Abstract
In a pop-up device for use in a magazine or other publication or for use by itself such as a mailer or the like, two display elements are hingedly connected to a front of two covers. The opening of the front cover forces the erection of the two display elements and allows the elements to stand up out of the plane thereof. A spacing tab is connected between a foreground display element and the back cover and also is connected between a background display element and the back cover. The spacing tab restrains the displays from following the front panel a full one hundred eighty degrees while allowing them each to raise to a specified distance from the back cover. The pop-up is designed for mass-production mechanical fabrication and assembly. A blank is cut to form the display elements and the spacing tabs and is scored to form lines of weakness, which allow easy folding, in the appropriate places. Adhesive is then applied and, after appropriate plowing, folding and trimming processes, the pop-up device is formed.
