A water gun or toy water gun for dispensing liquid is disclosed. The gun includes at least one liquid dispensing outlet and at least one chamber housing that defines at least one chamber for storing liquid to be dispensed through the liquid dispensing outlet. For replenishing with liquid in a fast and convenient manner, the chamber is designed to be substantially uniform in cross section. An opening through which the liquid may be received in the chamber is also substantially the same size as the cross-section of chamber. The gun includes a lid that is pivotally movable between a closed position in which at least a portion of the opening is concealed by the lid and an open position in which the at least a portion of the opening is revealed by the lid.

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.

An aerosol-generating system may include a device body and a cartridge configured to be removably inserted into or connected to the device body. The device body may include a power supply and an electrical heater connected to the power supply. The cartridge contains an aerosol-forming substrate in the form of a thermoreversible gel that is a solid at room temperature.

A container comprising concavity in which a container neck is situated, inset from the top of the container, such that a pump assembly may be fastened to said inset neck resulting in a more discreet form, a container design that is less overpowered by protruding a protruding pump, and a more volume-efficient assembly. Additionally, space between the pump assembly and a peripheral wall of said concavity is reserved such that an annular wall of a pump head may move within said space when the pump head is pressed to dispense the contents of the container.

A fluid dispersal system with integrated UV lighting includes a reservoir of fluid, a sprayer head connected to the fluid reservoir, a nozzle, and an ultraviolet lighting element. The nozzle is supported by the sprayer head and is in fluid communication with the reservoir to disperse fluid from the reservoir in a spray direction. The ultraviolet lighting element is supported by the sprayer head adjacent the spray nozzle, and directs ultraviolet light in a direction generally parallel to the spray direction. The nozzle and the lighting element may be actuated such that ultraviolet light is directed onto a surface while fluid is simultaneously dispersed onto the surface.

Flairosol dispensing devices are presented. They utilize a combination of Flair technology, precompression valves and aerosol like pressurization of the dispensed liquid. An exemplary device has a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring, 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, which serve to prevent backflow. A dome valve can be provided near the outlet channel at the top of the dispensing head, such that once its pressure is exceeded by the liquid, it opens and allows for a spray. Alternatively, in an activated embodiment, the dome valve is locked unless opened by a user.

A cartridge for a dispensing device, such as a nebulizer, for dispensing a medicament composed of or produced from a plurality of components and a system including a dispensing device, such as a nebulizer, and such a cartridge. The cartridge includes at least two fluidically separated chambers which each contain at least one component of the medicament, an actuating mechanism for fluidically connecting the chambers and mixing the components for the dispensing of the medicament. A method for preparing a medicament composed of a plurality of components in a cartridge for the dispensing of said medicament by way of a dispensing device, such as a nebulizer, where a plurality of fluidically separated chambers of the cartridge are fluidically connected, and a component of the medicament is at least partially transferred from one of the chambers to another of the chambers with another component of the medicament in order to mix the components. Only once the components have been mixed is the cartridge opened for the extraction of a dose of the medicament.

A fluid distribution assembly includes a reservoir that may contain a fluid. A pump is coupled to the reservoir such that the pump may be manipulated thereby facilitating the pump to selectively pressurize air within the reservoir. A hose is fluidly coupled to the reservoir such that the hose may selectively release the fluid within the reservoir when the pump pressurizes the air within the reservoir. A nozzle is fluidly coupled to the hose such that the nozzle may be manipulated. Thus, the nozzle to selectively allows and restricts the flow of the fluid from the hose. A cap is removably coupled to the reservoir such that the cap may allow the reservoir to be filled with the fluid. A handle is coupled to the reservoir.

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 hair care device according to the present disclosure includes a tank that stores a liquid, a liquid feed pump that outputs the liquid stored in the tank, and a controller that controls an output of the liquid feed pump. The hair care device according to the present disclosure further includes a detector that detects torque of the liquid feed pump. The controller adjusts the output of the liquid feed pump based on a detection value of the detector. Thus, the hair care device that suitably sprays a cosmetic component is provided.
