Description

[Technical Field]

[0001] The present invention relates to a storage tray. [Background technology]

[0002] A storage tray for individually storing fresh produce such as fruit has been proposed in the past, as shown in Patent Document 1. This device is said to be able to solve the problem of freshness decreasing at the time of sale in stores by reducing the accumulation of ethylene gas, which causes fresh produce to deteriorate during distribution. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 1-63671 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the loss of freshness of fresh produce is not only due to the accumulation of ethylene gas. For example, the loss of freshness of fresh produce is also affected by factors such as compression and scratches on the produce before it reaches the consumer, as well as the moisture level of the surface of the fresh produce.

[0005] In contrast to this, in Patent Document 1, a member in which an unfoamed resin film is laminated and bonded onto a resin sheet layer is provided with recesses for storing individual fresh products. As a result, fresh products do not collide with each other, but there is a risk that the fresh products may move inside the recesses, causing compression or scratches on the fresh products.

[0006] Therefore, the present invention has been made to solve the above problems, and its object is to provide a storage tray that can prevent compression forces and scratches that are applied to fresh produce before it reaches the consumer while ensuring appropriate breathability. [Means for solving the problem]

[0007] The present invention provides a storage tray comprising a frame structure having a base portion and a frame body supported by the base portion, and a resin sheet held by the frame structure, in which one or more fresh items are held by the resin sheet, wherein the resin sheet has lower rigidity than the frame body, and when the one or more fresh items are held, the portions in which alternating cuts are formed extend and form a net ornament shape, so that the load generated on the resin sheet by the one or more fresh items is entirely supported by the frame body, thereby solving the above-mentioned problem.

[0008] In the present invention, the resin sheet has lower rigidity than the frame body, and when one or more fresh items are held in the resin sheet, the alternating slits stretch and form a net-like ornament. This allows the resin sheet holding the fresh items to stretch extremely easily, significantly reducing the compressive force applied to the fresh items. Furthermore, because the surface of the resin sheet is smooth and adheres reasonably closely to the surface of the fresh items, the portion of the resin sheet in contact with the fresh items also moves as the fresh items move. This prevents the fresh items from being rubbed against the resin sheet. At the same time, the resin sheet does not absorb moisture from the fresh items, and the net-like ornament shape allows the fresh items to breathe properly without depriving them of moisture.

[0009] The frame body is configured to support all of the load on the resin sheet caused by one or more fresh products. That is, even if the resin sheet is bent by one or more fresh products, the resin sheet is kept out of contact with anything other than the frame body. In other words, it is possible to prevent compressive force from anything other than the resin sheet from being applied to the one or more fresh products. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a storage tray that can prevent compression forces and scratches that are applied to fresh produce before it reaches the consumer, while ensuring appropriate breathability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] An example of a first embodiment of the present invention will be described in detail below with reference to Figures 1 to 7. In the present invention, the fresh produce FT is mainly bananas, strawberries, grapes, blueberries, cherries, muscat grapes, loquats, figs, kiwi fruit, peaches, passion fruit, mangoes, etc., but also includes mandarins, apples, pears, persimmons, melons, etc., and vegetables such as tomatoes. The fresh produce FT may also include other fruits and vegetables, as well as seafood such as meat and fish.

[0013] First, the schematic configuration of a storage tray 100 according to this embodiment will be described with reference to FIG.

[0014] The storage tray 100 is made of resin (parts may be paper or metal) and includes a frame structure 102 and a resin sheet 108 held by the frame structure 102, as shown in FIG. 1. The storage tray 100 holds one or more fresh items FT with the resin sheet 108. The frame structure 102 has four legs (bases) 104 and a frame 106 supported by the legs 104. The resin sheet 108 has lower rigidity than the frame body 106, and when holding one or more fresh items FT, the portions where the alternating slits 108A are formed expand to form a net-decorated shape MD. At this time, the load acting on the resin sheet 108 due to the one or more fresh items FT is entirely supported by the frame body 106. The four legs 104 are located at the ends of the frame body 106, as shown in FIG. 1. In this embodiment, the fresh food FT is sized so that a plurality of fresh food FT can be held on the storage tray 100.

[0015] Next, the components of the storage tray 100 will be described in detail.

