Abstract
Cardboard container for dispensing a roll of sheet material consisting of a box with a slotted top through which is dispensed material fed from a supply roll contained in the box. The container is constructed of a single sheet of paperboard folded and slotted so as to provide a centering device for the supply roll when the paperboard is folded to form a box.
Claims5
A cardboard container for dispensing sheet material from a wound supply roll thereof stored in the container, said container being formed of a single piece of cardboard folded into a rectangular box having sides and ends, one of said sides having a slot through which the free end of said sheet material projects and formed therein by positioning flaps resiliently folded into said container, said flaps forming means to maintain said supply roll in place within the container as sheet material is dispensed therefrom and said supply roll becomes smaller, said ends being provided with bifurcated tuck flaps, said bifurcated flaps passing on each side of said positioning flaps folded into said container to constrain the positioning flaps within said container.
A container for dispensing sheet material wound in a roll in the container, the container comprising a plurality of walls interconnected to one another and forming an enclosure in which a cylindrical roll of sheet material is both longitudinally and diametrally constrained loosely, one of said walls having a slot formed therein and extending longitudinally of said roll of sheet material for accommodating and making accessible externally of the container a leading unwound portion of said sheet material, and resilient means connected to at least one of said walls for continually pressing said roll of sheet material against another of said walls and thereby constraining said roll of sheet material in a generally stable angular disposition against inadvertant unwinding substantially independently of any diametral size reduction said roll may undergo, said resilient means being connected to said one wall in which said slot is formed, said resilient means comprising at least a first flap secured to one longitudinal edge of said slot and extending substantially the full longitudinal length of said slot, said first flap having a width transversely of said edge of said slot of sufficient span to contact said roll of sheet material and urge it against at least a wall of said container opposite said one wall in which is formed said slot, and first scored transition means interconnecting said first flap to said one longitudinal edge of said slot for urging said flap resiliently into continual contact with said roll, said resilient means further comprising a second flap similar in size and configuration to said first flap and secured to the opposite longitudinal edge of said slot, and second scored transition means interconnecting said second flap to said opposite longitudinal edge of said slot for urging said second flap resiliently into continual contact with said roll, said first and second flaps being each divided into two portions interconnected to one another through the intermediary of respective additional scored transition means, and including bifurcated means at each longitudinal end of said slot for constraining respective longitudinal end portions of said flaps inwardly of said container.
