Summary of the Invention

Problems to be Solved by the Invention

[0005] In the above-described bedding pillow, since each of the upper pillow and the lower pillow has a partition chamber, it becomes relatively thick when filled with items. Therefore, the bedding pillow may be difficult to wash and may also be difficult to dry even after washing. Thus, it is required to be easy to wash and easy to dry.

[0006] An object of this disclosure is to provide a pillow that is easy to wash and easy to dry.

Means for Solving the Problems

[0007] (1) The pillow according to the present disclosure comprises an outer bag having an outer fabric and a lining, which is closed by folding the outer fabric against the lining and opened by opening the outer fabric against the lining, and a plurality of inner bags disposed inside the outer bag and having a plurality of pockets from which filling can be inserted and removed. At least one of the plurality of inner bags is detachable from the outer bag when the outer bag is open.

[0008] This pillow has an outer bag with an outer fabric and an inner lining. The outer bag is closed by folding the outer fabric against the inner lining and opened by unfolding the outer fabric against the inner lining. Thus, the outer bag is openable and closable. The pillow has multiple inner bags placed inside the outer bag. Each of the multiple inner bags has multiple pockets into which filling can be added or removed. Therefore, the height of the pillow can be freely changed by adjusting the amount of filling placed in each of the multiple pockets, allowing the pillow to be set to a preferred height. Furthermore, at least one of the multiple inner bags is detachable from the outer bag. Therefore, at least one of the multiple inner bags can be separated from the outer bag, allowing the inner bags to be removed and washed. Thus, since the inner bags can be washed separately from the outer bag, the pillow can be made easy to wash and dry.

[0009] (2) In (1) above, the multiple inner bags may be a first inner bag located on the outer fabric and a second inner bag located on the lining in the open outer bag. Either the first inner bag or the second inner bag may be detachable from the outer bag, or the other of the first inner bag or the second inner bag may not be detachable from the outer bag. In this case, either the first inner bag or the second inner bag can be removed from the outer bag for washing, and the other can be washed together with the outer bag. Thus, because the pillow can be disassembled into two parts, the outer bag and inner bags can be easily managed.

[0010] (3) In (1) or (2) above, the inner bag which is detachable from the outer bag may have a bottom surface which rests on the top surface of the open outer bag, and at least one of the top surface and the bottom surface may be a non-slip surface. In this case, the inner bag which is detachable from the outer bag can be made less likely to slip relative to the outer bag, so that the shifting of the inner bag relative to the outer bag can be suppressed. Therefore, the comfort of the pillow and the comfort of sleeping can be improved.

[0011] (4) In any of (1) to (3) above, the inner bag which is detachable from the outer bag may have a gusset located on its outer edge. In this case, the height of the inner bag located inside the outer bag can be maintained by the gusset.

[0012] (5) In (4) above, the inner bag which is detachable from the outer bag may be rectangular in shape, having a first short side, a second short side opposite to the first short side, a first long side connecting one end of the first short side and the second short side to each other, and a second long side opposite to the first long side. The gusset may include a first gusset provided on the first short side, the second short side, and the first long side, and a second gusset provided on the second long side. The second gusset may be provided at each of the ends of the second long side. The width of the second gusset may decrease as it moves away from both ends of the second long side. In this case, by positioning the inner bag with the second long side facing the center in the longitudinal direction of the outer bag when the outer bag is opened, the second gusset can be made less likely to get in the way when closing the outer bag. Therefore, the outer bag can be opened and closed easily, and the inner bag can be inserted and removed smoothly. [Effects of the Invention]

[0013] According to this disclosure, it is possible to provide a pillow that is easy to wash and easy to dry. [Brief explanation of the drawing]

[Figure 3] Figure 3 is a perspective view showing the outer bag of the pillow from Figure 1 in an open state. [Figure 4] Figure 4 is a schematic plan view showing the pillow bag from Figure 1 in an open state. [Figure 5] Figure 5 is a perspective view showing the inner lining of the pillow shown in Figure 1. [Figure 6] Figure 6 is a perspective view of the inner bag shown in Figure 5, viewed from the opposite direction to Figure 5. [Figure 7] Figure 7 is a perspective view showing the top surface of the outer bag with the inner bag removed, as shown in Figure 5. [Figure 8] Figure 8 is a perspective view showing the gusset portion of the inner bag shown in Figure 5. [Modes for carrying out the invention]

[0015] The embodiments of the pillow according to this disclosure will be described below with reference to the drawings. In the description of the drawings, the same or corresponding elements will be denoted by the same reference numeral, and redundant explanations will be omitted as appropriate. For the sake of ease of understanding, the drawings may be simplified or exaggerated in some parts, and the dimensional ratios, etc., are not limited to those shown in the drawings.

