Abstract: A pump for dispensing a fluid, has a pump head , a piston body with a piston, a pump chamber limited by a pump chamber body, an inlet valve and an outlet valve, the piston being moveable by respective movement of the pump head between an upper starting position and a lower end position. A return stroke force for a return stroke from the lower end position into the upper starting position is provided by a bellows, formed by two bellows arranged one above the other, Each of the bellows is folded up, when moving the pump head into the lower end position, by exerting a compression force on the pump head, the first bellows receiving the compression force by direct engagement with the pump head, the second bellows receiving the compression force only by engagement with the first bellows.

Abstract: The present invention relates to a dispensing device, comprising:



a connecting member to be mounted on the opening of a container,
a piston,

a cylinder body in which the piston is arranged so as to define a metering chamber between the piston and the cylinder body, the piston comprising a dosing inlet and a dispensing opening, the cylinder body being slidable along the piston,
an inlet check valve provided to open the dosing inlet when subjected to negative pressure,
an outlet check valve provided to open the dispensing opening when subjected to positive pressure.






The outlet check valve comprises a membrane with a sealing lip adapted to slide against the inner axial surface of the cylinder body.

Abstract: The invention relates to a closure device comprising a closure wall having a communication conduit passing through it and intended to close the opening of a container of a product and a stopper movable in the duct. The stopper comprises a cavity open on one side of the wall, closed by a bottom and comprising at least one lateral opening. In the closed position, this bottom closes the conduit, and in the open position, the side opening(s) and said bottom exit the conduit, the conduit thus being open in fluid communication through the stopper. The invention also relates to a product refill comprising a container closed by this closure device. It also relates to a dispensing device comprising this refill and a dispensing head.
