Description

  The present invention relates to a storage tray in which a storage recess for storing a storage object is formed.

  When storing and transporting electronic components and the like, a storage tray in which a plurality of storage recesses are formed so as to be able to store objects to be stored such as electronic components is used. Such storage trays are generally formed by vacuum forming a synthetic resin such as polypropylene, polystyrene, or PET.

  For example, according to the storage tray shown in Patent Document 1, the storage trays that are stacked up and down during storage are rotated 180 degrees so that the storage objects do not come into contact with the upper and lower trays. Sufficient intervals can be secured between them. Further, when the objects to be stored are not stored, the direction of the stacking storage trays can be aligned to narrow the vertical interval during stacking. The space occupancy rate can be reduced by stacking a plurality of sheets to be reused and being sent back to the transport source or stored in a warehouse by stacking with a narrow vertical interval.

  When the object to be stored is an electronic component, the electronic component is taken out from the storage tray by an automatic machine mounted on a printed circuit board or the like. However, when the storage trays are stacked and stored in different directions by 180 ° between the top and bottom, the storage trays must be rotated 180 ° and aligned before the pickup. It takes time and labor.

On the other hand, Patent Document 2 discloses a storage tray that can adjust the interval between the upper and lower sides when they are stacked without rotating 180 °.
The storage tray of Patent Document 2 has a gap forming means that protrudes outward from the outer peripheral edge. The gap forming means includes a bent piece that can be bent inside the side wall portion, and a bent piece that is bent. It is set as the structure provided with the protrusion piece which protrudes inside.

In the storage tray of Patent Document 2, when the folded piece is folded to the outside of the side wall, there is no gap between the stacked storage trays, and the space occupancy can be reduced.
In addition, when the bent piece is bent inward of the side wall, the protruding piece protrudes inside the side wall. The protruding piece comes into contact with the upper end surface of the outer peripheral edge of the storage tray stacked downward. For this reason, the storage trays stacked in the vertical direction are arranged at a predetermined interval without being in close contact with each other.

  As in Patent Document 2, in the storage tray described in Patent Document 2 that can be stacked when not stored without narrowing by 180 ° and the interval between the upper and lower sides is narrowed, the protruding piece is stored in the lower position when stored. Since it is only in contact with the upper end surface of the outer peripheral edge of the tray, there is a problem that the contact area between the upper and lower sides is extremely small and the strength when stacked is low.

  The present invention has been made to solve the above-described problems, and the object of the present invention is to store without changing the orientation of the storage tray between the state in which the object is stored and the state in which the object is not stored. An object of the present invention is to provide a storage tray that can adjust the gap between the upper and lower sides of the tray and can maintain high strength.

According to the storage tray of the present invention, the storage tray has a quadrangular shape in plan view, and a plurality of storage recesses for storing the objects to be stored are formed, outward from the upper ends of the outer peripheral edge portions of the two opposite sides of the four sides. A bent piece extending toward the bottom, and the bent piece is the same as the bottom position of any one of the storage recesses, and the first bent piece that is bent vertically downward at the first bent portion outside the outer peripheral edge. And a second bent portion that is bent so that the front end side of the first bent piece is positioned below the bottom surface of the storage recess.
By adopting this configuration, if the item to be stored is not stored, by keeping the folded piece extended outward, the storage recesses enter each other when stacked in the vertical direction, Stacking is possible with small gaps that are in close contact with each other at the top and bottom, and space occupancy can be reduced. In addition, when storing the objects to be stored, the bent piece is bent at the first bent portion, the first bent piece is positioned vertically downward, and bent at the second bent portion to store the stored tray. A 2nd bending piece can be located inside a bottom face. Therefore, even if the storage trays are not alternately rotated by 180 degrees on the tray plane and stacked, the outer peripheral edge of the storage tray located below is in contact with the lower surface of the second folded piece. Can be stacked with a gap. In addition, since the first folding piece can extend vertically downward to form an outer wall surface, the weight of the upper storage tray is bent vertically downward even when the objects to be stored are stored and stacked. Since it is applied to the piece, deformation due to the weight of the object to be stored can be prevented.

In addition, a fitting portion that detachably fits between the second bent piece and the bottom surface of the storage recess located on the upper surface of the second bent piece when the second bent piece is bent. It is good also as providing.
According to this configuration, when the objects to be stored are stored and stacked, the second bent piece can be securely attached to the bottom surface of the storage recess so as to be detachable. For this reason, when the objects to be stored are stored, it is possible to prevent the folding of the bent pieces from returning to the original state at the first and second bent portions, and the stack can be stacked with a sufficient gap. The shape can be maintained.

