Description

The present invention relates to a method for determining the number of fruit and vegetable packages to be stacked .

At supermarkets, department stores, and other mass retailers, fruits such as bananas and mangoes, root vegetables such as radishes and carrots, fruit vegetables such as tomatoes and cucumbers, sprouts such as mung bean sprouts, fungi (mushrooms) such as shiitake and shimeji mushrooms, leafy vegetables such as broccoli, spinach, lettuce, and cabbage, and flowers or seedlings such as chrysanthemums and lilies are sometimes sold to consumers (purchasers) in the form of fruit and vegetable packages wrapped in packaging bags made of synthetic resin film with small holes that form openings (see, for example, Patent Document 1).

The packaging of fruits and vegetables in such packaging bags is carried out, for example, at a processing plant to produce fruit and vegetable packages, which are then transported in trucks or other vehicles and then displayed at mass retailers or sold by direct delivery from the factory.

When transporting by truck or the like, multiple fruit and vegetable packages are packed together in a packaging box such as a cardboard box to form a fruit and vegetable package. The fruit and vegetable packages are delivered to the home in this state, or are removed from the packaging box after transportation and storage and displayed in this state for sale at a retail store.

In the above-mentioned fruit and vegetable packaging, multiple fruit and vegetable packages are usually packed together by stacking them in the direction of gravity with the fruit and vegetable packages (synthetic resin film) roughly parallel to the bottom surface of the packaging box.

However, in a packaging method in which the fruit and vegetable packages are arranged approximately parallel to the bottom of the packaging box, simply stacking multiple fruit and vegetable packages in the direction of gravity causes the upper and lower fruit and vegetable packages to overlap, and as a result, the pores formed in the synthetic resin film, particularly in the fruit and vegetable package located at the bottom, become blocked or crushed. This causes the pores to be unable to function as openings, resulting in a problem that the freshness of the packaged fruit and vegetable cannot be sufficiently maintained for a long period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A fruit or vegetable package and a packaging method thereof will be described in detail below with reference to preferred embodiments shown in the accompanying drawings.

Before describing the fruit and vegetable package, the fruit and vegetable packages to be packaged in the fruit and vegetable package will be described below.

First Embodiment
<Fruit and vegetable packaging>
Fig. 1 is a plan view showing a first embodiment of a fruit and vegetable package to be packaged in a fruit and vegetable package, and Fig. 2 is a perspective view showing the fruit and vegetable package container in Fig. 1 in an unpackaged state. In Fig. 1 and Fig. 2, for convenience of explanation, the opening of the fruit and vegetable package container is exaggerated, and the size and ratio of the opening to the entire fruit and vegetable package container are significantly different from the actual size. In addition, the fruit and vegetable package container (first film member and second film member) is rectangular in plan view, and the direction along its long side 12 is the x direction and the direction along its short side 11 is the y direction. In addition, the direction perpendicular to the x direction and the y direction, i.e., the thickness direction of the fruit and vegetable package container (first film member and second film member), is the z direction.

As shown in FIG. 1, the fruit and vegetable packaging container 1 (hereinafter sometimes simply referred to as "packaging container 1") is bag-shaped in this embodiment and is used to package fruit and vegetable B in a sealed state within this container (inside the bag), and the fruit and vegetable package 10 (hereinafter sometimes simply referred to as "packaging body 10") has the packaging container 1 and the fruit and vegetable B packaged in a sealed state within this packaging container 1. Hereinafter, the state in which the fruit and vegetable B has not yet been packaged within the packaging container 1 will be referred to as the "unpackaged state," and the state in which the fruit and vegetable B has been packaged within the packaging container 1 will be referred to as the "packaged state."

The fruits and vegetables B to be packaged in the packaging container 1 are not particularly limited, but examples include fruits such as bananas, mangoes, plums, apples, strawberries, mandarin oranges, grapes, Japanese pears, and Western pears; root vegetables such as radishes, carrots, Chinese yams, and burdock; fruit vegetables such as tomatoes, cucumbers, eggplants, peppers, edamame, and okra; sprouts such as mung bean sprouts, soybean sprouts, and tomyo; fungi (mushrooms) such as shiitake mushrooms, shimeji mushrooms, king oyster mushrooms, maitake mushrooms, and matsutake mushrooms; leafy vegetables such as broccoli, spinach, komatsuna, bok choy, lettuce, cabbage, and asparagus; and flowers or seedlings such as chrysanthemums, lilies, and carnations. Any of these can be packaged in the packaging container 1.

