The present disclosure relates to a bra having support portions. Specifically, the present disclosure relates to a bra having one or more flexible elastomeric support strips located on either an outer-facing or an inner-facing surface of a breast cup.
Conventional bras may provide support through the use of underwires made of metals or hard plastics. Providing support by using underwires has a number of drawbacks. For instance, they can cause discomfort by pressing uncomfortably into the wearer's flesh. In addition, because typical underwires are made of metal or hard plastic, they are generally affixed to the bra by encasing the underwire between layers of bra material. The user of multiple layers of bra material not only adds to manufacturing costs and waste but also adds bulk and weight to the bra. Furthermore, the tip of the underwire may penetrate one or more of the layers and cause chaffing or other discomfort to the wearer. Traditional underwires, moreover, fail to flex and bend with the wearer again causing discomfort and limiting the wearer's range of movement.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The present invention is defined by the claims.
At a high level, aspects herein are directed towards a bra that provides support through the use of flexible elastomeric support strips that are bonded or affixed to an inner-facing surface and/or an outer-facing surface of a breast cup. The elastomeric support strips may be positioned towards a lower margin of the breast cup such that they provide support to the under portion of a wearer's breasts when the bra is worn. The support strips, moreover, may be configured to extend or curve upward in a lateral and/or medial direction such that the strips may also provide support to the lateral and medial sides of the wearer's breasts when the bra is worn. In another example, the support strips may be positioned along the shoulder strap area of the bra to help limit stretch in this area and to provide support to the wearer's breasts.
In an exemplary aspect, the breast cups of the bra may be formed of a single layer of material and the elastomeric supports strips may be positioned on an outer-facing surface of the breast cup such that the strips are exposed to an external environment when the bra is in an as-worn configuration, or the support strips may be positioned on an inner-facing surface of the breast cup such that they lie adjacent to the wearer's skin. In other words, the elastomeric support strips are not sandwiched between different layers of the bra material and/or covered by another layer of bra material. By not sandwiching the support strips between different layers of bra material, the number of layers used to construct the bra may be reduced down to, for example, the single layer described herein which decreases the weight and/or bulk of the bra. This may be advantageous from an athletic performance perspective.
In another exemplary aspect, the breast cup may comprise one or more layers of material, and the elastomeric support strips may be positioned on the outer-facing surface of the breast cup such that at least a portion of the strips are exposed to the external environment. In other words, at least a portion of the elastomeric strips may not be sandwiched between different layers of the bra material and/or covered by another layer(s) of bra material.
In yet another exemplary aspect, the breast cup may comprise one or more layers of material, and at least a portion of the elastomeric support strips may be positioned on the inner-facing surface of the breast cup such that they are directly adjacent to the wearer's skin when the bra is being worn. To put it another way, at least a portion of the elastomeric support strips in this aspect are not sandwiched between layers of bra material and/or covered by a layer(s) of bra material.
Continuing, in another exemplary aspect, the breast cup may comprise one or more layers of material and a first elastomeric support strip(s) may be positioned on the outer-facing surface of the breast cup and a second elastomeric support strip(s) may be positioned on the inner-facing surface of the breast cup. This configuration may provide an additional layer of support.
By positioning the elastomeric support strips on the outer-facing surface of the breast cup such that they are exposed, advantages may be obtained. For instance, the strips may interact in some way with an outer shirt material. As an example, the elastomeric strip(s) may have a surface texture and/or a property such as stickiness that may help to keep the outer shirt material from shifting or riding-up during movement. As another example, the support strip(s) may be colored such that it adds aesthetic appeal to the bra and/or the outer shirt material/bra combination. Moreover, the coloring may indicate a particular level of support provided by the bra and thereby make a consumer's shopping experience easier and less time-consuming.
When positioned on the inner-facing surface of the breast cup such that the strips are positioned next to a wearer's skin surface, properties of the elastomeric strips such as surface texture and/or stickiness may cause the strips to slightly adhere to the wearer's skin thereby helping to keep the bra from shifting during movement.
