Description

Transport container {TRANSPORT CONTAINER}

The present invention relates to a transport container used for transporting an article.

In order to maintain the quality of the product and provide it to the market, it is necessary to protect the product from impact during transportation. For example, strawberries with relatively soft skin, cosmetics made from compressed powdery raw materials, etc. may be damaged by friction with the transport container during transportation, and special measures are required.

As a transport container for protecting a fruit from impact or the like, Patent Document 1 describes a storage tray surrounding a fruit with a thin film sheet. The sheet is formed of a thermoplastic resin, and is said to be rich in elasticity and flexibility. A plurality of protrusions projecting upward are formed on the bottom plate forming the bottom of the receiving tray. When the sheet is supported from below by the plurality of protrusions, the sheet is displaced downward between the protrusions to form a plurality of recesses.

When one fruit is received in each recess, the fruit is surrounded by a sheet forming the recess, and is kept independent of each other. As a result, it is said that the fruits are protected from impact during transportation and the likelihood of damage can be reduced.

Japanese Patent Application Publication No. 2011-102152

By the way, when the transport vehicle travels on the minute unevenness of the road surface, a vibration with a relatively high frequency occurs in the vehicle body. Even when the transport vehicle is stationary or when transported by a ship, the same vibration may be generated by driving the engine. This vibration is also transmitted to the transport container.

The sheet of the accommodating tray described in patent document 1 is supported by projections at four points around each recess. For this reason, the distance between the projections is relatively short, and the natural frequency of the concave portion formed between the projections is relatively high. In various transportation tests conducted by the inventors of the present invention, when vibration with a relatively high frequency is transmitted to the concave portion through the protrusion, the phenomenon that the article contained in the concave portion resonates has been developed. The resonant article vibrates little by little within the concave portion or rotates irregularly. As a result, repeated friction between the article and the sheet occurred, resulting in a problem that the article was damaged.

The present invention has been made in view of such problems, and its object is to provide a transport container capable of reducing damage to an article.

In order to solve the above-mentioned problem, the first transport container according to the present invention is a transport container used for transporting an article, and has a body bottom portion and a body side wall portion extending upward from a peripheral edge of the body bottom portion, It is provided with a container body which forms an accommodation space surrounded by the side wall portion above the bottom of the main body, and a middle container disposed in the accommodation space. The middle container has a top plate on which an article receiving portion is formed and a middle container portion extending downward from an outer portion of the top plate among the article receiving portions, and is supported from the bottom by the main body bottom portion only by the middle container portion. The container body has a body portion protruding downward from the body bottom portion. The main body portion does not overlap with the middle container portion in plan view, and is disposed closer to the center portion of the body bottom portion than the middle container portion.

According to the said structure, the container main body is supported by the bottom surface of a corrugated cardboard box, etc. in each body part, while supporting the middle container part of a heavy container during transport of an article. The main body parts do not overlap with the middle container parts when viewed in plan. For this reason, the part between the main body part and the middle container part among the bottom parts of the main body was broken by the force received from both sides. By increasing the distance between the main body parts and the middle container parts, the natural frequency of the site can be made low. As a result, it is possible to suppress transmission of vibrations having a relatively high frequency that causes resonance of the article from the main body parts to the middle container parts.

In addition, the main body portion is disposed closer to the center of the body bottom portion than the middle container portion when viewed in plan. Therefore, it becomes possible to make the container body compact in comparison with the case where the main body parts are disposed outside the bottom of the main body than the middle container parts.

That is, according to the said structure, although it is a compact structure, it becomes possible to reduce damage to an article.

The article accommodating portion is formed concave downward to form a plurality of concave portions for accommodating the article, the concave portion is a concave bottom surface, and an erected side connected to one end of the concave bottom surface and extending toward the top plate, It has an inclined side surface connected to the other end of the bottom surface of the concave portion and extending toward the top plate, and the angle formed by the inclined side surface and the top plate may be smaller than the angle formed by the standing side and the top plate.

In general, the appearance of strawberries, loquats, figs, etc., is the largest in the vicinity of the faucet (also referred to as the "pet") and gradually decreases as it moves away from the faucet. Therefore, the center of gravity of these fruits is located near the apex. When the center of gravity of the fruit moves during transportation, resonance of the fruit occurs.

According to the above structure, when fruits such as strawberries, loquat, and figs are accommodated in the concave portion, the fruit is surrounded by the bottom surface of the concave portion, the standing side, and the inclined side. The bottom surface of the concave portion supports the fruit from below, and the standing side supports the portion near the apex of the fruit from the side. In addition, the inclined side supports the portion where the outer shape of the fruit gradually decreases along the outer shape. Thereby, it is possible to support the fruit in a state where the center of gravity of the fruit is arranged near the bottom of the recess while distributing the load received from the recess by contacting the outer surface of the fruit in a wide range. As a result, the movement of the center of gravity of the fruit can be suppressed, and even when vibration with a high frequency is transmitted from the bottom of the main body to the concave portion of the article accommodating portion, it becomes possible to suppress resonance of the fruit and damage to the epidermis accompanying it.

