ABSTRACT:
A container closure device for a dispensing package container includes a shell having a pair of opposed face plates, a top plate, and a side panel in substantially orthogonal relationship. The face plates are resiliently urged toward each other for grippingly engaging the container. An elastomer material within the shell provides an air-tight seal with the container. Locking ridges within the face plates interact with a top wall and an end wall of the container for providing a snap-fitting engagement with the container. In an alternate embodiment, the face plates are independently displaceable with respect to the side panel for providing, gripping closure over a range of package widths. In another embodiment the shell is comprised of adjustably interfitting components for providing width adjustment.
