Abstract:
A gauge system for measuring internal diameters of tubular openings, comprising:a support shaft; a surface coupled to an end of the support shaft, the surface supports a container in a position wherein the container comprises a tubular neck having an opening with a first predetermined inner diameter and a second predetermined inner diameter; a measuring rod having a tapered end with a plurality of reference markings, wherein the tapered end of the measuring rod is adapted to pass through the opening of the tubular neck; and a holder member comprising: a first end; an aperture positioned at the first end, said aperture being adapted to receive the measuring rod, to allow the first measuring rod to move relative to a vertical axis of the measuring rod, and to allow the measuring rod to move from a first initial position into a second extended position; and a pivot portion to pivotally mount the holder member on a second end of the support shaft so as to allow a user to move the holder member about the support shaft and relative to the surface and to position the measuring rod above the opening of the tubular neck of the container such that when the measuring rod is urged into the second extended position, the measuring rod moves into the tubular neck thereby allowing the user to determine the second inner diameter of the tubular neck with respect to the reference markings.
