Description

A 3-partition mold for emboding wire function without wire and method for manufacturing brassiere using the same}

The present invention relates to a three-part mold without a wire implementing a wire function and a bra manufacturing method using the same.

A bra is a type of women's underwear and is configured to include a dome-shaped pad cup. Accordingly, by accommodating the breast part through the pad for women, it is possible to protect the breast and prevent sagging at the same time.

In a conventional bra, a wire is inserted into a portion of the periphery of the pad so that the shape of the pad is not disturbed. However, since the wire is formed of a metal or silicon material, it may cause an uncomfortable wearing feeling, or when the wire protrudes out of the pad, it may cause a contact allergy to the skin. In addition, when the bra is used for a long period of time, the wire has a problem in that it is difficult to maintain the shape of the pad because the shape is deformed.

Accordingly, in recent years, a wireless (Wireless) bra has been developed. However, in the case of a general wireless bra, the power to support the lower part of the chest is insufficient, and thus the function of correcting the shape of the chest or increasing the volume is insufficient. In addition, since there is no separate structure for maintaining the shape of the wireless bra, there is a problem in that the pad spreads to both sides or it is difficult to maintain the shape.

In addition, the conventional wireless bra does not include a metal wire, and there are many cases where a wire made of a hard material such as silicon or plastic is attached, so that there is still a problem in wearability.

Therefore, in the development of a wireless bra with improved wearing comfort because there is no wire of any material, there is a demand for the development of a wireless pad that can easily maintain the shape of the pad while correcting the shape of the chest with volume.

Referring to FIG. 1 , a three-part mold (hereinafter, three-part mold) 100 without a wire implementing a wire function according to some embodiments of the present invention includes an upper mold 110 and a lower mold 120 . .

The upper mold 110 and the lower mold 120 may be disposed to face each other. Also, the upper mold 110 may be coupled to the lower mold 120 .

The upper mold 110 may press the pad member 130A. Specifically, when the upper mold 110 moves in the direction of the lower mold 120 , the upper mold 110 may press the pad member 130A in the direction of the lower mold 120 . Accordingly, the pad member 130A may be bent along the shapes of the upper mold 110 and the lower mold 120 .

The upper mold 110 and the lower mold 120 may mold the pad member 130A. The upper mold 110 and the lower mold 120 receive heat through the power supply and pressurize it, so that the pad member 130A is molded according to the shapes of the upper mold 110 and the lower mold 120 . Accordingly, the outer shape of the pad member 130A may be formed along the shape of the concave portion 121 of the lower mold 120 , and the inner shape may be formed along the shape of the convex portion 111 of the upper mold 110 . have.

2A and 2B , the upper mold 110 includes a convex portion 111 . The convex portion 111 of the upper mold 110 may be convex in the direction of the lower mold 120 .

The convex portion 111 of the upper mold 110 includes a central pattern 111a and a plurality of three-dimensional patterns 111b, 111c, and 111d.

The central pattern 111a may be disposed at the center of the convex part 111 to form a curvature of the convex part 111 .

The plurality of three-dimensional patterns 111b, 111c, and 111d may be disposed to surround a portion of the periphery of the central pattern 111a. That is, the plurality of three-dimensional patterns 111b, 111c, and 111d may have curves that partially overlap the central pattern 111a.

The plurality of three-dimensional patterns 111b, 111c, 111d includes a first three-dimensional pattern 111b positioned inside the upper mold 110, a second three-dimensional pattern 111c positioned on one side of the first three-dimensional pattern 111b, and A third three-dimensional pattern 111d positioned on one side of the second three-dimensional pattern 111c may be included.

In this case, the third three-dimensional pattern 111d may be formed on a side opposite to the side on which the first three-dimensional pattern 111b is formed based on the second three-dimensional pattern 111c. That is, the plurality of three-dimensional patterns 111b, 111c, and 111d are formed in which the first three-dimensional pattern 111b, the second three-dimensional pattern 111c, and the third three-dimensional pattern 111d are sequentially arranged from the inside of the upper mold 110 . can

The plurality of three-dimensional patterns 111b, 111c, and 111d include first curves 111ba, 111ca, and 111da. The first curves 111ba, 111ca, and 111da may include a first_1 curve 111ba, a first_2 curve 111ca, and a first_3 curve 111da.

