Description

Technical Field

[0001] This application relates to the field of everyday consumer goods, specifically to a memory foam pillow. Background Technology

[0002] As people's demands for sleep quality increase, more and more people are choosing to use memory foam pillows. However, in related technologies, memory foam pillows are usually made of a single piece of foam, with uniform material density and hardness. Therefore, the overall softness and hardness are consistent, which cannot adapt to the different cervical curvatures and softness and hardness needs of different people, and can easily lead to excessive local pressure or insufficient support. Utility Model Content

[0003] This application provides a memory foam pillow that offers users two options for support and height by forming two protrusions with different hardness, thus avoiding excessive local pressure or insufficient support.

[0004] The memory pillow provided in this application embodiment includes:

[0005] A slow rebound layer, the slow rebound layer including a first protrusion, a second protrusion and a recess disposed between the first protrusion and the second protrusion;

[0006] A breathable layer is disposed on the outer surface of the slow rebound layer;

[0007] A support layer, the hardness of which is greater than that of the slow rebound layer, is disposed inside the first protrusion or the second protrusion.

[0008] The memory foam pillow provided in this application adds a support layer to the middle of one of the first and second protrusions, thereby forming two first and second protrusions with different hardness, providing users with two options for support and height. This is beneficial for adapting to the cervical curvature and firmness needs of different people, and avoids excessive local pressure or insufficient support.

[0009] In some embodiments, the support layer is cylindrical.

[0010] In this way, the cylindrical support layer is easier to manufacture and process.

[0011] In some embodiments, the cylindrical support layer extends through the slow rebound layer and is disposed at the center of the first protrusion or the second protrusion.

[0012] Thus, the support layer is installed through the slow rebound layer, which facilitates the production and assembly of the support layer and the slow rebound layer.

[0013] In some embodiments, the top surfaces of both the first protrusion and the second protrusion are arc-shaped, and the support layer is disposed at the axis where the center of the top surface of the first protrusion or the second protrusion is located, and the axis of the support layer is collinear with the axis where the center of the top surface of the first protrusion or the second protrusion is located.

[0014] In this way, the coincidence of the axes allows the support layer to be located directly in the core area of ​​the protrusion, and the pressure is transmitted vertically to the support layer along the shortest path, which is conducive to accurately supporting the user's neck pressure.

[0015] In some embodiments, the first protrusion and the second protrusion have the same height.

[0016] In this way, the two sides are of equal height, allowing the memory foam pillow to be used on both sides without causing head bumps due to different heights.

[0017] In some embodiments, the height of the recess is 70% to 85% of the height of the first protrusion or the second protrusion.

[0018] In this way, it can avoid the indentation being too deep, which would cause the material to be over-compressed, and it can also avoid the indentation being too high, which would result in insufficient deformation.

[0019] In some embodiments, the top surface of the breathable layer is streamlined.

[0020] In this way, the streamlined shape can reduce the obstruction when turning over and avoid putting pressure on the ears.

[0021] In some embodiments, the slow rebound layer has a receiving cavity, and the support layer is disposed within the receiving cavity and adhesively bonded to the slow rebound layer.

[0022] In this way, the glue firmly bonds the two layers together, allowing the support layer to respond instantly to head pressure, providing more stable support and helping to prevent the support layer from shifting.

[0023] In some embodiments, the support layer is injection molded within the slow rebound layer.

[0024] Therefore, by placing the support layer injection molding inside the slow rebound layer, the risk of delamination can be eliminated, which helps to prevent the support layer from separating from the slow rebound layer.

[0025] In some embodiments, the breathable layer is adhesively bonded to the slow-rebound layer.

[0026] In this way, the adhesive bonding ensures that the breathable layer and the slow rebound layer are tightly bonded together, preventing delamination or displacement during use and maintaining the overall shape and support performance of the pillow.

[0037] As people's demands for sleep quality increase, more and more people are choosing to use memory foam pillows. However, in related technologies, memory foam pillows are usually made of a single piece of foam, with uniform material density and hardness. Therefore, the overall softness and hardness are consistent, which cannot adapt to the different cervical curvatures and softness and hardness needs of different people, and can easily lead to excessive local pressure or insufficient support.

