Description

  The present invention is a food cutter suitable mainly for cutting a lump of food such as butter commercially available for household use into small blocks, and in particular, food stored in a case such as butter. The present invention relates to a food cutter suitable for carving in a case.

  As a butter cutter for cutting butter into small blocks, for example, there is an invention described in Patent Document 1. This butter cutter is for cutting an entire lump of commercially available butter into many small blocks at once. For example, a small block of butter is placed on a hot cake for seasoning. However, in a small family, you do not eat many hot cakes at once, so if you cut the entire block of butter into many blocks, the butter blocks will remain. Then, since the surface area of the butter divided into blocks increases, the area that comes into contact with air increases, and when the remaining block of butter is stored, the quality deterioration due to oxidation of the butter is accelerated.

  Therefore, in order to cut as many blocks of butter as necessary, they are often cut by a butter knife. Butter knives are originally used to cut bread butter into small blocks and are used for convenience when cutting butter into small blocks, but butter knives cut butter into pieces. Is not the main purpose. The butter knife is provided with a spatula part in front of the handle, and cuts or scrapes the butter with the edge of the edge of the spatula part so that the butter is applied to the bread etc. on the surface of the spatula part. is there. The spatula portion is elongated and narrow, and is provided at the tip of the elongated handle so as to extend in the same direction as the handle. When cutting out butter, the butter to be cut out is relatively thin and can be cut out without resistance. Moreover, since the cut-out butter is applied immediately, the shape of the cut-out butter is not particularly considered. On the other hand, for example, when serving bread and butter to customers invited to home, a butter block cut into a square may be put out. In such a case, the butter stored in the butter case is put into a square block. It is necessary to divide into When cutting butter into blocks, the butter lump is cut with a relatively long blade edge, but the blade edge of the butter knife is not as sharp as a knife, and the cross-section of the blade edge is round. Therefore, the spatula portion receives a large resistance force at the time of cutting. Furthermore, since the hand holding the handle receives a moment due to the resistance force at the time of cutting, a heavy burden is placed on the hand, and the spatula portion is difficult to advance smoothly in the cutting direction. Further, many butter knives have a large round arc shape with the tip of the spatula not sharp. Therefore, when cutting the butter in the butter case, the tip of the spatula portion may not reach the corner where the peripheral wall and the bottom surface of the butter case intersect, and may not be cut completely.

  An object of this invention is to provide the food cutter suitable for carving food stored in a case like butter in the state put in the case.

The invention according to claim 1 has a plate-like blade portion in front of the handle, and the blade portion is bent in a V-shape with a central line extending in the longitudinal direction and an apex angle being substantially a right angle. Similarly, a straight blade edge bent in a V shape is formed on the front edge of the portion, and a plane formed by the blade edge is perpendicular to the longitudinal direction of the blade portion, and the blade bent in a V shape The blade component constituting the inclined surface of each of the blades has a side edge extending from the front end to a predetermined position on the handle side toward the handle side from the edge of the blade edge of each blade component component. A bulging portion bulged in an arc shape outside the line extending in the longitudinal direction of the portion is formed, the bulging portion is present in the front half portion of the blade portion, and the side edge in the latter half portion of the blade portion is By forming so as to gradually approach the top line from the predetermined position to the rear, each blade component part A structure that is recessed from the longitudinally extending line of the blade portion toward the handle side from the edge of the leading edge.

The invention according to claim 2 is a configuration in which at least one hole is formed in the blade portion , and the invention according to claim 3 is that the top line of the V-shaped blade portion crosses at least one hole. It is the composition which is.

The invention according to claim 4 is a configuration in which the blade portion is formed of a metal plate and is bent along a center line extending in the longitudinal direction of the blade portion.

The invention according to claim 5 is a configuration in which the blade portion and the handle are integrally formed of a metal plate and are bent along the center line in the longitudinal direction of the cutter.

