Abstract: A mouthguard includes an integrally molded tray having upper and lower portions joined by a hinge along an inner portion of the tray that defines an open-sided channel gap between the upper and lower tray portions. Shock forces tending to deflect the lower portion of the tray toward the upper portion are countered by a moment resistance of the hinge as the channel gap between the upper and lower tray portions closes. Additional energy absorption is provided by a cushion liner attached to an inner surface of the tray that prevents contact between the upper and lower tray portions, as well as an air cell defined by an occlusal pad attached to the lower tray portion. Embodiments include a detachable tether that is received within a tether mount incorporated within the mouthguard.

Abstract: A manually operated object dispenser includes a cover that rotates relative to a base allowing easy access to a storage compartment and allowing stored objects to be dispensed. A rotatable reminder wheel disposed beneath the cover automatically advances to a next position with each use, exposing indicia through a window on the cover. The dispenser comprises two sets of ratchet prongs and teeth: the first set engaged when the cover is rotated to an open position, while the second set is engaged when the cover is subsequently rotated to a closed position. Accordingly, the reminder wheel moves a predetermined distance to incrementally expose indicia through the window with each object that is dispensed. One embodiment of the dispenser includes a storage tray for storing objects and an access port through which the objects are dispensed. Another embodiment of the dispenser is attached to an external storage compartment.

Abstract: A contact lens case includes manually adjustable counters or time indicators on the left and/or right well caps utilizing voids, cut-outs or apertures to define indicia used to represent time intervals for lens replacement, maintenance, or other activities. A rotatable time indicator dial is connected to the top of the cap in a first embodiment, whereas a rotating indicia dial is confined under a windowed cover in a second embodiment. The dials are indexed by a paw or pin that seats into recesses in the disc and along the centerline of the indicia desired to be accented, windowed or illuminated. Accent of indicia voids by illumination can be by an exterior direct or diffused light source, or internally from chemical luminance or other means.
