DEFINITION

Classification: 229/125.19

Closure includes a depending flange or tab which extends along an adjacent box wall:

(under subclass 125.01) Subject matter wherein the nonunitary closure includes a downwardly extending element which, when the closure is in its closed position, overlies all or part of a box wall bordering the access opening. [figure] [caption]closure; depending flange

(1) Note. The element may extend either exteriorly or interiorly of the box.

(2) Note. The element may be anything from a relatively small "leg" or "ear" which is attached along only a fraction of the length or width of the closure (i.e., a tab), to a piece of material which is attached along the entire length

or width of the extension and may cover most or all of an adjacent box wall (i.e., a flange).
