Description

The present invention relates to a grater.

A grater is a cooking utensil used to grate ingredients such as radish and ginger. The grater has a grating surface for sliding down the food material on its working part. A blade consisting of a plurality of sharp protrusions is provided on the grating surface. In addition to the blades, the grating surface may also be provided with a round hole for discharging the grated food.

When using a grater, hold the food to be grated in one hand and repeatedly slide the food back and forth in the longitudinal direction of the grated surface while applying pressure to the grated surface. Note that the direction parallel to the longitudinal direction of the grating surface and directed toward the distal end of the grater for the user is herein referred to as the "grating direction" or simply the "grating direction."

The grating surface of a normal grater is flat, and the blades on the grating surface are linearly aligned in a direction perpendicular to the grating direction.

Patent Document 1 describes a grater in which the cross-sectional shape of the grating surface perpendicular to the grating direction is curved downward.

When using the grater of Patent Document 1, the curved convex side of the grater is supported with the palm of the hand that does not hold the food. According to Patent Document 1, the pressing force on the grater can be received with the palm of the hand, and the pressing force is difficult to disperse, making it possible to grate stably.

Moreover, since the cross-sectional shape is curved downward, the rubbed down ingredients tend to naturally gather in the center of the curved part.

Registered utility model No. 3002081

However, since the grater described in Patent Document 1 has a shape in which the grating surface curves downward, it is not easy to sharpen the blade. Additionally, the size of the ingredients that can be rubbed down is limited. In addition, even if the food is of a suitable size at the beginning, when it is reduced in size by grinding, the blades on both sides of the grating surface become close to the hands, making it unsafe.

Further, the grater described in Patent Document 1 has a problem that it cannot be placed stably because the lower surface of the grater part is a curved convex surface. For example, when you want to apply pressing force to grate food, or when you want to reduce the burden on the handle, you may want to place at least a portion of the grater on a stand or the like. In such a case, there is a problem that a grater having a curved convex lower surface cannot be placed stably.

Furthermore, depending on the food, for example, it may be desirable to grate it in small circular motions. In such a case, it is preferable for the grated surface to be flat.

For the above reasons, a grater having a planar grating surface may be desirable.

However, conventional graters having a flat grating surface have a problem in that the grated foodstuff spreads. That is, the grated food is pushed by the reciprocating food and spreads to both sides of the grating surface and to the downstream end in the grating direction. Therefore, unless the operation is interrupted and the grated food is collected in the center and discharged to the downstream end, the grated food may spill from both sides of the grating surface. Further, there is also a problem that the grated food spreads at the downstream end in the grated direction, making it difficult to transfer to the container.

Furthermore, in conventional graters in which the blades are linearly arranged in a direction perpendicular to the grating direction, the food in the hand may slide sideways.

When the food is repeatedly slid down in a certain direction, grooves are created by the blade on the surface of the food. If grooves form on the surface of the food, the blade will no longer cut the food. Therefore, so that the blade can scrape the food, the food may be held at an angle to the groove, or the food may be intentionally rubbed at an angle to the direction perpendicular to the row of blades.

If the food material is held at an angle to the groove, the grinding work will be interrupted, and work efficiency will inevitably decrease. Furthermore, when the food is intentionally rubbed at an angle to the direction perpendicular to the blade row, it is necessary to slide the food down in the desired direction while preventing the food from sliding sideways parallel to the blade row. Food must be held firmly with great force. Since the grating surface has sharp blades, the food may slip from your hands, creating a safety issue.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a grater having a planar grating surface in which the grated foodstuffs are not dispersed but are naturally collected in the discharge section. Another object of the present invention is to provide a grater that can continuously grate food without changing the food.

The grater according to one aspect of the present invention includes, for example,
A grating surface for sliding down the food material is provided, and the grating surface is provided with a blade having a protruding tip, and the plurality of blades are arranged in a direction substantially perpendicular to the direction of sliding down the food material to form a blade row. The blade array is characterized in that it forms a convex linear shape on the downstream side in the direction of sliding down the food material.

