Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
313 words
A nozzle for dispensing a pastelike product and adapted to be secured to the opened end of a product container, comprising: an elongated, flat and hollow dispensing portion having an opening therethrough, said dispensing portion having a width greater than its thickness and having a longitudinal length at least equal to its width; said dispensing portion having an elongated and narrow discharge orifice at one end thereof communicating with said opening, said opening adjacent the other end of said dispensing portion being substantially circular with said opening as it extends from said other end to said one end being of a gradually modified cross section with the opening smoothly and gradually flattening and widening as it extends from said other end toward said discharge orifice; said discharge orifice having an area less than the area of the circular portion of said opening adjacent said other end of said dispensing portion, and said discharge orifice having a width greater than the diameter of the circular portion of said opening; a short, radially enlarged connector portion integrally connected to said dispensing portion adjacent said other end thereof, said connector portion being adapted to engage the opened end of said container, said connector portion having a substantially circular passage therethrough in communication with the circular portion of said opening; and a removable cap mountable on said one end of said dispensing portion of for sealingly closing said discharge orifice, said cap including a body portion adapted to be disposed directly adjacent said one end of said dispensing portion and a tonguelike projection extending outwardly from said body portion, said tonguelike projection having an enlargement having a width greater than the width of said discharge orifice, and at least the discharge end of said dispensing portion being elastically deformable for permitting said enlargement to pass through said discharge orifice for effecting a sealed closing of said opening.

A nozzle for dispensing a pastelike product and adapted to be secured to the opened end of a product container, comprising: an elongated, flat and hollow dispensing portion having an opening therethrough, said dispensing portion having a width greater than its thickness and having a longitudinal length at least equal to its width; said dispensing portion having an elongated and narrow discharge orifice at one end thereof communicating with said opening, said opening adjacent the other end of said dispensing portion being substantially circular with said opening as it extends from said other end to said one end being of a gradually modified cross section with the opening smoothly and gradually flattening and widening as it extends from said other end toward said discharge orifice; said discharge orifice having an area less than the area of the circular portion of said opening adjacent said other end of said dispensing portion, and said discharge orifice having a width greater than the diameter of the circular portion of said opening; a short, radially enlarged connector portion integrally connected to said dispensing portion adjacent said other end thereof, said connector portion being adapted to engage the opened end of said container, said connector portion having a substantially circular passage therethrough in communication with the circular portion of said opening; and a removable cap mountable on said one end of said dispensing portion of for sealingly closing said discharge orifice, said cap including a body portion adapted to be disposed directly adjacent said one end of said dispensing portion and a tonguelike projection extending outwardly from said body portion, said tonguelike projection having an enlargement having a width greater than the width of said discharge orifice, and at least the discharge end of said dispensing portion being elastically deformable for permitting said enlargement to pass through said discharge orifice for effecting a sealed closing of said opening.
Claim 3
Dependent Claim
31 words
A nozzle according to claim 1, wherein said body portion of said cap has a cross-sectional configuration approximately corresponding to the external configuration of said one end of said dispensing portion.
Claim 4
Dependent Claim
26 words
A nozzle according to claim 1, wherein said circular passage is threaded for permitting said nozzle to be secured to a container containing a pastelike product.
