Term used in association law. An “ideal” association is the most frequent and typical form of an association. A non-profit purpose is not directly aimed at economic activity and therefore not at generating profits. 
Non-profit purposes include:
Common-benefit purposes: serve to promote the public in general, the common good at spiritual, cultural, moral or material level.
Charitable purposes: serve to support/promote persons in need of material or personal help
Ecclesiastic purposes: serve to promote recognised churches and religious communities
