What the claims cover, in plain language

Claim 1 - a method of using a soil digging glove comprising a silica gel main body (1), a hard rubber top piece (2) at the middle front end, a rectangular mounting piece (3) with a T-shaped mounting groove (301) and limiting pieces (302), a splicing block (4) with clamping grooves (401) and bed knives (402), a connector (5) with a tubular insert (501) containing annular rubber stop blocks (502), a silica gel thumb mounting plate (6) with cutting pieces (601), and a bonded silica gel sealing ring (7). The splicing block embeds in the T-groove via the limiting pieces for soil planing; the connector inserts for soil capture during planting.

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 currently in force. Making or selling the patented configuration in China requires the owner’s permission. It has no US or other foreign counterpart.

Two points to settle early:

  • Other patents may exist. Wearable garden tools and silicone protective equipment are fields with numerous prior US and international patents covering modular attachments, ergonomic grips, and soil-handling inserts. A freedom-to-operate (FTO) review focused on the T-slot interchange mechanism and tubular soil-capture connector is needed before tooling.
  • Material specification. The claims specify silica gel for the body, plate, and seal, and hard rubber for the top piece and stop blocks; substituting other elastomers may avoid infringement but must be verified against the claim language and tested for durability.

Customization and manufacturing

What can be customized

AreaOptions
Glove sizeS / M / L / XL based on hand circumference
Shore hardnessSofter silicone for comfort, firmer for scraper rigidity
ColorPantone-matched silicone compounds
Blade geometryBed knife angle and count within the splicing block
Connector diameterTube bore sized for common plug dimensions
Thumb plateSingle or double cutting edge; serrated variant

Things to plan for (US market)

  • FDA 21 CFR 177.2600 - silicone rubber articles intended for repeated food contact, if the glove will be marketed for harvesting edible crops.
  • CPSC 16 CFR 1500 - sharp point and edge requirements apply to the metal-equivalent cutting pieces if any component is classified as a toy or children’s item.
  • California Prop 65 - uncured silicone additives and colorants must be screened.
  • ASTM D4157 - abrasion and tear testing for elastomeric protective gloves sold as safety equipment.

How a project runs

  1. Inquiry - sizes, Shore hardness, colors, attachment quantities.
  2. Design - silicone mold cavities, T-groove tolerances, blade and connector geometry.
  3. Prototype - molded samples for fit, insertion force, and soil retention tests.
  4. Pilot run - batch molding, bonding of sealing rings, attachment assembly.
  5. Production - liquid injection molding of silicone parts, secondary bonding, QC.

Quantities & timeline

Silicone main bodies, mounting pieces, plates, and seals each require dedicated injection molds; the splicing block and connector need precision molds for their interlocking features; bonding and assembly add labor steps. Tooling lead time depends on cavity count and whether multiple sizes share a mold base. Send us your sizes, Shore hardness, colors, attachment types, quantity and target price and we will reply with options.
