(Industrial Application Field) The present invention relates to a powder container used in a powder measuring device or the like. (Prior Art) As an example of a powder weighing device for measuring powder with high precision, the present applicants previously filed an application for a weighing device whose configuration is shown in FIG. 5. (Japanese Patent Application No. 62-142928) In the example shown in FIG. 25 is a measuring container, 26 is a measuring device, 27 is a driving device, 28 is a connecting portion, and 29 is a control portion. In the measuring device configured as described above, the vibration of the drive device 27 moves the powder 30 inside the container body 21 to the powder supply port 2.
When the weight measured by the weighing device 26 reaches a predetermined value, the control section 29 stops the vibration of the drive device 27 and starts weighing. I'm trying to finish it. This measuring device includes a container main body 21 for supplying powder.
Since the lid part main body 22 and feeder part 23 are removably connected to the drive device 27 by the connecting part 28, these parts can be replaced integrally even when using many types of powder, and there is no need to worry about the gap between powders. It has the feature that measurements can be carried out without contamination. (Problem to be solved by the invention) However, in the conventional weighing device described above,
Depending on the powder to be weighed, static electricity generated on the powder particles due to vibration may cause the feeder section 23 to
A part of the powder supplied into the measuring container 25 from the tip of the feeder part 23 as shown at 30a in FIG.
There was a problem in that the powder was attracted to the lower end of the powder and fell onto the weighing device 26 outside the weighing container 25, making it impossible to accurately measure the weight of the powder in the weighing container 25. In addition, depending on the powder to be measured, vibrations may generate coarse particles inside the container body 21, and the coarse particles may clog the powder supply port 24, making it impossible to supply the powder. . An object of the present invention is to solve the above-mentioned problems and provide a powder container that can accurately supply powder of any type. (Means for Solving the Problems) The powder container of the present invention includes a container body for storing powder, a lid body for supplying the powder to a measuring device, and a powder supply port in the lid body. In a powder container used in a weighing device having a structure that integrally includes a lid consisting of a feeder portion provided through the feeder portion, a protrusion portion provided at the tip of the feeder portion and a jammer provided integrally with the lid portion main body. It is characterized by comprising a board. (Function) In the above-mentioned configuration, by providing a protrusion at the tip of the feeder section, static electricity is generated in the powder particles, and even under a charged state, a predetermined amount of powder can be prevented from going around from the tip of the feeder section. Since it can be fed into a weighing container, accurate measurement of powder weight can be carried out. In addition, by providing a jammer plate on the lid body of the powder container, coarse particles generated inside the powder container will not clog the powder container supply port, and the jammer plate itself will not be clogged. Smooth powder supply is possible without any interruption in powder supply. (Example) FIG. 1 is a sectional view showing the structure of an example of a powder container of the present invention. In FIG. 1, the powder container 1 is
It is constructed by engaging a container body 2 for containing powder 8 with a lid 5 consisting of a lid body 3 and a feeder portion 4. The lid main body 3 and the feeder section 4 are
It is integrally formed through the powder supply port 6.
Further, at the tip of the feeder portion 4 of the lid 5, which has a V-shaped cross section, there is a protrusion 7 as shown in a perspective view in FIG.
are provided integrally. Thereby, it is possible to prevent the powder 8 from moving around to the outside of the feeder section 4 due to static electricity. That is, since the powder 8 that moves through the feeder section 4 due to vibration can be supplied downward along the protrusion 7, the influence of static electricity can be completely eliminated. Note that the lid main body 3 is provided with a connecting portion 9 for connecting with a drive device (not shown). Further, as a means for removing coarse particles, by providing a jammer plate 14 as shown in the plan view in FIG. Through the feeder section 4
It is designed to reach up to. Therefore, in this embodiment, the coarse particles 13 can be effectively removed, and the powder can be weighed with high accuracy. FIGS. 3a and 3b are views showing modified examples of the feeder section 4 in the powder container of the present invention, respectively. Third
In the embodiment shown in FIG. a, by providing a protective cover 10 over the entire upper opening of the feeder section 4 and the end face excluding the powder outlet section, the powder 8 charged with static electricity is prevented from going around to the outside of the feeder section 4. can be even better prevented. In the embodiment shown in FIG. 3b, a shutter 11 is provided in the center of the feeder section 4, and the opening degree of the shutter 11 is narrowed for samples with high specific gravity, and the opening degree of the shutter 11 is narrowed for samples with low specific gravity. By widening the width, the flow of powder on the feeder section 4 can be appropriately adjusted, which is effective for precision metering. Hereinafter, an example of actual measurement using the powder container of the present invention will be described. After adjusting the various raw materials shown in Table 1 to a particle size of 150 μm or less,
For powder samples dried at 105℃ for more than 2 hours,
Using the powder container shown in FIG. 1, the powder was measured using the measuring device shown in FIG. The results are shown in Table 1.

[Table] Depending on the type of kaolin, clay, and talc,
When using a known powder container, accurate measurement is not possible due to the powder going around to the bottom of the feeder, but from the results in Table 1, regardless of whether the powder is easily charged with static electricity or not, various types of powder This shows that body raw materials can be measured accurately. Similarly, Table 2 shows the results of repeated measurements for carbon and lithium borate.

[Table] From the results in Table 2, it can be seen that repeated weighing can be performed satisfactorily. (Effects of the Invention) As is clear from the above results, according to the powder container of the present invention, by providing a protrusion on the feeder part and a jammer plate, it is possible to prevent the powder from going around due to static electricity, Since it is possible to prevent unstable powder supply due to particles, it can be used in conjunction with conventional weighing devices to achieve highly accurate weighing.
