And press by a second mold 11 having a back side shape to form a three-dimensional mold cup having a predetermined shape.
By heating at 80 ° C. for 10 to 20 minutes, the periphery of the top cloth 1 and the back cloth 2 and the inside of these nonwoven fabrics are partially melted and bonded to each other, released from the molds 10 and 11, and Is cut into a predetermined shape and commercialized as a mold cup.

When commercializing the actual mold cup 15 based on the basic concept, a three-dimensional shape of the product is set, and the top cloth 1, the back cloth 2, the intermediate cloth 3,
It is necessary to set the shapes of 4, 5, 6,... And the arrangement of the intermediate cloth. 2 to 4 show a front view and a sectional view of an actual product, and show an embodiment of a 3/4 cup mold cup. As is apparent from this figure, the lower bust portion 16 which forms a lower portion of the mold cup 15 is formed substantially symmetrically with respect to the center line L _1, in particular its lower edge 17
It is formed in a circular shape around the point O on the center line L _1. Also, the horizontal cross-section as shown in FIG. 4, the cross section of the top edge portion A portion of the cup is formed in a circular substantially symmetrical with respect to the center line L ₂ of the brassiere.

[0011] In contrast, upper bust portion 20 projecting from the lower bust 16, the apex P is the center point O of the lower bust portion 16, the chest centerline L ₂ side, i.e., located on the front side 18 located on the center line L _3, and the center point O
It is located above. Moreover, as is clear from part B sectional view in FIG. 4 shown as a horizontal cross section of the line portion B in FIG. 2, the portion on the center line L ₃ are the most protruding body side side, i.e. at the rear side 21 Is the front side 25
Is smoothly connected to the edge 18 while the back 26
Is connected from the substantially circular curve 30 forming the vertex to the inverted convex backside curve, whereby the lower bust 1
6 has a thick portion 32 formed between the front side 25 and the back side 26.

Further, as it is clear from FIG. 3 is a sectional view on the center line L ₃ of Figure 2, lower bust portion 16 from the top P
, The front side 25 is connected by a smooth identical curve, while the back side 26 is connected to a curve 35 from the top A and a curve 36 of the lower bust part, similarly to the shape of the lower bust part in FIG. Are inverted and connected in a convex shape, whereby the lower bust portion 16 has a thick portion 38 formed between the front side 25 and the back side 26.

In order to obtain the three-dimensional shape of the mold cup as described above, as shown in FIGS. 2 and 5 which are front views after molding, a portion from the middle portion of the upper bust portion 20 to the lower bust portion 16 is formed. In between, as in the basic concept shown in FIG. 1, a plurality of intermediate cloths 3, 4, 5, 6,... Are laminated to form thick portions 32, 38. That is, although it differs depending on the thickness of the non-woven fabric used and the thickness of the maximum thickness portion, in FIG.
Are laminated between the front cloth 1 and the back cloth 2. And, as is clear from FIG. 5, the stacking position is centered on the top P,
It is arranged so as to have a maximum thickness portion substantially concentrically downward. Due to the three-dimensional shape of such a mold cup, if it is used inside a bra, etc., even a person with a relatively small chest can obtain a bust shape with a sense of volume, and the top of the upper bust portion is Combined with the thick portion which is displaced upward and forward from the center of the lower bust portion and located below, the breast is moved upward and forward 18 to form a curved bust with excellent fashionability.

At the time of molding the mold cup having such a shape, as shown in FIG. 5, after molding, the intermediate cloths 3, 4, 5, 6 for forming the thick portion in the mold cup are arranged in advance. Front cloth 1 and back cloth 2 cut into a predetermined shape
Laminate between. These laminated nonwoven fabrics are placed on the lower mold 45 as shown in FIG. 6, and press the upper mold 46 from above. The inner surface of the lower die 45 has a shape that matches the shape of the front side of the molded cup after molding, and the inner surface of the upper die 46 has a shape that matches the shape of the back side of the mold cup. At this time, in order to surely form the top P, particularly in the upper die 46, a relatively sharp bend is formed at the top,
It is preferred to ensure that the top is formed. When the laminated body 7 of the front cloth 1, the back cloth 2 and the nonwoven fabric is arranged between the lower mold 45 and the upper mold 46 and the upper mold 46 is strongly pressed against the lower mold 45 as shown in FIG. The non-woven fabric laminated on is formed into a predetermined shape while being compressed, and then receives heat of about 180 ° C. from a mold, and the intermediate fabric inside the peripheral fabric, including the peripheral lamination portion of the top cloth 1 and the back cloth 2, is also formed. Partially melted and integrated. Thereafter, the mold is separated, the product is taken out, and the molding is completed.

A product formed in the above-described manner has a left-right symmetrical shape, and is fixed in left and right cup portions 51, 52 of a brassiere 50 formed as shown in FIG. At that time, the left and right cup portions 5 of the brassiere 50
The vertices Q of 1,52 are formed as described above and are formed so as to coincide with the vertices P of the mold cup. As a result, the cup portions 51 and 52 and the mold cup fixed inside have close contact because they substantially match in shape, and the fabric of the brassiere 50 prevents the mold cup from deforming. The mold cup can be arbitrarily changed according to the appearance, pattern, design, etc. of the bra.

The nonwoven fabric used in the present invention may be composed entirely of a low-melting thermoplastic fiber. For example, the main fiber made of a high-melting thermoplastic fiber such as polypropylene or polyester may be replaced with a low-melting thermoplastic fiber such as polyethylene. A composite fiber obtained by mixing with a melting point thermoplastic fiber may be used.

The present invention can be applied to a full-cup and half-cup brassiere. Further, the present invention is not limited to brassieres, and can be applied to mold cups such as swimwear, body suits, dresses with cups, and the like.

[0018]

The present invention is configured as described above.
By using the mold cup according to the present invention, it is possible to prevent and support the user from moving the breast downward and to the side of the chest, increase the volume, and bring the breast upward and toward the center of the chest, thereby providing excellent fashionability. A curved shape can be obtained. In addition, in order to obtain such a shape, the nonwoven fabric is laminated and heat-melt-integrated and molded, so that it does not change over time with a yellow color as in the case of molding a urethane material, and has a smooth feel and one sheet. No deformation such as returning to the original shape due to washing occurs as in the case where the nonwoven fabric is press-formed, and stable properties and shapes can be maintained for a long time.

Further, since the top of the upper bust portion is displaced upward and forward from the center of the lower bust portion, the shape of the mold cup is such that the top of the upper bust portion is upward and forward in the entire mold cup. The maximum thickness part is formed concentrically downward from the upper bust top as a center, as described above, and the volume of the breast is increased, and a shape excellent in fashion is obtained. be able to.

Furthermore, since the center of the bust cup portion of the outer cloth such as a bra is formed so as to coincide with the top of the upper bust section of the mold cup fixed therein, the outer cloth such as the bra and the mold fixed therein may be formed. The shape of both cups can be made to match, and the shape of the mold cup configured as described above can be securely held by a surface cloth such as a brassiere to prevent deformation.
