Description

  The present invention relates to a pillow, and more particularly to a pillow on which a sleeping human head is placed.

  It has been considered that a large number of granular objects are built in such a pillow to improve the touch of the head and to obtain good sleep. Examples of such granular materials include a perfect sphere, an elliptic sphere, a cylinder, and a pipe.

  However, when multiple types of such granular materials are prepared and incorporated in the pillow, different types of granular materials enter each other when used or when the pillow is washed, etc. There was a case where the volume of the whole granular material was reduced by entering the other granular material.

  The present invention has been made in order to solve the above-described problems, and the object of the present invention is to prevent one granular material from entering the other granular material when incorporating the granular material in the pillow. It is an object of the present invention to provide a pillow that can be used comfortably for a long time without reducing the volume of the entire granular material even if the pillow is used for a long time or is washed.

  The first invention of the present invention includes a large number of cylindrical first granular materials having insertion holes, which are housed in outer covers constituting the outer surfaces of the front side and the back side of the pillow, and the front side and the back side of the pillow. A cylindrical shape, an elliptical spherical shape, or a cylindrical shape having an insertion hole smaller than the thickness of the first granular material, and having a size larger than the insertion hole of the first granular material. And a large number of second spherical particles having a perfect spherical shape.

  The second aspect of the present invention includes a plurality of separation layers separated by a separation body built in the pillow with respect to a direction in which the human head is placed, that is, a vertical direction inside the pillow, and the plurality of separation layers. Among the separation layers, the separation layers that are in contact with the human head are joined to each other with respect to a direction perpendicular to a direction in which the human head is placed, that is, a horizontal direction. A plurality of divided bodies divided by the above, a third granular material incorporated in the plurality of divided bodies, and a third granular material incorporated in a separation layer below the separation layer that constitutes the divided body. Soft fourth granular material.

  According to the first invention, the first granular material does not enter the insertion hole of the second granular material, and the second granular material does not enter the insertion hole of the first granular material. Therefore, even if it is used for a long time or washing a pillow, it can be used comfortably for a long time without reducing the volume of the entire granular material.

  According to the second invention, since the third granular material and the fourth granular material are incorporated in separate separation layers, one granular material does not enter the other granular material. In particular, the soft fourth granular material does not enter the hard third granular material. Alternatively, the third granular material is not a simple separation layer, but is contained in a divided body obtained by further dividing the separation layer, so that the third granular material is not unevenly distributed due to the weight of the head. In particular, since the third granular material is hard, it is more likely to be unevenly distributed, but such uneven distribution can be prevented.

(1) Structure of Pillow Body 1 FIG. 1, FIG. 2 and FIG. 3 show the front surface (front surface), back surface (back surface) and cross section of the pillow. A pillow body 1 on which a sleeping human head is placed has a rectangular outer cloth (outer jacket) 2 and back cloth (outer jacket) 3 sewn at the periphery.

  A rectangular separation cloth 4 is sandwiched between the front cloth 2 and the back cloth 3, and the separation cloth 4 is sewn together with the front cloth 2 and the back cloth 3 at the periphery. By this separation cloth 4, the front side and the back side in the pillow main body 1 are separated from each other, and a multilayer structure including a plurality of separation layers of the front separation layer 5 and the back separation layer 6 is formed.

  The front cloth 2 and the separation cloth 4 are stitched together by a plurality of, for example, four front stitching lines (joining lines) 7. The separation layer 5 between the front cloth 2 and the separation cloth 4 in the pillow main body 1 is divided by the four front stitching lines 7..., 7a to form five rows of elongated divided sac 8. . The divided sacs 8 are shielded from each other by the four front stitching lines 7.

  The width of the end divided sac 8a formed by the end surface stitching line 7a, which is near the human neck of the end of the five rows of divided sac 8 ... is slightly thicker than the width of the other divided sac 8 .... The end division sac 8a is further divided into three by two end stitching lines (joining lines) 9. The three end division sac 8a are shielded from each other by the two end stitching lines 9.

