Abstract

A tamper-resistant containment package is described, including a container; a cover configured to engage with the container so that the container and cover form an enclosed volume; and at least one tamper-resistant mechanical fastener that is cooperative with the cover and container to render the containment package tamper-resistant when the container and cover are engaged in a sealed state isolating the enclosed volume from an ambient environment surrounding the containment package. Such containment package is usefully employed for storage and transport of chemical reagents that pose a health, safety, and/or environmental risk if released to an exterior environment of the containment package.

First claim

What is claimed is:

1. A tamper-resistant containment package, comprising:
a container having an outwardly extending flange having an engagement surface;
a cover engaged at a peripheral portion with the engagement surface of the flange of the container so that the container and cover form an enclosed volume;
an array of mechanical fasteners interconnecting the cover with the outwardly extending flange of the container engaging the peripheral portion of the cover, said array comprising:
a first sub-array of said mechanical fasteners, comprising seal mechanical fasteners that aggregately seal the engaged container flange and cover; and
a second sub-array of said mechanical fasteners, comprising tamper-resistant mechanical fasteners that interconnect the peripheral portion of the cover with the outwardly extending flange of the container engaging the cover, but which (i) aggregately in the absence of the first sub-array of said mechanical fasteners, do not seal the engaged container and cover, and (ii) by their tamper-resistant character prevent the cover from being disengaged from the container except by tampering removal thereof from the engaged container and cover.

2. The tamper-resistant containment package of claim 1 , wherein the second sub-array of said mechanical fasteners comprises tamper-resistant mechanical fasteners that are at least one of: (i) smaller in size than the seal mechanical fasteners of the first sub-array of said mechanical fasteners; (ii) non-removable by mechanical fastener tools adapted for removal of the seal mechanical fasteners; (iii) countersunk in the cover below a surface above which the seal mechanical fasteners of the first sub-array of said mechanical fasteners protrude; and (iv) characterized by a lock torque that is from 10 to 60% of lock torque of the seal mechanical fasteners of the first sub-array of said mechanical fasteners.

3. The tamper-resistant containment package of claim 2 , comprising at least two of features (i)-(iv).

4. The tamper-resistant containment package of claim 1 , further comprising at least one seal element intermediate the engaged container and cover.

5. The tamper-resistant containment package of claim 4 , wherein the at least one seal element comprises a gasket.

6. The tamper-resistant containment package of claim 1 , wherein the container is configured to be heated to transmit thermal energy to solid material in the enclosed volume.

7. The tamper-resistant containment package of claim 6 , in combination with a heater adapted to transmit the thermal energy to the solid material in the enclosed volume.

8. The tamper-resistant containment package of claim 6 , wherein the at least one support structure comprises at least one tray in the enclosed volume.

9. The tamper-resistant containment package of claim 1 , wherein the second sub-array of said mechanical fasteners comprises tamper-resistant mechanical fasteners that are non-removable by mechanical fastener tools adapted for removal of the seal mechanical fasteners.

10. The tamper-resistant containment package of claim 1 , wherein the second sub-array of said mechanical fasteners comprises tamper-resistant mechanical fasteners that are characterized by a lock torque that is from 10 to 60% of lock torque of the seal mechanical fasteners of the first sub-array of said mechanical fasteners.

11. The tamper-resistant containment package of claim 1 ,
wherein at least one of the tamper-resistant mechanical fasteners engages a sealing bracket so that the sealing bracket exerts compression on the flange of the container and the cover for sealing of the container and cover in a sealed state isolating the enclosed volume from an ambient environment.

12. The tamper-resistant containment package of claim 11 , wherein the at least one tamper-resistant mechanical fastener is effective to maintain the container and cover in the sealed state.

13. The tamper-resistant containment package of claim 11 , wherein the at least one tamper-resistant mechanical fastener threadably engages the cover and container.

14. A tamper-resistant package, comprising:
a chemical reagent container having an outwardly extending flange having an engagement surface;
a cover engaged at a peripheral portion with the engagement surface of the flange of the chemical reagent container so that the container and cover form an enclosed volume;
at least one seal element intermediate the engaged container and cover;
an array of mechanical fasteners interconnecting the cover with the outwardly extending flange portion of the container engaging the peripheral portion of the cover, said array comprising:
a first sub-array of said mechanical fasteners, comprising seal mechanical fasteners that aggregately with the at least one seal element leak-tightly seal the engaged container flange and cover; and
a second sub-array of said mechanical fasteners, comprising tamper-resistant mechanical fasteners that interconnect the peripheral portion of the cover with the outwardly extending flange of the container engaging the cover, but which (i) aggregately in the absence of the first sub-array of said mechanical fasteners, do not leak-tightly seal the engaged container and cover, and (ii) by their tamper-resistant character prevent the cover from being disengaged from the container except by tampering removal thereof from the engaged container and cover.

15. The tamper-resistant package of claim 14 , wherein the tamper-resistant mechanical fasteners have a lock torque that is from 10% to 60% of lock torque of the seal mechanical fasteners.
