DETAILED DESCRIPTION OF THE PREF~ ED_EMBQDI~MENTS
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, Figures 1 and 2 illustrate a coffee bag 10 that consists of a portion of very fine ground coffee 12 for making an individual cup of coffee 14. A
housing 16 is provided and is fabricated out oE two sheets of water permeable paper material 18 heat sealed around its perimeter 20 in a face to face relationship for holding the very fine ground coffee 12 therebetween.
As shown in Figure lA the housing 16 of the coffee bag 10 can further include a plurality of compartments 22, here sbown as three, being heat sealed at 24 therebetween to increase flow through action of hot water past the very fine ground coffee 12 in each of the compartments 22 when making the individual cup of coffee.
Figure 3 to 6 show another type of cofEee bag 26 that consists of a portion of very fine ground coffee 28 for making an individual cup of coffee. A cylindrical housing 30 is provided, which has an open top 32 and is fabricated out of water-permeable paper material 34 for holding the very Eine ground coffee 28 therein. A perforated disc 36 is heat sealed at 38 around perimeter of the open top 32 of the housing 30.
The coffee bag 26 also includes a pair of spring strips 40 each of which is vertically suspended from an opposite edge of the perforated disc 36 and is attached along side of the , housing 30. ~hen the housi~g is inserted within ~ cup of ho-t water the spring strips 40 will extend downward].y to help the housing 30 to go from a collapsed position as shown in Figure 3 to an extend position as shown in Figure ~. Also shown is a device 42 for agitating the very fine ground cofEee 28 is ~ithin the housing 30.
The device 42 consists of a member 44 that has a plurality of radial fingers 46 located in bottom 48 of the housing 30 below the very fine ground coffee 28. An elastic cord 50 extends upwardly from center of the member 44 and out through the perforated disc 36. When a person pulls the elastic cord 50 after the housing 30 is inserted within the cup of hot water the member 44 with the radial fingers 46 will agitate the very fine ground coffee 28.
An eyelet 52 is mounted adjacent to top center of the perforated disc 36. A hook 54 is attached to free end of the elastic cord 50 so that when the housing 30 is in the collapsed position the elastic cord 50 i8 wrapped from top to bottom around the housing with the hook 54 engaging the eyelet ~2 to help keep the housing in the collapsed position.
Figure 7 shows a modification to the coffee bag 26 that includes a second eyelet 56 mounted to top of the perforated disc 36. A second elastic cord 58 extends downwardly from center of the member 42, which has the radial fingers 46, out through bottom 48 of the housing 30 and upwardly along side of the housing through the second eyelet 56. A pull tab 60 is attached to free end of the second elastic cord 58 so that -6- :
~.27~3~1 when a person pulls the pull tab 60 the second elastic cord 58 will pull down the member 42 to return it to bottom 48 o~ -the housing 30.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
