(First embodiment)
1 to 6 show a first embodiment of the present invention. A spoon 1a as a cutlery 1 includes a head portion 2 for picking up food and drink, a grip portion 3 held by a user's fingers, and the head. A bendable arm portion 4 for connecting the portion 2 and the grip portion 3 is provided.

The head portion 2 and the grip portion 3 are each formed by a plastomer such as polypropylene and project bone portions 2a and 3a facing each other.

The arm portion 4 is composed of an arm main body 5 made of thermoplastic elastomer and a core 6 made of a metal wire such as stainless steel embedded in the arm main body 5.

The arm portion 4 is configured such that the bone portions 2a, 3a and the center core 6 are connected to the head body 2 and the bone portions 2a, 3a of the grip portion 3 while the bone portions 2a, 3a and the center core 6 are Embedded in the elastomer and integrated.

Therefore, as shown in FIG. 2, the grip portion 3 of the spoon 1 a is not bendable and has a predetermined shape that is easy to grip, so that it can be suitably held by the user's fingers. On the other hand, the arm part 4 is freely bendable, and as shown in the figure, the arm part 4 has an inclined posture in which the axis 2X of the head part 2 is inclined at a predetermined angle θ from the axis 3X of the grip part 3 as shown in the figure. It can be made to hold | maintain and, thereby, it can make it easy to carry the head part 2 which picked up food and drink to a user's mouth.

When the arm portion 4 is bent, the core 6 made of a metal wire is bent by plastic deformation, and the arm main body 5 made of elastomer is bent following this to maintain a desired bending posture. To do. In the case of the illustrated embodiment, the predetermined angle θ is configured to be arbitrarily selected within a range of 0 degrees and 45 degrees.

As shown in FIGS. 3 and 4, the spoon 1 a is formed by forming the head portion 2 and the grip portion 3 with plastomers such as polypropylene using a predetermined mold, and then the bone portions 2 a and 3 a of the head portion 2 and the grip portion 3. The core 2 is inserted into another mold by inserting both ends of the core 6 into the mold, and the bones 2a, 3a and the core 6 are formed by insert molding in which a thermoplastic elastomer is injected into the mold. It is manufactured by molding the surrounding arm body 5 and then removing it from the mold.

For this reason, the bone portions 2a and 3a are provided with insertion holes 2b and 3b for inserting the end portions of the core 6, respectively. Preferably, the bone portions 2a and 3a are crossed across the insertion holes 2b and 3b.
