Description

  The present invention relates to a pillow for people who are trapped in sleeping mainly in a sideways posture.

  Conventionally, pillows suitable for each posture have been proposed for a person who goes to sleep in a sideways, supine, or prone posture. For example, Patent Document 1 proposes a pillow having a hollow ear part as a pillow suitable for sleeping in a horizontal posture. According to this, it is said that effects such as being able to be used while wearing glasses when lying down and watching the television, etc., and preventing the ear from being painful by being pressed by the pillow are obtained.

JP 2000-139655 A

  However, when sleeping in a sideways posture using the pillow proposed in Patent Document 1, the user's chin and cheeks also hit the pillow and are pressed by the pillow, but such a state continues for a long time. And often have a serious adverse effect on the oral region.

  That is, in general, when force is continuously applied to the bone, even with a force of only 5 mg, the bone causes additional resorption by the action of osteoclasts and osteoblasts, the bone changes its form, and the tooth changes its position. Yes. The weight of a human head is about 5 kg for an adult, and the lateral force applied to the molars when lying on the side is 30 to 200 g. Therefore, if you lie down sideways for 8 hours, a force several times to several tens of times greater than the force at which the teeth start to displace (the above 5 mg force) will continue to be applied for a third of the day. So, of course, the teeth move and lead to the destruction of the dentition. That is, when such a sleeping state such as lying sideways continues, for example, to various oral regions such as tooth axis inclination, dentition deformation, occlusal plane asymmetry, jaw position displacement, facial twist, etc. Adverse effects will occur.

It can be said that it is better to avoid sleeping in a sideways posture from the viewpoint of such an adverse effect on the oral cavity region, but there is also a person who can not sleep well unless it is in a sideways posture. Therefore, for users with such sideways sleeping habits, they can support the sleeping person (user) 's head stably and maintain good sleep even in the horizontal position, while at the same time It is necessary to prevent adverse effects on the oral cavity region due to posture.
The present invention has been made paying attention to such a problem of the prior art, and stably supports the head of the user who is sleeping sideways while maintaining a good sleep even when in a horizontal posture. It is possible to prevent the pillow from hitting the jaw of the user who is sleeping sideways and to surely prevent the sleeping state of sleeping sideways from adversely affecting the oral area of the sleeping person (user). It aims at providing the pillow which protects an oral cavity.

  The pillow for protecting the oral cavity according to the present invention for solving such a problem is a parietal side bag body containing predetermined contents for supporting the back of the user's head, and has a substantially rectangular shape with an elongated plane. Left and right side of the user's forehead from the left or right side of the user's forehead (the temple or its vicinity) through the back of the head The parietal bag, and the user's ear periphery and neck, which are formed to have a length that is approximately the same as or larger than the distance to the temple or the vicinity thereof (for example, about 2 to 3 cm). A cervical side bag body in which predetermined contents are placed, and (a) the upper end portion is sewn so as to be adjacent to the neck side of the parietal side bag body (B) the plane is connected It is formed in a substantially trapezoidal shape that is reversed in the downward direction, and (c) diagonal directions from the portions near the left and right ends of the parietal side bag body toward the center of the user's torso, on both the left and right sides (left and right ends) Are formed by a substantially arcuate (curved) or substantially linear boundary line, and a defected portion facing the user's jaw when the user sleeps sideways is formed ( d) The length in the vertical direction as viewed from the entire user is substantially the same as “the vertical length of the user's neck, ie, the distance from the user's ear or its periphery to the shoulder” or this (E) a length in the left-right direction as viewed from the user near the parietal bag body side. User's length A length approximately equal to or close to the distance from one ear to the right through the back of the head to the other ear (for example, an approximate length formed by adding or subtracting 1 to 2 cm) And (f) the length of the portion away from the parietal bag side is the length in the left-right direction when viewed from the user, from the occipital side of the left or right jaw of the user to the back side of the neck Is approximately the same as the distance to the occipital side of the other jaw through or a length similar to this (for example, an approximate length formed by adding or subtracting 1 to 2 cm) A concave portion having a substantially V-shaped cross section formed along the left-right direction as viewed from the user at the neck portion side bag body, the boundary portion between the parietal side bag body and the neck portion side bag body and the vicinity thereof. And approaching the parietal bag from the neck bag Therefore, it is characterized in that it includes a recess including an inclined portion that is formed so as to be inclined in a direction away from the user and in which the user's ear portion is disposed when the user is in a lying posture. .

