Abstract

Distributeur de savon ou de désinfectant comprenant un boîtier et un réceptacle pour recevoir une unité de recharge. L'unité de recharge comprend un récipient avec un col et une fermeture, le col se situant au niveau de la position la plus basse du récipient lorsque l'unité de recharge est insérée dans le distributeur. Le réceptacle a une plaque supérieure avec une ouverture à travers celle-ci. Un bras de verrouillage mobile entre une position déverrouillée et une position verrouillée et un élément de sollicitation sont également inclus. L'élément de sollicitation sollicite le ou les bras de verrouillage vers la position verrouillée. Le distributeur comprend en outre un élément de retenue de verrou et un élément de libération de verrou. Lorsque le bras de verrouillage est déplacé de la position verrouillée à la position déverrouillée, l'élément de retenue de verrou verrouille le bras de verrouillage dans la position déverrouillée et, lorsqu'une unité de recharge est insérée dans le réceptacle, l'élément de retenue de verrou se déverrouille du bras de verrouillage.
