of paper or similar material, one of the major
2o items of expense is the stock used. Consequently,
with economy in manufacture being an essential
in this line of endeavor, it is desirable to eliminate
wastage of stock, and to use as little stock as pos

As shown on the drawing:

For purposes of illustration, I have selected an
embodiment of the present invention in the form
of a flat bottom paper drinking cup, or ice cream
cup, of a character which _is usually disposed of
after a single usage, although it will be apparent 25
that the invention is not limited strictly to the
illustrated container, but may include containers
like, a slightly heavier stock is used. 'than is the
for other purposes.

The illustrated container or drinking cup in

Ac'
30 cordingly, the importance of using as little stock
>as possible with ñat bottom containers is greatly
magnified.
'
With the foregoing in mind, it is an important
object of the present invention to provide a flat
_
cated conical shape as illustrated, having a curled ‘
drinking rim 8 at the mouth end thereof. The
opposite end of the tubular body portion 'i is
closed by a bottom member 9 having a depending
?lange IB which is, >in this instance, adhesively 35

containers of similar types heretofore known.
It is also an object of this invention to provide
45 a container made of a plurality of initially sep
arate blanks wherein less stock is used than is
the case with containers of similar types hereto
fore known, without any lesseningof the capacity
of the resultant container.

.
Also a feature of the invention is the provision
of a new andnovel method of making a container
'
-of the character described.

While some of the more salient features, char
acterlstics'and advantages of the present inven
55 tion have. been above >pointed'out, others will be
It will be distinctly noted that the turned margin
I2 terminates a very material distance below-the
bottom proper 9, and the annular spacebetween
the end of the turned margin i2 and the bottom -
proper 9 represents the amount of paper stock 45
saved in the manufacture of this container:
The body portion of the container is made ,
from a _blank 'la shown in Figure 3. 'This blank,
.prior to its formation into the container body, is
preferably provided with a‘suitable adhesive I3 50
along one of the side margins of the blank and,
another application I4 of adhesive is provided
along the bottom margin of the blank.l It will

the lower margin of the flange III is also rolled
slightly inwardly as indicated at I1, concentri
cally with the margin I6. The rolling action
provides a relativelysmooth base for the con
lower edge of the blank, leaving a v’margin I2a
, preferably free from adhesive which, in the com
pleted container, is the turned margin I2 men
tioned above.
In the making of the container, the body blank

between the body and bottom, but it will be
noted that when the slight roll is used. less body
material is necessary than with the construction
‘Ia` is ñrst cut to size and provided with the ad
hesived portions I3 and I4 as above described.
This blank is then formed into a tubular body
portion with the adhesive I3 uniting overlapped
`
10 marginal portions, as indicated at I5 in Figure
previously described.
'
_
In Figure 6, I have shown a construction which 10
effects a still greater saving of stock. The bot
body 1 of the container in
proper shape. Either during the formation of the
blank ‘Ia into the tubular body or thereafter as
may be deemed most feasible, the bottom member
tom member, together with its flange, is joined
l 2 to maintainthe
to the body in the manner above described. In
this instance, however, a lower marginal portion
I8 of the body is merely turned inwardly so as 15
to overlie the lower edge of the flange I0 on the
9 is placed in position sufficiently far inside theÁ
tube so that the adhesive I4 will unite the flange
I0 of the bottom member and the container body.
If so desired, a slight ironing or pressing action
may be provided to insure the proper adhesion.
20 The' next operation is to turn inwardly the non
bottom member and, in this instance,.the turned
margin I8 effects little or ‘no engagement with
adhesived margin I2a. of the blank to provide the
turned margin I2 of the container. This latter
operation not only effects a better union between
the container body and the bottom member, but
also provides a relatively smooth base for the
25
container as a whole.
'
In containers of this type as they were usually
manufactured heretofore, the adhesive III was
brought substantially to the lower edge of the
blank,
which blank was longer than-that illus
30
trated herein. When the bottom margin of the
blank was turned inwardly, this margin extended
substantially to the bottom proper 9 and was
adhesively secured to the inner face of the flange
I0, necessitating in most instances an ironing
35 operation to insure the proper adhesion. It will
be noted that the efficiency and satisfactory op
eration of the present container is not detracted
from in any material degree by the terminating
of the flange I2 a relatively considerable dis
40 tance below the bottom proper 9, thus saving
that amount offpaper stock, and by not adhesive
ly uniting the turned margin I2 to the inner
face ofthe flange I0, although, if so desired,
such adhesive union could be :readily effected in
45 the present invention. When quantity manu
facture is considered, it will at once be apparent
that the saving of stock effected by the present
invention is a very substantial item.
-
In Figure 5, I have shown a slightly modiñed
50 form of construction which results in a still
greater saving of stock. In this instance, sub
stantially the same container body is provided,
but this body is slightly shorter than as previ
ously described. The bottom member 9 with
55 its flange I0 is adhesively secured to thev body
in the same manner as indicatedat II. How
ever, the lower marginal portion' of the body
is slightly rolled inwardly as indicated at I6, and
any but the direct lower edge of the flange.
Accordingly, the turned margin I8 need not be
quite as long as the margin I6 just previously
described.
i
'
From the foregoing, it will be apparent that
I have provided a highly eñicient and satisfac
tory -container which results, in its manufac
ture, in a material saving of stock, without any
detraction from the efliciency of the container
or any lessening of its capacity. It will also
be noted that a container manufactured in ac
cordance with the principles of this invention
and in accordance with the novel method set
forth herein eliminates certain expensive manu
facturing operations, and the making of the con
tainer may be accomplished with great facility
and in an economical manner.
_
I am aware that many changes may be made
and numerous details of construction may be
varied through awìde range without departing
from the principles of this invention, and I,
therefore, do not purpose limiting the patent 40
granted hereon otherwise than is necessitated by
the prior art.
I claim as my invention:
_ A container of the character described made
fromv a body blank and a bottom blank, the body 45
blank having adhesive adjacent a side edge to
join overlapping marginal portions to .provide
a tubular body, and said body blank having ad
hesive along the bottom edge but spaced from
this edge to leave an edge part vfree of adhesive,
a bottom blank having a depending flange dis
posed in the tubular body with the second said
adhesive joining the body and flange, and the
lower body edge free from adhesive being turned
inwardly so as to-be crimped against the edge
of said flange and~ the extremity thereof termi
nating beyond said crimped engagement and a
material distance below the bottom proper.
