Description

  The present invention relates to a pillow cover. More specifically, the present invention relates to a pillow cover capable of protecting a cervical spine while sleeping.

  In recent years, in order to protect the cervical spine, the idea of laying a pillow under the neck and closing the gap with the neck floating from the pillow has been proposed. For example, a sheet of low-resilience urethane foam provided on the back side of the pillow cover to fill the gap between the pillow and the neck (Patent Document 1), a soft heat insulator on the cervical spine, Specifically, a plastic air bag that fills the gap between the pillow and the cervical spine at the position of the cervical spine is provided, and the back of the neck is supported by an insulating air bag and kept warm, improving blood circulation in the neck muscles. In addition, a pillow cover has been proposed that is useful for eliminating stiff shoulders and a good night's sleep (Patent Document 2).

  Furthermore, a pillow used for the purpose of filling the gap between the necks and reducing the burden on the neck has also been proposed (Patent Document 3). This pillow is a thin band-shaped pillow that fills the gap between the bedclothes of the cervical spine in the sleeping state, and is used in a state of being wrapped around the neck using locking means such as a hook-and-loop fastener and a hook. By filling the gap under the neck with a small pillow at bedtime, the burden on the neck is reduced and the airway is secured so that it is possible to sleep well.

  In addition, a shoulder cover with a pillow cover has been proposed that prevents the shoulder from cooling when sleeping in cold weather by using a shoulder pad that fills the gap between the pillow and the shoulder in conjunction with the pillow cover. Reference 4). This shoulder rest is a drum-shaped object with thick ends and a thin center, and is a stick-shaped object filled with an elastic and heat-retaining material, which is somewhat smaller than the thickness of a commonly used pillow. Thus, the gap between the pillow and the shoulder is filled to prevent the shoulder from being cooled, the cold air from entering the futon, or the futon from coming out of the warm air.

  However, both of them maintain the posture of the curved cervical vertebra by supporting the neck in the same way as the pillow that supports the head, so that pressure around the cervical vertebra is likely to occur, and there is a risk of obstructing blood and lymph flow. Is. Airbags, low-resilience urethane foam, supports filled with elastic fillers, etc. seem to be elastic and soft at first glance, but due to their resilience, there is a risk that compression will occur due to close contact with the cervical spine as a neck pillow. is there. For example, even in pillows made of low-resilience urethane foam, the part that supports the head and the part that supports the cervical vertebra are made of the same material. Has become a pressure, and the sense of pressure tends to become stronger due to changes in stiffness due to aging. On the other hand, there are individual differences in human body shape, so the muscle tension is also different. Therefore, if the stiffness and height are specified as in a conventional pillow, there is a person who is compressed on the cervical spine, blood circulation is worsened, and muscles become more tense, preventing natural sleep. come. Cervical spine compression is not sufficient to prevent blood flow and lymph flow around the neck while sleeping, and to reduce the burden on the cervical spine while sleeping, resulting in neck pain and limbs There are complaints that things like numbness, airway maintenance and sleep disorders are not improved sufficiently.

  Therefore, an object of the present invention is to provide a pillow cover that can lightly support a cervical vertebra during sleeping without pressing. More specifically, the present invention promotes the flow of blood and lymph fluid by reducing the burden on the cervical spine during sleep, thereby improving numbness of the limbs resulting from this, neck pain when waking up, and refreshing due to sleep It is an object to provide a pillow cover that can provide a feeling and the like.

  As a result of various experiments conducted by the present inventors in order to achieve such an object, even though the cervical spine is not supported, the cervical spine is burdened, but the support that can be recognized as having some support under the cervical spine is also counterproductive, It came to know that the support to the extent that it is hardly supported is actually preferable. In other words, if it becomes difficult to maintain the cervical lordosis during sleep, the muscles will unconsciously become tense and disturb sleep. On the other hand, muscle tension also occurs when a strong pressure is applied to strengthen the outpost. However, when you touch the cervical vertebrae during sleep, you can support without squeezing the cervical vertebrae while being crushed along the shape of the cervical vertebrae, and if you fill the space with the floor that can be used for the cervical lordosis, The inventors of the present invention have come to know that muscle tension can be achieved.

  The present invention is based on such knowledge, and the pillow cover according to the first aspect of the present invention has a pillow cover part on which the head is placed and a winding core part applied to the cervical vertebra part. The core portion is formed by winding a pillow cover material including a sheet-like air layer, and the center portion is softer than both side portions. Therefore, by rolling the sheet-shaped pillow cover material, it is possible to adjust the height and rigidity of the core to match the user's unique cervical forehead, and the soft part wrapped with the pillow cover material in that state is the cervical spine. When the cervical spine is touched, a light support is formed so as to fill the gap below the cervical vertebra while collapsing along the shape of the cervical vertebra when touching the cervical spine.

