[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0033] In one embodiment of the present invention, a breathable and soft mold cup is provided. Figure 1 , which comprises a first sponge layer 1, a second sponge layer 2 and a plastic mesh bag 3 disposed between the first sponge layer 1 and the second sponge layer 2, wherein the plastic mesh bag 3 comprises a bag body and fiber sponge 32 contained in the bag body, see Figure 2 and Figure 3 The fiber cotton 32 is elastic, and the bag body is formed by two layers of rubber mesh melt-bonded along the periphery. The rubber mesh is a mesh structure, and the main component of the rubber mesh is TPE, also known as artificial rubber or synthetic rubber, which is a new type of polymer material with viscosity; the shape of the mesh in the rubber mesh is any one or more of circular, elliptical, heart-shaped, triangular, square, rectangular, diamond, star-shaped, polygonal, and irregular shapes. If the mesh is a circular hole, the aperture range is set to 3-4mm, which has good air permeability and no limit on its gram weight.

[0034] The rubber mesh bag is formed by two layers of soft rubber mesh melt-bonded along the periphery, and a filling port 33 is reserved on one side of the bag body for filling high-elastic fiber cotton. When filling the fiber cotton, the filling port does not contain fiber cotton. During high-temperature molding, the two layers of rubber mesh at the filling port are bonded to fix the fiber cotton in the bag body; the filled fiber cotton is formed by multiple soft fiber layers (stacking is a process, just like laying thick cotton wool, laying fibers layer by layer to form a certain thickness), and the fibers are separated from each other, so there is space for air permeability; the fiber cotton is a special ultra-fine polyester chemical fiber material, and the so-called four-hole cotton, seven-hole cotton, nine-hole cotton, and ten-hole cotton on the market are this kind of fiber cotton. No adhesive is added to the fiber cotton, which is in a disordered clumping shape and very soft, greatly improving the wearing comfort. In addition, the PU rubber net is melted by heating and solidified by cooling, which fixes the fiber cotton filled in the rubber net bag. This will not cause the mold cup deformation caused by the displacement of the fiber cotton, thus extending the service life of the mold cup. The softness of the rubber net bag also improves the wearing comfort of this type of mold cup after it is made into a bra.

[0035] In addition, the fibers in the high-elastic fiber cotton can be fibers containing nano-silver particles. Nano-silver particles are added when making the fibers. Nano-silver is a metallic silver element with a diameter less than 100 nanometers, generally 20 to 50 nanometers. Nano-silver is a silver particle composed of an atomic structure, which has a good antibacterial effect and meets the needs of modern women for breathable, comfortable and healthy bras. As the latest generation of natural antibacterial agents, nano-silver particles have the following characteristics: broad-spectrum antibacterial and sterilization without any drug resistance; strong sterilization, which can kill a variety of harmful bacteria to the human body within minutes; strong permeability, can quickly penetrate into the subcutaneous tissue through the pores to sterilize, and has a good sterilization effect on common bacteria, stubborn bacteria, drug-resistant bacteria and infections caused by fungi; promote healing: improve the micro-organisms around the wound, effectively activate and promote the growth of tissue cells, accelerate wound healing, and reduce the formation of scars; antibacterial and lasting, nano-silver particles are produced using patented technology, with a protective film on the outside, which can be gradually released in the human body, so the antibacterial effect is lasting.

[0036] In addition, the thickness range of the plastic mesh bag is set to 10mm-40mm, and the thickness of the entire mold cup can be adjusted by increasing or decreasing the amount of high-elastic fiber cotton.

[0037] The first sponge layer 1 is provided with a first beauty position, see Figure 1 The second sponge layer 2 is provided with a second beauty position which is arranged opposite to the first beauty position, and a space for accommodating the plastic mesh bag 3 is formed between the first beauty position and the second beauty position.

[0038] The first sponge layer 1 and the second sponge layer 2 are both provided with a plurality of punched holes 4. Figure 5 and Figure 6 ( Figure 5 and Figure 6 Although only the first sponge layer is marked, the same applies to the second sponge layer), the air permeability of the mold cup can be improved; there are no punching holes on the first best accumulation cloth 5 and the second best accumulation cloth 6.

[0039] The first sponge layer 1 is provided with a first best accumulation cloth 5 on one side away from the second sponge layer 2, and the second sponge layer 2 is provided with a second best accumulation cloth 6 on one side away from the first sponge layer 1. The best accumulation cloth is made of 100% polyester with a square gram weight of 90g-170g. The best accumulation cloth plays a role in supporting the sponge, is beautiful, and can prevent the sponge from changing color. The best accumulation cloth has a soft feel and can withstand high temperatures of 180-192 degrees Celsius, and is suitable for molded products combined with sponges.

[0040] A first adhesive layer is arranged between the rubber mesh bag 3 and the first sponge layer 1, and the first adhesive layer is sprayed on the side of the first sponge layer away from the first best accumulation cloth; a second adhesive layer is arranged between the rubber mesh bag 3 and the second sponge layer 2, and the second adhesive layer is sprayed on the side of the second sponge layer away from the second best accumulation cloth. Both the first adhesive layer and the second adhesive layer are polyurethane adhesives, which are used to fix the rubber mesh bag 3 between the first sponge layer 1 and the second sponge layer 2; in addition, the rubber mesh bag is also a TPE adhesive, which can play the role of glue bonding, so that the first sponge layer 1, the rubber mesh bag 3 and the second sponge layer 2 are firmly bonded.

[0041] The present invention places a plastic mesh bag filled with high-elastic fiber sponge at the beautiful position of the medium-thick mold cup (the medium mold cup refers to a mold cup with a thickness range of 10-15mm, and the thick mold cup refers to a mold cup with a thickness range of 15-20mm), thereby solving the problem of poor air permeability of the medium-thick cup due to the excessive thickness of the sponge. At the same time, due to the softness of the plastic mesh bag, the wearing comfort of the bra made of such mold cup is improved. Moreover, the addition of silver particle fiber sponge makes the mold cup have antibacterial function, which meets the needs of modern women for breathable, comfortable and healthy bras.
