FIG. 2 is a diagram showing each of the spoon main body 2, the grip portion 4, and the auxiliary tool 5 individually.

  As shown in FIG.1 and FIG.2, the spoon main body 2 has the bowl part 21 in which the hollow 23 was formed, and the handle | grip part 22 extended | stretched in the direction away from the hollow 23 by using the part 21 as a base end. The edge 24 of the recess 23 in the bowl portion 21 has an elliptical shape with dimensions of a major axis length a1 (for example, a1 = 3 cm) and a minor axis length b1 (for example, b1 = 1.5 cm). The base end of the handle portion 22 is at one of the edges 24 facing the long axis a1.

  The handle 22 has a cylindrical shape having dimensions of a diameter R1 (for example, R1 = 5 mm) and a length L1 (for example, L1 = 7 cm). The extending direction of the handle portion 22 is inclined upward with respect to the major axis a1 direction of the bowl portion 21. A collar 26 is provided at a position slightly away from the base end of the handle 22. A screw thread 27 that spirals around the peripheral wall of the handle 22 is provided at the tip 25 of the handle 22.

  The grip portion 4 has a cylindrical shape with dimensions of a diameter R2 (for example, R2 = 8 mm) and a length L2 (for example, L2 = 6.5 cm). The grip part 4 has a hole 41 that penetrates between both end faces of the part 4. The diameter R <b> 2 ′ of the hole 41 is slightly larger than the diameter R <b> 1 of the handle portion 22.

  The auxiliary tool 5 has a weight 51 and a rod body 52. FIG. 3 is a view of the auxiliary tool 5 of FIG. The weight 51 of the auxiliary tool 5 is made of a material such as metal in a spherical shape. The weight 51 is heavier than the bowl portion 21. The weight 51 is fixed to one end of the rod body 52. The rod body 52 is formed by bending a circular cylinder having a diameter R3 (for example, R3 = 6 mm) into a bow shape. A cap 53 is formed at the end of the rod 52 opposite to the side on which the weight 51 is fixed. The cap part 53 has a cylindrical shape. A flange 54 is provided at a position slightly away from the opening 55 at the tip of the outer peripheral surface of the cap portion 53 toward the bottom portion 56. The diameter R3 ′ of the inner peripheral surface 57 of the cap portion 53 is larger than the diameter R1 of the handle portion 22.

  In this embodiment, the spoon main body 2, the holding part 4, and the auxiliary tool 5 are integrated in the following procedures. First, the handle portion 22 of the spoon body 2 is inserted into the hole 41 of the grip portion 4 from the tip portion 25 side (FIG. 4A). Next, the recess direction of the bowl portion 21 of the spoon body 2 (the direction from the center of the edge 24 of the bowl portion 21 toward the center of the bottom of the recess 23) and the extending direction of the rod body 52 of the auxiliary tool 5 (the weight in the rod body 52). The end portion 25 of the handle portion 22 and the cap portion 53 of the rod body 52 are abutted with each other facing downward (in the direction in which the end portion on the side to which 51 is fixed is directed) (FIG. 4B). And the cap part 53 is mounted | worn with the front-end | tip part 25 of the pattern part 22 by making the front-end | tip part 25 of the handle | pattern part 22 and the cap part 53 of the auxiliary tool 5 approach as it is, and inserting the front-end | tip part 25 in the cap part 53 ( FIG. 4 (C)).

  Here, in FIG. 1, the grip portion 4 of the spoon 10 is sandwiched from both sides by the collar 26 of the handle 22 and the collar 54 of the rod 52. The grip portion 4 of the spoon 10 covers the handle portion 22 so that the handle portion 22 can rotate in the hole 41 of the grip portion 4. Further, the spoon body 2 and the auxiliary tool 5 in the spoon 10 are integrated in a state in which the recess direction of the bowl portion 21 and the extending direction of the rod body 52 are both directed downward. For this reason, the weight 51 of the auxiliary tool 5 faces the vertical direction and is connected via the weight 51, the rod body 52, and the handle portion 22 regardless of the relationship between the orientation of the grip portion 4 of the spoon 10 and the vertical direction. The bowl portion 21 is kept in the direction (upward) opposite to the vertical direction.

