Description

[Detailed Description of the Invention] This invention relates to a tray for packaging fruits, etc., and is intended to provide a tray that is well suited to the size, shape, etc. of the fruits, etc. to be stored.

BACKGROUND OF THE INVENTION Conventionally, synthetic resin trays having a large number of bowl-shaped storage recesses have been used as packaging bodies for transporting fruits such as apples and pears and vegetables such as tomatoes. These trays have the advantage of being able to efficiently store fruits and the like one after another in the storage recesses, as well as being able to effectively protect the stored items from impacts during transportation, and have rapidly become popular in recent years.

However, the above-mentioned trays are not compatible with the size and shape of the stored items, and even when packaging fruits of the same variety, it is necessary to use a variety of trays that are compatible with each size and shape. This is the actual situation. For this reason, molds for molding trays have diversified, and production efficiency has been reduced due to the increased variety of trays and smaller lots, contributing to higher costs, and improvements have been desired.

This invention aims to solve the above-mentioned conventional disadvantages by improving the suitability of the storage recess for the stored items. The inner circumferential wall of the recess is formed with a rib-shaped portion bulging in the vertical direction, and the rib-shaped portion is divided into right and left sides by a groove.

Next, embodiments of this invention will be described in detail below with reference to the drawings.

Reference numeral 1 shows the entire tray for packaging fruits, etc., and in the case of the figure, a tray capable of storing 12 pieces of fruits, etc. is illustrated as an example. The tray is obtained by molding a foamed sheet of thermoplastic resin such as a foamed polystyrene sheet in a predetermined manner, and a plurality of rib-like portions 11 are formed to bulge in the vertical direction on the inner circumferential wall of the storage recess 10. A kerf 12 of a predetermined width is formed in the rib-shaped portion 11 near the bulging top portion along the longitudinal direction of the rib. By forming the kerf 12, the rib-shaped portion 11 is divided into left and right sides, which makes it extremely easy to shrink and deform outward, and also allows for large deformation, making it very flexible and capable of being used in a variety of ways. It is possible to store items of various sizes and shapes.

The shape of the rib-like portion 12 may be various shapes such as a parallel shape, in addition to the tapered shape shown in the figure.

Moreover, the shape of the storage recess 10 may be such that the inner circumferential wall thereof is formed into a vertically elongated cylindrical shape, for example, as shown in FIG. becomes.

Further, in the embodiment shown in FIG. 5, an auxiliary groove 13 in the circumferential direction is connected to the lower part of the cut groove 12 to separate the rib-like part 11 from the bottom side of the storage recess 10.
In this embodiment, the flexibility of the rib-shaped portion 11 can be further ensured, and the adaptability to the stored items is further improved.

On the other hand, as the thermoplastic resin sheet forming the tray 1, in addition to the above-mentioned foamed polystyrene sheet, a foamed sheet made of a resin made by copolymerizing or mixing polystyrene with a polyolefin resin such as polyethylene, polypropylene, or polybutadiene has elasticity and flexibility. It has good properties and is suitable. In addition, polyvinyl chloride or other foamed resin sheets can also be used, and a single layer sheet made of non-foamed resin, a layered sheet made by laminating a non-foamed sheet or film on the foamed sheet, etc. may also be used.

According to the tray for packaging fruits, etc., constructed as described above, the rib-like portion bulges on the inner circumferential wall of the storage recess is formed with a cut groove, so that the rib-like portion has a very good quality. The elastic range is expanded, and the adaptability to the stored items is increased, so that stored items of various sizes and shapes can be stored with good stability.

Therefore, trays can be commonly used over a wide range of areas, and the number of types of trays can be reduced and the production volume can be increased in large lots, resulting in higher production efficiency and lower costs. We will be able to provide something that is effective.
