Description

Technical Field

[0001] This utility model belongs to the field of underwear technology, specifically relating to a nursing bra with lateral expansion. Background Technology

[0002] In the field of maternal and infant products, to meet the special needs of breastfeeding women, various bras specifically designed for postpartum breastfeeding have appeared on the market. Currently, most nursing bras adopt an openable cup structure to facilitate breastfeeding at any time. For example, Chinese patent CN203934673U discloses a nursing bra that includes two symmetrically arranged cups, shoulder straps, a band sewn to the lower edge of the cups, and hooks and fasteners at both ends of the band. It also includes two side support panels located inside the two cups, which are sewn to the arc-shaped outer edge of the corresponding cup away from the center of symmetry. This bra achieves side support and shaping functions through the side support panels, avoiding the use of rigid materials and improving wearing comfort to a certain extent.

[0003] However, in practical applications, this existing technology still has shortcomings: the breast volume of breastfeeding women changes significantly with physiological changes, especially during peak lactation, when the breasts not only increase in the front-to-back direction but also show obvious lateral expansion. Most existing nursing bras have a fixed-volume cup structure with poor lateral elasticity. This design easily leads to breast spillage and compresses the mammary glands, affecting not only wearing comfort but also potentially posing a threat to women's breast health. Furthermore, the insufficient lateral support of existing bras can easily cause a series of problems such as loose breast shape and body shape loss. The aforementioned existing technology also cannot make lateral expansion adjustments according to changes in breast size during lactation, lacking flexibility. When the breasts enlarge, the lateral pressure is strong, further reducing wearing comfort and potentially affecting breast health. Summary of the Invention

[0004] In response to the problems in related technologies, this utility model proposes a lateral expansion nursing bra to overcome the aforementioned technical problems existing in the prior art. By setting up first and second expansion structures, this utility model helps to meet the bra capacity needs of women at different physiological stages. At the same time, the lateral expansion method avoids the problem of chest compression caused by unreasonable expansion direction, thus improving the wearing comfort of the nursing bra.

[0005] The technical solution of this utility model is implemented as follows: a lateral expansion nursing bra, including a bra body; the bra body includes a bra portion and a lower band connected to the lower edge of the bra portion; the bra portion includes a first cup and a second cup arranged symmetrically on the left and right.

[0006] The bra portion and the underband are provided with a first expansion structure and a second expansion structure. The first expansion structure extends from top to bottom along the left side of the first cup, and the second expansion structure extends from top to bottom along the right side of the second cup.

[0007] Each of the aforementioned expansion structures includes a first connecting part, a second connecting part, and a third connecting part arranged sequentially. The first connecting part and the second connecting part are connected by a first elastic expansion sheet, and the second connecting part and the third connecting part are connected by a second elastic expansion sheet. Each of the aforementioned elastic expansion sheets is a breathable expansion mesh structure, and the mesh structure is woven from multiple elastic materials.

[0008] When the first connecting part is used as the outer circumference supporting the breast, the first elastic expansion piece, the second connecting part, and the second elastic expansion piece serve as a structure that wraps around the chest cavity; when the third connecting part is used as the outer circumference supporting the breast, the first elastic expansion piece, the second connecting part, and the second elastic expansion piece serve as a cup structure that wraps around the breast, and at this time, each of the elastic expansion pieces is stretched and deformed laterally to increase the capacity of the bra part.

[0009] Furthermore, the bra body includes an outer fabric layer, a soft support layer, and an inner fabric layer stacked in sequence; the outer fabric layer and the inner fabric layer are separated at positions corresponding to the first cup and the second cup, respectively forming two independent cavities; each cavity is provided with a breast pad;

[0010] Furthermore, the lower edge of each of the breast pads is fixedly connected to the lining layer;

[0012] Furthermore, the outer fabric layer has first expansion holes at positions corresponding to the first expansion structure and the second expansion structure, respectively;

[0013] The lining layer has second expansion holes at positions corresponding to the first expansion structure and the second expansion structure, respectively;

[0014] Each of the expansion holes extends along the length direction of the corresponding expansion structure.

