Snap-fit Bottom Chime for Beverage Keg Assembly

The patent replaces the adhesive-based chemical bonding system with a mechanical snap-fit system. The bottom chime includes engagement elements (protrusions) that fit into corresponding recesses in the keg body, creating a mechanical interlock that secures the chime without requiring adhesives. This substitution eliminates the time-consuming adhesive application and curing processes while maintaining secure attachment through pure mechanical engagement.

The bottom chime is divided into functional segments: the main body portion and separate engagement elements (protrusions). These engagement elements can be integrated into the chime manufacturing process or added as separate components. The segmentation allows for modular assembly where the chime body is positioned on the keg base and then mechanically secured through the engagement elements fitting into the keg recesses, streamlining the assembly process.

The mechanical snap-fit connection separates the attachment function from permanent bonding. The engagement elements (protrusions) and corresponding recesses form a reversible mechanical interlock that can be easily separated by applying force in the opposite direction of engagement. This segmentation of the connection mechanism allows for simple disassembly without damaging either component, enabling easy recycling or reuse.

The design facilitates easy separation and recovery of components for recycling. The mechanical snap-fit connection allows the bottom chime to be detached from the keg body without degradation, enabling both components to be recovered and reused or recycled separately. This stands in contrast to adhesive bonding which creates permanent bonds that are difficult or impossible to reverse without damaging the parts.

The patent merges the top chime and bottom chime into a single integrated component. This unified chime structure provides both top and bottom protection in one piece, eliminating the need for separate top and bottom chime assemblies. The integrated design maintains structural integrity by creating a continuous protective element that spans both ends of the keg body, while significantly reducing the parts count and assembly complexity.

The single chime component serves multiple functions simultaneously: it provides structural protection for both the top and bottom portions of the keg, and incorporates engagement elements for mechanical attachment to the keg body. This multi-functionality consolidates what would traditionally require separate components (top chime, bottom chime, and potentially structural sleeves) into one universal element that performs all necessary protective and attachment functions.
