Description

Technical Field

[0001] The present application relates to the technical field of bedding, and in particular to a double-layer composite pillow. Background Art

[0002] As living standards continue to improve, people's expectations for sleep quality are also increasing. High-quality sleep not only relieves fatigue but also effectively improves physical and mental health. However, existing pillows on the market often lack support for different sleeping positions. This is particularly true for side sleepers, as traditional pillows fail to provide adequate support and comfort, seriously impacting sleep quality and well-being.

[0003] To address this issue, various approaches are commonly used in the prior art to improve pillow design. For example, some pillows employ multi-layer structures, using different filling materials to achieve varying degrees of support and softness. Others modify the shape of the pillow, such as wavy or U-shaped designs, to better adapt to the body's curves. Furthermore, some pillows use specialized filling materials, such as memory foam and down, to enhance comfort and durability. While these approaches have improved pillow performance to some extent, they still have many shortcomings.

[0004] Although these methods in the existing technology can solve the sleeping problems of side sleepers to a certain extent, they still have obvious defects. The first is insufficient support. Traditional pillows can hardly provide sufficient support, especially when sleeping on the side. The natural curves of the head and neck are not effectively supported, resulting in increased pressure on the cervical spine and affecting sleep quality. Secondly, the fillings of traditional pillows are single and prone to displacement or deformation after long-term use, which reduces the support and comfort of the pillow. Finally, existing pillow designs often lack consideration for individual differences and cannot fully fit each person's body shape and sleeping habits, resulting in discomfort during sleep. The existence of these problems has prompted researchers to continuously explore new solutions in order to provide users with a more scientific and comfortable sleeping experience. Summary of the Invention

[0005] In order to solve the problem that existing pillow designs often lack consideration for individual differences and cannot fully fit each person's body shape and sleeping habits, resulting in discomfort during sleep, the present application provides a double-layer composite pillow.

[0006] A double-layer composite pillow provided in the present application adopts the following technical solution: a double-layer composite pillow, comprising an upper main body and a lower main body, wherein the upper main body and the lower main body are connected in the middle, and the interiors of the upper main body and the lower main body are filled with different materials, the interior of the upper main body is filled with a first filling material to improve softness, and the interior of the lower main body is filled with a second filling material to improve support.

[0007] By adopting the above-mentioned technical solution, the double-layer composite pillow realizes the combination of a hard support layer and a soft wrapping layer through the double-layer structure design of the upper body and the lower body. The first filling material filled inside the upper body improves the softness of the pillow and enhances the user's comfort; the second filling material filled inside the lower body enhances the support of the pillow, effectively supports the head and neck, and prevents excessive sinking. This design not only solves the problem of insufficient support of traditional pillows, but also provides a better wrapping feeling and support effect through the reasonable combination of the upper and lower materials, significantly improving the user's sleep quality and comfort.

[0008] Optionally, the upper body and the lower body are made by sewing the pillowcase in one piece.

[0009] By adopting the above technical solution, the double-layer composite pillow is made by sewing the pillowcase in one piece, thereby ensuring the integrity and durability of the pillow.

[0010] Optionally, the upper body is divided into a first body, a second body and a third body by two dividing seams in the middle, the bottom of the second body is connected to the lower body, and the first body and the third body are separated from the lower body.

[0011] By adopting the above technical solution, the upper body is divided into three bodies by two dividing seams in the middle. The bottom of the second body is connected to the lower body, while the first body and the third body are separated from the lower body. The split design enables the pillow to better adapt to the natural curves of the head and neck, reduce cervical pressure, and improve sleeping comfort.

[0012] Optionally, the first body and the third body have a greater internal filling volume than the second body, so that the first body and the third body are tilted upward to form a butterfly shape.

[0013] By adopting the above technical solution, the internal filling volume of the first and third bodies is greater than that of the second body, so that the first and third bodies are tilted upward in a butterfly shape. This design effectively increases the support strength on both sides of the pillow and reduces the pressure on the shoulders when sleeping on the side. At the same time, the lower central part design allows the head to sink more naturally to the appropriate position, avoiding excessive bending of the cervical spine, and improving overall comfort and support. In addition, the butterfly design also increases the aesthetics of the pillow, which meets the aesthetic needs of modern homes.

[0014] Optionally, the middle of the second body is divided into a central area and two side areas by a middle seam, and the height of the central area is lower than that of the two side areas.

[0015] By adopting the above technical solution, the design of the center area being lower than the two side areas effectively reduces the pressure on the cervical spine when sleeping on the side and improves sleeping comfort. Specifically, the lower height of the center area allows the head to sink more naturally to the appropriate position, avoiding unnecessary bending of the cervical spine, thereby reducing the pressure on the cervical spine. At the same time, the lower center area can also reduce pressure on the ears and reduce the occurrence of ear pressure discomfort. In addition, this design helps to maintain good alignment of the spine, promotes blood circulation, and further improves sleep quality.

[0016] Optionally, the interior of the upper body is filled with a first filling material, and the first filling material is white goose down.

