Abstract
Disclosed herein is a children's ball pen for use in the home. The ball pen is made from a floor and sidewall of corrugated plastic sheets which are sonically welded together. Molded bottom anchors between the floor and sidewall together with rings hold resilient polymeric foam covered vertical posts in the desired upright position. A metal rod surrounds the top of the sidewall to give added rigidity and provide an anchor for the vertical post rings. A net and a top complete the ball pen and hold balls therein during play.