Examples of the present invention are described in detail below with reference to the attached drawing figures, wherein:
The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” might be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly stated.
Aspects herein relate to a bra having one or more support portions. The support portions may comprise flexible elastomeric support strips that are affixed to an outer-facing surface and/or an inner-facing surface of the breast cups. To provide support to, for example, the under portions and/or the lateral/medial portions of a wearer's breasts when the bra is worn, the strips may be located on the breast cups such that they extend generally from a lateral side of the breast cup, down towards a lower margin of the breast cup, and up to a medial side of the breast cup such that the support strips may have a curved or arched shape. The strips may also be located on the shoulder portions of the bra to help limit stretch in this area and thus provide support to the wearer's breasts.
The elastomeric support strips may be configured to provide support in a number of different ways. For instance, the support strips may comprise a material that has a high modulus of elasticity such as, for example, thermoplastic polyurethane materials. Modulus of elasticity may be defined as a measure of an object's resistance to being deformed elastically when a force is applied to it. Modulus values, as described herein, are measured at 40% stretch across the width of the bra by ASTM D4964 and are expressed in pound-force (lbf) or Newton (N). By applying the strips to the bra material, stretch may be reduced in the areas of application due to the high modulus values of the strips (e.g., the strips resist stretch). Moreover, the hardness of the strips may be modified to increase or decrease the modulus of elasticity of the support strips. For instance, increasing the hardness would increase the modulus of elasticity and decreasing the hardness would decrease the modulus of elasticity. In an exemplary aspect, the hardness of the strips may have a range from 40 Shore A up to 95 Shore A.
Support may also be provided by decreasing the elasticity of the breast cup material on which the support strips overlay. For example, when formed from thermoplastic polyurethane, the support strips may exhibit the property of melting, or partially melting when heated and returning to a solid state when sufficiently cooled. Thus, a thermal bonding process may be used to form a thermal bond between the support strips and the material that forms the bra. Thermal bonding may involve melting or softening the support strips such that the thermoplastic polymer intermingles with the material(s) forming the breast cups. For example, the melting or softening of the thermoplastic polymer may cause the polymer material to extend around or bond with filaments or fibers of yarns that make up the material forming the breast cups. This, in turn, may restrict the movement or stretch of the yarns which limits the overall stretch in the areas to which the support strips are applied. By limiting stretch in these areas, support may be achieved.
The elastomeric support strips may also provide mechanical support to the wearer's breast tissue due to, for instance, the shape configuration of the strips. For instance, the elastomeric support strips may be configured to have different widths and/or thicknesses along their length to provide varying degrees of support, where areas having a greater width and/or thickness may provide a higher level of mechanical support to the wearer's breasts. Any and all such aspects, and any variation thereof, are contemplated as being within the scope herein.
In exemplary aspects, the bra is configured such that at least a portion of the elastomeric support strips are left exposed. In other words, at least a portion of the elastomeric strips are not sandwiched between layers of bra material nor are they covered in any way by bra material. The elastomeric support strips may have, in exemplary aspects, a property (either inherent or applied thereto) such as stickiness and/or a surface texture such as flocking that interact in some way with either an outer shirt material and/or the wearer's skin when the bra is worn. The interaction between the support strips and the outer shirt material may, in aspects, help to keep (i.e., reduce the likelihood) the outer shirt material from shifting or “riding up” during movement. And likewise, the interaction between the strips and the wearer's skin may help to keep the bra from shifting during movement. In another exemplary aspect, the support strips may have a color different from that of the bra to add aesthetic appeal to the bra and/or to act as a visual indicator of, for instance, the level of support provided by the bra.
As described above, the elastomeric support strips may comprise a polyurethane or thermoplastic polyurethane material, a silicone material, a foam material, and the like. One exemplary polyurethane material is produced by Taiwan Kurim Enterprises located in Taichung, Taiwan. In other exemplary aspects, the support strips may be formed of a seam tape, a fabric material, a plastic material, a rubber material, a metal material, and the like. Any and all aspects, and any variation thereof, are contemplated as being within the scope herein. The elastomeric support strips may be attached or affixed to the bra using, for instance, a thermal bonding process, a heat-activated adhesive, stitching, and the like. The elastomeric support strips are configured to have high-abrasion resistance, a soft feel, high UV resistance, as well as a high degree of resistance to degradation due to high or low temperatures.
