Description

The present invention relates to a storage container and a storage structure for transferring fruits, and more particularly to a storage container sheet, a storage container and a storage structure suitable for small fruits such as figs, loquats and strawberries whose shape deviates from the spherical shape.

In recent years, apart from citrus fruits wrapped in tough skins, medium-sized and larger fruits such as apples and pears are shipped one by one wrapped in a net-like cushioning material mainly made of polyolefin foam. , It is taken out and displayed in the store.
In some cases, they are put in a special plastic tray for transportation, stored in a cardboard box, etc., and then taken out from there and displayed in another container at the store. Even with the same fruits and vegetables, some of them have been moved to different containers that look good in high-end stores and those with high prices.

However, it is difficult to wrap small fruits such as figs, loquats, and strawberries, which are largely out of the spherical shape, with the cushioning material as described above, and the efficiency is low. Therefore, several pieces are packed side by side in a dish-shaped transparent container with shallow corners, and a transparent film is placed on top of the container. A plurality of these are packed in a box made of cardboard or the like and transported, and are taken out for each of the above-mentioned transparent dish-shaped containers at the store at the transportation destination and arranged at the store. However, with such a packaging method, fruits collide with each other during transportation, and the side of the fruit comes into contact with the side of another fruit or the bottom of the container, which damages and deforms the fruit, reduces its taste and reduces its commercial value. There is a high possibility that it will be made to last, and it is difficult to make it last longer in terms of freshness and preservation.

In order to eliminate such inconvenience, for example, with respect to strawberries, a container in which strawberries are formed in a concave shape so as to be arranged in parallel with the bottom of the container tilted at an angle has been proposed (for example, Patent Document 1). ..
Further, a strawberry packaging container has been proposed in which a bowl-shaped strawberry holding portion is formed and a Y-shaped or radial stem insertion portion is provided in the center of the bottom (for example, Patent Document 2).

However, although these containers have concave curved parts and bowl-shaped holding parts for arranging strawberries, they are not completely individually wrapped, so adjacent strawberries collide with each other due to vibration during handling and transportation, and strawberries. The problem that the strawberry is damaged by contact with the side surface of the strawberry and the bottom of the concave curved portion or the bowl-shaped holding portion and the taste is lost cannot be solved.
In addition, these containers are deformed or scratched because the strawberries come into contact with the bottom of the container, that is, the concave curved portion or the bottom of the bowl-shaped holding portion, and the total gravity of the strawberries is applied to the lower surface of the strawberries that come into contact with the bottom of the container. It becomes easy, and it is difficult to prolong the freshness and preservation.

In view of this situation, the present invention solves the problem that fruits collide with each other during transportation and come into contact with the side surface of the fruit or the bottom of the container to damage the fruit, resulting in a loss of taste or freshness. It is an object of the present invention to provide a fruit storage container sheet, a storage container and a storage structure having good storage workability, whether by manual work or mechanical work.

The present invention has been made to achieve the above object, and a feature of the present invention is a fruit composed of a resin or paper sheet, a circular or polygonal bent portion, and a radial cut portion. A fruit in which a holding portion is formed , a plurality of circular or polygonal bent portions are provided concentrically, and an easy-cut portion is continuously provided between each bent portion with a radial cut portion. A sheet for storage containers.
Another feature of the present invention is the above-mentioned fruit storage container sheet in which a circular bent portion is formed by a notch .
Yet another feature of the present invention is the above-mentioned fruit storage container sheet in which the center of the radial cut portion is formed in an arc shape.
Yet another feature of the present invention is the above-mentioned fruit storage container sheet in which the sheet is made of foamed paper or laminated foamed paper.
Yet another feature of the present invention is the above-mentioned fruit storage container sheet in which a plurality of fruit holding portions are formed.
Yet another feature of the present invention is a folded portion in which the circular or polygonal bent portion of the above-mentioned fruit storage container sheet is bent into a mountain fold, and a folded portion defined by an adjacent radial cut portion. It is a fruit storage container in which a fruit holding portion is formed.
Yet another feature of the present invention is a fruit storage structure in which the fruit is supported by the fruit holding portion of the above-mentioned fruit storage container sheet , and the lower end of the fruit is stored in a free state.
Yet another feature of the present invention is a fruit storage structure in which the fruit is a fig, loquat, or strawberry and is stored with the fruit axis facing downward.

