What the claims cover, in plain language
Claim 1 - a handle for a bath scrubber with a cord-lock inside that grips the scrubber strap so it does not slide, and an elastic part inside the handle; the strap passes through the cord-lock and is connected to the elastic part. The cord-lock has a spring chamber with at least two through-holes, a spring inside it, and a button with at least two holes matching the through-holes; the strap passes through both.
Claim 2 - the elastic part is a tension spring. Claim 3 - the elastic part is a rubber band. Claims 4-5 - a non-slip material on the handle, such as a rubber ring around it.
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 it lapsed in 2019 because annual fees were not paid. It no longer restricts anyone - in China or elsewhere.
Before production, keep in mind:
- Other patents may exist. Back scrubbers and cord-lock fasteners are common products, and some designs may be patented in the US. Use your own styling and have a freedom-to-operate (FTO) search done by a US patent attorney before volume production.

Things to plan for (US market)
- Wet environment - use rust-resistant springs and drain holes so the handles dry out.
- Hygiene - replaceable straps help; give care instructions (rinse and hang to dry).
- Claims - keep to cleaning and exfoliating; avoid medical skin claims.
How a project runs

- Design - handle shape, lock and tension part.
- Prototype - samples tested for grip, lock strength and length change.
