BOTTLE CARRIER WITH PARTITIONS Curtis M. Shanahan, Chagrin Falls, Ohio, assigrior to Container Corporation of America, Chicago, 111., a corporation of Delaware Application Why 12, 1952, Serial No. 287,233

7 Claims. (Cl. 220111) This invention pertains to carrier cartons, for bottles, cans and other articles and commodities, constructed from materials such as paperboard, strawboard and the like. More particularly the invention is concerned with the manufacture or construction of a simplified and exceptionally piece of fibrous sheet material that it is susceptible of receiving and securing a plurality of filled or loaded bottles, cans or the like and of safely and securely supporting such items not only under static conditions but especially while the carton with its load is being carried by a handle part integral therewith.

One of the principal objects of the invention is to provide a carton of the character and material specified that it may be formed as a single, integral piece or blank of the material, so cut, scored, folded and secured that it may be stacked, shipped and otherwise handled in a fiat or collapsed state and yet may quickly and easily be erected or set-up in final usable condition.

Another principal object is to provide a carrier carton wherein there are side, end and bottom walls, a combined partition and handle and one or more transverse partitions, all composed from a single integral blank or piece of material, the construction being such that the side and end walls are firmly and securely fastened to one another and to and through the bottom wall and partition structures to the handle, the bottom wall itself being of especially unique construction for strength and uniquely interengaged and interlocked with the handle, which also serves as a center partition, thereby to transmit theload directly and evenly to the handle for carrying purposes.

Still another important object is toprovide an easily effected interlocking arrangement whereby the several partition members and the bottom wall may be fastened securely against accidental release and the carton, as a whole, may be made relatively rigid as wellas strong and secure, once the carton has been set-up orerected'and made ready for use.

A further important feature of the invention resides in the provision of a novel construction of those partitions which extend transversely of the main or center partition and handle whereby extra bufier or cushioning effects between containers, such as. bottles, in adjacent compartments or cells, may be obtained,.the inclusion or omission of this feature being optional.

Other objects including a special arrangement of certain of the score or fold lines with respect to others and other features of the carton to facilitate folding and erection of the final product, will become apparent and understood after reading the following description and claims and viewing the accompanying drawings in which:

Fig. l is a plan view of a blank from which a preferred form of the inventionmay be produced, the view showing the scored lines for folding and the slits and slots and other openings all of which have function purpose in forming and utilizing the resultant product; and

Fig. 2 is a perspective view of the carton formed or erected from the blank of Fig. 1, portions of one end and one side wall having been broken away to reveal the internal appearance.

The blank shown in Fig. 1 may be considered to be of rectangular shape in general. One marginal edge 3 which is straight is to become the upper marginal edge bounding each of the side walls to be formed by side wall panels 4 and 6, each of the end walls to be formed by end Wall panels 5 and 7,,and the glue flap 8. Lines of scoring, for folding each of the side and end wall strong carton so made from a single integral Patent 0 Patented Nov. 16, 1954 panels into box form of rectangular shape are designated 9, 10, 11 and 12, extend perpendicular to the edge 3 and parallel to one another from the edge 3 to a score line 13 which extends from one end edge 14 of the blank to its other end edge 15 in parallel relationto the edge 3, the edges 14 and 15 being parallel to lines 9, 10, etc. The score line 13 defines thebottom edge of each of the side and end walls in the carton when completed and the distance between edge 3 and score line 13 determines the height of each side and end wall. The distance between edge 14 and score line 9, the same as that between score lines 10 and 11, determines the carton length along its side walls and, similarly, the distance between score lines 9- and 10, which is equal to the distance between score lines 11 and 12, determines the carton width along its end walls.

Attached to wall panels 4, 5, 6 and 7 at the score line 13 are bottom wall forming panels 16, 17, 18 and'19; respectively, of which panels 16 and 18 are to become the inner or lapped panels of the bottom wall while panels 17 and 19 are to become the outer or lapping panels of the bottom wall when the carton is completed in its erected or set-up state. Connected to the panels 16 and 18 along aligned score lines 20, 22 which are parallel to score line 13, are center partition and handle forming panels 24 and 26, respectively, while connected to panels 17 and 19, along score lines 21 and 23, respectively are transverse partition forming panels 25 and 27; The panels 24 and 26 are similar to one another in size and shape as are'panels 25 and 27 to each other but, as will be seen in Fig. 1, while score line 20 is aligned with score line 22 and 21 is aligned with 23, the latter two score lines are off-set to a greater distance from score line 13 than score lines 20 and 22 for a purpose to be described. Slits 28, 29 and 30, extending from score line 13 outwardly, separate and define the side edges of the several panels 16 and 24 from panels 17 and 25, the latter from panels 18 and 26 and the last from panels 19 and 27, respectively. The slits 28, 29 and 30 are aligned with score lines 9, 10 and 11, respectively.

