    Patent number: 7029178
    Abstract: A one-way, zip-locking closure for bag-type containers that include slider zipper arrangements. The locking mechanism includes a series of registration structures that is provided along one side of the mouth of the containers and a catch mechanism that is provided within the slider. The catch mechanism engages the series of registration structures as the slider is moved to close the mouth of the container, and thereby prevents movement of the slider in the opposite direction.
