12 claims.

This invention relates to a carton for retaining a roll of sheet material and dispensing lengths therefrom, said carton being formed from a single integral blank and provided with a cutting edge of novel construction formed from the blank itself for cutting desired lengths of sheet material. More specifically, this invention relates to a dispensing carton for retaining a roll of waxed paper 'andother types of frangible sheet materials from which suitable lengths of the sheet material may be dispensed from the carton.

Hitherto it has been the common practice to provide dispensing cartons of this typewith metal cutting blades afiixed to a free wall portion of the carton to provide a cutting edge for cutting lengths of sheet material from the roll retained in the carton. The manufacture of such cartons provided with metal cutting blades entailed considerable expense not only on account of the cost 4 of the material involved, but also on account of the additional operations required in suitably aihxing the metal cutting blade to the carton. Furthermore, the use of metal cutting blades was a source of possible injury to the user of the carton. Such cartons also could not be disposed of or destroyed readily when empty on account of the metal cutting blade.

According to the present invention, the aforementioned difiiculties and disadvantages have been fully overcome. A carton is providedwhich is formed from a single integral blank of cardboard and the like which is suitably out and scored to form a receptacle for receiving and retaining a roll of sheet material, one of the walls thereof being provided with a cutting edge for sheet materials by providing the wall portion with a continuous cut score extending the full. length of the wall portion, the wall portion being folded back along the cut score to position an exposed cut edge of the folded portion in oifset relation to the congenetic cut edge of the wall portion, the folded-back portion being adhered to the con tacted inner face of the wall portion.

Otherfurther details of th invention will be apparent from the following specification and appended drawings.

Referring to the drawings, Figure Lshows a carton formed from an integral single blank shown in Figure 2 for retaining a roll of sheet material and for dispensing lengths A oi the sheet material by cutting same against a cutting edge provided in the carton. The blank may be formed of any suitable material, such as cardboard and the like, suitably cut and scared to provide a receptacle portion for retaining the roll of Figure 1, partly in i 90 of sheet material. formed by folding the blank along score lines I and 2 to form a front'panei IS, a bottom panel 15 and a rear panel it. These panels are provided with hinged end flaps indicated by numerals then folded over the ends of the receptacle and adhered thereto in the position shown in Figure 1.

A cover is hingedly connected to the top panel l3 along a hinge line 4. The hinge line may be of any suitable construction, but it is preferred to use a hinge line having alternately arranged semi-circular cuts and creased score lines as disclosed in Broeren-Patent No. 2,303,253 November 24, 1942. The cover is formed of a closure panel l2 having end flaps l9. The closure panel normally extends in the same plane as the fixed top panel l3 and can be hinged upwardly in the position shown in Figure 4, whereby access to the receptacle may be had if necessary for grasping the end A of the web of sheet material for dispensing purposes. A cutting panel In is hingedly connected to the closure panel along scoreline 5. The cutting panel is provided with end flaps integrally hinged thereto. These end flaps are indicated by numerals l1 and i8 and are adapted to. be folded back on themselves The receptacle portion is assasas line 40 is positioned in offset relation to the hinge score lines 30 provided in the end flaps of the cutting panel l as clearly shown in Figures readily cut by a pulling action on the end of" 8 and 9. When the panel portion 9 is folded back so as to hinge along the score lines so, the cut edge of panel 8 will be offset in relation to the panel in asshown in Figure 8. The cut score line is preferably formed by applying the cutting knife to the outer face of the blank and pushing the fibers toward the inner face of the blank, as shown in Figure 6, whereby a very sharp cutting edge 60 is formed in each of the congenetically cut edges in the cutting panel I 0. As shown in Figure 8, the exposed edge of the panel portion ii has a sharp knifeedge contour so that the sheet material can be the web against the cutting edge in the manner shown in Figure 1. The panel portion 9 also serves as a reenforcing extension when it is folded back and adhered to the panel in and serves to stiffen the full length of the cutting panel so as to resist bending and distortion when the carton is used for dispensing'purposes. As shown in Figure 3, the cutting panel I0 is adapted to overlap the adjoining front wall l6 of the receptacle and the sheet material is passed for withdrawal from the roll between the front panel l6 and the overlapping cutting panel Ill.

We have found it advantageous to coat or 1m pregnate the exposed cutting edge with an indurating material, such as molten sulphur, synthetic resins, waxes, lacquers, and the like, for stiffening the fiber material of the blank at and adjacent the cutting edge, whereby a rigid cutting edge is provided which will not soften in humid weather or become dull in use.

along score line 30 as shown in Figures 2, '7 and 8, and are adhered to the overlapped flap portions. The cutting panel is provided with a cut score line 40 which extends the full length of the panel IG and is intersected at the ends thereof by short slits 4i extending at right angles thereto and terminating at the score lines 30.

In forming the cutting edge for the web of sheet material, the cutting panel in is folded ,back on itself on the score lines 35 shown in enlarged view in Figure 7 to assume the position indicated in Figure 8. The cut edge 60 of the folded back portion will then be positioned in offset relation to the congenetic cut edge of panel I0.

The folded back portion .9, together with the hinged end flap portions I! are glued or secured in any suitable manner to the overlapped inner face of the cutting panel 10. The end flap portions I1 and I8 are cut in such contour as to coincide throughout their area when they are superposed. These superposed end flaps l1 and i8 are then folded over and adhered to the end flaps ill by an adhesive 19. as shown in Figure 5, to form side ends for the cover in the relation shown in Figure 1. It will be noted that these side ends have a 3-ply thickness thus giving very rigid ends. The broad features of the end flap construction are covered in Sullivan et a1. Patent No. 2,314,849, March 23, 1943. When the carton is produced by automatic machinery it is preferred to fold the panel portion 9 and adhere it to the overlapped body of the blank prior to feeding the blanks to the automatic carton making machine.

An important feature of the present invention relates to the cutting edge which is formed from the blank shown in Figure 2. The cut score It is to be understood that the cutting edge construction, previously described, is not limited merous changes and modifications may also be made embodying the principle of this cutting edge construction. For example, the relative positions of the score lines 30 and cut score line All may be varied to provide any desired amount of offset for the cutting edge in relation to the shear panel. Also if desired, the score lines 30 and cut score line 40 may be reversed from the position shown in Figure 2 so that when panel portion 9 is folded back, the exposed cut edge of panel 10 will be offset in relation to panel 9, the free edge thereof providing the cutting edge.

Figures 10 to 15 show another type of dispensing carton construction formed also from a single integral blank. The blank is suitably cut and scored to provide a front panel 50, a bottom panel 5|, a rear panel 52, a closure panel 53 and an extension panel 54. End flaps 55, 56 and 51 are hingedly connected to the front, bottom and rear panels, respectively. Front panel 50 is provided with a cut score line 40 extending the full length of the panel 50. The cut score line 40 is formed in the manner previously described in connection with the carton construction shown the score line so to the cut score line 40, the cut edge 80 of panel 10 will be ofiset in relation to the cut edge of the front wall 50, thereby providing a cutting edge for the end A of the web of sheet material.

In forming the carton from the blank as shown in Figure 11, the front and rear panels are folded up at right angles to the bottom panel and their respective end flaps are superposed and glued together, preferably with the end flaps 56 positioned intermediate the end flaps '1 and 55. The portions 58 of flaps 51 are adapted to be folded over the open end of the receptacle so formed. The cover 53 may then be folded over in the position shown in Figure 13 and the extension flap 54 is then inserted within the receptacle. The web of sheet material is adapted to be withdrawn from the carton between the front wall 50 and the inserted flap extension 54; The cutting edge may also be indurated in the manner l.
