Patented Feb. 5, 1952 Miilaein. 11owzi1,foiinon, N. 11.,.sssino 'tomilpire Box Corporation, Garfield, NL,J.,`a corpo- This invention relates to egg cartons. More specically, this inventionrelates to 'egg vcartons which are made from asingle blankwhich is cut, scored or creased, andlglued; to form-:a unitary egg carton. The general construction of the egg carton which forms .thersubjectfmatter of the present 'application is disclosed Aand claimed in the application of VWilliam H. Allen Von Egg Cartons'filed March v121, -1945, Serial No. 583,988,y

rAn object of the y.present inventionfis to lmodify the'construction disclosed -in the aforesaid application of William H. Allen, Serial N. 583,988, so as to pro'vide anegg carton of .the A`general character therein -disclosed and claimed vbut which may be divided transversely so as to form two complementary egg 'carton sections each adapted to contain six e'ggs 'arranged in two rows each containing Athree eggs. The purpose and general utility of such transversely divisible egg cartons 'is well known in the art A'and hence need not be described in detail here. y

.Another object of' the invention is to .provide in the blank from which thenew egg'V carton is formed`A a novel 'construction and `arrangement of the transversely extending 'and 'depending end walls or end aps Vfor retainingv the eggs in the two complementary egg carton sections after the original 'carton containing a dozen eggs arranged in `two rows of` six eggs has been divided transversely. i

An additional object rof the inventionis to con'- struct the end walls orend flaps whichare em'- bodied inthe new egg'cartonin such ajmanner that the said end 'apsor end walls resistswinging outwardly beyond the vertical .planes 'in which they vare'disposed when the carton is in erected condition so thatl if there should occur a tearing :or rupturing Iof the relatively narrow.' end walls or end aps which are iormedfin the bote tom wallsections of the carton, immediately outwardly of the slots which are adapted `to receive the lower 'end'portions offthe end apsythe said end flaps will by reason of their't'endency to resistoutward swinging movement still effectively retainthe'eggs in theend cells orpockets offthe carton.

Still another object of ther invention isf'to construct the 'new egg carton so that it is of the transversely divisible type bui-,embodies the novel` construction and advantages; referred to in the immediately preceding object in all four end walls or `end flaps vwhichare embodied in each ofthe twin sections -formed by the/transverse division ofthe new egg carton.- ,f v

. A further object of the invention-is t'o'construct y Vzcams. (Crm- 28) ..2 I the end waIlsor end-naps in the new ees leek ton in such a manner that vthe said vgendv naps and the fold line hinges by which 4theyjare--fsupported-in position of use possess asignieantly greater resistance to tea-ring under the pressure of the eggs in the'end cells of the cartonithan is possessed bythe end walls or vendilaps in prior egg cartons and by reason Loi. which @one struction of the mend flaps and theirsuppoijting fold line hinges the` said end fflaps willfeiectively prevent the-eggs '-in the end-cells of -the carton,

both before and after itis -lseveredfrom-falling out of the endcells if the-'relativelynarrow web portions which denne the outside walls :of the slots inthe bottom wallof thecartominto which the lower en d portions-of .the end flaps are extended should be torn or ruptured :.inuse, An additional object .of the present invention is to providey a transverselydivisibleiegg `-carton in which all ofthe' eight gend vwalls or endflaps embodiedy therein 'aregformed in the `blanken#A tirely withinthe parallel side ormarginal edges of the substantially rectangular "blank,l rather thanin -wholevor in part' by portions of fthe blank which project outwardly beyond the .parallelfside or marginal edges ofthe blank, as hasbeen'the customary practice heretofore in the artof transe, versely divisible egg cartons, s othat a-'distinct economy is effected `inthe amount ofpaperboard required in the manufacture of the `new trans# versely divisible @egg carton as comparedtoprio1' transverselydivisible egg cartons of facomparable character. Y

, Other 'and further objects of thepre'sent'im vention will be apparent from the Vfollowing del scription and claims and are illustrated in ythe accompanying ldrawings which', Aby way of illus;A trationl show preferredem-bodinlen'ts of th'eepresent invention and thezprinciplesthereof and what I fnow co'nsider 'tube =the best mode li1'i` `which I have contemplated applying these principles;A Other embodiments =of the vinvention ei'nbodying the same Aor quivalentsprinciples may blused and structural changes may be ma'de 'as Adesired by those skilled in the artl without" departing*from4 they present invention and thezpurview of the appendedsclaims.y

As shown in Fig. 1, a so-calledglue strip 25' is integrally connected to the longitudinal partition-forming and transverse' partition-forming and end Hap-forming section 2| .at one end of the blank I0.