A predetermined number of the blade rows may be arranged at predetermined intervals to form a blade group.
The plurality of blade groups may be separated by a separation zone, and a boundary portion that is concave or convex from the grating surface may be provided for each separation zone or each blade group.
The blade groups separated by the separation zone may have different blade shapes, sizes, orientations, or spacings, different distances between the blade rows, or different curvatures of the blade rows.

The grating surface may have a reservoir portion recessed from the grating surface at a downstream end in the grating direction of the food material.

The blade row may have a curved portion with a relatively large curvature in the center thereof.

The blade row may have a portion without blades.
The blade row may form a linear shape that is convex toward the upstream side, which is the direction opposite to the direction in which the food material is grated.

According to the present invention, it is possible to provide a grater having a planar grating surface where the grated foodstuff naturally collects in the discharge section without being dispersed. Further, according to the present invention, it is possible to provide a grater that can continuously grate food without changing the food.

Examples of embodiments of the present invention will be described below based on the drawings. Note that common constituent elements in the following embodiments may be given the same reference numerals and descriptions thereof may be omitted. In the description of the example embodiment of the present invention, in the sliding direction of the food material, the front side for the user is referred to as upstream, and the front end side is referred to as downstream.
<First embodiment>
FIG. 1 is a diagram showing an example of a grater 1 according to the first embodiment. As shown in FIG. 1, the grater 1 includes an action part 2 for sliding food down and a grater 1 is provided with a handle portion 3 for gripping the device. The action portion 2 is provided on the downstream side in the sliding direction of the food material, and the handle portion 3 is provided on the upstream side in the sliding direction of the food material.

The handle 3 includes a handle 4 and a locking hole 5. The handle 4 is plate-shaped in this embodiment. The handle 4 is not limited to a plate shape, and may have any shape as long as it is easy for the user to grasp during use. For example, the handle 4 may be rod-shaped. To make it easier for the user to grip, the handle 4 may have a non-slip material on its surface, such as elastomer resin. Furthermore, the handle 4 may be formed integrally with the action portion 2 or may be formed separately.

By providing the handle 3, the user can firmly grasp the grater 1 and use the grater 1 stably. Note that the handle 4 is not essential, and may not be provided.

The locking holes 5 are used when hanging the grater 1 on a wall. The locking holes 5 are convenient for cleaning the grater 1 and hanging it on a wall or the like to dry. Note that the locking hole 5 is preferably a through hole, but may have any shape. Moreover, the locking hole 5 can be omitted.

The handle 4 is connected to the grating surface 7 via the shoulder 6 of the action part 2. The action portion 2 includes a shoulder portion 6, a grating surface 7, a side edge portion 8, and a tip portion 9.

The action portion 2 is a plane, and its outer circumferential shape is arbitrary, and may be approximately rectangular or approximately trapezoidal as illustrated in FIG. 1 . In the example of FIG. 1, the action portion 2 is formed into a generally trapezoidal shape, with a narrow width on the upstream side and a width that gradually increases toward the distal end portion 9 on the downstream side. Since the action part 2 is formed into a roughly trapezoidal shape, the grating surface 7 becomes wider as it goes downstream, which is consistent with the fact that the sliding range of the food material expands somewhat from upstream to downstream. Suitable for work.

Although the material of the action part 2 is arbitrary, the action part 2 of this embodiment is made of metal. As the metal material, for example, a stainless steel plate or a copper plate can be used. The thickness of the metal working part 2 is not limited, and is, for example, 0.2 mm to 3 mm. If a sharpened blade is provided on a copper plate, it is preferably 1 mm to 2 mm. For example, the blade may be punched out of a stainless steel plate. When provided, the thickness can be, for example, 0.2 mm to 0.5 mm, preferably 0.2 mm to 0.4 mm. Note that a metal plate having partially different thicknesses may be used. Moreover, it does not have to be made of metal, and may be made of synthetic resin such as plastic resin or ceramics containing ceramic. In this case, the plate thickness may be, for example, 1 mm to 8 mm, preferably 2 mm to 6 mm.

