Kaplan's complete box may be quickly and easily formed by folding the
blanks shown in Figures 1 and 2 along the crease or score lines and the several walls
are secured in proper rectangular position relative to the main top and bottom panels by
folding the corner portions 15 and 23, as indicated in Figure 4, and then turning down
the folds 17 and 24 and pressing them upon the inner surfaces of the triangular corner
portions and walls 12 and 21. No moistening is required and the mere pressing of the
gummed surfaces together forms a secure bond. Kaplan provides (page 2, left column,
lines 6-18) that
[i]t is to be understood that my characterization of the coating or gum as
cohesive but nonadhesive refers to the condition of the composition after it has
been caused to penetrate and adhere to the surfaces of the blanks and has
been dried. In this condition two coated members may be firmly bonded
together by merely pressing the coated surfaces one on the other, but the
coating is non-adherent in that the blanks can be handled or packed in stacks
front to back, one upon the other, without adherence to each other or to other
objects with which the blanks normally come in contact.
Giacovas' invention relates to improvements in self-sealing paperboard
cartons and to a method of coating the closure flaps with pressure-sensitive adhesive
so as to prevent a stack of the collapsed cartons from sticking together and so as to
ensure that the flaps adhere. Giacovas provides (column 1, lines 15-47) that
[n]umerous attempts have been made to devise a self-sealing paperboard
carton having overlapping flaps bearing pressure-sensitive adhesive which when
collapsed, the flaps will not become stuck to each other or to other individual
cartons of a similar type upon being stacked one upon the other for storage or
shipment and before being used.
