A split dove-tail gasket channel structure includes a fir structure having a first external surface and a first edge plane substantially parallel to the first external surface, a first surface substantially perpendicular to the first edge plane, a second surface adjacent to the first surface and at an acute angle to the first edge plane, and a third surface adjacent to the second surface and at an acute angle to the first edge plane. A second structure has a second external surface and a second edge plane substantially parallel to the second external surface, a fourth surface substantially perpendicular to the second edge plane, a fifth surface adjacent to the fourth surface and at an acute angle to the second edge plane, and a sixth surface adjacent to the fifth surface and at an acute angle to the second edge plane. The first surface and the fourth surface are configured to complement one another, the second surface and the fifth surface are configured to complement one another and the third surface and the sixth surface are configured to oppose one another. A gasket is positioned between the third surface and the sixth surface to form the seal. In another embodiment, the sixth surface is positioned at an acute angle with respect to the fifth surface, creating a channel therebetween. Advantages of the invention include an upper structure and a lower structure that provide a good seal but with a smaller size and more consistent thickness than conventional structures.