These fruits and vegetables may be unprocessed, or may have been processed by washing or the like, or may be so-called cut vegetables that have been pre-processed, such as by slicing into thin strips, chopping into irregular pieces, or cutting into chrysanthemum shapes.

The packaging container 1 is used for packaging fruits and vegetables. In this embodiment, the packaging container 1 is made of a synthetic resin film formed into a bag shape, and more specifically, the bag shape is formed by overlapping a first film member 2 and a second film member 3, and the opening on the short side 11 through which the fruits and vegetables B can be put in and taken out is fused and sealed by heat sealing (thermocompression bonding) to form a sealed bag.

There are various methods for producing this packaging container 1, and they are not particularly limited. For example, two synthetic resin films are stacked on top of each other, or one synthetic resin film is folded over, and two or one of the two long sides 12 are heat-sealed to fuse the two long sides 12 together to form a cylindrical film, thereby obtaining a packaging container 1 having openings on two short sides 11 facing each other in the x direction. In such a packaging container 1, fruit or vegetable B is placed into one of the openings formed on each of the two short sides 11, and then these openings are heat-sealed to fuse and seal the openings, thereby producing a fruit or vegetable package 10 in which the fruit or vegetable is packaged in the packaging container 1.

The formation of the fruit and vegetable package 10 in which such fruit and vegetable B is packaged in the packaging container 1 is carried out, for example, at a processing factory, and this fruit and vegetable package 10 is transported by truck or the like, and then displayed at a mass retailer or sold by home delivery directly from the factory.

When two synthetic resin films are overlapped to form a bag-shaped packaging container 1, these two synthetic resin films form the first film member 2 and the second film member 3. When one synthetic resin film is folded to form the packaging container 1, the first film member 2 and the second film member 3 are formed by the folded single synthetic resin film.

The material of such synthetic resin films (first film member 2 and second film member 3) is not particularly limited, but examples include polyethylene, polypropylene, polyethylene terephthalate, polystyrene, nylon (polyamide), ethylene vinyl acetate copolymer (EVA), polybutylene succinate, polybutylene succinate adipate, and polylactic acid. The synthetic resin film may also be a semi-synthetic resin film, and examples of the material include cellophane. Any of these materials may be used alone or laminated. The packaging container 1 may also be a bag made by bonding these films with metal foil, paper, or nonwoven fabric.

The first film member 2 and the second film member 3 may also be stretched, anti-fogging, or printed, and may be coated with inorganic antibacterial agents such as silver or copper, or organic antibacterial agents such as chitin, chitosan, or allyl isothiocyanate, or these may be kneaded into the film.

When using the first film member 2 and the second film member 3 that are not suitable for heat sealing, the opening can be sealed by laminating or coating the short side 11 where the opening is provided with a sealant layer. For example, cellophane film coated with acrylic resin, and a film in which linear low density polyethylene (LLDPE) polystyrene and EVA are laminated onto polyethylene terephthalate (PET) can be used as the first film member 2 and the second film member 3.

As shown in FIG. 1, in this embodiment, the first film member 2 has a plurality of first openings 21 (first through holes) penetrating in the z direction (thickness direction), and the second film member 3 has a plurality of second openings 31 (second through holes) penetrating in the z direction. This allows the packaging container 1 to exhibit breathability that allows air to pass through even in the packaged state. In this way, in the packaging container 1, the synthetic resin film, i.e., the first and second openings 21, 31 formed in the first and second film members 2, 3, respectively, function as ventilation holes (pores) through which air passes. As a result, the packaging container 1 can maintain oxygen and carbon dioxide concentrations suitable for preserving the fruit or vegetable B, and the freshness of the fruit or vegetable B can be maintained for a long period of time.

In addition, the oxygen concentration inside the packaging container 1 varies depending on the fruit or vegetable B being packaged, but is generally 0.04-19%, and the carbon dioxide concentration is preferably 2-26%, and more preferably 0.1-10% and 5-15%. By setting the oxygen concentration and carbon dioxide concentration inside the packaging container 1 within the above ranges, the freshness of the fruit or vegetable B can be reliably maintained for a long period of time.

In addition, the oxygen transmission rate of the packaging container 1 is preferably 2500 cc/ ^m2 -day-MPa (30°C, 70% RH) to 110000 cc/ ^m2 -day-MPa (30°C, 70% RH). This allows the oxygen concentration and carbon dioxide concentration inside the packaging container 1 to be set within the above ranges relatively easily.

