Mr WW- is. subdivided to. separate quantities one another.
United States Patent Allied-Plastics Company, has Angeles,.Calif., a corporation of California Application February 28, 1956, Serial No. 568,407 6-Claims. (c1. 229-47 The present invention relates to improvements in a paperboard shipping crate intended to supplant the widely used wooden lug in the long distance shipment of fruits, vegetables and other produce- The crate illustrated herein. has been specially devisedfor the shipment of grapes; however, it is also well suited tohandle other equally and even more perishable commodities. It is fabricated exclusively of corrugated paperboard stock, preferably treated by impregnation to render it strongly moistitreresistant, which is an important factor in the maintenance of the inherent, built-in strength of improved crates. The reason for thisis that they are commonly, in fact practically exclusively, used under very severe atmospheric conditions, i. e. in refrigerated railroad cars or trucks at high humidity and low temperature, such as would rapidly deteriorate an 'untreatedunit. They receive rough treatment in use, beingstacked high and jammed in'place in transit, to severe jars and pressure and are handled roughly, to say theleast, at the points of origin and end of shipment. Under conditions of this sort it be 'om'es extremely important to incorporate in a paperboard crate'for such intended service all possible provisions to rigidity and strengthen the same, yet which can be resorted to-without unduly and uneconomically increasing its cost of production.
Ihave foundthatthis strengthening can be accomplished, ina considerable part, by utilizing among other things, certain provisionsby which thetimproved crate of "crated fruit from To. this end theinvention avails) l itself in a novelmannerof .a. central cross partition .of the crate and themeans whichsustainthe. sameagainst lateral shift, wherebyptoadd substantially jto the. rigidity. and strength of the, ,cra'teas tawhole. The sustaining means referred to also servesto cushion thercommodity .received in the subdivisions of the crate, thus minimizing ma e in ipm t; dth ustai ed P t on t as a central support fo r a cratecoyer, which increases the capacity of the crateand alsov has a ventilating function.
The partitioning means accordance with the invention comprisesj a pair of panels which are integrally hingedto one another bya top crease, "and which are integrally connected to si walls .or the crate by connectingwebsatopposite end and sides of this crate. These panels extenddownwardly,inupright position, constituting with their connecting webs a beam-like support across the crate. Thegpartition panels are held fixedly in this position by a pair of medially creased corrugated board sustaining inserts, which inserts are arranged in a manner to space their two constituent bottom and end panels slightly from the bottom and end of the crate. Since the contents of the crate are disposed directly on thein'sert panels, the same serve as cushioning elements for fruit or produce packed in the. subdivisions of the crate.
More specifically, the described arrangement contemplates that abottomzor false floor of eachpartition sustaining insertrshall rest"on.-an-.outturned 'flapaona cross in shipment, the contents 'still remain visible the level of the side wall tops on arrival.

partition panel, with the edge of the false floor panel in abutting engagement with the adjacet surface of the partition panel, adjacent the bottom thereof, and with the crease which medially subdivides the insert in opposite engagement with a crate end wall at the bottom of the latter. When the inserts are in place in this fashion, one end of each resting on a partition bottom flap and the hinging crease of each wedged downwardly against an end wall, each insert is firmly secured in position to hold a panel of the dual panel cross partition against outward end movement. The partition is thus locked in proper upright position, and at the same time the inner ends of the false floor panels of the inserts are lifted somewhat above the true bottom or floor of the crate, thus to cushion its contents in either half.
Similar end cushioning is also provided by the inserts, for an upstanding panel of each inclines upwardly and inwardly slightly from the crease which connects it to the false floor panel of the insert. Its upper end is held inwardly in this position by a thickened top cross beam construction at the crate end. Being thus spaced inwardly of the end wall beneath that cross beam, the insert end panels contribute a cushion action ateach crate end to protect the fragile conte ts of the improved crate.
Yet another improvement resides in the provision of a set of inwardly extending spacer tongues on each of the outturned flaps of the cross partition panels, on which flaps the false floor panels of the inserts rest. These tongues are in the planes of the respective flaps and extend inwardly of the panel to which the fiapis attached; they thus have edge abutment with the other partition panel so as to space the two partition panels from oneanother. Thetongues of the respective sets are preferably staggered, or alternated with one another in the longitudinal sense, nesting or interfitting side by side when the partitions are in proper position. This fixes the desired spacing of the latter, whichis primarily for the purpose of cross ventilation, so that the individual capacity of the crate subdivisions is kept as great as possible; Openings formed in the partition panels in outlining the spacer tongues complete the ventilating provisions across the bottom and center of the crate.
