1 is a perspective view schematically showing a brassiere with a bra cup according to an embodiment of the present invention.

1, a brassiere 100 to which a bra cup 400 of the present embodiment is applied includes a pair of bra cups 400 that can wrap both breasts of a woman, And a shoulder strap 170 coupled to an upper end of the bra cup 400. The left and right band parts 160 are connected to each other and connect the pair of bra cups 400 to each other.

At this time, the left and right band portions 160 are connected to each other by the fastening means 161. The fastening means may be a hook or the like. The fastening means 161 includes two or three pairs of upper and lower two, or two or three pairs of three, such that the fastening means 161 is fastened to fit the body of the wearer so that the bracket 100 is loosened or flowed down when the bra 100 is worn Or too tightly tightened.

2 is a side cross-sectional view schematically showing a bra cup according to an embodiment of the present invention.

2, the bra cup 400 according to the present embodiment includes a first cup portion 410 having a first concave portion 411 formed on an inner surface thereof to enclose a breast, a second cup portion 410 having an outer surface of the first cup portion 410, And a second cup part 420 having a second concave part 421 on the inner surface so as to cover and cover the first projection part 412 of the first cup part 410. [

The outer surface of the second cup part 420, that is, the second projecting part 422 of the second cup part 420 is formed to have a relatively large curved surface as compared with the first recessed part 411 of the first cup part 410 .

For example, the first concave portion 411 of the first cup portion 410 surrounding the breasts may be A (small) or B (middle) cup size, and the second protrusion 422 ) May be C (large) cup size. Therefore, when a female having a relatively small size body with a chest size of A or B cup size wears a bra equipped with the bra cup 400 of the present embodiment, the second projecting portion of the first cup portion 420 422 can provide a sense of volume of the C cup size. At this time, there is no particular limitation on the thickness of the first and second cup portions 410 and 420, but they are preferably formed to have different thicknesses. For example, since the first cup portion 410 has a smaller curvature than the second cup portion 420, the first cup portion 410 can be formed to be thinner than the second cup portion 420 because the relatively unfolding force is strong. In this case, if the thickness of the first cup portion 410 is 1, the thickness of the second cup portion 420 may be 1.2 to 1.5 times the thickness of the first cup portion 410. If it is less than 1.2, it is difficult to effectively prevent the first cup portion 410 from spreading during long-time use. If it is larger than 1.5, the first cup portion 410 becomes too thin.

The bra cup 400 configured as described above has a first cup portion 410 having a first concave portion 411 of A or B cup size that matches the size of its own breast, It is able to wear comfortably without nipple or breast pressure by naturally wrapping breasts while stably collecting, supporting and protecting the wearer's breast.

In addition, the outside of the bra cup 400 is formed of the second cup part 420 having the second protruding part 422 showing a natural and beautiful C cup size chest line, so that aesthetic volume up can be achieved without a separate volume up auxiliary pad This makes it possible to beautifully dress clothes when wearing clothes.

Therefore, it is possible to make aesthetic volume-up by eliminating the inconvenience felt by women wearing a C cup-sized bra which is larger than the size of their bosom in order to correct the body shape, It is effective.

In the present embodiment, the shape of the bra cup 400 is illustrated as a full cup shape, but the present invention is not limited thereto. If necessary, the bra cup of the present invention may be changed into various shapes such as a half cup or a 3/4 cup Of course.

On the other hand, in the case of a volume up bra to insert a conventional pad, these pads pressurized the nipple to cause pain or deformation of the breast. However, in this embodiment, a nipple insertion groove 411a may be formed in the first concave portion 411 of the first cup portion 410 to insert the tip portion of the nipple into the first concave portion 411 as needed. In addition to comfort, it reproduces the most ideal breast shape in three dimensions and further suppresses the pressure of the nipple, so it can support the shape of the breast more comfortably and fix it beautifully while maintaining the exact shape and size of the wearer.

3 and 4, the bra cup manufacturing apparatus according to the present embodiment includes a lower mold 210 having a cup-forming projection 211 on its upper surface and an upper mold 210 having a cup- 220).

The lower mold 210 may include a heating member such as a heating coil (not shown) inside the body. The heating coil heats the first and second pads 310 and 320 disposed on the lower mold 210 to a predetermined temperature. The first and second pads 310 and 320 may be made of an elastic filler such as a sponge having elasticity of a predetermined level or more, but the present invention is not limited thereto. At this time, the first and second pads 310 and 320 may preferably be formed to have the same thickness.

At this time, a nipple insertion groove-forming protrusion 211a may be formed on the cup-forming protrusion 211 of the lower mold 210.

Further, the cup forming groove 221 may have a relatively large curved surface compared to the cup forming projection 211. For example, the cup forming protrusion 211 of the lower mold 210 may be A or B cup size, and the cup forming groove 221 of the upper mold 220 may be a C cup size.

The bra cup 400 according to the present embodiment is configured such that the first and second pads 310 and 320 are sequentially stacked on the lower mold 210 and then the upper mold 320 is pressed, And fused.

