Sealing member and toner container provided with such a sealing member

A toner container for laser printers, copy machines and fax machines, said toner container having a surface with an opening for the passage of the toner, said toner container being provided with a sealing member for sealing the opening, whereby the sealing member comprises:

• a sealing film with a first face directed towards the surface for sealing the opening of the toner container and a second face opposite to said first face, said sealing film comprising a longitudinal central strip intended to be torn off, said central strip extending from a first end up to a second end and having a substantially predetermined width,
• a wiping element for wiping the portion of the first face of the sealing film corresponding to the central strip when contacting the torn central strip with the wiping element,
• a pulling member bound to the first end of the central strip, said pulling member being intended to extend before the tearing off of the central strip at least partly above the second face of the sealing film,
• in which the wiping element is attached to a component selected from the group consisting of the sealing film, a foam layer attached to the sealing film, a non foam support attached to the sealing film, and combinations thereof, by at least a connecting means selected from the group consisting of:
• combination of at least a first welding and a second welding;
• one connecting element attached to the component by a first welding and a second welding,
• two distinct connecting elements, a first of which is attached to the component by a first welding, while the second is attached to the component by a second welding,
• two distinct connecting elements, a first of which is attached to a first component by a first welding, while the second is attached to another component by a second welding, and
• combinations thereof,
• whereby the first welding and the second welding are distant from each other so as to define there between a passage for the torn central strip.

A sealing member for sealing an opening of a surface of a toner container for laser printers, copy machines and fax machines, said sealing member comprising:

• a sealing film with a first face intended to be directed towards the surface for sealing the opening of the toner container and a second face opposite to said first face, said film comprising a longitudinal central strip intended to be torn off, said central strip extending from a first end up to a second end and having a substantially predetermined width,
• a wiping element for wiping the portion of the first face of the sealing film corresponding to the central strip when contacting the torn central strip with the wiping element, the wiping element having two lateral side portions and a central portion extending between said lateral portions,
• a pulling member bound to the first end of the central strip, said pulling member being intended to extend before the tearing off of the central strip at least partly above the second face of the sealing film,
• in which the wiping element is attached to a component selected from the group consisting of the sealing film, a foam layer attached to the sealing film, a non foam support attached to the sealing film, and combinations thereof, by at least one connecting means for ensuring a pressure between the lateral portions of the wiping element and the component, whereby a passage is defined between said lateral portions of the wiping element, and between the central portion of the wiping element and the component.
