14 Claims.

This invention relates to boxes particularly adapted for holding rolls of wrapping paper in such a manner that any desired length of the paper may be drawn out as required and cut off against a tearing edge formed on or carried by the box, and my object is to devise a simple and efficient box for this purpose which will be cheap .to produce, convenient and eflicient in operation and which may be stored in knock-down condition.

I attain myobject by means of a construction which may be briefly described as follows. The box comprises an open topped body portion, and a cover hinged to the body portion and provided with a depending front and ends. The parts are preferably integral and formed from a folded blank.

A special feature of the cover is that its front is formed-of a part integral with the top and the ends, the inner part of the front being formed with a secondary flap adapted to lie against the under surface of the top.

Another object is the provision of an inexpensive cardboard container carrying a paper roll from which paper is withdrawn through the passageway formed between the front of the cover and the front of the lower portion of the container. The front wall of the cover is preferably folded inwardly upon itself providing an upwardly angularly extending primary flap which yieldingly urges the paper Web against the front wall of the lower portion of the container and acts as a brake upon the movement of the paper web while permitting the withdrawal thereof. The folded edge provides a hard smooth reinforced cutting edge against which the paper may be 'severed. This infolded primary flap is tensioned upon closure of the cover and, upon release of the cover, it tends to assist in lifting the cover to expose the end of the paper web so that it may be readily grasped for further withdrawal.

A special feature of the box is that the ends of the front and back are provided with interlocking flaps and that these flaps are embraced by the parts of end members folded on themselves and preferably provided with flaps adapted to lie against the bottom of the box.

The invention is hereinafter more fully de scribed, and is illustrated in the accompanying drawing in which Figure 1 is a cross section of. the container constructed in accordance with my invention with 55 the cover in closed position,

folded on itself to embrace flaps integral with.

the cover partly Figure 4 a perspective detail showing more particularly one corner of the cover partly unfolded;

Figure 5 a perspective view of part of the container showing more particularly one end with the parts partly unfolded, and

Figure 6 a longitudinal section partly broken away.

In the drawing like numerals of reference indicate corresponding parts in the different figures.

Referring to the drawing, it will be seen that the container comprises two main parts, an open. top box and a cover, the one hingedly connected to the other at the top rear edge of the box. Preferably these two parts are integral, being formed from a cardboard blank which will be scored along the line 1 to facilitate bending at that point.

The open top box comprises a bottom 2, front and back walls 3 and 4 integral with the bottom, end flaps 5 integral with the front and back walls and-ends 6 integral with the bottom and folded on themselvesto embrace the end flaps and thus stifien the box ends, and provide smooth unbroken outside surface for printing. The end flaps, as will be seen particularly on reference to Figs. 5 and 6, are interlocked in a known manner to hold the front and back walls in the set up position. Preferably each end 6 has a flap 7 formed on its free edge adapted to lie on the bottom of the box. These flapssupport the ends of the roll of paper and lessen the frictional resistance to the turning of the roll as compared with contact for its full length on the bottom of the box.

The cover comprises the top 8, the ends 9, preferably triangular and integral with the top, and the front 10 integral with the front edge of the top. This front is folded on itself forming a primary flap adapted to embrace the end flaps 11 which are integral with the ends 9, while the front as a whole is held rigidly positioned by the ends 9. A secondary flap 12 is formed on the free edgeof the primary flap or the inner part of the double front, which secondary flap is adapted to lie against the under surface of the top of the cover as shown in Figure 1. The fold of this double front forms a stiff reinforced tearing edge which makes it unnecessary to use metal to form the tearing edge, This fold forms a smooth hard cutting edge superior to the raw edge of a single thickness of cardboard. While the flap 12 might be secured to the under surface of the top 8 I prefer. to leave it free, as shown the springinass of the folded front to hold the portion of a roll of paper which is being drawn out against the free edge of the front of the box, thus tending to prevent its passing back into the box. Another advantage in leaving the double front free is that the lid will retain aslightly raised position when desired to give access to the free end of the web drawn off from the roll. Within the lower portion of the container is disposed for unwinding a roll of paper as shown in Figures 1 and 2.

The element 10 as shownin Fig. 1 is folded upon itself and due to its inherent resilience, bears upon the front face of wall 3, exerting a force normal to that wall which may be assumed to act at a point midway of the depending dimension of the element 10. The force thus exerted gives rise to an equal and opposite reaction by the wall 3 upon element 10. Treating the cover portion of the box as a free body and taking a summation of moments about the hinge axis at 1, the reaction force of the wall 3 upon the element 10 produces a clockwise moment about axis 1 equivalent to the product of the forceabove in pounds and half the depth of the depending element 10 in inches. The opposing moments are due to the friction between element 10 and wall 3, and the weight of the cover multiplied by their respective moment arms. The factors of force due to resilience, the coefiicient of friction between the surfaces, weight and the length of the moment arms, are so correlated as to give a resultant clockwise moment which will effectively raise the cover.

From the above description it will be seen that I have devised a container which will satisfactorily attain the objects of my invention as set out in the preamble of this specification.
