As is well known, it is the common practice to
feed babies from various types of glass bottles
A further object is to provide a nursing bottle
of the character referred to whereinthe container
provided with suitable rubber nipples in accord
may be placed in the holder without touching the '
upper edge of the container,v thus preventing any OI
6 ance with the type oi bottles employed. These
appurtenances are commonly more or less
. sterilized by boiling them in Water. It is a
matter of scientific fact that perfect sterilization
of the conventional glass bottles and rubber
nipples cannot be effected, and while infant
mortality has dropped quite materially due to
improved methods of handling milk and in exer
cislng care in the handling of nursing bottles,
there is still room for substantial improvement,
particularly because of the impossibility of per
fectly sterilizing nursing bottles.
There are other disadvantages involved in the
use of conventional glass bottles and rubber
gontamination from. coming in contact with the
ood.

A further object is to provide a novel type of
disposable container which is adapted to be
packed singly or nested in groups and sold in 10
sterile packages.

A further object is to provide a relatively rigid

Referring to Figures 1 and 2, the numeral II
designates a sleeve or holder which is preferably
formed of metal or other relatively rigid mate
rial. For example, the holder may be formed of
stainless steel or other metal, or it may be
formed of a molding composition. The holder
or sleeve is preferably cylindrical throughout its
length and open at both ends, and the upper end
of the sleeve is turned outwardly to form a hori~
zontal flange I2. While the thickness of the
material of the sleeve II is somewhat exag
20 gerated, particularly in Figures 5 and 6, atten
tion is invited to the fact that such material,
and particularly the portion of the sleeve form
ing the flange I2, is formed relatively thin so
that the upper edge of the flange I2 is relatively
25 sharp, for a purpose to be described. The upper
end portion of the sleeve may be longitudinally
slit as at I3 to provide a substantial degree of
radial resiliency, for a purpose to be referred to
later.
30
A container I4 is adapted to be arranged in
the holder II in the manner shown in Figure 2.
Such form of container preferably is tapered
to decrease in diameter toward its lower end, and
. the container is provided with a bottom I5 spaced
from the lower extremity of the container to form
a ñnger engaging flange I6. At its upper end
the body of the container I4 extends outwardly
in the form of a horizontal flange I1, and then
downwardly to form a depending annular flange
40 I 8 which obviously is spaced from the body of the
the holder 2l. The container 24, as distin
guished from the container I4, may be cylin
drical as clearly shown in Figure 4. The bot
tom 25 of the container 24 is also spaced from
the lower end of the body of the container to form
a finger engaging flange 26. The upper end of
the container 24 is formed in the same manner
as the upper end of the container I4, being pro
vided with an outstanding annular flange 21 and
a depending cylindrical flange 28, spaced from 10
the body of the container and adapted to receive
the flange 23 therewithin, as shown in Figure 4.
Upon the placing of one of the nipples I9 in po
sition, the flange 28 will be turned inwardly in the
manner shown in Figure 6.
While it is preferred to employ a sleeve as a
holder for the container, as shown in Figures 1
to 4 inclusive, such sleeve may be dispensed with
and a simple holder of the type shown in Figure
7 may be employed. Such holder comprises a
sleeve portion 29, which is relatively short, and
such sleeve portion is provided at its upper
extremity with an outstanding horizontal flange
3U. This flange is identical with the flanges I2
and 23 of the forms of the invention previously 25
described, and the sleeve or body portion 29
corresponds to the upper end of the holder 2I,
shown in Figures 3 and 4. The form of the
invention in Figure 7 is shown in conjunction
with one of the containers 24.
In the forms of 30
the invention previously described, the holder is
retained for permanent use while the containers
are .used only once and then discarded.
In the
form shown in Figure 7, the holder is in the form
of a small ring of inverted L-shaped cross-sec 35
tion which may form a part of the container,
as purchased, and may be discarded therewith.
As previously stated, the holder 2| as shown
in Figures 3 and 4, may be provided with the
slots 22 through which the height of the liquid 40
in the container may be determined. To facili

metrically opposite longitudinal slots 22, as shown . in one of the holders II wherein the slits I3 are
in Figures 3 and 4, to permit the quantity of

end of the holder 2| is provided with a flange 23
which is preferably identical with the flange I2
previously described.

