Description

Technical Field

[0001] This utility model belongs to the field of underwear technology, specifically relating to a bra with a highly elastic and breathable patch structure. Background Technology

[0002] As everyday underwear, the comfort and functionality of a bra are of paramount importance. Traditional bras typically consist of two cups, the upper edges of which together form the neckline. Currently, the neckline is usually finished with a sewn edge or adhesive tape to secure the fabric.

[0003] However, while the aforementioned fully sealed edge structure can cover the edges and provide some support, it still has the following drawbacks in practical applications:

[0004] On the one hand, the nature of this fully sealed structure makes it difficult to provide effective elastic stretching during human movement; specifically, due to the lack of dynamic elasticity, the bra is prone to causing pressure and marks when worn; in particular, the pressure on the front neckline can lead to chest discomfort.

[0005] On the other hand, to maintain a fixed cup shape, traditional bras typically use multi-layered composite materials and a thick, one-piece adhesive layer for reinforcement at the front neckline. This process further sacrifices the breathability of the material, making it difficult for heat and moisture to dissipate in this area, leading to a stuffy feeling after prolonged wear and affecting the wearing experience. For example, in the prior art, Chinese patent CN214483292U discloses a soft-support jelly strip sports back bra. This back bra has a gathering area above the concave position in the middle of the cup (i.e., at the front neckline), and the gathering area contains a gathering elastic adhesive strip. Although the one-piece gathering elastic adhesive strip can enhance the adhesion, the problem of poor breathability still exists after the front neckline is glued.

[0006] Therefore, there is an urgent need for a bra with a highly elastic and breathable patch structure. Summary of the Invention

[0007] To address the problems in related technologies, this utility model proposes a bra with a highly elastic and breathable patch structure to overcome the aforementioned technical problems in existing related technologies. By providing a first elastic patch structure at the front neckline, this utility model can significantly improve the elasticity and breathability of the front neckline of the bra while ensuring effective support and shaping, thereby meeting the growing demand of users for a comfortable and dry wearing experience.

[0008] The technical solution of this utility model is implemented as follows: A bra with a highly elastic and breathable patch structure includes a front band, wherein the height direction of the front band covering the breast is defined as longitudinal, and the length direction of the front band covering the breast is defined as transverse; the front band includes two cups for covering the breasts, a front neckline is provided above the two cups, and the outer side of each cup extends towards the arm and forms a curved portion for covering the accessory breast:

[0009] The front part includes an outer fabric and an inner fabric that is fitted and connected to the outer fabric;

[0010] The front collar is provided with a first elastic patch structure, and each of the bending portions is provided with a second elastic patch structure; the first elastic patch structure includes multiple adhesive strip portions and multiple breathable portions;

[0011] Each of the adhesive strips is attached between the outer fabric and the lining fabric, and extends longitudinally upward from the upper side of the cup to the edge of the bra; the multiple adhesive strips are arranged at intervals in the horizontal direction; the breathable portion is formed between two adjacent adhesive strips; the adhesive strips and the breathable portion are arranged alternately in the horizontal direction; the horizontal tensile elasticity of the front neckline and the gusseted portion is greater than the horizontal tensile elasticity of the lower part of the front band.

[0012] Furthermore, the adhesive strip is an elastic colloid; both the outer fabric and the lining fabric are made of elastic and breathable fabric cut in one piece.

[0013] Furthermore, this invention involves applying liquid elastic colloid to the corresponding positions of the outer or inner fabric using a glue applicator, and then curing it to form the adhesive strip.

[0014] Furthermore, each of the second elastic patch structures also has multiple adhesive strip portions and multiple breathable portions.

[0015] Furthermore, a breathable portion without adhesive bonding is formed between two adjacent adhesive strip portions.

[0016] Furthermore, the adhesive strip is fixed between the outer fabric and the inner fabric by heat pressing or adhesive bonding.

[0017] Furthermore, the width of the adhesive strip portion ranges from 3 to 5 mm.

[0018] Furthermore, each of the described adhesive strips is a continuous straight line, wavy line, or serrated line.

[0019] Furthermore, the width of the ventilated portion is in the range of 2-3 mm.

[0020] Furthermore, the front part includes a first side panel and a second side panel symmetrically arranged on the left and right, and each of the side panels and the lower part is provided with an adhesive edge, which is sandwiched between the outer fabric and the inner fabric;

[0021] The rubber edge extends from the upper end to the lower end of the first side panel, then extends along the lower underband to the lower end of the second side panel, and finally extends to the upper end of the second side panel, forming a U-shaped structure.

