## Abstract

A container in accordance with an embodiment of the present disclosure includes a base with a core removably mounted in the base. The core includes a temperature controlling substance used to cool the contents of the container over a prolonged period of time. The core is removable from the base for placement in a freezer or other cold environment and then replaced to provide cooling to the material in the container.

## Claims

### Claim 1

A container system comprising:
a base; and
a core element removably mounted on the base;
the core element further comprising:
a lower bowl shaped shell;
a smaller, upper bowl shaped shell connected to the lower bowl shaped shell, such that a cavity is formed between the lower bowl shaped shell and the upper bowl shaped shell; and
a temperature controllin material provided in the cavity and configured to remain cool for a period of time and to cool material placed in the upper bowl shaped shell of the core element, the base further comprises:
an annular bottom;
a sidewall extending upward and inward from the bottom;
a top flange extending inward at a top of the sidewall, the top flange configured to support the removable core on an inner portion thereof.

### Claim 2 (depends on 1)

The container of claim 1, wherein the top flange further comprises a pair of recesses formed therein and positioned on opposite sides of the core element, the recesses configured to accommodate a user finger and to allow contact with the upper flange of the core element.

### Claim 3 (depends on 2)

The container of claim 2, wherein the sidewall includes at least one recess formed therein to provide a finger hold for a user to lift the container.

### Claim 4

A container system comprising:
a base; and
a core element removably mounted on the base;
the core element further comprising:
a lower bowl shaped shell;
a smaller, upper bowl shaped shell connected to the lower bowl shaped shell, such that a cavity is formed between the lower bowl shaped shell and the upper bowl shaped shell; and
a temperature controlling material provided in the cavity and configured to remain cool for a period of time and to cool material placed in the upper bowl shaped shell of the core element, the temperature controlling material is hydrated Cationic Polyacrylamide and grains of the hydrated Cationic Polyacrylamide are selected for positioning in the cavity such that they have a width that is substantially the same as that of the cavity.

### Claim 5 (depends on 4)

The container of claim 4, wherein the cavity has a width of substantially ¼ inch.

### Claim 6 (depends on 5)

The container of claim 5, wherein the grains of hydrated Cationic Polyacrylamide are positioned in the shell in a honey-comb like pattern.

### Claim 7 (depends on 5)

The container of claim 5, wherein selected grains of hydrated Cationic Polyacrylamide are colored and positioned in the cavity to form a desired pattern.
