Device for dispensing a fluid, comprising: a feed pipe, a dispensing pipe arranged in order to convey a fluid in a dispensing direction, a deformable pouch, a feed valve, which, in an open state, allows fluid to pass from the feed pipe to the inside of the pouch, and, in a closed state, does not allow this, and a dispensing valve, which, in an open state, allows fluid to pass from the inside of the pouch to the dispensing pipe, and, in a closed state, does not allow this, wherein the dispensing valve is held in the device by tightening between inner walls of the dispensing pipe.

A fluid dispenser including a body (6) receiving a dispenser member (3) connected to a reservoir (1) and to a fluid dispenser orifice (73), an actuator member (4) for actuating the dispenser member (3) and a module (5) comprising at least one source of radiation (51), such as a LED, the body (6) having a module housing (65) wherein the module (5) is received. The dispenser also includes a dispenser and diffuser head (7) mounted on the body (6) and forming an application wall (74) into which the fluid dispenser orifice (73) opens out for applying the fluid coming from the dispenser orifice (73) onto the skin. The module (5) is integral with the dispenser and diffuser head (7), thus forming together an integral unit (U) which is received on and within the body (6).

A dispenser has a body with a variable-volume storage chamber for storing product. A compression chamber is in fluid communication with the storage chamber for receiving substance therefrom. A one-way valve of the dispenser includes valve seat and flexible valve cover seated on the valve seat and defining a normally-closed seam therebetween forming a fluid-tight seal between the valve cover and valve seat. The flexible valve cover is movable relative to the valve seat to allow the passage of substance through the seam and out of the dispenser. A manually-engageable actuator connected to the dispensing portion is movable between first and second positions to dispense substance within the compression chamber out of the dispenser.

A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged from a nozzle portion by performing a discharge operation that presses the lid body to an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber by releasing the discharge operation. The dispenser includes a pressing support portion disposed to face away from a top surface of the lid body, and a discharge operation is performed by pinching a top portion of the lid body and the pressing support portion with fingers from lateral sides of the body.

A dispenser is disclosed that includes a pump having a pump chamber that receives a fluid, a pulsation dampener, and a discharge conduit. The pulsation dampener has a dampener housing with an interior volume and a dampener housing opening. A spring biased movable piston is located in the interior volume of the pulsation dampener and defines a variable volume headspace between the piston and the dampener housing opening. The discharge conduit provides fluid communication between each of an outlet of the pump chamber, the dampener housing opening, and a nozzle such that, when the pump is activated, at least a portion of fluid from the outlet of the pump chamber flows within the discharge conduit to the dampener housing opening. The dispenser is configured to, when the pump is activated, emit a substantially constant stream of fluid from the nozzle for at least one second.

A fluid filtration system for use in a lid of a fluid container, such as a water bottle or water jug, that is adapted to receive a quick disconnect fitting and a pressurization source. The quick disconnect fitting is connected to flexible tubing which can be used to withdraw fluid from the water bottle by using pressure as a motive force. A fluid filtration system for use in a lid of a fluid container, such as a water bottle, water jug, or barrel that comprises a lid configured to attach to a container. The filter is in fluid communication with the lid through an outlet port. An external pressure source pumps the fluid through the filter through an outlet valve on the outlet port of the lid.

A pen-type cosmetic dispenser for discharging a cosmetic medium, including an elongate housing extending in a main direction of extent, a discharge opening at an end face of the housing, a liquid reservoir arranged inside the housing, and a pumping device arranged inside the housing, which pumping device can be actuated by an actuating handle arranged on a lateral surface of the housing. The pumping device has a pump chamber, which is connected to the liquid reservoir on an inlet side and to the discharge opening on an outlet side. The pump chamber is delimited at least in sections by a wall which is flexible in shape, wherein the exterior surface of the wall forms the actuating handle.

Apparatuses and techniques are provided for dispensing fluid from a dispenser that includes a flexible membrane having different levels of pliability according to a voltage applied to the flexible membrane. According to some embodiments, a biasing device, such as a spring, is disposed on a first side of the flexible membrane and is configured to apply pressure to the flexible membrane. When a first voltage is applied to the flexible membrane, the flexible membrane becomes sufficiently pliable to enable the spring to flex the flexible membrane, pushing the flexible membrane into a pumping chamber disposed on the opposite side of the flexible membrane relative to the spring. The fluid is stored in the pumping chamber and the flexing of the flexible membrane causes the pumping chamber to compress. Such compression of the pumping chamber forces the pumping chamber to dispense the fluid through a pump outlet.

Provided is a cream-type cosmetic container, which can easily discharge a highly viscous content without a separate pumping member by allowing a button part to downwardly move and then return to an original location and thus changing the internal pressure of the container body when a user pressurizes the button part, and thus can save the assembling time and the manufacturing cost.

A fluid dispenser and applicator assembly having a reception body, a fluid applicator surface for coming into contact with a target, such as the skin; and a fluid dispenser having a reservoir, a pump, and a dispenser endpiece that defines an outlet surface and a fluid dispenser orifice. The dispenser is received in the reception body with its dispenser endpiece being received in a housing, its outlet surface forming a portion of the applicator surface, such that the dispenser orifice opens out directly in the applicator surface.