  The invention according to claim 2 is the pillow cover according to claim 1, wherein the pillow cover part and the winding core part are made of a single cover material, and both ends of the cover material are folded inward to be double. The center part is formed so as to be thin and softer than both side parts. In this case, the central portion of the winding core portion that contacts the cervical vertebra is supported by both side portions that are doubled by folding, and touches the cervical vertebra in a floating state.

  The invention according to claim 3 is characterized in that, in the pillow cover according to claim 1 or 2, the cover material has at least a surface in contact with the cervical spine as a gauze.

  According to a fourth aspect of the present invention, in the pillow cover according to any one of the first to third aspects, the pillow cover portion on which the head portion of the cover material is placed is attached to the pillow and the core portion. And a band for holding the winding.

  According to a fifth aspect of the present invention, in the pillow cover according to any one of the second to fourth aspects, corners of both side portions formed by folding the cover material are opened.

  According to the pillow cover of claim 1, because it has a winding core portion that can be changed to a height and rigidity suitable for the user's cervical lordosis by winding a pillow cover material including a sheet-like air layer, Without applying extra pressure on the cervical spine, the individual cervical vertebral forehead (depending on individual differences) can be naturally shaped. In other words, a cover material including an air layer is rolled to form a tomographic shape (swirl layer) such as air and cloth, thereby maintaining a certain shape and preventing excessive pressure. In addition, since the central part of the winding core that hits the cervical spine is supported by both sides that are stiffer than that, the central part is crushed along the shape of the cervical vertebra when it touches the cervical vertebra, and the cervical vertebra is compressed. Can be supported lightly. For this reason, muscle tension is released, stiff shoulders and poor blood circulation can be prevented, and quality sleep can be taken. Moreover, when the pillow cover material touches the skin of the cervical vertebra part and gives an appropriate stimulus, the neck slightly extends in the direction in which the airway is opened, so that the airway is secured and breathing becomes easy, so that sleep is quiet. This cervical spine support is also the same when turned sideways. Since the pillow cover part and the core part are integrated, the position of the core part does not shift.

  Furthermore, the pillow cover of the present invention has a pillow cover part integrated with the winding core part that supports the cervical spine, and has the original function as a pillow cover, so sheets and the like can be used with sebum and hair dressing from the head. It can prevent getting dirty. Moreover, because it is a pillow cover wrapped with a sheet-like pillow cover material, it is easy to carry because it can be folded by unwinding the core and is lightweight, so it is limited to use when sleeping on a futon. In some cases, it can be used when sitting on a seat in a car or train. In addition, since the cover material including the air layer is partially rounded, it can be manufactured at low cost.

  Furthermore, according to the pillow cover according to claim 2, both ends of the pillow cover material are folded inward to make a double, thereby forming both thick and stiff side portions and a single central portion that is thinner and softer than the both side portions. Therefore, the width of the thin and soft central portion can be adjusted according to preference by adjusting the width of the folding. In addition, since the central portion of the winding core portion is supported by both side portions that are doubled by folding, the portion that contacts the cervical vertebra is in a floating state, and when the cervical vertebra is touched, the cervical vertebra is not compressed.

  Furthermore, according to the pillow cover according to claim 3, since the part that directly touches the skin is a gauze fabric, the stimulation to the skin is comfortable and the sweat absorption is excellent, so that the hypnotic effect and the sleep effect can be further improved. I can expect.

  Furthermore, according to the pillow cover of claim 4, it is possible to attach the pillow cover part to a pillow or other non-wearing object such as a headrest of a seat using a band and to keep the height of the winding core part constant. It can be kept, so even if you use the pillow cover on the pillow and put the core on the end of the pillow, it will not fall off the pillow, and you can sit down with the pillow cover attached to the headrest part of the seat Even when used in a posture, the winding core is not unwound and the winding core can be applied to the cervical vertebra.

  Furthermore, according to the pillow cover of the fifth aspect, since the corners of both side portions where the pillow cover material is folded back are opened, it is hygienic without washing dust and other dust collecting.

  Hereinafter, the configuration of the present invention will be described in detail based on embodiments shown in the drawings.