[0016] The frame constituent 102 is made of, for example, amorphous PET (polyethylene terephthalate) resin. Amorphous PET (polyethylene terephthalate) resin is highly transparent like glass, has a glossy finish, is shatter-resistant, and does not contain stabilizers or plasticizers (e.g., does not contain chlorine), making it safer than vinyl chloride resins and the like. In this embodiment, the legs 104 and frame body 106 are molded integrally with a thickness of less than a few millimeters. However, this is not a limitation, and the frame constituent may be molded from other resins, or the legs and frame body may be molded separately. In fact, the frame body and legs may each be molded from cardboard (including corrugated cardboard) or metal.

[0017] As shown in FIGS. 1 and 2(B), the legs 104 are cone-shaped with rounded tips. The legs 104 are disposed at the four corners of the frame body 106 (i.e., the legs 104 are disposed at the ends of the frame body 106). The height H of the legs 104 is equal to or less than the size of the fresh goods FT. The thickness of the resin sheet 108, the spacing of the notches 108A in the notch direction, the spacing of the notches 108A in the arrangement direction, and the length of the notches 108A are adjusted (for example, several mm to less than 10 cm) so that, when all the fresh goods FT to be held on the resin sheet 108 are held, the bottom surface of the resin sheet 108 does not bend at most to the position of the bottom ends of the legs 104 supporting the fresh goods FT. The legs 104 are provided at their upper portions with connecting recesses 104A. The connecting recesses 104A are shaped to follow the outline of the legs 104, so that when other storage trays 100 are stacked on top of one another, the legs 104 of the stacked storage trays 100 can fit into the connecting recesses 104A, as shown in Fig. 7. The configuration shown in Fig. 7 shows the state when a new storage tray 100 is shipped or delivered, or when used storage trays 100 are bundled together.

[0018] As shown in Fig. 2(B), the frame body 106 is supported by four legs 104. The frame body 106 is a rectangular frame with rounded corners when viewed from above, and as shown in Fig. 2(A), it has a protrusion 106A (for example, a protrusion of several millimeters) at the center of the lower long side, and a recess 106B (which may be a through hole in some cases) at the center of the upper long side that can fit into the protrusion 106A. At the same time, as shown in Fig. 2(A), it has a protrusion 106C (for example, a protrusion of several millimeters) at the center of the right short side, and a recess 106D (which may be a through hole in some cases) at the center of the left short side that can fit into the protrusion 106C (in other words, the storage tray 100 is configured to have a recess 106B (106D) and a protrusion 106A (106C) that can fit into each other, at symmetrical positions on the frame body 106). As a result, as shown in Figure 6, when one storage tray 100 holds fresh produce FT (for example, loquats or figs), another storage tray 100 can be placed opposite the one storage tray 100 and the recess 106B (106D) can be fitted into the protrusion 106A (106C).

[0019] Resin sheet 108 is supported on the upper part of frame body 106. Resin sheet 108 is, for example, a transparent polyurethane resin sheet with excellent elasticity and cushioning properties, and has a thickness of several tens to several hundreds of micrometers. Polyurethane resin is also used in building insulation, shoe soles, clothing, and the like. Alternatively, resin sheet 108 may be a transparent foamed resin sheet made of ethylene-vinyl acetate copolymer resin (EVA sheet). EVA sheets are lighter and softer than polyethylene, and their elasticity makes them resistant to external impacts. Furthermore, EVA sheets are highly resistant to water, do not deteriorate even when exposed to UV rays, and, because they do not contain chlorine, are considered to be environmentally friendly.

[0020] As shown in Fig. 3(A), the direction of the cuts 108A in the resin sheet 108 is the longitudinal direction (X direction) of the storage tray 100. Therefore, when a load is applied to the resin sheet 108, the resin sheet 108 significantly elongates, particularly in the direction (Y direction) perpendicular to the direction of the cuts 108A, and takes on a net-decorated shape MD, as shown in Fig. 3(B).

[0021] Here, the effect of the presence or absence of the decorative net pattern MD on the load (pressure) applied to the resin sheet 108 will be described with reference to FIGS. 4(A), (B), (C), and (D).

