Abstract
A dispenser apparatus, including a can formed with an interior region to store pressurized fluid therein and a discharge valve coupled to the can. The discharge valve is able to move relative to the can in order to discharge pressurized fluid from the interior region of the can. A button is positioned to engage and move the discharge valve relative to the can to discharge pressurized fluid from the interior region of the can. A cap, including a shell coupled to the can and a button support coupled to the shell, is formed to include a chamber having walls that receives the button therein. The button is supported in a spaced-apart relation from the discharge valve during coupling of the shell to the can to maintain the button in a position disengaged from the discharge valve until a first engagement of the button and the discharge valve to discharge pressurized fluid from the interior region of the can, thereby preventing accidental release of can contents, known as huffing, when the cap is coupled onto the can.