Each of the transverse partition forming, panels 25 and 27 includes an auxiliary or supplementary partition forming panel 25 and 27', respectively, connected'thereto along the aligned score lines respectively designated length of each of panels 25 and 27 from a score line- 25" to the opposite and parallel free edge is somewhat less than the dimension of either of panels 25 and 27- from the score line 25" to the score line 21 or 23, as the case may be but in no case should this dimension of the panels 25, 27 be greater than the corresponding dimension of panels 25, 27.

Extending to equal distances from score line 20 into the adjacent panels 16 and 24, are a pair of slots generally designated 32, 34. One portion of each of these slots extends completely across the panel 16 from score line 20 to score line 13 and is substantially symmetrical in:

shape and size with respect to the other portion extending into panel 24, the latter portion, however, being someto the other or, the mirror image of the other, as Fig. 1 reveals. The edge defining that boundary of each of slots 32 and 34 which lies closest to the edge 14 or that edge formed by slit 28, as the case may be, has a curved center portion 36 merging with alignedtangential portions 38'at its ends, while the opposite defining edge has aligned tangential end portions 40 parallel to the tangential portions 38 and an outwardly offset curved portion 42 connected to tangents 40 by portions 42', 42" between portions 40 to provide a pair of projections 44 delineated from one another by the score linev 20 extending between them.

Preferably the minimum transverse width of each slot is somewhat greater than the thickness of the sheet material of which the carton'is composed. Since the carrier carton is tohave three compartments or cells for bottles or other items on each side of the center partition, each of the slots 32, 34 is located substantially one third of the distance from the adjacent edge 14 or that formed by slit 28, as the case may be, and preferably so that the aligned tangential portions 40 of each slot extend parallel to the edge 14 and that formed by slit 28 at a distance one third of that from one of such edges to the other. The slots 32' and 34 in panels 18 and 26 are similar in every respect to slots 32 and 34, the slot 32 being complementary to slot 32 and slot 34' being complementary to slot 34, as will appear more clearly as this description proceeds.

The outer end marginal edge 46 of one and 46' of the other of the two center partition panels 24 and 26, when the carrier carton is finally erected, will project well above the side and end walls to provide an easily accessible handle by which the carton and its contents may be carried. In order to provide for gripping by the hand of the user, the center partition panels 24, 26, at conveniently spaced registerable places adjacent to their upper edges, are provided with the usual finger push-outs 48 each being of generally rectangular shape with three sides out free from the panel and the fourth side hinged along a score line 50.

Centrally of what will be the bottom edge portion of the transverse partition forming panel 25, is an opening of triangular shape defined by edges 31, 31 and 33, and a similar opening defined by edges 31, 31' and 33 is formed in panel 27. The edges 31, 31 are of equal length and the apex angle formed by their junction is bisected by a line perpendicular to the edge 33 at its mid point and running medially of the panels 25, 25' with respect to their side edges, such mid point also being the mid point of the base of panel 25 formed by the score line 21 and the edge 33 extending in alignment with the parts thereof. Edge 33 is of a length equal to or slightly greater than the distance between the edge portions 42, 42" defining the side edges of the adjacent and connected projections 44, 44 when extended as shown in Fig. 1, while the perpendicular distance from the mid point of the edge 33 to the apex of the angle or juncture of side edges 31, 31 is equal to or slightly greater than one half of the length of edge 33 or equal to or slightly greater than one half of the distance between edges 42', 42", measured as before. Of course, if desired, a T-shaped slit or slot the head of which is positioned and of the same length as edge 33 and the stem of which is equal to the perpendicular distance from edge 33 to the junction of edges 31, 31, may be substituted for the full opening, as will be apparent. The corresponding opening in panel 27 as defined by edges 31, 31 and 33' panel 25.

