section 16 and head mounting section 20. Janssen teaches that
the handle member 14 is preferably constructed of a
lightweight, durable plastic, however it may be constructed of
wood or other suitable material. Further, the handle member
14 is preferably a molded material of sufficient strength,
structure, and shape to provide support and control for a
mounted head member designed for the application of paint and
other coating materials. The head mounting section 20 is a
flat plate of generally rectangular shape containing laterally
extending serrations 24 designed to engage the mounted head
member 30. The circumferential skirt 22 permits separation of
handle gripping section 16 from head mounting section 20. 2
As shown in Figure 2, when head member 30 is fully mounted on
head mounting section 20, the laterally extending serrations
24 of head mounting section 20 engage the cavity defining
surfaces to retain head member 30 on handle member 14.
Additionally, Janssen discloses that in order to
provide optimum gripping of the brush by a user, the elongate
gripping section 16 should be generally about 10 cm in length