In the first aspect of the present invention, the blade portion is bent in a V shape having a central line extending in the longitudinal direction and the apex angle is substantially a right angle, and the front edge of the blade portion is similarly bent in a V shape. A straight blade edge is formed, and the plane constituted by the blade edge is perpendicular to the longitudinal direction of the blade, and the blade component constituting each inclined surface of the blade bent in a V shape is From the front end to a predetermined position on the handle side, the side edge swells in an arc shape outside the line extending in the longitudinal direction of the blade portion from the edge of the blade edge of each blade portion constituting portion toward the handle side. An extended bulge is formed, the bulge is present in the front half of the blade, and the side edge in the latter half of the blade is gradually approaching the top line from the predetermined position to the rear. By forming the blade from the edge of the blade edge of each blade portion component toward the handle It is recessed from the longitudinally extending line. Therefore, when the cutting edge is applied to the upper surface of the food in the case placed on the table and the food is cut, the handle located above the blade is pushed straight down together with the hand holding it. It will be. Then, the axis of the force applied to the cutter from the hand and the axis of the reaction force received from the food are almost the same.Unlike a general butter knife, the hand holding the handle receives a moment due to the resistance force during cutting. Therefore, a large burden on the hand does not occur. The blade edge has the same V shape as that of the cross section of the blade portion, and the apex angle of the V shape is substantially a right angle. Thereby, as will be described in detail later, a rectangular parallelepiped food such as butter can be easily cut into small blocks having any thickness.

In the invention according to claim 2, at least one hole is formed in the blade portion. Accordingly, since the contact area between the food and the surface of the blade portion is reduced when the food is cut, the resistance received from the food can be reduced. In addition, it is possible to make it difficult for the cut food to adhere to the blade portion. According to a third aspect of the present invention, the top line of the V-shaped blade portion traverses at least one hole. That is, the hole is not formed only in the flat plate portion, but is formed across the bent portion of the plate. If the hole is formed on a flat plate, butter may be clogged and difficult to remove when cutting butter, etc., but if the hole is formed so as to straddle the bent part, It is hard to clog the hole, and it can be easily removed even if clogged.

Since the blade part is formed of a metal plate and is bent along the center line extending in the longitudinal direction of the blade part, the invention can be easily manufactured by pressing or the like.

  In the invention according to claim 5, since the blade portion and the handle are integrally formed of a metal plate and bent along the center line in the longitudinal direction of the cutter, the blade portion and the handle can be easily formed by a single press or the like. Can be manufactured. Further, since the handle is bent, it is difficult to bend, and when the fingertip is placed on the inner concave surface bent during use, the fingertip fits the concave surface and is difficult to slide.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The butter cutter 1 is integrally formed of a single stainless steel plate. The butter cutter 1 has a blade portion 3 having a V-shaped cross section in front of the handle 2, and the apex angle of the V shape is substantially a right angle. The boundary between the handle 2 and the blade portion 3 is a line BB in FIG. The blade portion 3 is formed by bending a stainless steel plate into a V-shaped cross section, and is composed of two planar blade portion constituting portions 5 and 6 having a top line 4 connecting the V-shaped top portions as boundaries. The blade 3 is symmetric with respect to the top line 4. Cutting edge 7, 8 is formed at the front edge of each blade component 5, 6. The blade edges 7 and 8 are formed before the stainless steel plate is bent into a V shape, so that the blade edges 7 and 8 that are perpendicular to each other by being bent are continuous. As shown in FIG. 13, which is a shape before the butter cutter 1 is bent and before the blade is attached, the front end edge 12 of the blade portion 3 to be bladed as the blade edge of the butter cutter 1 before the bending is the butter cutter 1. It is perpendicular to the front-rear direction. Therefore, the plane formed by the blade edges 7 and 8 that are bladed and bent is perpendicular to the longitudinal direction of the butter cutter 1. As a result, when the butter put in the butter case is separated, when the butter cutter 1 is lowered vertically with the handle 2 and the blade edges 7 and 8 reach the bottom of the butter case, All of them touch the bottom of the butter case at the same time, and part of the blade edges 7 and 8 do not float from the bottom, so that the butter is not left uncut.

