DIVISIBLE CARTON BACKGROUND OF THE INVENTION The present invention relates to divisible cartons which are particularly useful as divisible candy boxes. The inventionalso relates to a unitary paperboard blank from which each divisible carton is formed. The separable smaller cartons or boxes each have a handle formation in a wall thereof. These walls are totally enclosed within the divisible carton before it is separated along a line of perforations circling the carton.

Heretofore, several different types of divisible cartons or containers have been proposed.

The advantages and distinctive features of the divisible carton and of the paperboard blank for making each carton of the present invention will become more apparent from the description of the preferred embodiments.

SUMMARY OF THE INVENTION According to the invention there is provided a paperboard blank for forming a divisible carton separable into two. smaller cartons. The blank includes first and second substantially identical or mirror image blank portions separated by a line of reduced strength which extends between opposite side edges of the blank. Each of the blank portions extends between one end edge of the blank and the reduced strength line and includes a first section and a second section. Each first section extends between the reduced strength line and the second section, the junction between the sections being defined by a fold line extending generally parallel to the reduced strength line. The first section has a pair of spaced apart, generally parallel score lines each extending between the line of reduced strength and one of two free edges in each of the first sections; A bottom panel is defined in the first section between the fold line," the score lines and the line of reduced strength.

First and second side wall panels are hingedly connected at therespective score lines to the bottom panel. At least one portion of the first section extends outwardly from one of the side wall panels, said portion one of the fold lines and one of the end edges of the blank and includes an end wall panel hingedly connected at the fold line to the bottom panel. At least one portion of the second section extends the full length of one of the free edges in the first section and is hingedly connected tothe end wall panel at a score line extending generally parallel to the first mentioned score lines. At least one portion of the second section has a crease therein extending generally parallel to the score lines. An overlapping side wall panel is definedbetween a free edge of the second section, the crease and the score line in the second section, and one of the end edges of the blank. Lastly, a second end wall panel is defined between the last mentioned crease, the free edge in the second section, one of the side edges of the blank and one-of the end edges of the blank.

walls and extends within the carton. adjacent one of the side walls in juxtaposed relationship thereto a distance equal to substantially A the length of the side wall. An internal wall is hingedly connected to each overlapping side wall and is arranged to form an end wall of a smaller carton when the divisible carton is separated into two smaller cartons. Additionally,'a line of perforations extends around the carton midway between the end walls thereof such that the divisible carton can be separated along the line of perforations to form the. two smaller substantially identical cartons. Preferably, the internal wall has a handle formation therein, so that, after the divisible carton is separated into the two smaller cartons, the facing internal walls each form an end wall panel with a handle formation therein for one of the smaller cartons. The handle formation can be.

easily manipulated for extending a handle from the smaller carton.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The divisible. carton of the present invention is identifiled by the reference numeral 10 in FIG. 1. As shown,

- a line of reduced strength, namely, a line of perfora- FIGS. 4, S and 6. It is to be noted that the walls 16, 20, 22, 24, 26 and 26a are continuous and provide the divisible carton 10 with continuous smooth top, bottom and side walls which facilitate the handling and stacking of the carton 10. Also, except for the line of perforations 11, each carton 10 has the shape and appearance of a single unitary carton.

As shown in FIGS. 2, 4 and5, when the divisible carton 10 is divided along the perforated line 11 to form the two smaller cartons l2 and 14, the internal end walls 30 and 30a each have a handle formation 32 or 32a formed therein. The handle formations 32 and 32a are easily extended to form a handle 38 or 38a which extends outwardly from the end wall panel 30 or 30a of each of the cartons 12 or 14. The handle 38 is shown extended in FIG. 3. The manner in which the handle 38 is erected will be explained hereinafter in detail in connection with the description of FIGS. 4, and 6.

The blank 40 from which carton is. assembled is shown in FIG. 4. Blank 40.has a plurality of panels which form the various walls of the carton 10 when the blank is erected. The blank 40 is divided into first and second portions 41 and 41a which are mirror images of each other and which extend between end edges 43 and 43a. Since the portions 41 and 41a are substantially the same, only the blank portion 41 will be described in detail. Corresponding elements in the second blank portion 41a are identified with the same reference numeral and the subscript a appended.

The portion 41 includes a first section 44 and a second section 46. The first section 44 extends from perforated line 11 to a fold line 48 defining the junction between the first and second sections 44, 46. The first section 44 has-a pair of spaced apart generally parallel score lines 51 and 52 which extend between the perforated line and one of two freeedges 53, 54 in the first section 44. A bottom wall panel 56 is defined in the first section between the fold line 48, the score lines 51 and 52 and the perforated line 11. Thus, the bottom wall panels 56 and 56a'together provide or form the bottom wall 24 of the carton 10.