In a packaging container 1 having such a configuration, the first openings 21 are not limited in number, but in this embodiment, as shown in Figures 1 and 2, they are arranged in four rows at equal intervals along the x direction and four columns at equal intervals along the y direction. The first openings 21 arranged in a matrix in this manner may be referred to as "first opening 21a," "first opening 21b," ... "first opening 21o," and "first opening 21p" from the lower left to the upper right in Figure 1. Each first opening 21 is elongated and extends linearly in the x direction.

Although the number of second openings 31 is not limited, in this embodiment, they are arranged in four rows at equal intervals along the x direction and four columns at equal intervals along the y direction. The second openings 31 arranged in this matrix (lattice) may be referred to as "second opening 31a", "second opening 31b", ... "second opening 31o" and "second opening 31p" from the lower left to the upper right in FIG. 1. Each second opening 31 has the same shape and size as the first opening 21. That is, each second opening 31 is elongated and extends linearly in the x direction.

In the packaging container 1 configured as above, the length L, width W, and number (16 each in this embodiment) of the openings 21, 31 formed in the first and second film members 2, 3 are set so that the oxygen concentration and carbon dioxide concentration inside the packaging container 1, and further the oxygen permeability of the packaging container 1, are within the above-mentioned ranges. Specifically, the length L of the first opening 21 and the second opening 31 is preferably 30 μm or more and 200 μm or less, more preferably 50 μm or more and 100 μm or less, and the width w is preferably 10 μm or more and 100 μm or less, more preferably 50 μm or more and 80 μm or less.

The thickness T of the first film member 2 and the second film member 3 may be the same or different, but is preferably 0.01 mm or more and 0.1 mm or less, and more preferably 0.01 mm or more and 0.065 mm or less.

Furthermore, the amount of fruit or vegetable packed in the packaging container 1 varies depending on the type of fruit or vegetable, but is preferably set to about 10 g to 800 g per bag, and more preferably about 50 g to 400 g per bag.

The first opening 21 may be formed in the first film member 2, and the second opening 31 may be formed in the second film member 3 by cutting using a sharp blade such as a cutter, or by punching using a die that can make a cut in the desired shape. They can also be formed by laser processing.

When transported by truck or the like, multiple fruit and vegetable packages 10 like the one described above are packed in a packing box 100 to form the fruit and vegetable packages 500. For example, the fruit and vegetable packages 500 may be delivered to the home, or the fruit and vegetable packages 10 may be removed from the packing box 100 after transport and storage, and displayed as the fruit and vegetable packages 10 for sale at a retail store.

In this fruit and vegetable packaging body 500, in the present invention, a plurality of fruit and vegetable packaging bodies 10 are stacked and packed in the packing box 100 in the direction of gravity (z direction), and when the oxygen permeability of the fruit and vegetable packaging container 1 located at the top is A [cc/ ^m2 ·day·MPa (30°C·70% RH)] and the oxygen permeability of the fruit and vegetable packaging container 1 located at the bottom is B [cc/ ^m2 ·day·MPa (30°C·70% RH)], the fruit and vegetable packaging bodies 10 are stacked and packed in a quantity such that B/A is 0.5 or more and 1.0 or less.

Therefore, even if the fruit or vegetable package 10 is located at the bottom among multiple stacked fruit or vegetable packages 10 in the packaging box 100, the first and second openings 21, 31 (pores) formed in the first and second film members 2, 3 are appropriately suppressed or prevented from being blocked or crushed, and the openings 21, 31 can reliably function as ventilation holes (openings). As a result, the freshness of the fruit or vegetable B packaged in the packaging container 1 can be maintained for a long period of time.

The fruit and vegetable package 500 will be described in detail below.
<Fruit and vegetable packaging>
Fig. 3 is a perspective view showing the fruit and vegetable package shown in Fig. 1 and a packaging box for packaging the fruit and vegetable package, and Fig. 4 is a vertical cross-sectional view showing a first embodiment of the fruit and vegetable package in which a plurality of the fruit and vegetable packages shown in Fig. 1 are packaged in the packaging box. In Fig. 3 and Fig. 4, for convenience of explanation, the opening of the fruit and vegetable packaging container is exaggerated, and the size and ratio of the opening to the entire fruit and vegetable packaging container are significantly different from the actual size. In addition, the fruit and vegetable packaging container has a rectangular shape in a plan view, and the direction along the long side 12 is the x direction and the direction along the short side 11 is the y direction. In addition, the direction perpendicular to the x direction and the y direction, i.e., the thickness direction of the fruit and vegetable packaging container (the first film member and the second film member) is the z direction.

