Description

A strapless push-up bra with a combination front clasp Technical Field

[0001] This application belongs to the field of underwear technology, specifically relating to a strapless push-up bra with a combined front clasp. Background Technology

[0002] Strapless bras are underwear that covers and secures the breasts without the need for shoulder straps. They liberate women from the constraints of traditional bra straps, avoiding the marks they leave on the body, and have gained popularity among women. Strapless bras are especially indispensable for women when wearing off-the-shoulder clothing, formal gowns for special occasions, or everyday summer attire.

[0003] However, despite the popularity of strapless bras in the market, there are still many problems with the existing technology that need to be solved:

[0004] First, insufficient anti-slip performance is one of the main challenges currently facing strapless bras. Due to the lack of shoulder strap support, strapless bras are prone to slipping down during use, affecting the wearer's wearing experience and overall image.

[0005] Secondly, strapless bras do not provide enough support for the breasts, resulting in poor breast enhancement after wearing. In order to solve the problem of insufficient support, some strapless bras will add a strap at the front. However, this extra strap design is often not secure and is prone to loosening in a short time, ultimately failing to effectively improve the problem of poor breast enhancement.

[0006] Finally, the multi-section back clasp design of conventional strapless bras presents difficulties in positioning and fastening because the wearer cannot see it directly. For example, Chinese patent CN204048067U discloses a strapless invisible bra, which also mentions that the fasteners are usually located on the back, and when wearing it, one can only try to fasten it by touching it with their fingers, which is very inconvenient. The aforementioned prior art not only has back clasps but also transparent patches, which is quite unfriendly to users who have allergies to adhesives.

[0007] To address the issue of multiple hook-and-eye closures on the back of bras making them difficult to position and fasten, some strapless bras have been developed with hooks placed at the front for easier fastening. However, these products still have some shortcomings.

[0008] If the single buckle is located at the underband, it cannot effectively restrain or limit the upper edges of the two cups. Due to the lack of necessary support and fixation, the upper edges of the cups are prone to turning outwards during wear. This not only affects the overall aesthetics of the bra, but may also reduce the comfort and stability of wearing it. At the same time, the design of the underband being too tight and non-adjustable further restricts the wearer's comfort and freedom.

[0009] If the single clasp is placed between the two cups, the underbust area will not provide sufficient support for the two breasts, thus preventing the entire breast from achieving the desired lift effect. Summary of the Invention

[0010] In response to the problems in related technologies, this application proposes a strapless push-up bra with a combined front clasp to overcome the aforementioned technical problems in existing related technologies. This application achieves the effects of push-up, chest support, and anti-slippage by working together with a low-elasticity small buckle, an adjustable large buckle, and an elastic back strap.

[0011] The technical solution of this application is implemented as follows: a strapless push-up bra with a combined front buckle, including a bra body, the bra body including two cups disposed at the front, and a back band connecting the two cups into one piece;

[0021] Furthermore, one end of the hook is exposed on the surface of the underside and used to engage with the hooked portion, while the other end of the hook is embedded between the inner layer and the outer layer.

[0022] Furthermore, the low-elasticity buckle includes a female buckle and a female buckle that interlock with each other, and the female buckle has at least one locking position; both the female buckle and the female buckle are connected to the corresponding bra cup through a low-elasticity buckle strap, and the elasticity of the low-elasticity buckle strap is lower than that of the elastic back strap.

[0023] Furthermore, the back band is a double-layered, low-elastic structure without a back clasp located on the back of the bra body; the elastic back strap is provided with an adjustable buckle; the elasticity of the elastic back strap is greater than that of the back band.

[0024] Furthermore, the rear shoulder strap includes an inner and an outer skin-contact layer and a fabric layer, and the elastic back strap is disposed on the skin-contact layer;

[0025] The fabric layer and the skin-adhesive layer are bonded together along their upper and lower edges to form an upper portion and a lower portion, respectively; the fabric layer and the skin-adhesive layer form a non-bonded cavity between the upper portion and the lower portion;

[0026] The elastic shoulder strap has an inner and outer double-layer elastic structure; one side of the skin-contact layer is a skin-contact, non-slip surface.

