Abstract
A tamper-indicating device is described. The device has a first glass body member and a second glass body member that are attached to each other through a hasp. The glass body members of the device can be tempered. The body members can be configured with hollow volumes into which powders, microparticles, liquids, gels, or combinations thereof are sealed. The choice, the amount, and the location of these materials can produce a visible, band pattern to provide each body member with a unique fingerprint identifier, which makes it extremely difficult to repair or replace once it is damaged in order to avoid tamper detection.

A tamper-indicating device, comprising:
- (a) a locking ring;
- (b) a first glass body member comprising a first end portion, a middle portion narrower than said first end portion, and a second end portion narrower than said middle portion, said middle portion having a circumferential recess for receiving said locking ring;
- (c) a second glass body member comprising a first end portion and a second end portion, said second end portion having an opening leading to an inner hollow volume defined by an inner cylindrical wall and an adjacent wall, said cylindrical wall further including an inner circumferential recess, said second glass body member configured such that when said second end portion and said middle portion of said first glass body are completely inserted inside said hollow portion of said second body, said circumferential recess of said first body and said circumferential recess of said second body are in alignment for receiving said locking ring to attach said first glass body member to said second glass body member.
