A reclosable package for a consumer product includes a zipper strip having male and female interlocking profiles. The former has a male interlocking member having a cross section in the shape of an asymmetric arrowhead. The latter has a female interlocking member in the form of two mutually curving members defining a channel therebetween. The male interlocking member is snappingly engaged into the channel to reclose the package. The asymmetric male interlocking member has an acute edge outward of the interior of the package, and a rounded edge facing the inside of the package. This asymmetry makes the package easier to open from within than from without.
