Abstract:
A tube for holding an object, the tube comprising:a cylindrical body with an interior surface and an exterior surface, the interior surface being adapted to allow placement of the object;a number of rails and a number of channels formed in the exterior surface, approximately half of the rails and channels having a first width and half of the rails and channels having a second width, the second width being larger than the first width; both the rails and channels having side surfaces that are back-cut, portions of the rails and channels being cross-sectionally sized and shaped similarly to each other to permit the tube to matingly engage another tube; anda first end and a second end, the rails and channels extending between tube ends and being formed alternatingly about the tube exterior surface in an orientation parallel to the tube longitudinal axis; the smaller channels being interspaced between the larger rails and the larger channels being interspaced between the smaller rails;whereby to engage the tube with another tube, the rails of the tube are slid into the correspondingly-sized channels of the other tube, their mutually back-cut side surfaces maintaining their engaged relationship.
