  However, the storage boxes described in Patent Documents 1 to 3 have room for improvement in that it takes time to assemble. That is, there is a case where the assembly of the storage box cannot keep up with the pace even though it is necessary to ship the products manufactured at the food factory from one to the next. On the other hand, when a large number of storage boxes are assembled in advance or an assembled storage box is purchased, it is necessary to secure a space for storing a bulky storage box.

  The present invention has been made in view of the above circumstances, and is a transport tray that is not bulky compared to a conventional storage box or the like even in an assembled state, and can realize high work efficiency at a site such as a food factory. And it aims at providing the blank for manufacturing this.

  A transport tray according to the present invention (hereinafter, simply referred to as “tray” in some cases) is manufactured through a process of bending a single blank, and includes one or a plurality of openings for accommodating a transport target. A top plate having a section, a fold forming the edge of the top plate, and a side plate extending from the fold to the direction away from the top plate, the side plate spreading outward as it moves away from the top plate And the end of the side plate is constituted by the outer edge of the blank.

  The tray is used in a state in which the top plate is disposed on the upper side, and in this state, the tray holds the conveyance target inserted into the opening from above. As described above, the tip of the side edge of the tray is constituted by the outer edge of the blank. This configuration means that the tray does not have a bottom plate and does not have a support plate or the like for reinforcing the top plate. In addition, the side plate of this tray is inclined so as to spread outward as it moves away from the top plate. By adopting these configurations, the other trays can be stacked so as to be fitted in one tray. Therefore, a large number of trays can be stacked in a compact manner, and space can be saved. Thereby, in the field of food factories and the like, a large number of trays can be stored in an already assembled state, not in a blank state, and can be used immediately when necessary, so that high work efficiency can be realized. In addition, the present inventors have arranged a large number of trays in a state where the top plate is facing down (upside down as in normal use), and sequentially use from the top tray, It has been found that the side plate of the tray can be easily picked up with fingers and can contribute to better working efficiency.

  The edge of the top plate may have a plurality of cuts provided along the edge. These cuts may be provided in advance in the blank. In the process of assembling the blank and manufacturing the tray, the crease becomes the edge of the top plate (and the base end of the side plate) by making a crease along the cut. The incision provides the advantage that it is easy to crease when assembling the tray.

  In a state where the tray is placed on a horizontal plane so that the top plate is on the top, it is preferable that the top plate is formed of a curved surface with the center portion protruding upward. The above-described configuration can be realized by performing the pasting in a state where the fold forming the edge of the top plate (and the base end of the side plate) is not completely bent. Such a configuration can be effectively realized by, for example, a portion in which the above-described fold is not provided (a portion between two adjacent cuts). The portion applies tension to the top plate so that the top plate is convex upward. As a result, a repulsive force against the force applied from above is applied to the top plate.

  In a state where the tray is placed on a horizontal plane so that the top plate is on the upper side, the angle formed between the side plate and the horizontal plane is preferably 80 to 84 from the viewpoint of the strength of the tray and the ease of pickup from the stacked state. °.

  What is necessary is just to set the shape of an opening part suitably according to conveyance object, for example, it can be set as the substantially circular shape of diameter 3-10cm. The opening may have a plurality of flaps extending from the inner periphery of the opening toward the center of the opening. By providing the flap in the opening, the flap can be brought into contact with the conveyance target, and the conveyance target can be more stably held.

  Although the aspect of conveyance object is not particularly limited, examples include the following. That is, one aspect of the conveyance target includes a container body having an enlarged portion whose side surface extends from the bottom surface toward the opening and / or a straight body portion that does not widen, and a flange portion projecting outward from the opening.

The present invention provides a blank for manufacturing the tray. This blank is made of, for example, a paper board of 180 to 550 g / m ² .

  According to the present invention, even in an assembled state, it is not bulky compared to a conventional storage box or the like, and a transfer tray capable of realizing high work efficiency at a site such as a food factory, and a blank for manufacturing the same. Is provided.

Two adjacent side plates 3 are bonded to each other at the joint 5 with an adhesive. The four side plates 3 have a fold 7 forming the edge 2b of the top plate 2 as a base end 3a, and are inclined so as to spread outward as the distance from the top plate 2 increases. The front end 3b of the side plate 3 is constituted by the outer edge 1a of the blank 1 (see FIG. 7).

  The tray 10 is used, for example, when a product (conveyance target) 20 such as sweets is transported from a food factory to a convenience store. FIG. 2 shows a state in which the products 20 are set in two of the four openings 2 a of the tray 10. The product 20 has a container 21 that contains the contents. As shown in FIG. 3A, the container 21 includes an enlarged portion 21a and a straight body portion 21b whose side surfaces expand from the bottom surface 22 toward the opening 23, a flange portion 25 projecting outward from the opening 23, a flange And a sheet-like lid 26 bonded to the portion 25. In addition, the container 21 may have only the enlarged part 21a (refer FIG.3 (b)), and may have only the straight body part 21b. The container 21 may employ a plastic lid (not shown) that fits into the flange portion 25 instead of the sheet-like lid 26.

