Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, the interest in stationery in general has been increasing again, and analog writing instruments such as fountain pens, glass pens, and high-quality ballpoint pens have been gaining popularity. When carrying these writing instruments, a pen holder that can securely hold the writing instruments is desired in order to prevent the writing instruments from rubbing against each other and being damaged. On the other hand, in order to satisfy the desire to enjoy looking at the writing instruments even when they are held in the pen holder, it is also desired to reduce the portion of the pen holder that covers the writing instruments as much as possible and improve the visibility of the held writing instruments. <0​​​​​​​​​A first aspect of the present disclosure is a pen holder for holding a plurality of writing instruments arranged in the width direction, comprising: a support surface portion having a support surface for supporting the writing instruments; and a second holding portion disposed on the support surface and gripping the sides of the writing instruments to restrict their displacement in the width direction, wherein the second holding portion has a plurality of second cylindrical portions through which the writing instruments cannot be inserted, and the second cylindrical portions abut against the sides of the writing instruments to restrict their displacement in the width direction.

[0007] A second aspect of this disclosure is a pen case equipped with a pen holder according to the first aspect. [Effects of the Invention]

[0008] According to this disclosure, the second holding part can prevent damage from friction with other adjacent writing instruments, and can also hold the writing instrument with a part of it exposed, thus providing excellent visibility of the held writing instrument.

MODE FOR CARRYING OUT THE INVENTION

[0010] (First Embodiment) The pen holder 10 of this embodiment shown in Figure 1 holds multiple writing instruments 12, such as ballpoint pens, fountain pens, glass pens, retractable pencils, and pencils, arranged on a predetermined support surface 14. The pen holder 10 is used to hold writing instruments 12 by being attached to, for example, a pen case 40, a notebook cover, a notebook binding sheet, or a file cover. In the illustrated example, the pen holder 10 is shown as being able to hold six writing instruments 12, but this embodiment is not limited to this.

[0011] In the following description, the width direction is the direction in which the multiple writing instruments 12 are arranged. The longitudinal direction is perpendicular to the width direction and is the longitudinal direction of the writing instruments 12 held in the pen holder 10. The direction perpendicular to the width direction and longitudinal direction, and moving from the support surface 14 toward the writing instruments 12, is called the first direction, and the direction moving from the writing instruments 12 toward the support surface 14 is called the second direction. The terms width direction and longitudinal direction used in this description of this embodiment are used to describe the relative positions of the configuration of the pen holder 10 in this embodiment and do not necessarily coincide with the longitudinal direction and width direction of the pen cases 40, 100, 150, and 200 of the second to fifth embodiments.

[0012] The pen holder 10 comprises a support surface portion 14, a first holding portion 16, and a second holding portion 18. The support surface portion 14 is formed in a plate shape and has a support surface 15a and a lower surface 15b. The support surface portion 14 has sufficient strength to maintain its plate shape while supporting multiple writing instruments 12. The support surface portion 14 may be made of, for example, a thick cloth. Alternatively, the support surface portion 14 may be made of a resin sheet. In another example, the support surface portion 14 may be made by covering a relatively hard core material 14a with a surface material 14b, as shown in the figure. The dimensions of the support surface portion 14 in the width direction and longitudinal direction are not particularly limited, but at least they have dimensions that can cover all the writing instruments 12 held by the pen holder 10 from a second direction.

[0013] As shown in Figures 1 and 2A, the first holding portion 16 is formed on the support surface 15a and holds the first end of the writing instrument 12. In the illustrated example, the first holding portion 16 has a first cylindrical portion 20 through which the first end of the writing instrument 12 is inserted. Multiple first cylindrical portions 20 are provided in the width direction (six in the illustrated example). Each first cylindrical portion 20 has a first insertion hole 22 that extends in the longitudinal direction perpendicular to the width direction.

[0014] The first holding portion 16 is formed, for example, by a stretchable first strip-shaped sheet 17 that extends in the width direction. The first strip-shaped sheet 17 is formed, for example, by flat rubber. The flat rubber is made of knitted rubber, etc., in which stretchable rubber threads are knitted together with fiber threads, and is elastic. The first strip-shaped sheet 17 is sewn to the support surface portion 14 in a state where it is bent so as to bulge into a tube shape in the portion that forms the first tubular portion 20. The first strip-shaped sheet 17 is joined to the support surface portion 14 at first joining portions 24 provided on both sides of the first tubular portion 20. Note that the first strip-shaped sheet 17 is not limited to flat rubber, and may be made of a sheet body made of various fiber materials such as cloth, sponge, elastomer, rubber, paper, resin, etc.

[0015] The first joint portion 24 is the part to which the first strip-shaped sheet 17 is joined to the support surface portion 14 by methods such as stitching, welding, or bonding. In the illustrated example, it is joined to the surface material 14b by stitching. The first joint portion 24 extends in the longitudinal direction. The spacing between adjacent first joint portions 24 is equal to or slightly larger than the diameter of the writing instrument 12 to be held. There are one more first joint portions 24 than the number of first cylindrical portions 20. As shown in Figure 2A, the first holding portion 16 can be smoothly curved so as to be convex in the second direction by the elastic restoring force that causes the first strip-shaped sheet 17 to return to a flat shape at the first joint portion 24. The first insertion holes 22 of adjacent first cylindrical portions 20 are spaced apart in the width direction by the curved portion formed near the first joint portion 24.

[0016] The inner diameter of the first insertion hole 22 of the first cylindrical portion 20 is formed to be slightly smaller than the outer diameter of the writing instrument 12 to be held, and the writing instrument 12 can be inserted through it by elastic deformation. The first cylindrical portion 20 adheres tightly to the outer surface of the writing instrument 12 by the elastic restoring force of the first strip-shaped sheet 17 as it tries to return to its initial inner diameter, and holds the writing instrument 12 so that it cannot be displaced in the longitudinal direction, width direction and first direction. However, the first holding portion 16 alone cannot suppress the swinging of the area near the second end of the writing instrument 12 due to vibrations during transport, etc. Therefore, the pen holder 10 of this embodiment is equipped with a second holding portion 18 on the support surface 15a.

[0017] As shown in Figure 1, the second retaining portion 18 is positioned longitudinally apart from the first retaining portion 16. The second retaining portion 18 comprises a flexible second strip-shaped sheet 26 extending in the width direction. In this embodiment, the second strip-shaped sheet 26 is formed from flat rubber similar to that of the first strip-shaped sheet 17.

[0018] Furthermore, the second strip-shaped sheet 26 is not limited to flat rubber, but may be composed of a sheet made of various fibrous materials such as cloth, sponge, elastomer, rubber, paper, or resin that functions as a cushion between the writing instruments 12.

[0019] The second holding portion 18 has a plurality of second cylindrical portions 28 that clamp the writing instrument 12 from both sides. A holding space for holding the writing instrument 12 is formed between adjacent second cylindrical portions 28. The second cylindrical portions 28 are cylindrical parts formed by folding the second strip sheet 26 into a narrow shape and sewing its base portion 28a to the support surface portion 14 with a second joint portion 30. The second strip sheet 26 forms an overlapping portion 28c where the folded portions at the base portion 28a of the second cylindrical portion 28 are in close contact with each other. The second joint portion 30 extends in the longitudinal direction and sews the second strip sheet 26 to the support surface portion 14.

[0020] Furthermore, the second joint 30 between the support surface 14 and the base 28a is not limited to sutures, but may be formed by various joining structures such as adhesive or fusion, and the suture lines in this specification also include linear joining structures formed by adhesive or fusion.

[0021] As shown in Figure 2B, the second joint 30 has a first suture line 30a and a second suture line 30b. The first suture line 30a is located on one side in the width direction of the overlapping portion 28c, and the second suture line 30b is located on the other side in the width direction of the overlapping portion 28c.

[0022] The first suture line 30a and the second suture line 30b extend in the longitudinal direction. The widthwise position of the base 28a of the second tubular portion 28 is determined by the positions of the first suture line 30a and the second suture line 30b. The widthwise positions of the first suture line 30a and the second suture line 30b substantially coincide with the widthwise position 32 of the first joint 24 of the first holding portion 16 (the position of the side of the first tubular portion 20). Therefore, the widthwise position of the base 28a of the second tubular portion 28 is offset from the widthwise center position 34 of the first tubular portion 20.

