  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiment.

<Embodiment>
FIG. 1 is an external perspective view showing the mounting tray 1 according to this embodiment, and FIG. 2 is a development view of the mounting tray 1. The mounting tray 1 is a tray on which an object to be packaged 100 such as an image forming apparatus or a household appliance is mounted, and is formed so as to fit completely in a rectangular parallelepiped packaging box (not shown). .

  The loading tray 1 is formed by bending a corrugated cardboard. The mounting tray 1 includes a bottom surface portion 2 having a mounting region R on which an article to be packaged 100 is mounted, a pair of side surface portions 3 and 4 that are adjacent to the bottom surface portion 2 and face each other, and a pair of side surface portions. A first stopper portion 5 and a pair of second stopper portions 6 for restricting the movement of the article to be packaged 100 in the direction along 3 and 4 are provided. In the following description, the vertical direction of the bottom surface portion 2 means the direction along the pair of side surface portions 3 and 4, and the horizontal direction of the bottom surface portion 2 means the facing direction of the pair of side surface portions 3 and 4. It shall be.

  The side surface portions 3 and 4 are formed by vertically folding the outer portion of the bottom surface portion 2 at the folds 7 and 8 of the loading tray 1 shown in FIG. The side surface parts 3 and 4 are opposed to each other in the lateral direction of the loading tray 1, thereby covering the side surface of the article 100 to be packaged.

  Each of the side surfaces 3 and 4 is provided with a handle 30 that can be grasped by a hand when an operator puts the loading tray 1 in and out of the packaging box. The handle portion 30 has a handle hole 31 extending in the vertical direction. The handle hole 31 penetrates the side surfaces 3 and 4 in the thickness direction, and has a size and shape that allows an operator to insert a hand and hang it.

  When an operator puts the package object 100 in and out of the packaging box (not shown), the worker starts from the front side of the packaging box (the labor side in FIG. 1) and the handle hole of the handle portion 30 of the loading tray 1. A hand is placed on 31 to raise and lower the loading tray 1. Thereby, the packaging operation can be easily performed as compared with the case where the article 100 is directly raised and lowered.

  The first stopper portion 5 and the pair of second stopper portions 6 are three-dimensionalized by bending a part of the cardboard and project upward from the end portion of the bottom surface portion 2. The first stopper portion 5 and the pair of second stopper portions 6 are configured such that when the bottom surface portion 2 is tilted when an operator puts the loading tray 1 in and out of the packaging box, the article to be packaged 100 is on the bottom surface portion 2. The vertical movement of the article to be packaged 100 is restricted so that it does not fall off.

  The first stopper portion 5 is formed across the entire lateral direction at one longitudinal end of the bottom surface portion 2. The first stopper portion 5 folds the cardboard at the creases 9 to 12 shown in FIG. 2 and inserts the pair of insertion pieces 13 into the pair of insertion holes 14 respectively, and then a pair of folded pieces 26 formed on the bottom surface portion 2. Are respectively bent and engaged with a pair of notch holes 15.

  The pair of second stopper portions 6 is formed at the other end portion in the vertical direction of the bottom surface portion 2. The pair of second stopper portions 6 are disposed symmetrically with a space therebetween with the horizontal center position of the bottom surface portion 2 interposed therebetween. Each of the second stopper portions 6 is smaller than the first stopper portion 5 in order to make the mounting tray 1 compact. Specifically, the lateral width of each second stopper portion 6 is approximately 1/5 of the lateral width of the first stopper portion 5, and the height of each second stopper portion 6 is the first stopper. It is approximately 1/3 of the height of the portion 5 (height of the intermediate portion excluding both end portions).

  Each second stopper portion 6 is formed using a strip-shaped portion 61 and a reinforcing piece 67 formed on the cardboard in the unfolded state.

  The strip-shaped portion 61 has a strip shape extending in the horizontal direction. The strip-shaped portion 61 is formed adjacent to the placement region R of the article 100 to be packaged on the bottom surface portion 2 and on the outside thereof. The strip-shaped portion 61 is formed by making a cut extending in the lateral direction in a part of the bottom surface portion 2.

  In the strip-shaped portion 61, five folds 17 to 21 are formed in this order from the base end edge side to the front end edge side. The fold line 17 is formed at the same position as the base end edge of the strip-shaped part 61. The folds 18 to 21 are formed at an intermediate portion between the base end edge and the front end edge of the strip-shaped portion 61.

  A rectangular insertion hole 64 extending in the lateral direction is formed between the crease 18 and the crease 19 in the strip-shaped portion 61. An insertion piece 68 formed at the tip of a reinforcing piece 67 described later is inserted into the insertion hole 64.

  A rectangular insertion hole 63 is formed in the strip portion 61 between the crease 18 and the insertion hole 64 and adjacent to the crease 18. An insertion piece 62 that can be inserted into the insertion hole 64 is connected to the tip of the strip-shaped portion 61. The width of the insertion piece 62 is smaller than the width of the strip portion 61.