The side edges 8 of the action part 2 have the functions of reinforcing the strength of the grating surface 7, preventing the grated food from spilling from both sides of the grating surface 7, and guiding the food downstream without spilling out sideways. It also has the function of guiding the grated ingredients to the downstream side. In order to fulfill these functions, the side edge portion 8 has a shape that is higher in rigidity than the grating surface 7 in the cross-sectional shape in the direction orthogonal to the sliding direction of the action portion 2 and protrudes toward the grating use side of the grating surface 7. It is on both ends.

When the grated surface 7 is made of a metal plate, the side edge portion 8 may be formed by folding the end of the metal plate so as to be convex toward the use side. By providing a folded portion of the metal plate at the end of the grated surface 7, the folded portion can support the grated surface 7 so that the grated surface 7 does not bend. Further, the folded portion of the metal plate can prevent the grated food from spilling. In addition, the grated ingredients accumulated on both ends of the grating surface 7 can be guided downstream.

The side edge portion 8 is not limited to being a folded portion of a metal plate. The side edge portion 8 may be made of, for example, a thick portion of the same material as the grated surface 7. For example, when the grating surface 7 is made of resin or ceramic, it may be made of a thick portion of the resin or ceramic. Further, the side edge portions 8 may consist of portions additionally provided at both ends of the grating surface 7. For example, it may be made of resin or the like which is additionally provided at both ends of the metal plate. Furthermore, the folded portion of the metal plate may be combined with resin or the like.

The tip 9 serves as a part for discharging the grated ingredients. The tip portion 9 may be the end portion of the plate material constituting the grated surface 7, or may be provided with another member such as resin. That is, it may be formed of or added with a non-slip material such as an elastomer resin so as not to slip when used against the edge or inside of a pot-shaped container such as a cooking bowl or bowl. Further, a supporting protrusion may be provided on the lower surface of the tip portion 9 (the surface opposite to the sliding surface).

The grating surface 7 is provided with a plurality of blades 10 each having a protruding tip. Here, the protruding tip refers to any upwardly pointed tip, and includes a conical tip, a polygonal pyramid tip, and a tip with an edge provided on a protrusion of any shape.

When the grating surface 7 is made of metal, the blade 10 can be formed by tapping a metal plate one by one with a hammer or the like using a chisel with a sharp tip.

When a plurality of blades 10 are present, the blades 10 may have a fixed shape, or may have different shapes, sizes, and orientations.

A plurality of blades 10 are arranged in a direction substantially perpendicular to the direction of sliding down the food material to form a blade row 11. Here, the term "direction substantially orthogonal to the sliding direction" means that, as will be described later, there are places where the blade row 11 is curved and is not perpendicular to the sliding direction locally, but when viewed as a whole, This means that the line formed by the blade row 11 is approximately perpendicular to the sliding direction.

In one blade row 11, the blades 10 may all have the same shape, size, and orientation, or may be different from each other. Further, within one blade row 11, blades 10 having a certain shape, size, and orientation may repeatedly appear at certain intervals or at varying intervals.

The blade row 11 of this embodiment forms a convex curve on the downstream side in the direction of sliding down the food material.

As shown in FIG. 1, a plurality of blade rows 11 are arranged at predetermined intervals to form a blade group 12. Here, "predetermined intervals" refers to cases where all the blade rows 11 are arranged at equal intervals, cases where the blade rows 11 are arranged at different intervals, and cases where the blade rows 11 are arranged repeatedly at varying intervals. Including cases where

The blade group 12 may have all blade rows 11 having blades 10 of a fixed shape, size, and orientation, or each blade row 11 may have blades 10 of a different shape, size, orientation, and spacing. Alternatively, each blade row 11 may have blades 10 of different shapes, sizes, and orientations.

