In particular, the collective packaging container 1 according to the present invention is suitable for accommodating a shallow tray container. In recent years, a shallow tray as shown in FIG. 9A has come to be used in order to store strawberries and the like in a single stack in a visually appealing manner. This shallow tray is characterized in that it has a lower height, a wider length and a wider width, and a shorter flange portion than the ordinary tray shown in FIG. 9B. Further, the side wall of the tray is formed so as to be inclined from the opening portion toward the bottom surface so that the opening area becomes smaller. Examples of such shallow trays include those having a length of 140 to 180 mm, a width of 80 to 120 mm, and a height of 20 to 40 mm. Specifically, a flat tray packed with strawberries [flange The length between the ends of the parts (the length in the long side of the tray) is about 196 mm, the width (the length in the short side of the tray) is about 128 mm, and the height from the lower end of the flange to the lower end of the bottom is about 23 mm. ] Is mentioned. In order to efficiently store such a shallow tray in the collective packaging container and improve the transportation efficiency, the height of the collective packaging container should be made lower than the conventional height in accordance with the shallow tray. preferable. From this point of view, the height (H) of the box body is preferably 58 to 75 mm, more preferably 60 to 70 mm, from the viewpoint of transportation efficiency.

Further, from the viewpoint of transportation efficiency, the above-mentioned collective packaging container is loaded in parallel on the commonly used pallet of 1200×1000 mm as shown in FIG. ) Is preferably 560 to 610 mm, and more preferably 580 to 603 mm. If the side wall step portion is formed on the short side wall of the box body and the side wall step portion is formed so as to support the flange portion of the tray, the strength of the side wall can be improved and the box body can be improved. The length in the longitudinal direction of the can be shortened. Further, the length (W) in the lateral direction of the box body is preferably 350 to 390 mm, more preferably 360 to 380 mm. Further, the ratio (H/L) of the height (H) of the box body to the length (L) in the longitudinal direction of the box body is preferably 0.1 to 0.2, and 0.11 to 0. It is more preferably 0.15.
As for the height (H) of the box body, as shown in FIG. 5A, the height from the bottom wall lower surface to the side wall upper surface of the collective packaging container is measured. As for the length (L) in the longitudinal direction and the length (W) in the lateral direction of the box body, as shown in FIG. 2, the outer dimensions of the collective packaging container are measured.

On the side wall 2 forming the box body, two substantially rectangular ventilation parts 3 are formed on the side wall 2a in the longitudinal direction of the box body and one on the side wall 2b in the lateral direction of the box body. .. From the balance of cooling efficiency and strength as a side wall, the opening ratio of all the ventilation parts 3 to all the side walls 2 is preferably 10 to 60%, more preferably 15 to 50%, and 17 to 17%. It is particularly preferably 30%. Further, cutout recesses 4 serving as handles are formed near the center on the outer surface side of the side wall 2b in the lateral direction, and the band is provided at two corresponding positions on the upper end of the side wall 2a in the longitudinal direction. A shallow concave portion 5 is formed as a mark for hooking.

The inside of the box body has a total of six trays by a side wall protrusion 20 provided so as to project from the side wall of the box body toward the inside of the box body, and a central convex portion 7 provided at the center of the box body. It is divided into a storage part 8. The six tray accommodating portions 8 are arranged such that the trays are arranged in two rows and three trays are arranged in the longitudinal direction of the box body. One of the two rows formed in the longitudinal direction of the box body has a tray. One tray storage portion 8a whose long side direction is oriented in the lateral direction of the box, and two tray storages whose subsequent long side direction is oriented in the longitudinal direction of the box Two tray storage portions 8b are formed so as to line up with the portion 8b, and the long side direction of the tray storage portions is oriented in the longitudinal direction of the box body in the other row, and the following long side direction of the tray storage portions. Is divided by the side wall protrusion 20 and the central protrusion 7 so that one tray storage portion 8a oriented in the lateral direction of the box is aligned.

The side wall protruding portion 20 and the central convex portion 7 are formed so as to support the side wall portion or the flange portion of the tray and accommodate the tray. The tray is preferably held in a suspended state. Since the side wall portion of the tray is inclined from the upper surface side to the lower surface side, it is possible to bring the side wall portion of the side wall protrusion 20 and the central convex portion 7 into contact with the side wall portion of the tray for support. Further, the flange portion of the tray may be placed and supported on the upper surfaces of the side wall protruding portion 20 and the central protruding portion 7. Further, the tray can be stored in the tray storage portion 8 by combining the support on the side wall portion of the tray and the support on the flange portion of the tray.
Regarding the method of supporting the tray in the side wall step portion 6 which will be described later, the tray can be supported in the same manner as in the case of the side wall projecting portion 20 and the central convex portion 7.
From the viewpoint of improving the cushioning property, it is preferable that the side wall projecting portion 20, the central projecting portion 7 and the step portion 6 are formed so as to support the flange portion of the tray. Hereinafter, a mode for supporting the flange portion of the tray as in the illustrated embodiment will be described.

