Description

Functional pillow {Functional pillow}

The present invention relates to a pillow that hangs on the head when lying down for sleep or rest.

In general, humans sleep for about one-third of their lifespan, allowing physiological activities to ease one's fatigue and accumulate energy for the next day's activities.

To do this, it is necessary to secure enough sleep time, but it is very important to have a good night's sleep. Studies have shown that pillows play a very important role in helping you get a good night's sleep.

Pillows commonly used in homes are generally filled with a pillow-like cushioning material in a woven pillow cover and covered with a pillow cover on the outside, with the back of the head supported by the cushioning material. Allow them to sleep and relax.

On the other hand, the cervical spine of the neck effectively supports the weight of the head, and forms a C-shaped curve to relieve and distribute the impact force when walking or running. However, when the pillow of the above-described structure is used, the cervical spine cannot properly support the cervical spine during sleep, and thus, the cervical spine is not maintained in a C-curve state but is bent in reverse to be straightened to form a neck disc, a waist disc, or a stiff shoulder. This can be In addition, the nerves and blood vessels passing through the cervical spine are under pressure so that metabolism is not smoothly performed, so that a good night's sleep is not possible. In order to solve this problem, pillows of various structures have been proposed.

1 to 6, the functional pillow 100 according to an embodiment of the present invention includes a pillow body 110, and the cervical spine cushion member 120.

Pillow body 110 has a head support 111 and the cervical spine support 112 for supporting the user's head and cervical spine, respectively, on the basis of the user lying down. The pillow body 110 may have a flat bottom surface.

The head support 111 may be formed in a curved shape with the center portion concave to the left and right. The head support 111 may be formed in a form that increases from the head of the user toward the neck. The head support 111 may be rounded along the upper edge.

The cervical spine support 112 maintains the cervical spine in a C-shaped curve during sleep so that a good night's sleep can be taken. An average adult male and female cervical spine has a straight length of 107.5mm and an angle of 20 ㅀ, the cervical spine support 112 may be formed in a shape and size that can maintain the average adult male and female cervical spine in the form of a C-shaped curve.

Cervical support portion 112 may be formed extending from the head support 111 to support the cervical spine of the user. That is, the cervical spine support part 112 may have a left and right width smaller than the left and right widths of the head support part 111 and extend from the center of the edge of the head support part 111 close to the neck of the user.

The cervical spine support 112 may be formed in a convex curved shape along the direction connecting the head and neck of the user. Cervical support 112 can be rounded along the upper edge. The head support 111 and the cervical spine support 112 may be set in a shape and size reflecting the head and shoulder lengths of an average adult man and woman.

For example, the pillow body 110 may be formed of a memory foam. Memory Foam is a material developed by NASA to mitigate the impact of astronauts on spacecraft launches. Since the memory foam has a restoring force to gradually return to its original shape when pressed, the pillow body 110 may appropriately distribute the pressure of pressing the head and the cervical spine by the restoring force of the memory foam as a whole. As another example, the pillow body 110 is made of a latex material, it is possible to properly disperse the head and cervical pressing pressure by the restoring force of the latex as a whole.

Cervical cushion members 120 are fitted on the upper surface of the cervical spine support part 112 at predetermined intervals in the left and right directions of the cervical spine support part 112, respectively. Cervical support portion 112 may be provided with cervical support portion fitting grooves (112a) for fitting the cervical spine cushion members 120 from the top, respectively.

Here, the bottom of the cervical spine support groove (112a) may be formed in the form of supporting the lower portion of the cervical spine cushion member 120 as a whole. Cervical support portion fitting groove (112a) may be made in the same shape as the outer wall of the cervical spine cushion member 120, the inner wall of the cervical support portion fitting groove (112a) to fit the cushion member for cervical spine. Therefore, the lower and outer walls of the cervical cushion member 120 may be stably supported by the fitting groove 112a for the cervical support.

