Access-limiting mechanism (10) limits access to a container (12). Access is controlled by moving a slider (18) back and forth along a plastic zipper (14), opening and closing the zipper. The access-limiting mechanism includes, in addition to the slider, a coupler (20). The coupler can stay fixed, immovable, at a given location, relative to the zipper; or can be moved along the zipper. As the slider moves close to the coupler, the slider and coupler are releasably coupled to each other, limiting the ability of the slider to open the zipper. Access can be further limited by adding a second control mechanism such as a cover (42), optionally a latching cover, overlying one or both of the slider and coupler. To open the container, the slider and coupler, and/or as applies the cover, are released from respective coupling or latching arrangements. |
