Abstract: The present invention is a round-bottom flask support which comprises a base of honeycomb or honeycomb-like material flat on its lower surface and having a concave upper surface substantially complementary to the flask it is designed to support. The cross section of the base is preferably cylindrical and a cylindrical annular ring engaging the periphery of the base and upper surface can be provided for added dimension stability.The upper surface of the base preferably has a semi-spherical configuration produced by compression of the upper surface of the base toward the lower surface to create "pleats" in at least some cell walls. This provides an added mechanical lock at the cell nodes which reduces the tendency of the honeycomb to separate at the cell nodes and is of particular advantage where the honeycomb is subjected to high temperatures and the adhesive bond may be weakened.

Abstract: A flexible honeycomb structure formable into a non-planar contour comprising a cellular web of thin sheet material is disclosed. The cells in the web each have a cross section comprising three substantially congruent segments equally angularly disposed about a common center. Each such segment includes a non-linear portion intermediate to its ends, and is preferably in the shape of four contiguous sides of a hexagonal configuration for easy nesting of the cells. The present invention also provides alternate methods for forming the flexible honeycomb structure.
