[0001] The present invention relates to the technical field of toy manufacturing, and more particularly to a fur-implanted reinforcement structure for a stuffed toy and a stuffed toy equipped with the same. [Background technology]

[0002] The current technical limitations in fastening toy doll wigs are as follows:

[0003] 1. Hair implantation process for vinyl dolls: Using a hair implantation machine, the mechanical binding force of the vinyl is used to hook the bobbin thread and implant hair into the vinyl material (e.g., Barbie doll).

[0004] 2. Wig pasting process: Glue the entire wig onto the surface of the doll's head.

[0005] However, the above process cannot be applied to stuffed toys, mainly for the following reasons:

[0006] 1. The body of the plush toy is made of woven fabric sewn together and stuffed with cotton, and the fabric is not very resistant to deformation.

[0007] 2. The hook of the flocking machine cannot effectively catch the bobbin thread on thin fabric layers (actual measurements show that the rate of bobbin thread slippage is over 90%).

[0008] 3. The wig's pulling force is less than 5N, which is far below the toy safety standard (ASTM F963 requires a force of 15N or more).

[0009] 4. It is impossible to achieve sophisticated designs such as high density hair flocking on curved surfaces, which places significant limitations on product development.

[0010] Therefore, in order to solve the above problems, a fur-implanted reinforcement structure for a stuffed animal and a stuffed animal equipped with the same have been developed. Summary of the Invention [Problem to be solved by the invention]

The terms used in the description of the invention herein are for the purpose of describing particular embodiments only and are not intended to be limiting of the invention. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] The present invention will be further described below with reference to the drawings and specific embodiments.

[0026] As shown in Figures 1 to 7, the flocked reinforcement structure of the plush toy includes a physical reinforcement body 10 molded from a soft material by a vinyl casting, injection molding, or press molding process; The reinforcement 10 has a contact surface that conforms to the contour of the inner wall of the flocked area 201 in which it is located; The spatial form of the reinforcing body 10 is a two-dimensional continuous sheet or a three-dimensional space liner, The two-dimensional continuous sheet has a thickness uniformity deviation of ±10% or less, a thickness range of 0.5 mm to 6 mm, and a surface roughness Ra of 12.5 μm or less, and the edge of the two-dimensional continuous sheet extends outside the boundary of the flocked region 201, The three-dimensional space liner includes a curved topological structure, covers 50% or more of the inner surface of the flocked region 201, has a thickness ranging from 0.5 to 6 mm, and has a thickness variation rate of 30% or less.

[0027] In this embodiment, the thickness of the reinforcement 10 is set according to the requirements of the application site, bonding method, and molding process, and the thickness of the reinforcement 10 is 0.5 mm to 6 mm. In actual production, the higher the tensile strength requirement of the reinforcement 10, the larger the thickness.

[0028] In this embodiment, the topology structure of the three-dimensional space liner is designed to support deep implantation of long needles with a maximum thickness of 6 mm, preventing local collapse, and the minimum coverage rate is 50%, effectively reducing material costs.

[0029] In this example, the surface roughness Ra of the two-dimensional continuous sheet is 12.5 μm or less, so that the adhesive peel strength reaches 18 N / cm, and the thickness uniformity deviation is ±10% or less, so that the stability of the flock density can be improved.

[0030] Furthermore, the three-dimensional space liner includes a reinforcing rib grid and / or a micropit array, and the rib height of the reinforcing rib grid is 0.3 to 1 mm; The pit depth of the micropit array is 0.1 to 0.5 mm.

[0031] In this example, the rib height of the reinforcing rib grid can prevent the fabric from tearing too far, increasing puncture resistance, and the pit depth of the micropit array increases adhesive contact area by 150%, improving interfacial strength.

[0032] Furthermore, as shown in Figures 1 to 7, the material of the reinforcing body 10 is set according to the requirements of the application site, bonding method, and molding process, and the material of the reinforcing body 10 is at least one of PVC, TPU, TPE, rubber, silicone rubber, and composite materials thereof.

[0033] Furthermore, as shown in FIGS. 1 to 7, the Shore hardness of the reinforcing body 10 is set according to the requirements of the application site, the bonding method, and the molding process, and the Shore hardness of the reinforcing body 10 is 15A to 70A.

[0034] In this embodiment, the processed reinforcing member 10 is placed on the fabric inside the hair-implanting area 201 of the stuffed toy body 20, and then the reinforcing member 10 is fixed with hot melt adhesive or sewing thread, after which the wig implantation operation is performed using an automatic hair implantation machine. As a result, the hair implantation thread penetrates the fabric of the stuffed toy and is hooked onto the reinforcing member 10 or is firmly supported by the reinforcing member 10. Compared to the conventional direct hair implantation method, the hair implantation thread is firmly hooked onto the reinforcing member 10, which solves the problem that the implanted wig is easily pulled out due to the thin fabric of the stuffed toy body 20.

[0035] In this embodiment, the reinforcement 10 is fixed by gluing or sewing in perfect contact with the inner wall of the toy.

[0036] The method for manufacturing the fur-implanted reinforcement structure for the stuffed toy is as follows.

[0038] 3D Space Liner: S1. A mold is designed based on three-dimensional data of the inner wall of the hair implantation area 201. S2.Mold it into one piece by injection molding / press molding / vinyl casting / drop molding in the mold.

[0039] Common step: The molding is fixed to the inner wall of the stuffed toy via an adhesive layer or sewing thread 401.

[0040] Furthermore, the cutting step employs laser cutting or water jet cutting, and the cutting accuracy error is 0.2 mm or less.

[0041] A stuffed toy including a stuffed toy body 20 sewn from woven fabric and stuffing 30, The fur-implanted reinforcement structure of the stuffed toy according to any one of the above items is fixed to the inside of the fur-implanted area 201 of the stuffed toy body 20, A continuous interface layer 40 is formed between the contact surface of the fur-implanted reinforcement structure of the stuffed toy and the inner wall of the toy, The coverage of the continuous interface layer 40 is 90% or more.

[0042] Furthermore, the continuous interface layer 40 is a hot melt adhesive layer, a silicone rubber layer, a polyurethane adhesive layer, or a seam 401 .

[0043] Furthermore, when the fur-implanted reinforcement structure of the stuffed toy is a three-dimensional space liner, a buffer air gap layer (not shown) is provided between the inner surface and the stuffing 30, The buffer air gap layer has an air gap thickness of 0.2 to 1 mm and an air gap interconnection rate of 60% or more.

[0044] In this embodiment, the provision of a buffer air gap layer can absorb the tensile energy of the flock, reduce the peak stress by 30%, and prevent the padding 70 from directly compressing the three-dimensional space liner and causing deformation.

[0045] In this embodiment, the coverage rate of the continuous interface layer 40 is 90% or more, which upgrades the reinforcement from a "local reinforcement member" to a "full load structure" and solves the problem of being unable to implant industrial-grade fur in stuffed toys.
