Description

Technical Field

[0001] The utility model relates to the field of underwear accessories, in particular to an underwear connecting buckle and an underwear. Background Art

[0002] A bra is one of the essential important clothes for modern people. The most common wearing method of the existing bras is the back-fastening type. Specifically, the back buckle of the back-fastening type bra includes a hook part and a loop part. The hook part and the loop part are respectively sewn on the two back straps of the bra. The wearer realizes the wearing and fixing of the bra by engaging the hook part and the loop part. The hook part is provided with a row of hooks, and the loop part is provided with several rows of loops. The wearer can adjust the wearing tightness of the bra by engaging the hooks of the hook part with different rows of loops of the loop part.

[0003] With the continuous improvement of people's living standards, while people pursue the practicality of bras, they also pay more attention to the wearing comfort of bras. Consumers generally focus on the fabric and breathability of the cup when considering the comfort of bras. However, as a close-fitting garment, the comfort of bras is not only limited to the part in contact with the wearer's chest, but also affects the overall wearing experience of the wearer in many details. Since the back buckle of the bra needs to bear the connection force when the bra is worn and also carry the hooks or loops, the back buckle of the bra needs to have a certain hardness requirement, which is likely to cause discomfort to the wearer. Conventionally, the loops of the loop part are sewn on the front of the loop part. Therefore, corresponding stitches will be generated on the back of the loop part. When wearing, the back of the loop part faces the wearer. The wearer is prone to have a mark on the back due to the extrusion of the stitches, and due to the friction between the skin and the stitches, the wearer is prone to discomfort when wearing, reducing the wearing comfort.

[0004] Therefore, in order to hide the stitches and enhance the skin-friendly effect of the back buckle, the two mainstream solutions on the market are the reverse edge wrapping process and the heat-pressing bonding process. Taking the loop part as an example, the loop part includes a base cloth and two outer layer cloths. The outer layer cloth is a soft and skin-friendly fabric, and the base cloth provides a certain degree of hardness support. The loop is sewn on the front side of the base cloth. When the reverse edge wrapping process is adopted, the two outer layer cloths are stacked on the front side of the base cloth, and three side edges of the base cloth and the outer layer cloth are sewn and sealed, so as to form a pocket between the two outer layer cloths. The pocket is turned outwards from the unsewn edge of the two outer layer cloths, so that the base cloth is accommodated between the two outer layer cloths, and the corresponding stitches are hidden by the outer layer cloth, and the discomfort of the base cloth is relieved by the direct contact between the outer layer cloth and the wearer. However, since the outer layer cloth and the base cloth do not fit well, it is easy to arch after washing, and the durability is poor. When the heat-pressing bonding process is adopted, the two outer layer cloths are arranged on two opposite sides of the base cloth, and a hot melt adhesive layer is arranged between the outer layer cloth and the base cloth, and the hot melt adhesive layer is used to bond the outer layer cloth and the base cloth by the heat-pressing hot melt process. Subsequently, the ultrasonic cutting is used to fix the edges of the fabric. Although the heat-pressing bonding process ensures the fit between the outer layer cloth and the base cloth and also hides the stitches, the fabric will be burned and hardened when subjected to the high temperature of the cutting, resulting in an uncomfortable feeling of a hard object stabbing the body for the wearer.

[0047] Referring to the accompanying drawings of the specification of this utility model Figures 1 to 18 , an undergarment connection buckle 10 and 10A according to an embodiment of this utility model are schematically shown. Among them, corresponding to Figures 1 to 3 , Figures 5 to 11 shown, the undergarment connection buckle 10 carries at least one buckle ring 14. Corresponding to Figure 4 , Figures 12 to 18 shown, the undergarment connection buckle 10A carries at least one buckle hook 15. Among them, the buckle hook 15 of the undergarment connection buckle 10A is adapted to hook onto the buckle ring 14 of the undergarment connection buckle 10. Referring to Figure 19 shown, the undergarment connection buckle 10 and the undergarment connection buckle 10A are arranged on two straps 40 of an undergarment 100. Based on the mutual buckling of the undergarment connection buckle 10 and the undergarment connection buckle 10A, the wearing and / or tightness adjustment of the undergarment 100 is realized.

[0048] Specifically, the underwear connecting buckles 10 and 10A include a base cloth 11, a surface cloth 13, and a perforated cloth 12. On one side of the base cloth 11 of the underwear connecting buckle 10, the buckle 14 is carried. On one side of the base cloth 11 of the underwear connecting buckle 10A, the hook 15 is carried. At least one perforation 121 is formed in the perforated cloth 12 for the buckle 14 or the hook 15 to pass through. The number of the perforations 121 of the underwear connecting buckle 10 corresponds to the number of the buckles 14, and the number of the perforations 121 of the underwear connecting buckle 10A corresponds to the number of the hooks 15. The perforated cloth 12 is arranged on this side of the base cloth 11 in a state where the buckle 14 or the hook 15 passes through the perforation 121. The surface cloth 13 is arranged on the other side of the base cloth 11 to form a structural form in which the perforated cloth 12, the base cloth 11, and the surface cloth 13 are sequentially laminated. The base cloth 11 is adhesively fixed to the surface cloth 13 and the perforated cloth 12 to prevent the separation of each layer and the occurrence of arching. One side edge of the underwear connecting buckles 10 and 10A has an opening 101, which is formed by avoiding the adhesion of the perforated cloth 12 and the base cloth 11 at this side edge. The underwear connecting buckles 10 and 10A are connected to the shoulder strap 40 at the opening 101. After the surface cloth 13, the base cloth 11, and the perforated cloth 12 are adhesively bonded, they are cold-cut and edge-sealed at the other three side edges, thereby avoiding edge hardening and ensuring the durability of the underwear connecting buckles 10 and 10A and the wearing comfort of the wearer.

