Sealing film having a substantially longitudinal central strip to be torn out between a first end and a second end, whereby the central strip has a substantially constant width and a substantially longitudinal central axis, and whereby an end of the central strip adjacent to one end selected from the first end and the second end has a width which varies from the substantially constant width of the central strip to an end width lower to the substantially constant width of central strip.

Sealing member for toner cartridge

Sealing member formed by a sealing film with a substantially longitudinal portion to be torn out, wherein the sealing film is connected to a pulling strip made of a layer, with fibers extending in a direction forming an angle between &minus;60&deg; and &plus;60&deg; with respect to the tearing direction of the longitudinal portion to be torn out.

A sealing film for a toner cartridge or container. The sealing film has a layer with a thickness of between 20 &mgr;m and 1 mm and has at least on substantially linear tearing direction. The layer also includes surface elements that extend in a direction that is different from the preferred tearing direction of the sealing film.

The present invention provides a sealing film for a toner cartridge. The sealing film includes a layer with a preferred linear tearing direction. The layer is provided with longitudinal surface elements defining a strip to be torn out. The longitudinal surface elements extend in an inclined direction with respect to the strip to be torn out. The strip to be torn out includes a pulling means having a sufficient tearing resistance for preventing a separation between the pulling means and the strip to be torn out during a tearing operation.

Sealing member for toner container having a tearable central strip and being associated with connecting elements ensuring the pressing of the lateral portions of a compressible cleaning element, with respect to the portion of the cleaning element intended for cleaning the torn central strip.

Sealing member and toner container provided with such a sealing member

Tearable sealing member for unsealably sealing an opening of a developer, said tearable member comprising a seal film for closing the opening and a tearing member, in which the seal film is provided with a means for controlling a minimum width of the strip to be torn out during at least its partial tearing.