Cervical cushion members 120 are formed to have a plurality of through-holes of viscoelastic material. That is, the cervical spine cushion member 120 has both viscosity and elasticity, and consists of a through structure. Thus, the cervical spine cushion member 120 may provide optimal comfort by dispersing the pressure applied to the neck portion during sleep so as not to press the skin and the microvessel at a low critical pressure. In addition, the cervical spine cushion member 120 can effectively induce moisture and sweat through the air pumping effect and excellent breathability of the neck portion of the body heat and sweat during sleep to maintain a temperature and humidity, thereby inducing a comfortable sleep.

In addition, the cushion member 120 for the cervical spine allows to complement the cervical spine support 112 of the pillow body 110. That is, when the pillow body 110 is made of a memory foam, the cervical spine cushion member 120 complements the cervical spine support portion 112 of the pillow body 110, which has a viscous emphasis, thereby increasing the holding force and shape maintaining effect with inherent elasticity. This helps the cervical spine to maintain C-shaped curves at all times.

When the pillow body 110 is made of latex, the cervical spine cushion member 120 complements the cervical spine support portion 112 of the pillow body 110, which is emphasized elasticity, thereby reducing the contact area and reducing pressure by inherent viscosity, It reduces skin irritation at the site and makes it easy to cope with various body types.

Since the cervical cushion member 120 of the above-described structure is physically fitted without being bonded to the cervical support fitting groove 112a, the cervical spine support member 112 may be deformed independently to support the cervical spine of the user. Therefore, the cervical spine cushion members 120 may provide a heterogeneous feeling with the surrounding cervical spine support 112, thereby giving a massage function according to movement during sleep.

The cervical cushion members 120 may protrude from the cervical support fitting groove 112a at a height of 2 mm to 8 mm based on the maximum height of the cervical spine support 112 to increase the massage effect. The lower the protruding height of the cervical cushion member 120, the lower the massage effect, the higher the protruding height of the cervical cushion member 120, the higher the cushion strength can be inconvenient.

In addition, the cervical spine cushion member 120 may be arranged at intervals of 10mm ~ 20mm to increase the massage effect. Here, the interval between the cervical cushion members 120 may be defined as the shortest distance between adjacent portions of the cervical cushion members 120. If the spacing of the cervical cushion members 120 is too narrow or wide, the degree of imparting a sense of heterogeneity with the surrounding cervical spine support 112 may be lowered, thereby reducing the massage effect.

Of course, as another example, the upper edge of the cervical spine cushion member 120 is set to the same height as the upper edge of the cervical support fitting groove 112a, the cervical spine cushion member 120 is the cervical support fitting groove 112a. Can be fitted without stepping on. In addition, the upper portion of the cervical spine cushion member 120 may be set to the same height as the opening of the cervical support fitting groove 112a.

Cervical cushion member 120 is provided with three can provide a cushioning through pressure distribution to the center and left and right sides of the cervical spine. The left and right cushion members 120 are symmetrical with respect to the center cushion member 120, and the center cushion member 120 may be disposed closer to the head support 111 than the cushion members 120 on the left and right sides. have. Of course, the cervical spine cushion member 120 may be provided with two or four or more.

For example, each cervical cushion member 120 may include a lower cushion portion 121, an upper cushion portion 122, and reinforcing ribs 123.

The lower cushion part 121 is formed by being partitioned by the lower partition walls 121b such that the lower through holes 121a are vertically penetrated through the regular hexagonal cross section, respectively. The lower through holes 121a may be arranged in a hexagon.

The thickness of the lower partition wall 121b may be gradually thinned downward. The lower partition wall 121b may have a top thickness of 1.65 mm to 1.7 mm and a bottom thickness of approximately 1.55 mm to 1.6 mm. Therefore, the lower through-hole 121a is gradually expanded toward the lower side, thereby making it easier to take out the lower cushion portion 121 molded from the mold during injection molding of the lower cushion portion 121. The lower partition wall 121b may be weakened when the difference between the upper thickness and the lower thickness is too large.

