A single-hand pressed foam pump head comprises a pump filled with foam liquid or emulsion. A spring is provided inside the pump. The pump comprises a press head and a fixed outflow cap; the fixed outflow cap is provided with a vertical connecting tube and is connected to a connecting end of a bottle; the connecting tube has a foam or liquid channel. A top portion of the connecting tube is provided with a horizontal connecting channel. The horizontal connecting channel is connected to a vertical plugged-in tube. When the connecting tube is pressed downward such that the vertical plugged-in tube is inserted into an outflow chamber of the fixed outflow cap, the connecting tube and the outflow chamber are connected to each other to form a top outflow channel. The present invention is simple in structure, stable in function and convenient for people to use.

A mist pump of a cosmetic container according to the present invention includes: a cap housing configured to be able to atomize contents by compressing external air introduced together with the contents in a cosmetic container and then discharging the contents in a whirlwind form by means of the compressed air; a piston housing; a compressing chamber formed between the cap housing and the piston housing; a piston formed to eject the compressed air and the contents while ascending; an opening and closing part that is formed between an inner surface of the piston housing and an outer surface of the piston, and through which the contents and the compressed air are ejected when the piston descends, and the external air is introduced into the compressing chamber when the piston ascends; and a pressurizing cap coupled to include an atomizing part that atomizes the contents by discharging the contents together with the compressed air in the whirlwind form through a nozzle passage formed in an upper end of the piston. Accordingly, the mist pump of the cosmetic container has the effects in that the mist pump may be used without being limited by the size of the cosmetic container, by virtue of external air compression, and a high level of stability can be achieved.

The present invention provides a foam dispensing unit (10) that dispenses a content liquid in a foamed state by causing the content liquid pumped out via a liquid flow channel (23) to pass through a porous member (29) provided in a foaming flow channel (24) together with air, the foam dispensing unit including a mechanism for variably positioning a passage surface (40), the mechanism rotatably holding the porous member (29) in the foaming flow channel (24) to variably position a content liquid passage surface of the porous member (29). The mechanism for variably positioning a passage surface (40) includes a loosely holding region (41) formed in the foaming flow channel (24) and the porous member (29) loosely mounted in the loosely holding region (41). The porous member (29) has a spherical shape, and freely rotates inside the loosely holding region (41) due to an action of a stream of the content liquid passing through the loosely holding region (41), so as to replace a surface thereof in a pass-through direction.

A hand cleaner foam dispenser with a first pump arrangement that discharges a first liquid and first air from the atmosphere through a first foam inducing member into a mixing chamber and a second pump arrangement that discharges a second liquid into the mixing chamber, and in which there is a simultaneous discharge of the first liquid, first air and the second liquid from the mixing chamber through an outlet foam inducing member to produce a foamed product delivered onto a person's hand. Preferably, the second pump arrangement may discharge not only the second liquid, but also second air drawn from the atmosphere and discharge the second liquid and the second air through a second foam inducing member into the mixing chamber.

A piston pump for dispensing fluid from a reservoir, an improved vacuum relief arrangement in which a passageway for flow of air from the atmosphere into the reservoir is provided at least in part through a piston-forming element of the piston pump.

A foam discharge container, including a container main body for accommodating a liquid composition and a foam discharge device which mixes the liquid composition with air and discharges it in a foam form. The foam discharge device has a plurality of porous bodies through which the liquid composition passes when the liquid composition is discharged, the plurality of porous bodies include a tip side porous body arranged in a vicinity of a discharge port of the foam discharge device, and the tip side porous body is composed of polyethylene terephthalate.

Various dispensing devices, such as foaming soap pumps, are disclosed. The soap pump can include a fluid storage unit and a fluid handling unit. The fluid storage unit can include a reservoir that is configured to hold a quantity of product, such as liquid soap. The fluid handling unit can include a pumping assembly and dispensing assembly. The soap pump can be configured to withdraw liquid soap from the reservoir, convert the liquid soap to foamed soap, and dispense the foamed soap from the discharge assembly.

A device, method and kit for replacing a conventional golf ball washing assembly that uses a crank lever, as well as its shaft (which fits into a base on the ground) to easily convert it to an eco-friendly item washing device is provided. The invention involves a hollow support tube and an associated head having a pump assembly releasably secured thereon. The entire conventional washer is removed, except for the base, and one end of the support tube is inserted into the base. The pump assembly is removed and a cleaning solution is poured through the head and into the support tube. The pump assembly is re-attached. A head nest receives a dirty golf ball therein. When placed in the nest, pump activation dispenses the cleaning solution directly onto the ball or other golf item, in a limited delivery of cleaning solution to the dirty item to reduce waste.

The invention relates to a device for dispensing a mist of an ophthalmic fluid, the device comprising a discharge opening for said mist, a mixing chamber communicating with a discharge opening, an air chamber, a first drive operable to expel air from the air chamber, a fluid chamber for holding a first volume of the liquid and communicating with the mixing chamber, a dosing chamber for containing a second volume of the liquid corresponding to a plurality of the doses, preferably to two doses, of the liquid, the dosing chamber communicating with or configured for communicating with a supply of the liquid, such as a collapsible liquid container or a liquid container having a movable bottom, and with the fluid chamber, a second drive operable to supply the second volume of the liquid from the supply to the dosing chamber and for emptying the dosing chamber by repetitive delivery of a single dose of the plurality of doses of the liquid contained therein to the fluid chamber, the air chamber communicating with the mixing chamber and/or with the fluid chamber for the expelled air to drive the liquid delivered to the fluid chamber into the mixing chamber by the expelled air.

A fluid dispenser includes a dispenser housing, a container for holding a foamable liquid, a foam pump, an outlet in fluid communication with the foam pump, and a vacuum actuated suck-back mechanism in fluid communication with the foam pump and the outlet. The foam pump has a liquid pump portion and an air pump portion. The vacuum actuated suck-back mechanism includes a chamber and a movable member. The chamber has a vacuum port that is in fluid communication with the air pump portion of the foam pump, and a suck-back port that is in fluid communication with the outlet. The movable member of the vacuum actuated suck-back mechanism moves under vacuum pressure to reduce the volume of the chamber. The volume of the chamber increases upon removal of the vacuum pressure.
