The present invention relates to a bra cup of a bra, and more particularly, to a bra cup having excellent durability and a light and soft touch.

Bras are women's foundations that wrap the chest around the breast and are also known as bras, uplifts, and bandeaus. The bra supports and protects the breast and corrects the shape of the breast to create the ideal silhouette of the top. The bra is a word from the French brasier.

The basic shape of the bra covers the size of the breasts and covers the shoulders. The bottom of the bra should not stick tightly to the body, but it should be able to afford a little more on the breast. In general, this is necessary for obese people, and in the case of skinny people can be controlled by putting a bracup to make the shape of the chest. And the bra usually needs a strap that is coupled to the bra cup so that the bra cup is fixed to the body while the bra cup is closely attached to the breast.

The bra cup is provided with a cup body for maintaining the shape of the bra cup inside the shell. The cup body is generally used by molding a polyurethane material. As a molding method, a polyurethane material having a certain thickness is pressed by a press to form a bra cup shape.

However, such a bra cup has a relatively small molding amount at the center portion of the thick bra cup, whereas a thin outer portion has a large molding amount. As a result, the outer periphery is formed hard, there is a disadvantage that the overall fit is not good. In addition, the polyurethane material has a disadvantage in that the flexibility of the material itself.

In order to solve this problem, research on bra cups formed of more flexible, lighter and more environmentally friendly materials such as latex has been continued. However, all of these materials are weak in durability, and are difficult to manufacture and cannot be used for a long time even when the product is completed. There is this.

The present invention has been made to solve the above problems, an object of the present invention is to provide a bra cup with excellent durability and light and soft touch.

The present invention, in order to achieve the object as described above, has a bra cup shape, the inner tension member having durability against tensile force; And a latex layer applied to the inner tensile member. Therefore, while utilizing the light and soft characteristics of the latex, it is also provided with durability.

Here, the latex layer, the inner latex layer applied to the inside of the inner tensile member; And an outer latex layer applied to the outside of the inner tensile member.

In addition, it is effective that the inner tensile member is formed in a mesh shape.

In addition, the latex layer is preferably formed in a thin outer peripheral surface. Therefore, the boundary between the cup and the married woman is not easily exposed to the outside of the clothes.

On the other hand, according to another field of the present invention, the step of placing the inner tension member for positioning the inner tension member between the upper mold and the lower mold protruding the shape of the bra cup upper portion recessed; Contacting the upper mold and the lower mold to form a bra-shaped space; A latex injection step of injecting a liquid latex into the bra-shaped space; And a separation step of separating the bra cup solidified from the mold. It provides a bra cup manufacturing method comprising a.

Here, after the latex injection step, the upper mold and the lower mold further contact step; further preferably comprises a. Therefore, not only can the durability of the cup be further increased, but also the surface of the cup can be made smoother.

After the separation step, the separated latex is washed with an antioxidant. Therefore, discoloration of the cup color can be prevented.

In addition, the inner tension member arrangement step, it is preferable to include; fixing the outer periphery of the inner tension member. Therefore, the inner tensile member can be prevented from being wrinkled.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a bra of a first embodiment of the present invention.

As shown in these figures, generally the most commonly used bras are two bra cups 100 formed to surround the wearer's breasts, a chest connection part 200 connecting to the chest of the bra cup 100, and a bra Back connection part 300 for connecting the back side of the cup 100, one end is composed of a shoulder strap 400 is connected to the upper end of the bra cup 100 and the other end is connected to the back connection part (300).

Since the feature of the present invention is in the bra cup 100, hereinafter will be described in detail with respect to the bra cup 100, and other parts are well-known parts so that the detailed description thereof does not obscure the subject matter of the present invention. Is omitted.

2 is a cross-sectional view taken along the line II-II of FIG. 1.

As shown, the bra cup 100 is composed of a bra cup body 120 in the shape of a bra cup, and an outer shell 110 coupled to the surface of the bra cup body.

The bra cup body 120 includes an inner tensile member 123 having durability against tensile force, and latex layers 121 and 122 applied to the inner tensile member 123. The inner tensile member 123 is formed in a mesh shape, the material may be used a variety of materials. That is, natural natural and synthetic materials, such as cotton or silk fabrics, mesh, or the like may be used.

The latex layers 121 and 122 are composed of an inner latex layer 122 applied inside the inner tension member 123 and an outer latex layer 121 applied outside the inner tension member 123. In FIG. 2, the inner tension member 123 is located exactly at the middle portion between the inner latex layer 122 and the outer latex layer 121, but is not necessarily positioned at the middle portion, and may be biased toward either side. That is, even if the latex layer is applied to only one surface of the inner tensile member 123 is within the scope of the present invention.

The latex layers 121 and 122 are formed thin in the outer circumference. Therefore, not only is it easy to combine with the outer shell, but also prevents the boundary between the skin and the bra cup from protruding from the garment.

Sheath 110 is composed of an inner sheath 112 coupled to the inner latex layer 122 and an outer sheath 111 coupled to the outer latex layer 122. The outer shell 110 may be used as an outer shell material generally used for a bra such as a cotton material or a silk fabric having a good contact feeling. The outer shell 110 and the bra cup body 1120 are coupled to the outer periphery of the bra cup body 120 and the outer shell 110 by sewing. However, the present invention is not limited thereto and may be combined by various coupling methods.

