Containment systems and components for animal husbandry: nested covers
Provided are animal containment systems and components, including single-use animal containment cages and modular rack units. Also provided are methods for assembling and using components of the animal containment systems.
1. A nested set of rodent containment cage covers, comprising a plurality of rodent containment cage covers, that are about 70% nested or more; each of which cage covers are constructed of a polymer and comprise at least one corner or edge in an interior of a cage when a cover is affixed to a cage base; which at least one corner or edge is accessible to a rodent that can be contained in the cage, and is defined by surfaces having an angle α greater than 180 degrees and less than 360 degrees and a minimum radius φ with φ=0.25/(tan((pi/360)(360−α))) inches.
2. The nested set of rodent containment cage covers of claim 1 , wherein each rodent containment cage cover comprises an air exhaust aperture and/or an air inlet aperture.
3. The nested set of rodent containment cage covers of claim 1 , wherein each of the rodent containment cage covers comprises one or more air exhaust connectors.
4. The nested set of rodent containment cage covers of claim 1 , wherein each of the rodent containment cage covers comprises one or more air supply connectors.
5. The nested set of rodent containment cage covers of claim 1 , wherein the rodent containment cage covers are about 80% nested or more.
6. The nested set of rodent containment cage covers of claim 1 , wherein the rodent containment cage covers are about 85% nested or more.
7. The nested set of rodent containment cage covers of claims 1 , wherein the rodent containment cage covers are about 90% to about 95% nested.
8. The nested set of rodent containment cage covers of claim 1 , wherein each rodent containment cage cover comprises an indent or boss that butts a corresponding indent or boss of an adjacent nested rodent containment cage cover.
9. The nested set of rodent containment cage covers of claim 8 , wherein the indent or boss facilitates separation of the nested rodent containment cage covers from one another.
10. The nested set of rodent containment cage covers of claim 8 , wherein the edges or corners of the boss or indent are defined by a radius of 0.03 inches or less.
11. The nested set of rodent containment cage covers of claim 1 , wherein the polymer is polyethylene teraphthalate.
12. The nested set of rodent containment cage covers of claim 6 , wherein the nesting separation member is a curved member or indent member located in or near a flange member.
13. The nested set of rodent containment cage covers of claim 12 , wherein the flange includes a lip member that interferes with a counterpart member of a nested cover.
14. The nested set of rodent containment cage covers of claim 1 , further comprising a water bottle holder in each cover.
15. The nested set of rodent containment cage covers of claim 14 , wherein each water bottle holder comprises a bottom that does not contact the water bottle holder of another nested cover.
16. The nested set of rodent containment cage covers of claim 1 , wherein each rodent containment cage cover comprises a nesting separation member that inhibits compression of nested components.
17. The nested set of rodent containment cage covers of claim 1 , wherein each rodent containment cage cover comprises a thickness from about 0.01 to about 0.08 inches.
18. The nested set of rodent containment cage covers of claim 1 , wherein each rodent containment cage cover comprises a thickness from about 0.01 to about 0.03 inches.
