Abstract
The moveable dam structure of an adjustable measuring device such as a spoon or scoop has a structure molded of a single material with thin flexible curved edges which fit into the internal walls of the housing to provide increased surface contact without co-molding or other assembly of a separate edge seal onto the moveable dam. The moveable dam is molded in a single step of a single thermoplastic material to give the dam a tapered cross-sectional shape with the inner portion thicker than the outer edges, with curved edges forming angles substantially different from 90° when bearing against the internal walls of the measuring container.