[0016] Figure 1 is a perspective view showing the pillow 1 according to this embodiment. Figure 2 is a plan view showing the pillow 1. As shown in Figures 1 and 2, the pillow 1 is rectangular in shape, having a first short side 1d and a second short side 1f extending in a first direction D1, and a first long side 1b and a second long side 1c extending in a second direction D2 perpendicular to the first direction D1. The pillow 1 has thickness in a third direction D3 that intersects the first direction D1 and the second direction D2.

[0017] Pillow 1 has an outer fabric 2 and a lining 3 opposite to the outer fabric 2. Both the outer fabric 2 and the lining 3 are rectangular in shape. For example, the outer fabric 2 and the lining 3 are made of different types of fabric. In this case, the user of pillow 1 can experience different sleeping sensations by either having the outer fabric 2 on top or the lining 3 on top, according to their preference.

[0018] For example, one of the surface fabric 2 and the back fabric 3 is made of knit, and the other of the surface fabric 2 and the back fabric 3 is made of hemp (or double jersey). One of the surface fabric 2 and the back fabric 3 may be made of a contact-cooling feeling fabric. In this case, the user of the pillow 1 can feel a cool sleeping comfort by sleeping with the contact-cooling feeling fabric facing up.

[0019] The pillow 1 has a central region 2b located at the center in the second direction D2 corresponding to the longitudinal direction of the pillow 1, a first side region 2c located in the second direction D2 of the central region 2b, and a second side region 2d located on the side opposite to the first side region 2c when viewed from the central region 2b. The first side region 2c and the second side region 2d bulge with respect to the central region 2b. The first long side 1b of the pillow 1 is curved so as to be concave inside the pillow 1 in a plan view in the central region 2b. The second long side 1c of the pillow 1 extends linearly along the second direction D2.

[0020] The pillow 1 is openable and closable about the first long side 1b. FIG. 3 is a perspective view showing the opened pillow 1. As shown in FIGS. 1, 2 and 3, the pillow 1 has a wire fastener 4 that enables the pillow 1 to be opened and closed. The wire fastener 4 extends along the first short side 1d, the second long side 1c and the second short side 1f. In a plan view (when viewed along the third direction D3), the wire fastener 4 is U-shaped.

[0021] The pillow 1 has an outer bag 1A that constitutes the surface of the pillow 1 and an inner bag group 1B that is located inside the outer bag 1A when the pillow 1 is closed. The inner bag group 1B includes a plurality of inner bags. The outer bag 1A has the surface fabric 2 and the back fabric 3 described above. The outer bag 1A is closed by folding the surface fabric 2 over the back fabric 3. The outer bag 1A is opened by opening the surface fabric 2 with respect to the back fabric 3. The outer bag 1A is closed by closing the wire fastener 4 in a state where the surface fabric 2 is folded over the back fabric 3. In this state, the pillow 1 can be used.

[0022] Figure 4 is a plan view showing the outer bag 1A in an open state. As shown in Figures 3 and 4, for example, the outer bag 1A is oriented downwards when open. At this time, the inner bag group 1B is oriented upwards. When open, the outer bag 1A has a rectangular shape with a long side extending in a first direction D1 and a short side extending in a second direction D2.

[0023] In this embodiment, the multiple inner bags are a first inner bag 5 and a second inner bag 6. The first inner bag 5 is attached to the inside of the outer fabric 2, and the second inner bag 6 is attached to the inside of the lining 3. That is, when the outer bag 1A is open, the first inner bag 5 is located on top of the outer fabric 2, and the second inner bag 6 is located on top of the lining 3. Therefore, when the outer bag 1A is closed, the first inner bag 5 and the outer fabric 2 are placed on top of the lining 3 and the second inner bag 6. At this time, the first inner bag 5 is located on top of the second inner bag 6.

