In the present invention the container may 9 within the sheets is such that it will not easily
sometimes be used more than once, but more
often the container becomes soiled or wet after
being used so that it cannot be used continually
and must therefore be replaced. It is essential
for this reason to make the container as cheaply
as possible and yet in such a manner that it will
efficiently and readily accomplish the purpose for
which it is used.
The present invention is concerned more par
ticularly with providing an inexpensive method
of packing, particularly for such food stuffs as
20 are perishable during shipment.
The present invention is an improvement on
my previous application Serial No. 639,265, and
inasmuch, is a more convenient and inexpensive
container which in cases is preferred to the con
tainer of the prior application.
The present invention will be more fully un
derstood in connection with the following de
scription and the drawing showing an embodi
ment of the same, in Which:--Figure 1 shows an interior liner of the con
tainer.
Figure 2 shows a section through the container
in its open position,
Figure 3 the container entirely in a closed posi
tion, and,
Figure 4, a section through the inner liner of
Figure 1.
.
The container is shown as it is used in Figure 3.
In this ligure l indicates the outer box which
40 may be constructed of corrugated paper walls with
the ?lutings at the inside. The box may be made
of one piece in the usual fashion with the top and
bottom covers 2 and. 3. Within the box is held
the inner container 4, which comprises a non
45 stiff or flexible bag element 5 having a stiff bot
torn cover 6 as indicated more clearly in the other
ñgures. The bag element 5 may have water
proof face papers such as 'l and 8 shown in
Figure 4 with insulating elements 9 between
50 which may be batting or ground paper or some
other suitable light ñexible insulating material.
As indicated in Figures 1 and 4, the inner liner
is composed of the inner sheet 'l and the outer
sheet 8. These sheets form a continuous lining
55 element about the inside walls of the container.
come out. This is true in the case of batting
or wadding, and particularly in the present in»
vention where the lower end is sealed when the
container is in use as will be presently described.
At the lower end of the liner or inside con
tainer 4, there is found a stiff corrugated sheet
I2 which passes about the entire end of the con
tainer forming a border of the same. This cor
rugated sheet is glued or adhered to the lower
end of the liner as indicated at I 3. Just opposite
the end I4 of the liner is positioned a scoring
line VI5 upon which the corrugated element is
folded when the lower end of the liner is closed
to form the bottom of the inner container.
As indicated in Figure 1, the corrugated paper
is cut at the corners l1 so that they may be folded
as an ordinary box. The corrugated board or
paper l2 in being folded, folds over the lower
end I4 of the liner thus sealing effectively the
batting at the end. The lower 'end in its folded
position forms a stiñ ñat bottom over the inner
container, and provides as` is indicated in Figure
3 horizontal flutings I8 for circulation of the air
within the container about the bottom of it, the
container 4 itself not ñtting so tightly but what
the circulation at the sides is possible. The top
part of the container 4 may be closed over as 35
indicated by the closing flaps I9 in Figure 3, and
if desirable, a refrigerant may be placed above
this.
The whole container, comprising the inner and
outer elements may be shipped as one in a flat 40
package with the ends lying flatly opened as in
dicated in Figure 2. The package may be as
sembled by first folding in position the lower ñaps
of the corrugated board l2 of the inner container
and then the outer cover 3 at the bottom of the
outer container. The package may then be ñlled
and covered, complete circulation being provided
by'ensuring an air space between the flutings on
the bottom part of the cardboard l2 which places
the cardboard I2 above the bottom of the box.
If it is desired the refrigerant may be placed
in the top of the box above the stiff pad to in
sure that the refrigerant will not come in direct
contact with the material, and in this case, cir
culation will take place about the sides of the
2

inner container and around the bottom between
the flutings and the bottom of the outer con
tainer.
Having now described my invention, I claim:
1. A container comprising an outer cardboard
case, an inner container fitting within the same
and substantially ’filling the space therein, said
inner container having flexible Walls composed
of sheets of paper in face to face relation with
10 a layer of wadding therebetween, a corrugated
said element being closed on four sides, a cor
rugated sheet attached to one end of the en
closed element and forming an end of a bag,
said corrugated sheets being cut at the corners
whereby they may be folded to form the bottom
of the bag.
4. A container of the type described, an in
sulating liner having walls of outer paper ele
ments and inner insulating material, a corru
gated cardboard sheet attached atthe lower end 10
sheet applied about the ends of the walls andl
of the liner on the external side thereof, said
slit to form bottom covers for the inner con
tainer.
2. A container comprising an outer cardboard
corrugated sheet being scored at a point just
above the end of the liner whereby when the
case, an inner ñexible container having an open
top and comprising flexible walls formed of two
sheets of parallelly disposed paper with a heat
insulating layer therebetween, a corrugated sheet
at one end of the walls forming a continuous
20 border about the end thereof and cut at the
corners whereby the sheets may be folded over
to form a bottom of the inner container.
3. In a container of the type described, an
inner liner comprising an element of iiexible outer
25 material and inner heat insulating material,
sheet is folded over to form the bottom of the
inner container, the liner is sealed off at the end.
5. In a container of the type described, an
inner liner composed of two ñexible paper sheets
having insulating material therebetween, means
sealing the insulation in the liner at one end
and a corrugated sheet extending about the other
open end, said corrugated sheet being scored
about said end just above the end of the liner,
said sheet being also cut so that it may be bent
lto form a bottom over the liner.
