(Cl. 229-27) This invention relates to a carton and more particularly to a carton with upstanding longitudinal and lateral partitions dividing it into a number of compartments.

A number of different proposals have been made for constructing cartons of this type out of a single blank of material. The blank is provided with sections which include wall-forming panels and extensions of the panels adapted to form the floor and the upstanding partitions.

The present invention provides a structure along these same general lines but of an improved construction which is easy and economical to manufacture, convenient to assemble and effective in use. In accordance with the applicants structure, the blank includes two similar pairs of different connected section. A first section of each pair has a rectangular wall-forrning panel having a rectangular floor-forming flap hingedly connected to it and, hingedly connected to the floor-forming flap, a transverse partitionforming flap. The second section of the pair has a rectangular wall-forming panel and a floor-forming fiap hingedly connected to it. This flap is of regular trapezoidal formation tapering to a narrow side adapted to lie along the centerline of the container. To the tapered side of the flap is hingedly connected a partition-forming extension made up of a narrow rectangular panel, a fin connected to this panel near its extremity and extending laterally therefrom and separated from it by a tapered slot and a connecting flap hingedly connected to the side of the rectangular panel. The fin has an inner edge parallel to the hinged edge of the rectangular panel. The narrow rectangular panel and fin form part of the longitudinal partition, the slot giving passage to one of the transverse partitions. The transverse partition preferably has one half higher than the slot and the other half lower. The lower half can thus pass through the slot to allow the higher half to abut against the longitudinal partition. The connecting flap is adapted to be bent at right angles to the rectangular partition and to abut and be adhesively secured to a lateral partition. Top flaps are hingedly connected to the wall-forming panels.

The blank is assembled into a container in a manner which will be readily understood by those skilled in the art from the operation of analogous devices.

The invention has been generally described and it will now be referred to in more detail by reference to the accompanying drawings illustrating a preferred container and preferred blank for making it, in which FIGURE 1 is a top plan view of the assembled container before it is filled with bottles.

FIGURE 2 is a perspective view of the container shown in FIGURE 1 with part of the walls cut away to show the partitioning.

FIGURE 3 is a vertical cross-section along the line 3-3 of FIGURE 1.

FIGURE 4 is a vertical cross-section along the line 44 of FIGURE 1.

FIGURE 5 is a plan view of a blank suitable for makthe container of the previous figures.

Referring more particularly to the drawings, the container is preferably made from a single blank A of material the reverse side of which is shown in FIGURE 5. The blank will first be described for facility in understanding the invention, but the numbers given to the parts of the blank will also be given to the parts of the container 3.,ll3,53 Patented Jan. Zl, 1964 "ice made from the blank. The blank is die-cut and scored to form (looking at the reverse side of the blank right side up as in FIGURE 5) in sequence, an end wall-forming panel 15 hinged to a side wall-forming panel 17 which is in turn hinged to an end wall-forming panel 1-9 which is in turn hinged to a side wall-forming panel 21.

The respective panels are provided with top flaps hinged thereto as follows; to the panel 15, the flap 23; to the panel 17, the flap 25; to the panel 19, the flap 27; to the panel 21, the flap 29'.

In accordance with the invention, appendages of the wall-forming panels form the floor of the container and longitudinal and laterally extending interlocking partitions which project upwardly from the floor of the container. With this in mind, the panel 15 is provided with a floorforming flap 3d. The bottom flap 3 1 is hinged to a flap 33 which forms one of the laterally extending partitions. The flap 33 has an outer margin of the form shown including a straight edge 33a, inwardly-extending center edge 33b terminating in a shallow slot 54, and a curved edge 33c extending from the other side of the slot 34.

To the bottom of the side panel 17 is hinged a floorforrning regular trapezoidal flap 35 which in turn has hinged to one diagonal side the triangular flap 37. The flaps 35 and 47 form a part of the fioor of the container. Hinged to the narrow side of the flap 35 is a rectangular flap 39, to the right hand side of which is hinged the flap 41 which is separated from the flap 37 by the cut 43. To the side of the flap 39 near its bottom edge is laterally connected through a narrow connecting part 47a, a fm 4-5. The fin 45 has an inclined inner side 45a separated from the flap 39 by a tapered slot 4-7. The top edge 45b of the flap 45 is in line with the hinge between the flaps 3-5 and 59 The end panel 19 sirnilarly to the end wall-forming panel '15, is provided with a hinged flap 51 which in turn is hinged to a flap 53. The flap 55 has an outer margin similar to that of the flap 33 including a straight portion 53a, an inwardly extending margin 53b ending in a slot 54 and a curved portion 530.

The section containing the panel 21 and the flap 29 is similar to the section containing the panel 17 and the flap 25. T o the panel 21 is hingedly connected a regular trapezoidal flap 55 to one side of which is hingedly connected a triangular flap 57. To the short side of the trapezoidal flap 55 is connected a narrow rectangular panel 5?. To the right-hand side of this panel is connected a flap 6 which is separated from the flap 57 by a cut 63. A fin 65 is connected to the panel 59 by a narrow adjoining portion 6% and extends inward separated from the panel 59 by a slot 69. The fin 65 has an edge 65:: parallel to the score line 55:; between the

flaps

55 and 59.

To the panel 21 is hingedly connected a laterally extending narrow long flap 22 which serves as a gluing strip for connecting the wall panel 21 to the wall panel 15 when the container is assembled.

Assembly The manner of assembly of the container will be clear to one skilled in the art. As seen in FIGURE 2, the

panels

15, 17, 19 and 21 of the blank form the side and end walls. The

panels

35 and 55 are bent inwards to form part of the floor, and the

panels

31 and 51 bent inwards to overlie the

panels

35 and 55 respectively. The

panels

33 and 53 are bent upwards to form transverse partitions. The

parts

39 and 45 and 59 and 65 respectively combine to form the longitudinal partition. The

parts

41 and 61 are bent laterally to be adhesively secured to the

parts

33 and 53 respectively fulfilling the dual function of reinforcing the transverse partitions and connecting the longitudinal and transverse partitions. The

panels

33 and 53 are received by the slots 47 and 69 allowing the longitudinal and transverse partitions to intersect. The flap 37 is folded over on top of the flap 35 and adhesively secured to the underside of the area 37a of the part 31 shown by the shading on FIGURE 5. Likewise, the flap 57 is folded on top of the fiap 55 and adhesively secured to the underside of the area 57a of the part 51.