' -V The vblank I0 also includes a front wall section 95 which is hingedly connected to the bottom Wall section I2 along and by means of a fold line 96. Formed'in the bottom Wall section II is a row of spaced openings 26, 21, 28 and 29 which provide partially cut-out tongues or tabs 30,V 3|, 32 and 33, respectively, these tongues or tabs 30, 3|, 32 andi33 being hingedly connected to the bottom wall section I2 along and" 1by means of lthe fold line I3. Similarly, a row of correspondingly shaped openings 34, 35, 36 and 31 are formed in the portion 2310i the center or longitudinal partition-forming andtransverse partition-forming and end flap-forming section 2| and these openings 34, 35,.36,and.31 provide .partially cutoutftongues or tabs 38', 39, 40 and 4| which are similar and 'complementary in shape to the tongues 30,.3|, 32. and.33,`respectively. TheseA 4 tongues or tabs 38, 39, 40 and 4I are hingedly connected along the fold line 24 to the portion 22 of the center or longitudinal partition-forming and transverse partition-forming and end ilapforming section 20. Also provided in the bottom wall section are openings or slots 42, 43, 44 and 45 and similar openings or slots 46, 41, 48 and 49 and are provided in the bottom wall section I2. As shown in Fig. 1, the slots 42 to 49, inclusive, are oblong in shape and their long axes extend at an acute angle relative to the parallel side edges S of the carton blank I0, for a reason which will be pointed out hereinafter. The arrangement of the Aslots 42 to 49, inclusive, is such that a relatively narrow web |82 is provided outwardly Iof each of the slots 42, 45, 46 and 49 in the corresponding bottom wall section II or I2 and a similar web |83 is provided adjacent each of the slots 43, 44, 41 and 48 (Fig. 1). As shown in Fig. 1, these webs |82 and |83 are somewhat wider at one end than at the other end thereof. Y Formed in the center or longitudinal partitionforming and transverse partition-forming and end flap-forming section 22 are four end walls or end flaps 50, 5|, 52 and 53 and four similar end walls or end flaps 54, 55, 56 and 51 are formed in the center or longitudinal partition-forming and transverse partition-.forming section 2|. It will be noted, in this connection, that all of the eight end aps 50 to 51, inclusive, are formed entirely within the -connes or marginal edges of the blank I0.

Also formed in the center or longitudinal partition-forming and endflap-forming section 20, between the end Walls or end flaps 50 and 5| are a pair of transverse partitions yor egg cell dividers 55 and 56 and a similar pair of transverse partitions or egg cell dividers '51 and. 58 are formed between the endwalls -or end ilaps 52 and 53. Similarly, a pair of transverse partitions or egg cell dividers 59 and 60 are formed in the longitudinal partition-forming and transverse partition-formingland end flap-forming section 2| between the end flaps 54 and 55, and a similar pair of transverse partitions 6| and 62 are formed in the section 2| :between the end walls or end aps 6| and 62. i.

The end Wall or end llap-56 also includesV aV triangular-slfiapedy laterally projecting portion |12 and this triangular-shaped portion |12 is connected by a fold line |13 to the'main body portion-of ,the end wall or flap 56. The triangular-shaped portion |12 of the end Wall orend flap V|12 is hingedly connected by a fold line |14 to a triangular-shaped web |15Which, in turn, is connected by a fold line |16 to the portion 213 of the center and longitudinal partition-forming section 2| of the cartonfblank l0.

