A trigger-type liquid dispenser, in which an upright and inverted dual unit includes a joint member, a pipe holding member, and a valve body. The joint member includes a through hole, which may be closed by the valve body, a valve-body-holding wall portion, which accommodates the valve body above the through hole in a manner such that the valve body is displaceable upward and downward, and an opening portion, which is formed in the valve-body-holding wall portion. In the inverted position, the upright and inverted dual unit permits content liquid contained in a container to be supplied to the dispenser main body by passing content liquid through a flow path from opening portion, through the hole, to the flow path defined between the joint member and pipe holding member sequentially. The valve body is inserted through the opening portion to be accommodated in the valve-body-holding wall portion.

A pump for connecting the inside and the outside of a product vessel for pharmaceutical use including an upstream end for passing a product intended for extending into the vessel and for being in fluid communication with the vessel and, downstream from the upstream end, a check valve switching between configurations for sealing and passing a product. The upstream end is extended upstream by a member forming a passage of a product in a labyrinth, referred to as labyrinth-forming member.

An applied liquid applicator for discharging applied liquid by turning of an operating portion provided to a barrel main body achieves improved filling efficiency of the applied liquid stored in the barrel main body with respect to an inside capacity of the barrel main body. The applied liquid is fed to the applicator portion through the first valve and the applied liquid feed path by turning the operating portion and sliding the piston in the front-back direction by use of the cam mechanism portion.

A manual pump (P) having a pump body (B) defining a slide cylinder (F) for a piston (K) secured to an actuator rod (S); a pump chamber (C) and an outlet valve (V) arranged between the pump chamber (C) and a dispenser orifice (O) so as to dispense the fluid from the pump chamber (C). The pump includes an inlet valve (2, 12) arranged between the pump chamber (C) and an inlet (I) of the pump (P) to take the fluid into the pump chamber (C) from the reservoir (R), the inlet valve having a movable member (2) that selectively bears against a valve seat (12), a return passage (23) enabling a fraction of the fluid that is put under pressure in the pump chamber (C) to escape therefrom without passing via the outlet valve (V). The return passage (23) creates a lack of sealing at the inlet valve.

The present invention relates to a dispensing pump which mainly comprises a cap, a cylindrical pump body having a first elastic member therein, a ball valve fixed at a bottom of the cylindrical pump body, a needle valve fixed at a top end of the cylindrical pump body, and a pressing tube connected to an upper side of the needle valve and having a pressing head connected to an upper end thereof.

A trigger-type liquid ejector includes: an ejector main body; and nozzle member provided with an ejection hole. The ejector main body includes: a vertical supply pipe for sucking-up liquid; an ejection barrel communicating with the inside of the vertical supply pipe; and a trigger mechanism including a trigger, the trigger being arranged to be movable rearward in state of receiving forward force, and the trigger mechanism being lead liquid from the vertical supply pipe into the ejection barrel in accordance with rearward movement of the trigger and to eject the liquid from the ejection barrel. The nozzle member is provided with: a cylinder communicating with the inside of the ejection barrel through a supply hole; a plunger accommodated in the cylinder to be movable rearward in a state of receiving forward force; and a communication hole allowing the inside of the cylinder and ejection hole to communicate with each other.

A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

A system for dispensing a fluid, such as a hand soap or the like. The system includes a dispenser and/or a refill cartridge. The dispenser includes a dispenser body having a refill cavity, a dispenser lid configured to be coupled to the dispenser body, and a pump sub-system mounted to the dispenser lid. The pump sub-system includes a first dip tube, a dispensing orifice, and a pump. The refill cartridge includes a cartridge body having a fluid cavity, a store of a fluid in the fluid cavity, and a second dip tube extending into the store of the fluid. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The dispenser lid may be coupled to the dispenser body thereby mating the first and second dip tubes to enable dispensing of the fluid.

A water resistant hand pump fabricated entirely from plastic components is provided. The pump comprises a pump housing, actuator, piston, chaplet, stem and a pump spring where the pump spring is in the form of an elastic dome made from an elastomeric polymer. The all plastic hand pump is suitable for dispensing liquids and creams from a dispenser bottle. Used pumps do not require disassembly to be recycled.