In the supported portion, each middle container portion extending downward from the top plate is formed. The heavy container may be supported only by the parts of the heavy container.

Each of the heavy container parts is formed in the supported portion located outside the article receiving portion in the top plate. Therefore, according to the said structure, it can be comprised so that a top plate may be supported by the upper end of each part of the heavy container which was largely separated. Thereby, the natural frequency of the article accommodating part which vibrates between each part of the said middle container can be made comparatively low. As a result, even when vibration with high frequency is transmitted from the bottom of the main body to the concave portion of the article accommodating portion through the middle container portion, it becomes possible to suppress resonance of the article and damage accompanying it.

Moreover, the 2nd transport container which concerns on this invention has a main body bottom part, and the main body side wall part extended upward from the circumferential edge of a main body bottom part, The container body which forms the accommodation space surrounded by the main body side wall part above the main body bottom part. And, it is provided with a middle container having a top plate disposed in the receiving space at a distance from the main body. The top plate has a fruit accommodating portion and a supported portion formed outside the fruit accommodating portion. The fruit receiving portion is formed concave downward to form a plurality of concave portions through which the fruit is accommodated. The concave portion has a concave bottom surface, an erect side surface connected to one end of the concave bottom surface and extending toward the top plate, and an inclined side surface connected to the other end of the concave bottom surface and extending toward the top plate. The angle formed by the inclined side and the top plate is smaller than the angle formed by the standing side and the top plate.

According to the above structure, when fruits such as strawberries, loquat, and figs are accommodated in the concave portion, the fruit is surrounded by the bottom surface of the concave portion, the standing side, and the inclined side. The bottom surface of the concave portion supports the fruit from below, and the standing side supports the portion near the apex of the fruit from the side. In addition, the inclined side supports the portion where the outer shape of the fruit gradually decreases along the outer shape. Thereby, the fruit can be supported in a state in which the center of gravity of the fruit is arranged near the bottom of the recess while distributing the load received from the recess by contacting the outer surface of the fruit in a wide range. As a result, the movement of the center of gravity of the fruit is suppressed, and even when vibration with a high frequency is transmitted from the bottom of the main body to the concave portion of the fruit receiving portion, it becomes possible to suppress resonance of the fruit and damage to the epidermis accompanying it.

In the supported portion, each middle container portion extending downward from the top plate is formed. The heavy container may be supported only by the parts of the heavy container.

Each of the heavy container parts is formed on a supported portion located outside the article receiving portion of the top plate. Therefore, according to the said structure, it can be comprised so that a top plate may be supported by the upper end of each part of the heavy container which was largely separated. Thereby, the natural frequency of the article accommodating part which vibrates between each part of the said middle container can be made comparatively low. As a result, even when vibration with high frequency is transmitted from the bottom of the main body to the concave portion of the article accommodating portion through the middle container portion, it becomes possible to suppress resonance of the article and damage accompanying it.

In addition, the third transport container according to the present invention has a main body bottom portion, and a main body side wall portion extending upward from a circumferential edge of the main body bottom portion, and forms a receiving space surrounded by the main body side wall portion above the main body bottom portion. And, it is provided with a middle container having a top plate disposed in the receiving space at a distance from the main body. The top plate has a fruit accommodating portion and a supported portion formed outside the fruit accommodating portion. The fruit receiving portion is formed concave downward to form a plurality of concave portions through which the fruit is accommodated. In the supported portion, each middle container portion extending downward from the top plate is formed. The medium container is supported only by the parts of the medium container.

The medium container is supported only by the parts of the medium container. Each of the heavy container portions is formed in the supported portion located outside the fruit receiving portion in the top plate. Therefore, according to the said structure, it can be comprised so that a top plate may be supported by the upper end of each part of the heavy container which was largely separated. Thereby, the natural frequency of the fruit accommodating part which vibrates between each part of the said middle container can be made comparatively low. As a result, even when vibration with high frequency is transmitted from the bottom of the main body to the concave portion of the fruit receiving portion through each of the middle container portions, it becomes possible to suppress resonance of the fruit and damage to the epidermis accompanying it.

However, if the bottom of the main body is flat, when the transport container is accommodated in a cardboard box or the like, there is a fear that the contact range between the bottom of the main body and the bottom surface of the cardboard box is not constant. Specifically, if the bottom surface of the corrugated cardboard box is distorted, the bottom portion of the main body contacts the bottom surface of the corrugated cardboard box only on a part of the omission. As described above, when the contact range between the bottom of the main body and the bottom surface of the corrugated cardboard box is not constant, the transmission path of vibration from the corrugated cardboard box to the bottom of the main body becomes irregular, and there is a fear that resonance suppression of fruit cannot be adequately suppressed. .