In the illustrated embodiment, side wall step portions 6a having an L shape in a top view are formed on the side wall of the box body, on the side wall inner surfaces of the four corners of the box body, respectively. Further, on the inner surface side of the side wall 2a in the longitudinal direction, two side wall step portions 6b are formed along the side wall at positions offset from each other, and also on the inner surface side of the side wall 2b in the lateral direction. One side wall step portion 6c is formed along the side wall at a position offset between the side walls in the lateral direction facing each other. The side wall protrusions 20a, 20b are formed so as to protrude from the side wall step portions 6b, 6c forming the side walls toward the inside of the box body. Further, the side wall protruding portion 20 divides the inside of the box body into six tray storage portions. Since the side wall step portion 6 is formed as described above, the strength of the side wall can be improved and the flange portion of the tray can be supported. The side wall step portion 6 is preferably formed so as to support the flange portions at at least four corners of the tray, and at least the side wall step portion 6a having an L shape in a top view of the four corner portions of the box is formed. Is preferred. Further, it is preferable that the height of the side wall step portion 6 and the side wall protrusion portion 20 protruding from the side wall step portion are designed in consideration of the support of the flange portion of the tray.
When the side wall step portions 6b and 6c are not formed, the side wall protruding portion 20 is formed so as to protrude from the side wall 2 toward the inside of the box body.

Further, two central convex portions 7a and 7b are formed in the central portion of the box body. It is preferable that the central protrusions 7a and 7b have central protrusions 30a and 30b provided so as to protrude toward the outside of the box toward the side wall protrusion 20. The central protruding portion 30 is preferably formed so as to protrude toward the side wall side in the longitudinal direction of the box body so as to at least form the four corners of the tray housing portion 8 and divide the inside of the box body. In addition, since the central convex portion 7 is formed, the flange portion of the tray can be supported. At this time, the central convex portion 7 is preferably formed so as to support the flange portions at at least four corners of the tray. Further, in consideration of this, it is preferable that the height of the central protrusion 7 and the height of the central protrusion 30 protruding from the central protrusion are designed.
In addition, through holes 10a and 10b may be formed in the central portions of the central convex portions 7a and 7b for stealing meat. Further, since the bottom wall is formed between the central convex portions 7a and 7b formed in the central portion of the box body, the box body has a structure in which it is difficult to bend. Further, projections 9a and 9b as shown may be formed on the respective upper surfaces of the central convex portions 7a and 7b, and if such projections 9 are formed, the tray T accommodated is displaced. Can be prevented.

In the illustrated embodiment, the inside of the box body is formed by the side wall protrusions 20a, 20b and the central protrusions 30a, 30b forming the central protrusions, and one row is arranged in the long side direction of the tray storage portion. One tray accommodating portion 8a oriented in the lateral direction of the box body and two tray accommodating portions 8b in which the long side direction of the subsequent tray accommodating portions are oriented in the longitudinal direction of the box body are arranged, and the other tray accommodating portion 8b is arranged. The row has two tray storage parts 8b in which the long side direction of the tray storage part is oriented in the longitudinal direction of the box body, and one long side direction of the following tray storage parts is oriented in the lateral direction of the box body. The tray storage portions 8a are divided into 6 tray storage portions 8 in total.

In the present invention, the side wall height of the box body is lower than in the conventional case. When the height of the side wall is reduced, particularly in a container made of a foamed body having a substantially rectangular parallelepiped shape like the above-mentioned box body, the box body itself is easily bent and the box body is easily damaged. Furthermore, when the box body is bent, the side wall protrusion 20 and the central protrusion 7 (including the case where the central protrusion 30 is formed on the central protrusion 30; the same applies to the following) applies to the tray flange. When the tray is supported in the air and the tray is suspended in the air, the flange portion of the tray may be easily separated from the side wall protruding portion 20 or the central protruding portion 7. On the other hand, by arranging the tray storage portion 8 in a specific arrangement as described above, the side wall protruding portion 20 and the central protruding portion 7 can function as a reinforcing rib against the force such as the bending and the twist.
For example, the side wall protrusion 20a formed on one side wall in the longitudinal direction is formed at a position displaced from the side wall protrusion 20a formed on the other side wall in the longitudinal direction. When the side wall protrusion is formed at such a position, the side wall protrusion can be formed at a position without deviation, and when a force such as twisting the box is applied, such a force is not applied. It becomes easy to function as a reinforcing rib which resists against. Further, the central convex portions 7a and 7b are also formed at positions displaced in the longitudinal direction, and the same effect as a reinforcing rib can be obtained. In particular, from the viewpoint of strength against bending of the box body, it is preferable to provide the central protrusions 30a and 30b formed toward the side wall protrusions 20.
Further, from the above viewpoint, it is preferable that the tray storage portions 8 are arranged so as to be point-symmetric with respect to the center point of the bottom wall of the box body. When the tray storage portion 8 is arranged in this way, the side wall projections 20 and the central projections 7 that partition the tray storage portion are also formed point-symmetrically with respect to the center of the box body, and thus as a reinforcing rib. The effect of is easily exhibited.