Symmetrical with respect to the common median line of panels 25, 25' and also symmetrical with respect to the fold or score line 25" between these two panels is another slot defined in part by parallel edges 35 in panel 25, in part by parallel edges 35' in panel 25' and in part by the edges 37 and 37, respectively of the panels 25 and 25, diverging from the respectively parallel edges 35, 35 to their junctions at the fold or score line 25". The width of the narrow part of each end of such slot preferably is double or slightly greater than double the thickness of the material of which the carton is composed as such slot parts will receive a portion of each of the two center partition forming panels as will more clearly appear hereinafter. The length or depth of the slot in panel 25, that is, the location of the inner end thereof from the fold or score line 25", is determined by the perpendicular dis tance from fold or score line 21 to score line 25" and the correspondingly measured distance from the fold line 20 between panels 16 and 24 to the terminus of slot 34, within panel 24. In other words, the slot in panel 25 will have its blind or inner end terminated at such distance from score or fold line 21 as may be equal to or less than (but not greater than) the perpendicular distance to the terminus of either of the slots 34, 34 from the either of the respectively adjacent score or fold lines 20, 22, the length of the slot within the panel 25 being determined by the distance from the blind end of such slot from the fold line 25", the depth of the other half of such slot within panel 25' being the same. The corresponding panels 27, 27' are also provided with a corresponding slot which, since it corresponds in shape size and location with the slot in panels 25, 25', need not be described further.

After the blank of Fig. 1 has been cut and scored in the manner described, glue or other adhesive is appliedis similar in every respect to the opening in K over that face of glue flap 8 which is the dress or finished side or surface of the sheet and the flap is secured to that face of the side wall panel 4 which is its unfinished or opposite surface. If it be assumed that the blank of Fig. 1 has its finished surface facing away from the observer, adhesive will be applied over that surface of flap 8 which is also facing away from the observer. Although the application of adhesive and the various folding steps may be performed in any order of several, for the purposes of this description only one sequence, which may or may not be preferred depending upon machinery employed and other factors will be described.

Each of the panels 24 and 26 may be swung upwardly about its respective fold line 20 or 22 and over and down in face to face relation with panels 16 and 4 and panels 18 and 6, respectively. Also each of panels 25 and 27 with their respectively attached panels 25 and 27 will be swung upwardly about its respective fold line 21 or 23 and over and down in face to face relation with panels 17 and 5 and 19 and 7, respectively. Next the thus folded panels 4, 16 and 24 may be folded as one upward, over to the right and down about fold or score line 9 to lie upon panels 5, 6, 17, 18, 25, 25' and 26 which have been folded as above described. Thereafter the panels 7, 19, 27 and 27 as previously folded, together with the glue flap 8, are folded as one upwardly, over to the left and down about the score or fold line 11 to lie upon the previously folded panels 6, 18 and 26 and the glue flap 8 may be tucked under the adjacent marginal edge of side wall panel 4 and secured thereto.

In its thus folded condition the carrier carton lies fiat, and may be bundled in quantities, and so packaged, stored, shipped and otherwise handled. When a carton is to be erected or set-up for use, the operations to do so are simple indeed. First, by pressure applied from opposite directions against opposite ends of the fiat carton, i. e. against fold lines 9 and 11, the carton will be caused to expand to a generally rectangular tube whereupon the panels 25, 25 and 27, 27 may be unfolded or drawn out of the bottom of the tube. Then the center partition panels will be brought together in back-to-back contact and registration as those panels appear in Fig. 2, the attached bottom wall panels 16 and 18 being swung about the fold lines 13 and 20, 22, respectively, to positions where their planes are at right angles to the planes of the side walls 4 and 6 and to the planes of the center partition panels 24 and 26. At this time those halves of each of slots 32, 34, 32, 34 in panels 24 and 26 will extend vertically and at right angles to the other halves in the bottom panels 16 and 18, and one half of each projection 44-44 will lie in the horizontal plane of a bottom panel 16 or 18 while the other half of each such projection will lie in the vertical plane of that center partition panel with which it is connected. With the center partitions and bottom wall panels 16 and 18 so positioned and related the halves of slots 32 and 34 which extend into the panel 24 will mate or register with the respectively corresponding halves of slots 32' and 34' which extend into panel 26. Similarly, the remaining halves of the same slots which extend into panels 16 and 18 will be brought into end to end abutting register.

