Description

TECHNICAL FIELD The present invention relates to a packaging container used for storing and transporting heavy spherical fruit vegetables such as watermelon.

2. Description of the Related Art Conventionally, harvested fruit vegetables and fruits have been widely stored in a predetermined storage container for a certain period of time, for example, in order to adjust shipping time and ripen. When storing and transporting such fruit vegetables and fruits, it is common to use a cushioning material made of foamed resin for fruits such as pears and peaches, which have soft and easily damaged skins (see, for example, Patent Document 1). ).

On the other hand, fruit vegetables such as watermelon, which have a relatively hard skin and can be stored at room temperature, are generally stored in simple containers such as cardboard boxes and plastic containers, and even if cushioning materials are used. For example, a simple mesh-like material is used.

In recent years, however, Japanese fruit vegetables and fruits are increasingly being exported to other countries, and it sometimes takes a long time to transport them. Therefore, for air transportation, for example, even if the container is dropped, the contents are required to have impact resistance so that the contents are not damaged, and cold insulation is required to transport the fruit vegetables in a chilled state. In particular, heavy spherical fruit vegetables such as watermelon may not be able to obtain sufficient impact resistance even with the cushioning material described in Patent Document 1 above.

An object of the present invention is to solve the above problems, and to provide a packaging container that can be used for storing and transporting heavy spherical fruit vegetables such as watermelon, and that has sufficient shock resistance and cold insulation. aim.

In order to achieve the above object, the present invention provides a packaging container made of foamed resin, comprising a pair of box-shaped container bodies having an opening on one side, wherein the pair of container bodies have the same shape as each other; are turned upside down and fitted together to form a storage portion for storing a substantially spherical fruit vegetable, and the container body includes a substantially rectangular bottom plate and four walls erected from each side of the bottom plate. a plate and a plurality of support ribs that are provided so as to straddle the bottom plate and the wall plate and partition the housing portion, wherein the support ribs are located substantially in the center of the wall plate and between the wall plates in a plan view. The center portion of the support rib is formed as a curved concave portion, and the fruit vegetables are spaced from the bottom plate by the concave portion. It is characterized in that it is held in a position where the

In the above-described packaging container, the bottom plate has a cylindrical portion protruding toward the center of the accommodating portion at substantially the center thereof, and the cylindrical portion does not come into contact with the fruit vegetables held by the support ribs. It is preferably configured to be tall.

In the above-described packaging container, the wall plate includes a peripheral surface forming the opening, an outer peripheral convex portion provided outside the peripheral surface and being higher than the peripheral surface, and provided outside the peripheral surface. and an outer edge recess that is stepwise lower than the peripheral surface, and the outer edge protrusion and the outer edge recess are provided at a pair of opposing corners, respectively, and are fitted to each other to form a pair of the Preferably, the container bodies are connected.

According to the present invention, the accommodating portion is configured by the elastic foamed resin container body, and the fruits and vegetables are held in a floating state by the concave portions of the supporting ribs, so that a large amount of food can be seen from the outside of the packaging container. Fruit vegetables can be safely preserved even if force is applied. In particular, even if the packaging container containing heavy spherical fruit vegetables such as watermelon is dropped, the supporting ribs are destroyed, thereby reducing the impact on the fruit vegetables and suppressing damage to the fruit vegetables. It is possible to obtain the impact durability that can be obtained. In addition, since the foamed resin that constitutes the container body has high heat retention, it is possible to obtain high cold retention for transporting fruit vegetables in a chilled state. Therefore, it is possible to directly keep fruits and vegetables cold by storing ice packs and ice in these compartments.

(a) is a plan view of the container body; (b) is a bottom view; (c) is a front view; (d) is a left side view; (a) is a front view of the packaging container in use, and (b) is a front cross-sectional view corresponding to (a).

A packaging container according to one embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. As shown in FIG. 1, the packaging container 1 includes a pair of container bodies 2 made of foamed resin. The container main body 2 is a box-shaped member having an opening 20 on one surface, and has a substantially square rectangular shape in plan view. In the packaging container 1, one of a pair of container bodies 2 having the same shape is turned upside down and fitted to each other as shown in the figure, thereby forming a storage portion 10 for storing a substantially spherical fruit vegetable S.

The container body 2 is a molded body of foamed synthetic resin, and is integrally molded by, for example, filling foaming particles of a thermoplastic resin into a mold and heating to foam them. The thermoplastic resin may be, for example, a styrene resin, or a composite resin obtained by mixing a styrene resin with another resin such as an olefin resin.

As shown in FIGS. 2(a), 2(b) and 3(a) to 3(e), the container body 2 includes a rectangular bottom plate 21 and four wall plates 22 erected from each side of the bottom plate 21. , and an opening 20 is formed by the peripheral edge of the upper end side of the wall plate 22 (the side opposite to the bottom plate 21). The outer peripheral surfaces of the bottom plate 21 and the wall plate 22 are smooth planes so that a label or the like can be easily attached during transportation. Four corners of the container body 2 are chamfered so as to be rounded. The outer peripheral surface of the bottom plate 21 may be provided with a non-slip structure such as unevenness (not shown) so that the plurality of packaging containers 1 are not easily displaced when loaded.

