[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0023] See also Figures 1 to 4 As shown, a glue-pointed seamless bra of the utility model comprises an underwear body 1, a cup 2 arranged on the underwear body 1 for covering the chest of the user; and also comprises a plurality of adhesives 3 arranged on the underwear body 1 or / and the cup 2, the cup 2 comprises a flexible gasket 21, a cup cloth 22 arranged on the flexible gasket 21, and the flexible gasket 21 and the cup cloth 22 are connected via the adhesive 3. In this embodiment, the underwear body 1 is a sports underwear, and the width of the bottom of the body, i.e., the bottom circumference 25, is larger, in order to provide better support for the user, the cup 2 is configured to adapt to the chest shape of the user, the flexible gasket 21 is formed by laminating a sponge layer, a breathable silicone layer, and a sponge layer, and is fixed in the cup cloth 22 by two circles of adhesive 3.

[0024] Specifically, the cup cloth 22 includes an inner lining 221 that fits the user's skin and an outer cover 222 that is arranged back to back with the inner lining 221. Two flexible gaskets 21 are arranged in the inner lining 221 and the outer cover 222. The flexible gasket 21 is roughly bowl-shaped. The two bowl-shaped flexible gaskets 21 separate the inner lining 221 and the outer cover 222 to form a neckline 23, a bend 24, a bottom circumference 25 and side wings 26. The bend 24 is located between the two flexible gaskets 21 and is connected to the neckline 23. The bend 24 and the neckline 23 form a "Y"-shaped structure. Multiple adhesives 3 are respectively arranged on the neckline 23, the bend 24, the bottom circumference 25 and the side wings 26. The inner lining 221 and the outer cover 222 are hot-pressed and bonded by multiple adhesives 3 to form the cup cloth 22.

[0025] In this embodiment, the outer cover 222 and the inner lining 221 are made of the same material and are integrally constructed, and are folded and folded at the neckline 23, and are heat-pressed and bonded at the bottom circumference 25 by an adhesive 3. In actual use, the outer cover 222 and the inner lining 221 of different materials can be selected, and then the two are heat-pressed and bonded by an adhesive 3 to form the cup cloth 22.

[0026] Specifically, the adhesive 3 is distributed in an array at the neckline 23, the bend 24, the bottom circumference 25 and the side wings 26 by dot-dispensing and combining their shapes. The adhesive 3 treated in this way can be more evenly distributed at the key parts of the bra, improving the uniformity and stability of bonding. The dot-dispensing and hot-pressing bonding after distribution along the contour of the bra can ensure that the glue points or glue lines formed by the adhesive 3 on the surface of the bra match the contour lines of the bra, making the bonding parts smoother and neater, and improving the appearance of the underwear.

[0027] Specifically, glue dispensing lines 4 used in conjunction with adhesive 3 are provided at the bend 24, the neckline 23, and the bottom circumference 25. Two glue dispensing lines 4 are provided at each location, and the spacing between two adjacent glue dispensing lines 4 is 1.5-2.5 mm. The addition of glue dispensing lines 4 can arrange the position coordinates in advance for subsequent glue dispensing operations, thereby improving the accuracy of the glue dispensing position. For example, during actual production, the position and shape of the bra are detected by a visual positioning system, and glue dispensing lines 4 are preset at the positions where glue dispensing is required. Afterwards, the automated glue dispensing machine performs point-like or line-like glue dispensing according to the set glue dispensing lines 4, ensuring that the adhesive 3 is accurately applied at the required position.

[0028] Specifically, an elastic band 5 is provided at the neckline 23, and the elastic band 5 includes a first yarn and a second yarn, the first yarn is modal fiber, the second yarn is lycra spandex fiber, and the first yarn and the second yarn are interwoven with each other through weft knitting to form the elastic band 5; the outer cover 222 is folded toward the inner lining 221 and is hot-pressed and bonded to the inner lining 221 through the dot-shaped adhesive so as to limit the elastic band 5 at the bottom circumference 25.

[0029] Modal fiber is soft, smooth and breathable, while Lycra spandex fiber has excellent elasticity and can provide good stretchability and resilience. The two are combined and interwoven with each other through weft knitting to form an elastic band 5, and the elastic band 5 is fixed at the neckline by point gluing. This allows the underwear body 1 to have both comfort, durability, strong adhesion and seamless characteristics.

[0030] Specifically, the underwear body 1 also includes a strap 11 connected to the cup 2, and the strap 11 and the outer cover 222 are integrally constructed. The integral structure of the strap 11 and the outer cover 222 avoids the phenomenon of fracture at the connection caused by the split setting, so that the user can wear it more smoothly without being visible on the outer clothes, and it is more beautiful and concealed.

[0031] Specifically, the underwear body 1 further includes a shoulder strap 12 arranged in cooperation with the back strap 11, the shoulder strap 12 and the outer cover 222 are of an integral structure, and the free end of the shoulder strap 12 and the back strap 11 are heat-pressed and bonded via an adhesive 3. The integral structure of the shoulder strap 12 and the outer cover 222 forms a stronger connection, reduces the possibility of loosening or falling off, does not require additional seams or fixings, reduces protrusions on the surface of the underwear, is more concealed and beautiful, and improves wearing comfort.

[0032] Specifically, the flexible pad 21 is provided with a plurality of ventilation holes, the aperture of the ventilation holes is 1-2 mm, and the spacing between adjacent ventilation holes is 2-8 mm. In actual use, the size of the ventilation holes can be adjusted according to bras of different sizes.

[0033] Specifically, the adhesive 3 includes polyurethane, zinc oxide filler and a temperature-sensitive layer, and the temperature-sensitive layer is used to adjust the flexibility of the adhesive 3 in accordance with the user's body temperature. The addition of zinc oxide can enhance the mechanical properties and durability of the adhesive 3, while reducing the viscosity of the adhesive 3, which helps to achieve more uniform dispensing and coating; in actual production, bio-based polylactic acid can be added to the adhesive 3, and these ingredients can improve the biodegradability of the adhesive 3.

[0034] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
