Feed out container

A feed out container comprising:

• a metal main body outer sleeve formed as a cylinder with a bottom;
• a metal cylindrical inner member having a first portion provided within an interior of the main body outer sleeve and a second portion that extends outward from an open end of the main body outer sleeve, at least a portion of the first portion being in close contact with the main body outer sleeve throughout the entire circumference thereof and the second portion constituting an annular protrusion adjacent to the open end of the main body outer sleeve;
• an inner plate that holds a solid contained material and is provided within the interior of the main body outer sleeve so as to be movable in an axial direction of the sleeve;
• a metal lid body outer sleeve formed as a cylinder with a bottom, that defines a closed interior space with the main body outer sleeve by an end surface at an open end thereof abutting the protrusion;
• a lid body inner sleeve provided within the interior of the lid body outer sleeve, of which at least a portion is in close contact with the lid body outer sleeve throughout the entire circumference thereof;
• a feed out mechanism that moves the inner plate in an axial direction of the sleeve to feed out the contained material from the inner member;
• and
• a first O ring fitted about a periphery of a portion of the inner member more toward a distal end thereof than the protrusion that maintains an airtight seal between the lid body outer sleeve and the inner member when the lid body outer sleeve is provided at a lid closed position, at which the lid body outer cylinder defines the closed interior space, and optionally a second O ring fitted about the periphery of a portion of the inner member more toward a rear end than the protrusion to maintain an airtight seal between the inner member and the main body outer sleeve;
• the lid body inner sleeve being formed by a polyester series elastomer.
