Abstract

L'invention concerne une boule en matière plastique. La boule est creuse et est composée de deux pièces de moulage distinctes 1 et 2 fixées l'une à l'autre par encliquetage, et portant chacune une partie 3 ou 4 de la surface extérieure visible de la boule. Les pièces 1 et 2 comprennent d'une part une paroi bombée 7 ou 8 et d'autre part un manchon d'accouplement 9 ou 10. Les parois bombées sont d'épaisseur constante. Le manchon 9 s'ajuste à l'intérieur du manchon 10. Application : boule de bel aspect, et d'un bas prix de fabrication.
