8 Claims.

This invention relates to water bags, and more particularly to a receptacle designed to be watertight which may be employed as a hot water bag, but which will at the same time have a neck or mouth of sufiicient size so that the receptacle may readily be filled with pieces of ice, and which will be provided with a connection for a syringe tube so that it may also be used as a syringe. Certain features of our invention, however, are desirable for use in devices for one or more of the purposes above named, and are not necessarily restricted to a bag or receptacle which is used for all of the three stated objects.

It is more or less common to combine a hot water bag and syringe into a single device, that is, to provide a rubber bag or similar receptacle with a filling opening which may be closed against leakage, and also with a connection for a syringe tube which may also be closed when it is desired to use the device as a hot water bottle. However, such a receptacle has not been well adapted for use as an ice bag, owing to the fact that the filling opening is usually of relatively small size and will not receive sufliciently large pieces of ice. If the filling opening was of large size, difilculty was encountered in closing this opening tightly against leakage, or, if a screw plug was employed, the bag would be unwieldy and awkward or uncomfortable to use.

The present invention, however, has for one of its objects the provision of a three-in-one receptacle which may be used as a hot water bag, as an ice bag, or as the receptacle for a fountain syringe.

Another object of the invention is the provision of a receptacle formed of waterproof material so that it may contain water, which is provided with a relatively large filling neck through which cracked ice may be inserted, and which also embodies means for effectively closing said filling neck when the bag or receptacle is in use to prevent leakage of the contents.

Another object of the invention is the provision of a bag or receptacle of the character described, which is provided with a filling neck of relatively large size and of flexible material, whereby this neck may be folded within the outline of the receptacle itself and the latter closed over the neck to conceal the neck from view.

Another object of the invention is the provision of a water-tight receptacle which when closed will have a smooth exterior outline, and will be provided with no projecting necks or tabs such water bottles.

A still further object of the invention is the provision of a water-tight receptacle having a filling neck, and means for closing said neck against leakage, and also being provided with a secondary closure within which the neck may be contained, so that the latter is concealed and lies within the regular outline of the receptacle when the secondary closure is in closed position.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

Fig. 11 is an enlarged section on line I I--ll of Fig; 1.

To illustrate a preferred embodiment of our invention, we have shown a waterproof bag or receptacle l0 which maybe and preferably is made of rubber, as is usual with hot water bags of this character. As shown, for example, in Figs. 4, '7 and 8, the bag I0 is open across its entire top. and for a short distance down each side. At the edges formed by this opening a fastening means is provided to secure the edges together. As shown, this means may be in the form of the ordinary zippers or hookless fasteners H, which may be mounted upon tapes i2, the tapes in turn being secured to the rubber walls of the bag. The usual slider I 3 is provided to effect the opening and closing of the fasteners.

The closure just described may be termed the secondary closure of the receptacle, as this does not form the water-tight or leak-proof closure for the watercontaining portion of the device. That closure will, however, now bedescribed. A

' filler neck It is provided whiclfle'ads into the inthe filling neck II when the latter is in the posisecured to the wall by the projecting partition portions I1 and I8, shown more particularly in Fig. 7.

It will be seen with reference to Fig. 4 that the neck I4 is relatively long, and when in extended position, as when it is ready for filling, as shown in Figs. 4 and 5,'projects from the opening at the upper end of the receptacle III through the closure II. This neck forms the primary closure of the water-tight receptacle, and, as wil be hereinafter explained, is of flexible material and adapted to be folded or rolled andtucked within the upper portion of the bag l so that it will not only be leak-proof but will be concealed from sight.

It will be noted, of course, that thelower end of the neck I 4 is some distance below the upper end of the bag l0, so that considerable space is provided between the shoulders or projections l1 and [8, as shown in Fig. 7, and the top closure of'the bag, thus providing a space in the form of a pocket within which the neck Il may be disposed when folded. In order that the folding operation may be effected conveniently. and in order that it may be locked in place after being folded, a lock bar is provided which is shown more especially in Fig. 9. This lock bar consists of a pair of end members ['9 and 20 provided with angularly disposed portions 2| and 22 forming hooks in connection with the portions I9 and 20.

The members Ill-and 20 are joined by a fiat bar 23, and also extending between them is a rod 24 which may be inserted through a tubular boss 25 carried upon the side of the neck It. This rod may be conveniently pased through the boss or sleeve 25, and thereafter secured by rivetingto the members I! and 20 in order to secure the lock bar to the neck. The position of the lock bar when secured in place is shown in Fig. 2, from which it will be seen. that the bar 23 rests against the wall of the neck above the tubular boss or sleeve 25, and that the end members I 9 and 20 lie just beyond the side edges of the neck H, as the length of the bar 23 and rod 24 correspond substantially with the width of the filling neck.

