  However, when using a conventional butter knife to scrape the hard butter that has been stored in the refrigerator immediately after taking it out of the refrigerator, it is not easy to stably scrape the butter surface finely, and it is inevitably compared. There is a problem that the surface of the butter can be shaved only in the state of a large lump. In this case, it is not easy to apply a thin amount of butter to the surface of the toast after taking out an appropriate amount of butter with a butter knife while suppressing the intake (calories) of the butter. For this purpose, it is necessary to leave the butter in a hard and solid state immediately after being taken out of the refrigerator in a room or the like for a while and wait until the surface portion of the butter melts and becomes soft.

  Such a problem is also a problem that is valid even when a butter knife is used to scrape a hardened and hardened food such as cheese or chocolate that is stored in the refrigerator immediately after it is taken out from the refrigerator.

  This device has been made based on the recognition of the above problems, and its main purpose is to easily and surely make a few fine streaks of hard butter and other ingredients just taken out of the refrigerator. The object is to provide a butter knife that can be scraped off.

A butter knife according to the subject of the present invention is a butter knife main body extending along a longitudinal direction from one end to the other end, and fixed to the other end of the butter knife main body upward. A handle portion for gripping extending in an inclined manner, and a plurality of first grater blades arranged in sequence along the longitudinal direction, disposed on the upper surface of the butter knife main body portion and the lower surface facing the upper surface Each of the plurality of first grater blades is recessed from the upper surface in an orthogonal direction included in the upper surface in a direction orthogonal to the longitudinal direction and obliquely below the lower surface And a through hole that is continuously connected to an end surface of the protruding portion and penetrates the upper surface and the lower surface.

  According to the butter knife according to the subject of the present invention, the main body portion of the butter knife is brought into contact with the surface portion of the butter in a hard mass just taken out of the refrigerator, and then in the direction orthogonal to the longitudinal direction. The end surface of the projecting portion of each first grated blade portion bites into the surface portion of the butter, and the recessed upper surface of the projecting portion is The surface portion of the butter is cut out while moving in the orthogonal direction or the moving direction. Then, the surface portion of the butter that is scraped off in the orthogonal direction or the moving direction becomes a fine streak-like butter and is discharged from the corresponding through hole to the orthogonal direction or the moving direction from the next to the next. Is done.

As a result, the butter knife according to the subject of the present invention can easily and reliably have several streaky butters sliced into fluffy fine streaks rather than the hard butter that has just been removed from the refrigerator. It can be obtained by shaving, and the obtained several streaky butters can be spread thinly on the surface of bread such as toast as it is.

Moreover, several fine butter-like butters are scraped off from the hard butter surface portion, so that the butter to be applied to the bread can be easily melted, and the person ingests at that time The amount of butter can be reduced, thus reducing calories.

  Hereinafter, various embodiments of the present invention will be described in detail along with the effects and advantages based on the attached drawings.

(Embodiment 1)
<Configuration of butter knife 10>
FIG. 1 is a perspective view schematically showing an upper surface side configuration of a butter knife 10 according to the present embodiment. On the other hand, FIG. 2 is a side view schematically showing the configuration of the side surface side of the butter knife 10 when the butter knife 10 is viewed from the direction of the arrow AR1 shown in FIG. FIG. 3 is a plan view schematically showing the configuration of the upper surface side of the butter knife 10 when the butter knife 10 is viewed from the direction of the arrow AR2 shown in FIG. 4 schematically shows a partially enlarged configuration of the lower surface side of the butter knife body 1 when the butter knife body 1 of the butter knife 10 is viewed from the direction of the arrow AR3 shown in FIG. It is a rear view. Furthermore, (a) and (b) of FIG. 5 are longitudinal sectional views showing the longitudinal sectional configuration of the butter knife body 1 with respect to the disconnection LA-LB and the disconnection LC-LD shown in FIG. 3, respectively.

