CA 2563633

A vial (10) and a level (80) including such vial are disclosed. The vial has a body (20) that forms a cavity (30) and has first and second ends (21, 22), a midpoint (23), interior and exterior surfaces, a pair of marker rings (41, 42) extending around the body, and first and second dark-colored bands (61, 62) around the body near the first and second ends, respectively. A liquid (53) and bubble (50) of gas (52) are within the cavity. The gas-liquid interface (51) is substantially enhanced in visibility, with the result that the bubble and its relationship to the marker rings are more easily seen.

Une fiole (10) et un niveau (80) comprenant une telle fiole. La fiole présente un corps (20) formant une cavité (30) ainsi que des première et seconde extrémités (21, 22), un point intermédiaire (23), des surfaces interne et externe, une paire d'anneaux marqueurs (41, 42) entourant le corps, et des première et seconde bandes à couleurs obscures (61, 62) entourant le corps à proximité des première et seconde extrémités. Un liquide (53) et une bulle (50) de gaz (52) se trouvent dans la cavité. L'interface gaz-liquide (51) est sensiblement améliorée en termes de visibilité, ce qui se traduit par une meilleure vision de la bulle et de son rapport avec les anneaux marqueurs.
