Abstract
Det er beskrevet en plastskumstruktur med lukkede celler omfattende et plastskum (10) som definerer et stort antall kanaler (13) som strekker seg fra skummets overflate og inn i skummet. Kanalene har ingen bestemt retning i forhold til skummets langsgående utstrekning, og strekker seg fortrinnsvis perpendikulært på skumstrukturens langsgående utstrekning. Kanalene er i gasskommunikasjon med miljøet på utsiden av skumstrukturen, og gir forbedret avgivelse av esemiddel. Dessuten er det beskrevet en fremgangsmåte for fremstilling av en plastskumstruktur omfattende (a) å tilveiebringe plast- skummet og (b) å perforere skummet i sin overflate under dannelse av et stort antall kanaler som strekker seg fra overflaten og inn i skummet under dannelse av skumstrukturen. i O i ~5C 2 ^o C,