  1 and 2 show an embodiment of the pillow cover of the present invention. This pillow cover is composed of a pillow cover material (hereinafter abbreviated as a cover material) 7 including one sheet-like air layer, and includes a flat pillow cover portion 1 on which a head is placed, and a cervical vertebra portion. And a winding core 2 that supports the cervical spine. In the case of this embodiment, the winding core part 2 is formed by winding a part of the cover material 7, and the pillow cover part 1 is composed of the cover material 7 remaining without being wound. More specifically, the pillow cover according to the present embodiment includes both sides 6 in which both ends of a flat cover material 7 having a substantially rectangular shape are folded inward to double the cover material 7 and a single layer therebetween. 2 having a central portion 5 as shown in FIG. 2 and further winding up from one end of the cover material 7 to form a winding core portion 2 as shown in FIG. The cover part 1 is formed. The winding core portion 2 is formed by folding both sides of the cover material inward to make a double, thick and hard both side portions 6 and a single central portion 5 that is thinner and softer than the both side portions 6. The central portion 5 is softer than the side portions 6, and the width of the thin and soft central portion 5 can be adjusted as desired by adjusting the folding width.

  In addition, in order to prevent the wound core part 2 from being unwound or falling from the pillow near the boundary between the pillow cover part 1 and the core part 2 as an area assumed to be used as an original pillow cover, A holding band 9 is provided. The band 9 is, for example, a rubber band or a non-stretchable string, and can be fixed by hooking the winding core portion 2 to the band 9 by arranging the band 9 at an angle with respect to the fabric and sewing both ends of the band 9 to the cover material 7. I am doing so.

  Further, a holding band 4 is also provided at the end of the pillow cover portion 1. The band 4 is, for example, a rubber band or a non-stretchable string. The band 4 is arranged obliquely with respect to the cover material 7 and both ends thereof are sewn to the fabric. The cover 1 can be fixed to the pillow.

  As the cover material 7, for example, the core 2 can maintain at least a columnar shape without applying an external load, and the cervical vertebra can follow the shape of the cervical vertebra without applying excessive pressure to the cervical vertebra when it is on It must be capable of exhibiting a degree of elasticity that can be crushed, and preferably exhibits a certain degree of elasticity and is gentle to the skin and rich in hygroscopicity. As the cover material 7 in the present embodiment, quilting in which a core material is inserted between the outer material 12 and the lining material 10 and sewed is used. As such quilting, it is generally preferable to use a commercially available product such as a towel for infants or a skin cover. Of course, when a material having a certain degree of elasticity and thickness is used for the outer material 12, for example, when a thick towel or a blanket is used, the gauze material or the like is used for the material such as the towel without using the core material 11. The lining 10 may be sewn directly. Further, although not particularly limited, a gauze fabric is preferable for the portion that directly touches the neck (the lining 10 in this embodiment). Further, it is preferably a woven fabric or fabric having a high hygroscopic property and water absorbing property such as a towel fabric as a whole, and a pile fabric (pile weave) or a raised fabric is preferably used as the outer fabric 12 that directly touches the head. By using a material including an air layer, such as quilting, and further winding the material, the torsional (spiral layer) winding core portion 2 of air and cloth is formed to a certain extent. It will be something that is not overstressed. The height and stiffness of the winding core 2 can be adjusted by changing the number of windings or changing the density of the winding, but the height in the state of being fixed over the band 9 is approximately the same as that of the pillow. It is preferable to make the height somewhat lower than that.

  Here, examples of the core material including an air layer that gives the cover material 7 a certain degree of elasticity include cotton, cotton, polyester cotton, rayon cotton, feathers, wool, panya, urethane foam, etc. Use of cotton, polyester cotton, cotton, rayon cotton, feathers, wool, etc. It is desirable that this batting should be hard enough to feel almost no reaction force when pressed with a fingertip. For example, the preferred thickness differs depending on the material, but when using a cotton core such as polyester cotton, the thickness is 1 to 4 mm (quilting). It is preferable to use about 5 to 7 mm as a whole. Also, when using a sponge material as the core material, if it is molded in advance so that the thickness is different between the central part and both sides, the softness can be made different between the central part and both sides without folding. it can.

  It is preferable that the corner portions 8 of the side portions 6 formed by folding the cover material 7 are opened without being sewn on the front surface. For example, the edges of the folded back side portions 6 of the cover material 7 and the lower cover material 7 portions are connected by hooks 13 or the like, or sewn at one point, so that the side portions 6 of the folded back and bag shape are formed. Both corners 8 in the longitudinal direction (winding direction) are provided so as to be open. In this case, even if washing dust or the like enters the double side portions 6 that are doubled by folding the cover material 7, it can be easily removed, and it becomes hygienic. Since it can be made into one cloth, it becomes easy to wash. Here, when the folded cover material 7 is fastened with a hook 13 or the like, it is easier to wash if the hook 13 is removed and the folded portion is widened to make one quilting place during washing. It becomes. In the present embodiment, the cover material 7 has a shape in which two corners are cut off obliquely, but is not particularly limited to this, and the four corners may be right-angled corners, The four corners may be cut off obliquely. The shape of the four corners of the cover material 7 is merely a design and does not change greatly in terms of functionality.

