Description

  The present invention relates to a pillow, and more particularly to a pillow that protects the oral cavity.

  Conventionally, pillows suitable for each posture have been proposed for those who sleep in a sideways, supine or prone posture. For example, as a pillow suitable for sleeping in a horizontal posture, a pillow having a hollow ear portion has been proposed (see Patent Document 1). According to this, when watching a television or the like lying down, it can be used while wearing glasses, and an effect can be obtained such that the ear is pressed against the pillow so that the ear does not hurt.

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

  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 adverse effects on the oral cavity area, but on the other hand, there are some people who can not get a good sleep unless they are in a sideways posture, For users with sideways wrinkles, the user's head can be stably supported even in a horizontal posture to maintain good sleep, while at the same time adversely affecting the oral cavity due to the horizontal posture It is necessary to prevent this.

Paying attention to this issue, the applicant firstly supported the user's head while sleeping sideways, while maintaining a good sleep, while the pillow was sleeping sideways. We proposed a pillow that protects the oral cavity by preventing the user's jaw from hitting and reliably preventing the sleeping habit of sleeping sideways from adversely affecting the oral area of the user. (See Patent Document 2).
In addition, as a pillow which paid attention to the same subject, there is one disclosed in Patent Document 3.

It comprises a fiber sheet layer, and is covered with a pillow cover in a state where the layers are laminated.

  In this case, a pocket-shaped storage part that stores the fiber sheet constituting the neck height adjusting fiber sheet layer can be formed in the towel sheet layer.

According to the pillow for protecting the oral cavity of the present invention, the top side portion in which the plane supporting the user's occipital region is formed in an elongated, substantially rectangular shape, and the plane supporting the user's ear periphery and neck are upside down. Since the neck side part formed in a substantially trapezoidal shape is integrally arranged so as to be lined up and down, it can be used while supporting the user's head stably even in a sideways posture An adverse effect on the oral cavity of a person can be reliably eliminated.
Then, the breathable core material layer, the quilting sheet layer and the towel sheet layer, which are integrally formed in the planar shape of the parietal side portion and the neck portion, and the planar shape of the neck portion. The neck sheet height adjustment fiber sheet layer is provided and covered with a pillow cover in a state in which the respective layers are laminated, so that the shape can be obtained by appropriately setting the thickness and the number of laminated layers constituting each layer. The pillow which protects the oral cavity which can respond to many users with different body shapes can be provided.

  Moreover, the fiber sheet which comprises the fiber sheet layer for neck height adjustment by forming the pocket-shaped storage part which accommodates the fiber sheet which comprises the fiber sheet layer for neck part height adjustment in the said towel sheet layer Can be stably disposed.

It is explanatory drawing which shows the usage pattern of the pillow which protects the oral cavity of this invention.

  Hereinafter, embodiments of the pillow for protecting the oral cavity of the present invention will be described with reference to the drawings.

In FIG. 1, one Example of the pillow which protects the oral cavity of this invention is shown.
The pillow 1 that protects the oral cavity includes a parietal side portion 11 in which a plane that supports the user's occipital region is formed in a substantially rectangular shape, and a plane that supports the user's ear periphery and neck is upside down. The neck side portion 12 formed in a substantially trapezoidal shape is integrally arranged so as to be aligned in the vertical direction, and is integrally formed in the planar shape of the parietal side portion 11 and the neck side portion 12. A core layer 2 having air permeability, a quilting sheet layer 3 and a towel sheet layer 4, and a neck sheet height adjusting fiber sheet layer 5 formed in a planar shape of the neck portion 12, and It is covered with a pillow cover 6 in a laminated state.

In this case, the core material layer 2 can be composed of, for example, a structure formed by entwining synthetic resin fibers in a three-dimensional shape. More specifically, as the synthetic resin, thermoplastic polyester or heat A structure using a plastic polyester elastomer (for example, “Breath Air” (registered trademark) manufactured by Toyobo Co., Ltd.) can be suitably used.
The thickness of the core material layer 2 (single layer) is preferably set to 1 to 5 cm, preferably 1.5 to 3 cm, more preferably about 2 cm.
Further, the core material layer 2 is composed of one layer in this embodiment (soft type for men) and the second modified embodiment (for women) shown in FIG. 3, and the first modified embodiment (for men) shown in FIG. In the case of (hard type), the number of layers can be arbitrarily set so as to be composed of two layers.
This core material layer 2 has good breathability, cushioning performance, water permeability, durability, environment / safety, and antibacterial performance imparting ability. Appropriate cushioning can be imparted by pressure dispersibility and excessive head sinking can be prevented.
In addition to the above-described materials, the core material layer 2 may be made of a breathable material such as a polyester fiber solid cotton cushion body or a foamed polyurethane cushion body.

The quilting sheet layer 3 is obtained by quilting a polyester wadding sheet, a polyester wadding and cotton wadding mixed sheet, or a laminated sheet of these, and more specifically, wadding having a basis weight of about 400 g / m ² can be used. .
The thickness of the quilting sheet layer 3 (single layer) is preferably set to 1 to 2 cm, preferably 1.5 to 1.8 cm, and more preferably about 1.7 cm.
In addition, the quilting sheet layer 3 is composed of three layers in this embodiment, and is composed of two layers in the first modified embodiment shown in FIG. 2 and the second modified embodiment shown in FIG. Can be set arbitrarily.
In addition to the softness of the cotton sheet, the quilting sheet layer 3 can impart durability to the cotton sheet by quilting and can gently support the weight of the head.