  As shown in FIGS. 1 to 3, the butter knife 10 is mainly composed of (1) a butter knife main body 1 and (2) a handle portion 2 for gripping the butter knife 10 by hand. Become. The butter knife 10 is made of, for example, stainless steel, and has a length of 16.5 cm, a width of 2.5 cm, and a height of 2.5 cm. Note that the material and dimensions of the butter knife 10 are not limited to the above-described examples of materials and dimensions.

  Among these, the butter knife main body 1 is a main part of the butter knife 10, and as will be described later, the part 1 is formed by changing the surface portion of the hard butter into several fine streaky butters according to the operation of the operator. Presents a slicing function for easy scraping. The butter knife main body 1 is a relatively flat surface portion having a relatively thin thickness T1 extending along the longitudinal direction DL from the one end 1ET toward the other end 1EP. For example, as an example, the thickness T1 is set to 0.6 mm. As shown in FIGS. 1 and 2, the one end 1ET of the butter knife body 1 is the tip of a smoothly curved convex portion. On the other hand, the other end portion 1 of the butter knife main body portion 1 is a rear end portion that is curved upward and inclined from the substantially flat central portion 1CP.

  On the other hand, the grip handle portion 2 is fixed to the back side portion of the other end portion 1EP of the butter knife main body portion 1 through various fixing methods such as spot welding or adhesion. And the handle | steering-wheel part 2 inclines and extends upwards, drawing the uneven | corrugated slope so that it can be easily grasped by the hand from the said connection part with the other end part 1EP. The inclination angle of the handle portion 2 is set larger than the inclination angle of a normal butter knife. By adopting such a handle design that is more inclined than usual, even if the butter is put in a butter case, the butter can be easily cut. From the viewpoint of improving the strength of the entire butter knife 10 while allowing the butter knife body 1 to exhibit the above slicing function (function to scrape fine streaky butter), the butter knife body 1 has an extremely thin thickness T1. The thickness T2 of the handle portion 2 is set to a sufficiently large value (T2 >> T1). For example, as an example, the thickness T2 is set to a value of 2.5 mm. By setting the thickness T2, a person can firmly hold the handle portion 2 when the butter knife 10 is used.

  In the above configuration, the butter knife 10 has a characteristic configuration in which a plurality of “butter knives” are arranged in the central portion 1CP of the butter knife main body 1 alternately in a line along the longitudinal direction DL at predetermined intervals. The structure of the “grated blade” (corresponding to the first and second grated blade portions 5 and 6) is provided.

  That is, first, as illustrated in FIGS. 1, 3, and 4, a plurality of first grated blade portions 5 that are sequentially arranged along the longitudinal direction DL are substantially line L <b> 1 corresponding to the center portion 1 </ b> CP. Accordingly, the upper surface 1US of the butter knife body 1 and the lower surface 1LS facing the upper surface 1US are disposed. In other words, as illustrated in FIG. 4, each of the plurality of first grated blade portions 5 is maintained at a predetermined interval d, and extends along the substantially center line L1 from the one end portion 1ET side to the other end portion. It is sequentially arranged in a row toward the 1EP side. As shown in FIGS. 3, 4, and 5 (a), each of the plurality of first grated blade portions 5 has (1) a protruding portion 4 and (2) a through hole 3.

Here, the protruding portion 4 is depressed (or sunk) from the upper surface 1US of the butter knife body 1 toward the orthogonal direction DR included in the upper surface 1US or the lower surface 1LS in the direction orthogonal to the longitudinal direction DL. And projecting from the lower surface 1LS while inclining obliquely downward of the lower surface 1LS. The shape of the protruding portion 4 is arbitrary. In this example, the upper surface 4RS of the protrusion 4 forms a surface (concave upper surface) that is recessed from the upper surface 1US in a concave shape in the orthogonal direction DR and downward. As shown in FIG. 4, in a plan view when the lower surface or back surface of the protrusion 4 is viewed from above in FIG. 4, the protrusion 4 has a bottom that is gently curved (corresponding to the end surface 4 ES). )), And the portion formed by intersecting the inclined side surfaces of the protrusion 4 forms a ridge line or edge 4E. The inclination angle formed between the ridgeline 4E inclined obliquely downward and the lower surface 1LS is an arbitrary angle θ. In this way, the shape of the protrusion 4 forms a “grating blade” that extends in the orthogonal direction DR and is recessed.

