Abstract

(57) [Abstract] [PROBLEMS] To obtain a fruit tray that can be used without a burying plate because sufficient cushioning property can be obtained in the step-down portion without a flap formed in the central portion of a cardboard box. SOLUTION: In a tray 2 in which a large number of recesses 1 are formed by molding a sheet material, ribs 3 which are convex outward are radially formed on a wall surface of the recesses 1, and a central portion 4 of a bottom wall of the recesses 1 is formed. No ribs are provided so that a space 10 that remains even when the fruit is stored is formed between the bottom surface 4a of the central portion of the bottom wall and the tray mounting surface 6. Alternatively, the step-down part 13 of the cardboard box 11
The buffer convex portion 9 is formed at the bottom of the concave portion 1 at a position corresponding to, so that the void 10 is formed between the bottom wall 9a of the buffer convex portion 9 and the fruit even when the fruit is accommodated.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fruit tray used when distributing apples, pears, peaches, etc. from their production areas to retail stores.

[0002]

[Prior art]

 Conventionally, many fruit trays have been proposed in which a large number of recesses are formed by molding a synthetic resin sheet such as polyethylene or polystyrene. There is also known a structure in which ribs are radially formed on the wall surface of the recess for the purpose of retaining the recess.

[0003]

[Problems to be solved by the device]

 In this type of fruit tray, it is important that the fruit stored in the recess is not shocked or damaged. By the way, when the fruits are distributed using the fruit tray, the tray containing the fruits is put in the cardboard box 11, but the bottom of the cardboard box 11 is not flat, and the central part is lowered in the gap of the flap 12. And the step-down portion 13 due to the step on the flap edge appears. Even such a small step may adversely affect the fruit, and the step-down part 13 is inferior in cushioning property because the corrugated cardboard paper is one layer. Therefore, at present, a corrugated board or a padding plate 14 such as a cushioning net is laid on the bottom of the corrugated box, and a fruit tray is placed on it so that the step on the flap edge does not impact the fruit. Then, the buffering property of the step-down portion 13 is improved. Therefore, there is a demand for a fruit tray having a cushioning function that can be directly placed without using a corrugated board or a filling plate such as a cushioning net.

[0004]

[Means for Solving the Problems]

 In the fruit tray of the present invention, a plurality of outwardly protruding ribs are formed on the wall surface of the recessed portion toward the center of the bottom wall, and the center portion of the bottom wall has no ribs and the bottom surface of the bottom portion of the center portion of the bottom wall and the tray mounting surface are formed. A gap is formed between the bottom of the rib and the bottom of the rib when the fruit is stored in the recess. It is the height. In the invention of claim 2, the lower ends of the adjacent ribs are brought into contact with each other, and the lower ends of the plurality of ribs jointly form an annular wall. According to the invention of claim 3, only the concave portion corresponding to the stepped-down portion of the cardboard box has the configuration of the concave portion according to claim 1 or 2. According to the invention of claim 4, when the tray is stored in the cardboard box, a buffer convex portion is formed at the bottom of the concave portion corresponding to the step-down portion of the central portion of the bottom surface of the cardboard box, and when the fruit is stored in the concave portion. A space is formed between the lower surface of the fruit and the upper surface of the bump, so that the fruit is held at the same height as the part other than the step-down part.

[0005]

[Action]

 In the inventions of claims 1, 2 and 3, the rib formed on the wall surface functions as a reinforcing rib for preventing the vertical deformation of the recess. The height of the ribs is set so that a gap can remain between the lower surface of the central portion of the bottom wall of the recessed portion and the mounting surface of the fruit tray even when storing the fruit. The center of the bottom wall does not come into contact with the fruit tray mounting surface. Therefore, since the stored fruits are not affected by the step difference on the fruit tray mounting surface, it is not necessary to use a corrugated cardboard plate or a buffer net for cushioning, and the above-mentioned conventional problems are solved.

In the invention of claim 4, since the buffer convex portion is provided in the portion corresponding to the step-down portion of the cardboard box, the buffer convex portion has the function of the conventional embedding plate. As a result, the fruits stored in the recesses with cushioning protrusions and the fruits stored in the other recesses are held at the same height, and the fruits are not affected by the step, and the corrugated cardboard paper is used. Even with a single layer, a sufficient buffering effect can be obtained.

[First Embodiment of the Invention]

A fruit tray 2 is formed by forming a large number of hemispherical concave portions 1 on a planar rectangular synthetic resin sheet. A plurality of ribs 3 are formed on the wall surface of the concave portion 1 so as to project outward from the concave portion 1 toward the center portion 4 of the bottom wall. The lower ends of the plurality of ribs 3 are in contact with each other, the lower ends of the plurality of ribs 3 cooperate to form an annular wall 5, and the lower surface 4a of the central portion 4 of the bottom wall located inside the annular wall 5 is a rib. It is located above the lower surface of the annular wall 5 constituted by the lower end portion of 3.

