Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a fruit packaging tray, and more specifically, it protects a substantially spherical fruit such as an apple or a pear from impact and safely transports or stores it. The present invention relates to a fruit packaging tray.

<Problems to be Solved by Conventional Techniques and Inventions> Generally, the fruit packaging tray is configured by forming a large number of recesses in a sheet made of expanded polystyrene resin or the like, and the recesses are apples or pears. It has a substantially hemispherical shape suitable for fruits and the like, and has a perfect circular shape on the tray surface.

The tray is used for transportation, storage, etc., in which a plurality of fruits are stored in a recessed portion and stacked in a cardboard box, and are stored in a cardboard box conforming to a standard such as AS standard. Its maximum size is defined for obtaining. On the other hand, the fruits such as apples and pears are sorted into several grades having almost the same size according to their lightness or weight and size. Therefore, since the outer diameter of the tray is determined as described above, the number of fruits that can be stored is defined by the above grade, and the size of the tray depends on the size of the fruits to be stored. The recessed portions are formed by the number described above.

However, since the perfect circular recess has little flexibility with respect to the size of the fruit, it cannot accommodate fruits of a grade other than the corresponding grade, that is, a fruit other than the prescribed size. Therefore, conventionally, the number of recesses suitable for each grade is the same, for example, for 19
There has been a problem that the productivity of the trays is poor because it is necessary to prepare a large number of types of trays that are finely classified for 0 pieces, 21 pieces, and the like.

In recent years, weight selection has become the main method for selecting fruits, and the diameters of the fruits are not constant even if they are of the same grade. Therefore, in the above tray, for example, a fruit having a diameter larger than that of the recess is difficult to store in the recess and the tray may be damaged if the tray is forcibly inserted. In the middle or the like, there is a risk of rotation (so-called ball rotation) within the recess, collision with the inner wall surface of the recess, or jumping out of the recess, resulting in damage.

Further, in the conventional tray, if the recesses are arranged regularly, many recesses cannot be formed within the specified size, and the efficiency of storing fruits is deteriorated, so that more fruits can be stored. In order to do so, a device in which the above recesses are arranged irregularly has been devised (see Japanese Utility Model Publication No. 57-6392).

However, the one with irregular recesses is not only unbalanced for storing fruits, but when it is stored in a cardboard box, it is rotated 180 ° about the center of the tray as a fulcrum and stacked in the opposite direction. Fruits stored in the tray of are not neatly aligned with each other and are under heavy load,
Easy to hurt during transportation. Therefore, in the above tray, there is a problem that the workability is poor because the tray must be packed with attention to the directionality of the tray.

This invention has been made in view of the above problems,
Efficient and well-balanced storage of 20 fruits, good tray productivity, and excellent boxing workability, and even if there are variations in the diameter of the fruits, the tray may be damaged or the fruits may be damaged. The object is to provide a fruit packaging tray that does not have the risk of

The major diameters of the elliptical recesses (6) to (10) and (11) to (15) of (l ₃ ) are arranged parallel to the short sides (S) and (S '), and there are two rows on both sides. Depression row (l ₁ ) (l ₄ ) oval depression (1) ~
Of (5), (16) to (20), an elliptical recess located at the end
(1) (5) (16) (20) are arranged so that the ends of the major axis are inclined so that they are close to the long sides (L) (L ') and the short sides (S) (S'). And the remaining oval recesses (2)-(4), (17)-
The long diameter of (19) is arranged parallel to the long sides (L) (L '). Furthermore, the elliptical recesses (1) to (20) are long sides (L).
(L ′) is reversed, symmetrically arranged so that they are in the same position when rotated 180 degrees, and two or more trays have their long sides (L) and (L ′) reversed. Even when stacked, the upper and lower elliptical recesses (1) to (20) overlap each other.

As shown in FIG. 2, each of the elliptical recesses (1) to (20) is formed in a substantially bowl shape so that fruits can be stored therein.
The bottom portion (30) is formed to be flat so that it is not easily deformed. Also, on the side surfaces of the oval recesses (1) to (20),
The ribs (31) projecting inward are provided so that the impact on the stored fruit can be mitigated and this portion is extended when the large-sized fruit is stored. Further, a concave portion (32) is provided in a portion adjacent to each of the elliptical concave portions (1) to (20). The recess (32) improves the strength of the tray in the twisting direction.

