Cylindrical vial with bottom for medicine

Abstract

A cylindrical vial having a bottom, for a medicine, in which an open end of the cylindrical vial is sealed by a needle-penetrable rubber closure through which a needle can be penetrated, the cylindrical vial including a conical bottom end provided opposite to the open end, wherein the apex of the conical bottom end is located on a central axis of the cylindrical vial at the bottommost point inside the cylindrical vial.

What is claimed is:  
     
         1 . A cylindrical vial having a bottom, for a medicine, in which an open end of said cylindrical vial is sealed by a needle-penetrable rubber closure through which a needle can be penetrated, said cylindrical vial comprising: 
 a conical bottom end provided opposite to said open end, wherein the apex of said conical bottom end is located on a central axis of said cylindrical vial at the bottommost point inside said cylindrical vial.    
     
     
         2 . The cylindrical vial having a bottom according to  claim 1 , wherein said cylindrical vial is formed using an injection molding die assembly including a core pin, said core pin being in the form of a rod having a uniform diameter and having a conical front end.  
     
     
         3 . The cylindrical vial having a bottom according to  claim 1 , wherein said cylindrical vial is formed using an injection molding die assembly including a core pin, said core pin being in the form of a tapered rod having a conical front end and having an outer diameter gradually increasing from the conical front end toward the other end thereof.  
     
     
         4 . The cylindrical vial having a bottom according to  claim 1 , wherein said conical bottom end of said cylindrical vial defines an angle in the range of 30° through 70° between the generatrix of said conical bottom end and the central axis of said cylindrical vial.  
     
     
         5 . A cylindrical vial for a medicine, comprising an axial hollow portion, an open end connected to said axial hollow portion and a closed end opposite to said open end; 
 wherein said open end is sealed by a needle-penetrable rubber closure through which a needle can be penetrated into said cylindrical vial, and wherein said closed end comprises a conical bottom end, the apex of said conical bottom end being located on a central axis of said axial hollow portion at the bottommost point inside said axial hollow portion.    
     
     
         6 . The cylindrical vial according to  claim 5 , wherein said axial hollow portion is formed using an injection molding die assembly including a core pin, said core pin being in the form of a rod having a uniform diameter and having a conical front end.  
     
     
         7 . The cylindrical vial according to  claim 5 , wherein said axial hollow portion is formed using an injection molding die assembly including a core pin, said core pin being in the form of a tapered rod having a conical front end and having an outer diameter gradually increasing from the conical front end toward the other end thereof.  
     
     
         8 . The cylindrical vial according to  claim 5 , wherein said conical bottom end of said cylindrical vial defines an angle in the range of 30° through 70° between the generatrix of said conical bottom end and the central axis of said axial hollow portion.
