Title
(EN) MOULD FOR CONTAINER, COMPRISING A MOULD BASE PROVIDED WITH A CENTRAL WELL, AND A STRETCHING ROD WITH A HEMISPHERICAL END
(FR) MOULE POUR RECIPIENT, COMPRENANT UN FOND DE MOULE MUNI D'UN PUITS CENTRAL, ET UNE TIGE D'ETIRAGE A EXTREMITE HEMISPHERIQUE
Abstract
(EN)
A mould for a container (1), that comprises: - A mould base (19) having: o a peripheral face (21), o a central dome (23), and o a central well (24) formed in the dome (23) and extending along a frustoconical sidewall (25) from a top edge (26) of the dome (23) having a top diameter, to a bottom (27) having a bottom diameter smaller than the top diameter; - A stretching rod (29) that ends with a hemispherical distal end (31) having a radius (R), the value of which is between that of the bottom radius and that of the top radius of the central well (24) and which, when the rod (31) is in the bottom position, is separated from the sidewall (25) of the central well (24) by a distance (E1) smaller than the distance (E2) that separates it from the bottom (27) of the well.
(FR)
Moule pour un récipient (1), qui comprend : - Un fond (19) de moule ayant : o une face (21) périphérique, o un dôme (23) central, et o un puits (24) central creusé dans le dôme (23) et qui s'étend suivant un flanc (25) tronconique depuis un bord (26) sommital du dôme (23) ayant un diamètre haut, jusqu'à un fond (27) ayant un diamètre bas inférieur au diamètre haut; - Une tige (29) d'étirage qui se termine par une extrémité (31) distale hémisphérique ayant un rayon (R) de valeur comprise entre celle du rayon bas et celle du rayon haut du puits (24) central et qui, en position basse, de la tige (31), est séparée du flanc (25) du puits (24) central d'une distance (E1) inférieure à la distance (E2) qui la sépare du fond (27) du puits.
