[0001] This application claims priority to German Utility Model Application No. 20 2023 104724.6, filed on August 18, 2023, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This disclosure generally relates to the field of mattress technology. Specifically, it relates to space-saving mattress packaging, especially packaging for new mattresses, such as for retail and shipping. Background Technology
[0003] Mattresses, especially those with a thickness of at least 18 cm, have long been used as a support and / or lying surface for users, and have been continuously improved to enhance user comfort and achieve ergonomic lying positions. To enhance lying comfort, mattresses can, for example, have adjacent zones, areas, support zones, and / or sections along their longitudinal direction with varying firmness, compressibility, compressibility, and / or elasticity. This allows the user's sinking depth to adapt to their body shape. It also ensures that the spine remains as straight as possible when the user is lying on their side. Similarly, in the supine position, the spine can be supported to maintain its natural S-shape. By providing multiple support zones or areas with different compressibility, the weight distribution of the user on a particular lying surface of the mattress can be advantageously considered, thereby ensuring an ergonomic body posture for the user in various sleeping positions and / or sleeping postures.
[0004] Mattresses typically have an outer cover. The outer cover used for a mattress (hereinafter referred to as the "mattress cover"), as commonly known in practice, is usually designed to tightly enclose the mattress core. The mattress core has a length and width that may be relatively large relative to its height on its upper and lower surfaces, thus forming a surface for a person to lie on.
[0005] A mattress cover typically consists of a fabric area forming the top surface and a fabric area forming the bottom surface. For removable covers that allow the mattress insert to be inserted into or removed from the cover, a closure, such as a zipper, is usually provided for this purpose.
[0006] Depending on the structure of the cover, the fabric areas of the top and bottom surfaces can be composed of separate fabric pieces forming the corresponding lying or bottom surfaces, and optionally connected to each other by fabric strips forming long and short sides. These fabric strips are usually sewn to the fabric pieces of the top and bottom surfaces, and the sewn joints can be covered by binding tape or piping tape.
[0007] In practice, known covers, especially mattress covers, often use ventilation strips made of highly breathable materials on the long and short sides of the cover because conventional cover materials usually have low gas permeability; otherwise, the mattress core or pillow core would not be adequately ventilated.
[0008] Modern mattresses are typically made of foam, at least partially or primarily. For example, latex, viscoelastic foam, cold foam (such as polyurethane cold foam), or polystyrene can be used. Furthermore, mattresses can be equipped with fillings made of a variety of materials.
[0009] Newly manufactured mattresses are typically packaged in a space-saving manner, such as for easy mail-order sales. Space-saving mattress packaging is usually achieved by compressing the mattress, for example, using pressure plates or rollers to expel air from inside. Mattresses compressed in this way can be reduced to a fraction of their original thickness. For commercial purposes, such as mail order, the compressed mattress is usually wrapped in packaging material, often plastic, which encloses the mattress like a bag. The packaged mattress can then be folded and / or rolled up to further reduce its size.
[0010] To prevent a mattress from springing back to its original shape, compressed and folded and / or rolled-up mattresses must remain compressed. Therefore, the mattress packaging must be sufficiently tear-resistant or strong to prevent damage to the mattress. Thus, mattresses are typically provided with sufficiently strong plastic packaging.
[0011] However, plastic packaging is unsustainable and causes environmental problems. As sustainability and environmental protection become increasingly important, people want to avoid plastic packaging as much as possible, but at the same time, it is essential to ensure that mattress packaging has sufficient stability. Summary of the Invention
[0012] Embodiments of this disclosure provide an advantageous way to obtain more environmentally friendly and sustainable mattress packaging, while the packaging still has sufficient stability to prevent accidental loosening or damage due to mattress expansion.
[0013] This is achieved, in particular, through the subject matter of the independent claims. Preferred embodiments and further improvements are set forth in the dependent claims and the following description.
[0014] This disclosure relates to a packaged mattress. The mattress is disposed inside the package. The package comprises at least one layer of paper. A coating formed of a weldable material is provided on at least one side of the paper layer. The basis weight of the paper layer can be from 80 g / m² to 130 g / m², particularly from 84 g / m² to 110 g / m². The mass ratio and / or volume ratio between the paper layer and the coating is between 90:10 and 99:1.
[0015] The paper layer is composed of paper, a sheet material essentially made of plant-derived fibers, typically formed by dehydrating a fiber suspension on a screen. The resulting fiber felt is compacted and dried to obtain paper. Paper layers with a basis weight of 80 g / m² to 130 g / m² have proven to provide sufficient strength for packaging and transporting the mattresses manufactured herein. Paper layers with a basis weight of 82 g / m² to 86 g / m², particularly 84 g / m², are more economical and therefore preferred. According to this disclosure, the paper layer may, for example, be a strip of paper cut to size according to the mattress dimensions.
[0016] The weldable material is a material that, under external action, can form a shape-fit and / or material-fit connection with itself and / or with the paper layer. The resulting connection is also referred to below as a "weld". External actions include, for example, heating the weldable material, applying pressure, or ultrasonic treatment. Combinations may also be used, such as heating and, especially, simultaneous pressure. In this case, such treatment to create the connection is referred to as "welding". The connection is inseparable without damage, i.e., a permanent connection with high strength. The connection formed according to this disclosure is explicitly not an adhesive connection. Adhesive connections typically require curing, resulting in longer production processes and higher costs, thus adhesive connections are comparatively disadvantageous and less economical. Therefore, the mattress packaging preferably does not contain adhesive connections.
[0017] The mass and / or volume ratio between the paper layer and the coating made of weldable material is between 90:10 and 99:1, where the higher proportion always refers to the paper layer and the lower proportion refers to the weldable material in the coating. In other words, the paper mass fraction of the packaging is between 90% and 99%, while the coating mass fraction is between 10% and 1%. Alternatively, a volume ratio can be used as the unit of measurement. In this case, the paper volume fraction of the packaging is between 90% and 99%, while the coating volume fraction is between 10% and 1%. Preferably, the packaging is entirely composed of paper layers and a coating of weldable material. Such packaging ensures a reliable seal by welding the coating. Furthermore, the packaging is primarily composed of renewable raw materials and is recyclable. Therefore, it is significantly more environmentally friendly than the plastic packaging commonly used to date.
[0018] The mattress preferably includes an upper side, which is preferably configured to support a person in a lying position, as described further below. Additionally, the mattress preferably includes a lower side disposed opposite the upper side. If the mattress is designed as a flip-up mattress, the lower side may also be configured to support a person in a lying position. Finally, the mattress preferably includes a wraparound (front) side composed of four sub-surfaces arranged substantially orthogonally to each other, connecting the upper and lower surfaces of the mattress. The upper and lower surfaces of the mattress are preferably separated by the thickness of the mattress. Accordingly, the side extends circumferentially across the thickness of the mattress along the edges of the upper and lower surfaces.
[0019] Preferably, the packaging comprises a first paper layer (having at least one layer of weldable material coating) and a second paper layer (having at least one layer of weldable material coating). The first paper layer with at least one layer of weldable material coating preferably completely covers the upper surface of the mattress, and in particular, it should extend beyond the boundary of the upper surface of the mattress. The second paper layer with at least one layer of weldable material coating preferably completely covers the lower surface of the mattress, and in particular, it should extend beyond the boundary of the lower surface of the mattress. The aforementioned extended areas of the first and second paper layers are preferably welded together.
[0020] For example, the first and second paper layers can extend around the upper and lower surfaces of the mattress, particularly along the four sides. Accordingly, in this case, the first and second paper layers can be welded together at the weldable material coating on each perimeter, particularly along the four sides. This forms a weld seam, through which the first and second paper layers are welded together. In this case, the weld seam completely surrounds the mattress and is preferably located on the side. "Provided on the side" means that the weld seam is preferably located on the side of the mattress, preferably on one of the four sub-surfaces of the mattress side. The weld seam being located on the side of the mattress means that the weld seam faces the side of the mattress, preferably directly opposite it, for example, against it or extending outwards from it. For example, the weld seam is preferably located at the center of the mattress side along the thickness direction.
