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, a fruit packaging tray is configured by forming a large number of recesses in a sheet made of expanded polystyrene resin, and the recesses are formed of apples, pears, or the like. It has a substantially hemispherical shape suitable for fruits, and the tray surface is formed in a perfect circle shape.

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. The maximum dimensions of the outer shape are defined so as to obtain the above. On the other hand, fruits such as apples and pears are sorted into several grades having almost the same size according to their light weight or size. Therefore, since the outer dimensions of the tray are determined as described above, the number of fruits that can be stored is defined by the grade, and the recessed portion having a size corresponding to the size of the fruits to be stored is described above. It is formed by the number.

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, there are a number of recesses suitable for each grade, for example, for 25, 2
It is necessary to prepare a large number of types of trays that are finely classified for 6 pieces, 27 pieces, etc., and there is a problem that the productivity of the trays is poor.

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, if the concave portions are arranged irregularly, not only is the fruit storage balance unbalanced, but when the fruits are stored in a cardboard box, they are 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 in that workability is poor because the trays must be stacked while paying attention to the directionality of the trays when they are packed in a box.

This invention has been made in view of the above problems,
It can store 26 fruits efficiently and in a well-balanced manner, has good tray productivity, and has excellent workability in packaging. In addition, even if the diameter of the fruits varies, 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 being damaged.

<Means for Solving the Problems> In order to achieve the above object, the fruit packaging tray of the present invention is entirely made of an elastic synthetic resin sheet such as a foamed sheet and has a rectangular shape in which 26 fruits are accommodated. Shaped tray with 6 oval recesses (1) (2) (3) (4) (5) (6) and (7) (8) (9) (10) (11) (12) ) Row of depressions (l ₁ ) (l ₂ )

<Operation> According to the fruit packaging tray having the above-described configuration, the entire tray is made of a synthetic resin sheet having elasticity such as a foamed sheet, and the concave portion for accommodating the fruits is an elliptical concave portion (1) to (2).
Since it is formed in 6), when you put fruit, it is formed in the oval recesses (1) to (26), so when you put fruit,
The minor axis of the oval recesses (1) to (26) expands according to the size of the fruit, so if the fruit has a larger diameter than the corresponding fruit, the minor axis side of the ellipse will expand greatly. This fruit can be accommodated, and conversely, in the case of a fruit having a small diameter, the minor axis of the ellipse is slightly expanded to accommodate the fruit, and the ball rotation can be prevented.

Also, six oval recesses (1) (2) (3) (4) (5) (6) and (7)

(13) (14) (15) (16) is arranged in the direction parallel to the short sides (S) (S '), and the elliptical recesses (21) (22) (23) By arranging the directions of the long diameters of (24), (25), and (26) in the direction parallel to the long sides (L) and (L '), the concave portions (1) to (26) are formed in an elliptical shape. Despite that, the length along the long side (L) (L ') and the short side (S) (S') is not longer than that of a circular recess. . Therefore, 26 oval recesses (1) to (26) can be arranged within the specified size.

Furthermore, since the respective elliptical recesses are symmetrically arranged so that the long sides (L) and (L ') are in the same position with the long sides (L) (L') reversed, when stacking the trays vertically, Only by matching the outer shapes, the elliptical recesses provided in the upper and lower trays can be overlapped with each other no matter which direction they are stacked.

<Embodiment> Next, an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a fruit packaging tray according to the present invention.

This fruit packaging tray is made of a material that can be slightly elastically deformed,
For example, it is made of expanded polystyrene sheet and has a rectangular outer shape. When 26 fruits are stored,
26 oval recesses that expand in diameter according to the size of the fruit
It has (1) to (26). The arrangement configuration of the 26 oval recesses (1) to (26) is as follows.

6 oval recesses (1) (2) (3) (4) (5) (6), (7) (8) (9)

(20) is formed along the short sides (S) (S '). Then, between the concave row (l ₁ ) and the central row (l ₃ ), the oval concaves (2) (3), (3) (4), (4) (5) and the concaves are formed. column (l ₃₎ with an elliptical recess respectively (21) (22) (23) is formed between the, be between the central column (l ₃₎ and the recess row (l ₂₎ The elliptical recesses (24), (25) and (26) are formed between the elliptical recesses (8) (9), (9) (10) and (10) (11). Also, the elliptical recesses (22) and (25) are arranged slightly closer to the longer sides (L) (L ') than the adjacent elliptical recesses (21) (23) and (24) (26). ing.

