A two aerosol can injection system has a first aerosol can containing product and propellant; a second aerosol can containing activator or hardener; and a connector connected at a first end to the first aerosol can and at a second end to the second aerosol can. The connector has a first internal thread valve connected to the first aerosol can, and a second internal thread valve connected to the second aerosol can.

A two aerosol can injection system has a first aerosol can which contains activator or hardener and a second aerosol can containing product such as paints, thinners, clear coats, and propellant. A connector system connects at a first end to the first aerosol can and at a second end to the second aerosol can which provides flow of activator or hardener from the first can to the second can.

Heads for an aerosol container are disclosed. The head comprises a handle body having a base configured to be coupled to the aerosol container, an outlet, a flexible tube housed within the handle body. The flexible tube is configured to provide fluid communication between the container exit of the aerosol container and the outlet. And the head further comprises an elastically deformable actuator comprising a lever arm, and a coupling portion integrally formed with the lever arm and configured to be mounted around the flexible tube, wherein the coupling portion is further configured such that when the lever arm is deformed by a user, the coupling portion actuates on the valve body of the aerosol container. Aerosol containers comprising such heads and kits for treatments skin lesions are also disclosed.

A hand-held cosmetic dispenser having a housing with a first end and a second end, the housing having a nozzle coupled to a first end of the housing, a power source disposed within the housing, a spray button coupled to the housing, a cosmetic fluid compartment disposed within the housing and configured to receive and retain a fluid cosmetic, a gas compartment configured to receive and retain a gas cannister, and a gas controlling system disposed within the housing. The gas controlling system having a control mechanism that controls how much gas can leave the gas cannister. The power source is electrically coupled to the spray button and the gas controlling system. A method of using the same.

The present invention relates to a nebulizer, such as a spray can, for the topical application of a liquid and/or solid to a surface. The nebulizer is characterized by a valve comprising a mixing chamber designed for forming a colloidal mixture comprising a dispersed phase consisting of a liquid and/or a solid substance and a continuous phase consisting of a propellant gas before delivering the colloidal mixture to the nozzle. The invention also relates to a method for the topical cooling of the skin of a person or animal. In addition, the invention relates to various other uses of the device.

A foam transfer or dispensing device is described which dispenses foam from a source of foam, typically a pressurised canister, and which enables efficient purging or air and an initial volume of foam from the device to ensure foam sterility and quality when a syringe is filled from the device. The device comprises a foam inlet arranged for communication with a source of foam, a foam pathway in fluid communication with the foam inlet and comprising a foam outlet, arranged for engagement by a syringe nozzle; and a waste outlet in fluid communication with the foam pathway. The foam pathway comprises a tubular projection arranged to extend through the foam outlet and into a syringe nozzle when a syringe is connected to the foam outlet, which improves the efficiency of the purging process and prevents pooling of air or foam. The device further comprises a means for restricting displacement of material through the waste outlet, so that the user can control the volume of foam that is wasted.

A two aerosol can injection system has a first aerosol can containing product and propellant; a second aerosol can containing activator or hardener; and a connector connected at a first end to the first aerosol can and at a second end to the second aerosol can. The connector has a first internal thread valve connected to the first aerosol can, and a second internal thread valve connected to the second aerosol can.

Aspects of the disclosure are directed to apparatuses and/or methods involving a rotatable dial and a plurality of nozzles therein. The dial aligns each nozzle with a fluid supply channel. In some instances, a gear coupled to the dial has cogs and gaps between adjacent ones of the cogs along a rotational path of the gear. Certain aspects involve force feedback in which a flexible tab located in the rotational path of the gear engages with the cogs for providing resistive feedback. Other aspects involve audible feedback in which a flexible tab flexes in response to contact with the gear as it rotates, and snaps back into place after the gear is rotated past the flexible tab, creating an audible noise. Certain particular aspects involve utilization of the gears to prevent fluid from being dispensed when the nozzles are not aligned with the channel.

Provided is a multilayer-structured discharge container having a simple structure, capable of facilitating the loading of a substance to be contained and a pressurizing agent, and capable of facilitating the ejection of the pressurizing agent after use. A discharge container in which a valve mechanism is provided with a stem having two independent in-stem paths, one in-stem path communicates with an in-holder discharge path, the other in-stem path communicates with an in-holder gas path, a contained substance is discharged by closing the other in-stem path, and the pressurizing agent is ejected by opening the other in-stem path. The discharge container is capable of causing a pressurization chamber and the atmosphere to communicate by removing a push-button from a valve assembly and pressing down a stem of a valve mechanism (switching operation).

System and method for monitoring hand hygiene of a user. The system includes a handheld electronic device for being carried by the user to generate device data such as location data. A portable dispenser assembly is worn by the user to dispense disinfectant fluid from a container in a plurality of dispensing events. The assembly includes an electronics unit that generates event data relating to the dispensing events. The assembly is separate from the handheld electronic device yet configured to communicate with the handheld electronic device. A monitoring system receives the device data and the event data relating to the dispensing events for evaluating the hand hygiene of the user.
