Description

Technical Field

[0001] The present invention relates to a scraping tool for scraping residual scrapings adhering to a large number of protrusions provided on a grater, and a method for manufacturing the same.

Background Art

[0002] When grating vegetables such as radishes and ginger or fruits such as apples, a grater (grating tool) having a large number of sharp protrusions provided on a plate-shaped main body may be used. However, when grating food ingredients such as vegetables and fruits with this grater, the grated food ingredients adhere in a state of being caught by the protrusions and are difficult to remove, causing trouble.

[0003] Conventionally, in order to collect the residue adhering to such protrusions, a collecting tool shown in Patent Document 1 has been proposed.

[0004] This collecting tool (hereinafter referred to as "conventional example") is provided with a collecting main body portion configured by bundling thin stainless steel wire rods in a rake shape at the tip of a gripping portion. Further, in the collecting main body portion, the tip of the thin stainless steel wire rod is bent at an obtuse angle downward obliquely to form a scraping portion. By moving the scraping portion at the tip so as to stroke the uneven portions such as graters, the fine food ingredients that have entered the uneven portions can be scraped out. Also, at that time, since the scraping portion is composed of a thin stainless steel wire rod, it can easily enter the uneven portions, and has excellent flexibility and high rigidity, so that the food ingredients can be efficiently scraped out.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, with conventional methods that use thin wires bundled together in a rake shape, if you try to scrape off the stuck residue with too much force, the wires will bend significantly, making it difficult to scrape effectively. Moreover, there is a risk that the wires may break and become permanently bent if too much force is applied.

[0007] In other words, conventional models, with their brush-like flexible scraping parts, are suitable for scraping a wide area with gentle force, but are unsuitable for scraping a specific area intensively with strong force.

[0008] This invention has been made in view of the current state of such conventional examples, and aims to provide a highly practical scraping tool and a method for manufacturing the same that can perform both tasks of scraping a wide area with soft force and tasks of scraping a specific area intensively with strong force.

[0023] A preferred embodiment of the present invention will be briefly described with reference to the drawings, illustrating the operation of the present invention.

[0024] In the present invention, when the tip of the scraping tool is pressed against the grater 20 with the convex side of the comb-shaped scraping section 4, which is formed in a concave curved shape at the tip, facing upwards, each scraping body 3 bends and deforms to spread outward in the width direction of the comb-shaped scraping section 4, becoming brush-like (brush-like) in a first scraping mode, allowing scraping over a wide area with soft force, as in the conventional example. In the second scraping mode, when the tip of the scraping tool is pressed against the grater 20 with the concave side of the comb-shaped scraping section 4 facing upwards, each scraping body 3 bends and deforms to converge towards the center in the width direction of the comb-shaped scraping section 4, causing the scraping bodies 3 to overlap at the center of the tip of the comb-shaped scraping section 4, forming a high-strength, deformation-resistant overlapping scraping body section 6. This overlapping scraping body section 6 allows for concentrated scraping of residue firmly attached to protrusions 21 that cannot be scraped in the first scraping mode, using strong force.

[0025] Thus, the scraping tool of the present invention is a highly practical scraping tool that can perform both tasks of scraping a wide area with soft force and tasks of scraping a specific area intensively with strong force. [Examples]

[0026] <Example 1> A specific embodiment of the present invention will be described with reference to Figures 1 to 7.

[0027] This embodiment is a scraping tool 7 for scraping off residual grated food adhering to a number of protrusions 21 provided on the surface of a grater 20, and consists of a gripping part 1 and a scraping body part 2 provided at the tip of the gripping part 1.

[0028] Specifically, the gripping portion 1 and the scraping body portion 2 are integrally molded from a single metal plate, and in this embodiment, a stainless steel plate, titanium plate, or titanium alloy plate with a thickness of 0.1 mm to 0.2 mm is used as the plate.

[0029] Furthermore, the gripping portion 1 and the scraping body portion 2 may be formed separately and then connected, and the materials are not limited to those described above. Any material that achieves the effects described in this embodiment later can be used as appropriate.

[0030] The components of this embodiment will be described in detail below.

