Trash can system with a folded bag dispensing supply

What is this patent about?

’378 is related to the field of waste management hardware and, more specifically, to integrated dispensing systems for trash can liners. The background context involves the common inconvenience of manually replacing trash bags, where traditional roll-based dispensers often suffer from high friction and mechanical resistance. The invention seeks to streamline the replenishment process by housing a supply of liners directly within the receptacle, ensuring that a fresh bag is immediately accessible once a full one is removed.

The underlying idea behind ’378 is to replace the high-torque requirement of rotating a heavy roll of bags with a low-friction interfolded dispensing mechanism. By utilizing folded or interfolded bags—similar to how tissues are pulled from a box—the system allows a user to extract a new liner with minimal force. This insight recognizes that the trailing edge of a departing bag can naturally draw up the leading edge of the next bag, provided the supply is managed by a structure that stabilizes the stack against the upward pulling force.

The claims of ’378 focus on a multi-component modular housing assembly designed to be secured to the interior floor of a trash can. The primary independent claim describes a rectangular box base, a removable lid featuring a specific dispensing aperture, and a unique two-tiered plate that acts as the bag carrier. This plate is engineered with an upper tier that slides into a set of rails and a backstop on the underside of the lid, while the lower tier provides a dedicated surface for affixing the bag supply.

In practice, the invention functions as a specialized cartridge system. The two-tiered plate serves as a bridge between the bulk supply of bags and the dispensing lid, allowing the entire bag stack to be swapped out easily by sliding the plate in or out of the rail-and-backstop mechanism. This configuration ensures that the bags remain centered under the lid's opening, preventing the supply from shifting or jamming during the extraction process. The use of a rigid box and lid assembly protects the unused bags from being crushed or soiled by the active liner above it.

This approach differs from prior solutions by moving away from universal roll dispensers that rely on axle rotation or hook-and-loop fasteners. Instead, it employs a mechanical slide-in architecture that provides a stable, stationary platform for folded bags. By integrating the support rails directly into the lid and utilizing a tiered plate to hold the bags, the system minimizes the vertical profile of the dispenser. This maximizes the usable volume of the trash can while ensuring that the force of removing a full bag is distributed across a reinforced, anchored structure.
