1. Verified U.S. design patent references

The company knowledge base contains verified records for selected silicone travel bottle and dispenser-container designs. The website lists these references so buyers can identify the record being discussed rather than relying on a broad patent claim.

  • US D1,050,810 S — silicone travel bottle; application 29/911,472; granted November 12, 2024
  • US D1,053,668 S — silicone travel bottle; application 29/925,523
  • US D1,054,861 S — dispenser container; application 29/836,298

2. What the references do not claim

The records do not establish that every Zhongding product is patented, that all jurisdictions provide the same protection or that any third-party product infringes. Patent validity, ownership changes and infringement questions require legal review of the current official record.

  • No site-wide claim that all products are patented
  • No infringement opinion
  • No automatic extension to unrelated designs
  • No substitute for jurisdiction-specific legal advice

3. Material and test documentation

The company archive contains files relating to silicone, PP, ABS and selected product categories. A file should be checked for applicant or report holder, sample description, issue date, test method and result scope before it is used for a buyer project.

Where a buyer needs a specific market document, Zhongding should confirm whether an existing record is suitable or whether project-specific testing is required.

4. Company and document attribution

Company: Dongguan Zhongding Technology Co., Ltd. Documents must still be cited under the exact entity name shown on the original record.

5. Document-request checklist

Include the product, material, destination market and buyer review purpose when requesting files. This allows the response to be narrower and more reliable.

  • Product or SKU under review
  • Material or component
  • Destination market
  • Required standard or buyer checklist
  • Purpose: qualification, quotation, pre-shipment or listing
  • Required language and due date

FAQ

Frequently asked questions

Are the patent numbers on this site verified?

The three listed U.S. design patent references were checked against records retained in the company knowledge base. Current legal status should still be confirmed in the relevant official database for legal decisions.

Can a buyer request the underlying documents?

Buyers can request relevant patent, material or test files for project review. Availability and applicability depend on the product and document scope.

Why are two company names shown?

The company has confirmed they are two entity names used by the same operating company. Each original document remains attributed to the entity name printed on that record.