Therefore, in the container body, a plurality of body parts protruding downward are formed at the bottom of the body, and the plurality of body parts may be separated from each other.

According to this configuration, even when the bottom surface of the corrugated cardboard box is distorted, the bottom of the main body can be deformed between each of the plurality of main body parts to easily follow the distortion. As a result, it is possible to stably contact each of the plurality of main body parts with a bottom surface such as corrugated cardboard, thereby making it possible to make the contact range between the bottom of the main body and the bottom surface of the cardboard box constant.

The transport container is provided with a sheet-like cushioning material between the container body and the heavy container, and each of the heavy container parts may be supported by the bottom of the body through the cushioning material.

According to this configuration, it becomes possible to adjust the frequency of the vibration transmitted from the container body to the middle container with a cushioning material. By setting the resonant frequency of the cushioning material to be lower than the resonant frequency of the heavy container, it becomes possible to suppress the resonance of the fruit caused by the vibration and the damage to the epidermis accompanying it.

The edge portion of the cushioning material may be bent, and the edge portion may be disposed between the main body side wall portion and each of the middle container portions.

According to this configuration, even when the heavy container moves within the accommodation space during transportation of the transport container, collision between the main body side wall part and each of the heavy container parts can be alleviated by the edge portion of the cushioning material. As a result, it is possible to alleviate the impact on the fruit and suppress damage to the skin of the fruit.

However, in the corner portion of the accommodation space, the edge portion of the curved cushioning material may overlap. When each of the heavy container parts of the heavy container is fixed to the side wall part of the main body through the edge portion of the overlapped cushioning material, unnecessary vibration is transmitted from the container body to the heavy container, and there is a fear that the resonance of the fruit cannot be suppressed.

Therefore, the height of the edge portion of the cushioning material may be 1/2 or less of the side wall portion of the main body.

According to this configuration, even if the edge portion of the bent buffer material overlaps at the corner portion of the accommodation space, it is possible to easily prevent the middle container portion of the middle container from being fixed to the side wall portion of the body through the edge portion of the buffer material.

The middle container portion may be formed over the entire circumferential edge of the top plate.

According to this configuration, by supporting the entire circumferential edge of the top plate by the middle container portion, excessive bending of the top plate downward can be suppressed. As a result, it is possible to suppress that the concave portion accommodating the article is in contact with the bottom portion of the body, or vibration is transmitted directly to the concave portion from the bottom portion of the body.

The middle container parts may be inclined from the upper end to the lower end so as to extend outward from the top plate.

According to this configuration, when the medium container receives an external force, it is possible to elastically deform the parts of the medium container so that they fall inward. As a result, even when the bottom portion of the main body vibrates at a relatively high frequency, it is possible to reduce the transmission of vibration by elastic deformation of each portion of the middle container, thereby suppressing resonance of the article and damage to the article accompanying it.

The middle container portion may have an inflection portion in which the normal direction of the outer surface changes between the upper end and the lower end.

According to this configuration, when the heavy container receives external force, each of the heavy container parts can cause elastic deformation starting from the inflection portion. As a result, even when the bottom portion of the main body vibrates at a relatively high frequency, it is possible to reduce the transmission of vibration by elastic deformation of each portion of the middle container, thereby suppressing resonance of the article and damage to the article accompanying it.

ADVANTAGE OF THE INVENTION According to this invention, the transport container which can reduce the damage of an article can be provided.

<First Embodiment>

First, with reference to FIGS. 1 to 4, the configuration of the transport container 1 according to the first embodiment of the present invention will be described. 1 is a perspective view showing the transport container 1. 2 is an exploded view showing the transport container 1. 3 is a plan view showing the transport container 1. FIG. 4 is a cross-sectional view showing a section IV-IV in FIG. 3, and a part of the section is omitted. For ease of understanding, FIG. 4 shows only the IV-IV cross section of the transport container 1. In addition, in FIG. 2 and FIG. 3, the main body part 211 of the container main body 2 is shown with the broken line.

The transport container 1 is a container used for transport while accommodating a plurality of strawberries. Moreover, after transportation, the transport container 1 can be displayed in front of a store in the state which accommodated the strawberry. Strawberry is an example of a preferable article, and the transport container 1 may contain loquat, figs, and the like having the same shape as strawberry.

The transport container 1 is provided with a container body 2, a middle container 3, and a cover member not shown.

The container body 2 is formed of a thermoplastic resin such as polyethylene terephthalate, polystyrene, and polypropylene. 2, the container body 2 has a body bottom portion 21 and a body side wall portion 22. The main body bottom portion 21 is a substantially flat-shaped portion, and its outer shape shows a rectangular shape when viewed from a plane. The body side wall portion 22 extends upward from the circumferential edge of the body bottom portion 21. The main body side wall portion 22 is formed over the entire circumferential edge of the main body bottom portion 21 and exhibits a closed annular shape. The main body bottom portion 21 and the main body side wall portion 22 are integrally formed, and the thickness thereof is both constant from about 0.20 mm to about 0.50 mm.

