Abstract

A lockable cell growth chamber is disclosed wherein the lid and base of the dish are provided with at least two pairs of locking members, each comprising a notched docking member and a docking member-engaging tab.

Claims

1. A lockable cell growth chamber comprising

(a) a circular dish supported on a circular base, said dish having a bottom plate and a bottom cylindrical side wall, and

(b) a circular lid having a top plate and a top cylindrical side wall, said lid sized so as to fit over the bottom cylindrical side wall of said dish

wherein said base and said lid are provided with locking means for securing said base and lid in locking engagement, said locking means comprising at least two pairs of locking members, each of said pairs of locking members comprising (i) a docking member having a notch, and (ii) a tab sized and shaped so as to be slidably and compressionably engagable with said notch of said docking member.

2. The cell growth chamber of claim 1 wherein said docking member is integral with said bottom cylindrical side wall and said tab is integral with said lid.

3. The cell growth chamber of claim 2 wherein said docking member has a land in the vicinity of said notch that is sized and located so as to be matingly engagable with said tab.

4. The cell growth chamber of claim 3 wherein said docking member includes a ramp and said notch is substantially centered in said ramp.

5. The cell growth chamber of claim 4 wherein said docking member includes a platform that is substantially at right angles to said ramp.

6. The cell growth chamber of claim 5 wherein said top cylindrical side wall includes a stop adjacent each tab.

7. The cell growth chamber of claim 6 wherein said stop is located and shaped so as to engage one side of said docking member when said tab is within said notch.

8. The cell growth chamber of claim 1 wherein said docking member and said tab are slidably engagable with each other by rotating said lid relative to said base.

9. The Petri dish of claim 8 wherein said docking member and said tab are slidably disengagable from each other by rotating said lid relative to said base.

10. The cell growth chamber of claim 1 wherein said lid is transparent.

11. The cell growth chamber of claim 1 wherein said base has a circumferential flange.

12. The cell growth chamber of claim 1 wherein said dish contains microorganism growth medium.

13. The cell growth chamber of claim 12 packaged in sterile packaging.
