[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0021] Reference Figure 1 and Figure 2 A multifunctional, customizable duvet insert includes a duvet cover, which comprises a face fabric 1, a back fabric 6, and wadding filling. The wadding is quilted and connected to the back fabric 6 as a single unit, but not connected to the face fabric 1, thus creating a cavity between them. The face fabric 1 has openings that allow this cavity to be accessed. The duvet cover and wadding form the main duvet insert. The wadding can be any combination of fibers with different functions, including but not limited to antibacterial fibers, anti-mite fibers, far-infrared fibers, protein fibers, porous fibers, moisture-wicking fibers, and natural fibers.
[0022] A multifunctional, customizable comforter core also includes a sub-comfort core, which can have the same structure as the main comforter core or a conventional structure. The filling of the sub-comfort core can be any combination and combed of fibers with different functions, including but not limited to antibacterial fibers, anti-mite fibers, far-infrared fibers, protein fibers, porous fibers, moisture-wicking fibers, etc., or it can be a natural fiber comforter core such as silk, wool, down, or cotton.
[0023] When the weather is hot, the main comforter can be used alone, and when the weather is cold, the secondary comforter can be inserted into the receiving cavity.
[0024] Specific embodiment 1, such as Figure 1 As shown
[0025] The opening is U-shaped, with a distance between each side of the opening and the sides of the outer fabric 1. The bottom edge of the opening extends to the bottom connection edge of the outer fabric 1 and the bottom fabric 6, and the top edge of the opening extends to the top connection edge of the outer fabric 1 and the bottom fabric 6. Both sides of the opening can be opened, and one of the top or bottom edges of the opening can be opened while the other cannot. Figure 1 5 in the figure is the connecting edge of the front fabric 1 and the back fabric 6 on the left side.
[0026] The main comforter filling is a blended quilt, made from 30% moisture-wicking fibers, 20% soybean protein fibers, 40% antibacterial and anti-mite fibers, and 10% low-melting-point fibers. This blended quilt is existing technology and can be purchased directly; product model number SX719346. The second comforter filling has a weight of 280g / m². 2 This is a pure down comforter. The comforter core is filled within the cavity. This versatile, customizable comforter core offers excellent antibacterial and anti-mite properties, as well as skin-friendly comfort, while also providing the superior warmth of a down comforter.
[0027] Specific embodiment 2, such as Figure 2 As shown
[0028] The opening is U-shaped, with its two sides coinciding with the junctions of the front fabric 1 and the back fabric 6 on both sides. The bottom edge of the opening extends to the junction of the front fabric 1 and the back fabric 6 at the bottom, and the top edge extends to the junction of the front fabric 1 and the back fabric 6 at the top. Both sides of the opening can be opened, and one of the top or bottom edges of the opening can be opened while the other cannot. Figure 2 5 in the figure is the connecting edge of the front fabric 1 and the back fabric 6 on the left side.
[0029] The main quilt filling is a blended quilt, made from 30% intelligent temperature-regulating fibers, 20% milk protein fibers, 40% negative ion fibers, and 10% low-melting-point fibers. This blended quilt is existing technology and can be purchased directly; product model number SX719476. The quilt itself weighs 280g / m². 2 This is a pure silk quilt. It boasts excellent temperature control, is skin-friendly and comfortable, rich in amino acids, and releases negative ions for a refreshing sleep environment.
[0030] In both embodiments described above, preferably, the top of the opening cannot be opened, but the bottom of the opening can be opened. The face fabric 1 and the back fabric 6 can be formed by folding a single piece of fabric in half, with the fold located at the top. This reduces quilting.
[0031] In the two embodiments described above, the shape of the opening has been optimized to maximize the opening angle to 270 degrees, thereby facilitating the insertion of the quilt insert.
[0032] In both of the above embodiments, when inserting the quilt insert, the main quilt insert is first laid on the bed, the opening is opened, and then the quilt insert is laid on top, and the opening is closed, which is very convenient. Specific Implementation Example 3
[0034] The opening is located on one or more connecting edges of the face fabric 1 and the bottom. For example, the opening is "L"-shaped. The wadding of the main comforter can be polyester fiber wadding, cotton wadding, wool wadding, or silk wadding. The main comforter can be used alone without a secondary comforter inside the receiving cavity.
[0035] In the above embodiments, a zipper 2 is provided at the opening, allowing a single zipper to pass through all sides of the opening, thereby reducing the number of zipper ends. In this case, the zipper is preferably arc-shaped at the bends, making the zipper pull smoother.
[0036] In the above embodiments, it is preferable that the corners and / or edges of the duvet cover are provided with connectors 4. Connectors 4 include an outer connector located on the outside of the duvet cover for connecting to the duvet cover, and may also include an inner connector located on the inside of the duvet cover for connecting to the duvet insert. The inner and outer connectors can be connected together in a one-to-one correspondence. Particularly preferably, an opening is provided at the connector, and the connector is a rope-like webbing that passes through the opening and can slide within it, thereby adjusting the size of the connector by sliding the webbing. More importantly, the webbing can be passed through the opening, inserted into the duvet cover, then through the connector on the duvet insert to position the duvet insert, then through the opening again to extend out of the duvet cover, and finally connected to the duvet cover by a knot to secure it. Thus, the duvet cover, main duvet insert, and duvet insert are connected with a single knot, which is convenient and reduces discomfort.
[0037] In the above embodiments, the outer perimeter of the duvet cover may be provided with a quilt edge. The quilt edge can have various styles.
[0038] In the above embodiments, a cover fabric is also provided at the opening to conceal the zipper, thereby preventing the zipper from being exposed and scratching the user or snagging other objects. Alternatively, a wide edging can be provided at the opening, located on the outside of the zipper. This wide edging effectively conceals the zipper, preventing it from being exposed and avoiding any discomfort to the human body from contacting it.
[0039] In the above embodiments, the zipper is preferably an invisible zipper. Compared with the button connection method, the zipper connection method can effectively solve the following technical problems of the button connection method: 1. There is a gap between the two buttons, which makes the duvet insert easily exposed from the position between the two buttons; 2. The buttons are exposed outside the duvet cover body, which affects the appearance and is easy to snag on other objects.
[0040] In the above embodiments, the face fabric 1 and the back fabric 6 can be made into different connection styles, but preferably, the quilted connection shown in the figure is preferred.
[0041] In the above embodiments, the sub-quilt cores can be independent quilt cores with different weights, functions, and materials.
[0042] In the above embodiments, the upper layer fabric 1 and the lower layer fabric 6 of the duvet cover can be made of different materials to achieve a double-sided, dual-feel design, thus enabling the duvet cover to be used on both sides. For example, one side can be made of a cooling fabric, and the other side can be made of a brushed fabric.
[0043] In each of the above embodiments, a limiting structure is provided at each corner of the duvet cover. The limiting structure is a hook and loop fastener, which works in conjunction with the webbing of the duvet insert. The hook and loop fastener are opened, pass through the webbing, and then closed, thereby limiting the movement of the duvet insert. A limiting structure is provided at the middle position of the foot edge of the duvet cover, and a limiting structure is provided at the middle position of the head edge of the duvet cover. At least three limiting structures are provided on the sides to effectively prevent the duvet insert from shifting.
[0044] Note that in this invention, the inner side of the opening is used as the opening fabric 3. In specific embodiment 1, the area of the opening fabric 3 is smaller than the overall area of the fabric. In specific embodiment 2, the entire fabric is used as the opening fabric.
[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
