An applicator has reservoir for fluid and a supply passage. A valve in the passage has a seat and a member movable between closed and open positions. A spring biases the member toward its closed position. An elongated nib is mounted in the supply passage and has an end extending from the passage, the nib engaging the member so that the member moves to its open position. An adapter has a portion for holding a pad that has at least one dimension elongated transversely to the nib. The adapter includes an engagement portion with a cavity for detachably receiving an end of the reservoir, the cavity having a depth so that it engages the nib when the end of the reservoir is detachably received in the cavity to apply pressure on the nib to move the member to its open position.
