Abstract

PURPOSE:To prevent a damage in conveyance and to facilitate extremely easily and securely supplementary toner by protecting a toner scatter preventing seal which is stuck to the opening part of a toner casing by a cover body. CONSTITUTION:When the cover body 3 is drawn out after the toner casing 1 is attached, the toner scatter preventing seal 2 stuck to the circumferential edge of the opening part 11 is peeled off to its half and at the same time, a grip piece 21 fitted to the surface of the seal 2 is also exposed in the casing 1 together with the cover body 3. Therefore, the grip piece 21 is drawn to this side to draw out the remaining seal part stuck to the opening part 11, and the seal is peeled off completely in the end. A scraping member 34 is rubbed against the internal surface of the seal 2 contacting toner in said drawing-out process to remove the toner. The cover body 3 is pressed in after the toner is discharged to cover the opening part 11, preventing the remaining toner from scattering.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toner cartridge used for replenishing toner to copying machines and the like.

When replenishing toner in a copying machine that uses a dry development method, the toner from the bottle is usually poured directly into the toner hopper, but with this method, the toner scatters frequently.
There is a problem that degrades the performance of shading.

On the other hand, toner cartridges with a toner scattering prevention sticker folded in two and glued to the opening are also used; If the toner comes off or is torn, a large amount of toner will scatter, causing problems such as significant contamination of the surrounding area.

An object of the present invention is to solve this problem and provide a new toner cartridge that does not cause toner scattering not only when replenishing toner but also at other times. Details will be explained based on illustrated embodiments.

Each of the drawings shows an embodiment of the present invention,
In the V middle code 1, there are outer overhangs 1 to 12 on both sides of the opening 11.
．． 12, the opening 11 is sealed by a toner scatter prevention seal 2, which will be described later, and the outside thereof is loosely engaged with the above-mentioned outer protrusion 12.12 of the toner casing 1. The stop 1 is covered by a lid 3 that slides in the longitudinal direction of the casing 1.

By the way, the above-mentioned toner scattering prevention seal 2 is attached to the toner casing 1 at t9. #'? It is formed as a sheet with twice the length, and one half of the sheet is folded in half and attached to the periphery of the opening 11 of the toner casing 1, and the other half is placed along the top surface of the lid 5, and the end portion is attached. It is attached to a dowel 32 of a handle 31 that is bent downward in front of the lid body 30, and on the surface of the handle 31, which is about an inch away from the other end of the seal 2, there is a seal for removing the seal 2 from the opening 11. grip piece 21
is pasted.

Note that reference numeral 15 in the figure is a stopper that is cut and raised or planted on the upper surface of the front side of the outer projecting portion 12 of the toner casing 1, and is a stopper that protrudes from the inner protrusion 33 provided on both sides of the rear end of the lid body 3. The toner scraping member 34 is attached to the upper surface of the rear end of the lid 3 to prevent the lid 3 from coming off.

In the above-described embodiment, when the cartridge is set in the developing device of the copying machine and the lid 3 is pulled forward, the toner scattering preventive material pasted on the periphery of the opening 11 of the toner casing 1 is removed. The seal 2 is pulled by the molten material 3 and is peeled off halfway, and is exposed from the inside of the casing 1 together with the 21 gripping pieces that were not attached to the surface of the seal 20 and the lid 3 at the same time as the sweet potato (Fig. 2). (B)).

Therefore, if you hold the protruding grip piece 21 and pull it toward you from this state, the remaining part of the seal stuck to the opening 1] part 11 will also be pulled out (Fig. 2 e→), and finally the opening 11 will be pulled out.
The inner surface of the seal 2, which was in contact with the toner in the pan of this drawer, must be completely peeled off.
Well, it comes into sliding contact (~
, attached there-#1. toner is removed. In this way, when the seal 2 is inserted into the opening 11 and the toner inside is transferred to the toner storage, the scoop lid 3 is pushed in, and the lid 3 is inserted into the opening 11f''i of the casing 1. This prevents residual toner from scattering.

As described above, according to the present invention, since the toner scattering prevention seal attached to the opening of the toner casing is V-shaped so as to be protected by the lid, the seal is not damaged during transportation. There is no need to worry about this, as one half of the seal folded in half is pasted on the opening of the casing, and the seal at the opening is peeled off by pulling out the lid to which the other end of the seal is attached. As long as the lid is pulled out while it is set in the toner storage section, the toner can be transferred to the waste collection section without causing toner scattering.Furthermore, the lid can be sealed by simply pulling the grip that is exposed when the lid is pulled out. The toner replenishment operation can be easily and reliably performed, such as by being able to remove the toner from the casing.
