The ornamental design for a bobeche, as shown and described.
FIG. 1 is a perspective view of a bobeche showing my new design;
FIG. 2 is a side elevational view thereof, the opposite side being a mirror
image;
FIG. 3 is a bottom plan view thereof;
FIG. 4 is a cross-sectional view thereof as taken along 4--4 of FIG. 3.
The bobeche is transparent; however all elements which would normally
appear through the side of the bobeche in FIG. 1 are omitted for ease of
illustration and clarity of disclosure.