Improved provisions are also made to cover the .crate, restraining the contents thereof fromspilling-oveifl-as well as protecting the s'ame from impact or pressure from a crate stacked above. The cover, like the crate,.is fabricated from corrugated board stock and is held :in place under bending stress to resist inadvertent displacement. The cover is centrally supported by the cross partitionof the crate and its connecting'webs,'referred to. above, and projecting lugs on its ends are registered in; suitable apertures in the multiple-ply end walls of the crate. These restrain the cover laterally and verticalily, and it is further held from upward movement by engagement of, the four cover corners withfour triangular corner'webs of the crate, which span the angles between its end and side walls. a
The cover arches upwardly from opposite. ends, so restrained, to and over the cross partition and associated webs, by which the cover is centrally supported. This permits grapes or other bulkfcontent's of the 'c'rate to be heaped well up above the. actual sidewallsfoithe container. A very copiouslyyet snugly packed, container is made possible, and, moreover, despite some settling and compacting of the grapes or other'prod'uce at ofaboye Hence the appearance of a generously filled container is preserved,
which is a strong factor-of psychological adv'antage;
The crate has the appeara' cc 'of 'a'container ofconsiderable vertical height, substantially greater at its elevated center and corners than the well-knownflug increase in the over-all height loaded crates. The reason for this is central Zones of the crate, at which when stacked one on top of the other, actual side walls of the crate no higher of the usual wooden strips or spacers which are employed to vertically space and ventilate stacked wooden lugs. The provision of an upwardly bow'ed,-centra1ly sustained cover for the crate provides ample top ventilation for the contents of a stack of the improved paperboard crates.
The end wall structures of the crate are built up of a plurality of corrugated board plies. These include the crate side walls disposed in cobut this does not entail an of a stack ofthe that the end and they, are sustained the thickness of the crate end at its The top of the end cushion panel of a partition bracing insert, described above, rests There results an end wall structure which has increased rigidity, due in part to the flap overlap, yet which is truly flat across its outer end surface. It

The foregoing statements are indicative in a general way of the nature of the invention. Other and more specific objects will be apparent to those skilled in the art upon a full understanding of the construction and operation of the improved crate.
A single embodiment-of the invention is presented herein for purpose of illustration. It will be appreciated that the invention may be incorporated in other modified forms coming appended claims.

Referring to Fig. 1 of the drawings, the improved crate is fabricated from a generally rectangular blank withstand the humid, a long distance shipping container for fruit or produce is called upon to face. It will be noted as the description proceeds that blank 10 requires little internal stripping of punched out stock, hence the crate lends itself to expeditious, cheap manufacture.
The blank is almost perfectly symmetrical about its theoretical longitudinal and transverse center lines. Accordingly, corresponding reference numerals are employed to designate corresponding parts or relationships has a free edge defined by the same slit 17, the flap 18 being integrally hinged to the remainderof sectionll by means of a transversely extending crease l9.
Longitudinally aligned, slot- like openings 20, 21 located at either side of panel 11 and 21, at creases 15, 19, the panels 16, as w for swinging-out of the plane of section 11.
The two inclined slits 22 11 are disposed on opposite sides of medial hinge crease 'all six webs 23, 24 coincide with the opposite side carton. Each zone 29 extends between and merges into the corner webs 24.
.in the completed crate,
Each partition forming panel 16 is provided, inwardly of its free end at slit 17, with a transversely aligned series of short creases 30 and with inwardly bowed, U- shaped slits 31 alternating with creases 30, the ends of the slits falling at the termini of the respective creases 30. There is thus provided a bendable friction flap 32 on the free edge of each panel 16 which is equipped with spaced, inwardly projecting tongues 33, as outlined by slits 31, for a purpose to be described. For the time being, it should be noted that the tongues on one flap and panel are arranged in longitudinal alternation with those of the other flap and panel. 1
Inner end wall flap 18 of section 11 is provided at its center point with a U-shaped slit 34, the inwardly extending ends of which are connected by a short but deep transverse cut-score 35, extending practically through the stock and constituting a readily bendable hinge for a small flap 36. This flap is adapted to be bent about cut-score 35 into side by side relation to flap 18, in the completed condition of the crate.
Finally, each end wall panel 27 of section 11 is provided with a shaped'hand hole 38 having an internal tab 39 hinged on its inner margin.
.Theside and end wall forming sections 12, which are integrally hinged to section 11 by aligned short creases 2 6, each comprise a side wall panel 40 articulated to those hinges, and end wall forming flaps 41 integrally hinged by transverse creases 42 to each end of panel. Cre'ases 42, parallel but are spaced somewhat inwardly, in reference to panel 40, from the line of the transverse creases 48 which hinge the end wall panels 27 on section 11. Side wall panels 40 are provided with ventilating apertures 43 directly adjacent a botto forming margin thereof, i. e., remote from their hinges Each of the flaps 41 is relieved at its outer margin and adjacent the panel 27 by means 'of a shaped notch 44, notch 44 including a curved hand hole bay'AS and an inwardly located transverse clearance cut 46. Slits 47in longitudinal alignmentwith creases 26 separate the end Wall flaps 41 from the end wall panels 27 of section 11.
