MULTICOMPARTMENT SHIPPING CARTON Filed June 19, 1951 2 Sheets-Sheet 2 I N V EN TOR. Alexander L. G/roqx. Sa/rafare A. Aqumo United States Patent MULTICOMPARTMENT SHIPPING CARTON Alexander L. Giroux, Jersey City, and Salvatore A. Aquino, Teaneck, N. J., assignors to The Hinde & Dfagfllii Paper Company, Sandusky, Ohio, a corporation 0 o Application June 19, 1951, Serial No. 232,404

4 Claims. (Cl. 229-28) This invention relates to multicompartment shipping cartons and is a continuation-in-part of our copending application Serial No. 143,644, filed February 11, 1950. The invention has for its object to provide .a knockdown multicompaitment carton that has great rigidity and strength when assembled.

In packaging fragile articles such as goblets, cups, vases and the like for shipment, it has been the usual practice to carefully pack the individual articles in a shipping container of rigid construction, the articles being so packed that they are held .against relative movement in the container and the container being of a strong and rigid construction so that the articles will not be sub ected to compression due to distortion of the container by weight imposed thereon. l he alternatives, high cost of shipment and high percentage of loss due to breakage, have resulted in retail prices so high as to greatly impede the sale of such articles.

The present invention has for an object to provide a knockdown multicompartment carton of paperboard or the like which is of simple and inexpensive construction, which can be shipped and stored in knockdown form, which is easy to assemble, and which has the strength and rigidity necessary for the protection of fragile articles against breakage.

'lhe carton or the present invention has a collapsible body of rectangular form and a combined closure wall and partition structure in which the partitions are formed integrally with the closure walls and interlock to provide a crisscross system of upright partitions within the body which not only stifien the end wall structure, but also internally brace the collapsible body portion of the carton.

Reference should be had to the accompanying drawings forming a part of this specification, in which:

Figure 1 is a plan View of a paperboard blank from which the multicompartment carton embodying the invention can be formed;

Fig. 2 is an isometric view of the carton formed from the blank shown in Fig. 1;

Fig. 3 is a vertical longitudinal section through the carton taken onthe line indicated at 3-3 in Fig. 2;

Fig. 4 is a vertical transverse section through the carton taken on the line indicated at 4-4 in Fig. 2;

Fig. 5 is a plan view of a blank from which a modified form of carton embodying the invention may be formed;

Fig. 6 is an isometric view of a carton formed from the blank shown in Fig. 5;

Fig. 7 is a vertical section through the carton taken on the line indicated at 77 in Fig. 6; and

Fig. 8 is a vertical section through the carton taken on the line indicated at 8-8 in Fig. 6.

In Fig. 1 of the drawings there is shown a paperboard blank having a central portion from which the collapsible body of the carton is formed. An end wall 1 is hinged to a side wall 2 by means of a transverse fold line 3. A second end wall 4 is hinged to the side wall 2 by means of a fold line 5 and a second side wall 6 is hinged to the end wall 4 by means of a fold line 7.

The walls 1, 2, 4 and 6 form the collapsible body of the carton which is rectangular in shape, the fold lines 3, 5 and 7 being at three of the vertical corners of the body. An end of the side wall 6 is attached to an end of the end wall 1 by suitable means such as a strip of tape 8 glued to the walls which forms a fourth hinged connection between the upright walls of the body so that the body may be-collapsed for shipment.

I 2,693,309 Patented Nov. 2, 1954 A pair of flaps 9 are hinged to the bottom edges of the side walls 2 and 6 by means of fold lines 10, and a second pair of flaps 11 are hinged to the walls 1 and 4 by means of fold lines 12. The flaps 9 and 11 provide a combined bottom wall and partition structure for the carton, each of these flaps having portions that are disposed horizontally to form the bottom wall of the carton, and portions which are disposed in upright position to form crossing partitions when the carton is assembled. Each of the flaps 9 has a bottom wall portion 13 and a partition portion 14 which is hinged to the wallportion 13 to swing about a fold line 15 that extends transversely across the flap parallel to the fold line 10 along which the flap is joined to the bottom edge of the side wall.

Each of the flaps 11 has a bottom wall portion 16 and a partition portion 17 that is hinged to the wall 16 along a fold line 18 that extends transversely across the flap parallel to the fold line 12. The partitions are preferably of the. same height as the carton walls and in order to facilitate assembly of a carton having relatively high partitions, the partition portions 17 of the flaps 11 may be made bendable by means of a fold line 19 extending across the same parallel to the fold line 18. The flaps 9 are provided with slots 20 to receive the partition portions 17 of the flaps 11. The slots 20 extend from the fold lines 10 at right angles thereto across the bottom wall portions 13 of the flaps and partially across the partition portions 14 thereof. The slots 20 of the two flaps 9 are transversely alined when the flaps are folded inwardly to position the bottom portions 13 thereof horizontally between the side walls 2 and 6.

In assembling the carton the flaps 9 are first folded between the side walls 2 and 6 to dispose their bottom wall portions horizontally and their partition portions upright. The flaps 11 are then folded inwardly to position the wall portions 16 thereof beneath the wall portions 13 of the flaps 9, and the partition portions 17 of the flaps 11 are then inserted into the slots 20. The wall portions 16'of the flaps 11 are of a length to extend lengthwise of the Wall portions 13 of the flaps 9 from the end wall to the slots 20, and the slots 20 are of a width to receive the partition portions 17 of the flaps 11 back to back. In the carton shown in Fig. l, the slots 20 are centrally disposed so that the partition portions 17 of the flaps 11 form a transverse partition of double thickness between the walls 2 and 6 midway between the ends thereof. In order to provide three rows of compartments, the width of the bottom portion 13 of each of the flaps 9 is substantially one-third the width of the carton so that the partition portions 14 form longitudinal upright partitions parallel to each other and to the side walls of the carton and spaced equally from one another and from the side walls.

