Description

Technical field

The technical solution concerns a toner cartridge toner cartridge closure that is used in laser printers, copiers, fax machines or other printing devices.

BACKGROUND OF THE INVENTION

The closure is fixed by gluing or welding to the neck of the discharge opening of the toner supply container and closes the discharge opening. Its task is to prevent toner leakage when handling the cartridge eg. for shipping and storage before installing it in the printer. Another important feature of the cap is the ability to open and release the toner flow from the cartridge into the working portions of the image preparation cartridge after transferring it to the paper before inserting it into the printing device.

SK U 4861 describes a toner cartridge closure for laser printers, copiers and fax machines, which consists of a body for covering the discharge opening and its continuing elongated portion - the tail. To open the toner by removing the center belt, the top of the toner cartridge has longitudinally extending upper cutting tools that are rigid and are made of hard paper, plastic or metal. Their edge is located along the opening line. At the bottom of the body on the opening line opposite the upper cutting tools are located lower cutting tools that are movable and are made of a metal foil or a sheet of rigid plastic. The lower cutting tools can be combined. The width of the paired lower cutting tools is identical to the width of the tail or of the tail. is the same as the width of the center belt.

SUMMARY OF THE INVENTION

The toner cartridge lid of laser printers, photocopiers and fax machines consists of a body to cover the discharge opening and its continuing extension - the tail, to open it by removing the center belt. At the top of the body there are upper cutting tools spaced apart from each other at the width of the tail, which are rigid and are firmly fixed to the closure body. At the bottom of the body on the opening line opposed to the upper cutting tools is placed

-2-bottom cutting tool that is movable. The essence of the technical solution is that the upper cutting tools and the upper central belt, which is loosely placed on the body, form a monolithic upper joint part. The top cutting tools are defined by two perforations. The upper middle strip is removable after installation at the perforation site.

It is preferred that the upper middle belt is provided with bending lines to form a mounting handle.

The present solution facilitates handling of the toner cartridge during installation and its precise fit on the neck of the discharge opening of the toner cartridge.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution is further explained by means of examples and drawings, in which:

DETAILED DESCRIPTION OF THE INVENTION

-3Technical solution solves toner cartridge closure toner cartridges, which are used mainly in laser printers, copiers and fax machines. The cap protects the toner in the toner cartridge from moisture during storage of the cartridge and prevents it from being lost during transport and handling of the cartridge before installing it. The cap must be opened before use in the printing device.

The present invention is concerned with closures that open destructively by removing the central strip 4 from the closure body 1. To separate the central strip 4 from the closure body 1, there are integrated cutting tools, upper cutting tools 9, which are fixed and a lower cutting tool 10, which is movable. The lower cutting tool 10 may be supplemented by strips 22 to form a planar surface. The bottom of the breech may be provided with a frame 31, which is formed by a layer of permanent adhesive. To protect the adhesive layer, the frame 31 is provided with a protective layer 32 consisting of siliconized paper or foil. To facilitate and safely handle the closure, the closure has an upper joint member 30 that includes upper cutting tools 9 and an upper center belt 29. The upper joint member 30 is a monolith formed of a single piece of material. The two longitudinal perforations 28 on the upper common panel 30, spaced apart by the width of the tail 2, form upper cutting tools 9 which are separated by an upper middle band 29. The upper middle band 29 is fixed to the closure body 1 by gluing or welding only in place upper cutting tools 9. The upper cutting tools 9 are defined by two perforations 28. The upper middle band 29 is not firmly connected to the closure body 1. The upper central belt 29 may be provided with bending lines 27, e.g. in the end portion of the closure or in the middle portion. Upon bending of the upper middle web 29 in the bending and shaping lines 27, mounting handles 26 are formed which facilitate handling of the closure during installation and its accurate fit to the neck of the discharge opening of the toner cartridge. After the closure has been installed, the upper center belt 29 is pulled off the top shearing tools 9 by pulling the mounting handle 26 and removed.

In the actual opening of the closure, the central strip 4 is separated from the closure body 1 precisely in the desired opening line by manually pulling the end of the tail 2 gradually from the tail bending point 2 to the opposite end of the closure.