In the example of FIG. 1, the blade group 12 includes blade rows 11 made up of blades 10 having different orientations, which are arranged alternately. Further, in the example of FIG. 1, the intervals between the blade rows 11 are also arranged so that long intervals and short intervals appear repeatedly.
Further, there is no through hole on the downstream side of the blade on the grating surface. In other words, there are no through holes immediately around the blade. If there is a through-hole in the middle of the grating surface, the grated food will get caught in the through-hole and it will be troublesome to remove it, and the water will flow off along the way, making it difficult to wash away the grated food and store it downstream. It fades. That is, in this embodiment, a flat grating surface is provided, a plurality of blades are lined up, and there is no through hole in the adjacent part of each blade, so that the grated food is washed away by the moisture released from the food. It is efficiently collected and discharged to the downstream discharge section.
According to this embodiment, since the blade row 11 forms a convex curve on the downstream side in the direction in which the food material is slid down, the food material (radish and its moisture) that has been rubbed down is moved as shown by the arrow in FIG. Then, the food concentrates in the center of the grated surface 7 and is discharged to the tip 9 in a mass due to gravity and the reciprocating movement of the food. This can prevent the grated food from spilling from both sides of the grating surface 7.

Here, the effect of the force of the blade row 11 forming a convex curve on the downstream side in the direction of sliding down the food will be explained using FIG. 2.

FIG. 2(a) shows the blades of a conventional grater in which the blades 10 are linearly arranged in a direction perpendicular to the grating direction, and FIG. The figure shows a curve forming a convex side.

In FIGS. 2(a) and 2(b), an arrow S indicates the direction in which the food material F is sifted down along the longitudinal center line of the grater.

Arrows M1 and M2 are parallel to each other and indicate directions inclined at a predetermined angle with respect to the direction S.

Although arrows M3 and M4 are parallel to each other, they indicate the sliding direction when the food material F is slid down at different locations on the left and right sides of the blade row 11.

Arrow M5 indicates the direction in which the food material F tends to slide sideways along the linear row of blades.

As described above, when the food material F is repeatedly slid down in a certain direction S, grooves are formed on the surface of the food material F by the blade 10. When a groove is formed on the surface of the food material F, the blade 10 no longer cuts the food material F and simply slides. Therefore, the food material F may be intentionally inclined with respect to the direction S so as to have an angle with the groove, and then slid down in the directions M1 and M2.

Directions M1 and M2 are parallel to each other, but as shown in FIG. The vehicle attempts to skid along a straight line in direction M5. Once the food material F begins to slide in the direction M5, grooves in that direction are easily formed on the surface of the food material F, and in order to maintain the direction M1 and slide down, the food material F must be firmly held and rubbed with force. I have to take it down.

On the other hand, as shown in FIG. 2(b), when the blade row 11 is convex toward the downstream side in the sliding direction, sideways sliding of the food material F is small. The reason is that the angle α2 formed by the intersection of the direction M2 and the blade row 11 is close to a right angle, and is smaller than the angle α1 formed by the intersection of the direction M1 and the straight blade row in FIG. 2(a). (α2<α1).

The closer the angle at which the food material F intersects the blade row 11 is to a right angle, the less the vector component of the force along the blade row 11 is, so the food material F is less likely to skid sideways. Since the food F has little tendency to skid, the holding force for the food F to prevent skidding is small.

Therefore, when the grater 1 according to the present embodiment slides down the food F by changing the direction, the food F can be firmly gripped with a small force, and the food F is less likely to slip out of the hand. Accordingly, the grater 1 of this embodiment is safer.

Moreover, according to the grater 1 of this embodiment, the density of the blades 10 that scrape the food material F is different between the direction M3 and the direction M4 in FIG. 2(b). That is, when the food material F is slid down along the direction M3, the food material F is rubbed at an angle with respect to the blade row 11, and the number of blades 10 that scrape the food material F increases, allowing the food material F to be scraped closely. .

