The present invention relates to a toner storage container and a toner storage product, which are toners for image development.
[0002]
[Prior art]
In recent years, a distribution system has been established in which used powder containers are collected by manufacturers, and the powder containers are refilled and shipped and distributed. Container components such as the container body are compatible with recycling. Accordingly, materials that are less likely to be deformed and damaged due to repeated use are becoming mainstream.
[0003]
In such a powder container, for example, as in the toner cartridge disclosed in Japanese Patent Laid-Open No. 6-208301, the powder supply to the apparatus is reliably and effectively performed and the purpose is to share parts with various apparatuses. As described above, there are some which are constituted by a plurality of members formed by forming constituent members such as a mounting portion to the apparatus and a powder supply unit separately from the container main body and attaching them to the container main body. The container having such a structure has strength and adhesion of the engaging portion so that the engaging portion and the fitting portion of the parts should not be mechanically weak or leak from the engaging portion of the powder. As a result of designing parts in consideration of the above, it is difficult to remove the engaging portion.
[0004]
By the way, when refilling the powder in the container at the manufacturer, it is possible to refill the powder through a process of cleanly cleaning the components including the container body so that the previous powder does not remain. is there. This is because, for example, the field of edible milling where strict hygiene management is performed, such as the kana powder supply cartridge of the automatic litter cake manufacturing apparatus and the powder supply cartridge of the automatic okonomiyaki manufacturing apparatus, and the field of electrophotographic toner cartridges where beautiful toner image quality is required. There is no time for enumeration.
[0005]
In such a field, it is required to disengage the member quickly and reliably, but the current container achieves a strong fitting at the time of manufacture and can be easily engaged for reasons of process shortening and cost reduction. There are not many containers that can be released. In addition, since these containers release the engagement by applying an excessive load to the constituent members when releasing the engagement, the deterioration is accelerated by the load locally applied to the members at the time of releasing the constituent members. The problem that is damaged is occurring. The breakage of the structural member due to the load applied when the member is disengaged hinders the recycling and deployment of the container.
[0006]
In addition, some containers are manufactured through a process such as sticking a seal member to a container opening in a state where the engagement member is temporarily fixed to the container body, but in such a container manufacturing method, the engagement member temporarily fixed It is preferable to be able to work in a state where it does not move freely, but it is necessary to specially order a tool that does not damage the container body or cause fatigue deterioration when the container body is pinched using a tool. Such a container could not be manufactured at low cost without making a large investment.
[0007]

[0037]
As shown in FIG. 2, a donut-shaped engagement member 2 is inserted into and engaged with a cylindrical tip portion 10 of a container body 1 of a powder container according to the present invention. 2, the holding means 31 of the fastening member 3 is fitted into the fastening member holding means 21 in the fastening member holding part 20 of the engaging member 2 to load the engaging member 2 into the container body 1. Engage with and integrate.
[0038]
FIG. 3 is a perspective view seen from the reverse direction of FIG. 2 and shows a state in which the engaging member 2 is integrated with the container body 1 using the fastening member 3. As is clear from FIG. 3, the fastening member 3 is inserted into the fastening member holding portion 20 of the engaging member 2 to be integrated with the container body 1.
[0039]
As shown in FIGS. 2 and 3, the engaging member 2 integrated with the container body 1 is provided with the end of the fastening member 3 inserted into the fastening member holding part 20 at the distal end part 10 of the container body 1. It fits into the groove 11 and is held by the cylindrical tip 10 with the groove 11 as a guide rail.

For example, it is possible to easily perform operations such as attaching a film-like sealing material to the opening 12 of the distal end portion 10 of the container body, surrounding the engaging member 2 and pasting the end portion of the sealing material. .
[0041]
Next, a method for holding the fastening member 3 according to the present invention will be described.
FIG. 4 shows a form of a fastening member having a plate shape which is one of the fastening members according to the present invention, and a fitting state of the fastening member.
[0042]
As shown in FIG. 4, the fastening member 3 according to the present invention has a plate-like shape and holds the holding means 31 </ b> A and 31 </ b> B for holding on the engaging member 2, and the fastening member 3 is attached to the engaging member 2. It has a notch 32 which is an urging means for urging the retaining member.
