Claim 1:
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.
