Abstract: Push actuated double fluid dispenser (1), comprising a container (2) having a first cavity (4a) and a second cavity (4b) separated from the cap first cavity (4a), and a dispensing pump device (6) in a general form of a cap assembled to the container over the first and second cavities, the dispensing pump device comprising a base part (7) and a cap part (8) including a pump mechanism (16) comprising an elastic flexible pump membrane (18) manually movable from an uncompressed state to a compressed state. The pump mechanism (16) further comprises a separating wall (20) extending from an underside of the pump membrane (18) and inserted into a slot in the base part, the separating wall separating a first pump chamber (22a) from a second pump chamber (22b), both first and second pump chambers provided in a volume below the pump membrane (18), the first pump chamber connected fluidically to a first inlet channel (10a) and a first outlet channel (11a), the second pump chamber connected fluidically to a second inlet channel (10b) and second outlet channel (11b), the inlet channels fluidically interconnecting the respective first and second cavities to the respective first and second pump chambers, valves (13) being positioned between the inlet channels and the pump chambers configured to allow fluid flow only in the direction from the cavities to the respective pump chambers, and the outlet channels interconnecting the pump chambers to an outlet nozzle (12) of the dispenser, outlet valves (24a, 24b) being positioned in the outlet channels configured to allow fluid flow only in the direction from the pump chambers to the outlet nozzle.

Abstract: A pump for dispensing a fluid, has a pump head, a piston with a piston body, a pump chamber provided by a pump chamber part, an inlet valve and an outlet valve. The piston body is moveable relative to the pump chamber. The piston body is tube-like, providing a channel for delivering the fluid from the pump chamber via the outlet valve to an outlet opening in the pump head. The outlet valve is a valve body cooperating with a sealing rim formed by an opening in an outlet channel of the pump head. The piston body has a sealing lip for with an inner surface of the pump chamber body. The pump head is moveable relative to the piston body providing an opening stroke for the outlet valve, wherein the valve body moves axially in the opposite direction into a part of the outlet channel above the valve body.

Abstract: A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.
