Patent No. US8317055 (titled "Trash receptacle with trash bag dispenser system") on Apr 16, 2011. The application was issued on Nov 27, 2012.
’055 is related to the field of waste management hardware, specifically focusing on integrated storage and dispensing systems for disposable liners. The background context involves the common inconvenience and lack of hygiene associated with storing replacement trash bags at the bottom of a bin or in a separate location, which often requires the user to reach into a soiled container or search for a new roll when a bag is full.
The underlying idea behind ’055 is to integrate a dedicated vertical guide channel directly into the interior wall of the receptacle, linking a bottom-mounted storage magazine to the top rim of the bin. By routing a continuous roll of bags through this internal conduit, the system ensures that the next available liner is always staged at the top of the container, isolated from the actual refuse, and ready for immediate deployment without requiring the user to reach into the collection area.
The claims of ’055 focus on a specific architecture comprising a container with a slotted through opening that runs at least half the length of the front wall, paired with an internal channel that encloses this slot. The assembly includes a base section housing a rotatable holder rod for the bag roll and a removable cover that spans the entire length of the exterior slot, allowing a user to access the bag path for initial threading while maintaining a sealed appearance during normal use.
In practice, the invention functions as a continuous feed system where the act of removing a full bag does not leave the user searching for a replacement. A roll is loaded into the base via a front access window, and the lead bag is threaded up through the floor and into the protective channel. Because the channel extends inwardly from the front wall, it creates a physical barrier that prevents liquid or solid waste from contaminating the clean bags waiting in the queue.
This design differs from prior art by utilizing a full-length access slot and a corresponding exterior cover, which simplifies the traditionally difficult task of threading a new roll through a narrow internal passage. By combining a bottom-loading magazine with a top-exit guide, the system eliminates the need for complex mechanical dispensers while ensuring that the perforation for the next bag is always positioned at a convenient, sanitary height for the user.
In the early 2010s when ’055 was filed, waste management hardware for residential and commercial environments was typically implemented using standalone receptacles that relied on external storage for liner consumables. At a time when systems commonly relied on manual retrieval of perforated liners from secondary packaging or loose storage at the base of the bin, the integration of dispensing mechanisms was often constrained by mechanical complexity or sanitary concerns. Hardware designs during this era frequently prioritized simple volumetric capacity, making the inclusion of internal guiding structures or integrated roll-mounting assemblies non-trivial due to the need to balance structural integrity with the spatial requirements of standard liner rolls.
The disclosed invention achieves a technical advancement through an architectural shift that integrates a dedicated dispensing channel directly into the vertical wall of a trash receptacle. By utilizing a base section that rotatably mounts a roll of liners beneath the container floor and threading the material through a specific channel member that encloses a slotted opening, the system overcomes the technical constraint of unsanitary liner retrieval. This structural solution enables a continuous feed mechanism where the separation of a single liner at the top of the channel automatically positions the subsequent liner for immediate access. The integration of these components reduces mechanical complexity while ensuring that the storage and guiding functions do not interfere with the primary waste-holding volume of the container.
The patent contains a total of 2 claims, with claim 1 serving as the sole independent claim. This independent claim focuses on a trash receptacle integrated with a bag dispenser system, specifically detailing a container with a slotted front wall, a base housing a rotatable bag roll holder, and a vertical channel that guides bags from the base through the container wall to a removable cover. The single dependent claim serves to further define the structural relationship between the internal channel and the slotted opening in the container wall.
