Abstract
Abstract A generally annular pouring fitment is forced into a closure, thereby deforming a lip of the fitment elastically and inelastically. The closure is then releasably secured to a container causing the fitment to permanently interlock with the container. When the closure is removed, the lip defines a pouring surface of a desired three-dimensional configuration.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
86 words
A method of making and installing a pouring fitment comprising: forming a generally annular fitment having a retainer portion and a lip; forcing said fitment into a closure and thereby deforming said lip to form a pouring surface thereon, part of said deformation being elastic and part of said deformation being inelastic, whereby said lip defines a pouring surface of a desired three-dimensional configuration when separated from said closure; and releasably securing said closure to a container and thereby permanently installing said fitment on said container.
Claim 2
Independent Claim
86 words
A method of making and installing a pouring fitment comprising: forming a generally annular fitment having a retainer portion and a lip; forcing said fitment into a closure and thereby deforming said lip to form a pouring surface thereon, part of said deformation being elastic and part of said deformation being inelastic, whereby said lip defines a pouring surface of a desired three-dimensional configuration when separated from said closure; and releasably securing said closure to a container and thereby permanently installing said fitment on said container.
Claim 3
Dependent Claim
14 words

Claim 5
Independent Claim
81 words
A method of making and installing a pouring fitment comprising: forming a generally annular fitment having a retainer portion, a ring extending upwardly from said retainer portion and a lip extending from said ring; forcing said fitment into a closure and thereby deforming said lip to form a pouring surface thereon, part of said deformation being elastic and part of said deformation being inelastic; and releasably securing said closure to a container and thereby permanently installing said fitment on said container.
Claim 6
Independent Claim
81 words
A method of making and installing a pouring fitment comprising: forming a generally annular fitment having a retainer portion, a ring extending upwardly from said retainer portion and a lip extending from said ring; forcing said fitment into a closure and thereby deforming said lip to form a pouring surface thereon, part of said deformation being elastic and part of said deformation being inelastic; and releasably securing said closure to a container and thereby permanently installing said fitment on said container.
Claim 7
Dependent Claim
14 words
The method of claim 4 wherein said fitment is formed of plastic by molding.
Claim 8
Dependent Claim
23 words
The method of claim 4 wherein said closure is secured to said container by rotating it and thereby threading it onto said container.
Claim 9
Dependent Claim
22 words
The method of claim 4 wherein said lip is deformed by forcing it axially into an annular cradle defined by said closure.
Claim 10
Dependent Claim
32 words
The method of claim 4 wherein said lip is deformed by forcing it upwardly and axially into an annular cradle defined by said closure and thereby bending said lip outwardly and downwardly.
Claim 11
Dependent Claim
31 words
The method of claim 4 comprising the further step of removing said closure from said container, whereby said lip is caused to define a pouring surface of a desired three-dimensional configuration.
Claim 12
Independent Claim
93 words
A method of making and installing a pouring fitment comprising: forming a fitment having a retainer portion defining an annular recess, a ring extending upwardly from said retainer portion and a lip extending from said ring; forcing said fitment into a closure and thereby deforming said lip to form a pouring surface thereon, part of said deformation being elastic and part of said deformation being inelastic; and releasably securing said closure to a container and thereby elastically deforming said retainer portion to interlock with a holding portion of said container in said recess.
Claim 13
Independent Claim
93 words
A method of making and installing a pouring fitment comprising: forming a fitment having a retainer portion defining an annular recess, a ring extending upwardly from said retainer portion and a lip extending from said ring; forcing said fitment into a closure and thereby deforming said lip to form a pouring surface thereon, part of said deformation being elastic and part of said deformation being inelastic; and releasably securing said closure to a container and thereby elastically deforming said retainer portion to interlock with a holding portion of said container in said recess.
Claim 14
Dependent Claim
14 words
The method of claim 10 wherein said fitment is formed of plastic by molding.
Claim 15
Dependent Claim
23 words
The method of claim 10 wherein said closure is secured to said container by rotating it and thereby threading it onto said container.
Claim 16
Dependent Claim
22 words

Independent Claim
125 words
A method of making and installing a pouring fitment comprising: forming a generally annular fitment having a retainer portion, a ring extending upwardly from said retainer portion, a lip extending from said ring, and a radially outwardly extending flexible foot; forcing said fitment into a closure, thereby deforming said lip to form a pouring surface thereon, part of said deformation being elastic and part of said deformation being inelastic, and causing said foot to temporarily retain said fitment in said closure; releasably securing said closure to a container and thereby permanently installing said fitment on said container; and removing said closure from said container, thereby separating said closure from said fitment and causing said lip to define a pouring surface of a desired three-dimensional configuration.
Claim 20
Independent Claim