Similarly, the end Wall or end ap 51 is hingedly connected by a fold line |44 to a tri,- angular-shaped web |55 which, in turn, is connected by a fold line |66 to the glue strip 25. The end Wall or end flap'51 also embodies a triangularshaped laterally projecting portion '|41 which is connected by a fold line |48 to the mai-n body portion of the end Wall or flap 51 and this triangular-shaped portion |551 is hingedly connected by a fold line |419 toa triangular-shaped web |50 which, in turn, is connected by a fold line |5| to the portion 23 of the center and longitudinal partition-forming section 2 Vof the carbon .blank I0. t

As shown in Fig. l, the portion 22 of the center and longitudinal partitions-forming section `20 of the carton blank 0 includes a row of-spaced cover-supporting portions or tongues |52, |53, |55 and |55 and the portion 2?. of the center and longitudinal partition-forming section 2| of the carton blank I0 includes a row of spaced cover- A supporting portions or tongues |56, |51, |58 and In assembling the carton blank shown vin Fig. 1 the upper surfaces of the bottom Wall-supporting tongues 30, 3|, 32, 33, 38, 50, Li0 and 4| l(as Vseen inthe blank shown in Fig. 1'8) are Aiirst coated With a suitable glue or other adhesive. The center or longitudinal partition-forming and transverse partition-forming andv end nap-forming sections 20 and r2| and attached glue strip l`25 are then folded, as a unit, along the fold line 91 so as to bring the adhesively'coated surfaces'of the bottom wall-supporting tongues 38, 39, 40; and 5| above and into contact With the adhesively coated surfaces of thebottom wall-supporting tongues 30, 3|, 32 and 33, respectively. During this rst folding operation the center or longitudinal partition-forming and transverse Ypartitionforming and end flap-forming sections 20 and`2| and attached glue strip 25 are held in raised position in a manner which is disclosed in the aforesaid application of William H. Allen. Y lWith vthe rparts disposed in a raised position, aicoat or stripe of glue or otheradhesive is applied to andalong thelongitudinal center areas of the adjacent portions 22 and 23 of the center or longitudinal partition-forming and transverse partition-forming and end flap-forming sections and 2|, respectively, of the carton blank IU. During this gluing operation the center or longitudinal partition-forming and transverse partition-forming and end flap-forming Vsection 2I-23, and attached glue strip 25, are held in a raised position relative to the then horizontally extending center or longitudinal partition-forming and transverseV partition-forming section 20-22 of the carton blank I0. The center o1' 1ongitudinal partition-forming and transverse partition-forming and end flap-forming section 2 I--23 and attached glue strip 25 are then pressed downwardly into horizontal position above and into contact with the center or longitudinal partition-forming and transverse partition-forming and end nap-forming section 20-22, thereby adhesively securing the glued areas ofthe portions 22 and 23 of the center or longitudinal partitionforming transverse partition-forming and end flap-forming sections 29 and 2|, respectively, together.

With the parts thus disposed, the then upper surface of the g`lue strip is coated with glue or other suitable adhesive, whereupon the center or longitudinal partition-forming and transverse partition-forming and end flap-forming section 26, and attached glue strip 25, the center or longitudinal partition-forming and transverse partition-forming and end flap-forming section 20, then disposed therebelow, and the then underlying front wall section 95 and bottom wall sec- :2, tion I2 are folded upon the fold line I3, as a hinge,

so as to bring the coated surface of the glue strip 25 into engagement with that portion of the rear side wall section I4 which lies adjacent to the fold line I1. During this final folding operation the then adhesively connected pair of bottom wall-supporting tongues 39-38, {M -39, 32-49 and 33--4I are rotated out of the openings 2-34, 21--35, 28-36 and 29-31, respectively, whereupon the said bottom wall-supporting tongues -38, {tI-39, 32-49, and 334| project laterally to one side of the fold line i3 which is disposed between the bottom wall sections II and I2.

The thus completely assembled or glued and folded carton is then disposed in a nat, collapsed condition, ready for stacking, shipment and use.

In order to erect the assembled carton from a flat, collapsed condition, into erected condition, in which it is shown in Fig. 2, it is merely necessary to pull the front wall section 65 and attached bottom wall section I2 away from the portion 22 of the center or longitudinal partition-r forming and transverse partitiomforming and end flap-forming section 20. This operation moves the adhesively attached portions 22 and 23 of the center or longitudinal partition-forming and transverse partition-forming and end flap-forming sections 2L* and 2|, respectively, and the cover-supporting portions or tongues |-I59, |54-I58, |53-I51 and |5|56 into a vertical position, parallelV to the front wall section 95 while, at the same time, vmoving the end downwardly, Vupon the fold lines |05-I I0, I20-II1, IBI-|66, I11-I25, I33|28, |4||36, |14--|69, and |49-|44, respectively, as hinges, and their lower end portions are projected through the angularly extending openings or slots 46, 41, 48, 49, 42, 43, 44 and 45 in the bottom wall sections I2 and I I, respectively.

