each segment of the plurality of segments of the band clamp having a band portion with a first end and an opposing second end, the first and second ends each having an attachment portion, each band portion defining a portion of the interior surface with the second profile; and

further comprising a plurality of fasteners, each fastener disposed to secure adjacent attachment portions of consecutive ones of the plurality of segments.

5. The combination of claim 2 , wherein:

the first and second complementary profiles are configured to produce a clamping force that biases the cover toward the engine block.

6. The combination of claim 1 , wherein:

the first profile extends around the opening of the engine block with a periphery having a shape of a polygon; and

the exterior surface defined by the first and second flanges is constrained by the band clamp at each corner of the polygon-shaped periphery.

7. The combination of claim 1 , wherein:

the first and second complementary profiles are V-shaped, C-shaped, cove-shaped, bevel-edge-shaped, or any combination thereof.

8. The combination of claim 4 , wherein:

the first profile extends around the opening of the engine block with a periphery having a shape of a polygon; and

each band portion extends from one side to an adjacent side of the polygon.

9. The combination of claim 8 , wherein:

the polygon is a four-sided polygon; and

the plurality of segments is four segments.

10. The combination of claim 1 , wherein:

the engine block is made from a metal;

the cover is made from a glass reinforced polyamide; and

the band clamp is made from a metal.

11. The combination of claim 4 , wherein:

the adjacent attachment portions of consecutive ones of the plurality of segments are at least partially spaced apart from each other.

12. The combination of claim 2 , further comprising:

an elastomer layer disposed between the interior surface of the band clamp and the exterior surface defined by the first and second flanges.

13. The combination of claim 1 , wherein:

the first engagement surface comprises a planar surface having a first mating feature; and

the second engagement surface comprises a planar surface having a second mating feature that is complementary with the first mating feature.

14. The combination of claim 13 , wherein:

the first mating feature is one of a projection and a recess; and

the second mating feature is a complementary one of the projection and the recess.

15. The combination of claim 3 , wherein:

at least one of the first engagement surface and the second engagement surface comprises a recessed region; and

the curable sealant is disposed within the recessed region.

16. A containment assembly for flowable materials usable in an automotive vehicle, comprising:

an engine block includes an opening configured to provide access to an interior volume, a first flange having a periphery that surrounds the opening, and a first engagement surface disposed proximate the first flange;

a cover having a second flange disposed around a periphery of the cover, and a second engagement surface disposed proximate the second flange, the second engagement surface configured to mate with the first engagement surface, wherein the first engagement surface and the second engagement surface are disposed in engagement with each other, wherein the first flange and the second flange in combination define an exterior surface having a first profile, the first profile having a periphery having a plurality of associated sides and corners; and

a band clamp having an interior surface with a second profile that is complementary with the first profile, the band clamp having a plurality of individual segments equal in number to a number of the corners of the first profile, each segment of the plurality of individual segments arranged consecutively in a closed loop fashion around the first profile beginning at one side, continuing around an associated corner, and terminating at an adjacent side of the first profile, wherein the interior surface of the band clamp is disposed in clamping arrangement with the exterior surface defined by the first and second flanges; and

a curable sealant disposed between the first and second engagement surfaces.

17. The oil containment assembly of claim 16 , wherein:
