Description

Functional gel pillow that can stably support the cervical spine and help sleep

The present invention relates to a functional pillow. Specifically, the present invention relates to a functional pillow comprising a buffer made of viscous gel, which can effectively support the cervical spine and help people have a good sleep.

Generally speaking, the cervical spine is the bony portion of the spine that forms the neck between the skull and thoracic vertebrae, and extends from the base of the skull to the upper thoracic vertebrae of the ribs.

A healthy neck should preferably have a C-shaped curve. If the cervical spine bends in the opposite direction and is kept straight (for example, as the time spent using a computer or mobile phone increases, the neck becomes straight), it may cause headaches, stiff shoulders, etc. If this posture is repeated and the neck is kept straight and stiff, it may cause cervical disc herniation or lumbar disc herniation in severe cases.

This posture may even occur during sleep. When the cervical spine is straightened during sleep, the nerves and blood vessels passing through the cervical spine will be compressed, resulting in metabolic disorders, making it impossible to have a good sleep.

In order to prevent the above problems, people gradually realize the importance of functional pillows, because functional pillows can prevent diseases such as herniated discs and help users' cervical spine, which is always in a wrong posture during the day, to obtain the correct C-shaped curve even when sleeping. Therefore, various types of functional pillows have been launched one after another.

Among all the functional pillows that have been launched, there is a memory foam pillow that uses injection molding, in which the part that supports the head is concave, and the part that supports the cervical spine protrudes upward, thus forming a C-shape to strengthen the support of the cervical spine. However, since the shape of the pillow is not naturally formed by the weight of the user's head, the pillow cannot actually reflect the different head shapes of each user, and therefore may make the user feel quite uncomfortable.

Another type of functional pillow proposed in the past is a cushion made of elastic material to support the user's cervical spine and head. The cushion is set on the entire surface of the pillow, or is set at the supporting parts of the head and cervical spine at the same time. However, there is a problem with this pillow, that is, the cushion provides the same elastic force to the user's head and cervical spine at the same time, resulting in excessive support force applied to the center of the head, causing the C-shaped curve of the cervical spine to be unable to be effectively formed, or in more serious cases, only the central part of the head is supported, thereby forming a gap between the cervical spine and the pillow. In addition, since the cushion is set on the entire surface of the pillow, its unit price is relatively increased.

The purpose of the present invention is to solve the above problems, and one of the purposes of the present invention is to configure the buffer for supporting the central part of the head and the buffer for supporting the cervical vertebra differently so that no gap is formed between the cervical vertebra and the surface of the pillow, thereby effectively supporting and supporting the cervical vertebra.

In addition, another purpose of the present invention is to provide a functional pillow that minimizes the use area of the cervical vertebra support cushioning component, thereby reducing the overall production cost, while maintaining the lifting effect of the cervical vertebra, so that the user can have a good sleep.

One embodiment of the present invention is to provide a functional pillow for supporting the cervical vertebra and helping to have a good sleep, comprising: a pillow body, including a central head area for positioning the user's head, a crown for positioning the top of the user's head, and a cervical vertebra support part for positioning the user's cervical vertebra; a pillowcase, covering the pillow body in a covering manner; and a first buffer member arranged on the cervical vertebra support part, which is made of a viscous material and has a plurality of through holes, and the pillow body is filled with a second buffer member composed of a plurality of round particles, and the width D2 of the cervical vertebra support is in the range of 110mm to 160mm in the front-to-back direction.

At this time, the first buffer member can be set to cover 50% or more of the left-right length L of the pillow body.

Additionally, the first buffer may include a mixture including a copolymer of a polystyrene-based polymer and polypropylene and an oil.

Meanwhile, the second buffer member may include an elastic body, and the elastic body may be one of a styrene-based polymer, a polyurethane-based polymer and an ester-based polymer.

In addition, the pillowcase may include: an outer pillow cover for covering the entire outer surface of the pillow body; and a cushioning support cover, which is disposed in the outer pillow cover and sewn to the outer pillow cover in the form of supporting the lower portion of the first cushioning member.

One embodiment of the present invention may further include a blocking layer, the upper and lower portions of which are sewn to the outer pillow cover and at least partially block the second buffer member from moving between the central head area and the cervical vertebra support portion.

