Patent ID: 7713734

Claim:
A cell culture device comprising: a base, wherein the base comprises: a planar top member and one or more side walls, each with an upper and lower edge, wherein the one or more sidewalls adjoin the planar top member at the upper edge; a well formed in the top member; a groove surrounding the well between the planar portion of the top member and the well; and one or more notches in the lower edge of the one or more side walls configured to receive a latching mechanism; a cover, comprising: a planar top member having an upper and a lower surface, and one or more side walls, each with an upper and lower edge, wherein the one or more side walls adjoin the planar top member at the upper edge; a well formed in the top member of said cover; a ridge formed on the lower surface of the planar top member and surrounding the well; and one or more latching mechanisms on the lower edge of the one or more side walls of said cover; and a ring structure sized to fit snugly in the bottom of the well of the base and of a height to contain sufficient cell culture media to enable culturing of cells in the well of the base; wherein the cover is of similar overall shape as the base and fits snugly over the base, such that when the cover is placed on the base; the well of the cover fits into the well of the base and extends into the well of the base to rest against the ring when the ring is in the well of the base; the side walls of the cover fit alongside and enclose the side walls of the base; at least one latching mechanism in the lower edge of a cover side wall is aligned with a notch in the lower edge of a base side wall; and the ridge on the lower surface of the planar top member of the cover fits into the groove in the base.
