Description

Technical Field

[0001] This utility model relates to a seamless (sewn) quilt with no stitches around the edges, belonging to the field of home furnishing product technology. Background Technology

[0002] Quilts are a common household product. Typically, quilts use stitching to secure the fabric and inner filling. Over time, this inevitably leads to issues such as enlarged needle holes causing the filling to leak out or dust to enter, as well as worn and broken stitches. To improve user experience and lifespan, the industry has developed seamless quilts, where the quilt cover and inner filling are fixed together using adhesives, fusion welding, ultrasonic welding, or other seamless (sewing) methods. For example, Chinese patent CN119453709A, entitled "A Seamless Quilt, Seamless Quilt Manufacturing Process and Device," discloses a seamless quilt where the upper and lower quilt covers are fixed through the filling material. However, the edges of this seamless quilt are relatively hard due to the bonded structure of the upper and lower quilt covers. When sleeping, the neck or other parts of the body may come into contact with these hard edges, easily causing discomfort. Therefore, there is an urgent need in this technical field for a seamless (sewing) quilt with no stitches and edging that overcomes these defects and provides a comfortable feel for the body parts in contact with the edges of the quilt during sleep. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of how to obtain a seamless (sewn) quilt with no stitches and no edging that makes the user feel more comfortable while sleeping.

[0004] To address the aforementioned problems, the present invention provides a seamless quilt with no visible traces. The seamless quilt comprises a first surface layer, a second surface layer, and a core material, with the core material disposed between the first surface layer and the second surface layer. The edge of the seamless quilt is provided with an edging, which includes an edge portion of the first surface layer. The edge portion of the first surface layer is folded over and wrapped around the outside of the second surface layer, and is connected and fixed to the second surface layer to form the edging. A gap without adhesive is provided between the outermost edge of the edging and the edge of the core material.

[0005] Preferably, the first and second surface layers are provided with a plurality of corresponding predetermined areas, and the first and second surface layers pass through the core material and are connected and fixed in the predetermined areas; or the first and second surface layers are connected and fixed to the core material in the predetermined areas.

[0006] Preferably, the connection between the edge portion one and the surface layer two is located at the edge of the core material.

[0007] Preferably, the edging is provided on the four edges of the seamless lining, and the edging includes a U-shaped structure containing a gap formed by the edge portion of the surface layer; the continuous bottom edge of the U-shaped structure is the outermost edge of the seamless lining.

[0008] Preferably, the length / width of the first surface layer is greater than the length / width of the second surface layer, and the length / width of the second surface layer is greater than the length / width of the core material; the edge of the second surface layer is folded over to wrap the edge of the core material, and the edge of the first surface layer is folded over to wrap the edges of the second surface layer and the core material.

[0009] Preferably, the length / width of the first surface layer is greater than the length / width of the second surface layer, and the length / width of the second surface layer is not less than the length / width of the core material; the edge of the second surface layer slightly extends beyond the edge of the core material, and the edge of the first surface layer is folded over to wrap around the edges of the second surface layer and the core material.

[0010] Preferably, the edges of the first and second surface layers are continuously or intermittently connected and fixed to wrap the core material.

[0011] Preferably, the shape of the predetermined area includes a circle, annulus, dot, strip, or petal shape.

[0012] Preferably, the core material has a through hole in the middle corresponding to the predetermined area, and the first surface layer and the second surface layer pass through the through hole in the predetermined area to form a connecting part, which is used to limit the core material.

[0013] Preferably, the core material is a prefabricated integral core material, the integral core material is a composite structure, the composite structure includes multiple composite layers, the multiple composite layers are layers with different elasticity, or different air permeability, or different heat retention capacity, or different fluffiness; the integral core material is a zoned heterogeneous structure, the integral core material has several functional zones with different regional performance.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model discloses a seamless quilt manufactured by an adhesive bonding process. By setting a predetermined area, the upper and lower layers of the quilt are connected and fixed through the internal core material in the predetermined area, thereby limiting the position of the core material and preventing it from moving. It is especially suitable for prefabricated integrated core materials, which are less prone to movement.

[0016] Furthermore, by setting the edge of the seamless quilt as the side of the upper or lower layer to form a binding after several folds, and using a flexible edge formed by a continuous surface layer, the shortcomings of existing seamless quilts, where the edges of the upper and lower quilts are directly glued together, resulting in a hard feel and causing discomfort when the neck or other parts of the body come into contact with the hard edge, are overcome. This reduces the pressure on the neck and other parts of the body caused by the edge of the seamless quilt, and provides a seamless quilt product form with a softer and more comfortable user experience.

[0034] Alternatively, the length / width of the first surface layer 200 is greater than the length / width of the second surface layer 100, and the length / width of the second surface layer 100 is not less than the length / width of the core material 300; the edge of the second surface layer 100 slightly extends beyond the edge of the core material 300, and the edge of the first surface layer 200 is folded over to wrap around the edges of the second surface layer 100 and the core material 300.

[0037] The core material is a prefabricated integrated core material, which is a composite structure.

The integrated core material is a zoned heterogeneous structure, which has several functional zones with different regional performance.

[0038] Example

[0039] like Figure 1-8 This utility model provides a seamless quilt with no visible seams, including a first surface layer 200, a second surface layer 100, and a core material 300 wrapped between the second surface layer 100 and the first surface layer 200; a plurality of predetermined areas 400 coated with adhesive are provided in the middle portion of the second surface layer 100 and the first surface layer 200; the middle portion of the second surface layer 100 and the first surface layer 200 passes through the core material 300 in these predetermined areas 400 and is bonded and fixed together to form a seamless quilt with a three-layer structure;

[0040] The core material 300 has a through hole in the middle part corresponding to the predetermined area 400. The second surface layer 100 and the first surface layer 200 pass through the through hole in the predetermined area 400 and are connected and fixed to form a connecting part 500. The connecting part 500 is used to limit the movement of the core material 300.

