the hinge as shown in fig4 until the annulus portion reaches the correct position the annulus portion 24 is then pivoted about the hinge 23 to move to the expanded position and due to the corner 40 this may be accomplished by reversing the direction of movement of cup 28 in the expanded position the annulus portion has a greater length in the radial direction and becomes compressed between the surface 25 and central portion 21 and surface 33 is resiliently urged against surface 25 while inside surface 34 is in close proximity or abutting engagement with the peripheral surface of central portion 21 as an alternative to pulling on the central portion a force may be applied to the outer peripheral portion of the annulus portion or this in combination with a pull exterted on the tool to move the central portion in a direction out of the orifice in removing the closure 20 a sufficient pulling force is exerted on the cup 28 an alternative procedure would be to first push the tool to force the closure into the container turn the closure at an angle and then pull the closure through the orifice in this case only a portion of the annulus portion need contract to come back through the orifice alternative structures on the central portion are illustrated in fig8 and 9 to serve as means for gripping the closure a male stud 38 projects up from.