  Between the fold line 20 and the fold line 21 in the strip-shaped part 61, a rectangular notch part 66 opened to the outside in the vertical direction is formed. A trapezoidal folded piece 16 is formed between the pair of strip-shaped portions 61 in the bottom surface portion 2 (between the left and right folds 17 in FIG. 2) to be engaged with the notch portion 66 by bending.

  The reinforcing piece 67 is formed at the other end in the vertical direction of the bottom surface 2 (upper end in FIG. 2). The reinforcing piece 67 has a rectangular shape extending vertically in the overall view. The reinforcing piece 67 is configured to be bent by cutting a part of the bottom surface portion 2 into a U shape. The reinforcing piece 67 is formed with three fold lines 22 to 24 arranged at intervals in the vertical direction. The fold line 22 is formed at the same position as the base end edge of the reinforcing piece 67. The folds 23 and 24 are formed between the base end edge and the front end edge of the reinforcing piece 67. An insertion piece 68 narrower than the reinforcing piece 67 is connected to the tip of the reinforcing piece 67.

  Next, with reference to FIGS. 3-7, the formation procedure of each 2nd stopper part 6 (only one 2nd stopper part 6 is shown in FIGS. 3-6) is demonstrated. First, as shown in FIG. 3, the strip-shaped portion 61 is bent at folds 19 to 21 to form a square frame, and then the insertion piece 62 is inserted into the insertion hole 63. Then, this square frame is rotated in the counterclockwise direction of FIG. 3 by the folds 18 and 17 to form the frame-shaped portion 60 (see FIG. 4). In this state, the insertion hole 64 is located on the upper side wall of the frame-like part 60, the notch part 66 (see FIGS. 6 and 7) is located on the lower side wall of the frame-like part 60, and the reinforcing piece 67 is the frame-like part. It is located adjacent to 60 on the placement region R side.

  After the frame-shaped portion 60 is formed, the reinforcing piece 67 is folded inside the frame-shaped portion 60 at the folds 22 and 23 (that is, the base end portion of the reinforcing piece 67) as shown in FIG. The portion is folded back to the mounting region R side at an acute angle by the fold line 24 (see FIG. 7), and the insertion piece 68 at the tip is inserted into the insertion hole 64. Next, as shown in FIG. 6, the folded piece 16 formed at the end of the bottom surface 2 opposite to the placement region R side is bent and engaged with the notch 66. Thus, the assembly of the second stopper portion 6 is completed. In addition, the assembly order of the 2nd stopper part 6 is not limited to the order described here.

  According to the mounting tray 1 configured as described above, when the mounting tray 1 tilts when an operator puts the mounting tray 1 in and out of the packaging box, the first stopper portion 5 or the pair of second stoppers. It is possible to receive the article 100 to be packaged by the portion 6 and prevent the article 100 from falling from the loading tray 1.

  Here, the pair of second stopper portions 6 is smaller than the first stopper portion 5 in order to make the mounting tray 1 compact. For this reason, when the operator places the article to be packaged 100 on the mounting tray 1, the object to be packaged 100 may be mistakenly placed on the second stopper portion 6. As a result, there is a possibility that the second stopper portion 6 is crushed by the article 100 and damaged.

  On the other hand, in the present embodiment, the reinforcing piece 67 is folded back inside the frame-shaped portion 60 with the base end portion as a fulcrum and extends substantially parallel to the lower side wall of the frame-shaped portion 60, and then at an acute angle. It is configured to support the upper side wall of the frame-like portion 60 from below by being folded back and inserting the insertion piece 68 at the tip thereof into the insertion hole insertion hole 64 (see FIG. 7). Thereby, the vertical rigidity of the second stopper portion 6 can be remarkably improved by the reinforcing piece 67. Therefore, it is possible to avoid as much as possible that the second stopper portion 6 is crushed and damaged by the packaged object 100 when the worker places the packaged object 100 on the mounting tray 1.

  Further, since the reinforcing piece 67 receives a part of the load from the packaged object 100 when the mounting tray 1 is tilted, the rigidity in the moving direction (vertical direction) of the packaged object 100 of each second stopper portion 6. Can be improved.

  Further, in the present embodiment, a folded piece 16 that can be folded back to the frame-like part 60 side is formed on the part of the bottom face 2 opposite to the placement region R side of the frame-like part 60. A notch 66 that opens to the opposite side to the placement region R side is formed on the lower side wall of the, and the folded piece 16 is engaged with the notch 66 (see FIGS. 6 and 7). . Therefore, the load from the article 100 acting on each second stopper portion 6 can be received also by the folded piece 16. Therefore, the rigidity of each second stopper portion 6 in the moving direction of the article to be packaged 100 can be further increased.

  As described above, the present invention is useful for a placement tray for an object to be packaged.