  In the back separating layer 6 between the separating cloth (separating body) 4 and the backing cloth (cover) 3, another rectangular back separating cloth (separating body) 10 is sandwiched, and this back separation is performed. The cloth 10 is sewn on the front cloth 2, the back cloth 3, and the separation cloth 4 at the periphery of three sides. The peripheral edge of the remaining one side of the back separating cloth 10 is stitched (joined) to the end surface stitching line 7a of the end division sac 8a.

  Between the separated cloth 4 on the back separating cloth 10 is an upper back separating layer 6a, and between the separated cloth 4 under the back separating layer 10 is a lower back separating layer 6b. . The lower back separation layer 6b is also surrounded by the separation cloth 4 in the lower part of the end division sac 8a.

  The backing cloth 3 is quilted by overlapping two or more cloths such as non-woven fabrics and stitching them at a number of oblique back stitching lines 11. On the other hand, as described above, the front cloth 2 is formed with four front stitching lines 7. Thereby, the surface design and surface shape of the front and back sides of the pillow body 1 are different, the front and back of the pillow body 1 are clearly distinguished, and the front and back of the pillow body 1 are not mistaken.

(2) Built-in Granular Material FIG. 4 shows various granular materials housed / built in the pillow body 1. This granular material is composed of a hard cylindrical granular material 21, a soft cylindrical granular material 22, and a spherical granular material 23.

  The hard cylindrical granular material (polycut tube) 21 is, for example, 4 to 15 mm in length, desirably 6 to 10 mm, 3 to 10 mm in outer diameter, desirably 4 to 5 mm, and thickness 0.01 to 1 mm, desirably 0. .05 to 0.1 mm, and the material is made of synthetic resin (plastic) such as polyethylene or polypropylene, and is relatively hard but flexible.

  The soft cylindrical granular material (polycut tube) 22 is, for example, 4 to 15 mm in length, desirably 6 to 10 mm, 3 to 10 mm in outer diameter, desirably 4 to 5 mm, and 0.01 to 1 mm in thickness, desirably It is 0.05 to 0.1 mm, and the material is made of synthetic resin (plastic) such as polyethylene, polypropylene, acrylic, etc., is relatively soft and flexible, and is softer than the hard cylindrical granular material 21.

  The spherical granular material 23 has, for example, an outer diameter of 3 to 20 mm, preferably 5 to 10 mm, a thickness of 0.01 to 1 mm, preferably 0.05 to 0.1 mm, and is made of polyethylene, polypropylene, acrylic, etc. It is made of synthetic resin (plastic) and is relatively hard but flexible. The hardness may be harder or softer than the hard cylindrical particulates 21... And / or the soft cylindrical particulates 22.

  Since the hard cylindrical particles 21... And the soft cylindrical particles 22 are cylindrical, insertion holes 24 and 25 are formed, and a pair of insertion holes 26 and 26 are also formed in the spherical particles 23. Yes. The size of the insertion hole 26 of the spherical granular material 23 is 20% to 50% of the outer diameter of the spherical granular material 23, and is 0.6 to 10 mm, preferably 1 to 5 mm. Also, the sizes of the insertion holes 24 and 25 of the hard cylindrical granular materials 21 and the soft cylindrical granular materials 22 are 2 to 9.99 mm, preferably 3 to 4.99 mm.

  The hard cylindrical granular materials 21 and the spherical granular materials 23 are accommodated / built in the divided sac (divided body) 8 (surface separation layer 5), and the soft cylindrical granular materials 22 and the spherical granular materials 23 are It is stored / built in the upper / back separation layer 6a (back separation layer 6).

  Therefore, since the hard cylindrical granular material 21 ... and the soft cylindrical granular material 22 ... are not stored in the same location of the pillow body 1, the hard cylindrical granular material 21 ... enters the insertion hole 25 of the soft cylindrical granular material 22 .... On the contrary, the soft cylindrical particles 22 do not enter the insertion holes 24 of the hard cylindrical particles 21. Therefore, even if it is used for a long time or the pillow body 1 is washed, the volume of the granular materials 21, 22, and 23 as a whole is not reduced and can be used comfortably for a long time.

