A hand pump design that utilizes an actuator with a folding nozzle suitable for use in e-commerce is presented. The folding nozzle equipped pump actuator forms part of a hand pump assembly which incorporates a pump body assembly comprising upper and lower pump bodies and a sliding collar which controls the inlet of fluid to be dispensed into fluid passages in the pump assembly and subsequently into the pump actuator. The hand pump further includes upper and lower check balls to prevent back flowing of the fluid to be dispensed into the dispenser bottle.

A fluid dispenser for containing and dispensing metered amounts of fluid that includes a reservoir for containing fluid and a chamber positioned substantially within the reservoir for containing a quantity of the fluid. The fluid dispenser additionally includes a piston that is moveable within the chamber to draw fluid into the chamber when the piston is moved in a first direction with respect to the chamber, and to discharge fluid from the chamber when the piston is moved in a second direction opposite the first direction. Further, the fluid dispenser includes a user-manipulatable control coupled to the piston and rotatable about an axis to select one of at least two different metered quantities of fluid to be dispensed. The user-manipulatable control is further movable to move the piston relative to the chamber along the axis to selectively dispense the selected metered quantity of fluid.

A vacuum bottle with a rotary telescopic pressing head comprising a bottle body, wherein an inner container is disposed in the bottle body, a piston is disposed in the inner container, a pump sleeve is disposed on the inner container, and an eccentric hole is formed in the pump sleeve; a pressing pump is disposed in the eccentric hole, and a rotary sleeve is disposed on the pump sleeve; a rotary sleeve through-hole is formed in the rotary sleeve, and the pressing pump is located in the rotary sleeve through-hole; an inner pressing head is disposed on the pressing pump, and the inner pressing head can rotate horizontally; an outer pressing head is disposed on the inner pressing head; an inner cover is disposed on the rotary sleeve, and an outer cover is sleeved on the inner cover.

A full-plastic liquid pump includes a pump body, a pump head, a piston, a spring, a threaded cover, a one-way valve, and a suction pipe. Two ends of the pump head are respectively provided with a liquid outlet and a sliding pressing rod. The middle portion of the slidable pressing rod movably passes through a cover hole formed of the threaded cover. A piston is connected with the inner wall of the pump body to divide the inner space of the pump body into an air pressure cavity and a liquid storage cavity. A vent hole is formed in the upper portion of the pump body. An axial through hole is formed in the center of the piston. A lower end of the spring is fixed in the liquid storage cavity. The one-way valve is fixed in the liquid storage cavity corresponding to the suction pipe.

A pump dispenser has a pump body and a reciprocable plunger with a lock-down mechanism, including internal or external lock formations of the plunger and body, such as thread formations, by which the plunger can be locked down for shipping and released subsequently by a rotational release movement. To supplement security for demanding shipping conditions the dispenser also has a supplementary catch mechanism in which respective catch formations of the plunger and body engage selectively in the locked-down position to inhibit the rotational release movement. The catch formations may have circumferentially-directed surfaces which engage between the underside of a plunger head having a shroud and a nozzle and the top of the body beneath the plunger head. They can be released by resilient deformation of one or more of the catch formations.

A pumping device (100), comprising a movable part and a fixed part. The movable part is capable of reciprocating relative to the fixed part, thereby dispensing, by means of a straw (30) connected to the fixed part, a product contained in a container (20). The pumping device (100) comprises elastic members (150, 250, 350, 550, 650, 850, 950, 1050), one end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the movable part, and the other end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the container (20), or is supported on the container (20) by means of the fixed part. The pumping device (100) having the described structure allows the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) to be fabricated using plastic, and is also capable of obtaining the required elasticity.

A cartridge system for delivering an aqueous solution, which consists of a mixture of an active material with a liquid medium, including a bottle-shaped container, fastened to the neck of which there is a pump, where the container is fillable with the liquid medium, and the container includes a cartridge, an intake tube of a pump sealingly inserted in an upper side of the cartridge, wherein the active material is fillable into the cartridge through the intake tube, the cartridge is sealed from an exterior by at least one piston or stopper, the at least one piston or stopper being movably arranged in a wall of the cartridge and configured to enter into an interior of the cartridge under reduced pressure produced by the pump and opens to the exterior of the cartridge so that the active material is mixable with the liquid medium.

A food pump is provided with a safe outlet valve and an outer mounted spring. A pressing head, a primary column, a secondary column, a piston, a pump chamber, a spring and a bottle locking cover are also provided. A lock cover for fixing the primary column to the pump chamber is fixed on the pump chamber. An outer side of an upper end of the lock cover is provided with a cover flanging which is turned outwards and then turned downwards to stretch. An inner side of a locking flanging is provided with an inner thread in threaded fit with an outer thread of a lock opening of a lock cover, such that the primary column, the secondary column, the piston, the pump chamber, the spring, a glass bead and the lock cover can be stored and transported independently, thereby matching different pressing heads and bottle locking covers.

A push-type nozzle assembly includes a cylinder, a check valve, a plunger, a piston, a spring, a rotating member, a locking member, an upper push rod, a suction valve and a push head. When pushing the push head downward, and the outer chamber contact the locking member, the liquid in the cylinder is pushed out. When releasing the push head, the piston moves back by the spring to create a vacuum suction force to suck the liquid left in the nozzle back. When the outer chamber locks with the locking member, the bottom end of the piston rod seals the plunger to seal the cylinder so as to prevent leakage. When the outer chamber is separated from the locking member, the upper push rod seals the suction valve to avoid liquid from leakage. The inlet valve avoids the liquid from being accumulated in the cylinder and the top of the piston.
