  Conventionally, articles to be packed such as parts of industrial machines, vehicle parts, or electronic parts are packed and transported by a packing tray. The packing tray is formed with a storage recess for storing the packaged object according to the shape of the packaged object. In a state where the articles to be packed are stored in the storage recesses of such a packing tray, they are stacked in the vertical direction and conveyed as a package. In this way, a plurality of items to be packed can be transported simultaneously.

  For example, a packaging tray for storing a long packaged object, in which a plurality of storage recesses deeper than the packaged object are arranged on the upper surface of the packaging tray, is proposed. (For example, refer to Patent Document 1). By using such a packing tray, a plurality of items to be packed can be stored and a plurality of packing trays storing the items to be packed can be easily stacked in the vertical direction.

JP 2008-260579 A

  When a packaging tray such as that disclosed in Patent Document 1 is used, the depth of the storage recess is greater than the height of the packaged object, so even if the packaged object is stored in the storage recess, the packaged object is opened from the opening of the storage recess. Will not pop out (protrude).

  However, for example, when the height of the object to be packed becomes higher than the conventional one, a storage recess having a depth corresponding to this must be provided. Therefore, the thickness of the wall portion that forms the storage recess is reduced, and the strength of the packaging tray may be reduced.

  In addition, when the packing trays are stacked in the vertical direction with the packaged items stored, the height of the stacked packaging trays (packaging bodies) also increases as the height of the packaged items increases. It will increase.

  The present invention has been made in view of these points, and the object of the present invention is to provide a packaging tray that can be stacked in a vertical direction while ensuring the strength of the packaging tray. It is to propose.

  In view of the above problems, the packing tray according to the present invention has a plurality of storage recesses for storing at least a part of an object to be packaged, and the storage recesses are directed upward and downward. A packing tray for packing the objects to be packed by stacking in a direction, wherein each of the storage recesses is formed on the lower side of the packing tray so that a bottom protrusion is formed on the lower surface side of the packing tray. When the upper and lower stacking is performed by inverting the lower packaging tray with respect to the upper packaging tray, which is molded on the upper surface side, Each of the storage recesses is formed between the bottom protrusions of the tray so that the storage recesses of the lower packaging tray are disposed.

  According to the present invention, when an object to be packed is stored in the storage recess of the packing tray, the upper portion of the object to be packed protrudes (protrudes out) from the storage recess. And the several tray for packing in the state which accommodated the to-be-packaged item is stacked up and down. Specifically, with the storage recess of each packing tray facing upward, the packing tray positioned at the lower position is inverted with respect to the packing tray positioned at the upper position, and each packing tray is moved vertically. Pile up to.

  At this time, each storage recess is formed so that the storage recess of the lower packaging tray is disposed between the bottom protrusions of the upper packaging tray. The upper part of the object to be packed that protrudes from the opening of the storage recess of the packing tray to be inserted can enter between the bottom protrusions of the packing tray positioned at the upper level.

  In this manner, the packing trays with a part of the objects to be packed protruding from the storage recesses can be stacked in the vertical direction in a compact manner. In addition, since the objects to be packed positioned up and down by the stacking do not come into contact with each other via the tray, it is not necessary to provide a storage recess deeper than the height of the objects to be packed. Thereby, the wall part of a storage recessed part is not restrict | squeezed excessively at the time of shaping | molding, but it can ensure the intensity | strength of the packaging tray.

  In this way, by making the structure so that the upper part of the article to be packed popped out from the opening of the storage recess of the packaging tray located in the lower part enters between the bottom protruding parts of the packaging tray located in the upper part, Other structures are not particularly limited as long as packing trays can be stacked in the vertical direction in a compact manner.

  However, as a more preferable aspect, when the packing tray located in the lower position is inverted with respect to the packing tray located in the upper position and the stacking in the vertical direction is performed, the lower position is positioned in the lower position. Each of the storage recesses is formed on the upper surface between the storage recesses of the packing tray so that the bottom protruding portion of the packing tray positioned above is supported.

  According to this aspect, when the packaging trays are stacked in the vertical direction, the upper surface of the lower packaging tray supports the bottom protruding portion of the packaging tray. Misalignment and deformation can be suppressed.

  As a more preferable aspect, the storage recess has a depth that allows storage of half or more of the height of the packaged object. By using the storage concave portion having such a depth, the upper portion of the packaged object that protrudes from the opening of the storage concave portion of the lower packaging tray comes into contact with the bottom surface (lower surface) of the upper packaging tray. The bottom protrusion part of the packaging tray can be supported on the upper surface of the packaging tray positioned below.

  Furthermore, as a more preferable aspect in the case where a projection is formed on the side surface of the packaged object, a holding recess for holding the projection is formed on the side wall forming the storage recess. By providing such a holding recess in the side wall of the storage recess, it is possible to hold an object to be packed in the storage recess.

  Thus, a package can be obtained by storing an object to be packed in the above-described packing tray and stacking the packing tray in the vertical direction.

