  • Patent number: 5778765
    Abstract: The invention is directed to a beverage brewing apparatus having a water reservoir (1) and a pump (6) powered by an electric motor (45), the pump pressurizing water from the water reservoir (1) and delivering it to a flow-through heater (11) heated by an electric heater (14). In the flow-through heater (11), water is heated in a water conduit (13) and subsequently fed to a pressure chamber (35), adapted to be filled with coffee grinds, of a brewing unit (34) from which, following an extraction operation, the brewed coffee flows into a receptacle (38, 39). According to the invention, a valve device (20) opening when a predetermined pressure is exceeded is provided in the fluid path (9, 13, 15) between the flow-through heater (11) and the brewing unit (34).

  • Patent number: 5775204
    Abstract: The invention is directed to a tea filter assembly (10) adapted to be fitted to a coffee maker (18) in place of a coffee filter in order to be able to make tea with the coffee maker (18). It is known in the art to provide such a tea filter assembly (10) with a first valve (36) for closing an outlet (44) from the tea filter assembly (10) while the tea is steeping. It is a disadvantage in such a type of tea filter assembly (10) that upon termination of the steeping time hot water continues to be discharged from the coffee maker (18), flowing over the tea leaves and extracting bitter principle in the process. To avoid this drawback, provision is made in the invention for a water conduit (14) through which hot water exiting the coffee maker flows straight into a carafe after the steeping time has ended, without coming into contact with tea leaves contained in a tea basket (16).

  • Patent number: 5752618
    Abstract: The invention is directed to a carafe (10) for carrying a beverage, with a vessel (12) formed in particular from glass and having at its opening an upper rim (26) upon which a plastic ring structure (28) is seated. Because the thermal expansion of plastics is about 20 times greater than that of glass, the seat of the plastic ring (28) on the vessel (12) may work loose due to the effect of changing temperatures to which the carafe (10) is exposed as when hot or cold beverages are filled in. In order to ensure a consistently firm seat also at varying temperatures, it is proposed in the invention that the plastic ring structure (28) be provided with inner (30, 36) and outer (38) detent means rearwardly engaging inner (20) and outer (24) undercuts of the vessel (12).

  • Patent number: 5749165
    Abstract: An electric pressing iron in which a plate-shaped soleplate made of an aluminum material with a low silicon content is bonded to the iron body by a temperature-resistant adhesive, wherein the surface of the soleplate is provided with a hard and wear-resistant aluminum oxide coating. Because the soleplate is made of an aluminum material with a low silicon content, anodizing produces an aluminum oxide coating of a particularly uniform coloring, with a temperature-resistant as well as corrosion- and scratch-resistant ironing surface that affords particular economy of manufacture.
