A drain gun includes a handle and a trigger. The handle includes a channel and a plurality of inlets. The inlets feed the channel. The trigger causes a staged release of a plurality of fluids from a plurality of cartridges to the channel via the inlets when the cartridges are stored in the handle and feeding the inlets.

Provided herein is a safety and control device for pressure vessels for application devices for liquid media including a safety valve, a control device for the operating pressure, a pressure indicator, and a pressure relief, as well as a means for connecting the device to the pressure vessel, the device having a housing, which is provided with a compressed air supply and an air outlet, and a multifunctional slide arranged within the housing The multifunctional slide defines a channel, which is connected to a blind bore and a pin and at the end has means for relieving the pressure by manual actuation. A spiral spring encloses a pin and supports the multifunctional slide with respect to a bottom of the housing. Locking means enable the pin to be arrested in a position protruding from the housing .

A basket for securing a container to a dispenser has a device for connecting the basket with the dispenser and a device for connecting the basket with the container and a cylindrical seat for a valve of the container, wherein the basket provides a fluid connection between the container and the dispenser, wherein the basket provides a grip area for mounting the basket on the dispenser. The grip area is located on the cylindrical seat. The location of the grip area on the cylindrical seat reduces the height of the basket and improves the handling of the dispenser.

A sprayer apparatus for dispensing fluid from an aerosol spray can includes a tube which is couplable to a valve stem of the aerosol spray can. A spray can valve actuator is coupled to the tube and couplable to the spray can. The spray can valve is operable to depress the valve stem to fluidly couple a chamber of the aerosol spray can and the tube. A dispenser gun is attached to the tube and is operable to release the fluid supplied through the tube.

A handheld liquid spraying system includes a liquid container assembly having a container. An air inlet is configured to receive air to pressurize the liquid container assembly. A collapsible liner is disposed within the container. A cap has a first portion extending into an opening of the container and a second portion having an outlet for a flow of the liquid from the container. A fastening mechanism is configured to engage the container and retain the cap with a portion of the collapsible liner secured between the cap and the container. A liquid sprayer assembly is removably couplable to the liquid container assembly and includes a stem adapter, a stem adapter nut having a set of threads configured to engage a set of threads on the cap, a spray orifice, and a control mechanism configured to control flow of the liquid through the spray orifice.

A tank holding a quantity of liquid releasably connects to a portable pump assembly through a connector to provide a portable sprayer. The tank connects to a feed line that supplies spray nozzle with the liquid. The connector combines a quick disconnect connector with a pressure relief valve. The portable pump assembly includes an electric pump, a switch assembly, and a check valve. The portable pump assembly directs gas through the check valve into the connector to increase the gas pressure in the tank and force the liquid in the tank to flow through the feed line and out the spray nozzle. The switch assembly turns off the electric pump when the gas pressure in the tank exceeds a predetermined limit while maintaining the flow of liquid through the spray nozzle.

The present invention provides a personal defense device that is suitable for use by untrained and/or handicapped individuals when attacked. The device may be used by law enforcement personnel with a reduced chance of accidental discharge of a firearm. A strap is provided that fits around the wrist or another limb of the wearer. A controller is mounted to the main body along with an actuator and a pressurized gas reservoir. A housing is mounted to the main body to protect the components and may be removable. The device may be motion activated by an accelerometer connected to a circuit or other computer that recognizes a preprogrammed set of movements. The device may be voice activated or physically triggered by the user. The controller may provide at least one data function such as time stamping, geolocation, emergency texting, cell service, web access and Bluetooth compatibility.

Vapor sunglasses are configured to dispense vapor to a user; the vapor sunglasses have a first frame joined to a second frame. The first frame has a first lens and the second frame has a second lens. A first heat switch is arranged on the first frame. A first hollow mouthpiece is joined to the first frame with a first hinge. A first temple tip is joined to the first frame with a first temple tip hinge. A first cartridge tank is arranged inside the first frame. A first atomizer is connected to the first cartridge tank and a first battery. A first charge port is connected to the first battery. Engaging the first heat switch causes the atomizer to atomize material in the first cartridge tank into a vapor that is discharged through the first hollow mouthpiece.