[0043]
As shown in FIGS. 4A and 4B, when attaching the fastening member 3 indicated by the broken line to the engaging member 2, the holding means 31 of the fastening member 3 is used as the fastening member holding portion of the engaging member 2. 20, and the holding means 31 on the side of the fastening member 3 is fitted and attached to the fastening member holding means 21 on the side of the engaging member in the biased state.
[0044]
The holding state formed by the fastening member holding means 21 on the engagement member 2 side and the holding means 31 of the fastening member 3 has a structure that continues to be maintained unless the biasing force from the fastening member 3 is released. The fastening member holding means 21 of the engaging member 2 and the holding means 31 of the fastening member 3 can continue to be held unless the urging force from the fastening member is released as described above, and can be recycled. There is no particular limitation as long as it has a structure. Specifically, when the holding means 31 on the fastening member side is a protrusion, the fastening member holding means 21 on the engagement member 2 side is used as a hole for fitting the protrusion, or when the holding means 31 is a hole, the holding member 31 is fitted into the hole. Examples include protrusions, or a rigid fibrous material such as a magic tape (R) on both sides, and the both fibrous materials are entangled to form a holding state.
[0045]
Although FIG. 4 shows a structure having two holding means on the fastening member, it is needless to say that the present invention is not limited to this, and the holding means can be regularly arranged on the fastening member surface, and The number of the fastening members is not limited as long as the strength of the fastening members is maintained and the recycling use is not hindered. In the fastening member 3 in FIG. 4, as shown in FIG. 4A, when the holding means 31 </ b> A is fitted to the fastening member holding means 21 on the engagement member side, a film-like seal is formed in the opening 12 as a temporary fastening state.

[0046]
The powder container according to the present invention achieves integration by engaging the engagement member 2 with the container body 1 via the fastening member 3, but when the urging force of the fastening member 3 is released. The fastening member 3 that has formed a strong fitting state can be easily removed from the fastening member holding portion 20, and the engagement portion 2 can be easily removed from the container body 1 by removing the fastening member 3. The container can be easily disassembled.
[0047]
Thus, since the powder container according to the present invention can be easily disassembled, it is possible to clean the used powder container in a state where each component is removed when recycling the used powder container. As a result, it is possible to reliably wash away the old powder to be removed from the components of the container, and solve the problem of impurity contamination in the powder as the container is recycled.
[0048]
Next, the resin material constituting the container according to the present invention will be described.
The resin material constituting the container according to the present invention is not particularly limited as long as it is a moldable thermoplastic resin, and specifically, polypropylene (PP), polyethylene (PE), ABS resin, high impact polystyrene. (HIPS) and the like are mentioned, but polypropylene, polyethylene, and high impact polystyrene are preferably used.
[0049]
Examples of the molding method for the container according to the present invention include an injection molding method and a hollow molding method, and the resins used in these molding methods include those described above. Not used, but especially when used as a toner container, not only the impact during transportation and impact during use, but also physical properties such as melt index and density so that they will not be damaged even after repeated use. It is preferable to use one having a value within a certain range.
[0050]
In the injection molding method, since resin is poured into the gaps of the mold, appropriate flow characteristics are required. For this reason, the value of the melt index is, for example, a resin material in the range of 1 to 30 g / 10 min like polypropylene, or the density is 0.94 to 0.97 g / cm like polyethylene. ^Three The resin material within the range is preferably used. If the melt index is smaller than this range, the flow characteristics will be poor and the mold will be filled unevenly, resulting in a problem that the outer wall of the container is uneven and the strength is insufficient, and the melt index is large. However, in any case, it becomes unsuitable for a container to be reused because the thermal stability is lowered and the storage characteristics are lowered.
