Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 187 words
A heat insulating vessel for holding a cylindrical drink container, said vessel tightly fitting around a portion of the cylindrical wall of the container, said vessel having a body integrally formed of a cylindrical wall portion and a bottom portion, the body being formed from a microcellularly foamed plastic, at least one horizontal finger groove means for receiving substantially the entire palm side of a user's finger, said finger groove means being formed in the wall portion and extending circumferentially completely around said wall portion, parallel to said bottom portion, wherein the upper edge of said cylindrical wall portion is inclined with respect to the bottom portion, said inclined upper edge having an elliptical shape and wherein when said finger groove means is depressed by the fingers of a user holding said vessel, said elliptical shape forms a circular shape having a diameter larger than the diameter of said bottom portion of said body thereby facilitating the placement of a container in said vessel, and wherein when said finger groove means is not depressed, the entire said inclined upper edge contacts the container inserted in said vessel.
Claim 2
Dependent Claim 187 words
A heat insulating vessel for holding a cylindrical drink container, said vessel tightly fitting around a portion of the cylindrical wall of the container, said vessel having a body integrally formed of a cylindrical wall portion and a bottom portion, the body being formed from a microcellularly foamed plastic, at least one horizontal finger groove means for receiving substantially the entire palm side of a user's finger, said finger groove means being formed in the wall portion and extending circumferentially completely around said wall portion, parallel to said bottom portion, wherein the upper edge of said cylindrical wall portion is inclined with respect to the bottom portion, said inclined upper edge having an elliptical shape and wherein when said finger groove means is depressed by the fingers of a user holding said vessel, said elliptical shape forms a circular shape having a diameter larger than the diameter of said bottom portion of said body thereby facilitating the placement of a container in said vessel, and wherein when said finger groove means is not depressed, the entire said inclined upper edge contacts the container inserted in said vessel.
Claim 3
Dependent Claim 27 words
A heat insulating vessel of claim 1 wherein the portion of the upper edge of the cylindrical wall is uniformly inclined with respect to the bottom portion.
Claim 4
Dependent Claim 28 words
A heat insulating vessel of claim 1 wherein the portion of the upper edge of the cylindrical wall forms an inclined curve with respect to said bottom portion.
Claim 5
Dependent Claim 29 words
A heat insulating vessel of claim 1 wherein the vessel is made of a microcellularly foamed core and non-foamed skin structure with a gross gravity of less than 0.1.
Claim 6
Dependent Claim 22 words
A heat insulating vessel of claim 4 wherein the microcellularly foamed core and non-foamed skin structure is molded by two-part soft polyurethane.
