1. A child-resistant flip-top closure comprising:
a base having a skirt for engaging a container, and a top shelf with a dispensing opening; a lid attached to the base through a hinge; and a child-resistant locking mechanism for inhibiting opening of the flip-top closure, the locking mechanism including:
one locking tab on the lid, the tab extending vertically upward from a portion of the lid and terminating in a locking lip,a central actuation button attached to the tab through an integral connecting rib so that the button is spaced forward of the tab,at least two barrier walls located adjacent to the actuation button, the barrier walls formed integral with the base and extending upward therefrom and on either side of the actuation button, the barrier walls terminating at or above a top of the button, each barrier wall including a locking ledge formed on a rear side of the wall, the locking ledges configured to engage the locking lip of the tab so as to provide an interlock between the lid and the base,wherein the locking tab extends laterally past the barrier walls, and wherein the locking ledges and locking lip include sloped surfaces to provide a mating interlock designed to restrict or inhibit the locking lip from easily sliding laterally away from the locking ledges, andwherein rearward pressure on the central actuation button can deflect the locking lip rearwardly into a deflected position out of engagement with the locking ledges of the at least two barrier walls, and wherein in the deflected position upward force on the central actuation button can raise and open the lid. |
