Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a developer supply container used for supplying a developer to a developing device of an image forming apparatus such as an electrostatic copying machine or a printer.

[0002]

2. Description of the Related Art Conventionally, a powder toner is used as a developer in an image forming apparatus such as an electrostatic copying machine or a printer. The toner supply container is generally cylindrical or made of synthetic resin or the like. In many cases, the body such as a rectangular parallelepiped and the opening are integrally molded.

By the way, the toner supply container made of the above-mentioned synthetic resin or the like can smoothly perform the toner discharge work at the opening without polluting the surrounding area, and further, the developer supply container due to the impact during the transportation of the product or the toner exhaustion. Since high rigidity is required to withstand the shock during replacement, it is prepared by molding general engineering plastics such as ABS resin, high impact polystyrene resin (HIPS), polyurethane resin, polycarbonate resin, etc. ing.

Further, a developer supply container in which a container body is made of paper and plastic is joined to a molded flange portion by hot melt or the like has been proposed and commercialized.

Further, in the developer supply container, an opening which is generally opened for supplying the powder toner to the developing device is sealed by a seal member. The conventional seal is an easy peel type, and generally, the periphery of the opening of the main body is opened by peeling off the adhered portion of the film adhered by means such as an adhesive or heat sealing.

Further, the seal member has a tearing directionality and is narrower than the cover film and the cover film for sealing the opening of the container for supplying the developer, and the free end is pulled at the time of opening to tear the cover film and open it. A tear tape method for producing is also proposed.

[0007]

However, according to each of the above conventional examples, there are the following problems. In the above conventional example, the developer supply container body and the seal film are often made of plastic, and the following problems occur when the developer supply container is discarded after the toner is discharged. 1. When landfilling, the weight and volume are large, it takes time to incinerate after crashing, and the landfill becomes full soon. 2. When incinerated, toxic gas is generated when the plastic decomposes at high temperature. 3. When incinerated, the incineration temperature becomes high due to the combustion of plastic, and the durability of the incinerator is impaired.

[0008] Further, recently, global environmental problems have been greatly highlighted, and it goes without saying that the resources are wasted.
The problem of waste disposal has become a major issue. For example, it is difficult to secure a place to collect and store temporary waste because of its limited waste treatment capacity, and resource saving of petroleum energy required for incineration is required.

The seal film must be peeled off when the developer is replenished to the hopper of the image forming apparatus. However, when the film is peeled off, the developer scatters and the user's clothes, hands, etc. There was also the problem of getting dirty.

Further, in a developer supply container having a conventional seal film having a half-cut that does not need to be peeled off, the heat-sealed portion between the seal film and the container body is unsealed when the width of the container opening is large. There has been a problem that the width of the part becomes large and the opening strength becomes large.

A first object of the present invention is to solve the above problems, to facilitate disposal of a developer container when discarding it, and to reduce energy consumption during disposal.
An object is to provide a developer supply container that does not leak toner when replenishing toner.

When the toner is discharged to the main body, the end portion of the slide lid 7 is pulled as shown in FIG. 5, and the slide lid 7 is pulled out to a predetermined position. Then, the opening 8 for replenishment shown in FIG. 6 is fully opened, and the toner is discharged.

Therefore, toner may leak at the sliding portion of the slide lid 7, but in this embodiment, the foamed resin seal 4 is provided beside the sliding surface forming plate member 3 of the slide lid 7 as shown in FIG. It is installed. As shown in FIG. 7, the foamed resin seal 4 is formed by adhering a double-sided tape 10 to a urethane foam (maltoprene) 9 so that the double-sided tape 10 is adhered to the adhesive substrate surface 2 of the flange 3 ′. There is.

As described above, according to this embodiment, since the developer supply container is formed of paper material, when the container is discarded after the toner is discharged, the volume and weight are smaller than the plastic container, and the container is incinerated. , The heat energy equivalent to burning about half the weight of oil in a paper container is obtained. Further, the user can replenish the developer without soiling the hands / clothes.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The present embodiment is different from the first embodiment in that the foamed resin seal 4 is formed as an injection type. Also in this embodiment, as in the first embodiment, it is possible to satisfactorily fill and discharge the toner.

The foamed resin seal is formed by sending polyol and isocyanate in a predetermined distribution into the stirring chamber 30 shown in FIG.

No, and the incineration temperature is low. Furthermore, when incinerated, the thermal energy equivalent to burning petroleum of about 1/2 the weight of a paper container is obtained. Also, the user can replenish the developer without soiling his hands or clothes. In particular, since the present embodiment has the seal end suppressing plate, it is possible to prevent the situation where the seal material is simultaneously pulled out when the slide lid is pulled.

Even when the amount of protrusion of the seal was set to 2 mm, the same results as in this example were obtained.

