Summary of the Invention

Problems to be Solved by the Invention

[0004] The pillow of Patent Document 1 is filled with urethane chips to improve breathability. In such a pillow, it is preferable to fill chips having a breathable shape. Patent Document 1 does not disclose such a point. The problem of this disclosure is to provide a novel pillow.

Means for Solving the Problems

[0005] A pillow according to one aspect of this disclosure includes a first bag body made of fiber and a plurality of chip members filled in the first bag body. The chip members are formed of a foam having at least two surfaces with substantially the same distance from each other.

[0006] According to this pillow, the first bag is filled with chip members formed of a foam. The chip members have at least two surfaces with substantially the same distance from each other. Thereby, the first bag body is filled with chip members having a generally uniform shape. For this reason, the first bag body can be washed with water and can prevent unevenness in breathability from occurring. As a result, the pillow can improve breathability.

Effects of the Invention

[0007] According to this disclosure, a new type of pillow can be provided. [Brief explanation of the drawing]

[0008] [Figure 1] A plan view showing the state of use of the pillow in the embodiment of this disclosure. [Figure 2] A plan view of a pillow in the embodiment of this disclosure. [Figure 3] A cross-sectional view showing section AA in Figure 2. [Figure 4] A cross-sectional view showing the BB cross-section in Figure 2. [Figure 5] A perspective view showing a schematic of the chip member in the embodiment of the present disclosure. [Modes for carrying out the invention]

[0009] The embodiments of this disclosure will be described below with reference to the drawings. In Figures 1 and 2, the vertical direction H is defined as the top of the page being the upper side and the bottom being the lower side. The width direction W is defined as the right side being the right side and the left side being the left side.

[0010] Furthermore, in Figures 3 and 4, the thickness direction T is defined as the upper side being the top of the paper and the lower side being the bottom. When pillow 1 is in use, the thickness direction T roughly coincides with the direction of gravity. Also, the vertical direction H is defined as the lower side being the right of the paper and the upper side being the left.

[0011] As shown in Figures 1 and 2, in the embodiment of the present disclosure, the pillow 1 is positioned so that the user M's head is located near the center in the vertical direction H and the width direction W. The pillow 1 comprises a first bag 2, a second bag 4, urethane chips (an example of chip material) 6, and a cover 8.

[0012] The first bag 2 is made of fibers containing cotton and / or polyester. In this embodiment, the first bag 2 is formed of a blend of fibers consisting of 35% cotton and 65% polyester. Alternatively, the first bag 2 may be made of cotton alone or polyester alone. In addition, the first bag 2 may be formed using a variety of fibers.

[0013] The first bag body 2 has a longitudinal direction 21 and a transverse direction 22. The longitudinal direction 21 extends generally along the width direction W. The transverse direction 22 extends generally along the vertical direction H. The longitudinal direction 21 and the transverse direction 22 should be of a size that allows the user M's head to be stably positioned near the center. In this embodiment, the longitudinal direction 21 is formed to be approximately 50 cm to 60 cm in size. Furthermore, the size of the longitudinal direction 21 may be 45 cm to 70 cm. Also, the transverse direction 22 is formed to be approximately 30 cm to 40 cm in size. Furthermore, the size of the transverse direction 22 may be 25 cm to 50 cm.

[0014] As shown in Figures 2, 3, and 4, the first bag 2 further includes a front member 23, a back member 24, and a slit 25. The front member 23 is the front surface that comes into contact with the user M's head when the pillow 1 is in use. The back member 24 is the surface opposite to the front member 23. The front member 23 and the back member 24 are generally the same shape and are joined together by sewing their edges together around the entire circumference. As a result, the first bag 2 has a bag shape with a space D between the front member 23 and the back member 24. However, the first bag 2 may also be formed by folding and sewing a portion of a continuous fibrous material beforehand. Various other adhesives may be used to bond the front member 23 and the back member 24.