[0023] The second cylindrical portion 28 is formed so that its projection height in the first direction is approximately the same as the height of the top of the first cylindrical portion 20 in the first direction. At the folded portion of the top 28b in the first direction, the second cylindrical portion 28 curves in the width direction due to the elastic restoring force of the second strip-shaped sheet 26 returning to a flat shape. The second cylindrical portion 28, having such a bulge, functions as a cushion to prevent contact between adjacent writing instruments 12. The inner diameter of the second cylindrical portion 28 is formed to be sufficiently smaller than the diameter of the writing instrument 12 to be held. Therefore, the second cylindrical portion 28 cannot be used to insert a writing instrument 12.

[0024] Between the second tubular portions 28, the second strip-shaped sheet 26 is sewn to the support surface portion 14 by a first suture line 30a and a second suture line 30b so as to be in close contact with the support surface portion 14. Therefore, a flat portion 36 of the second strip-shaped sheet 26 is formed between one adjacent second tubular portion 28 and the other second tubular portion 28. The flat portion 36 of the second strip-shaped sheet 26 supports the vicinity of the second end of the writing instrument 12.

[0025] The widthwise spacing of the adjacent second cylindrical portions 28 (width of the flat portion 36) may be approximately the same as the diameter of the writing instrument 12 to be held. Alternatively, the widthwise spacing of the second cylindrical portions 28 may be slightly larger than the diameter of the writing instrument 12. The second cylindrical portions 28 only cover the sides of the writing instrument 12. Therefore, the second holding portion 18 can expose the outer surface of the writing instrument 12, thus protecting the writing instrument 12 in a way that allows for easy viewing of its appearance. Thus, the pen holder 10 of this embodiment offers excellent visibility of the stored writing instrument 12.

[0026] (Second Embodiment) The pen case 40 of this embodiment, shown in Figure 3, includes the pen holder 10 described in the first embodiment. In describing the pen case 40 of this embodiment, components similar to those of the pen holder 10 described with reference to Figures 1 to 2B are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0027] As shown in Figure 3, the pen case 40 of this embodiment has a first storage compartment 44 that is opened and closed by a first fastener 42, and a second storage compartment 48 that is opened and closed by a second fastener 46. To form the first storage compartment 44 and the second storage compartment 48, the pen case 40 of this embodiment comprises a first main body 50, a second main body 52 (Figure 7) facing the first main body 50, and a third main body 54 (Figure 8) facing the second main body 52.

[0028] As shown in Figures 5 to 7, the first storage compartment 44 is formed by a first main body 50 and a second main body 52 connected via a first hinge portion 56. Also, as shown in Figure 8, the second storage compartment 48 is formed by a second main body 52 and a third main body 54. As shown in Figure 3, the second main body 52 is positioned between the first main body 50 and the third main body 54. As shown in Figure 4, the first main body 50 and the second main body 52 are connected by a first hinge portion 56 and a first fastener 42. The second main body 52 and the third main body 54 are connected by a connecting sheet 58 and a second fastener 46.

[0029] In the pen case 40 of this embodiment, the standard configuration is one in which the first main body 50 is positioned forward with the first fastener 42 closed and the first hinge 56 is positioned on the left side. In the standard configuration, the direction that vertically penetrates the first main body 50, the second main body 52, and the third main body 54 is called the front-to-back direction. In the front-to-back direction, the direction in which the first main body 50 is located is called the front side or forward, and the direction in which the third main body 54 is located is called the rear side or rear. Also, in the standard configuration, the left-to-right direction is called the width direction of the pen case 40. Within the width direction, the direction toward the left is called the left side or left direction, and the direction toward the right is called the right side or right direction. The direction perpendicular to the width direction and the front-to-back direction is called the longitudinal direction. Within the longitudinal direction, the direction toward upward is called the upper side or upward, and the direction toward downward is called the lower side or downward. These directional names only specify the relative positional relationship of the components of the pen case 40 and do not limit the orientation of the pen case 40 itself.

[0030] As shown in Figures 4 and 5, the first main body portion 50 has a front portion 60, a peripheral wall portion 62, a pen holder 10, a first fastener tape 64, and a first peripheral suture portion 66. The front portion 60 is the planar part located at the very front of the pen case 40. The front portion 60 is formed in a roughly rectangular, flat shape with rounded corners when viewed from above.

[0031] The front portion 60 comprises, for example, an elastic plate-shaped core material 14a and a pair of outer covering materials 14b that cover the front side (outside when closed) and rear side (inside when closed) of the core material 14a. The pair of outer covering materials 14b are made of, for example, fabric and are sewn together at a first peripheral seam 66 provided along the periphery of the front portion 60. The first peripheral seam 66 is a portion formed by folding the seam allowances of the pair of outer covering materials 14b toward the first housing chamber 44 (inside) and sewing them together, and has piping made by wrapping and sewing bias tape so as to hide the cut edges of the pair of outer covering materials 14b.

[0032] A first hinge portion 56 is connected to the left side (also called the first side) of the front portion 60, near the center. The first hinge portion 56 is made of a single piece of fabric or multiple pieces of fabric layered together. The first hinge portion 56 pivotably connects the first main body portion 50 to the second main body portion 52. The longitudinal dimension of the first hinge portion 56 is smaller than the longitudinal dimension of the front portion 60. The first hinge portion 56 is sewn to the front portion 60 together with a pair of skin materials 14b at the first peripheral seam portion 66.

[0033] The peripheral wall portion 62 protrudes briefly from the peripheral edge of the front portion 60, excluding the first hinge portion 56, toward the rear of the front portion 60. The peripheral wall portion 62 is provided in a C-shaped area in plan view. The peripheral wall portion 62 is made of the same fabric as the surface material 14b of the front portion 60. The peripheral wall portion 62 is sewn together with the pair of surface materials 14b at the first peripheral seam portion 66.

[0034] Furthermore, a first fastener tape 64 is sewn to the rear end of the peripheral wall portion 62. The first fastener tape 64 extends in a C-shape when viewed from above. The starting end of the first fastener tape 64 is sewn to the lower end of the first hinge portion 56, and the ending end of the first fastener tape 64 is sewn to the upper end of the first hinge portion 56. The first fastener tape 64, together with the second fastener tape 68 of the second main body portion 52, constitutes a part of the first fastener 42.

[0035] The first main body portion 50 is further provided with a pen holder 10 on the first storage chamber 44 side (inner surface) of the front portion 60. The pen holder 10 has the same structure as the pen holder 10 described with reference to Figures 1 to 2B. That is, the pen holder 10 comprises a first retaining portion 16 and a second retaining portion 18 sewn onto the surface material 14b on the rear side of the front portion 60. In this embodiment, the front portion 60 constitutes the support surface portion 14 of the pen holder 10. Note that the position of the pen holder 10 is not limited to the front portion 60 (inner surface of the first main body portion 50), but may also be the partition surface portion 70 (inner surface of the second main body portion 52) or the rear surface portion 92 (inner surface of the third main body portion 54), etc. These portions can also constitute the support surface portion 14.

[0036] As shown in Figure 7, the second main body 52 includes a partition surface 70, a first swing partition plate 72, a second swing partition plate 74, a first pocket 76, a second fastener tape 68, a third fastener tape 78, and a second peripheral seam 80 (Figure 8). The partition surface 70 is formed as a roughly rectangular flat plate with rounded corners in plan view and has the same dimensions as the front part 60. The partition surface 70 comprises an elastic plate-shaped core material 14a (see Figure 1) and a pair of surface materials 14b that cover both sides of the core material 14a. The surface material 14b of the partition surface 70 may be made of the same fabric material as the surface material 14b of the front part 60. The partition surface 70 separates the first storage compartment 44 and the second storage compartment 48.

[0037] As shown in Figure 8, a second peripheral suture portion 80 is formed on the periphery of the partition surface portion 70, where a pair of outer material 14b are sewn together. The second peripheral suture portion 80 is formed by folding the pair of outer material 14b toward the second storage chamber 48 and sewing them together. The second peripheral suture portion 80 is provided with piping, similar to the first peripheral suture portion 66, where the cut ends of the outer material 14b are wrapped with bias tape and sewn together.

[0038] Furthermore, the second peripheral suture portion 80 has the first hinge portion 56 (Figure 5), the second fastener tape 68, the third fastener tape 78, the second hinge portion 86 (Figure 7), and the third hinge portion 88 (Figure 7) sewn into it.

