Gel-Cushioned Support Component Channel for a Brassiere
The present disclosure is of a support component channel for a bra and methods for producing the support component channel and attaching it to a bra. The support component channel comprises a gel tube, an underwire tunnel casing, and a cover fabric. The gel tube provides cushion between the support component and the wearer's chest, thereby providing comfort despite the geometry and materials of the support component. The gel tube, underwire tunnel casing, and cover fabric can be sewn to one another simultaneously to being attached to the bra, prior to being attached to the bra, or can be attached to the bra in stages, according to different methods of production. The methods allow for both sides of the support component channel to be sewn to the bra simultaneously.
The present disclosure relates generally to brassieres. More specifically, the present disclosure relates to support components (such as tunnel casings and underwires) for brassieres.
BACKGROUNDBrassieres (bras) are often uncomfortable for a wearer due to the geometry and materials of components that provide support and shape to the bra, such as a tunnel casing and/or an underwire. Further, bras with underwires are often uncomfortable for a wearer due to the hard and sharp edges of metal or resin underwires. It is therefore desirable to cushion the support components of the bra such that the cushion lies between the support component and the wearer's chest. However, current methods do not allow for easy and efficient manufacturing of a bra that incorporates both a cushion and a support component.
SUMMARYThe present disclosure is of a support component channel for a bra and methods for producing the support component channel and attaching it to a bra. The support component channel comprises a gel tube, an underwire tunnel casing, and a cover fabric. The gel tube provides cushion between the support component and the wearer's chest, thereby providing comfort despite the geometry and materials of the support component. The gel tube, underwire tunnel casing, and cover fabric can be sewn to one another simultaneously to being attached to the bra, prior to being attached to the bra, or can be attached to the bra in stages, according to different methods of production. The methods allow for both side edges of the support component channel to be sewn to the bra simultaneously.
The present disclosure is of a support component channel for a bra. The channel comprises a gel tube having a first side and a second side. An underwire tunnel casing is adjacent the first side of the gel tube and is co-extensive in length with the gel tube. A cover fabric is adjacent the second side of the gel tube and is co-extensive in length with the gel tube. Side edges of the cover fabric are folded over respective side edges of the gel tube to cover the gel tube.
A method of creating a bra having a support component channel is also disclosed. The method comprises providing a gel tube having a first side and a second side. The method further comprises providing an underwire tunnel casing co-extensive in length with the gel tube and placing the tunnel casing adjacent the first side of the gel tube. The method further comprises providing a cover fabric co-extensive in length with the gel tube and placing the cover fabric adjacent the second side of the gel tube. The method further comprises covering the gel tube with side edges of the cover fabric that are folded over respective side edges of the gel tube, and attaching the tunnel casing, gel tube, and cover fabric to the bra cup.
In the present description, certain terms have been used for brevity, clearness and understanding. No unnecessary limitations are to be applied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes only and are intended to be broadly construed. The different configurations and methods described herein may be used alone or in combination with other configurations and methods. Various equivalents, alternatives and modifications are possible within the scope of the appended claims. Each limitation in the appended claims is intended to invoke interpretation under 35 U.S.C. §112, sixth paragraph, only if the terms “means for” or “step for” are explicitly recited in the respective limitation.
In the embodiment shown in
If provided, the outer membrane 26 is made of a material that prevents leakage of the gel cushion 28 material onto the cover fabric 20 and bra cup 10. In the embodiments shown in the Figures, the outer membrane 26 does not add significant bulk or shape to the assembled support component channel 12, but is merely a sleeve that protects the fabric of the bra cup 10 from the gel cushion 28 material. In one embodiment, the outer membrane 26 comprises thermoplastic polyurethane (TPU); however, the outer membrane 26 could also comprise any thermoplastic polymer that is compatible with the material of the gel cushion 28. For example, the outer membrane 26 could comprise polyvinyl chloride (PVC), emulsion polyvinyl chloride (EPVC) or polyurethane (PU). In another embodiment, the gel cushion 28 is made of a material that does not leak, and no outer membrane 26 is needed.

When manufacturing the support component channel 12 of the present disclosure, it is possible to use a twin needle sewing machine. The present inventors have recognized that due to the substantially straight configuration of the tunnel casing 24 and gel tube 22 along their lengths L, as shown in

After the tunnel casing 24 and cover fabric 20 are sewn to the bra cup 10, the gel tube 22 is inserted into a gap 42 (see
The method and apparatus described herein allow the support component channel 12 to be sewn to the bra cup 10 (prior to insertion of an underwire 44) with a twin needle sewing machine, due to the fact that the support component channel 12 is in a soft, malleable form. The support component channel 12 (assembled with or without the gel tube 22) also has a substantially straight configuration along its length L prior to it being sewn to the bra cup 10, which allows it to be sewn to the bra cup 10 with a twin needle sewing machine. Further, creating the gel tube 22 as a component separate from the underwire 44 (if an underwire 44 is used) minimizes the requirement for numerous mold blocks for each size and style of underwire, which are required when an underwire and a cushioning gel are molded together during production. The oval cross-sectional shape of the gel tube's 22 gel cushion 28 also provides comfort to the wearer as it protects the wearer from the hard metal or resin underwire 44 (if an underwire 44 is used), but at the same time, is dimensioned to allow the gel tube 22 to pass through a twin needle sewing machine. If included, the thermoplastic polyurethane (TPU) membrane 26 covers the gel cushion 28 and provides protection from oil leakage onto the finished bra cup 10. The fact that the side edges 32a, 32b of the cover fabric 20 are hidden against the fabric of the bra cup 10, combined with the soft and stretchy material of the cover fabric 20, provides comfort against the wearer's skin.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be inferred therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed. The different configurations and method steps described herein may be used alone or in combination with other configurations and method steps. It is to be expected that various equivalents, alternatives, and modifications are possible within the scope of the appended claims. The claimed methods may be performed in various orders, and should be construed to cover various modifications understood by those having ordinary skill in the art. For example, the components described hereinabove may be assembled to one another in a multitude of combinations, orders, and ways, and the methods claimed herein are meant to cover such equivalent alternatives to the combinations, orders, and methods of assembly of such components.
