Abstract: According to this invention, this objective is met by a gasket (1) which is made from a soft plastic and has a central sleeve (8), the diameter of which is tightly fitted to the ascension pipe (5), as well as an outer, bell-shaped flange (9) with a shoulder (7), a skirt (10), a bead (11), and a flat part (12) linking the shoulder (7) of the bell-shaped flange (9) with the central sleeve (8), and where the bead (11) has been manufactured with internal fastening devices (3b), which have been designed to hook into corresponding fastening devices (3a) on the funnel (2), fastening the gasket (1) on the funnel (2), where the shoulder (7) of the bell-shaped flange (9) has a diameter greater than that of the skirt (10) of the bell-shaped flange (9), but smaller than the diameter of the bead (11).

Abstract: Regarding a base construction comprising a hot plate for a coffee-making apparatus of the type designed to have water brought to a boil in a closed container (1), whereupon the water is pressed through a riser pipe (12) into an open container (6), where boiling water extracts aromas and flavor from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container (1) through a filter placed at the outlet of the open container, the objective is to provide a sealed base construction which comprises a hot plate for a coffee-making apparatus where the hot plate does not suddenly boil dry, while the finished coffee beverage is carefully treated. Moreover, a reliable sealing of the hot plate must be provided, using simple means and without the use of tools.

Abstract: 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.

Abstract: An impression tray for taking impressions of transfers of dental implants comprises, in its closed face, a succession of removable segments secured by screws or by studs. After the impression material has set, the segment(s) giving access to the screw of the transfer is/are removed.

Abstract: Regarding a gasket for a funnel for a coffee-making apparatus of the type designed to have water brought to a boil in a closed container, whereupon the water is pressed through an ascension pipe into a funnel, where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container through a filter placed at the outlet from the funnel, the object is to provide a gasket (1) for the funnel (2) of a coffee-making apparatus of the type mentioned in the introduction, where the gasket is appropriately deformed at differences of pressure greater than a few hundred millimeters of water column with a view to limiting or equalising the difference in pressure. Moreover, the gasket must be easily disassembled with a view to cleaning or replacement, and it must be able to withstand the temperatures and chemical conditions arising during the preparation of coffee.

Moreover, a reliable sealing of the hot plate must be provided, using simple means and without the use of tools.

Abstract: With respect to a plug for a power consumer, in particular a coffee-making apparatus, with means for fastening such a plug in the power consumer, the objective is to provide a method for mounting the plug which is simple, can be carried out without tools, and requires relatively little time. It should, however, also be possible to use the same method on the base, where the corresponding part to the plug must be fitted.

Abstract: With respect to a filter with a fastening device for a coffee-making apparatus of the type where water is brought to a boil in a closed container, whereupon the water is pressed through a riser pipe into a funnel, where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container through a filter placed at the outlet of the funnel, where the filter is fastened by means of a fastening device which reaches through the riser pipe, the objective is to provide a filter where the aroma and flavour of the ground coffee is exploited as well as possible and where the filter offers a comparatively large filter surface for the finished coffee, and where the filter can easily be removed from the funnel and cleaned with a view to further coffee-making. Moreover, the filter must be easily replaceable by dismantling the handle and locking clip and fitting these on a new filter.

Abstract: A device for preparing beverages of the type having a closed compartment (c2), an open compartment (c1), an ascension pipe (23) connecting the compartments, and a filtering device (f1) between the ascension pipe (23) and the open compartment (c1), 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.