Further, the pillow for protecting the oral cavity according to the present invention is such that the parietal bag body supporting the user's occipital region and the neck side bag body supporting the user's ear periphery and neck portion are aligned in the vertical direction as viewed from the user. The oral cavity is made individually to fit the shape and size of the head of each individual user A by measuring the shape and size of the head for each specific user A. (A) a parietal bag body in which a predetermined content for supporting the back of the head of the user A is placed, and the plane is formed in a substantially rectangular shape, and the user Whether the length in the left-right direction as viewed from A is substantially the same as the distance from the left or right side of the forehead of the user A to the left or right side of the forehead of the user A through the back of the head Head that is formed to be longer than this A side bag body, and (B) a neck side bag body that is arranged adjacent to the parietal side bag body and that contains predetermined contents for supporting the ear periphery and neck of the user A (A) its upper end is connected to the neck side of the parietal bag body, (b) its plane is formed in a substantially trapezoidal shape upside down, and (c) its left and right sides On both sides, “a missing portion defined by a substantially arcuate or substantially linear boundary line in an oblique direction from the portion near the left and right end portions of the parietal side bag body toward the user A's torso center direction, When the user A sleeps sideways, a missing portion facing the jaw of the user A is formed, and (d) the length in the vertical direction when viewed from the user A is “the user A The length of the neck of the user in the vertical direction, that is, the ear of the user A Is a length substantially the same as or close to the distance from the peripheral part to the shoulder ", and (e) the left and right sides of the part close to the parietal bag side as viewed from the user A The length in the direction is a length approximating the distance from the left or right ear part of the user A to the other ear part via the back of the head and the length in the left-right direction as viewed from the user of the parietal bag body. (F) the length in the left-right direction as viewed from the user A of the portion away from the parietal bag body side is either the left or the right of the user A The cervical side is formed to have a length approximately the same as or a length similar to the distance from the occipital side of the jaw to the occipital side of the other jaw through the back of the neck. And a boundary between the parietal side bag and the cervical side bag A concave portion having a substantially V-shaped cross section formed in the left and right direction when viewed from the user A, and “the user as the neck side bag body approaches the parietal side bag body” It is manufactured by forming a concave portion including an inclined portion where the user A's ear portion is disposed when the user A is in a sideways posture and is inclined away from A.
Furthermore, in the present invention, a granular body formed into a substantially spherical shape having a diameter of 2 to 7 mm by entwining a large number of natural fibers or chemical fibers in the parietal side bag body and the neck side bag body. However, it is desirable that a large number are accommodated. Furthermore, in the present invention, it is desirable that one or a plurality of flexible bags enclosing a gel-like cold insulating agent are accommodated in the parietal side bag and the neck side bag.

1. Advantages and Effects of the Present Invention (1) According to the configuration of the present invention (the parietal side bag, the neck side bag, and the recess), the user (sleeper) uses the pillow according to the present invention. When going to bed in the horizontal direction, as will be described in detail later, the positional relationship in the vertical direction and the horizontal direction between the user's head and neck side bag can always be kept constant.
(2) Therefore, according to the present invention, even when the user is in the sideways posture,
(A) The portion excluding the front from the user's head jaw (the rear side of the forehead, the ear periphery, and the neck) is always securely placed on the parietal bag and the neck bag. Therefore , the user's head can always be supported stably ,
(B) Since the user's jaw (the part facing the teeth) is surely opposed to the defect (cavity), the user's jaw does not hit the pillow, and the user's jaw is It is possible to reliably prevent the teeth from being compressed (the dentition is deformed by the compression) .
(3) That is, in order to prevent the sleep state of the user's sideways sleep from adversely affecting the user's oral region (dentition / jaw), “the pillow does not hit the user ’s jaw” "(The pillow does not press the jaw)", but even if you simply make a "pillow that does not hit the user's jaw" (does not press the jaw) " The pillow cannot stably support the user's head and enjoy a comfortable sleep.
Therefore, in the present invention, by adopting the special configuration as described above (the above-mentioned parietal side bag, neck side bag, and recess), the user's head and neck side bag are separated from each other. The positional relationship between the vertical direction and the horizontal direction is always kept constant, thereby stably supporting the user's head and simultaneously “the pillow does not hit the user ’s jaw” (= the pillow does not touch the jaw) It is possible to “do not press” .
(4) In summary, according to the present invention, (a) even when the sleeping person (user) is in the horizontal posture, the user's head who is sleeping sideways is stably supported to maintain good sleep. However , at the same time, (b) the sleeping posture of sleeping sideways, which prevents the pillow from “striking” the user's jaw while lying sideways, will adversely affect the oral cavity area of the sleeping person (user) Can be surely prevented.

2. Details of the operation and effect of the present invention The details of the operation and effect of the present invention will be described as follows.
(1) Vertical positional relationship between the user's head and neck side bag body In the present invention, the neck side bag body supporting the user's ear peripheral part and neck part as viewed from the whole user is vertically The length of the direction is substantially the same as or similar to the length of the user's neck in the vertical direction, that is, the distance from the user's ear or its periphery to the shoulder. (In addition, the cervical side bag body 2 has a raised shape (convex shape) that conforms to the concave shape of the back side or side of the user's neck (the part from the ear to the shoulder). Therefore, the neck side bag body is always positioned and held in a state of being sandwiched between the user's ear periphery and the shoulder. As a result, the positional relationship in the vertical direction when viewed from the user between the cervical side bag body and the user's head (particularly the ear periphery and neck) is always kept constant (positioned). Become .
In the present invention, a concave portion having a substantially V-shaped cross section formed along the left-right direction as viewed from the user is formed around the boundary between the parietal-side bag and the neck-side bag. When the user is sleeping on his / her back or sideways, the most protruding part (convex part) of the user's occipital or temporal region will enter the concave part. , The most protruding part (convex part) of the user's occipital or temporal region is always positioned in relation to the concave part, and as a result, the neck side bag body and the user's head (particularly, The positional relationship in the vertical direction with respect to the ear peripheral part and the neck part is always held (positioned) constantly .

