Patented Mar. 16,- 1937 UNITED STATES PATENT OFFICE oAn'roN Samuel BergsteinQCincinnati, Ohio v Applicata@ June 11, 1934, serial No. '730,001 1s claims. (01229-29) My invention relates to cartons winch are made up andl stored and shipped in knocked down, -partially assembled condition. vOne particular application of my invention 5 illustrated herein is to cartons for packing and shipping eggs. This carton employs an innerv cellular holder with cells or compartments whereiti-thev eggs are held in rows longitudinally of the holder `with an inverted channel opening at the 'lower side of the holder between the-rows of egg compartments. It is the outer venclosure whichl is theparticular subject of my invention; the inner compartmented egg holder. not being' original withs mewnor a part of this invention, except as a cooperating element with the n'ovel exterior structure. Y

`One of the objects of my invention is to provide, in a very simple form, a knock-down outerI -container which may be made rapidly by machinery and will require only the simplest manipulation by the user to `erect it and make it ready for the receptionof the inner egg holder with the eggs.

A further object is to provide such an outer container with a partition or partitions between the rows of eggs, with the lower edge or edges of the partitions vbearing on the top of the insidecompartmented holder; 'thus providing a sup- `port for 'the top of the carton 4at a position or positions intermediate of the side walls of the. carton to ,which the edge portions of the top are attached. j

I also provide the outer container of this character with means formed lon its bottom whichl Will extend up into the inverted channel opening -at the bottom of the inner egg container to prevent the inner container from sliding out through either end of the outer cbntainer. In my copending application, Serial'No; 714,678, iiled 40 March 8, 1934, I disclose an inner container held in the outer container by means; such as that just described.

Inthat disclosure, the innerholder is of the height of the `interior of the outer container orcarton, so that it, by a ridgebetween rows"A of eggs, provides the intermediate support ofthe top ofthe carton, and also provides a partition between rows of eggs. My present improvement makes use of an inner containerwhich is of -the same character as, but is not as high, as the one in the prior application just mentioned. These inner containers are pressed integrally'of pulp; and the decreased depth greatly facilitates their formation, as well as saves a great amount of pulp, The partitions depending fromthe top -four each.

do not contain nearly as much material asthat say by makingthe inner container only a fr tion of the height of the interior of the outer container.

My invention is applicable to cartons which do lnot hate inner containers such as above described, but in which the articles packed simplyA engage top, bottom and sides of the interior of the carton, and require 'one or more partitions, according to thejnumber of articles in a series Vacross the container, so" as to separate the articles and cushion ,them from each other. In such a case the depending partition or partitions may be long enough to reach to the bottom of the carton. When` so provided, the partitions are supported by the articles between them against lateral buckling, and so may ailord' effective lb'racingmeans between the top and bottom of the carton. As an example of this latter application of my improvement, I show-it as a carton containing three bottleslying alongfthe carton side by side in a series across the bottom.

My invention also Aincludes the provision of a single piece blank so formed as to be adapted to be folded' and have parts. of its folds secured together by rapid continuous passage through a carton making machine, and which will pass from the machine in completed knock-down fiat condition,` whereby .it is adapted to be set up in the formof a tube, and `to Ahave its partition or partitions folded down :from its top to depend therefrom in relation to the contents of the carton as before described.

`One desirable form of egg carton is one in which a dozen eggs are packed in three rows of Another widely used form' is one which the dozen eggs are in two rows of six each. I disclose hereinan example of each of said forms, constructed according to my invention, but it will be understood that I am not limited to either form nor to the packing ofany cer.

' tain4 number of eggsin one carton. 1 As an Vexample of an embodiment of my invention for packing articles other than eggs, I dis- 'close a carton containing three bottles; but it will be'v understood'that I am not limited to the packing rof bottles; and that any article that can be conveniently packed with the use of my improved carton, either without an inner container, as when the bottles are packed, or with an inner container,

either cellular for packing as the eggs are packed, h; .or of other form according to the articles it is to contain, will be within the scope of my invention.

,Objects other than those above mentioned will occur in the course of the following description,

'In the example of Figs. 1 to 7 inclusivelrthe blank I is of simple elongated rectangular formation with transverse scores 2, 3, '4, 5, 5, and 1. Between and parallel with the scores 5 and 1, and closer to -Score 5 than to score 5,' are transverse cuts 8, 9, and I; the middle one 9 being 'much to these other twocuts 8 and III by short lines of perforations II and I2 respectively. For reasons which will later be described, these perforations are such that the twoparts of the blank are almost severed, and the perforations will allow complete separation'under relatively slight pressure.

The space between scores 3 and lis to form the bottom part I3 of th carton; and at its center it has an H-shapedcut to forni two .tongues I4 whichare in meeting relation, and which Vxhave scores I in alinement from the lmeeting ends of the tongues to transverse scores vI5 atthe ends of the H-shaped cut.

