<p>PROBLEM TO BE SOLVED: To improve operativity of opening and closing operation of a lid, realize easy replacement to various devices and omit a space for a lid, by providing a hinge means for connecting a container and a lid rotatively. SOLUTION: An outer box 1, an alignment inner box and a lid 7 are incorporated in a fine board container and it is further provided with a hinge means 9 for connecting the outer box 1 and the lid 7 rotatively. The hinge means 9 has a first fitting rib group 10 and a second fitting rib group 11 in the outer box 1 and has a supporting rib group 12 in the lid 7. A columnar shaft 13 is formed in the supporting rib group 12. The first rib group 10 has a pair of first fitting ribs 14, 14A opposing mutually, and the first fitting ribs 14, 14A are formed to project integrally keeping a space in a side of a bent part of a rear wall 5 of the outer box 1. As a result, it is possible to open and close the lid 7 readily by one hand or by an automatic machine, to improve operativity and to realize easy replacement to an automatic machine.</p> |
