Abstract

PURPOSE:To prevent toner from scattering from a toner cartridge container by sealing a toner cartridge container with a thin film body, and covering the toner cartridge container with a lid body after the thin film body is removed. CONSTITUTION:The toner hopper container 1 has a toner supply opening 1a in its top surface and is mounted on an electrophotographic device main body and the toner cartridge container 2 has a toner supply opening 2a, which is linked with the toner supply opening 1a, sealed in its reverse surface with the thin film body 6 and is coupled detachably and airtightly with the toner hopper container 1; and the toner hopper container 1 and toner cartridge container 2 are combined in a pair. The toner hopper container 1 has grooves 1b and 1b along the opening opposite edges of the toner supply opening 1a, and the lid body 3 is fitted and held to close the toner supply opening 1a. Further, the toner cartridge container 2 has an opening 2c for receiving the upper end edge of the toner hopper container 1 airtightly in its reverse surface and a lid body 5 is held in the groove 2b to cover the toner supply opening 2a. When the lids 3 and 5 are drawn out, the thin film body 6 is peeled to link the openings with each other. Consequently, toner is prevented from scattering from the cartridge.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field 1] The present invention relates to electrophotographic apparatus, and more particularly to toner cartridges and toner hoppers.

(Conventional Technique VFI) Conventionally, this type of toner cartridge and toner hopper is operated by opening the lid of the toner hopper and then removing the toner.
The structure was such that the toner was transferred to the toner hopper by placing the cartridge over it and pulling out the cellophane lid, and then finally removing the toner cartridge and closing the toner hopper lid.

[Problem to be solved by the invention]

In the conventional toner cartridge and toner hopper described above, when the toner cartridge is removed from the toner hopper after the toner transfer operation, the toner in the toner hopper scatters to the outside.

In addition, once the cellophane is removed from the toner cartridge after work, it is impossible to reattach the lid and remove the toner remaining inside the toner cartridge or toner attached to the cellophane. The drawback is that it spills and splatters.

An object of the present invention is to provide a toner cartridge and a toner hopper that solve the above problems.

[Means for Solving the Problems 1] In order to achieve the above-mentioned object, the toner cartridge and toner hopper of the present invention have a toner supply port opened in the upper surface thereof, and are mounted on the main body of an electrophotographic apparatus. a container, a toner cartridge container having a toner supply port in communication with the toner supply port in the lower surface thereof, and a toner cartridge container hermetically and removably connected to the toner hopper container; The toner hopper container includes a lid that closes the toner supply 11, and the toner cartridge container includes a thin film that seals the toner supply port, and a lid that closes the toner supply port after the thin film is opened. It is equipped with the following.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view showing an embodiment of the present invention, Fig. 2(a)
is a perspective view showing a toner hopper container in the present invention;
FIG. 2(b) is a perspective view showing a toner cartridge container according to the present invention, FIGS. 3(a) and 3(b) are perspective views showing a toner hopper container and a lid used for the toner cartridge container, and FIG. Figures (a) and (b) are perspective views showing the relationship between the toner cartridge container and the lid;
FIG. 2 is a perspective view showing the relationship between the toner hopper container and the lid.

In FIGS. 1, 2(a) and 2(b), the toner cartridge and toner hopper of the present invention have a toner supply port 1a opened on the upper surface thereof, and the toner cartridge and toner hopper are mounted in the main body of an electrophotographic apparatus (not shown). - It has a set of a hopper container 1 and a toner cartridge container 2, which has a toner supply port 2a opened in its lower surface and communicates with the toner supply port 1a, and is airtightly and detachably connected to the toner hopper container 1. .

The toner hopper container 1 is shown in FIGS. 2(a) and 5(a).
As shown in Q), grooves 1b and lb are formed along the opposite edge of the opening of the toner supply port 1a, and a lid 3 is fitted and held in the grooves 1b and lb, and the lid 3 closes the toner supply port 1a. Close the lid.

Further, the toner cartridge container 2 is shown in FIG. 2 (6).

As shown in FIG. 5(b), the lower surface thereof is provided with an opening 2C into which the upper edge of the toner hopper container 1 is hermetically received;
A frame material 4 for applying to the upper edge of the toner hopper container l is provided at a position recessed from the mouth edge of the opening 2C, a groove 2b is provided on the opposite edge of the frame material 4, and a lid body 5 is held in the groove 2b; Lid body 5
to close the toner supply port 2a. In addition, Fig. 4 (a
) and (c), one edge 6a of the thin film 6, such as cellophane, is attached to the innermost edge 5a of the lid 5 attached to the toner cartridge container 2 (marked O in the figure), and the thin film Attach the remaining edges 6b, 6c, and 6d of the body 6 to the opening edge of the toner supply port 2a of the toner cartridge container 2 (marked with an x in the figure).
Then, the toner supply port 2a is sealed with the thin film member 6.

Further, as shown in FIGS. 3(a) and 3(b), the lid 3 of the toner hopper container l has recesses 3a at the front side and the innermost part thereof.
, 3b, and on the other hand, the lid 5 of the toner cartridge container 2 has convex portions 5a, 5b on the front side and the innermost part thereof.
It is equipped with

The toner cartridge container 2 is filled with new toner for replenishment with its toner supply port 2 a sealed with a thin film member 6 , and the toner hopper container 1 has its toner supply port 1 a sealed with a lid 3 . It is mounted on the main body of the electrophotographic device with the lid closed.

When the toner in the toner hopper container 1 is used up and new toner is replenished from the toner cartridge container 2, the toner hopper container 1 is refilled as shown in FIG.
Place the toner cartridge container 2 on top. At this time, the upper edge of the toner hopper container 1 is received in the opening 2C of the toner cartridge container 2, and the toner hopper container 1 and the toner cartridge container 2 are hermetically coupled. In addition, as shown in FIGS. 5(a) and 5(c), the convex portions 5a, 5b and the concave portions 3a of both lids 3, 5,
3b are joined in a concave and convex manner and are integrated.

When the lids 3, 5 are pulled out in this state, both lids 3.5 are pulled out as one. At this time, the thin film member 6 sealing the toner supply port 2a of the toner cartridge container 2
It peels off at the X mark and is pulled out as the lid body 5 moves. As a result, the toner supply port 2a and the toner supply port 1a communicate with each other, and the toner in the toner cartridge container 2 is replenished into the toner hopper container l.

After the toner is replenished, when the lids 3 and 5 are pushed into the containers 1 and 2, the toner supply port 1a of the toner hopper container l is opened.
is covered by the lid 3, and the toner supply port 2a of the toner cartridge container 2 is covered by the lid 5.

Then, when the toner cartridge container kg2 is pulled up, the concave-convex connection between the side lids 3 and 5 is released, and the toner cartridge container 2 is separated from the toner hopper container l.

In this case, the toner supply of the toner cartridge container 2 [
After the thin film body 6 sealing the toner supply port 12a is opened, the toner supply port 2a is covered with the lid body 5.

Therefore, according to the present invention, residual toner is prevented from scattering from the toner cartridge container 2.

[Effects of the Invention] As explained above, in the present invention, the toner cartridge container is sealed with a thin film body, and the toner cartridge container is covered with the lid body after opening the thin film body, so that toner is not scattered from the toner cartridge container. can be prevented.