(2) Positional relationship between left and right direction of user's head and neck side bag body In the present invention, the head side bag body side of the neck side bag body supporting the user's ear periphery and neck The length in the left-right direction as viewed from the user near the user is approximately the same as or similar to the “distance from the user's left and right ears to the other ear via the back of the head” The length in the left-right direction of the portion formed and separated from the parietal bag body side is “the other jaw part from the rear side of the user's jaw part through the back side of one of the left and right neck parts The distance to the back side of "is approximately the same length or approximate length, so whenever a user is in a sideways position (via a supine position) The side facing the front of the face from the user's ear (that is, the jaw) is the defect (cavity). Opposed jaws of the user does not contact the pillow (the jaw of the user facing the defect) will be.

(3) Operational effects of the inclined portion In the present invention, the user's ear is disposed in a portion of the neck side bag close to the parietal side bag when the user is in a lying position. Since the slope is formed , the user's ears always enter the slope when the user takes a lying-down posture, so the user may experience pain or inconvenience due to the ears being pressed against the pillow. There is no sense of pleasure, and the user's ear part always enters (positions) into the inclined part, so that the positional relationship between the user's ear part and the inclined part, that is, the neck side bag body is always constant. Held (positioned) . Therefore, when the user is in a sideways posture, the user's chin is always opposed (positioned) to the defect (cavity), and the user's chin is pressed with a pillow to apply force. This is more reliably prevented. In the present invention, the inclined portion constitutes a part of the concave portion.

Thus, in the present invention, the vertical positional relationship and the horizontal positional relationship between the cervical side bag and the user's head (particularly the ear and neck) are always constant. When it is held (positioned) and the user is lying down , the side facing the front of the face from the user's ear (that is, the portion including the jaw) always faces the defect (the pillow is the user It will not hit the jaw of the) . Therefore, according to the present invention, when the user goes to bed in either the left or right direction, the user's chin is pressed by the pillow and force is applied to the oral cavity area (displacement of dentition, etc.). Can always be reliably prevented.

3. In addition, in the present invention, in the present invention, a large number of natural fibers or chemical fibers are entangled with each other inside the parietal side bag body and the cervical side bag body to form a substantially spherical shape having a diameter of 2 to 7 mm. When a large number of formed granular materials are contained (enclosed), the portion corresponding to the user's head is not recessed more than necessary, and the user's head is stably held. Can promote comfortable sleep. Further, in the present invention, when one or a plurality of flexible bags enclosing a gel-like cooling agent are accommodated in the parietal side bag and the neck side bag, the head The head can be cooled and the introduction of sleep can be promoted while stably holding.

It is a front view when the present Example 2 is seen from the neck side bag body side.

  The best mode for carrying out the present invention is a mode as described in Example 1 below.

1. Configuration of Example 1 Fig. 1 is a perspective view showing a pillow for protecting the oral cavity according to the present invention, Fig. 2 (a) is a plan view of the pillow according to Example 1, and Fig. 2 (b) is a futon. FIG. 3 is a front sectional view of the pillow according to the first embodiment viewed from the cervical side bag body side (virtual state when the first embodiment is floating in the space). Diagram).
In FIG. 1-3, 1 is a parietal bag for supporting the user's occipital region (for mounting the back or side of the user's head), and 2 is the user's ear periphery and neck. Neck-side bag for supporting ("the user's part between the ear periphery and shoulder including the back of the neck"). Opening and closing portions 11 and 12 including fasteners for opening and closing the bag body are formed in the parietal side bag body 1 and the neck portion side bag body 2, respectively.
In Example 1, the upper and lower cloths at the center (boundary portion 3 in FIGS. 1 and 2) of one bag body prepared in advance were sewn and separated into two bag bodies. These are referred to as the parietal side bag body 1 and the cervical side bag body 2, respectively.

