3 Claims. (Cl. 229-45)
The present invention relates to containers
particularly adapted for the packing of ice cream
and other edible materials which are intended to
be made up in individual packages to be eaten
directly from the container.
v 5
One object of the invention is to provide a
relatively liquid-tight container capable >of being
manufactured in complete form at the box plant
so that the container may be shipped ñat to the
10 user and set up by him without requiring any spe
the container each of which has cooperating
interlocking parts formed thereon at the corners
of the container so as' to secure the cover against
accidental displacement.
Referring more particularly to the drawing, 5
the body portion I of the container comprises a
bottom 2, and side walls 3, 4, 5, and 6, all of
which are preferably formed with outwardly ta
pered edges'. See particularly Fig. 4. The walls
3 and 4 are provided respectively at their ends l0
cial machinery and without the use of fastening ' with flaps 3a, 3b, la, 4b. These naps are formed
with conventional interlocking parts which en
devices other than parts formed on the con
tainer itself.
A further object of the invention is to provide
15 a simple and effective locking means for retain
ing. the cover on the container, such locking
means being disposed adjacent the corners of the
cover and body- portion whereby the cover will
be securely retained against accidental dis
placement. ‘
vA further object of the invention is to locate
the locking parts so that they will be disposed
substantially outside of the compartment in
which the food is contained whereby the food
compartment proper will be substantially smooth
and free from irregularities thus minimizing like
lihood cf contamination by dust or other foreign
A further object is to provide a container of the
type described which will beextremely simple in
form and easy to set up and use, and which will
be effective for the purpose intended.
To these and other ends the invention resides
in certain improvements and combinations of
Y parts, all as will be hereinafter more fully de
scribed, the novel yfeatures being pointed out in
the claims at the end of the specification.
In the drawing:
Fig. 1 is a perspective view of a form of con
40 tainer made in accordance with a preferred em
bodiment of the inventiom'
Fig. 2 is a fragmentary detail view, partly in
section, taken along the line 2-2 of Fig. l;
Fig. 3 is a fragmentary perspective view of
45 one corner of the container showing the inter
locking parts between the cover and the side
Fig. 4 is a view of the blank of the body por
tion of the container;l and
Fig. 5 is a view of the closure blank.
Similar reference numerals throughout the
several views indicate the same parts.
The container of the present invention, as
herein disclosed, comprises a tapered body por
tion or container proper and a cover portion for
gage with each other to retain the body portion I
in set-up condition as illustrated in Fig. 1. The
walls 5 and 6 are, in the present instance, ñrst 15
folded inwardly so that they will lie inside of the
assembled interlocking ñaps 3a, 4a. and 3b, 4b.
Due to the construction just .described it is ap
parent that the body portion of the container
maybe set up and retained ln conditiony to eifec- 20
tively hold the desired material. ‘Other conven
tional means may, if desired, be employed to re
tain the walls in container-forming position.
The cover for the container preferably com
prises a ‘closure panel ‘l having extension naps 25
8, 8 and 9, 9 thereon, all defined from the closure
panel by the score lines indicated. By folding
these extension ñaps upwardly it is to be observed
that a recessed closure is formed that will flt
within the top of the body portion with the upper 30
edges of the extension iiaps lying substantially
flush with the upper edges of the side walls.
extension flaps are preferably flared outwardly
so that when they are bent upwardly, the sides
of the cover will substantially conform to the 35
taper of the side walls.
> A
`Means are provided adjacent the corners of
the body member and cover for locking the cover
to the body member. For this purpose recesses
lo, lo îare formed in the edges of the side waus 40
5 and 6, and tabs Il, IIL are formed on the ends
of extension Vflaps ll,y 8, the position of the tabs
I I, I I being such as to cause them to engage with
in the recesses I0. I0 when the cover is properly
positioned on the body member. The tabs II, II
and recesses Il), l0, are preferably formed of
similar shape so that the tabs will substantially
fit within the respective recesses. The upper
edges of the tabs as well as -the upper part of 50
the recesses are formed so >that the upper por
tions thereof immediately adjacent the corner of
the container extend at approximately .a right
angular relation to the corner of the container.
The upper part of the recesses will, accordingly, 55
provide an abutment serving to more or less posi
tively retain the tabs II, Il.
scription to indicate the scope of the invention.
I claim:
1. A container comprising a bottom and four
that a substantial portion of the ends will lie ‘ side walls, two oppositely disposed walls being of
'I‘he tabs II, I I are preferably of such length
against the inner surfaces of the interengaged
flaps 3a, 3b and la, 4b and be deilected thereby
_to a position substantially at right angles to the
extension ñaps 8, 8, so that the edges of the tabs
will abut -the edges of the recesses. In other
10 words, the ends of the tabs will lie substantially
in the plane of the respective walls 5 and B. Due
to the presence of extension ñaps 9,V 9 restingI
against the walls 5 and 6 these iiaps will serve to
retain tabs II, II from any possible inward
15 movement; and, due to the presence of the inter
engaged flaps 3a, 3b and la, 4b, the tabs I I will
be prevented from any possible outward move
ment. Thus the tabs will be eiïectively retained
within the recesses.
Small openings I2, I2 may, if desired, be
formed in the ilap extensions 9, 9 for the recep
tion of the extremities of a spoon or similar
utensil such as illustrated in my copending ap
plication, Serial No. 36,759, ñled August 19, 1935.
In the use of the container of the present in
vention the body portion and cover will be
shipped ila-t to the packer who desires to utilize
the containers in the packaging of his products.
It is only necessary for the packer to set up the
30 container by bringing the Walls 5 and 6 to upright
position and then interlocking the ilaps 3a, la,
3b, and 4b. The body portion- of the container
is now ready to receive the edible material or
other product which is to be packed therein.
35 extension flaps on the cover will then be moved
_to upright position and the cover pushed down
into the body portion until the locking tabs I I,
Ilsengage within the respective recesses I0, I0.
From the foregoing description it is apparent
40 that a convenient and effective form of container
for edible materials is provided which can be
packed ilatvfor shipment to the user and by him
readily set up and assembled without requiring
special equipment. Due to the position of the.
45 locking elements and their shape the cover is se
curely retained upon the body portion and the
likelihood of its becoming accidentally displaced
is minimized.
At the same time the cover of the
container may be readily removed by grasping
50 and lifting one of the flap extensions of the
cover whereupon the locking tabs will become dis
placed from the recesses I0, I0 permitting the
container to be readily opened for access to the
55 . While the present description sets forth a pre
ierred embodiment of ~the invention, numerous
changes may be made in the construction without
departing from the spirit of the invention, and
it is therefore desired that the present embodi
60 ment be considered in all respects as illustrative
and not restrictive, reference being had to the
appended claims rather than to the foregoing de