[0017] By adopting the above technical solution, the upper main body is filled with white goose down as the first filling material, which can significantly improve the softness and comfort of the pillow. White goose down has excellent fluffiness and warmth retention, and can provide a gentle wrapping feeling for the head, effectively relieving head pressure and improving sleep quality. At the same time, the white goose down material has good resilience and breathability, and can maintain the shape and comfort of the pillow during long-term use, avoiding a decrease in support due to displacement or compression of the filling.

[0018] Optionally, the interior of the lower body is filled with a second filling material, and the second filling material is natural latex particles.

[0019] By employing this technical solution, this functional side-sleeping composite pillow provides excellent support and breathability through the natural latex particles filling the lower body. These particles, with their excellent elastic recovery and durability, effectively support the head and neck, preventing deformation after prolonged use. This ensures proper spinal alignment when sleeping on your side, reduces cervical pressure, and improves sleep quality. Furthermore, the natural latex particles are antibacterial and anti-mite, contributing to a more hygienic sleeping environment.

[0020] Optionally, the interior of the lower body is filled with a second filling material, and the second filling material is a mixture of PE medium-bullet tubes and PE hard tubes with diameters of mm and mm respectively.

[0021] By adopting the above-mentioned technical solution, the lower body of the side sleeping pillow adopts a mixed filling of PE mid-bullet tubes and PE hard tubes with diameters of 7 mm and 10 mm respectively. This unique filling solution not only provides stronger support, but also maintains the appropriate pillow height. Specifically, the mixed filling of PE mid-bullet tubes and PE hard tubes can effectively support the head and neck of male users with wider shoulders when sleeping on their side, preventing excessive sinking, thereby reducing cervical spine pressure. In addition, this filling material also has good stability and durability, and is not easy to deform even after long-term use, ensuring that the pillow always maintains a good support effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The double-layer composite structure design combines a hard support layer with a soft wrapping layer to achieve different hardness and support effects. The one-piece sewing process ensures the integrity and durability of the pillow, improves the lifespan and stability of the pillow, and solves the problem of insufficient support of traditional pillows.

[0024] 2. The butterfly-wing design has a lower center and higher sides, which can better adapt to the natural curve of the head and neck when sleeping on the side, reducing pressure on the cervical spine and shoulders when sleeping on the side, improving overall comfort, while reducing ear pressure discomfort, improving blood circulation, promoting spinal alignment, and enhancing sleep quality;

[0025] 3. The gender-differentiated filling solution is specially designed based on the differences in body structure between men and women. Different filling partitions and weight solutions are adopted to meet the specific needs of different users. Regardless of the size of the head or the width of the shoulders, they can find the support that best suits them, thereby enhancing the user's personalized sleeping experience.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this application without substantially changing the technical content.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] Example 1:

[0034] Reference Figure 1 The double-layer composite pillow provided in the embodiment of the present application includes an upper main body 1 and a lower main body 2, wherein the upper main body 1 and the lower main body 2 are connected in the middle, and the upper main body 1 and the lower main body 2 are filled with different materials. The upper main body 1 is filled with a first filling material to improve softness, and the lower main body 2 is filled with a second filling material to improve support, thereby achieving the effect of providing personalized support and comfort through a double-layer structure.

[0035] Reference Figure 2 Specifically, the upper body 1 comprises a first body 11, a second body 12, and a third body 13. The first and third bodies 11, 13 have greater internal filling than the second body 12, resulting in them tilting upwards and forming a butterfly shape. This design allows the pillow to better conform to the natural curves of the shoulders and head when sleeping on the side, reducing pressure on the cervical spine while providing a better fit.

[0036] The internal filling material of the first body 11 and the third body 13 can be made of white goose down or other high-loft filling materials, such as duck down or silk. These materials are extremely soft and comfortable, providing a good sense of envelopment, while also being breathable to prevent overheating of the head during sleep. The internal filling material of the second body 12 can be made of natural latex particles or other materials with good support, such as memory foam or polyurethane foam. These materials provide sufficient support to prevent deformation after prolonged use, maintaining the pillow's support and durability.

[0037] Reference Figure 3The middle of the second body 12 is divided by a central seam to form a central region 16 and two side regions. The central region 16 is lower than the side regions. This design allows the pillow to better adapt to the natural curves of the head and neck when sleeping on the side, reducing pressure on the cervical spine while providing a better sense of support. The internal filling material of the central region 16 can be a higher-density material, such as high-density sponge or natural latex, to provide better support. The internal filling material of the side regions can be a lower-density material, such as low-density sponge or white goose down, to provide better softness and a more comfortable feel.

[0038] The upper body 1 and lower body 2 are made by sewing the pillowcase together. This integrated sewing process not only ensures the pillow's integrity and durability, but also prevents deformation during use, maintaining its height and shape. The pillowcase can be made of a breathable material, such as cotton or linen, to enhance its breathability and comfort. Furthermore, a layer of anti-mite material can be applied to the inside of the pillowcase to prevent the breeding of dust mites and improve the pillow's hygiene.

