ABSTRACT:
A safety lock in a steam pressure coffee maker is disclosed. The safety lock comprises a piston fitted in an orifice of the coffee maker body. When the pressure in the coffee maker chamber is sufficiently high, the piston is moved causing the piston rod to enter recesses provided along the periphery of a threaded plug which closes the main aperture. With the piston rod in this position, the threaded plug cannot be turned, thereby ensuring that the main aperture remains closed until the high pressure conditions no longer prevail.