Specifically, the first three-dimensional pattern 111b includes the first_1 curve 111ba, the second three-dimensional pattern 111c includes the first_2 curve 111ca, and the third three-dimensional pattern 111d includes the first_3 curve (111da) may be included. In this case, the first curves 111ba, 111ca, and 111da may be curves in which some of the curves forming each of the plurality of three-dimensional patterns 111b, 111c, and 111d overlap the central pattern 111a.

The first portion 111ba_1 of the first curve 111ba of the first three-dimensional pattern 111b and the first portion 111ca_1 of the first_2 curve 111ca of the second three-dimensional pattern 111c may overlap. In addition, the second portion 111ca_2 of the first_1 curve 111ba of the first three-dimensional pattern 111b that does not overlap with each other and the second portion 111ca_2 of the first_2 curve 111ca of the second three-dimensional pattern 111c are They may extend in different directions.

For example, when the second portion 111ca_2 of the first curve 111ba of the first three-dimensional pattern 111b extends toward the inner side of the upper mold 110, the first_2 of the second three-dimensional pattern 111c The second portion 111ca_2 of the curved line 111ca may extend toward the outside of the upper mold 110 .

The second three-dimensional pattern 111c further includes a second curve 111cb overlapping a portion of the first_3 curve 111da of the third three-dimensional pattern 111d. The second curve 111cb of the second three-dimensional pattern 111c may completely overlap the first portion 111da_1 of the first_3 curve 111da of the third three-dimensional pattern 111d.

The second portion 111da_2 of the first_3 curve 111da of the third three-dimensional pattern 111d that does not overlap the second curve 111cb of the second three-dimensional pattern 111c may overlap the central pattern 111a. . In this case, the second portion 111da_2 of the first_3 curve 111da of the third three-dimensional pattern 111d may extend in the same direction as the first_2 curve 111ca of the second three-dimensional pattern 111c.

For example, when the first_2 curve 111ca of the second three-dimensional pattern 111c extends toward the outer side of the upper mold 110 , the second of the first_3 curve 111da of the third three-dimensional pattern 111d The portion 111da_2 may also extend toward the outer side of the upper mold 110 .

That is, the extending direction of the first_1 curve 111ba of the first three-dimensional pattern 111b, the extending direction of the first_2 curve 111ca of the second three-dimensional pattern 111c, and the first_1 curve 111b of the first three-dimensional pattern 111b 111ba) and the extending direction of the first_3 curve 111da of the third three-dimensional pattern 111d may be different directions.

For example, the first three-dimensional pattern 111b serves to gather the breasts from the inside in the direction of the central pattern 111a, and the second three-dimensional pattern 111c moves the breasts from the lower side toward the central pattern 111a. It functions to gather, and the third three-dimensional pattern 111d functions to gather the chest from the outside in the direction of the central pattern 111a.

In this case, when the extending direction of the first_2 curve 111ca of the second three-dimensional pattern 111c is the same as the extending direction of the first_1 curve 111ba of the first three-dimensional pattern 111b, the second three-dimensional pattern 111c The 1_2 curve 111ca may be convex toward the outside of the convex portion 111 . In this case, as the second three-dimensional pattern 111c changes the direction of supporting the breast toward the outside, the function of gathering the breast toward the center is reduced, and thus, the breast correction effect and the body correction function can be reduced. have.

Similarly, when the extending direction of the first_3 curve 111da of the third three-dimensional pattern 111d is the same as the extending direction of the first_1 curve 111ba of the first three-dimensional pattern 111b, the third three-dimensional pattern 111d The first_3 curve 111da may be convex toward the outside of the convex portion 111 . In this case, in the third three-dimensional pattern 111d, as the direction of supporting the breast is changed from the center to the outside, the function of gathering the breast toward the center is reduced, and thus the chest correction effect and body correction function are reduced can do it

Accordingly, the extending direction of the first_1 curve 111ba of the first three-dimensional pattern 111b is different from the extending direction of the first_2 curve 111ca of the second three-dimensional pattern 111c, and the second three-dimensional pattern 111c is formed differently. By forming the 1_2 curve 111ca of , and the 1_3 curve 111da of the third three-dimensional pattern 111d in the same extending direction, the breast correction effect and body shape correction function may be further improved.

