the hollow member has an end that faces the second opening and is configured to discourage capillary flow around the end, and wherein:
the hollow member defines an axis;
an outer wall of the hollow member at the end of the hollow member has a first wall thickness measured in a direction perpendicular to the axis;
a part of the hollow member arranged closer to the first end of the housing than the end of the hollow member has a second wall thickness measured in a direction perpendicular to the axis; and
the first wall thickness is smaller than the second wall thickness.