[0039] As shown in Figure 4, the first hinge portion 56 is sewn to the center of the left long side of the second main body portion 52. The first hinge portion 56 is sewn into the second peripheral seam portion 80 (Figure 8) so as to protrude forward from the partition surface portion 70. The second fastener tape 68 is sewn so as to protrude forward from the peripheral edge of the partition surface portion 70. The start and end ends of the second fastener tape 68 are sewn to the first hinge portion 56.

[0040] As shown in Figure 7, the second fastener tape 68 rises forward from the second main body 52 in a side wall shape together with the first hinge portion 56. The second fastener tape 68 of the second main body 52 is sutured to the second peripheral suture portion 80 together with the surface material 14b. The first fastener tape 64 and the second fastener tape 68 are provided with a first slider 82. By moving the first slider 82 from the start end to the end, the first fastener tape 64 of the first main body 50 and the second fastener tape 68 of the second main body 52 interlock, and the first storage chamber 44 is closed.

[0041] A first pocket 76 is provided on the front side of the partition surface 70. The first pocket 76 is a storage area formed between the partition surface 70 and a first pocket sheet 84, which is positioned to cover the entire area of ​​the partition surface 70, and can accommodate thin items. The left and right sides and bottom edge of the first pocket sheet 84 are sewn together by a second peripheral seam 80. The top of the first pocket sheet 84 is not sewn together and forms the opening 76a of the first pocket 76.

[0042] As shown in Figures 5 to 7, the first oscillating partition plate 72 is a roughly rectangular plate-like member with dimensions smaller than the partition surface portion 70. The first oscillating partition plate 72 is constructed by covering both sides of a plate-shaped core material 14a with a surface material 14b. Piping is provided on the periphery of the first oscillating partition plate 72 to conceal the cut edges of the surface material 14b. The second hinge portion 86 is sewn into the piping of the first oscillating partition plate 72.

[0043] The first oscillating partition plate 72 has dimensions (area) that can cover the pen holder 10 and the writing instrument 12. The first oscillating partition plate 72 is positioned between the pen holder 10 provided on the front portion 60 and the pen holder 10 provided on the second oscillating partition plate 74, and functions as a cushion to prevent contact between the writing instruments 12 held by them.

[0044] The first pivoting partition plate 72 is sewn to the left long side of the partition surface 70 via a second hinge portion 86. The second hinge portion 86 is made of a strip of fabric with the same length in the longitudinal direction as the first hinge portion 56. Therefore, the longitudinal dimension of the second hinge portion 86 is smaller than the longitudinal dimension of the first pivoting partition plate 72. The second hinge portion 86 is located on the left long side of the partition surface 70 and is superimposed with the first hinge portion 56 and sewn into the second peripheral seam portion 80. Such a second hinge portion 86 facilitates the pivoting of the first pivoting partition plate 72.

[0045] As shown in Figures 6 and 7, the second oscillating partition plate 74 is a plate-shaped member having the same dimensions as the first oscillating partition plate 72. The second oscillating partition plate 74 is constructed by covering both sides of a plate-shaped core material 14a with a surface material 14b. The periphery of the first oscillating partition plate 72 is provided with piping to conceal the cut edges of the surface material 14b. Multiple mesh pockets 90 are formed on the rear surface of the second oscillating partition plate 74 by overlapping and sewing together mesh fabric. A pen holder 10 is provided on the front surface 74a of the second oscillating partition plate 74.

[0046] The pen holder 10 has a structure similar to that of the pen holder 10 described with reference to Figures 1 to 2B. The first holding portion 16 and the second holding portion 18 are sewn to the front surface material 14b of the second oscillating partition plate 74. The second oscillating partition plate 74 constitutes the support surface portion 14 of the pen holder 10.

[0047] The second pivoting partition plate 74 is connected to the partition surface portion 70 via a third hinge portion 88. In this embodiment, the third hinge portion 88 is sewn to the right long side opposite to the second hinge portion 86. Therefore, the second pivoting partition plate 74 can be unfolded in the opposite direction to the first pivoting partition plate 72.

[0048] The third hinge portion 88 is made of a strip of fabric having the same length in the longitudinal direction as the first hinge portion 56. Therefore, the longitudinal dimension of the third hinge portion 88 is smaller than the longitudinal dimension of the first swinging partition plate 72. The third hinge portion 88 is sewn into the second peripheral seam portion 80 on the longer right side of the partition surface portion 70. Such a third hinge portion 88 facilitates the swinging of the second swinging partition plate 74.

[0049] As shown in Figure 8, the third fastener tape 78 and the connecting sheet 58 are sewn to the partition surface 70 so as to protrude rearward from the peripheral edge. The connecting sheet 58 is provided in an area extending from the left side of the partition surface 70 to a part of the top edge and a part of the bottom edge. The third fastener tape 78 is positioned in the area where the connecting sheet 58 is not provided. The starting end of the third fastener tape 78 is sewn to the bottom edge of the connecting sheet 58, and the ending end of the third fastener tape 78 is sewn to the top edge of the connecting sheet 58. The third fastener tape 78, together with the fourth fastener tape 94 described later, constitutes a part of the second fastener 46. The second main body 52 of this embodiment is configured as described above.

[0050] The third main body 54 is connected to the second main body 52 via a connecting sheet 58 and a second fastener 46. The third main body 54 has a rear section 92 and a fourth fastener tape 94. The rear section 92 has the same planar shape and dimensions as the front section 60 and the partition section 70. The rear section 92 comprises a plate-shaped core material 14a and a pair of surface materials 14b that cover both sides of the core material 14a. The surface materials 14b are the same as the surface materials 14b of the front section 60. A third peripheral seam 96 is formed at the periphery of the rear section 92 so as to protrude toward the second storage compartment 48. The fourth fastener tape 94 and the connecting sheet 58 are also sewn into the third peripheral seam 96.

[0051] The third fastener tape 78 and the fourth fastener tape 94 have a portion of the second slider 98. When the second slider 98 is slid from the start end to the end, the third fastener tape 78 and the fourth fastener tape 94 interlock, causing the second fastener 46 to close, and the second containment chamber 48 is closed by the second fastener 46.

[0052] The pen case 40 of this embodiment is configured as described above. The pen case 40 of this embodiment includes a pen holder 10. Therefore, the pen case 40 offers excellent accessibility for the writing instrument 12 and can satisfy the needs of users who have an attachment to their writing instrument 12.

[0053] Furthermore, the first oscillating partition plate 72 prevents contact between the writing instrument 12 held in the pen holder 10 of the first main body 50 and the writing instrument 12 held in the pen holder 10 of the second oscillating partition plate 74, thereby preventing damage to the writing instrument 12 due to vibrations during transport. In addition, if it is necessary to conceal a high-quality writing instrument 12 depending on the situation, the first oscillating partition plate 72 can be used to cover the pen holder 10 of either the first main body 50 or the second oscillating partition plate 74, thereby alleviating the user's anxiety.

[0054] (Third embodiment) The pen case 100 of this embodiment, shown in Figure 9, includes the pen holder 10 described in the first embodiment. In describing the pen case 100 of this embodiment, components similar to those of the pen holder 10 described with reference to Figures 1 to 2B are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0055] As shown in Figures 9 and 10, the pen case 100 of this embodiment includes a first storage compartment 104 that is opened and closed by a first fastener 102. The pen case 100 comprises a first main body 106 and a second main body 108 to form the first storage compartment 104. The first main body 106 and the second main body 108 are pivotably connected via a first hinge 110.

[0056] In the pen case 100 of this embodiment, the standard configuration is one in which the first main body 106 is positioned forward with the first fastener 102 closed and the first hinge 110 is positioned on the left side. In the standard configuration, the direction that vertically penetrates the first main body 106 and the second main body 108 is called the front-to-back direction, the direction in which the first main body 106 is located in the front-to-back direction is called the front side or forward, and the direction in which the second main body 108 is located is called the rear side or rear. Also, in the standard configuration, the horizontal direction is called the width direction of the pen case 100, the direction toward the left in the width direction is called the left side or left direction, and the direction toward the right is called the right side or right direction. The direction perpendicular to the width direction and the front-to-back direction is called the longitudinal direction. In the longitudinal direction, the direction toward upward is called the upper side or upward, and the direction toward downward is called the lower side or downward. These directional names only specify the relative positional relationship of the components of the pen case 100 and do not limit the configuration of the pen case 100 itself.

