Description

[Technical Field]

[0001] In the field of grinding tools for grinding various food ingredients such as roasted coffee beans, tea leaves, or grains into powder, grinding tools that can be enjoyed by shaking them by hand have been developed. The present invention is a grinding tool spoon used to remove the powder from such grinding tools. [Background technology]

[0002] For example, roasted coffee beans can be ground immediately before use in a coffee mill to obtain fresher, tastier coffee. In the case of tea, it is also known to grind tea leaves into powder. In order to obtain a delicious beverage, there has been a demand for a filter to remove and filter the powder from the grinding device just before drinking, or a convenient spoon to transfer the powder directly into a drinking container. During this process, powder may adhere to the grinding tool, and it is desirable to remove it completely. The reason is that the remaining powder may corrode or oxidize when used again after a while, which can cause problems such as impairing the flavor of the drink.

[0003] Patent Document 1 clearly shows an application brush on the end of the spoon in Figure 8 of the document, but the brush in this document is a brush for applying to sushi, etc., and is not for sweeping away crushed material adhering to the threads, etc. In addition, the shape of the spoon is bulky compared to the handle, so it is not possible to efficiently sweep away crushed material adhering to the side using the longitudinal side of the spoon handle as in the present invention. Patent Document 2 clearly shows a toothbrush with a handle end shaped like a small spoon, but this is merely a representation of the shape and is not actually used as a spoon.

[0004] [Patent Document 1] Utility Model Registration No. 3134154 [Patent Document 2] Actual opening 1972-21871 Summary of the Invention [Problem to be solved by the invention]

[0005] As shown in Figures 1 to 4, a grinding device has been developed that has a container body and spheres to be placed in the container body, and the spheres and raw materials are placed in the container body and shaken by hand to turn the raw materials into powder. When removing the powder of the pulverized material from the container, the container is often detachably connected, and the powder of the pulverized material tends to accumulate in the gaps. In particular, if the container is connected with a screw shape, the powder of the pulverized material tends to stick to the fine threads, which hinders removal. Furthermore, when the container has a cylindrical internal shape as shown in Figures 1 to 4, the powder of the pulverized material is removed by inverting the container, and the powder of the pulverized material tends to stick to the periphery of the cylindrical part inside the cylinder. There was a need for a spoon that could easily remove the powder from crushed materials and also cleanly take out the powder from crushed materials. [Means for solving the problem]

[0006] The spoon for crushing tool is characterized by having a brush for removing powder at the end of the spoon. A "powder removal brush" is a brush designed to remove powder.

[0007] For example, if raw materials such as coffee beans, tea leaves, grains, etc. and spheres are placed in the container of a grinding device such as that shown in Figure 1, and the device is held in the hand and shaken vigorously up and down or side to side, the raw materials will be crushed between the spheres and the inner wall of the container inside the container, turning them into powdered material.

[0008] When the container body of the grinding device is held by hand and shaken vigorously, the spheres move inside the container body and crush the raw materials like a mortar, so the powdered crushed material mentioned above may stick to the inside of the container body or get into the gaps in the joints of the container body. The problem can be solved by using a spoon to remove the powdered pulverized material that has stuck to the inside of the container and the powdered material that has gotten into the gaps in the joints of the container body at the same time, using a brush on the end of the spoon. The body of the crushing spoon is preferably made of metal, such as copper alloy or steel. Stainless steel is highly corrosion-resistant and convenient. Copper alloys and metals containing silver have a sterilizing effect and are hygienic. The brush material is preferably a soft material such as silicone rubber. If the brush is made of silicone rubber or is mainly made of silicone rubber, it is heat resistant and can be used conveniently for cleaning slightly hot pots or the inside of coffee bean roasting containers.