At this time, the first pad 310 has a first cup portion 411 having a first concave portion 411 and a first projection portion 412 on the outer surface to comfortably and comfortably cover the breast, 410 and the second pad 320 is formed by covering the first protrusion 412 of the first cup portion 410 with respect to the second concave portion 421 and the first concave portion 411 which are fusion- The second cup portion 420 having a relatively large cup side and having a second protrusion 422 on the outer surface that can provide a volume up effect of a natural bust line.

bra  How to make a cup

Fig. 5 is a flowchart sequentially showing a method of manufacturing a bra cup according to an embodiment of the present invention.

A method of manufacturing a bra cup using the bra cup producing apparatus of the present embodiment will be described with reference to Fig.

First, first and second pads 310 and 320 formed of a material such as a sponge are provided. The first and second pads 310 and 320 may have the same thickness, but the present invention is not limited thereto. The first and second pads 310 and 320 may have different thicknesses . For example, since the first pad 310 has a smaller curvature than the second pad 320, the first pad 310 may be relatively thinner than the second pad 320. In this case, when the thickness of the first pad 310 is 1, the thickness of the second pad 320 may be 1.2 to 1.5 times the thickness of the first pad 310.

In the present embodiment, the pad for forming the cup portion is used by overlapping two first and second pads 310 and 320. This is because when the first and second pads 310 and 320 have different curvatures of the first and second pads 310 and 320 and are used as one pad, it is difficult to maintain the first and second cup portions as they are during long- In addition, when one pad is used, the expansion and contraction of the fabric surrounding the pad and the pad are different, so that the pad of the sponge material stretches as much as the stretching of the fabric, and the shape of the desired cup portion can not be realized properly. In particular, when using the A cup on the inside and the C cup on the outside, the thickness of the pad used is considerable. In this case, two pads must be used.

The first and second pads 310 and 320 may have different densities. This is because the first cup portion 410 inside the bra cup needs to maintain softness as the first concave portion 411 touches the chest directly and the second cup portion 420 on the outside of the bra cup has the second protrusion (422) is required to be formed so as to be harder than the first cup part (410) as a part for keeping the outer shape of the chest alive and keeping the dressing beautifully.

For example, the second pad 320 may use a material having a density of 1.5 to 3 times that of the first pad 310. The second protrusion 422 of the second cup portion 420 hardly alters the external shape of the chest when the second pad 320 has a density less than 1.5 as compared with the first pad 310. The second pad 320 Is too hard compared to the first pad 310 to have a density of more than three times, the first cup portion 410 is not integrated properly.

At this time, the first pad 310 may use a soft low-carbon material, and the second pad 320 may use a general sponge or a memory foam. However, the present invention is not limited thereto, and the materials of the first and second pads of the present invention may be changed within the scope of the present invention.

Next, the first and second pads 310 and 320 are placed on the lower mold 210 having the cup-shaped protrusions 211 on the upper surface thereof (S100).

Next, an upper mold 220 having a relatively large curved cup-shaped groove 221 as compared with the cup-shaped protrusion 211 is pressed above the second pad 320, The first and second pads 310 and 320 are formed into a cup shape at a temperature of 200-220 ° C for 1 minute to 1 minute and 30 seconds through a heat generating member while performing a first heat fusion (S200).

At this time, the cup-shaped groove 221 may have a relatively large curved surface as compared with the cup-shaped projection 211. For example, the cup-shaped protrusion 211 of the lower mold 210 may be the A or B cup size, and the cup-shaped groove 221 of the upper mold 220 may be the C cup size. Accordingly, the first pad 310 that is thermally fused is formed into a first cup portion 410 having a first concave portion 411 of A or B cup size, and the second pad 320 which is thermally fused is formed into a C cup size The second cup portion 420 having the second convex portion 422 of the second cup portion 420 is formed.

Next, after separating the upper mold 220 from the lower mold 210, the first and second pads 310 and 320 are exposed to room temperature for about one minute to cool temporarily (S300).

Next, the upper mold 220 is pressed again to the upper side of the second pad 320, and the lower mold 220 is secondarily thermally fused at 170 to 185 ° C for 1 minute, 30 seconds to 2 minutes to complete the bra cup 400 (S400) .

Generally, sponge is composed of rubber component and is sensitive to chemical and physical reaction. If exposed to humidity or light for a long time, it may smell, deform shape and color may change. Even if sponges of the same composition are used, the molding temperature and time may be different depending on the density.

In addition, the sponge may change its elasticity and elasticity by heat, and its shape may change during the cooling process. That is, when molding is performed at a high temperature for a short period of time, the outer appearance may be wrinkled and hardened, and molding at a low temperature for a long time may make it difficult to realize a desired shape.

The first and second pads 310 and 320 made of a sponge having a predetermined thickness are attached to the first and second pads 310 and 320 through the first heat fusion process, 310, and 320 to be fixed in the form of the first and second cup portions.

Then, the first and second pads 310 and 320 are exposed to room temperature for cooling, and then subjected to secondary heat fusion so that a desired shape in design can be properly realized. In addition, It is possible to prevent the first and second pads 310 and 320 from being wrinkled and changing color due to heating. In particular, it is possible to prevent the first and second pads 310 and 320 from being hardened, and maintain the softness of the portion contacting the skin at a certain level.

In this case, the secondary heat fusion can preferably proceed at a lower temperature than the primary heat fusion for a longer time, but the present invention is not limited thereto.

The present invention is not limited to the above-described embodiment and the accompanying drawings, but is intended to be limited by the appended claims.

It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. something to do.