  According to the present invention, the packing tray can be stacked compactly in the vertical direction while ensuring the strength of the packaging tray.

Below, two embodiment of the packaging tray which concerns on this invention is described based on drawing.
[First Embodiment]
FIG. 1 is a schematic perspective view for explaining a packing body when an object to be packed is stored in a packing tray according to a first embodiment of the present invention. 2 is a schematic conceptual view of the packaging tray shown in FIG. 1, (a) is a top view of the packaging tray, and (b) is a cross-sectional view taken along line AA in (a). . 3A is a schematic cross-sectional view in a state where the packaging trays shown in FIG. 1 are stacked, and FIG. 3B is a schematic cross-sectional view in the vicinity of the storage recess shown in FIG.

  FIG. 4A is a schematic cross-sectional view of the packaging tray according to another aspect in a stacked state, and FIG. 4B is a schematic cross-sectional view of the vicinity of the storage recess shown in FIG.

  As shown in FIGS. 1 to 3, the packing tray 10 according to the first embodiment is a tray for packing a long packaged object P. The packing tray 10 is used by being stacked in a plurality of stages in the vertical direction. As shown in FIG. 1, by packing two packing trays 10 </ b> A and 10 </ b> B vertically in a state where a plurality of items to be packed P are packed in two packing trays 10 </ b> A and 10 </ b> B, Is done.

  In addition, 10A is attached | subjected to the code | symbol of the packaging tray located in the upper rank, and 10B is attached | subjected to the code | symbol of the packaging tray located in the lower rank among the packing trays stacked up and down shown in FIG. These packing trays 10A and 10B are packing trays having the same shape. When describing the positional relationship between the upper and lower sides of the packing tray, the symbols 10A and 10B are used, and when the packing tray alone is described, the symbol 10 is used.

  Each of the packing trays 10 is formed by integrally molding a sheet-like thermoplastic resin, for example, by a thermoforming means such as vacuum forming. Examples of the material include polyolefin resins such as polypropylene (PP) and polyethylene (PE), polystyrene (PS) resins such as impact-resistant polystyrene (HiPS), or polyester resins such as polyethylene terephthalate (PET). The material is not particularly limited as long as it is a resin that can be thermoformed.

  As shown in FIGS. 1 and 2 (a) and 2 (b), the packing tray 10 can be stacked in the vertical direction along the vertical direction so as to surround the peripheral edge portion 10b of the upper surface 10a. A wall portion 10c that is slightly inclined and rises outward is formed. By providing the wall portion 10c, the upper surface 10a of the packing tray 10 and the wall portion 10c form a recess for accommodating the bottom portion 10e of the packing tray 10A positioned at the upper level.

  When the packaging trays 10A and 10B are stacked in the vertical direction, the bottom portion 10e of the packaging tray 10A located at the upper position is disposed along the wall portion 10c of the packaging tray 10B located at the lower position, The packaging trays 10A and 10B can be positioned.

  Further, a flange portion 10d is formed around the wall portion 10c. By gripping the collar 10d by the operator, the packing tray 10 can be easily lifted up and the packing trays 10A and 10B can be easily moved in the vertical direction even if the article to be packed P is packed (stored). Can be stacked.

  On the upper surface 10a side of such a packing tray 10, six rows (plurality) of storage recesses 11 for storing the above-described long items to be packed are formed. The depth D of the storage recess (storage groove) 11 is smaller than the height H of the article to be packed P (D <H). As a result, the upper part pt of the article to be packed pops out (protrudes) from the opening 11 a of the accommodation recess 11 in a state where the article to be packed P is stored in the storage recess 11.

  As described above, since the packing tray 10 is formed from a sheet-like resin, when each storage recess 11 is formed on the upper surface 10a side of the packing tray 10, the packing tray 10 at a position corresponding to this is formed. A bottom protrusion 12 is formed on the lower surface side.

  As shown in FIGS. 1 and 2A, the plurality of storage recesses 11 of the packaging tray 10 are formed at regular intervals (at equal intervals) along the (groove) width direction. . More specifically, the storage recesses 11 formed at equal intervals are formed offset from the center line CL of the packing tray 10 by a certain amount on the side along the groove width direction. That is, the storage recess 11 is formed asymmetrically with respect to the center line CL of the packing tray 10.

  And in the state which turned the storage recessed part 11 upwards, the to-be-packed goods P are stored in each storage recessed part 11, and the packaging tray 10B located in the lower position is reversed with respect to the packing tray 10A located in the higher order. As shown in FIG. 1, vertical stacking is performed. In this stacked state, each storage recess 11 is arranged so that the storage recess 11 of the lower packaging tray 10B is disposed between the bottom protrusions 12 and 12 of the upper packaging tray 10A. It is formed.

  Thus, as shown in FIGS. 1 and 3A, when the article P is stored in the storage recess 11 of the packing tray 10, the upper part pt of the package P projects from the storage recess 11. (Jumps out). And the packing trays 10 and 10 in a state where a plurality of articles to be packed P are stored are stacked in the vertical direction. Specifically, the packing tray 10B positioned at the lower position is inverted with respect to the packing tray 10A positioned at the upper position with the storage recess 11 of each packing tray 10 facing upward, Packing trays 10A (10B) are stacked vertically.