Further, the fitting portion is formed in the second bent piece, and is formed in the fitting concave portion that protrudes toward the bottom surface side of the storage concave portion when the second bent piece is bent, and the storage concave portion. It is good also as having a fitting crevice which can store the fitting convex part.
According to this configuration, it is possible to easily attach and detach between the second bent piece and the bottom surface of the storage recessed portion, and it is possible to easily perform the manufacturing.

The first bent piece may be formed with one or more strength maintaining ribs extending downward when the first bent piece is bent.
According to this configuration, the strength-maintaining rib can prevent deformation of the first bent piece due to the weight from the weight of the upper storage tray when the objects to be stored are stored and stacked.

Further, a perforation may be formed in the first bent portion and the second bent portion.
According to this configuration, it is possible to easily perform bending at each bending portion.

  According to the storage tray of the present invention, the gap between the upper and lower storage trays stacked without changing the orientation of the storage tray between the state in which the storage object is stored and the state in which the storage object is not stored. Can be adjusted and high strength can be maintained.

It is a perspective view of the storage tray of the present invention. It is a side view of the bending piece of a storage tray. It is a side view which shows the place which bent the bending piece of FIG. It is a side view which shows the place which piled up the storage tray which bent the bending piece.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view of a storage tray, and FIGS. 2 and 3 are side views of bent pieces of the storage tray. FIG. 4 is a side view of a state in which storage trays in which bent pieces are bent are stacked.

The storage tray 30 is formed by vacuum forming a flat synthetic resin material such as polypropylene, polystyrene, or PET into a rectangular shape in plan view to provide unevenness. A plurality of storage recesses 32 which are recesses for storing (not shown) are formed.
In the present embodiment, the storage tray 30 has a rectangular shape in plan view, but may have a square shape in plan view.

  The storage tray 30 stores the objects to be stored in the storage recess 32 and then is used by stacking a plurality of sheets, and the objects to be stored are stored or transported in the stacked state. In addition, the storage tray 30 is stacked so that there is no gap between the top and bottom until the stored object is taken out and used again. Space occupancy can be reduced by stacking so that there is no gap between the top and bottom.

  An outer wall portion 33 is formed so as to surround the outer periphery of the plurality of storage recesses 32 in the storage tray 30, and a flange portion 34 is formed at the upper end portion of the outer wall portion 33 so as to protrude outward in the horizontal direction. The upper end of the outer peripheral edge referred to in the claims corresponds to the upper end of the outer wall 33 of the present embodiment.

Of the four rectangular sides, a bent piece 40 is formed further outward from the flange portion 34 at two short sides. The bent piece 40 is integrally formed continuously with the flange portion 34.
On the two short sides, a portion extending outward from the upper end portion of the outer wall portion 33 by a predetermined distance is a flange portion 34, and a bent piece 40 is formed at the tip of the flange portion 34. The folding piece 40 is formed with perforations at the first folding position 43 and the second folding position 45 so as to be foldable at the first folding position 43 and the second folding position 45.
However, the 1st bending part 43 and the 2nd bending part 45 are not limited to a perforation, You may form a groove | channel.

Between the first bent portion 43 and the second bent portion 45 is a first bent piece 42. The width w1 of the first bent piece 42 has substantially the same width as the lateral width of the entire storage recess 32. Therefore, the width w1 of the first bent piece 42 is formed to be narrower than the width w2 of the flange 34 by the amount of protrusion of the flange 34 on the long side.
Further, the outwardly protruding length L of the first bent piece 42 is formed to be substantially the same as the height h of the storage recess 32. Therefore, when the first bent portion 43 is bent 90 ° vertically downward, the tip end portion of the first bent piece 42 (that is, the second bent portion 45) reaches the bottom surface position of the storage recess 32.

  Further, a second bent piece 44 is provided on the outer side of the second bent portion 45. After the first bent piece 42 is bent so as to be positioned vertically downward, it is bent 90 ° inward at the second bent portion 45 so that the second bent piece 44 is positioned below the storage recess 32, and the storage recess 32 abuts on the bottom surface.