[0038] Please see Figure 1 The memory foam pillow 100 provided in this application embodiment includes a slow rebound layer 10, a breathable layer 20, and a support layer 30. The slow rebound layer 10 includes a first protrusion 11, a second protrusion 12, and a recess 13 disposed between the first protrusion 11 and the second protrusion 12. The breathable layer 20 is disposed on the outer surface of the slow rebound layer 10. The hardness of the support layer 30 is greater than the hardness of the slow rebound layer 10, and the support layer 30 is disposed inside the first protrusion 11 or the second protrusion 12.

[0039] The memory foam pillow 100 provided in this application forms two protrusions 11 and 12 with different hardness by adding a support layer 30 to the middle of one of the first protrusions 11 and the second protrusion 12. This provides users with two options for support and height, which is beneficial for adapting to the cervical curvature and softness and hardness needs of different people and avoids excessive local pressure or insufficient support.

[0040] Please see Figure 1Specifically, in this embodiment, the top of the slow rebound layer 10 is U-shaped with high sides and low middle, and forms a first protrusion 11, a second protrusion 12 and a recess 13 disposed between the first protrusion 11 and the second protrusion 12. The first protrusion 11 and the second protrusion 12 are used to support the user's neck, and the recess 13 is used to support and wrap the user's head.

[0041] In this embodiment, the bottom surface of the slow rebound layer 10 is set as a plane so that the memory foam pillow 100 can be placed more stably.

[0042] In some embodiments, the top and bottom surfaces of the slow rebound layer 10 can be configured as curved surfaces that are high on both sides and low in the middle, so that the cross-section of the memory foam pillow 100 is figure-eight shaped. In this case, the memory foam pillow 100 can be used regardless of the front and back sides. It should be noted that since the recessed part 13 on the bottom side will be suspended, it will sink more during use compared to the memory foam pillow 100 with a flat bottom. Therefore, the recessed part 13 of the memory foam pillow 100 with a figure-eight cross-section should not be too soft or too thin. If the recessed part 13 is too soft or too thin, it will affect the support effect on the user's head.

[0043] In the embodiments of this application, the slow rebound layer 10 is typically made of a slow rebound material. Slow rebound material, also known as memory foam or inert foam, is a polyurethane polymer with an open-cell structure. Its core characteristic is that it combines viscosity and elasticity, allowing it to slowly deform under external force to adapt to pressure distribution and gradually return to its original shape after the external force is removed.

[0044] Optionally, the material of the slow rebound layer 10 can be polyurethane slow rebound sponge (memory sponge), silicone-based slow rebound material, gel slow rebound material, or composite slow rebound material. The specific material of the slow rebound layer 10 can be selected according to actual needs, which will not be elaborated here.

[0045] In some embodiments, in addition to slow rebound materials, the material of the slow rebound layer 10 can also be latex, silicone, or other materials. The specific material can be selected according to actual needs, and will not be elaborated on here.

[0046] While memory foam and other slow-rebound materials can conform to the head's curves and distribute pressure, their closed structure results in poor air circulation. Due to the high density of memory foam, it easily accumulates heat over time, affecting sleep quality. Long-term use may also lead to bacterial growth due to moisture buildup, compromising hygiene. In this embodiment, the memory foam pillow 100 further includes a breathable layer 20, which is attached to the top of the slow-rebound layer 10 along its surface and completely covers the top surface. Compared to the slow-rebound layer 10, the breathable layer 20 is more skin-friendly and wicks away sweat, thus preventing stuffiness and providing a better sleep experience.

[0047] Please see Figure 1 In some embodiments, the breathable layer 20 may also cover the entire outer surface of the slow rebound layer 10 to completely enclose the slow rebound layer 10.

[0048] It is important to note that the thickness of the breathable layer 20 needs to be considered when setting it. If it is too thick, it may affect the support, while if it is too thin, it may reduce the breathability.

[0049] In some embodiments, in order to further increase the air contact area of ​​the breathable layer 20 and improve the breathability, the breathable layer 20 may adopt a honeycomb / mesh design, for example, by forming breathable grooves through geometric cutting to enhance air circulation.

[0050] In some embodiments, in order to increase the air contact area of ​​the breathable layer 20, it is also possible to uniformly perforate the surface of the breathable layer 20 to form air convection channels.

