A child-resistant, tamper indicating closure according to the present invention includes a closure top having an outer edge. An annular skirt depends from the outer edge of the closure top, the skirt having a plurality of internal splines located on an inner surface. A tamper indicating band is connected to the skirt, for example, along a frangible line, the tamper indicating band having a plurality of external splines located on an outer surface. The internal and external splines may cooperate with a locking mechanism disposed on the container so that when a tab of the locking mechanism is not depressed, an inner locking member contacts an internal spline to lock the closure in place. When the tab is depressed, the inner locking members are free to rotate, but outer locking member contacts an external spline, so that if the closure is rotated, for example, in the counter-clockwise direction, the tamper indicating band separates from the skirt along a frangible line.

[ What is claimed is:] [1.] A child-resistant, tamper indicating closure for a container, comprising:a closure top;an annular skirt depending from the closure top, the skirt having a plurality of internal splines located on an inner surface; andan annular tamper indicating band connected to the skirt along a frangible line, the tamper indicating band having a plurality of external splines located on an outer surface, the each of the external splines including a locking surface and a ramped surface, each ramped surface inclined in a direction defined by the circumference of the closure. [8.] A child-resistant, tamper indicating closure and container, comprising:a container having a neck, the neck including:an external thread disposed on an outer surface of the neck;a locking mechanism disposed on the outer surface of the neck, the locking mechanism including:a flexible hinge connected to the outer surface of the neck below the external thread;an inner locking member connected to the flexible hinge;a radial extension connected to the inner locking member, the radial extension extending substantially radially outward from the inner locking member;a tab connected to an outer end of the radial extension; andan outer locking member associated with the tab; anda closure, including:a closure top having an outer edge;an annular skirt depending from the outer edge of the closure top, the skirt having a plurality of internal splines located on an inner surface, at least one internal spline in contact with the inner locking member to prevent removal of the closure from the container, and the skirt having an internal thread disposed on the inner surface, the internal thread cooperating with the external thread so that when the closure is rotated in a clockwise direction the closure is retained on the container and when the closure is rotated in a counter-clockwise direction the closure is removed from the container; anda tamper indicating band connected to the skirt along a frangible line, the tamper indicating band having a plurality of external splines located on an outer surface;wherein when the tab is depressed inwardly, the hinge flexes so that inner and outer locking members deflect from an outer position to an inner position, such that the outer locking member contacts at least one external spline so that when the closure is removed from the container, the tamper indicating band separates from the skirt along the frangible line.