[0009] Furthermore, if the brush part is detachable, it is convenient to be able to select a brush of your choice in terms of color, bristles fineness, shape, softness, color, etc. In some cases, the detachable feature can be used to conveniently attach a spatula other than a brush, a hook for hanging, etc. Furthermore, although the brush is generally rod-shaped, a triangular, wavy brush is convenient for removing powder from the crushed material that has adhered to the threads of the crushing tool. Since the longitudinal side of the spoon is nearly straight, and the container body is often cylindrical, the powder of the crushed material adhering to the cylindrical, linear body part can be easily removed by simply turning it around, which is convenient since the longitudinal side part is nearly straight. [Effects of the Invention]

[0010] When using the spoon for crushing tools of the present invention, which is characterized by having a powder-removing brush attached to the end of the spoon, it is convenient because when extracting or scraping out the powder of crushed material, the powder of the crushed material adhering to the crushing tool can be easily removed with the powder-removing brush attached to the end of the spoon. If the powder removal brush is made of silicone rubber, it is environmentally friendly, heat resistant, and can be used for other purposes, making it convenient. The detachable brush for powder removal is convenient because it allows you to choose the brush of your choice depending on the color, bristles' fineness, shape, softness, color, etc. In particular, when the crushing tool has a threaded portion, a wavy triangular shape that fits perfectly to the shape of the thread is a preferable shape because it makes it easier to remove the powder from the crushed material at the threaded portion. The spoon is characterized by having a nearly straight longitudinal side surface, and since the container body is often cylindrical, the powder of the crushed material that adheres to the cylindrical, linear body part can be easily removed by simply turning it around, which is convenient since the longitudinal side surface is nearly straight.

[0012] First, before describing the present invention, an example of the structure of a crushing device will be described below with reference to the drawings. FIG. 1 shows an example in which the container body 10 is divided into two parts. 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, 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. (It is also possible to form a male thread on the convex portion 11a side and a female thread on the concave portion, 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, so that the containers can stand on their own with either the upper surface 12d or the lower surface 11d at the bottom. As shown in Figure 2(b), the first container 11 and the second container 12 have cylindrical moving parts consisting of cylindrical sections 11b and 12b inside, and crushing sections 11c and 12c on the inner bottom side against which the spheres 20 hit when shaking.

[0014] As shown in Figures 3(a) and (b), spheres 20 and raw materials 1 such as coffee beans are placed in a first container 11, which is then covered with a second container 12 and shaken vigorously up and down as shown in Figures 4(a) to (c). At this time, when the container body 10 is held with both hands and shaken vigorously up and down and left and right, the spheres 20 move in the cylindrical parts 11b and 12b inside the container body and move so as to crush the raw materials in the upper and lower crushing parts 11c and 12c.

[0015] As an example of a grinding device, as shown in Figure 4, the outer diameter D1 of the sphere 20 and the inner diameter D2 of the cylindrical portions 11b and 12b of the container body 10 are set so that the coffee beans, once ground into powder, pass through the gap between the cylindrical portions 11b and 12b of the container body 10 and the sphere 20. As described above, before explaining the present invention, specific examples of the crushing device to which the present invention is particularly applied have been explained.

[0016] 1 shows an embodiment of a spoon for a crushing tool of the present invention. Fig. 5 shows a front view of an embodiment of the crushing spoon of the present invention, Fig. 6 shows a right side view of the embodiment of the crushing spoon of the present invention, Fig. 7 shows a left side view of the embodiment of the crushing spoon of the present invention, Fig. 8 shows a back view of the embodiment of the crushing spoon of the present invention, Fig. 9 shows a plan view of the embodiment of the crushing spoon of the present invention, and Fig. 10 shows a bottom view of the embodiment of the crushing spoon of the present invention.

[0017] The spoon for a crushing tool of the present invention is particularly suitable for use as a crushing tool for crushing materials to obtain powder in the manner described above. The end of the spoon (upper part of the front view in Figure 5) is equipped with a rod-shaped brush for removing powder from crushed materials.

[0018] The spoon body is made of stainless steel. The brush for removing powder from crushed materials is made of silicone rubber and is removable. Of course, the shape of the brush is not limited to the rod shape shown in the figure, but can be any shape that makes it easy to remove powder from the screw part, such as a triangular wave shape.
