  • Patent number: 5718347
    Abstract: A container and closure for medicine, pills or the like includes a latch connected to the closure by a living hinge. The closure is connected to the container opposite from the latch by a second living hinge. The latch is seated within a recess on the sidewall of the container to provide a child resistant package. A cavity is formed between the sidewall and the latch in the recess. The latch must be depressed by the user to free a portion of the latch from the recess. The remainder of the latch is dislodged from the recess by pressing on a region of the sidewall of the container. The closure can then be opened by grasping the latch and pulling upwardly thereby freeing the closure from the upper rim of the container. The unitary container and closure provide an effective child resistant package which is likewise easily opened by an adult or senior citizen.
