Security seal
First Claim
1. A security seal, comprising:
- a first seal member having a base portion and an elongated stem portion extending outward from said base portion, a first locking portion being provided substantially at an end of said stem portion distal to said base portion, and a conductive strip embedded within said stem portion and extending substantially from said base portion to said end of said stem portion; and
a second seal member having a second locking portion, said second locking portion being engagable to said first locking portion to secure said first seal member to said second seal member, contact portions of said conductive strip being provided substantially at opposite ends of said conductive strip for application of leads of a suitable continuity testing apparatus, whereby said continuity testing apparatus can be used to evidence breaking of said conductive strip and thereby tampering with said security seal.

Abstract
A security seal includes a first seal member having a first locking portion and a first detection circuit portion. A second seal member has a second locking portion and a second detection circuit portion. The first locking portion is engageable to the second locking portion to engage and irretrievably lock together the first seal member to the second seal member. Engagement of the first seal member to the second seal member operatively connects the first detection circuit portion to the second detection circuit portion to provide a combined detection circuit throughout the security seal. The first seal member preferably includes a spear having the first locking portion, and the second seal member includes a sleeve having the second locking portion. The spear is insertible into the sleeve to engage the first locking portion to the second locking portion, and to thereby engage the first seal member and the first detection circuit portion to the second seal member and the second detection circuit portion. Breaking of the security seal will break continuity of the combined detection circuit portions, which continuity is checked for evidence of tampering. In an alternative embodiment, a conductive strip is embedded within an elongated stem extending from the first seal member. The stem is engageable to the second seal member to form the security seal. Contact points allow testing of the continuity of the conductive strip as evidence of tampering. The seal members are preferably formed from a clear material with embedded indicia to provide a visual indication of tampering.

10. A security locking mechanism for a container door having a pair of aligned openings adapted to receive a lock, said locking mechanism comprising:
-
a first member having a stem and a base connected to one end of said stem, said stem including conductive means wholly embedded therein; a second member having a receptacle for lockably receiving said stem so that said conductive means is partially within said receptacle; wherein one of said first or second members has identifying indicia wholly embedded therein; a first access port within said first member for permitting electrical contact with said conductive means, and a second access port within said second member permitting electrical contact with said conductive means when said stem is lockably engaged with said receptacle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
