A tamper evident cap assembly, more particularly a combination of vial and cap assembly, assures the integrity of a specimen and of the specimen collection process. The screw cap is locked to the screw threads of a vial, when the vial is empty, with one of two latches that are integral to the cap assembly and can lock the cap to the vial. The lock is broken in the presence of the specimen donor or in the presence of a witness who can testify as to chain of custody, a specimen is placed in the vial, following which the cap is locked to the vial with the other of the two latches, which is broken when received by a testing laboratory. A loop formed to encircle the vial is connected by a tether to the cap and slipped onto the vial. At least one restraining rib on the vial is spaced below the screw thread top and is sized to permit the loop to be forced upwardly thereover to be restrained from downward movement. In addition, a limiting flange on the vial is spaced below the screw thread and above the loop restraining rib sufficient to accommodate the loop, and is sized to limit upward movement of the loop. In a specific embodiment, latch staples extend from the cap which can be inserted into, and irreversibly lock with, respective hasps extending from the loop.

1. A method for assuring the integrity of a specimen from a donor, comprising:providing a vial, a cap for the vial, and two latches capable of locking the cap to the vial; locking the cap to the vial, when the vial is empty, with one of the two latches; breaking the lock; inserting a specimen in the
1. A method for assuring the integrity of a specimen from a donor, comprising:providing a vial, a cap for the vial, and two latches capable of locking the cap to the vial; locking the cap to the vial, when the vial is empty, with one of the two latches; breaking the lock; inserting a specimen in the vial; locking the cap to the vial with the other of the two latches; and wherein the vial has a screw thread top and the cap is screwable thereon, whereby unscrewing rotation of the cap can break either locked latch. 2. The method of claim 1 which said one of the two latches is broken in the presence of the specimen donor.3. The method of claim 2 which the cap is locked with said other of the two latches in the presence of the specimen donor.4. The method of claim 1 which said one of the two latches is broken in the presence of a witness who can testify as to chain of custody.5. The method of clam 4 in which the cap is locked with said other of the two latches in the presence of a witness who can testify as to chain of custody.6. The method of claim 1 in which there is a loop connected by a tether to the cap and formed to encircle the vial below the screw thread top, each latch having a component extending from the loop and a corresponding component extending from the cap lockable to the loop component when the cap is screwed onto the vial.7. The method of claim 6 in which the vial is formed with at least one restraining rib spaced below its screw thread top and sized to permit the loop to be forced upwardly thereover and to thereafter restrain the loop from downward movement.8. The method of claim 7 in which the vial is formed with a limiting flange spaced below the screw thread top and above the loop restraining rib sufficient to accommodate the loop and sized to limit upward movement of the loop.9. The method of claim 1 in which one of the components of each of said latches is a latch staple and the corresponding component of each of said latches is a hasp.10. The method of claim 9 in which each loop latch component is a hasp and each cap latch component is a latch staple.11. The method of claim 1 in which each latch is irreversibly lockable.12. A method for assuring the integrity of a specimen from a donor, comprising:providing a vial having a screw thread top, a cap for the vial screwable thereon, a loop connected by a tether to the cap and formed to encircle the vial below the screw thread top, at least one restraining rib on the vial spaced below its screw thread top and sized to permit the loop to be forced upwardly thereover and to thereafter restrain the loop from downward movement, a limiting flange on the vial spaced below the screw thread top and above the loop restraining rib sufficient to accommodate the loop and sized to limit upward movement of the loop, and two latches capable of locking the cap to the vial, each latch having a component extending from the loop and a corresponding component extending from the cap lockable to the loop component when the cap is screwed onto the vial; locking the cap to the vial, when the vial is empty, with one of the two latches; unscrewing the cap whereby to break the lock in the presence of the specimen donor or in the presence of a witness who can testify as to chain of custody; inserting a specimen in the vial; and locking the cap to the vial with the other of the two latches in the presence of the specimen donor or in the presence of a witness who can testify as to chain of custody, the other of the two latches being breakable by unscrewing rotation of the cap. 13. The method of claim 12 in which one of the components of each of said latches is a latch staple and the corresponding component of each of said latches is a hasp.14. The method of claim 13 in which each loop latch component is a hasp and each cap latch component is a latch staple.15. The method of claim 12 in which each latch is irreversibly lockable.
