    Abstract: A coffee or tea making machine wherein the receptacle for fresh water has an open top which is reinforced by a frame supporting two pivotable covers having flat walls defining a narrow straight clearance and being pivotally connected to each other for movement between substantially horizontal positions in which they overlie the respective portion of the receptacle and second or open positions in which the pivoted cover overlies the other cover. The hinge between the covers has a one-piece plastic carrier with two pairs of studs or with two pairs of sockets which extend into or receive complementary sockets or studs at the inner sides of the covers.
