Description

Sealing tape for preventing toner from leaking}

The present invention relates to a toner leak-proof sealing tape for a toner cartridge, and more particularly, to a toner leak-proof sealing tape that is easy to be bonded and has a sufficient adhesive strength as a simple structure.

Usually, a sealing tape is attached to the toner supply opening of the toner container, or a sealing means is provided so that the toner does not spill out to the outside by the sealing tape or the sealing means during storage and movement of the toner cartridge, and in use, the sealing tape is removed or the sealing means is used. By opening the toner to the printer or copier, the toner supply opening is opened so that the toner is supplied through the toner supply opening. As a sealing means, the sealing tape is sealed by adhering it around the toner supply opening via an adhesive or the like, and when opened, the tape is removed by pulling it to one side and pulling it out.

Also, in the case of a regenerated toner cartridge registered under Utility Model Registration No. 288579, after the toner is refilled in the toner container to reuse the toner cartridge of the printer or copier, the toner cartridge is recharged until it is installed in a device such as a printer or a copier. The toner seal which is inserted into the slit between the front body and the rear body of the toner container and seals the toner supply opening is fixed so as to prevent the toner from leaking to the outside or from getting wet. The silver body is made of reinforced plastics, and an elastic member such as a sponge is attached to the bottom surface to seal the contact surface, and a sealing is attached to the top surface to open the sealed state.

However, while the sealing means other than the tape is complicated in structure and expensive to manufacture, the sealing tape can be simply attached and used, but the sealing tape attached to the lower part of the toner supply roller is equipped with the toner supply roller. It is not easy to pull and remove the sealing tape in one direction, so that when it is not partially removed and ruptures, it causes a problem of smooth supply of toner, and also weakens the adhesive strength to prevent it. There is a problem such as peeling and leakage of toner during handling such as transportation.

Accordingly, the present invention has been made to solve such a problem, and is simple in structure and easy to manufacture, ensuring sufficient adhesive strength and easy to open, and providing a more effective toner leakage preventing sealing tape during recycling. Has its purpose.

Although the toner leakage preventing sealing tape may be adhered to the sealing tape attaching portion through a strong adhesive agent, the heat-sealed resin layer is formed on at least the lower surface of the sealing member and the lower surface of the sealing member so that the heat-pressure welding of a roller or the like provided with a heat source is possible. By means of fusion means such as a means, an ultrasonic fusion means, a laser fusion means, or the like, the opening member can be fused to the lower surface of the sealing member, and the sealing member to which the opening member is fused can be strongly bonded to the sealing tape attaching portion around the toner supply opening. Also, for this purpose, the sealing member is preferably such as a pulp that is easy to break in one direction in the longitudinal direction, and the opening member is preferably a laminate material such as a flexible material that can easily break the sealing member as a flexible material. Do.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 and 5 are a perspective view and a cross-sectional view showing the configuration of the toner leakage preventing sealing tape according to an embodiment of the present invention.

The toner leakage preventing sealing tape 10 according to an embodiment of the present invention is composed of a flexible sealing member 11 and an opening member 12 for breaking the sealing member 11 in the longitudinal direction. Sealing member 11 is a size that can be adhered to the sealing tape attachment portion (23a, 23b, 23c, 23d) is preferably easy to break in one direction of the longitudinal direction, as an example, a pulp may be employed.

The opening member 12 is composed of an attachment portion 12a attached to the lower surface of the sealing member 11 and an overlapping portion 12b exposed from the sealing member 11 and extending longer than the length of the attachment portion 12a. do. The length of the overlapping portion 12b extends upward from the attachment portion 12a at one end of the sealing member 11 so as to overlap the upper surface at one end of the sealing member 11, as shown by the solid line in FIG. In the folded state, the other end of the sealing member 11 has a length protruding to one side of the toner cartridge 20. In addition, the opening member 12 has a tensile strength such that the sealing member 11 can be broken in the longitudinal direction without pulling itself by breaking the protruding portion of the overlapping portion 12b in FIG. To be required. As the unsealing member 12, a lamination film or the like is suitable.

