AN OPEN AND FLEXIBLE PACKAGE AND A PROCESS FOR ITS PRODUCTION

摘要

The packaging is in the form of a capsule containing a powdery composition for a drink, having a body of frustoconical shape or inverted frustoconical shape and a membrane acting as a cover. The capsule is leaktight with respect to extraction by a fluid under pressure, that is to say the flow of fluid is directed through the bed of powdery composition. It can be deformed during extraction and fitted to various types of espresso machines without modifying the parts of these machines.
