Claim 11

The blank according to claim 7 wherein said second pour spout forming panel includes a central portion and spout sidewall forming means on opposite sides thereof for pivotal movement with respect to said central portion to define spout sides extending out of the plane of said central portion.

Claim 12

The blank according claim 8 wherein said second panel portion includes means positioned for alignment with said sidewall forming means for engagement therewith to effect pivoting thereof with respect to said central portion.

Claim 13

The blank according to claim 7 wherein said second pour spout forming panel includes means defined by a cut line in said second panel portion and aligned with said first pour spout forming panel for joinder thereto for frictionally engaging said second panel portion along edges formed by said cut line to maintain said first and second pour spout forming panels in closed position upon reclosing of the completed carton.

Claim 14

A carton blank for use in forming a carton having a pivotal pour spout and including first and second panel portions adapted to be aligned in overlapping relation, a first pour spout forming panel defined in said first panel portion by a first cut line terminating at each end thereof proximate a first fold line pivotally connecting said firSt panel portion and said first pour spout forming panel, said first pour spout forming panel including a depressible starting portion adjacent said first fold line and an outwardly extensible gripping portion spaced from said first fold line, a second pour spout forming panel defined in said second panel portion by a second cut line terminating at each end thereof adjacent a second fold line pivotally connecting said second panel portion and said second pour spout forming panel, said second pour spout forming panel being positioned for alignement with said first pour spout forming panel for outward pivotal movement therewith, at least one portion of said second panel portion adjacent said second cut line being positioned for alignement with said gripping portion providing blocking means for preventing inward movement of said gripping portion and for providing outward extension thereof upon depression of said depressible starting portion toward the interior of the completed carton.

Claim 15