According to the disclosure of the present invention, since the first buffer supporting the cervical vertebra is set as a single body made of a viscous material, and the second buffer supporting the central area of the head is set as a polymer composed of a plurality of round particles, the cervical vertebra support part can effectively support the cervical vertebra by the elasticity of the first buffer, and on the contrary, the second buffer moves in all directions due to the weight of the head, so that the central area of the head is naturally pressed down. Therefore, an ideal C-shaped curve is formed from the head lowering and the cervical vertebra lifting, so that there is no gap between the cervical vertebra and the pillow surface, which can help the user get a good sleep.

In addition, according to the disclosure of the present invention, since the first buffer manufactured by injection molding is limited to use in the cervical vertebra support part, the overall production cost of the functional pillow can be reduced.

The effects disclosed by the present invention are not limited to those described above. Other effects not described in this article will be understood by those with ordinary technical knowledge in this field through the following description.

FIG. 2 is a three-dimensional diagram of the first buffer of the functional pillow of FIG. 1, which is decomposed and explained. FIG. 3 is a cross-sectional view of FIG. 1 along the A-A' section line. FIG. 4 is an enlarged view of part B of FIG. 3.

Referring to FIGS. 1 to 7 , a functional pillow 100 provided by the present invention may include a pillow body 110, a pillowcase 120, and a first buffer 140.

The pillow body 110 may include a cervical vertebra support portion 111, a head center area 112, and a crown portion 113. The cervical vertebra support portion 111 is located at the cervical vertebra position of the user relative to the lying state. The head center area 112 is located at the user's head position. The crown portion 113 is located at the top of the user's head. The cervical vertebra support portion 111, the head center area 112, and the crown portion 113 may be located on the surface area of the pillow body 110.

The cervical vertebra support portion 111 can extend backward in a convex curved shape from the front end of the pillow body 110 near the user's shoulder. Here, the front-to-back direction of the pillow body 110 is set as the direction for connecting the user's head and neck.

The head center area 112 is connected to the cervical vertebra support part 111 and can extend from the cervical vertebra support part 111 to the rear of the pillow body 110 in a convex curved shape, while the crown part 113 is connected to the rear end of the head center area 112 and extends to the rear end of the pillow body 110 in a convex curved shape.

The pillowcase 120 covers the pillow body 110 in a covering manner. The pillowcase 120 can further accommodate the first buffer 140 and the pillow body 110, which will be described later. The pillow body 110 can be filled with a second buffer 130, which is a polymer composed of a plurality of spherical particles. That is, the pillow body 110 described in the present invention can refer to a structure filled with the second buffer 130 and covered by the pillowcase 120.

The first buffer 140 can be set to cover a portion of the upper surface of the cervical vertebra support part 111. Specifically, the width of the first buffer 140 in the front-to-back direction can be the same as the width D2 of the cervical vertebra support part 111 in the front-to-back direction. The left-right longitudinal dimension of the first buffer 140 can be set to cover 50% or more of the left-right longitudinal dimension L2 of the cervical vertebra support part 111. (See Figure 6) At this time, the left-right longitudinal dimension of the cervical vertebra support part 111 is the same as the left-right longitudinal dimension of the pillow body 110.

The first buffer member 140 may be made of a viscous material and have a plurality of through-holes to keep the cervical spine in a C-shaped curve during sleep. The material and structure of the first buffer member 140 will be described later.

Unlike the second buffer 130 composed of a plurality of spherical particle aggregates, the first buffer 140 can be configured as a single body (single elastic body). Each particle of the second buffer 130 will form a diffusion effect within the area surrounded by the pillowcase 120 under the pressure of the user's head. On the contrary, since the first buffer 140 is a single elastic body, its movement is limited, and when the user presses the first buffer 140 with the cervical spine, it will exert an elastic force along the lifting direction of the user's cervical spine.

That is, referring to FIG. 7 , it can be seen from the use mode of a functional pillow 100 embodiment disclosed by the present invention that when a user lies on the pillow 100, his head naturally presses down along the curvature of the user's own head, so that the cervical spine is stably supported and lifted to form an ideal C-shaped curve.

The outer thickness of the first buffer member 140 can be formed uniformly. The first buffer member 140 can be disposed in a region of the pillow body 110 spaced apart from the second buffer member 130.

More specifically, the pillowcase 120 may include an outer pillow cover 121 and 122 covering the entire surface of the pillow body 110, and a cushioning support cover 123 disposed inside the outer pillow cover 121 and 122 and sewn on the outer pillow cover 121 and 122 in the form of supporting the lower portion of the first cushioning member 140. (See FIG. 3)

At this time, the outer pillow covers 121 and 122 are divided into an upper outer cover 121 covering the upper surface of the pillow body 110 and a lower outer cover 122 covering the lower surface of the pillow body 110, and the upper outer cover 121 and the lower outer cover 122 can be sewn together to form the outer pillow covers 121 and 122.

