PROBLEM TO BE SOLVED: To provide a sealing packaging case 10, which comprises a pair of front and back lids 11, 26 having respective oblong ring-shaped peripheries 12, 27 of almost same shape and size that form center hollow top surfaces on which thin silicone rubbers 16, 31 are stretched, where the linear contacting edges of the front and back lids 11, 26 are coupled via a bendable belt hinge 25 so that various small articles can be sealed between silicone rubbers 16, 31 inside the case 10 opening and closing freely. SOLUTION: On the back lid 11, an almost L-shaped hardened periphery 17 made of the silicone rubber 16 is inserted in a ring-shaped groove 14 on the upper surface of the rectangular ring-shaped frame 12 to be fitted along the bottom and inner side face of the groove 14, and a ring-shaped fixing frame 20 having a periphery slightly smaller in radius than the outer inner periphery of the groove 14 and almost identical in shape with the periphery 17 is fitted on the periphery 17 to be fixed. On the inner surface of the front lid 26 almost identical with the back lid 11 in shape and size, a ring-shaped stripe projection 34 to be fitted into a gap 19 encircling the groove 14 is formed. The lids 11, 26 are placed next to each other, and their adjacent linear side edges are coupled via the belt-shaped hinge 25 to enable the case 10 to open and close freely. COPYRIGHT: (C)2004,JPO
