Embodiments of the invention include a poly-ketonic cosmetic package for fluid dispenser systems.

A discharge device including a pump disposed to a container body in which contents are stored and which includes a discharge head provided with a discharge hole formed therein; a mounting cap; a support portion; and a press-down member. By rotating the press-down member, the discharge head is moved downward and the contents are discharged from the discharge hole. The discharge device includes a stopper which is movable between a restricted position where the downward movement of the discharge head is restricted and a non-restricted position where the downward movement of the discharge head is allowed.

A device for dispensing fluid products includes one or more containers, each storing one fluid product, a unique pump provided with a dosage chamber enclosing a dose of mixture of the fluid products, and including an actuating member, and a manifold associating the pump to the containers for dispensing the fluid products. The manifold includes one or more hollow tubes each extending into a container and forming a channel for the flow of the fluid product from the container towards the pump. As well, the tubes of the manifold are rigid and at least one tube of the manifold includes means for regulating the volumetric ratio of the fluid product flow, these regulating means being integrated inside the rigid tube.

A fluid substance container including a collar featuring a passage and a pair of laminated film sheets heat-welded along perimetral welding lines so as to form a bag, the pair of sheets also being heat-welded to the collar so that the passage in the collar provides access to interior of the bag; the collar features a cup-shaped part in which the passage is formed, there being a sealing lip extending from a bottom of the cup-shaped part, the sealing lip being formed integrally with the collar and intended to cooperate in an air-tight manner with an outer surface of the body of a hermetic pump which may be housed, at least partially, in the collar.

[Object] To provide a pump dispenser which allows accurate determination of a direction of spraying of liquid without a nozzle part moving toward a higher or lower position and, furthermore, whose trigger is excellent in operability. [Solution] The present invention is directed to an F valve attachment structure for, in a pump dispenser that causes a piston part to slide to apply pressure to liquid inside a cylinder part including an F valve and causes the liquid to squirt out from a nozzle part via an S valve, attaching the F valve to the inside of the cylinder part with use of a valve stopper, the F valve including: a valve body part; and a rod-like part extending upward from the valve body part, wherein the valve body part has a plurality of guide pieces and check pieces therearound, the valve stopper has a hole and notches in a ceiling part of the valve stopper, the notches allowing the guide pieces to pass through the notches, the valve stopper is fixable inside the cylinder part, when the valve body part of the F valve is inserted through the hole of the valve stopper, the check pieces are allowed to elastically pass through the hole, and after insertion, the check pieces of the F valve come into contact with the ceiling part of the valve stopper to be retained.

A trigger-type liquid ejector includes an ejector main body and a nozzle member. The ejector main body includes a vertical supply pipe, an ejection barrel and a trigger mechanism; and the trigger mechanism includes a main piston and a main cylinder. In the trigger-type liquid ejector, the ejector main body includes a connection tube, a closing-off plug, a reservoir cylinder, a reservoir plunger and a reservoir valve, and the ejection barrel extends forward from the reservoir cylinder.

A discharge device including a pump disposed to a container body in which contents are stored and which includes a discharge head provided with a discharge hole formed therein; a mounting cap; a support portion; and a press-down member. By rotating the press-down member, the discharge head is moved downward and the contents are discharged from the discharge hole. The discharge device includes a stopper which is movable between a restricted position where the downward movement of the discharge head is restricted and a non-restricted position where the downward movement of the discharge head is allowed.

A device for dispensing fluid products includes one or more containers, each storing one fluid product, a unique pump provided with a dosage chamber enclosing a dose of mixture of the fluid products, and including an actuating member, and a manifold associating the pump to the containers for dispensing the fluid products. The manifold includes one or more hollow tubes each extending into a container and forming a channel for the flow of the fluid product from the container towards the pump. As well, the tubes of the manifold are rigid and at least one tube of the manifold includes means for regulating the volumetric ratio of the fluid product flow, these regulating means being integrated inside the rigid tube.
