Abstract: A device (20) for cleaning dentures broadly includes a cup (21) adapted to hold a liquid (L), and a strainer (29) associated with the cup. The cup as an upper peripheral lip (24). The strainer (29) is a basket-like member having a foraminous bottom (30). The strainer is adapted to be lowered into the cup to submerge a denture contained within the strainer in the liquid. The strainer has at least one hook (35) that is adapted to selectively engage the cup lip (24) such that the strainer may be held in an elevated position relative to the cup such that liquid on the denture may drain into the cup.

Abstract: A tooth bleaching tray (20) broadly includes a U-shaped trough-like member (21) having a central arcuate portion (22) and having an extension portion (23, 24) continuing from either end thereof and terminating in a distal end (25, 26). The tray has an outer wall (28) adapted to face toward the outer surface of a person's teeth, an inner wall (29) adapted to face toward the inner surface of such person's teeth, and a bottom surface (30) joining the lower margins of the inner and outer walls. A thin flexible wall (31, 32) is located at each extension portion distal end (25, 26) and joins the margins of the inner and outer walls and the bottom surface. This flexible portion is adapted to conform to the shape of such person's rearwardmost molar without deformation of the trough-like member, and functions as a dam to prevent bleaching composition from flowing out of the trough-like member through the distal ends.

Abstract: A toy musical instrument of the type commonly known as a kazoo having an open-ended turret section, a resonating membrane positioned within the turret section and a retainer member for installation within the turret section and for releasably securing the membrane within the turret section utilizes a turret section having a plurality of protuberences and a retainer member defining an embossment which cooperates with the protuberences to secure the retainer member in a snap-fit relationship with the turret section when the retainer has been inserted a preselected distance through the open end of the turret section. The embossment and the protuberences are so shaped to permit the retainer and the turret section to be disassembled from snap-fit relationship only if the retainer body is positioned in a preselected rotational orientation relative to the turret section.
