Description

Technical Field

[0001] This utility model relates to a seamless (sewn) quilt without any traces, 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 (sewn) quilts. In these quilts, the cover and inner filling are fixed together using seamless (sewing) methods such as adhesive bonding, welding, or ultrasonic welding. For example, Chinese patent CN202775408U, entitled "A Seamless Embossed Quilt," provides a seamless quilt. However, the top and bottom layers are only fixed to the filling, leaving the remaining filling material outside the top and bottom layers without proper support, making it prone to shifting. For example, a Chinese patent, patent number CN119453709A, entitled "A seamless quilt, a seamless quilt manufacturing process and a manufacturing apparatus", discloses a seamless quilt in which the upper and lower quilt surfaces are fixed through a core material. Because the edges of this seamless quilt are bonded together with the upper and lower quilt surfaces, they feel relatively hard. When the user sleeps, the neck or other parts of the body come into contact with the hard edges of the seamless quilt, which can easily cause discomfort. Therefore, there is an urgent need in this technical field for a seamless (sewn) quilt that can overcome the above defects and provide a comfortable sleeping experience for the user. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of how to obtain a wireless, seamless (sewn) quilt that provides a comfortable sleeping experience for the user.

[0004] To address the aforementioned problems, the present invention provides a seamless quilt with no traces, comprising an upper layer, a lower layer, and a core material disposed between the upper and lower layers; the upper and lower layers have a plurality of corresponding predetermined areas, and the upper and lower layers are connected and fixed through the core material at the predetermined areas; at least one side of the edge of the seamless quilt is formed by folding the same quilt surface to form the upper and lower layers at the side edge.

[0005] Preferably, the edge of the seamless quilt corresponding to the user's head is formed by folding the same quilt surface to form the upper and lower layers of the edge; the two sides of the seamless quilt along the direction of the user's body are formed by connecting the edges of the upper and lower layers.

[0006] Preferably, the edge of the seamless cover corresponding to the user's foot is formed by connecting the edges of the upper and lower layers.

[0007] Preferably, the edges of the upper layer and the lower layer are intermittently fixedly connected to wrap the core material.

[0008] Preferably, the shape of the predetermined area includes a circle, annulus, dot, strip, or petal shape, etc.

[0009] Preferably, the core material has a through hole corresponding to the predetermined area, and the upper layer and the lower layer are connected and fixed through the through hole in the predetermined area to form a connecting part, which is used to limit the core material.

[0010] Preferably, the core material is a prefabricated integral core material.

[0011] Preferably, the integral core material is configured as a composite structure, and the composite structure includes multiple composite layers.

[0012] Preferably, the multi-layered composite layer is configured as layers with different elasticity, different breathability, different heat retention capacity, or different loft.

[0013] Preferably, the integral core material is configured with a partitioned heterogeneous structure, and the integral core material has several functional partitions 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] By setting the seamless edge corresponding to the user's head to be formed by folding the same quilt surface to create the upper and lower quilt surfaces at the edge, the defect of existing seamless quilts, where the upper and lower quilt surfaces are bonded 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, is overcome. This provides a seamless quilt product form with a softer and more comfortable user experience. Attached Figure Description

Furthermore, the various implementations of the embodiments described herein are complementary rather than purely alternating, unless otherwise stated. In other words, implementations from one embodiment can be freely combined with implementations from other embodiments, as will readily be apparent to those skilled in the art, unless these implementations are stated to be used only as substitutions.

Therefore, they should not be construed as limitations on this application.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] See Figures 1-8 This application provides a seamless three-layer fabric, including an upper layer 100, a lower layer 200, and a core material 300 wrapped between the upper layer 100 and the lower layer 200. By providing a plurality of predetermined areas 400 coated with adhesive on the upper layer 100 and the lower layer 200, the upper layer 100 and the lower layer 200 are bonded together through the core material 300 in these predetermined areas 400, forming a seamless three-layer fabric.

[0031] The core material 300 is provided with a through hole corresponding to the predetermined area 400. The upper layer 100 and the lower 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. At least one side of the edge of the seamless quilt is folded over the same quilt surface to form the upper layer 100 and the lower layer 200 at the side edge.

[0032] In one embodiment, such as Figure 7 The upper and lower covers are made of the same piece of fabric, which is folded in half to form the upper layer 100 and the lower layer 200 of the seamless quilt; the edge of the seamless quilt corresponding to the user's head is a piece of quilt cover folded over to form the upper layer 100 and the lower layer 200 of the seamless quilt at that location, and this edge area is set as the head edge area 230.

[0033] The head edge area 230 includes an upper layer 100, a lower layer 200 and a core material 300. Since the upper layer 100 and the lower layer 200 are not bonded together and are made of the same continuous fabric, the user's head and neck come into contact with a soft, seamless edge, providing a more comfortable contact experience.

