Referring to fig. 1 to 6, a functional pillow 100 according to an embodiment of the present invention includes a pillow body 110 and a first cushioning material 120.

The pillow body 110 is formed with a head support 111 and a cervical vertebrae support 112, which support the head and cervical vertebrae of a user, respectively, on the upper portion thereof with reference to the user lying down. The lower portion of the pillow body 110 may be flat.

The head support 111 may be formed in a curved shape with a middle portion recessed in the right and left directions. The head support 111 may be formed in a shape gradually raised from the head to the neck of the user. The head support 111 may be rounded along the upper side edge.

The cervical vertebrae supporting part 112 can maintain the cervical vertebrae in a C-shaped curve during sleep, and can allow a user to sleep soundly in a correct sleeping posture. The average length of the straight line of the cervical vertebrae of adult men and women is 107.5mm, and the cervical vertebrae supporting part 112 may be formed in a shape and size capable of maintaining the C-shaped curve of the cervical vertebrae at an angle of 20 degrees.

A cervical vertebrae support 112 may be formed to be elongated from the head support 111 to support the cervical vertebrae of the user. That is, the cervical vertebrae supporting part 112 may have a left and right width smaller than that of the head supporting part 111, and be formed to be elongated from the middle of the edge of the head supporting part 111 adjacent to the user's neck.

The cervical vertebrae supporting part 112 may be formed in a curved shape which is convex in a direction connecting the head and the neck of the user. The cervical vertebrae supporting part 112 may be rounded along the upper side edge. The cervical vertebrae support 112 and the head support 111 may be provided according to a shape and size reflecting the head and shoulder widths of average adults, men, and women.

According to one embodiment, the pillow body 110 may be comprised of a memory sponge. Memory sponge is a material that is used by the U.S. space agency to cushion the impact of astronauts when launching airships. The memory sponge has a rebound force which is slowly restored to the original shape when pressure is applied to the memory sponge, and the pillow body 110 can properly disperse the pressure of the head and the cervical vertebra through the whole memory sponge. According to another embodiment, the pillow body 110 may be formed of a latex material, and the pressure of the head and the cervical vertebrae is properly dispersed as a whole by the repulsive force of the latex.

The first buffer materials 120 are insertedly coupled at a predetermined interval in the left and right directions of the cervical vertebrae supporting part 112 at the upper part of the cervical vertebrae supporting part 112, respectively. The upper portion of the cervical vertebrae supporting part 112 has cervical vertebrae supporting part insertion grooves 112a for inserting the first cushioning materials 120 from the upper portion, respectively.

At this time, the bottom surface of the cervical vertebrae supporting portion insertion groove 112a is formed in a shape of supporting the first cushioning material 120 as a whole. The inner wall of the insertion groove 112a for the cervical vertebrae support part is formed in the same shape as the outer wall of the first buffer material 120 so that the first buffer material 120 is coupled to the insertion groove 112a for the cervical vertebrae support part by insertion. Thereby, the bottom and the outer wall of the first cushioning material 120 can be stably supported by the insertion groove 112a for the cervical vertebrae supporting part.

The first buffer material 120 is made of a viscoelastic material and has a plurality of through holes. That is, the first buffer material 120 has both viscosity and elasticity, and is constructed in a through-hole structure. Therefore, the first cushioning material 120 can disperse the pressure applied to the neck during sleep, and can provide optimal comfort without pressing the skin and blood vessels at a lower critical pressure. In addition, the first buffer material 120 can effectively dissipate body heat and sweat at the neck during sleeping through the air pump effect of the through hole structure and excellent ventilation, and maintain temperature and humidity, resulting in pleasant sleep.

Meanwhile, the first cushioning material 120 can supplement and perfect the cervical vertebrae supporting part 112 of the pillow body 110. That is, when the pillow body 110 is formed of memory sponge, the first cushion material 120 can supplement and improve the cervical vertebrae supporting part 112 of the pillow body 110, which emphasizes viscosity, to improve the supporting force and shape maintaining effect by inherent elasticity, thereby helping the cervical vertebrae to maintain the C-shaped curve all the time.

When the pillow body 110 is formed of latex, the first cushion material 120 can supplement and improve the cervical vertebrae supporting part 112 of the pillow body 110, which emphasizes viscosity, to reduce the contact area and pressure by inherent elasticity, reduce the irritation to the neck skin, and easily correspond to various body shapes.