The thus erected carton is then ready for the reception of eggs and when the eggs are inserted therein, in two rows of six eggs, the downward movement of the eggs into their respective egg cells or pockets causes the egg cell dividers or transverse partitions 55,-56-51--58-59--60-1- 6|-62, inclusive, to fold or swing downwardly along the fold lines (i4-63, 61-68, 1|-12, 15-V 16, -19, 84-83, 81-88, and 9|-93, as hinges, into downwardly extended and effective position.

The cover section I6 and attached latching strip I8 m-ay then be moved into closed position,

whereupon the thus iilled carton may be stackedr in a case of thirty dozen eggs for shipment, following the customary practice in the art, or otherwise used. Y

It will be noted that when the thus erected and filled carton, embodying the form of the invention shown in Figs. 1 to 4, inclusive, is erectedV and filled, the adhesivelyl attached pairs of bottom wall-supporting tongues 39-38, 3|-39, 32,- 49, and 3,3-4I project downwardly at spaced intervals along but below the fold line I3 between the bottom wall sections and I2 and serve as supporting elements which coact with the bottom wall sections II and I2 to support the longitudinal center portion of the bottom wall I ||2 in an inclined or raised and cushion-forming position, as shown in Figs. 2, 3 and 4.

It will also be noted that in the form of the invention shown in Figs. 1 to 4, inclusive, the end walls or end aps 59, 5I, 52, 53, 54, 55, 56 and 51,

- and the transverse partitions or egg cell dividers 55, 56, 51, 58, 59, 60, 6| and 62, inclusive, extend only half-way across the erected carton between the front wall and the rear wall I4.

It will further be noted that the fold line hinges |05, |20, IBI, |11, |28, |36, |69 and |44, by means of and upon/which the end walls or end flaps 50, 5|, 52, 53, 54, 55, 56 and 51, respectively, are hingedly mounted, extend at an acute angle relative tothe end edges S of the carton and extend from one side of each end flap to a point somewhat beyond the medial center line thereof. This arrangement is such Vthat when the end walls or end flaps 50 to 51, inclusive, are erected and their lower end portions extended into the slots 46, 41, 48, 49, 42, 43, 44 and 55, respectively,

- the corresponding elongated slot 46, 41, 48, 49,

42,4 43, 44 or 45 in the bottom wall sections I2 and so that the said end walls or end aps 50 to 51, inclusive, extend at an acute angle relative to the end edges S of the carton, rather than parallel thereto, as has been customary heretofore in the art. The arrangement of the fold lines M35-IIB, |29-H9, IGI-|66, ITI-|25, |28|33, |36-|4|, I69-I14 and |44-I49 on which the end walls or end aps 50 to 51, inclusive, respec-tively, are hingedly mounted, and the mounting of the end flaps at the inner sides of the triangular-shaped webs I06-I I I, |2I--I I8, |62|61, |18--|26, |34|29, |42-|38, |15-|10, and |50-I45, tends to prevent the end flaps- 50 to 51, inclusive, from swinging outwardly beyond their verticali Apositions.when unY carton yis erected. Hence: {even-though the relatively narrow webs |82 and; 18S-in thebottomlwall sections I|.-.

It willv further be seen thaty the. longitudinalcenter portion ofthe bottom Wall` I I.-I2. ist held in raised or inclined and.. cushion-forming posi--v tion, as shown in Figs. 2`, 3"Y and. 4, without being suspended from or engagedl and. held' in raisedA position by the endlwalls. or end flapsv5`0 to 51,. inclusive, ortlie transverse partitionsl or egg cell` dividers 55 to 52, or any of them.

