Abstract
This relates to the provision of latch mechanisms for a dispensing closure of the type having a well formed in the top wall thereof with the well being of a stepped bottom construction and there being a closure member which includes a hinge strap and a cover panel with the cover panel having an outline generally corresponding to that of the well and being divided by a transverse hinge line into a cover element and an opener. when the opener is depressed, the cover element automatically swings to an upstanding position uncovering a dispensing opening or openings. Latch mechanisms are provided to retain the opener within the well and to retain the cover element in an upstanding out-of-the-way dispensing position. This abstract is not to be construed as limiting the claims of the application.
