MANUFACTURE OF TOILETS

摘要

The disclosure relates to a method of manufacturing a component for a toilet such as a bowl unit or a holding tank for a portable toilet. The unit or task is formed from first and second mouldings in a thermoplastic material which are adapted to fit together in a joint plane to form an enclosure. The mouldings define respectively a continuous channel and a continuous tongue capable of being received in the channel for forming a joint between the mouldings. A sealing strip is provided and is adapted to be received in the channel and is substantially co-extensive with the channel. The strip comprises a thermoplastic material capable of fusing with the termoplastic material from which the mouldings are formed and having magnetically excitable particles dispersed therein. The sealing strip is positioned in the channel and the mouldings are assembled to form the bowl unit or tank with the tongue of one moulding engaged in the channel of the other. The sealing strip is then subjected to the effect of a high-frequency magnetic field having characteristics selected to excite the particles of the sealing strip to an extent sufficient to cause the strip to fuse with the channel and tongue and form a liquid-tight seal between the mouldings.
