Tamper indicator for a locking seal
First Claim
1. A device for visually indicating an attempt to tamper with or defeat a locking seal, the locking seal being of the type having a lock body containing a passageway, a bolt having an end which is inserted and received in the passageway, and means within the lock body for preventing removal of the inserted bolt end therefrom:
- wherein the device comprises;
a frangible, brittle shroud adapted to surround the lock body, the shroud cracking, chipping or fracturing upon the application thereto of low force during an attempt to tamper with or defeat the seal by disassociating the lock body from the bolt, anda frangible, brittle flange integral with the shroud and adapted to surround the bolt at the point of entry of its end into the passageway, the flange cracking, chipping or fracturing upon the application of low force either exteriority thereto or between the flange and the bolt either, during an attempt to tamper with or defeat the seal by removing the bolt from the lock body or inserting a removal-preventing-means-defeating object into the passageway;
cracking, chipping or fracturing of the shroud or the flange providing a visual indication of an attempt to tamper with or defeat the seal.

Abstract
A tamper-indicating seal of the type having a bolt retained in a lock body, wherein the lock body is surrounded by a shroud of frangible, brittle material and provided with a grooved outer surface and flanged entrance way for receiving and surrounding the bolt end, whereby the shroud is easily fractured, thus providing visual indication of tampering. Visual detection of tampering may be enhanced by a coating applied to the outer surface of the shroud.

21. A device for visually indicating an attempt to tamper with or defeat a locking seal, the seal being of the type having a body containing a passageway, a member having a portion insertable and receivable in the passageway, and means within the body for preventing removal of the inserted portion therefrom;
- wherein the device comprises;
a frangible, brittle shroud adapted to overlie those portions of the body to which seal-tampering or -defeating forces are expected to be applied, the material, dimensions and configurations of the shroud being selected so that the shroud will crack, chip or fracture upon the application thereto of low force during an attempt to tamper with or defeat the seal, and a frangible, brittle flange secured to the shroud and adapted to overlie portions of the member at or near its point of entry into the passageway to which seal-tampering or -defeating forces are expected to be applied, the material, dimensions and configuration of the flange being selected so that the flange will crack, chip or fracture upon the application of low force either exteriorly thereto or between the flange and the member during an attempt to tamper with or defeat the seal by either removing the member from the body or inserting a removal-preventing-means-defating object into the passageway. - View Dependent Claims (22, 23)