  The edge of the cover material 7 made of a quilting material is often edged with a soft cloth, but it is not preferable that the edge is sewn entirely in a folded state. In order to maintain the softness of the winding core 2 of the cover, it is preferable that the edge of the folded cover material 7 is fastened at several points by sewing 14 or hooks. If there are many places to be sewn, the cover material 7 will be stiff and soft, and in order to avoid compression of the cervical vertebra at the winding core 2, it is preferable to sew several points so that the folding does not shift. .

  As shown in FIGS. 4 and 6, the winding core portion 2 is wound in a spiral layer like an annual ring while the cover material 7 including an air layer forms a gap corresponding to the winding method at both side portions 6. However, in the central portion 5 that touches the cervical vertebra, a space having a thickness equivalent to that of one cover material is formed every other sheet. For this reason, the central portion 5 is soft, and the both ends 6 are somewhat rigid. Moreover, the softness of the central portion 5 as well as the whole can be adjusted in accordance with the winding density and the tightening degree.

  According to the pillow cover configured as described above, the pillow cover portion 1 is placed on the pillow 13 and the corner band 4 is fixed on the pillow, and the winding core portion 2 is rolled up while folding the opposite end. Form. At this time, the core part 2 wound in a desired size may be placed under the pillow as it is, or as shown in FIG. Anyway. Thereby, the soft core part 2 which consists of the same material as the pillow cover part 1 will be provided in the edge of the one side of the pillow 13. When sleeping in this state, the gap of the lower half of the cervical vertebra is filled with pressure enough to allow the winding core 2 to touch the cervical vertebra, so that light support is provided, the cervical spine is maintained, the airway is secured, and muscles are secured. It can relieve tension of muscles and nerves and induce deep sleep without squeezing the skin or under the tissues, and can ease numbness and pain from the neck to the shoulder. Since the pillow cover 1 is fixed to the pillow 13 with the band 4, the pillow cover is not detached from the pillow 13 by turning over while sleeping, and the positional relationship with the pillow 13 is not shifted. Moreover, since the core part 2 can be used even if it mounts on the pillow 13, and it can also adjust height by changing the frequency | count of winding depending on the case, according to a user's liking. Can be used. The height of the winding core part 2 can be stopped at any height and number of turns without being hung on the band 9.

  In addition, since the height can be freely adjusted by changing the number of windings of the winding core part 2, the user can set the height of the winding core part 2 that is most suitable for the user. Furthermore, since the cervical vertebrae can be supported by the both side parts 6 which are stiffer than the central part 5 of the winding core part 2 even when turned sideways, the posture of the cervical vertebra can be maintained. The pillow cover portion 1 is particularly dirty with sebum and hairdressing material secreted from the scalp, and therefore needs to be washed to keep it hygienic. Therefore, at the time of washing, the core 9 can be washed after the band 9 is removed and the core 2 is unwound so that the whole is made into a single fabric. This allows easy washing. Moreover, since the four corners 8 of the folding are not closed, washing dust and debris do not collect in the folding part, which is hygienic. Further, when the folded portion is fastened with a hook 13 or the like, the folded portion can be widened by removing the hook 13, so that washing is easier and washing dust is not easily collected.

  In the case of a person who does not have a habit of using the pillow 13, lay a pillow cover directly on a sheet (not shown), place the head on the pillow cover 1 and place the winding core 2 on the cervical vertebra. It can also be used in this way. Even in this case, the cervical vertebra is lightly supported so as to fill the gap below the cervical vertebra, and the function as a pillow cover can prevent the sheets and the like from being soiled by sebum or hair dressing of the head.

  In addition, the pillow cover of the present invention is easy to carry because it is foldable and lightweight, so it is not limited to use when sleeping on a futon, and depending on the case, it sits on a seat in a car or train You can use it when you are. For example, by using a band that is applied to the pillow at the end of the pillow cover, the pillow cover can be attached to the headrest portion of the seat and used in a sitting posture.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in the pillow cover of the present embodiment, a folded portion having the same width is formed across the pillow cover portion 1 and the winding core portion 2, and the pillow cover portion 1 also has a single cover material and a double portion. However, in the portion that becomes the pillow cover portion 1, the width of the folded portion is set to a width to be abutted with each other, or the thickness of the entire pillow cover portion 1 is constant without providing any folding. May be provided.
