[0005] An object of the present invention is to provide a compact crushing device that can be held by hand and shaken to powderize.

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

[0007] When seasonings such as coffee beans, tea leaves, grains, rock salt, pepper salt, sugar, and other ingredients, as well as the spheres, are placed in the container and the container is held by hand and shaken vigorously up and down or side to side, the ingredients are crushed between the spheres and the inner wall of the container inside the container and become powder.

[0008] When the container body is held by hand and vigorously shaken, the spheres move inside the container body, crushing the raw materials like a mortar; therefore, the container body and spheres are preferably made of a hard material. Therefore, examples of materials for the container body include ceramic and metal, but metal is preferred because of its ease of processing. Examples include copper alloys and steel. Furthermore, stainless steel has an effect similar to that of metal soap, and can be placed in the kitchen to eliminate the fishy odor of fish and other dishes. Here, the container body may be divided into multiple parts, and the crushing section that the spheres strike may be replaceable. For example, a cylindrical container may be divided into three parts, with a bottomed container-like crushing section at one end and a bottomed container-like crushing section at the other end. In this way, only the crushing section that the spheres strike may be made of metal, while the rest may be made of a light resin. The spheres should be hard and heavy, and preferably made of stone or metal; an example of a metal is an iron ball, which has a high specific gravity.

[0009] The number of spheres placed in the container may be one or more depending on the raw material. However, when grinding roasted coffee beans or the like to make coffee, the container may contain only one sphere, which facilitates removal and handling of the spheres and separation of the powder. The container may have a cylindrical section through which the spheres move and a grinding section against which the spheres abut. In this case, the powder may move through a gap between the inside of the cylindrical section through which the spheres move and the spheres. The upper and / or lower surfaces of the divided grinding section of the container may be formed concave. In this way, when the grinding section is removed from the container and the spheres are removed, the spheres can be placed on the concave upper surface.

[0010] The grinding device of the present invention allows users to obtain powder by placing raw materials and balls in the container and shaking it by hand, thereby making it possible to grind just the desired amount of powder. Shaking the grinding device allows users to enjoy the action of holding it in their hands and the sound it produces. More specifically, the grinding device can be freely swung by hand, allowing users to flexibly grind the materials by shaking it in any direction, such as vertically or horizontally, as well as by adjusting the strength and timing of the shaking while listening to the sound. This allows users to enjoy trial and error by adding various elements to obtain powder with the desired particle size distribution. Furthermore, the sound changes depending on the degree of grinding, allowing users to enjoy these changes. Conventional mills cause the powder to heat up, resulting in a loss of flavor. In contrast, the present invention uses a metal container body with excellent thermal conductivity, allowing the large surface area of ​​the container to absorb the heat generated during grinding of raw materials and also provides excellent heat dissipation. This reduces the impact of heat on the powder, preserving the flavor of, for example, coffee beans. Furthermore, dividing the container into multiple sections to allow the grinding section, where the balls come into contact, to be replaceable makes it easier to disassemble the container and perform maintenance, such as cleaning the grinding section. When the grinding part becomes worn, it is possible to replace only that part with a new one, or to select the surface shape of the grinding part according to the use of the raw material.

An example of the structure of Example 2 is shown. An example in which the container body is divided into three parts is shown. (a) shows the appearance, and (b) shows a cross-sectional view. Three examples (a), (b), and (c) are shown in which the shape of the grinding section is changed.

[0012] An example of the structure of a crushing device according to the present invention will be described below with reference to the drawings. Figure 1 shows an example of Example 1 in which a container body 10 is divided into two. The crushing device 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 placed therein.

[0013] In this example, the first container 11 and the second container 12 are made of brass (brass alloy). The first container 11 has a convex portion 11a formed on the opening side, and the second container 12 has a concave portion 12a formed on the opening side, allowing them to fit together. However, the convex portion 11a may have a male thread and the concave portion may have a female thread, allowing them to be threaded together. Furthermore, the first container 11 and the second container 12 have symmetrical external shapes, and flat portions are formed on the top and bottom surfaces 12d and 11d, allowing them to stand on their own with either the top surface 12d or the bottom surface 11d at the bottom. As shown in FIG. 2(b), the first container 11 and the second container 12 each have a cylindrical moving portion consisting of cylindrical portions 11b and 12b, and crushing portions 11c and 12c on the inner bottom side against which the spheres 20 strike during shaking. In this example, the spheres 20 are made of cast iron.