The above is the details of the configuration of the present embodiment. According to this embodiment, the following effects can be obtained.
First, in the infant spoon 10 according to the present embodiment, the handle portion 22 of the handle portion 22 and the rod body 52 that are members interposed between the bowl portion 21 and the weight 51 extends linearly. The body 52 extends in a direction different from that of the handle 22. And the handle | grip part 22 and the holding part 4 which is a member which covers this can rotate relatively. Therefore, as shown in FIG. 5, the arm 4 is moved toward the mouth while keeping the wrist angle at the time when the infant scoops food with the bowl portion 21 of the spoon 10, and the grip portion 4 held by the infant's fist. Even when the handle is tilted toward the mouth, the handle 22 in the gripper 4 rotates in the direction opposite to the tilting direction of the gripper 4 (the direction of arrow B in FIG. 5) (the direction of arrow B ′ in FIG. 5). Thus, the bowl portion 21 is kept upward. Therefore, the infant can put the food on the bowl portion 21 of the spoon 10 into the mouth without spilling.

  Second, the infant spoon 10 according to the present embodiment includes the spoon body 2 (the bowl portion 21 and the handle portion 22), the auxiliary tool 5 (the rod body 52 and the weight 51), and the grip portion 4. Then, the infant spoon 10 is formed by integrating the spoon body 2 and the auxiliary tool 5 with the depression direction of the bowl portion 21 of the spoon body 2 and the extending direction of the rod body 52 of the auxiliary tool 5 facing downward. It is comprised so that the hollow direction of the part 21 and the extending | stretching direction of the rod 52 may become the same. Therefore, in the infant spoon 10, the bottom of the recess 23 of the bowl portion 21 always faces the vertical direction, and the edge 24 of the recess 23 of the bowl portion 21 always faces the opposite side (upward direction) of the vertical direction. Therefore, it is possible to make the food more difficult to spill than when the recess direction of the bowl portion 21 and the extending direction of the rod body 52 are not the same.

  3rdly, in the infant spoon 10 of this embodiment, the cap part 53 is formed in the edge part on the opposite side to the side to which the weight 51 is fixed in the rod 52 of the auxiliary tool 5. As shown in FIG. Therefore, the front end portion 25 of the spoon body 2 is inserted into the cap portion 53 to connect the spoon main body 2 and the auxiliary tool 5, and the front end portion 25 of the spoon main body 2 is removed from the cap portion 53, and the spoon main body 2 and the auxiliary tool 5 are connected. It is possible to easily perform the attaching / detaching operation such as separation. Therefore, it is possible to easily clean the outer peripheral surface of the handle portion 22 and the inner peripheral surface of the hole 41 of the grip portion 4 which are indispensable operations for keeping the infant spoon 10 clean.

  Fourth, the handle portion 22 and the rod body 52 of the infant spoon 10 of the present embodiment have hooks 26 and 54 that sandwich the grip portion 4 from both sides when the cap portion 53 is attached to the distal end portion 25 of the handle portion 22. Is provided. The distance between the collars 26 and 54 when the cap portion 53 is attached to the distal end portion 25 of the handle portion 22 (FIG. 1) is the same as the length L2 of the handle portion 22. For this reason, in a state where the cap portion 53 is attached to the distal end portion 25 of the handle portion 22, the movement of the handle portion 22 in the direction parallel to the rotation axis is restricted by the flanges 26 and 54. Accordingly, it is possible to prevent a situation in which the handle portion 22 of the infant spoon 10 moves to the bowl portion 21 side or the rod body 52 side and becomes difficult to handle.

Second Embodiment
FIG. 6 is a view showing an infant spoon 10A according to a second embodiment of the present invention. FIG. 7A is a diagram showing a state where the spoon main body 190 and the grip portion 104 in the infant spoon 10A are separated. As shown in FIGS. 6 and 7A, in the spoon 10A, the bowl portion 121, the handle portion 122, the rod body 152, and the weight 151 are inseparably formed as a spoon body 190. In the spoon 10 </ b> A, the grip portion 104 is provided with a slit SL that extends in the length direction of the hole 141 along the hole 141 in the portion 104.

  In FIG. 7A, a weight 151 has a shape in which a lower part of a substantially spherical body is cut out with a plane perpendicular to the radial line of the spherical body being cut. The flat surface below the weight 151 forms a bottom surface BT. A portion of the weight 151 opposite to the bottom surface BT is connected to the lower end of the rod body 152. The rod body 152 extends toward the side opposite to the side having the bottom surface BT. The tip of the rod body 152 is connected to the handle 122. The rod body 152 and the handle 122 intersect at an acute angle. The bowl 121 is connected to the end of the handle 122 opposite to the rod 152 side.