In Example 1, a large number of natural fibers are entangled with each other as contents (stuffing) inside the parietal side bag body 1 and the cervical side bag body 2 via the opening / closing parts 11 and 12. Thus, a large number of granular bodies (granular wool) formed into a substantially spherical shape with a diameter of 2 to 7 mm are filled and enclosed (accommodated). In the present Example 1, as this granular material, for example, “Le Berceau Blanc” (trademark), which is a granular wool manufactured by Koike Keishoku Dying Co., Ltd. (2833 Nishinomiyacho, Ashikaga, Gunma) Are filled and enclosed (accommodated) inside the parietal side bag body 1 and the cervical side bag body 2. (In this way, when the fibrous granular wool is filled and sealed in the parietal side bag body 1 and the cervical side bag body 2, the head of the user who uses them is stably held. And can promote comfortable sleep).
In Example 1, instead of the flexible bag enclosing the fibers, a flexible bag enclosing a gel-like cooling agent may be used. As this gel-like cold-retaining agent, for example, “COOL TIME (Cool Time)” (trademark) manufactured by Pearl Metal Co., Ltd. (190, Gojo, Sanjo-shi, Niigata Prefecture) in which a transparent gel-like cold-reserving agent is enclosed in a plastic bag. (In this way, when a flexible bag body in which a cooling agent is sealed is put in the parietal side bag body 1 and the cervical side bag body 2, these are used. You can cool the head while holding the user ’s head in a stable manner to promote sleep).
Moreover, in this Example 1, instead of the bag body in which the fibers are encapsulated or the bag body in which the fibers are encapsulated, fillings (contents) such as resin fine rings, beads, and buckwheat shells used in conventional pillows ) May be housed inside the parietal side bag body 1 and the cervical side bag body 2.

  Further, as shown in FIG. 2 (a), the parietal bag body 1 has a substantially rectangular plane, and the length of the long side in the horizontal direction in the figure is either left or right of the user's forehead. The distance (for example, about 30 to 36 cm) from one side (the temple or the vicinity thereof) to the left or right side (the temple or the vicinity thereof) of the user's forehead through the back of the head Larger length (for example, about 60 cm or less, which is a common size for a long side pillow), that is, about 30-60 cm (more desirably about 30-50 cm), in this embodiment about 42 cm. Is formed. In addition, the short side of the parietal bag body 1 in the vertical direction in the drawing is long enough to support the user's back head, for example, about 8 to 20 cm, more preferably about 8 to 15 cm. In addition, in this embodiment, it is formed to be about 9.5 cm (note that the above-mentioned about 9.5 cm is the size when seen from the plane when the content is enclosed inside, The length of the short side when the is not enclosed is about 11 cm).

  Moreover, as shown to Fig.2 (a), the said neck part side bag body 2 is formed in the substantially trapezoid shape where the whole plane was reverse. Further, the cervical side bag body 2 has a length in the vertical direction in the drawing substantially the same as “the length of the user's neck, that is, the distance from the user's ear or its periphery to the shoulder”. The length is approximately 9 to 15 cm, more desirably about 10 to 14 cm, and in this embodiment about 12 cm. (In addition, about 12 cm is the content inside. This is the size when viewed from the plane when enclosing the object, and the length in the vertical direction when the contents are not encapsulated is about 14 cm. (The same applies to the following) indicating “size when viewed from the plane when the contents are enclosed in FIG.

Further, as shown in FIG. 2A, the neck side bag body 2 has an upper side (side of the portion in contact with the parietal side bag body 1 = side in the left-right direction along the boundary portion 3 described later) 2a. Is substantially the same length (for example, about 30 to 34 cm) as the distance from the left and right ears of the user to the other ears via the back of the head, or a length approximating this. (For example, about 28 to 38 cm) and a length substantially the same as the length in the left-right direction when viewed from the user of the parietal bag body 1 (for example, about 30 to 60 cm as described above) It is formed in about 28 to 60 cm (or about 30 to 60 cm), more desirably about 28 to 50 cm, and in this embodiment, about 42 cm which is the same as the long side of the parietal bag body 1 (FIG. 2 (a ) Shows the case of about 42 cm).
Further, the neck side bag body 2 is a portion close to the parietal side bag body 1 side (a portion slightly lower than the side 2a in contact with the parietal side bag body 1; indicated by reference numeral 5 in FIG. 2). The length of the part in the horizontal direction in the figure is substantially the same as the distance from the left and right ears of the user to the other ears via the back of the head (for example, about 30 to 34 cm) or this (The length is shorter than the upper side 2a, for example, about 26 to 36 cm).
Further, the neck side bag body 2 has a lower side (a part away from the parietal bag body 1 side) 2b in the left-right direction in the figure, so that the neck of the neck part from the occipital side of one of the left and right jaws of the user. Approximately the same length (for example, about 20 to 24 cm) or a similar length (for example, about 18 to 26 cm (or about 20 to about 20 to 20 cm) to the occipital region of the other jaw through the back side of the part 26 cm)), and in this embodiment, it is formed to 23 cm.

  Moreover, as shown in FIG.2 (b), the said parietal bag 1 is formed in the thickness of 3.5 cm, for example. The neck side bag body 2 is formed to have a thickness of, for example, 4.5 cm. Thus, in Example 1, the thickness of the neck side bag body 2 is formed to be larger than the thickness of the parietal side bag body 1 (see also FIG. 3). In particular, the neck portion of the user's neck (neck) and shoulders can be fully absorbed by the neck side bag body 2 when the user is lying down sideways, and the user's neck (neck) and shoulder are stably supported. This is to make it possible.