Due to the structure of the projecting portions 4 of each of the first grated blades 5, when the lower surface 1 LS of the butter knife body 1 is brought into contact with the hard butter surface and moved in the orthogonal direction DR, each projecting portion 4. Makes it possible to cut into the surface of the butter sharply and finely in a fine streak while moving in the orthogonal direction DR.

  Moreover, the through-hole 3 is continuously connected to the end surface 4ES of the corresponding protrusion 4, and penetrates the upper surface 1US and the lower surface 1LS of the butter knife main body 1. In this example, the through hole 3 has a substantially circular shape in a plan view when the through hole 3 is viewed from above in FIG. Due to the structure of the through-holes 3 of each of the first grated blades 5, each of the through-holes 3 when the lower surface 1 LS of the butter knife body 1 is brought into contact with the hard butter surface and moved in the orthogonal direction DR. Can exhibit a function of releasing fine streak-like butter that is scraped off by the protrusions 4 in conjunction with the corresponding protrusions 4.

  Second, as illustrated in FIGS. 1, 3, and 4, a plurality of second grated blade portions 6 are alternately arranged in parallel with the plurality of first grated blade portions 5, and The upper surface 1US and the lower surface 1LS are disposed along the longitudinal direction DL. That is, as illustrated in FIG. 4, each of the plurality of second grater blades 6 is predetermined on the side surface 1SS side of the butter knife main body 1 with respect to the substantially center line L1 while maintaining a predetermined distance d. Are sequentially arranged in a line from the one end 1ET side toward the other end 1EP side along the line L2 approaching at the interval d1. In addition, the plurality of second grated blade portions 6 and the plurality of first grated blade portions 5 are arranged in an alternately arranged state. Specifically, as illustrated in FIG. 4, the distance between the second grated blade portion 6 and the first grated blade portion 5 adjacent thereto is a distance d / 2 in the longitudinal direction DL. In other words, each of the second grated blade portions 6 is disposed at a position corresponding to the center position between the first grated blade portions 5 adjacent to each other. Therefore, with respect to the longitudinal direction DL, the first grated blade part 5 and the second grated blade part 6 are alternately arranged at an interval d / 2. As illustrated in FIGS. 3, 4, and 5 (b), each of the plurality of second grated blade parts 6 is also similar to each of the plurality of first grated blade parts 5. And a through hole 3 continuously connected to the protrusion 4. Therefore, the protrusion 4 and the through hole 3 of each second grated blade 6 also exhibit the same action as that of the protrusion 4 and the through hole 3 of each first grated blade 5 described above.

<Use and advantage of butter knife 10>
Consider a case where butter (corresponding to “butter body”) is placed in the refrigerator. In this case, the butter is cooled and hardened. Now, it is assumed that a person takes out the butter from the refrigerator, scrapes the surface portion of the butter using the butter knife 10, and spreads the shaved butter on the surface of the bread such as toast.

In this case, the person brings the lower surface 1LS of the butter knife main body 1 of the butter knife 10 into contact with the surface of the hard butter that has just been removed from the refrigerator, and then, as shown in FIGS. The butter knife body 1 is moved along the orthogonal direction DR shown. With such movement, the end surface 4ES of each protrusion 4 of the plurality of first grate blades 5 arranged in a line along the line L1 surely bites into the surface portion of the hard butter, and each protrusion 4 When the concave upper surface 4RS moves in the orthogonal direction DR and cuts the surface portion of the butter, the butter knife body portion 1 further cuts the surface portion of the butter according to the subsequent movement of the butter knife body 1 along the orthogonal direction DR. Go. And according to the continuous cutting operation | movement of the surface part of the hard butter by the protrusion part 4 accompanying the said movement, the through-hole 3 of each 1st grate blade part 5 changes the surface part of the said butter | batter continuously cut | disconnected. Continuous release to the outside. As a result, the surface portion of the butter shaved by each of the first grate blades 5 draws a trajectory BL shown as a thick dashed arrow in FIG. 5 (a) in accordance with the movement of the butter knife body 1 while In the direction of the orthogonal direction DR, it goes out to the outside as a fine streak-like butter. As a result of this action, the number of the first grated blades 5 is as small as the number of the first grated blades 5 from the through holes 3 of the plurality of first grated blades 5 according to the movement of the butter knife body 1 in the orthogonal direction DR. Streaked butter continues to be released to the outside in a state where they are connected.

