BACKGKO _ QF 5~y~ TION
This instant invention relates generally to packets for
brewing coffee and more specifically it relates to a coffee
bag.
Numerous packets for brewing coffee have been provided
in prior art that are adapted to hold an individual portion of
ground coffee for insertion into a cup for making one serving
o~ brewed coffee. For example, U.S. patents numbered
2,157,656; 2,786,761 and 3,640,727 all are illustrative of
such prior art. While these units may be suitable for the
particular purpose to which they address, they would not be as
suitable for the purposes of the present invention as
heretofore described.

SUMMARY OF TI~E INVENTION
A primary object of the present invention is to provide
a coffee bag that will overcome the shortcomings oE the prior
art devices.
Another object is to provide a coffee bag for holding a
portion of very fine ground coffee for making an individual
cup of coffee when hot wa~er is pourecl into the cup.
An additional object is to provide a coffee bag that is
expandable when inserted within hot water and contains a
ground coffee agitating device built into the coffee bag.
A further object is to`provide a coffee bag that is
simple and easy to use.
A still further object is to provide a coffee bag that
is economical in cost to manufacture.
Further objects of the invention will appear as the
description proceeds.
To tbe accomplishment of the above and related objects,
this invention may be embodied in the form illustrated in the
accompanying drawings, attention being called to the fact,
~0 however, that the drawings are illustrative only, and that
changes may be made in the specific construction illustrated
and described within the scope of the appended claims.

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.
