Abstract

A battery container case comprises an ensemble storage section 21 having made and arranged therein plural holder holes 231 that hold individually respectively cylindrical batteries 10 upright in such a way that they are half fitted into the holder holes; an open/close lid 22 that covers the batteries in the ensemble storage section from above; and a restraint member 31 for each holder hole that hinders a respective one of the batteries from being taken out of the holder hole. Each restraint member 31 is fixed to the ensemble storage section in such a disposable manner that it is removable irreversibly.

Claims

1. A battery container case comprising:

an ensemble storage section having made and arranged therein plural holder holes that hold individually respectively cylindrical batteries in such a way that they are fitted up to a midway point of their length into the holder holes with the rest left outside; and

a restraint member for each of the holder holes that hinders a respective one of the batteries from being taken out of the holder hole,

wherein each of the restraint members is fixed to the ensemble storage section in such a disposable manner that it is removable irreversibly and thereby has a seal function to identify used/unused of a respective one of the batteries.

2. The battery container case according to claim 1, wherein the restraint members are arranged and fixed in such a way as to cover electrode terminals of the cylindrical batteries respectively.

3. The battery container case according to claim 1, wherein the ensemble storage section has made and arranged therein plural holder holes that hold the cylindrical batteries upright respectively.

4. The battery container case according to claim 1, wherein the ensemble storage section is formed by a rectangular box having a top panel, a bottom panel, and side panels, and the top panel has openings of the holder holes in plurality made and arranged therein, and the bottom panel has formed and arranged therein concaves to position bottoms of the cylindrical batteries half fitted into the holder holes.

5. The battery container case according to claim 1, further comprising:

an open/close lid that covers the batteries in the ensemble storage section.

6. The battery container case according to claim 5, wherein the open/close lid is a transparent lid.

7. The battery container case according to claim 5, wherein a single resin thin board is bent and assembled into the ensemble storage section and the open/close lid.

8. The battery container case according to claim 7, wherein the resin thin board is bent into the ensemble storage section and the open/close lid, and by fitting together cylindrical convexes and cylindrical concaves formed in the resin thin board, surface panels of the container case bent orthogonal to each other are joined together, thereby assembling the resin thin board into a predetermined solid structure, and wherein at least one of the surface panels, on which pressing force is exerted in a direction along its surface when fitting together the cylindrical convexes and concaves, is selectively reinforced with a rib formed along an acting direction of the pressing force.

9. The battery container case according to claim 1, wherein the restraint member is transparent and shaped like a cap that covers part, outside the holder hole, of the cylindrical battery held in a half-fitted state in the holder hole.

10. The battery container case according to claim 4, wherein the restraint members are formed like caps from the top panel by selectively expanding it, and in association with the forming, the openings of the holder holes are made, and annular parts along the edges of the openings are formed as thinner or notched portions easy to break.

11. The battery container case according to claim 9, wherein the top of the cap-shaped restraint member has a slit that surrounds half-circularly a convex electrode terminal of the cylindrical battery.

12. The battery container case according to claim 1, wherein the restraint member is a tap-like sheet and straddles the top of the cylindrical battery held in a half-fitted state in the holder hole, and both its ends are fixed to the ensemble storage section in such a way that it is irreversibly removable.

13. The battery container case according to claim 1, wherein the restraint member is a cross-shaped sheet and the intersection of the cross covers the top of the cylindrical battery, and each end of the cross is fixed to the ensemble storage section in such a way that it is irreversibly removable.

14. The battery container case according to claim 1, wherein the restraint member is formed such that at least its part takes on a different color and/or pattern from those of its neighbors.
