A dispenser pump for spraying a fine mist has a plunger (2) reciprocable in a pump body (3). The plunger has a head (4) and a stem (5). A closure (8) holds the pump in a container neck, and has an external decorative crimp sleeve (82). The plunger head has a matching external trim (72). A pump spring (7) is mounted outside the pump chamber (71), around the stem above the piston thereof. A pre-compression spring (75) acts to delay opening of the outlet piston seal until sufficient pressure builds in the pump chamber (71).

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.

The present disclosure provides a feeding container device, including a bottle body having a bottle inner cavity, a first cover body at least partially disposed inside the bottle inner cavity and fixedly connected to the bottle body, a second cover body at least partially disposed inside the bottle inner cavity and having a cover inner cavity, a sealing ring disposed inside the bottle inner cavity and blocking the cover inner cavity, and a feeding device fixedly connected to the second cover body, the second cover body is mounted to the bottle body, the sealing ring is detachably connected to the second cover body and abuts the first cover body; when the second cover body moves away from the bottle body, the first cover body causes the sealing ring to separate from the second cover body, and the first sealed chamber communicates with the second sealed chamber.

A foundation container includes an inner container main body (300) to which a pushing plate (371) is installed is fittingly coupled to an outer container main body (100), contents are injected into the supplementary container (370), an inner container blocking plate (350) is fixed to the inner container main body (300) to seal the inner container main body (300), a discharge pump (600) is formed on a center of the content blocking plate (350), a content diffusion member 9700) is coupled to the discharge pump (600), and an impregnation member (800) is coupled to an upper part of the content diffusion member (700).

A perfume bump valve needle unit has a valve needle, piston, spring and valve rod. A bump body unit has a valve needle unit, bump body, glass bulb and inner stopper. A bump head unit has an alumina press cap, spay chip and head cap. A valve rod external diameter between the inner piston and stopper has a Y-shaped spring with an end fixed to a recess and hold. A piston limit is at the valve needle head; an opposing needle bar sets into the rod center hole. A ring recess at the valve needle bar end snap-fits with a rod inner diameter ring buckle. The valve needle external diameter has an effluent trough from the ring recess to the head. A piston internal ring and rod external diameter fit and seal. A channel between trough and piston open when the rod, piston and valve needle move to the bulb.

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

A mist pump of a cosmetic container according to the present invention includes: a cap housing configured to be able to atomize contents by compressing external air introduced together with the contents in a cosmetic container and then discharging the contents in a whirlwind form by means of the compressed air; a piston housing; a compressing chamber formed between the cap housing and the piston housing; a piston formed to eject the compressed air and the contents while ascending; an opening and closing part that is formed between an inner surface of the piston housing and an outer surface of the piston, and through which the contents and the compressed air are ejected when the piston descends, and the external air is introduced into the compressing chamber when the piston ascends; and a pressurizing cap coupled to include an atomizing part that atomizes the contents by discharging the contents together with the compressed air in the whirlwind form through a nozzle passage formed in an upper end of the piston. Accordingly, the mist pump of the cosmetic container has the effects in that the mist pump may be used without being limited by the size of the cosmetic container, by virtue of external air compression, and a high level of stability can be achieved.

A trigger head for a dispensing device for at least two substances including a pumping system to compress the substances separately and simultaneously before dispensing.

A pump dispenser includes a dispenser head rotatable relative to a locking ring for a lock-down feature during shipment. The lock-down feature requires a greater torque to initially rotate the dispenser head from the lock-down position, and a lesser torque to further rotate the dispenser head to a use position. The lock-down feature incorporates an interference between the dispenser head and locking ring, either inside the dispenser head, on an outer periphery of the dispenser head, or between threads connecting the dispenser head and locking ring.

A pump having a piston (1) sliding in a body (3) having a chamber (5) between an inlet valve (11) and an outlet valve (12), an outlet valve element sliding during actuation in the chamber (5), and a passage (40) wherein, at end of actuation, the outlet valve element (39) cooperates in a non-sealing manner with the passage to open the outlet valve. The inlet valve has an inlet valve element (10) that slides after closure in a sleeve (9) with reduced diameter and a spring (20) bearing on the inlet valve element and on a bottom of the sleeve. The spring (20) returns the piston into its rest position. The sleeve (9) has an inner diameter of less than 4.2 mm. The spring (20) has a force of at least 20 N, so that the pump delivers the fluid product at a pressure (P) of at least 15 bars.