[0031] As shown in Figure 1, the gripping portion 1 is made of a rectangular plate material that is curved in a concave shape in the width direction.

[0032] Specifically, the gripping part 1 is made of a rectangular plate material with a width of 15 mm to 20 mm and a length of 70 mm to 90 mm, which is curved in a concave shape in the width direction, and is configured to be gripped by placing the thumb on the curved surface and holding a writing instrument.

[0033] Furthermore, as shown in Figure 1, a hanging hole 8 is provided at the base end for suspending this embodiment from a hook or the like.

[0034] The material and shape of the gripping portion 1 are not limited to the above configuration and can be modified as appropriate.

[0035] Furthermore, as shown in Figure 1, the scraping body portion 2 is composed of a base end body portion 5 connected to the gripping portion 1 and a comb-shaped scraping portion 4 provided at the tip of the base end body portion 5.

[0036] As shown in Figure 2, the base end body portion 5 is formed in a roughly trapezoidal shape that gradually widens towards the tip, and is further formed in a concave, curved shape in the width direction.

[0037] Furthermore, the comb-shaped scraping section 4 consists of multiple flexible scraping bodies 3 arranged in the width direction, and, like the base end main body section 5, is formed in a shape that is concave in the width direction (concave curved shape when viewed from the tip).

[0038] Specifically, as shown in Figure 2(a), the comb-shaped scraping section 4 is configured such that the scraping bodies 3, which are formed in the shape of elongated plates, are arranged in the width direction at predetermined intervals. In this embodiment, the scraping bodies 3 are formed in the shape of elongated plates that are approximately 2 mm wide and 30 mm long and can bend and deform in the front-to-back direction, and the spacing between the arranged scraping bodies 3 is set to approximately 0.5 mm.

[0039] More specifically, as shown in Figure 2(b), the scratching body 3 located in the center in the width direction (hereinafter referred to as "central scratching body 3a") is installed in a horizontal position, and the other scratching bodies 3 are installed symmetrically in the width direction with respect to the central scratching body 3a, and are installed in a state of downward sloping toward the center in the width direction.

[0040] More specifically, as shown in Figure 2(b), in a predetermined range on the inner side in the width direction (towards the center) (in this embodiment, the range including the central scratching body 3a and the two scratching bodies 3 to its left and right), the scratching bodies 3 (including the central scratching body 3a) are set to different inclination angles (specifically, the inclination angle increases as you move outwards), and the line connecting the end faces is configured to form a roughly circular arc. The scratching bodies 3 further out in the width direction are set to a constant inclination angle, and the line connecting the end faces is configured to form a straight line, so that the comb-shaped scraping section 4 as a whole takes on an inverted V-shape.

[0041] Furthermore, the comb-shaped scraping portion 4 is not limited to the above, and may be configured to exhibit an arc shape or a bow shape (arc shape). In other words, in this embodiment, the concave curved shape means a shape that includes an inverted L shape, an arc shape, and a bow shape (arc shape).

[0042] Next, the manufacturing method of the scraping tool 7 according to the above embodiment will be described.

[0043] The manufacturing method for the scraping tool 7 according to this embodiment includes a base body forming step of forming a flat base body 10 having a gripping part forming part 11 that will become a gripping part 1 and a scraping body forming part 12 that will become a scraping body part 2 from a single metal plate material 15; a scratching body forming step of forming a scratching body forming part 13 that will become a scratching body 3 by providing a plurality of slits 14 in the width direction on the scraping body forming part 12 that extend from the tip toward the gripping part forming part 11 side; and a bending step of forming the scraping body forming part 12 into a tip-concave curved shape in which the center in the width direction is located lower than the ends in the width direction.

[0044] Specifically, as shown in Figure 3(a), first, in the base body forming process, a single stainless steel sheet (a titanium sheet or titanium alloy sheet may also be used) is punched and pressed to form a base body 10 in which the gripping portion forming portion 11 and the scraping body forming portion 12 are integrally formed. Note that the forming of the base body 10 is not limited to punching and pressing, and any appropriate means can be used.

