Patent

CA 2746219

A dispenser includes a housing that holds first and second refill units, each including a product container and a valve assembly that receives prod-uct from the product container. An actuator mechanism associates with the first re-fill unit and is actuated to force air into the associated valve assembly and dispense product from the valve assembly until such time as the product container associat-ed with that valve assembly is empty. When empty, a float valve of the valve as-sembly prevents the actuation of the actuator mechanism and forces the actuator mechanism to associate with the second refill unit. While so associated, the first re-fill unit can be replaced, thus, helping to ensure that the dispenser does not run out of product.

Un distributeur comprend un logement qui contient des première et seconde unités de recharge, chacune comprenant un récipient de produit et un ensemble clapet qui reçoit le produit provenant du récipient de produit. Un mécanisme actionneur est associé à la première unité de recharge et est actionné pour forcer lair dans lensemble clapet associé et distribuer le produit depuis lensemble clapet jusquau moment où le récipient de produit associé à cet ensemble clapet soit vide. Lorsquil est vide, un clapet à flotteur de lensemble clapet empêche lactionnement du mécanisme actionneur et force le mécanisme actionneur à sassocier à la seconde unité de recharge. Lorsque ceux-ci sont associés, la première unité de recharge peut être remplacée, contribuant ainsi à sassurer que le distributeur nest pas à court de produit.
