<p>PROBLEM TO BE SOLVED: To easily reopen a resin-made case, without effecting an incorporated electronic part by forming a through-hole on the wall surface of a resin case using a heat bar, and inserting a voltage-applying terminal from the through-hole to apply voltage to a resistant heating element in the resin case inside, thereby fusing resin on a joint surface. SOLUTION: A heat bar 40 is abuttingly pressed to the opening part 14 of a battery case to drill a through-hole 13, and a place, on which the heat bar 40 abuts, is preferably near to both the end parts of an incorporated resistive heating element 20. A voltage-applying terminal is inserted into the through- hole 13, formed on the opening part 14 to be made abutting on the heating element 20, and voltage is applied to a fuse resin on a joint surface. Then, a cover 12 is separated from a case main body to open the battery case, because a force is applied in a separating direction in the case main body and a cover 12. A heating tip may be used for the through-hole 13 and is also integrally formed previously in forming the case, and voltage can be applied by using the thorough-hole 13.</p> |
