[0002] This application claims priority to Chinese Patent No. 202520159965.9, filed on January 22, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of maternal and infant products technology, and in particular to a nursing garment. Background Technology

[0004] When using a breast pump, mothers must use their hands to cover the exposed parts of their breasts with breast flanges or breast shields. Because expressing milk with a breast pump takes a long time, mothers often express milk from both breasts simultaneously. To express milk from both breasts, the mother must hold the breast flanges or shields with both hands, placing them in an awkward position and making it difficult to perform even simple actions like operating a breast pump. Therefore, breastfeeding women cannot fully utilize their hands to perform other tasks. Developing a device that allows mothers to use a breast pump while still being able to freely use their hands for other tasks would be highly beneficial.

[0005] Hands-free breast pumps allow mothers to massage their breasts simultaneously to promote milk flow, something most current breast pumps cannot do, or allow mothers to perform other tasks while pumping. To mitigate the disadvantages of holding a breast pump while expressing milk, supportive or nursing garments are available. These typically consist of at least two layers: an inner opening to create a channel for breastfeeding or inserting the breast pump, and an outer layer that covers the inner layer for privacy when worn normally.

[0006] Traditional nursing gowns suffer from problems such as inconvenience in disassembly or discomfort in wearing. When the connecting buckles are designed to be small, they may interfere with each other, causing the buckles to press against the body and causing discomfort. Furthermore, the inner and outer layers are not easy to disassemble or connect, especially when the buckles on the shoulder straps are connected to the inner and outer layers at the same time. The buckles tend to pile up, making disassembly inconvenient and resulting in poor comfort.

[0007] Application content

[0008] In view of the shortcomings of the existing technology, this application provides a nursing garment that can solve the problems of unsmooth disassembly and connection of the layers of the nursing garment, as well as the problem of discomfort when wearing it.

[0009] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a nursing garment, the nursing garment comprising: a shoulder strap, on which a first connecting structure is provided; a first layer, on which a second connecting structure is provided; a second layer, on which a third connecting structure and perforations are provided, the perforations being configured to allow the second connecting structure to pass through the perforations and be detachably connected to the third connecting structure; and a fourth connecting structure on which the second layer is further provided, the fourth connecting structure being configured to be detachably connected to the first connecting structure, so that the first layer and the second layer can be detached together from the shoulder strap, thereby at least partially exposing the wearer's breasts.

[0010] In one embodiment, the shoulder strap is further provided with a fifth connecting structure, which is configured to be detachably connected to the second connecting structure, such that the second connecting structure can be connected to the fifth connecting structure after being detached from the third connecting structure and pulled out of the perforation.

[0011] In one embodiment, the first layer is provided with an opening configured to support at least a portion of a breast pump that is at least partially inserted into the opening, or the opening is configured to allow a user's nipple to be exposed through the opening for breastfeeding.

[0012] In one embodiment, the first layer is closer to the wearer than the second layer when the nursing garment is worn.

[0013] In one embodiment, the second layer is closer to the wearer than the first layer when the nursing garment is worn.

[0014] In one embodiment, a reinforcing strip is provided at the edge of the perforation, and the reinforcing strip is bonded to the second layer by an adhesive film.

[0015] In one embodiment, a reinforcing strip is provided at the edge of the perforation, the reinforcing strip being formed by folding and sewing the second layer at the edge of the perforation.

[0016] In one embodiment, one of the first connecting structure and the fourth connecting structure is a hook structure, and the other is a ring structure, a groove structure, or a hole structure.

[0017] In one embodiment, one of the second connecting structure and the third connecting structure is a hook structure, and the other is a ring structure, a groove structure, or a hole structure.

[0018] In one embodiment, the first connecting structure is a first buckle with a first hook, and the fourth connecting structure is a second buckle with a groove.

[0019] In one embodiment, the third connecting structure is a ring, the second connecting structure is a third buckle, and the third buckle is provided with a second hook.

[0020] In one embodiment, the opening is formed between three edges of the first layer, the three edges at least partially overlapping.

[0021] In one implementation, the elasticity of the three edges is greater than that of other locations in the first layer.

[0022] In one implementation, any two of the three edges are not parallel to each other.

[0023] In one embodiment, the ring is a sewn ring sewn onto the second layer, formed by sewing the two ends of a fabric strip onto the second layer respectively.

[0024] In one embodiment, the loop is formed by attaching the ends of the fabric tape to the second layer.

