DETAILED DESCRIPTION
(13) A polymeric breast support structure for a bra or other breast support garment (including but not limited to bustiers, sports bras, camisoles, swimwear, shapewear, bodysuits) is herein described. Bras and other bra-related garments are typically worn to cover the breast tissue of the wearer, direct the breast tissue volume into a preferred aesthetic shape, and limit movement of the breast tissue.
(14) The polymeric breast support structure may be included in a bra or other bra-related garment which includes at least the polymeric breast support structure. The bra may further include a fabric body to which the polymeric breast support structure is coupled/sewn in. In some embodiments, two cups may be included, including molded mesh cups, traditional bra cups, or any other suitable structure to provide cups for a bra. The polymeric breast support structure may be lined with fabric before being assembled into a bra. The polymeric breast support structure may be integrated within the bra or bra-related garment using any available methods, including sewing, bonding, the use of underwire channeling, etc. Further, the polymeric breast support can be sewn or bonded directly to the fabric of the garment, whereas a traditional metal underwire (which is indirectly attached via underwire channeling) cannot.
(15) The polymeric material of the polymeric breast support structure may be a thermoplastic, elastomer, thermoplastic elastomer or any other polymeric material. The material may be a single polymeric material or combination of such polymeric materials that provide sufficient flexibility, hardness, strength and elasticity to comfortably support breast tissue. The material is heat resistant to at least 140 degrees Celsius so it is stable for washing and drying as part of a garment laundering process. The polymeric breast support structure may all be made of a uniform material, or alternatively, the various sub-components may be made of various polymeric materials and combined together in a subsequent manufacturing step to fuse/bond/couple the sub-components together to form the polymeric breast support structure. For clarity, the polymeric breast support structure does not incorporate any metallic material.
(16) The polymeric breast support structure may be manufactured using a variety of available manufacturing processes. This may include additive manufacturing methods, such as 3D printing and injection molding, amongst any other suitable alternative manufacturing methods.
(17) The polymeric breast support structure is differentiated from traditional underwire. Unlike flat underwire that exists in a singular plane, the polymeric breast support structure is 3-dimensional with a curvature that follows the inframammary fold of the wearer and accommodates different depths of the sternum, ribs, and side-body for a better, more contoured fit. This 3-dimensional design enhances comfort and tacking while reducing poking and red marks on the body. While the cross-sections of traditional underwires are rectangular, the cross-section of the polymeric breast support is rounded or otherwise curved to provide better comfort. The dimensions of the cross-section are substantially larger than traditional underwire, providing more surface area and better distribution of breast tissue weight to reduce pressure, pinching, and digging. Further, while the cross-section of an underwire remains uniform and the orientation of the cross-section does not change along the length of the underwire, the cross-section of the polymeric breast support varies (it may get thicker underneath of the breasts to support the weight of the breast tissue while tapering near the sternum and axilla for increased comfort) and the orientation of the cross-section twists to accommodate the natural curvature of the body so that the longer cross-sectional dimension of the polymeric breast support lies flush against the body at all points (near the axilla, down around the bottom of the breast, and up along the sternum) for better pressure distribution and comfort. At each of the ends of the polymeric breast support structure, the member tapers and the side exposed to the skin is contoured so that there is no abrupt endings or edges that could poke the axilla or sternum.
(18) The polymeric breast support structure is made of a polymeric material, such that it is flexible and can conform to the body's natural curves and movements (i.e. bending, slouching, leaning over, etc.), changes in body size and tissue volume (i.e. from weight gain/loss, aging, pregnancy, monthly menstrual cycles, etc.) without poking and pinching, unlike traditional underwires made from rigid metal. The added flexibility afforded from a polymeric material allows the polymeric breast support to accommodate a wider range of bra cup sizes relative to a traditional metal underwire with limited flexibility. To ensure comfort on the body, the polymeric material should have a durometer hardness between 20 A and 95 A on the Shore A hardness scale. This softer, squishier material matches that of the skin itself far better than a hard metal, for a better feel. Further, the polymeric breast support structure is capable of recovering to its original shape after being substantially deformed, which increases the longevity of the garment, as traditional underwires will either break or remain in a deformed state after a significantly strong pressure is applied. Finally, the polymeric breast support should have a modulus of elasticity below 1000 MPa so that it is flexible enough to move with the body as the ribcage moves during breathing or as the person moves around. A traditional underwire has a modulus of elasticity of approximately 200,000 MPa, which makes it very rigid and produces discomfort as the person moves around or breathes.
(19) The polymeric breast support is preferably made of a thermoplastic polyurethane (TPU), which could provide all the mechanical properties described above. In other embodiments, silicone could be used. A thermoplastic, an elastomer, or a thermoplastic elastomer (TPE), such as thermoplastic styrenic block copolymers (TPE-S/TPS), which are thermoplastic elastomer compounds based on styrene-butadiene-styrene or styrene-ethylene-butylene-styrene, could also be used, as long as the mechanical properties are suitable.
(20) The exemplary schematic of the polymeric breast support structure is shown in
(21) The polymeric breast support structure 10 is arranged around a central axis 11 which is perpendicular to the ground when the polymeric breast support structure 10 is worn by a user (not shown) standing vertically. The polymeric breast support structure 10 includes the right breast support 12 and the left breast support 14 circumferentially spaced apart from the right breast support 12 relative to the central axis 11. Accordingly, the polymeric breast support structure 10 is curved circumferentially about the central axis 11 to accommodate the contour of a user's torso.
(22) Every edge of the polymeric breast support structure 10 may be curved to avoid the user experiencing discomfort from sharp edges or points while wearing the bra and/or polymeric breast support structure 10.