[0049] Taking the underwear connecting buckle 10 as an example for further detailed illustration, refer to Figure 2, wherein the surface layer fabric 13, the base layer fabric 11, and the perforated fabric 12 are bonded by a glue film 20, and the glue film 20 is provided with a plurality of ventilation holes. During the manufacturing process, the underwear connecting buckle 10 is arranged in a state where the perforated fabric 12, the glue film 20, the base layer fabric 11, the glue film 20, and the surface layer fabric 13 are sequentially laminated and subjected to hot pressing and melting. The number of the glue films 20 is not limited. After multiple glue films 20 are respectively bonded to the perforated fabric 12, the base fabric 11, and the surface layer fabric 13, the perforated fabric 12, the glue film 20, the base layer fabric 11, the glue film 20, and the surface layer fabric 13 are laminated in sequence and then hot pressed and melted as a whole. For example, the glue film 20 is first bonded to two opposite surfaces of the base layer fabric 11, and the glue film 20 is also bonded to the surfaces of the perforated fabric 12 and the surface layer fabric 13 facing the base layer fabric 11. After the perforated fabric 12, the base layer fabric 11, and the surface layer fabric 13 are laminated, they are hot pressed and melted. And based on the ventilation holes on the glue film 20, a bonding layer with ventilation holes is formed between the base layer fabric 11 and the surface layer fabric 13 and between the base layer fabric 11 and the perforated fabric 12 after hot pressing and melting, so as to facilitate the exhaust between the base layer fabric 11 and the surface layer fabric 13 and between the base layer fabric 11 and the perforated fabric 12, and improve the ventilation performance of the underwear connecting buckles 10 and 10A.

[0050] Further, after hot pressing and bonding, cold cutting is performed to obtain the underwear connecting buckles 10 and 10A with the target size. Refer to Figure 3 , wherein the size of the surface layer fabric 13 is larger than the sizes of the perforated fabric 12 and the base fabric 11. Therefore, in the state where the perforated fabric 12, the base layer fabric 11, and the surface layer fabric 13 are laminated, the surface layer fabric 13 has a folded edge 131 that is not covered by the perforated fabric 12 and the base fabric 11.

[0051] Particularly, as shown in Figure 1 , the folded edge 131 is folded towards the perforated fabric 12 on the other three sides of the underwear connecting buckles 10 and 10A, and the folded edge 131 is connected to the perforated fabric 12, thereby sealing the cold-cut edges of the base layer fabric 11 and the perforated fabric 12, so as to prevent the underwear connecting buckles 10 and 10A from opening at the other three sides and improve the durability of the underwear connecting buckles 10 and 10A.

[0052] It is worth mentioning that the buckle 14 is stitched and fixed to the base cloth 11 by a sewing thread, and the hook 15 is stitched and fixed to the base cloth 11 by a sewing thread, so as to ensure the firmness of the buckle 14 and the hook 15 in a stitching manner. Based on the wrapping of the base cloth 11 by the perforated cloth 12 and the surface cloth 13 on both sides of the base cloth 11, the sewing threads on the base cloth 11 are hidden, making the appearance of the underwear connecting buckles 10 and 10A neat, and at the same time avoiding discomfort caused by the wearer's contact with the sewing threads.

[0053] Specifically, the surface cloth 13 and the perforated cloth 12 adopt a blended fabric incorporated with spandex components to enhance the lightness and thinness of the underwear connecting buckles 10 and 10A, as well as the softness of the underwear connecting buckles 10 and 10A in contact with the skin, and can form a cooling sensation in contact with the wearer, improving the wearing comfort of the wearer. The base cloth 11 has a certain strength, for example, the base cloth 11 contains a non-woven fabric layer to maintain the structure of the underwear connecting buckles 10 and 10A.

[0054] Furthermore, referring to Figure 19 , the underwear 100 includes a cup portion 30 and two straps 40 extending from both side portions of the cup portion 30. The straps 40 have two connecting ends 41 adapted to be connected to each other. The underwear connecting buckle 10 is disposed at one of the connecting ends 41, and the underwear connecting buckle 10A is disposed at the other connecting end 41. Based on the buckling of the underwear connecting buckle 10 and the underwear connecting buckle 10A, the connection of the two straps 40 is realized, thereby realizing the wearing of the underwear 100.

[0055] Furthermore, the underwear connecting buckle 10 is connected to the strap 40 in a stitching manner. Specifically, one of the connecting ends 41 is inserted into the opening 101 of the underwear connecting buckle 10, and the underwear connecting buckle 10 and the connecting end 41 are stitched and fixed by a sewing thread. The other connecting end 41 is inserted into the opening 101 of the underwear connecting buckle 10A, and the underwear connecting buckle 10A and the connecting end 41 are stitched and fixed by a sewing thread.

[0056] It can be understood that the specific number of the buckles 14 can be flexibly adjusted according to actual needs, for example, corresponding adjustments are made based on the type of the underwear 100. The buckles 14 can be arranged in a single row, two rows, three rows, etc. The number of the buckles 14 in each row can be one, two, three, four, etc. That is to say, the specific number of the buckles 14 does not constitute a limitation of the present utility model. The specific number of the hooks 15 corresponds to the number of the buckles 14 in each row. For example, when three buckles 14 form a row, the number of the hooks 15 is set to three.
