The chime may include a handle that has a waveform profile when viewed in cross-section along a length of the handle. The handle may include a first set of one or more regions of inflection that provide a first surface of the handle and a second set of one or more regions of inflection that provide an opposing second surface of the handle. The chime may be configured to be connected to a sleeve for surrounding at least part of a body portion of the keg. The interface between the chime and the sleeve may be configured to permit axially outward movement of the chime with respect to the sleeve in order to accommodate axial expansion of the keg. ## Claims ### Claim 1 A chime configured to be mounted to a keg, the chime comprising a handle that has a waveform profile when viewed in cross-section along a length direction of the handle, wherein the waveform profile defines at least one region of inflection forming at least part of a first surface of the handle, and at least one further region of inflection forming at least part of a second surface of the handle. ### Claim 2 (depends on 1) A chime according to claim 1, wherein the first surface is a bottom surface of the handle and the second surface is a top surface of the handle when the chime is in its normal orientation for use. ### Claim 3 (depends on 1) A chime according to claim 1, wherein at least one of the first and second surfaces of the handle is convexly curved when the handle is viewed in cross-section along its length direction. ### Claim 4 (depends on 1) A chime according to claim 1, wherein the waveform profile defines a plurality of regions of inflection that together form at least part of the first surface of the handle. ### Claim 5 (depends on 1) A chime according to claim 1, wherein the waveform profile defines a plurality of regions of inflection that together form at least part of the second surface of the handle. ### Claim 6 (depends on 1) A chime according to claim 1, wherein the handle comprises one or more walls forming a body of the handle. ### Claim 7 (depends on 6) A chime according to claim 6, wherein the handle comprises at least one connecting wall that extends between and connects a region of inflection forming at least part of the first surface of the handle and a region of inflection forming at least part of the second surface of the handle. ### Claim 8 (depends on 6) A chime according to claim 6, wherein the handle comprises at least one outer wall that extends outwardly from one of the regions of inflection to define an outer edge of the handle. ### Claim 9 (depends on 6) A chime according to claim 6, wherein the handle comprises at least one reinforcing web that extends between and connects an adjacent pair of the walls. ### Claim 10 (depends on 1) A chime according to claim 1, wherein at least one of the regions of inflection comprises a substantially planar central portion. ### Claim 11 (depends on 1) A chime according to claim 1, wherein at least one of the regions of inflection has a continuously curved shape. ### Claim 12 (depends on 1) A chime according to claim 1, wherein the waveform profile of the handle generally takes the form of a sine wave. ### Claim 13 (depends on 1) A chime according to claim 1, wherein the handle has a cross-sectional profile that is at least substantially constant along at least a majority of the length of the handle. ### Claim 14 (depends on 1) A chime according to claim 1, wherein the handle has a generally circular outer shape when viewed in cross-section along its length direction. ### Claim 15 (depends on 1) A chime according to claim 1, comprising at least one drainage aperture that is configured to allow fluid inside the handle to drain to the exterior of the handle. ### Claim 16 (depends on 1) A chime according to claim 1, wherein the handle extends between a pair of arms via which the handle is connected to a body portion of the chime. ### Claim 17 (depends on 1) A chime according to claim 1, wherein the handle has a curved shape along its length direction. ### Claim 18 (depends on 1) A chime according to claim 1, wherein the handle forms part of an outer crown portion of the chime. ### Claim 19 (depends on 1) A chime according to claim 1, wherein the chime is a top chime. ### Claim 20 (depends on 1) A keg assembly comprising a keg and at least one chime according to claim 1 mounted to the keg.