[0015] Furthermore, the outer fabric layer, the soft support layer, and the inner fabric layer are all independently cut pieces;

[0016] The soft support layer is made of sandwich elastic fabric, and the elasticity of the outer and inner fabric layers is higher than that of the sandwich elastic fabric.

[0017] Furthermore, the bra body also includes a fixing patch, on which a third expansion hole is provided, the third expansion hole extending along the length direction of the corresponding expansion structure; after the outer fabric layer, soft support layer and inner fabric layer are sequentially attached, the first connecting part and the third connecting part are respectively connected between the fixing patch and the inner fabric layer;

[0018] One side of the second connecting portion is exposed to the first expansion hole, and the other side is exposed to the third expansion hole;

[0019] It should be further explained that: the outer fabric layer, the soft support layer and the inner fabric layer are sequentially bonded together, the expansion structure is then placed at the corresponding second expansion hole, the fixing patch is then bonded to the surface of the expansion structure, and finally the first connecting part and the third connecting part are respectively connected between the fixing patch and the inner fabric layer by a heat pressing process.

[0020] Furthermore, the upper edges of the left and right sides of the soft support layer are respectively provided with clearance grooves at the positions corresponding to the first expansion structure and the second expansion structure; each clearance groove extends along the length direction of the corresponding expansion structure.

[0021] Furthermore, the shape of each expansion structure is arc-shaped, straight-line-shaped, or wavy.

[0022] Furthermore, the first connecting part, the second connecting part, and the third connecting part are also mesh structures, and the mesh diameter on each connecting part is smaller than the mesh diameter on each elastic expansion piece; in this utility model, elastic bands are preferred.

[0023] Furthermore, the bra body also includes two shoulder straps, and the upper edge of each cup is detachably connected to the front end of the shoulder strap on the same side through a first movable connector; an inner strap is also provided on the side of the bra body that is in contact with the skin; one end of the inner strap is connected to the front end of the shoulder strap, and the other end is connected to the underbust.

[0024] Furthermore, the first movable connector includes, but is not limited to, a snap fastener connection structure, a hook fastener connection structure, and a clasp connection structure;

[0025] Furthermore, each of the bra cups has a female buckle on its upper edge and a female buckle on the front end of the shoulder strap on the same side, and the female buckle and the female buckle are detachably connected.

[0026] Furthermore, each of the inner straps has a built-in support strip, and the support strip extends along the length direction of the inner strap; the elasticity of the support strip is less than the elasticity of the inner strap;

[0027] Furthermore, each of the inner bands has at least two support bars built in, and the two support bars are arranged in parallel or approximately parallel order.

[0028] Furthermore, each of the said side sections is provided with a side bone, which is made of cloth strips;

[0029] Furthermore, each of the lateral bones extends from the lower edge of the lower circumference toward the upper edge of the lower circumference.

[0030] The beneficial effects of this utility model are:

[0032] (2) Each elastic expansion piece is a breathable expansion mesh structure. This mesh design greatly increases the breathable area of ​​the bra, allowing air to circulate freely inside the bra, effectively reducing the stuffiness and dampness of the chest skin, and reducing the risk of skin problems caused by wearing non-breathable bras for a long time, providing women with a more comfortable and healthy wearing experience.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Example 1

[0049] like Figure 1-4 As shown, this embodiment provides a laterally expandable nursing bra, including a bra body 1; the bra body 1 includes a bra portion 11 and a lower band 12 connected to the lower edge of the bra portion 11; the bra portion 11 includes a first cup 111 and a second cup 112 arranged symmetrically on the left and right.

[0050] A first expansion structure 2 and a second expansion structure 3 are provided at the junction of the bra part 11 and the lower band 12. The first expansion structure 2 extends from top to bottom along the left side of the first cup 111, and the second expansion structure 3 extends from top to bottom along the right side of the second cup 112.

[0051] like Figure 7 As shown, each of the expansion structures includes a first connecting part 21, a second connecting part 23, and a third connecting part 25 arranged sequentially. The first connecting part 21 and the second connecting part 23 are connected by a first elastic expansion piece 22, and the second connecting part 23 and the third connecting part 25 are connected by a second elastic expansion piece 24. Each elastic expansion piece is a breathable expansion mesh structure, and the mesh structure is woven from multiple elastic materials.