In addition, the attachment portion 12a of the opening member 12 is attached to the lower surface of the sealing member 11, and as shown in FIGS. 2 and 3, the sealing member 11 to which the opening member 12 is attached is toner. Although an adhesive may be used to adhere to the sealing tape attachment portions 23a, 23b, 23c, 23d around the supply opening 23, as shown in FIG. 5, the heat-sealing resin layers 16, 18 are at least a sealing member. The sealing member 11 can be easily opened by the sealing member 11 by means of heat-pressure fusion means such as a roller provided with a heat source, fusion means such as ultrasonic fusion means, etc. by forming on the lower surface of the 11 and the lower surface of the unsealing member 12. The sealing member 11 in which the opening member 12 is fused can be fused to the sealing tape attaching portions 23a, 23b, 23c, and 23d around the toner supply opening 23. Since heat-sealing resin layers 17 and 18 are formed on both sides of the unsealing member 12, fusion can be made more strongly between the unsealing member 12 and the sealing member 11, which is more preferable.

As described above, the toner leakage preventing sealing tape 10 having the opening member 12 adhered or fused to the lower surface of the sealing member 11 at the attachment portion 12a is toner as shown in FIGS. 2 and 3.

Fold and overlap the upper surface of the), and allow the protruding portion at its end to protrude from the toner cartridge 20, and then mount the toner supply roller. Thereafter, the toner chamber 21 is filled with toner through the toner filling stopper 22 to be transported, stored, or the like. In use, the projection 12 overlaps the overlapping portion 12b of the opening member 12 in the direction of the arrow in FIG. 3. When the part is pulled, the sealing member 11 is first peeled from the sealing tape attaching portion 23c while the sealing member 11 is joined at both sealing tape attaching portions 23a and 23b in FIG. 2. ) Is broken along the break line shown by the dashed chain line in FIG. 2 or FIG. 4. In addition, the sealing member 11 can be easily broken by adopting a material such as pulp which is easily broken in the longitudinal direction.

If the opening member 12 is pulled out continuously, the sealing member 11 is broken and removed at the break line as shown in Fig. 1, so that the toner supply opening 23 is opened, and the toner from the toner supply opening 23 is opened. The toner in the seal 21 is leaked out, and the outflowing toner is attached to the toner supply roller, thereby making the toner cartridge 20 usable. At this time, since the opening member 12 has a tensile strength sufficient to break the sealing member 11 in the longitudinal direction, there is no fear that the opening member 12 will be ruptured so that the toner supply opening 23 cannot be completely opened. do.

In this way, it can be easily opened without causing the opening failure simply by pulling the opening member 12, and furthermore, the sealing tape attaching portions 23a, 23b, because they are opened by breaking of the sealing member 11, 23c, 23d) can be strongly adhered, and furthermore, the toner leakage preventing sealing tape 10 can be attached easily and strongly by fusion.

In addition, the heat-sealing resin layers 16, 17, and 18 are formed so that the sealing tape attaching portions 23a, 23b, 23c, and 23d around the toner supply opening 23 can be more easily and powerfully by the heat-sealing means. It is possible to attach the toner leak-proof sealing tape 10, and also when the toner leak-proof sealing tape 10 is manufactured, the opening member 12 can be easily attached to the sealing member 11.

In particular, the structure is simple and inexpensive, and the recycling process is simplified and simplified compared to the conventional sliding type reinforced plastics in which an elastic member such as a sponge is attached at the time of recycling and a sealing is attached to the upper surface to open the sealed state. The cost is very affordable. That is, after dismantling the toner supply roller, the sealing tape attaching portions 23a, 23b, 23c, and 23d around the toner supply opening 23 are provided with the sealing member 11 in which the opening member 12 is easily fused by the fusion means. It is extremely easy and inexpensive to recycle the toner cartridge because it is fused, and the toner supply roller is mounted, and the toner is filled by toner through the toner filling stopper 22.