0n the inner surface of the walls of the receptacle l0 adjacent the upper end thereof and within the space above the: members l and IS a pair of hooks or catch members 26 are provided, these members being preferably formed of rubber and being molded upon the wall of the bag or receptacle III, which is of the same material. As shown in Fig. 4. one of these hooks or catch members is provided adjacent each side edge of the bag. Upon the opposite wall of the bag and located substantially opposite but slightly above the members 28 are a pair of stop members 21, which may also bev molded integrally with the bag wall. The members 26 and 21 are designed to cooperate with the lock members 19 and 20 to hold the neck in closed position within the mouth of the receptacle and below the closure I2.

The bag is filled with water or ice through tion shown in Figs. 2, 4 and 5. It being desired to close the bag, the members I! and 20 are grasped between the fingers and the lock bar is turned downwardly away from the observer, as

shown in Fig. 2, or to the right, as shown in,

Fig. 5, so as to roll or fold up the flexible neck l4. As shown, it is designed that the lock bar be given one and a half complete turns, or three half turns, at the end of which movement the neck will be folded or rolled into the position shown in Figs. 7 and 8, and the hook members originally at the upper edges of the members I! .and 20 will lie in reverse position at the lower edges of these members. so as to engage below the hooks or catch members 28, as shown in Fig. 8. The upper ends of the members I! and 20, as

"--.shown in this figure, will abut against the stops 21, and thus this member will be eflectively held in position and the neck M will be prevented from unrolling. The walls of the neck will be tightly pressed together in this position so that there will be no danger of leakage regardless of the position in which the bag may be, and the folded neck. as apparent from Figs. 7 and 8, will lie within the upper portion of the receptacle below the closure I2, so that the latter may be closed and the folded neck completely concealed from view. The bag willthen have the appearance shown in Figs.'1 and 6.

In order that our device may be employed as a fountain syringe aswell as a hot water bag and ice bag, we have provided in one of the walls a means for connection with a tube, which connection will lead to the interior or chamber of the bag. As one means of accomplishing this result, there is formed upon one of the walls of the bag, and in this instance adjacent the upper end thereof, a valve housing '28 within which is mounted a valve plug 29. This plug is provided with a laterally extending flange 30 adapted to seat in a corresponding recess in the body 28 to hold the plug in place, and is also provided with an opening 3| extending inwardly from the exterior thereof part way through the valve body. From the bottom of this opening to the inner end, the valve member is split longitudinally into two parts, as shown at 32.

A nipple member 33, connected at the end of a rubber syringe tube 34 of the usual form, is designed to be inserted through the opening 3! and between the inner portions of the valve 23 through the split 32. As shown, for example in Fig. 10, this will cause the inner end portions of the valve member to be spread apart so that the nipple 33 will communicate with the interior of the receptacle. As will also be apparent from Fig. 7, when the nipple is withdrawn, the portions of the valve body on opposite sides of the split 32 will return to tightly abutting relation so as to effectively seal the valve opening against leakage. In another aspect there is provided a means automatically operable by the insertion of a nipple-equipped syringe tube into a socketed' portion on or associated with the bag wall, for

opening communication between the bag interior and the passage in the tube.

Although the invention in all of its aspects is not limited to the particular type of connection between the receptacle and the syringe tube 34, the preferred form of connection which is illustrated will be found quite advantageous, as the valve 29 is a self-closing valve, and no screw stopper or other closing device is required which may become lost in the use of the article. It is only necessary to insert the nipple 33 in position within the valve to establish the proper connection of the tube 34 so as to adapt the device for use as a syringe, and likewise it is only necessary to withdraw this nipple and the valve 29 will be self-sealing against leakage, and the device will be ready for use as a hot water bag or ice bag.

Adjacent its lower end the wall of the bag It may be provided with a thickened portion 35 through which an opening 36 is provided, so that the bag may be suspended from a nail, hook or the like, the opening 36 through the side wall of the bag communicating with an opening or slot 31 formed in the bottom or lower edge of the bag, also within the thickened portion 35. In case a hook is used, the free end thereof may be accommodated in the slot 31. This provision obviates the necessity of any projecting tab or the likev which would not conform to the lines of the bag itself.

Our improved bag as herein shown has a neat, attractive appearance inasmuch as when closed it presents the shape of a shallow rectangular body with rounded corners and rounded edges. The bag is streamlined as distinguished from one having unsightly projections, and yet it has satisfactory leak-proof closure means, syringe-tubeconnecting means, and suspension provisions.

While we have shown and described a preferred embodiment of our invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and wihin the scope of the appended claims.