[0015] The slit 25 connects the front member 23 and the back member 24. In this embodiment, the slit 25 is formed by simultaneously sewing the front member 23 and the back member 24 together in the thickness direction T, which intersects the vertical direction H and the width direction W. Specifically, the front member 23 and the back member 24 are placed overlapping in the thickness direction T and then sewn together simultaneously. As a result, the slit 25 is formed in a state where the front member 23 and the back member 24 are in close contact without any gaps in the thickness direction T. Consequently, when the urethane chips 6, which will be described later, are filled into the first bag 2, the size of the slit 25 in the thickness direction T becomes smaller than that of other parts.

[0016] Not limited to this, the slit 25 may be adhered by applying an adhesive or the like between the front member 23 and the back member 24, for example. Further, the front member 23 and the back member 24 may be connected via a thread inside the first bag body 2. At this time, the length of the thread connecting the front member 23 to the back member 24 in the thickness direction T is formed shorter than the size in the thickness direction T of the first bag body 2 filled with the urethane chip 6. Thereby, in the state where the urethane chip 6 is filled in the first bag body 2, the size of the slit 25 in the thickness direction T can be made smaller than other portions.

[0017] The plurality of slits 25 extend along the longitudinal direction 21. The plurality of slits 25 are the first slit 26 and the second slit 27.

[0018] The first slit 26 has a linear shape arranged along the longitudinal direction 21, that is, along the width direction W. The first slit 26 is formed larger than the head of the user M in the width direction W. In the present embodiment, the first slit 26 is formed to have a size of approximately 30 cm to 40 cm in the width direction W. Further, the size of the first slit 26 in the width direction W may be 20 cm to 50 cm. Thereby, when the head of the user M is placed on the pillow 1, the vicinity of the center of the occipital region is stably arranged in the first slit 26. For this reason, the user M can use the pillow 1 in a stable state without particularly adjusting the position of the pillow 1 and the head.

[0019] The second slit 27 is linear and arranged along the longitudinal direction 21, that is, along the width direction W. That is, the first slit 26 and the second slit 27 are arranged substantially parallel to the width direction W. The second slit 27 is formed shorter than the first slit 26 in the width direction W. Further, the second slit 27 is formed larger than the base of the user M's neck, that is, near the nape, in the width direction W. In the present embodiment, the second slit 27 is formed to be approximately 15 cm to 20 cm in size in the width direction W. Further, the size of the second slit 27 in the width direction W may be 10 cm to 30 cm. Thereby, when the head of the user M is placed on the pillow 1, the vicinity of the center of the user M's neck is stably arranged in the second slit 27. For this reason, the user M can use the pillow 1 in a stable state without particularly adjusting the position of the pillow 1 and the head.

[0020] Further, the first slit 26 and the second slit 27 are arranged at an interval L in the vertical direction H. That is, the plurality of slits 25 are arranged at an interval L along the short-side direction 22. The interval L is formed to be approximately equal to the length from the back of the head of the user M to near the nape in the vertical direction H. Therefore, in the first bag body 2, the first slit 26 and the second slit 27 are arranged at an interval L in accordance with the shape of the head of the user M. Thereby, in the pillow 1, a recessed portion having a smaller size in the thickness direction T than other portions is formed in accordance with the curve of the back of the head of the user M. As a result, the user M can use the pillow 1 in a stable state without particularly adjusting the position of the pillow 1 and the head.

[0021] The second bag body 4 is made of fibers containing cotton and / or polyester. In the present embodiment, the second bag body 4 is formed of a mixed fiber of 35% cotton and 65% polyester, similar to the first bag body 2. Further, the second bag body 4 may be formed of the same type of fiber as the first bag body 2, or may be formed of other types of fibers. Not limited to this, the second bag body 4 may be formed by applying various fibers.

[0022] The second bag 4 has a longitudinal direction 41 and a transverse direction 42. The longitudinal direction 41 extends generally along the width direction W. The transverse direction 42 extends generally along the vertical direction H. That is, the second bag 4 has a roughly rectangular shape in plan view. The longitudinal direction 41 and transverse direction 42 are formed to be approximately 1 / 2 to 1 / 3 the size of the longitudinal direction 21 and transverse direction 22 of the first bag 2. In this embodiment, the longitudinal direction 41 is formed to be approximately 15 cm to 25 cm in size. Furthermore, the size of the longitudinal direction 41 may be 10 cm to 30 cm. Also, the transverse direction 42 is formed to be approximately 15 cm to 25 cm in size. Furthermore, the size of the transverse direction 42 may be 10 cm to 30 cm.