  In FIG. 1-2, 3 is a boundary part (partition line part) between the parietal side bag body 1 and the neck side bag body 2, and 4 is the left and right ends of the neck side bag body 2 shown in the figure. Each of these is a missing portion (hollow portion) having a shape (or a substantially triangular shape) like a part of a circular plate (circular shape) including an arc. As shown in FIG. 2 (a), the defect portion 4 is shown in the center of the neck side bag body 2 from the left and right upper ends (portions near or in contact with the parietal bag body 1) 4a. Notched by the curved substantially arc-shaped curves 4c respectively facing the left and right lower end portions 4b that are obliquely downward (toward the user's torso center) (by the curved substantially arc-shaped curves 4c as described above) The boundary between the defect portion 4 and the cervical side bag body 2 is defined). Thereby, the said defect | deletion part 4 is formed in the shape like a part of disk (circle) containing an arc as shown in figure (In addition, in this invention, the said substantially arc-shaped curve 4c is A substantially straight line may be sufficient, and the said defect | deletion part 4 may be a substantially triangular shape instead of a shape like a part of disc (circle).

  Moreover, in FIG. 2 (a) (b), 5 is formed in the vicinity part (refer the shaded part by the broken line of FIG. 2 (a)) of the said boundary part 3 of the said neck part side bag body 2, It is an inclined part that is thinner than the other part and is inclined (declined obliquely) toward the boundary part 3. In FIG. 2B, 13 is a futon or a bed mattress. Moreover, in FIG. 2, the recessed part 6 is formed in the vicinity part of the boundary part 3 of the said parietal side bag body 1 and the said neck side bag body 2, and when a user is lying on the back or sideways, The most protruding part (including the peripheral part of the ear) of the user's occipital region or temporal region enters the recess 6. In the first embodiment, the inclined portion 5 constitutes a part of the concave portion 6.

2. Operation of first embodiment Next, the operation of the first embodiment will be described with reference to FIG. 4-9.
(1) Vertical positional relationship between the head of the user 10 and the cervical side bag body 2 First, FIGS. 4 and 5 show the posture of the user lying sideways using the pillow according to the first embodiment. It is a figure which shows the state which has taken the supine attitude | position as a pre-stage. 4 and 5, the user 10 places the neck (neck) and the back side of the ear 10 a on the neck-side bag body 2, and the top of the back of the head on the top of the head-side bag 1. It is on. In this state, as suggested from FIGS. 4 and 5, in the first embodiment, the vertical lengths of the parietal side bag body 1 and the cervical side bag body 2 in the figure are the length of the head of the user 10. The length in the illustrated vertical direction (= the length from the top of the user to the shoulder through the neck) is substantially the same.

  Further, as shown in FIG. 4, in the first embodiment, the length in the illustrated vertical direction of the neck side bag body 2 is “the vertical length of the user's neck, ie, the length of the user's ear 10a. The distance from the vicinity of the upper end portion to the shoulder 10b is substantially the same as or approximate to the length (in the first embodiment, approximately 12 cm as described above). As a result, the cervical side bag 2 is always sandwiched between the user's ear 10a and the shoulder 10b so as to always face the neck of the user 10. Further, the cervical side bag body 2 always has a raised convex portion (a portion having a large thickness at the center of the cervical side bag body 2 in FIG. 5) always at the user's neck (from the ear portion). It is designed to oppose and conform to the concave shape on the back and side of the part up to the shoulder. Therefore, in the first embodiment, even if the head of the user 10 is changed from the back to the left or right side on the first embodiment, or after that, the user moves unconsciously while sleeping. The positional relationship in the vertical direction between the user's 10 head (particularly, the ear periphery and neck) and the neck-side bag 2 is always held (positioned).

  In the first embodiment, the concave portion 6 is formed in the boundary portion 3 between the parietal-side bag body 1 and the neck-side bag body 2, and when the user is lying on his back or sideways, Since the most protruded portion of the user's occipital region or temporal region always enters the recess 6, the protrusion portion of the user's occipital region or temporal region is always related to the recess 6 from this point. As a result of always being positioned stably, the positional relationship in the vertical direction between the neck side bag body 2 and the peripheral part of the user's ear 10a and the neck is always held (positioned) constantly. It is like that.

(2) Positional relationship between the head of the user 10 and the cervical side bag body 2 in the left-right direction As shown in Fig. 4, in the first embodiment, the cervical side bag body 2 The length of the lower part of the figure (the lower side 2b) in the horizontal direction of the figure is "the rear side of the left or right jaw part of the user from the rear side of the left or right jaw part of the user through the back side of the neck part" It is formed to have a length that is substantially the same as or close to the “distance to reach” (about 23 cm as described above in the first embodiment). Therefore, in the first embodiment, even if the head of the user 10 is changed from the back to the left or right side on the first embodiment, or after that, the user unconsciously while the user is sleeping The jaw portion 10c of the user 10 always faces the deficient portion (cavity portion) 4 of the cervical side bag body 2 (see FIGS. 6 and 8). ).

