Manufacturing method of molded cup for bra that provides comfortable wearing feeling {Manufacturing method of molded cup for bra that provides comfortable wearing feeling}

The present invention relates to a mold cup for a brassiere and a method for manufacturing the same, which is a mold cup for a brassiere used to form a left cup or a right cup of a brassiere, so that the cup shape of the brassiere can be maintained without using a wire for maintaining the shape of a metal material. It relates to a mold cup for a brassiere configured to provide a comfortable fit to the wearer's skin while providing a sense of volume of the brassiere and a manufacturing method thereof.

BACKGROUND ART A bra is a female undergarment that covers a breast, serves to support and protect the breast, and corrects the shape of the breast, and is generally made of a flexible fiber material.

11 is a perspective view showing an example of a conventional general brassiere.

As shown in FIG. 11, the general structure of the brassiere 104 is two cups 101 on the left and right sides in which a space capable of accommodating a woman's breast is formed, and the left and right sides of the cup 101 are connected to the wearer's back. It is a structure composed of a connection strap 102 that can be fastened to each other, and a shoulder strap 103 fixed to the top of the connection strap 102, respectively, in a state where it is hung on the wearer's shoulder at the top of the cup 101.

12A is a perspective view showing an example of a conventional mold cup, FIG. 12B is a cross-sectional view of FIG. 12A cut vertically, and FIG. 12C is a cross-sectional view of a brassiere equipped with a mold cup cut along the center of FIG. 12A.

In order to provide a certain shape or volume to the left cup or right cup of the bra as described above, the brassiere generally has a body portion 10 in a shape of a rod that is curved toward the front side and gently protrudes from the inside of the cup of the bra. The mold cup 1 for use is installed inside.

Such a mold cup 1 for a brassiere is generally provided with a body portion 10 having the same shape as described above, formed to a predetermined width along the lower rim of the body portion 10, and a wire for maintaining the shape. A wire loop 50 for inserting is integrally provided with an edge portion 20 for attachment.

The wire loop 50 is a woven material in the form of a band extended in a hollow shape, and is attached to the rim 20 of the mold cup 1 along the longitudinal direction in the process of manufacturing a finished brassiere by a bar, and there is a wire for maintaining the shape therein. After 40 is inserted, both ends are finished with the bar. Reference numeral 30 in FIG. 12C denotes an outer shell for a brassiere.

The body portion 10 and the edge portion 20 include, for example, an elastic material layer made of a material such as sponge, nonwoven fabric, woven pad, or silicone, and an outer skin layer adhered to the front and/or rear surface of the elastic material layer. It is integrally formed by pressing and molding the prepared base material, including a mold of a predetermined shape.

However, since the rim portion 20 of the conventional mold cup 1 for a brassiere is formed in a simple flat shape, a wire loop 50 is attached and a wire 40 is inserted thereto to manufacture a finished brassiere product. After that, some problems occurred when worn by the user.

That is, since the edge portion 20 is pressurized and molded with a mold, for example, the base material to which the elastic material layer and the outer skin layer are integrally bonded, it has physical properties that are compressed harder than the base material by pressing. When wearing a brassiere by fastening, the rim 20 of the mold cup, the wire loop 50, the wire 40, and the wear surface of the user (chest side skin) are mutually pressurized, so the wear surface of the user wearing the bra Problems such as the wire 40 for shape retention causing discomfort or generating wire pressing marks have occurred.

Prior art has been proposed to address the above problem. For example, Korean Patent Publication No. 10-2014-0079494 (published on June 26, 2014) discloses a support member included adjacent to the lower edge of the bra cup and embedded in the padding of the bra cup and using the same to manufacture a bra cup. I have suggested how to do it.

However, in the bra cup manufacturing method of the prior art, a first part made of polyurethane foam and having a concave side is prefabricated, a second part made of polyurethane foam and has a convex side is prefabricated, and then Because it is a method of combining by placing a support member therebetween, there was a limitation that several mold operations were required to manufacture a semi-finished cup forming a concave or convex side.

In addition, the bra cup manufacturing method of the prior art has a limitation in that the burden of manufacturing a mold for manufacturing support members of various sizes and shapes is large because the support member is manufactured by injection molding.

The present invention relates to a mold cup for a brassiere and a method for manufacturing the same, which is a mold cup for a brassiere used to form a left cup or a right cup of a brassiere, so that the cup shape of the brassiere can be maintained without using a wire for maintaining the shape of a metal material.

In step S1, the first elastic material 210 to which the first shell 212 is attached to the front surface of the core material 202 made of an elastic material is charged into the fixed mold FM, and the movable mold MM is pressed to perform semi-processing. The mold cup 1' is molded. (FIGS. 1 to 3)

The core material 202 may be made of at least one of a sponge, a non-woven fabric, a woven pad, and silicon. The core material 202 may be prepared by cutting, for example, a flat raw material having a thickness of 5 to 10 mm into an appropriate size.

