Abstract
Embodiments provided herein address these and other issues by providing a coffee filter support device that, when positioned placed at least partly in a coffee basket, provides a contact surface that prevents the coffee filter from collapsing inward during the brewing process. In one embodiment, the coffee filter support device has a frustoconical shape defined by a first aperture and a second aperture smaller than the first aperture.
Claims18
A method of using a coffee filter support device, the method comprising:
- positioning the coffee filter support device at least partially in a coffee filter basket of a coffee brewing machine, wherein:
- the coffee filter support device comprises a sloping body having a frustoconical shape comprising a contact surface and defining a first circular aperture and a second circular aperture smaller than the first circular aperture, and
- an angle between a contact portion of a contact surface of the sloping body and a surface parallel to the first circular aperture is less than 70°;
- and
- the coffee filter support device is positioned at least partially in the coffee filter basket such that contact between the contact portion of the contact surface of the sloping body and a coffee filter, a rim of the coffee filter basket, or both, holds the coffee filter support device in place, wherein the contact portion of the contact surface further prevents at least a portion of the coffee filter from collapsing inward during brewing;
- and
- brewing coffee with the coffee brewing machine.

A coffee filter support device, comprising:
- a sloping body comprising a food-grade, heat-resistant plastic having a frustoconical shape comprising a contact surface and defining a first circular aperture and a second circular aperture smaller than the first circular aperture;
- wherein:
- a contact portion of the contact surface is configured to, when placed at least partially in a coffee filter basket of a coffee brewing machine:
- contact a coffee filter, a rim of the coffee filter basket, or both:
- hold the coffee filter support device in place, and
- prevent at least a portion of the coffee filter from collapsing inward during brewing;
- a diameter of the first circular aperture is greater than 4 inches and less than 4½ inches;
- a diameter of the second circular aperture is less than 4 inches and greater than 3 inches;
- and
- an angle between the contact portion of a contact surface of the sloping body and a surface parallel to the first circular aperture is between 50° and 70°.

A coffee brewing machine, comprising:
- a coffee filter basket;
- and
- a coffee filter support device;
- wherein:
- the coffee filter support device comprises a sloping body having a frustoconical shape comprising a contact surface and defining a first circular aperture and a second circular aperture smaller than the first circular aperture;
- and
- the coffee filter support device is permanently or detachably coupled to the coffee brewing machine such that the coffee filter support device is positioned at least partially in the coffee filter basket while the coffee brewing machine is brewing, such that contact between a contact portion of the contact surface of the sloping body and a coffee filter, a rim of the coffee filter basket, or both, holds the coffee filter support device in place, wherein the contact portion of the contact surface further prevents at least a portion of the coffee filter placed within the coffee filter basket from collapsing inward during brewing.