[0021] Alternatively, the packaging may consist of only a single layer of paper, for example, folded at least once around the mattress. The mattress may be placed, for example, in a paper bag made of this paper layer. Depending on the structure of the paper bag, welds may only need to be formed on three sides, two sides, or only on one side (preferably the side) by welding the weldable coating. Thus, the mattress packaging according to this disclosure may have welds on all four sub-surfaces of the mattress side, or only on three, two, or one sub-surface. In other words, the packaging includes at least one weld obtained by welding a weldable material coating, wherein the weld is provided on at least one, preferably at least two, at least three, or at least four sub-surfaces surrounding the mattress side.
[0022] The weld extends along each sub-surface of the side. The weld has a width that can be measured parallel to the plane of the paper layer. Therefore, the width is preferably measured in the plane of the paper layer, i.e., particularly perpendicular to the normal direction of the paper layer or the upper / lower surface of the mattress. Conversely, the weld has its minimum dimension along the normal direction of the paper layer or the normal direction of the upper / lower surface of the mattress. The width of the weld is measured, for example, in a direction perpendicular to the thickness direction of the mattress. In other words, the width of the weld can be, for example, parallel to the upper or lower surface of the mattress. The weld obtained by welding the coating preferably has a width of at least 2 cm, more preferably at least 3 cm, at least 4 cm, at least 5 cm, at least 6 cm, at least 7 cm, at least 8 cm, at least 9 cm, or at least 10 cm. A larger weld width increases strength and ensures that the weld will not accidentally open.
[0023] In principle, any material suitable for welding to form a weld as described herein can be used as a weldable material for coating the paper layer. Preferably, the weldable material comprises or is composed of a thermoplastic material. More preferably, the weldable material comprises or is composed of thermoplastic polyurethane (TPU). This material is particularly suitable for this application.
[0024] To further improve environmental compatibility, it is preferable that at least one coating layer is composed of a biodegradable weldable material, or at least partially includes such a material. These materials include so-called bioplastics, such as thermoplastic starch and its derivatives, cellulose and its derivatives, lignin, polylactic acid (PLA), polyhydroxy fatty acids (PHB, PHV), etc.
[0025] The at least one coating formed from a weldable material preferably has a layer thickness of 10 µm to 30 µm, particularly 15 µm to 25 µm, for example 20 µm. This layer thickness has proven sufficient to form a reliable weld. The use of a particularly thin coating further reduces the environmental impact of the packaging described in this disclosure. The coating can seal pores and channels in the paper layer. In particular, the coating is configured to cover or seal the paper layer, making it airtight. Furthermore, the coating preferably has sufficient pressure resistance to enable the vacuum treatment of the mattress as described below.
[0026] The mass ratio and / or volume ratio between the paper layer and the coating is preferably between 91:9 and 98:2, particularly preferably between 92:8 and 97:3, or 93:7 to 96:4, or 94:6 to 95:5, for example, 95:5. Accordingly, the mass fraction of the paper layer in the packaging is preferably between 91% and 98%, particularly preferably between 92% and 97%, or 93% to 96%, or 94% to 95%, for example, 95%. Alternatively or concurrently, the volume fraction of the paper layer in the packaging is preferably between 91% and 98%, particularly preferably between 92% and 97%, or 93% to 96%, or 94% to 95%, for example, 95%. The mass fraction of the coating in the packaging is preferably between 2% and 9%, particularly preferably between 3% and 8%, or 4% to 7%, or 5% to 6%, for example, 5%. Alternatively, the volume fraction of the coating in the packaging is preferably between 2% and 9%, particularly preferably between 3% and 8%, or 4% and 7%, or 5% and 6%, for example 5%.
[0027] In principle, at least one paper layer may have a coating formed of a weldable material on one or both sides. Preferably, the coating completely covers the paper layer on one or both sides. Double-sided coating simplifies the manufacturing process, for example, the orientation of the paper layer does not need to be considered during welding. However, considering the recyclability and environmental friendliness of the packaging according to this disclosure, it is more preferable that the paper layer is coated with a weldable material only on one side. Preferably, the single-sided coating is provided on the side of the paper layer or packaging facing the mattress. In other words, the single-sided coating is provided on the inside of the packaging.
[0028] Paper layers can essentially contain recycled and virgin fibers (also known as secondary and primary fibers) in any combination. However, it is more preferred that the paper layer contains at least part of virgin / primary fibers, or even consists entirely of virgin / primary fibers. This is because virgin fibers are of superior quality to recycled / secondary fibers, especially in terms of strength (and thus the tear resistance of the paper layer). Due to declining global paper consumption, the quality of recycled fibers continues to deteriorate, making it necessary to use at least part or entirely virgin fibers to ensure the required strength of the paper layer. Depending on the desired appearance, the fibers used in the paper layer can be bleached or unbleached.
[0029] Furthermore, at least one paper layer may contain at least one type of printed content. For example, the printed content may include instructions on where and / or how to safely open the packaging without damaging the mattress. For instance, the printing may suggest tearing the packaging directly rather than cutting it, as knives or scissors could damage the mattress. Since paper packaging as described in this disclosure is easier to tear than plastic packaging, it facilitates mattress handling and reduces the risk of accidental damage to the mattress when opening the packaging.
[0030] To prevent accidental expansion of the mattress inside the packaging, it can be vacuum-packed. Vacuuming the mattress can supplement or replace external compression to reduce its size. In other words, it creates negative pressure inside the packaging (i.e., the space containing the mattress). Preferably, this is achieved by removing air from the packaging cavity and the mattress itself. Vacuuming makes the mattress firmer, resulting in less displacement of the mattress material. Therefore, placing the mattress in a vacuum environment can combat both material aging (such as oxidation) and material fatigue.
[0031] To facilitate vacuuming of the mattress, the packaging may include a vacuum tube extending from the mattress within the packaging to the external environment. This vacuum tube allows air to be extracted from the interior of the packaging, creating a vacuum. Preferably, the vacuum tube comprises a weldable material, particularly on its inner side, and preferably possesses malleable deformation properties, such as compressibility. This allows the vacuum tube to be sealed simultaneously with the welding of the coating to seal the packaging, thus achieving an airtight seal for the packaging along with the vacuum tube.
[0032] To reduce the overall dimensions of the mattress, it can be compressed and / or folded and / or rolled up. In particular, the mattress can be compressed inside the packaging, for example, by external pressure and / or vacuuming. Furthermore, to achieve a favorable packaging size, the mattress can be folded and / or rolled up along with the packaging. For example, the mattress can be folded along its short side and rolled up along its long side. A preferred embodiment specifies that the mattress, along with its packaging, is folded at least once or at least twice, particularly along its narrow side. Preferably, the folded mattress is also rolled up, particularly along its long or wide side.
[0033] In addition, fasteners can be provided around the packaging to prevent the compressed and / or folded and / or rolled mattress from returning to its original shape. In other words, the fasteners prevent the mattress from losing its compressed state and expanding again. Furthermore, the fasteners prevent the mattress and its packaging from unfolding or unrolling. The fasteners can be, for example, adhesive tape. Alternatively, the fasteners can be wrappings, such as paper wrappings. Preferably, the fasteners (especially paper wrappings) cover the entire outer surface of the rolled and / or folded mattress, but not the end faces. For example, when the mattress, along with its packaging, is rolled into a cylinder, the fasteners are preferably arranged on the entire cylindrical side of the rolled mattress. Any counter-pressure exerted by the mattress on the fasteners is thus distributed over a larger area, preventing the fasteners from accidentally detaching. At the front end of the cylinder, i.e., at the bottom surface of the cylinder, the fasteners can be open.
[0034] The fasteners (especially the shrouds) preferably comprise paper or are preferably made of paper. Durable, tear-resistant paper is particularly suitable for this application. Therefore, it is preferred that the paper used for the fasteners is, for example, at least partially or entirely composed of virgin / primary fibers. Alternatively or additionally, the area mass of the paper used for the fasteners may be specified to be at least 80 g / cm², or at least 90 g / cm², or at least 100 g / cm², or at least 110 g / cm², or at least 120 g / cm², or at least 130 g / cm², or at least 140 g / cm², or at least 150 g / cm², or at least 160 g / cm², or at least 170 g / cm², or at least 180 g / cm², or at least 190 g / cm², or at least 200 g / cm². For example, the paper used for the fasteners may have the same properties as the paper used for at least one layer of packaging. In particular, the paper used for the fasteners may also have a corresponding coating. Therefore, the relevant descriptions of the paper layers and their coatings are hereby cited and applied.
