Abstract:
A developer material cartridge for use in a developer unit of an electrostatographic reproduction machine, the developer material cartridge comprising:(a) a housing defining a developer material containing chamber and an open end into said chamber; and (b) a robust multiple function seal assembled to said open end for retaining developer material within said housing during shipment, installation, and operational dispensing of developer material from said housing, said multiple function seal comprising a single member having a first end surface and a second and opposite end surface, said single member also including: (i) a first end portion having a first, impermeable, thickness and said first end surface for sealing said open end into said developer material containing chamber during shipment, installation, and operational dispensing of developer material from said housing, (ii) a second end portion adjoining said first end portion, said second end portion having a second thickness including said second and opposite end surface, and a plurality of slits cut through said second and opposite end surface into said second thickness; and (iii) a lead-in recess formed into said second and opposite end surface for enabling non-damaging coupling therewith of a machine interface member during installation, thereby avoiding undesirable risks of seal damage and developer material spills.
