FILTER ELEMENT HAVING MICROPERFORATIONS FOR ENABLING THE PASSAGE OF FLUIDS DURING BREWING

摘要

The present invention relates to a filter element for the extraction or brewing of beverages. In particular, the filter element facilitates brewing through increased permeability of fluid from a brewed beverage from brewable particles, such fluid including liquid and gas, and the easing of gas build up in a brewing device herein by the removal of gases emitted from a beverage medium housed within a beverage cartridge during brewing. The filter element may be used within a rigid, semi-rigid or soft pod that is insertable within a beverage brewer. The invention particularly concerns the brewing of coffee and coffee products in a coffee brewing machine configured to receive pods holding coffee particles that are injected with water and caused to brew coffee therefrom.

主权项

1. A beverage cartridge for use in a beverage maker, comprising:
a. A chamber, said chamber having at least one substantially enclosed portion, said at least one substantially enclosed portion having a base with a perimeter and a wall connected to said perimeter of said base, said chamber being configured to receive and house a beverage medium therein; b. A beverage filtering device, having
i. A filter carrier device operatively connected to said chamber, said filter carrier being positioned within said chamber;ii. A filter element having a first surface and a second surface positioned oppositely to said first surface, said second surface being at least partially attached to said filter carrier, said filter element having a plurality of microperforations positioned through said filter element, said plurality of microperforations extending from said first surface to said second surface of said filter element; and c. A sealing element positioned onto said wall of said chamber whereby said beverage cartridge is sealed and thereby enclosed; whereby said beverage filtering device increases the permeability of fluid flowing through said beverage cartridge during brewing.
