  • Child-resistant container
    Patent number: 3980193
    Abstract: A container for pharmaceutical products has an un-removable dummy cap formation at one end, and an insert received in the other end, the insert having a hollow portion for receiving the end of an adult's finger so that the insert may be removed by deformation by digital pressure. The insert is so constructed as to be un-removable by a small child, who will in any case attempt unsuccessfully to remove the dummy cap rather than the insert.
