Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
158 words
A pouring nozzle particularly constructed for use in combination with a container spout, said pouring nozzle comprising an elongated tube having an upper end closure and an open lower end, at least one lateral fluid passage in said tube adjacent said upper end closure, and means on said tube for selected interlocking with a container spout in a dispensing position and a container spout closing position, a container spout telescopically receiving said tube, said container spout having axially outer means for engagement with said tube interlocking means in a recessed position of said tube and axially inner means for engagement with said tube interlocking means in a projecting dispensing position of said tube, said container spout having an internal throat intermediate said inner and outer means, and said throat having a cross section substantially corresponding to the cross section of said tube and closely fitting said tube while permitting sliding movement of said tube through said container spout.
Claim 2
Dependent Claim
158 words
A pouring nozzle particularly constructed for use in combination with a container spout, said pouring nozzle comprising an elongated tube having an upper end closure and an open lower end, at least one lateral fluid passage in said tube adjacent said upper end closure, and means on said tube for selected interlocking with a container spout in a dispensing position and a container spout closing position, a container spout telescopically receiving said tube, said container spout having axially outer means for engagement with said tube interlocking means in a recessed position of said tube and axially inner means for engagement with said tube interlocking means in a projecting dispensing position of said tube, said container spout having an internal throat intermediate said inner and outer means, and said throat having a cross section substantially corresponding to the cross section of said tube and closely fitting said tube while permitting sliding movement of said tube through said container spout.
Claim 3
Dependent Claim
51 words
The pouring nozzle of claim 1 wherein said container spout is internally enlarged above said throat and said enlargement is aligned with said lateral fluid passage in the container spout closing position of said tube for the return of a product from the exterior of said tube following a dispensing operation.
Claim 4
Dependent Claim
15 words
The pouring nozzle of claim 1 wherein said container spout is of a resilient construction.
Claim 5
Dependent Claim
47 words
The pouring nozzle of claim 1 wherein said container spout has an axially outward facing shoulder above said throat, and said upper end closure extends laterally beyond said tube and defines peripheral collar means for seating on said shoulder in the container closing position of said tube.
Claim 6
Dependent Claim
51 words
The pouring nozzle of claim 1 wherein said interlocking means of said tube includes a peripheral shoulder on the exterior of said tube adjacent the lower end of said tube, and said shoulder has a cross section substantially corresponding to the cross section of said throat at a lower end thereof.
Claim 7
Dependent Claim
140 words
In a container For dispensing a liquid including an aperture in an end closure adapted to receive a pouring nozzle in extended and recessed positions a one-piece container spout for the container comprising: means on its outer surface for securing the container spout in the aperture, a throat extending generally axially therethrough, a diaphragm sealing off the throat and adapted to be broken in order to receive a pouring nozzle, first means for sealingly engaging complementary means on the pouring nozzle in its extended position, said first means being disposed in the throat on the side of the diaphragm adapted to face the interior of the container, and second means for sealingly engaging complementary means on the pouring spout in said recessed position, said means being disposed on the side of the diaphragm adapted to face outwardly from the container.
Claim 8
Dependent Claim
140 words
In a container For dispensing a liquid including an aperture in an end closure adapted to receive a pouring nozzle in extended and recessed positions a one-piece container spout for the container comprising: means on its outer surface for securing the container spout in the aperture, a throat extending generally axially therethrough, a diaphragm sealing off the throat and adapted to be broken in order to receive a pouring nozzle, first means for sealingly engaging complementary means on the pouring nozzle in its extended position, said first means being disposed in the throat on the side of the diaphragm adapted to face the interior of the container, and second means for sealingly engaging complementary means on the pouring spout in said recessed position, said means being disposed on the side of the diaphragm adapted to face outwardly from the container.
