New description: [New technical field]: Innovative: It is used in a cover for earmuffs, especially for earmuffs that reduce the external noise. A /, [Prior Art] Generally used to block the high-decibel external noise in the workplace for the user to cross the tone, $ 氐椹 "" 耳 用 earmuff headphones, the basic knot witches The two ends of the wood are fixedly covered by the user's ear 1\. The cover body has a plurality of structures, as shown in Fig. 1, which is a sound-insulating mat 1 formed of - material. The outer surface is covered with a soft surface layer 11 made of a polymer material, so that the soft enamel sheet < ln 4 text take-up layer 11 firmly covers the sound-insulating mat ' 乃 猎 猎 黏 12 (or high-frequency bonding) In combination with the two, Xiang:)::: The soundproofing pad 10 having the soft surface layer 11 is formed by the double-sided tape 13 (or adhered to the clamshell 14 to form the cover i shown in FIG. "As mentioned above, the cover body is basically composed of the sound insulation pad 1Q and the difficult surface layer n 2 and 14". However, the components of the three components must be separately formed, so that the soft shell surface layer 11 must first be glued or high. A conventional bonding medium or method such as a Zhou-Bo bond is adhered to the sound-insulating mat 10 to be coated. Then, the sound-insulating mat 1 covered with the soft surface layer 11 is adhered to the conventional plum mass such as double-sided tape or adhesive. On the plastic shell 14. This kind of process requires two bonding procedures, which is not only time-consuming, but also the adhesive double-sided adhesive or the adhesive of the circumference is caused by the increase of production cost, and it is difficult to meet the requirement of reducing the production cost. 5H soft surface layer 1 1 is made of a polymer material and then cut and formed, and there will always be waste in the cutting process. The result is 19007 M297732, which increases the production cost. 'At the same time, considering the cost reduction, the soft surface layer π and the sound insulation 10 and the sound insulation 塾 10 and the rubber shell 14 only form a partial adhesion rather than a comprehensive bond. Therefore, when used, the change of the temperature and humidity of the environment easily results in the soft surface layer 11 separating from the soundproofing pad, the 77 on the earthworm or the soundproofing pad 10 is separated from the rubber, and the service life is caused. Unsatisfactory problem. 乂[New content] The purpose of this creation is to provide a cover for earmuffs that can simplify the process and reduce the cost of h. - Clothing & Another purpose of this creation is to provide a kind of It is a cover for earmuffs that is difficult to buckle and can improve patience. It is used for the purpose of providing one oyster catch 1 for the purpose of this creation, and it is necessary to use the adhesive method to reduce the manufacturing cost. The cover for the cover. The mussels are provided for the purpose of achieving the above and other purposes. The creation of the cover is used for the soap: the cover system for creating the earmuffs includes:

The materials of ', x 凡全' can be selected from the conventional ones, and the soundproofing pad can be used to produce a material sufficient to completely bond the sound insulating mat, the covering layer and the plastic shell. The foaming material is in the process of foam molding, 19007 6 M297732 The adhesion of the coating layer and the rubber shell can be. Since the soundproofing pad and the released sand are any people who drink it, the bonding of the Baicha and the plastic shell is required to be 'eight, one shell or the method can effectively stick to the body, so the process and the production cost are reduced, and The system is firmly integrated and firmly bonded, so that the knife and the coating layer and the rubber shell are provided.

U forms the polymer material of the coating layer 20, the sound insulating mat 21 and the rubber shell 22, but it is a conventional one, and therefore will not be further described herein. However, the foaming material forming the sound insulating mat 21 must have sufficient silkiness at the time of foaming to effectively bond the covering layer 20 and the shell 22. Thus, the soundproofing pad is used. The self-contained material is bonded to the coating layer 2Q and the plastic shell 22, which can save the use and cost of adhesive, double-sided adhesive and/or high-frequency bonding, and can simplify the process and improve the manufacturing efficiency. - 'Refer to Fig. 3' which shows the flow of the cover for the earmuff of the present invention. As shown, in step 3, a coating layer 20 is applied to the surface of the mold cavity 230. The coating layer 20 is selected such that the bonding property between the material and the surface of the cavity 23Q of the mold 23 is less than the adhesion between the coating layer and the surface of the cavity 23 of the mold 23, so that at the end of the process, the mold 23 is After being detached from the finished product, the coating layer 2 can be firmly bonded to the sound insulating mat 21 (described in detail below). As shown in FIG. 3B, a casing 22 and a casing 22 opposite to the inner casing surface 221 of the casing surface 220 are attached to the mold 23 to cover the cavity 230 for Subsequent injection operations are carried out. After the plastic shell & to the mold 23, the inner shell surface 221 is directed toward the cavity 23, and the rubber shell 22 is formed with a plurality of injection holes 222 to open the mold cavity 23 to the outside; , the 5th rubber shell 22 is formed with a step portion 223 on the peripheral portion thereof, so that when the rubber shell 22 is attached to the mold 23, the periphery of the cavity 8 19007 M297732 230 can be effectively borrowed from the step portion m is enclosed in the operation, and the periphery of the glue injected into the mold hole = analgesic spills outward. The L material will be connected from the mold hole 230. As shown in Fig. 3C, the foaming material is poured into the mold hole 230, and the hole 222 is poured into the mold hole 230. Foaming in the injection molding to form a sound-insulating mat;;: Sexual material in the mold cavity 230, so after the formation of the Puzhan 91 / Hai foaming material has adhesive injection for f + 忐% with the same material Adhesive, and after the work is completed, the cover layer 2Q is the first #面 of the soundproof mat 21? 1η μ a surface 201 yuan died 'knot to the full 珥 5 5, and the inner shell surface 221 of the plastic shell 22 兀 Wang Bingzhan, 'mouth to the sound insulation hot 21 筮 - form the soundproof mat 21, the main glue On the g, 11 and 达成, and the use of 2 〇, the separation of the 9 industry can be done at the same time to complete the bonding of the coating and the plastic shell 22, so you can omit the lower: the two required The road bonding process can simplify the process and reduce the cost of the heart. In addition, the coating layer 2Q and the rubber shell 22 can completely adhere to each other: the first surface 21 of the sound insulating mat 21 and the second surface 211, the adhesion between the non-layer 20 and the sound insulating mat 21 and the The adhesiveness of the rubber shell 22 and the sound insulating mat 21 ^ is much larger than that of the conventional shell structure, so that the durability of the finished product can be effectively improved. Finally, as shown in Fig. 3D, the mold 23 and the cover 2 formed by combining the coating layer 20, the crucible 21. and the rubber shell 22 are separated in the direction indicated by the arrow in the figure. As described above, since the material selected for the coating layer 20 is such that the adhesion between the surface of the coating layer 23 and the surface of the cavity 23 is less than that of the coating layer 2 and the sound insulating mat, the mold 2 3 is detached from the mold. In the case of the cover 2, the cover 9 19007 M297732 layer 20 does not adhere to the body 2 of the cavity and smoothly detaches. Of course, the mold 23 can also be self-coated: a release agent layer, when the mold is released. = Face Pre-No No: ?