[0024] The first inner bag 5 and the second inner bag 6 are each placed inside the outer bag 1A. Each of the first inner bag 5 and the second inner bag 6 has multiple pockets into which stuffing can be inserted and removed. The pockets will be described in detail later. At least one of the first inner bag 5 and the second inner bag 6 is detachable from the outer bag 1A when the outer bag 1A is open.

[0025] For example, either the first inner bag 5 or the second inner bag 6 is detachable from the outer bag 1A, while the other of the first inner bag 5 or the second inner bag 6 is not detachable from the outer bag 1A. In this embodiment, the first inner bag 5 is not detachable from the outer bag 1A, and the second inner bag 6 is detachable from the outer bag 1A. The second inner bag 6 corresponds to the inner bag that is detachable from the outer bag 1A.

[0026] The first inner bag 5 is fixed to the inner surface of the outer fabric 2 (the upper surface of the outer fabric 2 in the opened outer bag 1A) by, for example, sewing. This makes the first inner bag 5 irremovable from the outer fabric 2. The first inner bag 5 is rectangular in shape, with a short side extending along the first direction D1 and a long side extending along the second direction D2.

[0027] The first inner bag 5 has a string-like portion 5w that protrudes outward from the open outer bag 1A. The string-like portion 5w is a hook that can be attached to clothespins or the like. The string-like portion 5w makes it easy to dry the washed outer bag 1A and the first inner bag 5. One end and the other end of the string-like portion 5w are fixed to the outer edge of the first inner bag 5 in a plan view by sewing, and the string-like portion 5w extends in a U-shape from the outer edge of the first inner bag 5. The first inner bag 5 has multiple string-like portions 5w, which are arranged along the long side of the first inner bag 5. For example, the first inner bag 5 has three string-like portions 5w. For example, the first inner bag 5 has a tag 5x on which information about the first inner bag 5 is written.

[0028] The first inner bag 5 has multiple pockets. The multiple pockets of the first inner bag 5 are separated from each other, and it is possible to put filling into and take out of each of the multiple pockets. The multiple pockets of the first inner bag 5 are filled with a filling that is less fluid and more flexible than the filling that is stored in the multiple pockets of the second inner bag 6. For example, granular cotton is placed in the multiple pockets of the first inner bag 5.

[0029] In this embodiment, the first inner bag 5 has seven pocket sections. In this case, the multiple pocket sections of the first inner bag 5 are pocket section 5b, pocket section 5c, pocket section 5d, pocket section 5f, pocket section 5g, pocket section 5h, and pocket section 5j. Pocket sections 5b, 5c, and 5d are located in the center of the second direction D2, which is the longitudinal direction of the first inner bag 5.

[0030] Pocket sections 5d, 5c, and 5b are arranged in this order along the first direction D1, which is the shorter direction of the first inner bag 5. Pocket section 5b has a zipper 5k, pocket section 5c has a zipper 5p, and pocket section 5d has a zipper 5q. With zippers 5k, 5p, and 5q open, stuffing can be inserted into and removed from pocket sections 5b, 5c, and 5d, respectively.

[0031] Pocket sections 5f and 5g are located in the second direction D2 relative to pocket sections 5b, 5c, and 5d. Pocket sections 5g and 5f are arranged in this order along the first direction D1. Pocket section 5f has a zipper 5r, and pocket section 5g has a zipper 5s. With zippers 5r and 5s respectively open, stuffing can be inserted into and removed from pocket sections 5f and 5g, respectively.

[0032] Pocket sections 5h and 5j are located in the opposite direction to the second direction D2 of pocket sections 5b, 5c, and 5d. Pocket sections 5j and 5h are arranged in this order along the first direction D1. Pocket section 5h has a zipper 5t, and pocket section 5j has a zipper 5v. With zippers 5t and 5v open, stuffing can be inserted into and removed from pocket sections 5h and 5j, respectively.

[0033] The first inner bag 5 has been described above. As mentioned earlier, for example, each of the multiple pockets of the first inner bag 5 contains granular cotton. The first inner bag 5 is not removable from the outer bag 1A, while the second inner bag 6 is removable from the outer bag 1A. Therefore, it is possible to separate the second inner bag 6 from the outer bag 1A and wash and dry the outer bag 1A to which the first inner bag 5 is attached, and the second inner bag 6 separately.

