bsorbed the water in the mug begins to boil and a pleasant aroma of coffee emanates from the microwave oven. When the microwave oven turns off, the filter bag deflates rapidly. The mug may be removed, it's temperature being only slightly warm; then the disposable brewing device may be removed and discarded since the handle of the disposable brewing device is so designed as to absorb very little microwave energy. The length of time needed to brew a mug of coffee is dependent upon the initial water temperature, very short periods may be obtained if one begins the process with very hot water. Using this invention, the above method for brewing is the preferred one; however, sensible heat may be added by means such as a hot plate or a open flame.
Included in the objects of this invention are: To provide a disposable coffee brewing device for individually brewing a single mug of coffee, the coffee grounds being at all times kept submerged in water. To provide a disposable coffee brewing device for brewing a piping hot mug of coffee which may be consumed without discomfort due to a overly heated drinking mug. To provide a disposable coffee brewing device which in addition to having a primary utility inside a microwave oven nonetheless retains function with equal facility by other means of heat infusion. To provide a disposable coffee brewing device which when placed inside a microwave oven brews a tasteful mug of coffee in a short period of time and does so unattended.BRIEF DESCRIPTION OF THE DRAWINGS
The description of this invention is to be read in conjunction with the following drawings.

The invention will now be described by referring to a preferred embodiment. In FIG. 1, a bag 10 made out of a filtering material of suitable porosity contains within and completely seals therein a premeasured amount of ground coffee beans 11. The bag is constructed from a rectangular filter material folded along edge 15 and sealed with a continuous seam 14 along the top of bag 10, then extending vertically along 12 and completing the enclosure with the lower seam 13. A portion of the length of the vertical seam 12 is securely attached to a thin elongated rectangular support element 23; attachment is made along approximately three quarters of the length of the vertical edge 12 and the middle region of inner surface 24 of support element 23. The attachment between vertical seam 12 and support element 23 extends continuously from the upper end as at 26 to the lower end as at 27 and so creates in fact a hinge which allows bag 10 to move freely from side to side in respect to surface 24 of support element 23. The unattached upper length along edge 12 of bag 10 extends freely above the hinge terminus support at 26. The thin elongated rectangular element 23 extends for a suitable distance beyond the lower terminus 27 of the hinge which is coincident with the corner formed by edges 12 and 13 of bag 10; the length of extension to the end at 28 of support element 23 will become evident in the subsequent description of FIG. 2. The obtuse surface 25 of support element 23 has attached to it a thin elongated rectangular tab element 30, located at the upper end of support element 23. Surface 31 of tab 30 is in solid attachment to surface 25 of support element 23 in region of common area 32. A separation line occurs at 33 between the support element 23 and the tab element 30. It is evident to those versed in the art that the support element and the tab element can be manufactured as one integral part and serve the same essential functions that are discussed in this disclosure. At the unattached end 34 of tab 30 there is a wedge shaped cut-out as at 35, this cutout connects with a rectangular cutout 36, a narrow passage 37 thus interconnects the two abutting cutout areas. The support elem
