Abstract

A toner cartridge for use in a copying machine for supplying fresh toner to the developer for the machine. The cartridge is formed with an elongated opening to permit discharge of toner when inverted. A removable flexible strip covers the opening and is detachably held to the cartridge by adhesive material. The pattern of the adhesive material is non-linear at the portions of the cartridge adjacent the ends of the opening so that upon an application of a pulling force upon the strip to detach the same, the resistance force is gradual.