[0035] The fastener may also have printed content and / or predetermined tear points to facilitate opening. These predetermined tear points may, for example, include perforated lines and / or tear strips. For instance, the printed content may indicate where and / or how to safely open the fastener without damaging the mattress or packaging. For example, the printing may suggest that the fastener should not be opened by cutting, as knives or scissors may damage the mattress or packaging, but rather by tearing it open directly. This method is particularly effective if the fastener is a paper bandage.
[0036] It can also be stipulated that the packaged mattress, especially along with the fasteners, includes further outer packaging. For example, the mattress, along with its packaging, especially along with the fasteners, can be housed inside the outer packaging. The outer packaging can include a cardboard box, such as a shipping box. Therefore, the packaged mattress can be transported directly within the outer packaging. Because the mattress is particularly small in size due to folding and / or rolling and / or vacuuming, and is held together by the fasteners, the outer packaging can have a relatively small size. The outer packaging therefore does not need to withstand significant forces and can be particularly inexpensive.
[0037] The following section will describe the mattress to be packaged and its outer cover in more detail. The characteristics of the mattress and its cover described herein have proven particularly suitable for packaging with at least one layer of paper. In particular, the physical properties of a mattress with a corresponding outer cover, vacuum-packed and / or compressed and / or rolled and / or folded, are optimized for paper packaging, ensuring that the packaging described herein will not tear or leak even after prolonged storage in its packaged state.
[0038] Mattresses may be formed, for example, of foam or foam materials, particularly viscoelastic foam, cold foam, point-resilience foam, and / or polyurethane foam, or contain the aforementioned foams. They may be wholly or at least partially composed of such foam or foam materials. Such mattresses offer excellent lying comfort and are particularly compatible with and easy to package as described herein.
[0039] The mattress may also include a mattress cover that at least partially covers the mattress. Preferably, the mattress cover completely covers the mattress. Furthermore, the mattress cover is preferably configured to be removable or replaceable. For this purpose, the mattress cover includes a first half and a second half, which are connected to each other at least on at least a portion of the outer periphery of the mattress by a closure (especially a zipper). In particular, the closure extends along the side of the mattress. Therefore, the first and second halves of the mattress cover are preferably configured such that they completely cover one of the upper and lower sides of the mattress, respectively. Overall, the mattress can thus be completely covered by the mattress cover.
[0040] The mattress cover and / or the overlay fabric of the mattress cover may be at least partially composed of spacer fabric, especially weft-knitted and / or warp-knitted fabric. Such spacer fabrics can advantageously facilitate the exchange of air and moisture.
[0041] According to one embodiment, a mattress cover includes a cover fabric comprising at least one upper layer and one lower layer, wherein the upper and lower layers are at least partially overlapped, and at least the upper layer of the cover fabric is composed of a weft-knitted fabric (e.g., 3D weft-knitted fabric), and at least a plurality of recesses are formed on the outer side of the upper layer opposite to the lower layer. The mattress cover may be composed of this cover fabric. The description of the cover fabric herein also applies to mattress covers, and vice versa.
[0042] The lower layer can be a substantially closed structure and / or a closed knitted structure, while the recesses can form openings or holes in the upper layer. Therefore, these recesses can be defined by the lower layer. Optionally, the recesses are at least partially defined by spacer yarns between the upper and lower layers. The outline of the upper recesses can be defined by the knitting loops of the upper weft-knitted fabric.
[0043] Thus, mattress covers take advantage of weft-knitted fabrics, such fabrics, for example, containing spacer structures with loops, the spacer structures being at least partially composed of woven monofilament or multifilament spacer yarns.
[0044] In addition, the recesses formed on the outer side allow for better air circulation, greater breathability, and / or stronger moisture transfer.
[0045] Weft-knitted fabrics used for mattress covers differ from warp-knitted fabrics, which are commonly used for covering materials, in several ways. For example, warp-knitted fabrics are typically produced on so-called warp knitting machines, while weft-knitted fabrics are typically produced on knitting machines, which are further categorized into plain knitting machines and circular knitting machines. In the production of warp-knitted fabrics, loops are formed around the warp yarns (hence the name warp knitting machine), and the loops are arranged vertically. Because the loops are arranged in a "chain," warp-knitted fabrics are stable, rigid, inelastic, and non-stretchable. In contrast, the loops in weft-knitted fabrics are not arranged in a "chain," and the loops themselves are elastic and stretchable in both the horizontal and vertical directions. Compared to warp-knitted fabrics, weft-knitted fabrics are particularly elastic and stretchable in both the horizontal and vertical directions, while warp-knitted fabrics are completely inelastic and non-stretchable. Warp-knitted fabrics are therefore static and rigid fabric structures with almost no elasticity. Furthermore, warp-knitted fabrics have a stiff, hard, and plastic-like hand feel; in contrast, spaced-knitted fabrics can have a woven / fabric-like and soft hand feel. In addition, in warp-knitted fabrics, the fiber ends are usually exposed on the fabric surface, resulting in an itchy and rough feel; while weft-knitted fabrics usually have a softer feel, which is partly due to the stronger elasticity of weft-knitted fabrics and the more refined finishing compared to warp-knitted fabrics.
[0046] Mattress covers (including mattress protectors) may include a top and / or a bottom side, each of which may be designed as a surface for the user to lie on. However, the bottom side is only an optional lying surface and does not necessarily need to be completely enclosed.
[0047] In the context of this disclosure, the recesses formed at least on the outer side of the upper layer of the covering fabric must be strictly distinguished from the meshes constituting the covering fabric, the lower layer, and / or the upper layer. The recesses may be larger in size than the meshes; for example, the recesses may have a cross-sectional area that is several times (about 5 to 100 times or more) the average cross-sectional area of the covering fabric meshes.
[0048] Outer fabrics can generally be designed as double-layered, triple-layered, or multi-layered structures. In particular, outer fabrics can be made entirely of weft-knitted fabrics and / or 3D weft-knitted fabrics.
[0049] In a double-layered structure of an overlay fabric, the upper and lower layers can be at least partially connected and / or woven together, for example, by using yarns from the upper and / or lower layers at specific locations. Alternatively or additionally, connecting yarns can be used to connect the upper and lower layers. If the overlay fabric has three or more layers, one or more intermediate layers of the overlay fabric can be connected and / or woven together with the upper and / or lower layers. Alternatively or additionally, connecting yarns can also be used here to connect at least two layers of the overlay fabric, such as an upper layer, a lower layer, and / or one or more intermediate layers.
[0050] Mattress covers can be easily manufactured on large circular knitting machines with high throughput and so-called "three-way technology," thus offering high economic efficiency.
[0051] The recess can be configured to open outwards (i.e., towards the user) and / or have an externally open cross-section. Therefore, the recess can correspond to an opening. Generally, recesses offer advantages in terms of air exchange and moisture transfer, as well as buffering temperature fluctuations. Recesses can also provide greater elasticity, a soft feel to the user, and allow the overlay to optimally conform to the user or their head without the discomfort caused by the brittle spacer yarns commonly found in warp-knitted fabrics.
[0052] The recesses formed at least on the outer side of the upper layer can also provide and / or constitute the mesh structure of the covering fabric. In other words, the covering fabric can contain a mesh structure, such as a honeycomb mesh structure, at least on the outer side, and is constituted by these recesses.
[0053] The recesses in the mesh structure and / or the covering fabric can be arranged in a regular manner on the outside of the covering fabric. In other words, the recesses can be regularly arranged and / or form a regular pattern. However, irregular arrangements, such as arrangements forming specific patterns, are also conceivable.
[0054] These recesses (e.g., outwardly open recesses) can have a variety of geometries, such as circular, angular, elliptical, oval, polygonal, elliptical, or any shape with an open cross-section.
[0055] For example, the recesses can be formed in a honeycomb pattern. Alternatively or additionally, the recesses can have circular, rounded, angular, square, rectangular, polygonal, triangular, elliptical, oval, and / or polygonal cross-sections.
[0056] According to one embodiment, the upper and / or lower layers of the covering fabric are at least partially composed of natural fibers.