The container body 2 forms the accommodation space 20. The accommodation space 20 is a space which is divided by the main body bottom portion 21 and the main body side wall portion 22 and is opened upward. Moreover, as shown in FIG. 2, four main body parts 211 are formed in the container main body 2. As shown in FIG. The main body part 211 is formed integrally with the main body bottom part 21 and protrudes downward from the main body bottom part 21.

The middle container 3 is formed of a thermoplastic resin such as polyethylene terephthalate, polystyrene, and polypropylene. The thickness of the middle container 3 is about 0.1 mm to 0.5 mm, and it has flexibility. The heavy container 3 has a top plate 31. The top plate 31 is a substantially flat portion, and its outer shape shows a rectangular shape slightly smaller than the body bottom portion 21 of the container body 2 in plan view. 2 and 3, the top plate 31 has a fruit receiving portion 311 and a supported portion 312.

The fruit accommodating part 311 is an example of an article accommodating part, and is a part near the inside of the top plate 31. A recess 32 formed concave downward from the top plate 31 is formed in the fruit accommodation portion 311. Four recesses 32 are arranged in a straight line at intervals of four from the top plate 31 in the short side direction and five in the long side direction. For example, in the case of the transport container 1 having a dimension in the short side direction of 150 mm and a dimension in the long side direction of 3 mm, the number of the recesses 32 is preferably 3 to 20.

As shown in Fig. 4, the concave portion 32 has a concave portion bottom surface 32a, a standing side surface 32b, and an inclined side surface 32c.

The recess bottom surface 32a is a lower surface of the recess 32. The recess bottom surface 32a is curved so as to protrude downward.

The standing side surface 32b is a surface whose lower end is connected to one end of the bottom surface 32a of the recess and extends toward the top plate 31. The upper end of the standing side 32b is connected to the top plate 31. The standing side 32b extends to form the angle θ1 with the top plate 31.

The inclined side surface 32c is a surface whose lower end is connected to the other end of the bottom surface 32a of the recess and extends toward the top plate 31. The upper end of the inclined side surface 32c is connected to the top plate 31. The inclined side surface 32c is arranged to face the standing side surface 32b in the horizontal direction. The inclined side surface 32c extends to form the angle θ2 with the top plate 31. The angle θ2 is smaller than the angle θ1 described above.

The supported portion 312 is a portion outside the fruit receiving portion 311 of the top plate 31. The supported portion 312 surrounds the fruit receiving portion 311 and is formed over the entire circumferential edge of the top plate 31.

In the supported portion 312, a middle container leg portion 34 extending downward from the top plate 31 is formed. The middle container leg 34 and the top plate 31 are integrally formed. The middle container leg 34 is inclined to extend outward from the top plate 31 from the top 34a side connected to the top plate 31 to the bottom 34b side.

Moreover, as one aspect, the middle container leg portion 34 may have two inflection portions 34c between the upper end 34a and the lower end 34b. In the inflection portion 34c, the normal direction of the outer surface is different from the normal direction of other parts of the outer surface. The bent portion 34c is formed so as to extend linearly along each of the short side and long side of the top plate 31, whereby the middle container portion 34 has a stepped shape.

The heavy container 3 thus formed is disposed in the accommodation space 20 of the container body 2. The heavy container 3 is not restrained with respect to the container body 2, but is supported by contacting the upper surface of the body bottom portion 21 only at the lower end 34b of the heavy container leg portion 34. By not binding the heavy container 3 to the container body 2, transmission of vibrations from the container body 2 to the heavy container 3 can be reduced.

In addition, a gap is formed between the main body side wall portion 22 of the container body 2 and the middle container leg portion 34. It is preferable that the size of the gap is about 0.1 mm to 5 mm. By setting it as such a dimension, the movement of the heavy container 3 in the accommodation space 20 at the time of transportation can be made small, and as a result, the impact on the strawberry S accompanying the movement of the heavy container 3 Can be suppressed.

Since the middle container 3 is disposed in the accommodation space 20, the top plate 31 is disposed at a distance from the main body bottom portion 21. In addition, a gap of about 3 mm is formed between the bottom surface 32a of the concave portion 32 and the top surface of the body bottom portion 21.

As shown in FIG. 3, the main body parts 211 of the container body 2 are arranged so as not to overlap with the middle container parts 34 in plan view. In addition, the main body part 211 is disposed closer to the center of the main body bottom part 21 than the middle container part 34.