[0041] In one embodiment, such as Figure 4The length of surface layer 200 is greater than the length of surface layer 100, and the length of surface layer 100 is greater than the length of core material 300. The edges of surface layer 100 and surface layer 200 are folded to form U-shaped folded edges 600. The edge of surface layer 100 wraps around the edge of core material 300 through the U-shaped folded edges 600, and the edge of surface layer 100 is bonded to the edge of core material 300. The inner surface of the edge of surface layer 200 wraps around the outer surface of the edge of surface layer 100 through the U-shaped folded edges 600 and is bonded and fixed. The U-shaped folded edges 600 formed by surface layer 200 form a seamless edge area. There is a gap between the bottom of the U-shape formed by surface layer 200 and the edge of core material, and there is no adhesive in the gap.

[0042] Fixed connection areas are respectively provided on the inner edge of surface layer 200, the inner and outer edges of surface layer 100, and the edge of core material 300. Adhesive is provided on the fixed connection areas, and the adhesive includes silicone.

[0043] Because the edge of the surface layer 200 is formed by folding a U-shaped fold 600, when in use, the user's body comes into contact with a soft edge formed by the seamless, non-adhesive part of the surface layer 200, which provides a more comfortable contact experience.

[0044] In another embodiment, such as Figure 5 As shown, the length of surface layer 200 is greater than the length of surface layer 100, and the length of surface layer 100 is slightly greater than the length of core material 300. Surface layer 100 covers one side of core material 300, and the side of surface layer 100 slightly exceeds the edge of core material 300. The edge of surface layer 200 is folded twice towards the center of the seamless material to form a figure-9 shaped edging 700, so that part of the outer surface of surface layer 200 is fixed to the outer surface of the edge of surface layer 100. The edge of surface layer 100 is bonded to the edge of core material 300. The outer surface of the edge of surface layer 200 is wrapped around the outer surface of the edge of surface layer 100 by the figure-9 shaped edging 700 and bonded and fixed. The figure-9 shaped edging 700 formed by surface layer 200 forms the edge area of ​​the seamless material. There is a gap between the edge of the edging formed by the figure-9 shaped edging 700 and the edge of the core material, and there is no adhesive in the gap.

[0045] Fixed connection areas are respectively provided on the outer edge of surface layer 200, the inner and outer edges of surface layer 100, and the edge of core material 300. Adhesives are provided on the fixed connection areas, including silicone.

[0046] Because the edge of the surface layer 200 is folded to form a edging, when in use, the user's body comes into contact with the soft, seamless edging formed by the surface layer 200 without any adhesive, which provides a more comfortable contact experience.

[0047] For example, the core material 300 can be a single sheet of pre-made insulation medium, such as a latex sheet, a polyester fiber sheet, or a composite material sheet. The edges of the first surface layer 200 and the second surface layer 1 can be intermittently fixedly connected, which also serves to wrap the core material.

[0048] In a further embodiment, the shape of the predetermined area 400 can be circular, annular, dotted, elongated, or petal-shaped, etc. Core material should be avoided in the predetermined area 400; that is, the core material 300 should have through holes corresponding to the predetermined area 400, so that the second surface layer 100 and the first surface layer 200 can pass through the through holes to connect and fix them to form a connecting portion 500 in the predetermined area 400. See [link to previous embodiment]. Figure 2 The connecting part 500 can be used to limit the core material 300, and the predetermined area 400 can be arrayed. For the integral core material 300, holes should be pre-drilled in the predetermined area 400, and then the second surface layer 100 and the first surface layer 200 should be connected in the predetermined area 400 to form the connecting part 500. The limiting and fixing effect is better, and the integral core material is less likely to move.

[0049] In a further implementation, see Figure 6 The integrated core material 300 is a prefabricated component with a composite structure, including a double-layer composite. One layer is a weakly elastic layer 300-1, and the other is an elastic layer 300-2. The elasticity of the weakly elastic layer 300-1 is less than that of the elastic layer 300-2. This integrated core material is used behind a seamless comforter, allowing users to choose which side to face while sleeping, as the two sides provide different sleeping experiences. In addition to elasticity, it can also be designed with layered structures with different breathability, different warmth retention, and different loft to provide users with different sleeping experiences. Similarly, it can also be designed with a multi-layered composite structure.

[0050] In another implementation, see Figure 7 The integrated core material 300 is a prefabricated component with a partitioned, heterogeneous structure. Different insulation capabilities are set in different areas along the length of the core material. For example, stronger insulation material is set in the abdomen area, while ordinary insulation material is set in other areas. Thus, the abdomen area is insulation partition 300-3. Similarly, insulation partitions can be set in areas corresponding to the shoulders, ankles, knees, etc.

[0051] Furthermore, see Figure 8The integrated core material 300 is a prefabricated component with a partitioned, irregular structure. Functional partitions 300-4 are set in special areas. In addition to the warmth partition, the functional partition 300-4 can also be set as a breathable partition, located in the fan-shaped area between the two shoulders. When the user covers their mouth and nose, they can still breathe freely, bringing a new user experience. Of course, weight partitions can also be set on the sides of the body to provide downward pressure from the sides and help prevent unconsciously rolling up the blanket while sleeping.

[0052] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from this application, and these improvements and additions should also be considered within the scope of protection of this application. Any modifications, alterations, and equivalent variations made by those skilled in the art based on the disclosed technical content without departing from the content and scope of this application are equivalent embodiments of this application. Furthermore, any equivalent changes, alterations, and variations made to the above embodiments based on the essential technology of this application still fall within the scope of the technical solution of this application.
