Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a toner storage container used to supply toner to a developing device.

(Prior art) Toner cartridges used to replenish toner to the developing device usually have a sticker attached to the toner discharge port with a strong adhesive to prevent shocks during transportation. It is constructed so that it will not peel off even if it is twisted.

For this reason, peeling off this type of sticker requires a lot of force from your fingertips, and the reaction when you peel it off can cause the cartridge to shake, causing the toner inside to scatter, and toner adhering to the inner surface of the sticker can damage clothing, etc. This may cause problems such as contamination.

(Purpose) The present invention has been made in view of the above problems, and its purpose is to provide an improved toner storage container whose seal can be easily peeled and which can prevent toner from scattering. It is in.

(Structure) That is, in the present invention, one half of the bifold seal member is attached to the opening edge of the container, and the other half of the bifold seal member is provided with a removable winding member at one end, and is rotatably pivoted toward one side of the container. The toner storage container is supported on the periphery of a supported winding roll, and the seal is peeled off while winding up.

Therefore, the details of the present invention will be explained below based on illustrated embodiments.

The drawing shows one embodiment of the present invention, and the toner cartridge main body designated by the reference numeral 1 in the drawing has one half 3a of a seal 3 folded in two.
It is attached to the mouth edge of the cartridge from one longitudinal end to the other end so as to cover the opening 2, and at one end of the cartridge main body 1 where the end of the return side 3b of this seal 3 is located, A bracket 4 is integrally formed to protrude, and is provided with a shaft hole 6 having an insertion opening 5 at the bottom side of the cartridge body 1.

Reference numeral 7 denotes a winding roller that is removably supported by the shaft hole 6, and the end of the return side 3b of the seal 3 described above is affixed to the circumferential surface of the top.
A handle 9 for rotating the roller 7 is detachably attached to one end of the roller 7.

In the figure, reference numeral 10 is a pin on the cartridge main body 1 that fits into a hole 13 in the side wall of the hopper 12 of the developing unit and serves as a rotational fulcrum during installation, and 11 is a pin that fits into a recess provided in the side wall of the hopper 12. The convex portions on the cartridge body 1 shown in FIG.

In the embodiment described above, first the hopper 1
After fitting the pin 10 into the hole 13 in the side wall 2, the toner cartridge main body 1 is rotated using the pin 10 as a fulcrum so that the opening 2 is facing downward, and the toner cartridge main body 1 is inserted into the hopper 12.
Attach it on top.

Next, when the handle 9 is coupled to the take-up roller 7 that is pivotally supported at the end of the cartridge body 1 and rotated, one half 3a of the seal 3 that was firmly attached to the opening 2 of the cartridge body 1 is removed. As the return side 3b is wound around the roller 7, it is gradually peeled off and the toner inside the cartridge body 1 is released into the hopper 12.

(Effects) As described above, according to the present invention, since the toner attached to the hopper is replenished with the opening facing down, toner can be replenished evenly and reliably, and one half of the toner is in the container. The other half of the two-fold sticker stuck to the opening of the container is wound up by a take-up roll that is pivoted on one side of the container, so all you have to do is attach the container to the hopper and rotate the wind-up member. Not only can the sealing member be peeled off without scattering the toner, but also a peeling force can be applied to the attached seal in a direction parallel to the opening, thereby applying unreasonable force to the toner storage container. You can peel off the sticker with stable force without any pressure.

In addition, since the force for peeling off the seal is applied near the rotation axis when installing the toner storage container, the toner storage container does not rotate and cause toner to scatter, and the toner storage container Since the winding member is located on the front side in the mounting direction of the container, the user can easily roll it up by hand.

In addition, since it is peeled off using a winding member with a diameter larger than the diameter of the winding roll, even when the toner cartridge is mounted on the hopper, the seal is firmly attached with a small amount of force. It can be peeled off.