[0045] Next, as shown in Figure 3(b), in the scratching body formation process, slits 14 are provided in the scratching body forming section 12 of the base body 10 by laser processing, and multiple scratching bodies 3 are formed by these slits 14.

[0046] Specifically, in this embodiment, slits 14 (gaps) with a width of 0.5 mm and a length of 30 mm are provided at 2 mm intervals along the width direction of the scraping body forming section 12.

[0047] Next, as shown in Figure 3(c), in the bending process, the base body 10 on which the scratched portion 13 is formed is shaped into a concave curved shape by press working.

[0048] Specifically, in this embodiment, the gripping portion forming portion 11 and the region of the scraping body forming portion 12 on the extension of the gripping portion forming portion 11 are bent using a mold of a predetermined shape (in this embodiment, a mold with a concave curvature radius of R30) so that they have the same curved shape. Through this bending process, the scraping body forming portion 12 is formed into an arc-shaped surface near the center in the width direction, where the central scratching body 3a located in the center in the width direction is horizontal, and the other scratching bodies 3 are inclined downward toward the center in the width direction. The outer sides in the width direction are formed into linear inclined surfaces, specifically linear inclined surfaces in which each scratching body 3 that is inclined downward toward the center in the width direction is continuous. Thus, a scraping tool 7 is formed, which consists of a gripping portion 1 and a scraping body portion 2 comprising a comb-shaped scraping portion 4 having a plurality of scratching bodies 3 and a base end body portion 5.

[0049] Furthermore, the manufacturing method of the scraping tool 7 in this embodiment is not limited to the method described above, and can be changed to any appropriate method (means) as long as the scraping tool 7 of this embodiment can be obtained.

[0050] Furthermore, the effects and advantages of this embodiment, configured as described above, will be explained below.

[0051] As shown in Figure 4, the scraping tool 7 of this embodiment, when the tip of the scraping body 3 is pressed against the grater 20 with the convex side of the comb-shaped scraping portion 4, which is formed in a concave curved shape at the tip, facing upwards, will bend and deform so that each scraping body 3 spreads outward in the width direction of the comb-shaped scraping portion 4, as shown in Figures 4 and 5, resulting in a first scraping mode in which a brush-like (brush-like) shape is formed. This allows scraping over a wide area with a soft force, as in the conventional example. Also, as shown in Figure 6, when the concave side of the comb-shaped scraping portion 4 is facing upwards, By pressing the tip of the scraper 3 against the grater 20, as shown in Figure 7, each scraper 3 bends and deforms so that it converges in the widthwise center of the comb-shaped scraping section 4, causing the scrapers 3 to overlap at the center of the tip of the comb-shaped scraping section 4, forming a second scraping mode in which a high-strength, deformation-resistant overlapping section 6 of scrapers is formed. This overlapping section 6 of scrapers can concentrate and scrape off residue firmly attached to the protrusions 21 that cannot be scraped off in the first scraping mode with great force.

[0052] Thus, the scraping tool 7 of this embodiment is a groundbreaking scraping tool 7 with unprecedented practicality, capable of performing both tasks: scraping a wide area with soft force and scraping a specific area intensively with strong force, all with a single tool 7.

[0053] <Example 2> A specific embodiment of the present invention, Part 2, will be described with reference to Figures 8 and 9.

[0054] This embodiment is a case in which the configuration of the gripping part 1 and the scraping body part 2 (comb-shaped scraping part 4) and the method of forming the scratching body 3 are different from those in Embodiment 1.

[0055] The differences from Example 1 will be described in detail below.

[0056] As shown in Figure 8, the gripping part 1 is a rectangular plate material that is the same width as the scraping body part 2 (approximately 35 mm) and slightly longer than the scraping body part 2 (approximately 50 mm), and is curved in a concave shape in the width direction, and is configured to be gripped by placing the thumb on the curved surface.

[0057] In other words, the overall shape of this embodiment is formed as a rectangle when viewed from above.