First and second side wall panels 61 and 62 are hingedly connected at the respective score lines 51 and 52 to the bottom wall panel 56. The first section 44 extends outwardly from each of the side wall panels 61 and 62. First and second creases 63 and 64 extend respectively in each of these outwardly extending portions and between the perforated line 11 and one of the free edges 53 or 54 so as to divide each into one of the side wall panels 61 or 62 and a top wall panel 65 or 66. Each side wall panel 61 and 62 is defined between the perforated line 11, one of the score lines 51 or 52, one of the creases 63 or 64, and one 'of the free edges 53 or 54. Similarly, each of the top panels 65 or 66 is defined between the perforated line 11, one of the creases 63 or 64, one of the free edges 53 or 54, and one of two side edges 67 or 69 of the blank 40.

It will be noted that the side wall panels 61 and 61a form the side wall of the carton 10. Likewise, the side wall panels 62 and 620 form the opposite side wall 22 of the carton 10. Again, panels 65 and 65a form the top wall 18 and panels 66 and 66a form the top wall 16 of the carton 10. v

The second section 46 of the blank portion 41 extends between the fold line 48 and the end edge 43 of the blank 40 and includes the end wall panel 26 which is hingedly connected at the fold line 48' to the bottom wall panel 56. First and second portions of the second section extend, respectively, from the end wall panel 26 at least the full length of one of the free edges 53 or 54 in the first section. As shown, these portions extend further outwardly than the free edge 53 or 54 and beyond the end edges of the top panels and 66 in the first section 44. Each of these outwardly extending portions is hingedly connected to the end wall panel 26 at one of two score lines 71 and 72 which extend generally parallel to, but not co-linear with, the score lines 51, 52 in the first section 44. Also, it will be noted that the score lines 71 and 72 are closer to each other than the score lines 51 and 52 so that'when'the end panel 26 is folded upwardly, its side edges at the score lines 71 and 72 will be inwardly of the side wall panels 61 and 62. Then, the first and second overlapping side wall panels 81 and 82 hingedly connected to the end panel-26 at the respective score lines 71 and 72 easily can be fitted within the carton 10 adjacent the side wall panels 61 and 62.

As shown in FIG. 4, each of the outwardly extending portions of the second section 46 in which the overlapping side wall panels 81 and 82 are found extends between one of the score lines 71 or 72, one of the side edges 67 or 69 of the blank, the end edge 43 of the blank and one of two free edges 83 or 84 in the first section. Each of the free edges 83 or 84 is adjacent one of the free edges 53 or 54 in the first section. In this respect, each pair of adjacent free edges 53, 83 or 54, 84, is formed by a slit 85 or 86 formed in the blank portion and extending outwardly from the fold line 48.

The inner end of each of the slits 85, 86 is defined by a cut 87 or 88 which extends at an angle into the blank 40 from the pair of adjacent free edges 53, 83 or 54, 84

in a direction generally toward the perforated line 11 and toward one of the score lines 52 or 51 in the first section and substantially to the fold line 48 which -is generally parallel to, but not co-linear with the slits 85, 86 in the blank portion 41.

Each of the outwardly extending portions of the second section 46 includes a crease 93 or 94 which extends generally parallel to the score lines 71, 72, 51, 52

and between the free edge 83 or 84 and the end edge 43 of the blank 40. As shown, the crease 93 forms a junction in one portion of the first section 46 between the overlapping panel 81 and panel 30 which forms an overlapping internal wall within the carton 10 prior to the division of the carton into the two smaller cartons 12, 14, after which the wall panel 30 forms the end wall 30 of the carton 12. Likewise, the crease 94 forms a junction in the other portion of the second section 46 between the overlapping panel 82 and another panel 96 which forms an overlapping internal wall 96 which will be folded behind the end wall 30.

It will be apparent that each of the overlapping side wall panels 81 and 82 is defined between one of the free edges 83 or 84, one of the score lines 71 or 72,-the end edges 43 and one of the creases 93 or 94. Similarly, each of the internal wall panels 30 and 96 is defined between the crease 93 or 94, the free edge 83 or 84, the

side edge 67 or 69 of the blank 40 and the end edge 43 of the blank 40.

