Abstract
A closure device for a flexible package having an opening is described as including a substantially concavo-convex closure strip mounted at the opening of the package with its convex face oriented toward the interior thereof. The closure strip is resiliently flexible between a stable undeflected position wherein it maintains the opening of the package in closed condition, and a stable deflected position wherein it maintains the opening in a substantially opened condition. The closure strip includes two non-parallel intersecting surfaces which are joined longitudinally along their intersection by a curved fillet-like section having a predetermined radius r. The intersecting surfaces each have a width greater than or equal to a minimum width w; and such surfaces are disposed relative to one another at a predetermined angle .alpha. as measured between the adjacent faces of such intersecting surfaces, wherrein angle .alpha. is greater than 0.degree. and less than 180.degree. and the value of r/w.sup.2 is greater than or equal to 0 mm.sup.-1 and less than or equal to approximately 0.04 mm.sup.-1 when the values r and w are measured in millimeter units. The closure device is adapted to adequately serve as a closure for the package while providing convenient and substantial access to the product within when deformed to its stable opened position.
