Colorful patterned toy balls

Abstract

A colorful patterned toy ball includes a plastic sphere and at least one adhesive layer. The plastic sphere comprises a pair of hemispheres, each hemisphere having an inner surface and an outer surface. Corresponding joints are provided at the openings of the two hemispheres, allowing them to be combined into one unit. The adhesive layer comprises a circular central portion and a plurality of fan-shaped portions extending outwards from the circumference of the central portion, forming a soft plastic sheet structure. A pattern layer is offset-printed on the exterior of the adhesive layer, and an adhesive layer is provided corresponding to the material of the hemisphere. The inner and / or outer surfaces of the hemisphere are fixed by in-mold bonding, enabling the appearance to exhibit multi-block, multi-angle, and multi-color pattern printing effects, effectively reducing manufacturing costs and time.

Claims

1. A colorful patterned toy ball, the appearance of which can display decorative effects of multiple blocks, multiple angles, and multiple colors, comprising: A plastic sphere, having a fixed shape and not inflatable, comprises a pair of hemispheres, each hemisphere having an inner surface and an outer surface, and a corresponding joint at the opening of each hemisphere to combine the two into one; and at least one adhesive layer, the adhesive layer comprising a circular central portion and a plurality of fan-shaped portions extending outwardly along the circumference of the central portion as a soft plastic sheet structure, fixed to the inner surface and / or the outer surface of the hemisphere by in-mold bonding, so that the adhesive layer fully adheres to the inner surface and / or the outer surface, and a pattern layer is provided on the outside of the adhesive layer by offset printing.

2. The colored patterned toy ball as described in claim 1, wherein, Each blade is trapezoidal in shape, with a narrow inner arc and a wide outer arc, and the length of each blade is no greater than the diameter of the central part.

3. The colored patterned toy ball as described in claim 1, wherein, The diameter of the central part is no greater than the radius of the hemisphere.

4. The colored patterned toy ball as described in claim 1, wherein, Each blade is set at equal intervals.

5. A colored patterned toy ball as described in any one of claims 1 to 4, wherein, The ratio of the outer arc length to the inner arc length of each blade is approximately 3:

1.

6. A colored patterned toy ball as described in any one of claims 1 to 4, wherein, The inner arc length of each blade is within one-third ± 5% of the diameter of the central part, and the distance between two adjacent blades is within the radius of the central part ± 5%.

7. The colored patterned toy ball as described in claim 1, wherein, Depending on the material of the plastic sphere, the adhesive layer must have an adhesive layer to increase the fit and stability of the adhesive layer on the surface of the hemisphere.

8. A colored patterned toy ball as described in claim 1 or 7, wherein, When used in the blow molding process to produce the hemisphere, the adhesive layer is attached to the outer surface, the pattern layer is printed in color on the outside of the adhesive layer, and the bonding layer is located inside the adhesive layer, preferably the bonding layer is transparent.

9. A colored patterned toy ball as described in claim 1 or 7, wherein, When used in the injection-molded hemisphere, the adhesive layer is attached to the inner surface, and the hemisphere is transparent. The bonding layer and the pattern layer are stacked on the outside of the adhesive layer, and the bonding layer is preferably transparent.
