  • Patent number: 4112556
    Abstract: A dual zipper construction provides a double closure to discourage opening of the zippered enclosure. The zippers co-extend, one above the other, with the upper zipper closing in a direction opposite that of the lower zipper. Each zipper has its engaging surface mounted on a pair of flaps, with one flap being longer than the other. When assembled, the longer flap on the upper zipper overlies the shorter flap on the lower zipper thus offsetting the opening and closing tabs of the two zippers, facilitating closure.

  • Patent number: 4083095
    Abstract: A method for manufacture of bag-like toy constructions assembled from individual vinyl panels. Designs, comprising the artwork on each individual panel, are printed continuously on vinyl sheets in precisely reproducible and spaced sequence. Each vinyl sheet has indexing and registration marks printed along opposed edges. After printing, a plurality of said vinyl sheets are stacked and fastened together in registered alignment. Templates are then utilized to outline each individual panel on the uppermost vinyl sheet. A cutting tool is then used to cut all sheets simultaneously along the template lines. The resulting panels are then seamed together with the printed design face of each panel facing outward, forming a completed toy construction.
