wherein like numerals have been employed to designate similar, parts. throughout the various figures, it will be seen thatone embodiment of the. present. invention. consists of a receptacle designated generally, by the numeral l0, This receptacle 1.0 includes an outer container or jar l-2 which maybe madeof any suitable material, such as glass, plastic or the like. The. container I2 is open at one end and is threaded at I14 to accommodate. a complementary annular clamping member or ring [6. The upper portion of the wall. of; the container I2. is provided with a nipple [8 for accommodating a rubber hose or stopper, and thelower portion of the wall of thecontainer is provided with a similar nipple 2B. The. use for these. nipples l8v and, 2.0, will be more apparent a the description progresses.

Positioned. within the container I2 is a second container designated generally by the numeral 22. This container 221 consists of a fluid retaining body. portion. or bag 24, th lower end of which. is sealed as at. 26, and the upper end of which. is, secured to theinner surface of a rubber like cap 28. In the disclosed embodiment the cap 28 is of conical shape, the base of which presents. an. annular flange 30. extending laterally of the periphery of the bag or sack 24,, and; the crown 321 of which. presents a section for accommodating a. sharp instrument such as ahypodermic needle 34. The crown seotion 32 must be thick enough, and the, rubber like material; must be such as. torender the-same self-sealing. after the needle. 34 has been. withdrawn. The flange 3 0, is designed to be clamped against the upper margin of thecontainer-or jar Why the threaded clamping ring [6, as; clearly shown in Fig. 3. When clamped in this position the bag 24 presents a liner for the inner periphery of the eontainer l2, and in order to maintain spaced.rela tion between the inner. peripheryof the container 12 and the outer periphery of the bag 24, longitudinally. extending ribs, 36- are circumferentially spaced along the inner surface of the container l2 This is clearly illustrated in Fig. 6. Inv Fig. 6 thecon-tainer orjarl2 isshown as being made of. glassor; porcelain, whereasin the modified disclosurein Fig, 7 a, similar container In is shown whiQhmay, be made of moldable plastic material. In: such instances ribs 36a. may be molded or pnes edinward w With the\ inner saclgor bag 24-. secured. or clamped in position by the ring It as shown in Figs.- 1 audit, the needle: maybe inserted within the self sealing capiz as shown in Fig. 3, As shown in Fig. 1, this needle. 34, may be connected to a blood donor in theusual manner as by means of a flexible tube-38=, and: a second. needle (not shown). Obviously, the bag 24 must be internally aseptic'and in instances where desirable a quantity of suitable anti-coagulant may be sealed within the bag. Such an anti-coagulant may be placed in the bag at the time of its manufacture just prior to sealing the lower extremity 26 thereof. When the required amount of blood has been withdrawn from the patient, the needle 34 may be removed, and due to the self-sealing characteristics of the crown 32 the blood is completely sealed within the bag. For transfusion purposes it is only necessary to invert the receptacle It, as shown in Fig. 2, to thereby permit withdrawal of the fluid from the sack 24. A suitable bail 40 connected with the container [2 may be used to support the receptacle in its inverted position. Nipples l8 and 20 may be employed in instances where either vacuum conditions or pressure conditions within the container [2 are necessary to speed the flow of fluid into or away from the fluid retaining bag 24. In instances where gravity feed is sufficient, these nipples may remain open as shown in the drawing. The nipples lend themselves for connection to flexible tubing or rubber stops depending upon the needs incident to their use. After the fluid, such as blood, has been completely withdrawn from the sack 24, this sack and the cap 28 secured thereto may be disposed of. In other words, the invention contemplates the provision of a fluid receptacle, the outer container portion of which may be reusable, but the inner portion disposed of after it has served its purpose.

Attention is also directed to the fact that the disposable container device 22 is preferably collapsible, as shown in Fig. 5. Heretofore, particularly in connection with blood transfusions, jars, such as glass jars, have been employed to receive the blood. After the blood has been withdrawn these jars must be thoroughly cleaned and sterilized. It has not been uncommon to experience considerable difliculty in properly cleansing these jars. Furthermore, jars of this type represent considerable bulk, and hence the shipment thereof represents a considerable item of expense, this being particularly true because of the breakable nature of such containers. Due

to the collapsible feature of the fluid accom- I modating inner container described above, such containers may be shipped in compact form, cupying a minimum amount of space and completely avoiding any hazard of breakage. Furthermore, a relatively large inventory of these containers may be kept without requiring a large space for such storage.

In the manufacture of the inner container or liner, it is proposed to employ a suitable thermoplastic material for the bag portion. The closed end of the bag may be suitably cemented or adhered to the inner surface of the rubber like cap, and a suitable anti-coagulant may be introduced within the flexible bag. Thereafter the open end of the bag may be suitably sealed at 26, after the air has been completely withdrawn from the bag. This sealed end of the bag may be rolled into a compact mass, leaving the end portion thereof and associated self-sealing rubber cap substantially maintained against collapsing as shown in Fig. 5. It will also be understood that the inner surface of the bag must be completely aseptic. This may be accomplished by employing aseptic material for the bag or aseptically treating the inner surface of the bag.

From the foregoing it will be apparent that the present invention facilitates the storage of fluids which have a tendency to deteriorate quickly when subjected to the atmosphere. This is particularly true in connection with the handling of blood. Furthermore, the invention not only assures storage of fluid free from contact with the atmosphere, but also introduces considerable economy in the handling of such fluids. That is to say, it makes possible the use of a relatively inexpensive and easily disposable, internally aseptic fluid container, as distinguished from the use of conventional glass jars and the like which are easily breakable and difiicult to sterilize. Obviously, the structure of the outer container may be varied to meet the needs for which it is to be used, and likewise the structural details of the internally aseptic container may also be varied depending upon the manner in which it is to be mounted for use. Thus, where the fluid flow to or from the bag 24 is only under gravity feed, it is not necessary to seal the outer container. In other words, changes and modifications are contemplated which come within the scope of the appended claims.

The invention is hereby claimed as follows:

1. A fluid receptacle including an open ended outer container, a second internally aspectic and hermetically sealed inner container forming a removable liner for the outer container and adapted for storing fluid and including a rubber like self-sealing section adapted to be punctured by a sharp instrument such as a needle, for charging the inner container with fluid and discharging fluid therefrom and means disposed peripherally on the inner container and secured thereto and disposed between said inner and outer containers for supporting said inner container in operative position within said outer container with the rubber-like section disposed in an eX- posed readily accessible position.
