2 Claims.

This invention relates to dispensing cartons and more particularly to cartons of the type containing rolls of paper such as Wax paper which dispense the paper in web form, which paper may be torn from the dispensed web in pieces of desired lengths against a cutting edge secured to the carton.

Prior to the instant invention, wax paper dispensing cartons have been made of cardboard blanks folded into the shape of a rectangular parallelepiped in which the structure comprises a tray for receiving the roll of wax paper and "a top portion, which top portion includes a front flap.

In some prior boxes the web is dispensed between the front flap which is disposed inwardly of the tray and the front of the tray. As the web is dispensed the tendency is to pull the roll entirely out of the tray causing the roll to fall on the floor which, of course. would be unsanitary, and it is necessary to hold the top in place with one hand while the web is pulled with the other hand. Further, the roll may fall out of the box if the box is dropped inadvertently.

In other prior constructions, the top portion comprises a fold line intermediate the front'and back of the top portion, which fold line extends from one small side of the carton to the other small side and the rear portion of the top back of the fold line is fastened to the small sides or ends of the carton in such a manner that when the top is opened it provides an opening which is smaller than the diameter of the roll to be dispensed. Such prior constructions involve a weakened top and after continued folding of the top the tendency is to tear that portion of the top which is attached to the sides which, when torn, results in a failure of the box to function in the manner desired.

Still another prior construction involves the use of cylindrical bearings secured to the inner faces of the small end walls of the carton o'r tray which bearings extend within the core of the roll to be dispensed. Such cylindrical bearings are difficult to incorporate in a wax paper box dispenser and the resulting construction is expensive to manufacture. Further, in constructions of this type the wax paper roll cannot be loaded into the box after the box is assembled.

It is an object of the instant invention to provide a relatively simple box construction which may be readily manufactured, conveniently used and from which the roll can not be readily -dis-' placed accidental-1y such as when the box is dropped or when it is inverted.

It is another object of the invention to provide a wax paper dispenser which will dispense paper smoothly and conveniently from a roll.

It is a further object of the instant invention-to teach a method of folding a wax paper car-ton from a blank and loading same with a roll of wax paper.

It is still a further object of the instant invention to provide a novel wax paper carton dispenser blank from which the carton may be made by folding same.

Other objects and the nature and advantages of the instant invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a view in perspective of a carton in accordance with the instant invention with the front flap thereof on the outside of the carton and with the piece which covers the finger g-r i-p opening unremoved from the carton;

Fig. 2 is a view similar to Fig. '7 with the top of the carton raised to expose the roll therein and with the piece which covers the finger grip opening-removed;

Fig. 3 is a view partly in front elevation and partly in vertical section with the front flap disposed on the inside of the car-ton behind the web of material to be dispensed;

Fig. 4 is a transverse vertical section taken at right angles to the view shown in Fig. "3; and

Fig. 5 is a plan view of a blank from which the carton-is made.

Referring to the drawings, the blank H), see Fig. 5, comprises a front section II, a bottom sec tion 12, aback section it, a top section [4, and a front flap 15. The sides l6 of the ca'rtonfsee Figs. 1 and 2, are made up of the rectangular tabs 1 which project from the front section H, the trapezoidal tabs l8 which extend from *the bottom section I2, and the rectangular tabs l9 which extend from the back section l3. Extending from the bottom of the rectangular tai'bs ll are the rectangular flaps H which are separated from the rectangular tabs I1 by the fold lines ll". Extending upwardly from the rectangula-r tabs 19 are the spindle bearing portions 20 provided with circular holes 20 as shown in Fig. '5 on'the carton blank ID.

A finger grip opening in the carton may extend into the top section i and front fi'ap'lffi which opening may be temporarily closed by the piece 2| which is held to the top section 14 by a space hetween the perforations as shown, and

the portion of the piece '2! which extends within the flap It may be completely severed there'- from. The cutter edge element 22 may be of metal secured to the top 3| of the front section H.

The score line 23 provides for convenient folding of the front section II and bottom section l2 so that the front section I I and the bottom section 42 may be arranged in planes at right angles to each other. The score line 24 between the bottom section I2 and the back section I3 provides for convenient folding of these sections so that they may be arranged in planes at right angles to each other. The score line 25 between the top section l4 and the back [3 provide a convenient hinge between the top and the back. The score line 26 provides a convenient hinge between the top section M and the front flap IS. The spindle bearing portions 20 are adapted to be laid over on the inside of the tabs 19 in the form of the easy curved section 27, as shown in the upper left-hand portion of Fig. 3. The score lines 28 provide a convenient fold line between the tabs l9 and the back section I 3. The score lines 29 provide a convenient fold line between the trapezoidal tabs l8 and the bottom section l2. The score lines 38 provide a convenient fold line between the rectangular tabs l1 and the front section i I.

In the complete assembly, the tabs IT form the outer lamina of each of the sides N3, the tabs l8 form the intermediate lamina of each of the sides 16, and the tabs i9 form the inner lamina of each of the sides it. The tabs I7, 13 and I9 in the assembly ma be suitably fastened together with adhesive or by the use of staples or the like, and it is obvious that when the tabs l1, l8 and it are laminated as shown in section in Fig. 3, a tray-like structure, as shown in Fig. 2, will result with the top section it formed integral with the back #3 with a hinge line at 25 as shown in Fig. 2. portions 20 which are arranged as shown in section in Fig. 3 have the openings 26' associated with the extreme ends of the core 32 of the wax paper roll 33 in a manner such that the ends of the core 32 are journalled for rotation within the openings 20' of the spindle bearing portions 20. As shown in Fig. 3, the ends of the core 32 extend beyond the ends of the roll of wax paper 33.

The roll of wax paper 33, including the core 32, is adapted to be loaded within the dispensing carton either through the top opening or through the end. When the box is to be loaded through the top, the box is assembled as described and the roll inserted through the top opening into the position shown in Fig. 3, and the ends of the core 32 will automatically slip into the position with respect to the openings 26' in the spindle bearing portions 20 as shown in Fig. 3.

When the box is to be loaded through the end, the blank shown in Fig. is first folded along

score lines

23, 24, 25, and 26 and the flap I5 is then secured to the front section ll either on the inside of the front section H or on the outside by glueing or by the use of a conventional tongue and slit arrangement. The roll 33 is then inserted through one of the open ends or sides. Then the spindle bearing portions 20 are turned over on the inside of the carton to take the position shown in Fig. 3 and the tabs l1, I8, and I9 are folded along

score lines

28, 29 and 30 and the side l6 assembled by lamination as already described above and the rectangular flaps l'! which are folded along line H" to take the position shown in Fig. 3 complete the assembly.

The spindle bearing The user may open the box as shown in Fig. 3, remove the piece 2! and then insert the flap l5 behind the started web as shown in Fig. 4. The web may then be pulled out to the desired length and torn across the cutter edge 22. Thereafter, the web may again be started by inserting a finger through the opening formed by the removal of the piece 2| and pulling a short length of web upwardly so as to expose same. As lengths of web are pulled from the roll, the roll revolves with the exposed ends of the core 32 within the openings 20 of the spindle bearing portions 20 smoothly and the dispensing operation is facilitated without concern regarding the possibility of the roll being pulled entirely out of the box as the spindle bearing portions 20 hold the roll securely within the box while the dispensing operation progresses. Even when the box is inverted with the top [4 open, the roll will not fall out of the box and, accordingly, the user need have no concern about the roll falling on the floor and becoming unsanitary.

It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
