Reinforced toner seal tear strip construction

摘要

A synthetic resinous tear strip seal or toner cartridge used in electrostatic copy machines, in which the longitudinal central area of the strip is reinforced by laminating additional planar material thereto in the area overlying the elongated opening in the toner cartridge, and preferably along at least part of the tear strip. The material may be similar to that of the seal, or of other material selected for electrostatic conductivity to dissipate the electrostatic attraction of the seal material to the toner particles in the toner cartridge hopper. Typically, a thin coating of aluminum is applied to the material which is of a synthetic resin.