  Further, as shown in FIG. 4, in the first embodiment, the length in the left-right direction of the neck portion side bag body 2 near the parietal side bag body 1 (the inclined portion 5) is “user 10 The distance from one ear portion 10a to the other ear portion 10a via the back of the head is approximately the same or approximate (approximately 34 cm as described above in the first embodiment). Therefore, in the first embodiment, even when the head of the user 10 is changed from the back to the left or right side on the first embodiment (when the user's head is rotated in the left-right direction). The right or left ear portion 10a of the user 10 is arranged at either the left or right end of the inclined portion 5 (the portion inclined slightly thinner than the other portion) of the neck side bag body 2 in the figure. (See FIGS. 6 and 8).

Thus, according to the first embodiment, the positional relationship in the left-right direction between the head of the user 10 (particularly, the right or left ear 10a and the neck) and the parietal bag 2 is always constant. As a result, even when the user 10 sleeps in a sideways posture, or after that, even if the user unconsciously rotates his / her head left and right while sleeping, the user's jaw 10c is always It is designed to face the defect portion 4 so that the jaw portion 10c of the user 10 does not hit the pillow, and the jaw portion 10c of the user 10 is always prevented from being pressed by the pillow . .

(3) Technical significance of the inclined portion 5 In the first embodiment, by forming the inclined portion 5, the head of the user 10 is either on the left or right side from the back on the first embodiment. As described above, the vertical positional relationship between the user's head and the cervical side bag body 2 is always constant even when the posture is changed to the horizontal direction (when the user's head rotates in the left-right direction). As a result, the user's 10 ear part 10a always faces the inclined part 5, so that the user 10 feels pain and discomfort due to the ear part 10a being pressed by the pillow. There is no need to do so.

(4) Summary of operation of the first embodiment As described above, in the first embodiment, the head 10 of the user 10 is formed by forming the neck side bag body 2 in the shape and size as described above. Position (particularly around the ear and neck) and the cervical side bag body 2 in the vertical and horizontal positional relationship, even if the posture of the head of the user 10 is unconscious while sleeping Even if it rotates, it can always be held constant (positioned).
Therefore, in the first embodiment, “the left and right sides of the forehead, the left and right ears 10a and their peripheral parts, and the neck (the back of the head) Is always disposed on the parietal side bag body 1 and the cervical side bag body 2 (for example, the left and right ears 10a of the user 10 always face the inclined part 5). Therefore, the user's head is always stably supported by the parietal side bag body 1 and the cervical side bag body 2, thereby ensuring a good sleep of the user.
Further, according to the first embodiment, even when the sleeping user 10 unconsciously changes the posture of the head from the back to the side (when the head is rotated in the horizontal direction), the “ The jaw part (part facing the dentition etc.) 10c "always faces the defect part (cavity part) 4, so that the user's jaw part 10c hits the pillow when lying on its side and the user's jaw part 10c is no longer compressed by the pillow, and the oral cavity region including the jaw portion 10c is reliably prevented from being adversely affected by the pressing force from the pillow (such as displacement of the dentition).

  In the first embodiment, for the two separated bag bodies 1 and 2, for example, the maximum thickness (for example, 3.5 cm) of the neck side bag body 2 (for example, the maximum thickness (for example, 3.5 cm) of the parietal side bag body 1). (4.5 cm) is formed larger. Accordingly, in the first embodiment, for example, as illustrated in FIGS. 7 and 9, when the user 10 sleeps in a horizontal posture, the thickness of the shoulder 10 b of the user 10 is set to the thickness of the neck side bag body 2. Therefore, the user 10 can go to bed comfortably in a natural posture even in the horizontal direction.

3. About Comparative Example Next, FIG. 10 is a diagram for explaining a pillow 21 of a comparative example of the first embodiment. That is, this comparative example (not a publicly known example) is, as in Example 1, “separated into two parts, the parietal side bag body 1 and the cervical side bag body 2, and the periphery of the boundary part 3. 10 is not a pillow having a recess 6 formed on it, but merely a pillow 21 in which a deficient portion (hollow portion) 21b defined by a substantially arc-shaped curved surface 21a is formed at the lower left and right ends of the figure as shown in FIG. In the following, assuming such a pillow as a comparative example, the operation (problem) when sleeping sideways using this pillow will be described.

(1) Vertical positional relationship between the head of the user 10 and the comparative example In the pillow 21 of the comparative example shown in Fig. 10, the user's ear periphery (upward) as in the first embodiment. There is an “independent (separate from the parietal bag) cervical bag” (see reference numeral 2 in FIG. 5 for the first embodiment) that faces the neck between the shoulder and the shoulder (downward). Not. Therefore, in the pillow 21 of this comparative example, the raised convex part (as shown in FIG. 5 etc.) corresponding to and conforming to the concave part of the user's neck (the part from the ear part to the shoulder). 1 swell portion of the neck side bag body 2) does not exist. Further, in this comparative example, the concave portion (the parietal side bag body 1 and the cervical side side bag body shown in FIG. No recess 6) between 2 is also present.

