Dispensing devices are provided. Such devices utilize a combination of Flair? technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. An example dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. Liquid exiting the piston chamber under pressure enters a central vertical channel which is in fluid communication with both the pressure chamber and a dome valve, with pre-defined opening pressure, provided near the outlet channel at the top of the dispensing head.

A dispensing system includes a motor driven air pump having an air inlet and an air outlet, and a dispensing device. The dispensing device is releasably connected to the air pump. The dispensing device includes an air connector connected to the air outlet of the pump, a mixture outlet, a product inlet, and a product uptake system connected to the air connector, the mixture outlet, and the product inlet. The dispensing system includes a product container for a product to be dispensed. The product container is connected to the product inlet. The product container is integrated in the dispensing device. The product uptake system may include an ejector for sucking product from the container and/or a container air inlet for pressurizing the container.

The sprayer comprises a container (1) intended to hold liquid for forming the cleaning mass and pressurized air for spraying it, the container (1) being dismantlably attachable to a head (3) bearing a manual pump (4) to increase the pressure of the air, the head (3) also having a supporting handle (23) with a pushbutton (24) operating the outlet valve (18) for the cleaning mass to the delivery nozzle (22), the sprayer having a manually replaceable mixing device (7, 26) located between the outlet conduit (8) for the liquid from the sprayer container (1) and the outlet of damping mass (20) controlled by the manual valve (18), the mixing device (7, 26) having different passage cross-sections for the liquid and the air present in the container (1) in order to adjust the sprayer to provide cleaning masses with a drier or wetter foam consistency.

Systems and methods for suppressing vaporization of a volatile fluid dispensed from a pressure vessel are provided. The system includes an evaporator coupled in thermal communication with a first flow of volatile fluid from the pressure vessel and in fluid communication with a second flow of volatile fluid from the pressure vessel. The evaporator includes at least one channel therein for channeling the second flow of volatile fluid therethrough. In addition, the system includes a compressor coupled in fluid communication with and downstream from the at least one channel. Moreover, the system includes a return line coupled in fluid communication with an outlet of the compressor. The compressor is configured to compress the second flow of volatile fluid and channel the compressed second flow of volatile fluid to the pressure vessel via the return line.

The present invention relates to pathogen cleaning and simulation of pathogen spreading. More particularly, some implementations of the described invention relate to systems and methods for spraying materials in a manner that mimics the spreading of pathogens from coughing or sneezing. Some implementations further relate to using a non-aerosol sprayer that produces both a mist and droplets of a mixture containing water, a fluorescent marker, a surfactant, and an antifoaming agent. In some cases, the pump sprayer defines an internal compartment that includes the mixture. In some cases, the sprayer further includes a pump mechanism that is configured to be pumped to compress a gas within the compartment and a release valve that is configured to release pressure within the compartment through a spray nozzle of the sprayer such that droplets and mist of the mixture are sprayed from the nozzle. Other implementations are also described.

A liquid spraying device including a tank configured to store liquid, a spraying device including a discharger configured to discharge the liquid in a form of a mist, a first flow path forming part disposed between the tank and the discharger and forms a first flow path of the liquid, a pump provided midway of the first flow path, and feeds the liquid from the tank toward the discharger, and a second flow path forming part configured to form a second flow path that branches off from the first flow path at a branching position between the pump and the discharger, and returns to tank. The first flow path forming part includes a small sectional-area part between the branching position of the first flow path and the discharger, the small sectional-area part forming a flow path having a sectional area smaller than a sectional area of the second flow path.

A portable, self-pressurizing sprayer or shower system includes a pressure container within a tank. Pressurized fluid, such as water from a residential water tap, is fluidly connected to the pressure container to fill and pressurize the system with the fluid. The sprayer system is then disconnected from the pressurized fluid source and transported to a remote location. A tube is then fluidly connected to the pressure container and the pressurized fluid is released through the tube to provide a portable sprayer system. A heating probe is provided that is removably secured to a second port in the pressure container. A fill kit is provided to fill the pressure container with a fluid, and then a pump is used to pressurize the system when a pressurized fluid source is unavailable.

In exemplary embodiments of the present invention, Flairosol dispensing devices can be provided. Such devices utilize a combination of Flair technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. Such a dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container, for example, the inner container of a Flair bottle, and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve, which serve to prevent backflow. Liquid exiting the piston chamber under pressure (supplied by a user pumping the trigger) enters a central vertical channel which is in fluid communication with both the pressure chamber (above the pressure piston) and a dome valve provided near the outlet channel at the top of the dispensing head. The dome valve has a preset pressure, such that once exceeded by the liquid, opens and allows for a spray. If the liquid pressure drops below such preset pressure, the dome valve closes off the outlet channel, which serves to regulate the strength of the flow and preclude leakage. Alternatively, in an activated embodiment, for example, once the liquid is sufficiently pressurized, it can be dispensed by a user allowing the dome valve to open by pressing on an activation button that removes a dome lock.