  The size of the insertion hole 26 of the spherical granular material 23 is smaller than the outer diameter / size / thickness of the hard cylindrical granular material 21 and the soft cylindrical granular material 22 and the outer diameter of the spherical granular material 23. The size is selected to be larger than the size of the insertion holes 24 and 25 of the hard cylindrical granular material 21 and the soft cylindrical granular material 22. Therefore, the hard cylindrical particles 21 and the soft cylindrical particles 22 do not enter the insertion holes 26 of the spherical particles 23. Conversely, the spherical particles 23. And the soft cylindrical granular material 22 ... does not enter the insertion holes 24, 25. Therefore, even if it is used for a long time or the pillow body 1 is washed, the volume of the granular materials 21, 22, and 23 as a whole is not reduced and can be used comfortably for a long time.

  In addition, the granular material accommodated in the said division | segmentation bag (division body) 8 (front separation layer 5) and the upper back separation layer 6a (back separation layer 6) is good also as only the spherical granular material 23 .... In that case, the particulate matter is less likely to enter. However, since the hard cylindrical particles 21 and the soft cylindrical particles 22 are cylindrical, they are excellent in air permeability / heat dissipation / drying properties. Therefore, it is good to mix both. The mixing ratio of the two is 10% to 90%: 90% to 10%, preferably 50%: 50% by weight.

  In the above-described end-divided sac (divided body) 8a (surface separation layer 5), soft cotton-like or cloth-like filled cotton (fiber body) 27 having flexibility is stored / built in. The filled cotton 27 is softer than the soft cylindrical particles 22. Therefore, since the filling cotton 27 hits the end-divided sac (divided body) 8a (surface separation layer 5) to which the scruff below the head hits, the scruff does not become painful.

  The lower back separation layer 6b (back separation layer 6) is hollow, but may be filled with filled cotton (fiber body) 27. As a result, the hardness / softness can be gradually changed over the separation layers 5, 6a, 6b of the pillow body 1, and the weight / pressure of the head can be comfortably distributed throughout the pillow body 1 without concentrating on one point. Can be made.

  And since the hardest hard cylindrical granular material 21 ... hits the location nearest to the head, a massage effect can be exhibited. Further, when the pillow body 1 is turned over when it is cold, the softest filled cotton 27 is applied to the portion closest to the head, so that the entire head can be wrapped and kept warm. If the entire pillow 1 is returned to its original position when it is hot, the hard cylindrical granular material 21 with high air permeability hits the portion closest to the head, so that it can ventilate / heat radiate / dry and the hard cylindrical granular material 21 ... Is hard and difficult to deform, so this heat dissipation can be maintained.

  Moreover, the hardness of the filling cotton 27 of this end division sac (divided body) 8a may be made harder than that of the filling cotton 27 of the lower back separation layer 6b. Thereby, it is possible to comfortably disperse the weight / pressure of the neck throughout the pillow body 1 without concentrating on one point. Of course, it may be soft. Thereby, a neck can be warmed more efficiently. Moreover, the same hardness may be sufficient as mentioned above.

  Part or all of the hard cylindrical granular materials 21..., The soft cylindrical granular materials 22. As a result, even if they are deformed by the weight of the head using the pillow body 1, if they are released from the weight of the head, they will return to their original shapes and will be antibacterial / deodorizing / Heating action / blood circulation promoting action such as decomposition action, far-infrared ray generation action, etc. do not decrease. Further, for the same reason, the filling cotton 27, the front cloth 2, the back cloth 3, the separation cloth 4, and the back separation cloth 10 may similarly have a shape memory action.

  Anti-bacterial action such as photocatalytic action / deodorizing action / insect-proofing action / decomposition action on a part or all of the surface of the hard cylindrical granular material 21..., Soft cylindrical granular material 22. A part or all of the filled cotton 27, the front cloth 2, the back cloth 3, the separation cloth 4 and / or the back separation cloth 10 has a heating action / blood circulation promoting action such as a far infrared ray generating action.

