This invention relates to devices which are in- -.

By the present inventionit is proposed to pro-
vide a‘ hollow impervious receptacle or container
. having a substantial'quantity of a liquid sealed
therein, which container may be placed in a refrigerator or other cooling; device to freeze the
1o entrapped liquid. This device may then be applied to the body part, or articlev to be cooled, and
being relatively colder than the part- or article
to be cooled, will remove heat therefrom and cool
and maintain cold'the. part orarticle to ‘which
15 it is applied. While devices of this general type
have been-‘heretofore proposed, the novel con,struction of the container according to the pres> ent invention provides considerable advantages

According to this invention, I propose to pro
videa sealed container which is preferably formed
of ?exible, impervious material, preferably rub
her, and'in which is sealed a quantity of 'a'liquid,
such as water, which may be frozen'in such an
ordinarily-available 1' cooling device as a house
hold refrigerator by placing the entire device
within the refrigerator. Such a cooling ap
pliance is illustrated generally in Fig. 1 and it will
be seen that the same may be formed, if desired;
of two substantially ?at open-sided receptacle

may be. united. in the manner described to
thereby provide a hollow container which is
formed of impervious, preferably ?exible ' ma- 25“
Another object is to provide a cooling device
of the type described which will be provided interiorly with means aboutwhich the ice will be
frozen and which, when the device is bent to
30 adapt it to a body part or article to be cooled,
terial. A quantity of a liquid, preferably water,
is put into this container before the sealing oper
ation, this quantity of water being preferably
less than the volume of the container in order to
prevent any possible rupture of the container 30
' will cause the ice to be broken into small and
relatively uniform pieces which will be so disposed within the device as not to present any
bumps or protruding edges.

It is also an object of the invention to provide
-a- cooling appliance of the type described which
may be easily and cheaply manufactured and
‘which will be strong and rugged in construction.
Other objects and features of novelty will be
when the included liquid is frozen.
It willbe ap
parent that the method of inserting the liquid
into the appliance forms no part of the inven
tion, and the liquid may, if desired, be injected
into the container after the sealing operation has 35
been performed. It has been found that the best
results are obtained by removing a substantial
part of the air from the container before sealing
the same, as the presence of a substantial amount

40 apparent from the following description and the of air within the container retards the freezing 4o

What is claimed is:
,
l. A therapeutical device, comprising a con
tainer adapted’ to contain a liquid, and a sponge
rubber member disposed within said container
and lying within the liquid within said container
and adapted to prevent the formation of large
masses of ice within said container when said
liquid is frozen, whereby said device may be easily
bent to ‘a desired shape.

2. A therapeutical device comprising a hollow
container formed .of flexible material and having
a quantity ,of a liquid contained therein, and a
memberclisposed within said container and com-'
easily broken, whereby the ‘coolingappliance ' prising‘a .?exlble mass which substantially fills
the space within said container and which is
60 may be easily and quickly bent to any desired
formcd with a large number of openings through
shape.

. It will be apparent that the'appliance, instead
of being formed oftwo connected members, may
be formed in any other manner and in any de
siredshape. Also, if desired, the twohalves'of
the container may be connected in some manner
whereby they may be separated, ‘either wholly or
partly. If such a construction is employed, the
container need only be ?lled with liquid when it
70 is to be used and at other times the liquid may
be removed therefrom. The appliance may also
be formed of any material other than rubber, as
desired.

While‘ it is primarily intended that the ‘appll-,
76 ance ‘hereinbefore described be employed as a

member and within which the liquid within said
container is received, said member being adapted
to prevent the formation of large masses of’ ice 65
'within the containcr when the liquid therein is
frozen, whereby the device may bev bent to a
‘desired shape.
