A container includes a sealing system coupled to an interior surface of the container's lid or cover. The sealing system includes a rotatable latch that, when rotated, cooperates with a number of gears to and a cam assembly formed in the lid to actuate a number of arms or links. In one embodiment, some of the arms extend approximately radially from a driven gear and operate to move an engagement member of the sealing assembly into contact with a complementary engagement member coupled to a base portion of the container. This engagement, in turn, compresses a seal or gasket located between the lid portion and the base portion of the container.

1. An equipment container comprising: a base portion forming a containment space to receive equipment, the base portion defining one or more projecting portions;a lid configured to secure to the base portion, the lid including a center portion;one or more deformable tangs each having a first end portion, an arcuate-shaped slider and an engagement portion on a second end portion, the arcuate-shaped slider being between the first and second end portions; one or more curved pathways each defined by an interior surface of the lid and a bracket secured to the lid, each of the one or more deformable tangs passing between a curved pathway of the one or more curved pathways, the one or more deformable tangs being slidable within the one or more curved pathways, the one or more curved pathways causing the first end portion and the second end portions to be perpendicular to one another; and a latch coupled to the first end portions of the one or more deformable tangs and defining a closed position wherein the latch urges first end portions inwardly parallel to the center portion thereby urging the one or more engagement portions into engagement with the one or more projecting portions and an open position wherein the latch urges the first end portions outwardly thereby urging the engagement portions out of engagement with the one or more projecting portions. 2. The equipment container of claim 1, wherein the interior surface of the lid defines a curved portion and the bracket secured to the lid defines a curved surface offset from the curved portion, the deformable tang passing between the curved portion and curved surface. 3. The equipment container of claim 2, wherein each curved pathway of the one or more curved pathways defines a first path portion and a second path portion, the second path portion being closer to a lower edge of the lid than the first path portion and being offset further from the lower edge of the lid than the first path portion. 4. The equipment container of claim 1, wherein the second end portion is angled with respect to the middle portion of each deformable tang when undeformed such that the engagement portions of the one or more deformable tangs are biased away from the one or more projecting portions when the latch is in the open state. 5. The equipment container of claim 1, wherein the latch further comprises: a rotatable handle rotatably coupled to the center portion; a drive gear coupled to the rotatable handle; a driven gear engaging the drive gear; a linkage assembly having first links pivotally coupled to the driven gear and second links each having first link end portions pivotally coupled to the respective first links and second link end portions each coupled to the first end portion of one of the one or more deformable tangs such that rotation applied to the rotatable latch in a first direction draws the engagement portion toward the lid and rotation applied to the rotatable latch in a second direction opposite the first direction urges the engagement portion outwardly from the lid. 6. The equipment container of claim 5, wherein the latch further comprises: a cam assembly including a plurality of sloped surfaces configured to guide a respective plurality of cam followers coupled to the linkage assembly, the driven gear defining a central aperture, the cam assembly being positioned within the central aperture. 7. A method comprising: providing a base portion forming a containment space to receive equipment, the base portion defining one or more projecting portions; placing a lid over the base portion, the lid including a center portion; providing one or more deformable tangs each having a first end portion, an arcuate-shaped slider and an engagement portion on a second end portion, the arcuate-shaped slider being between the first and second end portions; one or more brackets coupled to the lid, each bracket defining a curved pathway between the each bracket and an interior surface of the lid, each of the one or more deformable tangs passing through the curved pathway defined by one of the one or more brackets; and urging the first end portions in an inward direction thereby drawing the arcuate-shaped slider through the curved pathway, resulting in the second end portions being urged in an upward direction perpendicular to the inward direction thereby urging the one or more engagement portions into engagement with the one or more projecting portions. 8. The method of claim 7, wherein urging the deformable tangs inwardly effective to urge the one or more engagement portions into engagement with the one or more projecting portions comprises: providing a latch coupled to the first end portions of the one or more deformable tangs and defining a closed position wherein the latch urges the one or more engagement portions into engagement with the one or more projecting portions and an open position wherein the latch urges the deformable tangs out of engagement; and urging the latch from the open state to the closed state. 9. The method of claim 7, wherein the interior surface of the lid defines a curved portion and each bracket of the one or more brackets defines a curved surface offset from the curved portion, the deformable tang passing between the curved portion and curved surface. 10. The method of claim 9, wherein each bracket of the one or more brackets and the interior surface of the lid define a first path portion and a second path portion, the second path portion being closer to a lower edge of the lid than the first path portion and being offset further from the lower edge of the lid than the first path portion. 11. The method of claim 7, wherein: the projecting portions are inwardly projecting portions; the second end portion is angled with respect to the middle portion of each deformable tang when undeformed such that the engagement portions of the one or more deformable tangs are biased inwardly from the rim portion when protruding outwardly from the guide; and urging the deformable tangs inwardly effective to urge the one or more engagement portions into engagement with the one or more projecting portions further comprises urging the second end portions of the one or more deformable tangs between the interior surface of the lid and one of the brackets of the one or more brackets effective to urge the engagement portions outwardly and out of engagement with the one or more projecting portions. 12. The method of claim 7, further comprising providing: a rotatable handle rotatably coupled to the center portion; a drive gear coupled to the rotatable handle; a driven gear engaging the drive gear; a linkage assembly having first links pivotally coupled to the driven gear and second links each having first link end portions pivotally coupled to the respective first links and second link end portions, the first end portions of the one or more deformable tangs each coupled to the second link end portion of one of the second links such that rotation applied to the rotatable latch in a first direction draws the engagement portion toward the rim portion and rotation applied to the rotatable latch in a second direction opposite the first direction urges the engagement portion outwardly from the rim portion; wherein urging the deformable tangs inwardly effective to urge the one or more engagement portions into engagement with the one or more projecting portions comprises rotating the rotatable handle in the first direction. 13. The method of claim 12, wherein the latch further comprises: a cam assembly including a plurality of sloped surfaces configured to guide a respective plurality of cam followers coupled to the linkage assembly, the driven gear defining a central aperture, the cam assembly being positioned within the central aperture.