[0034] Figure 5 is a perspective view showing the second inner bag 6 after it has been removed from the outer bag 1A. Figure 6 is a perspective view showing the second inner bag 6 from the opposite direction to that shown in Figure 5. As shown in Figures 4, 5, and 6, the second inner bag 6 is rectangular in shape, having a first short side 6b1 and a second short side 6b2 extending along the first direction D1, and a first long side 6b3 and a second long side 6b4 extending along the second direction D2.

[0035] The second inner bag 6 does not have, for example, a string-like portion that protrudes outward (the aforementioned string-like portion 5w). In this case, the shape of the second inner bag 6 can be simplified. However, the second inner bag 6 may have a string-like portion similar to the string-like portion 5w of the first inner bag 5. In this case, the second inner bag 6 can be easily dried.

[0036] For example, the second inner bag 6 has a tag 6x on which information about the second inner bag 6 is written. The second inner bag 6 has a first short side 6b1, a second short side 6b2 opposite to the first short side 6b1, a first long side 6b3 connecting one end each of the first short side 6b1 and the second short side 6b2, and a second long side 6b4 opposite to the first long side 6b3.

[0037] In the opened outer bag 1A, the second inner bag 6 is positioned so that its second long side 6b4 is adjacent to the first inner bag 5. For example, the tag 6x is attached to the first short side 6b1 of the second inner bag 6. As an example, the tag 6x is positioned so as to be aligned with the tag 5x of the first inner bag 5 along the first direction D1. In this case, the orientation of the second inner bag 6 relative to the opened outer bag 1A can be easily understood.

[0038] The second inner bag 6 has multiple pocket sections. The multiple pocket sections of the second inner bag 6 are separated from each other, and it is possible to put filling material into and out of each of the multiple pocket sections. For example, the multiple pocket sections of the second inner bag 6 are filled with a filling material that is more fluid and less flexible than the filling material that is stored in the multiple pocket sections of the first inner bag 5.

[0039] As an example, hollow granular material can be placed in the multiple pockets of the second inner bag 6. The hollow granular material is, for example, pipe material. When granular cotton is placed in the multiple pockets of the first inner bag 5 and hollow granular material is placed in the multiple pockets of the second inner bag 6, the height of the pillow 1 can be maintained in the second inner bag 6, and the user can feel the softness of the pillow 1 in the first inner bag 5.

[0040] In this embodiment, the second inner bag 6 has seven pocket sections. In this case, the multiple pocket sections of the second inner bag 6 are pocket section 6b, pocket section 6c, pocket section 6d, pocket section 6f, pocket section 6g, pocket section 6h, and pocket section 6j. Pocket sections 6b, 6c, and 6d are located in the center of the second direction D2, which is the longitudinal direction of the second inner bag 6.

[0041] Pocket sections 6b, 6c, and 6d are arranged in this order along the first direction D1, which is the shorter direction of the second inner bag 6. Pocket section 6b has a zipper 6k, pocket section 6c has a zipper 6p, and pocket section 6d has a zipper 6q. With zippers 6k, 6p, and 6q open, stuffing can be inserted into and removed from pocket sections 6b, 6c, and 6d, respectively.

[0042] Pocket sections 6f and 6g are located in the second direction D2 relative to pocket sections 6b, 6c, and 6d. Pocket sections 6f and 6g are arranged in this order along the first direction D1. Pocket section 6f has a zipper 6r, and pocket section 6g has a zipper 6s. With zippers 6r and 6s respectively open, stuffing can be inserted into and removed from pocket sections 6f and 6g, respectively.

[0043] Pocket sections 6h and 6j are located in the opposite direction to the second direction D2 of pocket sections 6b, 6c, and 6d. Pocket sections 6h and 6j are arranged in this order along the first direction D1. Pocket section 6h has a zipper 6t, and pocket section 6j has a zipper 6v. With zippers 6t and 6v open, stuffing can be inserted into and removed from pocket sections 6h and 6j, respectively.

[0044] Figure 7 is a perspective view showing the outer bag 1A in an open state with the second inner bag 6 removed. As shown in Figures 6 and 7, the second inner bag 6 has a lower surface 6b5 that rests on the upper surface 3b of the open outer bag 1A (lining 3). At least one of the upper surface 3b and the lower surface 6b5 is a non-slip surface. That is, at least one of the upper surface 3b and the lower surface 6b5 is made of a non-slip fabric.

