Support Structure of Bra Cup

Abstract

A support structure of a bra cup contains: a body and a reinforcement underwire. The body includes at least one connection layer, a concave face, and a convex face. The reinforcement underwire is in an arcuate strap shape and is fixed on a bottom of the body, and the reinforcement underwire includes at least one core layer and a protection layer, wherein the at least one core layer is made of fabric material, and the protection layer is made of thermoplastic material and covers the at least one core layer. Thereby, the reinforcement underwire has flexibility and support capacity, and the body is fixed on a brassiere so as to enhance wearing comfort of the brassiere.

What is claimed is: 
     
         1 . A support structure of a bra cup comprising:
 a body including at least one connection layer, a concave face, and a convex face; and   a reinforcement underwire being in an arcuate strap shape and being fixed on a bottom of the body, the reinforcement underwire including at least one core layer and a protection layer, wherein the at least one core layer is made of fabric material, and the protection layer is made of thermoplastic material and covers the at least one core layer.   
     
     
         2 . The support structure of the bra cup as claimed in  claim 1 , wherein the body includes an internal connection layer, an external connection layer, the reinforcement underwire is fixed between a bottom of the internal connection layer and a bottom of the external connection layer of the body. 
     
     
         3 . The support structure of the bra cup as claimed in  claim 2 , wherein the internal connection layer is comprised of a first substrate and a lining fabric adhered on an inner surface of the first substrate, and the external connection layer is comprised of a second substrate and a covering fabric adhered on an outer surface of the second substrate, wherein the first substrate and the second substrate are made of foam or cotton fibers. 
     
     
         4 . The support structure of the bra cup as claimed in  claim 1 , wherein the reinforcement underwire includes a first core layer, a second core layer, and a protection layer, wherein the second core layer covers the first core layer, and the protection layer covers the second core layer. 
     
     
         5 . The support structure of the bra cup as claimed in  claim 4 , wherein the first core layer has a hollow portion defined therein. 
     
     
         6 . The support structure of the bra cup as claimed in  claim 1 , wherein the reinforcement underwire is fixed on a bottom of the concave face of the body. 
     
     
         7 . The support structure of the bra cup as claimed in  claim 1 , wherein the connection layer is comprised of a substrate, a lining fabric adhered on an inner surface of the substrate, and a covering fabric adhered on an outer surface of the substrate, wherein the substrate is made of foam or cotton fibers.
