ABSTRACT:
A tamper indicator includes a first indicator element coupled to a first cylindrical element, a second indicator element positioned within a second cylindrical element and displaceable between a first position spaced apart from the first indicator element and a second position contacting the first indicator element. The first indicator element changes visual states when it contacts the second indicator element. A biasing device biases the first indicator element toward the second indicator element. A locking system maintains the first and second indicator elements in a locked, spaced apart configuration while the first and second cylindrical elements remain in a first location. The locking device enables relative movement to occur between the first and second indicator elements after the first and second cylindrical elements have been displaced from the first position into a second position. The locking device enables the biasing device to displace the first and second indicator elements together to establish contact and to effect the change in visual state of the first indicator element upon displacement of the first and second cylindrical elements from the second position into a third position.
