Tamper indicating child resistant closure

A tamper indicating package comprising:

• a threaded closure, a container having a threaded neck to receive said closure, a lock member on said threaded neck below the threads and presenting a lock surface facing circumferentially in one direction and a ramp surface adjacent said lock surface and facing in the opposite circumferential direction, said closure including concentric inner and outer walls, a lock tab on said outer wall for engaging said lock surface upon opening rotation of said closure to prevent rotation beyond a predetermined point and being engageable with said ramp surface upon closing rotation to deflect said outer wall to pass said lock member upon rotation in a closing direction, said lock tab being deflectable radially outwardly to pass said lock surface upon radial inward squeezing of said outer wall at diametrically opposed points, a tamper indicating means detachably connected to said outer wall to maintain said lock tab circumferentially spaced from said lock surface in an initial position of said closure, ramp means on said container engageable with said outer skirt at said opposed points to prevent inner radial deflection of said diametrically spaced points when said closure in in said initial position, said tamper indicating element being removable from said closure to permit rotation in an opening direction from said initial position a limited amount to permit deflection of said radially spaced points for removal of said closure, said removed tamper indicating element giving evidence of possible prior opening.
