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 the air pressure in the rigid cartridge, wherein the rigid cartridge and the collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, and further wherein at least the rigid cartridge is disposable and can be made of a recyclable and/or biodegradable material.

A head (10) of a trigger dispenser device includes a bulb (70) having an elastically deformable casing (72) that includes a vent lip (90), molded in one piece. With the casing (72), the vent lip (90) forms a venting valve.

A portable chargeable spray bottle is disclosed comprising a body comprising an upper part and a lower part; a spray nozzle assembly equipped on the upper part, and a liquid charging structure placed at the bottom part. It is further comprises an exhaust structure comprising an exhaust hole penetrating the body, whereby exhaust air flow can escape via the exhaust hole to outside the bottle.

A foam dispenser has a pump body and a sprung plunger (2). A one-piece moulded cylinder component (31) comprises a larger diameter portion (32) for an air cylinder and a smaller diameter portion (33) for a liquid cylinder. The plunger (2) carries respective pistons (22,21) movable in the air cylinder and liquid cylinder to pump air and liquid through valved outlets to a mixing chamber (8) in the plunger for foam production. The liquid cylinder has a discrete inlet piece (9) including an inlet valve. The liquid outlet valve is operated by a valve pin (25) connected to a valve pin retainer (39) which is formed integrally as a one-piece moulding with the cylinder component (31).

A reservoir for a fluid product having a container defining a neck and a mounting part mounted on the neck, the mounting part forming a basket arranged at the neck and a plunger tube, which extends from the basket into the container, the plunger tube being initially sealed by a sealing member. The reservoir further has an insert located in the basket and having a piercing element capable of moving between an initial position, in which the sealing member forms a seal, and a final position, in which the sealing member is displaced by the piercing element to an open state.

A dispenser member, such as a pump or a valve, including a body defining an inlet tube and in which a valve rod is axially movable back and forth, the body being provided with a vent lip that extends around the body, pointing outwards and downwards towards the inlet tube, thereby defining an outer edge that is not in contact with the body, the vent lip being formed by a sleeve that is engaged axially around the body to form a seal between them, the sleeve forming a leaktight sheath that is engaged in leaktight manner around the inlet tube of the body; the dispenser member being characterized in that the vent lip is situated axially above the sealing sheath.

Exemplary embodiments of dispensers and refill units are disclosed herein. An exemplary refill unit for a soap, sanitizer or lotion includes a non-collapsing container. The non-collapsing container includes a neck. An annular projection is located at least partially on the neck. A one-way valve is located proximate the annular projection. The one-way valve allows air to flow into the non-collapsing container once the vacuum pressure in the container reaches the cracking pressure of the one-way valve and the one-way valve prevents liquid from flowing out of the annular projection. In addition, a pump for pumping the contents of the container out of the container is also included.

The invention provides a dispensing assembly to dispense a foam, comprising: a double cylinder element (2) mounted or to be mounted in an opening of a container (100), comprising a liquid cylinder (3) and an air cylinder (4), wherein the liquid cylinder has a smaller diameter than the air cylinder, and wherein the liquid cylinder and the air cylinder are arranged substantially concentrically, and a piston assembly (10) comprising a liquid piston (11) and an air piston (12) for reciprocal movements in the liquid cylinder and air cylinder, respectively, and a common operating part for operating the liquid piston and air piston, wherein a liquid pump chamber (14) is at least delimited by the liquid cylinder and the liquid piston, said liquid pump chamber having a liquid inlet (15) and a liquid outlet (16), wherein an air pump chamber (25) is at least delimited by the air cylinder, the air piston and the liquid piston, said air pump chamber having an air inlet (26) and an air outlet (27), wherein the piston assembly (10) further comprises a dispensing channel (28) in fluid communication with the liquid outlet and the air outlet, wherein the dispensing channel ends in a dispensing opening (29), characterized in that the air outlet (27) is provided in the liquid piston in a region of the air pump chamber opposite to the air piston (12).

A foam generator for compression receptacles is configured such that liquid contents pumped by an internal pressure as a result of directly compressing a 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. Accordingly, the foam generator not only is capable of preventing the corruption of the liquid contents, which are not in contact with any separate metal member, but also further improves product responsiveness, since the contents are instantly discharged in the form of foam by compressing the compression receptacle.

A motor system includes at least two motors respectively having an output power and a rotary shaft, wherein at least one coupling is provided to connected the at least two rotary shafts. A detect unit is electrically connected to each of the at least two motors and detects the currents of the at least two motors and forms detecting signals relative to the current value of each of the at least two motors. A control unit is electrically connected to the at least two motors for receiving a controlling signal and the detecting signal for adjusting an output power to the electric actuator.
