A package (100) for dispensing a granular product has a first hollow body member (110), a second hollow body member, and a pouring spout. The first hollow body member has a first exterior surface and opposite therefrom a first interior surface which defines a first internal volume. The second hollow body member has a second exterior surface, a second interior surface, a flow- regulating passage (132), and a dispensing passage separate from the flow- regulating passage. The second exterior surface defines a second external volume smaller than the first internal volume. Opposite the second exterior surface, the second hollow interior surface defines a second internal volume (130). The pouring spout is operatively connected to the dispensing passage. When the first internal volume is at least about 50% full of a granular product, the package may be tilted for dispensing at a dispensing angle which causes A package for dispensing a granular product has a first hollow body member, a second hollow body member, and a pouring spout. The fist hollow body member has a first exterior surface and opposite therefrom a first interior surface which defines a second external volume. The second hollow body member has a second exterior surface, a second interior surface, a flow-regulating passage, and a dispensing passage separate from the flow-regulating passage. The second exterior surface defines a second ecternal bolume smaller than the first internal volume. Opposite the second exterior surface, the second hollow interior surface defines a second internal volume. The pouring spout is operatively connected to the dispensing passage. When the first internal volume is at least about 50% full of a granular product, the package may be tilted for dispensing at a dispensing angle which causes the granular product to flow from the first internal volume through the flow-regulating passage into the second internal volume and from the second internal volume through the dispensing passage out of the package. When the flow rate is measured and calculated at dispensing angles of 120~, 150~ and 180~, the standard deviation is less than about 30% of the average flow rate for each dispensing angle.

L~invention concerne un emballage (100) pour déverser un produit granulaire comportant un premier élément de corps creux (110), un deuxième élément de corps creux et un bec verseur. Le premier élément de corps creux présente une première surface extérieure et, opposée à celle-ci, une première surface intérieure définissant un premier volume interne. Le deuxième élément de corps creux présente une deuxième surface extérieure, une deuxième surface intérieure, un passage régulant l~écoulement (132), et un passage de déversement distinct du passage régulant l~écoulement. La deuxième surface extérieure définit un deuxième volume externe plus petit que le premier volume interne. A l~opposé de la deuxième surface extérieure, la deuxième surface intérieure définit un deuxième volume interne (130). Le bec verseur est rattaché de façon fonctionnelle au passage de déversement. Lorsque le premier volume interne est au moins à moitié rempli d~un produit granulaire, l~emballage peut être incliné selon un angle de déversement qui amène le produit granulaire à s~écouler du premier volume interne au deuxième volume interne, en passant par le passage régulant l~écoulement, et du deuxième volume interne à l~extérieur de l~emballage, en passant par le passage de déversement. Lorsque le dédit est mesuré et calculé pour des angles de déversement de 120°, 150° et 180°, l~écart type est inférieur à 30% environ du débit moyen pour chaque angle de déversement.