In addition, as shown in FIGS. 8b and 10a, when the pad 130C is manufactured through the three-part mold 100 of the present invention, the direction of supporting the breast through the plurality of three-dimensional patterns 111b, 111c, 111d is the center By facing the , the chest correction effect can be maximized, and the pad 130C to which a multifaceted and three-dimensional body correction function is added can be manufactured.

On the other hand, the curvature of the first_2 curve 111ca of the second three-dimensional pattern 111c is smaller than the curvature of the first_1 curve 111ba of the first three-dimensional pattern 111b, and the first_3 curve of the third three-dimensional pattern 111d 111da) may be greater than the curvature.

For example, a correction force required for each of the plurality of three-dimensional patterns 111b, 111c, and 111d may be different according to a position where it is formed. That is, the first three-dimensional pattern 111b is located closest to a location where the breasts are to be gathered (hereinafter, referred to as the center), and the third three-dimensional pattern 111d is formed at a location farthest from the center. Accordingly, the curvature of the first_3 curve 111da of the third three-dimensional pattern 111d must be formed to be relatively small to cover a wider area than the first three-dimensional pattern 111b or the second three-dimensional pattern 111c, Accordingly, the correction force for supporting the breast from the outside toward the center through the third three-dimensional pattern 111d may be improved.

Accordingly, the curvature of the first_3 curve 111da of the third three-dimensional pattern 111d is the curvature of the first_2 curve 111ca of the second three-dimensional pattern 111c or the first_1 curve 111ba of the first three-dimensional pattern 111b. It should be formed relatively smaller than the curvature of

Similarly, since the second three-dimensional pattern 111c is formed at a position farther from the center than the first three-dimensional pattern 111b, the curvature of the first_2 curve 111ca of the second three-dimensional pattern 111c also corresponds to the first three-dimensional pattern 111b. It is formed to be smaller than the curvature of the first_1 curve 111ba of , so that the second three-dimensional pattern 111c can support the breast in a wider area than the first three-dimensional pattern 111b.

In addition, as shown in FIGS. 8B and 10A , when the pad 130C is manufactured through the three-part mold 100 of the present invention, each of the plurality of three-dimensional patterns 111b, 111c, 111d has different curvatures at different positions. As it is formed with , it is possible to have different correction forces at each position, and thus, it is possible to manufacture the pad 130C to which a more multifaceted and three-dimensional body correction function is added.

Meanwhile, in FIGS. 1 to 5B , the plurality of three-dimensional patterns 111b, 111c, and 111d formed on the convex portion 111 of the upper mold 110 are illustrated as three, but the present invention is not limited thereto. The plurality of three-dimensional patterns 111b, 111c, and 111d may be four or more.

3A and 3B , the lower mold 120 includes a concave portion 121 . The concave portion 121 of the lower mold 120 may be formed to completely surround the convex portion 111 of the upper mold 110 when the upper mold 110 is coupled. That is, the curvature of the concave portion 121 of the lower mold 120 may be smaller than the curvature of the convex portion 111 of the upper mold 110 .

4 to 5b, when the upper mold 110 and the lower mold 120 are combined, a plurality of three-dimensional patterns 111b, 111c, 111d of the upper mold 110 and the concave portion of the lower mold 120 An air gap AG is formed between the 121 .

Specifically, the concave portion 121 of the lower mold 120 may be formed to surround the convex portion 111 of the upper mold 110 . In this case, in the convex portion 111 of the upper mold 110 , the convexity of the central pattern 111a may be greater than the convexity of the plurality of three-dimensional patterns 111b, 111c, and 111d. Accordingly, when the upper mold 110 and the lower mold 120 are coupled, the central pattern 111a of the concave part 121 of the lower mold 120 and the convex part 111 of the upper mold 110 corresponds to each other. A space may be formed between the concave portion 121 of the lower mold 120 and the plurality of three-dimensional patterns 111b, 111c, and 111d of the convex portion 111 of the upper mold 110. have.

