Manufacture of the Carrier
With reference to FIGS. 1 to 6, inclusive, we shall now
describe the folding and gluing steps in manufacturing
the carrier as produced in its ?at folded form for ship
ment by the box manufacturer to the bottler or other
customer. It will be understood that the blank of FIG. 1
we have no intention of excluding such equivalents of the
invention described, or of portions thereof, as fall within
the scope of the claim.
We claim:

rows of three cells each, said blank being formed from

As the blank is fed through the machine, glue is ?rst

FIG. 1. Next, portions of extensions 14- of the side walls
13 are folded about the line 1]‘. FIG. 2 shows the con

Glue is applied to one or both of the extensions 22 (see
the stippled area at 35 in FIG. 2); A second fold is 40

of the blank following this second folding operation.
FIG. 3 also shows the areas over which glue is applied
after the second folding operation, namely the stippled
areas 36, 37, 38, 39, 40 and 41. Now there is performed 45
a third folding operation in which center panel 16 is
folded about line 1"’ into the position shown in FIG. 4.
Next the blank is folded about line 4]‘, and ?ap 26 about
