A package for granular material, particularly coffee beans, of the type of a metal can (1) with a withdrawable neck (2) of flexible plastic secured by a ring (3) clamped on the opening (4) of the can (1). The can comprises cone (5) at this level, and a protective snap-on cap (7) that snaps on to the metal part of the clamping ring (3) which protects the withdrawable neck (2), itself closed by a screw cap (8) and between the neck (2) and the threaded cap (8) there is an apertured ring (9) of a valve which serves as a cap release valve. The end of the withdrawable neck (2) is screw threaded and receives a device serving as a dispensing connecting closure (12) which comprises, at its first end, an adapter cone (13) followed by a screw-threaded cylindrical portion (14) which permits securement to a screw-threaded end (11) of the neck (2). The adapter cone (13) of the connector closure (12) is sufficiently large that the can (1) will be stable when supported by its cone (5) on the connector closure (12).
