[0058] As shown in FIGS. 1 and 4, in these embodiments, a molded cup includes a first fabric layer 510, a cup core 300, and a second fabric layer 520. The first fabric layer 510 and the second fabric layer 520 are respectively provided on an outer surface and an inner surface of the cup core 300. The cup core 300 is filled with fluff 320. The first fabric layer 510 and the second fabric layer 520 are respectively bonded to the outer surface and the inner surface of the cup core 300 by adhesive.

[0059] As shown in FIG. 2, according to an embodiment, the cup core 300 is manufactured by molding of a liquid foam material 310, and the fluff 320 is filled between the liquid foam material 310. The cup core 300 includes an upper layer 301, an intermediate layer, and a lower layer 302. The fluff 320 is filled between the upper layer 301 and the lower layer 302, and the upper layer 301 and the lower layer 302 of the cup core 300 are manufactured by molding of the foam material 310. The fluff 320 is in non-contacting connection with the first fabric layer 510 and the second fabric layer 520. The cup core 300 is manufactured by molding of the liquid foam material 310, and the fluff 320 is filled between the liquid foam material 310.

[0060] The fluff 320 is filled in a central region between the upper layer 301 and the lower layer 302, and peripheral regions of the upper layer 301 and the lower layer 302 are attached to each other.

[0061] As shown in FIGS. 2 and 3, the manufacturing method of the molded cup according to the present embodiment includes the following steps:

[0062] S1. selecting a foam mold including two parts of a male die 100 and a female die 200, in which a model of the foam mold corresponds to the shape of the cup core 300;

[0063] S2. placing the first fabric layer 510 into the female die 200;

[0064] S3. injecting an appropriate amount of foam material 310 over the first fabric layer 510, then placing a desired amount of fluff 320 over the foam material 310, and then continuing to inject an appropriate amount of liquid foam material 310 over the fluff 320;

[0065] S4. placing the second fabric layer 520 over the foam material 310 in step S3; and

[0066] S5. folding the male die 100 and the female die 200, taking out by low-temperature molding to obtain a semi-manufactured cup 530, and tailoring the semi-manufactured cup 530 to obtain a cup 500.

[0067] The cup core 300 in the present embodiment is filled with fluff 320 having features of breathability, small density, and strong stretching force, so that the cup 500 can be increased in volume.

[0068] The fluff 320 may be cotton, down, or silk and other materials; the first fabric layer 510 and the second fabric layer 520 may be cotton or cloth, or the like.

[0069] The foam material 310 is provided to facilitate filling fluff 320 and avoid direct contact of the fluff 320 with the first fabric layer 510 and the second fabric layer 520. In addition, the foam material 310 has good support and shaping effects, which can avoid deformation of the cups 500, and can also provide good support and protection for the breasts.

[0070] The following is a test on cup wearing effects of the present embodiment and a comparative example.

[0071] In this test, a cup in the comparative example differs from the cup 500 in the present embodiment in that no fluff 320 is added in the comparative example.

[0072] Test results are shown in Table 1 below:

TABLE-US-00001 TABLE 1 Embodiment Comparative Example Cup thickness Cup thickness Cup thickness Cup thickness (mm) before (mm) after (mm) before (mm) after fitting fitting fitting fitting Wearer 1 15 12 15 14 (bust: 34B) Wearer 2 15 8 15 12 (bust: 34C)

[0073] As can be seen from Table 1, the cup 500 in the present embodiment is mainly adapted to breast sizes by changing thickness of the cup 500 itself. While the cup in the comparative example presses the breasts in an opposite direction due to insufficient flexibility of the cup.

[0074] Therefore, according to the present embodiment, the adaptability of the cups 500 is improved after increasing volumes of the cups 500 by filling fluff 320. For example, when a wearer has a large bust, the inside of the cup core 300 is appropriately expanded outward from the breast, the fluff 320 is subjected to pressure and adapts to the bust of the wearer by decreased thickness, and achieves that cups 500 in the same size can meet requirements of wearers having different cup sizes, especially wearers having left and right breasts different in shape and size, or wearers having different bust sizes.

[0075] As shown in FIG. 5, in this embodiment, the cup core 300 of the molded cup is provided with a plurality of holes 400, and the plurality of holes 400 enclose a diamond shape. The holes 400 in the cup core 300 are provided throughout the entire cup core 300. The angle of the upper angle and the lower angle of the diamond enclosed by the plurality of holes 400 is 45 degrees, and the angle of the left angle and the right angle of the diamond is 135 degrees. Regions provided with the holes 400 in the cup core 300 extend to the peripheral regions of the upper layer 301 and the lower layer 302, and the holes 400 located in the peripheral regions of the upper layer 301 and the lower layer 302 are through-connecting.

[0076] In the present embodiment, the configuration of the plurality of holes 400 provided in the cup core 300 can enhance stretchability of the cup core 300 and intensify expandability of the cup core 300, so that the cup core fits the breasts better, and can avoid displacement of the cups 500 when the wearer is in motion. The breathability of the cup core 300 can also be enhanced with such configuration, as the holes 400 facilitate air flow from the cup core 300, which can achieve rapid air flow, reduced flow resistance, and increased breathable effects of the cup core 300, thereby enabling the breasts to smoothly breathe.

[0077] As shown in FIG. 10, two adjacent holes 400 in a transverse direction and two adjacent holes 400 in a longitudinal direction enclose a diamond shape among a plurality of holes 400.

[0078] An angle r of the upper angle and the lower angle of the enclosed diamond is 45 degrees, and an angle R of the left angle and the right angle of the diamond is 135 degrees.

[0079] As shown in FIGS. 6 to 9, in these embodiments, the manufacturing method of the molded cup includes the following steps:

[0080] S1. selecting a foam mold including two parts of a male die 100 and a female die 200, in which a model of the foam mold corresponds to the shape of the cup core 300;

[0081] S2. injecting the liquid foam material 310 into a corresponding shape of the female die 200 through a spraying head, then placing a desired amount of fluff 320 on the foam material 310, and continuing to inject an appropriate amount of liquid foam material 310 over the fluff 320;

[0082] S3. folding the male die 100 and the female die 200 and taking out a cup core 300 by low-temperature molding, in which the injected foam material 310 is shaped into the cup core 300 with a desired shape in a defined space of the foam mold;

[0083] S4. punching holes 400 on the cup core 300, the holes 400 passing through the cup core 300, the holes 400 forming a diamond shape on the surface of cup core 300, the angle of the upper angle and the lower angle of the diamond enclosed by the plurality of holes 400 is 45 degrees, and the angle of the left angle and the right angle of the diamond is 135 degrees;

[0084] S5. placing the first fabric layer 510 into the female die 200, then placing the cup core 300 obtained in step S4 on the first fabric layer 510, and then placing the second fabric layer 520 on the cup core 300; and

[0085] S6. folding the female die 200 and the male die 100 in step S5, obtaining a semi-manufactured cup 530 by molding, and tailoring the semi-manufactured cup 530 to obtain a cup 500.

[0086] In step S5, the cup core 300 is bonded to the first fabric layer 510 and the second fabric layer 520 respectively by an adhesive 330, the molding process can be under low temperature conditions that provide better protection for fabrics and protect color and surface of the cup 500. It should be noted that a manner to fit the cup core 300 with the first fabric layer 510 and the second fabric layer 520 is not limited to bonding using adhesive 330, but may also be in the form of spray coating, an adhesive film, and the like.