  Therefore, in the pillow 21 of this comparative example, the “vertical positional relationship” between the user's neck and the pillow of the comparative example is not always constant, and is always due to the unconscious movement of the user while sleeping. It will fluctuate randomly. Therefore, when such Comparative Example 21 is used, initially, as shown in FIG. 10A, the jaw portion 10c (the portion facing the dentition) 10c below the ear portion 10a of the user 10 is the defect. Even if it is in the correct position opposite to the portion (cavity portion) 21b, the jaw portion 10c of the user 10 is shifted upward in the figure due to the unconscious movement of the user 10 while sleeping, and FIG. 10 (b). In other words, the jaw portion 10c diagonally below the ear portion 10a of the user 10 faces and abuts against the pillow without facing the deficient portion (cavity portion) 4, and is pressed by the user. The attitude of lying sideways can have a significant adverse effect on the user's oral area.

(2) Positional relationship between the user's 10 head and the comparative example in the left-right direction Further, in the pillow 21 of the comparative example shown in FIG. As in the lower part of the neck side bag body 2 of Example 1 (the part away from the parietal side bag body 1) “from the back side of the left or right jaw part of the user through the back side of the neck part It is not formed to have a length (approximately 23 cm as described above in the first embodiment) that is substantially the same as or close to the distance to the rear side of the left or right jaw of the user. . In the comparative example 21, the length in the horizontal direction of the illustrated central portion is the right and left of the inclined portion 5 of the neck side bag body 2 of the first embodiment (see reference numeral 5 in FIG. 2A). The length of the direction is substantially the same or approximate to the “distance reaching the other ear 10a from one ear 10a of the user 10 via the back of the head” (in the first embodiment, approximately 34 cm as described above). It is not necessarily formed . Therefore, when using this comparative example, the user 10's unconscious movement during sleep causes the user's 10 ear portion 10a to shift in the left-right direction, that is, as shown in FIG. Further, even the ear portion 10a of the user 10 may end up facing the defect portion (cavity portion) 21b (in this way, even the ear portion 10a faces the defect portion. Since the pillow 21 of the comparative example cannot stably support the user's head and cannot give a good sleep to the user, the user 10 can hold his / her head, for example, upward in the figure. May shift to an inconvenient state as shown in FIG. 10B).

(3) Summary of operation of comparative example As apparent from the above (1) and (2), when the pillow 21 of the comparative example as shown in Fig. 10 is used, the user sleeps in a sideways posture. Sometimes it is quite hopeful that the user's head will be supported stably and the user will sleep well, or the user's chin will be compressed by the pillow and will not adversely affect the user's mouth. Can not.

  Next, FIG. 11 is a perspective view showing a second embodiment of the present invention, FIG. 12A is a plan view showing the second embodiment, FIG. 12B is a longitudinal sectional view thereof, and FIG. FIG. The second embodiment is basically the same as the first embodiment, but differs in the following points. That is, in the second embodiment, as shown in FIG. 12A, the top-side bag body 1 that supports the user's head is formed in a substantially rectangular plane, and the length in the horizontal direction in the drawing is long. The side is approximately the distance (for example, 32 to 34 cm) from the left or right side of the user's forehead (the temple or the vicinity thereof) to the other side (the temple or the vicinity thereof) through the back of the head. They are formed to have the same length (for example, an approximate length obtained by adding or subtracting 1 to 2 cm to the distance), for example, about 34 cm. Moreover, in the present Example 2, as shown to Fig.12 (a), the neck part side bag body 2 which supports a user's neck part is the upper side of the illustration left-right direction (it is close to the said head side bag body 1 side). The length (for example, 32 to 34 cm) from the left and right ears of the user to the other ear through the back of the head (for example, 32 to 34 cm) is approximately the same length (for example, 1 to the above distance). Approximate length of 2 cm plus or minus), for example, about 34 cm (34 cm substantially the same as the long side of the parietal bag body 1). Except for these points, the second embodiment is the same as the first embodiment. Therefore, this second embodiment can provide the same operational effects as the first embodiment.

  In the first and second embodiments described above, assuming a standard shape and size of a large number of users' heads, for example, for children, for adult women, for adult men, or It is assumed that pillows are designed to fit a plurality of preset standard shapes and sizes such as S, M, and L, mass-produced, and sold to a large number of users. On the other hand, the third embodiment measures the shape and size of the head of each specific user A, and individually attaches the pillow so as to match the shape and size of the head of the individual user A. It is assumed that it is produced.