The packaging box 100 is made of a paper board such as corrugated cardboard or a resin board made of a resin material, and as shown in FIG. 3, has a rectangular bottom surface 101 and first to fourth side surfaces 102 to 105 each of which is rectangular and stands upright from the four sides (edges) of the bottom surface 101. The bottom surface 101 and the first to fourth side surfaces 102 to 105 define an internal space 120 having an opening 125 that opens on the opposite side of the bottom surface 101.

The packaging box 100 further has first to fourth lids 112 to 115 each having a rectangular shape and rotatably attached to the side (edge) of the first to fourth side surfaces 102 to 105 opposite the bottom surface 101. The first to fourth lids 112 to 115 are folded toward the internal space 120 (inside) so as to be approximately parallel to the bottom surface 101, thereby forming a top surface 110 that closes the opening 125.

In other words, in this embodiment, in the packaging box 100, the top surface 110 formed by the first to fourth lid bodies 112 to 115 faces the bottom surface 101, and further, the top surface 110 and the bottom surface 101 are arranged so as to straddle the multiple side surfaces 102 to 105, and the top surface 110 can be opened and closed by rotating the first to fourth lid bodies 112 to 115.

The fruit and vegetable packaging body 500 (hereinafter sometimes simply referred to as "packaging body 500") comprises such a packaging box 100 and a plurality of packaging bodies 10 (14 in this embodiment) packed within the packaging box 100, i.e., stored in the internal space 120 of the packaging box 100 (see Figure 4).

In the present invention, a plurality of packages 10 are packed in a packing box 100 by stacking them in the direction of gravity (z direction), and when the oxygen transmission rate of the uppermost package container 1 is A [cc/ ^m2 ·day·MPa (30° C.·70% RH)] and the oxygen transmission rate of the lowermost package container 1 is B [cc/ ^m2 ·day·MPa (30° C.·70% RH)], the fruit and vegetable packages 10 are stacked and packed in such a number that B/A is 0.5 to 1.0. That is, in this embodiment, the packages 10 are stored in the internal space 120 with one of the first and second film members 2, 3 on the lower side (bottom surface 101) so that the first and second film members 2, 3 of the packages 10 are substantially parallel to the bottom surface 101. The multiple packaging bodies 10 are stored (packed) in the internal space 120 with seven packaging bodies 10 stacked in the thickness direction (z direction) of the bottom surface 101 to form a set, and two sets lined up in the surface direction (y direction) of the bottom surface 101.

In this way, when the packages 10 are stacked in the internal space 120 so as to be substantially parallel to the bottom surface 101, i.e., stacked along the direction of gravity, the fruit and vegetable packages 10 are packed in such a number that the relationship B/A between the oxygen transmission rate A [cc/ ^m2 ·day·MPa (30°C·70% RH)] of the package container 1 located at the top and the oxygen transmission rate B [cc/ ^m2 ·day·MPa (30°C·70% RH)] of the package container 1 located at the bottom is 0.5 or more and 1.0 or less. Therefore, it is possible to reliably prevent the weight of the package 10 located at the top from being unnecessarily applied to the package 10 located at the bottom. Therefore, it is possible to reliably prevent the first and second openings 21, 31 (pores) formed in the first and second film members 2, 3 in the package 10 located at the bottom from being blocked or crushed. Therefore, the first and second openings 21, 31 (pores) can be made to function reliably as openings, so that the freshness of the packaged fruit or vegetable B can be maintained for a long period of time even in the packaging body 10 located at the bottom.

The relationship B/A between the oxygen permeability A of the packaging container 1 located at the top and the oxygen permeability B of the packaging container 1 located at the bottom may be 0.5 or more and 1.0 or less, but is preferably 0.6 or more and 1.0 or less, and more preferably 0.85 or more and 1.0 or less. This allows the above-mentioned effect to be exhibited more significantly.

In this embodiment, as shown in FIG. 4, the packaging body 10 is stacked in the direction of gravity and stored in the internal space 120 so that the first and second film members 2, 3 of the packaging body 10 are approximately parallel to the bottom surface 101, but this is not limited to the case where they are approximately parallel, and the packaging body 10 may be stored in the internal space 120 with the first and second film members 2, 3 slightly inclined with respect to the bottom surface 101. That is, the first and second film members 2, 3 of the fruit and vegetable packaging body 10 may be perpendicular or slightly inclined with respect to the bottom surface 101 of the packaging box 100. Specifically, the angle between the first and second film members 2, 3 and the bottom surface 101, including the case where they are parallel, is preferably 0° or more and 15° or less, and more preferably 0° or more and 5° or less. When the angle between the first and second film members 2, 3 and the bottom surface 101 is within the above range, the application of the present invention can more accurately suppress or prevent the first and second openings 21, 31 (pores) formed in the first and second film members 2, 3 from being blocked or crushed, even in the package 10 located on the lower side.