  This makes it possible to prevent the occurrence of dirt / bad odor due to perspiration due to the warming action / blood circulation promotion by the photocatalytic action, while heating the head / neck with far infrared rays. Further, far infrared rays are a kind of light, and the photocatalytic action can be further exhibited by far infrared rays.

  In addition, some or all of the hard cylindrical particles 21..., The soft cylindrical particles 22... And / or the spherical particles 23 may have a heating effect / blood circulation promoting effect such as a far infrared ray generating effect, Part or all of the filling cotton 27, the front cloth 2, the back cloth 3, the separation cloth 4 and / or the back separation cloth 10 may have antibacterial action / deodorant action / insect repellent action / decomposition action such as photocatalytic action. .

  Further, it is desirable that only a part or all of the spherical particles 23 have an antibacterial action / odor prevention action / insect prevention action / decomposition action such as a photocatalytic action. There is a slight possibility that the hard cylindrical particles 21 and / or the soft cylindrical particles 22 may be crushed by the pressure / gravity of the head and enter the spherical particles 23. On the contrary, since there is no possibility that the spherical granular material 23 ... enters the hard cylindrical granular material 21 ... and / or the soft cylindrical granular material 22, ..., the photocatalytic action of the granular materials 21, 22, 23 as a whole decreases. This is because it never happens.

  In some cases, apatite-processed silica gel is mixed with the hard cylindrical granular materials 21, the soft cylindrical granular materials 22, and the spherical granular materials 23. Thereby, the said drying effect | action can be improved more. In the drawing, it appears that there are gaps in the divided sac (divided body) 8 and the lower back separation layer 6b in addition to the hard cylindrical granular material 21..., The soft cylindrical granular material 22. This is to make it easy to see the drawing, and in reality, the granular materials 21... 22.

  Examples of materials that exhibit antibacterial / deodorant / insect control / decomposition such as photocatalysis include titanium dioxide, CdS, CdSe, WO3, Fe2O3, SrTiO3, KNbO, shine-up (fiber, cloth, cotton), Zeolite, wool zeolite, Yanglon processed cloth / cotton, etc. are selected as materials from which dismel (a product of Toyobo Co., Ltd.), epicomodo, etc. exerts warming / blood circulation promoting effects such as far-infrared ray generation.

(3) Usage of Pillow Main Body 1 FIGS. 5 and 6 show cross sections of the pillow main body 1 in use. The length / width of the separation cloth 4 in each of the divided sac (divided body) 8 and the end divided sac (divided body) 8 a is shorter / narrower than the length / width of the front cloth 2. Therefore, each divided sac (divided body) 8 and end divided sac (divided body) 8a containing / accommodating the hard cylindrical granular material 21... Or filled cotton 27 swells upward and a human head is placed. A gap 28 is formed between each divided sac (divided body) 8 and end divided sac (divided body) 8a. Accordingly, it is possible to further improve the air permeability / heat dissipation / drying property of the above-described hard cylindrical particles 21... And soft cylindrical particles 22. Similarly, the upper back separation layer 6a or the lower back separation layer 6b may have a structure that swells upward or downward (when turned over).

  Further, as shown in FIG. 5, since the gap 28 is not formed in the left-right direction of the head, the head does not feel uncomfortable. This is because, while sleeping, the head moves left and right and does not move much up and down, so if there is a gap 28 in the left and right direction, when the head moves, a sense of incongruity occurs. On the other hand, as shown in FIG. 4, even if there is a gap 28 in the vertical direction, the head while sleeping does not move much up and down, so there is not much discomfort.

  In addition, each division sac (division body) 8 and end division sac (division body) 8a may be divided in the left-right direction instead of being divided in the vertical direction, or may be divided in the vertical direction and the left-right direction. It may be divided in an oblique direction. Each of the upper back separation layer 6a and the lower back separation layer 6b may be divided into a plurality of pieces, such as the divided sac 8 and the end divided sac 8a.

