A perforating single-use impact indicator consisting of three independent engaging dements: a perforating sealed container: a sensitive dement; content consisting of a plurality of associated components. The sensitive element in the collar of the perforating sealed container operates as a plug on the perforating sealed container in such a way that the said sensitive element can be activated directly or indirectly when the components forming the content have been mixed or moved subsequent to the deceleration caused by an impact to the package to which the impact indicator of the invention is attached. The visual appearance of the sensitive element definitively changes when in direct contact with one of the components forming the content or when subjected to a change in temperature or to a gas release resulting from the mixing or movement of the components forming the content. |