Turning now to
Terms used throughout this disclosure such as anterior, posterior, superior, inferior, medial, and lateral are meant to have their common meaning with respect to the bra being worn by a wearer standing in anatomical position.
The material used to form the bra 100 or portions thereof, may comprise knitted or woven materials that exhibit a degree of stretch so as to allow the bra 100 to be easily donned and doffed by, for instance, pulling the bra 100 over the wearer's head. For instance, the material may exhibit between 7 N to 8 N at 40% stretch using standard modulus of elasticity tests. In exemplary aspects, the material may exhibit moisture-management characteristics (i.e., the ability of a fabric to transport moisture from a first surface of the fabric to a second surface of the fabric). In exemplary aspects, the material may comprise 80% polyester/20% spandex, 85% polyester/15% spandex, 88% polyester/12% spandex, 90% polyester/10% spandex, or materials having ratios of polyester and spandex between these values or above and below these values.
The bra 100 comprises at least a front portion or region 110, breast cups 112, shoulder straps 114, support strips 116, a back portion or region (not shown in
As mentioned, the front region 110 of the bra 100 is the portion of the bra 100 that covers a portion of the torso of the wearer including the wearer's breasts. The front region 110 may include the pair of breast cups 112 which, in some aspects, may be unstructured or may be structured or constructed such that they conform generally to the shape of the wearer's breasts (e.g., by molding the pair of breast cups). In aspects, the breast cups 112 may be formed from one or more layers of material. By way of example, the breast cups 112 may comprise an inner liner layer or inner-facing layer that comes in contact with the wearer's skin when the bra 100 is worn, and an external shell layer or outer-facing layer that is on the exterior of the bra 100 when the bra 100 is worn. The breast cups 112 may optionally comprise one or more middle layers sandwiched between the inner liner layer and the external shell layer. In another exemplary aspect, the breast cups 112 may comprise a single layer of material having an outer-facing surface that faces the external environment when the bra 100 is worn and an inner-facing surface that faces the wearer's skin when the bra 100 is worn. Any and all aspects, and any variation thereof, are contemplated as being within aspects herein.
The support strips 116 may comprise flexible elastomeric support strips that are affixed on the outer-facing surface of the breast cups 112. As used throughout this disclosure, the term “flexible” implies that the strips can deform or flex in an x-direction, a y-direction, and a z-direction in response to a tensioning force and return to a resting state when the tensioning force is removed. As shown in
The support strips 116 are shown as having a uniform width in
In another example, the first and/or second ends 120 and/or 122 of the strips 116 may be wider to reduce lateral-to-medial swaying of the wearer's breast when the bra 100 is worn. These aspects are illustrated in

Turning back to
Additionally, the support strips 116 may have different thicknesses along their length. Exemplary thicknesses may comprise between 2 mm and 10 mm although values above and below these are contemplated herein. For instance, the support strips 116 may be thicker in areas adapted to provide greater support. In a first example, the support strips 116 may be thicker along the intervening portion 124 of the strips 116 to provide greater support to the under portions of the wearer's breasts when the bra 100 is worn. In a second example, the support strips 116 may be thicker towards the first and/or second ends 120 and/or 122 of the strips 116 to provide greater support to the medial and/or lateral portions of the wearer's breasts when the bra 100 is worn.