Here, the angle between the first and second film members 2, 3 and the bottom surface 101 in the package 10 refers to the angle between the bottom surface 101 and a tangent line at the center of gravity of the first and second film members 2, 3 that is the shortest distance from the bottom surface 101, that is, in this embodiment, the angle between the bottom surface 101 and a tangent line extending in the longitudinal direction (y direction) of the first and second film members 2, 3 at the center of gravity of the first and second film members 2, 3.

As described above, the relationship B/A between the oxygen permeability A of the uppermost packaging container 1 and the oxygen permeability B of the lowermost packaging container 1 is set within the range of 0.5 to 1.0 by adjusting the number of packaging bodies 10 stacked. In addition to adjusting the number, the size of B/A may be adjusted by stacking upper and lower fruit and vegetable packaging bodies 10 alternately so that the short sides 11 and long sides 12 face the same direction, rather than stacking them with the short sides 11 facing the same direction as in this embodiment. Furthermore, the size of B/A can also be adjusted by stacking the packaging containers 1 so that the openings 21, 31 are biased toward one of the two short sides 11 in the film members 2, 3, and stacking them so that one short side 11 overlaps the other short side 11.

The package 500 in which the packages 10 are stacked in the direction of gravity in the internal space 120 can be obtained, for example, by a packaging method including a storage process in which the packages 10 are stacked and stored in the package box 100 so that the angles between the first and second film members 2, 3 and the bottom surface 101 are parallel when the top surface 110 of the package box 100 is open, and a closing process in which the package 500 is obtained by closing the top surface 110.

The packaging box 100 is not limited to the case where the top surface 110 is openable as in this embodiment, but may have at least one of the first to fourth side surfaces 102 to 105 openable, or may omit the formation of the top surface 110. Note that when the formation of the top surface 110 is omitted, the process of leaving the top surface 110 open and further closing the top surface 110 is omitted in the packaging method described above.

Furthermore, in this embodiment, the openings 21, 31 are described as being configured as through holes penetrating the film members 2, 3 in the z-direction, but the openings 21, 31 only need to have a lower oxygen permeability than the film members 2, 3, and may be configured as, for example, thin-walled portions that are thinner than the film members 2, 3.

Second Embodiment
A second embodiment of the fruit and vegetable package and the fruit and vegetable packaging body will be described below, focusing on the differences from the first embodiment described above, and a description of similar points will be omitted.

<Fruit and vegetable packaging>
Fig. 5 is a perspective view showing a second embodiment of a fruit and vegetable package to be packaged in a fruit and vegetable package. For convenience of explanation, Fig. 5 shows an exaggerated view of the opening of the fruit and vegetable packaging container, and the size and ratio of the opening to the entire fruit and vegetable packaging container are significantly different from the actual size. The fruit and vegetable packaging container is rectangular in plan view, and the direction along its long side is the x-direction and the direction along its short side is the y-direction. The direction perpendicular to the x-direction and y-direction, i.e., the thickness direction of the fruit and vegetable packaging container (first film member), is the z-direction.

Here, this embodiment is the same as the first embodiment, except that the configuration of the fruit and vegetable packaging container that stores (packages) the fruit and vegetable B is different.

As shown in FIG. 5, the fruit and vegetable packaging container 1A (hereinafter sometimes simply referred to as "packaging container 1A") in this embodiment has an overall box-like shape and is used to package fruit and vegetable B in a sealed state within this container (inside the box), and the fruit and vegetable package 10A (hereinafter sometimes simply referred to as "packaging body 10A") has the packaging container 1A and the fruit and vegetable B packaged (stored) in a sealed state in this packaging container 1A.

This packaging container 1A has a storage member 5 with a recess 55 and a first film member 2, and is an airtight container that seals the fruit or vegetable B within the recess 55 by sealing the recess 55 with the first film member 2.

In the packaging container 1A, the first film member 2 has the same configuration as that described in the first embodiment, and the storage member 5 has a flat bottom 51 and a side portion 52 standing upright from the edge of the bottom 51, forming a recess 55 with an opening 54. In the packaging container 1A having such a configuration, after storing fruit or vegetable B through the opening 54, the top 53 of the side portion 52 is sealed with the first film member 2 by heat fusion or the like, thereby forming a fruit or vegetable package 10A in which the fruit or vegetable is packaged in the packaging container 1A.

The material of the storage member 5 is not particularly limited, but examples include polyolefins such as polypropylene, polyester, polystyrene, etc.