Hereinafter, a method of manufacturing a bra according to some embodiments of the present invention will be described with reference to FIGS. 6 to 11B . For convenience of description, FIGS. 1 to 5B may be referred to together.

First, referring to FIG. 7A , a pad member 130A is formed by stacking a first member 130A_1 , a second member 130A_2 , and a third member 130A_3 ( S110 ).

The pad member 130A is made of a synthetic resin that can be deformed by heating and pressing, and may be molded by the upper mold 110 and the lower mold 120 .

The pad member 130A includes a first member 130A_1 , a second member 130A_2 , and a third member 130A_3 .

The first member 130A_1 may be disposed outside the pad 130C to form an outer shape of the pad 130C. Also, the first member 130A_1 may form the outer shape of the pad 130C when the pad 130C is formed. Accordingly, the first member 130A_1 may be made of a material having a hardness capable of maintaining the external shape of the pad 130C.

The second member 130A_2 may be disposed on one side of the first member 130A_1 . The second member 130A_2 may be made of a material that is harder than the first member 130A_1 and has elasticity. Accordingly, the second member 130A_2 can be easily deformed in shape according to the shape of the chest and can stably support the chest. For example, the second member 130A_2 may be made of polyurethane, but the present invention is not limited thereto.

The third member 130A_3 may be disposed on one side of the second member 130A_2 . The third member 130A_3 may be disposed on the innermost side of the pad 130C to form an endothelium of the pad 130C. Since the third member 130A_3 is a member in direct contact with the user's body, it may be made of a material softer to the touch than the first member 130A_1 or the second member 130A_2 .

Then, referring to FIG. 7B , the pad member 130A is disposed between the upper mold 110 and the lower mold 120 ( S120 ). In this case, the pad member 130A may be disposed such that the first member 130A_1 faces the lower mold 120 .

Then, referring to FIG. 7C , the pad member 130A is molded ( S130 ).
Specifically, the upper mold 110 may be configured to move in a direction perpendicular to the lower mold 120 through the hydraulic frame 140 . Accordingly, when molding the pad member 130A, the upper mold 110 is moved in the lower mold 120 direction so that the convex part 111 of the upper mold 110 is accommodated in the concave part 121 of the lower mold 120 . can be moved to At this time, as the upper mold 110 and the lower mold 120 are coupled to each other, the upper mold 110 may press the pad member 130A, and thus, the pad member 130A is formed by the upper mold 110 and It may be molded according to the shape of the lower mold 120 .

Next, referring to FIGS. 8A to 9B , a plurality of pad patterns are formed on the molded pad member 130B ( S140 ).

Specifically, when the upper mold 110 presses the pad member 130A, the pad member 130A is molded and a plurality of three-dimensional patterns 111b, 111c, and 111d corresponding to the plurality of three-dimensional patterns 111b, 111c, and 111d of the upper mold 110 are molded inside. of pad pattern may be formed.

The plurality of pad patterns may include a first pad pattern 130B_1 , a second pad pattern 130B_2 , and a third pad pattern 130B_3 . Each of the plurality of pad patterns may be formed at a position corresponding to each of the plurality of three-dimensional patterns 111b, 111c, and 111d.

For example, the first pad pattern 130B_1 may be formed at a position corresponding to the first three-dimensional pattern 111b, and the second pad pattern 130B_2 may be formed at a position corresponding to the second three-dimensional pattern 111c. In addition, the third pad pattern 130B_3 may be formed at a position corresponding to the third three-dimensional pattern 111d.

That is, the first pad pattern 130B_1 may be formed inside the molded pad member 130B, the second pad pattern 130B_2 may be formed on one side of the first pad pattern 130B_1 , and the third pad pattern Reference numeral 130B_3 may be formed on the opposite side of the second pad pattern 130B_2 on which the first pad pattern 130B_1 is formed.

The conventional wireless bra lacks the power to support the lower part of the chest, and lacks the functionality of correcting the shape of the chest or increasing the volume. In addition, since there is no separate structure for maintaining the shape of the wireless bra, there is a problem in that the pad spreads to both sides or it is difficult to maintain the shape.