  That is, in the manufacturing method of the third embodiment, (A) the parietal bag body 1 in which predetermined contents for supporting the back of the head of each individual user A are placed, and the plane is elongated in a substantially rectangular shape. When viewed from the user A, the length in the left-right direction extends from the left or right side of the forehead of the user A to the left or right side of the forehead of the user A via the back of the head. A parietal bag body 1 that is formed to have a length that is substantially the same as or greater than the distance to the head, and (B) the ear peripheral part of the user A that is arranged adjacent to the parietal bag body 1 And a cervical side bag body 2 in which predetermined contents for supporting the cervical region are placed, and (a) its upper end portion is connected to the cervical side of the parietal side bag body 1; (B) The plane is formed in a substantially trapezoidal shape upside down, and (c) both left and right sides thereof “The defect portion 4 is defined by a substantially arc-shaped or substantially straight boundary line in an oblique direction from the portion near the left and right ends of the parietal bag body 1 toward the center of the body of the user A, respectively. A deficient portion (cavity portion) 4 ”facing the jaw portion of the user A when the user A sleeps sideways is formed, and (d) the length in the vertical direction when viewed from the user A as a whole is formed. , “The length in the vertical direction of the neck of the user A, that is, the distance from the user A's ear or its peripheral part to the shoulder” is substantially the same as or similar to the length. (E) The length of the portion close to the parietal bag body 1 side in the left-right direction as viewed from the user A is from the left or right ear of the user A through the back of the head to the other ear Distance to reach and approximate length It is formed in any length between the length in the left-right direction as viewed from the user of the parietal bag body 1 and substantially the same length, and (f) apart from the parietal bag body 1 side. The length in the left-right direction when viewed from the user A is from the occipital side of one of the left and right jaws of the user A to the occipital side of the other jaw through the dorsal side of the neck. A cervical side bag body 2 formed to have a length substantially the same as or close to the distance (such as the parietal side bag body 1 and the cervical side bag body 2). At the same time as or after the formation), at the boundary portion 3 between the parietal side bag body 1 and the cervical side bag body 2 and in the vicinity thereof, it is formed along the left-right direction as viewed from the user A. A concave portion 6 having a substantially V-shaped cross section, which is “front side as the neck side bag body 2 approaches the parietal side bag body 1. The concave portion 6 including the inclined portion 5 "where the ear portion of the user A is disposed when the user A is in the horizontal sleeping posture is inclined in a direction away from the user A.

  The pillow manufactured by the above manufacturing method of Example 3 has the same shape as that described in Example 1 or 2, and the difference from Examples 1 and 2 is that Example 3 is virtual. It is only that it was made to fit each specific user A, not a simple user. The specific pillow manufactured by the manufacturing method of the third embodiment is the same as the pillow described in the first and second embodiments and illustrated in FIGS. 1-9 and 11-13. In the pillows shown in FIGS. 1-9 and 11-13, in the third embodiment, it is the first and second embodiments that the user 10 in FIG. 4-9 is not a virtual user but an individual specific user A. It is a different point. In addition, when manufacturing the pillow of the present Example 3, the said parietal side bag body and the neck part side bag body may each be produced separately, and they may be connected by sewing etc., or one bag. A body is created, and the pillow of the third embodiment is divided into a top side bag body 1 and a lower side neck part side bag body 2 by separating the upper body with a sewing center at a substantially central portion in the vertical direction when viewed from the user. You may make it form.

  As mentioned above, although each Example of this invention was described, this invention is not limited to what was described as each said Example, A various correction and change are possible. For example, in the first embodiment, the parietal side bag body 1 and the cervical side bag body 2 are arranged in a substantially central portion (a substantially central portion in the vertical direction when viewed from the user) of one bag body prepared in advance. The upper and lower two cloths are sewn together and partitioned by two bags as viewed from the user, the upper part and the lower part. However, the present invention is not limited to this. Two pillows each having a predetermined shape are prepared, and the pillows of the present invention comprising the parietal bag 1 and the cervical bag 2 are configured by connecting and connecting them by sewing or the like. It may be. Moreover, in the said Example 1, although the said parietal side bag body 1 and the said neck part side bag body 2 are formed in the dimension which was illustrated, respectively, this invention is limited to the illustrated dimension mentioned above. It can be configured as a size suitable for the height and physique of the user (actually, for children, for adult women, for adult men, S, M, L, etc.) It is desirable that the size is patterned along multiple types of Moreover, as the contents of the parietal side bag body 1 and the cervical side bag body 2, not only the granular wool or gel-like cold-retaining agent as in each of the above embodiments is used, but also a normal buckwheat shell Of course, the contents stored in the pillow may be used. Moreover, in the said Example, the boundary part with the said neck part side bag body 2 has a substantially circular arc shape (curve shape) in the said defect | deletion part (cavity part) (it is notched by the substantially circular arc boundary line). However, the defect portion in the present invention has a substantially straight boundary line with the cervical side bag body 2 (notched by the substantially straight boundary line), The planar shape may be a substantially triangular shape.
