Abstract
Abstract A cooling and insulating holder for a container such as a beverage can or the like has a plurality of hollow arcuate reservoir pieces which fit together to form a ring with a receiving opening therein to receive the container. A resilient sleeve surrounds the reservoir pieces and holds them in ring configuration. In this way, a container larger than the normal opening in the ring may be inserted into the opening and the reservoir pieces will separate against the force of the resilient sleeve. If the opening in the ring is equal to or slightly less in diameter than the smallest diameter container expected to be used with the device, the device will maintain that and larger containers snugly within the ring with good contact between the container and the inner reservoir walls. The reservoir pieces are each filled with a coolant material which, in use, is frozen prior to insertion of the container to be cooled. The coolant then absorbs heat from a container and its contents placed in the opening as the coolant melts and warms.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
145 words
A cooling and insulating device for containers such as beverage cans and the like, comprising a plurality of hollow, arcuate reservoir pieces, the number of pieces being such that when placed together in abutting, side-by-side relationship they form a ring with an opening therethrough forming open ends of the ring; coolant material within each of said reservoir pieces; and resilient means surrounding at least a portion of said reservoir pieces when placed together to form a ring for biasing said reservoir pieces inwardly thereby maintaining said reservoir pieces in ring formation and allowing said reservoir pieces to separate against the bias of the resilient means and snugly receive a container larger than the opening, said resilient means providing a surface for holding said device in the hand of a user and also extending across an open end of the ring to form a bottom therefor.
Claim 2
Dependent Claim
145 words

Claim 3
Dependent Claim
21 words
A cooling and insulating device according to claim 1, wherein the resilient means is a resilient sleeve surrounding the reservoir pieces.
Claim 4
Dependent Claim
20 words
A cooling and insulating device according to claim 2, wherein the resilient sleeve is removable from about the reservoir pieces.
Claim 5
Dependent Claim
15 words
A cooling and insulating device according to claim 3, wherein there are two reservoir pieces.
Claim 6
Dependent Claim
55 words
A cooling and insulating device according to claim 4, wherein the opening in the ring is sized to snugly receive a beverage can having the minimum outside diameter of commonly available beverage cans, thereby requiring the reservoir pieces to separate from each other upon receipt of a can of larger than the minimum outside diameter.
Claim 7
Dependent Claim
35 words
A cooling and insulating device according to claim 5, wherein the top edges of the reservoir pieces are rounded to facilitate entry of a can having a diameter larger than the opening in the ring.
Claim 8
Dependent Claim
42 words
A cooling and insulating device according to claim 6, wherein the height of the reservoir pieces are less than the height of the container to be cooled by an amount sufficient to allow a user to drink from the container being cooled.
Claim 9
Dependent Claim
21 words
A cooling and insulating device according to claim 7, wherein the resilient sleeve surrounds the outside surfaces of the reservoir pieces.
Claim 10
Dependent Claim
24 words
A cooling and insulating device according to claim 8, wherein the coolant in the reservoir pieces is frozen prior to use of the device.
Claim 11
Dependent Claim
24 words
A cooling and insulating device according to claim 9, wherein the coolant material is an aqueous solution including about 14% starch and 1% borax.
Claim 12
Dependent Claim
33 words
A cooling and insulating device according to claim 2, wherein the resilient sleeve has an interior surface of low coefficient of friction to facilitate easy insertion of the reservoir pieces into the sleeve.
Claim 13
Dependent Claim
21 words
A cooling and insulating device according to claim 11, wherein the resilient sleeve is made of a fabric backed neoprene rubber.
Claim 14
Dependent Claim
15 words
A cooling and insulating device according to claim 1, wherein there are two reservoir pieces.
Claim 15
Dependent Claim
57 words
A cooling and insulating device according to claim 1, wherein the opening in the ring is sized to snugly receive a container having the minimum outside diameter of containers expected to be used with said device, thereby requiring the reservoir pieces to separate from each other upon receipt of a container larger than the minimum outside diameter.
Claim 16
Dependent Claim
35 words
A cooling and insulating device according to claim 14, wherein the top edges of the reservoir pieces are rounded to facilitate entry of a container having a diameter larger than the opening in the ring.
