A fluid dispenser device including an outlet, a pocket having an interior volume for containing a fluid, the interior volume being delimited at least in part by a movable wall, a reservoir arranged to contain the fluid, a pocket cap, a cavity, a reservoir orifice joining the reservoir and the cavity; wherein the pocket cap is arranged to be mounted by insertion in the cavity of the device so as to be mounted by extending: by passing through the pocket at least partially while passing through the movable wall orby going along the pocket at least partially, the device comprising an inlet orifice arranged to insert the pocket cap into the device from the outside of the device and opening into the cavity.

A dispensing system including a cap that is capable of securing the dispensing system to a bottle filled with a formula, wherein the cap is configured to retain a metered dose of the formula, a shaft in fluid communication with the cap, an accordion bladder inside the cap, wherein the accordion bladder includes at least one opening, one or more bellows, and a stopper, a distributor nozzle in fluid communication with the shaft, and an outer nozzle covering the distributor nozzle and configured to dispense the formula.

Bottles and atomizer configurations provide dispensers capable of atomizing a fluid or liquid contained in the bottle, wherein the bottles may include shapes and features to facilitate evacuation of the bottles and the atomizers provide improved features for storing and dispersing product from the bottles.

The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

The present invention relates to a folder type cosmetic container that can reduce waste of content in the container by dispensing a predetermined amount of the content when the content is pressed by a pressing-dispensing member, so it can be conveniently used. Further, the folder type cosmetic container can improve productivity, reduce the manufacturing cost, and improve convenience in use by employing a simple structure for dispensing a predetermined amount of content.

A mixing and dispensing apparatus having first and second containers. The first container has a main body portion which retains a first substance. A separate compartment is located in the first container and an internal passageway is formed between the main body portion and the compartment. The second container is configured to retain a second substance, and is compressible. The second container has a top end and a closed spout, wherein the closed spout is located in the compartment with the spout extending through the internal passageway into the main body portion of said first container. A release mechanism is formed by a plunger extending within the second container. The plunger has a first end in communication with the top end of the second container, and a second end aligned with the closed spout. The second end opens the closed spout when the second container is compressed to release the second substance into the main body portion of the first container.

A portable device heats a fluid within a reservoir. The device includes a housing, a cavity, and an energizing element. The housing includes a first longitudinal end, a second longitudinal end, and outer surfaces of the device. The outer surfaces extend from an outer portion of the first longitudinal end to an outer portion of the second longitudinal end. The cavity extends from a cavity port that is positioned on an inner portion of the first longitudinal end to a cavity terminal positioned intermediate the first and second longitudinal ends. Inner lateral surfaces are adjacent the cavity and extend from the inner portion of the first longitudinal end to an outer portion of the cavity terminal. The energizing element is around the cavity. The cavity is positioned intermediate a first energizing element portion and a second energizing element portion. The energizing element provides energy to the cavity.

A dispenser having a dispensing member connected to a main reservoir containing a first fluid product, the dispensing member communicating with a main axial outlet orifice, and a plurality of secondary reservoirs containing a second fluid product and each having a mobile wall, and a push-button that can be moved along an actuation axis, carrying with it the main outlet orifice. The push-button defines as many secondary outlet orifices as there are secondary reservoirs, the secondary outlet orifices being distinct from the main axial outlet orifice, each secondary outlet orifice being fed from a secondary reservoir in response to the movement of its mobile wall, which movement is brought about by the movement of the push-button along the actuation axis.

An actuator includes a diaphragm, a lower electrode on the diaphragm, an electromechanical transducer film on the lower electrode, and an upper electrode on the electromechanical transducer film. The diaphragm includes a first silicon oxide film having a thickness of 0.5 m or more, a silicon layer on the first silicon oxide film, a thickness of which is 3 m or more, and a second silicon oxide film on the silicon layer, a thickness of which is 0.5 m or more. A volume resistivity of the silicon layer is 10.sup.3 .Math.cm or more and 10.sup.6 .Math.cm or less.

A nozzle for a fluid delivery device includes a nozzle head. The nozzle head defines an inner head chamber for a fluid. The nozzle head has at least one nozzle opening through which fluid is configured to be selectively delivered from the head chamber to a target site during use of the device. The nozzle head is at least partially formed from a deformable material. The nozzle head is selectively deflectable between an opened condition in which the at least one nozzle opening is at least partially open to permit fluid flow therethrough and a closed condition in which the at least one nozzle opening is at least partially closed to restrict fluid flow therethrough.