However, the pad 130C manufactured through the three-part mold 100 according to some embodiments of the present invention is a pad 130C through a plurality of three-dimensional patterns 111b, 111c, 111d of the upper mold 110 . By forming the pattern, the chest correction function can be improved, and the shape of the pad 130C can be easily maintained.

Specifically, a plurality of pad patterns may be formed on the pad 130C manufactured through the three-part mold 100 of the present invention. Since the plurality of three-dimensional patterns 111b, 111c, and 111d formed on the upper mold 110 are three-divided patterns, the plurality of pad patterns may be formed in three divisions to correspond thereto. That is, the plurality of pad patterns may include a first pad pattern 130B_1 , a second pad pattern 130B_2 , and a third pad pattern 130B_3 .

Accordingly, the inner side of the chest can be supported through the first pad pattern 130B_1 , the lower part of the breast can be supported through the second pad pattern 130B_2 , and the outer side of the chest can be supported through the third pad pattern 130B_3 . As it is supported, it is possible to reduce the chest from leaving the pad 130C, and thus, the chest can be gathered to the central portion of the pad 130C, thereby having the effect of correcting the volume of the chest.

Referring back to FIGS. 8A to 9B , each of the plurality of pad patterns may have a volume. Specifically, the volume of each of the plurality of pad patterns is an air gap ( AG) and the corresponding volume.

For example, the volume of the first pad pattern 130B_1 may have a volume corresponding to the air gap AG1 between the concave portion 121 and the first three-dimensional pattern 111b, and the second pad pattern 130B_2 may have a volume. The volume of may have a volume corresponding to the air gap AG2 between the concave portion 121 and the second three-dimensional pattern 111c, and the volume of the third pad pattern 130B_3 may be equal to that of the concave portion 121 and the third pad pattern 130B_3. It may have a volume corresponding to the air gap AG3 between the three-dimensional patterns 111d.

When the bra pad 130C is manufactured through the three-part mold 100 of the present invention, each of the plurality of pad patterns is formed to have a volume, so that an elastic force according to the volume is generated in the pad 130C, so that the wireless The shape deformation of the brassiere can be reduced. That is, the first pad pattern 130B_1 is formed inside the pad 130C to reduce the pad 130C from being spread outward, and the second pad pattern 130B_2 is formed below the pad 130C. Thus, it is possible to reduce the spread of the pad 130C to both sides, and the third pad pattern 130B_3 is formed on the outside of the pad 130C to reduce the spread of the pad 130C to the outside. Accordingly, by manufacturing the pad 130C through the three-part mold 100 , it is possible to provide the user with a bra including the pad 130C having excellent durability.

Referring back to FIGS. 8A to 9B , the volume of the plurality of pad patterns may increase from the first pad pattern 130B_1 toward the third pad pattern 130B_3 . That is, the volume of the first pad pattern 130B_1 may be the smallest among the plurality of pad patterns, and the volume of the third pad pattern 130B_3 may be the largest.

As described above, when the bra pad 130C is manufactured through the three-part mold 100 of the present invention, the volume of the plurality of pad patterns is formed to increase from the inside to the outside of the pad 130C, so that the breast correction effect is achieved. may provide an improved pad 130C.

Specifically, as the pad 130C gathers the chest from the outside to the inside, the correction power and the volume-up function may be improved. At this time, when the volume of the third pad pattern 130B_3 is smaller than or equal to the volume of the first pad pattern 130B_1 , the force supporting the breast at the outer portion of the pad 130C may be weak, and the breast correction effect is reduced can be

Accordingly, the volume of the third pad pattern 130B_3 disposed on the outer portion of the pad 130C is formed to be larger than the volume of the first pad pattern 130B_1 through the three-part mold 100 , so that the outside of the pad 130C is formed. The third pad pattern 130B_3 formed in the portion can correct and support the breast so that the chest can be gathered to the central portion of the pad 130C. Accordingly, it is possible to provide the user with the pad 130C having improved chest correction effect and ball-up function.

