A dispensing pump (10) includes a removable chaplet (28) to facilitate removal of the internal metal spring components (44) for recycling. The dispensing pump (10) includes an accumulator (12) having an upper rim wall (24). The chaplet (28) is coaxially snap received about the rim wall (24) of the accumulator (12). The chaplet (28) has a body portion (30) received within the rim wall (24), and an outer wall (32) received outside of the rim wall (24). The outer wall (32) has a frangible wall portion (48) and a pull tab (50) at a terminal edge thereof. A dispensing head (36) with a piston stem (38) and spring (44) are coaxially guided within the chaplet (28) and accumulator (12). When the container is empty, the user pulls on the pull tab (50) to sever the frangible elements, releasing the chaplet (28) and allowing easy removal of the dispensing head (36) and the metallic spring component (44).

A lotion pump includes an internally threaded sleeve; a spring-loaded dip tube including an annular first flange on an outer surface, and an internal shoulder; a first housing including a tapered head, a chamber spaced from the tapered head, a tunnel communicating between the tapered head and the chamber, overflow openings on the tunnel, and first external threads on an outer surface of the chamber; a check valve; a second housing including an open first chamber member, an open second chamber member, a channel communicating between the first chamber member and the second chamber member, second external threads, and an annular second flange on an outer surface; a support including an annular third flange on an outer surface, and an second opening; a spring-loaded valve; and an internally threaded cup including an annular fourth flange on an outer surface, and a second hole through a second end.

A hand-held integral airbrush includes a shell provided with a grab handle, wherein an upper accommodating cavity and a lower accommodating cavity are formed in the shell, an airbrush assembly is arranged in the upper accommodating cavity of the shell, and an air pump assembly is arranged in the lower accommodating cavity of the shell and is used for pumping compressed air into the airbrush assembly. The hand-held integral airbrush further includes a switch part, as well as an operating button which includes a first control part and a second control part. According to the hand-held integral airbrush, an air pump and an airbrush are integrated in the ergonomically designed grab handle, and the air pump and the airbrush are controlled by the trigger-type operating button to operate, so that the hand-held integral airbrush is more convenient to hold and operate.

An e-liquid bottle includes a main body for receiving e-liquid therein, and an e-liquid injecting member mounted on a bottleneck of the main body. The e-liquid injecting member includes a sleeve, a chamber formed inside the sleeve for storing e-liquid therein, a single valve connected between the bottleneck and an e-liquid suction portion of the chamber for controlling the e-liquid flow to the chamber, a piston installed in an e-liquid feeding portion of the chamber, an e-liquid guiding pipe formed on the piston and extending into the sleeve, a base mounted on the sleeve to engage with the e-liquid pipe and driven by the piston move back and forth along the chamber to control the pressure in the chamber, an e-liquid feeding tube connected to an e-liquid outlet of the e-liquid guiding pipe. An interval is formed between the piston and the base so that the piston can move along the interval towards the chamber to separate the e-liquid guiding pipe from the base and connect an e-liquid inlet of the e-liquid guiding pipe with the chamber.

In a dispenser for dosing of at least one component received in a receiving compartment, a valve device, forming an inlet valve and an outlet valve associated with an outlet opening, is formed of at least two valve elements.

An actuator is provided. The actuator includes a nozzle; a valve; a conduit in fluid communication with the valve at one end portion and in fluid communication with the nozzle at an opposite end portion; and a trigger operatively connected with the valve, wherein the trigger includes a first zone and a second zone, wherein the first and second zones are independently movable about a common axis.

A micro pump vessel has an outer vessel on one side of which a button is formed and an outer vessel lid which is hinge-coupled to one side of the outer vessel to be opened and closed. In the vessel, a first and a second pistons are installed on an upper surface of cosmetic contents, and thus, when the cosmetic contents are pumped and used by the operation of a micro pump, the first and the second pistons lower to exhaust all the cosmetic contents so as not to discard the remaining cosmetic contents.

A foam dispenser has a foam-generating pump (1) mounted on a container (100) to hold liquid. The pump (1) has a liquid intake conduit with a ball valve (27) and an air intake conduit (45) provided partly by a jacket component (4) fitting around the pump body (2) with clearance. The pump has structure defining a mixing zone (50) for mixing air and liquid, a foam chamber (28) for holding foam received from the mixing zone, and a discharge conduit leading from the foam chamber to a discharge outlet (36). The mixed air and liquid pass through a permeable foam regulator mesh (54). One or more air inlets (47) lead into the mixing zone (50) from the air intake conduit (45). A liquid inlet in the form of a restricted jet orifice (89) leads into the mixing zone (50) from the liquid intake conduit, upstream of the inlet ball valve (27). A regulator mesh (53) is also provided between the liquid inlet and mixing zone.

A pre-compression pump includes a main body, a first piston assembly movably mounted in the main body, a head assembly on a top of the first piston assembly, a second piston in the first piston assembly, and a second spring supported between the second piston and the first piston assembly. A water storage sump is disposed between the main body and the first piston assembly. A water outlet channel is disposed in the inner part of the first piston assembly. The water outlet channel is connected to the water storage sump and a nozzle of the head assembly. The second piston has an ejector pin portion for sealing the water outlet channel.

Pump systems and methods are disclosed for removing liquid for hand-portable containers. The pump systems include a moveable piston housed in a main chamber and inlet and outlet valves located at one end of the main chamber, where the inlet and outlet valves open and close in response to movement of the piston.