Each of the bottom and end wall forming sections 13 is cornprised of a rectangular bottom forming panel 49, integrally hinged to a side wallpanel 40 by a longitudinally extending crease 50, and a pair of end wall forming flaps 51. These are integrally hinged to opposite ends of panel 49 by transversely extending, mildly inclined or slanted creases 52. Each crease angles inwardly from itsouter terminus on an extreme sideflrnargin of blank 10, which terminus is in approximate alignment with crease 42, to. an opposite end'located slightly outwardly of crease '42. The purpose .is to provide thickness clearance at a seam overlap of flaps '51 as will be further described. End wall forming flaps 51 are separated from flaps 41 by"slot's 53 of some width and flaps 51, like flaps 41,.are also provided with hand hole and clearance openings54 at their outer sides. The openings at one side ofthe blank, designated 54, have the same shape as the openings 44 of flaps 41, however the openings 55 at the opposite side of the blank are in the form of transversely extending, U-shaped notches or bays. r
The crate is completed to its fiat, knocked-down condition, shown in Fig. bottom and end wall forming section 13 upwardly, inwardly and downwardly 180 about the crease. 50, followed by alike folding of the other corresponding section 13,"along with the adjoining section 12, about the adjacent set of connecting web creases 26. This brings seam portions of the panels 49 into overlapped relation to one another, in which they are secured by a series of wire stitches or staples 56. In this flat condition the. crate is shipped and stored in a minimum of space.
The crate is. erected to the operative condition illus- 26 to webs 23,24. 3
2, by first folding the right-hand.
. face "enga'gementwith the'flaps when 8 by simply exerting compressive force on the opposite side margins of the flat article, represented by. crease formations 26 and 50. The several sets of end, side and bottom panels and flaps approach rectangular outline, and the article may be temporarily held in this outline by swinging partition panels 16 downwardly within side wall 40 about their hinge crease 15, to an approximately upright position in which their terminal flaps 32frictionally engage the bottom of the crate, constituted by panels 49.
In this position of the panels 16, the inwardly projecting-tongues 33 of the longitudinally.staggered sets on the respective panels will-serve as. partition spacers, each set engaging the other panel to brace the panels against one another and maintain predetermined spacing thereof. Yet the resultant upright partition, generally designated 57, is not of excessive width so as to consume undue space in the crate. Its panels are spreadonly sufficiently to afford desired interior cross ventilation space, which is communicated with the two subdivisions of the crate, at the bottom of the latter, by the series of openings 33 left by the excision oftongues 33 (see Figs. 3 and 6).
With the crate partially set up to this extent and temporarily braced against collapse by partition 57, the end flaps 41 on each side wall panel 40 are swung inwardly into aligned, endto end relation, in which position the shaped slots 44 in those flaps defining hand hole recesses at 45 and a vertical clearance space 46 therebeneath (Figs. 3 and 8). 'Overlapped end wall flaps 51 on bottom panels 49 are now swung upwardly 90, in which position their U-shaped openings 54, 55 come into register with the hand hole bays 44 of flap 41.
Outer end wallpanels "27 .are then swung 90 downwardly, causing their hand holes 38 to register with the other hand hole provisions described above, whereupon the various sets of flaps 41, 51 and panels 27 are secured together by wire staples or stitches 56.
It will be appreciatedth'at the slanting of bottom end flap creases 52 has the :effect'. of bringing the medial overlapped seam zone of the flaps 51 inwardly somewhat in relation to the outer free side edges of those flaps. Accordingly, when the outer end wall panel 27 is folded downwardly and secured in the position illustrated in Figs. 3 and 6, it is not strained or caused to bulge outwardly, to an undue extent. Outer surfaces of the end walls are truly perpendicular-throughout their area and a minimum tearing or bursting stress is imposed on the multiple stitched plies of the end walls in their assembled relation.
When the crate is in trated in Figs. 3, 7 and.
the condition described above, the small cut-scored lugs 36 on inner end wall flaps 18 are folded inwardly about their cut-score hinge 35, bringing the same into downwardly depending, face to the latter are swung downwardly 90 about their own hinges 19. So positioned, lugs 36 space the flaps 18 as shown in Fig. 6, and when the hand hole tab39 is flexed inwardly to manually grip and lift the'crate end, a very desirable, board-like beam is afforded for the purpose.
Damage to the contents of the crate in lifting the same as described and in. other respects, is prevented by a pair of separate cushioning andpartition bracing inserts, generally designated 58 and shown in Fig.4, one positioned on either side of cross partition 57 in the subdivided sections of the crate, as illustrated in Figs. 3 and 6.