[0052] When the first connecting part 21 is used as the outer circumference supporting the breast, the first elastic expansion piece 22, the second connecting part 23, and the second elastic expansion piece 24 serve as a structure that wraps around the chest cavity; when the third connecting part 25 is used as the outer circumference supporting the breast, the first elastic expansion piece 22, the second connecting part 23, and the second elastic expansion piece 24 serve as a cup structure that wraps around the breast. In this case, each of the elastic expansion pieces is stretched and deformed laterally to increase the capacity of the bra part 11.

[0053] First, this embodiment achieves lateral flexible adjustment of the bra portion 11's capacity by setting a first expansion structure 2 and a second expansion structure 3, each expansion structure including different connecting parts connected by elastic expansion pieces. When the first connecting part 21 is used as the outer band supporting the breast, the overall structure can serve as a structure that wraps around the chest cavity; while when the third connecting part 25 is used as the outer band supporting the breast, each elastic expansion piece is stretched and deformed laterally, which can effectively increase the capacity of the bra portion 11, meeting the needs of women for bra capacity at different physiological stages (such as the gradual increase in breast size during pregnancy, the fullness of breasts during lactation, etc.), and avoiding discomfort caused by an overly tight bra.

[0054] Secondly, the first expansion structure 2 extends along the left edge of the first cup 111 to the bottom edge, and the second expansion structure 3 extends along the right edge of the second cup 112 to the bottom edge. This lateral expansion design better conforms to the natural shape and growth direction of the human breast. During the expansion process, it can expand along the contour of the side of the breast, allowing the bra to fit the breast better and preventing problems such as bra shifting or compression of other parts of the breast caused by unreasonable expansion direction.

[0055] Furthermore, each elastic expansion piece features a breathable mesh structure woven from multiple elastic materials. This mesh design significantly increases the bra's breathable area, allowing air to circulate freely within the bra and effectively reducing stuffiness and dampness on the chest skin. This lowers the risk of skin problems caused by prolonged wear of non-breathable bras, providing women with a more comfortable and healthier wearing experience. Simultaneously, the use of elastic expansion pieces not only ensures the flexibility and stretchability of the expansion structure but also provides elastic cushioning during bra wear, reducing hard compression on the chest while offering appropriate support. This helps maintain chest stability during exercise or daily activities, improving wearing comfort and the bra's support performance.

[0056] Specifically, the bra body 1 includes an outer fabric layer 4, a soft support layer 5, and an inner fabric layer 6 stacked in sequence; the outer fabric layer 4 and the inner fabric layer 6 are separated at the positions corresponding to the first cup 111 and the second cup 112 and form two independent cavities respectively; each cavity is provided with a breast pad 113.

[0057] More specifically, the lower edge of each of the breast pads 113 is fixedly connected to the lining layer 6;

[0058] Specifically, the lower band 12 includes left and right side panels and a lower band for connecting the two side panels; the soft support layer 5 extends from one side panel through the lower band to the other side panel to enhance the support under the breast.

[0059] like Figure 5 As shown, the outer fabric layer 4 has first expansion holes 41 at positions corresponding to the first expansion structure 2 and the second expansion structure 3, respectively;

[0060] The lining layer 6 has second expansion holes 61 at positions corresponding to the first expansion structure 2 and the second expansion structure 3, respectively;

[0061] Each of the expansion holes extends along the length direction of the corresponding expansion structure.

[0062] Specifically, the outer fabric layer 4, the soft support layer 5, and the inner fabric layer 6 are all independently cut pieces, which makes both the skin-contact and non-skin-contact surfaces of the bra body 1 smooth, seamless, and more skin-friendly.

[0063] More specifically, the soft support layer 5 is made of sandwich elastic fabric, and the elasticity of the outer fabric layer 4 and the inner fabric layer 6 is higher than that of the sandwich elastic fabric, so as to enhance the support of the soft support layer 5.

