Abstract

PURPOSE:To replenish toner and to prevent the toner from scattering with a simple operation by making plural string members pass through small holes formed in the center of the upper part and the bottom part of a toner box so that they are inserted into the toner box and drawing them out to the outside through a ring member and the small holes. CONSTITUTION:Four string members are tied to an open ring 11 in the center of the upper part of the toner box. The strings penetrate the small hole 3a on the upper part and pass through a terminal ring 13 on the upper surface of the bottom part and the small hole 3b on the back surface of the bottom part. Then, they respectively extend toward four corners one by one, pass through the small holes 3c-3f and enter the box 3 again and they are tied to the terminal ring 13 in the center of the bottom part. By pulling the ring 11 on the upper part of the toner box, tension acts on the string members 12a-12d and the bottom part of the box is torn toward the center from the four corners, whereas the toner housed inside all drops.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a toner supply container for electrophotographic copying machines, facsimile machines, laser printers, etc. that perform dry development using an electrophotographic method.

(Prior Art) Conventionally, in a dry type developing device that stores and replenishes toner in a toner replenishment container, an opening having a shape that fits the toner replenishment opening of a toner box is covered with an unsealable member.
A drawstring is locked to the unsealing member, and the drawstring is fixed by a pull fixing means in the toner storage state, thereby sealing the opening with the unsealing member, and fixing the toner supply container in an inverted state. A toner replenishing container is known in which the opening member is opened and toner is replenished by removing the means and loosening the drawstring.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, the toner supply container must first be turned upside down and the fixing member at the bottom must be peeled off. At this time, the string is pulled and loosens, causing the toner to spill out. Furthermore, since the bottom of the toner replenishing port is opened at the top of the toner replenishing port to replenish the toner, there is a problem that the toner may scatter around the toner.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems by forming small holes in the center of the top and bottom of the toner box, and passing a plurality of string members through the small holes in the top of the toner box. Insert it into the
It is characterized in that it is passed through a ring member, inserted into a small hole in the bottom and pulled out, and each set is inserted into the toner box from a corner of the toner box and coupled to the ring member.

(Example) A detailed description will be given based on the example shown in FIGS. 1 to 5. There is a release ring 11 approximately in the center of the upper exterior of the toner box 3, and four string members are tied to it.

Each of them forms a bundle and passes through the small hole 3a on the top of the toner box, passes through the terminal ring 13 at the top of the bottom, and
The small hole 3b on the bottom is also penetrated to reach the bottom outside of the toner box. One string member 12 is formed from the bottom outside of the toner box and extends toward the four corners, forming small holes 3c, 3d, and 3e, respectively.
, 3f and enter the box again. From there, the four string members 12 each head toward a central terminal ring 13 and are tied to the terminal ring 13 there.

Next, the effect will be explained. When the release ring 11 at the top of the toner box 3 is pulled, the force is applied to the string members 12a, 1
2b, 12c, and 12d, and if the tension exceeds a certain limit, the bottom of the box will be torn from the four corners toward the center due to the tension of the string member.

Due to the presence of the terminal ring 13 in the center of the bottom, the tension of the tension ring is distributed in all directions, and breakage occurs from the periphery. When the breakage is completed, the bottom member of the toner box becomes as shown in FIG. 4, and all the toner contained therein falls out. When the release ring is pulled all at once, the terminal ring 13 hits the ceiling of the box and acts as a stopper for the string, indicating to the operator that enough paper has been pulled.

FIG. 5 shows another embodiment, in which the bottom members 3g and 3h in FIG. 4 have less hanging. Whether the fracture is in an X-shape as shown in Figure 2 or a 7-shape combined as in Figure 5, this can be achieved by making that part a little weaker than the other parts. For example, the toner box 3 is made of slightly thick paper (in FIG. 2, each folded part is made into a triangular shape, and in FIG. 5, it is made into a trapezoid and a triangular shape), and the bottom part is made of a double structure with thinner paper pasted. Since the paper is thin at the part to be torn, it will easily break at that part.

(Effects) According to the present invention, small holes are formed at the center of the top and bottom of the toner box, and a plurality of string members are inserted into the toner box through the top small holes, passed through the ring member, and inserted through the bottom small holes. Then, each set is inserted into the toner box from the corner of the toner box and connected to the ring member.

- The toner stored in the toner box can be replenished to the bottom by simply pulling the string, which not only keeps the operator's body clean, but also prevents toner from scattering all around.

・The toner box itself can be made of paper and can be manufactured at a very low cost since it consists of string and ring members.

(2) Effects on claim 2 - Replenishment operations can be easily performed by simply pulling the release ring.

(3) Function and effect for claim 3 - Since the broken shape can be made constant at the bottom and the hanging portion is shortened, it is possible to reduce the amount of dirt when the toner box is removed due to contact with toner after replenishment. can.
