ABSTRACT:
The invention describes a pouring spout device, comprising a reclosable closure, and a spout fitment having a planar base and a tubular side wall defining a pouring zone therein and a flap disposed at a lower end of the side wall, a cam follower extending upward from said flap, wherein the closure retained on said fitment has an end wall and a tubular side wall, wherein the end wall has a first cam depending therefrom and engageable with said cam follower, and wherein the first cam contacting the cam follower during rotation of the closure. To avoid breakage of the cam follower, when the reclosable closure is replaced on the spout fitment, a second cam is formed on the reclosable closure and disposed radially outermost of the first cam. When the cam follower reaches the end region, it can move radially inwardly returning to the surface of the first cam.
