HEAT EXCHANGNG CONTAINER Original Filed Jan. 26, 1928 Z0 INVENTOR grunt@ Zt'ndemlf-TL atented May 3, 1932 STATES v BRUNO LINDEMANN, F BERLIN, GERMANY HEAT EXCHANGING CONTAINER Application led Ji'anuary 26, 1928, Serial No. 249,565, and in Germany Ang-ust 25, 1927. Renewed March 24, 1932.
This invention relates to heat exchanging containers, and has particular reference to such devices which are more commonly known as hot water bottles and ice bags.
Prior art hot water bottles have been formed with relatively thin rubber walls with a high degree of heat conductivity, and in order to obviate the necessity for refilling the bottle too frequently, it has been customary to use very hot water and to wrap the bottle in a towel or the like. The towel transmits heat but not enough to burn the patient, and after the water has cooled off somewhat, the towel is removed and the bottle used in its uncovered condition. This procedure is inconvenient to say the least, particularly when the patient or user is an invalid, unable to assist in the wrapping and unwrapping operation.
An important object of the present invention is to provide a heat exchanging container of the above mentioned character with a cushioning wall which will retard the heat exchanging.
Another object of the invention is to provide such a device which will be much more comfortable to the patient when'in use, and which will require filling less frequently than prior art bottles or bags. 30 Another object is to provide such a device of extremely simple construction, neat appearance, and capable of being economically produced.
With these and other objects in view, the invention resides in the novel details of construction and arrangement of parts hereinafter set forth, illustrated in the accompanying drawings and particularly pointed out in the appendedclaims.
In t e drawings- Figure l is a front elevation of a hot water bag embodying the invention,
`Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1.
Referring particularly to the drawings, it will be seen that the improved hot water bag is of the conventional relatively flat form, having a pair of opposed walls and 11h which are suitably secured together at their n edges and characterized by a neck portion 12,
`through which liquid contents may be poured. Said neck portion 12 is, of course, provided with a suitable stopper 13 of any ordinary or preferred form and may also be equipped with the usual handle member 14. The walls 10 and 11b of the bag are preferably formed of thin sheet rubber or Wllcanized fabric, and
in order to retard the heat transference, one
of said walls is provided with a layer 15':L of soft cushioning material, such as sponge rubber, having apertures 20 at suitably spaced intervals, leaving the back wall 11b uncovered at these points.
It will be obvious that the pores of the rubber layer 15a will normally' contain air, and 65 in view of this fact, the bag may be filled with very hot water, without likelihood of rendering the user or patient uncomfortable.
The air in said pores of the rubber acts as insulating means to retard the transference 'I0 of the heat, and after the water has cooled ofi' to some extent, Vthe bag may be turned over, so that the uncovered wall 10 will come directly in contact with that part of the body being treated.
The use of a cushioning layer, of sponge rubber or similar material is not only advantageous in hot water bags, but is equally effective when applied to ice bags. In such devices, the particles of cracked ice em- 86.
ployed, usually cause sharp and Vuncomfortable protuberances on the surface of the bag, which in some cases, are very uncomfortable and in fact, are most unbearable, and it wi be evident that when the bag is coated, as s contemplated by this invention, there will be no such uncomfortable projecting parts.
It is understood that the size and arrangement of said apertures 20 may be varied', in w accordance withv the heat conductivity desired, and it is within the contemplation of this invention to provide a' bag, the same as shown in Figure' 1, with sponge rubber layers on opposite sides, said layers being of diierent thicknesses and having different sized apertures.
In this invention, the heat retarding layers are integral with the water bottle, so as to form a self-contained unit, and are used to 1 0.
form of a relatively directly transfer heat without any poultice action.
From the foregoing, it will be evident, that a novel heat exchanging container has been provided, which is capable of being economically produced, and which will be of neat appearance and durable in service. The invention is susceptible of further modiications in the details of construction and the right is herein reserved to make such changes as fall within the scope of the appended claims without departing from tne spirit of the invention.
Having thus described my invention, what I claim is g 1. A heat exchan g container in the@ fit1 bag of sheet rubber the outer surfaces of the opposite sides of the bag being provided with layers of sponge rubber, said layers of sponge rubber being apertured at spaced intervals to expose the bag Walls proper.
2. A heat exchanging container in the form of a relatively fiat bag of sheet rubber the outer surface of at least one side of the bag being provided with a layer of sponge rubber permanently secured to the bag, said layer of sponge rubber being apertured at spaced intervals to expose the outer surface of said side therewith.
3. A heat exchanging container in they form of a Water-tight receptacle having a relatively flat side wall, a dry cushioning structure joined at one side to the outer face of said side Wall and otherwise exposed for direct contact with the body of a person, said structure comprising longitudinal and transverse walls disposed in intersecting relation and adapted of themselves to retard transference of heat from said side wall and be# ing of a dry porous character, said intersecting walls forming open pores adapted to entrap air therein to,V act `further as heat retarding means interlaying the structure and adjoimng the body of the person when the cushioning structure is placed in direct contact therewith.
In testimony that I claim the foregoing as my invention, I have signed my name hereto.
BRUNO LINDEMANN.