[0025] In one embodiment, the first layer and the second layer are made of different clothing fabrics.

[0026] In one embodiment, the opening is a slit provided on the first layer.

[0027] In one embodiment, the first layer and the second layer are made of the same clothing fabric.

[0028] In one embodiment, the second connecting structure is disposed at the upper end of the first layer, and the third connecting structure is disposed at the upper end of the second layer.

[0029] This application embodiment describes a nursing garment comprising: shoulder straps with a first connecting structure; a first layer with a second connecting structure; a second layer with a third connecting structure and perforations, the perforations being configured to allow the second connecting structure to pass through and be detachably connected to the third connecting structure; and a fourth connecting structure on the second layer, the fourth connecting structure being detachably connected to the first connecting structure, so that the first and second layers can be detached from the shoulder straps together, thereby at least partially exposing the wearer's breasts. This ensures smooth detachment and connection of the layers of the nursing garment and improves wearing comfort. Attached Figure Description

[0037] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] In this application, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “radial,” and “circumferential” 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 device 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.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0042] Breastfeeding offers numerous benefits for both the infant and the breastfeeding mother. Breast milk contains all the nutrients a baby needs for growth and development. Breastfed babies are generally healthier, with fewer cases of ear infections and respiratory infections, and a lower risk of allergies, cancer, childhood diabetes, and obesity. They are also less likely to develop heart disease, eczema, and asthma. For breastfeeding women, breastfeeding reduces the chances of postpartum hemorrhage and anemia, helps the uterus return to its original size after childbirth, and provides an extra 500 calories per day.

[0043] However, due to work schedules and other time constraints, not every breastfeeding woman can feed her baby on demand. Therefore, many breastfeeding women use breast pumps to express and store breast milk for feeding their infants. A breast pump system typically includes a breast shield, a funnel-shaped device with a conical section that rests against the breast, with the nipple located at the center of the shield. When negative pressure is applied, the nipple is drawn towards the tubular portion of the breast shield, typically into the nipple channel. The nipple channel of the breast shield connects to the other components of the breast milk collection kit. This connection allows for intermittent (i.e., periodic) negative pressure to be applied inside the breast shield, while also providing a flow path for the breast milk expressed into the nipple channel, allowing it to be collected into a collection container. The collection container can be a breast milk container with a threaded cap, which can be used as a feeding bottle for the baby. Breastfeeding women usually need to use their hands to press the breast shield against their breast to express milk.

[0044] Predictably, securing a breast shield is inconvenient and limits what women can do while pumping. Although various bras and corsets have been developed to secure breast shields, these generally do not provide sufficient support and require frequent adjustment.

[0045] In this embodiment, nursing garments can be in the form of bras, tops, shirts, vests, camisoles, pajamas, dresses, or other women's clothing, and are not limited to the bras shown in the figures. Specifically, nursing garments can be in the form of nursing bras, nursing tops, nursing shirts, nursing vests, nursing camisoles, nursing pajamas, nursing dresses, or other women's clothing used for breastfeeding. Nursing garments can also specifically be in the form of breast pump bras, breast pump tops, breast pump shirts, breast pump vests, breast pump camisoles, breast pump pajamas, breast pump dresses, or other women's clothing used to support a breast pump. Nursing garments can specifically combine breast pump and breastfeeding functions. These garments can be breast pump / nursing bras, breast pump / nursing tops, breast pump / nursing shirts, breast pump / nursing vests, breast pump / nursing camisoles, breast pump / nursing pajamas, breast pump / nursing dresses, or other women's clothing designed to support the breast pump or breastfeeding. Nursing garments are designed to allow breastfeeding women to pump or breastfeed without removing the garment.

[0046] The term “connection” is defined as joining, attaching, or closing, although it is not necessarily a direct connection or a mechanical connection. The term “detachment” is defined as disengagement or opening. The term “fastener” generally refers to a bra strap, a device on the first or second layer, from which hooks, buttons, or other detachable connections can be received. The term “breastfeeding” refers to breastfeeding. The term “a” is defined as one or more unless expressly required by this disclosure. The term “comprising” is an open-ended connecting verb.

[0047] In the embodiments of this application, "above" and "below" refer to the positional relationship when the nursing garment is worn on the wearer.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] In this embodiment of the application, a nursing garment is described as a bra. The nursing garment in this embodiment of the application includes a shoulder strap 10, a first layer 20, and a second layer 30.

