  • Publication number: 20020112741
    Abstract: A hand-held scrubbing device for cleaning a surface includes a waterproof casing having an interior area and an exterior area. The interior area has an electromechanical motor, a battery joined to the electromechanical motor, and a dispensing chamber joined to a dispensing mechanism. The exterior area has an orifice joined to the dispensing mechanism, a dispensing activator joined to the dispensing mechanism, and a scrubbing surface joined to the electromechanical motor. When the dispensing chamber is filled with a cleaning composition and when the dispensing activator is activated, the dispensing mechanism expels a portion of the cleaning composition from the waterproof casing, via the orifice. Furthermore, the electromechanical motor provides a mechanical action to the scrubbing surface. A method for cleaning an item employs such a hand-held scrubbing device. A cleaning kit includes such a hand-held scrubbing device and a cleaning composition.

  • Patent number: 5110004
    Abstract: In the closable lid assembly comprising two elements joined together by means of a hinge, provision is made for the first element or lid to have a channel-shaped peripheral cavity designed to receive the peripheral relief of the second element, in the form of a small frame, which has a flat flange designed to delimit the opening of the packaging onto which the assembly is applied. Either or both the flanks of the peripheral relief have corrugations which cooperate with the vertical walls of the channel provided in the movable lid element, such corrugations forming an airtight seal between the two elements of the assembly. In order to improve further the airtightness of the closure, a gasket is also provided on the bottom of the cavity and comes into abutment against the relief of the small frame.