[0064] like Figure 6As shown, the bra body 1 also includes a fixing patch 7, on which a third expansion hole 71 is provided, and the third expansion hole 71 extends along the length direction of the corresponding expansion structure; after the outer fabric layer 4, the soft support layer 5 and the inner fabric layer 6 are sequentially attached, the first connecting part 21 and the third connecting part 25 are respectively connected between the fixing patch 7 and the inner fabric layer 6.

[0065] One side of the second connecting portion 23 is exposed to the first expansion hole 41, and the other side is exposed to the third expansion hole 71;

[0066] It needs to be further explained that: such as Figure 8 As shown, the outer fabric layer 4, the soft support layer 5, and the inner fabric layer 6 are sequentially bonded together. Then, the expansion structure is placed at the corresponding second expansion hole 61. Next, the fixing patch 7 is bonded to the surface of the expansion structure. Finally, the first connecting part 21 and the third connecting part 25 are respectively connected between the fixing patch 7 and the inner fabric layer 6 through a heat pressing process.

[0067] like Figure 5 As shown, the upper edges of the left and right sides of the soft support layer 5 are respectively provided with clearance grooves 51 at the positions corresponding to the first expansion structure 2 and the second expansion structure 3; each clearance groove 51 extends along the length direction of the corresponding expansion structure.

[0068] More specifically, the shape of each of the expansion structures includes, but is not limited to, an arc shape, a straight line shape, or a wavy shape.

[0069] Specifically, the first connecting part 21, the second connecting part 23 and the third connecting part 25 are also mesh structures, and the mesh diameter on each connecting part is smaller than the mesh diameter on each elastic expansion piece; in this embodiment, elastic bands are preferred.

[0070] like Figure 1-4 As shown, the bra body 1 also includes two shoulder straps 8, and the upper edge of each cup is detachably connected to the front end of the shoulder strap 8 on the same side through a first movable connector 9; an inner strap 10 is also provided on the skin-contacting side of the bra body 1; one end of the inner strap 10 is connected to the front end of the shoulder strap 8, and the other end is connected to the underband 12.

[0071] Specifically, the first movable connector 9 includes, but is not limited to, a snap fastener connection structure, a hook fastener connection structure, and a clasp connection structure;

[0072] More specifically, each of the bra cups has a female buckle at the upper edge and a female buckle at the front end of the shoulder strap 8 on the same side, and the female buckle and the female buckle are detachably connected;

[0073] It should be noted that while existing bras have adjustable straps that allow for length adjustments, the straps and cups are not detachable. This design limits the bra's usability. During breastfeeding, users must remove both the shoulder strap and cup on one side to expose the breast, which is extremely inconvenient. In this embodiment, the design of the first movable connector 9 and the inner strap 10 allows the user to easily separate the cup from the shoulder strap 8 simply by unhooking the clasp. The shoulder strap 8 remains stationary under the traction of the inner strap 10, facilitating breastfeeding. Furthermore, the inner strap 10 remains stably positioned at the front of the breast, continuing to support the breast even when the cup and shoulder strap 8 are separated, thus reducing breast sagging.

[0074] Specifically, each of the said lateral sides is provided with a lateral bone 13, which is made of cloth strips;

[0075] More specifically, each of the lateral bones 13 extends from the lower edge of the lower periphery 12 toward the upper edge of the lower periphery 12.

[0076] Example 2

[0077] like Figure 9-11 As shown, this embodiment also provides a lateral expansion nursing bra. 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:

[0078] The other end of the inner strap 10 is fixed between the soft support layer 5 and the inner fabric layer 6.

[0079] Each of the inner straps 10 has a built-in support strip 101, and the support strip 101 extends along the length direction of the inner strap 10; the elasticity of the support strip 101 is less than the elasticity of the inner strap 10.

[0080] More specifically, each of the inner bands 10 has at least two support bars 101 built in, and the two support bars 101 are arranged in parallel or approximately parallel.

[0081] The design of the support strip 101 helps to further enhance the support performance of the inner strap 10; after the bra body 1 has been used for a long time, it can effectively prevent the inner strap 10 from deforming due to factors such as stress and aging, and ensure that the inner strap 10 can always provide reliable support for the breast, thereby maintaining the product's performance and comfort.

[0082] 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.
