A child-resistant dispensing closure is snap-engageable and freely rotatable on a container neck. The closure has body and lid portions (14, 14' and 16, 16') one of which has two parts capable of relative rotation. One of the two parts (20A, 22A') is attached to the other portion of the closure by an integral hinge (18, 18') which enables the lid portion to be swung between closed and open positions as required for dispensing. A catch (68, 70 and 99, 97) between the lid and body portions is automatically engaged when the lid portion is closed. In order to subsequently release the catch for dispensing, it is necessary for the user to grasp the closure with both hands and rotate the relatively rotatable parts, possibly against the action of a return spring (64, 202, 100). The closure is intended for liquid products such as liquid soaps. |