According to the fruit storage container sheet, the storage container, and the storage structure of the present invention, the fruits are individually stored in the fruit holding container one by one, so that the fruits collide with each other during transportation or handling and cause scratches. There is no such thing as sticking.
Further, the fruit is supported in the fruit storage container by a circular or polygonal bent portion and a folded portion that is bent from the bent portion and hangs diagonally downward or downward, and the lower end of the fruit is stored in a free state. Therefore, the conventional trouble that the lower part of the fruit comes into contact and is easily damaged is solved.
In particular, the folding part that hangs diagonally downward repels upward to return to the original state, so the folding part strongly adheres to and supports the side surface of the fruit, and is suitable for vibration during transportation and handling. Can be supported and protected.

FIG. 1 shows a sheet for a fruit storage container of the present invention, and FIG. 2 shows a fruit storage container made of the sheet.
As shown in FIGS. 1 and 2, the fruit storage container sheet 1 of the present invention is made of a resin, paper, or laminated plastic sheet, and has a circular or polygonal bent portion 2 and a radial shape. It is characterized in that a fruit holding portion 5 including the notch portion 3 of the above is formed.

Further, in the fruit storage container 11 of the present invention, the circular or polygonal bent portion 2 of the fruit storage container sheet 1 is bent into a mountain fold, and the bent portion 2 and the adjacent radial cut portion 2 are bent. The fruit holding portion 5 is formed by the folding portion 4 defined by 3.

FIG. 2 shows an example in which figs are stored in a fruit storage container 11. The figs 12 have a folded portion 2 after being folded into a mountain fold and a folded portion defined by an adjacent radial cut portion 3. It is housed by the fruit holding portion 5 formed by 4. The fig 12 is preferably stored with its fruit axis facing downward, and its lower end is stored in a free state (in a state of non-contact with a packaging box or the like).

Therefore, in practice, as shown in FIG. 3, the fruit storage container 11 of the present invention can be used by being stretched in a packaging box 13 made of corrugated cardboard, plastic corrugated cardboard, resin, foamed resin, wood, or the like. A support column or a support column wall 14 can be provided in the packaging box 13 as needed.

As shown in FIG. 4, the circularly bent portion 2 can be partially thinned by, for example, by engraving a notch (notch) in order to facilitate bending. By providing such a notch 6 in a circular shape, it can be easily bent into a circular shape, and the folded portion 5 after being bent has a predetermined circular shape and there is no angular portion, so that the fruit is surrounded. It can be held evenly from the surface, and there is no risk of damage or deformation.

On the other hand, when the notch 6 is not used, as shown in FIG. 5, the bent portion 2 after being bent has an octagonal shape in the illustrated example, and in the case of a soft fruit, it may be deformed into an octagonal shape. However, as shown in the figure, when the fruit is stored, the force that pushes each side outward works, and on the contrary, the holding power of the fruit is enhanced by the appropriate cushioning property, and it approaches a circular shape, so that the fruit is actually deformed. The fear is small.
In the present invention, the octagonal shape shown in the present invention may be increased in number if a more circular shape is desired. Further, the polygonal bent portion 2 can also be partially thinned by engraving a notch (notch).
In the present invention, at least one fruit holding portion 5 is provided, and preferably a plurality of fruit holding portions 5 are provided. The number of pieces to be provided cannot be unconditionally specified depending on the size of the fruit, the size of the packaging box, etc., but usually the number may be the number traded in the industry, for example, in the case of figs and loquats, it is often about 4 to 20 pieces.
The circular or polygonal bent portion 2 may be bent in advance, or the fruit may be placed in the bent portion 2 and pushed downward at the same time as being bent.

The material of the sheet for the fruit storage container of the present invention is preferably one having an appropriate cushioning property, and examples thereof include a resin film, a foamed resin sheet, a foamed paper, and a plastic laminated paper on which a resin is laminated. The thickness of the sheet may be appropriately determined depending on the type of material, etc., but it is approximately 0.1 to 0.3 mm for films and papers, and approximately 1 to 3 mm for foamed resin sheets, foamed papers, and their laminates. is there.
The resin is not particularly limited, and examples thereof include polyolefin resins such as polyethylene and polypropylene, polystyrene resins, vinylidene chloride resins, polyamide (nylon) resins, and polyester resins. In particular, polystyrene resins and polyester resins have high transparency and contents. Molding from a film or sheet into a container is convenient because the object can be confirmed, the rigidity is high, and the deep drawing formability is excellent. Further, biodegradable plastics such as polylactic acid resin, polybutylene succinate, polyamide 11, polyhydroxybutyric acid and the like, biomass plastics and the like can also be used.
The paper is not particularly limited, and examples thereof include kraft paper, woodfree paper, parchment paper, and glassine paper. These materials can be adopted in consideration of oxygen permeability, carbon dioxide permeability, gas barrier property, moisture barrier property and the like.