In order to provide an interlock between the partition portions 14 and 17, the partition portions 17 are provided with notches 21 spaced apart'a distance corresponding to the spacing of the partition portions 14 so that when the partition portions 17 are inserted into the slots 20 of the flaps 9 the notches 21 will receive the portions of the partitions 14 between the upper end of the slots 20 and the top edges of the partitions, thus forming a rigid interlock between the crossing partitions.

The notches 21 may be provided with flared entrance portions 22 to facilitate assembly.

In the twelve compartment carton shown in Figs. 1 to 4 the wall portions 16 of the flaps 11 are of a width twice that of the wall portions 13 of the flaps 9 and the partition members 14 and 17 provide compartments on opposite sides of the double thickness partition formed by the partition members 17 which are twice as long as they are wide, so that by insertion of an intermediate partition between the central partition and the end wall 6, square compartments can be formed on each side of the central partition.

In order to increase the rigidity of the carton the additional partitions are preferably part of a top closure structure, being formed by portions of flaps 23 that are hinged to the top edges of the end walls 1 and 4. Each flap 23 has a wall portion 24 of a width corresponding to the wall portions 13 of the flaps 9 and, hinged to the 3 a wall portion 24,"-thereis a partition portion 25 that is hinged to the wall portion 24' along" a'fold line26 extending across the flap. -To facilitate assembly the partition portion 25 may be made bendable by means of a 1 fold line 27'parallel to the" fold line 26.

The partition portions 14 are"provided-'withspaced notches 28 to receive the partition portions'25- of the top flaps 23 and the-partition portions 25 are provided with collapsiblebody-of the carton is rigidlybracediby means of the interlocking partition structure in which the individual partitions are disposed at night angles to'the v upright 'walls and abut the same intermediate the .;ends

thereof. The rigidity of the carton is also greatly increased by 'the overlapping .wall:port ions"13; and; .16 of the flaps, together with the wall portions'24 of the top 'fiaps' 23 which provide arigid brace between the side walls at the ends-th ereof.

' jThe cartonmay be provided 'with a cover formed by -flaps 32 hinged by fold lines 33 to,the top edges of the side walls 2 and 6. Each of the flaps 32 is of a width corresponding to one-half thewidth of the carton so that the two flaps can abut edge to, edge along the longitudinal center line. Since theportions' 24 of'the top partitionflaps rests. upon the top edge of the partitions 14, theflaps32 are preferably providedpwith central tabs 34 connected 'thereto bylold lines 35, the

tabs 34 being of a length'to bridge the spacebetween the partition membersZS sojthat byf-folding the taps inwardly against the inner faces of the cover, flaps 32 the tabs 34 will rest upon -vthe top edges of the partitions-17 and extend across'the,rspacezbetweengthe. partitions 25, thus additionally stifieninglhezrtop Of ,the

tom flaps 61 and 68 receiving the portion of the bottomv flap 39 above its slot-59 and the portion of 'the top flap 44 above its notch 66. In a like manner the partition portions 83 and 86 of the topflaps'67 and 68 are received in the slots 61 and 62 of the top flaps 43 and 44 and in the notches 63 and 64 of the bottom flaps 39 and 40, the notches 87 of the top flaps 77 and 78 receiving the portion of the top flap 43 below its slot 61 and the por tion of the bottom flap 40 below its notch 64, the registering notches 88 of the top flaps 77 and 78 receiving the portion of the top flap 44 below its slot 62 and the portion of the bottom flap 39 below its notch 49.

The flaps 39, 40, 43 and 44 form a central transverse partition of double thickness and two transverse partitions of single thickness midway between the central partition and each end wall as shown in Fig. 7, and the flaps 67, 68, 77 and 78 form two longitudinal partitions of double thickness as shown in Fig. 8 and all partitions are firmly interlocked at their intersections by their slots and notches.

All of the partition members are preferably of substantially the same height as the carton walls 36 and 37 and, in order to facilitate the assembly of the carton, the side wall flaps 67 and 68 and 77 and 78 are preferably provided with transverse fold lines 89 across their partition portions, the fold lines 89 serving to facilitate the insertion of the partition portions 73, 76, 83 and 86 into the slots 59, 60, 61 and 62 and the alined notches 63, 64, 65 and 66.

The flaps 39, 48, 43 and 44 provide an inner partition and bracing structurewhile the flaps 67, 68, 77 and 78 are the main closure flaps which also serve to complete the partition structure.

By reason of the fact that the partition portions of the closure flaps 67, 68, 77 and 78 are'relatively long and confined back to back in the slots and notches of the partition portions of the flaps 39, 40, 43 and 44 and by reason of the fact that the partition portions are connected to the walls of the carton by relatively narrow wall portions, a considerable pull on the flaps is required to open them and the carton when once assembled is securely held closed by frictional engagement of partition portions 67, 68, 77 and 78 with one another and in the slots and notches of the other flaps so that it is unnecessary to employ tape to secure the closure flaps in closed position.

The double thickness partitions extending longitudinally and transversely of the carton also serve to give the carton great strength and rigidity and efiectively protect fragile articles that are packed in the container compartments.

It is to be understood that in accordance with the provisions of the patent statutes, variations and modifications of the specific devices herein shown and described may be made without departing from the spirit of the invention.
