Trash receptacle with trash bag dispenser system

Patent No. US8317055 (titled "Trash receptacle with trash bag dispenser system") on Apr 16, 2011. The application was issued on Nov 27, 2012.

What is this patent about?

’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.

How does this patent fit in bigger picture?

Technical Landscape

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.

Prosecution Position

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.

Claims

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.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Base
(Claim 1)
A base section supporting the container has an interior space in which a roll of trash bags is rotatably mounted. The base comprises a front wall, sidewalls, and an internal space, the front wall having a window opening providing access to the internal space. The bottom floor of the container leads into the internal space of the base.A support structure positioned underneath the main container floor that houses the roll of trash bags and includes a window for user access to the storage area.
Channel
(Claim 1)
A channel member with an open top and bottom extends inward into the container, enclosing the slotted opening within the container. The channel extends over substantially the full length of the through opening. Interconnected trash bags are configured to be pulled through the open bottom of the channel, through the channel, and out the open top of the channel.An internal guide structure within the container, defined by rear and lateral walls, that encloses the slotted opening and directs trash bags from the base to the top of the container.
Cover
(Claim 1)
A cover is positioned solely over the front wall and overlays the entire length of the through opening, thereby completely covering the through opening. The cover is removable in order to expose the entire length of the through opening. This allows the user to access the bags or the channel mechanism when necessary.A removable component that fits over the exterior of the front wall to conceal the slotted through opening along its entire length.
Holder rod
(Claim 1)
A holder rod is rotatably supported by rod tabs located within the sidewalls. This holder rod is configured to dispense a roll of interconnected trash bags. It allows for a quick and efficient replacement of a new roll of trash bags within the system.A rotatable axle supported by tabs within the base sidewalls designed to carry and dispense a roll of interconnected trash bags.
Slotted through opening
(Claim 1)
The front wall of the container has a slotted opening which extends from the bottom floor upwards along substantially the entire length of the front wall. This opening extends from the internal surface to the external surface, completely through and along the front wall. It allows a trash bag to be threaded from the interior space of the base and through the container.A vertical aperture that penetrates completely through the front wall of the trash container, extending from the bottom floor upwards across at least half the wall's length to facilitate bag threading and access.