[0057] Using natural fibers (e.g., incorporated into and / or woven into weft-knitted fabrics) can enhance the sustainability and / or eco-friendliness of mattress covers ("covers"), for example, because natural fibers can be derived from renewable resources. Natural fibers also exhibit higher resilience and / or durability. Furthermore, natural fibers provide a soft, comfortable feel. They also offer greater skin compatibility, breathability, and / or odor neutrality. In addition, natural fibers enable cost-effective production of mattress covers.
[0058] According to one embodiment, the natural fiber is animal hair fiber, wool fiber, cotton fiber, hemp fiber, eucalyptus fiber, bamboo fiber, flax fiber, wood fiber, viscose fiber, sesame fiber, silk fiber, plant fiber, or a combination thereof. Compared with synthetic fibers, such natural fibers may exhibit better performance in terms of sustainability, odor neutrality, skin compatibility, durability, and / or toughness.
[0059] According to one embodiment, the weight percentage of natural fibers in the upper, lower, and / or one or more intermediate layers of the covering fabric (e.g., relative to each layer or the entire covering fabric) is from 2% to 99%, for example, at least 5%, at least 10%, at least 15%, at least 20%, and / or at least 25%. A natural fiber percentage of at least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, or 75% is also contemplated.
[0060] According to one embodiment, the proportion of natural fibers in the upper layer (e.g., weight and / or volume proportion, relative to each layer or the entire covering fabric) is greater than the proportion of natural fibers in the lower layer and / or one or more intermediate layers. For example, this proportion in the upper layer may be at least twice the corresponding proportion of natural fibers in the lower layer and / or one or more intermediate layers.
[0061] According to one embodiment, the upper layer is substantially and / or almost entirely (e.g., entirely) composed of natural fibers, while the lower layer and optionally one or more intermediate layers are substantially and / or almost entirely (e.g., entirely) composed of synthetic fibers.
[0062] According to one embodiment, the upper and / or lower layers of the covering fabric are at least partially composed of textured, twisted yarns, particularly multifilament yarns, such as polyester yarns, polyethylene yarns, and polyamide yarns. This can provide a soft and comfortable feel.
[0063] According to one embodiment, the upper and / or lower layers of the covering fabric are at least partially composed of monofilament yarns, particularly polyester yarns, smooth polyester yarns, polyethylene yarns, smooth polyethylene yarns, polyamide yarns, and / or smooth polyamide yarns. Using monofilament yarns on the inside of the covering fabric facing the mattress core facilitates the insertion or removal of the mattress core. The mattress core, for example, refers to the mattress body without a mattress cover.
[0064] For example, the overlay fabric made of weft knitted fabric can be formed as at least two layers, wherein the upper layer forms the outer layer and the inner / lower layer is a fabric layer, preferably made of polyester fiber fabric, polyethylene fiber fabric and / or polyamide fiber fabric.
[0065] The inner / lower layer may be, for example, a smooth fabric layer, or it may be jacquard woven and / or patterned, and its outer side may be overlaid with a weft-knitted upper layer composed of textured, twisted yarns (especially multifilament yarns).
[0066] According to one embodiment, the overlay fabric further includes an intermediate layer, which is woven together with the upper and / or lower layers at least in some locations and / or at least in some areas. This intermediate layer can be used to increase the volume of the overlay fabric, thereby improving lying comfort.
[0067] According to one embodiment, the intermediate layer is at least partially composed of monofilament yarns, particularly polyester yarns, smooth polyester yarns, polyethylene yarns, smooth polyethylene yarns, polyamide yarns, and / or smooth polyamide yarns.
[0068] According to one embodiment, the intermediate layer is at least partially composed of multifilament yarns, such as textured, twisted multifilament yarns, for example, made of polyester yarns, polyethylene yarns, or polyamide yarns.
[0069] According to one embodiment, the intermediate layer is at least partially composed of natural fibers. This provides the aforementioned advantages of natural fibers.
[0070] According to one embodiment, the recess extends at least substantially along the thickness direction of the upper layer, and, where applicable, also along the intermediate layer. In particular, the recess may penetrate the upper layer completely, thereby forming and / or manifesting as an opening in the upper layer.
[0071] For example, the recess can extend at least substantially through the entire thickness of the upper layer, i.e., from the outside to the inner / lower layer, or close to it, thereby achieving optimal microclimate control regarding air and moisture exchange between the two sides of the overlay fabric. Furthermore, the depth of the recess can increase the softness of the upper layer, which is composed of weft-knitted fabric, thus improving the hand feel.
[0072] The overlay fabric can also be formed as a three-layer fabric with an intermediate layer, for example, the intermediate layer is woven together with the upper layer and filled with monofilament yarn. This allows for the stabilization of frequently required weft-knitted fabrics and an improvement in tactile volume while maintaining high air and moisture permeability. The monofilament yarn can be made at least partially of polyester, polyamide, and / or polyethylene, but other synthetic fibers can also be used.
[0073] To give the outer surface or outer side of the weft-knitted fabric a particularly smooth and comfortable feel, the surface or outer area surrounding the concave part can be shaped with a finer knitted mesh compared to other outer areas.
[0074] According to one embodiment, the upper layer constitutes 50% to 70% of the weight of the covering fabric, particularly 55% to 60%. Studies have shown that this weight ratio is particularly advantageous in terms of comfort and microclimate control. Furthermore, this ratio is also particularly suitable for the packaging described herein.
[0075] According to one embodiment, the weight percentage of the lower layer in the covering fabric is 20% to 30%, particularly 25% to 30%.
[0076] According to one embodiment, the intermediate layer accounts for 10% to 20% of the weight of the covering fabric, particularly 15% to 20%.
[0077] When using filler yarn, it has been determined that the best results can be obtained in terms of air permeability, stabilization and volume when the weight ratio of the interlayer in the cover fabric is 10% to 20%, especially 15% to 20%.
[0078] According to one embodiment, the basis weight of the covering fabric is 250 g / m² to 300 g / m². Thus, the covering fabric, while meeting the required durability, also has a weight that is easy to handle during manufacturing and use.
[0079] According to one embodiment, the covering fabric is rubberized, coated and / or latexed on at least one side (e.g., the outer side, inner side, bottom side and / or top side) to prevent moisture and / or water penetration.
[0080] According to one embodiment, the covering fabric forms an essentially consistent structure on all sides. In other words, the mattress cover can have a consistent structure on the top, bottom, and any long and short sides, although it is also conceivable in principle to form different structures on different sides of the cover.
[0081] Using the same design on all sides can significantly simplify the production process, and because the overlay fabric is highly breathable, it can also eliminate the need for ventilation strips commonly found on the transverse and longitudinal sides of known covers (especially mattress covers).
[0082] In addition, handles can be sewn onto the mattress cover to facilitate the moving and handling of the covered mattress.
[0083] The mattress cover may also be washable, for example, at temperatures of at least 30°C, at least 40°C, at least 50°C, at least 60°C, at least 70°C, at least 80°C, or at least 90°C.
[0084] According to one embodiment, the mattress has first and second sides and includes at least a head support area for supporting the head, a neck support area for supporting the neck, a shoulder support area for supporting the shoulders, a lumbar support area for supporting at least part of the spine, and a pelvic support area for supporting the pelvis.
[0085] According to one embodiment, the head support area, neck support area, shoulder support area, lumbar support area, and pelvic support area have at least partially different contour structures on the first and / or second sides of the mattress. Such contour structures can be contoured and / or structured such that at least a portion of each support area (i.e., the head, neck, shoulder, lumbar support, and / or pelvic support areas) differs from each other in firmness, compressive firmness, and / or firmness grade, and / or makes the compressive firmness of the mattress (or mattress elements) differ from each other at least in certain areas. The mattress can also be a flip-up mattress, thereby optionally providing different firmness grades.
[0086] To achieve an ergonomic and comfortable lying position, a mattress (or its components) can be divided into different support zones and / or sections. Specifically, a mattress may include one or more head support zones, one or more neck support zones, one or more shoulder support zones, one or more lumbar support zones, and one or more pelvic support zones. Different support zones may have different compression firmness, firmness grades, and / or elasticity, allowing the user to sink into the outer surface of each support zone to varying depths or to receive support in different ways. Different support zones can also be used to distribute the user's weight to at least a portion of the first and / or second outer sides. For example, the compression firmness of different support zones can be used to account for the fact that the user's head weight is lower than their pelvis. The compression firmness of different support zones can also ensure that the user's spine or back remains straight (e.g., when the user is lying on their side) or in a typical S-shape (e.g., when the user is lying on their back).