  At this time, each storage recess 11 is formed such that the storage recess 11 of the lower packaging tray 10B is disposed between the bottom protrusions 12 and 12 of the upper packaging tray 10A. Therefore, the upper part pt of the article P to be packed that protrudes from the opening 11a of the storage recess 11 of the packaging tray 10B positioned at the lower position is between the bottom protrusions 12 and 12 of the packaging tray 10A positioned at the upper position. Will get in.

  In this way, the packing tray 10 in a state where the upper part pt of the article to be packed P protrudes from the opening 11a of the storage recess 11 can be compactly stacked in the vertical direction. Further, since the upper part pt of the lower packaged item P is not in direct contact with the upper bottom protrusion 12 in the state where the packaged item P is stored, the depth deeper than the height H of the packaged product P. The storage recess 11 having the length D may not be provided. Thereby, since it is not necessary to shape | mold the depth D of the storage recessed part 11 more than the height H of the to-be-packaged goods P, the mechanical strength of the packaging tray 10 shape | molded is securable.

  Further, in the present embodiment, as shown in FIG. 4A, the packing tray 10B positioned at the lower position is inverted with respect to the packing tray 10A positioned at the upper position, and the stacking is performed in the vertical direction. In some cases, each of the storage recesses 11 is arranged such that the bottom protrusion 12 of the upper packaging tray 10A is supported on the upper surface 10a between the storage recesses 11, 11 of the lower packaging tray 10B. Is formed.

  Thus, when the packaging trays 10 and 10 are stacked in the vertical direction, the upper surface 10a of the packaging tray 10B positioned at the lower side supports the bottom protrusion 12 of the packaging tray 10A positioned at the upper level. The positional deviation and deformation of the packaging tray 10A located at the upper level can be suppressed.

  Further, as shown in FIG. 3B, the storage recess 11 has a depth D that is half or more of the height H of the article P to be packed. By using the storage concave portion 11 having such a depth D, the upper portion pt of the article P to be packed that protrudes from the opening 11a of the storage concave portion 11 of the packaging tray 10B positioned at the lower position is the packaging tray 10A positioned at the upper position. 3 (see FIG. 3A), and the upper surface 10a of the lower packaging tray 10B supports the bottom protrusion 12 of the upper packaging tray 10A. can do.

  Further, when the article to be packed P is not stored in the packing tray 10, the packing tray 10 is stacked in the vertical direction without being inverted, so that the packing recess 10 of the packing tray 10 </ b> B positioned at the lower position is placed. The bottom protruding portion 12 of the packaging tray 10A located at the upper level enters. Thereby, a plurality of packing trays 10, 10... Can be stacked and stored in the vertical direction without being bulky.

  On the other hand, as in the modification shown in FIG. 4B, the storage recess 11 may have a depth D that is less than half the height H of the article P to be packed. In this case, the upper part pt of the article P to be packed that protrudes from the opening 11a of the storage recess 11 of the packaging tray 10B positioned at the lower position directly connects the bottom surface (lower surface) 10f of the packaging tray 10A positioned at the upper position. I will support it.

  By adopting such a structure, even when an impact load in the vertical direction acts on the packing body 1 when the packing object P is transported as the packing body 1, the upper and lower packing trays 10A, 10B Since the object P is pressed down, it is possible to prevent the packaged object P from jumping out of the storage recess 11 due to the impact load.

The detailed explanation is omitted.

  The packing tray 10C according to the second embodiment is a tray for packing different packages P1 and P2 as shown in FIGS. 5 (a) and 5 (b). Specifically, the packaged item is longer than the first packaged product P1 shown in FIG. 5A and the first packaged product P1 as shown in FIG. 5B. It is composed of a second article to be packed P2 having a short length in the longitudinal direction and having a protrusion pa on the side surface.

  As shown in FIGS. 6A to 6D, the packing tray 10 </ b> C has a plurality of storage recesses (storage grooves) 21 at the same position as in FIG. 1. The length in the longitudinal direction of each storage recess 21 is substantially the same as the length in the longitudinal direction of the first article to be packed P1. Thereby, the 1st to-be-packaged goods P1 can be accommodated in the accommodation recessed part 21 in the state with almost no clearance gap in a longitudinal direction (refer Fig.6 (a)).

  Further, as shown in FIGS. 6A and 6D, a holding recess 23 for holding the projection pa of the second packaged item P2 is formed on the side wall 21a forming the storage recess 21. ing. By providing such a holding recess 23 with the side wall 21a of the storage recess 21, even when the gap S is formed in the longitudinal direction when the second article to be packed P2 is stored in the storage recess 21, the protruding portion Pa is held in the holding recess 23 (see FIG. 6D). Thereby, it can prevent that the 2nd to-be-packaged goods P2 shifts along the longitudinal direction of the accommodation recessed part 21. FIG.
