A refillable fluid dispenser having a fluid reservoir (1) with a bottom wall (12) provided with an opening (13); a filling valve (2) mounted in the opening and that includes a movable member (26) and a valve seat (21); a dispenser member (4) having an actuator rod (44) and a vent system, the actuator rod (44) movable axially between a rest position and a depressed position and the vent system closed in the rest position and open in the depressed position; and a pusher (6) mounted on the actuator rod (44). The fluid dispenser includes an abutment mechanism (76) for holding the pusher (6) when pressure exerted on the filling valve (2) is transmitted to the dispenser member (4) so as to move the dispenser member body (41) relative to its actuator rod (44) to bring it into its depressed position in order to open the vent passage.

The embodiments of the present disclosure provide a spray bottle with storage function, which includes a spray bottle body. The spray bottle body is provided with a storage box, allowing liquid and other solid seasonings to be separated but be contained together. The storage box for containing the solid seasonings is equipped with a box cover exposed outside the spray bottle body. When sprinkling the seasonings, it is only necessary to open the corresponding box cover without separating the storage box from the spray bottle body. It is more convenient to use, occupies less space and is easy for storage.

Disclosed are self-sealing actuators and pumps for distributing fluids such as personal care products. The actuator can include a nozzle having an outlet that is opens and closes via movement of a plug. A limit rod is configured to engage with the plug and upon actuation the assembly opens a passage for the fluid to flow through an inner channel of the limit rod and to the outlet. Upon de-actuation, the assembly closes the passage sealing the fluid within a closed environment to prevent degradation and caking. Actuators and pumps as described protect the performance of active ingredients within the fluid and prevent the nozzle and outlet from blocking with dried or caked fluid.

A spray dispenser is provided, the spray dispenser comprising a container for holding a liquid to be dispensed and a dispensing assembly for extracting liquid from said container, the dispensing assembly comprising a pressure-relief valve for release of excessive pressure in the container and a filter arranged to permit egress of gas through the filter, inhibit egress of liquid from the container and to inhibit ingress of contaminants into the container through the pressure relief valve. A dispensing assembly for use is a spray dispenser is also provided.

The present invention is directed to airless storage and dispensing systems that include a pump or dispensing package pre-filled with a topical semi-solid imiquimod pharmaceutical formulation (pump systems) and methods for storing and dispensing from the pump systems a plurality of precisely measured and uniform unit doses of a topical semi-solid imiquimod pharmaceutical formulation, and more particularly to pump systems, pre-filled with a topical imiquimod pharmaceutical cream and methods for delivering multiple precisely measured unit doses of a topical imiquimod pharmaceutical cream, and methods for using a controlled delivery pump system to store and dispense a plurality of consistent and precisely measured unit doses of a topical imiquimod pharmaceutical cream for use in topically treating a dermal and mucosal-associated condition, such as, external genital warts and/or perianal warts (EGWs), actinic keratosis or actinic keratoses (AK or AKs) and superficial basal cell carcinoma (sBCC).

Embodiments of lost motion foam pumps are disclosed herein. One exemplary embodiment includes a liquid chamber, a liquid piston movable in the liquid chamber, an air chamber and an air piston movable in the air chamber. The air piston is linked to the liquid piston. A connector is linked to the air piston or the liquid piston. The connector includes an engagement member for connecting to an actuator of a foam dispenser. Movement of the actuator in a first direction moves the liquid and air pistons to contract the liquid chamber and the air chamber. Movement of the actuator a first distance in a second direction does not move the liquid piston or the air piston; however, continued movement of the actuator a second distance in the second direction moves the liquid piston and the air piston and expands the liquid and air chambers.

The present invention relates to a fixed quantity discharge device for a liquid container that includes a spuit pipe formed so as to suck contents without being exposed to the contents stored in a container body such that contamination of the spuit pipe due to the contents can be prevented; and a piston rising according to a use of the contents within the container body so as to minimize the remaining contents within the container body.

A cosmetic container having a storage container for housing a liquid- or gel-form basic cosmetic and a granulated cosmetic having a different function from the basic cosmetic, an airless pump on top of the storage container for discharging the mixed cosmetics from the storage container, and pulverization apparatus including a pulverizing member, a first pulverizing mesh and a second, finely pulverizing mesh positioned in a plurality of stages in a discharge pathway within the airless pump to cause the granulated cosmetic in the mixed cosmetics to be finely pulverized in a plurality of stages, with multistage smashing and fine pulverization of the granulated cosmetic in the pump such that discharge of the cosmetic is thereby performed smoothly when the cosmetic is used.

The present invention discloses a pressing pump and a liquid container. The pressing pump comprises a pump body, a one-way valve, a valve stem assembly, a pressing head and an annular part. The pump body is provided with an accommodating cavity. The annular part is inserted into the accommodating cavity, and the outer circumference of the annular part sealably abuts against an inner wall of the accommodating cavity. The pressing head is provided with a second channel which communicates with the first channel. The second channel has a first opening which is disposed on the side wall of the pressing head close to the pump body and is located at an outer side of the annular part. The pressing pump provided in the present invention can reduce the circumstances in which external moisture enters the interior of the pump body, and improve the waterproof performance.

A full-plastic trigger spray pump, wherein a lower part of the pump body is connected to a locking cover, a liquid spray channel is in the pump body, a nozzle is provided at an outlet of the liquid spray channel, a liquid outlet channel is communicated with the liquid spray channel, a liquid guide chamber is provided on the liquid outlet channel and a liquid inlet channel, the upper part of the liquid guide chamber is in communication with the liquid outlet channel by a normally open port, a pumping piston is in the liquid guide chamber, a trigger capable of driving the pumping piston is hinged onto the pump body, an elastic arm capable of driving the trigger is provided thereon, a lateral one-way valve adapted to open during the return movement of the pumping piston enables the liquid guide chamber to communicate with the liquid inlet channel.
