) with a size of 1 cm×6 cm was bonded to the central portion of the protective sheet 13 in the axis line direction D and the protective sheet 13 was fixed to the electrophotographic photosensitive member 11. As shown in FIG. 4, coupling portions 12 were attached to one end portion and the other end portion of the electrophotographic photosensitive member 11 in the axis line direction D and a packaged object 100 according to Example 1 was obtained. The packaged object 100 is conveyed in the state of the package member 300A.

As shown in FIG. 6, the package member 300A includes the packaged object 100 and an accommodation container 200A. Hereinafter, the description will be given assuming that when the packaged object 100 is accommodated in the accommodation container 200A, a direction of the packaged object 100 along the axis line direction D (see FIG. 4) is a left-right direction X, a direction parallel to the horizontal direction and orthogonal to the left-right direction X is a front-back direction Y, and a direction orthogonal to the left-right direction X and the front-back direction Y is an up-down direction Z.

The accommodation container 200A accommodates a plurality of packaged objects 100. The accommodation container 200A is configured to have a substantially rectangular parallelepiped shape. The accommodation container 200A is made of, for example, polyethylene terephthalate resin (PET) and accommodates ten packaged objects 100. Accordingly, the accommodation container 200A ensures cold resistance, water resistance, and electrical insulation. The accommodation container 200A includes a container part 210A and a lid part 220A.

The container part 210A accommodates the entire plurality of packaged objects 100 along the front-back direction Y. Specifically, the container part 210A accommodates the entire plurality of packaged objects 100 so that the plurality of packaged objects 100 is aligned in parallel. The container part 210A includes support portions 211A, a bottom wall 212A, a front wall 213A, a rear wall 214A, a left wall 215A, and a right wall 216A. Shorter walls of the front, rear, left, and right walls will be sometimes described as the front wall 213A and the rear wall 214A. A wall on the left side when facing the rear wall 214A will be sometimes described as the left wall 215A.

The bottom wall 212A is a substantially rectangular wall portion that faces the lid part 220A and is orthogonal to the up-down direction Z. The front wall 213A extends upwards from one end portion of the bottom wall 212A in the front-back direction Y and is orthogonal to the front-back direction Y. The rear wall 214A extends upwards from the other end portion of the bottom wall 212A in the front-back direction Y and faces the front wall 213A. The left wall 215A extends upwards from one end portion of the bottom wall 212A in the left-right direction X and is orthogonal to the left-right direction X. The right wall 216A extends upwards from the other end portion of the bottom wall 212A in the left-right direction X and faces the left wall 215A.

The support portions 211A support end portions of the packaged object 100 in the left-right direction X. The left support portions 211A are arranged on a side of the left wall 215A, which faces the right wall 216A, and the right support portions 211A are arranged on a side of the right wall 216A, which faces the left wall 215A. The left support portions 211A and the right support portions 211A respectively support one coupling portion 12 and the other coupling portion 12 of the packaged object 100. Accordingly, the end portions of the protective sheet 13 can be prevented from bending in the package member 300A that accommodates the plurality of packaged objects 100.

The left support portions 211A have upper surface portions that are substantially arcuate in cross-section. The upper surface portions are capable of being held in face contact with the lower portions of the coupling portions 12. The left support portions 211A project toward the right wall 216A from the left wall 215A. The length of the left support portions 211A in the left-right direction X that protrude toward the right wall 216A is shorter than the length of the coupling portions 12 in the left-right direction X. Accordingly, the end portions of the protective sheet 13 can be further prevented from bending. The right support portions 211A are similar to the left support portions 211A.

The lid part 220A closes the opening of the container part 210A. The plate-shaped lid part 220A closes the opening of the container part 210A in which the ten packaged objects 100 according to Example 1 are accommodated. A package member 300A according to Example 1 was thus obtained.

Example 8

As shown in FIG. 3, an electrophotographic photosensitive member 11, which was an organic photosensitive member with a length L1 of 343 mm in the axis line direction D and an outer shape of 30.2 mm, was prepared. As shown in FIG. 5, a protective sheet 13, which was rectangular black paper with a length L2 of 332 mm in the axis line direction D (see FIG. 3), a length of 150 mm in the direction orthogonal to the axis line direction D, and paper density of 80 g/m², was prepared. A center position C2 of the protective sheet 13 in the axis line direction D was aligned with a center position C1 of the electrophotographic photosensitive member 11 in the axis line direction D and the protective sheet 13 was wrapped around the electrophotographic photosensitive member 11 without loosening. An adhesive tape 14 (see FIG. 4) with a size of 1 cm×6 cm was bonded to the central portion of the protective sheet 13 in the axis line direction D and the protective sheet 13 was fixed to the electrophotographic photosensitive member 11. As shown in FIG. 4, coupling portions 12 were attached to one end portion and the other end portion of the electrophotographic photosensitive member 11 in the axis line direction D and the packaged object 100 according to Example 8 was obtained. The packaged object 100 is conveyed in the state of the package member 300B. Hereinafter, when the package member 300A and the package member 300B may be collectively referred to as package members 300.

As shown in FIG. 7, the package member 300B includes the packaged object 100 and an accommodation container 200B.

The accommodation container 200B accommodates the plurality of packaged objects 100. The accommodation container 200B is made of, for example, polypropylene resin (PP) and accommodates ten packaged objects 100. Accordingly, even though the accommodation container 200B is inexpensive, the accommodation container 200B ensures heat resistance and chemical resistance. The accommodation container 200B includes a container part 210B and a lid part 220B.

The container part 210B accommodates lower halves of the plurality of packaged objects 100. Specifically, the container part 210B accommodates the lower halves of the plurality of packaged objects 100 so that the plurality of packaged objects 100 is aligned in parallel in the front-back direction Y. The container part 210B includes support portions 211B, a front wall 213B, a rear wall 214B, a left wall 215B, and a right wall 216B.

The support portions 211B support end portions of the packaged objects 100 in the left-right direction X. The support portions 211B are configured to have wavy cross-sections. The support portions 211B have upper surface portions that are substantially arcuate in cross-section. The upper surface portions are capable of being held in face contact with the lower portions of the coupling portions 12.

The front wall 213B extends upwards from one end portions of the support portions 211B in the front-back direction Y. The front wall 213B is orthogonal to the front-back direction Y. The rear wall 214B extends upwards from the other end portions of the support portions 211B in the front-back direction Y. The rear wall 214B faces the front wall 213B. The left wall 215B extends upwards from one end portions of the support portions 211B in the left-right direction X. The left wall 215B is orthogonal to the left-right direction X. The right wall 216B extends upwards from the other end portions of the support portions 211B in the left-right direction X. The right wall 216B faces the left wall 215B.

The lid part 220B accommodates upper halves of the plurality of packaged objects 100. Specifically, the lid part 220B accommodates the upper halves of the plurality of packaged objects 100 so that the plurality of packaged objects 100 is aligned in parallel toward the front-back direction Y. By aligning the container part 210B with the lid part 220B, the accommodation container 200B accommodates the plurality of packaged objects 100. A package member 300B according to Example 8 was thus obtained.
