摘要
A package for flowable media and a snap lid which package and snap lid are both made from thermoplastic material, in which a collar-shaped head of the package surrounds a pouring aperture of the package, which collar-shaped head has a retaining ring on its outside, an inside annular surface, and an upper end having an edge with a snap catch, which upper end can be closed using the snap lid. The snap lid has a closing wall from which an annular sealing lip projects towards an inside of the package, and can be brought into contact with an inside surface of the edge in sealing engagement. The closing wall is provided with an outside catch for snap engagement with a snap catch of the edge of the head. The head of the package widens outwards and upwards at its edge, and both the inner surface of this edge and an outer surface of the sealing lip on the snap lid are curved convexly relative to each other. The invention also includes preforms for making the package of the invention.
