No. 258,439 17 Claims. (Cl. 229-428) This invention relates to improvements in a collapsible multiple cell carton and more particularly to a collapsible carton which may be formed from a unitary blank and is adaptable to embodiment in cartons having varying numbers of cells, as for example 6 cell or 12 cell.
Collapsible cartons having dividers or partitions there in are commonly used for carrying bottles and are used in large quantities, generally on high speed production lines. Therefore, they must be of simple construction so that they may be manufactured readily on ordinary equipment and from the standpoint of the user they must be subject to easy erection and loading. The present carton fills these requirements in an advantageous manner.
It is an object of the invention to provide a multiple cell carton which may be readily formed from a unitary blank by the simple folding of the sheet material in one direction, in respect to the plane of the blank, Without the necessity of resorting to complicated reverse folds or special manipulation of the parts to attain locking engagement or assembly of the carton. It is a further object of the invention to provide a collapsed container with integral dividers that may be readily erected to rectangular formation by the mere exertion of pressure on the outer corner folds of the collapsed carton by which means the walls are erected to tubular relation and the bottom closure and integral dividers are automatically formed into operating relation to the carton walls.
Still another object of the invention is to provide a carton of the described character which may be readily collapsed from the open rectangular formation and reereoted at will by the mere exertion of pressure on diagonally opposite corner folds of the carton. These and other objects of the invention relating to details and economies will appear from the following description taken in conjunction with the accompanying drawings, in which:

FIGURE 11 is a fragmentary perspective view of the carton showing the dividers in the carton including the hlddddli Patented May 18, 1965 further modification from the blank shown in FIG- URE 10.
The blank 2% shown in FIGURE 1, viewed from the outer surface thereof, is suitably cut and scored, as indicated by solid lines and dotted lines respectively, to form a carton with integral internal dividers to divide the carton into a 6 cell arrangement. The blank described in terms applicable to the set-up carton includes side wall panels 21 and 22 and end Wall panels 23 and 24. The wall panels are foldably connected b corner scores 25. End Wall panel 24 includes a free side edge 26 and side wall panel 231 has a side edge determined by the fold connection 27 of the connecting flap 28,
The top edge of the wall panels Zl-Zd is determined by a flap score 29 which serves as the hinge connection of the top closure flaps 3! A handhole 31 may be provided as shown in end wall 24- with a hinged tab 32 which is connected to the end panel 24 by the score 33.
The bottom closure flaps 34 are hingedly connected to the bottom edge of the wall panels 21-24 by the flap score 35. The bottom closure flaps 34 include end flaps 36 and 3'7 connected respectively to the end walls 23 and 24. Also included are side flaps 3839 which are connected to the side walls 2142 respectively. Slots 49 separate the respective pairs of bottom flaps 38-36 and 39-37. The slots ii are determined b the side edges 41 which diverge downwardly and outwardly from the junction of the corner scores with the flap score 35. The opposed side edges of the end flaps 3637 are determined by edge 42 which is substantially in alignment with the respective side edges of the associated wall panels 23-24 or offset therefrom in a conventional manner. Said end flaps 3t37 are further provided with angular fold lines 43 disposed at substantially 45 an le to the flap score and intersecting said flap score substantially at the juncture with the corner scores 25. The side flaps 3$39 include angular free side edges 44 disposed at substantially 45 angular relation to the flap score 35 and intersecting said flap score at the juncture with the respective edges 27-25 of the associated side Wall panels 21-22.
The divider assembly 5-5 is foldably connected to the inner end edges of the closure flaps 34 along aligned fold lines 47 and includes longitudinal and transverse divider members which are associated with each of the bottom flaps 36-39 A first divider portion 46 is foldably connected to the end flap 37 by the fold line 47 and is comprised of an end longitudinal member 43, transverse divider member 5-5 and connecting tab St? in foldably connected relation. The transverse member 49 is further provided with a lateral tab 5i struck from the end longitudinal member 48.
