A metal container with thread capable of preventing such a defect that the strength of a lower end of a mouth part and an upper end of a shoulder part of a container main body is non-resistant to a pressing force in radial and axial directions, and a part of the container may be collapsed or buckled
A metal container with thread capable of preventing such a defect that the strength of a lower end of a mouth part and an upper end of a shoulder part of a container main body is non-resistant to a pressing force in radial and axial directions, and a part of the container may be collapsed or buckled during a capping operation where content is filled into the container and cap is fitted to the container automatically by a machine, characterized in that at least one or more inwardly curving smooth annular recessed parts(4) and at least one or more outwardly curving smooth annular projected parts(5) are formed in an area ranging from the lower end (2a) of the mouth part(2) of the container main body to around the upper end(3a) of a tapered shoulder part increasing gradually in radial direction.

1. A metal container with thread manufactured by drawing, drawing-and-ironing or impact forming from a metallic material, having a container main body consisting of a mouth part with a threaded part, a tapered shoulder part, a trunk part and a bottom part and maintaining a highly airtight condition with a cap screwed on,characterized in that only one inwardly curving smooth annular recessed part is formed around an upper end of said smooth tapered shoulder part widening in a radial direction toward below from a lower end of said mouth part,wherein a bead part for bending a lower end of said cap for engagement is formed in the vicinity of said lower end of said mouth part, the bead part being an annular groove having an almost trapezoidal cross-sectional configuration, andwherein the inwardly curving smooth annular recessed part has a tangent line at its lowest end at an angle of inclination relative to a perpendicular reference line of approximately 35 to 60 degrees.2. A metal container with thread manufactured by drawing, drawing-and-ironing or impact forming from a metallic material, having a container main body consisting of a mouth part with a threaded part, a tapered shoulder part, a trunk part and a bottom part and maintaining a highly airtight condition with a cap screwed on,characterized in that only one inwardly curving smooth annular recessed part and only one outwardly curving smooth annular protruded part are formed around an upper end of said smooth tapered shoulder part widening in a radial direction toward below from a lower end of said mouth part,wherein a bead part for bending a lower end of said cap for engagement is formed in the vicinity of said lower end of said mouth part, the bead part being an annular groove having an almost trapezoidal cross-sectional configuration, andwherein the inwardly curving smooth annular recessed part and the outwardly curving smooth annular protruded part has a common tangent line at an angle of inclination relative to a perpendicular reference line of approximately 35 to 60 degrees.3. A metal container with thread manufactured by drawing, drawing-and-ironing or impact forming from a metallic material, having a container main body consisting of a mouth part with a threaded part, a tapered shoulder part, a trunk part and a bottom part and maintaining a highly airtight condition with a cap screwed on,characterized in that only one inwardly curving smooth annular recessed part is formed around an upper end of said smooth tapered shoulder part widening in a radial direction toward below from a lower end of said mouth part,wherein a bead part for bending a lower end of said cap for engagement is formed in the vicinity of said lower end of said mouth part, the bead part being an annular groove having an almost trapezoidal cross-sectional configuration, andwherein the inwardly curving smooth annular recessed part has a radius of curvature in a range of approximately 0.5 mm to 5.0 mm and a tangent line at its lowest end at an angle of inclination relative to a perpendicular reference line of approximately 35 to 60 degrees.4. A metal container with thread manufactured by drawing, drawing-and-ironing or impact forming from a metallic material, having a container main body consisting of a mouth part with a threaded part, a tapered shoulder part, a trunk part and a bottom part and maintaining a highly airtight condition with a cap screwed on,characterized in that only one inwardly curving smooth annular recessed part and only one outwardly curving smooth annular protruded part is formed around an upper end of said smooth tapered shoulder part widening in a radial direction toward below from a lower end of said mouth part,wherein a bead part for bending a lower end of said cap for engagement is formed in the vicinity of said lower end of said mouth part, the bead part being an annular groove having an almost trapezoidal cross-sectional configuration, andwherein the inwardly curving smooth annular recessed part and the outwardly curving smooth annular protruded part has a radius of curvature in a range of approximately 0.5 mm to 5.0 mm and a common tangent line at an angle of inclination relative to a perpendicular reference line of approximately 35 to 60 degrees.5. A metal container with thread manufactured by drawing, drawing-and-ironing or impact forming from a metallic material, having a container main body consisting of a mouth part with a threaded part, a tapered shoulder part, a trunk part and a bottom part and maintaining a highly airtight condition with a cap screwed on,characterized in that only one inwardly curving smooth annular recessed part or only one inwardly curving smooth annular recessed part and only one outwardly curving smooth annular protruded part is formed around an upper end of said smooth tapered shoulder part widening in a radial direction toward below from a lower end of said mouth part,wherein a bead part for bending a lower end of said cap for engagement is formed in the vicinity of said lower end of said mouth part, the bead part being an annular groove having an almost trapezoidal cross-sectional configuration, andwherein said shoulder part being oriented at an angle with respect to a perpendicular line in a range of approximately 25 to 30 degrees, and the inwardly curving smooth annular recessed parts and/or the outwardly curving smooth annular protruded part has a radius of curvature as viewed in cross-section in a range of approximately 0.5 mm to 5.0 mm.