At the same time, the first buffer member 140 can be placed in a first internal space S1 formed by the sewn upper outer cover 121 and the buffer support sleeve 123, and the second buffer member 130 can be filled in a second internal space S2 and a third internal space S3 in addition to the first internal space S1. That is, the first buffer member 140 and the second buffer member 130 can be respectively arranged in different areas.

This configuration can prevent the second buffer member 130 from being stuck in the through hole of the first buffer member 140.

In addition, with this configuration, the periphery of the first buffer member 140 is covered by the upper outer cover 121 and the buffer support sleeve 123, so even if the user turns over during sleep, the excessive flow and diffusion of the first buffer member 140 can be prevented.

In addition, with this configuration, since no adhesive or the like that can limit the movement of the first buffer member 140 is used, even if the user breathes facing the pillow body 110 during sleep, it will not cause harm to the user's health.

On the other hand, the linear length of the cervical spine of general adult males and females is 107.5 mm. Therefore, when the user lies his/her shoulders on the front end of the pillow 100, the width D2 of the cervical spine support portion 111 in the front-to-back direction is formed to be between about 110 mm and 160 mm.

Therefore, when the total width D1 of the pillow body 110 of a general pillow 100 in the front-to-back direction is 450 mm, relative to D1 being the total width of the pillow body 110 in the front-to-back direction, the width D2 of the cervical vertebra supporting portion 111 in the front-to-back direction is formed to be approximately between 24% and 35%.

In addition, in one embodiment of the present invention, the cervical vertebra support portion 111, the head center area 112 and the crown 113 can be located in three areas respectively, provided that the three areas are divided into three parts by dividing the pillow body 110. That is to say, when the width D1 of the pillow body 110 is 450mm, the cervical vertebra support portion 111 can be arranged at a position 150mm away from the front end of the pillow body 110, the head center area 112 can be located at a position 150mm to 300mm away from the front end of the pillow body 110, and the crown 113 is located at a position 300mm to 450mm away from the front end of the pillow body 110.

A first imaginary boundary line a1 connecting the cervical vertebra support portion 111 and the central area 112 of the head can be set. Similarly, a second imaginary boundary line a2 connecting the cervical vertebra support portion 111 and the crown portion 113 can be set (refer to Figures 1 and 3).

At this time, the pillow body 110 may have a recessed portion 115 formed along the second imaginary sideline a2 or overlapping with the second imaginary sideline a2. The recessed portion 115 may be disposed at the center of the pillow body 110 in the left-right longitudinal direction.

The shape of the recessed portion 115 is a long rectangle or a long ellipse in the left-right longitudinal direction, and can be formed by sewing the upper and lower surfaces of the pillowcase 120 along the circumference of the above shape. Therefore, an area is formed around the inner circumference of the recessed portion 115 into which the second buffer member 130 may not enter.

This allows the second buffer member 130 to spread in the left or right direction of the central area 112 of the head when the user lies on the pillow 100. In other words, the recessed portion 115 has the effect of partially blocking the second buffer member 130 from moving backward (toward the crown 113) and preventing the central area 112 of the head from being excessively pressed downward.

The pillow 100 according to the embodiment of the present invention may further include a blocking layer 150, the upper and lower parts of which are sewn to the outer pillow covers 121 and 122, and at least partially block the second buffer member 130 from moving between the head central area 112 and the cervical vertebra support portion 111 (see FIG. 3).

The upper and lower portions of the barrier layer 150 may be sewn to the upper outer cover 121 and the lower outer cover 122, respectively. The barrier layer 150 may extend in the left and right longitudinal directions, but may not be sewn to the left and right ends of the pillowcase 120 and may be separated from them by a preset distance.

That is, the blocking layer 150 can prevent the second buffer member 130 existing in the central part of the pillow body 110 from moving from the second internal space S2, i.e., the lower space of the cervical vertebra support portion 111, to the third internal space S3, i.e., the lower space of the head central area 112.

In this way, when the user's cervical spine is pressed against the first buffer member 140, the second buffer member 130 disposed thereunder can be prevented from being pushed backward, so that the user's cervical spine can be effectively and stably supported.

On the other hand, when the movement of the second buffer 130 is 100% blocked, the height of the cervical vertebra support portion 111 may be too rigid. In contrast, the blocking layer 150 is not sewn to the left and right ends of the pillowcase 120, but is separated therefrom. Thus, the second buffer 130 can achieve partial movement.