[0087] Different compression stiffnesses in different support zones can be achieved by using different materials (e.g., mattress foams and / or polyurethane foams of varying firmness), different contour structures, and / or different structures on the first and / or second outer sides. Such contour structures may include, for example, grooves, ribs, ridges, cuts, excisions, transverse grooves, recesses, channels, depressions, and / or cavities.
[0088] According to one embodiment, the mattress (or its elements) comprises a first half and a second half relative to a central transverse axis and / or a central transverse plane, the two halves being arranged one behind the other along the longitudinal axis of the mattress. In each half, the mattress (or one or more mattress elements) includes a head support area, a neck support area, a shoulder support area, a lumbar support area, and a pelvic support area. Thus, the two head support areas, neck support areas, shoulder support areas, lumbar support areas, and pelvic support areas of the mattress (or one or more mattress elements) can be arranged in a mirror-symmetrical manner relative to the central transverse axis and / or the central transverse plane.
[0089] According to one embodiment, the first and second halves of the mattress (or one or more mattress elements) are symmetrical with respect to the central transverse axis and / or central transverse plane of the mattress or reclining furniture, particularly mirror symmetry. The mattress (or individual mattress elements) can be mirror symmetrical, especially in terms of the design of the support zones and the structuring and / or contouring of the support zones.
[0090] Each support zone may be formed in the first and second halves of the mattress (or one or more mattress elements) as follows: a head support zone extends from each end of the mattress toward the central transverse axis; each head support zone is followed by a neck support zone, which extends further toward the central transverse axis of the mattress; each neck support zone is followed by a shoulder support zone, which extends further toward the central transverse axis; each shoulder support zone is followed by a lumbar support zone, which extends toward the central transverse axis; each lumbar support zone is followed by a pelvic support zone, which extends toward the central transverse axis.
[0091] According to one embodiment, the first and / or second side of the mattress includes at least one recess and / or at least one transverse groove in at least one portion area. One or more transverse grooves may be formed in each support area. The transverse grooves in different areas may differ from each other in terms of number, geometry, cross-section, size, depth, etc.
[0092] The transverse groove may be substantially parallel to the transverse axis of the reclining furniture and extend across the entire width of the first and / or second side of the mattress. A single transverse groove may appear as a macroscopic recess, cut, or cutout.
[0093] According to one embodiment, the mattress includes at least two mattress elements that are at least partially stacked on top of each other. Alternatively or additionally, the mattress includes at least a first mattress element and a second mattress element that are at least partially stacked on top of each other. The mattress may also include more than two mattress elements. The thickness of each mattress element (measured along directions perpendicular to the longitudinal and transverse axes) may be the same or different from each other.
[0094] According to one embodiment, each of the two mattress elements has an outer surface and a contact surface, wherein the contact surface of the first mattress element is at least partially in contact with the contact surface of the second mattress element, and the outer surface and / or contact surface of at least one of the first and second mattress elements includes a contour structure, particularly a contour structure having one or more transverse grooves. For example, the contour structure may be provided on one or both outer surfaces. Optionally, the contour structure having one or more transverse grooves may be additionally or exclusively formed on one or both contact surfaces.
[0095] In particular, each mattress element may have contoured structures on its outer and contact surfaces, and these contoured structures may be different from each other. If contoured structures are provided on both contact surfaces, the contoured structures of the two mattress elements may optionally at least partially engage with each other and / or correspond to each other.
[0096] According to one embodiment, the outer surface and / or contact surface of a first mattress element includes a first contour structure, and the outer surface and / or contact surface of a second mattress element includes a second contour structure, wherein the first contour structure is at least partially different from the second contour structure to allow the firmness rating of the first mattress element to differ from that of the second mattress element. The contour structure may, for example, include different transverse grooves.
[0097] The firmness or compressive firmness of the first and second mattress elements can also be influenced by the choice of materials for each mattress element, such as different types of foam (e.g., polyurethane foam). Furthermore, the firmness rating can be influenced by the corresponding structure, such as grooves, slots, ribs, channels, cuts, retractions, recesses, channels, depressions, and / or cavities formed in the first and / or second outer surfaces and / or the first and / or second contact surfaces. Additionally, the connection between the first and second mattress elements can also be affected, particularly by selecting and / or designing contoured structures on at least one contact surface. Alternatively or additionally, the firmness rating can vary in different areas of the mattress elements, for example, through material selection, contouring and / or structuring of the outer surfaces, and design of the contact surfaces. For example, the shoulder support area can be designed to be slightly softer than the neck support area, causing the user's shoulders to sink deeper into the outer surface of the mattress relative to the neck, especially when the user lies on their side on the outer side of the respective mattress element.
[0098] According to one embodiment, at least one of the first contact surface and the second contact surface includes a profile structure with one or more transverse grooves in at least one partial region. This can further enhance or adjust the support characteristics.
[0099] According to one embodiment, the contour structure is exclusively formed on the second contact surface of the second mattress element. Alternatively or additionally, the contour structure is not formed on the first contact surface of the first mattress element.
[0100] According to one embodiment, the first contact surface and the second contact surface include contour structures that correspond to each other and / or at least partially engage with each other. For example, the contour structures can engage with each other like teeth to fix the positional relationship between mattress elements.
[0101] According to one embodiment, the firmness rating of the first mattress element is greater than that of the second mattress element. Conversely, the opposite is also true.
[0102] According to one embodiment, on the first outer surface of the first mattress element and / or the second outer surface of the second mattress element, at least one, and particularly multiple, transverse grooves extending laterally along the mattress are formed between at least one head support area and at least one neck support area. These transverse grooves have T-shaped, trapezoidal, and / or triangular cross-sections. The transverse grooves can be formed, for example, as grooves, ribs, channels, cuts, resections, recesses, notches, and / or cavities extending the full width of the mattress in the transverse direction (the mattress is also referred to as a "combination mattress").
[0103] Generally, at least one transverse groove can be formed in at least one head support area, neck support area, shoulder support area, lumbar support area, and pelvic support area. Typically, the contour structure of individual support areas can be defined and / or defined by the presence or absence of transverse grooves. The transverse grooves in different support areas can differ from each other in geometry, cross-section, depth, size, length, and / or width. This allows for variations and / or harmonization of the hardness levels of the support areas. One or more transverse grooves can have teardrop-shaped, circular, triangular, trapezoidal, rounded, elliptical, oval, or T-shaped cross-sections. Generally, the depth of the transverse groove measured along the vertical axis is approximately 1 to 5 cm, and the width of the transverse groove measured along the longitudinal axis is approximately 1 to 4 cm.
[0104] Alternatively, one or more transverse grooves may be embedded in the mattress material in such a way that they are at least partially covered on the outside by the mattress material.
[0105] According to one embodiment, in at least one pelvic support area, at least one, particularly a plurality of, transverse grooves extending laterally along the mattress are formed on the first outer surface of the first mattress element and / or the second outer surface of the second mattress element, the transverse grooves having a T-shaped, trapezoidal and / or triangular cross-section.
[0106] According to one embodiment, in at least one shoulder support area, at least one, particularly a plurality of, transverse grooves extending laterally along the mattress are formed on the first outer surface of the first mattress element and / or the second outer surface of the second mattress element. These transverse grooves have circular, oval, teardrop, and / or elliptical cross-sections.
[0107] According to one embodiment, in at least one shoulder support area, a plurality of transverse grooves extending laterally along the mattress are formed on the first outer surface of the first mattress element. Each transverse groove has a circular and / or teardrop-shaped cross-section, and the transverse grooves formed in the shoulder support area have the same diameter, cross-section, and / or dimensions. The “dimensions” of the transverse grooves may refer to dimensions (e.g., width) measured along the longitudinal direction of the mattress.
[0108] According to one embodiment, in at least one shoulder support area, a plurality of transverse grooves extending laterally along the mattress are formed on the second outer surface of the second mattress element. Each transverse groove has a circular and / or teardrop-shaped cross-section, and the diameter and / or size of at least some of the transverse grooves in the shoulder support area are different from each other. The diameter, size, width, and / or dimensions of the transverse grooves / slots may gradually decrease in the direction toward the central transverse axis and / or central plane.