The towel sheet layer 4 is formed by overlaying a plurality of cotton towels (for example, four) and sewing the periphery.
The thickness of the towel sheet layer 4 (single layer) is preferably set to 0.5 to 2 cm, preferably 0.8 to 1.5 cm, and more preferably about 1 cm.
This towel sheet layer 4 can absorb sweat and vapor from the head and absorb moisture due to the good hygroscopicity and water absorbency of cotton, thereby creating a comfortable environment.
In addition, although the towel sheet layer 4 is provided in the uppermost layer in this embodiment, for example, by providing it between the quilting sheet layers 3, one layer of softness can be imparted to the pillow 1. .

As the neck height adjusting fiber sheet layer 5, a fiber sheet, for example, a polyester cotton sheet (nonwoven fabric sheet) can be suitably used.
The thickness of the neck height adjusting fiber sheet layer 5 (single layer) is preferably set to 0.3 to 0.8 cm, and preferably about 0.5 cm.
The neck height adjusting fiber sheet layer 5 is composed of four layers in this embodiment and the first modified embodiment shown in FIG. 2, and is composed of two layers in the second modified embodiment shown in FIG. As shown, the number of layers can be arbitrarily set.
In this case, it is desirable that the fiber sheet constituting the neck height adjusting fiber sheet layer 5 is formed so that the upper layer has a larger planar shape and the lower layer has a smaller one.
The neck height adjusting fiber sheet layer 5 can finely adjust the neck portion 12 of the pillow 1 to an arbitrary height.

By the way, the core material layer 2, the quilting sheet layer 3, and the towel sheet layer 4 are integrally formed in the planar shape of the crown side portion 11 and the neck side portion 12, while the fiber sheet layer for adjusting the neck height. Since 5 is formed in the planar shape of the neck portion 12, the fiber sheet constituting the neck height-adjusting fiber sheet layer 5 is simply laminated as it is, and there is a possibility that displacement occurs.
For this reason, in the present embodiment (the same applies to the first modified embodiment shown in FIG. 2 and the second modified embodiment shown in FIG. 3), the fiber sheet layer 5 for adjusting the neck height is provided on the towel sheet layer 4. A pocket-shaped storage portion 41 for storing the fiber sheet to be formed is formed.
Thereby, the fiber sheet which comprises the fiber sheet layer 5 for neck height adjustment can be arrange | positioned stably.

The pillow cover 6 that covers the layers in a laminated state can use a cloth made of any material made of woven fabric or knitted fabric. For example, a polyester material excellent in sweat absorption and thermal conductivity (for example, Toyobo Co., Ltd.) “Dry ice” (registered trademark) manufactured by Unitika Technos Co., Ltd. and “Cubic Eye” (registered trademark)) can be suitably used.
The pillow cover 6 can be freely opened with a fastener or the like so that the user can adjust the shape and hardness, and the thickness and the number of layers constituting each layer can be appropriately set (changed). I am doing so.

The pillow 1 that protects the oral cavity includes a parietal side portion 11 in which a plane that supports the user's occipital region is formed in a substantially rectangular shape, and a plane that supports the user's ear periphery and neck is upside down. Since the neck-side portion 12 formed in a substantially trapezoidal shape is integrally arranged so as to be lined up and down, even in the upward sleeping position shown in FIG. ), The adverse effect on the oral region of the user can be reliably eliminated while stably supporting the user's head.
Then, the air-permeable core material layer 2, the quilting sheet layer 3, the towel sheet layer 4, and the cervical side portion 12, which are integrally formed in the planar shape of the parietal side portion 11 and the cervical side portion 12. It is provided with a fiber sheet layer 5 for adjusting the neck height formed in a shape, and is covered with a pillow cover 6 in a state where the respective layers are laminated, so that the thickness and the number of laminated layers constituting each layer are appropriately set. By doing so, it is possible to easily adjust the shape and hardness, and thus it is possible to provide a pillow that protects the oral cavity that can be used for many users with different body shapes and the like.
In particular, the pillow 1 that protects the oral cavity quickly releases the moisture in the pillow 1 to the outside by the core material layer 2, imparts an appropriate cushioning property by good body pressure dispersibility, and excessive head sinking In addition to being able to prevent, in addition to the softness of the cotton sheet, the quilting sheet layer 3 can impart durability to the cotton sheet by quilting and can gently support the weight of the head. Is.
Moreover, since it forms integrally in the planar shape of the parietal side part 11 and the neck part 12, the surface of the pillow 1 becomes flat and can be turned over easily during sleep.
The pillow 1 for protecting the oral cavity is made of a material that can be washed by a washing machine, and the pillow 1 can always be used cleanly.

  As mentioned above, although the pillow which protects the oral cavity of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, The structure suitably in the range which does not deviate from the meaning. Can be changed.

  The pillow for protecting the oral cavity of the present invention can surely eliminate adverse effects on the oral cavity area of the user while stably supporting the user's head even in a horizontal sleeping posture, and can adjust the shape and hardness of the pillow. Since it has the characteristic of being able to cope with many users with different body shapes by making it easy to perform, it is usually used in addition to the use of medical pillows It can also be suitably used for pillow applications.
