CONTAINER AND METHOD FOR RECONSTITUTION OF SUBSTANCES
A method for reconstitution of substances includes a liquid container having a pre-determined volume of diluent and a powder container having a corresponding pre-determined amount of powder to be reconstituted. The method allows an individual to safely reconstitute the powder into a liquid solution having the desired concentration without measuring or potential spillage. The powder container includes a female threaded connection designed for liquid-tight attachment to the liquid container and further includes a breakable membrane seal which, when broken by the distal end of the liquid container, creates an orifice for the diluent to enter the powder container to reconstitute the powder and thereafter be displaced into the liquid container for use. Before the membrane seal is broken, the pre-determined amount of powder partially occupies the powder container chamber.

3 . A disposable container for reconstituting a powder into a liquid, the container comprising:
a chamber having partially disposed within a pre-determined weight of a powder for reconstitution;
a breakable membrane seal which when broken by tip of a separate liquid container, creates an orifice for diluent entry from a separate liquid container into the chamber and reconstituted liquid from the chamber into the separate liquid container;
a cylindrical wall located on the side of the breakable membrane seal opposite the chamber, the cylindrical wall having female threads and the interior space surrounding the cylindrical wall defining a cavity;
an outer cylindrical wall, concentric with said cylindrical wall and further having at least one radial support integrally connected to both walls; and,
a removable adhesive seal covering the cavity.
4 . (canceled)
5 . The disposable container of claim 3 further comprising a protective adhesive film covering the distal circumference of the cylindrical wall.
6 . (canceled)
7 . The disposable container of claim 3 where said container is made of a transparent plastic material.
8 . The disposable container of claim 3 where said pre-determined weight of powder occupies up to about 25% of the chamber.
9 . A container comprising:
a transparent thermoplastic body having a chamber and within said chamber is a pre-determined weight of a powder for reconstitution that occupies up to about 25% of the chamber;
a portion of the thermoplastic body having a reduced wall thickness relative to the other portions of the body that defines a breakable membrane seal which when broken by tip of a separate liquid container, creates an orifice for diluent entry from a separate liquid container into the chamber and reconstituted liquid from the chamber into the separate liquid container;
a cylindrical wall located on the side of the breakable membrane seal opposite the chamber, the cylindrical wall having female threads and the interior space surrounding the cylindrical wall defining a cavity;
an outer cylindrical wall, concentric with said cylindrical wall and further having at least one radial support integrally connected to both walls; and,
a removable adhesive seal covering the cavity.
10 . The container of claim 9 where the orifice is sufficiently limited in diameter to prevent discharge of the pre-determined amount of powder while in powder form.
