Abstract
The present invention relates to a method of attaching a flexible plastic component to a rigid plastic component. The present technique can be used for such purposes as retrofitting suction cups to rigid plastic hollow legs such as may be provided to a children's bathtub seat. The flexible plastic component is attached to the rigid plastic component by use of the following procedure: (a) a passage is provided in the rigid component; (b) an extension is contoured to slidably engage the passage in the rigid plastic; (c) the extension is provided with one or more indentations; (d) the rigid plastic inserts are contoured to fit the indentation in the extensions; (e) the inserts are placed in the indentations; (f) the rigid plastic inserts are wet with a bonding liquid; (g) and finally the extension is inserted into the passage in the rigid plastic.
