1 Claim. (Cl. 15-566)
This invention relates to a dauber for use in applying
circular con?guration.
The foam rubber 20 is in the form .of a disk which is
normally spaced from the disk shaped upper edge of the
valve member 24, but which is adapted to be moved into
engagement with the valve member 24 when the dauber

The retaining ring 14 is molded of polyethylene or
