Description

Technical Field

[0001] The utility model relates to the technical field of pillows, and specifically relates to a vertical cotton spring pillow. Background Art

[0002] In the field of pillow design, traditional material combinations and structures often struggle to simultaneously meet the requirements of breathability, comfort, supportiveness, durability, and environmental friendliness. Traditional pillows mostly use sponge, ordinary non-woven materials, or a single spring structure. These materials are prone to problems such as deformation and collapse during long-term use, affecting sleep quality and health. In addition, the use of chemical adhesives in traditional production processes may also pose potential hazards to human health and the environment. Therefore, we have proposed a vertical cotton spring pillow. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a vertical cotton spring pillow, which solves the problems raised in the above background art.

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: A vertical cotton spring pillow includes a lower layer of vertical cotton, a spring assembly, and an upper layer of vertical cotton stacked in sequence. The lower layer of vertical cotton and the spring assembly, as well as the spring assembly and the upper layer of vertical cotton, are respectively bonded by a lower layer of hot melt film and an upper layer of hot melt film.

[0005] Further, several groups of spring assemblies are provided and are evenly arranged between the lower layer of hot melt film and the upper layer of hot melt film.

[0006] Further, the spring assembly includes a spring bag and a spring. The spring is located inside the spring bag, and the spring bag can deform following the contraction of the spring.

[0007] Further, the spring bag includes multiple bag body structures, which are sequentially connected to each other. Several springs are provided, and each spring is located in a corresponding bag body structure.

[0008] Further, the bag body structure is made of polyester spunbonded fabric and covers the outside of the spring.

[0009] Further, the melting points of the lower layer of hot melt film and the upper layer of hot melt film are both lower than the melting points of the lower layer of vertical cotton, the spring assembly, and the upper layer of vertical cotton.

[0010] Further, the four sides of the lower layer of vertical cotton and the upper layer of vertical cotton are fixed by sewing or hot pressing.

[0011] The utility model provides a vertical cotton spring pillow. Compared with the prior art, it has the following beneficial effects:

[0012] 1. By using 3D upright cotton as the filling material and combining it with a spring component, the pillow not only provides good support but also ensures excellent breathability and comfort. The three-dimensional structure of the 3D upright cotton and the elastic support of the spring component act together on the human body, effectively dispersing pressure and enhancing the sleep experience.

[0013] 2. The lower layer of upright cotton, the spring component, and the upper layer of upright cotton are bonded together by a hot melt film. This bonding method is not only firm and reliable but also effectively prevents the displacement and deformation of each layer of material during use, thereby extending the service life of the pillow and maintaining its stable performance.

[0014] 3. Compared with traditional chemical adhesives, the hot melt film, as an environmentally friendly bonding material, does not produce harmful substances during its use and is harmless to both the human body and the environment. At the same time, 3D upright cotton, as a new type of environmentally friendly material, is made of 100% polyester fiber single material and can be manufactured using recycled polyester fiber, with the proportion of recycled polyester fiber as high as 70 - 85%. Its production process is pollution-free and can be recycled, further enhancing the environmental performance of the pillow. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: an upright cotton spring pillow, which is composed of a lower layer of upright cotton 1, a lower layer of hot melt film 2, multiple groups of spring components 3, an upper layer of hot melt film 4, and an upper layer of upright cotton 5. Among them, the lower layer of upright cotton 1, the lower layer of hot melt film 2, multiple groups of spring components 3, the upper layer of hot melt film 4, and the upper layer of upright cotton 5 are stacked in sequence from bottom to top. The multiple groups of spring components 3 are evenly distributed between the lower layer of hot melt film 2 and the upper layer of hot melt film 4. The melting points of the lower layer of hot melt film 2 and the upper layer of hot melt film 4 are both lower than those of the lower layer of upright cotton 1, the spring components 3, and the upper layer of upright cotton 5. When manufacturing and producing this upright cotton spring pillow, the lower layer of upright cotton 1, the lower layer of hot melt film 2, multiple groups of spring components 3, the upper layer of hot melt film 4, and the upper layer of upright cotton 5 are stacked in sequence to form a five-layer stacked structure. Among them, both the lower layer of upright cotton 1 and the upper layer of upright cotton 5 contain 40% of low-melting-point fibers, and then they are put into an oven for baking (the baking temperature is 195°C, and the baking time is 4 minutes). The low-melting-point materials (that is, the 40% of low-melting-point fibers contained in the lower layer of upright cotton 1 and the upper layer of upright cotton 5, as well as the lower layer of hot melt film 2 and the upper layer of hot melt film 4) melt and bond. Subsequently, the combination is quickly taken out of the oven and put into a pillow mold for molding (the molding time is 180 seconds) before the low-melting-point materials cool and solidify. After the low-melting-point materials cool and solidify, the mold is opened, and the shaped upright cotton spring pillow is obtained.

[0022] The four sides of the lower layer of upright cotton 1 and the upper layer of upright cotton 5 are fixed by sewing or hot pressing, so that the spring components can be wrapped inside.

[0023] In addition, the spring component 3 is composed of a spring bag 31 formed by connecting several bag body structures in series and several springs 32. Each spring bag 31 wraps a spring 32, and the spring bag 31 can deform following the contraction of the spring 32.

[0024] Finally, when this upright cotton spring pillow is in use, it has the following advantages:

[0025] 1. Both the lower layer of upright cotton 1 and the upper layer of upright cotton 5 are prepared from a single polyester fiber material, which can be conveniently recycled, contributing to the sustainable development of the environment, and the recycled polyester fiber content used is as high as 70% - 85%, contributing to the circular economy;

[0026] 2. The spring component 3 is composed of multiple independent sleeves combined. The independent sleeves are composed of polyester spunbonded cloth covering the springs. The elasticity and supporting force of the sleeves can be changed by changing the spring wire diameter, coil diameter, and spring material inside the sleeves, so that spring groups with different hardness and different supporting properties can be obtained to meet the needs of different people for pillows;

[0027] 3. The lower upright cotton 1, the lower hot melt film 2, the upper hot melt film 4, and the upper upright cotton 5 are made of polyester material, the spring is made of metal material, and the sleeve wrapping cloth is made of polyester material. All components are chemically harmless, green and environmentally friendly.

[0028] 4. The air permeability of the upright cotton of the lower upright cotton 1 and the upper upright cotton 5 is better than that of the sponge, and there is an internal space formed by the support of the spring group in the middle. During pillow sleep, compression and rebound will occur due to posture changes, enabling continuous exchange of internal air and external air, and providing good air permeability and comfort.
