  • Patent number: 4975587
    Abstract: The present invention relates to a container for storing and sterilizing a chopping board which mainly comprises a case, a scattering plate, a sterilizing lamp, a screen cover, a water collecting box, a supporting plate, a microswitch, a compression spring, a holding plate, a heating element and a bottom plate. The weight of the chopping board forces the supporting plate to contact the microswitch which in turn actuates both the sterilizing lamp and the heating element such that the ultraviolet light generated by the lamp together with the heat produced by the heating element can be scattered by the scattering plate to improve both sterilizing and drying efficacy. In addition, the present container has a compact overall volume and can be easily assembled because the utilized elements are simplified and the number of elements are significantly reduced.
