According to the present invention, in a tray main body 1 formed of a large number of recesses 4 for accommodating articles, a partition wall 5, and a peripheral wall 6, the tray main body 1 is formed by a thermohoming method using a thin sheet, The transport tray is characterized in that the bottom surface of the recess 4 and the bottom surface of the peripheral wall 6 are substantially flush with each other, and the bottom plate 2 is abutted and fixed to the back surface of the tray body 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transportation tray used for packing and transporting small articles in various industrial fields.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, for example, trays formed of foamed resin have been used for packaging and transporting small electronic parts, precision small machine parts, and other small articles. This is to provide a plurality of compartments inside the tray that match the size of the stored items, and to raise the peripheral wall of this tray so that the stored items can be accommodated within the peripheral wall.

[0003]

[Problems to be solved by the device]

 In the conventional tray described above, the partition chamber is made of foamed resin in conformity with the size of the small articles to be stored, so there are many partition walls that partition each partition chamber, and inevitably the wall thickness is high in terms of strength. However, there is a drawback that the total storage capacity is large and the actual storage capacity is small with respect to the size of the tray. Further, there is a problem that the occupied volume during the manufacturing process and storage of the tray itself becomes large, and the occupied volume cannot be reduced especially by stacking. The present invention has been made in view of the above circumstances, and an object thereof is to provide a transportation tray that solves the above problems.

[0004]

[Means for Solving the Problems]

 In view of the above object, the present invention is a tray main body formed of a large number of recesses for storing articles, a partition wall, and a peripheral wall. The tray main body is formed by a thermoforming method using a thin sheet, and The above problem is solved by providing a transportation tray in which the bottom rear surface and the lower surface of the peripheral wall are substantially flush with each other, and the bottom plate is brought into contact with and fixed to the bottom surface of the tray body.

[0005]

[Action]

 Since the transportation tray of the present invention is configured as described above, even when the articles are stored in the tray body, the bottom of the many recessed portions of the tray body is supported by the bottom plate, so that the tray becomes strong. , Not easily deformed. In addition, in the case where the tray main body and the bottom plate are sealed, even if the tray main body is deformed, the sealed air inside does not escape to the outside, thereby increasing the cushioning effect and further increasing the resistance to deformation. growing. In addition, the weight can be reduced.

【Example】

 1 to 3 show an embodiment of a transportation tray according to the present invention. In the figure, 1 is a tray body, and 2 is a bottom plate fixed to the entire bottom surface of the tray body 1. The tray body 1 comprises a large number of recesses 4 for accommodating articles, a partition wall 5 for these, and a peripheral wall 6. These are formed by a thermoforming method such as a vacuum forming method using a thin plate of synthetic resin. is there. Therefore, when the tray main body 1 is viewed from the back side, the recess 4 surrounds the protrusion 4a, the partition wall 5 surrounds the recess 5a, and the peripheral wall 6 surrounds the recess 6a. The two protrusions 4a on the bottom of the recess 4 shown in FIG. 3 are for matching a pair of protrusions of the article to be housed. It goes without saying that the two protrusions may be omitted so that they are flush with each other. Further, the forming of the tray body is not limited to the vacuum forming method, but thermoforming methods such as the pressure molding method, the multi-die molding method and the drawing method are used. The tray body 1 uses a thin synthetic resin sheet (for example, a thickness of 0.2 to 0.8 mm) as described above. As the resin material, for example, high-impact polystyrene (HiPS), polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE) and other similar materials are used. The breathable material may be used as a non-breathable material by stacking it in multiple layers.

The bottom plate 2 is made of cardboard, cardboard, veneer plate, synthetic resin film or sheet having an appropriate thickness and predetermined rigidity. Examples of the synthetic resin material include high impact polystyrene (HiPS) and polypropylene. (PP), polyvinyl chloride (PVC), polyethylene (PE), nylon (NY), polyethylene terephthalate (PET) and other similar materials are used. The projection 4a of the tray body 1 and the lower end surface 6b of the peripheral wall 6 are formed so as to be on the same plane P, and when the bottom plate 2 is applied, the projection 4a and the lower end surface 6b of the peripheral wall 6 are formed. Are configured to abut the bottom plate 2.

The tray body 1 and the bottom plate 2 have their contact surfaces fixed to each other by a predetermined method. For example, an adhesive is applied to the abutting surface, or if a synthetic resin material is used for the bottom plate 2, heat sealing or ultrasonic welding is used to appropriately fuse and seal. FIGS. 4 and 5 show another embodiment, in which the corrugated cardboard 21 or a thin film or hard plate 22 is abutted and fixed to the tray body 11 or 12. Depending on the state of use, the lower surface of the peripheral wall of the tray main body and the peripheral edge of the bottom plate may be heat-sealed to complete sealing.

At the time of use, the articles may be housed in the respective recesses in the same manner as in the conventional Styrofoam transportation tray, and the articles may be stacked in an appropriate container, for example, a cardboard box or the like, and then packed. . FIG. 6 shows the usage procedure thereof, in which the transport trays 1 (or 11, 12) accommodating the articles 9 are sequentially stacked in the corrugated cardboard box 8. Since the stacked transport trays have rigid bottom plates that are provided at regular intervals, the packaging box itself made of corrugated cardboard becomes extremely strong, and the tray body and bottom plate are completely sealed. In this case, the sealed air inside serves as a cushion to provide complete protection for the contained items.

[0010]

[Effect of device]

 As described above, according to the present invention, the tray main body is manufactured by the thermoforming method using a thin sheet of synthetic resin, and the bottom rear surface of the recess for accommodating articles and the bottom surface of the peripheral wall of the tray are substantially flush with each other. The bottom plate is abutted and fixed on the back surface of the tray body. That is, since the tray body is molded using an extremely thin sheet as described above, it occupies less space than the conventional foamed resin and has good workability and productivity in the manufacturing plant. At the same time, it will be possible to reduce transport costs and automate assembly. In addition, after fixing the bottom plate to the tray body, a moderate rigidity can be obtained and a soft cushioning effect can be obtained.
