Abstract

A container for storing a biological sample for molecular diagnostic testing and/or histological testing is provided. The container includes a first chamber for receiving a sample holder therein, a second chamber, and a closure for enclosing the container. A breakable membrane, such as a piercable foil, extends within the container and separates the two chambers. When the breakable membrane is broken, fluid can pass between the first and second chambers. The membrane may be broken through an activator on the closure, such as a depressible member or a rotatable carrier, causing the sample holder to break through the membrane.

First claim

What is claimed is:

1. A container for storing a biological sample, comprising:
a housing extending between a first open end and a second end, defining a container interior;
a removable closure for enclosing the first open end; and
at least one breakable membrane separating the container interior into at least a first chamber and a second chamber in fluid isolation from the first chamber, wherein the first chamber is open to the first open end of the housing and is adapted to receive a sample holder therein, the breakable membrane breakable to establish fluid communication between the first chamber and the second chamber,
wherein the sample holder comprises a closable housing defining an internal cavity for holding a biological sample and a closable member for enclosing the internal cavity, and
wherein the container is configured such that the removable closure is capable of enclosing the first open end when the closable member encloses the internal cavity.

2. The container of claim 1 , wherein the sample holder is detachably connected to the closure for insertion into the first chamber of the container interior.

3. The container of claim 1 , wherein the closure is threadably matable with the housing.

4. The container of claim 1 , wherein the sample holder is rotatable with respect to the closure to maintain the sample holder in a substantially stationary position within the first chamber during engagement of the closure with the housing.

5. The container of claim 1 , further comprising a platform attached to the closure and adapted for receiving the sample holder for insertion into the first chamber of the container interior.

6. The container of claim 5 , wherein the closure is threadably matable with the housing and wherein the platform is rotatable with respect to the closure to maintain the sample holder in a stationary position within the first chamber during engagement of the closure with the housing.

7. The container of claim 1 , wherein the closable housing comprises a plurality of fluid openings adapted for allowing fluid contained within at least one of the first chamber and the second chamber to pass into the internal cavity.

8. The container of claim 1 , wherein the sample holder is a histology cassette.

9. The container of claim 1 , further comprising a first fluid disposed within the first chamber and a second fluid disposed within the second chamber, wherein the first fluid is different than the second fluid.

10. The container of claim 1 , wherein the at least one breakable membrane is a pierceable foil.

11. The container of claim 1 , wherein the housing further comprises a longitudinal axis, and the breakable membrane extends across at least a portion of the container interior transverse to the longitudinal axis, thereby establishing the first and second chambers.

12. The container of claim 1 , wherein the container further comprises a movable structure extending from the container interior to an exterior of the container such that movement of the movable structure causes the breakable membrane to break, thereby establishing fluid communication between the first and second chambers.

13. The container of claim 12 , wherein the moveable structure comprises a depressible element and wherein the sample holder is connected to the depressible element such that depressing the depressible element causes at least a portion of the sample holder to break the breakable membrane.

14. The container of claim 13 , wherein the depressible element comprises a flexible elastomeric button.

15. The container of claim 13 , further comprising a removable cover disposed over the depressible element for preventing movement of the depressible element.

16. The container of claim 12 , wherein the moveable structure comprises a rotatable carrier and wherein the sample holder is connected to the rotatable carrier such that rotation of the rotatable carrier causes at least a portion of the sample holder to break the breakable membrane.

17. A container for storing a biological sample, comprising:
a housing having a first open end, a second end, and defining a container interior, the housing having a longitudinal axis;
a breakable membrane extending across the container interior transverse to the longitudinal axis, thereby separating the container interior into at least a first chamber and a second chamber, the breakable membrane breakable to establish fluid communication between the first chamber and the second chamber, wherein the first chamber is aligned with the first open end of the housing and is adapted to receive a sample holder therein; and
a removable closure for enclosing the first open end, the removable closure comprising a depressible element and having the sample holder connected therewith, wherein depressing the depressible element causes at least a portion of the sample holder to break the breakable membrane,
wherein the sample holder comprises a closable housing defining an internal cavity for holding a biological sample and a closable member for enclosing the internal cavity, and
wherein the container is configured such that the removable closure is capable of enclosing the first open end when the closable member encloses the internal cavity.
