Microwavable Metallic Container
The present invention relates to a method for processing, storing and heating foodstuffs in a partially metal microwavable bowl, and more specifically, a substantially metallic stackable container with a microwavable transparent portion and a selectively removable lid, wherein the same container can be used to store, ship, heat, and serve a foodstuff to a consumer.
1 . A method for manufacturing a container with a metallic sidewall which is adapted for use in a microwave oven, comprising:
providing a substantially planar metallic material having an upper edge, a lower edge and sidewalls interconnected thereto;
forming a substantially cylindrical shaped enclosure from said substantially planar metallic material;
interconnecting the sidewalls of the substantially cylindrical shaped enclosure to substantially retain a preferred shape;
providing a bottom portion comprising a microwavable transparent material;
interconnecting said bottom portion to a lower end of said substantially cylindrical shaped enclosure;
providing an end closure; and
interconnecting said end closure to an upper end of said substantially cylindrical shaped enclosure.
2 . The method of claim 1 , wherein said substantially planar metallic material comprises at least one of a tin, a steel and an aluminum material.
3 . The method of claim 1 , wherein said end closure is double seamed to an upper end of said sidewalls.
4 . The method of claim 1 , wherein said substantially cylindrical shaped enclosure has an upper portion with a diameter which is greater than a lower portion.
5 . The method of claim 1 , wherein said bottom portion is double seamed to said lower end of said substantially cylindrical shaped enclosure.
6 . The method of claim 1 , wherein said microwavable transparent material comprises at least one of polypropylene, a polyethylene and an EVOH material.
7 . The method of claim 1 , further comprising positioning a removable lid on said end closure, said lid having at least one aperture to release heat from said container during the heating of a foodstuff in the microwave oven.
8 . The method of claim 1 , further comprising the step of interconnecting an insulative material over at least a portion of an exterior surface of said sidewalls.
9 . The method of claim 1 , wherein said end closure further comprises a pull tab, wherein at least a portion of said end closure is selectively removable.
10 . The method of claim 1 , wherein substantially the entire bottom portion is comprised of a microwave transparent material.
11 . The method of claim 1 , further providing a tamper resistant indicator in at least one of said substantially cylindrical shaped enclosure and said end closure which identifies a change of internal pressure in said container.