[0051] In some embodiments, a temperature sensor or humidity sensor can be embedded inside the memory foam pillow 100 to detect the temperature and humidity at the point where the user contacts the memory foam pillow 100. By linking with a smart device to adjust the support firmness of the memory foam pillow 100 and the breathability of the breathable layer 20, the temperature and humidity at the point of contact between the user and the memory foam pillow 100 can be regulated, thereby further improving the user's sleep experience. Specifically, the temperature sensor or humidity sensor can be embedded within the breathable layer 20. In addition, a pressure sensor can also be embedded inside the memory foam pillow 100. This pressure sensor communicates with an app to transmit data, and the app performs data analysis to provide personalized support and sleep suggestions.

[0052] In this embodiment, the breathable layer 20 is a highly breathable silicone layer. Specifically, the breathable layer 20 is a silicone loofah mesh structure with more than 30,000 breathable pores, which helps to achieve the effects of rapid moisture absorption, strong breathability, and high moisture wicking of the breathable layer 20.

[0053] In some embodiments, the breathable layer 20 may also be made of 3D spacer fabric, mesh fabric, natural fibers (cotton, linen), high-density sponge, memory foam composite material, TPE material, down cotton, down, mulberry silk, hollow tube, latex, high-breathability slow rebound material, etc. The specific material of the breathable layer 20 can be selected according to the actual needs of the user, which will not be elaborated here.

[0054] Please see Figure 1 and Figure 2 In this embodiment, the memory foam pillow 100 also includes a support layer 30. The support layer 30 provides greater support for the slow rebound layer 10 and the breathable layer 20. Specifically, the support layer 30 is cylindrical, which facilitates manufacturing. The top surfaces of the first protrusion 11 and the second protrusion 12 are both arc-shaped. The support layer 30 is located at the axis where the center of the top surface of the first protrusion 11 or the second protrusion 12 is located, and the axis of the support layer 30 is collinear with the axis where the center of the top surface of the first protrusion 11 or the second protrusion 12 is located. For example, the support layer 30 is located at the axis where the center of the top surface of the first protrusion 11 or the second protrusion 12 is located. Within a protrusion 11, the support layer 30 is located at the axis of the center of the top surface of the first protrusion 11, and the axis of the support layer 30 is collinear with the axis of the center of the top surface of the first protrusion 11 or the second protrusion 12. That is, if a cross-section is made along the axis perpendicular to the support layer 30, the center of the arc of the top surface of the first protrusion 11 coincides with the center of the cross-section of the support layer 30. Thus, the coincidence of the axes allows the support layer 30 to be directly located in the core area of ​​the first protrusion 11 or the second protrusion 12, and the pressure is transmitted vertically to the support layer 30 along the shortest path, which is beneficial for accurately supporting the user's neck pressure.

[0055] Because the human head and neck are not completely straight but have a certain physiological curvature, in some embodiments, the support layer 30 can also be designed as a dumbbell shape, thicker at both ends and thinner in the middle. This makes the middle of the pillow less firm and lower in support, which can well accommodate the head, while the firmness gradually increases on both sides, which can conform to the curve of the neck and provide necessary support for the neck. In this way, when the user sleeps on their back, the head rests on the lower middle area, and the neck receives support from both sides; when sleeping on their side, the higher side can fill the gap between the shoulder and the pillow, preventing the neck from being unsupported and keeping the neck and spine in a straight line. This helps maintain the natural posture of the head and neck during sleep, avoids excessive forward or backward flexion of the neck, and thus reduces the burden on the neck muscles and ligaments.

[0056] In some embodiments, the support layer 30 may also be configured in other shapes, such as an elliptical cylinder or an elliptical sphere. The specific shape can be selected according to the user's actual needs, which will not be elaborated on here.

[0057] In this embodiment, the support layer 30 is an integral structure made of a single material. In some embodiments, the support layer 30 may also have a more complex structure. For example, the support layer 30 may be made of a slow rebound material on the outside and a mechanical structure may be added inside. The hardness of the support layer 30 may be adjusted by adjusting the mechanical structure to support the slow rebound structure on the outside of the support layer 30.

