摘要:
Eine Verschlusseinrichtung für Tonerbehälter (1) weist einen flächigen Träger (5) mit einer mittleren Durchbrechung (7) auf, die mittels einer Verschlussfolie (6) verschlossen ist. Die Verschlussfolie (6) weist einen ersten Abschnitt (8, 9) mit zwei seitlichen Streifen (9) und einem mittleren Streifen (8) und einen zweiten Abschnitt in Form einer Zugeinrichtung (11) auf. Der mittlere Streifen (8) ist von den seitlichen Streifen (9) entlang zweier Reißlinien (10) abreißbar. Die seitlichen Streifen (9) sind mit dem Träger (5) verbunden. Die Zugeinrichtung (11) ragt von einem Stirnende (16a) des ersten Abschnittes ausgehend bis über dessen zweites Stirnende (16b) hinaus. Die Zugeinrichtung (11) ist durch die Durchbrechung (7) geführt und ragt auf der dem ersten Abschnitt gegenüber liegenden Seite des Trägers (5) über diesen hinaus. Da die Zugeinrichtung (11) und in weiterer Folge der mittlere Streifen (8) durch die Durchbrechung (7) gezogen werden, werden die seitlichen Streifen (9) beim Abreißen durch den sich dadurch ergebenden Winkel etwas gegen die seitlichen Stege (12) gezogen, wodurch ein Abreißen oder Ablösen der seitlichen Streifen (9) von den seitlichen Stegen (12) vermieden werden kann.
摘要:
A sealing member for sealing a developer accommodating portion for accommodating a developer includes (a) a sealing portion for openably sealing an opening of said developer accommodating portion; (b) an extended portion extended from said sealing portion, said extended portion having a width, measured in a direction of extension, which is smaller than that of said sealing portion; (c) a connecting edge for connecting an edge of said sealing portion adjacent said extended portion and a side edge of said extended portion extending in the direction of the extension; (d) a tearable portion capable of being torn to open said opening sealed by said sealing portion, wherein an end of said tearable portion is provided in said sealing portion, and the other end thereof continues to said connecting edge, wherein said tearable portion extends between said one end and said other end substantially parallel with the extension direction.

In a transfer system (19) located in a printer, a suction spout communicating via a pipe with the development unit is arranged in a vertically movable manner inside a protective conduit (28) impervious to the toner. The transfer system comprises at its lower end an adapter serving for connection of the toner container (10). During replacement, the new container (10) is made to pivot via a support system (32) onto the adapter and connected with the latter. A cutting system (31) associated with the adapter then pierces a sealing film of said toner container (10). For emptying, the suction spout is immersed vertically in the toner container (10), the bottom of which has a funnel-shaped configuration serving as a toner storage area.
摘要:
Le réservoir de toner (10) décrit possède un fond en forme d'entonnoir avec une région de stockage du toner très profonde. Les parois latérales du réservoir sont constituées de surfaces planes, et au moins une paroi (12) forme une surface d'appui pour le réservoir (10). Pour empêcher le toner d'adhérer aux parois du réservoir, celles-ci sont inclinées. Le réservoir (10) se vidange par l'intermédiaire d'un bec aspirant (10) agencé de manière déplaçable verticalement. Il s'utilise donc aussi bien comme bac de transfert de toner frais que comme bac collecteur de toner usagé.
摘要:
A toner supply container detachably mountable to an image forming apparatus, includes a main body, provided with an opening for permitting discharge of the toner, for accommodating the toner; a sealing member for unsealably sealing the opening; wherein the opening is unsealed by tearing a part of the sealing member, wherein a pattern of welding with which the sealing member is welded on the main body of the container is inclined inwardly with respect to a tearing direction at a laterally outward end portion at a tearing starting side end portion.

Sealing member (1) comprising a sealing film (2) with a substantially longitudinal portion to be torn out, wherein the film is connected to a pulling means comprising at least a layer comprising fibres extending in a direction forming an angle comprised between -60° and +60° with respect to the tearing direction of the longitudinal portion to be torn.
摘要:
The present invention provides a cartridge detachably attachable to a main body of an image forming apparatus which comprises a developing device, and the developing device includes a developer containing container, a developing container having a developer bearing member, a removable seal member for covering said opening portion, and a detecting portion for detecting an amount of the developer within the developing container, and the main body of the image forming apparatus detecting whether the seal member is removed or not by detecting the detecting portion by the main body of the image forming apparatus.
