Trash can assembly

What is this patent about?

’997 is related to the field of refuse containers, specifically focusing on modular trash can assemblies that utilize specialized hinge and trim components. The background context involves the need for receptacles that are easy to ship, assemble, and maintain, while providing aesthetic features like hidden bag liners and controlled lid movement to prevent damage to surrounding walls.

The underlying idea behind ’997 is a modular hinge architecture that allows a complete lid and trim ring assembly to be snapped onto or removed from a container body without tools. By utilizing a spring-loaded, translating pin mechanism within the hinge unit, the invention enables the lid assembly to be securely docked into a dedicated connection base on the body, facilitating both efficient nesting for transport and easy replacement of parts by the end user.

The claims of ’997 focus on a trash can assembly featuring a body with a rear-mounted connection base and a detachable lid assembly. Independent claim 1 specifically protects the use of a movable connection member—such as a biased pin—that retracts to allow the hinge unit to enter a receiving area on the body and extends to lock the two components together. Independent claim 15 further covers the functional integration of a lid and a trim ring that rotate independently, both of which are coupled to a dampening mechanism to regulate their closing speed.

In practice, the invention works by allowing a user to retract the hinge pins via integrated handles, aligning the lid assembly with the body's connection base, and releasing the pins to engage the mounting holes. This creates a stable pivot point for both the lid and the trim ring. Unlike prior approaches where hinges are permanently riveted or require complex tools for assembly, this design uses the cam-action of the pins against angled guides to simplify the attachment process while maintaining a high-strength metal-on-metal connection at the primary stress points.

The system differentiates itself by decoupling the aesthetic trim ring from the functional lid, allowing the ring to be lifted independently to secure a trash bag liner. By incorporating a dual-damped system, the invention ensures that neither the lid nor the heavy trim ring slams shut, protecting the container's structural integrity. Additionally, the inclusion of a deployable spacer ensures the entire assembly maintains a safe distance from walls, preventing the rear-projecting hinge from causing surface scuffs or noise during operation.