Inserts 58, which are of width only slightly less than the distance between crate side walls 40, are constituted by rectangular sheets of the treated corrugated paperboard. They are sectioned transversely, in off center relation to the midpoint of the sheet, by a crease 60 extending from side to side thereof, thereby defining rectangular hinged panels 61, 62 of unequal area, which are intended to serve as false floor and end wall cushion mernbers, respectively. In successively positioning inserts 58in the crate the edge of the insert panel 61, which parallels crease 60, is first placed in edge abutting relation to the joint between a partition panel 16 and its appended friction flap 32, about which joint the flap 32 is outwardly buckled, as shown in Fig. 6. A downward pressure is now exerted on the panel 61, causing the insert to buckle downwardly about its transverse crease 60, as indicated an end wall structure.
As this inserting movement wall flap 18 is manually is continued the inner end restrained downwardly, holding its tongue 36 folded as described above, until the upper edge of panel 62 snaps outwardly beneath corner webs 24 and engages against that fla and with crease 60 frictionally nested into the bottom end angle of the crate. It will be observed that the flap 18 causes insert panel inwardly somewhat from the remainder structure, imparting an end cushioning effect to the panel which is very desirable. It will also be observed that the dimension of end wall cushion flap is such that its upper edge overlies flap 18, being substantially coplanar with the upper margin of downturned flap lug 36 and the internal margin of the flap on which the lug is hinged.
The same cushioning effect. is provided by false floor panel 61 of each insert 58. It is seen that the inserts not only lock partition panels 16 in proper upright position, spaced by the intervening, alternate and longitudicreases 60. This spaces the false floor above the crate bottom; cushioning the fruit or produce in each compartment. The inserts A cover panel, generally designated 65 and shown in Fig. is provided for use with the improved crate. This panel is fabricated from a corrugated board sheet 66 whose side to side width is slightly less than the distance between side wall panels 40. End flaps are designed on sheet 66 by transversely extending creases 68, extending between opposed V-shaped notches 69 in opposite side margins of the sheet. Creases68 are centrally interrupted by U-shaped slits 70 having their termini at the inner ends of the creases, thereby outlining projecting tongues71 on the sheet when flaps 67 are folded 180 about creases 68.
The length of the thus folded cover 65 approximately equals the distance between inturned inner flaps 18 of the crate end structure and its tongue 71 are received in openings 73 in each such fiap left by the downfolding of its cut-scored lug 36, being of about the the opening.
Cover 65 as applied to the crate appears as illustrated in Figs..6, 7, 8
lug openings 73 and have stable support from beneath, when required, by the flap, its lug 36 and the entire upper edge of insert panel 62. The center of the cover is flexed supporting attributes of a unit made of rigid material are same width as sidered especially as a compartmentized container, the crate is more essentially a load-supporting unit, and its provisions to this end are more important, than its provisions for internally subdividing the same. However, the compartmentizing provisions have been availed of in a novel manner in the improved crate as means also functioning to increase the rigidity and strength of the same.
The triangular Webs 23 which articulate cross partition structure 57 to side walls'40, coact with the top of that structure in preventing a continuous horizontal beam across the center of the crate, on which cover sustains crates above the same, and which transmits this load to a support through any other crates stacked thereabove. Being located on opposite sides of the cross partition, triangular webs 23 also exert a force-couple between the partition and side walls which has the effect of resisting torsional wracking of the crate about a vertical center axis, as under bumping or eccentric compression. Webs 23, 24 present six distinct points of vertical support, coupled with one another by cross partition 57 and by the end wall structures of the crate. These areas or zones transverse or longitudinal sense.
It is seen by reference to Fig. 7 that grapes or other and center, well above the side recesses 20, effectively held against dislodgement by the strut cover 65. End cusion panels 62 of inserts 58 protect the fruit 62, the lower margin of the slot 73 in which the tongue is received, and the upward surface of the downturned, cut-scored lug 36. In this connection, the character of the notching at 54 of the upturned bottom flap 51 on the right-hand side of the blank 10 (Fig. 1) is such as to provide a clearance for the tongue 71 which thus abuts outwardly against the other, outermost flap 51, as shown in Fig. 6. Engaged in this fashion, cover The height of the end walls and center partition above the side walls 40, approximates the vertical thickness of Wooden cross spacers for conventional shipping lugs, the same purpose, accordingly not only is equivalent orbetter ventilation provided than in the. wooden lugs, but this is without increasing the over-all height of a stack of containers of a given number. The improved crate will load in a refrigerated boxcar as well as or better than the type it is intended to supersede. So loaded, it afiords equal strength and rigidity as a load support, and better protection for its contents which are cushioned in a manner impossible to secure in any conventional crate.
