  • Childproof container
    Patent number: 4383618
    Abstract: A glass container has an opening closed by a quick-release plastic cap. Each of the cap and bottle have double pitch threads in mating engagement. Lugs on the cap are in contact with lugs on the bottle which interfere with unthreading the cap. A lower end portion of the cap is deformable radially inwardly for causing the cap lugs to disengage from the bottle lugs whereby the cap may be unthreaded.