The first buffer material 120 of the aforementioned structure is combined with the cervical vertebrae supporting part 112 in a physical manner, i.e., by insertion, not by adhesion, and thus can be deformed to support the cervical vertebrae of the user independently of the cervical vertebrae supporting part 112. Thereby, it is possible to provide a massage function according to the movement of the user in the sleep by giving the first cushioning material 120 a foreign body sensation different from that of the surrounding cervical vertebrae supporting part 112.

In order to improve the massage effect, the first buffer material 120 may protrude from the insertion groove 112a for the cervical vertebrae support part by 2mm to 8mm with reference to the maximum height of the cervical vertebrae support part 112. The lower the height of the first cushioning material 120 is, the smaller the massage effect is, and the higher the height of the first cushioning material 120 is, the higher the cushioning strength becomes, which may cause discomfort.

In addition, the first cushioning materials 120 may be arranged at intervals of 10mm to 20mm in order to improve the massage effect. Here, the interval of the first buffer materials 120 may be defined as the shortest distance between adjacent portions between the first buffer materials 120. If the interval between the first cushioning members 120 is too narrow or too wide, the degree of the foreign body sensation different from that of the peripheral cervical vertebrae supporting part 112 is reduced, and the massage effect is reduced.

Of course, according to another embodiment, the upper edge of the first buffer material 120 may be set to have the same height as the upper edge of the insertion groove 112a for the cervical vertebrae support, and the first buffer material 120 may be insertedly coupled to the insertion groove 112a for the cervical vertebrae support without a step. Meanwhile, the top of the first cushioning material 120 may be set to have the same height as the opening of the insertion groove 112a for the cervical vertebrae supporting part.

The first buffer material 120, which may be composed of 3 pieces, provides a buffering feeling by dispersing pressure to the middle and right and left sides of the cervical vertebrae. The left and right first cushions 120 may be symmetrical with respect to the middle first cushion 120, and the middle first cushion 120 may be disposed closer to the head support portion 111 than the left and right first cushions 120. Of course, the first cushioning material 120 may be composed of 2 or 4 or more.

For example, each of the first cushioning materials 120 may include lower and upper cushioning portions 121 and 122 and a reinforcing rib 123.

The lower buffer portion 121 is partitioned by a lower partition plate 121b so that lower through holes 121a are vertically penetrated with a regular hexagonal cross section, respectively. The lower through holes 121a may be arranged in a regular hexagonal shape.

The lower partition 121b may have a thickness that becomes thinner as it goes down. The upper end thickness of the lower partition 121b may be set to 1.65mm to 1.7mm, and the lower end thickness may be set to 1.55mm to 1.6 mm. Therefore, the lower through-hole 121a is gradually enlarged downward, and the molded lower cushion part 121 is easily taken out from the mold when the lower cushion part 121 is injection-molded. When the difference between the upper end thickness and the lower end thickness of the lower partition 121b is excessively large, the strength is weak.

The upper buffer part 122 is partitioned by an upper partition plate 122b so that upper through holes 122a are vertically penetrated in a regular hexagonal cross section. The upper side through holes 122a may be arranged in a regular hexagonal shape.

The thickness of the upper partition 122b may be thinner as it goes upward. The lower end thickness of the upper partition 122b may be set to 1.65mm to 1.7mm, and the upper end thickness may be set to about 1.5 mm. Therefore, the upper through hole 122a gradually expands upward, and the molded upper cushion part 122 is easily taken out from the mold when the upper cushion part 122 is injection molded. In addition, the upper spacer 122b reduces the contact area with the user's cervical vertebrae to reduce pressure since the upper end has a smaller thickness than the lower end. The upper separator 122b has a weak strength when the difference between the upper and lower thicknesses is too large.

The upper cushion part 122 is superimposed on the lower cushion part 121 such that the respective centers of the upper through holes 122a correspond to the respective centers of the lower through holes 121 a. The upper buffer part 122 and the lower buffer part 121 may be integrally formed. Therefore, the first buffer material 120 may have a 2-fold honeycomb (honeycomb) structure formed by the upper through holes 122a and the lower through holes 121a, and may more effectively disperse pressure while having air permeability.

The sizes of the upper side through-hole 122a and the lower side through-hole 121a are minimized within an allowable range of injection molding to maximize a pressure dispersion effect. For example, the shortest width of each of the upper through-holes 122a and the lower through-holes 121a may be set to 10mm to 12mm, and the greatest depth of each of the upper through-holes 122a and the lower through-holes 121a may be set to 12mm to 14 mm.

