What the claims cover, in plain language

Claim 1 defines a fishing cap comprising a body with a crown and visor. The crown uses dual-layer fabric (breathable outer, sweat-absorbing inner). The visor has heat-insulating fabric wrapping an elastic support plate. An annular magnetic strip is embedded in the crown. A repellent pack with herbal medicine attaches magnetically to the visor area. A cooling pack attaches below the visor magnetically. The cooling pack contains a brittle protective film holding ammonium nitrate, surrounded by water. Puncture needles with magnetic fluid weights are positioned to pierce the film when side pressing protrusions are squeezed.

Claim 2 specifies the repellent pack has a matching magnetic segment and a zipper for refilling medicine. Claim 3 details the cooling pack’s symmetrical pressing protrusions and a magnetic conductive segment for attachment. Claim 4 states the protective film is centrally located within the cooling pack and made of brittle material. Claim 5 adds a fixed anti-mosquito veil below the cap body and a neck-covering yarn with an elastic band. Claim 6 describes the veil as mesh and the neck yarn as ice-silk fabric. Claim 7 introduces a weighted ring between the veil and neck yarn, coated with fluorescent material.

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 US production

This patent was filed only in China and has lapsed due to non-payment of fees. Consequently, the specific structural combination described is in the public domain in China and has no corresponding IP rights in the United States.

Two points to settle early:

  • Other patents may exist. While this specific combination is free to use, individual components like chemical instant-cold packs, magnetic hat attachments, or mesh veil structures may be covered by other US patents held by outdoor gear manufacturers or medical supply companies. A freedom-to-operate (FTO) review is recommended before tooling.
  • Chemical Handling. The ammonium nitrate/water mechanism involves hazardous materials. US regulations regarding consumer products containing reactive chemicals must be strictly adhered to.

Customization and manufacturing

What can be customized

AreaOptions
FabricBreathability ratings, moisture-wicking treatments, UV protection factor (UPF).
Visor StructureElastic support plate stiffness, insulation thickness, brim length.
Magnetic SystemMagnet strength (NdFeB vs Ferrite), strip geometry, attachment angle.
Cooling PackActivation force required, volume of water/ammonium nitrate, casing material.
Veil & Neck GuardMesh density, ice-silk blend ratios, elastic band tension, fluorescent pigment type.
Repellent FillType of herbal extract, sachet size, zipper quality.

Things to plan for (US market)

  • CPSC Regulations: General safety requirements for children’s products if marketed to kids (not specified here, assumed adult).
  • EPA/FIFRA: If the “mosquito repellent” makes efficacy claims, it may be regulated as a pesticide. Using inert ingredients or making only “odor masking” claims helps avoid strict registration, but legal review is essential.
  • DOT/Hazmat: Transporting ammonium nitrate requires compliance with hazardous materials shipping rules.
  • California Prop 65: Warning labels may be required for certain chemicals or finishes.

How a project runs

  1. Inquiry - Define target price, quantity, and feature set (e.g., with or without veil).
  2. Design - Engineer the magnetic alignment for the needles, select brittle film material, and finalize fabric specs.
  3. Prototype - Build sample caps and test cooling activation reliability and repellent fit.
  4. Pilot Run - Small batch production to verify assembly line efficiency and packaging safety.
  5. Production - Mass manufacture textiles, mold plastic packs, fill chemicals, and assemble.

Quantities & timeline

Textile cutting and sewing lines handle the cap body. Injection molding is required for the cooling pack casings and protrusions. The brittle film and chemical filling process needs specialized automated equipment to ensure safety and consistency. Send us your estimated quantities, target retail price, and preferred fabric specifications and we will reply with options.
