KCAP turns from idea to something more real. Davide explains the idea to Marco, and together they ask some friend, to help them creating a prototype. They call an engineer working for an big italian valve industry (il john) and an experienced patent attorney (carluccio). The journey begins.
As you can see KCAP had in its firts version a piston / spring valve system. Complex but robust, strong. The crown cap had 3 holes to deflate pressure, protected by an hydrophobic membrane.
