The base 41 is substantially disk-shaped, but has a protruding edge portion 42 projecting upward in a peripheral portion. The inner diameter of the protruding portion 42 is slightly larger than the outer diameter of the main body container 1. Further, a through hole 43 penetrating vertically is formed in the center of the base 41.

Next, the operation of the above configuration will be described. The upper handle 16 can be attached to and detached from the main container 1. To attach the upper handle 16 to the main body container 1, the support shaft 17 of the upper handle 16 is inserted into the bearing groove 12 of the bearing piece 11 of the main body container 1 from its introduction portion 12a, and the upper bearing portion 12b or the lower bearing portion is provided. Lead to 12c. In order to remove the upper handle 16 from the main container 1, the support shaft 17 may be guided from the upper bearing portion 12b or the lower bearing portion 12c to the introduction portion 12a, and may be removed from the introduction portion 12a. Further, the handle 16 attached to the main body container 1 has a position overlapping the lower handle 2 of the main body container 1 as shown in FIG. On the other hand, it can be rotated between the lower handle 2 and a position protruding to the opposite side. At the rotation limit position shown in FIG. 1, the support shaft 17 descends due to gravity and is located in the lower bearing portion 12c of the bearing groove 12, and the leading edge of the connection plate portion 16b of the upper handle 16 on the support shaft 17 side. The rotation of the upper handle 16 is restricted by the contact of the bearing 18 with the side edge of the bearing piece 11.

In addition, a squeezed core 31 is indispensable for making juice. Usually, the squeezed core 31 and the filtration container 26 are used in combination. That is, the squeezed core 31 is used in the filtration container 26. The filter container 26 and the squeezing core 31 can be handled without obstructing the main container 1 particularly by attaching and detaching the handles 28 and 33 to and from the main container 1. The filter container 26 and the squeezed core 31 can be held together by overlapping the handle portions 28 and 33 of the squeezed core 31 with each other. The filtration container 26 is not essential, and only the squeezed core 31 can be used in the main container 1.

Then, with the upper handle 16 removed from the main container 1, or as shown in FIG. 1, with the upper handle 16 attached to the main container 1 turned to the opposite side to the lower handle 2. Then, the squeezed core 31 is stored in the main body container 1, and the vegetables and fruits from which juice is to be squeezed are put in the squeezed core 31. The squeezing core 31 is locked by the flange 32 on the opening edge 4 of the main container 1 or on the upper frame 27 of the filtration container 26 locked on the opening edge 4. It is stored in the main body container 1 with the bottom raised. Then, as shown in FIG. 2, the upper handle 16 attached to the main body container 1 is rotated toward the lower handle 2, and the pressing plate 24 rotatably supported by the lower handle 2 is squeezed. The vegetables and fruits are crushed by the principle of leverage between the bottom of the squeezing core 31 and the pressing plate 24. As a result, the juice is squeezed out of the vegetables and fruits, and the juice falls into the main body container 1 through the through holes 36 on the bottom and side surfaces of the squeezed core 31 and the mesh-shaped filtration container 26. Then, it accumulates in the main body container 1. The use of the filtration container 26 makes it possible to produce juice with less scum of vegetables and fruits than in the case of using only the pressed core 31.

The juice can be squeezed out by holding both the lower handle 2 and the upper handle 16 by hand. Can be mounted on the mounting surface A of the above. In this case, it is only necessary to push down the upper handle 16, so that the work can be performed with less force. When the work is performed with the main body container 1 placed on the mounting surface A, the main body container 1 may be mounted on the rubber base 41 placed on the mounting surface A. Thereby, even if a force in the horizontal direction is applied to the main body container 1 by pressing down the upper handle 16, the main body container 1 is unlikely to slip on the mounting surface A, and the operation of squeezing the juice can be easily performed. The mounting surface A can be prevented from being damaged. Moreover, since the through hole 43 penetrates vertically in the center of the base 41, when the base 41 is attached to and detached from the mounting surface A, or when the main container 1 is attached to and detached from the base 41. When the air between the base 41 and the main body container 1 or between the base 41 and the mounting surface A passes through the through hole 43 to the outside or flows in the opposite direction, the mounting surface is reduced. A, the attachment and detachment of the base 41 to and from the base 41 can be facilitated, and the adhesion between the base 41 and the main container 1 and the adhesion between the base 41 and the mounting surface A can be enhanced. Can be

After the juice is squeezed out in this way, the upper handle 16 is turned to the opposite side to the lower handle 2, or the upper handle 16 is removed from the main body container 1. The child 31 and the filter container 26 are removed. Next, the main container 1 is tilted by holding the lower handle 2, and juice is poured from the spout 5 of the main container 1 into another drinking container such as a cup. At this time, if the upper handle 16 is detached from the main body container 1, the work can be easily performed.