Latex is a natural latex, a sticky liquid that exudes gold with a knife on the bark of Hevea brasiliensis grown around the Malay Peninsula, and a synthetic latex made by emulsion-polymerizing synthetic rubber. Latex is light, environmentally friendly and has a good texture and is being applied in various fields as a well-being material. However, the latex itself was poor in durability and could not be used as a material for bra cups. In particular, the outer skin 100 and the sewing seam site could be easily torn. The present invention can be solved by placing the tension member 123 in the latex. That is, the tension member 123 supports the tension force, thereby preventing the latex material from tearing.

3 and 4 show the structure of the second embodiment of the present invention, Figure 3 is an exploded perspective view of the bra, Figure 4 is a cross-sectional view taken along the line IV-IV of FIG.

Unlike the first embodiment, the bra of the second embodiment is a bra with back and shoulder connections removed. This type of brayer is for wearing clothes with exposed shoulders or backs.

The bra of the second embodiment includes two bra cups 500 formed to surround a wearer's breast, a chest connection part 200 connecting to the chest of the bra cup 500, and an inner surface of the bra cup 500. A detachable adhesive is applied to the adhesive layer 530, and the outer surface 510 of the flocked bra cup.

The bra cup 500 is composed of an inner tension member 523 and latex layers 521 and 522 applied to the inner tension member 523. The inner tensile member 523 is formed in a mesh shape, the material may be used a variety of materials. That is, natural natural and synthetic materials, such as cotton or silk fabrics, mesh, or the like may be used.

The latex layers 521 and 522 are composed of an inner latex layer 522 applied inside the inner tension member 523 and an outer latex layer 521 applied outside the inner tension member 523. In FIG. 4, the inner tensile member 523 is located exactly at the middle portion between the inner latex layer 522 and the outer latex layer 521, but is not necessarily positioned at the middle portion, and may be biased toward either side.

Latex layers 521 and 522 are thinly formed on the outer circumference. Therefore, the boundary between the skin and the bra cup does not protrude out of the clothes.

Although the adhesive layer 530 is not shown in thickness on FIG. 4, a detachable adhesive that is harmless to a human body is used on the inner surface of the bra cup. The outer side surface 510 is made of a hair material, or by attaching a thin fiber yarn to the outer side surface 510, a flocking effect can be obtained.

As described above, even when the bra of the second embodiment uses latex, a light and soft texture can be obtained, it is possible to prevent the bra cup from being easily torn due to the internal tension member.

5 to 7 is a cross-sectional view showing a step-by-step method of manufacturing a bra cup of the present invention.

The mold used to manufacture the bra cup of the present invention consists of an upper mold 720 and a lower mold 710.

The upper mold 720 includes a concave indentation surface 723 in which the upper portions of the bra cups 100 and 500 are concave, a stock solution outflow prevention jaw 722 formed to protrude from the lower outer peripheral surface of the concave inlet surface 723, and a concave intake surface ( And a material inlet 721 formed through the 723. The stock solution leakage preventing jaw 722 may be formed of an elastic material or may be coupled to the inside of the upper mold 720.

The lower mold 710 is combined with a protrusion 712 protruding from the lower portion of the bra cup, and a fixing member 711 capable of fixing the outer circumference of the inner tension member 123 to the outer circumference of the protrusion 712. The fixing member 711 may be formed in a screw fastening structure.

Using these molds 710 and 720, a method of manufacturing a bra cup includes a step of arranging an inner tension member for positioning the inner tension member 123 between the upper mold 720 and the lower mold 720; Tensioning the outer circumferential portion of the inner tensile member 123 and fixing it to the fixing member 711 (FIG. 5), and closely contacting the upper mold 720 and the lower mold 710 to form a bra-shaped space ( 6), a latex injection step (FIG. 6) for injecting latex into the bra-shaped space, a pressing step (FIG. 7) for further contacting the upper mold 720 and the lower mold 710, and a mold 710 A separation step of separating the solidified bra cup 120 at 720 and washing the separated latex with an antioxidant.

The reason for fixing the inner tensile member 123 to the fixing member 711 is to apply a certain tensile force to the inner tensile member 123, to prevent the occurrence of wrinkles when formed into a curved surface.

In the latex injection step, a foam molding process is used to generate bubbles in the mold.

In the step of washing in the antioxidant, the bra cup 120 is washed in a solution in which hydrogen peroxide and sodium hydroxide are mixed. By doing so, oxidation of the latex material can be prevented, and the surface of the latex can be prevented from yellowing. Therefore, it is possible to implement a white bra cup that can not be implemented in the bra cup of the conventional polyurethane material, a more advanced design is possible.

As described above, the manufacturing method does not compress the material or compresses the same amount even if there is, so that the outer peripheral portion is formed much smoother than the method of compression molding a material such as a conventional polyurethane. Therefore, the fit of the bra cup is much better than before.

According to the embodiment of the present invention as described above, various effects including the following matters can be expected. However, the present invention is not achieved by exerting all of the following effects.

First, the bra cup according to the present invention may have durability even when using a soft material such as latex by having an inner tension member therein.

In addition, since the outer circumference of the bra cup may be soft and thin, the fit of the bra is good and the boundary of the bra is not exposed to the outside.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope of the claims.
