What the claims cover, in plain language
Claim 1 - A wind coat comprising a wind coat body and an inner bag. The wind coat body includes an outer cover and a liner joined together at their edges. The inner bag is arranged between the outer cover and the liner. A dismounting mouth is provided at the back waist lining, through which the inner bag is placed between the outer cover and liner. A connection sleeve is set inside the outer cover cuff; its outside connects to the outer cover, and its inner side flexibly connects to the liner cuff. The left front plackets on both sides of the inner bag flexibly connect to the inner side of the outer cover’s left front placket.
Claim 2 - The two sides of the dismounting mouth can be linked using a zipper (draw chain link). Claim 3 - The connection sleeve can be connected to the liner cuff through thread gluing. Claim 4 - The inner bag’s left front and the outer cover’s left front inner side are connected using a slide fastener.
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 is lapsed, so it no longer restricts anyone in China either. It has no US or other foreign counterpart.
Two points to settle early:
- Other patents may exist. Barth Darkow Christine holds a later foreign patent (WO2020002044A1) citing this document in the outerwear field, so a freedom-to-operate (FTO) review of the removable liner mechanism, back-opening placement, and cuff connection methods is recommended before tooling.
- Fabric performance specifications. The patent names materials like PU skin and silk floss wadding but does not define thickness, weight, or thermal ratings; these must be set in design and confirmed on prototypes to meet buyer expectations.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Outer cover material | PU skin, woven nylon, polyester blends, or custom fabrics |
| Inner bag insulation | Silk floss wadding, synthetic down, quilted cotton, or fleece |
| Closure types | Zippers, snap buttons, hook-and-loop, or thread gluing for the dismounting mouth and cuffs |
| Sizing | Standard US sizing (S-XXL) or custom grading |
| Colors and finishes | Dye colors, surface treatments, and printed patterns |
| Wadding pattern | Rhombus, oval, or channel quilting to secure the insulation |
Things to plan for (US market)
- Textile labeling (Textile Fiber Products Identification Act, 16 CFR 303) - Requires accurate disclosure of fiber content by percentage, country of origin, and manufacturer identity on the garment label.
- Care labeling (16 CFR 423) - Must provide clear washing, drying, and ironing instructions, especially critical for a multi-component garment where the outer cover and inner bag may have different care requirements.
- Flammability (16 CFR 1610) - General wearing apparel must meet the standard for flammability of clothing textiles.
- California Proposition 65 - Materials such as PU coatings, dyes, and synthetic wadding must be screened for listed chemicals.
How a project runs
- Inquiry - Target market, preferred materials, size range, order quantity, and required features.
- Design - Pattern drafting for the outer cover, liner, and inner bag; specifying connection points at the cuffs, front placket, and back dismounting mouth.
- Prototype - Sewing samples to test the fit, the ease of inserting and removing the inner bag, and the durability of the flexible connections.
- Pilot run - Small batch production to verify assembly efficiency, check fabric shrinkage, and confirm care label accuracy.
- Production - Bulk cutting, sewing, quilting the inner bag wadding, assembling the connection sleeves, attaching closures, and final inspection.
Quantities & timeline
Cutting dies or laser templates are needed for each size in the outer cover, liner, and inner bag. Quilting machines require specific programming for the chosen wadding pattern (rhombus or oval). Sourcing specialized components like the connection sleeves and matching zippers for the dismounting mouth adds lead time. Textile testing for colorfastness, shrinkage, and flammability must be scheduled before bulk assembly begins.
