BOX AND BOX BLANK
Jesse T. Curtis, Cleveland, Ohio
Application April 23, 1936, Serial No. 76,038
4 Claims. (Cl. 229—37)
This invention is an improvement in boxes and
box blanks and relates more particularly to con
tainers for electrical condenser units which are
adapted to be inserted and sealed therein.
One of the objects of the invention is to con
struct a box from a one piece blank cut from suit
able sheet material and arranged to be folded to
viding end portions for the convenient fastening
of the box to a base or support.
provide a reinforced base or support by which the
The adjoining sections and end ?aps of the
box may be rigidly supported on a ?at surface.

Another object is to provide a box having end
blank are bent inwardly along the weakened or
?aps, a side wall extending beyond the box body,
and an end cover ?ap adapted to form, with the
extended end-of the side wall, an additional rein
forcement for supporting the box rigidly upon a
15 ?at surface.
A further object is to provide a simple, inex
pensive and durable box formed from a single
piece blank/and which is adapted to be folded so
that but one surface of the blank will form the
20 complete outer surface of the box. In this man
outwardly at “I, while the portions H are bent in
an opposite direction at H. In this manner,
when the blank is assembled, it will form a box of
elongated form as shown in Figures 1 and 2.

base for the box which is very desirable in mount
ing the box upon a ?at suface in use.
The sections l and 5 are of su?icient length
that they overlie the extremities of the box when
folded as illustrated in Figures 1 and 2, thus pro- 5
a metallic ?nish may be employed and the box
when folded and assembled according to my in
25 vention, will have its complete outer or exposed
surface thus materially enhanced in appearance.
Other objects and adavantages of the inven
tion will become apparent from the following de
scription of an embodiment of my invention,
30 reference being made to the accompanying draw
ing in which like reference characters are em
ployed to, designate like parts throughout the
.
same.
In the drawing:
Figure 1 is a perspective view of an embodiment
of
invention showing the box assembled and
the ends closed.
Figure 2 isa similar view showing the box ends

partially open.
Figure 3- is a sectional view taken on line 3-3
of Figure 1, and
Figure 4 is a plan view of the blank from which
the box is formed according to the illustrated
451. embodiment of the invention.
I will ?rst proceed to describe the box blank
illustrated in the drawing. The blank is out or
stamped preferably from a single sheet of suitable
materialwsuch as pasteboard, sheet metal or ?bre
50 and conliprises a plurality of side walls or sections,
indicated at i, 2, 3, 4, and 5, the end flaps ‘i and 1,
and the cover ?aps 8 and 9. The sections I and 5
overlie one another when the box is assembled, as
indicated in Figures 1 to 3 inclusive, and in this
manner provide a very rigid, reinforced bottom or
scored lines.
The cover ?aps 8 and 9 are bent l0
It is to be noted that by my invention I am en- 1'5
abled to form boxes of a sheet blank which is
coated or has but one entire surface in color. In
so folding the box the colored or coated ‘surface
may be exposed on all sides of the box, thus giv
ing a very pleasing appearance without neces
sitating the coloring or coating of portions of 20
both the inner and outer surfaces of the blank
sheet in order to insure a completely colored or
coated outer appearance. Furthermore, by my
invention I can accomplish this result without the
necessity of using a composite blank or one com
prising a plurality of separate parts.
At I3 I have perforated the blank so as to pro
vide openings for conductors at one end of the
box. This structure is particularly desirable
when the boxes are used to house electrolytic con
denser pads to which electric conductors are
attached. This a?’ords convenient means for
connecting the pad in a circuit after it has been
sealed in the box. The openings I 3 are prefer
ably located at one end of the box and at points
intersecting the sections 2, 3, and 4 and the ?aps
‘l and 9.
V
The end closure is simple and very durable and
effective.
40
When the box is formed as in Figure 2 the end
closures are completed by binding the flaps 8 or
9 downwardly to overlie the end ?aps E or ‘I re
spectively, while the portion ll of the cover ?aps
is bent outwardly to lie ?at against the extended 45
portions of the members I and 2
The adjacent faces of the members I and 2 may
be secured together with adhesive, rivets, or in
any other suitable manner.
The box formed in accordance with my inven- 50
tion is not only pleasing in appearance, but is
extremely simple in construction and very dura
ble in use. Its durability is enhanced by the
overlying members I and 2 and the reinforced
end closures. ‘By folding the cover ?aps in the 55
