Embodiment Construction

[0040]The novel features of the present invention will become apparent from the following description of the preferred embodiment, and as illustrated in FIGS. 1 through 14. One embodiment of the claimed invention is an hourglass-shaped cold brew coffee apparatus 10, which comprises a filter 11, 41 a brew chamber 12, and a carafe assembly 13. The carafe assembly 13 is comprised of a middle unit 14 and an extract chamber 15. The cold brew coffee apparatus may comprise other shapes and designs for the middle unit 14, brew chamber 12 and extract chamber 15.

[0041]Referring to FIG. 2, the filter may comprise an extruded frame 44 encasing a water-permeable barrier 43 having a gasket 42 attached to the rim to form a hermetic seal between the inner volume of the filter and the inner volume of the brew chamber. The extruded frame further comprises a substantially flat surface having four leg members 22 to form a base opposite the rim. The leg members 22 act as feet to form a base for the filt...

Abstract

The invention provides an hourglass shaped apparatus for cold brewing coffee, comprising a brew chamber, and extract chamber and a middle unit connecting the brew and extract chambers. The extract and brew chambers comprise two ends of the hourglass shaped middle unit. The brew chamber houses a free-standing self-contained filter containing coffee grounds inside a water-permeable barrier. Water is poured into the brew chamber to generate coffee extract through cold water infusion. After the brewing process, the apparatus is inverted, and the coffee travels into the extract chamber through the middle unit for dispensing. Coffee brewed in this manner is less acidic and more flavorful than the conventionally hot-brewed beverage. All the components of the apparatus, the filter, the brew chamber, the extract chamber, and the middle unit, are detachable.

Description

CLAIM OF PRIORITY[0001]Pursuant to 35 U.S.C. § 120, this application is a continuation-in-part of U.S. application Ser. No. 11 / 406,742 filed on Apr. 18, 2006 and published on Oct. 19, 2006 as US 2006 / 0230944 A1.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention generally relates to an improved apparatus for brewing coffee and more particularly to an improved apparatus that cold brews coffee to produce an infusion of coffee extract, and also stores and dispenses coffee.[0004]2. Description of Related Art[0005]Apparatuses for brewing coffee are well known in the art. In the known art, coffee is customarily drip-brewed using heated water. Water is heated in a vessel, and then poured over a container of ground coffee. As the water mingles with the grounds, a coffee extract is produced which drips through a filter into a coffee pot or cup. Improvements to the art have lead to machines that automatically heat water and brew coffee in one self-contained d...
