SHEET 0F 9 I V 5 5 2 1/ g E I FIGG PATENTED JUL 2 3 I974 SHEET E OF 9 PATENTED JUL 2 3 I974 SHEET 8 OF 9 FIG [2 CARTONS This invention relates to cartons, and more particularly to the type of carton provided with an interior divider assembly defining partitions and an extensible carrying handle. Such cartons are well known and are generally formed from three separate blanks i.e.

a. that required for the outer shell of the carton,

b. that required for the divider assembly, and

c. that required for the handle member.

During converting operations, several distinct machine procedures are involved. First the blank, ultimately forming the handle member, is stampled out by a die-cutting machine and is then passed to a machine which glues and folds it. Secondly, the blank, ultimately forming the divider structure, is stamped out by a diecutting machine and then passes to a gluing machine where, during its path of travel, it is spot glued and the handle member married thereto, the divider blank thereafter being folded so as to contain the handle within it. Finally, the combined handle and divider element is married to the outer shell of the carton which is then folded and glued so that the finished product is a knocked-down carton.

Accordingly, it is one object of the invention to provide a one-piece blank capable of being folded so as to produce a divider element with a separable handle member, such a construction obviating at least one of the abovementioned die-cutting machines and at least one gluing machine.

Additionally, such a one-piece blank will ensure greater economies in material than when the handle member is formed from one blank and the divider structure formed from another.

Moreover, although it is known to form the handle members from a number of plies of material, such handles have not always proved too successful, because many of these have splitand cracked at various stresspoints. Accordingly, it is another object of the present invention to ensure that a multi-ply handle is provided which will have greater flexability.

A still further object is to provide means which will limit the amount of movement of the handle in either of its two directions of movement.

The invention is illustrated, by way of example in the accompanying drawings in which:

FIG. 1 is a plan view of a basic form of one-piece blank;

FIG. 2 is similar to FIG. 1 but shows the obverse side of the blank;

FIGS. 3-6 show different, but consecutive, stages in the folding of the blank;

FIGS. 7 and 8 show the folded blank during uniting to the blank forming the carton shell;

FIGS. 9 and 10 are views similar to FIGS. 1 and 2 but of a different form of one-piece blank;

FIG. 11 is a transverse section of an erected carton embodying-the type of blank shown in FIGS. 9 and 10 but with the handle in a lowered position; and

FIG. 12 is similar to FIG. 11 but showing the handle in an extended or carrying position.

Referring now to the drawings, and in particular to FIGS. 1 and 2, the one-piece blank is cut and scored so as to provide a pair of complementary

primary panels

1 and 2 integrally and hingedly connected together along a common score line 3 having an elongated slot 4 therein. Each end of each

primary panel

1, 2 is integrally and hingedly connected to an end tab 5 by means of a common score line 6. The primary panels I, 2 ultimately form a pair of longitudinal partitions within the carton.

The marginal side edge, remote from the slot 4, of the primary panel 2 is integral with and hinged to a pair of connecting panels 7, by means of a score line 8, a portion of which is incised as at 9.

The connecting panels 7 are. integrally and hingedly connected to to a first outer handle panel 10 along a weakened score line 11 a portion 12 of which is a normal score line. A pair of incisions 13, at right angles to the score line 12, connect the latter to the incision 9 whereby said

incisions

9, 13 and the score line 12 define a mid-body reinforcing tab 14. Opposite ends of the first outer handle panel 10 are integrally and hingedly connected, through the intermediary of score lines 15 to end-body reinforcing tabs 16 each having an extension 17. The first outer handle panel 10 is also provided with a hand hole 18 and it is also integrally and hingedly connected by score line 19 to a first pair of inner reinforcing handle panels 20.

The first outer handle panel 10, through a common score line 21, is also integrally and hingedly connected to a second outer handlepanel 22 having a hand hole 23. The second outer handle panel 22, via scoreline 24, is also integrally and hingedly connected to a second pair of inner reinforcing panels 25 which are, in turn, integrally and hingedly connected to the first pair of inner panels 20 along a common score line 26. The second outer handle panel 22 also has a main body portion 27 provided with a pair of shoulders 28 and the first outer handle panel 10 is also provided with a similar main body portion 29 having shoulders 30.