The upper cushion part 122 is partitioned by the upper partitions 122b so that the upper through holes 122a are vertically penetrated through the regular hexagonal cross section, respectively. The upper through holes 122a may be arranged in a hexagon.

The thickness of the upper partition wall 122b may be gradually thinned upward. The upper partition wall 122b may have a lower thickness of 1.65 mm to 1.7 mm and an upper thickness of approximately 1.5 mm. Therefore, the upper through hole 122a is gradually expanded toward the upper portion, thereby making it easier to take out the upper cushion portion 122 molded from the mold during injection molding of the upper cushion portion 122. In addition, since the upper partition wall 122b has a thinner top thickness than the bottom thickness, the upper partition wall 122b may reduce the pressure in contact with the cervical spine of the user. The upper partition wall 122b may be weakened when the difference between the upper thickness and the lower thickness is too large.

The upper cushion part 122 is stacked on the lower cushion part 121 so that each center of the upper through holes 122a coincides with each center of the lower through holes 121a. The upper cushion part 122 may be integrally formed with the lower cushion part 121. Therefore, the cervical spine cushion member 120 may have a double honeycomb structure by the upper through holes 122a and the lower through holes 121a to have a breathability and to perform pressure distribution more effectively. .

The size of the upper through 122a and the lower through 121a is minimized in the range of injection molding, thereby maximizing the pressure dispersion effect. For example, the shortest widths of the upper through holes 122a and the lower through holes 121a may be set to 10 mm to 12 mm, and the maximum depths of the upper through holes 122 a and the lower through holes 121 a may be set to 12 mm to 14 mm. have.

The reinforcing ribs 123 are formed at the boundary portions of the upper through hole 122a and the lower through hole 121a. The reinforcing ribs 123 may be formed together at the time of injection molding of the upper cushion part 122, and thus may be formed around a boundary in the upper through hole 122a connected to the lower through hole 121a. As another example, the reinforcing ribs 123 may be formed together during the injection molding of the lower cushion part 121, so that the reinforcing ribs 123 may be formed around the boundary in the lower through hole 121a connected to the upper through hole 122a.

The reinforcing rib 123 supports the upper partition 122b and the lower partition 121b in a horizontal direction to reinforce the cervical spine cushion member 120. The reinforcing rib 123 may have a structure in which three straight ribs are connected to each other at the center. The six ends of the reinforcing rib 123 may be connected to six edges at the boundary of the upper partition 122b and the lower partition 121b, respectively.

That is, the reinforcing rib 123 has three straight ribs arranged horizontally side by side on the upper partition 122b and the lower partition 121b, respectively. Therefore, the reinforcing rib 123 may increase the durability of the cervical spine cushion member 120 by further increasing the effect of supporting the upper partition 122b and the lower partition 121b in the horizontal direction. Each rib width of the reinforcing rib 123 may be set to be larger than each thickness of the upper partition wall 122b and the lower partition wall 121b. The thickness of the reinforcing rib 123 may be set to 1.5 mm.

The composition of the viscoelastic material used in the manufacture of the cervical spine cushion member 120 may include a mixture of a polystyrene-based polymer and a copolymer of polypropylene and an oil. Polystyrene-based polymers have a triblock structure. The polystyrene-based polymer may be styrene- (ethylene / buthylene) -styrene block copolymer (SEBS) or polystyrene-block-poly (ethylene-ethylene / propylene) -block polystyrene (SEEEPS). Therefore, the copolymer copolymerized with the polystyrene-based polymer and polypropylene may be PP-SEBS.

The mixture may include 30 to 40% by weight of the copolymer copolymerized with the polystyrene-based polymer and polypropylene and 60 to 70% by weight of the oil. Here, when the oil content is less than 60% by weight, the hardness (Shore A) is increased, so that the effect of suppression dispersion is reduced and the shrinkage rate is very large, so that ejecting during injection is very difficult, and when it exceeds 70% by weight, the oil and copolymer Injection is not possible because it is not easy to mix, and even if it is injection, it is preferable to set the oil content in the above range because oil blooming occurs during use.