Similar to the fruit and vegetable packaging 10 described in the first embodiment, multiple fruit and vegetable packaging bodies 10A as described above are packed in a packaging box 100 during transportation by truck or the like to form the fruit and vegetable packaging body 500A.

<Fruit and vegetable packaging>
Fig. 6 is a vertical cross-sectional view showing a second embodiment of a fruit and vegetable package in which a plurality of the fruit and vegetable packages shown in Fig. 5 are packaged in a packaging box. In Fig. 6, for convenience of explanation, the opening of the fruit and vegetable packaging container is exaggerated, and the size and ratio of the opening to the entire fruit and vegetable packaging container are significantly different from the actual size. In addition, the fruit and vegetable packaging container has a rectangular shape in a plan view, and the direction along the long side is the x-direction and the direction along the short side is the y-direction. In addition, the direction perpendicular to the x-direction and the y-direction, i.e., the thickness direction of the fruit and vegetable packaging container (first film member) is the z-direction.

The fruit and vegetable packaging body 500A (hereinafter sometimes simply referred to as "packaging body 500A") comprises a packaging box 100 similar to that of the first embodiment, and a plurality of packaging bodies 10A (14 in this embodiment) stored in the internal space 120 of the packaging box 100 (see FIG. 6).

The packaging bodies 10A are stored in the packaging box 100 by stacking them in the direction of gravity on the bottom surface 101 so that they are approximately parallel to the bottom surface 101. More specifically, in this embodiment, the multiple packaging bodies 10A are stored (packed) in the internal space 120 with two sets of packaging bodies 10A arranged side by side in the surface direction (y direction) of the bottom surface 101, with seven packaging bodies 10A stacked in the thickness direction (z direction) of the bottom surface 101 as one set.

In this way, when the packaging bodies 10A are stacked in the direction of gravity so as to be approximately parallel to the bottom surface 101 and stored in the internal space 120, the number of packaging bodies 10A (7 in this embodiment) that are stacked and packed so that B/A is 0.5 to 1.0 can be obtained, and the same effect can be obtained as when the packaging body 10 of the first embodiment is stored in the internal space 120.

Third Embodiment
Hereinafter, a fruit and vegetable package and a third embodiment of a fruit and vegetable package will be described, focusing on the differences from the first embodiment described above, and a description of similar points will be omitted.

In this embodiment, the fruit and vegetable packaging container 1 that stores (packages) the fruit and vegetable B has the same configuration as the fruit and vegetable packaging container 1 described in the first embodiment, and is similar to the first embodiment except that the configuration of the packaging box 100B in which the fruit and vegetable packaging container 1 is packed is different.

Therefore, in the following, we will omit the description of the fruit and vegetable packaging 10 and instead describe the fruit and vegetable packaging 500B in which multiple fruit and vegetable packaging 10 are packed in a packaging box 100B.

<Fruit and vegetable packaging>
Fig. 7 is a vertical cross-sectional view showing a third embodiment of a fruit and vegetable package in which a plurality of the fruit and vegetable packages shown in Fig. 1 are packaged in a packaging box. In Fig. 7, for convenience of explanation, the opening of the fruit and vegetable packaging container is exaggerated, and the size and ratio of the opening to the entire fruit and vegetable packaging container are significantly different from the actual size. In addition, the fruit and vegetable packaging container has a rectangular shape in a plan view, and the direction along its long side 12 is the x-direction and the direction along its short side 11 is the y-direction. In addition, the direction perpendicular to the x-direction and the y-direction, i.e., the thickness direction of the fruit and vegetable packaging container (the first film member and the second film member), is the z-direction.

As shown in FIG. 7, the packaging box 100B has a rectangular bottom surface 101, first to fourth side surfaces 102 to 105 each extending from the four sides (edges) of the bottom surface 101, and a rectangular top surface 110 facing the bottom surface 101, and the bottom surface 101, the first to fourth side surfaces 102 to 105, and the top surface 110 define an internal space 120. In this embodiment, the packaging box 100B has a plurality of (two in this embodiment) partition members 130 (auxiliary devices) arranged along the surface direction (y direction) of the bottom surface 101. As a result, the internal space 120 is divided into a plurality of (three in this embodiment) compartments 135.