On the other hand, when the food material F is slid down in the direction M4, the number of blades 10 that scrape the food material F is reduced, and the food material F can be scraped sparsely.

As described above, according to the present embodiment, it is easy to slide down the food material F by tilting the grater from the longitudinal center line, and the density of the blades 10 differs depending on the location of the grater, and these combinations Therefore, the grinding work can be carried out efficiently without changing the food material F.
<Second embodiment>
FIG. 3 is a diagram showing an example of the grater 1a according to the second embodiment. Hereinafter, parts common to those in the first embodiment may be denoted by the same reference numerals, and a description thereof may be omitted.

FIG. 3 shows an example in which the first blade group 14 is formed in the upstream region, the second blade group 15 is formed in the downstream region, and the separation zone 13 is provided between them. Of course, the arrangement is not limited to this. For example, blade groups other than the first blade group 14 and the second blade group 15 may be formed, or a plurality of separation zones 13 may be provided. good.

In the example of FIG. 3, the blade group 12 includes a first blade group 14 having relatively small blades 10 and a second blade group 15 having relatively large blades 10.

Since the blades 10 constituting the second blade group 15 are larger than the blades 10 constituting the first blade group 14, when the second blade group 15 on the downstream side is used for gating, relatively coarse grating can be achieved. .

The present embodiment is not limited to the above, and in short, blade groups of arbitrary properties may be formed in different regions. That is, the first blade group 14 and the second blade group 15 may be formed from a plurality of blades 10 having different shapes, sizes, directions, and intervals. Conversely, the first blade group 14 and the second blade group 15 may be formed from a plurality of blades 10 having the same shape, size, direction, and spacing.

Further, the intervals between the blade rows 11 forming the first blade group 14 and the second blade group 15 may be different from each other. Alternatively, the blade rows 11 forming the first blade group 14 and the second blade group 15 may have different curvatures.

In this embodiment as well, by arranging the blade rows 11 of the first blade group 14 and the second blade group 15 in a convex curved shape on the downstream side in the sliding direction, the force does not escape laterally during the sliding operation and is centered. This makes it easier to concentrate on tasks and allows for stable work.

Moreover, as shown by the arrow in FIG. 3, the grated food concentrates at the center of the grated surface 7a, and can be discharged to the tip 9 by gravity or the reciprocating food material.

In addition, in this embodiment, the first blade group 14 and the second blade group 15 are each formed by a total of six blade rows 11, with three rows of two adjacent blade rows 11. The number of blade rows 11 may be larger. For example, the number of adjacent blade rows may be different between the first blade group 14 and the second blade group 15, with three adjacent blade rows 11 each forming a total of nine blade rows. .

The separation zone 13 is provided in a direction substantially perpendicular to the direction in which the food material is rubbed down. The separation zone 13 is provided with a curved band-shaped convex boundary portion 20 . The boundary portion 20 has the function of separating the first blade group 14 and the second blade group 15, and the function of efficiently realizing the sliding operation beyond the boundary portion 20.

The function of separating the first blade group 14 and the second blade group 15 is to separate the separation zone 13 by using the first blade group 14 and the second blade group 15, respectively, when sliding down two types of foods. The boundary part 20 acts as a barrier, and the grated ingredients are not mixed.

The function that enables efficient sliding work beyond the boundary 20 is that when sliding, the convex boundary 20 catches the food a little, which accumulates force, and then jumps beyond the boundary 20. When descending to the grating surface 7, if there is a blade group (second blade group 15) at the position where the blade lands, the force is concentrated and the blade rushes into the blade group. This series of actions (referred to as a jump effect) can further improve the operability of the grated work.

In addition, although the boundary part 20 was made into the convex boundary part 20 here, the boundary part 20 may be a concave thing.

Further, the boundary portion 20 may be provided for each blade row 11 of the blade groups 14 and 15.
<Third embodiment>
FIG. 4 is a diagram showing an example of a grater 1b according to another embodiment. In the following, the same reference numerals will be used for the same parts as in the above-described embodiment, and the explanation thereof will be omitted, and the different parts will be explained.