[0023] The second bag 4 further comprises a front member 43 and a back member 44. The front member 43 is the front surface that comes into contact with the user M's head when the pillow 1 is in use. The back member 44 is the surface opposite to the front member 43. In this embodiment, the front member 43 and the back member 44 are formed by folding a continuous fibrous material and sewing their edges together to create a bag shape with a space between the front member 43 and the back member 44. However, the second bag 4 may be formed in a variety of ways.

[0024] Figure 5 is a schematic perspective view of the urethane chip 6. As shown in Figure 5, the urethane chip 6 is formed from a foam, preferably from a flexible polyurethane foam. The urethane chip 6 in this embodiment is formed from a foam with a hardness of 80N or more, preferably from a foam with a hardness of 100N or more, according to the test method shown in JIS K6401. Furthermore, the density of the foam of the urethane chip 6 is 20 kg / m³. 3 The above is preferable, preferably 30 kg / m 3 That concludes the explanation. However, urethane chips 6 can be formed from a variety of foam materials with different hardnesses and densities. Urethane chips 6 are porous materials that contain a cellular structure with a hollow resin skeleton inside. As a result, urethane chips 6 can be breathable through the cellular structure even when wet. Therefore, urethane chips 6 have good breathability and can be kept clean.

[0025] Furthermore, the urethane chip 6 has at least two faces that are substantially the same distance from each other. The urethane chip 6 is formed such that at least a pair of opposing faces are substantially the same distance from each other regardless of their location. That is, the urethane chip 6 is a hexahedron formed by including six faces, including a pair of faces that are parallel to each other, preferably a parallelepiped, more preferably a substantially rectangular parallelepiped, and may even be a substantially cube.

[0026] Furthermore, the urethane chip 6 may, for example, be a roughly rectangular prism with sides of 2 mm to 12 mm, or, for example, a roughly rectangular prism with dimensions of 2 mm to 8 mm in height, 2 mm to 8 mm in width, and 3 mm to 12 mm in length. In addition, the urethane chip 6 may be a roughly rectangular prism with dimensions of 1 mm to 10 mm in height, 1 mm to 10 mm in width, and 2 mm to 20 mm in length.

[0027] As shown in Figure 5, in this embodiment, the urethane chip 6 has sides a and b of approximately equal length, and side c of approximately equal length. The urethane chip 6 is formed with sides a and b of approximately 4 mm and side c of approximately 6 mm. In other words, the urethane chip 6 in this embodiment is a prism with a base formed by sides a and b of approximately square. As a result, when the user M's head is placed on the pillow 1, the urethane chip 6 can stably support the user M's head with appropriate resilience without collapsing.

[0028] Next, the manufacturing method for the urethane chip 6 will be described. The first direction is the direction along the first side a of the urethane chip 6 shown in Figure 5. The second direction is the direction along the second side b of the urethane chip 6. The third direction is the direction along the third side c of the urethane chip 6. In other words, the first, second, and third directions intersect each other.

[0029] First, a urethane sheet of a predetermined thickness is prepared by horizontally cutting a block of urethane foam, extending in the first and second directions. The thickness of the urethane sheet, which is the size along the third direction, is the same as the third side c. Next, the urethane sheet is repeatedly cut at intervals in the second direction equal to the length of the second side b. As a result, the urethane sheet is formed into numerous rod-like shapes that extend along the first direction of a rectangular cross-section. That is, the second side b and the third side c are formed on these rod-like objects.

[0030] Finally, the rod-shaped urethane sheet is repeatedly cut at intervals equal to the length of the first side a in the first direction. This forms urethane chips 6 of the same length as the first side a from the rod-shaped urethane sheet. This creates prism-shaped urethane chips 6 with a cross-sectional area of ​​the length of the first side a and the second side b, and a length equal to the length of the third side c.