  Further, the width w2 of the second bent piece 44 is formed to be the same as the width w2 of the flange portion 34. That is, when the second folded piece 44 is disposed on the lower surface of the storage recess 32, the second folded piece 44 is placed on the flange portion 34 of the lower storage tray 30 when stacked in the vertical direction. . As described above, by making the width of the second bent piece 44 the same as the width of the flange portion 34, the stability when stacked can be improved and the strength can be maintained.

The first bent piece 42 is formed with a plurality of strength-maintaining ribs 50 extending downward when the first bent piece 42 is bent.
In a state where the first bent piece 42 is not bent, the rib 50 has a shape that is recessed downward, and is the same as the recessed direction of the storage recess 32. That is, the rib 50 can be easily formed by vacuum forming.

By forming such a rib 50 on the first bent piece 42, when the first bent piece 42 is bent vertically downward, the first bent piece 42 can be prevented from being deformed and the strength can be maintained.
In addition, the rib 50 for intensity | strength maintenance is not limited to being formed in multiple numbers in the 1st bending piece 42, The one rib 50 may be sufficient if intensity | strength can fully be maintained.

  Further, a fitting portion 52 that is detachably fitted to each other is provided between the second bent piece 44 and the bottom surface of the storage recess 32. With such a configuration, the first bent piece 42 and the second bent piece 44 are about to return to the original horizontal position by the elastic force of the material at the first bent portion 43 and the second bent portion 45. In addition, the first bent piece 42 and the second bent piece 44 can be maintained in a state of being bent by being fitted by the fitting portion 52.

  In the present embodiment, as a specific example of the fitting portion 52, a fitting convex portion and a fitting concave portion that can be unevenly fitted are formed. The second bent piece 44 is provided with a fitting convex portion 54 that protrudes upward when being bent at the second folding portion 45, and a fitting concave portion 55 that is recessed upward is formed on the bottom surface of the storage concave portion 32. Has been. By making the diameter of the fitting convex portion 54 slightly larger than the diameter of the fitting concave portion 55, it is possible to prevent the fitting convex portion 54 from easily coming out of the fitting concave portion 55. Moreover, it is preferable not to tighten the fitting state so that it can be easily attached and detached manually.

As shown in FIG. 1, the fitting convex portion 54 may have a circular shape in plan view, and the fitting concave portion 55 may have a rectangular shape in plan view. In this way, even if the diameter of the fitting convex portion 54 is larger than the length of the side of the fitting concave portion 55, the fitting convex portion 54 and the fitting concave portion 55 are completely in close contact with each other. However, it is easy to put on and take off.
Further, a protrusion (not shown) may be provided on the outer wall surface of the fitting convex portion 54 and / or the inner wall surface of the fitting concave portion 55.

The second bent piece 44 is formed with a recess 56 that is recessed downward. The recess 56 is formed as a groove extending in the width direction.
A convex portion 58 that protrudes upward is formed on the inner side of the flange portion 34 at the two short sides. The convex portion 58 is formed extending in the width direction. Further, the convex portion 58 has a size that can be accommodated in the concave portion 56.
In addition, although the recessed part 56 and the convex part 58 are shown in FIG. 1, in other drawings, since it overlaps with another structure, it is abbreviate | omitting.

When the first bent piece 42 is bent at a right angle downward and the second bent piece 44 is bent in the horizontal direction, the concave portion 56 is arranged to be recessed upward. At this time, the convex portion 58 is located immediately above the concave portion 56.
Therefore, when a plurality of storage trays 30 in which the first bent piece 42 and the second bent piece 44 are bent are stacked in the vertical direction, the convex portion 58 of the storage tray 30 positioned below is stored upward. The tray 30 is accommodated in the concave portion 56 of the tray 30 and functions as a positioning of the stacked storage trays.

  The bent piece can be manufactured by molding a portion that should be cut and discarded when vacuum forming. Accordingly, in forming the bent piece, the cost of raw materials and the like is not increased, and the waste loss is reduced, which can contribute to cost reduction.

  In the embodiment described above, the bent piece is formed on the short side of the rectangle, but the bent piece may be formed on the long side of the rectangle. Further, if the storage tray has a square shape in plan view, there is no short side or long side, and therefore bent pieces may be formed on any two opposing sides.

  While the present invention has been described above with reference to a preferred embodiment, the present invention is not limited to this embodiment, and it goes without saying that many modifications can be made without departing from the spirit of the invention. .