  Since the hard cylindrical granular materials 21 are dispersed and housed / built in each divided sac (divided body) 8, the hard cylindrical granular materials 21 are not biased by the pressure / weight of the head. Moreover, since the filling cotton 27 is also housed / built in the end divided sac (divided body) 8a divided into three parts, the filling cotton 2 is not unevenly distributed due to the pressure / weight of the neck. The divided sac (divided body) 8 and the end divided sac (divided body) 8a may not be divided and may be partly or wholly connected together.

  Even if such a pillow body 1 is washed, it does not lose its shape, and the hard cylindrical particles 21, the soft cylindrical particles 22, and the spherical particles 23 do not enter each other. Also, it can withstand washing by round washing, and even when dried at 70 to 90 degrees, it does not lose its shape, and the hard cylindrical granular material 21... The soft cylindrical granular material 22. There is no.

  The backing cloth 3 is quilted by overlapping several cloths and stitching them with a large number of oblique back stitching lines 11. On the other hand, as described above, the front cloth 2 is formed with four front stitching lines 7. Thereby, the surface design and surface shape of the front and back sides of the pillow body 1 are different, the front and back of the pillow body 1 are clearly distinguished, and the front and back of the pillow body 1 are not mistaken.

  The difference between the front stitching lines 7 ..., 7a on the front side of the pillow body 1 and the back stitching line 11 on the back side can be seen by hand, the tactile feel is different, and the front and back are clearly distinguished. , Not to mistake the front and back. Depending on the case, the front and back surface patterns or / and surface colors of the pillow body 1 are different. Thereby, the front and back of the pillow main body 1 are clearly distinguished, and the front and back are not mistaken.

(4) Other Embodiments The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the front cloth (outer cover) 2, the back cloth (outer cover) 3, the separation cloth (separator) 4, or the back separation cloth (separator) 10 may be a cloth having good air permeability or a net shape. Thereby, the heat from the human head placed on the pillow body 1 can be efficiently radiated.

  Further, the separation cloth (separator) 4 or the back separation cloth (separator) 10, and the inner side of the front cloth (outer jacket) 2 and the inner side of the back cloth (outer jacket) 3 may reflect light such as metal fibers. High cloth may be used. Thereby, when the hard cylindrical granular materials 21..., The soft cylindrical granular materials 22... Or the spherical granular materials 23 have a photocatalytic function, this function can be improved by light reflection. Further, the far infrared rays can be reflected to improve the heating effect / blood circulation promoting effect by the far infrared rays.

  Further, the hard cylindrical particles 21 and the soft cylindrical particles 22 have the same shape and the same size, but may have different shapes and sizes, and one may be longer / thicker / thick / larger than the other. If the same material and the same thickness are used, the larger the material, the softer the hardness. Therefore, the larger one can be the soft cylindrical granular material 22.

  Further, the hard cylindrical granular materials 21 and the soft cylindrical granular materials 22 may be elliptical or perfectly spherical in addition to the cylindrical shape. Further, the spherical granular material 23 may be not only a perfect sphere but also a cylinder or an ellipsoid. A plurality of insertion holes 24 and 25 may be formed on the side surfaces of the hard cylindrical granular material 21 and the soft cylindrical granular material 22, and a large number of insertion holes 26 may be formed on the surface of the spherical granular material 23. And only one may be formed. Part or all of the insertion holes 24, 25, or 26 of the hard cylindrical granular material 21 ..., the soft cylindrical granular material 22 ... or the spherical granular material 23 ... may be omitted.

  Furthermore, the filling cotton 27 in the end division sac (division body) 8a may be omitted. The lower back separation layer 6b or the end divided sac 8a may contain / store soft cylindrical particles 22 instead of the filled cotton 27, and the upper back separation layer 6a may contain soft cylindrical particles 22 ... Instead, the filling cotton 27 may be incorporated / stored.

