Star divider

A divider is disclosed which may be assembled in several different multicellular configurations. The divider is formed from a one-piece rectangular blank separated into two panels by a central longitudinal slitted-and-scored line. Each panel is further divided into two end segments and four intermediate segments by transverse score lines. The divider is assembled without gluing, and can be used to divide a single carton into five alternate cellular configurations.

BACKGROUND OF THE INVENTION 
This invention relates to carton dividers, and is particular to a one-piece 
cushioning divider which may be adjusted to form several different 
multi-cellular configurations. 
Adjustable dividers are used for packing variably sized items, such as 
fruits and vegetables, which are sold by weight. The produce is generally 
graded by size before it is packed, and items of like size are packed 
together. Honeydew melons, for example, are graded into five size ranges. 
Packing each grade in a separate-sized carton is inefficient and 
expensive, since it is impossible to predict in advance how many melons 
will fall into each size range. Since the fruit is perishable, cartons and 
dividers cannot be manufactured "to order" after the melons are graded. 
Furthermore, it is desirable to pack about the same weight of melons in 
each carton. In practice, one or two carton sizes are used, along with a 
divider which can be adjusted by folding to form the required number of 
cells. An adjustable divider makes it possible to pack 4 very large, 5 
large, 6 medium, 8 small, or 10 very small melons in the same carton using 
the same divider. 
The prior art contains a number of adjustable dividers. However, these 
dividers are held in shape by a glued seam. Gluing is slower and more 
difficult to automate than slitting, scoring, or folding. If the glued 
bond is poor, or the seam is inacurrately placed, the divider may fail in 
use. Even when the gluing is done properly, this step retards the whole 
divider-making operation. This is an especially critical problem since the 
dividers are used to pack perishables with a relatively short harvesting 
season. At harvest time, dividers must be produced rapidly, accurately, 
and in very high volumes. 
SUMMARY OF THE INVENTION 
The divider of this invention is designed to overcome the drawbacks of the 
adjustable dividers known to the prior art. It is assembled from a 
rectangular blank, and does not require a gluing step. Depending upon the 
method of assembly, it may be used to divide a container into 4, 5, 6, or 
8 cells, suitable for packing 4, 5, 6, 8, or 10 melons. 
The present divider is formed from a rectangular blank which is divided 
into two panels by a central slitted-and-scored line extending 
longitudinally across the blank. Each panel is further divided into two 
end sections and four intermediate sections by five transverse score 
lines. The end sections of the first panel are connected to the 
corresponding end sections of the second panel along the scored portions 
of the central longitudinal line. The intermediate sections of the first 
panel abut the corresponding intermediate sections of the second panel 
along the slitted portion of the central longitudinal line. The divider is 
assembled by simply folding along the central longitudinal line and then 
exerting inward pressure on opposite ends of the blank to produce further 
folding along some or all of the transverse score lines. Gluing is not 
required. Accordingly, the divider of the present invention may be 
machined and assembled rapidly in large quantities.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
The blank from which the divider is assembled is shown in FIG. 1 of the 
drawings. The divider is generally denoted by the reference number 10 and 
the blank by 10B. Blank 10B includes first and second panels, denoted by 
numbers 11 and 12 respectively, separated by a central longitudinal line 
generally denoted by 20, with scored portions 21 and 22, and cut portion 
23. In the preferred embodiment, portion 23 is a slitted line, but a 
larged die-cut opening may be made without departing from the spirit of 
the invention. Scored portions 21 and 22 are preferably double-scored 
lines. 
The first panel 11 is divided into first and second end segments 31 and 36, 
and first, second, third, and fourth intermediate segments, 32, 33, 34, 
and 35 by transverse score lines which are double-scored in the preferred 
embodiment. First intermediate segment 32 is foldably connected to first 
end segment 31 along transverse score line 50 and to second intermediate 
segment 33 along transverse score line 51. Third intermediate segment 34 
is foldably connected to second intermediate segment 33 along transverse 
score line 52 and to fourth intermediate segment 35 along transverse score 
line 53. Fourth intermediate segment 35 is foldably connected to second 
end segment 36 along transverse score line 54. 
The second panel 12 is divided into first and second end segments 41 and 
46, and first second, third, and fourth intermediate segments, 42, 43, 44, 
and 45 by transverse score lines. First intermediate segment 42 is 
foldably connected to first end segment 41 along transverse score line 55 
and to second intermediate segment 43 along transverse score line 56. 
