CONTAINER BLANK
Walter G. Reagan, Lebanon, Ind.
Application August 29, 1936, Serial ‘No. 98,509
8 Claims.
(Cl. 229‘-1.5) "
It has long been customary, in the retail vending
of popped corn, to package the same in ordinary
commercial paper bags or boxes in various sizes,
depending upon the charged price. The vendor
5 has been under the necessity of carrying a stock
of bags of different sizes and a package of this
kind is somewhat dif?cult to handle during con
sumption of the popped com. A reasonably
grease impervious bag is relatively expensive.
The object of my present invention is to provide
10
a paper blank so formed that a vendor may
readily develop it into a conical container in any
one of a plurality of sizes to form a container of
desired capacity, which container may be more
readily handled by the consumer and the cost of
which, to the merchant, will be materially less
than the preformed bags now commonly used.
While the blank has been primarily designed
as a popped corn container, it will, of course, be
20 readily understood that containers formed from
the blanks will be equally useful in the vending of
a large variety of articles.
The accompanying drawing illustrates my in
vention:
Fig. 1 is a face view of the blank,
25
Fig. 2 a perspective view of one of the blanks
formed into a large capacity container,
Fig. 3 a similar view of the same blank formed
into a smaller capacity container, and
Fig. 4 a perspective view showing the blank in
the preliminary stage of development into a con
tainer.
In the drawing, It? indicates the main body of
the blank, a portion of the edge of which, as indi
cated at I I, is arcuate, struck approximately from
a center I2 in or near the opposite edge portion
I3 which is straight, or nearly straight. The ar
cuate portion I I at one end is ?anked by an edge
portion l4 and at the other end by an edge por
tion I5 which, in turn, is flanked by an edge por
tion It
portion
portion
I4 is a
which is substantially parallel with edge
I4 and connects with one end‘of edge
I3. At the corner formed by edges I3 and
locking tongue 11 which, at its junction
“ with edge portion It, forms an entrant notch I8.
Formed through the main body I0 adjacent the
arcuate edge II and variably spaced from edge
M are slits A and B.
The above described blank is conveniently
formed of comparatively thin, but reasonably
sti? and tough paper, although, of course, it can
be formed from any other suitable sheet material.
The user, by grasping edge I6 and swinging the
same upwardly and inwardly about an axis sub
55 stantially parallel with said edge to roll the blank
into a loose roll, as. shown in Fig. 4, may readily
insert tongue I‘! into-slit A, whereupon, by plac
ing the two hands at opposite ends of the rolled
blank, as shown in Fig. 4, and- simultaneously
exerting axial pressure and oppositely rotating
the hands in the direction indicated by the ar
row, the blank may be tightened to true conical
form as a container, as illustrated in Fig. 3.
If
the tongue I‘! be inserted in the slit B, a large
size container will be produced, as indicated in 10
Fig. 2. The blank is dubbed off at I5 in order
that the adjacent portion of the blank, when
brought to container form, will, by reason of its
resiliency, snuggle against the inner surface of
the cone. This dubbing off is not absolutely 15
essential but it contributes materially to the pro
duction of a, better looking container for when
the blank is so formed, the edge portions I5 and
I6 hug the inner surface of the cone without
20
-forming a loose ?ap.
It will be readily understood that by the simple
expedient of providing a multiplicity of slits like
the slits A and B variably spaced, the available
range of container sizes may be increased. The
arcuate edge II develops into an even ended cone, 25
which, of course, is desirable for looks though
not absolutely essential.
It is. desirable also that the edge I3’ be straight
from edge IE to approximately slightly beyond
center point I2 and the remaining portion con 30
tinue to its junction with the notch I8 at a very
slight angle, as indicated in Fig. 1, as otherwise
there is a slight tendency to looseness of the
edge portion I3 along the outer face of the cone.
When the blank is coni?ed, the apex of the cone
will be adjacent edge I3-I3’ and in the claims
this line is considered a base line, a medial per
pendicular to which will divide the blank into two
halves, one of which halves will carry the tongue
40
and slits.
As stated above the apex of the cone formed
from the blank will be adjacent the edge I3, l3’,
one corner of which carries the tongue H. The
slit for receiving this tongue must be in the upper
half of the blank, considering the apex line as 45
the base line.
I claim as my invention:
1. A blank for conical packages, comprising a
polygonal sheet of ?exible somewhat resilient
material, such as paper, provided at one corner 50
with a locking tongue ?anking a re-entrant notch
and also having a tongue-receiving slit within
that half of the blank which carries the tongue
and within the quadrant of said half most remote
from said tonsua.
