Abstract: A reversible envelope is disclosed that has a front face, a rear face, two side tabs and a flap member with a removable cover. The arrangement of the various members is such that upon the construction of the first-use envelope, there will be no members within the envelope container that could hinder stuffing of the envelope. In addition, the construction of the envelope is such that there will be a minimum usage of paper and production steps to create the blank that is folded into the envelope. The reversible envelope of the invention is simple to use and can be explained with directions that are easy to follow.

Abstract: A dynamic eave building system comprising a flexible joint for first vertical and second angulated structural members pivotally connected one to the other. The adjacent ends of the first and second structural members are mitered into a mating configuration and spaced one from the other by the pivot joint. The pivot joint comprises a pivot pin received through aligned apertures formed in one of the members and in a knee splice secured in the other. The knee splice is positioned to define the flexing space between the mitered ends. The second angulated member also includes moisture collection troughs formed longitudinally therealong. The first member is provided in a hollow configuration for receiving fluid flow from the troughs of the second angulated member. Both members are adapted for securement of conventional curtain wall material, siding or roofing thereon.
