Description

  The present invention relates to a knife in which a plurality of recesses (recesses) for cutting a cut object are formed on a blade plate surface of a blade plate.

  In order to suppress the adsorption action that occurs between the cut piece and the blade plate surface cut during cutting, there are knives with holes formed in the blade plate or ribs formed. Not only is the processing difficult, but the hole edge must be sufficiently polished so as not to damage the operator's hand, making it cumbersome, difficult to clean, and sanitary.

  In addition, if the rib is not long to some extent, the effect does not appear, so that the rib repeatedly hits the finger attached to the cut object, often causing a sense of discomfort.

  Therefore, it is preferable to form a large number of recesses that suppress the adsorption effect on the blade plate surface, and to form a gap between the cut piece to be adsorbed during cutting and the blade plate surface to improve the separation. It can be said that this recess method cannot form a sufficient gap, and the separation is inferior to the perforated method.

  In other words, trying to make a large number of recesses so deep as to be close to the perforated method has a problem that the blade plate is not strong and the blade plate is not strong enough, and the recess can be deepened sufficiently. There wasn't. As a result, the recess method is not sufficiently separated from each other, and each method has a sense of a step.

  In view of such a current situation, the present invention solves such a problem, it is possible to maintain the strength of the blade plate while making it a concave method, not a perforated method with difficulty in processing and hygiene management, In addition, an object is to provide an epoch-making knife that further improves the separation effect.

  The gist of the present invention will be described with reference to the accompanying drawings.

A plurality of recesses 2 are provided in the blade plate surface 1A in the length direction of the blade plate 1, and a narrow recess 3 narrower than each recess 2 and deeper than each recess 2 is provided between the recess 2 and the recess 2. The narrow recess 3 is an elongated recess whose width in the direction along the blade edge 1B is shorter than that of the recess 2 and whose length in the direction away from the blade edge 1B is longer than that of the recess 2. Is related to the kitchen knife.

  Since the present invention is configured as described above, there is no difficulty in processing and hygiene management because it is not a perforated method, and it is easy to process due to the formation of a recess and is excellent in mass productivity. In addition, since the deep concave portion is between the shallow concave portions, in addition to the shallow concave portion, further sufficient air enters between the cutting piece and the blade plate surface, so that the separation is dramatically improved and only a large number of deep concave portions are provided. In this case, a narrow and deep recess is formed between the shallow recesses, so that the strength of the blade plate is not significantly deteriorated, and the knives can be sufficiently maintained.

In particular, in the present invention , since the length in the direction perpendicular to the blade edge of the narrow recess is longer than each recess, air is more likely to enter, so the separation effect is greatly improved. The above-described effect is satisfactorily exhibited and the knife is more practical.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  Not only are the recesses 2 juxtaposed along the blade edge 1B in the blade plate length direction of the blade plate surface 1A, but also the narrow recesses 3 are provided between the recesses 2, so Not only is the area wide, but the narrow concave portion 3 is deeper than the concave portion 2, so that a gap into which sufficient air enters is formed between the cutting piece and the blade plate surface 1A, and the separation is improved. Since the recess is not formed uniformly, the strength of the blade plate is also maintained.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In this embodiment, a plurality of recesses 2 are provided in the blade plate surface 1A in the length direction of the blade plate 1, and the width between the recesses 2 and 2 is narrower than the recesses 2 and deeper than the recesses. A narrow recess 3 is provided.

  Specifically, the shallow and wide recesses 2 are formed on the blade plate surface 1A at a large number of intervals along the blade edge 1B to improve the separation over a wide range while maintaining the strength of the blade plate. A recess into which air enters is formed, and a deeper narrow recess 3 is formed between the recesses 2.

  Therefore, by providing the narrow recess 3 between the shallow and wide recesses 2, the total area of the recesses is increased, and the narrow recesses 3 between the recesses 2 are deep, so that air sufficiently enters. Furthermore, by providing the narrow recess 3 between the recesses 2, the width of the flat plate surface between the recesses is reduced accordingly, but the narrow recess 3 between the recesses 2 has a different depth. Therefore, air easily enters, and since the narrow concave portion 3 is deep, sufficient air can enter and the adsorbing action can be satisfactorily suppressed, and the separation is greatly improved. In addition, since the narrow recess 3 is narrow and disposed between the recesses 2, the strength of the blade plate itself can be maintained.

  In the present embodiment, the narrow recess 3 is an elongated recess having a width shorter than the recess 2 in the direction along the blade edge 1B and longer than the recess 2 in a direction away from the blade edge 1B. It is said. Thereby, the said effect is exhibited further favorably. In addition, since the length of the narrow concave portion 3 in the direction perpendicular to the blade edge 1B is longer than that of the respective concave portions 2, air is more easily introduced, so that the separation effect is greatly improved.

  Note that the present invention is not limited to the embodiments, and the specific configuration of each component can be designed as appropriate.