The wall plate 22 has a peripheral edge surface 23 which is an upper end surface and forms the opening 20, an outer edge convex portion 24 which is provided outside the peripheral edge surface 23 and is higher than the peripheral edge surface 23, and the outside of the peripheral edge surface 23. and an outer edge recessed portion 25 provided in the outer edge recessed portion 25 that is stepwise lower than the peripheral edge surface 23 . The outer edge convex portion 24 and the outer edge concave portion 25 are provided at a pair of opposing corners, respectively, and are fitted together to connect the pair of container bodies 2 (see FIG. 1).

The upper end surfaces of the outer edge convex portion 24 and the outer edge concave portion 25 are connected by an inclined surface 26 . Therefore, when one of the pair of container bodies 2 is turned upside down with respect to the other and fitted together, the outer edge protrusion 24 of one container body 2 and the outer edge recess 25 of the other container body 2 come into contact with each other. . When trying to fit them together, since the inclined surfaces 26 slide against each other, one outer edge protrusion 24 is guided by the other outer edge recess 25, and the positional relationship between the upper and lower container bodies 2 is slightly shifted. They can be easily mated even if they are

The container main body 2 includes a plurality of support ribs 3 that are provided so as to straddle the bottom plate 21 and the wall plate 22 and partition the housing section 10 . The support ribs 3 project from substantially the center of each wall plate 22 toward the center of the housing portion 10 in plan view, and include short ribs 3a perpendicular to the wall plate 22 and corner portions of the wall plate 22 in plan view. A long rib 3b protrudes from the center of the housing portion 10 and is inclined at 45° from the wall plate 22 (see FIG. 3A). A central portion of the support rib 3 is formed as a curved concave portion 31 . The concave portion 31 includes an arc that forms a circle (see the dashed-dotted line circle in FIG. 3(e)) having a stop on the peripheral surface 23 line in a front cross-sectional view. is held at a position spaced from the bottom plate 21 by a predetermined distance.

Also, the bottom plate 21 has a cylindrical portion 4 protruding toward the center of the housing portion 10 at substantially the center thereof. The cylindrical portion 4 is configured to have a height that does not come into contact with the fruits and vegetables held by the support ribs 3 (see FIG. 4(b) in particular).

The dimensions of the bottom plate 21 are, for example, 300 to 400 mm square, and the height of the wall plate 22 is, for example, 150 to 250 mm. The thickness of the wall plate 22 is, for example, 10-40 mm. Moreover, the thickness of the support rib 3 is, for example, 10 to 30 mm. The concave portion 31 is configured to have a height of 70 to 80 mm from the outer surface of the bottom plate 21, and the substantially spherical fruit vegetables S are held at a position spaced about 70 mm from the outer surface of the bottom plate 21. be. Further, the cylindrical portion 4 is configured to have a height of 45 to 55 mm from the outer surface of the bottom plate 21 .

According to the packaging container 1 configured as described above, since the accommodating portion 10 is constituted by the elastic foamed resin container main body 2, the container main body 2 itself functions as a cushioning material, and the container is accommodated. Fruit vegetables S can be protected. Moreover, since the fruit vegetables S are held in a floating state by the concave portions 31 of the support ribs 3, even if a large force is applied from the outside of the packaging container 1, the force does not reach the fruit vegetables S. S can be stored securely. In particular, even if the packaging container 1 containing heavy spherical fruit vegetables S such as watermelon is dropped, the support ribs 3 made of foamed resin are destroyed, thereby reducing the impact on the fruit vegetables S. , impact durability that can suppress damage to the fruit vegetables S can be obtained. Moreover, when the support ribs 3 are destroyed, the cylindrical portion 4 functions as a cushioning material to receive and hold the fruit vegetables S, so damage to the fruit vegetables S can be suppressed more reliably.

In addition, since the foamed resin forming the container body 2 has high heat retention, it is possible to obtain high cold retention for transporting the fruit vegetables S in a cooled state. In addition, since the storage part 10 is divided into a plurality of compartments by the support ribs 3, a cooling agent and ice can be stored in these compartments, and the fruit vegetables S can be directly kept cold.

In addition, since the outer edge convex portion 24 and the outer edge concave portion 25 of the pair of container bodies 2 of the packaging container 1 are mutually fitted and connected, the pair of container bodies 2 will not be easily disassembled. Even if the packaging container 1 containing the S is overturned, the fruit vegetables S can be stably contained and held.

In addition, the present invention is not limited to the above-described embodiment, as long as it is a configuration in which a storage portion is formed in a container made of foamed resin and a plurality of support ribs provided inside the storage portion hold a substantially spherical fruit vegetable. , various modifications are possible. For example, in the above-described embodiment, the configuration having eight supporting ribs 3 was shown. may increase. Further, the shape of the recessed portion 31 can be changed according to the shape of the fruit vegetable S, and it is not limited to a true spherical shape, and can correspond to, for example, an elliptical shape.