The :narrow portions between scores 4 and 5 are to form the side walls I1 and I3, respectively, of the carton. The end portion of the blank vat the left of score 2 is to -form the top I3 of tha u carton; and it has at each end in the opposite longer than thel other two, and being connected -laterally outer rows.

edges of the blank, two recesses 2 I, one near each corner of this top forming portion I9.- d

'I'he end part of'the blank at the right of the cuts 8, 9, and I0 and perforations and I2 is to form the two partitions 2| and 2| and a junction member 22, between scores 6 and 1, for these partitions 2| and 2|. l l The narrow space between score 5 and the cuts 8, 9 and I Il and perforations and I2 is to form a flap 23 to which the left hand edge portion a of the top forming member I9 is to be secured in. the completed carton, while the middle junction portion 22 for the partitions 2| and 2|a is secured along the middle area of this topjforming member I 9.

I'he blank above described is adapted to be carried along in a carton making machine, of well known construction, which rst makes a fold at the score 4, turning that portion pf the blank at the right of this score 4 over onto the left hand portion, asseen in -Fig. 2. 'I'hen upon further travel, adhesive 24 is applied to the surlface of portion 22 now lying upward and adhesive 25 is applied to the surface of narrow portion 23 now facing upward, as also seen In Fig. 2. Upon further-travel the machine makes a fold at the score 2, bringing the top-forming portion I9 over onto the -portions previously folded, and the folded blank is then, upon further travel, subjected topressure so that the left hand edge portion a is caused to adhere to the narrow portion 23 by the adhesive 25, and the middle area b of the top I9 is caused to adhere to the portion 22 by the adhesive 24. 'I'he knockdown carton is now completed as seen in Fig. 3.

When the'contents are insrtedinto this carton, it is pressed into open tubular shape as seen in Fig. 4." `In bringing the carton into this shape, folds are made at scores 3 and 5, with partial unfolding at scores 2 and 4. The partitions 2| and 2|' now lie flat up against the under side of the top I3, along with the middle portion 22 and flap 23 to which they are attached.

To bring these partitions 2| and 2|' downv into depending vertical positions as shown vby the dotted lines in Fig. 4, all that is necessary is to support the carton by the lingers ofthe two handsv other than the index fingers, under the ends of the carton, and press with the index fingers and 4thumbs in the recesses 2li, down against the partitions 2| and 2|'. The partition 2| willreadily break loosefrom the fiap 23 under this pressure, tearing the material at the perforations and I2; so that it bends down practically as easily as does the free partition 2|. 'I'he partitions swing by folding at the scores 5 and 1.

The inner container 26 has the twelve compartments or cells 21.in three rows of four each, with web portions 28 that join the upper rims of these cells' 21, so that there are two`rows of' :thesewebs 23 longitudinally of the container/25.

container, with theeggs E in its cells 21; whereupon the bent down partitions 2| and 21' are received between the middle row of eggs and the TheL outer carton is high enough interiorlyv to receive the eggs with very little vertical play; the middle row of eggs preferably fitting snuglyunder the Junction strip!! of the-partitions, as seen in Fig. 6. The partitions rows of web portions 28 `of the Itop of the inner container 26, before mentioned.

The integrally formed cellular inner container 261s amply rigid, and with this support of the partitions 2| and 2|', the top and bottom 9 and I3 of the outer container are amply braced apart, so that the top I9 is especially supported in its middleportions, against impacts that would otherwise cause it to' yield, with possible breakage of the eggs E. At the same time the partitions 2| and 2| depending between the eggs, form cushions between the upper parts of the eggs that extend'up out of the cellular inner container 26. As previously explained, this allows this inner 5 container to be of reduced depth, about hal-'f that Cat of the inner container shown'in connection with my invention of the prior application mentioned. 'I'he inner container thus is very much less expensive, and the partitions 2| and 2|', taking the place ofthe omitted upper structure of inner container, add to the cost of the outer container only a very small fraction of what is saved from the inner container. l

When the innercontainer 26 with its eggs E have been positioned as above described, the -iiaps lli are bent up from the bottom 3 of the outer container into spaces 29 between the'middie two transverse rows of cells 21, as best seen in Fig. 7; the aps or tabs Il hinging at thev scores I6, and also buckling along their scores l5 until their upper ends are jammed into the spaces 29 in a retentive manner. These flaps or tabs I4 -thus will prevent the inner container 26 D from sliding out ofthe outer containerlaccidentally. The inner container may bewithdrawn =to remove the eggs, by pulling out these tabs I4,- or by simply pulling so forcibly on the inner container that the tabs I4 are torn or forced out of the spaces 29. vAfter this the inner container with part of the eggs left in it will -be held suiliciently by friction4 withthe walls and partitions of the outer container, until the eggs are all used. Of course the outer container may be disrupted to get the eggs out; but the user usually prefers to preserve the carton in closing condition until the dozen eggs have all been used from it.

