Embodiment Construction

[0022] Unless expressly indicated, directional phrases (such as clockwise, counterclockwise, left, right, top, bottom, up, down, and derivatives thereof) used herein refer to the orientation of elements shown in the drawings, but do not limit rights. Require.

[0023] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

[0024] As used herein, "constructed [verb]" means that an identified element or component has a structure that is shaped, sized, arranged, coupled and / or configured to perform the identified verb. For example, a member "configured to move" is movably coupled to another element and includes an element that causes the member to move, or the member is configured to move in response to other elements or components. Thus, as used herein, "constructed to [verb]" describes structure rather than function. Furthermore, as used herein, "constructed to [verb]" means that the identified element o...

Abstract

A formed blank (10) is provided. The formed blank (10) includes a stretched portion (38) and / or a truncated protrusion (20), a tooling assembly (100) structured to form a formed blank (10) including astretched portion (38) and / or a truncated protrusion (22), and a method of forming (1000) a formed blank (10) including a stretched portion (38) and / or a truncated protrusion (22). The formed blank (10) includes a base (12) and a depending sidewall (14). The stretched portion (38) and / or the truncated protrusion (22) is disposed on the formed blank base (12) and the thickness of the stretched portion (38) and / or the truncated protrusion (22) is less than the sidewall (14). The stretched portion (38) and / or the truncated protrusion (22) utilizes less material relative to an unformed base thathas about the same thickness as the sidewall (14).

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application Serial No. 15 / 382,850, filed December 19, 2016, which is hereby incorporated by reference. technical field [0003] The disclosed concept relates generally to containers, and more particularly to metal containers such as beer or beverage cans and food cans. The disclosed concept also relates to cups and blanks for forming cups and containers. The disclosed concept also relates to methods and tooling for selectively shaping the bottom portion of a cup or container to reduce the amount of material in the cup or bottom portion. Background technique [0004] Drawing and thinning deep-drawn metal slabs is known to produce thin-walled containers or cans for packaging beverages (eg carbonated; non-carbonated), food or other substances. As is known, many such containers have a generally cylindrical shape and it is assumed that the examples discussed herein have thi...
