The present invention provides means and methods for delivering a predetermined volume of a substance, within at least one body cavity of a subject, comprising a predefined volume for containing the predetermined volume of the at least one substance; a delivery end for placement in proximity to the body cavity; the delivery end comprises at least one orifice of diameter D [mm]; a valve mechanically connectable to the container, characterized by at least two configurations: (i) an ACTIVE CONFIGURATION in which the valve enables delivery of predetermined volume V.sub.sub [ml] of the substance; and, (ii) an INACTIVE CONFIGURATION, in which the valve prevents delivery of the predetermined volume V.sub.sub [ml] of the substance from the container to the body cavity; and a fluid tight chamber configured to contain predetermined volume V.sub.gas [ml] of pressurized gas at a predetermined pressure, P.sub.gas [barg].

A foam generator is configured such that liquid contents pumped by an internal pressure as a result of directly compressing an inverted compression receptacle, having the liquid contents stored therein, are mixed with air in a gas-liquid mixing chamber and, at the same time, directly discharged in the form of foam. That is, direct compression of the inverted compression receptacle allows the liquid contents to be instantly discharged in the form of foam, thereby further improving product responsiveness.

An organic liquid soap composition; and a foam producing soap product comprising: a) a foamable organic liquid soap composition comprising the anti-microbial active ingredients of: organic shea butter; organic spearmint oil; USDA approved lime oil; organic thyme oil; and organic rosemary extract; and, b) a foam soap dispenser for dispensing the organic liquid soap composition as a premeasured amount of foaming soap, wherein the foam dispenser comprises: a recyclable plastic; a bottom front tab comprising a green color and a label indicating the composition is an organic soap. The organic soap composition may further comprise: glycerin; saponified organic coconut oil; organic olive oil; organic sunflower oil; organic jojoba oil; and organic aloe vera. And the organic soap composition has a shelf-life of about three years, and able to eradicate about 74.6% through 77.6% of the bacterial strain Staphylococcus aureus after at least one minute of direct contact with the composition.

A foamer dispenser including a mesh filter that is disposed in a mixture flow path of a jet ring to allow a mixture to pass is provided. A connecting flow path area between a liquid flow path and the mixture flow path and a connecting flow path area between an ambient air flow path and the mixture flow path have the relation 2.8S.sub.1/S.sub.23.8, and/or, a smallest flow path area of the mixture flow path is located on an immediately upstream side of the mesh filter, and the smallest flow path area and a flow path area of the mesh filter have the relation 4S.sub.4/S.sub.310.3.

Exemplary embodiments of pumps, refill units and dispenser systems are disclosed herein. An exemplary refill unit for a soap, sanitizer or lotion includes a container for holding a fluid and a pump secured to the container. The pump includes a housing, a liquid piston, a liquid pump chamber, an air piston, an air pump chamber; and a piston holder. The liquid piston is connected to the air piston. The piston holder is connected to one of the liquid piston and the air piston. The connection comprises one or more projections and one or more grooves. The volume of the liquid pump chamber and the air pump chamber both change as a function of the engagement of the one or more projections with the one or more grooves.

A soap dispenser including a rigid cartridge, an inverted dispensing pump, a collar carrying a lever for actuating the pump, and a venting system for equalizing air pressure in the rigid cartridge. The rigid cartridge and collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, in which at least the rigid cartridge is disposable being made of recyclable and/or biodegradable material.

The invention concerns a device (10) for dispensing a mixture (S) constituted by a first fluid (F1) and a second fluid (F2), suited to be applied to a container (C). The device comprises: an outlet duct (20) for the mixture (S); a reception and/or transit chamber (43); means (50, 60) for generating the mixture (S); first valve means comprising a first movable element (32); second valve means comprising a second movable element (32); third valve means comprising a third movable element (31a, 31b). Two among the first movable element (32), the second movable element (32) and the third movable element (31a, 31b) belong to a single valve element (30; 130). The invention concerns also a system for dispensing a mixture (S) constituted by a first fluid (F1) and a second fluid (F2) comprising a container (C) and a device (10) as described above.

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 dispensing system includes an above-deck nozzle portion, a reservoir for holding fluid, a foam pump, a multi-lumen dispense passage, and a mixing portion. The above-deck nozzle portion has a dispenser outlet and is disposed above a counter. The foam pump is disposed below the counter and includes at least one liquid pump chamber in fluid communication with the reservoir, at least one air pump chamber, and a pump outlet. The multi-lumen dispense passage includes an inlet, an outlet, at least one liquid lumen, and at least two air lumens. The inlet is in fluid communication with the pump outlet, the outlet is in fluid communication with the dispenser outlet, and the at least one liquid lumen and the at least two air lumens are each in fluid communication with the inlet and the outlet of the multi-lumen dispense passage. The mixing portion is disposed between the multi-lumen dispense passage and the dispenser outlet.

A fluid dispenser includes a housing, a pump, an outlet nozzle, a reservoir, a liquid passage, an air passage, and a refill container. The pump and reservoir are attached to the housing, and both the outlet nozzle and the reservoir are in fluid communication with the pump. The reservoir has at least one engagement member, and the liquid passage and the air passage are located in the engagement member. The refill container has at least one sealing member, and the refill container is configured to be releasably attached to the reservoir such that the refill container is in fluid communication with the reservoir. When the refill container is attached to the reservoir, the engagement member engages the sealing member to cause the liquid passage and the air passage to be in fluid communication with the refill container.
