<p><P>PROBLEM TO BE SOLVED: To prevent a blocking phenomenon between molded lids 10 each formed with an inward-convex swelling part 20 on its skirt 16 which are stacked in multiple stages, to thereby smoothly take out the upper molded lid from the stacked-lid group, and to reduce a stack height of the molded lids 10 stacked in multiple stages. <P>SOLUTION: The molded lid 10 at least includes: a horizontal flange 15; and the skirt 16 formed on an outer edge of the horizontal flange 15. The skirt 16 has a vertical wall 17 extending downward in a vertical direction from the outer edge of the horizontal flange 15, and the inward-convex swelling part 20 is formed on a location separated from the horizontal flange 15, on part of the vertical wall 17. Preferably, a lower face part 22 and a tilting wall 18 of the swelling part 20 totally have a cross-section of an upward convex arc. When the molded lids 10 are stacked, a corner 23 formed between the outer edge of the horizontal flange 15 and the vertical wall 17 of the lower molded lid 10 line-contacts the lower face part 22 of the swelling part 20 and the tilting wall 18 of the upper lid 10. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