As clearly shown in Figure 9, the upper end of
the container 32 is smaller in diameter than the
corresponding portion of the holder, an annular
space 33 thus being'provided to permit the con 75
ananas
traction of the upper end of the holder for a
purpose to be described. 'At its upper end the
container extends outwardly in a horizontal
flange portion 3i and then downwardly in a
short cylindrical portion t5 which surrounds the
outer edge of the iiange i2. Below the cylindri
cal portion 35, the material of the container ex
tends horizontally inwardiy as at 36, the edge
of the material engaging the surface of the con
tainer when the upper end of the latter is in its
normal shape. The width of the annular space
33 is at least equal to the width of the flange i2
to permit the outer edge of the latter to clear
the inner edge of the flange 36 when the upper
end of the holder is contracted.
¿
The operation of the form of the invention
shown in Figures i and 2 is as follows:
Because of the tapered construction of the
containers it, these containers may be nested
20 whereby they may be sold in groups in a sterile
carton or container of any desired type. For
example, six of the containers iii may be nested
in a carton or the like to provide a fresh con
While the
' taincr for each of a. day’s feedings.
25 tapering of the containers facilitates the nesting
thereof, it will be obvious that they need not be
nested but may be sold individually packed.
The containers Id are sold or dispensed in a
perfectly sterile condition and may be handled
30 without the fingers coming into contact with the
interior of the container or the exposed surfaces
of the flange I‘I or I8. The holder II, however,
need not be sterile, since it obviously does not
come into contact with any of the surfaces of
the container just referred to. If the containers
are sold in nested groups, it is preferred that the
proportions of the containers be such that the
flange- portions of successive containers will be
spaced apart a sufficient distance to permit the
40 outside of thè body' of’ each container to be
grasped in the fingers without contacting the
upper face o'f the fiange I 'I of .the next lower con
tainer. For example, the bottom I5 maybe
i 3
plied. In connection with the previous filling of
the container, it will be noted that several con
tainers may be kept in arefrigerator with an in
dividual feeding in each container and with the
upper end of the container closed by a suitable
cap, such as the caps now commonly employed
as closures for commercial milk bottles, with de
pending skirts overhanging the upper extremi
ties of the bottles. Such caps, in perfectly sterile
condition, may be sold in packages with the con
tainers or in sterile packages' wholly separate
therefrom.
It is preferred that the containers i ii be made
of waterproof land heat-proof material. Such
material permits the previous ñlling of the con
tainers and the storage 'of the filled containers
in a refrigerator. Upon the placing of the con
tainer in the holder, therefore, the bottom of the
latter is adapted to support the device in an up
right position to be heated to the proper tem
perature in a container of water. The inside in
dicia t2 facilitates the filling of each container
since the indicia may be viewed through the top
of vthe container while the latter is being filled.
Assuming that the container is in position in
the holder and filled with food in the proper
amount, the breast and nipple I9 may be placed
in position ready for the feeding. The down
ward pressure exerted in placing the breast and
nipple in position and the inward radial force 30
exerted due to the elastic nature of the nipple
causes the outer relatively sharp edge of the
flange I2to cut into or embed itself in the portion
of the container flange I8 against which it con
tacts. The lower annular portion of the breast
and nipple contracts beneath the iiange I2 and
forces the lower portion of the flange inwardly to
the position shown’in Figure 6. After the parts
have been thus assembled, the device is ready for
40
use.
Upon the completion of the feeding,.the breast
and nipple may be removed,~and its removal tends
further to cause the edge of the fiange I2 to embed
itself into the flange I8. The turned in portion
of the flange may be pulled outwardly to facilitate
45 tremity of‘the container to support the lower ex

One of the containers, with the body vportion stantially destroys the container and prevents re.
50 thereof grasped between the fingers, may be use thereof. Thus it is necessary to’use a new and
spaced a sufficient distance from the lower `ex
dropped into the upper end of the holder II. It
_is unnecessary for the person handling the de
vice to press upon the upper face of the flange
sterile container for each feeding.
,
In the form of the invention shown in Figures
3 and 4 a cylindrical container 24 has been illus
trated. although it will be apparent that one of
the tapered containers I4 may be employed. The
cylindrical container 24 is preferably slightly
smaller in diameter than the holder 2i to facili
tate the insertion of the container in the holder.
While the flange 26 is of such diameter as to pre
vent the grasping thereof between two fingers, as 60