[0022] First, when the resin sheet 108 is bent by the load of the fresh product FT without the cut 108A, contraction forces Frx and Fry act in the X and Y directions to return the stretched resin sheet 108 to its original shape. Therefore, the combined forces Fx and Fy become compression forces (reaction forces) that act on the fresh product FT. At this time, as shown in Figures 4(A) and (B), both the compression forces Fx and Fy are considerable.

[0023] In contrast, when the notch 108A is provided along the X direction, as shown in Fig. 4(C), the compressive force Fx is the same as when there is no notch 108A. However, as shown in Fig. 4(D), the contraction force Fry in the Y direction can be made extremely small, and as a result, the resultant compressive force Fy can also be made extremely small.

[0024] That is, the presence of the notch 108A makes it possible to reduce the compressive force Fy on the short side from the Y direction, and therefore it is also possible to reduce the compressive force Fx on the long side from the X direction.

[0025] In this embodiment, for example, in order to hold five fresh produce (e.g., strawberries) FT, as shown in Fig. 5, five portions KR1, KR2, KR3, KR4, and KR5 in which five alternating cuts 108A are formed are provided at intervals on the resin sheet 108 of one storage tray 100 (that is, the portions KR1, KR2, KR3, KR4, and KR5 in which the alternating cuts 108A are formed are configured to be provided for each fresh produce FT at a distance that allows the fresh produce FT to remain out of contact with each other.) In addition, by wrapping the fresh produce FT placed on this storage tray 100, for example, by covering it with transparent cellophane, the fresh produce FT can be transported, displayed, and sold in a store.

[0026] As described above, in this embodiment, the resin sheet 108 has lower rigidity than the frame body 106, and when one or more fresh items FT are held in place, the portions where the alternating incisions 108A are formed stretch to form a net-decorated shape MD. Therefore, the resin sheet 108 holding the fresh items FT is extremely easy to stretch, making it possible to significantly reduce the compressive forces Fx and Fy applied to the fresh items FT. Furthermore, because the surface of the resin sheet 108 is smooth and adheres reasonably closely to the surface of the fresh items FT, the portions of the resin sheet 108 in contact with the fresh items FT also move as the fresh items FT move. This prevents the fresh items FT from rubbing against the resin sheet 108. At the same time, the resin sheet 108 does not absorb moisture from the fresh items FT, and by forming the net-decorated shape MD, it is possible to adequately ensure that the fresh items FT are able to breathe without losing their moisture.

[0027] The load (pressure) generated on the resin sheet 108 by one or more fresh items FT is supported entirely by the frame body 106. That is, even if the resin sheet 108 is bent by one or more fresh items FT, the resin sheet 108 is kept out of contact with anything other than the frame body 106. In other words, it is possible to prevent compressive forces Fx and Fy from being applied to the one or more fresh items FT from anything other than the resin sheet 108.

[0028] In this embodiment, the base portion is the leg portion 104 arranged at the end of the frame body 106. Therefore, the storage tray 100 can maintain good ventilation of the fresh goods FT through the decorative net shape MD of the resin sheet 108 that holds the fresh goods FT, and can prevent ethylene gas generated from the fresh goods FT from accumulating around the fresh goods FT. However, this is not limiting, and the base portion does not have to be the leg portion arranged at the end of the frame body.

[0029] Furthermore, in this embodiment, the upper part of the leg 104 is provided with a connecting recess 104A into which the leg 104 of another storage tray 100 can be fitted when the storage tray 100 is fully stacked on top of the other storage tray 100. Therefore, as shown in FIG. 7, it is possible to compactly store a large number of unused storage trays 100. Note that with this configuration, when two storage trays 100 are stacked, the fresh goods FT may be held by sandwiching the fresh goods FT between the two resin sheets 108. Note that this is not a limitation, and the connecting recess 104A into which the leg can be fitted does not have to be provided.

[0030] In this embodiment, the resin sheet 108 is transparent. Therefore, the state of the fresh food FT can be visually confirmed not only from above but also from below the storage tray 110. However, the present invention is not limited to this, and the resin sheet may be opaque.

[0031] In this embodiment, the resin sheet 108 is a polyurethane resin sheet. Polyurethane resin is widely used and easy to process, allowing the resin sheet 108 to be produced at low cost. However, the resin sheet is not limited to this, and may instead be an ethylene-vinyl acetate copolymer resin sheet (EVA sheet). EVA sheets are also chlorine-free materials, making them hygienic and safe. Furthermore, EVA sheets have a tensile modulus of elasticity that is one-tenth or less of that of PET resin, making it possible to minimize the compression rate applied to the fresh produce FT. Alternatively, the resin sheet may be made of another material, such as styrene resin.