In addition, the elliptical recesses (1) (6) at both ends of the recessed row (l ₁ ) and the elliptical recesses (7) (12) at both ends of the recessed row (l ₂ ) are the ends of the long diameter. Are arranged so as to be inclined toward the long sides (L) (L ′) and the short sides (S) (S ′). Then, the elliptical recess (2) (3) (17) (10) (11) (12) (20), the major axis is parallel to the direction of the major axis of the elliptical recess (1) (12). It is arranged. The major axis of the elliptical recesses (4), (5), (18), (8), (9) and (19) is arranged parallel to the major axis direction of the elliptical recesses (6) (7).

Also, the elliptical recess (21) (22) (23) and (24) (25) (26),
The major axis of each is parallel to the major side (L) (L '), and the elliptical recesses (13) (14) (15) (16) have their major axis on the minor side (S).
It is parallel to (S ').

Furthermore, each of the elliptical recesses (1) to (26) has a long side (L).
They are arranged symmetrically so that they are in the same position as each other when (L ′) is reversed.

As shown in FIG. 2, each of the elliptical recesses (1) to (26) is formed in a substantially bowl shape so as to accommodate fruits, and the bottom portion (30) is formed in a flat surface. ing. In addition, ribs (31) protruding inward are provided on the side surfaces of the oval recesses (1) to (26), so that the impact on the stored fruit can be mitigated and the large-sized fruit can be absorbed. When was housed,
It is supposed to grow. In addition, each oval recess (1)
A concave portion (32) is provided adjacent to (26) to (26). The concave portion (32) improves the strength in the twisting direction of the tray.

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 mixture of the styrene and another polymer (foamed by foaming a composite resin A sheet is preferably used, for example, styrene-ethylene copolymer, styrene-
Propylene copolymer, styrene-styrene-butadiene copolymer styrene-olefin copolymer, and polystyrene,
A foamed sheet of a mixed resin with a polyolefin resin such as polyethylene, polypropylene or polybutadiene has excellent flexibility and elasticity, and is therefore 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 polypinyl 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 above-exemplified synthetic resin sheet, for example, by using a conventionally known forming method such as press forming or vacuum forming using a mold having a predetermined shape, the shape shown in the figure is obtained. A fruit packaging tray can be easily obtained. Also, for other materials as well,
The material can be manufactured by a conventionally known method.

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

For example, the elliptical recesses (1), (6), (7) and (12) formed at the corners have their long ends at the long side (L) (L ') and short side (S).
Although it is formed in the direction close to (S '), it may be formed by turning one side of the major axis toward the corner, which is the direction rotated by about 90 degrees from this direction, and it may be formed in the center of the tray. The elliptical recesses (22) and (25) that are formed are slightly longer sides (L) than the adjacent elliptical recesses (21) (22) and (24) (26).
(L ′), but adjacent elliptical recesses
Together with (21) (22) and (24) (26), they may be formed in a line in the direction parallel to the long sides (L) (L '), and other various designs are possible without changing the gist of the present invention. You can make changes.

The size of each of the oval recesses (1) to (26) is not particularly limited in the present invention, and the major axis depends on the diameter of the fruit of the corresponding grade, the maximum diameter of the fruit that can be stored, the range of the minimum diameter, etc. It is possible to select various dimensions of each part, such as the length of the minor axis. To give an example, the ellipse of the oval concave part has a major axis dimension (1/2 of major axis) of 52.5 mm and a minor axis dimension (1/2 of minor axis).
An ellipse or the like formed to 49.5 mm can be used.

<Effect of the Invention> As described above, according to the fruit packaging tray of the present invention,
Since it is configured as described above, 26 elliptical recesses (1) to (26) are efficiently provided on the tray having the specified size, even though each recess is formed in an elliptical shape. Moreover, it can be formed in good balance.

Further, the concave portion is formed in an elliptical shape, and the minor axis is expanded in accordance with the fruit size, so that the flexibility with respect to the size of the fruit is high, and even if the fruit with the same grade and a variation in diameter is accommodated,
All the fruits can be accommodated without breaking the tray, and even a small fruit does not cause a girth or the like in the oval recess, so there is no risk of scratches. 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 27 can be accommodated. On the contrary, even if a small-sized fruit selected for 29 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 that one type of tray can be used not only for 26 but also for 25 and 27. Therefore, the productivity of the tray can be improved.

Furthermore, since the elliptical recesses are symmetrically arranged so that the long sides (L) and (L ') are in the same position with the long sides (L) (L') reversed, it is not necessary to consider the orientation of the tray. Even if stacked, the upper fruit will always be stacked directly on the lower fruit, and the weight of the fruit is applied to the center of the whole fruit, eliminating the risk of scratching the fruit. With
It is possible to improve workability in packaging fruits in boxes.
