Application No. 08/699,572
Giacovas' carton blank is shown in Figure 1. The carton blank includes end and
side walls 11, 12, 14, 16; a side glue flap 18 articulated to the free side edge of the
body side wall 16 and adapted to be connected to the end wall 11; top closure flaps 20,
22, 24, 26; and bottom closure flaps 28, 30, 32, 34. Each of the flaps 20, 24, 28, 32 is
provided on its outer surface when folded inwardly to closure position, with a strip of
paper (see Figure 1A) constituting a tape 42 having a coating of water glue 49 over one
surface thereof and a coating of tacky adhesive 50 over the entire opposite surface
thereof. The tapes are applied along the base portions of the end flaps 20, 24, 28, 32
adjacent to their hinge and articulated connections with the end walls 11 and 14. The
water glue surface 49 of the tape is placed in contact with the base portion of the end
flap in order to fasten the tape to the flap. The surface of the tape with the tacky
adhesive 50 is thus exposed and keeps its strength as it cannot be absorbed by either
the paper material of the tape or the material of the flap, the water glue surface 49
preventing such absorption. In order to protect the tacky adhesive 50 on the tapes and
prevent it from adhering to anything before the carton is sealed, the coating of tacky
adhesive 50 on each flap is covered by a suitable releasable paper cover strip which
extends entirely over and along the tacky adhesive 50. Thus, the
tacky adhesive areas of the flaps are protected by elongated rectangular cover paper
strips indicated at 52, 53, 54, 55.
