One of the edge concealments on bra cup technology

Abstract

The present disclosure relates to the technical field of underwear. A bra cup and a bra are disclosed. The bra cup has an outer cover layer and a filling layer, where the filling layer is arranged on a side of the outer cover layer located on an arc-shaped concave surface. Compared with bra cups which are laminated by a fabric and a lining, a lining of the bra cup provided by the present disclosure is removed. Since the filling layer is only distributed in parts that need to be supported, the thickness of an outer edge of the cup is reduced to avoid the stiffness of the outer edge, thereby improving the breathability.

What is claimed is: 
     
         1 . A bra cup, comprising:
 an outer cover layer having an arc-shaped concave surface; and   a filling layer arranged on the outer cover layer and located on the arc-shaped concave surface.   
     
     
         2 . The bra cup according to  claim 1 , further comprising:
 an inner cover layer, wherein the inner cover layer is located at a side of the outer cover layer where the arc-shaped concave surface is located, and an outer edge of the inner cover layer is connected to the outer cover layer; the outer edge of the inner cover layer partially overlaps with the outer edge of the outer cover layer; and the filling layer is located between the inner cover layer and the outer cover layer.   
     
     
         3 . The bra cup according to  claim 2 , wherein the inner cover layer has a single-layer structure or a multi-layer structure. 
     
     
         4 . The bra cup according to  claim 1 , wherein the filling layer is located at at least one of a bottom end, a top end or a side end of the arc-shaped concave surface. 
     
     
         5 . The bra cup according to  claim 2 , further comprising:
 a middle layer, wherein the middle layer is located between the filling layer and the outer cover layer; and an outer edge of the filling layer does not extend beyond an outer edge of the middle layer.   
     
     
         6 . The bra cup according to  claim 5 , wherein the outer cover layer and the middle layer, the middle layer and the filling layer, and the filling layer and the inner cover layer are all bonded with a hot melt adhesive. 
     
     
         7 . The bra cup according to  claim 2 , wherein the outer cover layer and the filling layer, and the filling layer and the inner cover layer are both bonded with a hot melt adhesive. 
     
     
         8 . The bra cup according to  claim 1 , wherein the filling layer is one of:
 a polyurethane foam, an air bag, an oil bag, a spacer fabric, a silicone product, a fiberfill, a fabric, or thermoplastic.   
     
     
         9 . The bra cup according to  claim 1 , wherein the bra cup comprises at least one of the filling layers. 
     
     
         10 . The bra cup according to  claim 3 , further comprising:
 a middle layer, wherein the middle layer is located between the filling layer and the outer cover layer; and an outer edge of the filling layer does not extend beyond an outer edge of the middle layer.   
     
     
         11 . The bra cup according to  claim 3 , wherein the outer cover layer and the filling layer, and the filling layer and the inner cover layer are both bonded with a hot melt adhesive. 
     
     
         12 . A bra, comprising a pair of bra cups, wherein each of the pair of bra cups comprises:
 an outer cover layer having an arc-shaped concave surface; and   a filling layer arranged on the outer cover layer and located on the arc-shaped concave surface.   
     
     
         13 . The bra according to  claim 12 , wherein the bra cup further comprises:
 an inner cover layer, wherein the inner cover layer is located at a side of the outer cover layer where the arc-shaped concave surface is located, and an outer edge of the inner cover layer is connected to the outer cover layer; the outer edge of the inner cover layer partially overlaps with the outer edge of the outer cover layer; and the filling layer is located between the inner cover layer and the outer cover layer.   
     
     
         14 . The bra according to  claim 13 , wherein the inner cover layer has a single-layer structure or a multi-layer structure. 
     
     
         15 . The bra according to  claim 12 , wherein the filling layer is located at at least one of a bottom end, a top end or a side end of the arc-shaped concave surface. 
     
     
         16 . The bra according to  claim 13 , further comprising:
 a middle layer, wherein the middle layer is located between the filling layer and the outer cover layer; and an outer edge of the filling layer does not extend beyond an outer edge of the middle layer.   
     
     
         17 . The bra according to  claim 16 , wherein the outer cover layer and the middle layer, the middle layer and the filling layer, and the filling layer and the inner cover layer are all bonded with a hot melt adhesive. 
     
     
         18 . The bra according to  claim 13 , wherein the outer cover layer and the filling layer, and the filling layer and the inner cover layer are both bonded with a hot melt adhesive. 
     
     
         19 . The bra according to  claim 12 , wherein the filling layer is one of:
 a polyurethane foam, an air bag, an oil bag, a spacer fabric, a silicone product, a fiberfill, a fabric, or thermoplastic.   
     
     
         20 . The bra according to  claim 12 , wherein the bra cup comprises at least one of the filling layers.
