a "corporation of Delaware Application October 6, 1932, 'Serial No. 636,481 Renewed October 16, 1936- 14 Claims.

My invention relates to cartons for packaging, shipping;jstoraging and vending articles of various kinds, such, for example, as chinaware dishes and cups, bottles and the like.

In general, my invention has for an object the provision of a carton adapted to contain a numberof dishes, plates, bottles or other articles in a single unit adapted for sale as such to the consumer, and by means of which the amount of loose packing, such as excelsior or the like, required for the packing of fragile articles of the class described, may be materially reduced or eliminated.

An object of my invention is 'to provide a carton formed from a single continuous sheet of material, adapted to-contain a plurality of articles for shipment, storage or sale as a single unit,and having self-formed partitions adapted to separate said articles, which partitions divide the carton into a plurality of recesses each adapted to receive and retain one of said articles and shaped in accordance therewith.

A further object of my invention is to provide a carton for the purpose set forth above which is provided with exterior walls of double thickness over a sufficient portion-of the carton to provide mechanical strength sumcient to prevent damage or injury to the carton and its contents under conditions of shipment, handling and storage.

A further object of my invention is to provide a blank for forming a carton of the character and for the purpose hereinabove set forth, which is of relatively simple shape or outline and is adapted to be cut from a single continuous sheet of material with a minimum of waste.

My invention has for further object such additional advantages and improvements in construction and detail'as may hereinafter be found to obtain.

In the drawings accompanying: and forming a part of this specification I have illustrated various forms in which'my inventionmay be embodied. In these drawings,

Fig. l is a plan view of a blank for forming a carton in accordance with my invention;

Fig. 2 is a perspective view of a carton formed from the blank illustrated in Fig. 1, said carton being shown in a partly closed condition;

Fig. 3 is a perspective view of the carton shown in Fig. 2, in a completely closed condition;

Fig. 4 is a plan view .of a modified blank;

Fig. 5 is a perspective view of a carton formed from the blank shown in Fig. 4, said carton being shown in. a partly closed condition; and- Fig.6 is a perspective view of the carton, shown in Fig; 5,-ina completely closed condition.

Similar reference numerals designate the same or similar parts in the several views of the drawings. 5

Referring'now to the drawings and more particularly Figs. 1, 2 and 3 thereof, it will be seen that I provide. a blank having a central panel I which is adapted'to constitute the base or bottom of the carton'when formed. The central panel I is of rectangular'shape and is defined by score lines 2, 3, 4 and 5.

Adjoining the panel I along the score lines 2 and4 I provide side panels 6 and 1 respectively.

I The sides of the panel 6 which are at right angles to the score line 2 are defined by score lines 8 and-9 which'are substantially in alignment with and form extensions of the score lines 3 and 5 respectively. Adjoining the side panel 6 along the score lines. 8 and 9 I provide side extension panels In and II respectively which are in turn adjoined along score lines l2 and I3 to end flaps I4 and 15 respectively." The end flaps l4 and I5 are provided with notches I6 and I! adapted for mutual engagement and interlocking when the blank is bent to form a carton as shown in Figs. 2 and 3.

The sides of the panel I at right angles to the score'line 4 are'defined by score lines and 2| which are substantially in alignment with and form extensions to the score lines 3 and 5 respectively. Adjoining the side panel 1 along score'lines 20 and 2| I provide relatively narrow spacing panels 22 and 23 which are in turn adjoined along score lines 24 and 25 by partitioning panels 26 and 21. The panels 26 and Zl'are in turn adjoined along score lines 28 and 29 by spacing, panels 30 and 3|, similar to the panels I 22 and 2 3,'respecti'vely. 40

Adjoining the central panel l along the score lines 3 and 5, I provide exterior side panels 32 and 33, respectively, which are in turn adjoined along score lines 34and 35 by cover flaps 36 and 31 having notches 38 and 39, respectively, which & are adapted to mutually engage and interlock when'the blank is bent to form a carton as shown in Fig. 3.

Extending outwardly from the four corners of the central panel l, I provide straight cuts 40 and. 4.4. which are in alignment with and form extensions of the'score line 2, and also cuts 42 and 43 which formextensions of the score line 4. The cut 40 and 42 separate the panel 32 from the panels l0 and 26 respectively, while the cuts 4| and 43 separate the panel 33 from the panels II and 21 respectively.

In this instance, in which the partitions formed by the panels 26 and 21 are intended to traverse the carton in planes parallel to the sides 32 and 33 when the latter have been bent at right angles to the central panel I, the following relationship should exist between various dimensions of the several panels:

The dimension a of the panels 32 and 33 should equal the dimension D of the panels Gand I and the panels adjoining the latter along the score lines 8, 9, 20 and 2|. The dimension 0 of panels 26 and 21 as well as the dimension d of panels In and II should equal the dimension e of the central panel I. The dimension 1 of the spacing panels 22, 23, 36 and 3% should be equal to about one-third of the dimension 9 of the central panel I.

It should be borne in mind, however, that in planning these dimensions and in cutting and scoring the blank, allowance must be made for the thickness of the material from which the blank is formed. Thus in practice, especially when material of considerable thickness is employed, as will be evident from inspection of Fig. 2, the actual dimension 0 of the panels 23 and 2'5 will be slightly smaller than the dimension d of panels Ill and II due to the fact that the panels 26 and 21 are intended to form partition members lying within an enclosure formed in part by the panels Ill and II.

It will further be obvious that, especially when material of considerable thickness is employed, such score lines as have been stated hereinabove are substantially in aligmnent with each other or form extensions one of the other may actually be slightly ofiset at the junctions thereof in order to allow for proper folding of the panels and proper formation of the enclosure. Thus Fig. 1 shows a slight oii'set between the score lines 3 and 20, which offset is provided in order to permit the panels 22, 23 and 30 to be folded within the enclosure formed by the panels 5, III, II, I4 and I5.