[0014] As shown in Figures 3(a) and 3(b), the spheres 20 and raw materials 1, such as coffee beans, are placed in the first container 11, the container is then covered with the second container 12, and the container is vigorously shaken up and down as shown in Figures 4(a) to 4(c). When holding the container 10 with both hands and shaking it vigorously up and down and left and right, the spheres 20 move through the cylindrical sections 11b and 12b inside the container, crushing the raw materials in the upper and lower grinding sections 11c and 12c. The spheres 20 make a sound when they hit the upper and lower grinding sections 11c and 12c, which can be enjoyed. Therefore, it can also be enjoyed as a musical instrument, so to speak.

[0015] In this embodiment, as shown in FIG. 4, the outer diameter D of the sphere 20 is set so that the coffee beans, when crushed into powder, can pass through the gap between the cylindrical portions 11b and 12b of the container body 10 and the sphere 20. １ and the inner diameter D of the cylindrical portions 11b and 12b ２ This is an example of setting the outer diameter D １ and inner diameter D ２By setting the above, the particle size of the powder to be pulverized can be adjusted. The raw material 1 may be placed in both the first container 11 and the second container 12. Also, as in Example 2 shown in FIG. 5, the sphere 20 may be elliptical like a rugby ball, elongated in the axial direction of the cylindrical portion 11b, or a flat portion 21 may be provided on the side so that the sphere 20 moves along the cylindrical portion 11b without rotating. This allows the surface where the sphere 20 strikes the raw material 1 to be uniform, and the surface can be made uneven. Furthermore, by providing multiple holes through which the powder 2 can pass and lids to cover them in one or both of the upper and lower crushing portions 11c and 12c, the crushed powder can be removed directly after crushing.

[0016] When coffee beans are used as the raw material to make powdered coffee, you can enjoy the taste of freshly ground coffee while enjoying your shake.

[0017] FIG. 6 shows Example 3, in which the container body 10 is divided into three parts. A cylindrical third container is provided between a bottomed first container 11 and a bottomed second container 12, allowing the container to be disassembled into three parts. The first container 11 and the second container 12 function as crushing units. In Example 3, one of the first container 11 and the third container 13 is fitted or screwed together, and the other of the second container 12 and the third container 13 is fitted or screwed together. Crushing units 11c and 12c are formed at the bottoms of the first container 11 and the second container 12, against which the spheres 20 abut. The first container 11 and the second container 12 may have the same structure or may have different depths. Example 3 is made of stainless steel, and the upper and lower surfaces 12d and 11d are flat or concave with a slight recess in the center, allowing the container to be shaken vigorously by supporting the upper and lower surfaces 12d and 11c with hands. In particular, if the upper surface 12d and / or the lower surface 11d are formed concave, fingers are less likely to slip and shaking can be performed more vigorously. For example, if the upper surface 12d of the second container 12 shown in FIG. 6 is concave, after grinding the raw materials, the second container 12, which also functions as a lid, can be removed from the container body 10 and placed on a table or the like, and the spheres 20 removed from the container body 10 can be stably placed on the concave portion of the upper surface 12d. This also has the advantage of being easily placed on a table or the like by inverting. Alternatively, the first container 11 and the second container 12 may be made of stainless steel, and the third container 13 may be made of resin. The stainless steel container body 10 has an effect similar to that of so-called metal soap and also has a deodorizing effect.

[0018] FIG. 7 shows examples of variously changed shapes of the crushing section. (a) shows an example of crushing section 112c made of a conical recessed shape. (b) shows an example of crushing section 212c with a flat bottom surface. (c) shows an example of crushing section 312c with multiple protrusions or grooves formed on the bottom surface. By varying the shape of the crushing section in this way, it is possible to select the shape according to the raw material to be crushed and the particle size. In addition, the crushing section can be replaced when worn, and by dividing it into three parts, maintenance of the crushing section is easy.

[0019] The grinding device according to the present invention is compact and can grind various raw materials into powder by shaking it by hand.
