Abstract
The invention relates to saucer-type handle components (5, 6) that pertain to a hollow handle and are produced in several steps. Said handle is used for a toothbrush. Said components are joined together and are inserted into an injection mould (25). A synthetic material, preferably a thermoplastic elastomer, is injection-moulded around the mould-parting line between the handle components (5, 6) in said injection mould (25). The connection seam (22) thus produced holds the two handle components (5, 6) together in a nondetachable manner and seals the hollow space (13) which is formed by the handle components (5, 6).
