I , 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 20 ‘ Fig. 4 is a view taken on the line 4-4’ of Fig. 3, and Fig. 5 is a view taken on the line 15-1-5 of Fig. 1 and showing a further form which the inven~ tion may take. ‘ 5 ' 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 members I, 2 disposed in face-to-face engagement and united by vulcanizing or otherwise attaching 5 v10 f 15 7 over prior art constructions. ' It is an object of this invention to provide a their meeting edges. As illustrated in Fig. 1 these members may have formed, about the free 20 cooling appliance of the type described which will edges thereof, ?anges 3, 4 which abut when the be so constructed as to permit it, when the en' trapped liquid is frozen, to be bent to conform to any part or article which it is desired to cooland '25 to which the cooling device may be applied. two members are brought together‘ and which 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. ' 35 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 annexed drawing, it being clearly understood, of the water therein. however, that the invention is not limited in any One form which my invention may take is il way by suchv description and drawing, which are ‘lustrated in Fig. 2 and, referring to this ?gure, illustrative only, or otherwise than by the ap- it will be seen that means are provided for pre 45 pended claims. . venting the formation of a solid mass or sheet 45 Referring to the drawing, in which similar reference numerals refer to like parts, Fig. 1 is a perspective view of a cooling-appliance which may be formed according to the 50 present invention; Fig. 2 is a cross sectional view taken on the line 2--2 of‘Flg. 1 and showing one form which the invention may take; _ vFig. 3 is‘ a- view, similar to'Fig. 2, and showing 55 a modi?ed form of the invention; 5 of ice within the receptacle. Such means com prise,» in this form of. the invention, a plurality of posts or studs 5, which are preferably formed integrally with and of the same material as one of the outer walls of the receptacle, and which 50' extend from such wall toward the opposite wall and into the interior of the" container. These posts or studs may be of any desired thickness or ‘ shape and, inthis form of the invention, are of ‘ such a length that they extend approximately to 55 " i I _ 9,190,013 1 the opposite wall of v‘ the'icontainer'and may be cooling device, ,it Mil be apparent that it may” regularly ‘or irregularly spaced on the wall from - be used as a heating pad by applying heat there! which they‘ extend.

This sponge, ‘rubber member is saturated with a liquid, such as water, preferably before being sealed within '50 the appliance. When required, the cooling ap pliance so formed may be placed within a re frigerator or other cooling device and the en, trapped liquid frozen.

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.

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 out whichlcommunicate with the exterior of said 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. ; -_ ‘ 3.
