The closure device (121) includes interlocking fastening strips (130, 131) and a slider (132). The fastening strips include a flange portion (163, 153) that engages a separator (143) on the slider. The flange portion angles inwardly toward the separator. The flange portion (163, 153) is altered at the closing end of the fastening strips to prevent the slider from opening the fastening strips at the closing end. The flange portion may be altered by flattening (172, 174) the flange portion. |
