A hand pump fabricated entirely from plastic components for dispensing liquids, is provided. The hand pump includes an actuator, a closure, a housing having a lower check valve, and a piston having an integrated upper check valve in the form of an inverted cone suspended within a cylinder. An elastic, dome shaped, plastic return spring is utilized to return the actuator to its rest position after actuation. Used pumps do not require disassembly to be recycled.

A standalone pedal sprayer is an apparatus that dispenses a solution. The apparatus serves as a free-standing dispenser that facilitates the retrieval of a solution such as hand sanitizer, alcohol, and the like. The apparatus includes a sprayer housing, a foot pump, a supply tubing, and a nozzle. The sprayer housing is vertically oriented and positions the nozzle within hands-reach of a user. The sprayer housing also serves as a reservoir for a solution and is refillable. The foot pump dispenses the solution within the sprayer housing and out of the nozzle. The apparatus further includes a pedal shield that protects a rubber cap of the foot pump from being damaged. In order to provide access into the sprayer housing for refill, the sprayer housing further includes a refill cover and a cam lock. The cam lock prevents any unauthorized solutions or materials from entering into the sprayer housing.

A backpack sprayer includes a housing, a spray nozzle assembly, a fan assembly and a switch assembly. The housing is configured to contain a liquid. The spray nozzle assembly is communicated with the housing, and is configured to spray the liquid out from the housing. The fan assembly is connected to the spray nozzle assembly, and is configured to provide the spray nozzle assembly with power to spray the liquid out from the housing. The switch assembly is connected to the spray nozzle assembly and electrically connected to the fan assembly, and is configured to control opening and closing of the spray nozzle assembly and start and shutdown of the fan assembly simultaneously.

Provided is a cosmetic container having a retractable button including: a container body filled with contents; a pump part arranged on the upper portion of the container body in order to discharge the contents externally through a pumping action; and a button part arranged on the upper portion of the pump part to make the pumping action carried out by the user's pressing and releasing action, the button part having a discharge part to discharge the contents externally, wherein the button part has an inhalation space formed inside the button part, and the inhalation space is communicated with the discharge part, is increased or decreased in volume according to pressurization and release of the button part in order to inhale the contents remaining in the discharge part.

Exemplary foam-at-a-distance systems include a spout, a container, and a foam generator having a suck-back mechanism located within the spout. The system includes a liquid pump chamber, an air pump chamber, a liquid conduit and an air conduit. The foam generator has a differential bore housing. The differential bore housing has a first portion with a first inside bore and a second portion with a second inside bore, wherein the first inside bore has a smaller diameter than the second inside bore. A piston having a seal extending from the piston that is in contact with the second inside bore is also included. A mixing chamber is located in the large bore. Movement of the seal in an upstream direction provides negative pressure in the second mixing chamber and draws in fluid from the outlet.

A pump container includes: a container in which a liquid is contained; a shoulder member configured as a cylindrical member, the upper and lower portions of which are open, the shoulder member having a lower outer peripheral portion formed to have an inner diameter larger than that of an upper inner peripheral portion; a valve housing comprising a cylinder portion, a hose being inserted/connected into/to the lower portion of the cylinder portion, the upper portion of the cylinder portion being open, the valve housing comprising an outer-periphery cylinder portion configured on the outer peripheral edge of the cylinder portion in a flared shape, the upper portion of the outer-periphery cylinder portion being open, the valve housing comprising an upper-end insertion portion bent outwards, and the valve housing comprising a seating portion bent outwards from the upper end of the upper-end insertion portion and a discharge cap.

A fluid transfer assembly comprises a housing for accommodating a fluid. A bellows member disposed in the housing defines an opening therethrough adapted to be in fluid communication with an applicator assembly. The bellows member is adapted to operatively engage the applicator assembly for extension in a first direction and contraction in a second direction. The bellows member seals against the inner surface of the housing during extension and contraction for defining a variable volume chamber with the housing. Expansion of the bellows member in the first direction reduces the chamber volume for generating positive pressure in the housing and forcing fluid through a valve to the applicator assembly. Contraction of the bellows member in the second direction increases the chamber volume for generating negative pressure within the housing for drawing fluid into the chamber.

A container for spraying liquid is disclosed, which includes: a tube having a filling space; a body in which the tube is inserted, where the outer perimeter of the tube and the inner perimeter of the body form a body outlet passage, a lower tube hole is formed at a bottom of the tube as an entrance to the body outlet passage, and an upper movement hole is formed at a top of the body as an exit from the body outlet passage; a body cover coupled to the top of the body, where the body cover includes a cover channel connecting with the upper movement hole and a pump insertion space connecting with the cover channel and receiving a pump inserted therein; and a pump support coupled to the top of the body cover and supporting the pump to block outside air from entering the pump insertion space.

A cosmetic vessel may include a vessel body including an inner case configured to accommodate cosmetics and having an inlet, and an outer case configured to accommodate the inner case therein and having an opening in a top thereof, a cap part coupled to the open top of the outer case, a discharge means coupled to the inlet and configured to discharge the cosmetics to an outside through a suction pipe extending to a bottom surface of the inner case, and a discharge part moving downwards to operate the discharge means and configured to transmit the cosmetics discharged from the discharge means to the outside.