  The edge 124 of the recess 123 in the bowl 121 has an elliptical shape with dimensions of a major axis length a11 (a1 = 3.4 cm) and a minor axis length b11 (b11 = 2 cm). The extending direction of the rod body 152 is the same as the recess direction of the bowl portion 121 (the direction from the center of the edge 124 of the bowl portion 121 toward the center of the bottom of the recess 123). The extending direction of the handle 122 at the base end of the bowl 121 is inclined to the opposite side of the recess by θ1 (θ1 = 15 degrees) with respect to the edge 124 of the recess 123 of the bowl 121. The handle portion 122 is provided with two flange portions 126 and 154. The two flanges 126 and 154 are separated by the same distance as the length of the grip 104.

  The edge 124 of the bowl portion 121 is parallel to the bottom surface BT of the weight 151. As shown in FIG. 7A, when the spoon body 190 is placed with the bottom of the bowl portion 121 and the bottom portion BT of the weight 151 facing down, the edge 124 of the recess 123 of the bowl portion 121 is horizontal (the spoon body 190 is Parallel to the placed surface).

  FIG. 7B is a view of the grip portion 104 of FIG. FIG. 7C is a view of FIG. 7B viewed from the direction of arrow C. As shown in FIGS. 7B and 7C, the width of the slit SL of the grip portion 104 is smaller than the diameters of the hole 141 and the handle portion 122. For this reason, this spoon 10A applies the slit SL of the grip portion 104 to the handle portion 122 and pushes it toward the handle portion 122, so that the handle portion 122 expands the slit SL of the grip portion 104 and fits into the hole 141. It is like that. In a state where the handle portion 122 is fitted in the hole 141 of the grip portion 104, the handle portion 122 can rotate in the hole 141 of the grip portion 104.

The above is the details of the configuration of the present embodiment. According to this embodiment, the following effects can be obtained.
First, in the present embodiment, the bowl portion 121, the handle portion 122, the rod body 152, and the weight 151 are integrally formed as the spoon body 190, and the grip portion 104 extends along the hole 141 in the portion 104. A slit SL extending in the length direction of the hole 141 is provided. Then, the slit 122 of the grip portion 104 is pressed against the handle portion 122 and pressed toward the handle portion 122 so that the handle portion 122 expands the slit SL of the grip portion 104 and fits into the hole 141. ing. Therefore, according to the present embodiment, it is possible to more easily attach the grip portion 104 to the spoon body 190. Moreover, in this embodiment, since the weight 151 cannot be separated from the spoon main body 190, it is possible to prevent an accident such that an infant swallows the weight 151. Further, in the present embodiment, the number of parts is less than that in the first embodiment, which is advantageous in terms of cost.

  Secondly, in the present embodiment, the weight 151 has a shape in which a substantially lower part of the sphere is cut out with a plane perpendicular to the radial line of the sphere as a cut surface. The bottom surface BT is formed, and when the spoon body 190 is placed with the bottom of the bowl portion 121 and the bottom portion BT of the weight 151 facing down, the edge 124 of the recess 123 of the bowl portion 121 is horizontal (the spoon body 190 is placed Parallel to the surface). For this reason, even an infant can easily perform operations such as placing the grasping spoon 10A on the table and grasping and lifting the spoon 10A on the table. Even if liquid such as soup is put in the bowl 121 and placed on the table, the liquid in the bowl 121 does not spill out of the bowl 121. Therefore, even an infant can eat using the spoon 10A without soiling the table with food.

  Thirdly, in the present embodiment, the recess 123 of the bowl portion 121 has an elliptical edge 124 having a dimension in which the length of the major axis a11 is 3.4 cm and the length of the minor axis b11 is 2 cm. The extending direction of the handle portion 122 is inclined to the opposite side to the recess direction of the bowl portion 121 by θ1 (θ1 = 15 degrees) with respect to the surface including the edge 124 of the recess 123 of the bowl portion 121. Here, as shown in FIG. 7A, when the inclination angle θ1 of the handle 122 increases, the handle 122 of the spoon main body 190 is fitted into the hole 141 of the grip 104 and the two are integrated. A distance D between the rotation axis AX of the handle portion 122 and the tip portion of the bowl portion 121 is increased, and the rotation of the bowl portion 121 is easily urged. On the other hand, when the inclination angle θ1 of the handle portion 122 is reduced, the rotation axis AX of the handle portion 122 and the bowl portion 121 in a state in which the handle portion 122 of the spoon body 190 is fitted into the hole 141 of the grip portion 104 and both are integrated. The distance D between the tip of the bowl portion 121 and the bowl portion 121 becomes difficult to gain momentum. The inventor of the present application made prototypes with various changes in the inclination angle θ1 of the handle 122 and confirmed that the infant eats food by bringing it to the infant. It is the inclination angle θ1 that the infant can handle the spoon 10A most comfortably. It was confirmed that θ1 = 15 degrees.