[0058] In some embodiments, a support layer 30 may be provided in both the first protrusion 11 and the second protrusion 12.

[0059] In some embodiments, the support layer 30 within the first protrusion 11 and the second protrusion 12 may have the same hardness, thus providing sufficient support for the user regardless of which side they sleep on.

[0060] In some embodiments, support layers 30 with different hardness can also be provided in the first protrusion 11 and the second protrusion 12, so as to adapt to the cervical curvature and softness and hardness requirements of different groups of people.

[0061] In this embodiment, the support layer 30 should be made of a slow rebound material with high hardness, and its hardness should be greater than that of the slow rebound layer 10 and the breathable layer 20.

[0062] In some embodiments, the material of the support layer 30 may also be latex or silicone. The specific material of the support layer 30 can be selected according to actual needs, and will not be elaborated further here.

[0063] In some embodiments, the first protrusion 11 and the second protrusion 12 have the same height.

[0064] In this way, the two sides are of equal height, making the memory foam pillow 100 suitable for sleeping on both sides without causing head bumps due to different heights.

[0065] Specifically, in this embodiment, the first protrusion 11 and the second protrusion 12 have the same height, and specifically, the first protrusion 11 and the second protrusion 12 have the same maximum distance from the ground in their main treatment direction. Since both sides have the same height, both sides can be used for sleeping. Furthermore, because the first protrusion 11 and the second protrusion 12 contain a support layer 30, the two sides have different hardness, which can meet the needs of more people.

[0066] In some embodiments, the first protrusion 11 and the second protrusion 12 may also be configured to have different heights, which is beneficial to adapt to the needs of different people's cervical curvature.

[0067] In some embodiments, the first protrusion 11 may be configured to have different heights along its length. Specifically, the first protrusion 11 may be configured to be a concave shape with a lower middle and higher ends, similar to the function of the dumbbell-shaped support layer 30. This configuration helps to maintain the natural posture of the head and neck during sleep, avoids excessive forward or backward flexion of the neck, and thus reduces the burden on the neck muscles and ligaments.

[0068] Please see Figure 1 and Figure 2 In some embodiments, the height of the recess 13 is 70% to 85% of the height of the first protrusion 11 or the second protrusion 12.

[0069] In this way, it can avoid the indentation being too deep, which would cause the material to be over-compressed, and it can also avoid the indentation being too high, which would result in insufficient deformation.

[0070] Specifically, the cervical spine needs to maintain a forward curvature of 5° to 10° when sleeping on one's back. If the concave portion 13 is too low (e.g., below 70%), the cervical spine will over-arch backward due to lack of support, leading to increased pressure on the intervertebral discs; if it is too high (e.g., above 85%), it will compress the anterior cervical spine tissues. A 70% to 85% drop design can form a support surface that matches the curvature of the cervical spine, avoiding "suspension" or "excessive bending". When sleeping on one's side, the shoulder width determines the required support height. The height of the protrusion in the side-sleeping area needs to be equal to the shoulder width, while the concave portion 13 maintains 70% to 85% of the main support area, which can both fill the gap between the shoulder and the pillow and prevent the neck from twisting laterally due to excessive height difference. Therefore, in the embodiments of this application, the height of the concave portion 13 is 70% to 85% of the height of the first protrusion 11 or the second protrusion 12.

[0071] In some embodiments, in addition to the recessed portion 13, the dimensions of the breathable layer 20, the slow rebound layer 10, and the support layer 30 are also proportional to each other, so as to provide users with a more comfortable sleep experience while ensuring support.

[0072] In some embodiments, taking a memory foam pillow 100 with a length of 60cm and a width of 42cm and a support layer 30 provided in the first protrusion 11 as an example, the total height (maximum height) of the first protrusion 11 can be set to 8cm. At this time, the thickness (or minimum thickness) of the recess 13 is 5.5cm, the thickness of the breathable layer 20 can be set to 1.5cm, the diameter of the support part is 4.5cm, the thickness of the slow rebound layer 10 on one side of the first protrusion 11 is 2cm, and the thickness of the slow rebound layer 10 on one side of the second protrusion 12 is 6.5cm.