As shown in FIG. 7, the side wall projecting portion 20 and the central convex portion 7 are arranged so as to support the flange portion F of the packed strawberry packed tray T. At this time, the tray T is preferably supported by the side wall protrusions 20 and the central protrusions 7 in the container 1 in a suspended state (a state where the bottom surface of the tray does not contact the bottom wall). Is preferably designed. Generally, it is preferable that the height of the side wall protrusion 20 and the height of the central protrusion 7 are formed about 1 to 5 mm higher than the height from the bottom surface of the tray to be housed to the flange portion.

It should be noted that if the side wall protrusion 20 and the central protrusion 7 are formed continuously, the strength increases, but the passage of cold air deteriorates. Therefore, it is preferable that the side wall protruding portion 20 and the central protruding portion 7 are intermittently formed at least at the portions supporting the flange portions F of the four corner portions of the tray T. Furthermore, by supporting the tray T at the four corners, the tray can be stably supported, and it is possible to prevent the tray from falling from the protruding portion or the like and damaging the fruit due to vibration or the like during transportation.

Further, in the tray storage portion 8, the flange portion F of the tray is preferably supported at the four corners of the tray, and is supported by the side wall protruding portion 20, the central protruding portion 7 (including the central protruding portion 30), and the side wall step portion 6. Preferably. In addition, the side wall projections 20 and the central projections 7 (the central projections 30 are referred to as the central projections 30) supporting the tray flange portion with respect to the peripheral length of the tray storage portion 8 (the length indicated by the chain double-dashed line in FIGS. 1 and 3). The ratio of the total length of the side wall step portions 6 (total length Y shown by dotted lines in FIGS. 1 and 3: Y) is preferably 40 to 90%, and 60 to 85%. Is more preferable. Within the above range, the flange receiving area is sufficient, and it is possible to withstand vibrations during transportation, and also the cold air can pass through. From the viewpoint of strength against bending of the box body and air permeability, it is preferable that the central protruding portion 7 has a central protruding portion 30, and the central protruding portion 30 is formed toward the side wall protruding portion 20. The interval (width of the space portion) between the portion 30 and the side wall protruding portion 20 is preferably 30 to 90 mm, more preferably 40 to 80 mm.

Further, it is preferable that the side wall protrusion 20 has a width of an upper surface of the side wall protrusion [width of a portion supporting the flange portion of the tray (see FIG. 5B): R] of more than 10 mm, It is more preferably 12 to 40 mm. Within the above range, the tray can be more stably held in a suspended state and the strength of the side wall can be effectively reinforced. Further, the side wall protruding portion 20, the central protruding portion 7, and the central protruding portion 30 have a tapered shape that expands from the upper surface side to the lower surface side, which improves the strength as a rib for preventing the bending of the box body. Therefore, the inclination angle (angle with respect to the vertical plane) is preferably 0.5 to 5°.

The side wall thickness (T) of the box body is preferably 15 to 30 mm, and more preferably 17 to 25 mm. The side wall thickness may be different between the longitudinal side wall 2a and the lateral side wall 2b. In that case, the longitudinal side wall thickness should be thicker than the lateral side wall thickness. However, it is preferable from the viewpoint of strength and the viewpoint that the length (L) in the longitudinal direction of the box body can be shortened. Further, when the side wall step portion 6 is formed on the side wall, the width of the upper surface of the step portion (see FIG. 5A): Q] is preferably more than 6 mm, preferably 10 to 20 mm. More preferable.
In addition, the said side wall thickness (T) shall measure the thickness of the part which the side wall step part 6 and the side wall protrusion part 20 do not exist. Specifically, as shown in FIG. 5B, the thickness of a portion of the side wall where no protrusion is provided and which is 1/2 height from the lower end of the portion is measured.

Arc-shaped notches 11 into which a finger can be inserted are formed on the inner surface of the side wall 2a in the longitudinal direction where the ventilation part 3 is formed, and the finger is inserted using the notch 11. Then, the flange portion F of the flat tray T stored and held in the suspended state is picked up, and the tray can be easily taken out from the container 1.

