Vending and reclosure device for powder and granular products

Claim 2

A resealable container comprising inner and outer panels disposed in overlapping relation, said inner panel defining a dispensing opening, said outer panel having formed therein a closure flap overlying said dispensing opening, said outer panel having spaced side edges, said closure flap being positioned between said outer panel side edges in spaced relation to said side edges, said closure flap having side edges and ends, said closure flap side edges being defined by zig-zag lines of weakening, one of said ends being defined by a fold line and the other of said ends being separable from said outer panel, whereby said closure flap may be partially separated from and hinged relative to said outer panel to uncover said dispensing opening upon completely rupturing said outer panel along said zig-zag lines of weakening, said zig-zag lines of weakening defining along each side edge of said closure flap a series of projections, and said inner panel having a cut line therein underlying and being generally aligned with each of said zig-zag lines of weakening, said cut lines defining on said inner panel shoulders behind which said closure flap projections are engageable in the resealing of said container.

Claim 3

A resealable container according to claim 1 wherein said outer panel is secured to said inner panel between said zig-zag lines of weakening and said outer panel side edges.

Claim 4

A resealable container according to claim 1 wherein said inner panel and said outer panel are end forming panels of said container.

Claim 5

A resealable container according to claim 1 wherein a central portion of said closure flap has a transverse fold line extending between said closure flap side edges for facilitating depressing of said closure flap side edge projections behind said inner panel shoulders.

Claim 6

A resealable container according to claim 1 wherein said dispensing opening is between said inner panel cut lines.

Claim 7

A resealable container according to claim 1 wherein said inner panel cut lines define an inwardly deflectable panel between said shoulders, the inward deflectability of said inner panel facilitating the engagement of said closure flap side edge projections with said shoulders.

Claim 8

A resealable container according to claim 6 wherein each of said inner panel cut lines has at each end thereof an extension, and said extension at each end of said cut lines being disposed in converging relation.

Claim 9

A resealable container according to claim 6 wherein said container also includes a pair of innermost panels underlying said inner panel, said innermost panels being half panels and having free ends in opposed relation; said innermost panels free ends being notched to define an opening of a size greater than that of said inwardly deflectable panel so as to not interfere with the engagement of said closure flap projections behind said shoulders.

Claim 10

A resealable container according to claim 1 wherein said fold line is interrupted by a projecting tab defined by a cut line in said outer panel, said tab forming means for holding said closure flap in an open position.

Claim 11

A resealable container according to claim 1 wherein said zig-zag lines of weakening extend through an end edge of said outer panel.

Claim 12

A resealable container according to claim 1 wherein said closure flap has a transverse fold line adjacent said closure flap other end, said transverse fold line defining a terminal flap portion, a cut line in an adjacent portion of said closure flap interrupting said transverse fold line and defining an auxiliary locking tab projecting from said terminal flap portion, and said inner panel having an opening therein for receiving said auxiliary locking tab and defining on said inner panel a further shoulder for receiving therebehind said auxiliary locking tab.

Claim 13

A container blank comprising a plurality of panels integrally connected along a plurality of fold lines, said panels including two panels positioned relative to others of said panels for folding into overlapping relation, said two panels being identified as an inner panel and an outer panel, said inner panel defining a dispensing opening, said outer panel having formed therein a closure flap for overlying said dispensing opening, said outer panel having spaced side edges, said closure flap being positioned between said outer panel side edges in spaced relation to said side edges, said closure flap having side edges and ends, said side edges being defined by zig-zag lines of weakening, one of said ends being defined by a fold line and the other of said ends being separable from said outer panel, whereby said closure flap may be partially separated from and hinged relative to said outer panel to uncover said dispensing opening upon completely rupturing said outer panel along said zig-zag lines of weakening, said zig-zag lines of weakening defining along each side edge of said closure flap a series of projections, and inner panel having a cut line therein for underlying and being generally aligned with said zig-zag lines of weakening, said cut lines defining on said inner panel shoulders behind which said closure flap projections are engageable in the resealing of a resultant container.

Claim 14

A container blank comprising a plurality of panels integrally connected along a plurality of fold lines, said panels including two panels positioned relative to others of said panels for folding into overlapping relation, said two panels being identified as an inner panel and an outer panel, said inner panel defining a dispensing opening, said outer panel having formed therein a closure flap for overlying said dispensing opening, said outer panel having spaced side edges, said closure flap being positioned between said outer panel side edges in spaced relation to said side edges, said closure flap having side edges and ends, said side edges being defined by zig-zag lines of weakening, one of said ends being defined by a fold line and the other of said ends being separable from said outer panel, whereby said closure flap may be partially separated from and hinged relative to said outer panel to uncover said dispensing opening upon completely rupturing said outer panel along said zig-zag lines of weakening, said zig-zag lines of weakening defining along each side edge of said closure flap a series of projections, and inner panel having a cut line therein for underlying and being generally aligned with said zig-zag lines of weakening, said cut lines defining on said inner panel shoulders behind which said closure flap projections are engageable in the resealing of a resultant container.
