Abstract: A pump dispenser comprising a container having a neck (6) to which the pump is attached. A pump body (1) has an outward flange (91) through which it is supported on the edge of the container neck (6). A body/neck rotation stop mechanism (64,7) is provided by an interlock engagement between the pump body and the container neck, and has widely-spaced interlock projections (64) on the container neck (6), e.g. one or two projections, each having a circumferentially-directed abutment face (642). A series of spaced interlock teeth (71) projects down from the outward flange (91) of the pump body and these have respective abutment faces (711) to engage the neck projections and limit relative rotation of the pump body and neck. This can assure reliable action of a plunger-locking mechanism of the dispenser.

Abstract: A spray bottle assembly includes a bottle having a neck, and a spray head assembly having a base cap configured to removably attach to the neck. The base cap has a feature that rotationally locks the base cap relative to the neck to constrain the spray head assembly in a predetermined plane. A multi-label system for a spray bottle includes: at least one strip, the strip including connected labels with differing information printed on each side, each label including a ring for positioning on a neck of the spray bottle. A pumping mechanism for a spray bottle includes: a unibody plunger having a sleeve section that variably inverts and overlaps an end thereof thus defining an internal volume that varies with the disposition of the sleeve section relative to the end. A pivoting head section that allows servicing of functional seal components.

Abstract: Pump for dispensing a fluid product, having a piston having a pump chamber and an inlet and outlet valve. The outlet valve has an outlet valve element that slides inside the pump chamber. The pump chamber has a passage so that, at the end of actuation, the outlet valve element collaborates non-sealingly with the passage to open the outlet valve to expel product. The inlet valve has an inlet valve element sliding in a sleeve containing a spring pressing against the inlet valve element and against an end wall of the sleeve. The outlet valve element is formed by a component inserted with the ability to move into the piston, with the interposition of a second spring, the force exerted by the second spring is greater than the force exerted by the spring in the rest position, and less than the force exerted by the spring in the actuated position.

Abstract: Dispensing head (2) of a fluid product comprising: a manually actuable pusher (5) in relation to an insert, an elastic dispensing nozzle (10). When the pusher (5) is moved, the nozzle (10) switches from a closed position to an open position by deformation of the nozzle (10) under the effect of a release of a stress exerted by the pusher (5). The pusher (5) comprises a stop (54) and the insert (6) is provided with two deformable lugs (60) which cause a force on the pusher (5) such that the insert (6) exerts on the nozzle (10) a stress in the opposite direction to a stress exerted by the stop (54) on the nozzle (10), each lug (60) extending from a body (6a) of the insert (6) and having a distal end (60a) of the body, the said ends being surmounted and connected to each other by a connecting element 70.

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.
