Abstract
A case has a center support and an open top. A central wall forms first and second major chambers with an aperture there between. The case has a pair of butterfly doors forming minor chambers. Hinges couple the butterfly doors to the central support adjacent to the top. A sealing assembly is an injection molded, one piece seal formed of first and second sealing rings joined together along an intermediate extent. An annular recess is formed in the case at the open top around each major chamber. The recesses receive and support the sealing rings. Recipient regions are provided in the butterfly doors around the minor chambers for contacting the sealing rings when the butterfly doors are in the closed orientation. A handle assembly has a handle and depending components. The depending components include a projection with keyways. A recipient sleeve supports the projection. The handle assembly has keys in the aperture of the center support.
