Abstract
A closure locking design is presented that is more resistant to a displacement/dislodgement force. A closure end strip is fixed to a closure end and received by a closure guide first section. A rotatable tube and hook assembly run vertically within a closure guide second section. When rotated to a locking position a hook member of the tube and hook assembly rotates through a slot cut in the guide and through a cutout in the closure end strip to restrictively engage the closure.
