おいては、上記のトレーに収納した状態で、段ボール箱
等に積み重ね収容するのが普通であり、一般には１箱
（２段重ね）の基準重量は約１０ｋｇ以上とされてい
る。When fruits such as peaches, pears, and apples are shipped, they are usually stored in the above trays in a corrugated cardboard box or the like, and generally one box (two layers). The standard weight is about 10 kg or more.

てしまうことになる。By the way, peaches, pears, apples and the like have different shapes and densities, and even in the case of the same apple, the flat shape "Tsugaru", the relatively round shape "Fuji", and the substantially inverted triangular shape " Since the shape is different from that of Wanglin etc. and the diameter size at the same weight is different, if the same kind of tray is used for different kinds of fruit, the variation in quantity will inevitably increase, and it will be 10 kg or more per box. It will be greatly deviated from the standard weight.

る。For example, FIG. 8 shows the relationship between the weight and the diameter of each peach, pear, and apple (a diameter obtained by measuring the major axis and the minor axis and adding them to divide into two equal parts). FIG. 8 shows the average diameter for each weight obtained by measuring a large number (hundreds) of fruits. As is clear from FIG. 8, the diameters of peach, pear, and apple even with the same weight have a diameter difference of 4 to 8 mm, although there are some differences depending on the weight.

のトレーが必要とされていた。However, in the case of the above-mentioned single-layer tray as well as the case of a multi-layer tray using a flexible material on the inside, the above-mentioned difference in diameter cannot be absorbed, and therefore, it is slightly different for each kind of fruit. It was unavoidable to use special trays with different sizes, and many types of trays were required.

そのトレーの管理等がきわめて面倒であり、作業効率上
も望ましいものではない。Especially in recent years, it has become difficult to manage various types of trays due to lack of manpower in the sorting fields such as agricultural cooperatives. The introduction of an automatic fruit selection system controlled by (which judges the fruit weight, shape, sugar content, ripeness, color tone, etc.) has started. In this case, using different trays for each fruit
The management of the tray is extremely troublesome, and it is not desirable in terms of work efficiency.
【０００９】そのため、この自動選果システムの実施に

着目してなしたものである。In the present invention, as a result of various research and devising to meet the above-mentioned demand, the diameter difference between peach, pear and apple is 4 to 4.
If it is about 8 mm, and if this difference in diameter can be absorbed by the shape of the storage recess and the characteristics of the material, it is possible to store these different types of fruits in the same fruit tray without causing variations in quantity. This is done by focusing on the fact that the same tray can be used for different kinds of fruits.

The storage recess is formed of layers, and the inner surface of the storage recess is characterized in that the upper portion of the side wall surface is formed as a curved surface portion, and the lower portion following the side wall surface is formed as a tapered surface portion that is linear in vertical cross section and continuous to the bottom portion. The curved surface portion has a recess depth of approximately 2
A range of about / 3 is preferable.

樹脂も、座屈し易くて弾力性があり使用可能である。In the above description, the inner flexible foam layer with which the stored fruits come into contact is a soft material that is softer than the fruits and does not damage the fruits and has shock absorption, such as a cross-linked polyethylene foam. Polyolefin foams such as crosslinked or non-crosslinked polypropylene foams can be used. In the case of this polyolefin resin foam, the crosslinked type is preferable because the thermoformability from the sheet is good. In addition to the above, other relatively soft resin foams such as polyurethane resin foams can be used. Further, a highly expanded polystyrene resin can be used because it easily buckles and has elasticity.

寸法内に必要個数の収納凹部を形成できなくなる。The thickness of this foam layer is 1.5 because it has the purpose of absorbing the above-mentioned diameter difference between peach, pear and apple.
It is about 6.0 mm, preferably 2.0 to 4.5 mm.
That is, if the thickness is smaller than the above value, the effect of absorbing the difference in diameter cannot be expected, and the cushioning property becomes poor. Further, if the thickness is larger than the above, it becomes impossible to form a required number of storage recesses within a certain plane dimension corresponding to a cardboard box.

3 , preferably 0.027 to 0.045 g / cm 3 ,
A relatively high foam is used. That is, when the density is higher than the above value, the effect of absorbing the diameter difference becomes small and the buffering property becomes poor. On the other hand, when the density is lower than the above-mentioned density, the strength is weakened and breakage easily occurs.
【００１７】なお、発泡層としては、最大圧縮の変形量

れる。Regarding the outer resin layer laminated with the foam layer, a relatively hard synthetic resin material such as polystyrene resin is used in view of preventing movement of fruits during transportation, pressure resistance and shape retention. A foamed sheet or non-foamed sheet of resin, a non-foamed sheet of polyvinyl chloride resin, or a comparatively low-foaming sheet of polypropylene resin or a non-foamed sheet is preferably used.

収容した場合の安定性も劣る。The thickness of this resin layer varies depending on the material, but is 0.5 to 3.0 mm, preferably 0.5 to 2.5.
About mm is suitable. That is, if the thickness is too small, shape retention strength and pressure resistance cannot be obtained, which is not preferable in handling in an automatic fruit sorting field, and the stability when stacked and stored in a corrugated box is poor.

At this time, the fruit with a relatively large diameter is fitted into the curved surface part of the upper part of the inner surface shape of the storage recess to be held in the housed state, and the fruit with a slightly smaller part or the smaller part has a longitudinal section. It is fitted into the linear lower tapered surface and is held in the housed state.

The diameter of the opening of the recess is easily increased. That is, when the entire circumference of the opening of the storage recess is continuous without being dropped, the diameter cannot be expanded more than the compression deformation of the inner layer, but in the case of the present invention, the column portion easily deforms as described above. Therefore, the diameter of the opening portion is easily expanded. Therefore, it becomes possible to store fruits having a larger diameter difference.