The grater 1b shown in FIG. 4 is surrounded by side edges 8b to protect the outer periphery of the grating surface 7b. The side edge portion 8b is integrated with the handle portion 3 via the shoulder portion 6 to form a frame shape. The grating surface 7b and the side edge portion 8b may be formed integrally or may be formed separately. When the grating surface 7b and the side edge portion 8b are integrated, they are integrally molded from metal, synthetic resin such as plastic resin, or ceramic.

In this embodiment, the downstream end of the grating surface 7b is connected to the reservoir 16. The reservoir 16 is located on the downstream side of the grated surface 7b and is a recessed portion so as to temporarily store the grated food material.

A side recess 17 is provided at the joint between the grated surface 7b and the side edge 8b. The side recess 17 has a groove shape, and has a discharge port that continues to the reservoir 16.

According to the grater 1b of this embodiment, the grated food is naturally concentrated in the center of the grating surface 7b by the blade row 11 convex on the downstream side in the grating direction, and is accumulated by gravity and the reciprocating food. It is discharged to section 16. The grated food material pushed to both ends of the grating surface 7b is discharged into the side recess 17, and is discharged into the reservoir 16 through the side recess 17.

According to this embodiment, having the reservoir 16 is effective when there is no pot-shaped container or when pouring down a small amount of food.

In addition, since the grated food material flowing down through the center of the grating surface 7b and the grated food material flowing down through the side recesses 17 at both ends of the grating surface 7b are naturally separated into liquid and solid components, Suitable for separating liquid and solid content of grated food.

Note that the reservoir portion 16 may be integrally formed with the grating surface 7b, or may be attached by adhesive or the like using a known method. It may be provided in a removable manner.
<Fourth embodiment>
FIG. 5 is a diagram showing an example of a grater 1c according to another embodiment. In the following, parts common to those in the above-described embodiments will be given the same reference numerals and explanations will be omitted, and different parts will be explained.

In FIG. 5, the curvature of the blade row 11c on the grating surface 7c is different between both end portions and the center portion of the blade row 11c. Here, the central curved portion is referred to as the central curved portion 18, and the curved portions at both ends are referred to as the end side curved portions 19. In this embodiment, both the central curved portion 18 and the end curved portions 19 are curved convexly toward the downstream side in the sliding direction of the food material, and the central curved portion 18 has a relatively larger curvature than the end curved portions 19. It has become.

Since the blade row 11c as a whole is curved convexly toward the downstream side in the grating direction of the food material, the grated food material naturally concentrates in the center of the blade row 11c. Since the central curved portion 18 has a relatively larger curvature than the end curved portions 19, the grated food material is further concentrated in the pocket-shaped curved portion of the central curved portion 18.

One factor that causes grated ingredients to be discharged downstream is gravity. In other words, when the grated ingredients gather, they become clumps that are affected by gravity and are discharged downstream. Therefore, the grated ingredients concentrated in the pocket-shaped curved portion of the central curved portion 18 are naturally discharged downstream due to gravity. Furthermore, the grated ingredients gathered in the central curved portion 18 are easily pushed downstream by the reciprocating ingredients, and are also discharged downstream due to this.
<Fifth embodiment>
FIG. 6 is a diagram showing an example of a grater 1d according to another embodiment. In the following, parts common to those in the above-described embodiments will be given the same reference numerals and explanations will be omitted, and different parts will be explained.

In the grater 1d shown in FIG. 6, there is no central portion of the blade row 11d that is curved convexly toward the downstream side in the grating direction of the food material.

In this embodiment, since the blade row 11d as a whole is curved convexly toward the downstream side in the grating direction of the food material, the grated food material naturally gathers at the center of the blade row 11d. However, since the blade row 11d does not have a central portion to hold the grated ingredients, the grated ingredients concentrated in the center are naturally discharged to the downstream side.