[0057] As shown in Figures 9 and 11, the first main body portion 106 has a front portion 112, a first peripheral suture portion 114, and a first fastener tape 116. The front portion 112 is formed in a substantially rectangular shape with a longitudinal dimension greater than the width dimension in a plan view, and with rounded corners. The front portion 112 is formed of a transparent resin sheet such as PVC resin, allowing the inside of the first storage chamber 104 to be seen.

[0058] The first peripheral seam 114 is formed along the periphery of the front portion 112. The first fastener tape 116 and the first hinge portion 110 are sewn to the resin sheet constituting the front portion 112 in the first peripheral seam 114. The first peripheral seam 114 is formed to protrude from the front portion 112 toward the first housing chamber 104. The first peripheral seam 114 has piping that is wrapped and sewn with bias tape to conceal the cut edges of the members to be sewn.

[0059] One end of the first hinge portion 110 in the front-rear direction is joined to the first main body portion 106 via the first peripheral seam portion 114 near the center of the left side of the first main body portion 106. The first hinge portion 110 is made of fabric and pivotably connects the first main body portion 106 to the second main body portion 108.

[0060] The first fastener tape 116 is arranged in a C-shape along the periphery of the first main body portion 106 in the portion where the first hinge portion 110 is not provided. The starting end of the first fastener tape 116 is sewn to the lower end of the first hinge portion 110, and the ending end of the first fastener tape 116 is sewn to the upper end of the first hinge portion 110. The first fastener tape 116 sewn to the first main body portion 106, together with the second fastener tape 118, constitutes the first fastener 102.

[0061] As shown in Figure 10, the second main body 108 has a larger front-to-back dimension than the first main body 106 and forms most of the first storage chamber 104. The second main body 108 comprises a rear surface 120, a side wall 122, a second peripheral suture 124, a third peripheral suture 126, a first swing partition plate 130, and a second fastener tape 118. The rear surface 120 has the same shape and dimensions as the front surface 112 in plan view and is formed from a transparent resin sheet similar to that of the front surface 112.

[0062] The second peripheral suture portion 124 is formed along the periphery of the rear portion 120. The second peripheral suture portion 124 is the portion that joins the periphery of the rear portion 120 and the side wall portion 122 by suturing. The second peripheral suture portion 124 is formed by folding the periphery of the rear portion 120 forward, inward from the rear portion 120. The second peripheral suture portion 124 has piping that is wrapped and sutured with bias tape to hide the cut edge.

[0063] The side wall portion 122 is formed to rise forward from the periphery of the rear portion 120. The side wall portion 122 has an opaque portion 122a and a transparent portion 122b. The opaque portion 122a is made of the same fabric as the first hinge portion 110 and is integrally connected to the first hinge portion 110. The end of the opaque portion 122a is joined to the left long side of the rear portion 120 via the second peripheral seam portion 124. The longitudinal dimension of the opaque portion 122a is smaller than the longitudinal dimension of the rear portion 120. Therefore, the transparent portion 122b is joined to a part of the upper part of the left long side of the rear portion 120 and a part of the lower part of the rear portion 120 via the second peripheral seam portion 124.

[0064] The transparent portion 122b is formed from a transparent resin sheet similar to the rear portion 120. The transparent portion 122b is located in the part of the periphery of the rear portion 120 where the opaque portion 122a is not formed, and is positioned in a C-shaped portion in plan view. The rear end of the transparent portion 122b is joined to the rear portion 120 via the second peripheral suture portion 124. The lower end of the transparent portion 122b is sutured to the lower end of the opaque portion 122a, and the upper end of the transparent portion 122b is sutured to the upper end of the opaque portion 122a. In this way, the side wall portion 122 formed by the opaque portion 122a and the transparent portion 122b is formed in a substantially rectangular cylindrical shape.

[0065] A third peripheral suture portion 126 is provided at the front end (front end) of the transparent portion 122b of the side wall portion 122. A second fastener tape 118 is sewn to the third peripheral suture portion 126. The second fastener tape 118 is formed in a C-shape in plan view along the front end of the transparent portion 122b. The starting end of the second fastener tape 118 is sewn to the lower end of the opaque portion 122a, and the ending end of the second fastener tape 118 is sewn to the upper end of the opaque portion 122a. The first fastener tape 116 and the second fastener tape 118 form the first fastener 102. The first fastener 102 has a slider 132. When the slider 132 is moved from the starting end to the ending end, the first fastener 102 closes, and the first containment chamber 104 is closed.

[0066] As shown in Figure 11, the first containment chamber 104 houses the first swinging partition plate 130.

[0067] As shown in Figure 12, the first oscillating partition plate 130 has a width dimension greater than the width dimension of the front portion 112 or the rear portion 120, and a length dimension smaller than the length dimension of the front portion 112 or the rear portion 120, and is formed as a flat plate that is approximately square in plan view. The first oscillating partition plate 130 has two surface materials 14b made of fabric, and has a first portion 134 that contains one core material 14a and a second portion 136 that contains the other core material 14a. A pen holder 10 is formed on the front surface of the first portion 134. The pen holder 10 has the same configuration as the pen holder 10 described with reference to Figures 1 to 2B. In this embodiment, the pen holder 10 can accommodate five writing instruments 12.

[0068] The core material 14a of the second part 136 is positioned apart in the width direction from the core material 14a of the first part 134. Therefore, a bendable flex portion 138 without a core material 14a is formed between the first part 134 and the second part 136. The second part 136 can be folded back so as to overlap the front or rear of the first part 134. With the second part 136 folded back so as to overlap the first part 134, the first swing partition plate 130 is housed in the first storage chamber 104.

[0069] As shown in Figure 13, the rear surface of the first swing partition plate 130 is provided with a plurality of bar tapes 140 and a plurality of mesh pockets 142. A pair of bar tapes 140 are arranged on the rear surface of the first section 134. The bar tapes 140 are made of flat rubber and are positioned to abut against the surface material 14b on the rear side of the first section 134, with both ends sewn together with piping around the edge. The pair of bar tapes 140 are spaced a predetermined distance apart in the longitudinal direction. The bar tapes 140 are suitable for holding thin and relatively long objects such as rulers. The mesh pockets 142 are located on the rear side of the second section 136. The mesh pockets 142 are formed by sewing a stretchable mesh fabric to the rear surface of the second section 136.

[0070] For example, as shown in Figure 11, by folding the second part 136 back to the rear side of the first part 134, the pen holder 10 becomes visible through the front part 112 and the side wall part 122. Also, depending on the situation, as shown in Figure 14, the writing instrument 12 stored in the pen holder 10 can be hidden by folding the second part 136 back to the front side of the first part 134.

[0071] The first oscillating partition plate 130 is joined to the second peripheral seam portion 124 via a second hinge portion 144. The second hinge portion 144 is formed from a strip of fabric. The longitudinal dimension of the second hinge portion 144 is smaller than the longitudinal dimension of the first oscillating partition plate 130. Also, the widthwise dimension of the second hinge portion 144 is approximately equal to the front-to-back dimension of the side wall portion 122. Therefore, as shown in Figure 15, the first oscillating partition plate 130 can be separated from the rear portion 120, and a storage space capable of accommodating thick small items can be formed between the rear portion 120 and the first oscillating partition plate 130.

[0072] The pen case 100 of this embodiment is equipped with a pen holder 10 that provides excellent visibility of the writing instrument 12. Furthermore, since most of the front 112, rear 120, and side walls 122 are transparent, the writing instrument 12 stored in the pen holder 10 can be stored in a way that allows it to be seen from the outside, thereby increasing the satisfaction of users who have an emotional attachment to their writing instrument 12.

[0073] Furthermore, the pen case 100 of this embodiment can also conceal the writing instrument 12 held in the pen holder 10 by folding the second portion 136 of the first pivoting partition plate 130 in front of the first portion 134. If the user wishes to conceal an expensive writing instrument 12, folding the second portion 136 to the front of the first portion 134 can enhance the user's sense of security.

