Weener Plastics' aerosol spray actuator for shoe deodorant

Weener Plastics has developed Carl, an innovative one-piece aerosol spray actuator to freshen up shoes. Carl benefits from a practical spray concept that is easy to apply, as it can be placed in an upside-down position in the shoe.

The large ribbed top surface gives good grip and stability. Upon actuation of the aerosol, it sprays to the front and the back in order to reach the whole inside, using two functional sprays that are generated using Integrated Spray technology. Different spray patterns are feasible, depending on the formulation and customer requirement.

Carl is an attractive, standard actuator that fits on 45mm tinplate cans and 45mm aluminium transfer shoulder cans. The spray actuator is supplied with a matching overcap for protection. Customization of the overcap is possible to create a distinctive look.

The first commercial samples of WPs Carl aerosol spray actuator will be available in October 2019, with full production planned for November 2019.


In line with WPs strategy to stimulate the circular economy, the Carl actuator is produced from Post Consumer Recycled (PCR) polypropylene (PP). There is no POM insert, so the mono material product can be easily recycled.

Integrated Spray Technology

Weener Plastics developed a proprietary spray solution with a patented technique, that integrates both the actuator and insert. The double spray orifices of the actuator are positioned just above the stem to optimise the control and performance when activating the aerosol. Special chambers and channel design stimulate the acceleration of particles into a swirling pattern.

This solution will be showcased at the Aerosol & Dispensing Forum in Paris from 29-30 January 2020.
