A liquid pump capable of achieving pressure equilibrium includes a body, piston member, unidirectional input valve, unidirectional output valve, input inner-pipe, unidirectional gas-feeding hermetic-seal valve and input outer-pipe. The body has an input opening, output opening and piston opening. The piston member has a piston space communicating with the piston opening. The unidirectional input valve includes an input plug and input resilient element. The input plug abuts against the input opening. The unidirectional output valve includes an output plug and output resilient element. The output plug abuts against the output opening from outside. An input channel of the input inner-pipe communicates with the input opening. Direction of gas-flow between the unidirectional gas-feeding hermetic-seal valve and the input inner-pipe is opposite input direction of the input channel. The input outer-pipe has an input portion communicating with the input channel. A gas-feeding-channel is defined between a gas-feeding-portion and the input inner-pipe.

Liquid product pump devices, systems, and methods of using the same. An exemplary system of the present disclosure comprises a device, comprising a pump mechanism coupled to a receiving tube whereby a distal end of the receiving tube extends into a skirt, wherein when the skirt is attached to a neck of an bottle having liquid contents therein and wherein when the device rests within or upon a pump base, pressing the inverted bottle and the pump base toward one another causes a portion of the liquid contents to transfer from the inverted bottle and out of the pump base, and further comprises the bottle and the pump base.

A press pump (1) comprises a press pump body 10) in which a spring tube (20) is provided, a spring (21) is contained within the spring tube (20); a cylinder head (30) mounted on the press pump body 10) and including a internal bore (31); a press head (40) including a pressing portion (41) and a rod portion (42), the rod portion (42) is fit within the internal bore (31) of the cylinder head (30), and a lower portion of the rod (42) engages with the spring (21), so that the spring (21) applies an upward bias force on the press head (40); and a piston (50) connected to the press head (40) and is slidably and sealingly engaged with the internal circumference of the press pump body 10). The press pump (1) can use a spring (21) with relatively small size, while meet the requirement of large displacement, thus reducing manufacturing cost, and also can prevent contact between the product and the spring (21), avoiding negative effects between them.

Dispenser systems, dispensers, and repositories can add a fragrance to an unscented liquid beauty preparation. The dispenser system includes a dispenser having a cavity for retaining at least a first liquid, and a repository configured for removably attaching to the dispenser, the repository having a reservoir for retaining at least a second liquid. The dispenser is coupled with a pump assembly including at least one pump for drawing the at least a first liquid and the at least a second liquid into a mixing chamber. The mixing chamber is coupled with an actuator in such a manner that when the actuator is pressed down by an external force, the mixing chamber communicates with the pump to suction the first and second liquids into the mixing chamber to form a liquid mixture for dispensing through a nozzle.
