Trapper Keeper is a brand of loose-leaf binder created by Mead. Popular with students in the United States and parts of Latin America from the 1970s to the 1990s, it featured sliding plastic rings (instead of standard snap-closed metal binder rings), folders and pockets to keep schoolwork and papers, and a wraparound flap with a Velcro closure (originally a metal snap closure).
The binder got its name because it was sold in combination with pocket folders designed by Mead called “Trappers”. Trappers were different from other pocket folders in that the pockets’ three sides connected with the bottom, outside edge, and top (as opposed to the bottom, outside edge, and spine of most pocket folders). This design prevented papers from falling out of the Trapper’s pockets when it was closed. Trappers were three-hole punched so that they could be put in any notebook, including Trapper Keeper.8 Comments
