Package body for ceramic separation membrane and packaged item

A package body for ceramic separation membranes, comprising:

• a packaging box which stores a plurality of ceramic separation membranes in parallel in a width direction and a height direction;
• and
• at least first and second partition packs, wherein
• each of the first and second partition packs has a thickness equal to or larger than a thickness of each of the ceramic separation membranes, and has a plurality of storing parts, with intervals therebetween in the width direction, which are rectangular through holes of a simple-shaped projection shape of the ceramic separation membrane and penetrating from the upper surface to the bottom surface of the partition packs, and the packaging box stores the at least first and second partition packs stacked in the height direction with the plurality of storing parts arranged in the width direction in a staggered manner,
• the ceramic separation membrane is a cylindrical separation membrane having a diameter of D, and each of the intervals between the plurality of storing parts arranged substantially parallel to the width direction is D/2 or more and D or less, and
• the partition packs are disposed stacked vertically, in which a lower end of the storing parts of the partition packs in an upper position is at a higher position than an upper end of the storing parts of the partition packs in a lower position,
• wherein n is the number of storing parts of the first partition pack placed at a bottom of the packaging box, and n−1 is the number of storing parts of the second partition pack placed on the first partition pack,
• wherein center lines of the storing parts of the first partition pack and center lines of the storing parts of the second partition pack are arranged at substantially equal spacing in the width direction,
• wherein center lines of the intervals of the first partition pack and center lines of the intervals of the second partition pack are arranged at substantially equal spacing in the width direction, and
• wherein the center lines of the storing parts in the first partition pack are arranged to align with the center lines of the intervals of the second partition pack between the storage parts of the second partition pack such that openings of the rectangular through holes in the first partition pack overlap with openings of the rectangular through holes in the second partition pack along a longitudinal direction.
