Details

Conventional aerosol spray can technology suspends fine solid or liquid particles of consumable and other ingredients in a gas, and expels them through a traditional spray nozzle in a diminishing pressurized stream. This process works until the can is empty of propellant, but not necessarily empty of ingredients.

Rocep-Lusol Holdings Ltd. of Scotland and Lindal Dispenser GmbH of Germany have developed an alternative to conventional spray can technology that does not require incendiary gasses to propel contents or emit high VOCs (volatile organic compounds).
 
The manufacturers claim that the product, known as the LinRoc Double Piston Can System with Actuators, is unique in that it facilitates a continuous spray of any viscous product, ranging from water to heavy creams and oils. The system is 100% recyclable, and as it does not require gasses to propel contents, it is non-flammable and transport risk-neutral, and does not contribute to ambient air pollution.
 
The can technology consists basically of three elements:
  • an uncontaminated and propellant-free environment for storing liquid and viscous ingredients
  • a wholly separate containment area for pressurized dead air
  • a spray valve.
The system relies on innovative physics and risk-neutral dead air to propel ingredients in a uniform stream or mist until the can is empty of ingredients.

Potential Benefits

This technology provides two main environmental advantages over traditional aerosol can technology:
  • Improved recyclability of the can materials
  • Reduced product wastage through improved dispensing of the product contents, leaving less residual material at the end-of-life. 

Intellectual Property

This is a patented product developed by Rocep-Lusol Holdings Ltd. Of Scotland and Lindal Dispenser GmbH of Germany.

 

 
 

Consultant View

This innovation demonstrates that even complex packaging solutions such as aerosol cans can be designed for recyclability. Although the immediate market is the personal care sector, it is possible to imagine this technology being adapted and used for products in the home improvement sector, such as spray paints, spray adhesives, etc.
