Abstract
A child resistant dispensing closure characterized by a closure member and a lid member which is mounted on the closure member for movement between closed and open positions. A peripheral edge of the lid member abuts an annular shoulder provided on the closure member in the closed position, the point of abutment being concealed by an annular ring provided on the closure member. In the closed position, thickened portions provided on the peripheral edge of the lid member engage in recesses formed in the annular shoulder. The lid member is adapted to be moved upwardly from the closed to an open position when a user applies with one hand a manual compressive force to a panel provided on the exterior skirt of the closure member. This manual force results in deformation of the panel inwardly into a slot formed clearly through an enlarged portion of the shoulder. As a result, a slight separation occurs between the peripheral edge of the lid member and the shoulder so as to allow the user, with the other hand and while continuing to compress the panel, to engage the peripheral edge of the lid member for moving the lid member to the open position.
