Patent ID: 7975845

Claim:
A container for holding a measuring device comprising: an elongated conduit including an interior cavity dimensioned to fully encompass the measuring device; a polymeric liner dimensioned to fit within the interior cavity, the polymeric liner extending a length of the interior cavity of the elongated conduit and including at least four resilient contact surfaces disposed on an outer surface of the liner, and the resilient contact surfaces arranged to uniformly engage a portion of an interior surface of the elongated conduit sufficient to maintain the polymeric liner within the interior cavity; and, a head cap coupled to a first longitudinal end of the elongated conduit, the head cap including: a generally trapezoidal side profile; a frontal cross sectional dimension greater than a frontal cross sectional dimension of the elongated conduit; an aperture in communication with the interior cavity, the aperture dimensioned to receive the measuring device therethrough; and, a door coupled to a frontal face of the head cap and dimensioned to laterally span the aperture when disposed in a closed position; and, an end cap coupled to a second longitudinal end of the elongated conduit; and a counterforce element disposed within the elongated conduit, the counterforce being coupled to the end cap and aligned to generate a longitudinal counterforce on the measuring device when an end of the measuring device compressively engages the counterforce element.
