Abstract: A bag-in-box container system includes a bag, a box, and a mechanism for fastening the bag and box combination. The bag may include a dispensing end with a collar and a groove. The box may have an opening through which a portion of the dispensing end protrudes when the bag is inside the box.

Abstract: A booth for automatic spray application of multiple liquids onto a human subject may include an HVLP nozzle including a nozzle tip, an air inlet port connected to an air pathway, a linear slide operably connected to a motor and to the HVLP nozzle, a plurality of check valves, and a controller, where the controller is operably connected to the motor and configured to cause the motor to move the HVLP nozzle vertically along at least a portion of the linear slide thereby adjusting the vertical position of the nozzle tip, where the controller is further configured to control an air source for causing air to flow through the air pathway, and where the controller is further configured to control one or more liquid sources for causing the first liquid associated with the first liquid inlet port from the multiple liquid inlet ports to flow through the first liquid inlet port from the multiple liquid inlet ports and the second liquid associated with the second liquid inlet port from the multiple liquid inlet ports to
