Description

Technical Field

[0001] This utility model relates to a lace-trimmed, seamless (sewn) quilt, 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 device," 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 made by bonding the upper and lower quilt surfaces together, 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 make the human body parts that come into contact with the edges of the quilt feel comfortable when sleeping. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of how to obtain a seamless (sewn) quilt with lace trim that provides a comfortable feel to the body parts that come into contact with the edge of the quilt during sleep.

[0004] To address the aforementioned problems, the present invention provides a seamless quilt with no visible lace, 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 edge of the seamless quilt is formed by bonding and closing the edges of the upper and lower layers, and the edge is provided with lace formed by the edges of the upper and lower layers on the edge.

[0005] Preferably, the seamless side of the user's head is formed by bonding the edges of the upper and lower layers of the side together, and the side is provided with a lace formed by the edges of the upper and lower layers of the side.

[0006] Preferably, the edge of the seamless quilt is formed by bonding the edges of the upper layer and the lower layer together, and the edge of the seamless quilt is provided with a lace formed by the edges of the upper layer and the lower layer.

[0007] Preferably, the shape of the lace includes wavy, serrated, irregular arc, or intermittent hollow shape.

[0008] Preferably, the lace is formed by cutting, punching, or laser cutting.

[0009] Preferably, a predetermined area of ​​the upper layer and / or the lower layer is provided with an adhesive, and the upper layer and the lower layer are glued and fixed through the core material in the predetermined area; the shape of the predetermined area includes circular, annular, dotted, strip-shaped, or petal-shaped.

[0010] 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.

[0011] Preferably, the core material is a prefabricated integral core material.

[0012] Preferably, the integral core material is configured as a composite structure, and the composite structure includes multiple composite layers.

[0013] Preferably, the multi-layered composite layers are configured as layers with different elasticity, different breathability, different heat retention capacity, or different loft; the integral core material is configured as 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 using an adhesive bonding process, and overcomes the shortcomings of existing seamless quilts where the straight edges of the upper and lower quilt surfaces are bonded together, resulting in a hard feel and discomfort when the neck or other parts of the body come into contact with the hard edges. By changing the straight edges of the glued seamless quilt to a wavy or other lace structure, the area in contact with the skin is reduced, and the weight of the edges is lightened, thereby reducing the pressure on the neck and other parts of the body. This provides a seamless quilt product with a softer and more comfortable user experience. Attached Figure Description

Detailed Implementation

[0023] To make this application more apparent and understandable, various exemplary embodiments will be described below. These examples are non-limiting and should be understood as illustrating aspects of the broader application of the apparatus, system, and method. These embodiments can be varied and substituted with equivalents without departing from the spirit and scope of this application.

All such variations will be within the protection scope of this application.

[0024] Any materials, dimensions, or quantities described in the overview or detailed description are merely examples and are not intended to limit the subject matter of this application. 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.

[0025] In the description of this application, it should be noted that the terms "inner", "outer", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] 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.

[0027] See Figures 1-6 This application provides a seamless quilt with wavy edges, comprising an upper layer 100, a lower layer 200, and a core material 300 wrapped between the upper layer 100 and the lower layer 200; a plurality of predetermined areas 400 coated with adhesive are provided on the upper layer 100 and the lower layer 200, and the upper layer 100 and the lower layer 200 are bonded together through the core material 300 in these predetermined areas 400 to form a three-layer seamless quilt; the edges of the upper layer 100 and the lower layer 200 are wavy.

[0028] The core material 300 has 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.

[0029] like Figure 3 As 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 predetermined area 400 at the edge of the lower layer 200 is set as a second adhesive application area 220; the upper layer 100 passes through a pre-set 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 around their perimeters; the upper layer 100 and the lower layer 200 are bonded together through the pre-set through-hole on the core material 300, thereby restricting the movement of the core material 300; the seamless is closed off around its perimeter, enclosing the entire core material 300. Subsequently, a wavy lace is formed by cutting the second adhesive application area 220 around the seamless perimeter; since the adhesive edge is wavy, it reduces the weight of the user contacting the harder adhesive edge, making the feel relatively soft.

[0030] In one embodiment, the seamless, glued edge corresponding to the user's head is cut into a wavy shape; during use, the user's head and neck come into contact with the soft, seamless lace edge, providing a more comfortable contact experience.

[0031] In another embodiment, the seamless edges glued on all sides are cut into a wavy shape; as shown... Figure 1 As shown, when in use, the user's body comes into contact with the soft, seamless lace edge, providing a relatively comfortable contact experience.

[0032] 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 layer 100 and the lower layer 200 should be continuously and fixedly connected to enclose the core material; while for integral core materials, the edges of the upper layer 100 and the lower layer 200 can also be intermittently and fixedly connected, which can also serve to enclose the core material.

[0033] 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.

[0034] 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 and a second adhesive application area 220 are provided on the inner side of the lower layer 200 facing the upper layer 100 in the predetermined area 400; 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 and the second adhesive application area 220, thereby limiting the position of the core material.

[0035] The specific production steps of a seamless quilt with wavy lace trim:

[0036] Step 1: Prepare a rectangular top layer 100 and a bottom layer 200, and set a predetermined area 400 on the top layer 100 and the bottom layer 200;

[0037] Step 2: Set up a first adhesive application area 210 and a second adhesive application area 220 inside the predetermined area 400. Apply adhesive to the first adhesive application area 210 and the second adhesive application area 220 using a dispensing machine or adhesive film. Then, cover the core material 300 on the lower layer 200, avoiding the adhesive application area, and then cover the upper layer 100.

[0038] Step 3: Hot-press the overlapping upper layer 100 and lower layer 200 to glue and fix them at the first adhesive application area 210 and the second adhesive application area 220 of the corresponding predetermined areas to form the connecting part 500.

[0039] Step 4: Maintain pressure until the upper layer 100 and the lower layer 200 are bonded together, resulting in a seamless sheet with straight edges;

[0040] Step 5: Laser cut the edges of the seamless blanket with straight edges to obtain a seamless blanket with wavy edges.

[0041] When using a dispensing machine, the adhesive used can be a moisture-curing adhesive or a hot melt adhesive. When using a moisture-curing adhesive, after dispensing the lower layer 200, the core material 300 and the upper layer 100 should be laid on the lower layer 200 as soon as possible, ensuring continuous contact between the upper layer 100 and 200 until the moisture-curing adhesive hardens. When using a hot melt adhesive, after dispensing the lower layer 200 and laying the core material 300 and upper layer 100 on it, in addition to applying pressure to the upper layer 100 and lower layer 200, the adhesive needs to be heated to melt the dots and bond the upper layer 100 and lower layer 200 together.

[0042] When using an adhesive film for dispensing, the adhesive used is a hot melt adhesive. During application, first peel off the first release film to expose the adhesive, then confirm that the adhesive is in contact with the lower layer. Next, peel off the second release film to fully expose the adhesive. Then, place the core material 300 in a location avoiding the predetermined area, and cover it with the upper layer 100, ensuring that the upper layer 100 and the lower layer 200 are bonded and fixed together.

[0043] 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, and the edges of the upper layer 100 and the lower layer 200 are glued and fixed in the second adhesive application area 220.

[0044] In a further implementation, see Figure 4 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.

[0045] 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.

[0046] 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.

[0047] 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.