In forming the carton from the blank shown in Fig. 1, right angle bends are first made along the score lines 23, 2I, 2t, 25, 28 and 29 in such manner as to bring the spacing panels 22 and 23 against the adjacent surfaces of the panel I, with the spacing panels 3|] and 3! parallel to the panels 22 and 23 and extending outwardly therefrom. A right angle bend is then made along the score line d, which brings the partitions 26 and 21, as well as the spacing panels 22, 23, 3t and 3|, into the position in which they are shown in Fig. 2.

A right angle bend is then made along the score line 2, bringing the side panel 6 into engagement with the panels 39 and 3 I, and further bends are made along the score lines 8, 9, I2 and I3 to bring the panels II], H, H! and I5 around the structure formed by the panels "I, 22, 23, 26, 21, 30 and 3|. When the panels I4 and I5 have been carried around the panel I they are mutually interlocked by means of the notches I6 and II, the carton being at this point virtually in the condition in which it is shown in Fig. 2.

It will be noted from extension of Fig. 2 that a partial enclosure has now been erected upon the central panel I as a base, which enclosure is divided into three compartments by means of the partitions 26 and 21 and their adjacent spacing panels, and which is open at the top, for insertion of articles therein. The carton which I have specifically illustrated in the drawings is of such proportions as to be well suited for the purpose of packaging three flat articles, such as plates or saucers and it may be observed at this point that the dimensions b, e and f indicated on Fig. 1 should correspond to the principal exterior dimensions of each of the articles intended to be packaged in the carton.

It is of course highly desirable that the dishes or other articles, whether wrapped or not, should t into the compartments formed by the partitions 26 and 2'! and the panels II) and II with sufilcient tightness to hold them securely.

In order to complete the enclosure, right angle bends are made along the score lines 3, 5, 34 and 35, bringing the panels 32 and 33 face to face with the panels II) and I I respectively, and bring ing the covered flaps 36 and 31 into position across the hitherto open end of the enclosure, as

is illustrated in Fig. 3. By means of the notches 38 and 39 the covered flaps 36 and 31 are interlocked and the enclosure of the carton is thereby made complete.

The carton thus formed needs, for most purposes at least, no additional sealing or wrapping. The articles packaged within the same are securely held and separated from each other, thus reducing breakage or injury to a minimum. The latter property is also greatly enhanced by the fact that by far the greater portion of the carton is comprised of Walls of more than one thickness. Thus panels IE] and 32 cooperate to provide a side wall of a thickness double that of the blank from which the carton is made.

In the blank and carton shown in Figs. 1, 2 and 3, the panels 25 and 21 are adapted to form partitions running lengthwise of the central or base panel I, that is to say, parallel to the outer side panels 32 and 33 when the carton is completed. This form is especially suitable for packaging fiat or thin articles, such as plates and saucers.

In Figs. 4, 5 and 6, however, I have illustrated a modified form of blank and carton formed therefrom, in which partitions are provided which run transversely with respect to the central or base panel. This form is suitable for packaging articles, such as cups, jars, cans and the like, which are not fiat or thin.

In this modification of my invention, the blank is provided with a central panel IEI defined by score lines I02, I83, I64 and IE5. Along the score lines I02 and IM the panel II is adjoined by end panels I06 and. I01, respectively.

The panel I36 is in part defined by score lines H38 and I99 forming extensions of the score lines I33 and I05, respectively.

Along the score line I08, the panel IE6 is connected to a spacing panel I I0 having a notch H I therein and which is adjoined along a score line II2 by a partitioning panel H3. The latter is in turn adjoined along a score line I I4 by a spacing panel H5. Along the opposite score line I89, the panel I36 adjoins a side extension panel H5 having a notch I I7 therein.

Similarly but oppositely, the side panel I32, which is partly defined by score lines H8 and I I3 forming extensions of the score lines I03 and Hi5, respectively, is adjoined along the score line I I8 by a side extension panel I23 having a notch I2I, and along the score line II9 by a spacing panel I22 having a notch W3 and terminating at a score line I24, where it is adjoined by a partitioning panel I25. The latter is in turn adjoined along a score line I26 by aspacing :panel I21.

Adjacent to the-panel .IOI along the score lines I03 and I051 provideouter side panels 132 and 133, respectively, which terminate atscore lines I34 and Iwhere they :are met by cover flaps I30 and I31 having notches I38 and I39, respectively,

The carton is brought into the condition in which it is shown in Figs 5 by making right angle bends along the score lines II4, "I112, I08, I00, I02, II8, I26, I24, H9 and I04,.and interlocking the notches I I I and I23 with the notches HI and 1, respectively. A' partial enclosure,

open at the top, is formed, having three compartments separated by. the partitions formed by the panels II3and I25. The side panels I32 and I33 and the cover flaps I36 and H41 are then brought up and over the partial enclosure formed in part by the panels 6, I06, I20 and I01, and by'interlocking the notches I38 and I'30,-the carton is completely formed and the enclosure completed, as is shown in Fig. 6.

Roughly, the dimension 1 of the panels I32 and I33 should equal the dimension m of the panels I06 and I01; the dimension n of the panels H3 and I25 should equal the dimension o of the panel IOI; the dimension p of the panels I I0, I I5, I22 and I27 should be equal to one-third the dimension q of the panel IOI and the dimension 1, n and 10 should correspond to the principal outer dimensions of each of the three articles or units intended to be packaged in the carton;

It will be obvious to those skilled in the art that my invention is capable of considerable 'modification in detail within the skill of the art,

and is therefore not limited to the illustrative examples given hereinabove, but is to be broadly construed withinthe scope of the claims hereinafter made.
