Abstract
Abstract A rupturable diaphragm seal is disclosed for use in dispensing closures having a closure body including a dispensing opening leading there through and having a spout rotatably mounted on the body so as to be capable of being rotated from an initial closed position in which a passage in the spout is out of alignment with the dispensing opening to an open position in which the passage of the spout is aligned with the dispensing opening. In such a closure the rupturable diaphragm is secured to the closure body so as to extend across the opening. The spout used is formed so as to overlie the diaphragm in an initial closed position of the spout and is formed so as to engage and apply pressure to the diaphragm when the spout is rotated from this initial closed position to an open position so as to rupture the diaphragm.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
292 words
In a dispensing closure having a closure body, said body including a dispensing opening leading from one side to the other side of said body, and having a spout rotatably mounted on said body, said spout including a base overlying said opening and a passage extending from said base through said spout, said spout being capable of being rotated from an initial closed position in which said passage is unaligned with said opening to an open position in which said passage is aligned with said opening, the improvement which comprises: said closure body having a diaphragm extending across said opening in said body so as to close said opening; said diaphragm being capable of being ruptured by the application of pressure to it; the base of said spout being shaped so that the surface of said base overlies, but does not apply pressure to, said diaphragm when said spout is in said initial closed position; said base of said spout being shaped so that said surface is closer to the axis of rotation of said spout than the portion of said spout around said passage in said base so that as said spout is rotated from an initial closed position to said open position said base will engage said diaphragm so as to apply pressure in order to rupture said diaphragm. said body and said diaphragm being integral with one another and are formed of a material which is flexible and resilient, but which is capable of being broken when present in a thin crosssection, and flexible, resilient sealing ring means located on said closure body around said opening, said sealing ring means engaging the base of said spout so as to form a seal therewith in said open and closed positions.
Claim 2
Dependent Claim
292 words
In a dispensing closure having a closure body, said body including a dispensing opening leading from one side to the other side of said body, and having a spout rotatably mounted on said body, said spout including a base overlying said opening and a passage extending from said base through said spout, said spout being capable of being rotated from an initial closed position in which said passage is unaligned with said opening to an open position in which said passage is aligned with said opening, the improvement which comprises: said closure body having a diaphragm extending across said opening in said body so as to close said opening; said diaphragm being capable of being ruptured by the application of pressure to it; the base of said spout being shaped so that the surface of said base overlies, but does not apply pressure to, said diaphragm when said spout is in said initial closed position; said base of said spout being shaped so that said surface is closer to the axis of rotation of said spout than the portion of said spout around said passage in said base so that as said spout is rotated from an initial closed position to said open position said base will engage said diaphragm so as to apply pressure in order to rupture said diaphragm. said body and said diaphragm being integral with one another and are formed of a material which is flexible and resilient, but which is capable of being broken when present in a thin crosssection, and flexible, resilient sealing ring means located on said closure body around said opening, said sealing ring means engaging the base of said spout so as to form a seal therewith in said open and closed positions.
Claim 3
Dependent Claim
140 words
A dispensing closure as claimed in claim 1 wherein: said diaphragm is flat and includes scored lines extending across said opening, said scored lines defining areas of said diaphragm which are weaker than other areas of said diaphragm so that said diaphragm will rupture along said scored lines, the portion of the base of said spout shaped so as to overlie said diaphragm from when said spout is in said initial said closed position is flat, the remainder of the base of said spout shaped so as to engage and apply pressure to said diaphragm is spherical so as to engage the periphery of said diaphragm in order to push the segments of said diaphragm separated by said scored lines away from the center of said opening when said diaphragm is ruptured and said spout is in said open position.
Claim 4
Dependent Claim
50 words
A dispensing closure as claimed in claim 2 including: a scored area extending around the periphery of said diaphragm adjacent to said opEning, said scored area being thicker than said scored lines so as to be capable of acting as hinges when said diaphragm is broken along said scored lines.
Claim 5
Dependent Claim
190 words
In a dispensing closure having a closure body, said body including a dispensing opening leading from one side to the other side of said body, and having a spout rotatably mounted on said body, said spout including a base overlying said opening and a passage extending from said base through said spout, said spout being capable of being rotated from an initial closed position in which said passage is unaligned with said opening to an open position in which said passage is aligned with said opening, the improvement which comprises: said closure body having a flat diaphragm extending across said opening in said body so as to close said opening, the base of said spout having a flat portion shaped so as to overlie said diaphragm when said spout is in said initial closed position, said base of said spout other than said flat portion being the shape of a surface of revolutions, said base of said spout being shaped so as to engage and apply pressure to said diaphragm so as to rupture said diaphragm when said spout is rotated from said initial closed position to said open position.
Claim 6
Dependent Claim
190 words
In a dispensing closure having a closure body, said body including a dispensing opening leading from one side to the other side of said body, and having a spout rotatably mounted on said body, said spout including a base overlying said opening and a passage extending from said base through said spout, said spout being capable of being rotated from an initial closed position in which said passage is unaligned with said opening to an open position in which said passage is aligned with said opening, the improvement which comprises: said closure body having a flat diaphragm extending across said opening in said body so as to close said opening, the base of said spout having a flat portion shaped so as to overlie said diaphragm when said spout is in said initial closed position, said base of said spout other than said flat portion being the shape of a surface of revolutions, said base of said spout being shaped so as to engage and apply pressure to said diaphragm so as to rupture said diaphragm when said spout is rotated from said initial closed position to said open position.
Claim 7
Dependent Claim
16 words
A dispensing closure as claimed in claim 4 wherein: said surface of revolution is a sphere.
Claim 8
Dependent Claim