That is, a space 7 is formed between the lower surface 4 a of the central portion 4 of the bottom wall and the mounting surface 6 of the fruit tray 2. The protruding height of the annular wall 5 is such that, even when the fruit 8 is stored in the recessed portion 1, there is a gap between the lower surface 4a of the central portion 4 of the bottom wall and the mounting surface 6 of the fruit tray 2. Is the height that can remain. The specific height of the protrusion is determined in consideration of the weight of the fruits to be stored, the material of the synthetic resin sheet, the thickness, and the like. The upper end position of the rib 3 may be appropriately determined based on the necessity of reinforcing the concave portion 1 in the vertical direction, and there is no particular limitation. Further, the protrusion size of the ribs 3 is sufficient if the protrusion amount of the lower end portion satisfies the condition that the above-mentioned void remains, and the protrusion amount other than the lower end portion can be appropriately determined.

When the fruit 8 is stored in the recessed portion 1 of the fruit tray 2 shown above, the fruit 8 is supported by the annular wall 5 portion formed at the lower end of the rib 3. At this time, the annular wall 5 is crushed by the weight of the fruit 8, but since the annular wall 5 has a sufficient protruding height, it is between the lower surface 4a of the central portion 4 of the bottom wall and the tray mounting surface 6. The void 7 remains. Therefore, the gap 7 is interposed between the lower end portion of the fruit 8 and the tray mounting surface 6 as a buffer portion.

In the above embodiment, since the lower ends of the plurality of ribs are in contact with each other to form the annular wall, the holding strength at the lower ends of the ribs is large and the ribs are prevented from being crushed by the weight of the fruit as much as possible. However, the annular wall does not have to be formed as long as the void is maintained below the central portion of the bottom wall. In addition, if only the concave portion corresponding to the step-down portion 13 of the cardboard box 11 has the configuration of the concave portion shown in the above embodiment, the embodiment of the invention of claim 3 is obtained.

Second Embodiment of the Invention

FIG. 5 shows an embodiment of the invention of claim 4. The fruit tray on which a large number of recesses 1 are formed has a planar shape and size suitable for the cardboard box 11. Here, as described above, a step-down portion 13 not covered with the flap 12 is formed in the central portion of the cardboard box 11. A buffer projection 9 is provided at the bottom of the recessed portion 1 (including the recessed portion extending over the flap 12 and the step-down portion 13) corresponding to the stepped-down portion 13. The height of the buffer convex portion 9 is equal to or more than the depth of the step-down portion 13, that is, the thickness of the flap 12, preferably slightly higher. The fruit 8 is supported by the peripheral wall of the cushioning convex portion 9, and a space 10 is formed between the lower surface of the fruit 8 and the bottom wall 9a of the buffering convex portion 9. As a result, even in the cardboard box 11 having the step-down portion, all the recessed fruits 8 are supported at almost the same height, and the step-down portion 13 does not give an impact to the fruit.

[0012]

[Effect of the invention]

 According to the inventions of claims 1 and 2, the ribs having a convex shape are formed on the concave portion and the central portion of the bottom wall has no rib to form the fruit tray, so that the fruit stored in the concave portion is formed. The weight is supported on the lower ends of the ribs. Since the void formed below the lower surface of the central part of the bottom wall can remain even when the fruit is stored, there is a gap between the fruit stored in the recess and the fruit tray mounting surface. To do. According to the invention of claim 3, since the bottom wall of the recessed portion corresponding to the stepped-down portion of the corrugated cardboard box is supported by the ribs, there is no flap and there is a cushioning property in the stepped-down portion where the corrugated paperboard is one layer. By improving the rib height, the fruit can be supported at the same height as the flapped portion. In the invention of claim 4, since the buffer convex portion is provided in the concave portion corresponding to the step-down portion of the corrugated cardboard box, a gap is obtained between the bottom wall of the buffer convex portion and the fruit. Similar to the plan, the cushioning property at the step-down portion of the cardboard box is improved, and at the same time, the fruit can be supported even at the step-down portion at the same height as the portion with the flap. Therefore, there is no risk of bumps on the bottom of the corrugated cardboard for storing fruit trays, such as unevenness on the bottom of the storage corrugated ball, impacting the fruit, and the buffering performance of the step-down part, which is inferior in buffering property, is improved. Therefore, the fruit tray can be placed and stored directly on the bottom of the cardboard box without laying a buffer cardboard plate or buffer net.