[0109] The mattress according to this embodiment preferably has a thickness of at least 18 cm, at least 20 cm, at least 22 cm, at least 24 cm, at least 26 cm, at least 28 cm, at least 30 cm, or at least 32 cm. The packaging described herein has proven particularly suitable for mattresses with the aforementioned thicknesses.
[0110] Alternatively, the mattress according to this embodiment preferably has a width of at least 100 cm, at least 105 cm, at least 110 cm, at least 115 cm, at least 120 cm, at least 125 cm, at least 130 cm, at least 140 cm, at least 150 cm, at least 160 cm, at least 175 cm, at least 180 cm, at least 200 cm, at least 220 cm, at least 240 cm, at least 260 cm, at least 280 cm, or at least 300 cm. The mattress of the above dimensions, after being rolled and / or folded, is particularly convenient to package using the packaging proposed herein, and, where necessary, the fasteners proposed herein.

[0129] Figure 1a shows a mattress 202 placed in package 100, wherein the mattress 202 and package 100 as a whole are indicated by reference numeral 1. Figure 1b shows a cross-sectional view of the mattress 202 and package 100 along line A in Figure 1a.
[0130] The mattress 202 is compressed and hermetically sealed within the packaging 100. For this purpose, the packaging 100 consists of or includes two layers of paper 300 and 301, wherein the first paper layer 300 completely covers the upper side 205 of the mattress 202, and the second paper layer 301 (see FIG. 1b) completely covers the lower side 101 of the mattress 202. The paper layers 300 and 301 extend around the perimeter or ends of the mattress 202, thus forming an overlap 309 at the ends of the mattress 202. Both the first paper layer 300 and the second paper layer 301 include a coating 302 made of a weldable material (see FIG. 1b). The coating 302 is provided on the side of each paper layer 300 and 301 facing the mattress 202. The two paper layers 300 and 301 can be separate sheets of paper placed above and below the mattress 202, respectively. Alternatively, a longer strip of paper can be wrapped around the mattress 202, connecting the paper layer above the mattress 202 to the paper layer below it (e.g., by folding). In this case, the folded or turned-over side of the paper does not need to be welded again. Nevertheless, the weld 303 described below can also be provided here, for example, to enhance the sealing of the packaging 100 to the outside.
[0131] As particularly evident in Figure 1b, the two layers of paper 300 and 301 are welded together. Specifically, a weld 303 is formed in the overlap region 309, which is obtained by welding the coating 302 of the first paper layer 300 and the second paper layer 301. The weld 303 is preferably only located in the overlap region 309. To form the weld 303, for example, a roller, a milling machine, or a punch can be used to press the two layers of paper 300 and 301 and their coating 302 together while heating. Thus, the materials with weldable coatings 302 are welded together to form the weld 303.
[0132] The weld 303 preferably has a width 310 of several centimeters. This ensures that the package 100 is securely and airtightly sealed and maintains this condition over a longer storage period. As shown in Figure 1b, the width 310 extends in a direction parallel to the upper side 205 and lower side 101 of the mattress 202.
[0133] In the packaging 100, the mattress 202 is surrounded by a circumferential weld 303, especially on each end. In other words, the mattress 202 is located in the internal space of the packaging 100, which is situated between two layers of paper 300 and 301 and is completely isolated from the external environment by weld 303 or multiple welds 303. The paper layers 300 and 301 and their coating 302, along with the weld 303, are all airtight structures, thus achieving airtight or sealed isolation between the internal cavity of the packaging 100 containing the mattress 202 and the external environment.
[0134] Mattress 202 is smaller in size within package 100 than in its unpackaged state. In particular, mattress 202 is significantly thinner within package 100, only a fraction of its usual thickness. This can be achieved by compressing mattress 202 before sealing or welding package 100. For example, mattress 202 can be compressed using one or more rollers and / or one or more pressure heads. Package 100 is then sealed while mattress 202 is in a compressed state, thus counteracting the tendency of mattress 202 to spring back to its original shape.
[0135] The interior of the packaging 100, and consequently the interior of the mattress 202, can be under negative pressure. In other words, the mattress 202 can be vacuum-packed or vacuum-sealed. For example, the mattress 202 can be packaged within a vacuum or negative pressure chamber. Alternatively, at least one or more suction pipes 305 (see Figure 1a) can be provided to establish communication between the interior of the packaging 100 containing the mattress 202 and the external environment. Negative pressure can be created by extracting air from this interior. For example, a vacuum pump can be connected to the suction pipe 305 to evacuate the interior, and consequently the mattress 202. The suction pipe 305 is preferably also constructed to be airtight or sealable. For example, the suction pipe 305 can also be compressed and welded by welding tools, such as rollers or pressure heads. For this purpose, the suction pipe 305 is preferably also coated with a weldable material, and preferably with the same material as the coating of the paper layers 300, 301. The coating of the extraction duct 305 is preferably located on its inner side so that an airtight seal can be achieved by welding.
[0136] Figure 2 shows an enlarged view of a corner of the mattress 202 and the packaging 100. Strips of the packaging 100 are torn open, revealing the weldable material coating 302 of the first paper layer 300 facing the mattress 202, as well as the mattress 202 itself. The packaging 100 of the mattress 202, using paper or paper layers 300, 301, allows for easy opening and removal of the packaging 100 without the need for aids or tools. Furthermore, the packaging 100 is largely recyclable and reusable.
[0137] Packaging 100 (e.g., at least one or two paper layers 300, 301) includes printing 304. Printing 304, for example, indicates easy-open locations of packaging 100. For instance, printing 304 may indicate predetermined tear points 307, such as perforated lines or tear strips. Furthermore, printing 304 may contain warnings about not using knives and / or scissors or other sharp objects to open packaging 100. For example, packaging 100 may include statements indicating its easy tearing. This protects the mattress 202 from damage when opening packaging 100 and also reduces the risk of injury to the user when opening packaging 100.
[0138] Figure 3 shows the mattress 202 and package 100 in their rolled-up state, denoted by 1. The mattress 202, together with the package 100, is rolled into a cylindrical shape, with the overlap 309 of the paper layers 300, 301 located and visible at the front end. Conversely, the cylindrical sides of the rolled-up mattress 202 and package 100 are not visible because they are covered by fastener 306. Fastener 306 is constructed, for example, as a paper band. The paper material of this band can be of the same composition as that of the package 100. For example, the same material can be used so that the band also includes a coating 302 made of a weldable material. Alternatively, the band can be made of uncoated paper. This band spans the entire width of the mattress 202 and package 100. In other words, fastener 306 covers the entire cylindrical side of the cylindrical rolled-up mattress 202 and package 100. The fastener 306 thus prevents the mattress 202, along with the packaging 100, from accidentally unwinding and keeps it in a rolled-up state.
[0139] Figure 4 shows the mattress 202, together with packaging 100, and especially with fasteners 306, placed in an additional outer packaging 308. The outer packaging 308 is, for example, a cardboard box, such as a shipping box. Therefore, the mattress 202, indicated by reference numeral 1 in Figure 4, together with packaging 100, is in a packaged state ready for direct shipment and can directly enter the mail order process.
[0140] Figures 5a and 5b illustrate examples of removing or detaching the fastener 306 from the mattress 202 along with the packaging 100. Specifically, the fastener 306 includes printing 304, which substantially corresponds to the printing 304 on the packaging 100 described above. The printing 304 includes an indication of a predetermined tear point 307 (e.g., a perforated line or tear strip) provided in the fastener 306. The printing 304 thus indicates that the fastener 306 can be torn directly along the predetermined tear point 307. Furthermore, the printing 304 may include a warning that the fastener 306 should not be cut with sharp tools such as knives or scissors. Using such sharp tools could damage the mattress 202, its packaging 100, and in the worst case, injure the user. In Figure 5b, the fastener 306, which consists of paper straps, has been partially opened, revealing the assembly 1 consisting of the mattress 202 and the packaging 100 placed therein. According to this disclosure, fastener 306, like packaging 100, is therefore largely recyclable and reusable.
