Trapper Keeper is a brand of loose-leaf binder. It was created by Mead. Popular with students in the United States, Canada 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 wrap around flap with a Velcroclosure .
Trapper Keepers usually had a theme, such as a cartoon, television show, or video game. Between 1988 and 1995, “Designer Series” Trapper Keepers featured abstract designs and later computer-generated images.
The binder got its name because it was sold in combination with pocket folders designed by Mead called “Trappers”, which differed from other pocket folders in that the pockets’ three sides connected with the bottom, outside edge, and top of the 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 3-ring binder, including a Trapper Keeper.
In 2007, a new version of Trapper Keeper featured a magnetic closure in place of the Velcro closure, a customizable front cover, and binder dividers instead of Trapper folders.
In 2014, another new version of the Trapper Keeper was released, featuring a metal button closure, as well as a new feature called “Snapper Trappers”, which are plastic strips that act as dividers and they can have regular notebooks attached to them in addition to folders and dividers; the Snapper Trappers can be placed or removed without having to open the rings of the binder.
