May 3, 1938. M; H. BROWN WATER BAG Filed oct. e, 1957 Patented May 3, 1938 UNITED STATES WATER BAG Mae H. Brown, Polk, Mo.
Application October 6,
The present invention relates to water bags and more particularly to improvements in the construction and uses of a liquid container of f this type.
In the use of water bags, it is essential for the cooling or heating liquid to be uniformly applied to the part of the body being treated. If the liquid is allowed to escape from the affected part, its efiiciency will be seriously impaired. Accordingly, an important feature of the present invention is to provide a liquid receptacle such asv a hot or cold water bag, with means in the form of separate compartments for receiving and retainingor localizing the liquid therein irrespective of the different shapes the bag may assume or the varying pressures to which it may be subjected when in use.
A further object consists in providing the bag with an inlet or filling passage in the form of a tubular member for conducting the liquid to `the compartments, and associating with the tubular member a removable closure for cutting off communication of the compartments with one another and for effectively providing a leakproof closure when the parts are applied.
A further object consists in providing the water bag with interchangeable closure means and a removable syringe connection whereby the bag may be readily used as a syringe or the like.
Other objects and advantages of the invention .will become apparent from the following -description when taken in conjunction with the accompanying claims and drawing.
Referring to the drawing in which are disclosed several preferred embodiments the invention may assume:

Referring to the drawing in which like numerals indicate like parts in the several views, Ill designates the body of a water bag which may 1937, Serial No. 167,622
(Cl. 12S-258) be formed of soft, flexible, Water-proof material such as rubber or the like, and which interiorly is provided with spaced partitions II which constitute separate compartments or chambers I 2 for receiving the hot or cold liquid, and which are arranged to retain the same within a prescribed or restricted area of the bag. The partitions II may be integrally connected to the top I3 and the bottom I4 of the bag in order to constitute a one piece structure and may be made of the same material as the bag. The bag Ill may be of any desired shape and size and has extending upwardly from the bottom I4 a tubular portion or member I5 of hard rubber, vulcanized or otherwise secured to the soft rubber of the bag, s'o as to provide a filling and discharging passage I6. 'I'he member I5 has a reduced lower wall I1 provided with spaced circumferentially disposed openings I8 communicating with adjacent compartments I2 for conducting the liquid from the passage I6 to the compartments. In other words, the passage I6 constitutes a common means for filling the compartments as well as for receiving the liquid from the compartments. 'I'he tubular portion I5 is preferably positioned adjacent one end and medially of the width of the bag. The inner ends of the partitions II are preferably of hard rubber and are secured to the outer side of the tubular portion I5 between the openings I 8, in order that the compartments I2 may extend outwardly from the tubular portion I5 toward the sides of the bag. Thus, the entire area of the bag is divided into spaced elongated compartments in which the liquid may be conned.
Above the openings I8, the tubular portion I5 has a laterally disposed shoulder or offset portion I9 and an interiorly threaded enlarged flange or neck 20 which constitutes a filling mouth for introducing the liquid into the compartments I2 through the passage I6 and the spaced openings I8. The threaded neck 26 interchangeably receives either a long threaded closure or cap 2| (Figure 3) or a relatively short threaded closure 22 (Figure 4), depending upon the use to which the bag is to be applied. The inner end of the reduced portion I'Iy is preferably threaded as at 23 for coacting with the threads on the neck to rigidly secure closure 2| to the bag.
The closure 2l has an enlarged smooth external portion 24 (Figure 3) and a reduced depending skirt 25externally threaded as at 26, which are connected by an offset portion 2l. When the closure is applied to Vthefbag, the smooth portion 24 will be spaced from the threads of the neck 2|] and the threadsv 26 of the skirt 25 will engage the threads 23, thus providing means to rmly but releasably secure the closure to the bag. At the same time, the skirt 25 will extend below the openings I8 to cut off communication between the compartments I2 and the central passage or opening I6 so that the liquid in the compartments will be retained therein and prevented from escaping from one compartment to another.
In order to provide a leak-proof connection when either the closure 2| or the closure 22. is
applied to the bag. a gasket 21 may be positioned on the shoulder I9 to engage a portion of the` closure, and thus preclude the liquid from escaping through the tubular member I5.' The side of the bag adjacent the member I has an internally threaded discharge port 28 (Figure 3) which registers with one of the openings I8 and is normally closed by the threaded plug 29.