As the synthetic resin sheet constituting the tray, in addition to the expanded polystyrene sheet, a copolymer containing 50% by weight or more of styrene, or a foamed sheet obtained by foaming a mixed resin of the styrene and another polymer. It is preferably used. For example, styrene-ethylene copolymer, styrene-
A propylene copolymer, a styrene-olefin copolymer such as a styrene-butadiene copolymer, or a foamed sheet of a mixed resin of polystyrene and a polyolefin resin such as polyethylene, polypropylene or polybutadiene,
Since it is excellent in flexibility and elasticity, it is particularly suitable as a material for the fruit packaging tray of the present invention. In addition to the above materials, a thermoplastic resin sheet such as polyvinyl chloride can also be used as a material for the fruit packaging tray of the present invention.

To form a fruit packaging tray from the materials exemplified above,
For example, by using a conventionally known forming method such as press forming or vacuum forming using a mold having a predetermined shape, the fruit packaging tray having the shape shown in the drawing can be easily obtained.

The fruit packaging tray of the present invention is not limited to the above embodiment.

For example, as shown in FIG. 3, the recess middle columns two columns (l ₂₎ elliptical recess in _{(l 3) (6) ~} (10), (11) ~
The major axis of (15) may be arranged to be inclined with respect to both sides, and the elliptical recesses (2) of the recess row (l ₁ ) (l ₄ ) on both sides may be arranged.
The major axes of (4) and (17) to (19) may be arranged to be inclined with respect to both sides. In addition, the elliptical recesses (1) (5) (16) (20) placed at the corners have the long side ends with the long sides.
(L) (L ') and short sides (S) (S') are formed in a direction close to each other, but a direction rotated by approximately 90 degrees from this direction, that is, one end of the major axis is directed to the corner It may have been done. In short, each of the elliptical recesses has a long side
It may be arranged so that the lengths in the directions of (L) (L ') and the short sides (S) (S') do not become large, and various design changes can be made without changing the gist of the invention. .

The dimensions of each of the elliptical recesses (1) to (20) are not particularly limited in the present invention, and the major axis, the diameter of the fruit of the corresponding grade, the maximum diameter of the fruit to be stored, the range of the minimum diameter, etc. Various dimensions such as the length of the minor axis can be selected. For example, the elliptical recess has a major axis dimension (1 / the major axis).
It is possible to adopt an ellipse in which 2) is 40.75 mm and the minor axis dimension (1/2 of the minor axis) is 39.5 mm.

<Effect of the Invention> As described above, according to the fruit packaging tray of the present invention,
Since the arrangement and the direction of the major axis of the elliptical recesses are configured as described above, even though each of the recesses is formed in an elliptical shape, 20 elliptic recesses ( 1)
(20) can be formed efficiently and in good balance.

Further, this tray is formed entirely from a synthetic resin sheet having elasticity such as a foamed sheet, and the concave portions for accommodating fruits are formed in the elliptical concave portions (1) to (20). It is highly versatile and can accommodate all fruits of the same grade and with different diameters without breaking the tray, and a little smaller fruit in the oval recess. There is no risk of scratching the fruit as it does not cause ball rolling.

Moreover, even when a large fruit having a diameter one rank higher is put in, the tray is deformed and expanded correspondingly without being damaged, so that the large fruit selected for 19 can be accommodated. On the contrary, even if a small-sized fruit selected for 21 pieces is accommodated, it is possible to eliminate the risk that the fruit will be rotated in the recess and scratched. Therefore, in addition to the prescribed grade of fruits, it is possible to store fruits sorted into upper and lower grades, so one type of tray can be used not only for 20 but also for 19 and 21 Therefore, the productivity of the tray can be improved.

Furthermore, each of the elliptical recesses (1) to (20) has a long side (L).
Since (L ′) is reversed, they are symmetrically arranged so that they are in the same position, so even if they are stacked without considering the directionality of the tray, be sure to place them directly above the fruit below. Since the fruits above will be stacked and the weight of the fruits will be applied to the center of the whole fruits, it is possible to eliminate the risk of scratching the fruits and improve the workability in packaging the fruits. it can.
