The operation knob 41 has a coupling portion 41a inserted between the pair of brackets 23 and 23 at one end thereof, and the coupling portion 41a is inserted between the brackets 23 and 23. As the support shaft 23a is inserted through the pair of brackets 23 and 23 and the coupling portion 41a in the state, the pressing member 4 is coupled to the outer container 2 so as to be rotatable around the support shaft 23a. It is.

The connecting column 42 is fixed by rivets 41b in a state of being inserted between the bent and formed opposing walls of the operating handle 41. The connecting column 42 is installed at a position where the pressing plate 43 can be inserted into the outer container body 21 in a state in which the operating handle 41 is rotated clockwise around the support shaft 23a.

The pressing plate 43 is formed in a disk shape whose diameter is slightly smaller than the inner diameter of the outer container body 21, and the saw blade of the inner container body 31 is disposed on the surface facing the bottom surface of the outer container body 21. A saw blade bottom surface 43a corresponding to the shape bottom surface 35a is provided. The saw blade bottom surface 43a is formed in an isosceles triangle so as to be fitted to the saw blade bottom surface 35a of the inner container body 31, and is parallel to each other from one edge to the other edge. It is formed by the plurality of protruding protrusions (protrusions) 43b and the V-shaped grooves (indentations) 43c formed between the adjacent protrusions 43b.

Therefore, the operation knob 41 shown by the double-dotted line in FIG. 3 is rotated clockwise around the support shaft 23a to insert the pressing plate 43 into the inner container body 31, as shown by the solid line in FIG. Likewise, the projection 43b of the saw blade bottom face 43a of the pressing plate 43 is engaged with the V-shaped groove 35c of the saw blade bottom face 35a of the inner container main body 31, whereby the bottom plate 35 ) And the pressing plate 43 are in a state where the area of the opposing surfaces that can be in close contact with each other is significantly increased as compared with the case where the surface is a flat or smooth curved surface as a whole.

As described above, the hand juicer 1 of the present embodiment forms a saw blade-shaped bottom surface 35a on the bottom plate 35 of the inner container main body 31 into which the adherend F is inserted, while the adherend F is formed. Since the saw blade bottom face 43a opposed to the saw blade bottom face 35a of the bottom plate 35 was provided on the pressing plate 43 for crimping, the adherend F was placed in the inner container main body 31. By rotating the operation knob 41 shown by the double-dotted chain line in FIG. 3 around the support shaft 23a in the inserted state, the pressing plate 43 is inserted into the inner container main body 31 and the solid line in FIG. As shown, the projection 43b of the pressing plate 43 faces the V-shaped groove 35c of the bottom plate 35 via the adherend F, and the V-shaped groove 43c of the pressing plate 43 It will be in the state facing the protrusion 35b of the bottom plate 35. As shown in FIG.

In this state, the operation handle 41 and the fixed handle 22 are gripped by one or both hands to apply a force in the direction in which both the handles 41 and 22 approach each other, so that the adherend F is provided with a protrusion 35b, By pressing between 43b), the crimping liquid is crimped out. The compressed liquid falls vertically downward through the permeation hole 36 and is stored at the bottom of the outer container 2.

Since both of the opposing surfaces of the bottom plate 35 and the pressing plate 43 are saw blade-shaped surfaces 35a and 43a, the bottom plate 35 and the lower surface of the bottom plate 35 and the pressing plate 43 are flat compared with those of the flat or gentle curved surface. The opposing area of the pressing plate 43 becomes remarkably large, and thus, the crimping efficiency is increased by the increment of the opposing area, whereby the crimping liquid can be compressed more efficiently than the conventional one.
