Using a twisting motion, the containers including the wires are collapsed. The collapsing, twisting motion is produced though the use of wires that are displaced in a plurality of locations along the circumference of the container. The wires include horizontal sections that are configured to be retained in the base or rim of the container in a manner that permits them to rotate to transition the container between expanded and collapsed positions. ## Claims ### Claim 1 A set of collapsible twist-fold containers comprising: an upper container; a lower container; and a plurality of wires attaching the upper container to the lower container, the plurality of wires each having a first generally horizontal portion and a second generally horizontal portion, the first generally horizontal portion being pivotally received within a separate one of a plurality of upper channels carried on a rim of the upper container, and the second generally horizontal portion being pivotally received within a separate one of a plurality of lower channels carried on a rim of the lower container; wherein the upper container is supported above the lower container by the plurality of wires such that a central axis extends through the center of the upper container and the lower container; whereby the set of containers is selectively positionable between an expanded position in which the upper container is positioned distant from the lower container and supported by the plurality of wires, and a collapsed position in which the upper container is rotated about the central axis and positioned relatively closer to the lower container and nested within the lower container, each of the plurality of wires being rotatably movable within each of the first plurality of channels and the second plurality of channels to transition the set of containers between the expanded position and the collapsed position, the plurality of wires remaining within the plurality of channels in the expanded position, the collapsed position, and the transition between the expanded position and the collapsed position. ### Claim 2 (depends on 1) The collapsible twist-fold containers of claim 1, wherein each of the first generally horizontal portions includes a first retention member configured to hold the first generally horizontal portion of the plurality of wires within the plurality of upper channels. ### Claim 3 (depends on 2) The collapsible twist-fold containers of claim 2, wherein each of the second generally horizontal portions includes a second retention member configured to hold the second generally horizontal portion of the plurality of wires within the plurality of lower channels. ### Claim 4 (depends on 1) The collapsible twist-fold containers of claim 1, further comprising a middle container, each of the plurality of wires further supporting the middle container between the upper container and the lower container, the plurality of wires each further having a central generally horizontal portion, the central generally horizontal portion being pivotally received within a separate one of a plurality of middle channels carried on a rim of the middle container. ### Claim 5 (depends on 1) The collapsible twist-fold containers of claim 1, wherein said first container is sized to receive said second container in a nesting fashion. ### Claim 6 (depends on 1) The collapsible twist-fold containers of claim 1, further comprising a means for retaining the containers in a collapsed position. ### Claim 7 (depends on 6) The collapsible twist-fold containers of claim 6, wherein the means for retaining the containers in a collapsed position includes at least one magnet secured to a base of at least one of the upper container or the lower container. ### Claim 8 (depends on 1) The collapsible twist-fold containers of claim 1, wherein the in the collapsed position the upper container nests within the lower container, with the rim of the upper container being below the rim of the lower container. ### Claim 9 (depends on 1) The collapsible twist-fold containers of claim 1, wherein the upper container is formed as a bowl. ### Claim 10 A set of collapsible twist-fold containers comprising: an upper container; a lower container, the upper container being smaller than the lower container; and a plurality of wires supporting the upper container above the lower container such that a central axis extends through the center of the upper container and the lower container, the plurality of wires each having a first generally horizontal portion and a second generally horizontal portion, the first generally horizontal portion being pivotally received within a separate one of a plurality of upper channels carried in the upper container, and the second generally horizontal portion being pivotally received within a separate one of a plurality of lower channels carried on the lower container; the set of containers being selectively positionable between an expanded position in which the upper container is positioned distant from the lower container and supported by the plurality of wires, and a collapsed position in which the upper container is positioned relatively closer to the second container and the plurality of wires are in a spiral configuration between the upper container and the lower container, each of the plurality of wires being rotatably movable within each of the first plurality of channels and the second plurality of channels to transition the set of containers between the expanded position and the collapsed position, the plurality of wires remaining within the plurality of channels in the expanded position, the collapsed position, and the transition between the expanded position and the collapsed position. ### Claim 11 (depends on 10) The collapsible twist-fold containers of claim 10, further comprising a middle container, each of the plurality of wires further supporting the middle container between the upper container and the lower container, the plurality of wires each further having a central generally horizontal portion, the central generally horizontal portion being pivotally received within a separate one of a plurality of middle channels carried on the middle container. ### Claim 12 (depends on 10) The collapsible twist-fold containers of claim 10, further comprising a magnet positioned on at least one of the upper container or the lower container for retaining the containers in a collapsed position. ### Claim 13 (depends on 10) The collapsible twist-fold containers of claim 10, wherein the upper container is formed as a bowl. ### Claim 14 A set of collapsible twist-fold containers comprising: an upper container;