[0031] In this embodiment, the urethane sheet extending in the first and second directions was cut, and then cuts were made in the second and first directions; however, the disclosure is not limited thereto. That is, the urethane chips 6 can be formed to a certain size by regularly cutting from a block of urethane foam through a urethane sheet.

[0032] For example, urethane chips 6 may be formed by repeatedly cutting a urethane sheet extending in the third and second directions along the third and second directions. Alternatively, urethane chips 6 may be formed by repeatedly cutting a urethane sheet extending in the third and first directions along the third and first directions.

[0033] As described above, the urethane chips 6 are formed by cutting a pre-formed urethane sheet having a generally homogeneous porous shape. As a result, the urethane chips 6 themselves also have a generally homogeneous porous shape. Furthermore, the urethane chips 6 can be easily and efficiently produced in large quantities with uniform shapes, minimizing variations in their form. Therefore, variations in breathability can be suppressed among multiple urethane chips 6. As a result, the urethane chips 6 have good breathability and can be kept clean.

[0034] In this embodiment, the urethane chips 6 are formed by simultaneously cutting a urethane sheet along a first direction and a second direction. However, the urethane chips 6 may be formed by a variety of other methods.

[0035] As shown in Figures 3 and 4, multiple urethane chips 6 are filled into the first bag 2 and the second bag 4. The amount of urethane chips 6 is adjusted so that the first bag 2 and the second bag 4 reach the desired hardness. As a result, the first bag 2 and the second bag 4 are filled with urethane chips 6 of roughly the same shape. Therefore, the inside of the first bag 2 and the second bag 4 is evenly filled with multiple urethane chips 6 of roughly the same shape without uneven distribution. This prevents unevenness in air permeability while achieving the desired hardness in the first bag 2 and the second bag 4. As a result, the air permeability of the first bag 2 and the second bag 4 can be improved.

[0036] In this embodiment, multiple urethane chips 6 are filled into the first bag 2 and the second bag 4 in a weight of approximately 300g to 600g. Furthermore, the multiple urethane chips 6 are adjusted and filled into the first bag 2 and the second bag 4 so that they have approximately the same hardness. However, the multiple urethane chips 6 may be adjusted and filled into the first bag 2 and the second bag 4 so that they have different hardnesses.

[0037] Cover 8 is made of fibers including cotton and / or polyester. In this embodiment, cover 8 is formed of 100% cotton fibers. Alternatively, cover 8 may be formed of a blend of cotton and polyester fibers. In addition, cover 8 may be formed using a variety of fibers.

[0038] The cover 8 has a first storage section 81 and a second storage section 82. The first storage section 81 is formed in approximately the same shape as the first bag 2 and houses the first bag 2. The first storage section 81, like the first bag 2, includes a front member 83 and a back member 84. The front member 83 covers the front member 23 of the first bag 2 when the first bag 2 is stored in the first storage section 81. The back member 84 covers the back member 24 of the first bag 2 when the first bag 2 is stored in the first storage section 81.

[0039] Furthermore, the first storage section 81 may include a first opening / closing section (not shown). The first opening / closing section allows the first storage section 81 to be switched between an open state in which the first bag 2 can be inserted and removed, and a closed state in which the first bag 2 is stored. In this embodiment, the first opening / closing section is a fastener provided at one end of the width direction W of the first storage section 81. Alternatively, the first opening / closing section may be a folded-over section that extends from one of the front member 83 and the back member 84 and is folded back and stored on the other. However, the first opening / closing section may be formed by applying various opening and closing means.

[0040] The second storage section 82 is formed to be approximately the same shape as the second bag 4 and houses the second bag 4. The second storage section 82 includes a front member 86 and a back member 87, similar to the first bag 2 and the first storage section 81. The front member 86 covers the front member 43 of the second bag 4 when the second bag 4 is stored in the second storage section 82. The back member 87 covers the back member 44 of the second bag 4 when the second bag 4 is stored in the second storage section 82.

[0041] The second storage section 82 is integrally provided with the front member 83 of the first storage section 81. In this embodiment, the back member 87 of the second storage section 82 is a part of the front member 83 of the first storage section 81. That is, the second storage section 82 is provided between a part of the front member 83 of the first storage section 81 and the front member 88 of the second storage section 82.