As may also be seen by reference to.- Figs. 2,` 3 and 4', the cover section I5 isI adequately Supported by the adhesively connected cover-supporting tongues `I'Il"-I`03, I53--I5'I, I54-I58, and I02-I04, which are formed integrally with and as upwardr extensionsfof.theadhesively connected portions 22 and 23. of the center or. longitudinal partition-forming and' transverse partition-forming and end vnap-:forming sections and 2|, respectively. A`s shown* in` Figs. 3 and 4, theseY cover-supporting,l tongues IOL-IUS, E53-,451, I54-I58, and; `Ill2f|il4 project upwardly' above the upper edge of. the front' wall section S5fand to approximately-'the' heiglitfof-th'e upper edgeof the rear Wall=section I4, sotliat the cover section I6 will bear on resti upon the upper edges of said cover-supporting tongues when the cover section I6 is inclosed position and a load or downwardly acting force is applied thereto. Hence it will be seen that the cover section i6 is adequately supported against the weight o overlying and ,downwardly acting loads or forces which might otherwise tend to crush the carton from above, and as might otherwise occur when the erected and lled carton,v is vpacked and shipped. in a thirty dozen case, as is customary in the art. p Y f The-form of the invention shown in Figs. 5 to 8, inclusive, is, in general, similar in many respects tothe'form of the invention shown in Figs.v 1 to 4,. inclusive, andv hence those partswhich are ern. bodied in thegfform of vthe invention shown in- Figs. 5A to 8, inclusive, which are similar or com-- parablefto corresponding parts in the formof the invention shown in Figs. 1 to 4,. inclus ive,rhavel been: given similar reference `numerals followed by the additional and distinguishingreference character az However; the form-ofthe invention shown inFigs. 5to 8, inclusive, differs from: the form of the invention shownY in Figs. 1 Vto 4,v inclusive, inv several respects, amongv w-hichr are the fact that-in the form of the invention shown in Figs. 5 to 8, inclusive, both of the angularly ex@ tending.v foldi lines 10M-Illia, I-ZIJa-I Ha; I6Ial66a, ITIa-I25a, I33a-I28a, I4Ia-I36a, Ilm-46911, and I4-9a-i44a, which provide' th'e' hinges for the endwalls or end flaps 50a to 51a, respectively, arey identical in length' and formation so that loothv of thei triangular-shaped webs IiOIa-IIlag I2Ia-II28a,.

This, are: rangement is such that when the endiiaps a to" 51a are in Yerectedl position the vertical planes=in= which: they are disposed.v extendparallelto the' endedgesof the carton" rather thanY atan angle'A relative` thereto asf do'the end flaps inthe' form of" the invention shown in Figs.V 1 to 4, inclusive;v

Therfornrof theinvention shown in Figs. 5 to 8, inclusive, likewise Idiilersfrorn the 'form of the iventiorr than in Figs. l1 to 4,-inc1usive, in-that in the form shown in Figs. 5 to 8, inclusive,the`f' slots 42a to 49a, inclusive, in the bottom? wall's'ctions I-.Ia and: I 2a extend parallel tothe endvedges ofthe carton rather than at an` angle relativen thereto as do'v the slots 42Z to 49, inclusiverin' the form' of the inventionv shown' in Figs'. '1"-to '4; in# elusive Y Moreover, the form of the invention`-shown'in Figs. 5 to 8", inclusive, differs from that shown' in: Figs. 1 to 4, inclusive, in that in theform of'the invention shown in Figs. l5y to :8, inclusive, the cover-supporting elements or tongues I"''I 59, I54-I58, I53f-I5T' andv I52--l5li/ which are'fem-i bodied' in-theform of the invention shownY in Figs. 1vv to 4, inclusive, are' elininate'diand the "ina-'-1 terial or stock employed? in` 'making these cover;Av supporting elements ortongues isl incorporated into andV embodied i'n the endA wallsor end` flaps 5Il`ato 51a," inclusive,of`theicarton shown Figs',v 5\ to' 8, inclusive. Hence itwill be seen that the' carton shownin' Figs; 5- to 8, inclusive, embodies v only two pairs of cov'eresupporting elements or i to' 4, inclusive, in that the-endfwalls or endiflaps pletely across each end flap from end to end thereof parallel to but in spaced relationship relative to each other. These reinforcing ribs |80 and 18| materially strengthen and stiffen the end walls or end flaps 50a to 51a which are embodied in the form of the new egg carton shown in Figs. to 8, inclusive, and thus tend to prevent the end flaps 50a to 51a, inclusive, from swinging outwardly beyond the vertical planes in which they are disposed when in erected position so that even though the webs I82a or |830, in the bottom wall sections Ila and I2a should become torn or ruptured, for any reason, the end flaps 50a to 51a, inclusive, will resist outward swinging movementV and hence will retain the eggs in the end cells or pockets.