Third intermediate segment 44 is foldably connected to second intermediate 
segment 43 along transverse score line 57 and to fourth intermediate 
segment 45 along transverse score line 58. Fourth intermediate segment 45 
is foldably connected to second end segment 46 along transverse score line 
59. 
The first end segment of the first panel, 31, is foldably connected to the 
first end segment of the second panel, 41, along longitudinal score line 
21. The second end segment of the first panel, 36, is foldably connected 
to the second end segment of the second panel, 46, along longitudinal 
score line 22. The intermediate segments of the first panel abut the 
corresponding intermediate segments of the second panel along longitudinal 
slit 23. In the preferred embodiment, all of the intermediate segments are 
substantially equal in size. 
The first step in assembling the divider, which is common to all assembled 
configurations, is shown in FIG. 2. Blank 10B is longitudinally folded 
along central line 20 so that the first and second panels are brought into 
face-to-face relation. Assembly of the divider is then completed by 
exerting inward pressure on the two sets of end segments to produce one of 
the configurations illustrated in the following figures. 
The first of the assembled configurations is illustrated in FIG. 3. Inward 
pressure is exerted on opposite ends while the first and second end 
segments and the first and fourth intermediate segments of the first panel 
are held in face-to-face relation to the corresponding segments of the 
second panel. Thus the first panel is bent concavely along transverse 
score lines 51 and 53, and convexly along transverse score line 52, so 
that its second and third intermediate segments 33 and 34 are brought into 
face-to-face relation. Similarly, the second panel is bent concavely along 
transverse score lines 56 and 58, and convexly along transverse score line 
57 so that its second and third intermediate segments 43 and 44 are 
brought into face-to-face relation. A cruciform divider is thereby 
obtained. This divider may be inserted into a container, generally denoted 
by reference numeral 60, to form four rectangular cells, as shown in FIG. 
3. This configuration is particularly well adapted for packing the largest 
grade of melons, which are shipped four to a box. 
The second assembled configuration is illustrated in FIG. 4. Again, inward 
pressure is exerted on the ends of the divider, bending the first panel 
concavely along score lines 51 and 53, and convexly along score line 52, 
and bending the second panel concavely along score lines 56 and 58, and 
convexly along score line 57. However, less pressure is exerted in forming 
this third configuration than was exerted in forming the first 
configuration, so that a substantially diamond-shaped central cell is 
formed by segments 33, 34, 43, and 44. The divider is then inserted into 
the container to form five cells, as shown. 
The third assembled configuration is illustrated in FIG. 5. As inward 
pressure is exerted on the ends of the divider, each panel is allowed to 
bend along all five transverse score lines. The first panel is bent 
convexly along score lines 50 and 54, and concavely along score lines 51, 
52, and 53 to form a first diamond-shaped cell. The second panel is bent 
convexly along score lines 55 and 59, and concavely along score lines 56, 
57, and 58 to form a second diamond-shaped cell. This configuration is 
suitable for packing six intermediate-sized melons. 
The fourth assembled configuration is illustrated in FIG. 6. As inward 
pressure is exerted on the ends of the divider, the first panel is bent 
convexly along score lines 50, 52, and 54, and concavely along score lines 
51 and 53. At the same time, the second panel is bent concavely along 
score lines 55, 57, and 59, and concavely along score lines 56 and 58. A 
first diamond-shaped cell is formed by segments 32, 33, 42, and 43, and a 
second diamond-shaped cell is formed by segments 34, 35, 44, and 45. When 
placed in a rectangular box, the divider forms six additional cells so 
that eight melons may be packed. 
The cruciform divider of the first assembled configuration is also used to 
form the fifth assembled configuration, as shown in FIG. 7. The four 
triangular cells formed by the divider are well-adapted for packing the 
smallest grade of melons, which are shipped in boxes of ten. 
It will be obvious to one skilled in the art that the divider of the 
present invention may be formed from corrugated paperboard, heavy kraft 
paper, flexible plastic, and many other materials. In addition to 
cushioning the articles to be packed, the divider increases the stacking 
strength of the filled container. This divider will obviously be useful 
for packing many different articles although it has been described 
primarily as a melon divider. Modifications will occur to those skilled in 
the art in view of this disclosure which are nonetheless within the spirit 
of this invention.