[0042] The second storage section 82 may further include a second opening / closing section (not shown). The second opening / closing section allows the second storage section 82 to be switched between an open state in which the second bag 4 can be inserted and removed, and a closed state in which the second bag 4 is stored. In this embodiment, the second opening / closing section is provided as a folded section that folds one end of the width direction W of the outer member 88 into the interior of the second storage section 82. However, the second opening / closing section may be provided as a fastener, similar to the first opening / closing section, or it may be formed by applying various opening and closing means.

[0043] The second storage section 82 is provided integrally with the first storage section 81 so as to overlap with at least one of the multiple slits 25 of the first bag 2 in Figure 2 when viewed from above. That is, when the first bag 2 and the second bag 4 are stored in the first storage section 81 and the second storage section 82 respectively, the second bag 4 is positioned to overlap with at least one of the multiple slits 25. The second bag 4 only needs to be positioned to overlap with at least the second slit 27. This allows the second bag 4 to be positioned to conform to the curve of the nape of the user's neck when the user's head rests on the pillow 1. As a result, the user can use the pillow 1 in a stable state without having to adjust the position of the pillow 1 and their head.

[0044] In this embodiment, the length H in the vertical direction of the second storage section 82 is formed to be the same as / larger than the distance L between the first slit 26 and the second slit 27. As a result, when the second bag 4 is stored in the second storage section 82, it is positioned to straddle the space between the first slit 26 and the second slit 27. This allows the second bag 4 to be positioned to conform to the curve from the back of the user's head to the nape of their neck when the user's head M is placed on the pillow 1.

[0045] Furthermore, in this embodiment, the length of the second storage section 82 is formed to be smaller than the length of the first slit 26 in the width direction W. Furthermore, the length of the second storage section 82 in the width direction W is formed to be the same as / larger than the length of the second slit 27 in the width direction W. This prevents the position of the second bag 4 from being displaced in the width direction W when the first bag 2 and the second bag 4 are stored in the first storage section 81 and the second storage section 82, respectively. Furthermore, it prevents the multiple urethane chips 6 filled in the second bag 4 from being unevenly distributed.

[0046] As shown in Figure 3, in the cross-section AA, which is near the center of the width W of the pillow 1, the first bag 2 is divided into three spaces: a first space 28, a second space 29, and a third space 30, separated by a first slit 26 and a second slit 27. Multiple urethane chips 6 are filled into each of the first space 28, second space 29, and third space 30 to adjust to the desired hardness. Furthermore, the second bag 4 is positioned above the first bag 2, overlapping the first slit 26 and the second slit 27. The second bag 4 is filled with multiple urethane chips 6, similar to the first bag 2, and adjusted to approximately the same hardness as the first bag 2. The cover 8 has a first storage section 81 that covers the entire first bag 2, and a second storage section 82 that covers the entire second bag 4.

[0047] As shown in Figure 4, at the BB cross section, which is the end portion W in the width direction of the pillow 1, multiple urethane chips 6 are filled into a space D enclosed by the front member 23 and back member 24 of the first bag body 2. The cover 8 has a first storage section 81 that covers the entire first bag body 2.

[0048] As explained above, near the center of the vertical direction H, the second bag 4 is placed on top of the first bag 2, resulting in a greater thickness T than elsewhere. This allows the second bag 4 to be positioned to conform to the curve from the back of the head to the nape of the neck when the user M's head is placed on the pillow 1. Therefore, in the vertical direction H, the user M can use the pillow 1 in a stable position without having to adjust the position of the pillow 1 and their head.

[0049] Furthermore, near the center of the width W of the pillow 1, the thickness T is smaller than elsewhere due to the first slit 26 and second slit 27 of the first bag 2. As a result, when the user M's head is placed on the pillow 1, the head can be stably positioned near the center of the width W. Therefore, in the width W, the user M can use the pillow 1 in a stable state without having to adjust the position of the pillow 1 and their head.

[0050] As explained above, this disclosure makes it possible to provide a novel pillow. [Explanation of symbols]