In addition, the outer shape of the pad member 130A may be formed to have a curved surface along the shape of the concave portion 121 of the lower mold 120 .

Meanwhile, although three pad patterns are illustrated in FIGS. 8A and 8B , the present invention is not limited thereto. The plurality of pad patterns may be four or more.

Then, referring to FIGS. 10A and 10B , the pad 130C is manufactured by cutting the molded pad member 130B (S150), and the outer shell 130CA can be formed along the circumference of the pad 130C ( S160).

Specifically, the pad 130C may be manufactured by cutting the molded pad member 130B having the plurality of pad patterns formed thereon along the shape of the concave portion 121 of the lower mold 120 . Thereafter, along the circumference of the pad 130C, the shell 130CA may be formed.

The outer skin 130CA connects the pair of pads 130C, reduces separation of each layer of the pad 130C, and improves the tactile feel against the body. In this case, since the outer shell 130CA may be made of a material having relatively low heat resistance compared to the material constituting the pad 130C, it may be formed after the pad member 130B is molded.

In a conventional bra, a wire is inserted around the pad in order to maintain the shape of the pad and increase the breast correction effect. However, in the case of a bra in which a wire is inserted, it may cause an uncomfortable fit for the user or skin troubles due to the wire. In addition, when the wire bra is used for a long period of time, the shape of the pad is deformed according to the deformation of the wire, so that it is difficult to obtain the effect of wearing the bra.

Accordingly, according to the present invention, the wire-free wireless bra pad 130C can be manufactured through the three-part mold 100 , thereby providing a more comfortable fit to the user and reducing the user's skin troubles.

Next, referring to FIGS. 11A and 11B , a paddle 130CB is formed on the pad 130C ( S170 ). The paddle 130CB may allow the pad 130C to maintain a convex shape.

Specifically, one or more paddles 130CB may be formed inside the pad 130C. The paddle 130CB may be formed in a semicircular shape to be fixed to the lower curve 130CC of the pad 130C. In this case, the paddle 130CB may be formed to cover a portion of at least two pad patterns among the plurality of pad patterns.

The paddle 130CB includes a first paddle 130CB_1 and a second paddle 130CB_2 . The first paddle 130CB_1 and the second paddle 130CB_2 may partially overlap each other.

For example, the first paddle 130CB_1 may be formed to cover a portion of the first pad pattern 130B_1 and a portion of the second pad pattern 130B_2 among the plurality of pad patterns, and the second paddle 130CB_2 may It may be formed to cover a portion of the second pad pattern 130B_2 and a portion of the third pad pattern 130B_3 among the plurality of pad patterns. Accordingly, a portion of the first paddle 130CB_1 and the second paddle 130CB_2 may be formed to overlap in a region corresponding to the second pad pattern 130B_2 .

Meanwhile, step S170 may be performed when the size of the formed pad 130C is large, that is, when the size of the bra is relatively large.

For example, the wireless bra may have difficulty maintaining the convex shape of the pad 130C when the size of the pad 130C is relatively large, compared to the case where the size of the pad 130C is relatively small. Accordingly, when the size of the pad 130C is large, a paddle 130CB may be formed on the pad 130C to assist in maintaining the shape of the pad 130C.

As one or more paddles 130CB are formed in the pad 130C manufactured according to the method for manufacturing a bra according to some embodiments of the present invention, even if a separate wire is not inserted, the shape of the pad 130C can be easily maintained. have.

Specifically, the paddle 130CB includes a first paddle 130CB_1 and a second paddle 130CB_2 , so that the first paddle 130CB_1 and the second paddle 130CB_2 overlap in some regions, and the first paddle 130CB_1 ) and another portion of the second paddle 130CB_2 may be formed to cover different pad patterns. That is, the first paddle 130CB_1 covers a part of the first pad pattern 130B_1 and a part of the second pad pattern 130B_2 , and the second paddle 130CB_2 covers a part of the third pad pattern 130B_3 and the second pad pattern 130B_3 . 2 It covers a part of the pad pattern 130B_2. Accordingly, the paddle 130CB may be fixed to the pad 130C so that the pad 130C does not spread to both sides.
