【Example】

 First Embodiment Hereinafter, a first embodiment in which the cooking utensil of the present invention is embodied in a kitchen knife will be described with reference to FIGS. 1 to 3.

As shown in FIG. 1, reference numeral 4 denotes a core of the kitchen knife 1, and a mounting hole 2 as a locking portion extending in the longitudinal direction is provided at the tip side of the core 4 so as to be transparent. A base 3 as an accessory member having a substantially H-shaped cross section shown in FIG. 2 is inserted into the mounting hole 2 up to the middle, and the direction of the insertion is changed by 90 ° to engage the tip side of the mounting hole 2. It has been stopped. As shown in FIG. 3, a pair of resin-filled holes 5 as detachment preventing portions are opened from the front end to the base end of the base 3 on both front sides of the base 3. The base 3 has a handle 6 made of synthetic resin formed by insert molding while being locked in the mounting hole 2. At the same time, the pair of resin filling holes 5 are filled with the synthetic resin G so that the mouthpiece 3 and the handle 6 cannot be separated from each other. The handle 6 is provided with a caulking hole 6a. In the core 4, a through hole (not shown) having the same size as the caulking hole 6a is provided at a position corresponding to the caulking hole 6a. The fixing pin 7 is tightly fitted in the caulking hole 6a through the through hole of the core 4.

Now, a method of assembling the kitchen knife 1 will be described. First, the kitchen knife 1 is inserted into the attachment hole 2 up to the middle thereof and rotated by about 90 °. Next, it is moved to the tip of the mounting hole 2 and locked. Next, the handle 6 is formed by insert molding while the base 3 is locked in the mounting hole 2, and the synthetic resin G is caused to flow into the mounting hole 2 and the resin filling hole 5. Then, the fixing pin 7 is tightly fitted into the caulking hole 6a through the through hole of the core 4.

As described above, in the attachment structure of the mouthpiece 3 of the kitchen knife 1 according to the present embodiment, the handle 6 is integrated with the mouthpiece 3 without a gap, so that there is no rattling. Further, when the handle 6 is insert-molded, the synthetic resin G is filled in the resin filling hole 5 and the handle 6 and the mouthpiece 3 are integrally formed, so that the handle 6 does not come off from the mouthpiece 3.

Furthermore, since it suffices to engage the base 3 with the mounting hole 2 and perform insert molding, it is possible to omit the trouble of assembling the handle 6 to the base 3. Second Example Next, a second example will be described with reference to FIG. However, the same components as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted.