The reinforcing rib 123 is formed at each critical portion of the upper side through-hole 122a and the lower side through-hole 121 a. The reinforcing rib 123 may be formed at the critical periphery of the upper through-hole 122a connected with the lower through-hole 121a, together with molding at the time of injection molding of the upper cushioning portion 122. According to another embodiment, the reinforcing rib 123 may be formed at a critical periphery of the lower through-hole 121a connected with the upper through-hole 122a, together with molding when injection-molding the lower buffer portion 121.

The reinforcing rib 123 supports the upper side separator 122b and the lower side separator 121b in a horizontal direction to reinforce the first cushioning material 120. The reinforcing rib 123 may be constructed in a structure in which 3 in-line ribs are cross-connected at the center. The 6 ends of the reinforcing rib 123 may be connected to 6 corners located at the critical portions of the upper and lower separators 122b and 121b, respectively.

That is, 3 linear ribs of the reinforcing rib 123 are arranged in parallel in the horizontal direction on the upper separator 122b and the lower separator 121 b. Therefore, the reinforcing ribs 123 can enhance the supporting effect on the upper side separator 122b and the lower side separator 121b in the horizontal direction, increasing the durability of the first cushioning material 120. The width of each of the reinforcing ribs 123 may be set to be greater than the thickness of the upper and lower separators 122b and 121 b. The thickness of the reinforcing rib 123 may be set to 1.5 mm.

In addition, the composition of the viscoelastic material for preparing the first buffer material 120 may include a mixture of a copolymer of polystyrene polymer and polypropylene copolymer and oil. The polystyrene polymer is a triblock (triblock) structure. The Polystyrene polymer may be a styrene- (ethylene/butylene) -styrene Block Copolymer (SEBS), or a styrene-ethylene-propylene Block Copolymer (SEEPS). Thus, the copolymer of polystyrene polymer and polypropylene copolymer may be PP-SEBS.

The mixture may contain 30 to 40 wt% of a copolymer of a polystyrene polymer and a polypropylene copolymer, and 60 to 70 wt% of an oil. At this time, when the content of the oil is less than 60% by weight, the hardness (Shore A) increases, the effect of controlling dispersion decreases, the shrinkage ratio is large, and ejection (ejection) at the time of injection is difficult, and when it exceeds 70% by weight, the oil is not easily mixed with the co-polymer, injection is impossible, and even if injection is completed, oil injection occurs at the time of use, so the oil content should be set in the above range.

The composition may include 5 to 8 wt% of an additive based on 100 wt% of a mixture consisting of the copolymer and the oil. In this case, if the content of the additive is less than 5% by weight, the oil and the copolymer cannot be mixed and the physical properties are deteriorated, and if it exceeds 8% by weight, the hardness is increased, so that the additive should be added in the above-mentioned content range. The additive is used to remove oil spray and improve heat resistance, and dry silica or wet silica may be used. Fumed silica (FumedSilica) can be used as the dry silica.

The composition may further contain a heat stabilizer as necessary to prevent the composition from being heated by heating during molding. In this case, the composition may include 0.3 to 0.7 wt% of a heat stabilizer based on 100 wt% of a mixture composed of the copolymer and the oil.

The heat stabilizer may be composed of organic phosphites such as triphenyl phosphite, tris- (2, 6-dimethylphenyl) phosphorous acid, tris- (mixed mono-and di-nonylphenyl) phosphorous acid, or phosphonic acid esters such as dimethyl phenylphosphonate, or phosphoric acid esters such as trimethyl phosphate, or may be composed of a combination thereof.

The composition may include 0.5 to 5.0 wt% of aromatic oil and 0.05 to 10.0 wt% of antibacterial agent based on 100 wt% of a mixture consisting of the copolymer and the oil, and may have aromatherapy and antibacterial functions.

When the content of the aromatic oil is less than 0.5 wt%, the therapeutic effect cannot be achieved, and when the content is more than 5.0 wt%, the physical properties of the composition are reduced, the aromatic oil can be extracted from at least one selected from the group consisting of lavender, grapefruit, eucalyptus, rosemary, peppermint, and ylang-ylang (Y L ANG-Y L ANG).

If the content of the antibacterial agent is less than 0.05% by weight, the antibacterial activity value is less than 2, and the antibacterial effect cannot be exhibited, and if it is more than 10.0% by weight, there are problems that bubbles are generated during the production process, the physical properties are lowered, and the molding or metering cannot be performed. The antibacterial agent may be an organic antibacterial agent or an inorganic antibacterial agent. The organic antimicrobial agent may be Zinc pyrithione (Zinc bis: 2-pyridineethiol-1-oxide).

