Abstract

Abstract A carton is provided which may be prepared from an integral blank and which when properly glued together, may be stored in flat folded condition. The folded carton may be quickly erected to form a carton in the form of a polygonal prism having a closed bottom and another end which is readily closable by interlocking a plurality of flaps. A separate tray is provided which is inserted into the carton at an intermediate position. The side walls of the carton are suitably cut and scored to provide tabs which, upon erection of the carton, are punched inwardly to provide vertically oriented supports for the tray.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 90 words
A carton in the form of a polygonal prism comprising: a. a plurality of side panels, b. a top closure, c. a bottom closure, d. a tray positioned intermediate said top closure and said bottom closure, and e. support means associated with said side panels engaging and supporting said tray, wherein some of said side panels are appropriately cut and formed to provide a plurality of planar tabs extending inwardly and in a vertical plane with respect to said carton, said tabs engaging and supporting said tray at their edges.
Claim 2
Dependent Claim 90 words
A carton in the form of a polygonal prism comprising: a. a plurality of side panels, b. a top closure, c. a bottom closure, d. a tray positioned intermediate said top closure and said bottom closure, and e. support means associated with said side panels engaging and supporting said tray, wherein some of said side panels are appropriately cut and formed to provide a plurality of planar tabs extending inwardly and in a vertical plane with respect to said carton, said tabs engaging and supporting said tray at their edges.
Claim 3
Dependent Claim 11 words
A carton according to claim 1, having at least six sides.
Claim 4
Dependent Claim 31 words
a second supporting flap hingedly connected to the end of an adjacent one of said side panels comprising a supporting flap member and a glue flap member hingedly connected thereto, and
Claim 5
Dependent Claim 31 words
a second supporting flap hingedly connected to the end of an adjacent one of said side panels comprising a supporting flap member and a glue flap member hingedly connected thereto, and
Claim 6
Dependent Claim 122 words
said glue flap being adhesively affixed to a medial portion of said first supporting flap and said first supporting flap having an overhanging portion extending beyond the hinge line between said supporting member and said glue member, the arrangement being such that each supporting flap assembly folds inwardly at the hinge line between said hinge member and said flap member permitting said bottom closure to be folded flat with the remainder of said carton for storage, and whereby when said carton is erected and said bottom closure is placed in planar position said overhang abuts the upper surface of said supporting flap member, thereby restraining said flap assembly from bending outwardly of said carton, and providing positive support for said polygonal flap.
Claim 7
Dependent Claim 122 words
said glue flap being adhesively affixed to a medial portion of said first supporting flap and said first supporting flap having an overhanging portion extending beyond the hinge line between said supporting member and said glue member, the arrangement being such that each supporting flap assembly folds inwardly at the hinge line between said hinge member and said flap member permitting said bottom closure to be folded flat with the remainder of said carton for storage, and whereby when said carton is erected and said bottom closure is placed in planar position said overhang abuts the upper surface of said supporting flap member, thereby restraining said flap assembly from bending outwardly of said carton, and providing positive support for said polygonal flap.
Claim 8
Dependent Claim 9 words
A carton according to claim 1, which is hexagonal.
Claim 9
Dependent Claim 12 words
A carton according to claim 1, wherein said tabs have arcuate ends.
Claim 10
Dependent Claim 23 words
A carton according to claim 1, wherein said tray is provided with vertically extending flaps frictionally engaging the side panels of said carton.
Claim 11
Dependent Claim 155 words
A carton according to claim 1, wherein said top closure comprises a plurality of closure flaps hingedly connected to the ends of said side panels and interconnected laterally to form a closed loop, each of said closure flaps comprising a flap member and a triangular web hingedly connected thereto, said flap members and said webs each having an edge perpendicular to the hinge line connecting said flap members and said side panels and another edge oblique thereto, the oblique edges of said flap members and said webs being hingedly connected together, and the perpendicular edges of said flap members and triangular webs being connected to the perpendicular edges of webs and flap members, respectively, of adjacent closure flaps, the oblique edges of said flap members passing through the center of said closure when said flap members are in closed condition, said flap members terminating in an arcuate tab extending beyond the center of said closure.
Claim 12
Dependent Claim 67 words
A carton according to claim 6, wherein said bottom closure comprises: a. a polygonal bottom panel being connected at one edge to the end of one of said side panels and having substantially the same dimensions and shape as the cross-section of said carton, and b. two supporting flap assemblies disposed one on each side of and below said polygonal bottom panel, each of said assemblies comprising:
Claim 13
Dependent Claim 38 words
A carton according to claim 1, wherein a pair of apertures are provided in the side panels, a handle the ends of which pass through said apertures, and means anchoring the ends of said handle within said carton.