The strawberry S accommodated by the transport container 1 is accommodated in the recess 32 of the middle container 3. When the strawberry S is accommodated in the concave portion 32, the lower surface thereof is in contact with the bottom surface 32a of the concave portion and is supported from below. Moreover, the side surface of the strawberry S side on the top S1 side is supported from the side by the standing side surface 32b. In addition, the portion S2 of which the outer shape of the strawberry S gradually decreases is supported in contact with the inclined side surface 32c. In short, the concave portion 32 has a shape that conforms to the outer shape of the strawberry S so that the strawberry S accommodated can be stably maintained. The middle container 3 is given a predetermined rigidity so that even when the strawberry S is accommodated in the concave portion 32, the concave portion bottom surface 32a does not come into contact with the upper surface of the body bottom portion 21. .

The container body 2 and the middle container 3 are in a state where the strawberry S is accommodated in the concave portion 32 and are covered by a cover member (not shown). The lid member is fixed so as to be freely detachable from the upper end of the side wall portion 22 of the container body 2. The cover member is formed of a thermoplastic resin such as polyethylene terephthalate, polystyrene, and polypropylene. From the viewpoint of visibility and beauty, it is preferable that the lid member is transparent. When the lid member is transparent, even if the strawberry S is displayed in front of the store while being accommodated in the transport container 1, the consumer can recognize the state of the strawberry S over the lid member.

From the viewpoint of fitting and sealing with the container body 2, the lid member is preferably a molded article obtained by vacuum forming, pressure forming, or the like using a single sheet or film. During the molding, the sheet or film is softened by heating to adhere to the mold. Moreover, it is preferable that it is a plate-shaped flexible film from a viewpoint which protects the strawberry S from the impact at the time of transportation.

From the viewpoint of protecting the strawberry S from loading efficiency and impact during transportation, the lid member is preferably an overlap packaging using a single-plate flexible sheet film, a pillow shrink packaging, or a top seal packaging. When packaging, the entire container is covered with a sheet or film and sealed, which is preferable from the viewpoint of preventing the ingress of foreign matter from the outside. Moreover, since the film is adhered to the container when the film is shrunk by heat at the time of packaging, it is preferable from the viewpoint of aesthetic properties.

As the material of the lid member, a single substance or a mixture of polyethylene, polypropylene, ethylene-vinyl acetic acid copolymer, polystyrene, polyvinyl chloride, polyvinylidene chloride, etc. is preferable. In the case of a film or sheet, a monolayer may be used, It may be a laminate.

Next, referring to Figs. 4 and 5, the operational effects of the transport container 1 will be described. 5 is an explanatory diagram for explaining a deformation of the transport container 1. For ease of understanding, FIG. 5 shows only the IV-IV cross section of the transport container 1.

During transportation of the strawberry S, the container body 2 supports the middle container leg 34 of the middle container 3. As shown by arrow F1 in FIG. 4, the container body 2 receives downward force from each of the middle container parts 34. In addition, the container body 2 is supported by the bottom surface CB of the corrugated cardboard box in the main body portion 211. The container main body 2 receives upward force from the bottom surface CB of the corrugated cardboard box in the main body 211, as indicated by arrow F2 in FIG. 4.

When the transport container 1 does not receive external force, such as during non-transportation, as shown in Fig. 5, the body bottom portion 21 is disposed at the position indicated by the solid line 21A.

On the other hand, when the transport container 1 receives an external force, such as during transport, vibration may occur in the bottom portion 21 of the main body. At this time, the main body bottom part 21 is deformed to bend between the main body part 211 and the middle container part 34, as indicated by the broken line 21B. In addition, the broken line 21B is shown with extreme displacement for understanding.

As described above, since the main body bottom part 21 is deformed between the main body part 211 and the middle container part 34 which are largely separated, the natural frequency thereof is relatively low. As a result, even when vibration with a relatively high frequency is transmitted from the main body portion 211 to the concave portion 32 of the fruit receiving portion 311 through the middle container portion 34, the resonance of the strawberry S and accompanying it It becomes possible to suppress damage to the epidermis.

Moreover, the main body part 211 is arranged closer to the center of the main body bottom part 21 than the middle container part 34 when viewed in plan. Therefore, it becomes possible to make the container body 2 compact in comparison with the case where the main body part 211 is disposed outside the main body bottom part 21 rather than the middle container part 34.

4, when the strawberry S is accommodated in the recess 32, the strawberry S is surrounded by the bottom surface 32a, the standing side 32b, and the inclined side 32c of the recess. . The recessed bottom surface 32a supports the strawberry S from below, and the standing side 32b supports the area near the apex S1 of the strawberry S from the side. In addition, the inclined side surface 32c supports the portion S2 in which the outer shape of the strawberry S gradually decreases along the outer shape.

