ABSTRACT:
A child-proof, senior-friendly safety closure for medicine containers is formed with a cylindrical wall including a continuous mid-level band and slotted upper and lower walls. The slotted walls, in conjunction with the mid-level band, form a plurality of lever-like locking elements which can be pivoted about the region of the mid-level band with which they are integrally associated. The associated receptacle is formed with a dispensing neck having an internally projecting locking flange arranged to engage with notches at lower ends of each of the cylindrically arrayed locking levers, the latter being resiliently biased to remain in locking engagement with the flange. To release the cap, an adult finger is inserted downward into the upper end of the cap, the dimensions of which are such that insertion of an adult finger causes the upper ends of the locking levers to be displaced radially outward. Radially outward displacement of the upper ends simultaneously releases the lower ends of the locking levers from the locking flange and allows the cap, which now is in a gripping relation to the finger, to be removed by withdrawing the finger. The internal diameter of the cap is such that the finger of an infant or young child is not large enough to displace all of the locking levers, and displacement of only a few of them is not effective to release the cap.