It will also be noted that in both forms of the new transversely divisible egg cartons shown in the drawings, all the end flaps or end walls are formed so that they lie entirely within the parallel side marginal edges of the body of the substantially rectangular-shaped carton blank rather than projecting outwardly, in whole or in part, beyond the vsaid marginal side edges of the blank as has been customary and necessary heretofore inmaking transversely divisible egg cartons of -a comparable character so that a distinct economy is effected in the amount of paperboard employed in making the new transversely divisible egg carton.

It will thus be seen from the foregoing description, considered in conjunction with the accompanying drawings, that the present invention affords new and relatively simple egg cartons which are economical in manufacture from the standpoint of material or paperboard stock required to form the blanks from which the new egg cartons are formed and assembled, land otherwise, and that the invention thus accomplishes its intended objects, and has the desirable characteristics and advantages, including those hereinbefore pointed out and others which are inherent in the invention.

I claim:

1. An egg carton having two rows of egg cells with six cells in each row formed from a single substantially oblong shaped blank which `is scored along the longitudinal center line thereof so that it may be divided transversely when the carton is erected and filled to form two smaller but complementary and complete egg carton sections each having two rows of egg cells with three egg cells in each row, said blank being cut, scored, glued vand folded to' form the carton, which in its erected condition includes a front side wall, a rear side wall, a bottom wall -including a pair of integrally connected bottom Wall sections arranged between said front wall and said rear wall and inclined upwardly from their outer edges to the longitudinal center line of said bottom wall of the carton and providing a raised cushioned bottom for the carton, each of said botton wall sections having a slot therein near each end thereof and a slot at each side of and` near the longitudinal center score line of the blank, said slots extending transversely relative to the longitudinal axis of the bottom Wall of the carton, a cover, a glue strip attached toV one of said side walls at the inner side thereof, a pair of central longitudinal par-l tition-forming and transverse partition-forming and end flap-forming sections each comprising a vertically extending longitudinal portion and a part extendingr laterally from the upper end of the vertically extending portion, the vertically extending portions of said pair-of sections being disposed face to face one against the other and being integrally joined at their lower ends to form a central longitudinal partition, said longitudinal partition and the bottom Wall each having downwardly projecting tongues integral therewith at each side of the longitudinal score line of the blank, the tongues of the longitudinal partition wall being disposed against and adhesively secured to the tongues on the bottom wall for retaining'the'longitudinal central portion of the bottom wall in raisedV and upwardly inclined cushion-forming position, the laterally extending portions vof 'said pair-of sections'having parts thereof folded downwardly at each side of the central longitudinal partition to form end flaps having their lower end portions projecting through the slots in the bottom wall of the carton, and said laterally extending portions of said sections having parts thereof folded downwardly at each side of 'the longitudinal partition in longitudinally spaced relation with each other and with said endr flaps, said pair of sections being joined at the outer edge of the laterally extending portion of one of the sections to the side wall of the carton which is opposite to the side wall to which the glue strip is attached, and said pair of sections being joined to said glue strip at the outer edge of the laterally extending portion of the other section, the end naps of each of the complementary sections of the carton and the transverse partitions therebetween when the carton is divided forming with the central longitudinal partition two rows of egg cells with threecells in each row.

Y 2. An egg carton as' defined in claim 1 in which the said slots inthe bottom wall of the carton are elongated with-their long axes extending at an acute angle relative to the end edges of the carton, and which includes means formed in the said lcarton blank for hingedly mounting the vsaid end aps at their upper ends and the said` means for hingedly mounting the said end aps maintainA eachr of the end flaps in a substantially Vertical position but in a plane substantially parallel to the long axis of that one of said slots in the bottom wall of the carton into which the lower end portion -of the said end flaps is extended when the carton is erected and the said end aps are in downwardly folded and eiective position.
