A child-resistant package includes a container having a body with an open end for dispensing product. A shoulder on the body is positioned adjacent to the open end and has an external surface. A circumferential groove is recessed radially inwardly from the shoulder surface at an end of the shoulder remote from the container end. A bead around the shoulder extends radially outwardly from the shoulder surface and is spaced from the groove and the container end, and at least one external axially extending channel is parallel to the axis of the shoulder surface and extends into the surface from the groove through the shoulder and the bead. A cup-shaped overcap has an open end, at least one internal lug adjacent to the open end for receipt in the groove on the container shoulder, and a radially inwardly extending bead around an inner periphery of the cap spaced from the open end for snap-fit over the radially outwardly extending bead on the container shoulder. Indicia on the overcap and the container body facilitate axial alignment of the lug with the channel for removal of the overcap from the container. Snap-fit of the beads on the overcap and the shoulder stabilize the overcap on the container and reduce the mechanical advantage that would otherwise be obtained by grasping and bending the overcap with respect to the container body.
