By gripping the grip portion, the food can be pushed through with a blade, or the skin of the food can be peeled with a blade. As a kitchen knife with enhanced safety, there is one disclosed in Non-Patent Document 1. The kitchen knife disclosed in the same document is a design relating to functional beauty with enhanced safety.

Design Registration No. 603270

According to the kitchen knife disclosed in Patent Document 1, there is room for improvement in safety. That is, in the kitchen knife disclosed in Patent Document 1, the safety of the finger of the dominant arm can be improved to a certain extent by inserting the finger into the hole. However, various cutting methods are known, and the usage of kitchen knives is different for each person, and there is room for improvement in safety of the kitchen knives disclosed in Patent Document 1. In particular, the kitchen knife disclosed in Patent Document 1 cannot improve the safety of the non-dominant finger when pushing the food material with a blade.

Therefore, the present invention has been made in view of such a problem, and an object of the present invention is to provide a kitchen knife capable of enhancing finger safety.

In order to solve the above problem, according to the first aspect of the present invention, a blade portion provided with a blade and a ridge and a grip portion for gripping the food when the blade of the blade portion pushes through the food material are provided. In the kitchen knife, the blade portion is provided with one or more blunt protrusions for protecting fingers when pushing the food material with the blade, and the blunt protrusion is not provided with a blade, and the blade is not provided. A kitchen knife is provided, which is characterized by protruding in the opposite direction to the peak.

According to this configuration, the blunt protrusion creates a gap between the blade and the cutting board, so that even if a finger is accidentally inserted between the blade and the cutting board, the safety of the finger can be improved. can. The protruding height of the blunt protruding portion may be arbitrary, but considering the function of protecting the fingers, it is preferably about 1.5 cm or more. However, it may be 1.5 cm or less in consideration of the height for avoiding amputation of a child's small finger or a severe adult's finger and the usability of a kitchen knife. The present invention is characterized in that a component element that goes against the ease of cutting, which is the original function of a kitchen knife, is provided. However, for example, when pushing through foods with hard parts such as fish ara and pumpkin and slippery foods such as satoimo and long potatoes, the gap is a finger for users who are worried about injuries due to slippery blades. It is possible to protect and safely cut off the ingredients halfway, and then shift the uncut ingredients forward and cut them, providing a suitable pumpkin that contributes to the reduction of injuries caused by pumpkins and contributes to society. can. Also, for example, if you have a kitchen knife that can protect your fingers in addition to a normal kitchen knife, the user can select this kitchen knife and use it safely and with peace of mind when pushing out foodstuffs with slippery blades. Can be done. Although such a blunt protrusion may be fixed separately from the blade, the manufacturing process of the blunt protrusion can be simplified by integrally molding the blunt protrusion. Further, when the blunt protrusion portion that is separate from the blade portion is fixedly formed, the blade portion can be formed in advance as in the conventional case, and the blade manufacturing process can be simplified. Further, the material and strength of the blunt protrusion may be any material as long as it can be used against the impact of the cutting board at the time of pushing and cutting, such as the same material as the blade and a synthetic resin material. The method of fixing the blunt protrusion may be a well-known method as long as it can be fixed without impairing the purpose.

The present invention has various applications. The following application examples can be implemented in appropriate combinations. For example, one blunt protrusion may be provided. According to such a configuration, there are many parts that can be used as ordinary kitchen knives without blunt protrusions. In particular, the blunt protrusion may be provided closer to the grip than the center in the length direction of the blade. Many parts of the tip part from the center in the length direction of the blade can be used as an ordinary kitchen knife.

Further, two blunt protrusions may be provided. According to such a configuration, peeling can be performed with a blade between two blunt protrusions. For example, by providing one blunt protrusion at an end near the grip portion, a thumb is attached to the blunt protrusion. When peeling with the base of the finger attached, it becomes easier to prevent the thumb from hitting the sliding blade, and the safety of the finger can be improved. In this case as well, the two blunt protrusions may be provided closer to the grip portion than the center in the length direction of the blade. The same applies when there are three or more blunt protrusions. However, it may be arranged freely depending on the application. For example, by providing the blunt protrusion at the tip, when the kitchen knife is swung around, the protrusion hits first and the safety can be improved. This kitchen knife provided with a blunt protrusion at the tip can be provided as a safety kitchen knife for children's practice or at homes where there are children who want to touch the kitchen knife.

The number of blunt protrusions (1, 2, or 3 or more) is the number in the length direction of the blade (1, 2, or 3 or more), and the thickness direction and width of the blade are defined. , The form of the blunt protrusion may be arbitrary. By increasing the thickness of the blunt protrusion or by fixing a plurality of blunt protrusions in the thickness direction of the blade, the strength of the blunt protrusion can be increased and when the blunt protrusion itself hits a finger. It is safe because the degree of finger injury can be reduced by the thickness.

Further, at least one of the blunt protrusions may be provided with a through hole penetrating in a direction orthogonal to the protrusion direction of the blunt protrusion. According to such a configuration, it is possible to easily confirm the condition of the food material on the opposite side by looking through the through hole at the time of pushing off. Further, by providing a blunt protruding portion having a through hole having a size large enough to allow a finger to enter at the end on the gripping portion side, the finger to be gripped can be inserted and operated, and the finger can be safely operated.

Further, at least one of the blunt protrusions may be provided with a roller rotatably in the length direction of the blade. According to such a configuration, since the blade can be smoothly moved in the front-rear direction by the roller, it can be easily cut by pushing and pulling by using the roller. Therefore, the food can be cut with a light force. In addition, chopped green onions and uncut decorations such as cucumber can be easily performed without the need for skilled techniques.

Further, the peak may be provided with a display unit for displaying the position where the blunt protrusion is provided. According to such a configuration, the position of the blunt protrusion can be confirmed without looking into the blunt protrusion from the lateral direction, which is convenient.

According to the second aspect of the present invention, the cooking utensil is characterized in that the blunt protrusion is composed of a kitchen knife provided with two blunt protrusions and a cutting board having a width slightly smaller than the distance between the two blunt protrusions. Provided. According to such a configuration, if a cutting board is arranged between the two blunt protrusions, the food material can be easily pushed out by eliminating the gap at the time of pushing off. For example, it is preferable that one of the blunt protrusions is provided in the direction of the tip portion from the center in the length direction of the blade, and the distance between the two blunt protrusions is large. Further, for example, by providing a blunt protruding portion at the tip, when the kitchen knife is swung around, the protruding portion hits first and the safety can be improved. The set can be provided as a safety kitchen knife set for children's practice or at homes with children who want to touch the kitchen knife.

Further, the cutting board may have at least a storage portion for accommodating the blade portion. According to such a configuration, the blade portion is stored in the cutting board, so that it is safe. In addition, since the cutting board and kitchen knife can be integrated, it is convenient to carry and store.
In addition, you can rest assured that you will not have to search for a dedicated cutting board.
