Inventor seeks global manufacturer to license castor wheel cover

This invention is an aftermarket, injection moulded, fitted and self-sealing castor wheel cover manufactured from clear or coloured Liquid Silicone Rubber (LSR), or Thermoplastic Elastomer (TPE), which makes the cleaning of equipment for use in high level hygiene environments more time efficient and sanitary.


This invention is a world first with global health and safety implications.

Castor mounted units are often used by many organisations within hygiene and cleanroom areas. The cover is designed to prevent contamination of castor wheels within; food, pharmaceutical, biological, medical, automotive, aerospace, optical, nanotechnology and military industries. As well as laboratory and research facilities.

Dishwasher and autoclave safe, the cover could be offered in four colours and clear: white for cleanroom applications, orange for safety, metallic silver to mimic stainless steel for aesthetic considerations and grey to match industry standard flooring colours. Custom colour matching and logo embossing will be available as an option.

At the end of a shift, or in the event of contamination, the user can easily remove the cover, put it through a dishwasher or Autoclave, and replace the cover saving valuable time; steam cleaning a four-wheeled unit normally takes 12 – 15 minutes, but by using the cover it would only take one cleaning cycle (five minutes) of a dishwasher or autoclave to do the 12 wheels of four units, ensuring the units are fully regulatory compliant.

No more contaminated castor wheels.

Given a potential licensees current business profile the only capital investment would be the tooling costs. And the cover is designed for a one step fully automated manufacturing process to save on those costs.

The individuals who will benefit most are the customers, the people at the coal face:

  • Environmental health officers in knowing that the public are protected from a potential source of contamination;
  • Compliance directors by knowing that their company is satisfying the regulations and protecting its customers;
  • End users, the people who clean the equipment, that supports these businesses in achieving their mission statement, by saving them time and work.

Nick Davis, creator of the cover, states: “This invention is a world first. It is such a simple idea, as the best ones often are, that solves a need for any organisation that utilises castor mounted units in hygiene and cleanroom areas.

“I was very surprised when the patent search came back confirming that I am the first person on the planet to patent this idea. I own the UK patent and have multiple patent protections in other overseas jurisdictions including the EU, USA, China, South Korea and Japan.”

He also adds: “The cover is now a completed project designed for a cost-effective manufacturing process with a marketing programme, with a motivated sales force and a resilient client base.

“Given potential licensees’ current business profile the only capital investment would be the tooling costs and the cover is designed for a one step fully automated manufacturing process to save on those costs.

“An independent review of the markets forecast sales of 94bn+ units worldwide.”