[0032] Furthermore, in this embodiment, the portions KR1, KR2, KR3, KR4, and KR5 where the slits 108A are formed alternately are provided for each fresh item FT at a distance that allows the fresh items FT to remain out of contact with each other. Therefore, even if the fresh items FT are not positioned precisely, the portions without the slits 108A do not bend, and the fresh items FT move from those portions to the portions with the slits 108A, thereby automatically adjusting the positions of the fresh items FT. In other words, it is possible to reliably prevent the fresh items FT from coming into contact with each other. However, this is not limiting, and multiple fresh items FT may be held in a single storage tray with the slits evenly distributed in the resin sheet.

[0033] In this embodiment, the frame body 106 is provided with a recess 106B (106D) and a protrusion 106A (106C) that can be fitted together at symmetrical positions. When one storage tray 100 holds fresh products FT, another storage tray 100 can be placed opposite the first storage tray 100, and the recess 106B (106D) and the protrusion 106A (106C) can be fitted together. Therefore, the fresh products FT can be held in this manner to further prevent the effects of vibrations during delivery. In this case, even if the storage tray 100 is subjected to an impact that would turn it upside down, it is possible to prevent direct compressive force on the fresh products FT. However, this is not a limitation, and it is not necessarily required to adopt this configuration during delivery, etc.

[0034] In this embodiment, the direction of the cutouts 108A is the longitudinal direction (X direction) of the storage tray 100. Therefore, the net decoration shape MD facilitates extension in the lateral direction (Y direction) of the storage tray 100, while ensuring a reasonable extension in the longitudinal direction (X direction) of the storage tray 100. However, the cutouts are not limited to this, and may be in the lateral direction of the storage tray or in a diagonal direction that is neither the longitudinal direction nor the lateral direction.

[0035] Therefore, according to this embodiment, it is possible to provide a storage tray 100 that can prevent compression forces and scratches that are applied to the fresh food FT before it reaches the consumer, while ensuring appropriate breathability.

[0036] Although the present invention has been described using the first embodiment, the present invention is not limited to the first embodiment. In other words, it goes without saying that improvements and design changes are possible within the scope of the present invention.

[0037] For example, in the first embodiment, a single storage tray 100 holds multiple fresh items FT, but the present invention is not limited to this. For example, a second embodiment shown in FIGS. 8, 9(A), and 9(B) may be used. In this embodiment, in order to hold one fresh item FT per storage tray 200, slits 208A are provided throughout the resin sheet 208. For this reason, for example, in FIG. 8, two legs 204 of two storage trays 200 are connected together to support two fresh items FT. Also, in FIG. 9(A), one leg 204 of four storage trays 200 is connected to each other to support four fresh items FT. Also, in FIG. 9(B), one leg 204 of three storage trays 200 is connected to each other to support three fresh items FT.

[0038] As described above, in this embodiment, the upper part of the leg 204 is provided with a connecting recess 204A into which the leg 204 of another storage tray 200 can be fitted when the storage tray 200 is partially stacked on top of the other storage tray 200. Therefore, by connecting multiple storage trays 200 together, it is possible to create a single large storage tray that can simultaneously hold multiple relatively large fresh produce FT (e.g., peaches) that can only be held individually in a single storage tray 200. Furthermore, by combining the connections shown in FIGS. 9(A) and 9(B), it is possible to realize a display using storage trays 200 that will not shift position over time, for example, when sold in a store. Naturally, the connection of storage trays 200 is also possible with the storage tray 100 of the first embodiment, and the same effects as those of the second embodiment can be achieved.

[0039] In the above embodiment, the shape of the frame bodies 106, 206 is a rounded rectangle as shown in Fig. 10(A), but the present invention is not limited to this. For example, it may be a frame body 306 that is a rectangle with no rounded edges as shown in Fig. 10(B), a triangular frame body 406 as shown in Fig. 10(C), a circular frame body 506 as shown in Fig. 10(D), or another polygonal shape.

