WATERLESS ICE BAG Filed March 26, 1935 Qwuwwto b MARGARET EVANS PEARCE.

Patented July 28, 1936 UNITED STATES PATENT OFFICE Application March 26,

1 Claim.

This invention refers to cooling bags for personal use and has among its objects to provide an arrangement which will conserve the cooling medium, such as ice, in it; that will enable the temperature to be kept relatively constant; and in its operation avoid noise and other noticeably objectionable features.

In the use of ice bags, difiiculty is experienced in their use because of the ice melting in same, and in doing so increasing the rate of melting and rise of temperature. The rise of temperature requires, in present methods, a change of bags with its consequent inconvenience to the person using the bag, danger by reason of the sudden removal of the cooling medium, especially in certain types of illness, and reactions tending to induce other effects.

In this invention, the temperature of the bag is kept constant by reason of the ice being dry at all times and free from its melted water. The water is carried off freely and provision is made to avoid the noise of dripping or swishing from the ice-bag water passing into the collector bag or receiver.

In the drawing which illustrates an embodiment of this invention:

Figure 1 is a side view of a cooling bag embodying this invention with portions broken away to indicate the interior construction.

Similar reference characters refer to similar parts throughout the drawing.

In the construction shown I represents a rubber bag or bag of other flexible waterproof material, having an orifice neck 2 with a cap 3 7 arranged for permitting the insertion of pieces of ice into the bag. A flexible tube 4 is attached at a low point outlet 5 of the bag and the tube issufiiciently long to permit it being'oarried or brought to a point some distance from the person using the device. The other end portion 6 of the tube is attached to the cap inlet member 1 in cap 11 of a receiver 8 of rubber or the like, which serves to hold the water flowing from the ice bag. This receiver is provided with the large screwed on cap I! to permit the ready removal of the contents. The cap of the receiver where the tube is attached is arranged with a diverter H formed in the receiver cap and brought to the side of the receiver cap so the incoming water will flow down the walls and avoid dripping into the same. This eliminates the noise that would otherwise occur and its consequent mental irritation to the patient. The receiver cap is provided with an air vent I2 to avoid an air trap in the same. It also has a hook [3 designed to hold the container upright on a horizontal bar or rung of a bed.

1935, Serial No. 13,149

The operation of the device is as follows: The ice in the bag is melted and the water flows down the tube to the receiver where it passes through the diverter down the sides or walls to the bottom. As the water accumulates, the receiver fills up, but the water entering does not drip into it so as to make a noise as it flows into it.

The hook holding the receiver in place holds it upright so the water will not spill and at the same time prevents an accidental tipping of the receiver over by holding the same securely to the bar.

By reason of the bag being waterless at all times when in use, no spilling of the contents can take place on the person, while the worry of such an accident is also eliminated from his mind. The ice, without water surrounding it keeps its solid form longer and does not melt as quickly. It keeps at the same temperature and thus has a more definite and uniform effect on the user and is therefor more desirable for general purposes. The receiver being of rubber or similar materials lessens the opportunity for noise from its contents, breakage and injury.

In Figure 1, the broken away view of the receiver indicates a tube-type diverter which projects down from the cap as indicated.

While two forms of this invention are shown in the drawing, it is not desired to limit this application to these particular forms or in any way otherwise than limited by the prior art, as it is appreciated that other forms and details could be made that would employ the sameprinciples and come within the scope of the appended claim,

What is claimed is:-

A receiver for water draining from an ice bag, comprising in the combination, a bag of flexible material of ball-like form with its upper portion provided with a neck having a screw-thread thereon, a cap screw-threaded interiorly to attach to the screw-threaded portion of the neck having an orifice therein for the attachment of a drain tube insertable therein and an air escape orifice, a diverter plate mounted on the interior of the cap and disposed underneath the first mentioned orifice for diverting water flowing in through the first mentioned orifice towards the side walls of the cap and above the neck of the bag, a drain tube insertable and adjustable in said first mentioned tube, and a clamp for securing the bag to a horizontal rail and to prevent the bag being tipped over, substantially as described.
