Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 335 words
A disposable infusion stirring and hanging device for preparing a beverage comprising: a porous flexible bag made of a liquid permeable material, an infusable substance contained in said bag and a thin, flat premolded rigid nontoxic element; said bag comprising side edges and a top and bottom edge; said element comprising a lower section located within and enveloped by the porous bag and an integral upper section protruding vertically out of the bag; said lower section comprising a thin bar extending longitudinally within the bag along one of said side edges approximately from the top of the bag to approximately the bottom of the bag with two thin protrusions extending transverse to said bar and either at least partially across the bag or around the perimeter of said bag to form either a partial frame or full frame, respectively, within the bag sufficient to impart rigidity to said bag; said upper section including a first portion that is a continuation of said thin bar and extending longitudinally from said thin bar and protruding out of the bag along approximately said one side edge, said upper section further including an enlarged portion extending transverse from said longitudinally oriented first portion, and beyond the plane extending normal from said one side edge, said enlarged portion including a longitudinally oriented groove in said enlarged portion that is positioned beyond the plane extending normal from said one side edge, said groove being of a size sufficient to fit on the rim of a cup or glass, said enlarged portion further including an aperture of a size sufficient to allow one to press the thumb against the forefinger through the aperture and employ said rigid element as a stirrer, said length of the element from said enlarged portion to the bottom of said lower section being of a size such that when said groove is fitted onto a rim of said cup or glass said bag hangs on the wall and floats in the liquid in said cup or glass.
Claim 2
Dependent Claim 335 words
A disposable infusion stirring and hanging device for preparing a beverage comprising: a porous flexible bag made of a liquid permeable material, an infusable substance contained in said bag and a thin, flat premolded rigid nontoxic element; said bag comprising side edges and a top and bottom edge; said element comprising a lower section located within and enveloped by the porous bag and an integral upper section protruding vertically out of the bag; said lower section comprising a thin bar extending longitudinally within the bag along one of said side edges approximately from the top of the bag to approximately the bottom of the bag with two thin protrusions extending transverse to said bar and either at least partially across the bag or around the perimeter of said bag to form either a partial frame or full frame, respectively, within the bag sufficient to impart rigidity to said bag; said upper section including a first portion that is a continuation of said thin bar and extending longitudinally from said thin bar and protruding out of the bag along approximately said one side edge, said upper section further including an enlarged portion extending transverse from said longitudinally oriented first portion, and beyond the plane extending normal from said one side edge, said enlarged portion including a longitudinally oriented groove in said enlarged portion that is positioned beyond the plane extending normal from said one side edge, said groove being of a size sufficient to fit on the rim of a cup or glass, said enlarged portion further including an aperture of a size sufficient to allow one to press the thumb against the forefinger through the aperture and employ said rigid element as a stirrer, said length of the element from said enlarged portion to the bottom of said lower section being of a size such that when said groove is fitted onto a rim of said cup or glass said bag hangs on the wall and floats in the liquid in said cup or glass.
Claim 3
Dependent Claim 37 words
A disposable infusion, stirring and hanging device for preparing a beverage according to claim 1 wherein the lower section located within the porous bag extends along at least three quarters of the length of said porous bag.
Claim 4
Dependent Claim 33 words
A disposable infusion, stirring and hanging device for preparing a beverage according to claim 1 wherein the edges of the liquid permeable material forming the porous bag are sealed to the lower section.
Claim 5
Dependent Claim 23 words
A disposable infusion, stirring and hanging device according to claim 1 wherein the premolded rigid nontoxic element is made of a plastic material.
Claim 6
Dependent Claim 30 words
A sequence of two or more disposable infusion, stirring and hanging devices according to claim 1 wherein each device is attached one to the other by an easily detachable attachment.
Claim 7
Dependent Claim 28 words
A sequence according to claim 5 wherein the disposable infusion, stirring and hanging devices are attached one to the other at the upper ends of the enlarged portion.
