Abstract:
A pump assembly with a first pump to displace a first volume and a second pump to displace a second volume greater than the first volume. The first pump draws liquid from a reservoir and dispenses it to the second pump. The second pump draws in the discharge from the first pump and an additional volume of air such that the second pump discharges both liquid and air. The first pump preferably has a piston movable in a first inner chamber and the second pump has the same piston movable in a second outer chamber. The first and second chambers communicate together. In one version, a one-way valve provides flow outwardly only from the first chamber to the second chamber and the first pump discharges while the second pump draws in, and vice versa.
Abstract:
A cosmetics discharge structure of cosmetics case including a receiving part 11, an inner space part 24a formed to a cone type elastic part 24 through a opening hole 28, a vertical rod 27, an inner hole 22, and an inner space part 24a discharges to a brush 43 through a liquid discharger 42 from the inner hole 22. An inner moving body 10 declines and returns by an expansion of a cone type elastic part 24 formed to the middle member 20 and elastic and repellent force of a spring 41, the vertical rod 27 declines and seals the inner hole 22, closed opening hole 28 opens and a cosmetics including the receiving part 11 will not discharge to the brush 43. The inner hole 22 and the opening hole 28 are open by pressing and releasing inner moving body 10 and the cone type elastic part 24 and the spring 41 that formed in the middle member 20 can be control freely discharge and interception of cosmetics by compressing and the middle member 20 that composed to a liquid transfer passage 21.
Abstract:
A fluid dispenser member designed to be associated with a fluid reservoir having a neck, said member comprising: a body defining at least part of a fluid chamber, said body being provided with fixing means for fixing onto the neck of the reservoir, said body including a fluid inlet connecting the inside of the reservoir to the fluid chamber; a pusher mounted on the body in such a manner as to be displaced axially between a rest position and a driven-in position; and a spring urging the pusher into the rest position, wherein the spring is housed entirely inside the pusher, and the body is made of a transparent or translucent material.
Abstract:
A fluid dispenser member having a dispensing wall (623) defining an outside surface and inside surface, said wall being provided with a through dispensing orifice (625) connecting the inside surface to the outside surface, the inside surface forming a leaktight slide cylinder for a piston (632, 633) suitable for moving in leaktight contact inside said cylinder for selectively unmasking the dispensing orifice, said piston forming a wall element of a fluid chamber inside which fluid is selectively put under pressure, said fluid dispenser member being characterized in that the inside surface extends over two surface segments, namely a top segment (6232) and a bottom segment (6242), the top segment having an inside diameter that is smaller than the inside diameter of the bottom segment, the dispensing orifice being formed at the top segment, and the piston being provided with a sealing lip (633) in leaktight sliding contact with the bottom segment.
Abstract:
The present invention is a dispenser adapted to be coupled to a fluid container. The dispenser comprises a dispensing head, an energy source, and a fluid pathway. The dispensing head includes a fluid pump, a motor adapted to power the pump, a trigger adapted to control the motor, and a nozzle orifice in fluid communication with a discharge end of the pump. The fluid pathway has one portion in fluid communication with an intake end of the pump and another portion inside the container.
Abstract:
With the subject invention, a pump is formed that generally includes a reservoir formed to accommodate at least one fluid dose, and a fluid-collecting chamber in fluid communication with the reservoir. The fluid-collecting chamber includes a dose-control portion which encompasses a volume defined by two dimensions. A first piston is disposed to urge fluid from the reservoir and at least into the dose-control portion. A second piston is disposed to reversibly slide within at least the dose-control portion of the fluid-collecting chamber. A nozzle is also provided which is located such that fluid displaced by the second piston from the dose-control portion is generally urged towards the nozzle. A check valve may be placed in the fluid path between the dose-control portion and the nozzle.

Abstract:
The invention relates to a dosing device with a medium reservoir. Dosing devices that comprise a medium reservoir and a pump device for dosing and dispensing a medium stored in the medium reservoir and pressure compensation means associated with the medium reservoir are known. According to the invention, the medium reservoir is provided with pressure-sensitive, flexible walls. The invention further relates to the use of said dosing device for dispensing pharmaceutical active substances.
Abstract:
A delivery container has a casing filled with a chemical liquid and a cap mounted on an upper end of the casing. A hollow cylinder having slots is disposed in and integrally formed with a lower portion of the casing. A tubular piston with a check valve is slidably disposed in the cylinder. The piston is connected to the cap, which has a discharge port, by a hollow shaft which extends vertically through an upper portion of the casing, so that vertical movement of the cap can be transmitted via the shaft to the piston. Inasmuch as the cylinder is disposed in the bottom of the casing, the cylinder is filled at all times with the chemical liquid which is supplied via the slots by gravity. The chemical liquid does not need to be drawn upwardly, and can be discharged in a constant quantity from the discharge port in one cycle of operation of the delivery container.
Abstract:
A fluid pump dispenser includes a spring biased pump piston having a generally hollow stem and reciprocable between pressure and return strokes within a pump cylinder therewith defining a variable volume pump chamber for dispensing fluid through a discharge opening at an outer end of the stem. The stem defines a valve controlled discharge passage leading from the pump chamber to the discharge opening. A driver nut may be mounted adjacent the pump piston and include at least one flange engaged with at least one respective spiral turn on a spindle disposed within the pump chamber to thereby rotate the spindle during reciprocation of the pump piston. A dip tube may be disposable within a container and affixed to the spindle for rotation with the spindle. A figurine may be mounted onto the dip tube for complementary rotation with the dip tube and the spindle.
