Pur foam dispensing means

Within the framework of my bachelor assignment for the Industrial Design Engineering education at the University of Twente I needed to develop PUR foam dispensing means for Robertpack Engineering BV in Zwolle which means would be positioned between the existing solutions, the small synthetic tube, which is, as a consumer product, provided with a container of PUR foam and the professional dispensing spray-gun which is, for example, used by construction companies and people working in the building trade.
