7 Claims;
(01. 229-16)
The invention relates to a cake box..
,
The object of the present invention is to pro
vide a strong, practical and attractive cake box
,of simple and comparatively inexpensive con
5 struction, which may be easily set up and ar
ranged for use, and which after assembly is
adapted to be collapsed to a ?at condition for
shipping or storing.
A further object of the invention is to provide
scored one-piece blank from which the box is
formed.
In the accompanying drawings in which is
illustrated the preferred embodiment of the in
vention, l designates a die-cut and die-scored 5
one-piece blank constructed of cardboard or
other suitable material, and preferably reinforced
and ornamented with a layer of metal foil, but
any other suitable material may, of. course, be
10 a hexagonal cake box formed by die-cutting and ' employed in the construction of the blank. The 10
die-scoring from a one piece blank and provided blank is die-scored at 2 to form a hexagonal
at diametrically two opposite sides with perma
bottom 3 which is connected at one side with a
nently connected parallel side walls and having hexagonal top 4 by a side wall 5 formed integral
, at the other four sides interlocking wall-forming
with the top and bottom of the box. The top
15' ?aps and provided also with closure ?aps hinged of the box is die-scored at 6 and the die-scoring 15
to and forming extensions of said permanently
I

connected parallel side walls and foldable over
and reinforcing the interlocking ?aps and en
tirely concealing the same to present a smooth
attractive appearance at the sides where the
box may be opened to obtain access to its con
tents.
.
’
Another object of the invention is to provide
simple, practical and e?icient frictional locking
25 means for securing the closure flaps over the
interlocking ?aps adapted to enable the closure
flaps to be readily secured in their closed posi
tion and capable of enabling the cake box to be
readily opened without tearing or otherwise in
30 juring the same.
.
With these and other objects in view, the in
vention consists in the construction and novel
combination and arrangement of parts herein
after fully described, illustrated in the accom
35 ,panying drawings and pointed out in the claims
hereto appendedfit being understood that vari
ous changes in the form, proportion and minor
details of construction, within the scope of the
claims, may be resorted to without departing
40 from the spirit or sacri?cing any of the advan
tages of the invention.

for hinging integral bottom and top interlocking
?aps 1 and 8 to the bottom and top of the box.
The blank is provided at the side of the top 4 2o
diametrically opposite the side wall 5 with an
integral side wall 9 hinged to the top- by the
scoring 6 and extending from the top wall 4 and
provided with an attaching ?ap l0 hinged to the
side wall 9, the hinge connection being formed 25
by scoring II. The attaching ?ap I0 is secured
by suitable ‘adhesive or other means to the upper
face of the bottom 3 at the side diametrically
opposite the side wall 5 whenvthe blank is assem
bled to form the box. In assembling the blank
to form the box the side wall 5 is swung up
wardly to a vertical position perpendicular to the
bottom 3 and the top 4 is swung to a position‘
over the bottom 3 in parallelism with the same
and the side wall 9 is swung downwardly to a 35
position perpendicular to the bottom and top of
the box. The attaching ?ap is then secured to
the upper face of the bottom of the box. This
provides parallel side walls at spaced points at
diametrically opposite sides of the box.

The interlocking ?aps ‘I and 8 are connected to
the sides of the top and bottom between the side
walls of the box and each of the interlocking
flaps is provided at one end with a cutaway por
tion l2 and has a substantially lobe-shaped 45
tongue 13 located at the inner end of the cutaway
portion and rigid with'the interlocking flap. The _
interlocking'?aps of the bottom and top are re- ‘
versely arranged and are adapted through their
hinge connection with the top and bottom 3 and 50
4 to be swung into interlocking engagement in a
vertical position, thereby forming walls for sub
stantially closing the sides of the box between
the walls 5 and 9 and con?ning the contents of
the box within the same.

The parallel side walls 5 and 9 are‘ provided at vided with means for securing it to the bottom
wall, interlocking ?aps arranged in coacting pairs
their ends with integral extensions forming clo
sure ?aps l4 and i5 and hinged to the side falls and extending from the bottom and top of the
box at the sides thereof between said walls, the

vided at their outer ends with hinged extensions members of ‘each pair of interlocking ?aps being
l8 and I9. The hinge Joints of the extensions I8 ' provided with means for engaging each other,
and closure ?aps extending from the ends of the
and I! are formed by scoring 20 and 2|.
The closure ?aps are adapted to be folded over
the interlocking ?aps and the extensions II and
said walls and hinged to the same andfoldable
over the interlocking ?aps and having friction
fitting portions insertable between the adjacent
ends of the pairs of interlocking ?aps.

While the improvements‘ are shown applied to
20 a hexagonal cake box they are also applicable
to other forms of polygonal boxes. The box may
be ornamented in any desired manner and the
vtop may be, as illustrated in the accompanying
drawings, provided with openings 22 of segmental
or other form for ‘enabling the contents of the
box to be .viewed by prospective purchasers.

When the closure ?aps are folded over the inter
locking ?aps they reinforce the interlocking flaps
and strengthen the box at the sides provided with
the interlocking flaps and at the same time they
completely cover and conceal the interlocking
?aps and contribute to the production of a strong
attractive box. The interlocking [?aps sti?en the
box when the outer closure ?aps with their fric
tion ?tting marginal edges are in place over- and