[0022] Further, a back portion for fitting the back is further included, and the left and right sides of the back portion are correspondingly integrally connected with the two side panels of the front portion respectively.

[0023] Further, two shoulder straps are further included; one end of the shoulder strap is detachably connected with the front portion, and the other end of the shoulder strap extends to be detachably connected with the back portion.

[0024] Further, the left and right ends of the front neck portion are respectively connected with the underarm portions on the left and right sides, and sharp points are formed at the joints; each of the sharp points extends and narrows in a direction away from the cup portion, and the sharp points are used for connecting the shoulder straps;

[0025] A plurality of rubber strip portions of the front neck portion and the underarm portions on both sides are arranged at intervals in sequence to form a continuous structure.

[0026] Beneficial effects of the present utility model:

[0027] (1) As a key area covering the upper part of the chest, the front neck portion needs to adapt to different breast shapes and movement ranges of the human body; the first elastic patch structure can stretch with the natural fluctuation of the chest, avoid the sense of oppression caused by movement or breathing, maintain air permeability, and prevent stuffiness.

[0028] (2) The design that the plurality of rubber strip portions are arranged at intervals in the transverse direction, and the rubber strip portions and the breathable portions are arranged alternately in the transverse direction, can not only maintain the necessary bonding area between the outer fabric and the inner fabric, but also avoid the problem of poor air permeability caused by full-piece adhesive bonding.

[0029] (3) The front neck portion has greater transverse tensile elasticity, which is beneficial for the transverse elasticity to expand the capacity of the cup portion, making it suitable for women during lactation, menstruation and women with large breasts. Brief Description of the Drawings

[0049] Example 1

[0050] like Figure 1-3 As shown, this embodiment provides a bra with a highly elastic and breathable patch structure, including a front band 1. The height direction of the front band 1 covering the breast is defined as longitudinal, and the length direction of the front band 1 covering the breast is defined as transverse. The front band 1 includes two cups 13 for covering the breasts, and a front neckline 14 is provided above the two cups 13. The outer side of each cup 13 extends towards the arm and forms a concave portion 15 for covering the accessory breast tissue.

[0051] The front part 1 includes a front fabric 11 and a back fabric 12 that is fitted and connected to the front fabric 11.

[0052] The front collar 14 is provided with a first elastic patch structure 3, and each of the bending portions 15 is provided with a second elastic patch structure 4; the first elastic patch structure 3 includes multiple adhesive strip portions 5 and multiple breathable portions 6.

[0053] More specifically, each of the second elastic patch structures 4 also has multiple adhesive strip portions 5 and multiple breathable portions 6;

[0054] Each of the adhesive strips 5 is attached between the outer fabric 11 and the lining fabric 12, and extends longitudinally upward from the upper side of the cup portion 13 to the edge of the bra; the plurality of adhesive strips 5 are arranged at intervals in the transverse direction; the breathable portion 6 is formed between two adjacent adhesive strips 5; as shown Figure 4-5 and Figure 7As shown, the adhesive strip 5 and the breathable part 6 are arranged alternately in the horizontal direction, so that the front collar 14 and the bending part 15 have elasticity in the horizontal direction that far exceeds that of the traditional structure.

[0055] More specifically, a breathable portion without adhesive bonding is formed between two adjacent adhesive strip portions.

[0056] Specifically, the lateral tensile elasticity of the front collar portion 14 and the bending portion 15 is greater than that of the lower portion 18 of the front circumference portion 1.

[0057] When the user takes a deep breath or moves their arms back and forth, the first elastic patch structure 3 of the front collar 14 stretches accordingly, the adhesive strip 5 undergoes elastic deformation, and the area of ​​the breathable part 6 expands, working together to provide a comfortable and pressure-free wrap; at the same time, the second elastic patch structure 4 of the gusseted part 15 can fit closely to the armpit, elastically gather the side breasts, and adapt to different shoulder widths and arm circumferences to avoid creating marks; the numerous breathable parts 6 ensure air circulation and improve breathability.

[0058] First, the front neckline 14, as a key area covering the upper chest, needs to adapt to different chest shapes (such as disc chest, hemispherical chest) and range of motion; the first elastic patch structure 3 can stretch naturally with the rise and fall of the chest to avoid pressure caused by exercise or breathing, maintain breathability, and prevent stuffiness.

