2 Claims.

This invention relates to packages for sheets of carbon paper.

The invention relates particularly to packages for sheets of carbon paper of odd sizes although certain features of the invention may be embodied in constructions in which may be packed carbon sheets of standard size as well as odd sized sheets.

A large proportion of the carbon sheets sold by manufacturers of carbon paper often consists of odd sized sheets. It has been a diicult problem, in plants in which carbon paper is manufactured, to pack odd sizes of such paper for shipment economically. On account of the number of sizes of the carbon sheets, when they are packed in boxes, it is necessary to maintain a large number of sizes of boxes in stock, and even then orders will often be received for a size for which there are no boxes. The paper then either is packed in non-tting boxes or the shipment is held until boxes are secured to fit the same. The maintaining of a large number of boxes of different sizes in stock involves considerable expense.

One object of the present invention is to 'improve the construction of packages for sheets of carbon paper and to provide a novel package in which may be packed alternatively a plurality of diierent sizes of sheets.

Another object of the invention is to produce Va package for carbon paper in which a relatively large number of different sizes of sheets may be eiciently packed in stacked arrangement.

Another object of the invention is to produce a package for sheets of carbon paper of odd sizes in which the packages are of standard sizeso that they may be packed in standard size wooden boxes or other containers employed-for shipping wholesale quantities of standard size sheets.

With the above and other objects in view, the invention consists in a package involving the novel and improved features hereinafter described and particularly pointed out in the claims, the advantages of which will be readily understood and appreciated by those skilled in the art.

The invention Will be 'clearly Vunderstood from the accompanying drawings illustrating the Yinvention in its preferred form and the yfollowing detailed description of the construction therein shown.

VIn the drawings:

Fig. 9 is a view similar to Figs. 3 and 6 except that a sheaf of carbon paper of a still vdifferent size is inserted in the container, l

Fig. 10 is a sectional view taken substantially on the line lli-I ll of Fig. 9,'and

Fig. ll is a plan view ofthe container with'the sheaf of carbon paper shown in Fig. 9 Ainserted therein and with the flaps of the inner `and outer folders folded over upon said sheaf.

in the form of the invention illustrated in the drawings, the package or container comprises an outer folder indicated at 2 preferably made of relatively heavy paper or relatively thin, light, iiexible cardboard, which will be referred to hereinafter, generally, as paper board, and an inner folder indicated at 24 made Vof similar material. The folder 2 comprises a central .panel indicated at 6, of rectangular outline, from which extend two lateral `naps indicated at 8 and two end yflaps indicated at i li. Toenable theV flaps readily to be folded over into positions opposite the central panel, the folder is provided With .two sets of `weakened lines indicated respectively at I2, .12a

and Irl, ida, .one set between the `body of each of the `flaps 8 and the central panel 6,.and withftwo than thatfof the `thickness ofthe 'shear lof carbon sheets containing the maximum number of sheets which will be shipped inthe package. One of the rflaps i8 is provided :with a rtongue 21) arrangedvto The nap 3u of the folder 24 is provided with pairs of weakened lines 34 and 34a, 36 and 36a andV 38 and 38a to enable this ap to be readily folded inwardly along these lines. The lines 34 and'34arespectively, are located slightly inside the lines I6 and I6a of the corresponding flap I0 ofthe folder 2. The flap 32 of the folder' 2,4 is formed with pairs of weakened lines 40 and 48a, 42 and 42a and 44 and 44a to enable this flap readily toy bejfolded inwardly along these lines. Thev lines 48 and 40d are located respectively slightly inside the lines I8 and I8a of the adjacent flap I8 of the folder 2. The flap 26 is provided with pairs of weakened lines 46 and 46a, 48 and 48a, and 58 and 50a to enable this flap readily to be folded inwardly along these lines. The lines 46 and 46a espectively, are located slightly inside the corresponding lines I2 and I2a of the corresponding flap 8 of the folder 2. The flap 28 of thev folder 24 is formed with pairs of weakened lines 52 and 52a, and 54 and 54a to enable this flap readily to be folded inwardly along these lines. The lines 52 and 52a respectively, are located slightly inside the respective lines I4 and I 4a of the corresponding flap 28 of the folder 2.