Through holes 13 are formed in the bottom wall 12 forming the box. The through hole 13 is formed in each of the bottom wall portions of the six tray accommodating portions 8 defined by the side wall protruding portion 20 and the central protruding portion 7. It is preferable that the through hole 13 has a quadrangular shape and is formed in the central portion of the bottom surface of the tray when the tray is placed. Specifically, it is particularly preferable that the length is 120 to 186 mm, the width is 70 to 123 mm, the length is 150 to 180, and the width is 85 to 120 mm. Further, the ratio of the area of the opening of the through hole 13 to the area of the bottom wall portion of the partitioned tray housing portion 8 is preferably 50 to 80%, and particularly preferably 55 to 75%. Within this range, even when the flat tray bends due to the weight of the strawberries or moves up and down due to vibration during transportation, the tray bottom does not contact the bottom wall, and damage to the strawberries can be suppressed. In particular, in the case of a shallow flat tray, the bottom of the tray easily bends when storing fruits such as strawberries, and when the tray is suspended in air, the bottom wall of the box and the center of the bottom of the tray make contact. Therefore, from the viewpoint of preventing contact of the bottom surface of the tray and improving cooling efficiency for ventilation, it is preferable that the through hole 13 is formed in the tray housing portion. When the through hole 13 is formed, the strength of the box body tends to be weakened, so that the reinforcing effect of the side wall protrusion 20 and the central protrusion 7 formed at specific positions becomes more remarkable.

The thickness of the bottom wall 12 is preferably 5 to 25 mm, and particularly preferably 10 to 20 mm, from the viewpoint of the balance between the cushioning property and the strength of the bottom wall.

L-shaped engaging projections 14 are formed on the upper surfaces of the side walls of the four corners of the box, and the bottom projections of the bottom of the four corners of the box are engaged with the engaging projections 14. L-shaped engaging recesses 15 are formed respectively. By engaging the engaging projections 14 of the lower container 1 with the engaging recesses 15 of the upper container 1, the containers 1 can be stably stacked in multiple stages as shown in FIG.

The length of the outer peripheral edge of each of the L-shaped engagement protrusions 14 is preferably 40 mm or more. Within the above range, the upper and lower boxes can be sufficiently fitted to each other, and the collective packaging containers can be stacked without the boxes being displaced or the strength being lowered. Further, the height of the engaging projection 14 is preferably 2 to 30 mm, more preferably 5 to 20 mm, and particularly preferably 8 to 15 mm. Within the above range, the engagement is sufficient, the upper and lower boxes are not displaced when the boxes are piled up, and the strength of the protrusion itself is not lowered and the boxes are not easily chipped.

Since the above-mentioned shallow recessed portion 5 serving as a mark for hooking the band P is formed at the upper end of the side wall 2 forming the box body, the shallow recessed portion for hooking the band P is stacked by stacking two or three containers. It is also possible to use 5 for banding and make it easy to carry. The length of the recess 5 is preferably 1 to 80 mm, more preferably 2 to 50 mm, particularly preferably 3 to 40 mm. Within the above range, the receiving area does not decrease. The depth of the recess is preferably 0.3 to 5 mm, more preferably 0.5 to 3 mm, and particularly preferably 0.5 to 2 mm. Within the above range, the handleability will be excellent.

There is no limitation on the thermoplastic resin constituting the collective packaging container according to the present invention having the above-mentioned configuration, for example, styrene resin such as rubber-modified polystyrene or polystyrene, olefin resin such as polyethylene resin or polypropylene resin, or the like. A general-purpose resin and a composite resin of polystyrene and polyethylene are exemplified, and among these, a styrene-based resin is preferable because it is easily foamed highly and has high rigidity. Further, as the form of the foamed molded body, since the above-mentioned complicated shape and a container having a large shape can be easily manufactured, the foamed particles are filled in a mold of a predetermined shape and heat-molded by steam or the like, A foamed particle molded body obtained by fusing the foamed particles is preferable.

When the collective packaging container of the present invention is composed of a styrene resin expanded particle molded product, the expansion ratio thereof is preferably 30 to 80 times, and more preferably 40 to 70 times. Within the above range, the cushioning property and the cushioning property are excellent, and also the compression resistance and the shape retaining property are excellent, and the product is excellent as a collective packaging container for loading. In particular, in the case of a polystyrene-based resin expanded particle molded body having a weight ratio of 50 to 70 times, the bending strength is about 20 to 40 N/cm ² , and the compression strength (10% strain compression strength) is 10 to 30 N/cm ^2. Therefore, even if the collective packaging containers are stacked in about 20 stages, it is easy to obtain a container having sufficient strength and a size suitable for transportation on a pallet.