[0073] In some embodiments, the total height (maximum height) of the location of the first protrusion 11 can also be set to 10cm. In this case, the thickness (or minimum thickness) of the location of the recess 13 is 7cm, the thickness of the breathable layer 20 can be set to 2cm, the diameter of the support is 6cm, the thickness of the slow rebound layer 10 on one side of the first protrusion 11 is 2cm, and the thickness of the slow rebound layer 10 on one side of the second protrusion 12 is 8cm.

[0074] In some embodiments, the total height (maximum height) of the location of the first protrusion 11 can also be set to 12cm. In this case, the thickness (or minimum thickness) of the location of the recess 13 is 8.5cm, the thickness of the breathable layer 20 can be set to 2.5cm, the diameter of the support is 6.5cm, the thickness of the slow rebound layer 10 on one side of the first protrusion 11 is 3cm, and the thickness of the slow rebound layer 10 on one side of the second protrusion 12 is 9.5cm.

[0075] Please see Figure 1 In some embodiments, the top surface of the breathable layer 20 is streamlined.

[0076] In this way, the streamlined shape can reduce the obstruction when turning over and avoid putting pressure on the ears.

[0077] Specifically, in the embodiments of this application, the connection between the first protrusion 11, the recess 13 and the second protrusion 12 should be smooth, so that when the breathable layer 20 is attached to the top surface of the slow rebound layer 10, the top surface of the memory pillow 100 can be smoothly streamlined, which is beneficial to improving the user's sleep experience.

[0078] In some embodiments, the slow rebound layer 10 is provided with a receiving cavity 14, and the support layer 30 is disposed in the receiving cavity 14 and is adhesively connected to the slow rebound layer 10.

[0079] In this way, the glue firmly bonds the two layers together, and the support layer 30 can instantly respond to the pressure of the head, providing more stable support and also helping to prevent the support layer 30 from shifting.

[0080] Specifically, in this embodiment, the cylindrical support layer 30 penetrates the slow rebound layer 10 and is disposed in the middle of the first protrusion 11 or the second protrusion 12. That is, the receiving cavity 14 is cylindrical, and when the support layer 30 is disposed in the receiving cavity 14, the end face of the support layer 30 can be seen to protrude from the slow rebound layer 10 when viewed from both ends along the length direction of the memory pillow 100. In this way, the support layer 30 is disposed through the slow rebound layer 10, which facilitates the production and assembly of the support layer 30 and the slow rebound layer 10.

[0081] In this embodiment, both end faces of the slow rebound layer 10 along the length of the memory foam pillow 100 are planar. Similarly, both end faces of the breathable layer 20 and the support layer 30 along the length of the memory foam pillow 100 are planar. The end faces of the slow rebound layer 10, the breathable layer 20, and the support layer 30 along the length of the memory foam pillow 100 and located on the same side of the memory foam pillow 100 are coplanar. This coplanar design allows each layer of material to form a smooth transition at the end faces, avoiding changes in the pillow's shape due to misalignment or deformation between layers. For example, when a user's head rests against the pillow, the force can be evenly distributed across the layers, preventing localized collapse and extending the pillow's lifespan. Furthermore, during the production process, the coplanar design simplifies cutting, sewing, and other processes, reducing production difficulty and costs, and improving production efficiency. It also facilitates quality inspection and control.

[0082] It is important to note that the coplanar design requires reinforcement of the coplanar edges, such as by using edge binding or locking techniques, to prevent edge wear or fraying after long-term use, which could affect the pillow's structure and lifespan.

[0083] In some embodiments, the slow rebound layer 10 may completely enclose the support layer 30 within the slow rebound layer 10. In this way, the slow rebound layer 10 can provide a certain degree of protection for the internal support layer 30.

[0084] In this embodiment, the support layer 30 and the slow rebound layer 10 are connected by adhesive. For example, the adhesive connection between the support layer 30 and the slow rebound layer 10 can be achieved by pasting double-sided tape or injecting adhesive.

[0085] In some embodiments, the connection between the slow rebound layer 10 and the support layer 30 can also be a sewing connection, a snap-fit ​​connection, or the like. The specific connection method between the slow rebound layer 10 and the support layer 30 can be selected according to actual needs, and will not be elaborated further here.