Further, a plurality of second grated blade portions 6 arranged along the line L2 with respect to the plurality of first grated blade portions 5 in accordance with the movement of the butter knife main body portion 1 in the orthogonal direction DR are also plural. The same function as the first grated blade portion 5 is exhibited. As a result, in conjunction with the movement of the butter knife body 1, the surface portions of the hard butter continue to be scraped by the protrusions 4 of the plurality of second grated blades 6, and the plurality of second grated blades From the through-hole 3 of the part 6, as many fine streaky butters as the second grated blade part 6 are discharged to the outside in the direction of the orthogonal direction DR in a state where they are connected to each other.

  Moreover, since the thickness T1 of the butter knife body 1 is set to an extremely thin value as described above, the plurality of first grated blades 5 and the plurality of second grated blades 6 are formed by the corresponding protrusions 4. The surface portion of the hard butter that has been shaved can be continuously discharged from the corresponding through-hole 3 to the outside as a plurality of fine streaky butters in the direction of the orthogonal direction DR. I can do it. On the other hand, since the thickness T2 of the handle portion 2 is set to a value sufficiently thicker than the thickness T1 of the butter knife main body portion 1, a person presses with force while holding the handle portion 2 firmly. Thus, the butter knife main body 1 can be moved along the orthogonal direction DR on the surface of the hard butter while the projecting portions 4 are biting into the surface of the hard butter in a stable and reliable manner.

  With the movement of the butter knife body 1, the hard butter surface portion is arranged in a line at a center interval d / 2 as a trace of the surface portion being scraped by the protrusions 4. A plurality of thin streak-like grooves (corresponding to the total number of first and second grated blade portions 5 and 6) each extending along the orthogonal direction DR are formed.

  By the action of the first and second grated blades 5 and 6, the person uses the butter knife 10 to slice the fluffy fine streaks from the hard butter that has just been removed from the refrigerator. Several streaky butters can be easily and reliably shaved, and the obtained several streaky butters can be spread thinly on the surface of bread such as toast. In addition, it is possible to scrape several fine butter-like butter from the surface of the butter in a hard mass, so that the butter to be applied to the bread can be easily melted and ingested at that time. Can reduce the amount of butter that plays, thus reducing calories.

  Further, since the plurality of first grated blade portions 5 and the plurality of second grated blade portions 6 are alternately arranged in the longitudinal direction DL, the amount of the grated blade portions is increased by two steps, so that the butter knife main body is increased. By the movement of the person who moves the part 1, it becomes possible to easily scrape more fine streak-like butter from the surface portion of the hard butter.

  In addition to butter, the cheese or chocolate that is stored in the refrigerator in a hard state is also a few streaks that are sliced into fluffy fine streaks using a butter knife 10. Cheese or chocolate can be obtained as well. In that case, the person can utilize the obtained several streaky cheese or chocolate for cooking using cheese or for confectionery using chocolate.

<Modification>
In the first embodiment, the interval between the first grated blade portion 5 and the second grated blade portion 6 adjacent to each other in the longitudinal direction DL is set to the distance d / 2, but the interval is set to an arbitrary value. May be. That is, in general, each of the plurality of second grated blade portions is disposed at a position corresponding to the position between the first grated blade portions adjacent to each other among the plurality of first grated blade portions. Thereby, the first grated blade portion and the second grated blade portion are alternately arranged in the longitudinal direction.

  Moreover, the space | interval of adjacent 1st grated blade part among a some 1st grated blade part does not need to be equal respectively. That is, the interval between the adjacent first grated blade portions may be set to an arbitrary value. Similarly, the intervals between the adjacent second grated blades among the plurality of second grated blades may not be equal to each other.
