Description

[Technical field]

[0001] The present invention relates to a grinding tool for grinding various raw materials into powder, and more particularly to a grinding tool that can grind raw materials into powder by shaking by hand. [Background technology]

[0002] In recent years, personal memorial services have become popular as a way of honoring the deceased. In this case, the remains may be placed in a small urn and kept nearby, such as on a Buddhist altar, or stored as bone powder in a decorative container.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-169734 Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a compact grinding device that can be used to grind ingredients into powder by simply holding it in the hand and shaking it. [Means for solving the problem]

[0006] The grinding device of the present invention has a container body to be held and shaken by hand, and spheres to be placed into the container body, and is characterized in that the spheres and raw materials are placed into the container body and shaken by hand, causing the raw materials to become powder.

[0007] The raw materials, such as remains, and the spheres are placed into the container, which is then held in the hand and shaken vigorously up and down or side to side. Inside the container, the raw materials are crushed between the spheres and the inner wall of the container, turning them into powder.

[0008] When the container is held in the hand and vigorously shaken, the spheres move inside the container and crush the raw materials like a mortar, so it is preferable that the container and the spheres are made of a hard material. Therefore, examples of the material for the container include ceramics and metals, with metals being preferred in terms of ease of processing. For example, copper alloys, steel, etc. The sphere should be hard and heavy, preferably made of stone or metal; an example of a metal would be an iron ball, which has a high specific gravity.

[0009] The number of spheres put into the container may be one or more than two depending on the raw materials. In order to make it easy to remove and handle the spheres and separate the powder, the container body may have only one sphere and have a cylindrical section inside through which the sphere moves and a crushing section against which the sphere hits. In this case, the powder may move through a gap between the spheres and the inside of the cylindrical portion through which the spheres move. Effect of the Invention

[0010] The grinding device of the present invention can produce powder by simply putting the raw materials and spheres into the container and shaking it by hand, so that only the required amount of powder can be produced. More specifically, the grinding tool can be swung freely by hand, and not only can it be swung in any direction, such as vertically or horizontally, but it can also be flexibly ground while listening to the sound, including the strength and timing of the swing. Here, if a metal material is used as the material for the container body, the metal material has excellent thermal conductivity, so the container body, which has a large surface area, can absorb the heat generated when the raw materials are crushed, and also has excellent heat dissipation properties.

[Diagram 5] 2 shows a structural example of the second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An example of the structure of a grinding device according to the present invention will now be described with reference to the drawings. As shown in FIG. 1, the crushing tool 100 is composed of a container body 10 consisting of a first container 11 and a second container 12, and a sphere 20 to be inserted therein.

[0013] In this embodiment, the first container 11 and the second container 12 are made of brass (brass alloy). In this example, a convex portion 11a is formed on the opening side of the first container 11 and a concave portion 12a is formed on the opening side of the second container 12, so that they fit together, but it is also possible to form a male threaded portion on the convex portion 11a side and a female threaded portion on the concave portion side so that they can be screwed together. In addition, the external shapes of the first container 11 and the second container 12 are symmetrical, and flat portions are formed on the upper surface 12d and the lower surface 11d, making it possible for the container to stand on its own with either the upper surface 12d or the lower surface 11d as the lower end. As shown in FIG. 2(b), the first container 11 and the second container 12 each have a cylindrical moving section consisting of cylindrical sections 11b and 12b, and a crushing section 11c and 12c on the inner bottom side against which the sphere 20 hits when shaking. In this embodiment, the sphere 20 is made of cast iron. There are no limitations on the structure as long as the container 10 has a cylindrical section in which the spheres 20 move and a crushing section at the top (ceiling) or bottom (bottom) inside the container 10.

[0014] As shown in Figs. 3(a) and (b), spheres 20 and raw material 1 are placed in first container 11, which is then covered with second container 12 and vigorously shaken up and down as shown in Figs. 4(a) to (c). When container 10 is held with both hands and vigorously shaken up and down and left and right, spheres 21 move through cylindrical portions 11b, 12b inside the container, and move so as to crush the raw materials in upper and lower crushing portions 11c, 12c. When the ball 20 hits the upper and lower crushing sections 11c and 12c, a sound is generated.

[0015] In this embodiment, as shown in Figure 4, the outer diameter D1 of the sphere 20 and the inner diameter D2 of the cylindrical portions 11b, 12b are set so that the raw materials pass through the gap between the sphere 20 and the cylindrical portions 11b, 12b of the container body 10 when they are ground into powder. The particle size of the powder to be pulverized can be adjusted by setting the outer diameter D1 and the inner diameter D2. The raw material 1 may be placed in both the first container 11 and the second container 12. Furthermore, as in Example 2 shown in Figure 5, sphere 20 may be made elliptical like a rugby ball that is long in the axial direction of cylindrical portion 11b, or a flat portion 21 may be provided on the side so that sphere 20 moves along cylindrical portion 11b without rotating. This makes it possible to make the surface where the sphere 20 strikes the raw material 1 constant and to provide the surface with irregularities.

[0016] If you select bone as the raw material, it will be crushed into bone powder, and you can keep the crushing tool as an urn. Furthermore, the raw material is not limited to bone, and various raw materials can be used as long as the purpose is to make powder. [Explanation of symbols]
