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 foam dispensing container (100) has a container body (40) that reserves a liquid agent (L); a head part (30) that has an outlet (20), and dispenses the liquid agent (L) delivered from the container body (40) through the outlet (20) into foam; and a pump head part (32) that allows dispensing of a predetermined amount of the foamy liquid agent (foam) through the outlet (20) each time it accepts a user's operation. The outlet (20) is formed with a contiguous geometry narrowed from an intended shape. A foam, dispensed through the outlet (20) as a result of a single or multiple operations of the pump head part (32), is built up into the intended shape in a plan view seen in the dispensing direction.

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.

The sprayer includes a sprayer housing defining a chamber, and a cylinder within the chamber. The cylinder defines more than one discharge tube positioned in a longitudinal direction within the sprayer housing, the cylinder being selectively rotatable within the chamber. More than one suction tube extends from a lower portion of the sprayer housing. The more than one suction tube is in selective fluid communication with the more than one discharge tube of the cylinder, as the cylinder is rotated within the chamber. The foam sprayer attachment includes a major body defining a discharge channel and a screen traversing the discharge channel. The major body includes a base with a connecting structure that is a raised lip or a cut-out area that conforms the base to a raised ridge on a discharge connection of the sprayer. The connecting structure includes a pair of non-raised lips bracketing each connecting structure.

A trigger-type liquid ejector which includes an ejector main body and a nozzle member in which an ejection hole is formed, the ejector main body including a vertical supply tubular pipe, an injection tubular portion, and a trigger mechanism, the nozzle member including a nozzle main body and a valve body, the nozzle main body including a valve seat portion having a valve seat plate, an inside of the valve seat plate communicating with the ejection hole, the nozzle main body including a tubular foam-forming portion positioned in a front of the ejection hole and configured to surround the ejection hole, and the foam-forming portion is provided with an outside air introduction hole penetrating through the foam-forming portion in a radial direction thereof.

An all-plastic external foam pump, including an actuator, a fixing member, a plunger, an elastic member, a cylinder body, and a straw, is provided. One end of the fixing member is fixed or detachably connected to the actuator, and the other end is fixed or detachably connected to the plunger. The fixing member is at least partially accommodated in the cylinder body. One end of the plunger is penetrated into the elastic member. The straw is installed on one end of the cylinder body. A pulling rod is disposed in the plunger. The pulling rod is disposed in linkage with the plunger. The elastic member is made of a recyclable elastic material. A liquid mixing portion is disposed in the fixing member.

An exemplary refill unit for a foam dispenser includes a container for holding foamable liquid and a liquid pump. The liquid pump includes a pump housing and an outlet nozzle with an elongated central axis. The pump housing has an arcuate shaped liquid pump chamber formed by a backing plate. The backing plate includes a liquid inlet and a flexible membrane. At least a portion of the elongated central axis of the nozzle extends through a central area defined, at least in part, by the arcuate shaped pump chamber.

A foam dispenser has a foam-generating pump (1) mounted on a container (100) to hold liquid. The pump (1) has a liquid intake conduit with a ball valve (27) and an air intake conduit (45) provided partly by a jacket component (4) fitting around the pump body (2) with clearance. The pump has structure defining a mixing zone (50) for mixing air and liquid, a foam chamber (28) for holding foam received from the mixing zone, and a discharge conduit leading from, the foam chamber to a discharge outlet (36). The mixed air and liquid pass through a permeable foam, regulator mesh (54), One or more air inlets (47) lead into the mixing zone (50) from the air intake conduit (45). A liquid inlet in the form of a restricted jet orifice (89) leads into the mixing zone (50) from the liquid intake conduit, upstream of the inlet ball valve (27). A regulator mesh (53) is also provided between the liquid inlet and mixing zone.

The present invention relates to a foam dispensing apparatus including a nozzle portion that mixes a liquid with gas so as to dispense the liquid in a form of a foam. The nozzle portion includes: a foam generation mechanism including a gas liquid mixing portion in which the liquid and the gas are mixed and a first porous body that is disposed downstream of the gas liquid mixing portion; a cavity that is located below the first porous body and whose cross-sectional area defined by a plane perpendicular to a foam dispensing direction T is larger than the area of the first porous body; and a foam dispensing outlet that dispenses foam that has passed through the cavity to an outside. The foam dispensing outlet is configured so as to form shaped foam having a predetermined shape, and an opening area of the foam dispensing outlet that is on the cavity side is smaller than the cross-sectional area of the cavity.

Provided is a trigger-type liquid dispenser (1) including an operating lever (6) held swingably by a main body portion (3) in which a pump is disposed and including a spring member (7) that imparts restoring force to the operating lever (6). The trigger-type liquid dispenser (1) is configured to draw, pressurize, and force-feed a content liquid contained in a container (C) to dispense the content liquid through a nozzle (5), by actuating the pump in response to the operating lever (6) being pulled repeatedly. The spring member (7) is held swingably with respect to the main body portion (3), and, in response to the operating lever (6) being pulled, the spring member (7) undergoes elastic deformation and swings with respect to the main body portion (3).
