Abstract
The system described here is a bolt-type seal lock which includes a bolt, having a shaft with proximal and distal portions and a head that is wider than the distal portion of the shaft and located at the proximal portion of the shaft; and a locking body having a passageway therethrough with first and second open ends on opposite sides of the locking body. The locking body is configured to receive and retain the shaft in locking engagement after the shaft has been inserted a predetermined extent into the first open end of the passageway, at which point the shaft cannot be withdrawn from the first open end of the passageway and to permit passage of the distal portion of the shaft through and out of the second open end of the passageway after separation of the head and the distal portion of the shaft.

19. A method of securing a shipping container before and after opening of the shipping container, comprising the steps of:
-
(a) providing a bolt-type seal lock, comprising, (i) a bolt comprising, (A) a shaft having a proximal portion and a distal portion, and (B) a head located at the proximal portion of the shaft, the head being wider than the distal portion of the shaft, and (ii) a locking body having a passageway therethrough with first and second open ends on opposite sides of the locking body; (b) inserting the distal portion of the shaft of the bolt, (i) through an opening in a locking structure of a door of the shipping container such that the shaft of the bolt must be withdrawn from the opening of the hasp in order to open the door of the shipping container without causing structural damage to the shipping container, the head of the bolt being too wide to pass through the opening in the locking structure of the door of the shipping container, and (ii) into the first open end of the passageway of the locking body a predetermined extent such that the locking body receives and retains the shaft of the bolt in locking engagement therewith; (c) separating the head and the distal portion of the shaft of the bolt; (d) withdrawing the head and remaining portion of the shaft of the bolt from the opening of the locking structure of the door of the shipping container for opening the door of the shipping container without causing structural damage to the shipping container; (e) passing the distal portion of the shaft of the bolt through and out of the second open end of the passageway after separation of the head and the distal portion of the shaft; (f) providing a second bolt comprising, (i) a shaft having a proximal portion and a distal portion, and (ii) a head located at the proximal portion of the shaft, the head being wider than the distal portion of the shaft; (g) inserting the distal portion of the shaft of the second bolt, (i) through the opening in the locking structure of the door of the shipping container such that the shaft of the second bolt must be withdrawn from the opening of the hasp in order to open the door of the shipping container without causing structural damage to the shipping container, the head of the second bolt being too wide to pass through the opening in the locking structure of the door of the shipping container, and (ii) into the first open end of the passageway of the locking body the predetermined extent such that the locking body receives and retains the shaft of the second bolt in locking engagement therewith. - View Dependent Claims (20, 21)
