Title
(EN) A TRIGGER-TYPE DISPENSING HEAD FOR A DISPENSING DEVICE FOR PASTY PRODUCTS SUCH AS TOOTHPASTES
(FR) TÊTE DE DISTRIBUTION À GACHETTE POUR UN DISPOSITIF DISTRIBUTEUR DE PRODUITS PÂTEUX TELS QUE DES DENTIFRICES
Abstract
(EN) A dispenser (1) for pasty products such as toothpastes comprises a fixed head (40) having a dispensing duct (42) dispensing the product, a pump (28) with an elastically deformable cap (54), a manually-actuated actuator (80), a separating wall (24) with a suction inlet (24a), and a suction valve that cooperates with the delivery outlet (24a). The suction valve comprises a valve body (73) and a plurality of tabs (77', 77'') that bend and open the suction inlet (24a) in the product suction phase, and close the suction inlet (24a) in the product dispensing phase.
(FR) Distributeur (1) de produits pâteux tels que des dentifrices, comprenant une tête fixe (40) ayant une conduite de distribution (42) qui distribue le produit, une pompe (28) ayant un couvercle (54) pouvant subir une déformation élastique, un actionneur manuel (80), une paroi de séparation (24) ayant un orifice d'entrée (24a) pour aspiration, et une soupape d'aspiration qui coopère avec l'orifice de distribution (24a). La soupape d'aspiration comprend un corps de soupape (73) et une pluralité de languettes (77', 77") qui plient et ouvrent l'orifice d'entrée pour aspiration (24a) dans la phase d'aspiration du produit, et ferment l'orifice d'entrée pour aspiration (24a) dans la phase de distribution du produit.