Thereby, in a wide range, the center of gravity (G) of the strawberry (S) is near the lower side of the concave portion (32) while dispersing the load received from the concave portion (32) by contacting the outer surface of the strawberry (S). Strawberries (S) can be supported in a state placed in the. As a result, the movement of the center of gravity G of the strawberry S is suppressed, and even when vibration with a high frequency is transmitted from the body bottom portion 21 to the concave portion 32 of the fruit receiving portion 311, the strawberry It becomes possible to suppress resonance of (S) and damage to the epidermis accompanying it.

In the supported portion 312, a middle container leg portion 34 extending downward from the top plate 31 is formed. The heavy container 3 is supported from below only by the heavy container corners 34.

The middle container corner portion 34 is formed in the supported portion 312 located outside the fruit receiving portion 311 in the top plate 31. Therefore, according to this structure, the top plate 31 is supported by the upper end 34a of the middle container part 34 which is largely separated.

When the transport container 1 does not receive external force, such as during non-transportation, as shown in Fig. 5, the top plate 31 is disposed at the position indicated by the broken line 31A. That is, the top plate 31 is slightly downward due to the weight of the strawberry S (see Fig. 4) accommodated in the recess 32, but is generally in a substantially horizontal state with the body bottom 21.

On the other hand, when the transport container 1 receives an external force, such as during transport, vibration may occur in the top plate 31. At this time, the top plate 31 is deformed in a mode in which the upper end 34a of each middle container portion 34 is set to a point (支點), as indicated by the broken line 31B. In addition, the broken line 31B is shown in extreme displacement for understanding.

As described above, since the top plate 31 is deformed with the upper end 34a of each of the middle container portions 34 largely separated as a point, the natural frequency thereof is relatively low. As a result, even when vibration with a relatively high frequency is transmitted from the bottom portion 21 of the main body to the concave portion 32 of the fruit receiving portion 311 through the middle container portion 34, the resonance of the strawberry S and the resonance It becomes possible to suppress the accompanying epidermal damage.

The middle container leg portion 34 is formed over the entire circumferential edge of the top plate 31.

According to this configuration, by supporting the entire circumferential edge of the top plate 31 by the middle container leg portion 34, excessive bending of the top plate 31 downward can be suppressed. As a result, it is suppressed that the concave portion 32 accommodating the strawberry S comes into contact with the main body bottom portion 21, whereby vibration is transmitted directly from the main body bottom portion 21 to the concave portion 32. can do.

The middle container leg 34 is inclined to extend outward from the top plate 31 from the upper end 34a side to the lower end 34b side.

According to this structure, when the heavy container 3 receives external force, as indicated by the arrow M, it becomes possible to elastically deform the heavy container leg 34 so that it falls inward. As a result, even when the main body bottom portion 21 vibrates at a relatively high frequency, the transmission of vibration is reduced by the elastic deformation of the container portion 34 of the middle container, and the resonance of the strawberry S and the damage to the epidermis accompanying it. It becomes possible to suppress.

The middle container section 34 has an inflection section 34c whose normal direction of the outer surface changes between the upper end 34a and the lower end 34b.

According to this configuration, when the heavy container 3 receives external force, each of the heavy container parts 34 can cause elastic deformation starting from the inflection part 34c. As a result, even when the main body bottom portion 21 vibrates at a relatively high frequency, the transmission of vibration is reduced by the elastic deformation of the container portion 34 of the middle container, and the resonance of the strawberry S and the damage to the epidermis accompanying it. It becomes possible to suppress.

<Second Embodiment>

Next, the structure of the transport container 1A according to the second embodiment will be described with reference to FIGS. 6 to 9. The transport container 1A according to the present embodiment is a modification of the configuration of the container body 2 of the transport container 1 according to the first embodiment, and the other configurations are substantially the same as those of the first embodiment. . For this reason, the description will be mainly centered on different configurations, and the same reference numerals will be used for overlapping configurations, and detailed descriptions will be omitted.

6 is a perspective view showing the transport container 1A. 7 is an exploded view showing the transport container 1A. 8 is a plan view showing the transport container 1A. FIG. 9 is a cross-sectional view showing a cross section of IX-IX in FIG. 8, and a part of the cross section is omitted.

The transport container 1A includes a container body 2A, a middle container 3, and a cover member (not shown). Since the heavy container 3 and the lid member are substantially the same as the heavy container 3 and the lid member in the first embodiment, detailed description is omitted.

The container body 2A is formed of a thermoplastic resin such as polyethylene terephthalate, polystyrene, and polypropylene, similar to the container body 2 in the first embodiment, and includes a storage space 20 and a body bottom It has (21) and a main body side wall part (22). On the other hand, in the container main body 2A in the present embodiment, the main body portion protruding downward from the main body bottom portion 21 is not formed, and as shown in Fig. 7, the main body bottom portion 21 is flat.

The heavy container 3 is disposed in the accommodation space 20 of the container body 2A. The heavy container 3 is not restrained with respect to the container body 2A, but is supported by contacting the upper surface of the body bottom portion 21 only at the lower end 34b of the heavy container leg portion 34. By not binding the heavy container 3 to the container body 2A, transmission of vibrations from the container body 2A to the heavy container 3 can be reduced.