  The goods are transported from the food factory to the convenience store in a state where a plurality of trays 10 are passed through the box 60 as shown in FIG. In addition, the goods 20 conveyed using the tray 10 are not limited to sweets (dessert), A drink, a snack, etc. may be sufficient. The shipping source is not limited to a food factory, and the transport destination is not limited to a convenience store. The tray 10 may be returned to the shipping source together with the return box 60 and reused, or may be disposable.

  As shown in FIG. 1, the tray 10 is used in a state in which the top plate 2 is disposed on the upper side, and in this state, the product 20 is inserted into the opening 2 a from above (see FIG. 2). As shown in FIG. 5, the tray 10 does not have a bottom plate and is not provided with a support plate or the like for reinforcing the top plate 2. In addition, the side plate 3 of the tray 10 is inclined so as to spread outward as it moves away from the top plate 2. By adopting these configurations, the other trays 10 can be stacked so as to be fitted in one tray 10 (see FIG. 6). Therefore, a large number of trays 10 can be stacked in a compact manner, and space saving can be achieved. Thereby, in the field of food factories and the like, a large number of trays 10 can be stored not in the state of the blank 1 but in an already assembled state, and can be used immediately when necessary, thereby realizing high work efficiency. .

The material of the tray 10 is paperboard, and the weight per unit area is preferably 180 to 550 g / m ² , more preferably 270 to 350 g / m ² . When high strength is required for the tray 10, cardboard may be used instead of paperboard.

Although the length of one side of the top plate 2 depends on the size and weight of the product 20, it is preferably 5 to 40 cm, more preferably 10 to 20 cm. From the viewpoint of the strength of the tray 10, the opening ratio of the top plate 2 is preferably about 40 to 60%. The aperture ratio here means a value calculated by the following equation. In the formula, “area of the top plate” includes the area of the opening, and is a value calculated by squaring the length of one side of the top plate 2 (square).
Opening ratio (%) = (total area of openings) / top plate area × 100

  The opening 2a is preferably substantially circular with a diameter of 3 to 10 cm (more preferably with a diameter of 5.3 to 7.2 cm). As shown in FIG. 7, the inner periphery 2 c of the opening 2 a is configured by an arc portion and a part of a linear fold 7. Note that the shape of the opening 2a may be a circle, an ellipse, a polygon, or the like. In addition, the shapes and sizes of the plurality of openings 2a in the tray 10 may all be the same or different, and may be appropriately selected according to the size and the conveyance frequency of the product 20.

  The opening 2a has a plurality of flaps 2f extending from the inner periphery 2c toward the center of the opening 2a. In the present embodiment, six flaps 2f are provided in each opening 2a. By providing the flap 2f in the opening 2a, the flap 2f can be brought into contact with the product 20, and the product 20 can be more stably held during transportation. A perforation 2e is provided at the joint between the inner periphery 2c of the opening 2a and the flap 2f. In addition, the flap 2f is not provided in the part in which the crease | fold 7 comprises the inner periphery 2c. If a flap is provided in the portion, when the side plate 3 is bent with respect to the top plate 2, the flap of the portion rises so as to protrude from the top plate 2, which tends to hinder stacking. . When calculating the opening ratio of the tray 10 having the flap 2f, the area of the opening 2a means an area surrounded by the inner periphery 2c. That is, the presence / absence of the flap 2f does not affect the area of the opening 2a.

  As shown in FIG. 1, the top plate 2 is not a flat surface, but is formed to be convex upward. That is, in a state where the tray 10 is placed on a horizontal surface so that the top plate 2 is on the upper side, the top plate 2 is configured by a curved surface whose central portion is raised upward. This configuration can be realized by pasting the side plates 3 in a state where the fold line 7 is not completely bent. Specifically, the edge 2b of the top plate 2 (the base end 3a of the side plate 3) is provided with a plurality of cuts 7a, and the tray 10 is manufactured through a process of bending the blank 1 along this. . A portion where the notch 7a is not provided (a portion between two adjacent notches 7a) 7b applies tension to the top plate 2 so that the top plate 2 is convex upward. As a result, a repulsive force against the force applied from above is applied to the top plate 2. From the viewpoint of stably obtaining such an effect, the distance between the two adjacent cuts 7a (the length of the portion 7b) is preferably 3 to 20 mm, and more preferably 10 mm. The length of the cut 7a is preferably 3 to 20 mm, more preferably 10 mm.

  The length from the base end 3a to the front end 3b of the side plate 3 depends on the size and weight of the product 20, but is preferably 3 to 10 cm, more preferably 2.5 to 4.5 cm. In a state where the tray is placed on a horizontal plane so that the top plate 2 is on the upper side, the angle formed between the side plate 3 and the horizontal plane is preferably from the viewpoint of the strength of the tray 10 and the ease of pickup from the stacked state. It is 80-84 degrees.

  When the tray 10 is used, as shown in FIG. 6, it is preferable that a large number of trays 10 are stacked with the top plate 2 facing down, and the trays 10 are used sequentially from the top tray 10. If the tray 10 is arranged in this way, the tray 10 can be easily picked up by pinching the side plate 3 with a finger.