[0027] The skin-adhesive layer includes two positioning portions, each containing a positioning cartilage; when worn, each positioning portion is in close contact with the underarm skin.

[0028] Both ends of the elastic shoulder strap extend at least to the positioning portion.

[0029] It should be noted that, in this application, the two ends of the elastic shoulder strap can be connected to the positioning part by a detachable buckle, or by adhesive or sewing.

[0030] Furthermore, the bra cup includes an outer cup surface and an inner cup surface, the inner cup surface being for contact with the skin of the chest;

[0031] Each of the side panels is connected to the side edge of the inner cup surface of the corresponding bra cup, forming an inner arc transition line on the inner cup surface, and an outer arc transition line on the outer fabric layer; each arc transition line extends from the upper edge of the bra cup to the lower edge of the underband; when worn, both the inner and outer arc transition lines cover the side edges of the breast.

[0032] Furthermore, on the same side, the skin-adhesive layer is provided with a plurality of anti-slip lines spaced apart between the inner arc transition line and the positioning part.

[0033] Furthermore, each of the anti-slip lines is an arc that protrudes towards the positioning part.

[0034] Furthermore, each of the cups has an airbag strip in the interlayer at the bottom.

[0035] Furthermore, the airbag strip is in the shape of a curved arc.

[0036] Furthermore, the lower edge of each of the lower plates is wavy, and after the adjustable buckle is fastened, the connection between the left and right lower plates forms an upward convex curve.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0049] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] As shown in Figures 1-4, this embodiment provides a strapless push-up bra with a combined front clasp, including a bra body, the bra body including two cups 1 located at the front, and a back band 2 connecting the two cups 1 into one piece;

[0051] The inner sides of the two cups 1 that are close to each other are connected by a low-elasticity small buckle 4 and an adjustable large buckle 5.

[0052] More specifically, the low-elasticity small buckle 4 and the adjustable large buckle 5 are distributed on the inner side of the two cups 1 that are close to each other, one above the other.

[0053] The bra body also includes underbands 3 on the left and right sides, and the underbands 3 are respectively provided on the lower side of the two cups 1; the adjustable buckle 5 is fixed at the position where the two underbands 3 are close to each other.

[0054] More specifically, the lower edges of the two cups 1 are respectively connected to the upper edges of different underbands 3;

[0055] The two ends of the back band 2 are respectively connected to the outer sides of the two cups 1 to form a side panel 23 that wraps around the accessory breast.

[0056] The inner side of the rear band 2 is provided with an elastic back strap 6 for adjusting the tightness.

[0057] It should be noted that after the low-elasticity small buckle 4 and the adjustable large buckle 5 are connected in sequence, the tightening connection of the adjustable large buckle 5 will cause the upper part of the two cups 1 to be stretched laterally outward of the chest. At this time, the back band 2 is tightened laterally by tightening the elastic back strap 6, and the back band 2 then tightens the upper part of the two cups 1 laterally.

[0058] First, this embodiment features a combined front clasp, where the low-elasticity small clasp 4 connects the two cups 1, and the adjustable large clasp 5 adjusts the length of the underband 3. Through the cooperation of the combined front clasps, users can quickly put on the strapless push-up bra, avoiding the inconvenience of traditional back clasp designs. The strapless push-up bra described in this embodiment is more convenient and practical.

[0059] Secondly, the low-elasticity small buckle 4 guides the breasts towards the center when worn, thus creating a fuller, more three-dimensional breast line and preventing the cups 1 from flipping forward. At the same time, the adjustable large buckle 5 can flexibly adjust the length of the underband 3 to adapt to different wearers' underbust sizes. This design not only improves the applicability of the bra but also ensures comfort and fit when worn. The adjustable large buckle 5 also enhances the tightness of the connection between the two underbands 3, improves the support of the underbands 3 for the cups 1, effectively prevents the cups 1 from slipping down during wear, and further enhances the stability and wearing effect of the bra.

