PROVISIONAL SPECIFICATION.
Improvements in and connected with Rubber or like Flexible Bottles
for containing Hot Water, Ice, or other Substances.
A communication from abroad by JoHN F. MORRILL, of Boston, in the County of
Suffolk, State of Massachusetts, United States of America.
I, PHILIP MIDDLETON Justice, of 55 and 56, Chancery Lane, in the County of
Middlesex, Fellow of the Chartered Institute of Patent Agents, do hereby
declare the nature of this invention to be as follows:-
It is well known that in the use of the ordinary rubber hot water bottles or
bags, which are constructed of only one thickness of rubber or other flexible
material, much danger of burning the skin of the person to which it is applied
is encountered, should the water with which the receptacle is filled be too hot,
and from the peculiar construction of these bottles, which offer a large radiating
surface, the contents rapidly cool; further owing to bursting scalding is not
infrequent. Where this same form of receptacle is employed as an ice compress,
it is filled with cracked ice, and as the bag is bound tightly on to the person of
the user, the ragged or sharp edges of the ice frequently hurt and also prevent the
whole surface being engaged effectively with the flesh. Numerous expedients have
been employed to overcome these objections, as for example, covering the bag or
compress with felt or similar material which will not readily conduct heat or cold.
But these methods are impracticable and inefficient. The present invention is
designed particularly to overcome these objections, and to carry out the objects it
is proposed to take a bag or bottle of rubber or other suitable flexible material for
containing liquid or cracked ice. This bag is of the usual rectangular form, and
is provided with a filler nipple closed by a screw cap or plug surrounded in the
usual manner by a flaring rubber guard. As thus far described the device is of
the ordinary construction."
According to this invention in addition to such ordinary bag or bottle it is
proposed to employ an outer or enclosing air tight bag, entirely surrounding the
main bag and having its walls connected thereto by stays of tape or other suitable
material to prevent distortion and the surface of the inner bag from engaging that
of the outer
An air tube passes through the outer wall of the outer bag, whereby it may be
inflated, a clamp or other device closing said tube and preventing the escape of air.
The outer or enclosing case may be corrugated on one surface to fit portions of the
figure, as the neck or forehead, and said casing may be provided at its ends with
attaching straps.
The invention is not limited to constructing the device of any particular shape,
or arranging its parts in any especial manner, a salient feature of the invention
being a liquid-tight containing bag or receptacle enclosed in an air containing
casing, whereby said inner receptacle is entirely surrounded by an air cushion.

ing the wearer, and the air space will also prevent danger of burning from
contact with the inner bag, should it be over-heated while the efficiency of the
device is in no wise lessened, the air becoming heated or cooled as the case
may be.

Improvements in and connected with Rubber or like Flexible Bottles
for containing Hot Water, Ice, or other Substances
A communication from abroad by JoHN F. MORRILL, of Boston, in the County of
Suffolk, State of Massachusetts, United States of America.
I, PHILIP MIDDLETON JUSTICE, of 55 and 56, Chancery Lane, in the County of
Middlesex, Fellow of the Chartered Institute of Patent Agents, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and to the following
statement, reference being had to the accompanying drawings forming a part of this
specification, in which: -
Fig. 1 is a plan view of one form of the improved flexible bottle, a portion
of the nipple guard being represented as broken away.
Fig. 2, a vertical transverse section of the same;
Fig. 3, a vertical longitudinal section shown as broken away; and
Fig. 4, a plan view representing the form of bag or bottle particularly adapted
for use as an ice compress.
It is well known that in the use of the ordinary rubber hot water bottle or bag,
which are constructed of only one thickness of rubber or other flexible material,
much danger of burning the skin of the person to which it is applied is encountered,
should the water with which the receptacle is filled be too hot, and from the
peculiar construction of these bottles, which offer a large radiating surface, the
contents rapidly cool. In the case where this same form of receptacle is employed
as an ice compress, it is filled with cracked ice, and as the bag is bound tightly
on to the person of the user, the ragged or sharp edges of the ice frequently hurt
and prevent the whole surface being engaged effectively with the flesh. Numerous
expedients have been employed to overcome these objections, as for example,
covering the bag or compress with felt or similar material which will not readily
conduct heat or cold. But these methods are impracticable and inefficient. This
invention is designed particularly to overcome these objections, and in carrying it
out it is proposed to use means which will be readily understood by those conversant
with such matters, from the following explanation.
In the drawing, A, represents a bag or bottle of rubber or other suitable flexible
material for containing liquid or cracked ice. This bag is of the usual rectangular
form, and is provided with a filler nipple, f, closed by a screw cap or plug, g,
surrounded in the usual manner by a flaring rubber guard, h. As thus far
described the device is of the ordinary construction. According to the present
improvement it is proposed to form an outer or enclosing air tight expansible
bag, B, entirely surrounding the main bag, A, and having its walls connected
thereto by stays, i, of tape or other suitable material to prevent distortion, and the
surface of the inner bag from engaging that of the outer.

page_text: And air tube, k, passes through the outer wall of the bag, B, whereby it may be
inflated, a clamp, m, closing said tube and preventing the escape of air.
In Fig. 1 this tube is represented at the bottom of the bag, but a tube, p, adjacent
to the nipple, f, may be arranged as indicated by dotted lines in Fig. 1, with an
air valve or cap, q, disposed inside the guard h. In fact any suitable means may
be employed for inflating the outer bag or casing. This outer bag may be made
of any material which will hold air, it is preferable to employ rubber, or the same
material as the inner bag is formed of.
The ice compress, H, shown in Fig. 4 does not differ in construction in any
material degree from the form just described. The outer or enclosing casing, B,
may be corrugated as at t, on one surface to fit portions of the figure, as the neck
or forehead, and said casing may be provided at its ends with attaching straps, v.
As this form is particularly adapted for use with ice the filler nipple, w, entering
the inner bag is enlarged to facilitate filling with a solid substance. This nipple
is closed by any form of stopper or plug, a.
It is not intended to limit the construction of the device to any particular shape,
or arranging its parts in any special manner, a salient feature of the invention being
a liquid containing bag or receptacle enclosed in an air expansible casing, whereby
said inner receptacle is entirely surrounded by an air cushion. It will be seen that
this cushion will serve to prevent the ice from hurting the wearer, and the air space
will also prevent danger of burning from contact with the inner bag, should it be
overheated while the efficiency of the device is in no wise lessened, the air becoming
heated or cooled as the case may be.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1st. The herein described rubber liquid-containing receptacle provided with the
filler-nipple, in combination with an expansible casing entirely enclosing said
receptacle, and leaving an air-space between; and an air-valve for inflating said
casing, substantially as described.
2nd. The herein described flexible bottle comprising a flexible bag, A, provided
with a filler-nipple f; an expansible casing, B, entirely enclosing said bottle;
flexible stays, i, connecting the walls of the casing to the walls of the bottle,
whereby their relative position is maintained, and an air-valve for inflating and
deflating said casing, substantially as specified.
Dated this 10th day of September 1898.