[0045] In this embodiment, the upper surface 3b and the lower surface 6b5 are made of a non-slip fabric. Specifically, one of the upper surface 3b and the lower surface 6b5 is a hook fabric, and the other is a loop fabric. In this case, when the lower surface 6b5 of the second inner bag 6 is placed on the upper surface 3b of the outer bag 1A, the hooks catch on the loops, making it difficult for the second inner bag 6 to shift.

[0046] In particular, the second inner bag 6 can be made less likely to shift in the first direction D1 and the second direction D2. Therefore, it is possible to prevent the second inner bag 6 from shifting inside the pillow 1 and causing discomfort to the user of the pillow 1. The upper surface 3b and the lower surface 6b5 may be made of a material other than microfiber. In this case, the upper surface 3b and the lower surface 6b5 can be made heat resistant.

[0047] Figure 8 is an enlarged perspective view of a portion of the second inner bag 6 shown in Figure 6. As shown in Figures 6 and 8, the second inner bag 6 has a gusset portion 6z located on its outer edge. The presence of the gusset portion 6z in the second inner bag 6 allows the second inner bag 6 to have height (thickness) when stuffing is placed in the multiple pockets of the second inner bag 6.

[0048] The gusset portion 6z includes a first gusset portion 6z1 provided on the first short side 6b1, second short side 6b2, and first long side 6b3 of the second inner bag 6, and a second gusset portion 6z2 provided on the second long side 6b4. The width of the first gusset portion 6z1 is constant. In contrast, the width of the second gusset portion 6z2 is variable.

[0049] The gusset portion 6z includes, for example, two second gusset portions 6z2. The second gusset portions 6z2 are provided at each of the ends of the second long side 6b4. "Both ends" refers to a certain area extending from both ends toward the center of something. The width of the second gusset portions 6z2 decreases from the ends of the second long side 6b4 toward the center of the second long side 6b4. Therefore, when stuffing is placed in the multiple pockets of the second inner bag 6, the height of the first long side 6b3 tends to be greater than that of the second long side 6b4.

[0050] Next, the effects obtained from the pillow 1 according to this embodiment will be described. As shown in Figure 3, the pillow 1 comprises an outer bag 1A having an outer fabric 2 and a lining 3. The outer bag 1A is closed by folding the outer fabric 2 against the lining 3 and opened by opening the outer fabric 2 against the lining 3. In this way, the outer bag 1A is openable and closable. The pillow 1 comprises a plurality of inner bags (first inner bag 5 and second inner bag 6) arranged inside the outer bag 1A. Each of the plurality of inner bags has a plurality of pockets into which filling can be inserted and removed. Therefore, by adjusting the amount of filling to be stored in each of the plurality of pockets, the height of the pillow 1 can be freely changed, and the height of the pillow 1 can be set to a preferred height.

[0051] Furthermore, at least one of the multiple inner bags (the second inner bag 6) is detachable from the outer bag 1A. Therefore, at least one of the multiple inner bags can be separated from the outer bag 1A, allowing the inner bags to be removed from the outer bag 1A and washed. Consequently, the inner bags can be washed separately from the outer bag 1A, resulting in a pillow 1 that is easy to wash and dry.

[0052] In this embodiment, the multiple inner bags are a first inner bag 5 located on the outer fabric 2 and a second inner bag 6 located on the lining 3 in the open outer bag 1A. Either the first inner bag 5 or the second inner bag 6 may be detachable from the outer bag 1A, or the other of the first inner bag 5 or the second inner bag 6 may not be detachable from the outer bag 1A. In this case, either the first inner bag 5 or the second inner bag 6 can be removed from the outer bag 1A for washing, while the other can be washed together with the outer bag 1A. Therefore, because the pillow 1 can be disassembled into two parts, the management of the outer bag 1A and the inner bags can be easily performed.

[0053] In this embodiment, the first inner bag 5, which is positioned on the outer fabric 2, is not detachable from the outer fabric 2, while the second inner bag 6, which is positioned on the lining 3, is detachable from the lining 3. Therefore, by fixing the first inner bag 5, which is located above the second inner bag 6, to the outer fabric 2, it is possible to reliably prevent the first inner bag 5, which is located closer to the user's head, from shifting inside the pillow 1.

