  • Security containers
    Patent number: 5992663
    Abstract: A security container has two dished parts (1, 2) that can be closed together rim (6) to rim (11), irreversibly engaging and making inaccessible a snap fitting (7, 13) within the container. A strop (3) with loops (4) in its ends has those loops placed over part of the snap fitting (13) before closure, leaving its bight (5) outside. The strop (3) is thus made captive when the container is closed. The strop (5) passes through an aperture formed by cutouts (10, 12) in the rims (6, 11).