[0040] In the above embodiment, the legs are conical with rounded ends, but the present invention is not limited to this. The legs may be cylindrical and not tapered toward the bottom. In this case, the upper part of the legs may not have a connecting recess.

[0041] Furthermore, the leg 304 may be in the shape of a square pyramid or a square prism as shown in Fig. 11(A). When the leg 304 is a square pyramid, by providing a connecting recess in the upper part of the leg 304, it is possible to take the form shown in Fig. 7 or Fig. 8. In this case, when the leg 304 is a regular square pyramid, it is also possible to take the form shown in Fig. 9(A). When the leg 304 is a square prism that does not taper toward the bottom end, it is not necessary to provide a connecting recess in the upper part of the leg.

[0042] Also, there may be only two legs 404, as shown in Fig. 11(B). If the cross section of leg 404 is a triangular pyramid, a connecting recess may be provided at the top of leg 404, thereby making it possible to adopt the configuration shown in Fig. 7. In this case, if the cross section of leg 404 is a regular triangular pyramid, it is also possible to adopt the configuration shown in Fig. 8. If the cross section of leg 404 is a square that does not taper towards the bottom end, it is not necessary to provide a connecting recess at the top of the leg.

[0043] Furthermore, the leg 504 may be in the shape of a triangular pyramid or triangular prism as shown in Fig. 11(C). When the leg 504 is a triangular pyramid, by providing a connecting recess in the upper part of the leg 504, it is possible to adopt the shape shown in Fig. 7. In this case, when the leg 504 is a regular triangular pyramid, it is also possible to adopt the shape shown in Fig. 9(B). When the leg 504 is a triangular prism that does not taper toward the bottom end, it is not necessary to provide a connecting recess in the upper part of the leg.

[0044] 11(D), the base may be a box 604 without legs, with the upper end supporting the frame body. In this case, the base box 604 has a bottom surface 604A that covers the underside of the resin sheet, so that even if a compressive force is applied to the fresh goods FT from directly below the frame body, the bottom surface 604A can alleviate the compressive force. The base may be provided with one or more ventilation holes (not shown).

[0045] In the above embodiment, the incisions can be formed linearly in the longitudinal or lateral direction, but the present invention is not limited to this. For example, a third embodiment as shown in Fig. 12 may be used. In this embodiment, the incisions 708A are formed in the circumferential direction surrounding the fresh product FT.

[0046] In this embodiment, as shown in FIG. 12 , the storage tray 700 includes a substantially square frame body 706 when viewed from above. The frame body 706 has a substantially circular opening in the center. The opening is larger than the fresh goods FT. The legs 704 are integrally formed along the outer shape of the frame body 706. The resin sheet 708 is supported on the upper surface of the frame body 706, and has alternating notches 708A formed along the inside of the opening of the frame body 706 (notches may also be formed in the resin sheet outside the opening of the frame body). Therefore, when the resin sheet 708 supports the fresh goods FT, the portions where the alternating notches 708A are formed extend to form a net ornament shape. That is, in this embodiment, the net ornament shape MD is formed so as to surround the fresh goods FT. Furthermore, in this embodiment, a fresh goods support portion 708B is provided inside the notch 708A. Fresh product support portion 708B is a substantially circular portion of resin sheet 708 that does not have cuts 708A, and is provided to prevent resin sheet 708 from being excessively stretched.

[0047] In this manner, in this embodiment, the direction of the notches 708A is the circumferential direction surrounding the fresh product FT. Therefore, it is possible to appropriately hold relatively heavy fresh product FT such as apples, pears, peaches, and melons. In this embodiment, since the outer shape of the fresh product FT is close to a perfect circle when viewed from above, the notches 708A are provided in the circumferential direction of the perfect circle. However, if the outer shape of the fresh product FT is approximately an oval, the notches 708A may be provided in the circumferential direction of the oval. Also, it is not necessarily necessary to provide a fresh product support portion without a notch.

[0048] Furthermore, in the above-described embodiment, the storage trays can be arranged independently and in a plane, but the present invention is not limited to this. For example, the fourth embodiment shown in FIGS. 13, 14, 15(A), and 15(B) may be used. In the fourth embodiment, a frame structure 802 is formed inside a box body BX, such as a cardboard box, using plate-like members 802A and 802B that divide the interior into multiple sections. Then, by using this frame structure 802 to form a storage tray 800, it is possible to store many fresh products FT inside the box body 802. The plate-like members 802A and 802B can also be considered as members in which the base and frame body are integrated.