The weakened lines of the two folders are formed by scoring or perforating the material of the folders or in any other convenient manner. With the above construction a large number of sizes of carbon sheets may be readily packed for shipment. Figs. 3, 4 and 5 show a sheaf or pack 56 of carbon sheets placed in the package. This sheaf contains sheets of the largest size which the package is arranged to accommodate. These sheets may be of a standard size. These sheets are of a size slightly less than that of the central panel 6 of the folder 2. In packing such a sheaf, with the flaps all unfolded as shown in Fig. 1, the sheaf is placed upon the inside folder 24 with the edges' of the sheaf just inside the cuter lines of the panel 6 of the outer folder 2 and the flaps 38, 32, 26 and 28 of the inner folder are folded over inwardly on the pack along the lines 34, 34a, 40, 40a, 46, 46a, and 52, 52a as shown in Figs. 3 and 4. The flaps 8 and I0 are then folded over inwardly on the pack along the lines I6, I6a, I8, I8a, I2, I2a and I4, I4a as shown in `Fig. 5, with the flaps I8 on the inside and the itongue 2!) is inserted in the slit 22 to lock the flaps of the outer envelope in place.

Figs. 6, 'l and 8 show the manner in which a sheaf 58 of sheets of carbon of another size is packed in the package. The sheets of this pack are .of substantially a. length to fit between the lines 38a, 42a and of a width to fit between the lines 48a and 54a of the inner envelope. In packing this sheaf, the sheaf is placed upon the inner folder just inside the lines 36a, 42a, 48a and 54a and the flaps 30, 32, 26 and 28 are foldedover -inwardly upon the same along the lines 36, 36a,

42, 42a, 48, 48a and 54, 54a into substantially the positions shown in Fig'. 6. The aps I8 and 8 of the outer folder are then folded over inwardly -along the lines I6, Ilia, I8, I8a, I2, I2a and I4,

14a upon the inner folder with the aps I0 on the inside as shown in Fig. 7, and the tongue is inserted in the slit 22 to lock the flaps of the outer folder in position.

Figs. 9, 10 and 11 show the manner in which a sheaf 60 of sheets of carbon paper of still another size is packed in the package. The sheets of this sheaf are of substantially a length to t between the lines 33a and 42a of the inner folder and of a width to t between the lines 46a and 54a of said folder. In packing the sheaf 6D, said sheaf is placed on the inner folder 24 with its edges just inside the lines 38a, 42a, 46a and 54a of said folder and the aps 30, 28, 32 and 28 are folded over inwardly upon the sheaf along the lines 38, 38a, 42, 42a, 46, 46a and 54, 54a respectively, into the positions shown in Figs. 9 and 10. The flaps Y I0 and 8 of the outer folder are then folded over .ferred form, what is claimed is:

inwardly upon the inner folder and the sheaf contained therein along the lines I6, l6a, I8, I8a,

`I2,'. I2a, and I4, I4a into the position shown in Fig. ll with the flaps I8 on the inside Vand the tongue 28 is inserted in the slot 22 to lock the .flaps in position.

The spacing between the weakened lines of each pair of the inner folder is for the purpose of accommodating the thickness of the sheaf of sheets packed in the same. The portion of each flap between said lines ts along the edges of the sheets of a sheaf in the manner shown clearly in Figs. 4, 8 and 10.

The flaps of the inner folder 24 may be folded along different combinations of the weakened lines to accommodate packs of sheaves of sheets having a number of different lengths and a number of different widths. The construction shown is designed for the packing of sheaves of forty two different sizes. The weakened lines on the folders may, of course, be varied in positions as found desirable for the packing of sheaves of any sizes and there may be as many of these weakened lines as desired.

With the above construction, not only may a pack of sheets of the largest size which the outer folder 2 is constructed to accommodate be packed but the smaller sizes also may be quickly and easily packed in the package and are snugly held therein without the use of additional packing material. Thus in the cases shown, the sheaves .58 and 68 of carbon sheets are firmly and seinvention and having illustrated and described a construction embodying the invention in its pre- 1. A package for sheets of carbon paper comprising an outside folder of relatively thin,''ex ible paper board having a substantially rectangular central panel, a plurality of flaps extending from said panel, each having weakened transverse 'substantially parallel fold lines and ar- .ranged -to begfolded inwardly' along said lines to"- Ward said panel to form'side walls of an outer casing and an enclosing cover opposite the panel, an inside folder of similar material having a substantially rectangular central panel of less length and Width than the rst panel attached directly to the central panel of the outside folder anda plurality of aps extending from said central panel and respectively having substantially the same width throughout as the corresponding dimensions of the latter panel, said flaps extending outwardly diierent distances from the latter panel and having transverse fold lines along which the flaps are arranged to be folded inward,- ly toward said panel, said flaps being of sufficient length to extend beyond the margins of said panel of the outside folder and one or more of said naps of the inside folder` having weakened fold lines located at different distances from the corresponding center line of the folder to enable the ilaps to be folded at different points for different sizes of carbon sheets placed therein.
