Description

Technical Field

[0001] The utility model belongs to the field of ball processing and production, and specifically relates to a laminated ball. Background Art

[0002] At present, some leather-covered balls on the market, such as leather-covered basketballs, have skin materials other than rubber materials, and the skin materials of leather-covered basketballs also include materials such as PVC, PU, ​​superfiber and cowhide. The price of cowhide basketballs is too high to satisfy mass consumers, so synthetic leather basketballs occupy the main market. However, synthetic leather will produce a large amount of waste gas and waste liquid during the production process, causing serious environmental pollution and not being environmentally friendly enough. In addition, basketballs made of synthetic leather cannot be made with too many patterns, and the products are too single, making it impossible to produce more aesthetically pleasing and personalized basketballs, and the feel of the leather-covered balls of these skin materials is relatively hard, and the plastic feel is stronger. However, EVA foam material is soft in material and is an environmentally friendly material. At present, there is no leather-covered ball with EVA foam material as the skin in this field. Summary of the invention

[0003] The utility model aims to provide a leather-covered ball which is soft in texture, environmentally friendly and simple in structure.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A laminated ball comprises a ball-in-ball and a ball skin attached to the surface of the ball-in-ball. The ball skin comprises an EVA foam layer attached to the surface of the ball-in-ball and a film layer attached to the surface of the EVA foam layer. The EVA foam layer and the film layer are bonded by glue.

[0006] The EVA foaming layer is bonded to the tire in the ball by glue.

[0007] The material of the film layer is a transparent material.

[0008] The material of the film layer is one of TPU, EVA, silicone and EPDM.

[0009] The ball skin also includes a trademark layer A, which is arranged on a partial area of ​​the surface of the EVA foam layer. The trademark layer A is bonded to the surface of the EVA foam layer by glue. The trademark layer A is located on the inner side of the film layer and the surface of the trademark layer A is bonded to the film layer by glue.

[0010] The material of the film layer is a non-transparent material.

[0011] The ball skin also includes a trademark layer B, which is arranged on a partial area of ​​the surface of the film layer.

[0012] The material of the EVA foam layer is EVA foam material.

[0013] The thickness of the EVA foam layer is 0.8-2 mm, and the thickness of the film layer is 0.1-0.2 mm.

[0014] The tire in ball comprises a ball bladder, a yarn wrapping layer arranged on the periphery of the ball bladder, and a middle tire skin layer arranged on the periphery of the yarn wrapping layer.

[0015] The surface of the film layer is provided with a texture that increases friction.

[0016] Compared with the prior art, the utility model has the advantages that the laminated ball of the utility model has the advantages of soft touch, wear resistance, low cost and environmental protection. Taking the laminated basketball as an example, the provision of the EVA foam layer makes the entire basketball feel soft, improving the plastic feel of the traditional laminated basketball. When the film layer is a transparent material, it can make the surface of the basketball show the pattern of the trademark and the color of the EVA foam layer, while protecting the EVA foam layer and increasing the wear resistance of the entire basketball. Combined with the EVA foam layer, it can make the basketball have a soft texture and wear resistance. The thickness of the EVA foam layer is 0.8-2mm, and the thickness of the film layer is 0.1-0.2mm, which can ensure that the ball has a suitable bounce degree and make the ball have wear resistance and soft texture.

[0020] Explanation of reference numerals: 1 ball middle tire, 11 ball inner liner, 12 yarn winding layer, 13 middle tire skin layer, 131 ribs, 2 ball skin, 21 EVA foaming layer, 22 film layer, 23 trademark layer A, 24 trademark layer B. DETAILED DESCRIPTION

[0021] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0022] like Figure 1 , Figure 2 Shown is a schematic diagram of an embodiment of a leather-covered ball provided by the utility model.

[0023] The laminated ball is a laminated basketball, which includes a ball-in-ball tire 1 and a ball skin 2 attached to the surface of the ball-in-ball tire 1. The ball skin 2 includes an EVA foam layer 21 attached to the surface of the ball-in-ball tire 1 and a film layer 22 provided on the surface of the EVA foam layer 21. The EVA foam layer 21 and the film layer 22 are bonded by glue.

[0024] The film layer 22 can protect the EVA foam layer 21 and increase the wear resistance of the ball.

[0025] Since the laminated ball is a laminated basketball, the ball-in-tire 1 is a basketball-in-tire, and the surface of the basketball-in-tire is provided with ribs 131 (also called stems or grooves), and the EVA foam layer 21 is attached to the area between the ribs 131 on the surface of the basketball-in-tire. For some basketball-in-tire without ribs (after the ball-in-tire without ribs is attached to the entire ball surface, grooves for accommodating the ribs are pressed out on the ball surface by heat pressing or other operations, and then the ribs are glued or heat-sealed in the grooves through subsequent processing, or the rib lines are drawn on the basketball surface, etc.), the EVA foam layer 21 can be glued to the surface of the entire ball-in-tire 1, and the corresponding film layer 22 also covers the entire ball surface area.

