Abstract
A closure and a device for use with a closure are described. The closure includes a first member having an interrupted 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 interrupted beveled edge retained by the undercut edge. A test device can include such a closure and can also include a hinge between the first and second members. Test elements, such as a chromatographic medium, an absorber, an applicator, or a sample application zone, can be disposed on the first member and/or the base member and can be brought into opposition by closing the first member with the closure. The beveled edge is interrupted by one or more uncut portions or bridges. A testing device according to the present invention can perform a number of types of immunoassays, including unidirectional assays, bidirectional assays, and assays employing a split flow path.