I1 to properly position the container within the
55 holder. It will be noted that the lower end of
the holder is entirely-.open and unobstructed in
any way, and the thumb and foreiinger of one
hand may be inserted into the holder to grasp
. _the lower end of the flange I6 and pull the con
60 tainer downwardly into the holder. The slits I3
vprovide the upper end of the holder with a sub
4

other suitable material, and transparent or semi
transparent material is preferably employed ln
order to permit the height of the level of the liquid
in the container to be more readily determined.
The placing of the slots 22 at points spaced a
substantial distance apart permits light to pass
across the container between the slots, thus per
mitting the height of the liquid in the container
to be very readily determined.
It will be noted that the holders previously de
10
scribed greatly facilitate the handling of the con
tainer. For example, as previously stated, these
holders facilitate the heating of the food in the
containers, and facilitate the supporting of the
15 containers in upright position on any flat surface.
However, the use of the holders of the device
shown in Figures 1 to 4 inclusive is not essential,
The principal feature of the holder lying in the
provision of the rigid flange I2 for the purpose
20 described. Therefore, instead of a long cylin
drical holder, only a relatively short ring need be
provided, as shown in Figure 7. The relatively
short sleeve 29 and its flange 30 provide the nec
essary rigid support for the flange 21 of the con
25 tainer, and the outer edge of the flange 30 per
forms the same function as the flanges I2 and
the container. The removal of the container
may take place without contracting the upper
end of the holder, in which case the flange I2
likewise substantially damages the flange 36 of
the container.
From the foregoing it will be apparent that the
device is inexpensive and that it embodies numer
ous advantages over other structures.
For exam
ple, its use is less expensive than the use of glass
bottles; it savesthe time and fue‘- employed iu
sterlizing glass bottles; it saves the hands from
possible injury due to broken glass and to burn
ing incident to the sterilization of glass bottles,
etc. Most important, however, is the great ad
vantage of perfect sterility of the device, the con 15
tainers being perfectly sterilized before being
packaged whereas perfect sterilization of glass
bottles is impossible under ordinary conditions.
As previously stated, the food containers may
be made of paper or any other desirable rela
tively cheap disposable material. ' It will be under
20
stood that the material employed in the making
of the containers, and at least with respect to the
portions of the several types of containers which
are engaged by the flanges at the upper ends of
the holders, is relatively soft so as to permit the
outer edgeof the flange I2, 23 or 30 to readily
embed itself to a substantial extent in the over
23 of the forms of the device previously described.
It will be noted that the holders II and 2| are
not in any sense containers, but merely hold and
30 support either of the types of containers described.
For simplicity and economy in manufacture, the
hanging flange of the container. Accordingly the
removal of the containers, particularly in view
of the crimping of the overhanging flanges of
holders I I and 2l are preferably cylindrical so as
the containers beneath the flange of the holder,
to provide substantial stability for supporting the
container in an upright position. However, if
so damages the container as to render it unfit
for further use thus requiring the use of a new
desired, the lower ends of the holders may be pro
vided with any suitable means for assisting in
container for each feeding. Of course, in the
form of the invention shown in Figure 9, the
flange 36 will be preformed for arrangement be
neath the ñange I2, and accordingly will not be
crimped in the assembly of the parts, but the
flange 36 will be substantially damaged upon the 40
removal of the container, in the manner previ
holding them in vertical position, although such
means has been found to be wholly unnecessary.
The holders II and 2| are intended for perma
40 nent use as previously stated, while the containers
are intended to be sold in sterile packages. The
containers I4 are adapted to be nested to be sold
in groups, although it will be apparent that nest
ing is not possible with the cylindrical container
24 shown in Figure 4. When the holder of the
type shown in Figure 7 is employed, the simplicity
and cheapness of manufacture of the holder per
mits its embodiment with each of the containers.
In such case, the holder and container both will
50 be discarded after use, or the holder may be made
separate from the container and retained for
permanent use.
In using the form of the invention shown ln
Figure 9, the upper end of the holder will be con
CI Ul tracted, when the container is dropped into the
holder, to move the inner surfaces of the upper
end of the holder into contact with the outer sur
face of the body of the container. Under such
conditions, the outer edge of the flange I2 will
60 clear the inner edge of the flange 36, whereupon
the container will drop into position "with the
flange 34 supported on the flange I2.- 'I’he upper
end of the holder then may be released to expand
to its normal position; in which case the flange
I2 will move outwardly into engagement with the
inner surface of the flange 36, as shown in Fig
ously described.
It is to be understood that the forms of the in
vention herewith shown and described are to be
taken as preferred examples of the same and that
various changes in the shape, size and arrange
ment of parts may be resorted to Without depart
ing from the _spirit of the invention or the scope
of the subjoined claims.
