Abstract

Tamis formé d'un corps cylindrique (1) dont le fond est occupé par une grille (2). Le corps (1) est une pièce unique en matière plastique moulée ayant une paroi cylindrique circulaire (11) avec une collerette basse (12) et une collerette haute (13) délimitant entre elles un logement périphérique dans lequel est tenue la grille (2). La collerette basse (12) est formée d'une succession de segments bas (121) sur lesquels repose le bord de la grille (2). La collerette haute (13) est formée d'une succession de segments hauts (131) correspondant en vue en plan aux intervalles (122) entre les segments bas (121) de la collerette basse (12). Le bord de la grille (2) reposant sur la collerette basse (12) est coiffé par la collerette haute (13).Screen formed by a cylindrical body (1), the bottom of which is occupied by a grid (2). The body (1) is a single piece of molded plastic material having a circular cylindrical wall (11) with a low flange (12) and a high flange (13) delimiting between them a peripheral housing in which the grid (2) is held. . The bottom flange (12) is formed by a succession of bottom segments (121) on which the edge of the grid (2) rests. The upper flange (13) is formed by a succession of high segments (131) corresponding in plan view to the intervals (122) between the low segments (121) of the low flange (12). The edge of the grid (2) resting on the low flange (12) is capped by the high flange (13).
