My invention relates to any hygienic container.

Among the objects of my invention are to provide a container so constructed that liquid may be withdrawn therefrom with the danger of contamination minimized, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

Referring to the drawings Figs. 1 to 4 are front sectional views of my invention. Fig. 1 shows a removable tube; Fig. 2 shows a tube permanently xed to the neck of the container by welding or the like; Fig. 3 shows the tube xed to the container by a ground joint beveled; and Fig. 4 shows the tube held by a cork fitted to the neck. Figs. 5, 6, 7 and 8 are also front sectional views of my invention. Fig. 5 shows an enlarged portion of the tube at the upper end; Fig. 6 shows the enlarged portion at the upper end of the tube as extending beyond the container itself; Fig. 7 shows an enlarged portion of the tube at the lower end; Fig. 8 illustrates the double tube. Figs. 9, 10 and 11 refer more particularly to the ampuls and are front sectional views thereof. Fig. 9 shows the tube without an enlarged portion; Fig. 10 shows the tube with an enlarged lower portion; and Fig. 11 shows the tube with `an enlarged lower closed portion.

While I have shown herein preferred embodiments of my invention yet I wish it understood that the same are susceptible of modification and change without departing from the spirit of my invention.

My invention comprises a container I0 having a mouth II sealed by a stopper I2. Said stopper I2 has an extension I3 extending down into a tube I 4, said tube connected to the neck I 5 of the container I0 and extending down into the container but ending short of the bottom of said container. The container I E3 is substantially filled with liquid but leaving a small portion of the container adjacent its neck I5 unfilled for an air space I6. The tube I4 has an air inlet II adjacent the shoulders I8 of the container I0 and a liquid inlet I 9 adjacent its lower portion 20 and on the side opposite the air inlet I'I. A stop member 2! is placed within the tube I4 adjacent the liquid inlet IS.

In use my device is applicable particularly to instances where small containers filled with medicated solutions are carried by physicians for quick use. The physician removes the stopper I2 and inserts his needle into the tube and with- Air from the air space IE is pressed down by new air coming in through the opening II caused by removal of the stopper I2 and passes through air inlet I'I to relieve the vacuum and forces liquid into liquid inlet I9-and thus up into tube I4. 5 The needle can only touch that portion of the liquid which is within tube I4. In the liquid in the container there may be foreign bodies. If these foreign bodies are heavy they will settle to the bottom of the container below liquid inlet 10 I 9 and are thus impounded in the sediment chamber 23 where they cannot be withdrawn. Likewise none of the surface of the liquid which may lioat foreign bodies is withdrawn. Therefore the danger of contamination is minimized by my l5 structure. Y

In Fig. 1 I provide for a removable tube I 4, by placing screw threads 24 on the tube which meet screw threads 25 on the neck I5 of the container. This permits the removal of the tube 20 I4 so that the container I0 can be more easily filled or cleared.

In Fig. v'2 the tube I4 is permanently xed to the neck of the container by welding or the like. In Fig. 3 the tube I4 has an enlarged 25 top portion 26 which is fixed to the neck of the container by a ground joint beveled. In Fig.

4 a cork 21 is tightly tted to the neck of the container and is hollowed out to receive and hold the tube I 4. 30

Another embodiment of my invention shown in Fig. 5 discloses the container I0 filled with liquid so as to leave no air space I6 within the container itself.

The tube Ill is enlarged adjacent its top portion 35 to form an expansion chamber 28. After the container is lled with liquid the tube I5 is inserted and the enlarged portion 28 is fixed lto the neck I5 by an annealed or mechanical joint.

Liquid also fills a portion of the enlarged por- 40 tion 28 to a predetermined level leaving an air or vacuum space 29. Because of changes in temperature liquid may expand. It is, therefore, desirable to leave a space unfilled with liquid so that if the liquid expands it may occupy this 45 space. Otherwise, expansion would cause breakage of the container. With my enlarged portion 28 the container itself may be completely lled without the necessity of space if corresponding space 29 is allowed in the enlarged portion. The 50 liquid may if heated expand into space 29. This allows a complete lling of the container and assures full measure, particularly when the enlarged portion extends beyond the container as in Fig. 6 and as later described herein. Another 55 function of enlarged portion 28 is to increase the amount of liquid that can be withdrawn from the tube at one operation of a needle.

As in Fig. 1 where the tube is removably attached to the neck by screw threads my tube having enlarged portion 28 may be removably attached to the neck by placing screw threads on both the enlarged portion 28 and the neck I5. These parts may also be removably joined by means of a ground joint. Likewise as in Fig. 4 a cork lor the like may t within the neck I5 and have a hollowed out portion to receive and hold enlarged portion 28.

While I prefer to have the enlarged portion 28 within the container ID yet I may iind it desirable (see Fig. 6) to have the enlarged portion 28 eX- tend beyond the container so that the closure or cap instead of tting over the mouth of the container will be removably xed to the top of the enlarged portion 28 by screw threads or other suitable means.

As variations I may provide that the liquid inlet I9 instead of being placed on the side of the tube I4 be located at the bottom of tube I4. I may also provide the tube It adjacent its bottom portion with an enlarged sediment chamber 30, as shown in Fig. 7.

I may also provide that the tube I4 eliminate the air inlet I'I as hereinbefore disclosed. Instead I provide the tube I4 having a second passage 3l leading from the neck of the container and ending within the container adjacent the shoulder I8 of the container lil as in Fig. 8.

My 'invention is applicable to the type of container which is sealed by a removable cap and it is also adaptable to ampuls or other one piece sealed glass containers, as shown in Figs. 9, 10 and 11.

My container besides being Aa device from which liquid may be hygienically withdrawn may also be used as a shaker. Since it is so difficult to add liquid to my container my device may be used where it is desired to insure that the original contents have not been diluted, or changed.

Wherever I employ an ampul I provide a removable trap` 32 which in one form will float on the liquid adjacent the top of the container or expansion chamber. My trap has a receiving portion 33, a handle 34 and in one form an anchor 35. Another embodiment eliminates the anchor and instead of floating, my trap 32 is held by arms 36 to turns 3l in the ampul. When the ampul is broken any glass which may fall into the container will drop into the receiving portion 'of my trap. I merely remove the trap by using the handle 34. (See Figs. 9, l0 and l1.)

As shown in Fig. 11 I may provide for an expansion chamber 38 at the bottom end of the tube I4. This will allow the complete lling of the container with liquid since any expansion will be within the expansion chamber.

As particularly shown in Fig. 7 I employ a cork sleeve 21 tightly fitted to the neck of the container III and hollowed out to receive tube I4. When the air inlet II is flush with the cork 21 no air can enter the container.