  Further, the peripheral edge of the back separation cloth 10 may all be aligned with the peripheral edges of the front cloth 2, the back cloth 3, and the separation cloth 4, and may be sewn / joined. Conversely, the entire periphery of the back separating cloth 10 may be sewn / joined only to the separating cloth 4 by the front stitching lines 7.

  Still other granular materials may be additionally mixed with the hard cylindrical granular materials 21 or the soft cylindrical granular materials 22 and the spherical granular materials 23. In this case, the other granular material to be added and mixed is usually a perfect sphere or an oval sphere, and the size may be larger or smaller than the spherical granular material 23. However, the shape / size so that the hard cylindrical particles 21... Or the soft cylindrical particles 22... Do not enter, and the shape / size that does not enter the hard cylindrical particles 21. Is done.

  The hardness of the other granular material to be added and mixed is harder when it is embedded / stored in the divided capsule 8 than when it is embedded / stored in the upper back separation layer 6a, but it may be the same hardness. . Further, the hardness / size of the spherical granular material 23 is the same hardness / size as that contained in / accommodated in the upper back separation layer 6a and that contained / stored in the divided sac 8. However, the one contained / stored in the divided sac 8 may be harder / smaller than the one contained / stored in the upper / back separation layer 6a.

  The lower back separation layer 6b may contain / store a softer granular material than the soft cylindrical granular material 22... Or the spherical granular material 23. The number of the front separation layer 5, the upper and lower separation layers 6a (back separation layer 6), and the lower and rear separation layers 6b (back separation layer 6) may be increased, and the pillow body 1 may be formed in multiple layers. Even in this case, the granular material / fiber body accommodated / incorporated / filled in each separation layer gradually becomes softer as it goes downward.

  The upper back separation layer 6a (back separation layer 6) is divided into a plurality of divided bodies, such as the divided sac (divided body) 8 and the end divided sac (divided body) 8a. Similarly, it is divided into a plurality of divided bodies, and similarly, each separation layer may be further divided into a plurality of divided bodies. In this case, as the interior / accommodated granular material / fiber body becomes softer, the number of the divided bodies may decrease or increase.

  As the granular material / fiber body becomes softer, when the number of divided bodies decreases, the softer the granular material / fiber body becomes, the less unevenly distributed, so the number of divided bodies can be changed according to the frequency of uneven distribution. it can. As the granular material / fiber body becomes softer, when the number of divided bodies increases, the softer the granular material / fiber body, the easier it is to deform. Therefore, the number of divided bodies should be changed according to the ease of deformation. Can do.

Thereby, the first granular material does not enter the insertion hole of the second granular material, and the second granular material does not enter the insertion hole of the first granular material. Therefore, even if it is used for a long time or washing a pillow, it can be used comfortably for a long time without reducing the volume of the entire granular material.

[2] The inside of the pillow is separated into a plurality of separation layers by a separator incorporated in the pillow with respect to a direction in which the human head is placed, that is, a vertical direction. The first granular material and the second granular material are built in, and the first granular material and the second granular material are different in size or hardness for each separation layer. Item 2. The pillow according to item 1. As a result, various hardnesses / various tactile sensations to the head can be realized simultaneously.

[3] The inside of the pillow is separated into a plurality of separation layers by a separator incorporated in the pillow with respect to a direction in which the human head is placed, that is, a vertical direction.

  Thereby, since a 3rd granular material and a 4th granular material are incorporated in a separate separation layer, one granular material does not enter into the other granular material. In particular, the soft fourth granular material does not enter the hard third granular material. Alternatively, the third granular material is not a simple separation layer, but is contained in a divided body obtained by further dividing the separation layer, so that the third granular material is not unevenly distributed due to the weight of the head. In particular, since the third granular material is hard, it is likely to be unevenly distributed, but such uneven distribution can be prevented.

[6] The first granular material, the second granular material, the third granular material, the fourth granular material, the outer cover of the pillow, the separated body and / or the fiber body have a photocatalytic function or a far infrared ray generating function.