[0059] Secondly, the second elastic patch structure 4 of the clamping part 15 can adapt to different arm circumferences and shoulder widths, avoiding underarm friction or marks caused by size mismatch. This embodiment not only ensures the wrapping of accessory breasts, but also avoids excessive tightness.

[0060] Moreover, the design of the adhesive strip 5 can maintain the necessary bonding area between the outer fabric 11 and the inner fabric 12, and avoid the problem of poor breathability caused by full-piece adhesive bonding.

[0061] In addition, the front neckline 14 and the gusseted portion 15 have greater lateral stretching elasticity, which is beneficial for expanding the capacity of the cup portion 13 laterally, making it suitable for breastfeeding women, menstruating women, and women with large breasts.

[0062] Specifically, the adhesive strip 5 is an elastic colloid; the outer fabric 11 and the inner fabric 12 are both made of elastic and breathable fabric cut in one piece;

[0063] More specifically, in this embodiment, liquid elastic colloid is applied to the corresponding position of the outer fabric 11 or the inner fabric 12 using a glue applicator, and after curing, the adhesive strip 5 is formed.

[0064] Specifically, the adhesive strip 5 is fixed between the outer fabric 11 and the inner fabric 12 by hot pressing or adhesive bonding;

[0065] It should be noted that: such as Figure 4-5 As shown, in the actual manufacturing process, the adhesive strip 5 output by the glue applicator is aligned with the edge of the bra to form the first elastic patch structure 3 and the second elastic patch structure 4.

[0066] Specifically, the width of the adhesive strip 5 is in the range of 3-5mm, and is preferably 4mm in this embodiment.

[0067] Specifically, each of the adhesive strip portions 5 is a continuous straight line, a wavy line, or a sawtooth shape, and in this embodiment, a straight line shape is preferred;

[0068] Among them, the straight shape can achieve advantages such as directional guidance, efficient stretching, simple processing and low cost; the wavy shape has advantages such as multi-directional elasticity and aesthetics; the serrated shape has better tear resistance. When the material is subjected to lateral or oblique stress, the force is dispersed in multiple directions, making it extremely difficult for the adhesive strip 5 to cause "stress concentration" between the fabric and the adhesive strip to lead to delamination or tearing.

[0069] Specifically, the width of the breathable part 6 is in the range of 2-3mm, and in this embodiment it is preferably 2mm.

[0070] Specifically, the front collar portion 14 is cut in the transverse direction, and the adhesive strip portion 5 and the breathable portion 6 are arranged alternately on the cut surface of the front collar portion 14;

[0071] The bending portion 15 is cut laterally, and the rubber strip portion 5 and the breathable portion 6 are arranged alternately on the cut surface of the bending portion 15.

[0072] Specifically, on the edge cross-sections of the front collar portion 14 and the bending portion 15, the adhesive strip portion 5 and the breathable portion 6 are arranged in an alternating manner.

[0073] like Figure 2 , Figure 4 and Figure 9 As shown, the front part 1 includes a first side panel 16 and a second side panel 19 symmetrically arranged on the left and right. Each side panel and the lower part 18 are provided with an adhesive edge 7, which is sandwiched between the outer fabric 11 and the inner fabric 12.

[0074] The adhesive edge 7 extends from the upper end of the first side 16 to the lower end, then extends along the lower circumference 18 to the lower end of the second side 19, and finally extends to the upper end of the second side 19, forming a U-shaped structure.

[0075] It should be noted that the design of the rubber edge 7 and the U-shaped structure makes the lower part 18 or the side panel have the effect of controlling elasticity, that is, the lower part 18 or the side panel has low elasticity or no elasticity, so that the lower part 18 has enough support to support the breast, and the side panel can also tuck in some of the accessory breast tissue.

[0076] As shown in Figure 6 , the face fabric 11, the rubber edge 7 and the lining fabric 12 at the edge of the underband 18 can be clearly seen;

[0077] Furthermore, after the face fabric 11 and the lining fabric 12 are bonded via the rubber edge 7, edge cracking between the underband 18 and the side wings can be avoided.

[0078] Specifically, it further comprises a rear band portion 2 for fitting against the back, and the left and right sides of the rear band portion 2 are correspondingly connected integrally with the two side wings of the front band portion 1 respectively.