[0141] The following figures illustrate the mattress 202 and its mattress cover 204 in more detail. The packaging 100 (having at least one paper layer 300, 301) according to this disclosure is specifically designed to package the mattress 202 together with the mattress cover 204 described below. Since the packaging 100 must reliably keep the mattress 202 together with the mattress cover 204 (if necessary, vacuum-packed mattress 202 and cover 204) compressed, rolled, and / or folded, and maintain it in a compressed state, the characteristics of the mattress 202 together with the mattress cover 204 are closely related to the packaging 100. To ensure that the functions described herein are achieved over extended periods and under different environmental conditions, the two are therefore preferably closely matched.
[0142] Figure 6 shows a perspective view of a mattress cover 204 according to an exemplary embodiment. Figure 7 shows a simplified plan sectional view of the outer side of the mattress cover 204 shown in Figure 6. Figure 8 shows a schematic cross-sectional view of the covering fabric of the mattress cover 204 shown in Figures 6 and 7.
[0143] Referring to Figure 6, an exemplary view is shown of a mattress cover 204 (or mattress protector 204) stretched over a mattress 202. The mattress cover 204 forms a first lying surface on the upper side 205 of the mattress and optionally forms a second lying surface for the user on the opposite lower side 101.
[0144] The entire perimeter of the mattress cover 204 is formed of the same covering fabric 5, thereby allowing the front sub-surfaces of the sides, such as the transverse surface 6 and the longitudinal surface 7, to optionally transition seamlessly with the upper side 205 and the lower side 101. However, in other designs, the surfaces of the covering fabric 5 may also be separated by stitching and, where necessary, by piping.
[0145] For inserting and removing the mattress 202, a circumferential closure 206 (in the form of a zipper) is sewn into the transverse surface 6 and longitudinal surface 7 of the mattress cover 204 (or mattress protector 204). Furthermore, multiple handles 210 are provided on the transverse longitudinal surface 7 to lift the mattress 202 covered by the mattress cover 204 (or mattress protector 204); only one handle 210 is shown in the example.
[0146] As shown in section X of Figure 6 (representing the entire surface of the mattress cover 204 (or mattress protector 204)) and in conjunction with Figures 7 and 8, the overlay fabric 5 is formed from the weft-knitted fabric 10 (such as 3D weft-knitted fabric) all the way to its outer side 11.
[0147] The covering fabric 5 comprises a honeycomb-like mesh structure, which presents regular, finely spaced open recesses 12 on the outer side. The external cross-section of the recesses 12 is preferably circular, rounded, elliptical, and / or oval, and in the unstretched state, its width may be, for example, 2 mm to 4 mm, and its length may be approximately 3 mm to 5 mm.
[0148] Material strips 13, located between the recesses 12 and formed by weft-knitted fabric 10, are arranged in an interlaced and regular manner, and their widths can be designed to be at least approximately equal.
[0149] The overlay fabric 5 exists as a double or triple weft-knitted fabric, wherein the upper layer 14 forms the outer side 11, the optional middle layer 15 forms the weft-knitted fabric 10 and is woven together with the upper layer 14, and the inner / lower layer 16 is woven together with the upper layer 14 and / or the optional middle layer 15.
[0150] The upper layer 14 may contain monofilament yarns (such as smooth monofilament yarns) or textured polyfilament yarns (such as twisted polyfilament yarns). Similarly, the lower layer 16 may also contain monofilament yarns (such as smooth monofilament yarns) or polyfilament yarns (such as textured, twisted polyfilament yarns). Likewise, the middle layer 15 may also be at least partially composed of monofilament yarns or polyfilament yarns.
[0151] One or more of the upper layer 14, middle layer 15, and lower layer 16 may also contain natural fibers, and / or be at least partially composed of natural fibers, as described above. Natural fibers may be, for example, animal hair fibers, wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, flax fibers, wood fibers, viscose fibers, sesame fibers, silk fibers, plant fibers, or combinations thereof. Compared to synthetic fibers, such natural fibers may exhibit better performance in terms of sustainability, odor neutrality, skin compatibility, durability, and / or toughness.
[0152] The outer side 11 of the upper layer 14 also includes a finely knitted structure 17, giving the surface a soft touch.
[0153] In terms of thickness, in a preferred embodiment, the thickness of the upper layer 14 is designed to account for at least 70% to 80% of the total thickness of the overlay fabric 5 in order to maximize the advantages of the weft-knitted fabric 10 in terms of microclimate.
[0154] To achieve maximum air circulation and optimal moisture removal to the outside 11, the honeycomb recesses 12 extend substantially through the thickness of the upper layer 14 and the middle layer 15 to the adjacent lower layer 16, thereby giving the covering fabric high flexibility and elasticity in the width direction due to these recesses 12. The elasticity in the height direction provides softness, which can be set by the filling material of the middle layer 14 according to the desired softness.
[0155] Needless to say, the overlay fabric 5 can be manufactured using all known spaced knitting and finishing methods, depending on the application, such as washing, bleaching, and pre-shrinking processes performed after the knitting process. Optionally, the mattress cover 204 may be at least partially coated, rubberized, and / or latexed to prevent moisture penetration.
[0156] Figures 9a to 9f respectively illustrate various parts of the mattress 202 according to an exemplary embodiment. Figure 9a shows a top view of the first mattress element 2 of the mattress 202. Figure 9b shows a schematic cross-sectional view of the first mattress element 2 in Figure 9a, wherein the first mattress element 2 in Figures 9a and 9b is shown without the transverse grooves. Figure 9c shows... Figure 9a Figure 9b shows a side view of the first mattress element 2, which has multiple transverse grooves. Figure 9d shows a top view of the second mattress element 3 according to an embodiment of the present disclosure. Figure 9e shows a cross-sectional view of the second mattress element 3 shown in Figure 9d (excluding the transverse grooves). Figure 9f shows a mattress 202 according to an embodiment of the present disclosure. The mattress 202 of Figure 9f includes the first mattress element 2 described with reference to Figures 9a to 9c, and the second mattress element 3 described with reference to Figures 9d and 9e.
[0157] The first mattress element 2 includes a first outer surface 21 and a first contact surface 22 disposed opposite thereto. The first outer surface 21 is configured as a first lying surface for a user to lie on. The second mattress element 3 includes a second outer surface 31 and a second contact surface 32 disposed opposite thereto. The second outer surface 31 may optionally be configured as a second lying surface for a user to lie on. The first and second mattress elements 2 and 3 are arranged in a stacked manner, such that the first and second contact surfaces 22 and 32 are at least partially in contact with each other.
[0158] To achieve ergonomic and comfortable support, the two mattress elements 2, 3 and / or mattress 202 each include multiple support zones 41, 42, 43, 44, and 45. These support zones 41, 42, 43, 44, and 45 may include a head support zone 41, a neck support zone 42, a shoulder support zone 43, a lumbar support zone 44, and a pelvic support zone 45.
[0159] Mattress 202 has a longitudinal direction x (or longitudinal axis x) extending parallel to the longitudinal edge of the mattress, a transverse direction z (or transverse axis z) extending parallel to the transverse edge of the mattress, and a vertical axis y that is transverse to and / or orthogonal to the longitudinal direction x and the transverse direction z. The length of mattress 202 is measured along the longitudinal direction, the width is measured along the transverse direction z, and the thickness or height is measured along the vertical axis y. The length of mattress 202 may be greater than or equal to its width. The first mattress element 2 and the second mattress element 3 may have the same or different heights and / or thicknesses.
[0160] Furthermore, mattress 202 includes a central transverse axis 50 and / or a central transverse plane 50, which is parallel to the transverse direction z and located at the center between two opposite ends in the longitudinal direction x. The central transverse axis (or plane) 50 divides the first mattress element 2 into a first half 2a and a second half 2b. Similarly, the central transverse plane (or transverse axis) 50 divides the second mattress element 3 into a first half 3a and a second half 3b.
[0161] Each half 2a, 2b, 3a, 3b of the first and second mattress elements 2 and 3 includes support areas 41, 42, 43, 44, and 45. The support areas 41, 42, 43, 44, and 45 are arranged symmetrically with respect to the central transverse axis 50. Each support area 41, 42, 43, 44, and 45 differs from each other at least partially in terms of firmness grade, firmness, compressive firmness, and / or elasticity. For example, each support area 41, 42, 43, 44, and 45 may have at least partially different contours, profiles, and / or structures, such as transverse grooves 51, 52, 53, and 54 formed in each support area. The transverse grooves 51, 52, 53, and 54 may be formed on the first and / or second outer surfaces 21 and 31 and extend transversely across the full width of the mattress 202 in the transverse direction z. To adjust the hardness of each support zone 41, 42, 43, 44, 45, the contours and / or the transverse grooves 51, 52, 53, 54 in each support zone may differ from one another in terms of their cross-section, geometry, shape, number, depth measured along the vertical axis y, and thickness or size measured along the longitudinal direction x.