[0054] As shown in Figures 6, 7, and 8, in this embodiment, the second inner bag 6, which is detachable from the outer bag 1A, has a lower surface 6b5 that rests on the upper surface 3b of the open outer bag 1A, and at least one of the upper surface 3b and the lower surface 6b5 is a non-slip portion. In this case, the second inner bag 6, which is detachable from the outer bag 1A, can be made less likely to slip relative to the outer bag 1A, thereby suppressing displacement of the second inner bag 6 relative to the outer bag 1A. Therefore, the comfort of using the pillow 1 and the comfort of sleeping can be improved.

[0055] In this embodiment, the second inner bag 6, which is detachable from the outer bag 1A, has a gusset portion 6z located at its outer edge. In this case, the height of the second inner bag 6, which is located inside the outer bag 1A, can be maintained by the gusset portion 6z.

[0056] In this embodiment, the second inner bag 6, which is detachable from the outer bag 1A, is rectangular in shape and has a first short side 6b1, a second short side 6b2 opposite to the first short side 6b1, a first long side 6b3 connecting one end of the first short side 6b1 and the second short side 6b2 to each other, and a second long side 6b4 opposite to the first long side 6b3. The gusset portion 6z includes a first gusset portion 6z1 provided on the first short side 6b1, the second short side 6b2, and the first long side 6b3, and a second gusset portion 6z2 provided on the second long side 6b4. The second gusset portion 6z2 is provided on each of the ends of the second long side 6b4. The width of the second gusset portion 6z2 decreases as it moves away from both ends of the second long side 6b4. In this case, by positioning the second inner bag 6 with its second long side 6b4 facing the center side (first inner bag 5 side) of the long side (for example, the first direction D1) of the open rectangular outer bag 1A, the second gusset portion 6z2 can be made less likely to get in the way when closing the outer bag 1A. Therefore, the outer bag 1A can be opened and closed easily, and the inner bag can be smoothly inserted into and removed from the outer bag 1A.

[0057] The embodiments of the pillow according to this disclosure have been described above. However, the pillow according to this disclosure is not limited to the embodiments described above, and may be modified within the scope of the gist described in the claims. That is, the shape, size, material, number, and arrangement of each part of the pillow can be changed as appropriate within the scope of the gist described above.

[0058] For example, in the embodiment described above, an example was described in which the first inner bag 5 is not detachable from the outer bag 1A, while the second inner bag 6 is detachable. However, the first inner bag 5 may be detachable from the outer bag 1A, while the second inner bag 6 is not. Furthermore, both the first inner bag 5 and the second inner bag 6 may be detachable from the outer bag 1A. Thus, the number and type of detachable inner bags from the outer bag 1A can be changed as appropriate.

[0059] In the embodiments described above, an example was given in which the second inner bag 6 has a gusset portion 6z. However, the first inner bag 5 may also have a gusset portion similar to the gusset portion 6z. In the embodiments described above, an example was given in which the gusset portion 6z includes two second gusset portions 6z2, each of which is provided at both ends of the second long side 6b4 of the second inner bag 6. However, the gusset portion 6z may include one second gusset portion 6z2 provided on the second long side 6b4, and the width of the second gusset portion 6z2 may decrease towards the center of the second long side 6b4. Thus, the number, shape, and arrangement of the second gusset portions 6z2 can be changed as appropriate. The same applies to the first gusset portion 6z1.

[0060] In the embodiment described above, an example was described in which granular cotton is contained in multiple pockets of the first inner bag 5, and hollow granular material is contained in multiple pockets of the second inner bag 6. However, the type of filling contained in the pockets of the first inner bag 5 and the type of filling contained in the pockets of the second inner bag 6 can be changed as appropriate.

[0061] In the embodiments described above, an example was described in which at least one of the upper surface 3b of the outer bag 1A and the lower surface 6b5 of the second inner bag 6 is a non-slip portion. However, the pillow may have a joint portion that connects the lower surface of the inner bag to the upper surface of the outer bag. The joint portion is, for example, a hook placed on the upper surface of the outer bag and the lower surface of the inner bag. In this way, even when the pillow has a joint portion, displacement of the inner bag located inside the outer bag can be suppressed.

[0062] In the embodiments described above, an example was described in which each of the first inner bag 5 and the second inner bag 6 has seven pocket sections. However, each of the first inner bag and the second inner bag may have eleven pocket sections. Thus, the number and arrangement of pocket sections in the inner bag can be changed as appropriate.