The first elastic material 210 is prepared by bonding the first sheath 212, which is a fiber material, to the raw material of the flat core 202. Preferably, the first elastic material 210 does not have to undergo a pre-pressing process before step S1.

The semi-finished mold cup 1' has a main body portion 1010' curved and protruding toward the front side and an edge portion extending with a predetermined width along the lower edge of the body portion 1010' ( 1020').

The rim portion 1020' extends along the length of the rim and has a flat shape curved round along the round outline of the cup as illustrated in FIG. 10 .

Preferably, in step S1, at least one of the fixed mold FM and the movable mold MM is preheated before pressing the movable mold MM. For example, the preheating may be performed by a rod-shaped electric heater (not shown) inserted into the mold, or by preheating the mold surface with a separately provided plate-shaped electric heater (not shown). The preheating temperature may be set in the range of 180 to 210 ° C in consideration of the thermal deformation characteristics of the material.

In step S2, the movable mold (MM) is separated from each other, and the shape-maintaining material 1040 is deposited on the inner upper portion of the edge portion 1020' of the semi-finished mold cup 1' located in the fixed mold FM. (FIGS. 4 to 5)

The shape-retaining material 1040 may be a synthetic resin material that is harder than the core material 202 and can be deformed by heating and pressing. As an example, a polypropylene-based resin may be used as the synthetic resin material, and it is not necessarily limited thereto as long as it has a hard property similar to that of the polypropylene-based resin and can be deformed by heating and pressurization.

The shape-retaining material 1040 is a material that is harder than the core material 202 and has a flat cross-sectional shape and an extended planar shape to be inserted along the longitudinal direction of the concave portion 1020b'. 10 illustrates a shape-retaining material 1040 extending in a planar shape having a width w and a thickness t.

Preferably, the shape-maintaining material 1040 is a flat synthetic resin raw material (eg, a rectangular raw material having a thickness of 2 to 3 mm) under preset size and shape conditions (eg, a width of 4 to 6 mm and a length of 150 to 280 mm). It is obtained by press cutting according to a curved planar shape of the order of mm). Preferably, a plurality of shape-retaining materials 1040 may be obtained at once by preparing a plurality of flat synthetic resin raw materials in an overlapping state and cutting them with a press.

According to the present embodiment, since a shape-retaining material is manufactured by a press method using a relatively low-cost flat-type synthetic resin raw material sold as a commercial product, a shape-retaining material having various sizes and shapes can be easily manufactured compared to the injection molding method. It has the advantage that it can be manufactured in a low-cost way.

In addition, according to this embodiment, since the shape-retaining material 1040 has a flat cross-sectional shape, the shape-retaining material maintains a state in close contact with the inner upper part of the edge portion 1020' during the manufacturing process using a mold, so that it shakes or flows. It has the advantage of being able to hold the position firmly without doing it.

In step S3, the adhesive (G) is applied to the front surface of the second elastic material 220 to which the second shell 222 is attached to the rear surface of the core material 202 made of an elastic material, and the semi-finished mold cup 1' is formed. It is charged to the fixed mold (FM) in the form of overlapping the rear surface. (FIG. 6)

The second elastic material 220 is prepared by bonding the second shell 222 of a fiber material to the raw material of the flat core 202 . Preferably, the second elastic material 220 does not have to undergo a pre-pressing process before step S3.

Preferably, in this embodiment, the sum of the thickness t1 of the first elastic material 210 and the thickness t2 of the second elastic material 220 is greater than the maximum thickness tm of the mold cup 1. arrange to have

According to this embodiment, since the mold cup is molded by additionally charging the shape-retaining material and the second elastic material into the same mold without separating the semi-finished mold cup from the mold after forming the semi-finished mold cup, intermediate steps are taken to manufacture the mold cup. There is no need to separate the molding from the mold or set the position again in the mold, and it has the advantage of simplifying the mold process.

In step S4, the movable mold MM is pressed to obtain the mold cup 1 integrally molded with the first elastic material 210, the shape-retaining material 1040, and the second elastic material 220. (FIG. 7)

Preferably, at step S4, at least one of the fixed mold FM and the movable mold MM is preheated before pressing the movable mold MM.

Through the above manufacturing process, the mold cup 1 in which the first elastic material 210, the shape-retaining material 1040, and the second elastic material 220 are integrally molded is obtained. The structure of this mold cup 1 will be described.

8 is a schematic cross-sectional view of a mold cup for a brassiere according to an embodiment of the present invention, and FIG. 9 is a perspective view of a mold cup for a brassiere according to an embodiment of the present invention.
