Roll holding carton

In a shipping and storage container for rolls of sheet material of uniform width each convoluted about a hollow center core with the opposite side edges of the material respectively disposed flush with the opposite ends of said core in spaced parallel planes extending normal to the axis of the roll, in combination,

• a. an open-ended box structure having vertically extending right-angularly related side walls respectively provided with integral oppositely projecting hinged closure flaps, said closure flaps being inwardly folded relative to their associated side walls to provide at each of the opposite ends of said box structure overlapping closure flaps extending normal to the side walls of the box structure thereby providing the latter with double-ply top and bottom closure walls,
• b. a post member centrally disposed in said box structure and extending vertically between said closed top and bottom walls thereof and projecting through the hollow center core of said rolls,
• c. means interlocking each of the opposite ends of said post member in fixedly secured position between said overlapping pairs of box closure flaps, and
• d. at least one centrally apertured rigid flat-surfaced member underlying and flat-wise supporting the full circle of convolutions of one of said rolls of convoluted material and at least a portion of the center core thereof thereby maintaining intact the integrity of the roll against telescoping or other distortion of its convolutions, said rigid member being of an overall dimension large enough so as to prevent its radial displacement within said enclosure structure and being of an external perimetral outline sufficiently different from that of the enclosing side walls as to provide at least two diametrically opposed spaces between the perimetral edges of said rigid member and the enclosing side walls of said structure through which one may grasp the underside of said rigid member for axial movement of the roll carried by said rigid member onto or from said post.