A second divider portion 52 is hingedly connected to side flap 33 by fold line d7 and is comprised of a transverse member 53, intermediate longitudinal member 54 and transverse member 55. The transverse member 55 is provided with a lateral tab 56 struck from the intermediate longitudinal member 54.
The divider assembly portions connected to the remaining bottom flaps 3t? and 39' are similar to the beforedescribed portions associated with their counterpart side and end tlaps 37 and 38. Thus, there is associated with the end bottom flap as a divider portion comprising an end longitudinal member id and transverse member 49 and lateral tab 51. The divider portion connected to the side flap 39 is comprised of a transverse member 53, intermediate longitudinal member 54 and transverse member 55 in toldably connected relation. The transverse member 55 is provided with a lateral tab $7. The latter two divider portions, associated with the pair of end and side walls 23 and 22 are in foldabiy connected relation by a score line which is an extension of the score 2.5.
After the container blank in FIGURE 1 is cut and scored as described above, the first folding operation shown in FIGURE 2 requires the folding of the bottom closure flaps 36-39 and associated divider assembly 45 about the flap score 35 into flatwise relation to the inner surface of the wall panels 21-24. Adhesive areas as denoted by the stipuled areas are applied'to the closure flaps and divider assembly. More particularly the adhesive is applied to the triangular portions 53 of the end flaps 36-37, the lateral tabs 51, 5d and 57, and the connecting tab 50. It is to be noted that the stipuled areas are extended to include the surfaces that will be in face contacting relation with the adhesive coated areas and it is obvious that the adhesive may be applied to either one or both of the surfaces that are adhesivel bonded together.
Continuing the assembly operation, as the-side wal panel 21 is folded about the corner score 25 and the end wall panel 24 is folded about its corner score 25, the before described adhesive coated areas are brought into Wall corner face contact and bonded to provide a container in collapsed condition as shown in FIGURE 3, with the connecting flap 28 adhesively or otherwise secured to the subjacent marginal edge 26 of the end wall 25. In this condition, the container may be stored or shipped to the final user and is ready for automatic assembly to the erected condition by the mere exertion of pressure on the remote edges 59.
I As shown in FIGURE 4, the erected container formed from the unitary blank 20 when erected to article receiving condition includes an automatically erecting and locking bottom closure 34 and divider assembly 45. Looking at FIGURE 4 in connection with FIGURES 5, 6 and 7, we see that the divider assembly is comprised of two sections in foldable slidable relation which are connected at the transverse dividers by the overlapping lateral tabs 51, 56, 57. Each such section is comprised in this 6 cell embodiment of the invention of a single ply end longitudinal member 48, a double ply transverse member 49 and 53, an intermediate longitudinal member 54 and a single ply transverse member 55. Further, each section is associated with an adjacent pair of side and end walls, more specifically 22-23 and 21 and 24. It is characteristic of these members that the intermediate longitudinal members 54 are in slidable, separable relation and the end longitudinal members 48 are foldably connected through the triangular portions of the bottom end flaps 36-37 to the end flaps and by the adhesive securement of these triangular portions to the sideflaps whereby upon the erection of the container the longitudinal divider members 48 are brought into disposition medially of the width of the container and adjacent the end walls'thereof. It is also to be noted, as best shown in FIGURE 5, that the single ply transverse dividers 55 are limited in their lateral extension whereby the outer edges thereof are in spaced relation to the respective side walls 21-22 of the container so that slidable passage of the end edges 60 and the inner surface of the sidewalls 21-22 is possible during the collapsing or erection of the container. It is also characteristic of the invention that each of the sections of the divider assembly 45 as for example the first and second divider portions which comprise one section are associated with a pair of adjacent side and end walls 21-24 and the other section comprised of divider portions dependent from the bottom closure flaps 36-39 and the paired side and end walls 22-23. This arrangement of the sections is apparent in cross sectional view in FIGURE 7 wherein the side by side foldably connected relation of the members comprising each section is shown.
