Abstract: The apparatus includes a bellows member formed by a pleated wall. An interior cavity is located inside of the bellows member. The wall has first and second openings that communicate with the interior cavity. A lip surrounds the first opening. To use the apparatus, the elastomeric covering is inserted, closed end first, into the interior cavity. The open end of the covering is folded onto the lip at the first opening so as to form a seal. The bellows member is contracted to expel air through the second opening. Then, the second opening is closed and the bellows member is expanded, causing the covering to expand. The body member is inserted into the interior of the covering. The second opening is then opened, allowing the covering to contract onto the body member.