<Fifth Embodiment> Next, a fifth embodiment of the present invention will be described with reference to FIG. The same parts as those of the first to fourth embodiments are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, the same urethane foam 9 as that used in the first embodiment is used as the foaming resin sealing member, and the fine powder 23 mainly containing fluororesin particles is applied to the surface of the urethane foam 9.

The method of attaching the foamed resin sealing member uses the sealing member end restraint plate as in the case of the fourth embodiment shown in FIG. However, the same configuration as that of the first embodiment shown in FIG. 1 may be used. In addition, the material and shape of the container body 1, the assembling method, the mechanism of the slide lid 7 and the like are the same as those in the first embodiment described with reference to FIGS. 2 to 6.

Also in this embodiment, as in Embodiments 1 to 4, when the container is discarded after the toner is discharged, the volume and weight are smaller than those of the plastic container, and a toxic gas is generated when the container is incinerated and discarded. No, and the incineration temperature is low. Furthermore, when incinerated, the thermal energy equivalent to burning petroleum of about 1/2 the weight of a paper container is obtained.

In particular, in this embodiment, since the fine powder mainly composed of the fluororesin particles is applied to the surface of the seal member, the sliding of the slide lid becomes smoother, and the seal material is pulled out at the same time when the slide lid is pulled. Can be prevented.

<Sixth Embodiment> Next, a sixth embodiment of the present invention will be described with reference to FIG. The same parts as those of the first to fifth embodiments are designated by the same reference numerals and the description thereof will be omitted.

In this example, instead of the urethane foam of Example 5, an injection type resin foam seal 21 was used as in Example 2. The foamed resin seal 21 has the second embodiment.
Similarly to the above, in addition to the polyol and the isocyanate, a small amount of a silicone rubber-based material was added in order to provide the sliding property, and the same method and conditions as in Example 2 were used. The other structure of the flange portion is the same as that of the fifth embodiment.

In the present embodiment, the foamed resin as described above is injected into the seal portion of the container flange portion to foam, and the seal member end restraint plate 40 is bonded as shown in FIG. Next, after placing the slide lid 7 at a predetermined position, the reinforcing flange 12 is combined with the container flange and bonded. The foamed resin seal is not limited to the urethane type and may be a silicone rubber type polypropylene type or the like.

Also in this embodiment, the same effect as in Embodiment 5 was obtained.

<Seventh Embodiment> Next, a seventh embodiment of the present invention will be described. The same parts as those of the first to sixth embodiments are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, the slide surface forming plate of the slide lid 7 has the same shape as that of the third embodiment, as shown in FIG. 9, and the other conditions are the same as those of the sixth embodiment. did. The results were the same as in Example 5.

<Embodiment 8> Next, an embodiment 8 of the present invention will be described. The same parts as those of the first to sixth embodiments are designated by the same reference numerals and the description thereof will be omitted.

Comparative Example 1 Next, Comparative Example 1 for comparison with the above Examples 1 to 8 will be described. In this comparative example, a container body and a flange portion as shown in FIG. 2 were produced by molding engineering plastic, and a sealing film was used as a sealing member. That is, a seal film is heat-sealed, toner is filled from a filling port, and a cap is fitted to a container for toner replenishment at a position where an opening portion of a container body flange is formed.

When such a container was filled with toner, discharged, and discarded, both volume and weight were larger than those in Examples 1 to 4, and a toxic gas was generated when discarded by incineration. Furthermore, the incineration temperature is 100 ° C. as compared with this example.
It is higher than the above, and the load on the incinerator is very large. Therefore, environmental problems cannot be dealt with.

Further, when the seal film was pulled out, the developer powder was also scattered, the hands were soiled, and the clothes were attached to clothes. Furthermore, although it is reusable, it is difficult to reuse it by using this container because the resin is melted when the sealed portion is seen. The melted portion had to be scraped off smoothly and with good dimensional accuracy, and new heat sealing had to be performed, which caused a considerable increase in cost, and therefore it was considered that reuse is inappropriate.

<Comparative Example 2> Next, Example 4 and Example 5
A comparative example 2 for comparison with will be described. This comparative example has substantially the same structure as that of the fourth and fifth embodiments, but the seal end pressing plate 40 is not in the positional relationship of pressing the foamed seal, strengthens the flange at the end, and slides the slide. Those with a structure whose role is only to regulate the position were evaluated.

In this case, the foam sealing material was adhered on the adhesive base surface of the seal, but when the slide lid was pulled and the seal was opened, there was a feeling that the seal material slightly floated from the adhesive base surface. Further, the force required to pull the slide lid was slightly larger than that in Example 4.

<Ninth Embodiment> Next, a ninth embodiment of the present invention will be described with reference to FIGS. In addition, Example 1
