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 misting device has a form factor that allows the device to be handheld. The device includes a fluid tank that can be pressurized to force the contained fluid under pressure through a fluid delivery system. A hand-operated pump injects air into the fluid tank to pressurize the fluid tank. The pump includes a pump handle located at the bottom of the tank at one end of a rod, and a piston at the other end of the rod. A pressure-relieving air channel extends through the piston, the rod, and the pump handle to emit air out of the pump and into the environment when the fluid tank is at a maximum pressure. A pressure relief valve is disposed inside the piston to control the flow of air through the air channel. The pump handle locks against the tank using a twist-and-lock mechanism to remain secured in a retracted position.

The present invention relates to a portable hydrogen water mist sprayer comprising a water container which has an open-top coupling part protruding from the top center, a central case, the bottom of which becomes coupled to the top of the water container, and a top cap that becomes coupled to the top of the central case, and wherein an enclosed installation frame placed in the bottom of the central case and the bottom of the central case, which becomes coupled and fixed to the bottom of the central case, are coupled to the open-top coupling part of the water container for airtightness, and an airtightness frame that has a discharge guide groove and a discharge guide hole to selectively release the gas from hydrogen water production inside the water container is applied so that, in case the internal pressure of the water container exceeds a certain level, the gas from inside the water container can flow through the enclosed installation frame and airtightness frame and be discharged outside via the discharge guide groove and discharge guide hole. Accordingly, in case the internal pressure of the water container exceeds a certain level, infiltration of gas containing hydrogen components and/or water molecules into the electrical components involved in hydrogen production, such as the control unit, can be prevented, and the gas is discharged outside so as to substantially improve the safety and durability of the mist spraying device.

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.

The present disclosure is directed to a holder. The holder includes a main body, the main body including an interior surface and an exterior surface, a film that extends around at least a portion of the circumference of a first end of the main body and covers an opening of the first end of the main body, and a sheet including a first surface and a second surface, the second surface opposed to the first surface, the first surface operably attached to the seal at at least one point, the sheet configured to extend a distance along an interior of the main body from the first end towards a second end, wherein at least a portion of the first surface of the sheet contacts the interior surface of the main body, and wherein a liquid composition contacts a second surface of the sheet.

A two-component piston for a cartridge includes a piston cover and a piston body. The piston cover has a radially extending attachment portion, a rear side and a front side. The piston body includes a front side and a rear side. The rear side of the piston cover is arranged adjacent to at least a part of the front side of the piston body and includes a valve member configured and arranged to be received within the piston body and to extend into the piston body towards the rear side of the piston body. The piston cover moves relative to the piston body upon actuation of the valve member, and the piston cover is non-releasably connected to the piston body by a part of the piston body being overmolded to the radially extending portion of the attachment portion of the piston cover.

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).

The present disclosure is directed to a tubular holder. The tubular holder includes a tubular main body, the tubular main body including an interior surface and an exterior surface, a film that extends around at least a portion of the circumference of a first end of the tubular main body and covers an opening of the first end of the tubular main body, and a sheet including a first surface and a second surface, the second surface opposed to the first surface, the first surface operably attached to the seal at at least one point, the sheet configured to extend a distance along an interior of the tubular main body from the first end towards a second end, wherein at least a portion of the first surface of the sheet contacts the interior surface of the tubular main body, and wherein a liquid composition contacts a second surface of the sheet.

An injection device able to evacuate air bubbles trapped with injectable liquid includes a needle tube, a push rod slidable installed in the needle tube and a piston secured on one end of the push rod.