This aspect is illustrated in
With respect to
Returning now to
The bra 1000 comprises a plurality of elastomeric support strips. For instance, the bra 1000 may comprises a first set of elastomeric support strips 1020 that generally extend from a medial edge of the shoulder straps 1014 to lateral sides of the bra 1000. The bra 1000 may further comprise a second set of elastomeric support strips 1022 that generally extend from a first lateral side of the bra 1000 to the opposing lateral side of the bra 1000. The elastomeric support strips 1022 are generally configured to curve towards the bottom margin of the bra 1000 such that they curve under the wearer's breasts when the bra 1000 is worn. In exemplary aspects, and as shown in
In exemplary aspects, the first set of support strips 1020 may help to provide support to the shoulder straps 1014 of the bra 1000. As explained above, the support strips 1020 may provide support by virtue of having a high modulus of elasticity and/or by limiting stretch in the areas over which they overlay (via, for instance, forming a thermal bond with the material forming the shoulder straps 1014). In exemplary aspects, stretch in the areas where the support strips 1020 are positioned may exhibit zero or nearly zero stretch at 40% stretch. By using multiple support strips 1020, stretch may be reduced to a greater degree than by using, for instance, a single support strip. The support strips 1020 in exemplary aspects, may comprise varying widths, thicknesses, and/or degrees of hardness. Moreover, in some exemplary aspects, a portion of the support strips 1020 may be overlaid by one or more layers of bra material.
Continuing, in exemplary aspects, the second set of support strips 1022 may help to provide support to the medial, lateral and under portions of the wearer's breasts by, for instance, limiting stretch in the areas over which the strips 1022 overlay and/or by providing structural support based on the thickness, width, and/or hardness of the support strips 1022. In exemplary aspects, stretch in the areas where the support strips 1020 are positioned may exhibit zero or nearly zero stretch at 40% stretch. Similar to above, by using multiple support strips 1022, a greater degree of support may be provided as opposed to using, for instance, a single support strip. The support strips 1022 in exemplary aspects, may comprise varying widths, thicknesses, and/or degrees of hardness. Moreover, in some exemplary aspects, a portion of the support strips 1022 may be overlaid by one or more layers of bra material.
Reference numeral 1024 indicates an area where the first set of support strips 1020 intersect with the second set of support strips 1022. The right side of the bra 1000 would have a similar intersection area (not seen in whole because of the perspective view of
The configuration shown in
Similar to the elastomeric support strips 116 of
In exemplary aspects, the support strips described herein, such as the support strips 116, 316, 416, 600, 700, 800, 1020, 1022, 1100, 1200, and/or 1300 may possess an intrinsic property or be modified or treated such that the exposed surface of the strips exhibit a surface roughness, texture, and/or stickiness that enables the strips to interact in some way with an outer layer of clothing (when the strips are positioned on an outer-facing surface of the breast cups) and/or with a wearer's skin surface (when the strips are positioned on an inner-facing surface of the breast cups). For instance, flocking may be applied to the strip surface to impart a slight roughness to the strip surface. When positioned adjacent to an outer layer of clothing, the support strips may help to reduce the likelihood of the outer layer from “riding up” or substantially shifting during activity. When positioned adjacent to a skin surface of the wearer, the support strips may help to reduce the likelihood of the bra from shifting during activity.
At a step 912, one or more polyurethane strips are affixed to one of the outer-facing surface of the breast cup, the inner-facing surface of the breast cup, and/or to both the outer-facing surface and the inner-facing surface of the breast cup. Affixing may comprise thermal bonding, mechanical bonding, chemical bonding, using a heat-activated adhesive, stitching, and the like. In one exemplary aspect, a liquid form of the polyurethane material may be placed in a mold, and the bra material is positioned on top of the polyurethane. Once positioned, the polyurethane is affixed to the material by using one or more of pressure, heat, ultraviolet light, and the like. As described above, the polyurethane strip may be bonded to the medial, lateral, and lower margins of the breast cup as well as at the upper margins of the breast cup. The breast cup may then be incorporated into a bra.
Additional ways of making a breast cup having support portions are contemplated herein. For instance, one or more layers of material of the breast cup are prepared similar to step 910 of the method 900. The support portions may then be formed at the lower margins of the breast cups by using a screen printing process to gradually build different layers of elastomeric material. Moreover, the screen printing process may be adapted to generate different thicknesses and/or widths of the support strips to provide customized support.
Aspects of the present invention have been described with the intent to be illustrative rather than restrictive. Alternative aspects will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims. Not all steps listed in the various figures need be carried out in the specific order described.