The most notable diilerence of the tabs Hi from the tabs in my prior application mentioned. is their disposition across the container instead of lengthwise of it. This is dictated by the different arrangement of egg cells 26, three rows instead of two; but the tabs disposed in this'way have a somewhat better holding engagement against sides of egg cells than the longitudinally disposed tabs, so that they hold the inner container and eggs more rmly in the outer container than the longitudinally disposed tabs do. It may be said that the .three-by-four egg carton is generally more substantial than the two-by-six egg carton,

inherently; and this firmer bracing by the retainV ing -tabsjll is an added advantage of it;

permitted'by the three-by-four arrangement.

Myl present invention. is well adapted. to thetwo-by-Six egg carton, however, as shown in Figs. 8 to13, inclusive. As only two rows of eggs are involved,of course only one partition is needed; so that the readily detachable connection tothe connecting flap of the carton tube is not needed. As-shown in Fig. 8, the more nearly square blank la lhas only ve transverse scores 2a, 3a, la, 5a, and 1a, instead of six as in the lirst example. These dei-lne, from left to right as illustrated, a top portion |9a, side wall Ha, bottom Ila, side wall |8a, portion 22a `which becomes part of the top and is the attaching portion for tneparntion, and, iinally, this partition 2Ia. I r The making of this carton by continuous move ment through a cartonmachine is practically the same as that described for the first example.

rfor. pressing down the one partition 2| a to the position indicated `by dotted lines in Fig. 11. The vinner container 26a has two rows of six cells 21a each, with a row of top webs 28a joining .the two rows of cells, uponwhich row of webs the lower edge of the partition 2|a rests, with .the advarr4 tages of the first example.A

Also, for this two-row carton,`the bottom tab Ma extend lengthwise, and are spaced lengthwise, to enter the spaces 29a. between the mid-v dle group of four cells and the outer two groups, as best seen in Figs, 12 and 13.v They hingeat scores |6a, and buckle at scores |5g to crimp intorthe spaces, in the manner described as to the rst example. The spacing of the tabs, leaving a portion c'of the bottom' |3a between them, is an arrangement diiferent from that ofthe bottom tabs in the two-row carton of my prior application before mentioned, because the inner cellular container 26a is only about half as deep as the container in the prior disclosure. The ytabs have to be at the same relative locations, but cannot belong enough to'meet, and be. made by an H-shaped cut as in the rst example, or a somewhat similar cut in the prior` disclosure. The shorter tabs, here, or in the iirst example, are stronger than the long tabs of my prior applica- .tion mentioned.

necting flap joining the top of one side wallV as'` in the previous examples; but is attached directly to the top of thesi'de wall. The ap to attach for completing the tubular shape of the carton :is attached to the outer edge portion .of the top f' forming portion of the blank, and laps down outside and is attached to the upperv portion of the side wall to which the partition is attached. As a bottle carton, it is illustrated as being made of three-piy board of which the middle ply is I.

corrugated; material well knownv for such purpose. There is of course no limitation as to the nature of material of sheet stock used for any of the cartons. i

'I'he blank Ib isv shown in Fig. 14, with six scores 2b, 3b, 4b, 6b, 1b, and 5b; the last mentioned score, 5b, not-being in the position of the score 5 of the irst example,` butt` being the rst one to the left as shown', as the folding line for the connecting ap 23h joining the left hand edge portion a" of the top forming'p'ortion |9b of the blank. The long and shortcuts lb and 8b and I b, with intervening perforations IIb and I2b are like those of the first example, but are about- Ila of the rst two examples, are provided; aly

though it will be understood that such tabs, br other suitable tabs may be provided in the bottom if the shape of the articles packed facilitates their use. Y Fig. 15 shows the first stage of folding of the blank, with bands of adhesive 2lb and 25b'applied, respectively, to the junction or attaching portion 22h and an area of the side wall l|81 along next to the cuts and perforations', to which is` to adhere the flap. portion 23h, as shown in the lsectional view, Fig. 17, when the final folding is done to make the knock-down carton, which stage 25 is notillustrated for `this example. but will be understood from the corresponding illustration in Fig. 3, for the first example. Junction portion 22h adheresvto the middle area b" of the underside of the top |91); and the partitions 2lb and 2 Ib' are turned down with the thumbs and fingers inserted in the recesses`20bas described for the first example. 'I'he bottles B may be slipped into the compartments defined between partitions and between partitions and sidewalls of the carton,

5 as seen in Fig. 16. The bottom wall Hb may lhave the middle portions of itssends crimped up befl tween the adjacent end portions of the partitions 2| b and 2lb', as seen at d, d, Fig. 16, in dotted lines; this crimping itself preventingv easy sliding i0 of the middle bottle from the carton,` and the lateral spreading of the lower corner portions of the partitionslserving a like purpose for the outer in a container also' contained in the carton, which container extends only a fraction of the distance 55 from one opposite wall-to the other, said carton comprising a straight edged'partition' to extend between articles extending. past the inner -container and held against said inner container in bracing relation between the opposite wall of 60 the carton and the surface of the inner container facing said other wall.