6 and 7 show another sheet for a fruit storage container of the present invention and a fruit storage container made of the sheet.
As shown in FIGS. 6 and 7, a plurality of circular or polygonal bent portions 2 and 2a are provided concentrically (two in this example), and an easily cut portion 7 is provided between the bent portions 2 and 2a. , It is provided continuously with the radial notch 3.

Therefore, for example, in the case where the size of the fruit (fig) is large and the bent portion 2 has a circular shape or a polygonal shape, the easy cutting portion 7 is cut and the circle is formed when the fruit protrudes too much upward and cannot be stably stored. A bent portion 2a having a shape or a polygonal shape is bent into a mountain fold, and the large-diameter bent portion 2a after being bent, and the folded portion 4 and the easy-cut portion 7 formed by the adjacent radial cut portions 3 are cut. The fruit holding portion 5 is formed by the large folding portion 4a formed. As a result, it is possible to stably store large fruits.

It is desirable that the easy-to-cut portion 7 can be cut without using a cutting tool such as a knife, and examples thereof include a cutting line such as a perforation.
The number of concentric bent portions is not particularly limited, but the size of fruits is generally classified into S, L (2L, 3L, 4L), and M, so that two or three can be stored. It is desirable to provide it.

8 and 9 show still another fruit storage container sheet of the present invention and a fruit storage container made of the sheet.
In this example, the center of the radial cut portion is formed in an arc shape. That is, the tip of the folding portion 4b defined by the adjacent radial cutting portions 3 has an arc shape, and even if the tip of the folding portion 4b hits a fruit or a finger, there is no risk of scratches or injury.

10 and 11 show still another fruit storage container sheet of the present invention and a fruit storage container made of the sheet.
In this example, both the radial cut portion 3a and the easy cut portion 7a are wavy, so that the large fold portion 4c defined by the adjacent radial cut portion 3a and the easy cut portion 7a is cloud-shaped or gourd. It is a mold and rich in design. Further, since the tip of the folded portion 4c is also arcuate, there is no risk of damaging the fruit or fingers.

The fruit storage container of the present invention is suitable for fruits that are small in shape and deviate from the spherical shape, and is particularly suitable for figs, loquats, and strawberries.
The fruit storage container containing these fruits is usually protected by a cushioning material such as a expanded polystyrene sheet or a non-woven fabric on the upper part of the fruit, and is covered with a lid and used for transportation or the like.

Hereinafter, the present invention will be described in more detail with reference to examples, but these are not intended to limit the present invention.

Example 1
Twelve figs from Awaji harvested in June this year (variety: Masui Dauphin; size: L or 2L with a maximum diameter of about 60 mm) are shown in Fig. 1 and Fig. 2 in the polyester fruit storage container (however, the number of fruit holding parts is Twelve figs were stored in the fruit holding part (the diameter of the folded part was about 70 mm, the number of folded parts was eight, and the length of the folded part was about 35 mm) so that the shaft part of the fruit was on the bottom side. Twelve containers containing the figs were placed in a cardboard packaging box, the upper surface of the fig was protected with a cushioning material made of foamed polystyrene sheet, and the figs were packaged for 60 minutes using a random vibration tester according to JIS-K-602: 2004. A cargo-vibration test (vibration only in the vertical direction) was carried out. The results showed that the figs had excellent packaging effect without major deformation or surface scratches.

Example 2
A container containing figs similar to that in Example 1 was placed in a cardboard packaging box, and a ship transportation test was conducted as a container cargo at a temperature of 1 ° C. for about 4 days. The result after transportation was that the figs were not deformed or the surface was scratched, and the packaging effect was excellent.

Comparative Example According to the current method, 12 figs were stored in two polyester cases containing 6 figs used in the example and placed in a cardboard box, and the same vibration test as in Example 1 was carried out. As a result, the epidermis of figs was rubbed and scratches were seen on the side of the fruit, and the epidermis was significantly damaged especially at the bottom of the fruit where the shaft of the fruit hits.

As described above, according to the fruit storage container sheet, the fruit storage container, and the fruit storage structure of the present invention, the fruits are individually stored in the fruit storage container, so that the fruits collide with each other during transportation and handling. There is no damage caused by fitting or rubbing.
Further, since the fruit is supported in the fruit storage container by a circular or polygonal bent portion and a folded portion that is bent from the bent portion and hangs down, the lower end of the fruit is stored in a free state. The trouble that the contacting part is easily damaged is solved.