[0074] (Fourth Embodiment) The pen case 150 of this embodiment, shown in Figure 16, is made of a relatively hard and deformation-resistant material. The pen case 150 of this embodiment also includes the pen holder 10 described in the first embodiment. In describing the pen case 150 of this embodiment, components similar to those of the pen holder 10 described with reference to Figures 1 to 2B are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0075] As shown in Figures 16 and 17, the pen case 150 of this embodiment includes a first storage compartment 154 that is opened and closed by a first fastener 152. The pen case 150 comprises a first main body 156 and a second main body 158 to form the first storage compartment 154. The first main body 156 and the second main body 158 are pivotably connected via a first hinge 160.

[0076] In the pen case 150 of this embodiment, the standard configuration is one in which the first main body 156 is positioned forward with the first fastener 152 closed and the first hinge 160 is positioned on the left side. In the standard configuration, the direction that vertically penetrates the first main body 156 and the second main body 158 is called the front-to-back direction, the direction in which the first main body 156 is located in the front-to-back direction is called the front side or forward, and the direction in which the second main body 158 is located is called the rear side or rear. Also, in the standard configuration, the horizontal direction is called the width direction of the pen case 150, the direction toward the left in the width direction is called the left side or left direction, and the direction toward the right is called the right side or right direction. The direction perpendicular to the width direction and the front-to-back direction is called the longitudinal direction. In the longitudinal direction, the direction toward upward is called the upper side or upward, and the direction toward downward is called the lower side or downward. These directional names only specify the relative positional relationship of the components of the pen case 150 and do not limit the configuration of the pen case 150 itself.

[0077] As shown in Figures 16 to 18, the first main body portion 156 comprises a front portion 162, a first side wall portion 164, a first peripheral seam portion 166, and a first fastener tape 168. Within the first main body portion 156, the front portion 162 and the first side wall portion 164 are integrally connected and formed. The front portion 162 and the first side wall portion 164 are formed by covering the surface of a concave core material 14a, which is made of, for example, a rigid EVA resin, with a surface material 14b. Although not particularly limited, the surface material 14b covering the outer surface (top surface) of the front portion 162 and the first side wall portion 164 may be made of, for example, a urethane elastomer material and have a textured surface and gloss like leather. The surface material 14b covering the inner surface (rear surface) (Figure 18) may be felt fabric.

[0078] The front portion 162 is provided with a plurality of groove-shaped or rectangular first recesses 170 to prevent small items such as writing instruments 12 from falling off when these items are placed on it. The first side wall portion 164 rises in a wall-like manner from the periphery of the front portion 162 toward the rear. As shown in Figure 21, a first peripheral suture portion 166 is provided at the rear end of the first side wall portion 164.

[0079] As shown in Figure 18, the first peripheral seam 166 is formed along the end of the first side wall 164 and extends around the entire circumference of the periphery of the first main body 156. The first hinge 160 and the first fastener tape 168 are sewn to the first peripheral seam 166. The first peripheral seam 166 has piping to conceal the cut edge of the fabric to be connected.

[0080] As shown in Figure 17, the first hinge portion 160 is located in the center of the left side of the first main body portion 156. The first hinge portion 160 is made of a strip-shaped sheet material and connects the left side of the first main body portion 156 to the left side of the second main body portion 158. As shown in Figure 18, the first hinge portion 160 connects the first main body portion 156 to the second main body portion 158 so that it can swing by 180° or more.

[0081] The first fastener tape 168 constitutes a part of the first fastener 152. The first fastener tape 168 extends along the periphery of the first side wall portion 164, excluding the first hinge portion 160. In plan view, the first fastener tape 168 extends in a C-shaped area. The starting end of the first fastener tape 168 is sewn to the lower end of the first hinge portion 160, and the ending end of the first fastener tape 168 is sewn to the upper end of the first hinge portion 160.

[0082] As shown in Figure 17, the second main body portion 158 includes a rear portion 172, a second side wall portion 174, a second peripheral suture portion 176, a second fastener tape 178, a first oscillating partition plate 180, and a second oscillating partition plate 182. The rear portion 172 is formed in a substantially rectangular shape that extends long in the longitudinal direction when viewed from above. Multiple groove-shaped second recesses 184 that extend long in the longitudinal direction are formed on the surface of the rear portion 172.

[0083] The second side wall portion 174 is integrally formed from the same material as the rear portion 172. The second side wall portion 174 rises in a wall-like manner from the periphery of the rear portion 172 toward the front. The second side wall portion 174 is formed around the entire periphery of the rear portion 172. The projection height of the second side wall portion 174 in the front-rear direction is greater than the projection height of the first side wall portion 164 of the first main body portion 156 in the front-rear direction. Therefore, most of the first accommodation chamber 154 is formed by the second main body portion 158. The rear portion 172 and the second side wall portion 174 are formed from the same core material 14a and surface material 14b as the front portion 162 and the first side wall portion 164.

[0084] As shown in Figure 20, the upper short side (upper end) of the second side wall 174 is provided with a first projection 186 that protrudes inward into the first storage chamber 154. The lower short side (lower end) of the second side wall 174 is provided with a second projection 188 that protrudes inward into the first storage chamber 154. The first projection 186 and the second projection 188 prevent the first or second swinging partition plate 180 or 182, which will be described later, from approaching the rear surface 172. As a result, as shown in Figure 21, a storage space 190 capable of accommodating small items is formed between the first or second swinging partition plate 180 or 182 and the rear surface 172.

[0085] As shown in Figure 18, the second peripheral suture portion 176 extends circumferentially along the front end of the second side wall portion 174. The first hinge portion 160 and the second fastener tape 178 are sutured to the second peripheral suture portion 176. The first hinge portion 160 is sutured to the left side of the second main body portion 158. The second fastener tape 178 is sutured to the second peripheral suture portion 176 in the portion where the first hinge portion 160 is not provided.

[0086] Furthermore, as shown in Figure 20, the second peripheral suture portion 176 is sutured to a second hinge portion 192 for connecting the first pivoting partition plate 180 and a third hinge portion 194 for connecting the second pivoting partition plate 182.

[0087] The second hinge portion 192 is sutured to the second peripheral suture portion 176 on the left side of the second main body portion 158, overlapping with the first hinge portion 160. The third hinge portion 194 is sutured to the second peripheral suture portion 176 on the right side of the second main body portion 158.

[0088] As shown in Figures 18 and 19, the first swinging partition plate 180 can swing relative to the second main body 158 as if turning a page, via the second hinge portion 192. The first swinging partition plate 180 is a plate-shaped member formed by covering both sides of an elastic plate-shaped core material 14a with a surface material 14b. The surface material 14b of the first swinging partition plate 180 is made of, for example, fabric. The first swinging partition plate 180 is formed in a roughly rectangular shape that extends long in the longitudinal direction, and its dimensions are smaller than the internal dimensions of the first storage chamber 154. Piping is formed around the entire periphery of the first swinging partition plate 180 by wrapping the cut end of the surface material 14b with bias tape and sewing it together. The end of the second hinge portion 192 is sewn to the left side of the first swinging partition plate 180.

[0089] As shown in Figure 18, a pen holder 10 is provided on the front side of the first swinging partition plate 180. The pen holder 10 has the same structure as the pen holder 10 described with reference to Figures 1 to 2B. The first holding part 16 and the second holding part 18 of the pen holder 10 in this embodiment can accommodate, for example, four writing instruments 12.

[0090] As shown in Figure 19, a pair of bar tapes 196 are provided on the rear surface of the first oscillating partition plate 180. The bar tapes 196 are made of flat rubber and are positioned in contact with the rear surface of the first oscillating partition plate 180, with both ends sewn together by piping around the edge. The pair of bar tapes 196 are spaced apart by a predetermined distance in the longitudinal direction. The bar tapes 196 are suitable for holding and securing thin, relatively long objects such as rulers.

[0091] The second pivoting partition plate 182 is sewn to the right side of the second main body 158 via a third hinge portion 194. As shown in Figure 20, the second pivoting partition plate 182 can pivot relative to the second main body 158 as if turning a page. The second pivoting partition plate 182 unfolds in the opposite direction to the first pivoting partition plate 180. In the examples of Figures 18 and 19, the second pivoting partition plate 182 is positioned behind the first pivoting partition plate 180, but the arrangement is not limited to this, and the second pivoting partition plate 182 may be positioned in front of the first pivoting partition plate 180.

