Abstract: A container is disclosed for retaining a substance. The container comprises a cylindrical body extending between a bottom aperture and a top aperture. A bottom plate engages the bottom aperture for sealing the bottom aperture of the cylindrical body. A conical flange extends between a first aperture and a second aperture. The first aperture of the conical flange defines a first diameter. The second aperture of the conical flange defines a second diameter. The second diameter of the second aperture has a greater cross-sectional area than the first diameter of the first aperture. The top aperture of the cylindrical body is secured to the first aperture of the conical flange for coupling the cylindrical body to the conical flange. A tubular body extends between a bottom aperture and a top aperture. The bottom aperture of the tubular body is secured to the second aperture of said conical flange for coupling the tubular body with the conical flange.
