Claim Text:
1. A constant force compression tool for measuring a given volume of a compressible material at a desired compressive pressure, the tool comprising: a plunger having a first end and a second end in opposition to one another, the first end having a surface configured to compress the compressible material; a handle having a passageway receiving the plunger between the first end and the second end; a biasing member in communication with the plunger and the handle so as to provide a biasing force between the plunger and the handle; and a retaining element in communication with the plunger and the handle so as to prevent the plunger from disengagement with the handle; wherein the plunger, the handle, and the biasing member are coordinated with a measurement tube to (1) provide a desired compressive pressure to the compressible material, and (2) indicate a given volume of the compressible material.
