  • Patent number: 5425590
    Abstract: A disposable toothbrush apparatus is provided having a head, a bristle cluster extending from the head and a hollow handle for defining a toothpaste storage chamber connected to the head. A manually actuatable pump assembly mounted for axial displacement at the distal end of the handle storage chamber is adapted to cause a predetermined amount of toothpaste in the chamber to be fed via a conduit to a nozzle opening in a surface of the head at the base of the bristle cluster. In an alternative embodiment, a refillable cartridge containing a fresh supply of toothpaste and the self-contained pump assembly is adapted to be fitted to the hollow handle.

  • Patent number: 5265744
    Abstract: A tamper-proof cap for containers, bottles and the like comprising a first driven member and a second drive member concentrically mounted on the first member and having a window through which a visible signal may be observed by a viewer. A rupturable capsule containing signal media is supported on the first driven member and displays a signal of first characteristic through the window. Upon opening the cap by causing the drive member to engage the driven member, the capsule ruptures causing the signal media to display a signal of a second characteristic through the window indicative of the fact that an attempt had been made to open the cap. In an alternative embodiment, a lens mounted on the window portion of the drive member enables viewing of the signal characteristic when the containers bearing the caps of the invention are stored on a relatively high shelf.
