includes a second reinforcing rib 23 which extends upwardly from control support member 14 to strengthen the hook and to resist twisting or flexure of the hook 15 when the garment hanger is in use flanges 22 23 join with similarly defined upper flange 24 defined by central support member 14 central support member 14 includes upper and lower flanges 24 25 and a center medial flange 26 which serves to stiffen the hanger by choosing a relatively resilient plastic material for the hanger 11 and a relatively stiff plastic material for the cap the snap fit engagement can be made relatively permanent since once the index coded cap is secured by snap fit engagement barbs 18 it is necessary to bend or flex the side walls 17a 17b beyond barbs 18 before the cap can be removed the stiffness of the plastic material used to form the cap thereby determines the degree of difficulty one encounters in removing the cap further the fit and cooperation of the flat edge 17c of the cap and the horizontal flange 21 makes it difficult to insert a screw driver or other means with which to pry the side walls apart for removal of the cap as illustrated in fig1 6 the index cap includes several indexing features the cap is color.
