Container

A container, comprising:

• an accommodation member including a bottom surface member defining a bottom surface of an accommodation space and a side surface member defining a side surface of the accommodation space;
• and
• at least one protection member located in the accommodation space and having at least one receiving surface to be in contact with an object to be accommodated in the accommodation space,
• wherein the side surface member includes at least one cutout portion facing the accommodation space,
• wherein the at least one protection member includes an inner member including a receiving portion having the at least one receiving surface and also includes an outer member located between the inner member and the side surface member and fit to the inner member so as to be slidable in a certain direction crossing the bottom surface,
• wherein the inner member and the outer member included in the at least one protection member are located in the at least one cutout portion so as to be detachable in the certain direction independently,
• wherein in a state where the outer member is detached, at least a part of the inner member is retractable into a space in which the outer member was present before being detached,
• wherein the bottom surface member defines an xy plane, the side surface member defines an xz plane and a yz plane both perpendicular to the xy plane, and the accommodation space has four corners,
• wherein the at least one cutout portion includes cutout portions respectively facing at least two adjacent corners among the four corners of the accommodation space,
• wherein the at least one protection member includes protection members respectively located in the cutout portions respectively facing the at least two adjacent corners,
• wherein the at least one receiving surface includes two receiving surfaces respectively parallel to the xz plane and the yz plane,
• wherein the outer member is fit to the inner member so as to be slidable in a z direction,
• wherein the receiving portion of the inner member has a bottom surface in contact with the bottom surface member and parallel to the xy plane,
• wherein the inner member further includes a support portion formed adjacent to the receiving portion in a y direction and having a support surface parallel to the xz plane,
• wherein the support surface is in contact with a surface, of the outer member, parallel to the xz plane, and
• wherein a bottom surface, of the support portion, facing the bottom surface member and parallel to the xy plane is not in contact with the bottom surface member.