In this embodiment, the packaging box 100B has three compartments 135, each of which is provided with a packing box 100B having such a configuration. In each of the three compartments 135, two packages 10 are stacked in the thickness direction (z direction) of the bottom surface 101, and two sets are stored (packed) side by side in the surface direction (y direction) of the bottom surface 101. By storing the stacked packages 10 in the compartments 135 separated by the partition members 130 in this manner, the relationship B/A between the oxygen permeability A of the fruit and vegetable packaging container 1 located at the top and the oxygen permeability B of the fruit and vegetable packaging container 1 located at the bottom can be more easily set to a range of 0.5 to 1.0. Therefore, the same effect as that of storing the packages 10 of the first embodiment in the internal space 120 can be more reliably obtained.

As in the first embodiment, in the packaging box 100B, it is sufficient that at least one of the first to fourth side surfaces 102 to 105 and the top surface 110 is openable and closable, but it is preferable that one of the first to fourth side surfaces 102 to 105 is openable and closable. By configuring the side surface to open in this manner, an opening is formed in the side surface, and in the packaging method for packaging the packages 10 in the packaging box 100B, the stacked packages 10 can be stored relatively easily in the compartment 135 partitioned by the partition member 130.

Fourth Embodiment
A fourth embodiment of the fruit and vegetable package and the fruit and vegetable packing will be described below, focusing on the differences from the first embodiment described above, and a description of similar points will be omitted.

In this embodiment, the fruit and vegetable packaging container 1 that stores (packages) the fruit and vegetable B has the same configuration as the fruit and vegetable packaging container 1 described in the first embodiment, and is similar to the first embodiment except that the configuration of the packaging box 100C that packs the fruit and vegetable packaging container 1 is different.

Therefore, in the following, we will omit the description of the fruit and vegetable packaging 10 and instead describe the fruit and vegetable packaging 500C in which multiple fruit and vegetable packaging 10 are packed in a packaging box 100C.

<Fruit and vegetable packaging>
Fig. 8 is a vertical cross-sectional view showing a fourth embodiment of a fruit and vegetable package in which a plurality of the fruit and vegetable packages shown in Fig. 1 are packaged in a packaging box. In Fig. 8, for convenience of explanation, the opening of the fruit and vegetable packaging container is exaggerated, and the size and ratio of the opening to the entire fruit and vegetable packaging container are significantly different from the actual size. In addition, the fruit and vegetable packaging container has a rectangular shape in a plan view, and the direction along its long side 12 is the x-direction and the direction along its short side 11 is the y-direction. In addition, the direction perpendicular to the x-direction and the y-direction, i.e., the thickness direction of the fruit and vegetable packaging container (the first film member and the second film member), is the z-direction.

8, the packaging box 100C has a rectangular bottom surface 101, first to fourth side surfaces 102 to 105 each extending from the four sides (edges) of the bottom surface 101, and a rectangular top surface 110 facing the bottom surface 101, and an internal space 120 is defined by the bottom surface 101, the first to fourth side surfaces 102 to 105, and the top surface 110. In this embodiment, the packaging box 100C has a base 140 (auxiliary tool) for raising the bottom to define a space 150 between the package 10 located at the bottom and the bottom surface 101. With the base 140 placed on the bottom surface 101, the multiple packages 10 are arranged on the base 140 in two sets, with six packages stacked together in the packaging box 100C, lined up in the surface direction (y direction) of the base 140.

In this way, in the packaging box 100C, by stacking a plurality of packages 10 in the direction of gravity on the base 140 arranged on the bottom surface 101, a space 150 is located between the package 10 located at the bottom and the bottom surface 101. Therefore, even if moisture is attached to the bottom surface 101 of the packaging box 100C, it is possible to reliably prevent the package 10 located at the bottom from coming into contact with the bottom surface 101 of the packaging box 100C. Therefore, since it is possible to reliably prevent moisture attached to the bottom surface 101 from being taken into the packaging body 10 through the first and second openings 21, 31 of the first and second film members 2, 3 of the packaging body 10, the freshness of the packaged fruit and vegetable B can be maintained almost uniformly for a long period of time in each packaging body 10 packed in the fruit and vegetable packaging body 500C.

Fifth Embodiment
Hereinafter, the fifth embodiment of the fruit and vegetable package and the fruit and vegetable packing will be described, focusing on the differences from the first embodiment described above, and a description of similar points will be omitted.

In this embodiment, the configuration of the packaging box 100 in which the fruit and vegetable packaging container 1 is packaged is the same as in the first embodiment, but the fruit and vegetable packaging container 1 in which the fruit and vegetable B is stored (packaged) has a different configuration from the fruit and vegetable packaging container 1 described in the first embodiment.

Therefore, in the following, we will omit the description of the fruit and vegetable packaging body 500 and explain the fruit and vegetable packaging body 10 that is packed in multiple pieces in the packaging box 100.

