Patent

CA 2425110

There is provided a method for producing a musical and/or toy shaker made with a thermoplastic material. The shaker is injection or blow molded in the form of a substantially continuous body that defines an internal, hollow portion (20). In addition, the body defines a hole or vent (30) that communicates with the hollow portion, thus allowing a fill material (40) to be passed through the vent and deposited in the hollow portion. Significantly, the body is formed with a duct surrounding the vent. Upon filling the hollow portion, the duct is melted in order to seal the vent.

L'invention concerne un procédé de fabrication d'un hochet utilisé à des fins musicales ou comme jouet, fait en matière thermoplastique. Ce hochet est moulé par injection ou par soufflage en forme de corps pratiquement continu qui définit une partie interne creuse (20). De plus, le corps définit un trou ou un évent (30) qui communique avec la partie creuse, permettant ainsi à une matière de remplissage (40) d'être introduite par l'évent et déposée dans la partie creuse. Il est préférable que le corps soit doté d'un conduit qui entoure l'évent. Après remplissage de la partie creuse, le conduit est fondu afin d'obturer l'évent.