[0162] As shown in Figure 9c, the first mattress element 2 has a first transverse groove 51 in each of its two halves 2a and 2b to separate the head support area 41 from the neck support area 42. The first transverse groove 51 has a T-shaped cross-section.
[0163] Furthermore, the first mattress element 2 has five second transverse grooves 52 in each of the shoulder support areas 43 of the two halves 2a and 2b, each having a circular, oval, elliptical, and / or teardrop-shaped cross-section. The five second transverse grooves 52 in the shoulder support areas 43 of the two symmetrical halves 2a and 2b of the first mattress element 2 have the same geometry, width, dimensions, size, thickness, and / or diameter. The neck support area 42 of the first mattress element 2 is separated from its adjacent shoulder support area 43 by a second transverse groove 52. Similarly, along the direction towards the central transverse axis 50, each shoulder support area 43 is also separated from its adjacent lumbar support area 44 by a second transverse groove 52. In addition, each lumbar support area 44 is separated from its adjacent pelvic support area 45 by a third transverse groove 53. Three third transverse grooves 53 are formed in two adjacent pelvic support areas 45 located at the central transverse axis 50, each having a T-shaped and / or triangular cross-section. The three third transverse grooves 53 have the same geometry, width, dimensions, size, thickness, and / or diameter. The middle third transverse groove 53 may extend along the central transverse plane 50 and define the boundary between the first half 2a and the second half 2b.
[0164] As shown in Figure 9f, at least one further transverse groove 54 may be formed in each waist-curved support region 44, which may, for example, contain a circular and / or oval cross-section.
[0165] As shown in Figure 9f, the first contact surface 22 of the first mattress element 2 is not contoured, outlined, or structured. In other words, the first contact surface 22 is completely planar. However, alternatively, a contour may be formed in at least a portion of the first contact surface 22. The cross-section of the transverse groove conceivable here may include circular, oval, elliptical, triangular, square, polygonal, trapezoidal, etc., as described above and below.
[0166] As shown in Figure 9f, the second mattress element 3 has a first transverse groove (cross-groove) 61 in each of the two halves 3a and 3b to separate the head support area 41 from the neck support area 42. The configuration of the first transverse groove 61 is similar to that of the first transverse groove 51 of the first mattress element 2, and has a T-shaped cross-section. In addition, the second mattress element 3 has five second transverse grooves 62 in each of the shoulder support areas 43 of the two halves 3a and 3b, each with a circular, oval, elliptical, and / or teardrop-shaped cross-section. The configuration of the second transverse grooves 62 of the second mattress element 3 is similar to that of the second transverse groove 52 of the first mattress element 2, but the width, dimensions, size, thickness, and / or diameter of the five second transverse grooves 62 in the shoulder support areas 43 of the two halves 3a and 3b of the second mattress element 3 decrease continuously in the direction towards the central transverse axis 50. The neck support area 42 of the second mattress element 3 is separated from its adjacent shoulder support area 43 by a second transverse groove 62. Similarly, each shoulder support area 43 is separated from its adjacent lumbar support area 44 by a second transverse groove 62 along the direction toward the central transverse axis 50. Furthermore, each lumbar support area 44 is separated from its adjacent pelvic support area 45 by a third transverse groove 63. Three third transverse grooves 63 are formed in two adjacent pelvic support areas 45 located at the central transverse axis 50, with a configuration similar to the third transverse groove 53 of the first mattress element 2, and each having a T-shaped and / or triangular cross-section. The three third transverse grooves 63 have the same geometry, width, dimensions, size, thickness, and / or diameter. The middle one of the three third transverse grooves 63 may extend along the central transverse plane 50 and define the boundary between the first half 3a and the second half 3b. In addition, analogous to the further transverse groove 54 of the first mattress element, at least one further transverse groove 64 may also be formed in each lumbar support area 44 of the second mattress element 3, for example having a circular and / or oval cross-section.
[0167] The transverse grooves 61, 62, 63, and 64 of the second mattress element 3 are opposite to the transverse grooves 51, 52, 53, and 54 of the first mattress element 2 and are formed on the second outer surface 31 of the second mattress element 3. Furthermore, the two halves 2a and 2b of the first mattress element 2 and the two halves 3a and 3b of the second mattress element 3 are configured in a completely mirror-symmetrical manner with respect to the central transverse axis 50 or the central transverse plane 50.
[0168] As shown in Figure 9f, the second contact surface 32 of the second mattress element 3 has a contour structure 33, which includes multiple transverse grooves 34. In the example, the transverse grooves 34 are shown in a rectangular cross-section, but any other cross-section may be used.
[0169] The contour structure 33 may also be configured as a waveform with multiple peaks and troughs. Alternatively, the contour structure 33 or other contours may be embedded in the first contact surface 22 of the first mattress element 2. Contours and / or transverse grooves may also be embedded simultaneously in both contact surfaces, so that they at least partially engage with each other.
[0170] Examples of transverse grooves for the first outer surface 21, the second outer surface 31, the first contact surface 22, and / or the second contact surface 32 are shown in the following figures.
[0171] Figures 10 to 13 illustrate examples of transverse grooves in a mattress 202 according to an exemplary embodiment. In particular, longitudinal cross-sections through each mattress 202 are shown.
[0172] The mattress 202 in Figure 10 is divided into three parts and includes three mattress elements 2, 3, and 3'. In contrast, the mattresses 202 in Figures 11 to 13 include only two mattress elements 2 and 3. However, any number of mattress elements can be provided.
[0173] The transverse grooves and / or contour structures shown in Figures 10 to 13 are for illustrative purposes only and are arranged on the contact or outer surfaces of the illustrated mattress elements 2, 3, 3'. However, the transverse grooves and / or contour structures may also be arranged on any other surface of the mattress 202.
[0174] In the example of Figure 10, the first mattress element 2 does not include any contour or transverse groove. The second mattress element 3 includes a trapezoidal transverse groove 500 on the contact surface 32 and a rectangular transverse groove 600 on the side or surface opposite to the contact surface 32, the transverse groove 600 being recessed and spaced from the surface and embedded and / or inserted into the interior of the second mattress element 3. Another mattress element 3' without contour forms another outer surface of the mattress 202.
[0175] In the example shown in Figure 11, the first mattress element 2 includes a transverse groove 500 with a circular cross-section on its outer surface 21 and a transverse groove 550 with a rectangular, trapezoidal, or triangular cross-section on its contact surface 22. The second mattress element 3 has a transverse groove 600 with a circular cross-section only on its outer surface 31, while its contact surface 32 is not contoured.
[0176] In Figure 12, the first mattress element 2 includes pod-shaped transverse grooves 500 introduced into the first mattress element 2 through cutouts 501 on the first contact surface 22, such that the transverse grooves 500 are closer to the first outer surface 21 relative to the first contact surface 22. Similar transverse grooves 600 are introduced into the second mattress element 3 through cutouts 601 on the second contact surface 32. The transverse grooves 600 may be boomerang-shaped, hanger-shaped, and / or triangular. Furthermore, additional transverse grooves 603 with circular cross-sections are embedded in the second mattress element 3. The second outer surface 31 of the second mattress element 3 is unprofiled.
[0177] In the example shown in Figure 13, the first mattress element 2 and the second mattress element 3 have corresponding contours and / or transverse grooves 500 and 600 on their contact surfaces 22 and 32, and engage with each other at least partially in a toothed manner. The outer surfaces 21 and 31 of the two mattress elements 2 and 3 are not contoured.
[0178] It should also be noted that "comprising" and "having" do not exclude the presence of other elements, and "a" does not exclude multiple elements. Furthermore, it should be noted that features described with reference to any of the exemplary embodiments described above may also be used in combination with features of other exemplary embodiments described above. Reference numerals in the claims should not be considered limiting.