[0051]
The hollow molding method is a method in which resin is flown out into a mold, compressed air is blown into the resin in a state of being sandwiched between molds, the resin is inflated so as to be in close contact with the mold, cooled and solidified to be molded. In this method, a resin material having a melt index value in the range of 0.1 to 4 g / 10 min like polypropylene, or a density of 0.94 to 0.97 g / cm like polyethylene. ^Three Good results are obtained when a resin material having a value in the range of is used. When the melt index is small, it is difficult for the molten resin to flow, so it is difficult to uniformly inflate at the stage of the inflating process with compressed air, the outer wall of the container becomes non-uniform, and the impact stability of the container decreases. Also, if the melt index is large, the outflow state becomes unstable because it is easy to flow, and the resin tends to accumulate at the lower end in particular.Therefore, the thickness changes at the upper and lower parts of the outer wall of the container, resulting in impact stability. Since the problem which falls is generated, in any case, it becomes unsuitable for the container which reuses.
[0052]
Moreover, in order not to be damaged when an impact is applied to the container body, the specific Izod impact value is preferably 0.1 to 30. When the Izod impact value is small, the Izod impact value is easily damaged by the impact, so that it is not suitable for a container for reuse. Further, if the Izod impact value is not less than a certain range, it can withstand a practical impact, that is, an impact force expected to be received by the container body in the trend of reuse, so it is sufficient to be within the above range.
[0053]
For example, in a high-density polyethylene that is an example that is preferably used as a resin material for a container body according to the present invention, the density is 0.94 to 0.97 g / cm. ^Three Has the value of The measuring method of density is measured based on JIS K7112. In particular, a measurement method using a pycnometer is a simple method.
[0054]
Specifically, a washed and dried pycnometer is prepared, and its mass is accurately measured. This is b (g). Next, the immersion liquid is filled exactly up to the marked line at a temperature of 23 ± 0.1 ° C., and its mass is measured accurately, and this is defined as e (g). Next, after the pycnometer is emptied and dried, about 1 to 5 g of a sample is put therein, the mass of the pycnometer is measured with the sample put in again, and the mass of the dried pycnometer is subtracted to obtain the sample mass. This is a (g). Next, the immersion liquid is added to the pycnometer containing the sample, and the sample is covered with the immersion liquid, and once put in a vacuum desiccator, the air in the immersion liquid is removed by reducing the pressure. Further, the immersion liquid is added up to the marked line at 23 ± 0.1 ° C. to the pycnometer from which the air in the immersion liquid has been removed, and the mass is measured. Let this be c (g). From this result, the density is determined according to the following calculation formula.
[0055]
Density (g / cm ^Three ) = {(A) / ((eb) − (ce))} × ρ
Here, ρ is the specific gravity of the immersion liquid at 23 ° C.
[0056]
For example, as for the physical properties of polypropylene, the density of polypropylene is 0.90 to 0.91 g / cm. ^Three Are preferred.
[0057]
The definition and measurement method of the Izod impact value are measured by the method described in JIS K 7110, and the definition and measurement method of the melt index are measured by the method described in JIS K 7210. The measurement is performed under the conditions of 230 ° C./2.16 kg for polypropylene and 190 ° C./2.16 kg for polyethylene.
[0058]
Although the outer wall thickness of the part which comprises the powder container which concerns on this invention is not specifically limited, From a viewpoint of maintaining durability, it is preferable that it is 1.0 mm or more. In addition, if the thickness of the outer wall is not uniform when an impact is applied, the brittleness appears. Therefore, the touch width of the thickness is 1.0 mm or less, preferably 0.5 mm or less. The width of this thickness indicates the difference between the average thickness and the minimum thickness. In addition, average thickness measures the thickness 10 places of the part except a bending part at random, and shows the average value. Further, the minimum thickness indicates a value at a location indicating the minimum value among the 10 locations.
[0059]
The powder container of the present invention is one in which the container is loaded into the apparatus and the powder stored in the container is replenished and supplied to the apparatus, and the powder stored in the container is not particularly limited. Specific examples include powder paints, food flours such as starch and kinako flour, cosmetics such as fortification, and various powder products such as lined lime. In addition to this, electrophotographic image formation It can also be preferably used as a container for the toner for developing an electrostatic image used in the above.
[0060]