[0026] The EVA foam layer 21 is bonded to the surface of the tire-in-ball 1 by glue.

[0027] The film layer 22 is made of transparent material.

[0028] The material of the film layer 22 is one of TPU, EVA, silicone and EPDM.

[0029] The transparent film layer 22 can make the surface of the ball show the pattern of the trademark and the color of the EVA foam layer 21, and at the same time can protect the EVA foam layer 21 and increase the wear resistance of the entire basketball. Combined with the EVA foam layer 21, it can make the basketball soft and wear-resistant.

[0030] The ball skin 2 also includes a trademark layer A23, which is arranged on a partial surface area of ​​the EVA foam layer 21. The trademark layer A23 is bonded to the surface of the EVA foam layer 21 by glue. The trademark layer A23 is located on the inner side of the film layer 22, and the surface of the trademark layer A23 is bonded to the film layer 22 by glue.

[0031] The designed transfer trademark is pasted on the surface of the EVA foam layer 21 to form a trademark layer A25.

[0032] The thickness of each glue and the trademark layer A are extremely thin compared to the EVA foam layer 21, the film layer 22 and other layers. Therefore, in the drawings of the present utility model, the thickness of the glue and the trademark layer A is not specifically reflected. Only because the trademark layer A21 is located on the inner side of the film layer 22, that is, between the EVA foam layer 21 and the film layer 22, the area where part of the trademark layer A21 is located is represented by a dotted frame, as shown in FIG. Figure 1 shown.

[0033] The material of the EVA foam layer 21 is EVA foam material, such as some existing bio-based and degradable environmentally friendly EVA foam materials on the market.

[0034] Here, the EVA material of the film layer 22 and the EVA foam material of the EVA foam layer need to be explained. The EVA material of the film layer 22 and the EVA foam material of the EVA foam layer are not the same material. The EVA foam material is a material made by high-temperature foaming with EVA (ethylene-vinyl acetate copolymer) as the main raw material and auxiliary materials such as foaming agent and filler. The EVA material is ethylene-vinyl acetate copolymer.

[0035] The thickness of the EVA foam layer 21 is 2 mm, and the thickness of the film layer 22 is 0.1 mm.

[0036] For a laminated basketball, when the thickness of the EVA foam layer 21 is 2 mm and the thickness of the film layer 22 is 0.1 mm, the ball can have the proper bounce and can also be wear-resistant and soft. Of course, the thickness of the EVA foam layer 21 and the film layer 22 can be adjusted according to actual needs, but the overall thickness range is 0.8-2 mm for the EVA foam layer 21 and 0.1-0.2 mm for the film layer 22.

[0037] The tire-in-ball 1 comprises a ball bladder 11 , a yarn wrapping layer 12 arranged on the periphery of the ball bladder 11 , and a middle tire skin layer 13 arranged on the periphery of the yarn wrapping layer 12 .

[0038] like Figure 1 , 2 As shown, the ribs 131 are integrally formed with the middle tire skin layer 13 .

[0039] The surface of the film layer 22 is provided with a texture for increasing friction.

[0040] The texture setting can facilitate users to grasp the basketball and improve the grip and friction of the basketball.

[0041] Of course, the laminated ball can also be a laminated volleyball. For example, the thickness of the EVA foam layer 21 can be set to 0.8 mm, and the thickness of the film layer 22 can be set to 0.2 mm. The laminated ball can also be a laminated rugby or other sports ball. They are not listed here one by one.

[0042] Another implementation example is Figure 3 As shown, the structure of this embodiment is similar to the structure of the laminated basketball described in the above embodiment, but there are the following differences:

[0043] The material of the film layer 22 is a non-transparent material, such as some TPU, EVA, silica gel, EPDM materials with colorants, etc.

[0044] The ball skin 2 also includes a trademark layer B24, which is disposed on a partial area of ​​the surface of the film layer 22. The trademark layer B24 can be bonded to the surface of the film layer 22 by glue, or the trademark layer B24 can be printed on the surface of the film layer 22 by other means. Similarly, since the thickness of the trademark layer B24 is extremely thin compared to the thickness of other layers, the drawings of the utility model do not reflect the thickness of the trademark layer B24, and only show the trademark layer B24 in a partial area on the film layer 22.

[0045] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