(23)
(24) This dimensionality in the z-direction ensures that the breast supports 12, 14 rest comfortably on a user's chest and ribs at the bottom of each breast along the inframammary fold section B. The sternum end A has a greater z-value than the inframammary fold section B and it is closer to the central axis 11 to accommodate for the positioning and curvature of the user's sternum relative to the inframammary fold section B. The axillary end C has a greater z-value than both the inframammary fold section B and the sternum end A in order for the breast supports 12, 14 to extend far enough along the user's side body to capture all of a user's breast tissue, including the side breast tissue. The three-dimensional design in the x, y and z directions ensures a more comfortable, contoured fit compared to the traditional underwire that exists in only the x and y directions.
(25) The 3D dimensionality of the polymeric breast support structure 10 can also be seen in
(26) The polymeric breast support structure 10 is placed within the bra or bra-related garment such that the inframammary fold section B of each of the breast supports 12, 14 corresponds to a position that is directly underneath of each of the bottom of the user's breasts when the garment is worn. If the bra or other bra-related garment has traditional bra cups, the polymeric breast support structure 10 is positioned within the bra or other bra-related garment such that each of the breast supports 12, 14 aligns with each of the bra cups 20, 22 of the garment as shown in
(27) When integrated within the bra or bra-related garment, the polymeric breast support structure 10 provides support, separation, and shaping for the wearer's breasts. Each of the breast supports 12, 14 lift the breast tissue higher on the user's chest (i.e. closer to the direction of the user's head) by exerting a force equal or greater to the weight of the breast and in opposite direction to the downward weight of the breast, such that the breast tissue is supported and lifted. The polymeric breast support structure 10 contains two individual breast supports 12, 14, one for each breast, so that each breast rests within its own cup compartment, separate from the other breast. This creates separation of the user's breast tissue. Separation is a desired look for the user and it enhances comfort by preventing breast tissue from rubbing together. Further, the 3D-dimensionality of the breast supports 12, 14 provide a desired shaping by repositioning the wearer's breast tissue from the outside to the midline of their body (i.e. the breasts are centered inwards and projected forward as opposed to being spread out across the chest). The J or U-shape of the breast supports 12, 14 also contributes to a more rounded look of the breast tissue.
(28) The cross-sections of the breast supports 12, 14 are rounded with no hard edges or sharp corners. The cross-sections may be circular, rounded, semi-circular, ovular, rectangular with rounded corners, trapezoidal with rounded corners, a rounded shape with a flat face, or any shape without hard or rough edges in cross-section. Exemplary cross-sections are shown in
(29) Unlike traditional underwires, the cross-section of the breast supports 12, 14 is not uniform throughout its entire length. For example, the cross-section of the breast supports 12, 14 may widen at the very bottom near the inframammary fold section B where the weight of the breast tissue is greatest. This additional cross-sectional area provides supplementary support to lift and shape the breast tissue.
(30) Similarly, in areas where there is less breast tissue weight to support, the cross-section of the breast supports 12, 14 may be reduced. The cross-sections of the breast supports 12, 14 decrease at the sternum end A and at the axillary end C for added comfort. By gradually decreasing the cross-sectional area of the sternum end A and the axillary end C, the breast supports 12, 14 do not abruptly terminate or include hard corners or sharp edges. Rather, the cross-sections at the sternum end A and the axillary end C gradually taper inwards as the ends are approached to eliminate any sharp edges or corners that might poke a user.
(31) In particular, the cross-section is decreased such that there is a tapering and sloping effect at the sternum end A. The sternum end A has an upper edge 30 which is not parallel to the ground when the polymeric breast support structure 10 is worn by a user (not shown) standing vertically, as this would create a sharp corner with a 90 degree right angle that could poke the user. Instead, as highlighted in
(32)
(33) The orientation of the cross-section changes along the length of the breast supports 12, 14. There is twisting of the breast supports 12, 14 to accommodate the natural curvature of the body, as the side-body is approximately perpendicular to the front chest. By incorporating a twist into the breast supports 12, 14 the longer dimension of the cross-section rests upon the body along the entire length of the breast supports 12, 14. This provides more surface area at each point along the length of the breast supports 12, 14 for better tissue distribution. This twisting also prevents the shorter dimension of the cross-section from laying flush with and digging into the body.
(34) In some embodiments, underneath each of the breast supports 12, 14 there is a sewing ledge D which follows the curvature of the breast supports 12, 14 in the x, y and z spatial directions. The sewing ledge D lies flat against the torso at all points along the length of the sewing ledge D. The width of the sewing ledge D should not exceed 2 millimeters, as it should be sufficiently thin to ensure that the sewing needles of sewing machines do not break when puncturing through the sewing ledge D as shown in
(35) In other embodiments, the sewing ledge D may include an underband panel E.
(36) In other embodiments, the polymeric breast support structure 10 may include a first side support panel 16 (that aligns directly underneath of one of the user's axilla), a second side support panel 18 (that aligns directly underneath of the other of the user's axilla) circumferentially spaced apart from the first side support panel 16 relative to the central axis 11. The side support panels 16, 18 may connect at the axillary end C of the breast supports 12, 14 as shown in
(37) The polymeric breast support structure 10 may be formed as a single, solitary component as shown in
(38) However, in some embodiments, there will not be a central panel G and the sternum end A of the right breast support 12 will not be joined to the sternum end A of the left breast support 14 as shown in
(39) Further, there may be slight modifications to the polymeric breast support structure 10 in order to fit better within various bra styles. The right breast support 12 and the left breast support 14 may be adjusted to accommodate variations in the neckline of the bra.
(40) Exemplary embodiments are disclosed in this description. It will be understood that the present invention incorporates other embodiments that are reasonable equivalents to the embodiments described in this disclosure, as evident to a person of reasonable skill in the art, and that the invention is only limited by the appended claims.