In addition, a gap is formed between the main body side wall portion 22 of the container body 2A and the middle container leg portion 34. It is preferable that the size of the gap is about 0.1 mm to 5 mm. By setting it as such a dimension, the movement of the heavy container 3 in the accommodation space 20 at the time of transportation can be made small, and as a result, the impact on the strawberry S accompanying the movement of the heavy container 3 Can be suppressed.

Since the middle container 3 is disposed in the accommodation space 20, the top plate 31 is disposed at a distance from the main body bottom portion 21. In addition, a gap of about 3 mm is formed between the bottom surface 32a of the concave portion 32 and the top surface of the body bottom portion 21.

The strawberry S accommodated by the transport container 1A is accommodated in the concave portion 32 of the middle container 3. When the strawberry S is accommodated in the concave portion 32, the lower surface thereof is in contact with the bottom surface 32a of the concave portion and is supported from below. Moreover, the side surface of the strawberry S side on the top S1 side is supported from the side by the standing side surface 32b. In addition, the portion S2 in which the outer shape of the strawberry S gradually decreases is supported in contact with the inclined side surface 32c. In short, the concave portion 32 has a shape that conforms to the outer shape of the strawberry S so that the strawberry S accommodated can be stably maintained. The middle container 3 is given a predetermined rigidity so that even when the strawberry S is accommodated in the concave portion 32, the concave portion bottom surface 32a does not come into contact with the upper surface of the body bottom portion 21. . The container body 2A and the middle container 3 are covered with a cover member (not shown) in the state where the strawberry S is accommodated in the recess 32.

Next, the operational effects of the transport container 1A will be described with reference to FIGS. 9 and 10. 10 is an explanatory diagram for explaining a deformation of the transport container 1A. For ease of understanding, FIG. 10 shows only the IX-IX cross section of the transport container 1A.

The heavy container 3 is supported by contacting the bottom portion 21 of the main body only by the heavy container corners 34. The middle container corner portion 34 is formed in the supported portion 312 located outside the fruit receiving portion 311 in the top plate 31. Therefore, according to this structure, the top plate 31 is supported by the upper end 34a of the middle container part 34 which is largely separated.

When the transport container 1A is not subjected to an external force, such as during non-transportation, as shown in Fig. 10, the top plate 31 is disposed at the position indicated by the broken line 31A. That is, the top plate 31 is slightly downward due to the weight of the strawberry S (see Fig. 9) accommodated in the recess 32, but is generally in a substantially horizontal state with the body bottom 21.

On the other hand, when the transport container 1A receives an external force, such as during transport, vibration may occur in the top plate 31. At this time, as shown by the broken line 31B, the top plate 31 is deformed in a mode in which the upper end 34a of each middle container portion 34 is a point. In addition, the broken line 31B is shown in extreme displacement for understanding.

As described above, since the top plate 31 is deformed with the upper end 34a of each of the middle container portions 34 largely separated as a point, the natural frequency thereof is relatively low. As a result, even when vibration with a relatively high frequency is transmitted from the bottom portion 21 of the main body to the concave portion 32 of the fruit receiving portion 311 through the middle container portion 34, the resonance of the strawberry S and the resonance It becomes possible to suppress the accompanying epidermal damage.

According to this structure, when the heavy container 3 receives external force, as indicated by the arrow M, it becomes possible to elastically deform the heavy container leg 34 so that it falls inward. As a result, even when the main body bottom portion 21 vibrates at a relatively high frequency, the transmission of vibration is reduced by the elastic deformation of the container portion 34 of the middle container, and the resonance of the strawberry S and the damage to the epidermis accompanying it. It becomes possible to suppress.

<Third embodiment>

Next, the configuration of the transport container 1B according to the third embodiment will be described with reference to FIGS. 11 to 13. 11 is an exploded view showing the transport container 1B. 12 is a plan view showing the transport container 1B. 13 is a cross-sectional view showing a cross-section XIII-XIII of FIG. 12, and a part of the cross-section is omitted.

As in the second embodiment, the transport container 1B is a container that accommodates a plurality of strawberries and is used for transport. The configuration of the transport container 1B is different from the second embodiment in that the air packing 4 is provided and the main body portion 211 is formed on the container body 2B. In the configuration of the transport container 1B, the same reference numerals are given to the same components as those in the second embodiment, and description thereof is omitted as appropriate.

The air packing 4 is formed of a resin material such as polyethylene or polypropylene, and has a sheet shape as a whole. The air packing 4 has a sheet 41 and a plurality of bubble portions 42. The sheet 41 has a rectangular shape when viewed from the front, and its outer shape is larger than the bottom 21 of the main body of the container body 2B. The plurality of bubble portions 42 are formed at a distance from each other on one side of the sheet 41. Each bubble portion 42 contains air.

