Patent ID: 7229107

Claim:
A security seal for containers which has at least one door that can be closed and unclosed by a closing mechanism, said security seal when activated being designed to place ink on the container when a door has been opened without proper deactivation of the security seal, comprising a gas cartridge in communication with a two position valve that can be opened and c 1 osed and having means to open said valve, whereby when said valve is open it allows gas to flow from said gas cartridge through said two position valve to a two way valve and having means to activate said two way valve, which in the activated position is in communication with a pressure hose which is looped around the closing mechanism of the container in a manner so that the closing mechanism can not be opened without removing or severing the pressure hose, said two way valve held in the activated position by pressure exerted on the two way valve from gas flowing from the gas cartridge, said two way valve having a security breached position, said two way valve having moving means to automatically move the two way valve to the security breached position if pressure in the pressure hose is reduced due to the hose being removed from the closing mechanism or being severed, said pressure means moving said two way valve to the security breached position where the two way valve is in communication with an ink reservoir which has the capability of releasing its contents onto the container when under pressure from said gas cartridge leaving a marker indicating that security has been breached.
