  • Patent number: 8378323
    Abstract: The sterilizing toybox apparatus addresses illness risk, especially with children, by providing UV light sterilization within. UV lighting is offered both above and beyond toys within the apparatus. A time-release latch ensures exposure for a time determined to be optimal for UV exposure of contents. The apparatus provides UV lighting both in the bottom of the chest and in the lid. The clear shelf above the lower UV bulbs is in communication with the vibrator that jostles any toys so that full UV exposure is ensured. Reflective material distributed fully within the chest further guarantees full exposure of contents to sterilization. Additionally, the optional mesh basket is selectively suspended within the chest.
