ABSTRACT:
A closure and device for use with a closure, the closure including a first member having a beveled edge, a second member having an undercut edge, and optionally a base member to which the second member is fixed. The first member is adapted to be received with the beveled edge retained by the undercut edge. A test device may include such a closure and may also include a hinge between the first and second members. Test elements, such as a chromatographic medium and absorbent pads, may be disposed on the first member and/or the base member and may be brought into opposition by closing the first member with the closure.
