An oral care implement including a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir, in the body, for storing an oral care fluid; and a pump for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises a first check valve downstream of the reservoir, and a second check valve downstream of the first check valve and upstream of the fluid outlet. One of the first and second check valves comprises a valve seat defining an opening through which the oral care fluid is flowable, a valve member separate from the valve seat and comprising a stopper movable linearly relative to the valve seat, and a resilient element separate from the valve member and biasing the stopper towards the valve seat.

A pump for dispensing a fluid product, able to be mounted on a container of the flexible tube or rigid flask type, includes a variable-volume metering chamber at least partly defined by a membrane deformable between an initial state in which the volume of the metering chamber is maximum and a deformed state in which the volume of the metering chamber is minimum. The pump also includes a valve for admitting the fluid product to the metering chamber. The pump further includes a valve for discharging the fluid product from the metering chamber. Finally, the pump includes means for opening and closing the admission and discharge valves. Notably, the pump consists of a single molded piece.

A fluid dispensing device having a flexible fluid pouch and a dispensing assembly, the dispensing assembly having a top piece and a bottom piece, the top piece having a flexible actuator including a flexible dome and a flexible flange extension, the bottom piece having a bottom portion of a pump chamber, a pump chamber inlet, a chamber inlet valve, and a bottom portion of an outlet valve, the top piece and the bottom piece mated together to form a pump chamber and an outlet valve, the device configured to allow bidirectional fluid flow through either or both inlet and outlet valves, and to dispense a volume of fluid that is less than the volume of the pump chamber. The flexible pouch may have a single opening or two openings. In the case of a single opening, the entire dispensing assembly is in the interior of the pouch. In the case of two openings, only the flexible dome extends to the exterior of the pouch. The outlet valve is configured so that the more pressure that is applied to the flexible fluid pouch, the more tightly the outlet valve seals.

A dispenser pump is constituted by a closure body (2), a diaphragm body (3) which forms a pump chamber with the closure body and optionally a top actuator (4) for pressing the diaphragm body (4). The diaphragm body has a deformable wall (35) formed integrally in the same polymer as its annular mounting portion (31). An inlet valve (5) through the floor (21) of the closure body has a flap (52) which is formed and hinged integrally with that floor (21). An outlet valve may also be formed in the same polymer, either integrally with the diaphragm body or as a separate component. The deformable wall of the diaphragm body is shaped to generate a restoring force itself without a separate spring, so that the entire pump may be made from the same polymer e.g. polypropylene and without metal components.

Method and apparatus are disclosed for methods and apparatus for application of washer fluid to vehicle cameras. An example vehicle includes a camera including a lens. The example vehicle includes a reservoir and a flexible housing defining a cavity fluidly coupled to the reservoir and including an outlet valve adjacent the lens. The example vehicle also includes a solenoid coupled to the flexible housing to affect a cavity pressure by flexing the flexible housing. The outlet valve opens upon the cavity pressure being greater than a predetermined threshold to spray the washer fluid onto the lens.

A dispensing head including:a cap having: an outer wall with at least one part referred to as the shell part and at least one part referred to as the pressing part that is made of a material more flexible than the at least one shell part; at least one outlet; an insertion orifice,a stopper, the stopper being mounted in the cap by being inserted into the cap from the insertion orifice side and in an insertion direction, at least one assembly, each assembly comprising: an inlet, passing through the stopper; a deformable pocket, an interior volume of which is intended to contain the fluid of this assembly and is delimited at least in part by the at least one pressing part of the cap; preferably a feed duct and/or a dispensing duct.

A pump includes a housing forming a chamber; a dispensing opening; and a regulator fixedly arranged in the chamber. The regulator includes an inner valve for regulating a flow of liquid between the container and the chamber; an outer valve for regulating a flow of liquid between the chamber and the dispensing opening; a stem resilient along its length, sideways bendable, and extending in a longitudinal direction of the housing between the inner valve and the outer valve; and a displacement guide located at an outer portion of the stem on an inner side of the outer valve. An outer perimeter of the displacement guide and a portion of an internal surface of a guide region located adjacent the displacement guide are adapted to transfer the sideways bending of the stem to a relative displacement between the outer valve and the housing along the longitudinal direction of the housing.

A dispenser has a body with a variable-volume storage chamber for storing substance, and a dispensing portion defining a dosage chamber in fluid communication with the storage chamber. A first valve includes a valve seat and a flexible valve cover seated thereon defining a normally-closed fluid-tight seam therebetween. The valve cover relative to moves from the valve seat to allow substance through the seam and out of the dispenser. A second valve allows substance from the storage chamber into the dosage chamber and substantially prevents flow from the dosage chamber into the storage chamber. An actuator is manually movable between (i) a first non-actuated position, and (ii) a second actuated position extending into the dosage chamber for compressing a dose of substance therein, dispensing substance through the first valve. The elasticity of the actuator causes it to return to the first non-actuated position upon manually releasing the actuator.

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

The disclosure relates to systems and methods for metering a dose volume of fluid that may be used to treat microelectronic substrates. The system enables precision dispensing of relatively small amounts of a liquid chemical into a chemical bath or processing chamber for microelectronic substrates. The dispensing device may include a fluid conduit with a plurality of actuation devices that may limit fluid communication between the actuation devices and store a portion of the fluid in expandable membrane. The actuation devices may push or pull the fluid within the fluid conduit when the expandable membrane expands or contracts. The configuration and operation of the actuation devices may enable the collection, isolation, and dispensing of the dose volume.
