1 Claim. (Cl. 229-43)
This invention relates to a self-suspending box of paper

Additional objects of the invention are to provide a

and the back is about 2.75 inches high. In a box of
those dimensions the adhesive containing panel is about
1.75 inches long and about 9.75 inches wide with a sub
stantial area of the inside surface of the panel 32 covered
with the pressure sensitive adhesive means 34. It is pref
erable that the paper be about 0.03 of an inch in thickness
when it possesses the above mentioned dimensions. Of

various dimensions from those speci?cally mentioned
cover ?ap panel 52 is equal to the length of the adhesive
carrying cover ?ap panel 32. The masking strip 36 is
then removed from the pressure sensitive adhesive means
34 and the shelf extender box 10 is ready for attachment
to the shelf 8. The attachment to the shelf is preferably
accomplished by ?rst lining up in adjacent relationship
the top of the marginal cover ?ap panel 26 with the top
of the shelf 8, as in FIG. 4 and then bending outwardly
and downwardly the panels 32 and 52, after the masking

wide temperature range such as down to freezing and up
to about 150° F. Other blanks than that which is shown
in FIG. 5 can also be used in this invention provided that
they employ a cover ?ap‘ such as that shown by nu
meral 24.
In a self~suspending box comprising a rectangular paper
box having a bottom, back, front, and opposed side walls,
a cover ?ap, said cover flap being homogeneously integral
with the top of said back, the improvementiwhich com~
prises having a ?rst longitudinal foldable scoring line
The blank as shown by FIG. 5 is assembled by bending
upwardly the scoring surrounding all sides of the bottom 20 between the back and cover ?ap for the outward folding
of said cover ?ap, said cover ?ap having homogeneously

of sides 18, 18 are bent inwardly, the panel 58 of front 14 25 lines on said cover ?ap, wherein the scoring line between
the middle and marginal panel registers with the scoring

between the box back and cover ?ap upon out-and
and the front free margin 40 is bent upwardly at the
down folding of the scoring line between the ?rst and
scored line 62 and secured by tongue 42. The scored
middle panel, the width of the ?rst panel and the width
line 62 is preferably an intermittently perforated or die
of the middle panel being equal to each other and the
score line. The rear side ?ap extensions 20, 20 are bent
