BOTTLE NOZZLE Filed Jan. 4, 1935 Patented May 25, 1937 IUNHTED STATES ATgE NT OFFICE 4 Claims.

My invention relates to bottle nozzles and has particular reference to a device which may be employed to permit simultaneous flow of liquid from a bottle or container and inflow of air to the container.

In extracting liquids from containers, particularly bottles and similar vessels, it is necessary to permit air to flow into the bottle to replace the liquid drawn therefrom in order that the flow of liquid from the bottle or other .vessel may be in a steady stream. This is particularly advisable when the liquid is of such nature that air must be prevented from being trapped by the outgoing liquid, such as when the liquid is to :be used in treatment of certain diseases by the injection of the same from the container direct into the human body. In the practice of introducing intravenous solutions into patients in the treatment of certain diseases, particular care must be taken not only that the outgoing liquid shall not trap and carry air into the veins of the patient and that the stream of liquid coming from the vessel or bottle shall be steady but also that the air which is employed to replace the contents of the bottle shall be filtered in order to prevent contamination of the contents of the bottle or other vessel.

Various nozzles and devices have been employed to permit steady inflow of air into such bottles or vessels, these devices comprising the attachments which must be placed upon the bottle, and by reason of their intricate construction cannot be readily cleaned and sterilized, and, further, since they attach to and project from the bottle or other vessel, are subject to breakage while the treatment is being given.

It .is, therefore, an object of my invention to provide a bottle nozzle which may lie wholly within the bottle or other vessel from which the liquid is to be extracted.

Another object of the invention is to provide a nozzle of the character set forth in the preceding paragraph in which the incoming air is cairiedthrough a tortuous path, aportion of which includes a liquid seal through which the air must be filtered.

Anotherobject of the invention is to provide a device of the character set forth herein, in which the airintroduced into the bottle is at a higher level than thepoint of egress of the-liquid from the bottle, thus permitting trapping of the air in the outgoing stream.

Another object of the-invention is to provide a b ottle nozzle of the character set forth, in which the point of introduction of the air into the bottle or vessel lies at a considerable distance from the point of egress of ,thebottle, thus further preventing contamination, or trapping, of the air in the outgoing stream.

Other objects and advantages will be apparent 5 from a studyof the following specifications, read in connection with the accompanying drawing, wherein Figure 1 is a diagrammatic view of a bottle or vessel employed for administering intravenous 10 solutions, illustrating my bottle nozzle therein connected to the instruments employed in such treatments;

Fig. 2 is a perspective view of my bottle nozzle located within the neck of a bottle, similar to 15 that shown in Fig. l, the bottle being illustrated in phantom dotted lines;

Fig. 3 is a dev opment of the exterior of my bottle nozzle, illustrating the air passage and the liquid passage therein and Fig. 4, is a sectional view of a bottle nozzle constructed in accordance with my invention, taken along line IVIV of Fig. 2. 4

Referring to ,the drawing, 1 have illustrated a bottle I, representative of a bottle, container or other vessel in which liquids may be supplied ,for intravenous treatments, such bottle being ordinarily provided with a suitable neck .2 leading to an outlet or mouth 3 which, if desired, may be provided with threads or other closure attachments, whereby a cap or other closure may be placed upon the bottle to retain the contents therein. When it is desired to remove the con tents from the bottle 1, a tube 4, leading to an injectionneedle ,5, must be attached to the bottle 3 or vessel I to communicate with the interior thereof, permitting the liquid therein to flow out through the tube and out through the needle'5.

As will be understood by those skilled in the art, it is necessary that air be introduced into 0 the bottle I to replace the liquid which'isdrawh therefrom through the tube 4, and I provide a .bottle -nozzle 6 which may be inserted into ,the .neck 2 of the bottle,,the particular form of which is preferably as shown in Fig. 2. The bottle 45 nozzle '6 comprises a cylindrical section of rubber or other compressible material which may be iniserted into the neck 2 of the bottle to seattightly in the interiorthereof and form a substantial closure for the bottle.

