1. A package comprising;
a container, said container having an open end and containing a particulate laundry scent additive, said particulate laundry scent additive comprising perfume;
a dosing cup comprising a closed end, a peripheral rim, and a wall extending from said closed end to said peripheral rim to define a dosing volume, wherein said dosing cup comprises a vent opening in said closed end or in said wall, wherein said vent opening is sized and dimensioned to retain said particulate laundry scent additive, and wherein said vent opening serves as a conduit for perfumed air residing in interstitial spaces between particles of said particulate laundry scent additive to be expelled from said container; and
a shrink sleeve wrapping around said container and at least a portion of said wall of said dosing cup thereby providing a mechanism of engagement between said dosing cup and said container.

2. The package of claim 1 , wherein said shrink sleeve comprises a line of weakness.

5. The package of claim 4 , wherein said wall has a broadest dimension at an open end of said dosing cup defined by said peripheral rim.

6. A method of sampling the particulate laundry scent additive from the package of claim 5 comprising the steps of squeezing said container to expel perfumed air from said container through said vent opening and smelling said perfumed air.

7. The package of claim 5 , wherein said vent opening is unobstructed by said shrink sleeve.

8. The package of claim 7 , wherein a mass of perfume expelled from the container when tested by the Perfume Expulsion Test Method is more than about 1 ng.

9. The package of claim 8 , wherein said perfume comprises perfume microcapsules.

10. A method of sampling the particulate laundry scent additive from the package of claim 1 comprising the steps of squeezing said container to expel perfumed air from said container through said vent opening and smelling said perfumed air.