  A hole 9 is formed in the blade portion 3. The hole 9 is formed symmetrically with respect to the top line 4 of the blade portion 3 having a V-shaped cross section. As shown in FIG. 13, the hole 9 is formed to be relatively wide. The ratio of the length of the hole 9 in the front-rear direction to the length of the blade part 3 in the front-rear direction is about 60%. However, the ratio is not limited to this value and may be 50% or more, or 70%. Further, the width of the blade 9 is gradually reduced as it goes from the front part to the rear part corresponding to the fact that the horizontal part is gradually reduced from the front part to the rear part. By providing the hole 9, as shown in FIG. 1, the narrow portions 10 and 11 having the same length as the length in the front-rear direction of the hole 9 are provided between the side edges 13 and 14 of the blade portion 3 and the hole 9, respectively. Is formed. As described above, according to the present invention, butter can be applied on the surfaces of the blade component parts 5 and 6 that form a right angle. In that case, if it paints mainly using the narrow parts 10 and 11, the butter adhering to the surface of the narrow parts 10 and 11 is left like the spatula part formed in the comparatively narrow width of the normal butter knife. You can apply butter without it. This is because the narrow portions 10 and 11 are literally as narrow as the butter knife spatula. However, when the lateral width of the hole 9 is very narrow like a slit, since the narrow part is not formed in the blade part 3, the effect of providing such a hole is small. In FIG. 13, the lateral width of the hole 9 on the vertical line with respect to the front-rear direction of the butter cutter 1 is preferably 20% to 60% of the lateral width of the blade portion 3 on the vertical line. However, since the width of the portion close to the handle 2 of the blade portion 3 is narrow, if the ratio of the width of the hole is 50% or more in such a narrow portion, the width of the narrow portions 10 and 11 in that portion becomes too narrow. In such a case, it is necessary to make the strength smaller than 50%.

FIG. 4 is a side view of the blade portion constituting portion 6 when the surface thereof is viewed facing forward, that is, when the blade portion constituting portion 6 is set up vertically and the other blade portion constituting portion 5 is made horizontal. . As can be understood from this figure, a bulging portion 27 is formed that bulges in an arc shape outward from a line 26 extending in the longitudinal direction of the blade portion from the edge of the blade edge of the blade portion constituting portion toward the handle side. ing. That is , the side edge 14 of the blade portion 3 is formed as a convex arcuate bulging edge 17 that bulges outward from the front end 16 from the front end 16 to a predetermined position 15 on the handle side. It is formed so as to approach the center line in the front-rear direction of the butter cutter 1 while gradually forming a smooth arc shape from the rear to the rear. Thus, when butter is applied to the bread with the blade component 6, the arcuate bulging edge 17 first strikes the surface of the bread and shifts it to apply butter so that the blade 3 moves smoothly. . If there is no arcuate bulging edge 17 and the side edge 14 gradually approaches the top line 4 as it goes backward from its front end 16, the front end 16 of the side edge 14 first hits the surface of the bread when applying butter. Since the angular front end 16 moves so as to scratch the surface of the bread, the blade portion 3 cannot be moved smoothly.

  As described above, the butter cutter 1 of the present embodiment is integrally formed from a single stainless steel plate. In the manufacturing method, first, a stainless steel plate is punched into a shape shown in FIG. At that time, the hole 9 of the blade portion 3 and the hole 18 of the handle 2 are simultaneously punched out. Next, the front edge 12 of the blade 3 is bladed and the blade 3 and the outer edge of the handle 2 are deburred. Further, as shown in FIG. 8, if the cross sections of the side edges 13 and 14 of the blade portion 3 are rounded, butter can be smoothly applied like a butter knife. In the next step, the stainless steel plate is pressed and bent so that the cross-sectional shape of the blade portion 3 forms a right-angled V shape. At the same time, the handle 2 is bent. As shown in FIGS. 9 to 12, the handle 2 is bent so that its cross section forms an arc, and the radius of curvature of the cross section is the smallest near the boundary between the handle 2 and the blade portion 3. Gradually grows as you go to the edge. Since the stainless steel plate has the smallest width in the vicinity of the boundary between the handle 2 and the blade portion 3, the bending stiffness is small and it is easy to bend. In addition, since the radius of curvature of the cross section of the wide portion of the handle 2 is large, when the fingertip is placed on the concave surface of the wide portion, the fingertip is familiar with the concave surface and is easy to use.