[0049] 13 and 14, the frame structure 802 is configured by combining, on a plane, four each of two plate-shaped members 802A and 802B made of, for example, cardboard (it does not necessarily have to be eight plate-shaped members in total, as long as it is configured by combining a plurality of plate-shaped members on a plane). As shown in Figures 15(A) and 15(B), the upper part of the plate-shaped member 802A (802B) is provided with three (one or more) convex portions 802AA (802BA), and the lower part of the plate-shaped member 802A (802B) is provided with concave portions 802AB (802BB) corresponding to the three convex portions 802AA (802BA). Since the resin sheet 808 is supported by the upper portion 806A (806B) of the plate-like member 802A (802B), the upper portion 806A (806B) can be considered as a frame body, and the portion 804A (804B) below the upper portion 806A (806B) can be considered as a base portion. That is, in this embodiment, the resin sheet 808 has through holes through which a total of 24 convex portions 802AA (802BA) shown in FIG. 14 pass, and is configured to be supported by the upper portions 806A, 806B of the plate-like members 802A, 802B. In FIG. 14, the frame structure 802 of the second stage B is stacked on the frame structure 802 of the first stage A, but in the storage tray 800, the resin sheet 808 is arranged on the frame structure 802 of the first stage A and the frame structure 802 of the second stage B. Reference numeral 802AC (802BC) denotes holding holes for inserting fingers to hold the frame structure 802, and also functions as a vent to promote ventilation of the fresh food FT. Reference numeral 802AD (802BD) denotes a connecting groove that connects to the connecting groove 802BD (802AD) of the plate-like member 802B (802A).

[0050] 15(A) (FIG. 15(B)), the width W1 (W4) of the plate-like member 802A (802B) is slightly narrower than the width of the inside of the box body BX (the resulting gap is preferably less than the thickness of the plate-like member 802A (802B)). Furthermore, the widths W2, W3 (W5, W6) are preferably wider than the thickness of the hand of an operator who stores the frame structure 802 in the box body BX (that is, in this embodiment, as shown in FIG. 14, when a plurality of frame structures 802 are stacked so that the recessed portions 802AB (802BB) and the protruding portions 802AA (802BA) fit together, the box body BX has an inner shape that prevents the frame structures 802 from shifting until the frame structures 802 lose their position).

[0051] As described above, in this embodiment, the frame structure 802 is configured by combining, on a plane, a plurality of plate-like members 802A, 802B, each having a base portion and a frame body integrated therein. Therefore, compared to storing a plurality of independent storage trays in a plane in the box body BX, the storage tray 800 can reduce the area occupied by the frame body portion in a planar view, so that fresh products FT can be packed more densely than before, and more fresh products FT can be stored in the box body BX. However, this is not a limitation, and the storage trays do not necessarily have to be stored in the box body BX.

[0052] In this embodiment, the upper portion of the plate-shaped member 802A (802B) is provided with three (one or more) convex portions 802AA (802BA), and the lower portion of the plate-shaped member 802A (802B) is provided with concave portions 802AB (802BB) corresponding to the three convex portions 802AA (802BA). The resin sheet 808 has through-holes through which a total of 24 convex portions 802AA, 802BA pass, and is supported by upper portions 806A, 806B of the plate-shaped members 802A, 802B. Therefore, by stacking a plurality of frame structures 802 so that the concave portions 802AB, 802BB fit into the convex portions 802AA, 802BA (FIG. 14 shows two layers, but more layers (e.g., ten or more layers) are possible), the storage tray 800 can store many fresh products FT densely in the box body BX without them touching each other. However, the storage tray does not necessarily have to be stored in the box body BX.

[0053] Furthermore, in this embodiment, the box body BX has an internal shape that prevents the frame structures 802 from shifting until the frame structures 802 lose their position when multiple frame structures 802 are stacked together so that the recessed portions 802AB, 802BB fit together with the protruding portions 802AA, 802BA. This allows many fresh goods FT to be stored compactly in the box body BX while being easily transported, and prevents the fresh goods FT from being compressed or damaged even if a large impact is applied to the box body BX.