[0086] In some embodiments, the support layer 30 is injection molded within the slow rebound layer 10.

[0087] Thus, by injection molding the support layer 30 within the slow rebound layer 10, the risk of delamination can be eliminated, which helps to prevent the support layer 30 from separating from the slow rebound layer 10.

[0088] Specifically, in this embodiment, the support layer 30 can be injection molded first, and then the support layer 30 can be placed in a mold for injection molding the slow rebound layer 10, and the slow rebound layer 10 outside the support layer 30 can be formed by secondary injection molding.

[0089] It should be noted that when the support layer 30 is injection molded into the slow rebound layer 10, the support layer 30 and the slow rebound layer 10 are non-removable. In order to make the memory pillow 100 have a longer service life, the non-removable support layer 30 should be made of a material with a relatively long service life.

[0090] In some embodiments, the support layer 30 can also be detachably connected to the slow rebound layer 10, that is, the support layer 30 is made replaceable. In this way, if the support layer 30 is damaged, such as insufficient support or severe deformation, only the support layer 30 can be supported without replacing the entire memory pillow 100, which helps to reduce maintenance costs.

[0091] In some embodiments, when the support layer 30 can be detachably connected to the slow rebound layer 10, multiple support layers 30 can be configured, and the multiple support layers 30 can have a variety of different hardness or shape, so that more sleep needs of users can be met by replacing the support layer 30.

[0092] In some embodiments, the breathable layer 20 is adhesively bonded to the slow rebound layer 10.

[0093] In this way, the adhesive bonding ensures that the breathable layer 20 and the slow rebound layer 10 are tightly bonded together, preventing delamination or displacement during use and maintaining the overall shape and support performance of the pillow.

[0094] Specifically, in the embodiments of this application, the breathable layer 20 and the slow rebound layer 10 can be connected by adhesive. For example, the breathable layer 20 and the slow rebound layer 10 can be connected by applying double-sided tape or injecting adhesives such as glue between them.

[0095] In some embodiments, the connection between the breathable layer 20 and the support layer 30 can also be a sewn connection, a snap-fit ​​connection, or the like. The specific connection method between the breathable layer 20 and the support layer 30 can be selected according to actual needs, and will not be elaborated further here.

[0096] In some embodiments, the 40% indentation hardness of the breathable layer 20 is 4 kPa to 5 kPa.

[0097] Thus, the breathable layer 20 has a moderate hardness range, neither too hard to make users feel uncomfortable, nor too soft to lack support.

[0098] Specifically, 40% indentation hardness refers to the pressure required to compress a material to 40% of its original thickness, usually measured in kilopascals (kPa). For example, if the 40% indentation hardness of a memory foam pillow 100 is 4 kPa, it means that 4 kPa of pressure needs to be applied to compress it to 60% of its thickness. To make the data more intuitive, it is usually replaced by the force required to compress the material to 40% of its original thickness over a test area. That is, the test area is 100 cm².2 At that time, the 40% indentation hardness of the breathable layer 20 is 40N~50N.

[0099] In this embodiment of the application, the test area is 100cm². 2 At that time, the 40% indentation hardness of the breathable layer 20 was 45N.

[0100] In some embodiments, the 40% indentation hardness of the slow rebound layer 10 is 5.5 kPa to 6.5 kPa.

[0101] Thus, the moderate firmness of the slow rebound layer 10 allows it to adapt to users of different weights and sleeping positions, and provides sufficient support.

[0102] Specifically, the test area is 100cm². 2 At that time, the 40% indentation hardness of the slow rebound layer 10 was 55N to 65N. In the embodiment of this application, the test area was 100cm². 2 At that time, the 40% indentation hardness of the slow rebound layer 10 was 60N.

[0103] In some embodiments, the 40% indentation hardness of the support layer 30 is 14 kPa to 15 kPa.

[0104] Thus, the strong support of the support layer 30 helps maintain the body's natural curves and prevents the body from sinking or deforming due to insufficient support.

[0105] Specifically, the test area is 100cm². 2 At that time, the 40% indentation hardness of the support layer 30 was 140N to 150N. In the embodiment of this application, the test area was 100cm². 2 At that time, the 40% indentation hardness of the support layer 30 was 145N.