[0092] The second oscillating partition plate 182 has the same shape and dimensions as the first oscillating partition plate 180. The second oscillating partition plate 182 is formed by arranging a surface material 14b (fabric) on both sides of an elastic plate-shaped core material 14a, and has piping around its periphery.

[0093] The second oscillating partition plate 182 has a pen holder 10 on its front side. The pen holder 10 has the same structure as the pen holder 10 described with reference to Figures 1 to 2B. The first holding part 16 and the second holding part 18 of the pen holder 10 in this embodiment can hold, for example, four writing instruments 12. The second oscillating partition plate 182 also has a knob 198 on the left side of its front surface, which is a short, ring-shaped projection of a strip of tape (fabric). The knob 198 facilitates gripping the second oscillating partition plate 182 and allows for smooth deployment of the second oscillating partition plate 182.

[0094] As shown in Figure 20, when the second swing partition plate 182 is unfolded 180° from its retracted position, the rear surface of the second swing partition plate 182 is revealed. A mesh pocket 199 is formed on the rear surface of the second swing partition plate 182 by attaching the periphery of a mesh-like fabric (mesh material) to the second swing partition plate 182. The top of the mesh pocket 199 is an opening 199a. In the illustrated example, two mesh pockets 199 are provided.

[0095] As shown in Figure 21, the pen case 150 of this embodiment accommodates multiple writing instruments 12 in the first storage compartment 154 by arranging the first oscillating partition plate 180 and the second oscillating partition plate 182 in storage positions. In the storage positions, the pen holders 10 of the first oscillating partition plate 180 and the pen holders 10 of the second oscillating partition plate 182 are superimposed on each other without facing each other. Therefore, the writing instruments 12 stored in the pen holders 10 of the first oscillating partition plate 180 and the writing instruments 12 stored in the pen holders 10 of the second oscillating partition plate 182 are prevented from coming into contact with each other, thus preventing contact between the writing instruments 12 due to vibrations during transport.

[0096] Furthermore, the pen case 150, through the first and second protrusions 186 and 188 of the second main body portion 158, can form a storage space 190 for storing small items between the second swinging partition plate 182 and the rear portion 172. For this reason, the pen case 150 of this embodiment is suitable for small items other than writing instruments 12. The pen case 150 is also suitable for storing items such as smartphones that you want to avoid frequent contact with the second swinging partition plate 182.

[0097] (Fifth embodiment) The pen case 200 of this embodiment, shown in Figure 22, is formed to be relatively thin. As shown in Figure 26, the pen case 200 of this embodiment supports the first main body 206 and the second main body 208 with the first swinging partition plate 202 and the second swinging partition plate 204, allowing the first main body 206 and the second main body 208 to be used upright on a desk. The pen case 200 is equipped with the pen holder 10 described in the first embodiment on the second swinging partition plate 204. In the description of the pen case 200 of this embodiment, components similar to those of the pen holder 10 described with reference to Figures 1 to 2B are denoted by the same reference numerals, and their detailed description is omitted.

[0098] As shown in Figures 22 and 23, the pen case 200 of this embodiment has a first storage compartment 212 that is opened and closed by a first fastener 210. The pen case 200 comprises a first body portion 206 and a second body portion 208 to form the first storage compartment 212. The first body portion 206 and the second body portion 208 are pivotably connected via a first hinge portion 214.

[0099] In this embodiment, the outer surface material 14b of the first main body 206, the outer surface material 14b of the first hinge 214, and the outer surface material 14b of the second main body 208 are integrally connected by a single sheet. Furthermore, the inner surface material 14b of the first main body 206, the inner sheet of the first hinge 214, and the inner surface material 14b of the second main body 208 are integrally connected by a single sheet. The first hinge 214 does not have a core material 14a built in, and can be bent flexibly.

[0100] In the pen case 200 of this embodiment, as shown in Figure 22, the standard configuration is one in which the first main body 206 is positioned forward with the first fastener 210 closed and the first hinge 214 is positioned on the left side. In the standard configuration, the direction that vertically penetrates the first main body 206 and the second main body 208 is called the front-to-back direction, the direction in which the first main body 206 is located in the front-to-back direction is called the front side or forward, and the direction in which the second main body 208 is located is called the rear side or rear. Also, in the standard configuration, the horizontal direction is called the width direction of the pen case 200, the direction toward the left in the width direction is called the left side or left direction, and the direction toward the right is called the right side or right direction. The direction perpendicular to the width direction and the front-to-back direction is called the longitudinal direction. In the longitudinal direction, the direction toward upward is called the upper side or upward, and the direction toward downward is called the lower side or downward. These directional names merely specify the relative positional relationships of the components of the pen case 200 and do not limit the arrangement of the pen case 200 itself.

[0101] As shown in Figures 22 to 26, the first main body portion 206 comprises a front portion 216, a first fastener tape 218, a first oscillating partition plate 202, a second hinge portion 228, and a first stopper 230. The front portion 216 has a substantially rectangular shape that extends long in the direction of its longer side when viewed from the front. The front portion 216 is constructed by covering the outer surface (top surface) of an elastic plate-shaped core material 14a with an outer surface material 14c, and covering the inner surface (bottom surface 15b) of the core material 14a with an inner surface material 14d. The outer surface material 14c is formed from, for example, a sheet material having the texture of leather made of urethane material. The inner surface material 14d can be formed from, for example, a fabric using a resin material such as nylon or polyester. The core material 14a, the outer surface material 14c, and the inner surface material 14d are sutured to each other by a surface material suture line 220 that extends along the periphery of the front portion 216.

[0102] The first hinge portion 214 is integrally connected to the left side of the first main body portion 206. The longitudinal dimension of the first hinge portion 214 is smaller than the longitudinal dimension of the first main body portion 206. Notches 222 are formed at the top and bottom of the first hinge portion 214, where the outer surface material 14c and the inner surface material 14d are cut out in a concave shape. The first hinge portion 214 is integrally connected to the left side of the second main body portion 208. The first hinge portion 214 does not contain a core material 14a and connects the first main body portion 206 and the second main body portion 208 so that they can swing relative to each other.

[0103] The first fastener tape 218 constitutes part of the first fastener 210 and extends along the periphery of the first main body portion 206. The starting end of the first fastener tape 218 is sewn to the lower end of the first hinge portion 214, and the ending end of the first fastener tape 218 is sewn to the upper end of the first hinge portion 214. The side end of the first fastener tape 218 is sandwiched between the outer skin material 14c and the inner skin material 14d and sewn into the skin material stitching line 220.

[0104] As shown in Figure 24, the first swing partition plate 202 is positioned on the first storage compartment 212 side of the first main body 206. The first swing partition plate 202 is a roughly rectangular plate-shaped member smaller than the front part 216. The first swing partition plate 202 is formed by covering both the front and rear surfaces of a relatively rigid plate-shaped core material 14a with a surface material 14b (fabric). A first pocket sheet 224 and a second pocket sheet 226 are superimposed on the first surface 202a of the first swing partition plate 202. The first pocket sheet 224 is positioned to cover the first surface 202a, except for a part of the upper part. The second pocket sheet 226 is a mesh fabric positioned to cover the first pocket sheet 224. The first pocket sheet 224 and the second pocket sheet 226 form two pocket compartments that overlap in the front-to-back direction. These pockets have openings 224a and 226a at the top.

[0105] As shown in Figures 26 and 27A, a second hinge portion 228 is connected to the upper edge of the first pivoting partition plate 202. The second hinge portion 228 is connected to the upper edge of the first main body portion 206 from the inner side of the first main body portion 206. In other words, the first pivoting partition plate 202 is pivotably connected to the upper edge of the first main body portion 206 via the second hinge portion 228. A strip-shaped first stopper 230 is connected to the bottom edge of the first pivoting partition plate 202. The first stopper 230 is connected to the bottom edge of the first main body portion 206 from the inner side of the first main body portion 206. The length of the first stopper 230 is longer than that of the second hinge portion 228. The first stopper 230 prevents the base of the first swinging partition plate 202 from spreading too wide when the base of the first swinging partition plate 202 swings away from the first main body 206, thereby stabilizing the first swinging partition plate 202 in an oblique position relative to the first main body 206.