[0051] As shown in Figures 1, 5, and 6, in some embodiments, the nursing garment may further include a lower chest band 40, which is designed to wrap around the wearer's torso when worn. The lower ends of the first layer 20 and the second layer 30 are connected to the lower chest band 40. Both the first layer 20 and the second layer 30 can be flipped relative to the lower chest band 40.

[0052] As shown in Figures 1 to 6, the shoulder strap 10 is provided with a first connecting structure 11. The first layer 20 is provided with a second connecting structure 21. The second layer 30 is provided with a third connecting structure 31 and a perforation 32, the perforation 32 being configured to allow the second connecting structure 21 to pass through the perforation 32 and be detachably connected to the third connecting structure 31; the second layer 30 is also provided with a fourth connecting structure 33, the fourth connecting structure 33 being detachably connected to the first connecting structure 11, so that the first layer 20 and the second layer 30 can be detached from the shoulder strap 10 together, thereby at least partially exposing the wearer's breasts.

[0053] As shown in Figures 1 to 6, in one embodiment, the first connecting structure 11 may be connected in series with the shoulder strap 10, that is, the two ends of the first connecting structure 11 are respectively connected to different positions of the shoulder strap 10. In other embodiments, the first connecting structure 11 may be connected to the shoulder strap 10 only at one end, and this application embodiment does not limit this.

[0054] In one embodiment, the second connecting structure 21 may be located at the upper end of the first layer 20, and the third connecting structure 31 may be located at the upper end of the second layer 30. In other embodiments, the second connecting structure 21 may be located at other positions of the first layer 20, such as the upper part of the middle; the third connecting structure 31 may be located at other positions of the second layer 30, such as the upper part of the middle. This application does not limit the specific location of the connecting structure 21.

[0055] As shown in Figures 3 and 5, in one embodiment, the shoulder strap 10 is further provided with a fifth connecting structure 12. The fifth connecting structure 12 is configured to be detachably connected to the second connecting structure 21, such that the second connecting structure 21 can be connected to the fifth connecting structure 12 after being detached from the third connecting structure 31 and pulled out of the perforation 32. The second connecting structure 21 is selectively detachably connected to either the fifth connecting structure 12 or the third connecting structure 31, with different connection states adapting to different usage scenarios.

[0056] As shown in Figure 5, in one embodiment, the first layer 20 has an opening 22, which is configured to support at least a portion of a breast pump inserted into the opening 22, or the opening 22 is configured to allow a user's nipple to be exposed through the opening 22 for breastfeeding. In one embodiment, the opening 22 is formed between three edges 23, 24, and 25 of the first layer 20, and the three edges 23, 24, and 25 at least partially overlap. The opening 22 of this embodiment is suitable for supporting the breast pump, and the three edges 23, 24, and 25 provide stable support for the breast pump. These three edges 23, 24, and 25 are located on the inner side of the first layer 20, not on the outer side. Any two of the three edges 23, 24, and 25 are not parallel to each other.

[0057] In one embodiment, the elasticity of the three edges 23, 24, and 25 is greater than that of other locations on the first layer 20. By setting the elasticity of the three edges 23, 24, and 25 to be greater than that of other locations, they can contract when supporting the breast pump, thereby achieving stable support. In some embodiments, the three edges 23, 24, and 25 can be achieved by applying one or more reinforcing strips using an adhesive process, wherein the intermediate adhesive film of the adhesive process is elastic.

[0058] In some embodiments, the opening may also be a slit. In this embodiment, the slit is used to allow the wearer's breast or a portion of the breast (e.g., the nipple) to pass through, thereby enabling breastfeeding.

[0059] It should be understood that the shape and structure of the opening are not limited to those described in the embodiments of this application, as long as they can support the breast pump or allow the nipple to pass through for breastfeeding.

[0060] In one embodiment, the first layer 20 is closer to the wearer than the second layer 30 when the nursing garment is worn. In other embodiments, the second layer may be closer to the wearer than the first layer when the nursing garment is worn.

[0061] In one embodiment, the first layer 20 and the second layer 30 may be made of the same clothing fabric; in other embodiments, the first layer 20 and the second layer 30 may be made of different clothing fabrics. For example, the first layer 20 may be made of a more skin-friendly clothing fabric, while the second layer 30 may be made of a waterproof, abrasion-resistant, or other fabric. This application does not limit the specific application to this embodiment.