[0058] Furthermore, the comb-shaped scraping portion 4 that constitutes the scraping body portion 2 is directly connected to the tip of the gripping portion 1. In other words, in Embodiment 1, the scraping body portion 2 is composed of a comb-shaped scraping portion 4 and a base-end body portion 5, and the comb-shaped scraping portion 4 is connected to the gripping portion 1 via the base-end body portion 5. In contrast, in this embodiment, the scraping body portion 2 is composed only of the comb-shaped scraping portion 4 (without distinction between the base-end body portion 5 and the gripping portion 1), and the comb-shaped scraping portion 4 and the gripping portion 1 are directly connected.

[0059] Specifically, the comb-shaped scraping section 4 of this embodiment is configured such that the scraping bodies 3, which are formed in the shape of elongated plates, are arranged side by side in the width direction in a state where they are as close together as possible (gap: 0.1 mm or less).

[0060] In other words, in Embodiment 1, the comb-shaped scraping section 4 is configured such that the slits 14 between the scraping bodies 3 are so-called gaps with width, whereas in this embodiment, the comb-shaped scraping section 4 is configured such that the slits 14 between the scraping bodies 3 are so-called notches with no width, and the scraping bodies 3 are positioned as close together as possible.

[0061] The remaining configuration is the same as in Example 1.

[0062] Next, the manufacturing method of the scraping tool 7 according to the above embodiment will be described.

[0063] The manufacturing method for the scraping tool 7 according to this embodiment includes a base body forming step of forming a flat base body 10 having a gripping part forming part 11 that will become a gripping part 1 and a scraping body forming part 12 that will become a scraping body part 2 from a single metal plate material 15; a scratching body forming step of forming a scratching body forming part 13 that will become a scratching body 3 by providing a plurality of slits 14 in the width direction on the scraping body forming part 12 that extend from the tip toward the gripping part forming part 11 side; and a bending step of forming the scraping body forming part 12 into a tip-concave curved shape in which the center in the width direction is located lower than the ends in the width direction.

[0064] Specifically, as shown in Figure 9(a), first, in the base body forming process, a single stainless steel sheet (a titanium sheet or titanium alloy sheet may also be used) is punched and pressed to form a base body 10 in which the gripping portion forming portion 11 and the scraping body forming portion 12 are integrally formed. Note that the forming of the base body 10 is not limited to punching and pressing, and any appropriate means can be used.

[0065] Next, as shown in Figure 9(b), in the scratching body formation process, slits 14 (cuts) are made in the scratching body forming portion 12 of the base body 10 by shearing, and a plurality of scratching bodies 3 are formed by these slits 14.

[0066] Furthermore, in this scratch body formation process, the scratch body 3 formed by shearing is formed in a slightly inclined state, and an uneven portion 16 is formed at the base end of the slit 14. Therefore, in order to make the scratch body 3 horizontal and to eliminate the uneven portion 16 formed at the base end of the slit 14, a press process is performed to flatten the base body 10, as shown in Figure 9(c).

[0067] Next, as shown in Figure 9(d), in the bending process, the base body 10 on which the scratched portion 13 is formed is shaped into a concave curved shape by press working.

[0068] Specifically, in this embodiment, the gripping portion forming portion 11 and the region of the scraping body forming portion 12 that is on the extension of the gripping portion forming portion 11 are bent using a mold of a predetermined shape (in this embodiment, a mold with a concave curvature radius of R30).

[0069] The remaining manufacturing method is the same as in Example 1.

[0070] Furthermore, the effects and advantages of this embodiment, configured as described above, will be explained below.

[0071] In this embodiment, the scraping bodies 3 provided on the scraping body 2 (comb-shaped scraping section 4) are arranged side by side in a state where they are as close together as possible (almost no gap between them), so when not pressed against the grater 20, the scraping body 2 functions as a scooping section.

[0072] This allows the scraped-up remaining grated material to be scooped up directly with the scraping body 2 without the need to use a separate scooping tool.

[0073] Thus, in this embodiment, a scooping function is added to the scraping body 2, resulting in a more practical scraping tool.

[0074] It should be noted that the present invention is not limited to Examples 1 and 2, and the specific configuration of each constituent element can be designed as appropriate. [Explanation of Symbols]
