US 5,116,301 A · Method of making a double zipper pouch

Abstract

A double zipper pouch having first and second pockets adjacent one another and with a common wall portion, each pocket having an opening for receiving contents such as identification papers. The first and second pockets are formed so that their openings are displaced relative to one another. Pressure actuated resealable fasteners are disposed adjacent the openings in each of the first and second pockets. First and second indicators are also disposed adjacent the openings to provide an indication of the location of the associated opening. The indicators are preferably different from one another so as to provide an identification for the associated pocket. An adhesive material is formed on the back of the first pocket for affixing the pouch to, for example, a package.
