In the present embodiment, the engagement pieces 27 and 37 that may have the engagement groove 25 and the engagement protrusion 38 correspond to the “rotation locking portion” according to the present invention.

  The description regarding the structure of the pallet 10 with a container group of this embodiment is above. Next, the effect is demonstrated taking the case where the pallet 10 with a container group is used for cultivation of a plant as an example.

  The container 30 removed from the pallet 11 is used as a pot, and seedlings are potted in a plurality of containers 30. And the container 30 is attached in order from the container fitting part 18 of the edge part of the pallet 11. As shown in FIG. The pot planting may be performed after the container 30 is attached to the pallet 11.

  In order to attach the container 30 to the pallet 11, the lower surface opening of the lower surface recess 39 of the container 30 is opposed to the pallet side retaining engagement portion 27 of the container fitting portion 18. At this time, the side opening 31 </ b> A and the pallet-side retaining engagement portion 27 may be combined when the container 30 is viewed from the side. Further, the four first vertical ribs 34A on the outer periphery of the container 30 are arranged on the pallet-side retaining engagement portion 27 with reference to the rotational position slightly shifted in the clockwise direction from the position facing both the vertical and horizontal directions of the pallet 11. The lower surface opening of the lower surface recess 39 may be opposed.

  Next, the container 30 is pushed into the container fitting portion 18 until the side opening 31 </ b> A of the container 30 is hidden in the container fitting portion 18. Then, the pallet side retaining engagement portion 27 enters the lower surface recess 39, and the side wall 31 of the container 30 and the lower surface of the cylindrical rib 35 are in contact with the bottom wall 21. If the container 30 cannot be pushed in, the pallet-side retaining engagement portion 27 can face the lower surface opening of the lower surface recess 39 and push the container 30 if the container 30 is appropriately rotated to one side and the other side. it can.

  When the container 30 is pushed into the container fitting portion 18, it is rotated counterclockwise. Then, the engaging piece 37 of the container-side retaining engagement portion 40 enters under the engaging piece 24 of the pallet-side retaining engagement portion 27, and the engaging piece 24 enters the inclined surface 38B (see FIG. 7) of the engaging protrusion 38. The guide surface 24G (see FIG. 5) contacts. When the container 30 is further rotated counterclockwise, the guide surface 24G and the inclined surface 38B are in sliding contact with each other, the engagement piece 24 rides on the engagement protrusion 38, and the engagement pieces 24 and 37 are elastically moved away from each other. Deform. Further, when the container 30 is rotated in the counterclockwise direction, the engagement pieces 24 and 37 are elastically restored, and the engagement groove 25 and the engagement protrusion 38 are engaged with each other in an uneven manner. Thus, the attachment of the container 30 to the container fitting portion 18 is completed. As shown in FIG. 1, the plurality of containers 30 are attached to the plurality of container fitting portions 18 of the pallet 11 to form the container group-attached pallet 10.

The rotation is prevented by the engagement. Further, as shown in FIG. 1, the four first vertical ribs 34A of each container 30 face the vertical direction and the horizontal direction of the pallet 11, and as shown in FIG. 8, between the adjacent containers 30 and 30. Thus, the vertical surfaces 34C and 34C of the first vertical ribs 34A and 34A are in contact with or adjacent to each other.

  The container group-attached pallet 10 may be moved to a plant planted in the container 30 according to the growing condition. In such a case, the fork of the forklift can be inserted into the fork insertion holes 12 and 12 to lift and convey the container group-attached pallet 10. At that time, even if the forklift passes through the step and receives an impact, each container 30 is prevented from coming off by the container fitting portion 18, so that the container 30 does not come off and fall. Further, the containers 30, 30 that are prevented from coming off by the container fitting portion 18 and adjacent to each other or abut each other, disperse the load received by the container 30 from the lateral direction, and the fitting portion of the pallet 11 and the container 30 and Deformation and breakage of the engaging portion can be suppressed.

  If a forklift capable of rotating the fork laterally is used, when the harvesting of the plant in the container 30 is completed and the unnecessary matter is discharged from the container 30, the pallet 11 is inverted together with the plurality of containers 30 to form the plurality of containers 30. The contents inside can be discharged at once.

  In addition, when the container group pallet 10 with the containers 30 emptied is stacked, the flanges 33 of the containers 30 and 30 of the lower container group pallet 10 are arranged on the lower surface 13U of the upper end side container group pallet 10. The pallet 10 with a container group is stabilized in contact with the pallet 28, and the stacked state of the pallet 10 with the container group is stabilized. Further, a drain hole 32A is drilled in the bottom wall 32 of the container 30, and the through hole 26 corresponding to the drain hole 32A is also formed in the pallet 11, so that the pallet 10 with the container group is reused during plant growth. Therefore, water can be smoothly drained from the container 30 when it is washed for.

  As described above, in the container group-equipped pallet 10 of the present embodiment, the container 30 fitted to the container fitting portion 18 is prevented from being detached by the engagement between the pallet side retaining engagement portion 27 and the container side retaining engagement portion 40. Therefore, even if the pallet 11 is tilted or receives an impact, the container 30 is not detached from the container fitting portion 18, and a plurality of containers 30 can be stably conveyed. Further, the pallet 11 can be reversed together with the plurality of containers 30 by a forklift, and the contents in the plurality of containers 30 can be discharged at once. Further, the vertical surfaces 34C and 34C of the adjacent containers 30 and 30 that are prevented from being detached by the container fitting portion 18 are adjacent to or contact each other, so that the load that the container 30 receives from the lateral direction is dispersed, and the pallet 11 and Deformation and breakage of the fitting portion of the container 30 can be suppressed.

  Further, in the pallet 10 with a container group of the present embodiment, the operation necessary for preventing the container 30 from falling into the container fitting portion 18 is a rotation operation, and the direction of the rotation operation and the container 30 are prevented from falling off. Since the direction to perform is orthogonal, a large retaining force can be obtained with a small operating force. Furthermore, the container 30 is prevented from rotating at the second position by the engagement between the engagement groove 25 and the engagement protrusion 38, so that the engagement for preventing the container 30 is stabilized. In addition, depending on whether or not the vertical surfaces 34C, 34C of adjacent containers 30 are adjacent or in contact with each other, whether or not the containers 30 are both disposed at the second position, that is, the containers 30 are prevented from rotating. It can be easily confirmed whether or not it is in a state of being prevented from being detached.