[0079] Specifically, it further comprises two shoulder straps 8; one end of each shoulder strap 8 is detachably connected to the front band portion 1, and the other end of the shoulder strap 8 extends to be detachably connected to the rear band portion 2.

[0080] Specifically, the left and right ends of the front neck portion 14 are connected to the underarm portions 15 on the left and right sides respectively, and sharp points 17 are formed at the connecting positions; each of the sharp points 17 extends and narrows in the direction away from the cup portion 13;

[0081] More specifically, a plurality of adhesive strip portions 5 on the front neck portion 14 and the underarm portions 15 on both sides are arranged at intervals in sequence to form a herringbone structure;

[0082] In this embodiment, through the upwardly extending and alternately arranged adhesive strip portions 5 and breathable portions 6, as well as the design of the herringbone structure, the originally integral structure is divided into a plurality of elastic units that can independently slightly stretch and contract; when the chest rises and falls or the arms move, the adhesive strip portions 5 provide the main transverse stretching and restoring force, while the unrestrained areas of the breathable portions 6 allow the fabric to extend freely, thereby significantly increasing the overall elastic deformation capacity of the front neck portion 14 and the underarm portions 15. This enables the front neck portion 14 to stretch naturally with breathing and movement, completely avoiding a sense of oppression; the underarm portions 15 can also flexibly adapt to different arm circumferences and shoulder widths, eliminating friction and strap marks.

[0083] Specifically, the sharp points 17 are used to connect the shoulder straps 8;

[0084] More specifically, by providing hooked portions at the sharp points 17, and 9-shaped hooks are provided at the ends of the shoulder straps 8, the 9-shaped hooks are detachably connected with the hooked portions.

[0085] As shown in Figure 8-9 , the face fabric 11 and the lining fabric 12 are not adhesively connected in the partial regions corresponding to the two cup portions 13, so as to form cavities for placing inner cup pads 131;

[0086] In the actual manufacturing process, by making two slits in the lining fabric 12, the inner cup pad 131 can be inserted into the cavity, and then the slits can be glued to one side of the inner cup pad 131 to fix the inner cup pad 131.

[0087] As shown in the figure Figure 4 As shown, when the glue applicator applies glue to the outer fabric 11 or the inner fabric 12, it leaves multiple ventilation holes 91 at the underside 9 and the center section of the front part 1. No adhesive is placed inside the ventilation holes 91, and the edges of the ventilation holes 91 are connected to the adhesive. The outer fabric 11 and the inner fabric 12 are bonded together with adhesive, which not only ensures the basic connection function, but also makes the underside 9 and the center section more breathable.

[0088] Example 2

[0089] like Figure 10-12 As shown, this embodiment also provides a bra with a highly elastic and breathable patch structure. Features not explained in this embodiment can be explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0090] In the actual manufacturing process, if the adhesive strip 5 output by the glue applicator does not reach the edge of the bra, after the outer fabric 11 and the lining fabric 12 are bonded together, the upper edges of the front neckline 14 and the curved portion 15 need to be trimmed to form the first elastic patch structure 3 and the second elastic patch structure 4. This not only prevents the edges of the front neckline 14 and the curved portion 15 from splitting, but also forms an elastic patch structure with the adhesive strip 5 and the breathable portion 6 arranged alternately.

[0091] Example 3

[0092] like Figure 13-15 As shown, this embodiment also provides a bra with a highly elastic and breathable patch structure. Features not explained in this embodiment can be explained using the methods in Embodiments 1 and 2, and will not be repeated here. The difference between this embodiment and Embodiments 1 and 2 is:

[0093] In actual production, instead of using a glue-applying machine to directly apply glue to the outer fabric 11 or the inner fabric 12, a one-piece sheet adhesive layer 10 is used. The sheet adhesive layer 10 has multiple hollow holes 101 at different positions. The hollow holes 101 extending vertically upward on the front collar 14 and the bent part 15 form the breathable part 6.

[0094] It should be noted that in actual processes, perforation equipment is usually used to make holes in this sheet-like adhesive layer 10, so the edges of this sheet-like adhesive layer 10 will have their own sealing adhesive. Therefore, after the outer fabric 11 and the inner fabric 12 are bonded together, the upper edges of the front collar 14 and the bent part 15 need to be trimmed so that an alternating arrangement of adhesive strip 5 and breathable part 6 can be formed on the edge cross section.

[0095] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
