How unselected shapes are removed from the view

Hi.

    After I add a model to the view. What to do if you want to remove from view again？Suppose my model is added to the view as follows，

TopoDS_Shape aBox;
aBox=BRepPrimAPI_MakeBox(50,70,30).Shape();
Handle(AIS_Shape) AISBox=new AIS_Shape(aBox);
AISBottle->SetMaterial(AISBox,Graphic3d_NOM_GOLD,Standard_True);
mContext->SetDisplayMode(AISBox,1,Standard_False);
mContext->Display(AISBox, Standard_False);

Now I want to delete the Box from the view, but it is not selected, what should I do?I have tried to use the Remove function but it doesn't work。

mContext->Remove(AISBox,Standard_True);