11 and 13, the container body 2B is provided with four body parts 211B. The main body portion 211B is integrally formed with the main body bottom portion 21 and protrudes downward from the main body bottom portion 21. Unlike the first embodiment, the body legs 211B are formed one by one in the vicinity of the four corners of the body bottom portion 21, not near the center portion of the body bottom portion 21.

The air packing 4 is disposed in the accommodation space 20 in a state where the surface on which the bubble portion 42 is formed faces the body bottom portion 21. As described above, the outer shape of the sheet 41 of the air packing 4 is larger than the main body bottom portion 21 of the container body 2B, but the air packing 4 is as shown in FIGS. 12 and 13. Similarly, it is arrange | positioned in the accommodation space 20 in the state which the edge part 411 was bent.

The lower surface of the air packing 4 is in contact with the bottom portion 21 of the main body, and the middle container 3 is placed on the upper surface of the air packing 4. The heavy container 3 is not restrained with respect to the container body 2B or the air packing 4, and is supported by contacting the upper surface of the air packing 4 only at the lower end 34b of the heavy container leg 34.

Moreover, the edge part 411 of the air packing 4 is arrange | positioned between the main body side wall part 22 of the container main body 2B and the middle container each part 34. As shown in FIG. 13, the height from the body bottom 21 to the top of the body side wall 22 is called H2, and the height from the body bottom 21 to the top of the edge 411 is called H4. In the lower surface, the height H4 is set to be 1/2 or less of the height H2. Specifically, when the height H2 from the body bottom portion 21 to the top of the body side wall portion 22 is about 37 mm, the height H4 from the body bottom portion 21 to the top of the edge portion 411 is It is set to about 15 mm. As shown in FIG. 12, in the corner part of the accommodation space 20, the curved edge part 411 is arrange | positioned so that it overlaps.

The air packing 4 arranged in this way mitigates the transmission of vibrations between the container body 2B and the heavy container 3 by deforming the bubble portion 42 containing air. That is, the air packing 4 functions as a cushioning material. The resonance frequency of the air packing 4 is set to be a value lower than the resonance frequency of the middle container 3.

Next, referring to Fig. 14, the operational effects of the transport container 1B will be described. 14 is an explanatory diagram for explaining a deformation of the transport container 1B. For ease of understanding, FIG. 14 shows only the XIII-XIII cross section of the transport container 1B.

As in the second embodiment, the top plate 31 of the heavy container 3 is deformed with the upper end 34a of the largely spaced middle container portion 34 as a point, so that its natural frequency is relatively low. As a result, even when vibration with a relatively high frequency is transmitted from the bottom portion 21 of the main body to the concave portion 32 of the fruit receiving portion 311 through the middle container portion 34, the resonance of the strawberry S and the resonance It becomes possible to suppress the accompanying epidermal damage.

In addition, in the transport container 1B, the container body 2B has four body parts 211B protruding downwardly formed on the body bottom part 21, and the body parts 211B are separated from each other.

According to this configuration, even when the bottom surface of the corrugated cardboard box or the like is distorted, as shown by broken lines 21 'and 211B', the body bottom portion 21 is easily deformed between the body portions 211B. You can follow the distortion. As a result, it is possible to stably contact the main body parts 211B with the bottom surface of the cardboard box or the like, thereby making it possible to make the contact range between the main body bottom part 21 and the bottom surface of the cardboard box constant.

The transport container 1B is provided with an air packing 4 which is a sheet-like cushioning material between the container body 2B and the middle container 3. Each of the heavy container parts 34 is supported by the main body bottom part 21 through the air packing 4.

According to this structure, it becomes possible to adjust the frequency of the vibration transmitted from the container body 2B to the heavy container 3 by the air packing 4. By setting the resonant frequency of the air packing 4 to be lower than the resonant frequency of the middle container 3, it becomes possible to suppress the resonance of the strawberry S due to the vibration and the damage to the epidermis accompanying it.

The edge portion 411 of the air packing 4 is bent, and the edge portion 411 is disposed between the main body side wall portion 22 and the middle container leg portion 34.

According to this configuration, even when the middle container 3 moves within the accommodation space 20 during transportation of the transport container 1B, the air packing 4 prevents the collision between the main body side wall part 22 and each of the heavy container parts 34. It can be relaxed by the edge portion 411 of the. As a result, it is possible to alleviate the impact on the strawberry S and suppress the damage to the epidermis of the strawberry S.

The height of the edge portion 411 of the air packing 4 is 1/2 or less of the side wall portion 22 of the main body.

According to this configuration, even if the edge portion 411 of the curved air packing 4 overlaps at the corner portion of the accommodation space 20, the middle container portion 34 of the heavy container 3 is air-packed 4 It can be easily prevented from being fixed to the side wall portion 22 of the body through the edge portion 411 of the.