The next step is to fold each of the auxiliary or supplemental transverse panels 25' and 27 about their respective score lines 24" into face to face relation with respect to the adjacent panels 25 and 27. While this folding may be in either direction, that is, to swing the panels 25, 27 against either face of the respectively adjacent panels, it may be preferable so to make these folds that, in the finally erected carton the panels 25 and 27' will lie between the respective panels 25 and 27 and the respectively adjacent end wall panels 5 and 7 after the manner indicated in Fig. 2. Following the foregoing operations the folded edge (fold line 25") between either panels 25, 25 or 27, 27 is passed into the adjacent slot formed by the abutting registration of the halves of slots 32, 32 or 34, 34' and pushed upwardly therein until the registered blind ends of the slot 3537 abuts the registered blind ends of the slot halves in the center partition panels 24, 26. The procedure is repeated for the other transverse partition panels.

As the folded edge of a pair of transverse partition panels is entered in the bottom panel slots it may be bowed slightly to clear the abutting halves of mating or registered projections 44.. When the partition panels are disposed at their uppermost positions the projections 44 will enter the triangular openings in those panels and pass through them in uhich position the upwardly directed side edges 42 will be in or substantially in edge engagement with the apex edge of the triangular opening in the main panel of the transverse partition as clearly shown in Fig. 2. At this same time the edges 42. of the adjacent registering projections Will be in similar edge to edge or abutting engagement (or near engagement) with the edges of the main transverse panel at apices of the angles formed by edges 31 and 33, and the under or downward facing surfaces of the horizontal parts of projections 44 will overly and be in face to face contact (or near contact) with the upper or inside surface of the adjacent bottom panel 17 or 19, as the case may be. The resulting appearance is shown in Fig. 2.

Thus folded and erected or set-up, the carrier carton is strong and rugged and firmly and securely supports its contents individually and collectively. The side Walls are integral with the end walls offering mutual support to one another and the end walls abut against the adjacent end edges of the double-ply center partition finding support thereagainst. In the instant form approximately two-thirds of the bottom wall, upon which the load is to fall directly, is composed of two plies or thicknesses of the material of which one ply (the inner one) is composed of the two panels 16 and 18 each integrally joined to one of the side walls along its bottom edge, and of which the other (the outer ply) is composed of the two panels 17 and 19 similarly connected with the end walls. Those bottom wall panels, inI turn, being integral with the center partition panels and with. the transverse panels and being interlocked with one another against material lateral, longitudinal and vertical movements relative to one another by reason of the construction illustrated and described, provide an unusually rigid structure as will be appreciated. The interlock between the transverse and center partition panels with the projections 44 of the bottom panels 16 and 13 overlying and finding support from the bottom panels 17 and 19, lends support and strength to the bottom wall of each center compartment or article receiving cell so that those center cells, in eifect, have a two-ply strength to a substantial degree.

The oiI- set score lines 21 and 23 increase the width of panels 17 and 19 to compensate for the fact that those panels overlap (under lap) parts of the panels 16 and 18 and thereby permit the transverse partition panels 25 and 27 to extend vertically and at right angles to the general plane of the bottom Wall. The construction therefore facilitates insertion of the panels 25, 25' and 27, 27' through the slots in panels 16, 18 and upwardly to their final positions and aids in insuring that the interlock between the partitions is properly effected and will not accidentally be released. In a carton having side Walls measuring 7% inches each and end walls measuring 5 inches each, an off-set of each of score lines 21 and 23 from score lines 20, 22 in the amount of of an inch has been found to be quite satisfactory using material of a thickness of approximately of an inch.

The auxiliary panels 25, 27' may be omitted but when included provide an excellent cushioning means between articles, such as bottles, packaged in the compartments or cells of the carton, thereby preventing or minimizing the possibility of breakage due to impact of one article against another through a single wall thickness. These auxiliary panels may also aid to an extent in maintaining a firm interrelationship between the center and transverse partitions. If desired the auxiliary panels may extend further toward the bottom wall or be of greater width or both and other changes or modifications may be made therein. The push-out tabs 48 may remain in the planes of the respective center partition panels until the carton and its load are to be picked up for carrying, after the usual manner.