FIGURES 8 and 9 show an embodiment of the invention in a 12 cell carton wherein the cell arrangement includes two rows of 6 cells each running longitudinally carton.
of thecarton. Referring more particularly to FIGURE 8, it may be seen that the carton is similar to the previ- V ously described embodiment of the invention including top flaps 61, side and end wall panels 62 and bottom closure flaps 63. The divider assembly 64 is modified, however, and will be described in detail. In the embodiment shown the intermediate longitudinal member 65 of each section is extended in length to equal four cells in longitudinal dimension. The intermediate longitudinal member is provided with diagonally arranged slots 65 which are terminated in spaced relation to the bottom edge $7 and top edge 68.
The slots 66 determine therebetween intermediate trans. verse divider members 69. The intermediate divider members 69 are terminated at their inner edge by score lines 7% which serve as a hinge connection to the intermediate longitudinal members 65. At their outer ends, the intermediate transverse divider members 69 are terminated in score lines 71 which serve as a hinge connection to outer longitudinal connecting members 72'. The outer longitudinal connecting members 72 are defined more particularly by the top edges 68 of the divider assembly 64, the beforementioned score line 71 and diagonal slotsdd and at the end extremities thereof by the free edge 73 and score line 72%. This latter score line 74 serves as a hinge connection to intermediate transverse divider member 75.
It is to be noted that the transverse member 76, is modified in comparison to the first described embodiment of the invention, to adapt the invention to a 12 cell carton, by the horizontal slot 77 which divides the transverse member 76 from the end portions of the outer longitudinal member 72.
The first divider portion 78 is identical to the first described embodiment, FIGURES 1 through 7, except that the connecting tab 7? is modified by a horizontal dividing slot 8% so that the lower portion 81 may be connected to the transverse member 76 and the upper portion 82 is connected to the free edge portion 73 of the outer longitudinal connecting member 72. As in the first described embodiment the first and second divider port-ions, 78 and 95 respectively, are connected together to form one section of the divider assembly 64. The second section 83 is identical in construction except that, of course, the portions thereof are integrally connected as best shown in FIGURE 8 and the connecting tab 79 is not required.
Looking more particularly to FIGURE -9, we can see that the outer longitudinal connecting members 72 of' each section of the divider assembly are disposed adjacent and in slidable relation to the side Wall panels of the The intermediate transverse divider members 69 and extend between the outer longitudinal connect ing member 72 and the intermediate longitudinal member 65 on each side to divide the intermediate portions of the carton into the required cellular compartments,
A further embodiment of the invention shown in FIG- URES 10 and 11 is similar to that shown in the beforedescribed FIGURES 8 and 9, having side and end wall panels 83 and 84 respectively, top flaps 85 and bottom flaps 86. The divider assembly 87 in this embodiment is similar to that disclosed in FIGURES 8 and 9 except that it includes an erecting tab 88 struck from the transverse member 75 and adjacent portions of the outer Ion-- gitudinal connecting member 72 of each divider as sembly section. v
The erecting tab 88 is defined by a cut line 89 in spaced relation to the diagonal slot '66 and includes a securing tab 9% defined by the generally L-shaped out line 91 in the outer longitudinal connecting member 72. The erecting tab 88 is hingedly connected to the intermediate longitudinal member 92 by the score line 93. Each of' the securing tabs are adhesively connected to the opposed divider assembly section outer longitudinal connecting member 94 when the carton .is erected in the manner as described in relation toFIGURES 2 and 3 of the first embodiment of'the invention.
It will be seen in FIGURE 11 that the erecting tab 88 provides a connection between the intermediate longitudinal member 92 of one divider assembly section and the opposed divider assembly section outer longitudinal connecting member 94. It will be noted that the erecting tab 88 is disposed in vertical alignment with one intermediate transverse divider member 95 and thus corresponds to the desired cellular arrangement in the erected carton.
Panticular embodiments of the invention involving 6 and 12 cell arrangements have been described but it is apparent that other modified forms are possible and in particular that the succession of side end Wall panels of the carton may be reversed while practicing the novel construction of the bottom closure and integral dividers assembly of the present invention.
