A plug for a power consumer is positioned centrally in a recess in a bottom of the power consumer and rests in a flange at an edge of the recess. The plug has a first portion and a second portion that can be rotated relative to each other about a common axis perpendicular to the bottom. The first portion of the plug has a plurality of fish plates extending outwardly from its sides, each fish plate having a recess. The second portion has a plurality of hooks, each having a protuberance. By rotation of the second portion relative to the first portion the protuberance of each hook is engaged in the recess of the respective corresponding fish plate.

According to this invention, this objective is met by a gasket ( ) which is made from a soft plastic and has a central sleeve ( ), the diameter of which is tightly fitted to the ascension pipe ( ), as well as an outer, bell-shaped flange ( ) with a shoulder ( ), a skirt ( ), a bead ( ), and a flat part ( ) linking the shoulder ( ) of the bell-shaped flange ( ) with the central sleeve ( ), and where the bead ( ) has been manufactured with internal fastening devices ( ), which have been designed to hook into corresponding fastening devices ( ) on the funnel ( ), fastening the gasket ( ) on the funnel ( ), where the shoulder ( ) of the bell-shaped flange ( ) has a diameter greater than that of the skirt ( ) of the bell-shaped flange ( ), but smaller than the diameter of the bead ( ).

Base construction for a coffee making apparatus

A piston-type coffee maker is disclosed having a cylindric container, a lid, a piston with piston rod and a handle, where the piston is made as a filter for the ground coffee. The piston coffee maker is adapted for making a single cup of coffee and for keeping the temperature of the infusion fluid at a suitable level during preparation of the coffee. The piston coffee maker is also adapted to be manufactured at low cost. The walls, lid and bottom of cylindrical container are made heat isolating. An upper rim of the cylindrical container has a locking member that cooperatively engages a corresponding locking member on the lid.

A device for preparing beverages of the type having a closed compartment (c,), an open compartment (c,), an ascension pipe (,) connecting the compartments, and a filtering device (f,) between the ascension pipe (,) and the open compartment (c,), has some disadvantages in that an external heating source is needed, thereby increasing the risk of fire and burning the operating persons. Further, the infusion time is either fixed, being decided by the distance between the lower orifice of the ascending pipe and the bottom of the closed compartment or left to the user to estimate. In order to avoid these problems the bottom of the closed compartment (c,) has at least two levels (H,, H,), one level of diminished elevation (H,) in a relatively small area around the lower orifice of the ascension pipe (,), the level (H,) of which is at least below the other elevated level (H,) of a relatively large area, the large area being equipped with electrical heating members (he,, he,) controlled by a switch and at least one temperature sensor (v) for controlling the switch, the large area of the bottom being surrounded by a rim (,) for holding a residual of liquid.