<Fruit and vegetable packaging>
Fig. 9 is a plan view showing a fifth embodiment of a fruit and vegetable package to be packaged in a fruit and vegetable package, and Fig. 10 is a perspective view showing the fruit and vegetable packaging container in Fig. 9 in an unpackaged state. In Figs. 9 and 10, the opening of the fruit and vegetable packaging container is exaggerated for ease of explanation, and the size and ratio of the opening to the entire fruit and vegetable packaging container are significantly different from the actual size. In addition, the fruit and vegetable packaging container has a rectangular shape in a plan view, and the direction along the short side is the x-direction and the direction along the long side is the y-direction. In addition, the direction perpendicular to the x-direction and the y-direction is referred to as the thickness direction of the fruit and vegetable packaging container (the first film member and the second film member).

As shown in FIG. 9, in this embodiment, as in the first embodiment, in the packaging container 1, the first film member 2 has a plurality of first openings (first through holes) 21 penetrating in its thickness direction, and the second film member 3 has a plurality of second openings (second through holes) 31 penetrating in its thickness direction.

In the present embodiment, in the packaging container 1 having such a configuration, each of the first openings 21 and each of the second openings 31 are elliptical with the longer side in the x direction, as shown in Figures 9 and 10.

Thus, even though the packaging container 1 has the elliptical first opening 21 and second opening 31, the first opening 21 and second opening 31 function as vents (pores) through which air passes, so the packaging container 1 exhibits breathability that allows air to pass through in the packaged state. As a result, the packaging container 1 can maintain oxygen and carbon dioxide concentrations suitable for preserving the fruit or vegetable B, and the freshness of the fruit or vegetable B can be maintained for a long period of time.

Therefore, the same effect as the package 500 described in the first embodiment can be obtained when the package 10 in which the fruit or vegetable B is packaged in the packaging container 1 of this embodiment is packaged in a packaging box 100.

The first opening 21 and the second opening 31 are not limited to being elliptical, but may be circular, as long as they are circular.

Although the embodiment of the quantity determination method of the present invention has been described above with reference to the drawings, the present invention is not limited thereto, and each part constituting the fruit and vegetable package (fruit and vegetable packaging container) can be replaced with any other part capable of exerting the same function. In addition, any other component can be added.

Furthermore, the quantity determination method of the present invention may be a combination of any two or more configurations (features) of the above-described embodiments.

Furthermore, in the packaging container 1 in the above-mentioned embodiments 1 and 3 to 5, multiple openings are formed in both the first film and the second film, but this is not limited to the above, and multiple openings may be formed in at least one of the first film or the second film. Also, the number of openings formed in both or at least one of the first film and the second film is not limited to multiple, and may be one.

In addition, the shapes of the first opening and the second opening are linear or circular (elliptical) in each of the above embodiments, but are not limited thereto, and may be, for example, a shape having curved portions such as an S-shape, U-shape, semicircle, or wave shape, or a shape having corners such as a V-shape, X-shape, L-shape, H-shape, T-shape, W-shape, or C-shape.

Specific examples of the present invention are described below. Note that the present invention is not limited to these examples.

1. Study of packaging bags for packaging spinach as a fruit and vegetable 1-1. Production of fruit and vegetable packaging and fruit and vegetable package (Example 1A)
A 25 mm thick biaxially oriented polypropylene film that had been anti-fog treated was folded and then two opposing sides were fused by heat sealing (thermocompression bonding) to produce a packaging container 1 with inner dimensions of 200 x 400 mm. Then, this packaging container 1 was irradiated with a laser at 300 positions from the first film side with the first film facing up, to provide 300 first and second openings, each with a length L of 150 μm and a width W of 80 μm, in the first and second films. As a result, a packaging container 1 was obtained in which the first openings and the second openings were entirely overlapped (matched) as shown in FIG. 1.

Then, about 100 g of spinach stalks were placed in the packaging container 1 and the opening was sealed with a heat seal to obtain a package 10 containing the spinach stalks.

Then, the seven packages 10 were stacked in the direction of gravity and stored in a packaging box 100 made of cardboard to obtain the fruit and vegetable package 500 of Example 1A.

The oxygen permeability A of the packaging container 1 located at the top and the oxygen permeability B of the packaging container 1 located at the bottom were measured using an oxygen permeability measuring device ("OXYTRAN (registered trademark) OX-TRAN 2/21" manufactured by MOCON Corporation) and were found to be 68,000 cc/ ^m2 -day-MPa (30°C, 70% RH) and 35,000 cc/ ^m2 -day-MPa (30°C, 70% RH), respectively.