[0106] As shown in Figures 23, 24, 25, and 26, the second main body 208 comprises a rear surface 244, a second fastener tape 242, a second oscillating partition plate 204, a third hinge portion 232, and a second stopper 234. The rear surface 244 has a substantially rectangular shape that extends long in the longitudinal direction when viewed from the rear. The rear surface 244 is constructed by covering the outer surface (rear surface) of an elastic plate-shaped core material 14a with an outer surface material 14c, and covering the inner surface (front surface) of the core material 14a with an inner surface material 14d. The outer surface material 14c is integrally connected to the outer surface material 14c of the first main body 206. The inner surface material 14d is integrally connected to the inner surface material 14d of the second main body 208. A suture line 220 for sutures the outer surface material 14c and the inner surface material 14d is formed on the peripheral edge of the rear surface portion 244 of the second main body portion 208. The suture line 220 extends in a circular manner along the peripheral edges of the first main body portion 206, the first hinge portion 214, and the second main body portion 208.

[0107] The left side (first side) of the second main body 208 is integrally connected to the first hinge 214. The second fastener tape 242 constitutes part of the first fastener 210 and extends along the periphery of the second main body 208. The starting end of the second fastener tape 242 is sewn to the lower end of the first hinge 214, and the ending end of the second fastener tape 242 is sewn to the upper end of the first hinge 214. The side end of the second fastener tape 242 is sandwiched between the outer skin material 14c and the inner skin material 14d and sewn into the skin material stitching line 220.

[0108] As shown in Figures 24 and 25, the second oscillating partition plate 204 is positioned on the inner surface (front surface) of the second main body portion 208. The first oscillating partition plate 202 comprises a first portion 236 consisting of a roughly rectangular plate-like member that is slightly smaller than the front portion 216, and a second portion 238 extending from the side of the first portion 236. The first portion 236 of the first oscillating partition plate 202 is formed by covering both the upper and lower surfaces of a relatively rigid plate-like core material 14a with a surface material 14b (fabric). The second portion 238 extends integrally with the first portion 236 via a bent portion 240 on the right side (second side edge). The second portion 238 does not contain the core material 14a and can be flexibly bent. The second portion 238 has the same dimensions as the first portion 236. As shown in Figure 25, by overlapping the second part 238 on the front of the first part 236, the second part 238 can cover the entire area of ​​the first part 236.

[0109] Furthermore, as shown in Figure 25, the second portion 238 can also be folded back and stored behind the first portion 236. A pen holder 10 is provided on top of the first portion 236 of the second swinging partition plate 204. The pen holder 10 has the same structure as the pen holder 10 described with reference to Figures 1 to 2B. The first holding portion 16 and the second holding portion 18 of this embodiment are configured to accommodate, for example, six writing instruments 12.

[0110] As shown in Figure 27B, a third hinge portion 232 is connected to the upper edge of the first portion 236 of the second pivoting partition plate 204. The third hinge portion 232 is connected to the upper edge of the rear portion 244 on the inner surface (front side) of the rear portion 244. In other words, the second pivoting partition plate 204 is pivotably connected around the upper edge of the rear portion 244 via the third hinge portion 232. A strip-shaped second stopper 234 is connected to the bottom edge of the first portion 236 of the second pivoting partition plate 204. The second stopper 234 is connected to the bottom edge of the second main body portion 208 on the inner surface (front side) of the rear portion 244. The length of the second stopper 234 in the front-rear direction is longer than that of the third hinge portion 232. The second stopper 234 prevents the base of the second swinging partition plate 204 from spreading too wide when the base of the first portion 236 of the second swinging partition plate 204 swings away from the second main body 208. As a result, the second stopper 234 stabilizes the second swinging partition plate 204 in an oblique position relative to the second main body 208.

[0111] The pen case 200 of this embodiment is configured as described above. By extending the first swinging partition plate 202 and the second swinging partition plate 204 diagonally relative to the first main body 206 and the second main body 208, the pen case 200 can stand upright on a desk with its base facing upwards. As a result, the pen case 200 of this embodiment can be used as a pen stand.

[0112] (Sixth Embodiment) As shown in Figure 28, the pen holder 280 of this embodiment is configured to be detachable from the pen case 320 of this embodiment shown in Figure 32. In the pen holder 280, components common to the pen holder 10 of the first embodiment are denoted by the same reference numerals, and their detailed descriptions are omitted. The pen holder 280 comprises a support surface portion 14, a covering surface portion 281 configured to cover the support surface portion 14, and a connecting portion 283 that connects the support surface portion 14 and the covering surface portion 281.

[0113] The support surface portion 14 is formed to dimensions that allow it to be accommodated inside the pen case 320. The structure of the support surface portion 14 is the same as that of the support surface portion 14 described with reference to Figures 1 and 2A.

[0114] A first retaining portion 16 and a second retaining portion 18 are formed on the support surface 15a of the support surface portion 14. The first retaining portion 16 and the second retaining portion 18 are configured in the same way as the first retaining portion 16 and the second retaining portion 18 described with reference to Figures 1 and 2A.

[0115] As shown in Figure 29, the first strip-shaped sheet 17, which constitutes the first holding portion 16, and the second strip-shaped sheet 26, which constitutes the second holding portion 18, are sewn to the lower surface 15b of the support surface portion 14. One end of the connecting portion 283 is sewn into the piping section of the lower surface 15b to join them.

[0116] The covering surface portion 281 is a plate-shaped member having the same planar shape as the support surface portion 14, and is formed to be approximately the same dimensions as the support surface portion 14. The covering surface portion 281 has a relatively hard plate-shaped core material, a surface material that covers the surface of the core material, and a piping section that wraps around the end of the surface material at its periphery. The other end of the connecting portion 283 is sewn into and joined to the piping section of the covering surface portion 281.

[0117] The covering surface portion 281 has an upper surface 281a that appears as a surface facing the same direction as the support surface 15a of the support surface portion 14 when the pen holder 280 is spread out flat, and a lower surface 281b (see Figure 29) that appears on the opposite side. Two mesh pockets 259 are provided side by side along the long side of the lower surface 281b of the covering surface portion 281. The mesh pockets 259 are pocket-shaped storage portions formed by sewing mesh fabric to the covering surface portion 281.

[0118] The connecting portion 283 is a flexible, strip-shaped member, formed from, for example, fabric. One end of the connecting portion 283 is joined to the support surface portion 14, and the other end is joined to the covering surface portion 281.

[0119] As shown in Figure 30, the pen holder 280 having a connecting portion 283 can fold its covering surface portion 281 below the lower surface 15b of the support surface portion 14. This arrangement makes the writing instrument 12 housed on the support surface 15a of the support surface portion 14 visible. As a result, the pen holder 280 can hold the writing instrument 12 in a viewable state.

[0120] Furthermore, as shown in Figure 31, the pen holder 280 can also cover the upper part of the support surface 15a of the support surface 14 with its covering surface 281. By covering the support surface 15a, the covering surface 281 can conceal the writing instrument 12.

[0121] As shown in Figures 32 and 33, the pen holder 280 of this embodiment is used by being housed in a pen case 320. The pen case 320 of this embodiment is configured similarly to the pen case 100 of the third embodiment, except that its width is narrower. In the pen case 320, components similar to those in the pen case 100 are given the same reference numerals, and their detailed descriptions are omitted. Because the storage space of the pen case 320 is limited, it does not have a connecting structure to secure the pen holder 280 to the pen case 320. This configuration allows the pen holder 280 having a covered surface portion 281 to be smoothly housed in the pen case 320, which has limited storage space. This allows the pen holder 280 having a covered surface portion 281 to be suitably housed inside the narrow pen case 320.

[0122] (Seventh Embodiment) This embodiment relates to a modified pen holder 340, as shown in Figure 34. In the pen holder 340 of this embodiment, components similar to those in the pen holder 10 of the first embodiment are denoted by the same reference numerals, and their detailed description is omitted.

[0123] The pen holder 340 comprises a support surface 14 and a pair of second holding parts 18. The support surface 14 is configured in the same way as the support surface 14 of the first embodiment. The pair of second holding parts 18 are provided on the support surface 15a. One second holding part 18 and the other second holding part 18 are spaced apart in the longitudinal direction of the pen holder 340.

[0124] The structure of the second holding part 18 is configured in the same way as the second holding part 18 of the first embodiment (see Figures 1 and 2B). The widthwise position of the second cylindrical part 28 of one second holding part 18 is positioned at approximately the same widthwise position as the widthwise position of the second cylindrical part 28 of the other second holding part 18. One second holding part 18 restricts the widthwise displacement of the writing instrument 12 near the first end. The other second holding part 18 restricts the widthwise displacement of the writing instrument 12 near the second end.