, An end flap 100 is hingedly connected to the end wall panel 26 at a second fold line 102 which is spaced from and parallel to the first fold line 48. Side edges 103 and 104 of the end flap 100 are located outwardly of the score lines 71 and 72. The portion of theend edge 43 defining one side edge of each of the overlapping side wall panels 81 and 82 is stepped or recessed as indicated at 107 and 108. This recess or inner edge 107 or 108 is adapted to accommodate the extending edge 103 or 104 of the end flap 100 when it is folded over the overlapping side wall panels 81 and 82. To facilitate this folding, two cuts, 109 and 110 extend inwardly from the inner edges 107 and 108 to the score lines 71 and 72 and to the second fold line 102 which is generally cQ-linear to the inner edges 107 and 108.

Each of the end wall panels 30 and 96 has a handle formation, such as 32 in the panel 31) and a handle formation 112 in the panel 96. The handle formation 32 is defined by an elongated'opening 114 which extends in panel 30 in a direction generally parallel to the edges 83 and 43. Spaced from each end of the opening 114 are two cuts 115 and 116 which extend from a point midway between the edges 43 and 83 to the edge 83, which forms a bottom edge of the panel 30 when it is folded to form an internal wall in the carton 10. The U- shaped handle member 38 is defined between the opening 114 and the cuts 115 and 116. The ends of the leg portions of the member 38 are hingedly connected within the panel 30 at score lines 117 and 118 so that the handle 38 can be pulled outwardly and extended as shown in FIG. 3.

In like manner, the handle formation 112 in wall panel 96 is defined by an opening 124, two cuts 125 and 126 and two score lines 127 and 128 which define therebetween and the end edge 43 a U-shaped member 130. It will be noted that the cuts 125 and 126 extend from a point between the edges 43 and 84 to the edge 43, which forms a top edge of the internal wall 96 located behind the panel 30 whenthe'blank 40 is folded to form the carton 10, as best shown in FIGS. 5, 6 and 7- To erect the carton 10, the end panels 26 and 26a are folded upwardly and the secondsections 46 and 46a are formed progressively into rectangles or boxes as shown in FIGS. 5, 6 and 7. The end flaps 100 and 100a are folded over as best shown in FIGS. 6 and 7. In the illustrated embodiment, the panels 96 and 96a are folded behind the panels 30 and 30a. The panels 30 and 96 combine to form a double strength internal wall which faces another double strengthv internal wall formed by the wall panels 30a and 96a. Also, it will be noted that the handle formations 32, 112, 32a, 112a are located in the panels 30, 96, 30a, 96a inside the car- 7 ton 10. After the two boxlilre formations, which are open at the top, are formed by folding the second sections 46 and 46a, they are folded inwardly over and onto the bottom wall panels 56 and'56a, as shown in FIGS. 5, 6 and 7. Then, the panels forming the side walls 20 and 22 and the top walls 16 and 18 are folded upwardly and over the boxlike formations with the top wall 18 being folded over first and then the other top wall 16 being folded thereover. If desired, prior to the folding over of the wall 16 on the wall 18, an adhesive can be applied to the upper surface of the wall 18 or to the underside of the wall 16 for securing the same together.

In the erected carton 10, the overlapping side wall panels 81 and 82 will be juxtaposed the side wall panels 61 and 62 respectively. If desired, the panels 81,61 and the panels 82, 62 can be secured together by an adhesive. Also, the end flap 100 can be adhesively secured underlying the top panel 18. In this way, a substantially rigid divisible carton including two substantially rigid smaller cartons is provided.

After the cartons 12 and 14 are separated by breaking the carton 10 along the line of perforation 11, the handle formations 32 and 112 can be easily extended. The U-shaped handle 38 is folded outwardly and the U-shaped handle 130. hidden from view in FIG. 2 behind the handle 38 is folded downwardly and then projected outwardly underneath the handle 38 as clearly shownin FIG. 3. This provides a firm, double-strength handle. It can be appreciated that upon separation, each of the smaller cartons 12 and 14 are unitary cartonswith each having asmooth shape and appearance.

A modified blank for forming a divisible carton in accordance with the invention is designated in FIG. 8. The blank 140 is similar to the blank 40 except that in the second section of each blank. portion thereof, the panels, i.e., panels 141, 142, 141a and 142a which form the internal walls within the carton and later the end walls of each smaller carton, have a different handle formation therein. In this respect, the overlapping end wall panel 141 is divided by a crease 143 into two panel portions 144 and 146. The outermost panel portion 146 has an elongated opening 148 which extends generally parallel to the crease 143. This opening 148 de fines part of a handle formation. The panel portion 146 is adapted to be folded outwardly so as to form a handle after the divisible carton fonned from the blank 140 is separated into the two smaller cartons.
