Interlocking containers

Claim 2

An interlocking container comprising: a central body portion in the shape of a right rectangular prism having first and second opposing sides disposed in parallel to each other; a first arm extending outwardly from said first side of said central body; a second arm extending outwardly from said second side of said central body; a first arm comprising a shaped protrusion extending upwardly from one surface thereof; said second arm comprising a shaped depression in one surface thereof; said protrusion and depression being matched for interlocking engagement; whereby a first one of said containers can be interlocked with at least a second one of said containers.

Claim 3

An interlocking container as defined in claim 1 wherein the rear surfaces of said arms being continuous with the rear surface of said central body;

Claim 4

the thickness of said first arm being substantially one third the thickness of said central body; the height of said protrusion being substantially one third the thickness of said central body; the thickness of said second arm being substantially two thirds the thickness of said central body; and the depth of said depression being substantially one third the thickness of said central body; whereby, when a plurality of said containers are interlocked to form an interlocking arrangement, the front and rear surfaces respectively of the arrangement are continuous.

Claim 5

the thickness of said first arm being substantially one third the thickness of said central body; the height of said protrusion being substantially one third the thickness of said central body; the thickness of said second arm being substantially two thirds the thickness of said central body; and the depth of said depression being substantially one third the thickness of said central body; whereby, when a plurality of said containers are interlocked to form an interlocking arrangement, the front and rear surfaces respectively of the arrangement are continuous.

Claim 6

An interlocking container as defined in claim 2 wherein said protrusion comprises a pair of first tongues, each one of said tongues being spaced from said central body by respective ones of a pair of first grooves disposed adjacent the one side of said central body, the width of said first grooves being equal to the width of said first tongues; and wherein said depression comprises a pair of second grooves disposed on said second arm adjacent the second side of said central body, said second arm further comprising a pair of second tongues, each of said tongues being spaced from said second side of said central body by the respective ones of said second grooves, the width of said second tongues being equal to the width of said second grooves; the width of said first tongues being equal to the width of said second grooves.

Claim 7

An interlocking container as defined in claim 1 wherein the width of said first arm is equal to the width of said second arm.

Claim 8

An interlocking container as defined in claim 1 wherein the length of each aid arm is equal to the length of said central body.

Claim 9

An interlocking container for reusable ice pack substitutes comprising: a substantially rectangular central body; a first substantially rectangular arm, equal in length to the length of said body, and equal in thickness to one third the thickness of said body, extending from one side of said cubical body; a protrusion extending upwardly from a surface of said first arm, the height of said protrusion being one third the thickness of said central body; a second substantially rectangular arm, equal in length to the length of the central body, and equal in thickness to two thirds of the thickness of the central body extending from an opposing side of said central body; a depression in a surface of said second arm having a depth equal to one third the thickness of said central body; the widths of said arms being equal to each other; said protrusion and depression being matched for interlocking engagement; whereby a first one of said containers can be interlocked with at least a second one of said containers.

Claim 10

An interlocking container for reusable ice pack substitutes comprising: a substantially rectangular central body; a first substantially rectangular arm, equal in length to the length of said body, and equal in thickness to one third the thickness of said body, extending from one side of said cubical body; a protrusion extending upwardly from a surface of said first arm, the height of said protrusion being one third the thickness of said central body; a second substantially rectangular arm, equal in length to the length of the central body, and equal in thickness to two thirds of the thickness of the central body extending from an opposing side of said central body; a depression in a surface of said second arm having a depth equal to one third the thickness of said central body; the widths of said arms being equal to each other; said protrusion and depression being matched for interlocking engagement; whereby a first one of said containers can be interlocked with at least a second one of said containers.

Claim 11

A container as defined in claim 6 wherein the rear surfaces of said arms are continuous with the rear surface of said central body.

Claim 12

A container as defined in claim 6 wherein; the rear surfaces of said arms being continuous with the rear surface of said central body; the thickness of said first arm being substantially one third the thickness of said central body; the height of said protrusion being substantially one third the thickness of said central body; the thickness of said second arm being substantially two thirds the thickness of said central body; and the depth of said depression being substantially one third the thickness of said central body; whereby, when a plurality of said containers are interlocked to form an interlocking arrangement, the front and rear surfaces respectively of said containers are continuous.