[0039] Example 2:

[0040] This embodiment differs from the previous one in that the lower body 2 is filled with a mixture of 7mm and 10mm diameter PE medium-bullet and rigid tubes, while the upper body 1 is filled with 95% high-quality white goose down with an 800 fill power. This filling solution is particularly suitable for men, providing stronger support while maintaining an appropriate pillow height. It is particularly suitable for men with wider shoulders, ensuring optimal neck and head support when sleeping on their side.

[0041] Specifically, the internal filling material of the lower body 2 is a mixture of PE medium-bullet tubes and PE hard tubes with diameters of 7 mm and 10 mm respectively. This mixed filling solution provides multi-level support through pipe materials of different diameters. The 7 mm PE medium-bullet tube has good flexibility and elasticity, and can provide moderate support while maintaining good softness. The 10 mm PE hard tube has higher rigidity and support, and can provide stronger support to prevent the pillow from deforming after long-term use. The mixed filling solution of these two materials can provide multi-level support, allowing the pillow to better adapt to the natural curve of the head and neck when sleeping on the side, reducing pressure on the cervical spine, and providing a better wrapping feeling.

[0042] The internal filling material of the upper body 1 is made of high-quality white goose down with a fill power of 95% and 800. This filling material is extremely soft and comfortable, can provide a good wrapping feeling, and has a certain breathability to prevent the head from overheating during sleep. The internal filling volume of the first body 11 and the third body 13 is greater than that of the second body, so that the first body 11 and the third body 13 are tilted upward in a butterfly shape. This design allows the pillow to better adapt to the natural curves of the shoulders and head when sleeping on the side, reduce the pressure on the cervical spine, and provide a better wrapping feeling. The middle of the second body 12 is divided by a middle seam to form a central area 16 and two side areas, and the height of the central area 16 is lower than the two side areas. This design allows the pillow to better adapt to the natural curves of the head and neck when sleeping on the side, reduce the pressure on the cervical spine, and provide a better wrapping feeling.

[0043] The upper body 1 and lower body 2 are made by sewing the pillowcase together. This integrated sewing process not only ensures the pillow's integrity and durability, but also prevents deformation during use, maintaining its height and shape. The pillowcase can be made of a breathable material, such as cotton or linen, to enhance its breathability and comfort. Furthermore, a layer of anti-mite material can be applied to the inside of the pillowcase to prevent the breeding of dust mites and improve the pillow's hygiene.

[0044] Example 3:

[0045] This embodiment differs from the previous one in that the upper body 1 and lower body 2 utilize different materials and structural designs to meet the needs of different users. The upper body 1 is filled with 95% high-quality, 800-fill-power white goose down, while the lower body 2 is filled with natural latex particles. This filling solution is particularly suitable for users who require higher breathability and comfort, providing ultimate softness and comfort while ensuring excellent support and breathability.

[0046] Specifically, the upper body 1 is filled with 95% high-quality white goose down with a fill power of 800. This filling material is extremely soft and comfortable, providing a comfortable, enveloping feeling while offering adequate breathability to prevent overheating during sleep. The lower body 2 is filled with natural latex particles. This filling material offers excellent support and breathability, while also possessing excellent resilience, providing sufficient support to prevent deformation after prolonged use and maintain the pillow's support and durability.

[0047] The internal filling volume of the first and third bodies 11, 13 is greater than that of the second body 12, resulting in the first and third bodies 11, 13 tilting upwards to form a butterfly shape. This design allows the pillow to better conform to the natural curves of the shoulders and head when sleeping on the side, reducing pressure on the cervical spine while providing a better sense of support. The middle of the second body 12 is divided by a central seam to form a central area 16 and two side areas. The central area 16 is lower than the side areas. This design allows the pillow to better conform to the natural curves of the head and neck when sleeping on the side, reducing pressure on the cervical spine while providing a better sense of support.

[0048] The upper body 1 and lower body 2 are made by sewing the pillowcase together. This integrated sewing process not only ensures the pillow's integrity and durability, but also prevents deformation during use, maintaining its height and shape. The pillowcase can be made of a breathable material, such as cotton or linen, to enhance its breathability and comfort. Furthermore, a layer of anti-mite material can be applied to the inside of the pillowcase to prevent the breeding of dust mites and improve the pillow's hygiene.

[0049] In summary, the double-layer composite structure design in this application achieves the adjustment of different hardness and support effects by combining a hard support layer with a soft wrapping layer. The one-piece sewing process ensures the integrity and durability of the pillow, improves the service life and stability of the pillow, and solves the problem of insufficient support of traditional pillows. The butterfly-wing design has a lower central part and higher two sides, which can better adapt to the natural curve of the head and neck when sleeping on the side, reduces the pressure on the cervical spine, reduces the pressure on the shoulders when sleeping on the side, improves overall comfort, and at the same time reduces the occurrence of ear pressure discomfort, improves blood circulation, promotes spinal alignment, and improves sleep quality. The gender-differentiated filling solution is specially designed for the differences in the body structures of men and women, and adopts different filling partitions and gram weight solutions to meet the specific needs of different users. Regardless of the size of the head or the width of the shoulders, they can find the support that best suits them, thereby improving the user's personalized sleep experience. Therefore, this application effectively overcomes the various shortcomings in the existing technology and has a high industrial utilization value.
