Abstract

A dispensing closure ( 40 ) for use with a container ( 44 ) includes a body ( 54 ) having a dispensing spout ( 72 ) with an interior surface ( 80 ) that defines at least a portion of a passage ( 132 ) for communicating with the container interior to permit the flow of a fluent substance through the body ( 54 ). The dispensing closure ( 40 ) includes a closing element ( 56 ) attached to the body ( 54 ). The closing element ( 56 ) defines a transverse cover ( 130 ) having a closed position relative to the body ( 54 ) and an actuated, open position relative to the body ( 54 ). The transverse cover ( 130 ) has an outwardly projecting toggle tab ( 58 ) for being engaged by a user to move the transverse cover ( 130 ) from the closed position to the actuated, open position. The transverse cover ( 130 ) further has a flexible, resilient cantilevered sealing portion ( 142 ) that seals against the interior surface ( 80 ) of the dispensing spout ( 72 ) with the transverse cover ( 130 ) located in the closed position.

First claim

What is claimed is:

1. A dispensing closure for use with a container having an opening between an exterior of the container and an interior of the container where a fluent substance may be stored, said dispensing closure comprising:
A. a body for being located at the opening of the container, said body having a dispensing spout defining an interior surface, said interior surface defining at least a portion of a passage for communicating with the container interior to permit the flow of a fluent substance through said body; and
B. a closing element attached to said body, said closing element defining
1. an outer wall mounted around at least a portion of said dispensing spout of said body, and
2. a transverse cover that extends laterally inwardly from said outer wall and that has a closed position relative to said body and an actuated, open position relative to said body, said transverse cover having
i. an outwardly projecting toggle tab for being engaged by a user to move said transverse cover from said closed position to said actuated, open position, and
ii. a flexible, resilient cantilevered sealing portion spaced laterally from said outer wall to
a. define an aperture for receiving said dispensing spout of said body, and
b. seal against said interior surface of said dispensing spout with said transverse cover located in said closed position, whereby when said toggle tab is engaged by a user to move said transverse cover to said actuated, open position, then said cantilevered sealing portion is moved away from said interior surface to expose said passage; wherein said dispensing spout of said body further comprises at least one pour lip for directing flow of a fluent substance out of said dispensing closure, said at least one pour lip extending outwardly from said interior surface and projecting laterally relative to said interior surface to define at least part of a pour path; and wherein said dispensing spout is substantially cylindrical and said at least one pour lip extends between about 20 degrees and about 30 degrees around a circumference of said dispensing spout.

2. A dispensing closure for use with a container having an opening between an exterior of the container and an interior of the container where a fluent substance may be stored, said dispensing closure comprising:
A. a body for being located at the opening of the container, said body having a dispensing spout defining an interior surface, said interior surface defining at least a portion of a passage for communicating with the container interior to permit the flow of a fluent substance through said body; and
B. a closing element attached to said body, said closing element defining
1. an outer wall mounted around at least a portion of said dispensing spout of said body, and
2. a transverse cover that extends laterally inwardly from said outer wall and that has a closed position relative to said body and an actuated, open position relative to said body, said transverse cover having
i. an outwardly projecting toggle tab for being engaged by a user to move said transverse cover from said closed position to said actuated, open position, and
ii. a flexible, resilient cantilevered sealing portion spaced laterally from said outer wall to
a. define an aperture for receiving said dispensing spout of said body, and
b. seal against said interior surface of said dispensing spout with said transverse cover located in said closed position, whereby when said toggle tab is engaged by a user to move said transverse cover to said actuated, open position, then said cantilevered sealing portion is moved away from said interior surface to expose said passage; wherein said transverse cover has
 i. at least one sealing bead having a normally closed configuration sealing against said interior surface of said dispensing spout when said transverse cover is located in said closed position, and
 ii. at least one wiping bead spaced axially-outwardly from said at least one sealing bead when said transverse cover is located in said closed position, said at least one wiping bead wiping against said interior surface of said dispensing spout when said transverse cover moves from said actuated, open position to said closed position; and wherein said dispensing spout of said body further comprises at least one pour lip for directing flow of a fluent substance out of said dispensing closure, said at least one wiping bead is variably spaced from said at least one sealing bead, and said at least one wiping bead is minimally spaced from said at least one sealing bead at a location proximal to said at least one pour lip.

3. A dispensing closure for use with a container having an opening between an exterior of the container and an interior of the container where a fluent substance may be stored, said dispensing closure comprising:
A. a body for being located at the opening of the container, said body having a dispensing spout defining an interior surface, said interior surface defining at least a portion of a passage for communicating with the container interior to permit the flow of a fluent substance through said body; and
B. a closing element attached to said body, said closing element defining
1. an outer wall mounted around at least a portion of said dispensing spout of said body, and
2. a transverse cover that extends laterally inwardly from said outer wall and that has a closed position relative to said body and an actuated, open position relative to said body, said transverse cover having
i. an outwardly projecting toggle tab for being engaged by a user to move said transverse cover from said closed position to said actuated, open position, and
ii. a flexible, resilient cantilevered sealing portion spaced laterally from said outer wall to
a. define an aperture for receiving said dispensing spout of said body, and
b. seal against said interior surface of said dispensing spout with said transverse cover located in said closed position, whereby when said toggle tab is engaged by a user to move said transverse cover to said actuated, open position, then said cantilevered sealing portion is moved away from said interior surface to expose said passage; wherein said transverse cover has
 i. at least one sealing bead having a normally closed configuration sealing against said interior surface of said dispensing spout when said transverse cover is located in said closed position, and
 ii. at least one wiping bead spaced axially-outwardly from said at least one sealing bead when said transverse cover is located in said closed position, said at least one wiping bead wiping against said interior surface of said dispensing spout when said transverse cover moves from said actuated, open position to said closed position; and wherein said body defines a central axis, said at least one sealing bead generally extends along a plane that is normal to said axis when said transverse cover is located in said closed position, and said at least one wiping bead extends along a generally arcuate path outwardly of said plane when said transverse cover is located in said closed position.

4. A dispensing closure for use with a container having an opening between an exterior of the container and an interior of the container where a fluent substance may be stored, said dispensing closure comprising:
A. a body for being located at the opening of the container, said body having a dispensing spout defining an interior surface, said interior surface defining at least a portion of a passage for communicating with the container interior to permit the flow of a fluent substance through said body; and
B. a closing element attached to said body, said closing element defining
1. an outer wall mounted around at least a portion of said dispensing spout of said body, and
2. a transverse cover that extends laterally