The nozzle 6 is provided with a liquid passage bore 1 preferably extending longitudinally of the nozzle ,6 concentrically with the exterior of the fcy'lindrical 'form thereof so that the liquidis removed from the central portion of the neck of the bottle I.

By referring particularly to Fig. 4, it will be observed that the outer end of the liquid bore 1 may be initially sealed by a cap or closure 8 which may be inserted in an enlarged opening 9 at one end of the nozzle 6, or, if desired, the closure 8 may be formed as a thin membrane of the material of which the nozzle is constructed either scored or provided with gripping elements permitting the person using the same to tear out the closure 8 when it is desired to use the nozzle 6.

In order to provide into the bottle i while the contents thereof are flowing out through the liquid passage l, I provide the exterior of the cylindrical form of the nozzle E with a long air passage groove it, one end of which communicates with the exterior of the bottle and the other end of which communicates with the interior of the bottle, the groove being formed in the exterior of the nozzle member 6 so that when the nozzle is inserted in a bottle the interior wall of the bottle will close one side of the passage Ill.-

By referring particularly to Figs. 2 and 3, it will be observed that the air passage l extends from an entrance point H as a short, substantially straight passage paralleling the longitudinal axis of the nozzle 6, this portion of the passage terminating in a sharp bend at l2 from which leads a downwardly extending portion I3 communicating with an enlargement Id of the groove to constitute a liquid trap which, upon inversion of the bottle I, will partially fill with liquid as indicated at [5, closing the point of communication i6 of the enlargement I l with the section iii of the air passage. Thus any air introduced through the entrance H will be filtered through the liquid i5 before passing to the interior of the bottle or vessel. From the enlarged portion M forming the trap, a relatively small passage ll extends downwardly to a sharp bend l B from which a relatively straight portion of the passage extends upwardly, as indicated at 19, to the air outlet All in the interior of the bottle.

By referring particularly to Figs. 2 and 3, it will be observed that when the bottle I is inverted to allow the contents thereof to pass out, the bend E2 of the passage it! will lie at a slightly lower level than the point of communication between the liquid trap Hi and the section ll of the air passage, while, similarly, the entrance l6 of the liquid trap l4 will lie at a slightly lower level than the bed l8 leading to the outlet 20. Thus with but a small amount of liquid in the trap l4 the incoming air must pass through the liquid l5 and there will be little or no tendency for the entire air passage to fill with liquid to siphon off the contents of the bottle. Again it will be noted that by reason of the formation of the air passage H] at the outer surface of the nozzle member 6, the air outlet 26 at the interior of the bottle is adjacent the interior walls of the bottle, spaced a considerable distance from the liquid outlet passage 1. It will also be noted that the inner end of the nozzle 6 is cut away for half its width in the form of a notch, or recess, 2|, the cut-out portion extending over the inner end of the liquid passage 1, thus providing the point of exit of the liquid at a lower level than the point of entrance of the air coming into the bottle or other vessel.

By reason of the respective locations of the inner ends of the air and liquid passages, it will be apparent that the air coming into the bottle for the admission of air can never be trapped in the outgoing stream therefrom and thus the chance of injecting bubbles of air into a patient is avoided.

It will also be observed that by reason of the construction of the nozzle 6, as illustrated and described herein, the nozzle may be inserted in the bottle by the original manufacturer of the contents thereof, and it will remain in the bottle until it is desired to use the contents therefrom, at which time the outer closure of the bottle may be removed, the tube I l connected to the liquid passage 7, and the bottle then inverted. This permits of the ready handling of, intravenous solutions without contamination thereof by unsterile attachments which would otherwise be required to be placed upon the bottle or vessel. Moreover, by reason of the construction of the nozzle 6 the same is readily adapted to be boiled or otherwise sterilized in any sterilizer without danger of breakage thereof, and without requiring any disassembly of separate parts, as is required in the present-known devices for this purpose.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not wish to be limited to any of the details of construction shown herein, except as defined in the appended claims.
