1. A reclosable testing device, comprising:
- a base member;
a cover member;
a fixed member fixed to the base member, the fixed member having an undercut edge;
a hinge between the base member and cover member;
a testing element fixed to at least one of the base member or the cover member; and
,closure means comprising a beveled edge on the cover member, the beveled edge being supplementary to the undercut edge and being adapted to be received and retained in a closed position with the undercut edge of the fixed member in an edge-to-edge to-edge engagement, the base member, cover member, and fixed member being formed of a sufficiently rigid material to minimize bowing on the closure thereby to ensure that a sample for testing and the testing element come into operative contact for effecting a test, and that a force is distributed substantially evenly over the cover member, and thereby further ensuring that, together with the hinge between the base member and the cover member, and with the closure means, the closure force is substantially equally distributed along the length of the closure means.

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.