The composition may comprise 5 to 8 parts by weight of an additive based on 100 parts by weight of the mixture of the copolymer and the oil. In this case, when the content of the additive is used less than 5 weights, the oil and the copolymer may not be mixed, and thus the physical properties may be reduced. The additive is to remove oil blooming and to improve heat resistance, and dry silica or wet silica may be used. Fumed Silica may be used as the dry silica.

The composition may further comprise a heat stabilizer as necessary to prevent deterioration by heating during molding. Here, the composition may include 0.3 to 0.7 parts by weight of the heat stabilizer relative to 100 parts by weight of the mixture consisting of a copolymer and an oil.

The heat stabilizer consists of organic phosphites such as triphenyl phosphite, tris- (2,6-dimethylphenyl) phosphite, tris- (mixture of mono- and di-nonylphenyl) phosphites, or dimethylbenzene phosphonate It may consist of phosphonates such as, or of phosphates such as trimethyl phosphate, or a combination thereof.

The composition may have aromatherapy and antimicrobial functions, including 0.5 to 5.0 parts by weight of fragrance oil and 0.05 to 10.0 parts by weight of antimicrobial agent, relative to 100 parts by weight of the mixture of the copolymer and the oil.

When the content of the fragrance oil is less than 0.5 parts by weight, it is difficult to obtain the aromatherapy effect, and when it exceeds 5.0 parts by weight, the physical properties of the composition may be lowered. The fragrance oil may be extracted from at least one selected from the group consisting of lavender, grapefruit, eucalyptus, rosemary, peppermint and ylang-ylang.

If the content of the antimicrobial agent is less than 0.05 parts by weight, the antimicrobial activity value is less than 2, which makes it difficult to exert the antimicrobial effect. Can be. The antimicrobial agent may be an organic or inorganic antimicrobial agent. The organic antimicrobial agent may be zinc bis (2-pyridinethiol-1-oxide).

The head support fitting groove 111a may have the same inner wall as the outer wall of the head cushion member 130 so as to fit the head cushion member 130. Accordingly, the head cushion member 130 may be stably supported by the lower and outer walls of the head support fitting groove 111a.

Since the upper edge of the head cushion member 130 is set at the same height as the upper edge of the head support fitting groove 111a, the head cushion member 130 is fitted to the head support fitting groove 111a without step fitting. Can be. In addition, the upper portion of the head cushion member 130 may be set to the same height as the opening of the head support fitting groove 111a. As another example, the head cushion member 130 may protrude from the fitting groove 112a for the cervical spine at a height of 3 mm to 5 mm.

As illustrated in FIGS. 7 and 8, the head cushion member 130 is formed to have a plurality of through holes made of a viscoelastic material. That is, the head cushion member 130 has both viscous and elastic, and consists of a through structure. Accordingly, the head cushion member 130 may provide optimal comfort by dispersing the pressure applied to the scalp during sleep so as not to press the skin and the microvascular vessel at a low critical pressure. In addition, the head cushion member 130 can effectively induce moisture and sweat through the air pumping effect and excellent breathability of the perforated heat and sweat of the scalp during sleep to maintain a temperature and humidity, leading to a comfortable sleep.

In addition, the head cushion member 130 can complement the head support 111 of the pillow body 110. That is, when the pillow body 110 is made of a memory foam, the head cushion member 130 complements the head support portion 111 of the pillow body 110 with a viscous emphasis to increase the holding force and shape retention effect with inherent elasticity. Can be.

When the pillow body 110 is made of latex, the head cushion member 130 complements the head support portion 111 of the pillow body 110 with emphasis on elasticity, thereby reducing contact pressure and lowering pressure by inherent viscosity, thereby reducing scalp. To reduce skin irritation.

The head cushion member 130 may include a lower cushion portion 131, an upper cushion portion 132, and reinforcing ribs 133. Head cushion member 130 may be made of the same structure except for the overall size of the cervical spine cushion member 120.
