Abstract

Disclosed is a fluid container having a flexible bag containing a diluent and having a closing film at its upper end, a capsule connected to the flexible bag, a drug container held in the capsule and a communicating member for communicating the flexible bag with the drug container. The communicating member has a double-edged hollow needle having a hub in the midway thereof, and a controlling mechanism for controlling the order of communication in such a manner that the plug of the drug container is stuck with one edge of the needle and thereafter the closing film of the flexible bag is stuck with the other end of the needle. The mixing procedure is sure and simple, and can be carried out in a short period of time.

Claims

1. A fluid container, comprising:

a flexible bag containing a diluent therein and having a fluid passage with a closing film at an upper end thereof;

a capsule connected to the flexible bag;

a drug container held in the capsule, an opening of the drug container being sealed hermetically with a stickable plug;

communication means communicating the flexible bag with the drug container wherein the communicating means comprises an elongated hollow needle having two pointed ends and having a hub midway thereof, and controlling means for controlling the order of communication in such a manner that the plug of the drug container is stuck with one end of the needle and thereafter the closing film of the flexible bag is stuck with the other end of the needle.

2. The fluid container of claim 1, wherein the drug container comprises a vial.

3. The fluid container of claim 2, wherein the controlling means is attached to the hub of the needle and engages with a stopper formed on an inner wall of the capsule, the controlling means being so designed as to come off from the stopper and enable the needle to move downwardly when the vial is moved downwardly to such a position that a plug of the vial is stuck with the needle.

4. The fluid container in claim 2, wherein the flexible bag has a fluid outlet at a lowest end portion thereof.

5. The fluid container of claim 3, wherein an elastic body is placed on the surface of the closing film of the flexible bag on the side of the capsule.

6. The fluid container of claim 3, wherein the needle is slidably and liquidtightly sealed with a rubber-like elastic sealing means in the fluid passage.

7. The fluid container of claim 3, wherein a cap for lowering the vial is airtightly put on the capsule.

8. The fluid container of claim 7, wherein the cap has a hanger member at its top surface.

9. The fluid container of claim 7, wherein the cap is so designed as to enable downward movement of the vial when the cap is pushed down.

10. The fluid container of claim 7, wherein the cap is so designed as to enable downward movement of the vial when the cap is rotated.

11. The fluid container of claim 3, wherein the capsule has an opening at its upper end, a flexible member is attached to the opening, and the flexible member is substantially deformable in order to enable the vial to go down by pushing down the flexible member with a finger.

12. The fluid container of claim 11, wherein the flexible member has a central flat portion and plural wrinkles around the flat portion.

13. The fluid container of claim 1, wherein the needle has one liquid passage.

14. The fluid container of claim 1, wherein the needle has two liquid passages.
