ABSTRACT:
A gravity impact indicator for shipping containers carrying valuable delicate cargo. The indicator comprises a sealed case, within the hollow interior of which a weight is suspended from an elongated coil spring. When the container is subjected to gravity impact, such as being dropped, the force moves the weight downwardly within the case. A flat spring extends transversely to the weight and engages ratchet teeth carried by the case to hold the weight in the lowermost position to which it is moved. Indicia may be carried by the case to designate the amount of impact. Track means and the inner surfaces of the case guide the weight against tipping during its downward movement.
