  • Apparatus with a housing provided with a synthetic resin wall portion with a synthetic resin panel provided thereon
    Patent number: 6305083
    Abstract: A housing (1) of an apparatus has a plastics wall portion (2) provided with a plastics panel (4). To make a reliable and visually acceptable connection of the panel (4) to the wall portion (2), the panel is fixed to the wall portion by means of an induction welding process. In this way the connection is resistant to chemical compounds like lotions. Therefore a metal element (8) of electric conducting material having the shape of a closed loop wire is inserted between the wall portion (2) and the panel (4) and subsequently an electromagnetic field is applied in close proximity to the element. Preferably such panel (4) can be used to cover an opening (11) in the wall portion (2) for a display (10) and/or a switch (15) function. To make the housing watertight the element (8) between the panel (4) and the wall portion (2) should surround the opening (3,11).