In addition, the functional pillow 100 may further include a second cushioning material 130. The second cushioning material 130 is insertedly coupled to an upper portion of the head support portion 111, and the upper portion of the head support portion 111 has a head support insertion groove 111a for inserting the second cushioning material 130 from the upper portion.

At this time, the bottom surface of the head support portion insertion groove 111a is formed in a shape in which the second cushioning material 130 is concavely bent left and right and the bottom portion of the second cushioning material 130 is entirely supported. The inner wall of the head support portion insertion groove 111a is formed in the same shape as the outer wall of the second cushioning material 130 to couple the second cushioning material 130 to the head support portion insertion groove 111a by insertion. Thereby, the bottom and the outer wall of the second cushioning material 130 can be stably supported by the head support portion insertion groove 111 a.

The upper edge of the second buffer material 130 may be set to have the same height as the upper edge of the head support insertion groove 111a, and the second buffer material 130 may be inserted and coupled to the head support insertion groove 111a without a step difference. Meanwhile, the top of the second cushioning material 130 may be set to have the same height as the opening of the head support insertion groove 111 a. According to another embodiment, the second cushioning material 130 may protrude from the head support insertion groove 111a at a height of 3mm to 5 mm.

As shown in fig. 7 and 8, the second cushioning material 130 is made of a viscoelastic material and has a plurality of through holes. That is, the second buffer material 130 has both viscosity and elasticity, and is constructed in a through-hole structure. Therefore, the second cushioning material 130 can disperse the pressure applied to the neck during sleep, and can provide optimal comfort without pressing the skin and the capillaries at a lower critical pressure. In addition, the second buffer material 130 can effectively dissipate body heat and sweat at the neck during sleeping through the air pump effect and excellent ventilation of the through hole structure, maintain temperature and humidity, and bring pleasant sleep.

Meanwhile, the second cushioning material 130 can supplement and complement the head supporting part 111 of the pillow body 110. That is, when the pillow body 110 is formed of the memory sponge, the second cushion material 130 can supplement and complement the head supporting part 111 of the pillow body 110 with enhanced stickiness, and improve the supporting force and the shape maintaining effect by inherent elasticity.

When the pillow body 110 is formed of latex, the second cushion material 130 can supplement and complement the head support part 111 of the pillow body 110, which emphasizes stickiness, to reduce a contact area and a pressure by inherent elasticity, thereby reducing irritation to the head skin.

The second cushioning material 130 may include lower and upper cushioning portions 131 and 132 and a reinforcing rib 133. The second buffer material 130 may have the same structure as the first buffer material 120 except for the overall size.

That is, the upper cushion part 132 and the lower cushion part 131 of the second cushion material 130 have the same cross-sectional structure of the through-hole as the upper cushion part 122 and the lower cushion part 121 of the first cushion material 120. The lower buffer 131 is partitioned by a lower partition 131b so that lower through holes 131a are vertically penetrated by a regular hexagonal cross section. The upper buffer portion 132 is partitioned by an upper partition 132b so that upper through holes 132a vertically penetrate each other with a regular hexagonal cross section.

The reinforcing ribs 133 of the second cushioning material 130 may have the same structure as the reinforcing ribs 123 of the first cushioning material 120. In addition, the second buffer material 130 may have the same material as the first buffer material 120.

As shown in fig. 9, the first and second cushioning materials 120 and 130 are received in the pillow case 140 in a state of being inserted into the insertion groove 112a for the cervical vertebrae supporting part and the insertion groove 111a for the head supporting part of the pillow body 110. The pillow cover 140 covers and protects the pillow body 110, the first cushioning material 120, and the second cushioning material 130 so that the first cushioning material 120 and the second cushioning material 130 are not separated from the insertion grooves 112a and 111a for the cervical vertebrae and the head support.

The pillow case 140 may have a zipper to facilitate the covering or the removal of the pillow body 110. The pillow case 140 may include an inner case and an outer case. The inner case may be formed of a fabric having water resistance and air permeability, such as an aqueous cleansing (aqua) fabric, etc., covering the pillow body 110, the first cushioning material 120, and the second cushioning material 130. Therefore, the inner case can prevent sweat and body fluid from directly contacting the pillow body 110, the first cushioning material 120, and the second cushioning material 130, and maintain ventilation, thereby providing comfort.

In order to maximize the air permeability of the outer sleeve, the left and right sides may be formed of mesh to cover the left and right sides of the inner sleeve. In addition, the outer cover may be formed of a fabric providing a warm feeling, such as a velour (velour) fabric, to cover portions other than the left and right side surfaces of the inner cover.

The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.
