Patent ID: 8336711

Claim:
A case for housing a rolled object which has a core jutting from both end portions of the rolled object, comprising: end face wall components which support the core so as to horizontally suspend the rolled object; and side wall components which connect the end face wall components with each other and are provided opposite one another along a circumferential surface of the rolled object which when housed is placed in a horizontal direction, each of the side wall components including: a planar wall portion which is vertically disposed; and a jutting portion which is formed horizontally across the wall portion at a vertical central portion of the wall portion and which has a surface facing when the rolled object is housed, the circumferential surface of the rolled object without being in contact with the circumferential surface, while the surface of the jutting portion is disposed so as to be able to contact the circumferential surface of the rolled object when the case is deformed by an external force, wherein a plane defined by the surface of the jutting portion on each of the side wall components defines an intersection with a core horizontal plane which includes the axis of the core of the rolled object when housed, the surface including an upper region surface and a lower region surface each of which is extending from said intersection and is inclined away from the vertically-disposed planar wall portion to face the circumferential surface of the rolled object, wherein each of the side wall components is arranged so that a line connecting a vertical upper end of the upper region surface and a vertical lower end of the lower region surface intersects with the core horizontal plane at a position closer to the center of the rolled object than the outer circumferential surface of the rolled object, wherein each of the side wall components is assembled by separable structural components which are symmetrically provided in up and down directions about the core horizontal plane, and wherein each of the separable structural components is folded in a manner that forms: a flat plate portion constituting a part of the vertically-disposed planar wall portion; a surface portion constituting one of the upper region surface and the lower region surface of the jutting portion; and a surface supporting portion which connects the flat plate portion and the surface portion.
