Abstract
An object of the present invention is to make it possible for the volume of a metal container body to be greatly reduced after the juice or beer contained therein has been consumed and the container is to be disposed of, and thus the number of empty container bodies that can be accommodated in a trash can is much greater than the limited number of the empty conventional container bodies which could be accommodated the trash can. The cylindrical metal container body capable of retaining a state of being reduced in a longitudinal direction is formed such that the outer periphery and the inner periphery thereof are formed with accordion-shaped portions having horizontal ring-shaped hill portions and valley portions.
Claims12
A metal container capable of retaining a state of being reduced in a longitudinal direction, wherein its outer periphery and inner periphery (2) of a container body (1) having a cylindrical shape are formed as accordion-shaped portions (5) including hill portions (3) and valley portions (4) having an annular shape in a horizontal direction.
A metal container capable of retaining a state of being reduced in a longitudinal direction, wherein the entire length or a part of the length in the longitudinal direction of the container body (1), has horizontal or spiral accordion-shaped portions (5), and when a force is applied in a substantially vertical direction with respect to the accordion-shaped portions, a force acting in one direction is exerted on a part of an inner periphery and/or a fold constituting the accordion-shaped portion (5), and an opposing force acts on the outer periphery so that the accordion-shaped portions (5) retain a state in which said accordion-shaped portions (5) are reduced in a longitudinal direction.
A method of reducing a metal container such that the metal container is capable of retaining a state of being reduced in a longitudinal direction, comprising the steps of:
- applying a force in a substantially perpendicular direction with respect to the horizontal or spiral accordion-shaped portions (5) which are along the entire length or along a part of the length in the longitudinal direction of the container body (1);
- and
- applying a force which presses in one direction on a part of an inner periphery and/or a fold constituting the accordion-shaped portion (5), causing an opposing force to act on the outer periphery and so that the accordion-shaped portion (5) retains a state in which said accordion-shaped portions are reduced in the longitudinal direction.
A metal container capable of retaining a state of being reduced in the longitudinal direction, comprising a container body (1) provided with a tap portion which can be caused to jut out in an upward direction from a central portion of said container body (1), and horizontal accordion-shaped portion (5) are formed at inner and outer walls of the container body in the entire a length (height) direction or in a portion of said direction, and the diameter of accordion-shaped portion is smaller at the top of the container body than that at the bottom, and the diameter increases sequentially as the bottom of the container body is approached, and when force is applied in a substantially perpendicular direction with respect to the accordion-shaped portions (5) of the container body (1),
- a force acts downward in the inner diameter direction of the wall of the upper accordion-shaped configurations and upwards in the outer diameter direction, and another force acts downwards in the inner diameter direction of the folds of the upper accordion-shaped configurations so that the accordion-shaped portions retain a state in which the length (height) of the container body (1) is reduced.