[0125] In this embodiment, the pen holder 340 can prevent the writing instrument 12 from detaching from the support surface 14 by, for example, covering the upper part of the support surface 15a of the support surface 14 with the lid of a pen case (not shown). The pen holder 340 of this embodiment can also hold the writing instrument 12 in a highly visible state while preventing damage due to displacement in the width direction of the writing instrument 12.

[0126] (Eighth embodiment) This embodiment relates to a pen holder 350 according to another modification, as shown in Figure 35. In the pen holder 350 of this embodiment, components similar to those in the pen holder 10 of the first embodiment are denoted by the same reference numerals, and their detailed description is omitted.

[0127] The pen holder 350 of this embodiment comprises a support surface portion 14 and a second holding portion 18. The support surface portion 14 is configured in the same way as the support surface portion 14 of the first embodiment. The second holding portion 18 has the same structure as the second holding portion 18 of the first embodiment.

[0128] In this embodiment, the second holding portion 18 is positioned near the center of the pen holder 350 in the longitudinal direction. In this embodiment, the pen holder 350 can restrict the overall displacement of the writing instrument 12 in the width direction, including the first and second ends, by holding the writing instrument 12 near its center with the second holding portion 18.

[0129] In this embodiment, the pen holder 350 can prevent the writing instrument 12 from detaching from the support surface 14 by, for example, covering the area above the support surface 15a of the support surface 14 with the lid of a pen case (not shown). Therefore, the pen holder 350 of this embodiment can also hold the writing instrument 12 in a highly visible state while preventing damage due to displacement in the width direction of the writing instrument 12.

[0130] With regard to the above embodiments, the following additional information is disclosed.

[0131] (Note 1) The pen holders (10, 280, 340, 350) of this disclosure are pen holders for holding a plurality of writing instruments (12) arranged in the width direction, and include a support surface portion (14) having a support surface (15a) for supporting the writing instruments, and a second holding portion (18) positioned on the support surface and gripping the sides of the writing instruments to restrict their displacement in the width direction, wherein the second holding portion has a plurality of second cylindrical portions (28) through which the writing instruments cannot be inserted, and the second cylindrical portions abut the sides of the writing instruments to restrict their displacement in the width direction.

[0132] The pen holder described above can prevent damage caused by contact with the writing instrument. Furthermore, since the second cylindrical part only touches the side of the writing instrument and does not cover the front, the visibility of the writing instrument's appearance is excellent.

[0133] (Note 2) The pen holder described in Appendix 1 may have a holding space for holding the writing instrument formed between the second cylindrical parts. This pen holder can hold the writing instrument between the second cylindrical parts.

[0134] (Note 3) The pen holder described in Appendix 1 or 2, wherein the second holding portion has a second strip-shaped sheet (26) extending in the width direction, and the second cylindrical portion is formed by folding the second strip-shaped sheet and has a second joining portion (30) to which the base portion (28a) of the second cylindrical portion is joined to the support surface portion. This pen holder is suitable because it has a simple structure, allows for good visibility of the writing instrument, and prevents damage. Furthermore, since the second holding portion can be manufactured using the same process as the first holding portion, such as folding and sewing a strip-shaped sheet, complex sewing processes are unnecessary, resulting in excellent production efficiency.

[0135] (Note 4) The pen holder described in Appendix 3 may have a flat portion (36) along the support surface between one adjacent second cylindrical portion and the other adjacent second cylindrical portion. In this pen holder, the writing instrument can be placed on the flat portion to fit neatly into the second holding portion.

[0136] (Note 5) The pen holder described in any one of the appendices 1 to 4 may further have a first retaining portion (16) provided on the support surface that covers the periphery of the writing instrument to prevent it from detaching from the support surface. This pen holder, having a structure in which the first retaining portion covers the periphery of the writing instrument, can prevent the writing instrument from detaching from the support surface, and in combination with the second retaining portion, can securely hold the writing instrument on the support surface.

[0137] (Note 6) In the pen holder described in Appendix 5, the position in the width direction of at least a portion of the second cylindrical portion may be positioned offset from the center position (34) in the width direction of the first holding portion. Such an arrangement between the first holding portion and the second holding portion is suitable for holding a writing instrument aligned in the longitudinal direction.

[0138] (Note 7) The pen holder described in Appendix 5 or 6, wherein the first holding portion has a first strip-shaped sheet (17) extending in the width direction, and the first strip-shaped sheet may have a plurality of first cylindrical portions (20) that are curved away from the support surface portion and through which the writing instrument is inserted, and a plurality of first joining portions (24) located on both sides of the first cylindrical portions and sewn to the support surface portion. Since the first cylindrical portions can be formed by sewing the first strip-shaped sheet together, the structure of this pen holder is simplified and it can be manufactured at low cost.

[0139] (Note 8) The pen holder described in Appendix 7 may have the widthwise position of the second cylindrical portion coincide with the widthwise position of the first joint portion. This pen holder offers excellent usability because the writing instrument inserted through the first cylindrical portion can be easily placed in the second holding portion.

[0140] (Note 9) The pen holder (280) described in any one of the appendices 1 to 8 may include a flexible connecting portion (283) connected to the side of the support surface portion, and a covering surface portion (281) capable of covering at least a part of the support surface portion of the support surface portion via the connecting portion. This pen holder can conceal a writing instrument by placing the covering surface portion on the support surface portion of the support surface portion.

[0141] (Note 10) Another aspect of this disclosure is a pen case (40, 100, 150, 200, 320) having a pen holder as described in any one of Appendices 1 to 9. Because this pen case has the above-described pen holder, it can prevent damage to writing instruments while maintaining their readability.

[0142] (Note 11) The pen case described in Appendix 10 comprises a first main body portion (50, 106, 156), a first hinge portion (56, 110, 160) provided at one end of the first main body portion, a second main body portion (52, 108, 158) pivotably connected to the first main body portion via the first hinge portion and facing the first main body portion to form a first storage chamber (44, 104, 154) capable of accommodating the writing instrument, and a first fastener (42, 102, 152) extending along the periphery of the first main body portion and the periphery of the second main body portion to open and close the first storage chamber, wherein the pen holder may be formed on the inner surface of the first main body portion or the second main body portion. By providing the above-mentioned pen holder on the inner surface of the main body portion of this pen case, the readability of the writing instrument can be improved.

[0143] (Note 12) The pen case described in Appendix 11 further comprises a plate-shaped first pivotable partition plate (72, 130, 180) pivotably joined to the first or second main body via a second hinge portion (86, 144, 192), wherein the first pivotable partition plate may be capable of covering the upper part of the support surface. This pen case can more effectively prevent damage to writing instruments by covering them with the first pivotable partition plate.

[0144] (Note 13) The pen case described in Appendix 12 further comprises a plate-shaped second pivotable partition plate (74, 182, 204) pivotably joined to the first or second main body via a third hinge portion (88, 194, 232), wherein the second pivotable partition plate has the pen holder formed thereon, and the first pivotable partition plate may be positioned between the pen holder of the second pivotable partition plate and the pen holder provided on the inner surface of the first or second main body. This pen case offers excellent storage capacity because writing instruments can also be stored in the second pivotable partition plate. Furthermore, the first pivotable partition plate prevents writing instruments stored in the pen case from coming into contact with each other, effectively preventing damage to the writing instruments.

[0145] (Note 14) The pen case described in Appendix 10 comprises: a first main body portion (106, 156, 206); a first hinge portion (110, 160, 214) provided at one end of the first main body portion; a second main body portion (108, 158, 208) pivotably connected to the first main body portion via the first hinge portion and facing the first main body portion to form a first storage chamber (104, 154, 212) capable of accommodating the writing instrument; a first fastener (102, 152, 210) extending along the periphery of the first main body portion and the periphery of the second main body portion to open and close the first storage chamber; and a second pivotable partition plate pivotably connected to the second main body portion via a third hinge portion, wherein the second pivotable partition plate may have the pen holder on the side facing the first main body portion. Because this pen case has the aforementioned pen holder on the second pivoting divider plate, it can prevent damage to writing instruments without impairing their visibility.