The second buffer member 130 includes an elastic body, and the elastic body can be one of a styrene-based polymer, a polyurethane-based polymer, and an ester-based polymer. However, the material of the second buffer member 130 is not limited to the above materials, as long as the material is formed by a plurality of spherical particles and can eliminate plastic deformation.

The composition for making the first buffer may include a mixture of a copolymer of a polystyrene-based polymer and polypropylene and an oil. The polystyrene-based polymer has a triblock structure. The polystyrene-based polymer may be a styrene-(ethylene/butylene)-styrene (SEBS) block copolymer or a polystyrene-block-poly(ethylene-ethylene/propylene)-block polystyrene (SEEPS). Therefore, the copolymer obtained by copolymerizing a polystyrene polymer and polypropylene may be PP-SEBS.

The mixture may include 30 to 40 wt% of a copolymer formed by copolymerization of a polystyrene polymer and a polypropylene and 60 to 70 wt% of an oil. Here, when the oil content is less than 60 wt%, its hardness (Shore A) increases, so the effect of the dispersion pressure is reduced, and the shrinkage rate is so high that it is difficult to spray during injection. On the other hand, when its content is higher than 70 wt%, the oil and the copolymer are not easily mixed, so that it cannot be injected, and even if it is injected by force, it will cause oil spraying during use. For the above reasons, the oil content is preferably within the above range.

According to one embodiment of the present invention, the composition for manufacturing the first buffer may include 5 to 8 parts by weight of an additive of a mixture of oil and a copolymer obtained by copolymerizing a polystyrene-based polymer and polypropylene relative to 100 parts by weight.

At this time, when the content of the additive is less than 5 parts by weight, the oil and the copolymer cannot be mixed, so its properties may be reduced. On the other hand, when the content is higher than 8 parts by weight, the hardness increases. For the above reasons, the content of the additive is preferably within the above range. The main purpose of using additives is to eliminate the oil spraying phenomenon and improve the heat resistance of the gel pad. In addition, dry silica or wet silica can also be used as an additive.

When dry silica is used, it may be a fumed silica.

If necessary, the composition may further include a heat stabilizer to prevent degradation caused by heating during molding. In this case, 0.3 to 0.7 parts by weight of the heat stabilizer may be added relative to 100 parts by weight of the mixture consisting of the copolymer and the oil.

The thermal stabilizer can be an organic phosphite, such as triphenyl phosphite, triester-(2,6-dimethylphenyl) phosphite, triester-(mixed mono- and di-nonylphenyl) phosphite; phosphonates, such as dimethyl phenylphosphonate; phosphates, such as trimethyl phosphate; or a combination comprising at least one of the above thermal stabilizers.

The composition can be provided with aromatherapy and antibacterial functions by adding 0.5 to 5.0 parts by weight of essential oil and 0.05 to 10.0 parts by weight of antibacterial agent relative to 100 parts by weight of the mixture consisting of copolymer and oil.

When the content of essential oil is less than 0.5 parts by weight, it is difficult to obtain the aromatherapy effect. On the other hand, when the content is higher than 5.0 parts by weight, the properties of the composition may be reduced. The essential oil can be extracted from at least one of the combination of lavender, grapefruit, eucalyptus, rosemary, mint and ylang-ylang.

When the content of the antibacterial agent is less than 0.05 parts by weight, the antibacterial activity value is less than 2, making it difficult to exert the antibacterial effect. On the other hand, when the content of the antibacterial agent exceeds 10.0 parts by weight, problems such as the generation of bubbles, degradation of physical properties, inability to form or inability to measure may occur during the manufacturing process of the first buffer 140. The antibacterial agent can be an organic antibacterial agent or an inorganic antibacterial agent. The organic antibacterial agent can be bis(2-pyridinethiol-1-oxide).

Referring to FIG. 4 and FIG. 5 , the first buffer member 140 may include a lower buffer portion 141 and an upper buffer portion 142. The lower buffer portion 141 has a first through hole 141a, and each first through hole 141a is vertically penetrated upward and downward. Each first through hole 141a has a regular hexagonal cross section. The first through holes 141a are spaced apart from each other at regular distances by a first partition wall 141b and are arranged in the horizontal and vertical directions.

