What the claims cover, in plain language
Claim 1 - a luggage storage box with a lid that opens to expose a storage cavity. The cavity is recessed into one side of the case shell or formed by a separate base. The lid has a lower hinge seat so it swings open and closed, and a lock that locks it to the base.
Claims 2-5 add: the base fits into an opening in the shell; a USB cable runs through the cavity to the case lock’s USB port; two stoppers on the lid form a holder for items; a mesh pouch inside the cavity.
Claims 6-8 cover a trolley case using this box: the cavity sits between the telescoping handle rails, the USB port is built into a zipper lock at the bottom of the case, the case has foot pads, and the cavity may be round, oval or polygonal.
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.
What this means for production
This patent was filed only in China, and it lapsed in 2024 because annual fees were not paid. It no longer restricts anyone - in China or elsewhere - and no US or other foreign family member is listed.
Before production, keep in mind:
- Other patents may exist. This patent is cited by later US luggage patents from other companies, which protect their own latch, strap and luggage-system designs. Your final design should not copy those features. A freedom-to-operate (FTO) search by a US patent attorney is recommended before volume production.
- Design patents. The overall look of a suitcase can be protected by design patents; give your case its own styling.

Things to plan for (US market)
- Airline sizes - carry-on dimensions should fit common US airline limits.
- TSA-accepted locks - for the main zipper lock, so TSA can open the case without damage.
- Power banks - airlines require lithium power banks in carry-on bags, not checked luggage; the product should be sold without a built-in battery, with a clear note in the listing.
How a project runs
- Inquiry - sizes, materials, features and target quantity.
- Design - compartment size and position, lid and lock, USB routing.
- Prototype - samples built on an existing shell to test fit and opening.
- Tooling & pilot run - shell and compartment molds, small batch, drop and wheel tests.
- Production - volume production, packing and shipping.
Quantities & timeline
Hard-shell luggage needs shell molds; adapting an existing shell design to take the compartment insert usually costs less than tooling a completely new shell. Tell us your sizes, quantity and target price and we will reply with options.