[0060] Finally, the elastic back strap 6, as part of the bra body, can laterally tighten the back band 2 through its elastic adjustment function. The back band 2 further tightens the two cups 1 laterally, thereby effectively preventing the bra body from slipping down during wear.

[0061] In summary, this embodiment, through the synergistic cooperation of the low-elasticity small buckle 4, the adjustable large buckle 5, and the elastic back strap 6, enables the strapless push-up bra to maintain comfort and freedom of movement while achieving the effects of push-up, chest support, and anti-slippage without the need for shoulder straps.

[0062] In addition, this embodiment uses a side panel 23 that is thinner than the cup 1 to wrap the accessory breast, which can tighten the accessory breast and avoid excessive pressure on it, thus further improving the comfort of wearing it.

[0063] Specifically, the adjustable buckle 5 includes a single-row buckle, a multi-row buckle, a single buckle, or a retractable buckle.

[0064] It should be noted that this embodiment does not limit the type of the adjustable large buckle 5, and various buckle types that can adjust the length of the underpin 3 have the same technical effect; nor does it limit the specific number of rows of buckles, and single rows and multiple rows have the same technical effect.

[0065] Specifically, the adjustable buckle 5 includes a hook 51 and a hooked part 52 that interlock with each other, wherein the hooked part 52 has at least two rows; the hook 51 and the hooked part 52 are respectively connected to the lower puller 3 on different sides by means of fitting or sewing.

[0066] More specifically, the hooked part 52 includes a hook ring 521 connected to the hook and a limiting part; the underband 3 includes an inner layer 32 and an outer layer 31 connected to the inside and outside, the outer layer 31 and the cup 1 are integrally formed molded cup, one side of the inner layer 32 is a skin-friendly non-slip surface; one side of the outer layer 31 of the underband 3 has an opening for the hook ring 521 to pass through, and the limiting part is embedded between the inner layer 32 and the outer layer 31.

[0067] More specifically, one end of the hook 51 is exposed on the surface 31 of the lower stripe 3 on the other side and is used to engage with the hooked part 52, while the other end of the hook 51 is embedded between the inner layer 32 and the surface layer 31.

[0068] It should be noted that in this embodiment, the hook 51 and the hooked part 52 are preferably connected to the lower stripe 3 by means of adhesion. Compared with the traditional sewing method, adhesion can reduce the number of sutures, thereby avoiding friction between the sutures and human skin. Moreover, the limiting part, hook 51, etc. are embedded between the inner layer 32 and the outer layer 31, making the hook 51 and the hooked part 52 more invisible and aesthetically pleasing.

[0069] Specifically, the low-elasticity buckle 4 includes a female buckle and a female buckle that are interlocked. The female buckle has at least one locking position. Both the female buckle and the female buckle are connected to the corresponding bra cup 1 through a low-elasticity buckle strap 41. The elasticity of the low-elasticity buckle strap 41 is lower than that of the elastic back strap 6.

[0070] The low-elasticity buckle 41, with its moderate elasticity, allows the two cups 1 to guide the breasts towards the center when worn, and also has a certain degree of stability, which can prevent the cups 1 from shifting due to external force or movement, ensuring the long-lasting and stable wearing effect of the underwear.

[0071] Specifically, the back band 2 is a double-layered, low-elastic structure without back clasps located on the back of the bra body; the elastic back strap 6 is provided with an adjustable buckle 61; the elasticity of the elastic back strap 6 is greater than that of the back band 2.

[0072] The lateral elastic tension of the elastic back strap 6, combined with the elastic contraction of the back band 2, allows the front of the bra to fit snugly against the chest and the back to fit snugly against the back, further enhancing the gathering and anti-slipping effect of the strapless push-up bra.

