Leakage past the sliding dam structure in an adjustable measuring spoon or scoop is stopped by extending an edge-mounted seal into the space between the dam structure and the side flange of the slider to which the dam structure is attached, or by providing thin, flexible curved edges to the dam structure to increase the area of sealing contact with the inside walls of the bowl in which the dam structure slides. Increased surface contact is provided due to the angle that the dam edges make with the inner bowl surface areas. |
