Description

Technical Field

[0001] This utility model relates to a shoe upper, specifically a one-piece fused and filled down shoe upper. Background Technology

[0002] In footwear products, especially winter warm shoes, the warmth of the upper is crucial. Traditional warm shoe uppers suffer from the following problems to varying degrees during manufacturing: 1. Uneven down filling: The manufacturing process involves quilting first and then filling, which prevents the down material from being evenly distributed into the insulation. For example, in the production of indoor warm slippers, the upper layer is fluffy and three-dimensional after filling, and after being sewn to the lining, the thickness of the entire upper layer is uneven, resulting in differences in warmth performance; 2. Low production efficiency: Traditional warm shoe uppers require multiple operations and are cumbersome. For example, current down-filled indoor slippers are limited by quilting, making it extremely difficult to sew the pattern in the middle of the upper layer after filling, and requiring processing each area individually, which is not only labor-intensive but also inefficient; 3. Limited down filler loft: Currently, there is no specialized down filling and quilting equipment for footwear, which greatly limits the loft of the filling and other insulating materials, indirectly leading to poor warmth retention. To address this, the inventor designed a one-piece fused and plush-filled shoe upper. Utility Model Content

[0003] The purpose of this invention is to provide an integrated fused and filled down upper, which has the advantages of simple structure, reasonable design, good down filling uniformity, high production efficiency, and good down filling loft, thus solving the problems mentioned in the above technical background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated melt-fitted and filled down upper, the upper comprising an inner lining and a thermal bladder, the thermal bladder being formed on the inner lining using a seamless hot-melt process, and the thermal bladder comprising a bladder body, the bladder body being a hollow cavity structure with an opening at the lower end, the cavity being filled with thermal down, the inner lining being located at the lower end of the thermal bladder and encapsulating the thermal down within the bladder body, the bladder body comprising an outer sheath layer and an inner sheath layer, an adhesive layer being provided between the outer sheath layer and the inner sheath layer, and the outer sheath layer and the inner sheath layer being formed together by a composite process.

[0005] Preferably, a hot melt adhesive film is provided at the connection between the inner lining and the warming pouch.

[0006] Preferably, there are multiple warming pouches, which are evenly distributed on the inner surface. The width of each warming pouch is between 1.5cm and 2cm, and the height is between 1cm and 1.5cm.

[0007] Preferably, the outer lining layer is a woven fabric with a thickness between 0.5 mm and 1 mm.

[0008] Preferably, the inner lining layer is a single-layer mesh fabric, and the inner lining layer is provided with a plurality of triangular mesh holes.

[0009] Preferably, the adhesive layer is a high-temperature film with a thickness between 0.01 mm and 0.05 mm.

[0010] Preferably, the insulating fleece is wool.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an integrated fused and filled down-filled shoe upper, which includes an inner lining and a thermal bladder. The overall structure is simple and reasonably designed. The thermal bladder is formed on the inner lining using a seamless hot-melt process, which is more efficient than quilting. The bladder body includes an outer layer and an inner layer, with an adhesive layer between them. The outer and inner layers are formed together by a composite process. The inner layer is a single-layer mesh fabric with several triangular mesh holes. When the down-filling is filled into the thermal bladder, it can be fixed through the triangular mesh holes, making the down-filling more uniform and preventing it from shifting. At the same time, the down-filling is made of wool, which can effectively ensure its fluffiness and achieve good warmth retention. Attached Figure Description

[0017] Please see Figure 1 and Figure 2 This utility model provides an embodiment of an integrated, melt-fitted, plus-filled shoe upper. The upper includes an inner lining 1 and a thermal insulation bladder 2. The overall structure is simple. The thermal insulation bladder 2 is seamlessly hot-melt molded onto the inner lining 1, which is more efficient than traditional quilting. The thermal insulation bladder 2 includes a bladder body 21, which is a hollow cavity structure with an opening at the lower end. Thermal insulation fleece 22 is filled inside this cavity. The inner lining 1 is located at the lower end of the thermal insulation bladder 2 and encapsulates the thermal insulation fleece 22 within the bladder body 21. A hot-melt adhesive film 3 is provided at the connection between the inner lining 1 and the thermal insulation bladder 2. The thickness of the hot melt adhesive film 3 is 0.3 mm. The hot melt adhesive film 3 is melted by a high-frequency hot melt process and then the heat insulation pouch 2 is fused to the inner lining 1. Before fusion, the heat insulation fleece 22 needs to be filled into the pouch body 21. This can solve the problem of uneven fleece filling later. The pouch body 21 includes an outer lining layer 211 and an inner lining layer 212. An adhesive layer 213 is provided between the outer lining layer 211 and the inner lining layer 212. The outer lining layer 211 and the inner lining layer 212 are formed together by a composite process. The adhesive layer 213 is a high-temperature film with a thickness between 0.01 mm and 0.05 mm.

[0018] Specifically, multiple warming pouches 2 are provided, and the multiple warming pouches 2 are evenly distributed on the inner lining 1. The width of each warming pouch 2 is between 1.5cm and 2cm, and the height is between 1cm and 1.5cm.

[0019] Specifically, in this embodiment, the outer lining layer 211 is a woven fabric with a thickness between 0.5mm and 1mm. The inner lining layer 212 is a single-layer mesh fabric with several triangular mesh holes 214. The mesh holes 214 can effectively fix the thermal fleece 22, prevent it from moving, and ensure the uniformity of the thermal fleece 22. The thermal fleece 22 is wool with good loft.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
