The packaging construction includes an accommodation case including a bottom plate, and side plates located on outer edges of the bottom plate; a first tray having first recesses into which one end portions of the batteries are fitted, placed immediately above the bottom plate, and fixed to the accommodation case; and a second tray having second recesses into which the other end portions of the batteries are fitted, and placed above the first tray. The batteries are held so as to be fitted to the first and second trays and such that each adjacent pair of the batteries are apart from each other. A portion of a bottom of each first recess facing a corner portion of the one end portion of a corresponding one of the fitted batteries protrudes outward to be apart from the corner portion. ## Claims ### Claim 1 A packaging construction for packaging a plurality of columnar batteries, the packaging construction comprising: an accommodation case including a bottom plate, and side plates located on outer edges of the bottom plate; a first tray placed immediately above the bottom plate and fixed to the accommodation case; and a second tray placed above the first tray, wherein the first tray has a plurality of first recesses into which one end portions of the columnar batteries are fitted, and is fixed to the accommodation case such that bottoms of portions of the first tray corresponding to the first recesses face the bottom plate, the second tray has a plurality of second recesses into which the other end portions of the columnar batteries are fitted, the columnar batteries are held such that the one end portions of the columnar batteries are fitted into the first recesses of the first tray, the other end portions of the columnar batteries are fitted into the second recesses of the second tray, and each adjacent pair of the columnar batteries are apart from each other, and a portion of a bottom of each first recess facing a corner portion of the one end portion of a corresponding one of the fitted columnar batteries protrudes outward to be apart from the corner portion. ### Claim 2 (depends on 1) The packaging construction of claim 1, wherein a depth of each first recess is greater than or equal to 5% of a height of each columnar battery and equal to or less than 50% of the height of the columnar battery. ### Claim 3 (depends on 1) The packaging construction of claim 1, further comprising: a retaining member placed on the second tray. ### Claim 4 (depends on 1) The packaging construction of claim 1, wherein one of electrode terminals of each columnar battery includes a protrusion, and the first or second recesses into which the end portions of the columnar batteries each including the one of the electrode terminals are fitted each include an indentation that keeps a surface of the first or second recess apart from the one of the electrode terminals when a corresponding one of the end portions has been fitted into the first or second recess. ### Claim 5 (depends on 1) The packaging construction of claim 1, wherein each first recess is tapered so as to be narrowed from an opening to a bottom of the first recess. ### Claim 6 (depends on 5) The packaging construction of claim 5, wherein a taper angle of each tapered first recess is greater than or equal to one degree and equal to or less than 20 degrees. ### Claim 7 (depends on 1) The packaging construction of claim 1, wherein each second recess is tapered so as to be narrowed from an opening to a bottom of the second recess. ### Claim 8 (depends on 7) The packaging construction of claim 7, wherein a taper angle of each tapered second recess is greater than or equal to one degree and equal to or less than 20 degrees. ### Claim 9 (depends on 1) The packaging construction of claim 1, wherein a distance between the first and second trays is greater than or equal to 30% of a height of each columnar battery and equal to or less than 90% of the height of the columnar battery. ### Claim 10 (depends on 1) The packaging construction of claim 1, wherein the accommodation case is in the form of a rectangular box, and is made of corrugated cardboard, and a core of the corrugated cardboard has flutes extending obliquely to edges of a corresponding one of rectangles forming the accommodation case. ### Claim 11 (depends on 1) The packaging construction of claim 1, wherein the first and second trays are made of plastic containing an anticorrosive.
