FIG. 3 shows a perspective view of a main part of a dropper cap with unevenness formed on the side surface and treated to prevent rolling, and a cross-sectional view of a pipette and a dropper mounting portion. FIG. 4 shows a perspective view of the essential parts of a dropper cap with longitudinal grooves formed on the side surface and treated to prevent rolling, and a cross-sectional view of the pipette and dropper mounting portion. FIG. 5 shows a state in which a dropper cap, which has been treated to prevent rolling, is attached to a pipette and a dropper, and is left stationary on a laboratory bench. FIG. 6 is a side view of a conventional dropper cap and a sectional view of the dropper attachment part. FIGS. 7 and 8 show a conventional dropper cap with a pipette and a dropper attached to it, or a dropper cap alone placed on a laboratory bench. A...Outer diameter of the liquid reservoir of the pipette or dropper,
B... Pipette of the dropper cap, outer diameter of the dropper attachment part, 1... Flat part, 2... Curved part, 3... Uneven part, 4... Vertical groove, 5... Pipette, dropper, 6... Liquid Bad part.

Claims
