Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for discarding a collected material of a collected material processing device of an electrophotographic apparatus.

[Conventional technology]

Regarding the waste container of the conventional collected material processing equipment,
As disclosed in Japanese Patent Application Laid-Open No. 55-178158, a hole box is made of a plate having necessary and sufficient rigidity, and a folding box is formed by providing folds on four sides.

[Problems to be solved by the invention]

However, in the case of the container of the conventional system, since the box itself is a foldable type, the force for returning to the original flat state after the box is opened is hard to be held by the worker, and it is difficult to mount and remove the box. On the other hand, the rigid material for forming the box has a problem that the sealed portion of the mating portion is peeled off by an external force such as twisting. SUMMARY OF THE INVENTION An object of the present invention is to provide a toner disposal container that has good airtightness and has sufficient rigidity to hold the toner.

[Means for solving the problem]

The feature of the present invention is a container having flexibility and elasticity comprising a bottom surface, four side surfaces and an upper surface provided with an inlet opening, and covering three adjacent side surfaces among the four side surfaces of the container from outside, and A first container reinforcement body made of cardboard having three side surfaces adhered to a central side surface of the three side surfaces, and a side surface of the container opposite to the side surface to which the first container reinforcement body is adhered, and A second container reinforcement body made of cardboard having one side surface bonded to a side surface, wherein both ends of the first container reinforcement body and both ends of the second container reinforcement body are engaged to surround the container. In the collected waste container of the electrophotographic apparatus.

[Action]

The container for toner disposal has a double structure and is made of a material which is flexible and sufficiently sealed at the joint inside to prevent toner leakage from the joint. In addition, the outside is made by folding and assembling a plate member with sufficient rigidity, so that the part that will be the rear surface of the assembly can be folded to improve the rigidity of the container after assembly,
Improved handleability.

〔Example〕

Hereinafter, an embodiment of the present invention will be described. Generally, an electrophotographic apparatus uses a one-component developer or a two-component developer. In the case of the one-component developer, the toner itself is developed in the case of the two-component developer, and the toner is developed and transferred to paper or the like. However, the transfer efficiency at this time does not become 100%, and untransferred toner and the like remain on the photoconductor. The dust and paper dust adhering to the surface of the photosensitive material or paper scraped off from the surface of the photoreceptor are mixed into the residual toner and the like. Will be done.

As shown in FIG. 1, the photoreceptor and the cleaning device 1 are generally installed horizontally, so that the photoconductor and the cleaning device 1 are unloaded from the cleaning device 1 by a first duct 8 extending horizontally and a transport coil 7 provided inside the duct. Is done. Usually, the transfer coil 7
Is set slightly longer than the first duct 8, and the toner 9 falls from the tip of the first duct 8 and is collected in the container 13. Note that the container 13 is reinforced by the reinforcing members 12 and 14. By the way, in the state where the container 13 is removed, the second
The duct 4 is pushed out until the stopper 4 a hits the handle base 2. Since the horizontal portion 4c of the second duct 4 is an extension of the first duct 8, the horizontal tip of the duct is longer than the transfer coil 7. Therefore, even if vibration for replacing the container 13 is applied, the toner 9 in the first duct 8 is retained in the second duct 4, so that toner spillage into the apparatus is prevented. As will be described later, since the container 13 for collecting and discarding the toner is provided with the container for supplying the toner together with the container for supplying the toner, the state where the container 13 is not in the main body is only for replacement and the above simple countermeasures for toner spillage are sufficient. That's it.

In this example, the first duct 8
A packing 8 is provided between the first duct 4 and the second duct 4 in consideration of slippage due to a clearance.

Next, the collected waste disposal container will be described with reference to FIGS. 2 and 3. FIG. The container 13 having flexibility and elasticity is surrounded and reinforced by the first container reinforcing member 12 and the second container reinforcing member 14 made of cardboard. That is, the container 13 is configured as a flexible and stretchable container having a bottom surface, four side surfaces, and an upper surface having an entrance opening. Further, the first container reinforcing member 12 covers three adjacent side surfaces of the four side surfaces of the container 13 from outside, and
The cardboard is made of cardboard having three sides adhered to the central side of the three sides.

Further, the second container reinforcing member 14 is made of cardboard which covers the side surface of the container 13 opposite to the side surface to which the first container reinforcing member 12 is bonded, and has one side surface bonded to this side surface.

In addition, folds are formed between the respective side surfaces of the first container reinforcing member 12. Also, claws 12c are provided at both ends of the first container reinforcing member 12, and holes 14a are provided at both ends of the second container reinforcing member 14 to engage with the claws 12c. Further, an engaging claw is provided on the upper surface of the first container reinforcing member 12.
12d and 12e were provided. The container 13 in which the toner 9 is stored is a bag having flexibility and elasticity, and is bonded to the opposing surfaces of the first container reinforcing member 12 and the second container reinforcing member 14. When the container is assembled by this bonding, the container 13 generates a pulling force against the projecting force of the side surface of the first container reinforcing member 12, so that the first container reinforcing member 12 and the second container reinforcing member 14 are engaged. However, it does not come off and maintains rigidity. Further, the upper surface provided on the first container reinforcing member 12 is bonded so as to make the toner inlet 13a of the container 13 rigid. The portion to be bonded to the opposing surfaces of the first container reinforcing member 12 and the second container reinforcing member 14 may be only the outer periphery, and the central portion may not be required. Therefore, the container 13 may be a cylindrical member having a hole at the center where the above-mentioned bonding is unnecessary. However, the container 13
Since it is easier to make a bag, a bag was used in this example. In this embodiment, the toner inlet 12a is set to the upper side, and the first container reinforcing member 1
2 and the second container reinforcement 14 provided rigidity, so that L3 ≦ L1
− (L2 ÷ 2), the container 13 is made thin, and when the second container reinforcing member 14 is pressed against the first container reinforcing member 12, the toner inlet 12a is formed.
The surface with the mark was pulled by the second container reinforcement 14 so as to cover the second container reinforcement 14. Hole of second container reinforcement 14
By setting the claws 14a and the claws 12d of the first container reinforcing member 12 so as to overlap the holes 12b, the two surfaces of the first container reinforcing member 12 having the claws 12c also overlap the surfaces having the toner inlet 12a, respectively. First
The container reinforcement 12 can be folded to the size of almost the maximum surface.

〔The invention's effect〕

According to the present invention, it is possible to reliably supply a toner disposal container which is easy to manufacture, inexpensive, easy to assemble with a container, has high rigidity after assembling, and is easy to handle at the time of toner supply.