[0062] In one embodiment, a reinforcing strip (not shown) is provided at the edge of the perforation 32, and the reinforcing strip is bonded to the second layer 30 by an adhesive film. In another embodiment, the reinforcing strip is provided at the edge of the perforation, and the reinforcing strip is formed by folding and sewing the second layer at the edge of the perforation. The reinforcing strip can prevent the edge of the perforation 32 from wrinkling and deforming, and prevent the perforation 32 from tearing or breaking after prolonged washing.

[0063] In one embodiment, one of the first connecting structure 11 and the fourth connecting structure 33 is a hook structure, and the other is a ring structure, a groove structure, or a hole structure.

[0064] In one embodiment, one of the second connecting structure 21 and the third connecting structure 31 is a hook structure, and the other is a ring structure, a groove structure, or a hole structure.

[0065] In other embodiments, one of the first connecting structure and the fourth connecting structure is the hook side of the hook and loop fastener, and the other is the velvet side of the hook and loop fastener.

[0066] In other embodiments, one of the second connecting structure and the third connecting structure is the hook side of the hook and loop fastener, and the other is the velvet side of the hook and loop fastener.

[0067] In other embodiments, the first connecting structure and the fourth connecting structure may also employ other detachable connecting structures, and this application embodiment does not limit this. The second connecting structure and the third connecting structure may also employ other detachable connecting structures, and this application embodiment does not limit this.

[0068] In one embodiment, the first connecting structure 11 is a first buckle 11 with a first hook 111, and the fourth connecting structure 33 is a second buckle 33 with a groove 331. The first hook 111 and the groove 331 are matched to achieve a detachable connection between the first connecting structure 11 and the fourth connecting structure 33. The groove 331 is approximately U-shaped, thus forming a spring-loaded structure on the inner side of the groove 331, which ensures a certain elastic variation space when the first hook 111 and the groove 331 are connected, improving the smoothness of connection and disassembly.

[0069] In one embodiment, the third connecting structure 31 is a ring 31, and the second connecting structure 21 is a third button 21, wherein the third button 21 is provided with a second hook 211. In one embodiment, the ring 31 may be a sewn ring formed by stitching the two ends of a strap to the second layer 30, or it may be a ring formed by gluing the two ends of a strap to the first layer 20. This application does not limit the specific embodiment to this.

[0070] In this embodiment, the fifth connecting structure 12 and the first connecting structure 11 are different structures located at different positions. The first connecting structure 11 is a hook, and the fifth connecting structure 12 is a ring 12. It should be understood that in other embodiments, the fifth connecting structure and the first connecting structure can be the same structure, that is, the function of the fifth connecting structure can be achieved by using the first connecting structure. In other words, the second connecting structure 21 is selectively and detachably connected to either the first connecting structure 11 or the third connecting structure 31. After the second connecting structure 21 is detached from the third connecting structure 31 and pulled out of the perforation 32, it can be connected to the first connecting structure 11, thereby supporting the first layer 20, and further supporting at least a portion of the breast pump that is at least partially inserted into the opening 22, or the opening 22 is configured to allow the user's nipple to be exposed through the opening 22 for breastfeeding.

[0071] The following detailed description of the usage scenarios of the nursing garments according to the embodiments of this application is provided in conjunction with the accompanying drawings.

[0072] As shown in Figure 2, in one usage scenario, the second connecting structure 21 passes through the perforation 32 and connects to the third connecting structure 31; the fourth connecting structure 33 connects to the first connecting structure 11. In this connection state, the nursing garment is worn normally, with both the first layer 20 and the second layer 30 in a covering state, protecting the wearer's privacy in daily work and life.

[0073] As shown in Figure 5, in one usage scenario, the fourth connecting structure 33 is detached from the first connecting structure 11 on the shoulder strap 11, the second layer 30 is flipped open outwards, the second connecting structure 21 is detached from the third connecting structure 31, and after the second connecting structure 21 is pulled out from the perforation 32, the second connecting structure 31 is connected to the fifth connecting structure 12. In this connected state, the nursing garment is used to support a breast pump through the opening 22 of the first layer 20 or to breastfeed through the opening 22.

[0074] As shown in Figure 4, in one usage scenario, the second connecting structure 21 passes through the perforation 32 and connects to the third connecting structure 31; the fourth connecting structure 33 is detached from the first connecting structure 11. The first layer 20 and the second layer 30 simultaneously flip outwards and open. In this connected state, the nursing garment can fully expose the wearer's breasts for breastfeeding.
