1. A fluid container comprising:
- a drug container having a barrel and a narrow mouth sealed by a rubber stopper, and including first and second engaging means arranged around said barrel;
a deformable solvent container of a synthetic resin having at least one mouth sealed by a sealing means;
a cylindrical guide capsule having an open end at one end and at the other a connecting portion coupled to the mouth of said solvent container, said guide capsule being provided at an inner wall thereof with an engaging means for engagement with the second engaging means of said drug container;
a double-pointed hollow needle having a sharp piercing edge at each end and being slidably held in said guide capsule and arranged between the mouth of said drug container and that of the solvent container;
a cylindrical cap rotatably mounted on said guide capsule to seal an open end thereof as well as to hold the drug container therein, said cap being provided at an inner wall thereof with an engaging means for engagement with the first engaging means of said drug container, wherein one of said first engaging means of said drug container and the engaging means of said cap includes at least one spiral groove and projection for engaging said spiral groove, and wherein one of said second engaging means of said drug container and the engaging means of said guide capsule includes at least one vertical guide groove and projection for engaging said vertical guide groove, whereby said drug container is forced to move linearly without causing rotary motion thereof toward said solvent container when said cap is rotated, thereby allowing said double-pointed hollow needle to pierce said rubber stopper of the drug container and said sealing means of the solvent container to make a fluid communication between said drug container and solvent container through said needle.

Abstract
A fluid container comprises a drug container, a deformable solvent container, a double-pointed hollow needle having a sharp piercing edge at each end and being arranged between the drug container and the solvent container, a guide capsule with a cap rotatably mounted thereon, and a means for converting rotary motion of the cap to a linear motion of the drug container to push the drug container toward the solvent container in cooperation with the cap and the guide capsule so that a fluid communication is made between two containers through the needle.

17. A fluid container comprising:
-
a drug container having a mouth sealed by a rubber stopper; a deformable solvent container of a synthetic resin having at least one mouth sealed by a sealing means; a double-pointed hollow needle having a sharp piercing edge at each end; a cylindrical guide capsule having an open end at one end and at the other end a connecting portion removably connected to said solvent container, whereby said double-pointed hollow needle being slidably held between the mouth of said drug container and that of said solvent container, said guide capsule being provided at an inner wall thereof with one or more vertical guide grooves for guiding said drug container; a cylindrical cap having at least one spiral groove and being rotatably attached to said guide capsule to seal the open end thereof; and a vial guide having first and second projections provided on an outer surface thereof and holding said drug container therein, said vial guide being movably held in said cap in such a manner that said first and second projections of the vial guide are respectively engaged with said spiral groove of the cap and said vertical guide grooves of the guide capsule, thereby constituting a driving means for converting a rotary motion of said cap to a linear motion of said drug container without causing rotary motion of said drug container and for allowing said double-pointed hollow needle to pierce said rubber stopper of the drug container and said sealing means of the solvent container to make a fluid communication between said drub container and solvent container through said needle. - View Dependent Claims (18, 19, 20, 21, 22)
