The invention is related to bra cup support structure, and more particularly, to an improved three-dimension bra cup support structure.
Devices or elements provided to support and shape the lower periphery of the bra cups have long been known in the art. Such devices or elements have come to be commonly known as “underwires”. Over the past years, the underwires have taken many shapes and have been made of many different materials. Commonly, the underwires have been inserted into a fabric sleeves disposed at the lower periphery of the bra cups. U.S. Pat. No. 5,472,366 describes a flexible bra cup support that takes the form of an arcuate length of polymeric or similar materials having a circular cross-sectional shape to fit within the undercup sleeves. The patent to Werner, U.S. Pat. No. 6,106,363 describes a brassiere with helical underwire that is formed by a length of generally helical coil spring.
There are some certain disadvantages that result from usage of the prior underwires have achieved widespread. In particular, the metal-made underwires are rigid and do not have cushioning tips, and might hurt the user's skin producing substantial discomfort. The present invention provides an improved underwire to improve a user's comfort.
Accordingly, the main objective is to provide a three-dimension bra cup support structure, utilized to replace the underwire used in conventional bras. Furthermore, the present invention provides an improved bra cup support structure commonly disposed at the lower periphery of a bra cup to facilitate shaping and to support of the breast of a user.
The three-dimension bra support structure comprises at least two fabric layers, at least two nonwoven layers, and at least one foam layer. The fabric layers are adapted as the surface layer and include an inner fabric layer and an outer fabric layer, also, the nonwoven layers are divided into an inner nonwoven layer and an outer nonwoven layer. Besides, the nonwoven layer is sandwiched in between the fabric layer and the foam layer, and the foam layer is sandwiched in the inner and outer nonwoven layers as the central layer, wherein the foam layer includes a chest end and an underarm end. The chest end is thinner than the underarm end, throughout the thermal-pressing, the chest end is getting flexible and the underarm end getting rigid. Thus, the support structure is utilized to close tightly to a user's chest and to centralize the breast effectively.
Furthermore, the support structure, which has a cross-section shaped as a semi-curve, is divided into an upper edge and a lower edge, wherein the lower edge is subsidiary to the lower periphery of the breast and the upper edge is used for supporting. Moreover, the support structure is formed as one-pieced U-shaped structure or one-pieced double U-shaped structure to be fixed at one or both periphery of the bra cup.
The foregoing aspects, as well as many of the attendant advantages and features of this invention will become more apparent by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
The support structure (1), which has a cross-section shaped as a semi-curve, is divided into an upper edge (11) and a lower edge (12), wherein the lower edge (12) is subsidiary to the lower periphery of the breast and the upper edge (11) is used for supporting. Furthermore, the foam layer (21) has a chest end (13) and an underarm end (14), wherein the chest end (13) is thinner than the underarm end (14). Consequently, throughout thermal-pressing, the chest end (13) is getting flexible and the underarm end (14) getting rigid. Thus, the support structure is utilized to close tightly to a user's chest and to centralize the breast effectively.
Subsequently,
While the invention has been particularly shown and described with reference to the preferred embodiments thereof, these are, of course, merely examples to help clarify the invention and are not intended to limit the invention. It will be understood by those skilled in the art that various changes, modifications, and alterations in form and details may be made therein without departing from the spirit and scope of the invention, as set forth in the following claims.