The upper buffer portion 142 may be formed above the lower buffer portion 141, and the upper buffer portion 142 may be integrally connected to the lower buffer portion 141. The upper buffer portion 142 may be provided with a second through hole 142a, each of which is vertically penetrated upward and downward, and the second through hole 142a has a regular hexagonal cross-section larger than the first through hole 141a. The second through holes 142a are spaced apart from each other at regular distances by a second partition wall 142b, and the thickness of the second partition wall 142b in the left-right direction is thinner than the thickness of the first partition wall 141b in the left-right direction, and are arranged in the horizontal and vertical directions.

The center of the first through hole 141a and the first partition wall 141b coincides with the center of the second through hole 142a and the second partition wall 142b.

Therefore, the first buffer member 140 has a double honeycomb structure due to the first and second through holes 141a and 142a, but is formed into a step shape due to the thickness difference between the first partition wall 141b and the second partition wall 142b.

A reinforcing rib 143 may be disposed inside the first through hole 141a and the second through hole 142a. The reinforcing rib 143 may be composed of a structure in which three straight ribs intersect and are connected at the center. The six ends of the reinforcing rib 143 may be connected to the six surfaces at the boundary between the first partition wall 141b and the second partition wall 142b. Therefore, the reinforcing rib 143 may improve the durability of the first buffer member 140 by supporting the first partition wall 141b and the second partition wall 142b in the horizontal direction.

Thus, since the first buffer 140 is made of the above structure and material, compared with a buffer generally made of a planar structure and polyurethane material, its maximum body pressure and temperature and humidity change rate are low and its sleep latency is shortened.

That is, in the first buffer 140, the first partition wall 141b of the lower buffer part 141 facing the pillow body 110 is configured to be relatively thick, so as to minimize deformation and provide stable support. As for the second partition wall 142b of the upper buffer part 142 facing the user's cervical vertebrae skin, it can be configured to be relatively thin to provide comfort.

The following will refer to Figure 8 to explain the changes in sleep quality caused by the different settings of the first buffer 140.

Figure 8 is a table showing the results of experiments related to sleep quality by changing the first buffer setting area.

The table showing the results in Figure 8 was made based on multiple sleep physiological function tests conducted on 20 subjects, and was made by collecting data from 4-channel EEG (electroencephalogram), 2-channel EOG (oculogram), single-channel ECG (electrocardiogram) and single-channel 1EMG (electromyogram).

The test results are then used to calculate the sleep latency, which represents the delay in falling asleep, user satisfaction, which represents the subjective perception of sleep quality (survey results collected after the test), and sleep efficiency (sleep time/time in bed*100).

The experiment for each subject was conducted in a laboratory with an average temperature of 22°C and an average relative humidity of 45%, and lasted for 8 hours from 10:00 pm to 06:00 am the next day.

Refer to the experimental results table in Figure 8. When the first buffer 140 is only set at the cervical vertebra support part 111, the user's satisfaction is the highest and the sleep efficiency is also the highest. The sleep latency in the above situation is 13.4 minutes, which is shorter than other situations.

In addition, when referring to the experimental result table of FIG8 , it can be found that the values of each result are negative numbers, because the first buffer 140 has been diffused to the entire area of the pillow body 110. That is, although the head must be pressed down and the cervical spine is lifted, the use area of the first buffer 140 is not limited to the cervical vertebra support part 111 but will be expanded, so the user's head will be lifted unnecessarily, causing the user to feel quite uncomfortable, thereby reducing sleep efficiency and increasing sleep latency.

As described above, the first buffer member disclosed in the present invention for supporting the cervical vertebra is a single body made of a viscous material, and the second buffer member for supporting the central area of the head is a polymer composed of a plurality of round particles. The cervical vertebra support portion can effectively support the cervical vertebra under the elastic force of the first buffer member, while the second buffer member moves in all directions due to the weight of the head, so that the central area of the head is naturally pressed down. Therefore, an ideal C-shaped curve is formed with the head lowered and the cervical vertebra lifted, and there is no gap between the cervical vertebra and the surface of the pillow, so as to achieve the effect of using the pillow to help the user have a deep sleep.

In addition, since the first buffer part manufactured by injection molding is only used in the cervical vertebra support part, the overall production cost of the functional pillow is reduced.

Although the above description illustrates the content of the present invention through limited embodiments and drawings, the content of the present invention is not limited to the exemplary embodiments. For ordinary technical personnel familiar with the field, it is obvious that the present invention can be modified and changed without departing from the spirit or scope of the present invention. Therefore, the patent scope of the present invention is limited only by the scope of the patent application, and all equal or equivalent modifications should be covered by the patent scope of the present invention.