[0073] Specifically, the rear shoulder strap 2 includes an inner and outer skin-contact layer 22 and a surface fabric layer 21, and the elastic back strap 6 is disposed on the skin-contact layer 22.

[0074] The fabric layer 21 and the skin-adhesive layer 22 are attached to each other along their upper and lower edges, forming an upper portion and a lower portion respectively; the fabric layer 21 and the skin-adhesive layer 22 form a non-attached cavity between the upper portion and the lower portion.

[0075] The elastic shoulder strap 6 has an inner and outer double-layer elastic structure; one side of the skin-contact layer 22 is a skin-contact, non-slip surface.

[0076] The skin-adhesive layer 22 includes two positioning parts 9, each of which has a positioning cartilage 91 embedded therein; when worn, each of the positioning parts 9 is in close contact with the underarm skin.

[0077] In this embodiment, the positioning part 9 plays a crucial role in fixing and preventing slippage in the design of the back band 2. The positioning part 9 has a built-in positioning cartilage 91, a design that allows it to fit snugly against the underarm skin during wear, forming a stable support point. Because the positioning cartilage 91 has a certain degree of rigidity and support, it effectively prevents the back band 2 from sliding or shifting during dynamic activities, thus ensuring that the back band 2 always remains in the correct position, providing continuous comfort and support.

[0078] Specifically, both ends of the elastic shoulder strap 6 extend at least to the positioning part 9; it should be noted that, in this embodiment, both ends of the elastic shoulder strap 6 can be connected to the positioning part 9 by a detachable connecting buckle, or by adhesive or sewing.

[0079] Specifically, the bra cup 1 includes an outer cup surface 11 and an inner cup surface 12, the inner cup surface 12 being used to contact the skin of the chest.

[0080] Each of the side panels 23 is connected to the side edge of the inner cup surface 12 of the corresponding bra cup 1, and forms an inner arc transition line 7 on the inner cup surface 12, while forming an outer arc transition line 8 on the outer fabric layer 21; each arc transition line extends from the upper edge of the bra cup 1 to the lower edge of the underband 3; when worn, both the inner and outer arc transition lines 8 cover the side edge of the breast.

[0081] The inner and outer curved transition lines 8 significantly shorten the horizontal width of the traditional cup 1. At the same time, the side panels 23, which are thinner than the cup 1, are used to wrap the accessory breast. This can tighten the accessory breast and avoid excessive pressure on it, thereby reducing friction on the underarm skin and further improving the comfort of wearing it.

[0082] Specifically, on the same side 23, the skin-adhesive layer 22 is provided with a plurality of anti-slip lines 231 spaced apart between the inner arc transition line 7 and the positioning part 9.

[0083] More specifically, each of the anti-slip lines 231 is an arc protruding toward the positioning part 9.

[0084] In this embodiment, each of the anti-slip lines 231 is formed by a brushing process. It is mainly used to tighten the fat under the armpit and the accessory breast, and can also improve the support of the side strip 23, making the side strip 23 more stable and less prone to deformation.

[0085] Specifically, each of the cups 1 has an airbag strip 13 in the interlayer at the bottom.

[0086] More specifically, the airbag strip 13 is in the shape of a curved arc.

[0087] In this embodiment, an airbag strip 13 is used instead of a traditional steel wire to fix and support the bra cup 1, so that the bra cup 1 neither rides up nor slips down, further improving the gathering effect on the breasts.

[0088] Specifically, the lower edge of each of the underarm 3 is wavy, and after the adjustable buckle 5 is fastened, the connection between the left and right sides of the underarm 3 forms an upward convex curve to fit the lower edge of the human chest.

[0089] Specifically, it also includes detachable shoulder straps. The bra body is provided with several ear loops 10 that are connected to the detachable shoulder straps, so that the bra body has multiple wearing methods. It can be used as a strapless bra or as a bra with shoulder straps.

[0090] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this application should also fall within the protection scope of the claims of this application. 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 application.
