Apparatus for storing and selectively mixing at least two distinct substances in a common package has a container (10) for creating a substance holding chamber (16) in which is disposed a barrier (18) arranged for separating the chamber into at least two compartments (20, 22) each holding a predetermined quantity of a substance different from a substance being held in the other compartment. Provision is made for exerting an external force on the barrier so as to open same and cause communication between the compartments. Subsequent mixing of the substances contained in the compartments is achieved either by continued movement of the barrier or by a separate mixing device.

1. Apparatus for storing and selectively mixing at least two distinct substances, comprising in combination: A. container means for creating a substance holding chamber; B. barrier means arranged within the chamber of the container means and normally attached thereto for separating the chamber into at least two compartments, each of the compartments holding a quantity of a substance different from a substance being held in each of the other of the compartments; and C. combining means connected to the barrier means for selectively applying a twisting motion to the barrier means and separating the barrier means completely from the container means, permitting the selective communication with one another by an external force of the compartments formed by the barrier means within the chamber of the container means, and allowing a substance within each of the compartments to intermix with a substance from each of the other compartments formed by the barrier means. 2. Apparatus as defined in claim 1, wherein the combining means includes actuator means operable by an external force for permitting selective opening of the barrier means with respect to the container means. 3. Apparatus as defined in claim 1, wherein the combining means further includes tear means associated with the barrier means for facilitating opening of the barrier means with respect to the container means. 4. Apparatus as defined in claim 3, wherein the combining means includes external force operable actuator means for permitting selective opening of the barrier means with respect to the container means. 5. Apparatus as defined in claim 3, wherein the actuator means includes the barrier means comprising an element provided with a socket opening externally of the container means and arranged for receiving a tool which facilitates twisting of the barrier means relative to the container means and causing the desired opening of the barrier means. 6. Apparatus as defined in claim 1, wherein the container means includes mixing means actuable by an external force for blending each substance with any other substance within the container means. 7. Apparatus as defined in claim 6, wherein the barrier means forms the mixing means. 8. Apparatus as defined in claim 6, wherein the mixing means is separate from the barrier means. 9. Apparatus as defined in claim 8, wherein the combining means includes a stem attached to both the mixing means and the barrier means, the stem being arranged for selectively receiving an external force and initially opening the barrier means, and subsequently actuating the mixing means. 10. Apparatus as defined in claim 9, wherein the stem has a longitudinal extent, and is provided with a socket opening externally of the container means and arranged for receiving a tool which facilitates rotation of the stem about the longitudinal extent thereof. 11. Apparatus as defined in claim 1, wherein the barrier means includes a vessel disposed within the chamber of the container means, the vessel arranged forming one of the compartments of the chamber. 12. Apparatus as defined in claim 11, wherein the combining means includes tear means associated with the vessel for facilitating opening of the vessel as desired. 13. Apparatus as defined in claim 12, wherein a point on the vessel is affixed to the container means, the tear means being provided on the vessel and arranged for opening the vessel when the vessel is twisted about the point of attachment of the vessel to the container means. 14. Apparatus as defined in claim 13, wherein the vessel has the generally cylindrical configuration with a pair of spaced ends each having a circumference, and the tear means includes weakened portions around the circumference of each of the spaced ends of the vessel, and a further weakened portion extending between the weakened portions disposed at the spaced ends. 15. Apparatus as defined in claim 14, wherein the vessel is provided with a socket opening externally of the container means and arranged for receiving a tool which facilitates twisting of the vessel above the point of affixment thereof to the container means. 16. Apparatus as defined in claim 1, wherein the container means is provided with a side wall having formed thereon and arranged opening inwardly of the chamber of the container means a pair of opposed grooves exposed for retainingly receiving a specimen to be embedded in a mixture held in the chamber of the container means.
