A fluid dispenser head having a single-piece head body (1) forming an axial inlet well (12) suitable for connecting to a dispenser member (D), such as a pump or a valve; and a transverse feed duct (13) that extends from the axial inlet well (12). The dispenser head also has a dispenser orifice (21) in fluid communication with the transverse feed duct (13). A filter (F) is situated in the axial inlet well (12) and/or in the transverse feed duct (13).

A fluid control device includes a piezoelectric pump, an inhaler, and a valve. The piezoelectric pump has a gas suction hole and a gas discharge hole. The inhaler has a container, an inhalation port, and a connection hole. The valve has a first ventilation hole, a second ventilation hole, a third ventilation hole, a first valve housing, a second valve housing, and a valve body. The first ventilation hole of the valve is connected to the connection hole of the inhaler. The second ventilation hole of the valve is connected to the suction hole of the piezoelectric pump. The third ventilation hole of the valve is opened to the atmosphere. The valve body is held between the first valve housing and the second valve housing, and configures a first region and a second region.

A nozzle for a spray gun, in particular a paint spray gun, has at least one material nozzle having a hollow portion for the passage of material to be sprayed; a material outlet opening; and a disk element extending radially from the material nozzle and having at least one passage opening. The nozzle has at least one first baffle disk which is arranged on the disk element and has an inner and an outer circumference. The first baffle disk is arranged on the disk element directly, in particular without a sealing element arranged inbetween. The disadvantages that separate sealing elements have to be specially produced and may be lost or damaged, can thereby be avoided. The nozzle according to the disclosure and related nozzle sets, paint spray guns and methods for producing nozzles are functionally reliable, have only few individual parts and a compact design and are quiet.

Illustrative embodiments employ catholyte scrubbers to provide higher concentrations of ozone in ozonated water than was possible in prior art systems and methods. Moreover, some embodiments employ scrubbers to increase the efficiency of production of ozonated water by producing such higher concentrations of ozone in ozonated water using the same amount, or less, power than prior art systems and methods. Some embodiments employ scrubbers to enable production of water with higher concentrations of ozone, and/or ozonated water in which the concentration of ozone decays more slowly, as compared to prior art methods.

A fluid dispenser device having a dispenser member mounted on the neck of a container, with a neck gasket interposed. The dispenser member is mounted by a fastener element having a fastener portion and a compression portion. The compression portion includes a projecting profile that exerts stresses on the neck gasket. After assembly, the neck of the container generates first stresses in the neck gasket, and the projecting profile of the fastener element generates second stresses in the neck gasket, the first stresses approximately axially opposite the second stresses. The neck includes a top curved margin and defines an edge in contact with the neck gasket, the first and second stresses approximately axially opposite but radially offset, such that said first and second stresses are balanced at least in part.

Provided is an elastic member according to an embodiment of the present invention. In the elastic member, a protrusion portion formed outward and a recessed portion formed inward may be repeatedly formed in a longitudinal direction, an outer groove may be formed in the protrusion portion along an outer circumference of the elastic member, an inner groove may be formed in the recessed portion along an inner circumference of the elastic member and guide bending-deformation of the protrusion portion and the recessed portion during elastic compression.

A cuboidal container for storing a liquid cosmetic substance includes a neck with an opening on an upper face of the container. A dispensing device is secured to the opening. The dispensing device is a pump connected to a dispensing head and a rising line guided in the interior of the container. A cap for the container has a cap upper face with a flat surface and a cap lower face with a first receptacle adapted for placement of the cap on the dispensing device. The cap lower face as a second receptacle designed as a three-sided pyramid designed to receive one of four corner regions on a lower face of the cuboidal container so that the container is held in the second receiving area in a form fitting and rotationally fixed manner in an aesthetically pleasing position when the cap is removed and resting on a flat surface.

The present invention relates to a pump head for a metering device for a metered dispensing of a fluid. The pump head can thereby be fitted on a storage container, for example a bottle, which is designed for storing the fluid to be dispensed. Pump head and storage vessel together thereby form the metering device according to the invention. The pump head is distinguished by including a passage for air, by means of which air from outside can be transferred into the storage vessel during the pumping process for pressure compensation. The present invention relates in addition to purposes of use for the pump head and the metering device.

A quantitative pressing sprayer includes a clamping plate, a pressing head, and a hand-held screw cap connected with a container. The pressing head penetrates through the hand-held screw cap. The clamping plate is pressed against and arranged on the pressing head. An end of the clamping plate is used as a fixed end that is connected with the hand-held screw cap. Another end of the clamping plate is used as a pressed end. The clamping plate drives the pressing head with the fixed end as a pivot of a lever. The pressed end and the fixed end form a first arm, the pressing head and the fixed end form a second arm, and the first arm is longer than the second arm.

A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide data to the processor. The processor is configured to recall information from the memory, to compare the information to the data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison.