As described above, according to the configuration of the above-described embodiment, the upper handle 16 having the squeezing plate 24 is made detachable with respect to the main body container 1, so that the main body container 1 and the upper handle 16 can be washed. By separating the main body container 1 and the upper handle 16 from each other, the main container 1 can be easily washed without the upper handle 16 including the pressing plate 24 being in the way, and the main body container 1 can be in the way. The upper handle 16 including the pressing plate 24 can be easily washed without any trouble. Also, as described above, by removing the upper handle 16 from the main body container 1, the upper handle 16, particularly the pressing plate 24 thereof, does not hinder the attachment and detachment of the squeezed core 31 and the filtration container 26 to and from the main body container 1. Can be easily performed, and the juice can be easily poured from the main body container 1, thereby improving the usability.

Further, in order to attach and detach the upper handle 16 to and from the main body container 1, a support shaft 17 provided to the upper handle 16 is attached to and detached from a bearing groove 12 formed in a bearing piece 11 provided to the main body container 1. Therefore, as compared with the case where screws or the like are used, the structure in which the upper handle 16 is detachable is simpler, and the operation of attaching and detaching the upper handle 16 can be facilitated. Furthermore, the direction of the bearing groove 12 does not change with the rotation of the upper handle 16 as compared with the case where the support shaft is provided on the main body container 1 side and the bearing groove is provided on the upper handle 16 side. The engagement between the shaft 12 and the support shaft 17 can be more reliably maintained.

As shown in FIG. 2, the squeezing plate 24 of the upper handle 16 attached to the main body container 1 is pressed from below by the bottom surface of the squeezed core 31 accommodated in the main body container 1, vegetables and fruits, and the like. In the supported state, the support shaft 17 side of the compression plate 24 is shorter and lighter than the opposite side of the support plate 22 of the compression plate 24 in the upper handle 16. The other side tries to turn in the downward direction. Also, when the upper handle 16 is pressed down by hand to squeeze juice, the force of the opposite side of the support shaft 17 to rotate in the downward direction becomes stronger. Therefore, the support shaft 17 of the upper handle 16 is located in the upper bearing portion 12b in the bearing groove 12 of the bearing piece 11. Since the upper bearing portion 12b is bent upward from the introduction portion 12a, the state in which the support shaft 17 is engaged with the upper bearing portion 12b is reliably held, and the upper hand portion is used when squeezing juice or the like. The screw 16 does not come off the main container 1 unnecessarily.

On the other hand, as shown in FIG. 1, when the squeezing plate 24 is suspended in the air without being supported, for example, when the upper handle 16 is largely turned to the opposite side to the lower handle 2, the upper c The support shaft 17 of the handle 16 descends in the bearing groove 12 of the bearing piece 11 and is located in the lower bearing portion 12c. Since the lower bearing portion 12c is bent from the introduction portion 12a and extends downward, the state where the support shaft 17 is engaged with the lower bearing portion 12c is securely held, and the support shaft 17 is The upper handle 16 is securely held in the main body container 1 without coming off the groove 12 unnecessarily.

In addition, since the rubber base 41 is provided, when the main body container 1 is placed on the mounting surface A such as a table to squeeze juice, the main body container 1 slips even if a force is applied. It is difficult to prevent the upper handle 16 from coming off the main body container 1 carelessly.

Further, since the bottom portion of the squeezing core 31 and the pressing plate 24 are formed into a corrugated plate shape that matches each other, vegetables and fruits can be reliably crushed to the end, and juice can be efficiently squeezed. . Further, the diameter of the through hole 36 of the squeezing core 31 is set to be as large as about 3 to 4 mm, so that it is difficult for the through hole 36 to be clogged with vegetables and fruit residue. Therefore, the squeezing core 31 can be easily washed.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the introduction portion 12a in the bearing groove 12 is inclined in a direction ascending from the rear end side toward the one side edge of the bearing piece 11, but as shown in FIG. The introduction portion 12a may be inclined in a direction in which the introduction portion 12a descends from the distal end side toward the one side edge of the bearing piece 11, or may be horizontal. However, as shown in FIG. 3, if the introduction portion 12a is inclined in a direction in which the introduction portion 12a rises toward the one side edge of the bearing piece 11 from the rear end portion side, the support shaft 17 of the upper handle 16 is formed in the bearing groove. It is harder to come off from 12.