It will be observed from FIGS. 1 and 2 that each of the handle

inner panels

20, 25 is provided with a cutout 31 approximating in shape to at least part of the

hand holes

18, 23. Moreover, slots 32,- 33 are provided in the score lines 26 the purpose of which will be described hereinafter. It will also be seen that the projecting tabs 17 complement cut-outs 34. Both sides of the onepiece blank are spot-gluedat selected areas indicated by the stipled portions.

In folding the one piece blank so as to provide the divider element and a separable and extensible handle member, the inner

reinforcement handle panels

20, 25 are folded about their

respective score lines

19, 24 so that they overlie the

outer handle panels

10, 22 as is shown in FIG. 3. Similarly, the

body reinforcing tabs

14, 16 are folded along their associated

score lines

12, 15 so that these tabs also overlie the main body portion 29 of the first outer handle panel 10. It will be observed that in this position, the extensions 17 will reinforce very critical areas of the handle, said areas being indicated by arrows Y.

The second outer handle panel 22 and its pair of inner panels 25 is then folded along the

superposed score lines

21, 26 so that they will overlie the first outer handle panel II) and its pair of inner panels 20 as shown in FIG. 4. In this position, of course, the main body portion 27 of the'first outer handle panel 22 will overlie the reinforcing

tabs

14, 16.

Thereafter the blank is folded along the score line 8, as is shown in FIG. 5, and then along the score line 3 so that the resultant assembly will assume the'position shown in FIG. 6. Pressure is then applied to the assembly to bring about adhesion between components, said pressure being sufficient to bring about separation of the handle member, along the weakened score line 11, from the remainder of the blank.

The combined partition and handle assembly A is then positioned on the blank B forming the outer shell of the carton as is shown in FIG. 7, and certain panels of said carton shell are then folded so as to produce a knocked-down carton shown in FIG. 8.

When such a knocked-down carton is erected for filling purposes, a pair of article receiving compartments will be formed, said compartments being separated from one another by means of the pair of longitudinal partitions formed by the

primary panels

1, 2 with the handle located therebetween, a portion of the latter projecting from the elongated slot 4.

Referring now to FIGS. 9 and 10, these depict another form of one-piece blank. Insofar as possible, like reference have been used for the blanks shown in FIGS. 1 and 2 as well as 9 and 10. As will be seen from FIGS. 9 and 10, the second form of blank has similar panels adapted to form the carrying handle, its reinforcing panels and the connecting panels.

The second form of one-piece blank differs from the first form only insofar as the

primary panels

1, 2 are concerned. For instance, it will be observed that a tab 5' is provided adjacent one end of each primary panel and remote from tab 5.

Moreover, each of the

primary panels

1, 2 of the second form of the invention is scored and incised to provide a plurality of sub-panels 40 each integrally and hingedly connected to the associated primary panel along a score line 41. Each of the sub-panels 40 is also integrally and hingedly connected, by means of the score line 41, to an end tab 43.

One side of certain of the sub-panels 40 is provided with a tit 44, the purpose of which will be described hereinafter.

It will be seen from FIGS. 9 and 10 that the blank is provided with glued areas as was the case in FIGS. 1 and 2 and, additionally, one face of each of the end tabs 43 is also coated with glue.

The folding of the blank shown in FIGS. 9 and 10 and its marriage to the carton shell blank is the same as that described above and illustrated in FIGS. 7 and 8.

Referring now to FIG. 11 it will again be seen that each of the

primary panels

1, 2 extends along the central longitudinal axis of the carton to form a longitudinal partition whereas each of the sub-panels 40 extend normal to the said longitudinal partition and the adjacent side wall of the carton to define a transverse partition. It will also be seen from FIG. 11 that the tits 44 form part of, and depend from, the lower edge of each transverse partition. Moreover, each tit is located adjacent the bottom of the carton. The purpose of the tits 44 therefore, is to prevent contact between the bottoms of a pair of adjacent articles in the same row when the carton is carried.

From the above description therefore, it will be apeach connecting panel 7 located between the pair of longitudinal partitions.

Although the cartons described above and illustrated in the drawings relate to an enclosed type of carton i.e. provided with top end and side closure flaps, it will be obvious that the invention is equally applicable to open-topped cartons or other types of cartons including skeletal cartons.
