What the claims cover, in plain language
Claim 1 - a folding grater made of two panels folded together: one panel has large shredding holes, the other small shredding holes; or a slicing blade is set between the large holes on one panel, or between the small holes on the other.
Claim 2 - the panels are joined by a hinge. Claim 3 - each panel has a plastic or wooden edge with a stainless-steel plate set in the middle, carrying the holes or the blade. Claim 4 - the two panels are the same size.
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, so it no longer restricts anyone in China either. It has no US or other foreign counterpart.
Before production, keep in mind:
- Other patents may exist. Graters and folding kitchen tools have many US utility and design patents. Develop your own frame shape and styling and have a freedom-to-operate (FTO) search done by a US patent attorney before volume production.
- Simple product, crowded shelf. The value is in execution: blade sharpness, a solid hinge, non-slip feet and good packaging.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Size | Panel size and thickness - to be confirmed in design |
| Blades | Coarse and fine shredding holes, slicing blade, zester; stamped or photo-etched |
| Frames | PP or ABS with soft-grip edges, bamboo or beech wood |
| Hinge | Molded living hinge, pin hinge or detachable panels |
| Extras | Non-slip feet, a catch tray or container, blade cover |
| Branding | Frame colors, printed or engraved logo, retail card or box |
Things to plan for (US market)
- Food-contact materials - plastics, coatings and wood finishes must comply with FDA food-contact regulations (21 CFR); stainless steel grade should be food-safe (e.g. 304 or 420 for blades).
- California Proposition 65 - check frame materials and finishes.
- Packaging - sharp blades need protective covers and clear handling warnings.
- Dishwasher claims - test before labeling the product dishwasher safe, especially wooden frames.
How a project runs
- Inquiry - size, blade types, frame material and quantity.
- Design - blade patterns, hinge, frame shape and feet.
- Prototype - samples for grating tests on cheese and vegetables.
- Pilot run - small batch with food-contact testing.
- Production - volume production, packaging and shipping.
Quantities & timeline
Blades need stamping or etching tools and plastic frames need molds; wooden frames need little tooling. Send us your size, blade types, frame material, quantity and target price and we will reply with options.