In addition, in this embodiment, the blade row 11d has a structure in which there is no blade in the center part, but the part without a blade may be located in a part of the blade row 11d, and may be located on the left side or the right side. .

Furthermore, the central portion of the blade row 11d may have a linear shape with a different shape, and a portion thereof may be missing (in the example of FIG. 6, the central portion of the blade row 11d has a circular arc with a relatively large curvature). (It has a partially chipped shape.)
<Sixth embodiment>
FIG. 7 is a diagram showing an example of a grater 1e according to another embodiment. In the following, parts common to those in the above-described embodiments will be given the same reference numerals and explanations will be omitted, and different parts will be explained.

In FIG. 7, the blade rows 11e on the grating surface 7e are lined up in a convex curve toward the upstream side in the grating direction.

According to the blade row 11e of this embodiment, the grated food material easily flows to both ends of the blade row 11e due to gravity and the reciprocating food material.

Since side recesses 17 are provided at both ends of the blade row 11e, the grated food flows through the side recesses 17 and is discharged into the reservoir 16.
<Seventh embodiment>
FIG. 8 is a diagram showing an example of a grater 1f according to another embodiment. In the following, parts common to those in the above-described embodiments will be given the same reference numerals and explanations will be omitted, and different parts will be explained.

In FIG. 8, the blade row 11f on the grating surface 7f has a V-shape that is convex toward the upstream side in the grating direction.

Further, the first blade group 14f is formed in the upstream region, and the second blade group 15f is formed in the downstream region, and a separation zone 13f is provided between them in a direction substantially perpendicular to the direction in which the food material is rubbed down. The separation zone 13f is provided with a curved band-shaped convex boundary portion 20f. Of course, the arrangement is not limited to this, and for example, a group of blades, a separation zone, and a border may be further provided. In this embodiment, the first blade group 14f is formed by three adjacent blade rows 11f, and the second blade group 15f is formed by four adjacent blade rows 11f. However, it does not matter how many blade rows 11f are lined up.

Since the blade row 11f is V-shaped and dips diagonally toward both sides, the food material that has been slid down by the first blade group 14f either flows toward the side recess 17f or accumulates at one end at the boundary 20f. It flows from there toward the side recess 17f. The food material rubbed down by the second blade group 15f similarly flows toward the side recess 17f, or flows through the tip 9f into a bowl-shaped container for collecting the ground food material.

Note that although here, the boundary portion 20f is a convex boundary portion 20f from the lowering surface 7f, it may be a concave boundary portion 20f. Further, the boundary portion 20f may be provided for each blade group 14f, 15f.
<Eighth embodiment>
FIG. 9 is a diagram showing an example of a grater 1g according to another embodiment. In the following, parts common to those in the above-described embodiments will be given the same reference numerals and explanations will be omitted, and different parts will be explained.

In FIG. 9, like the blade row 11f of the grater 1f shown in FIG. 8, the blade row 11g has a V-shape so as to form a convexity toward the upstream side in the grating direction. Moreover, two adjacent rows of blade rows 11g and boundary portions 20g are arranged alternately.

While the grating surface 7f of the grater 1f shown in FIG. 8 is a flat surface, the grating surface 7g of the grater 1g of this embodiment has a longitudinally central portion curved in a convex shape toward the side that comes into contact with the food. (In other words, the central part in the longitudinal direction is raised).

According to this embodiment, since there are a plurality of boundary portions 20g on the grated surface 7g, the grated food material easily flows toward the side recessed portions 17g.

Furthermore, since the grated surface 7g is curved convexly toward the side that comes into contact with the food (that is, the user's side), the food grated on the grated surface 7g naturally flows into the side recesses 17g on both sides. It has a structure that allows it to flow easily.

Based on the above description, those skilled in the art may be able to imagine additional effects and various modifications of the present invention, but aspects of the present invention are not limited to the embodiments described above. Various additions, changes, and partial deletions are possible without departing from the conceptual idea and spirit of the present invention derived from the content defined in the claims and equivalents thereof.
