<p>PURPOSE:To obtain an inexpensive stooling bag molding material by folding and stacking one raw molding material to form upper, intermediate and lower layer parts and forming a glove-shaped part to the thin wall part formed by welding the intermediate and lower layer parts so as to be capable of pulling out the same by slight pressure. CONSTITUTION:A stooling bag molding material consists of upper and under surfaces formed from plastic colored thin blue. One raw molding material 1 is folded along folding lines 2a, 2b to be stacked to form an upper layer part (a), an intermediate layer part (b) and a lower layer part (c). A contour is formed by a thin wall part 5 formed by welding the intermediate layer part (b) and the lower layer part (c) along the folding line 2b and a glove means pulled out from the intermediate and lower layer parts (b), (c) by slight pressure is formed to the thin wall part 5. Further, the inlet 6 of the glove-shaped part is formed between the lower layer part (c) and the folding line 2a of the upper and intermediate layer parts (a), (b). The upper, intermediate and lower layer parts (a), (b), (c) are bonded at necessary parts 7, 8 along the folding lines 2a, 2b.</p> |
