2 wherein said plurality of orifices are evenly spaced.
Claim 7
Dependent Claim
15 words

Claim 8
Dependent Claim
17 words
The nozzle assembly defined in claim 1, wherein said hollow tubes are threadedly connected at one end.
Claim 9
Dependent Claim
29 words
The nozzle assembly of claim 2 wherein said flow modifying means comprises fixed internal projections on said inner tubular member adjacent the discharge end of each of said orifices.
Claim 10
Dependent Claim
22 words
The nozzle assembly of claim 7 wherein said projections are formed on an insert ring longitudinally fixed within said inner tubular member.
Claim 11
Dependent Claim
28 words
The nozzle assembly defined in claim 1, wherein said flow modifying means comprises fixed internal projections on said inner tubular member adjacent the discharge end of each orifice.
Claim 12
Dependent Claim
23 words
The nozzle assembly defined in claim 9, wherein said projections are formed on an insert ring longitudinally fixed within said inner tubular member.