  Next, an example of how to use the present invention will be described with reference to FIGS. This method of use is a method of separating three blocks from the butter 20 in the butter case 19 having a width that is substantially the same as the maximum width of the blade portion constituting portion 6 and a thickness that is approximately one third of the maximum width. . First, as shown in FIG. 5, the butter cutter 1 is held so that the butter cutter 1 is perpendicular to the butter upper surface, and the blade portion constituting portion 6 enters the gap between the butter 20 and the end wall 23 of the butter case 19. The butter cutter 1 is placed at a position along the outer surface of the blade and the blade portion constituting portion 5 can be inserted into the butter 20 with the notch 22 shown in FIG. Next, the butter cutter 1 is lowered vertically and a cut 22 is made in the butter 20. Next, as shown in FIG. 6, the blade portion constituting portion 6 enters the gap between the butter 20 and the side wall 24 of the butter case 19 and extends along the outer surface of the butter 20, and the blade portion constituting portion 5 is the length of the notch 22. The butter cutter 1 is placed at a position where the first block 21 can be cut with a thickness of one third. Next, the butter cutter 1 is lowered vertically to cut the first block 21 from the butter 20. Next, as shown in FIG. 7, the blade component portion 6 enters the gap between the butter 20 and the side wall 24 of the butter case 19 and extends along the outer surface of the butter 20, and the blade component portion 5 is the length of the notch 22. The butter cutter 1 is placed at a position where the second block 25 can be cut with a thickness of one third. Next, the butter cutter 1 is lowered vertically to cut the second block 25 from the butter 20. Next, when cutting out the third block, if the butter cutter 1 is moved from the state of FIG. 7 to the position where the end of the blade portion constituting portion 5 and the end of the notch 22 are in contact, the remaining third block Blocks can be cut out. In this method, since the blade component 6 that does not perform the cutting action is along the outer surface of the butter 20, the blade component 5 that is perpendicular to the blade component 6 is also perpendicular to the outer surface of the butter 20. The cutting line and the cutting line to the butter 20 are not inclined, and the block can be an accurate rectangular parallelepiped. Further, in this method, only the blade portion constituting portion 5 cuts the butter 20 and cuts the blocks 21 and 25, and the other blade portion constituting portion 6 does not cut the butter. Therefore, compared with the case where the butter is cut using both of the blade constituent parts 5 and 6, the resistance that the butter cutter 1 receives from the butter is halved, so that the butter can be easily separated. The above is an example of the usage method of the present invention, but a great number of usage methods can be conceived depending on the idea of the user.

  Next, the size of this embodiment will be described. The size is the size of the butter cutter 1 shown in FIG. The total length of the butter cutter 1 is about 140 mm, and the maximum width is about 51 mm. The length of the hole 9 is about 30 mm and the maximum width is about 21 mm. The length of the front edge 12 is about 47 mm, which is 4 mm shorter than the maximum width of the butter cutter 1. The plate thickness of the butter cutter 1 is 1.2 mm, but preferably 0.5 mm to 2 mm. Although the size is as described above, it is needless to say that the present invention is not limited to these numerical values.

  In addition, this invention can take a various aspect based on the structure mentioned above. The butter cutter 1 may be a metal other than a stainless steel plate, such as aluminum or copper. Moreover, materials other than metal may be used, for example, plastic injection molding or hard wood produced by grinding. The hole 9 may not be symmetric with respect to the top line 4. In order to make it difficult for butter or the like to adhere to the surface of the blade portion 3, the surface of the blade portion may be processed with a fluororesin or a large number of minute irregularities may be provided. The handle 2 and the blade portion 3 may be formed separately and combined. Alternatively, the handle 2 may be formed in a slightly flat spherical shape that is large enough to fit in the hand with plastic or wood. In this way, when the butter cutter 1 is erected and lowered vertically to cut out the butter, it is easy to cut down because it is easy to apply a downward force using the palm.

The butter contained in the butter case can be cut into rectangular parallelepiped blocks by dropping a blade portion having a V-shaped cross-section with a blade edge at the front end edge and a vertical angle of approximately 90 degrees perpendicular to the butter.