' When it is desired to use the bag I0 as a hot or cold water bottle, the closure is removed therefrom and liquid at the desired temperature is initially introduced into the opening I6 of the tubular member I5 from where it is distributed into the compartments I2 through the openings I8. The closure 2I is then applied (Figure 3) so that the lower threaded portion thereof engages the complementary threaded portion on the tubular member, and as the shoulder 21 is brought into engagement with the gasket 21, the latter is compressed and thus provides a tight seal for preventing the escape of the liquid through` the tubular member'. The shoulder 21 also limits the inward movement of the closure. When the cap is properly applied, the skirt 25 cuts off communication between the compartments I2 and the opening I6 in the tubular'mcmber and also closes communication of the compartments with one another. Thus, the liquid in each-compartment is effectively retained therein and prevented from escaping from one compartment to another. In, the event the bag is desired to be used as a syringe when the compartments are lled with water, it is merely necessary to rst remove the plug 29 from the threaded opening 28 and substitute therefor the threaded nipple 30 of the syringe tube (Figure 5). The closure 2I is now replaced by the cap 22 so that the liquid in the compartments I2 mayV escape into the central passage I3 through the openings I8 and discharge through the nipple 30 to the syringe. When the closure 22 is applied,` the lower end thereof abutsV the gasket 21 to prevent the escape of liquid through the tubular member. The end of the bag I0 opposite the tubular member I5V may be provided with an outwardly extendingtab 32 having an opening 33 for constituting suspending means to support the bag on a nail or the like when the bag is used as a syringe.
In the modied form ofthe invention illustrated in Figure, the tubular portion or mouth 34 of the bag is constructed in'substantially the same manner as the member I5 previously described and has its lower annular wall 35 provided with spaced circumferentially disposed openings 35, each of which communicates with an aligned compartment 31 similar in construction to the compartments I2. The Ywall 35 is connected to an enlarged interiorly threaded neck Y38 Yby an ciiset portion or shoulder 39, but is not interiorly ireaded as in the form previously described.
Associated with the tubular member is a removable closure 40 which has an enlarged threaded portion 4I arranged to engage the threads of the neck 38. The closure 49 is also provided with a reduced depending skirt 42, spaced from the adjacent wall 35 of the tubular member. The skirt 42 is arranged to receive a tapered annular band or gasket 43 of substantially the same length as the length of the outer portion of the skirt, so that upon the cap being threaded to the tubular portion 34, the band 43 will be moved downwardly intowedging engagementbetween the wall 35 and the` skirt 42 to close the openings 36, and
thus provide a tight seal for preventing the escape of liquid from the compartments 31 into vandthrough the tubular member. lopenings in the tubular member such as 44 has One of the its wall threaded to receive either the plug 29 or the syringe nipple 30 so that the bag may be interchangeably ,used as a hot or cold water bag or as a syringe.
The tubular member in each form of the invention shown andthe closures associated therewith, are preferably made of hard rubber composition so as permanently to maintain their preformed shapes, but if desired, these parts may be-formed of suitable metal.
Thus, it will be seen that the present invention provides a water bag having separate compartments for receiving the heating or cooling liquid, and in which means are provided in the form of interchangeable, closures for either closing communication between the various compartments or permitting the discharge of the liquid therefrom. When the bag is used as a hot water bottle, the closure applied thereto will cut off communication of the compartments from one another so that the bag may be applied to vthe affected portion of the body without danger of the liquid escaping to remote portions of the bag. Moreoventhe liquid in each compartment will be effectively retained therein so as to localize its heating or cooling area irrespective of the position or shape the bag may assume.
Further, when it is desired to convert the bag into a syringe, it is merely necessaryV to substitute for the closure plug 29, the nipple 30 and to remove the cap 2| and apply the cap 22 so that the liquid in the several compartments may discharge into the central passage of the tubular member and through the nipple 30 to the syringe.
As shown in Figure 5, the discharge opening in the nipple 30 is of such a size as to permit the ordinary flush flow of the liquid from the bag I9 into the syringe tube. In certain instances, it isV desirable that the water discharge slowly and at a predetermined rate through the syringe tube. Accordingly, there may be provided a threaded nipple 45 as shown in Figure 5a, which maybe readily substituted for the nipple 3l) to connect the syringe'with the bag I0. As shown, the nipple 45 has a restricted opening or discharge passage 46 of such a size that the water in the bag iiows through the nipple 45 at the rate of about one quart anV hour. Manifestly, the size of the opening 46 may be varied as conditions warrant. yMoreover, instead of providing a separate nipple to control the flush ow to the syringe, other means such as a Washer or the like may be associated with the nipple for this purpose.
It is vto be understood that the forms of the invention shown and described are merely illustrative of preferred embodiments and that such changes may be made as fall within the purview of one skilled in the art without departing from the spirit of the invention and the scope of the appended claims.
