Rolling Tote Bag

Patent No. US12053071 (titled "Rolling Tote Bag") was filed by Codefine International Sa on Jan 22, 2024.

What is this patent about?

’071 is related to the field of rolling tote bags, specifically those designed for shopping, groceries, or laundry. Existing rolling tote bags often suffer from limitations such as sagging bottom corners, potential for dust and debris to enter the storage volume through wheel apertures, and complex or unreliable attachment mechanisms for the rolling support assembly. These shortcomings can lead to wear and tear, hygiene issues, and potential separation of the bag from its rolling base.

The underlying idea behind ’071 is to provide a more robust and practical rolling tote bag by securing the rolling support assembly externally , underneath the bag's bottom panel, rather than inside the storage volume. This is achieved using a retaining structure made of fabric panels that securely hold the support plate and caster wheels against the underside of the bag. This external mounting eliminates the need for wheel apertures in the bottom panel, preventing dust ingress and structural weaknesses.

The claims of ’071 focus on a rolling tote bag with a collapsible fabric container and a rolling support assembly. The key feature is a retaining structure beneath the bottom panel that holds the support plate externally. This structure can take different forms, including overlapping releasable flaps with fastening elements (e.g., hook-and-loop fasteners) or a retaining envelope secured by a zipper. The claims also cover specific features like gusset folds for compact folding and bubble wrap reinforcement in the side panels.

In practice, the rolling support assembly, consisting of a support plate and caster wheels, is attached to the underside of the tote bag using the retaining structure. For example, multiple flaps, strategically positioned around the bottom panel, wrap around the support plate and are secured using hook-and-loop fasteners. This creates a secure and easily detachable connection. The flaps may have apertures or be spaced to accommodate the caster wheels, ensuring smooth rolling.

This design differentiates itself from prior art by avoiding internal mounting of the rolling support, which requires apertures in the bag's bottom and reduces storage space. Unlike some prior solutions, the retaining structure provides support across the entire bottom surface, preventing sagging. The use of releasable flaps or a zippered envelope allows for easy removal and replacement of the rolling support, while ensuring a secure connection during use, addressing the limitations of snap fastener-based systems.

How does this patent fit in bigger picture?

Technical landscape at the time

In the early 2020s when ’071 was filed, rolling tote bags were commonly constructed with collapsible container bodies and removable rolling support assemblies, at a time when attaching the support assembly to the container body often involved fasteners or internal securing flaps. When hardware or software constraints made robust and cost-effective attachment mechanisms non-trivial, designs often compromised between ease of use, structural integrity, and manufacturing costs.

Novelty and Inventive Step

Claims were amended during prosecution. Claims 1, 5-12, and 15 were rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA) as being indefinite. Claims 13, 14, and 16-24 were allowed, and claims 2-4 were canceled. The Office action was made final. The prosecution record does describe the technical reasoning and specific claim changes that led to allowance.

Claims

This patent contains 21 claims, with independent claims 1, 10, 13, and 14. The independent claims are directed to a rolling tote bag with a collapsible container body and a rolling support assembly, focusing on different retaining structures for the support plate and folding configurations. The dependent claims generally add specific details and features to the rolling tote bag described in the independent claims.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Collapsible container body
(Claim 1, Claim 10, Claim 13, Claim 14)
“The rolling tote bag comprising a collapsible container body made of a foldable assembly of fabric panels, including a bottom panel and side panels, that jointly define an inner storage volume when in an expanded state.”A bag-like structure formed from fabric panels that can be folded or collapsed for storage when not in use, and expanded to create an inner storage volume when in use.
Gusset fold
(Claim 13)
“Opposite short side panels of the collapsible container body are each provided with a gusset fold designed to allow outward folding of the opposite short side panels into flat-folded gusset sections.”A fold in the short side panels of the collapsible container body that allows them to be folded outward into flat-folded gusset sections, enabling the bag to be flattened.
Releasable securing flaps
(Claim 1)
“By way of preference, the retaining structure includes first and second releasable securing flaps attached to and positioned along opposite lateral ends of the bottom panel, which first and second releasable securing flaps are partially overlapping and releasably attachable to one another to encase the support plate between the bottom panel and the first and second releasable securing flaps.”Fabric panels attached to the bottom panel that can be fastened and unfastened to secure the support plate.
Retaining structure
(Claim 1, Claim 10, Claim 13, Claim 14)
“According to the invention, the collapsible container body further comprises a retaining structure formed of one or more fabric panels, which retaining structure is provided underneath the bottom panel and is configured to securely hold the support plate outside of the inner storage volume against an underside of the bottom panel.”A structure formed of one or more fabric panels, located underneath the bottom panel of the collapsible container body, and configured to hold the support plate against the underside of the bottom panel, outside of the inner storage volume.
Rolling support assembly
(Claim 1, Claim 10, Claim 13, Claim 14)
“The rolling tote bag further comprises a rolling support assembly to provide rolling support for the collapsible container body in the expanded state, the rolling support assembly including a support plate and a plurality of caster wheels provided on an underside of the support plate.”A structure including a support plate and caster wheels, designed to be attached to the collapsible container body to provide rolling support.