[0034] like Figure 3As shown, in this embodiment, a predetermined area 400 in the central region of the lower layer 200 is set as a first adhesive application area 210; a second adhesive application area 220 is set on both sides of the lower layer 200 along the direction of the user's body, and the second adhesive application area 220 is also set on the edge of the lower layer 200 at the user's feet; the upper layer 100 passes through a preset through hole on the core material 300 and is bonded to the lower layer 200 at the first adhesive application area 210 and the second adhesive application area 220. That is, the upper layer 100 and the lower layer 200 are bonded together at the edges corresponding to the left and right sides of the user's body and the edges corresponding to the user's feet; the central regions of the upper layer 100 and the lower layer 200 are bonded together through the preset through hole on the core material 300, thereby restricting the movement of the core material 300; it is seamlessly enclosed on all sides, covering the entire core material 300.

[0035] In another embodiment, such as Figure 8 The seamless lower layer 200 is longer than the upper layer 100, the upper and lower layers are the same width, and a core material 300 is provided between the upper and lower layers; the upper and lower layers are aligned in the width direction and the two side edges are bonded together; the lower layer 200 is folded to form a seamless head edge area 230 corresponding to the user's head; the part of the lower layer 200 folded above the core material 300 is then bonded to the upper layer 200.

[0036] A first adhesive application area 210 is provided in the predetermined area 400 of the central region of the lower layer 200. A second adhesive application area 220 is provided along the two edges of the lower layer 200 below the core material 300 in the direction of the user's body. The second adhesive application area 220 is also provided at the edge of the lower layer 200 near the user's feet. The upper layer 100 passes through a pre-set through-hole in the core material 300 and is bonded to the lower layer 200 at the first adhesive application area 210 and the second adhesive application area 220. That is, the upper layer 100 and the lower layer 200 are bonded together at the edges corresponding to the left and right sides of the user's body and the edges corresponding to the user's feet. The head edge area 230 is simply formed by folding the lower layer 200 over the core material 300 in the middle. Since the lower layer 200 here is a continuous piece of fabric, the user's head and neck come into contact with a soft, seamless edge during use, providing a more comfortable contact experience.

[0037] For example, the core material 300 can be an insulating medium that is filled between the upper and lower layers, such as common down, silk, wool, cotton, or fibers; or it can be a whole sheet of core material pre-made from the insulating medium, such as a latex sheet, polyester fiber sheet, or a mixed material sheet. For non-integral core materials, the edges of the upper and lower layers should be continuously and fixedly connected to enclose the core material; while for integral core materials, the edges of the upper and lower layers can be intermittently and fixedly connected, which can also serve to enclose the core material.

[0038] 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 be left empty corresponding to the predetermined area 400, so that the upper layer 100 and the lower layer 200 can pass through the empty space to connect and fix together to form a connecting portion 500. See [reference needed]. Figure 2 The connecting portion 500 can be used to limit the core material 300, and the predetermined area 400 can be arrayed. See [reference needed]. Figure 3 This forms multiple interconnecting portions 500 arranged in an array to limit the core material 300. For post-filled core material 300, the predetermined area 400 is naturally left empty. The upper layer 100 and the lower layer 200 can first form interconnecting portions 500 in the predetermined area 400 before filling the core material 300. For integral core material 300, holes should be pre-drilled in the predetermined area 400 before connecting the upper layer 100 and the lower layer 200 in the predetermined area 400 to form interconnecting portions 500. This results in better limiting and fixing effect, and the integral core material is less likely to move.

[0039] Of course, the connection and fixing methods between the upper layer 100 and the lower layer 200 include, but are not limited to, adhesive bonding, fusion welding, and ultrasonic welding. Taking adhesive bonding as an example, see... Figure 3 A first adhesive application area 210 is provided on the inner side of the lower layer 200 facing the upper layer 100 in the predetermined area 400, and the upper layer 100 and the lower layer 200 are glued and fixed in the predetermined area 400 including the first adhesive application area 210.

[0040] For example, the upper layer 100 and the lower layer 200 are made of conventional fabric, and the edges of the upper layer 100 and the lower layer 200 are seamlessly connected, see [reference]. Figure 1 The lower layer 200 has a second adhesive application area 220 on its inner side facing the upper layer 100. The edges of the upper layer 100 and the lower layer 200 are glued and fixed in the second adhesive application area 220. The fixed position of the edges of the upper layer 100 and the lower layer 200 is not limited to being close to the edge, but can also be fixed around the edge.

[0041] In a further implementation, see Figure 4The 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.

[0042] In another implementation, see Figure 5 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.

[0043] Furthermore, see Figure 6 The 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.

[0044] 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.
