  The fruit storage container 1 according to the present invention is characterized by comprising a side wall 3 that expands upward from an opening 2 at the lower end and an opening 4 at the upper end of the side wall 3.

  As shown in FIG. 1, the fruit storage container 1 according to the present invention is a portion that includes a lower end opening 2, a side wall 3, and an upper end opening 4 of the side wall 3, and stores a fruit F therein. As shown in FIG. 2, the fruit storage container 1 of the present invention can form a bottom 2 a in the opening at the lower end. By providing the bottom part 2a, it is possible to prevent deformation or scratches due to foreign matters mixed in from below. The number of the fruit storage container 1 of the present invention may be one, or two or more as shown in FIG.

Hereinafter, the fruit storage container in which the bottom 2a is formed in the opening 2 at the lower end will be mainly described as an example.
In the present invention, the size and shape of the bottom 2a are not particularly limited, and may be appropriately designed according to the fruit to be stored. As shown in FIG. 4, if the bottom 2a is provided with wave-shaped irregularities as shown in FIG. 4, it becomes a cushion even when the fruit hits the bottom 2a, and the fruit is hardly damaged. The direction and shape of the unevenness are not particularly limited, and may be a shape (corrugated plate) in which straight concave portions and convex portions are continuously provided, or a shape in which concentric concave portions and convex portions are continuous.

In this invention, the side wall part 3 is made into the shape expanded diameter upwards from the bottom part 2a. For example, when the bottom surface is circular, the side wall portion 3 has a cylindrical shape whose diameter is increased upward. When the fruit F is stored in the fruit storage container 1 of the present invention, since the side wall 3 is reduced in diameter downward, even if the fruit has a different size, the large fruit F has a side wall. The small fruit F is supported in contact with the side wall 3 relatively below the side wall 3 and supported in contact with the side wall 3 relatively above the part 3, and the fruit F is not in contact with the bottom 2a. It is stored with.
Therefore, the inclination of the shape that expands upward, that is, the shape that contracts downward, is supported in contact with the side wall portion 3 from the largest to the smallest in consideration of the size of the fruit F to be stored. It is designed so that the fruit is stored without contacting the bottom 2a. By designing in this way, if one kind of fruit storage container is prepared, it can be applied to fruits having different sizes, so that it is efficient and economical.
When the fruit comes into contact with the bottom of the container as in a conventional storage container, the total gravity of the fruit is applied to the lower part in contact with the bottom of the fruit container, so that this part is easily deformed or damaged. On the other hand, in the storage container of the present invention, since the fruit does not contact the bottom of the container, such a problem does not occur. Further, in the case of a storage container having no bottom, since the fruit does not contact the bottom surface of the cardboard box or the like, deformation and scratches on the lower part of the fruit are prevented.

About the side wall part 3, by providing a wavy unevenness in at least a part of the side wall part 3, preferably the entire part in contact with the fruit F, the unevenness becomes a cushion, and the fruit F is hardly damaged. Moreover, since the fruit F is firmly hold | maintained by an unevenness | corrugation, it becomes difficult to slide down. For this reason, since the fruit F to be held is less likely to be crushed or damaged, the commercial value is maintained.
The shape of the unevenness is not particularly limited, but as shown in FIGS. 5 to 7, a shape (corrugated plate shape) in which linear concave portions and convex portions are continuous is preferable. The direction of the unevenness is not particularly limited, but examples include a horizontal direction (see FIG. 5), a vertical direction (see FIG. 6), and an oblique direction (see FIG. 7). In particular, when the direction of the unevenness is an up-down direction or an oblique direction, the convex portion protruding outward as viewed from the inside serves as a ventilation path and maintains good freshness, It is preferable because water vapor is allowed to escape upward to easily prevent condensation and generation of mold due to condensation.

  The above-mentioned fruit storage container can be used with a simple lid with paper, film, foamed resin sheet or the like in the upper container of the fruit F after storing the fruit F, or on the upper part of the container. As shown in FIG. 8, it is also possible to attach the lid 5 to the opening 4 at the upper end. It is preferable that the lid 5 is attached to the opening 4 so that it can be opened with a relatively weak force (easy opening) because the fruit F in the contents can be easily taken out. Examples of the easy-opening means include a zipper (perforation) and a notch (notch), and easy-peelable (easy peelable) adhesion by heat sealing. When adhering by heat sealing, corona discharge treatment, flame treatment, anchor coating treatment, etc. can be performed as necessary.

  When attaching the lid 5 to the opening 4, it is preferable to provide a knob 5 a as illustrated in FIG. 9. In FIG. 9, an overhang having a shape that can be easily pinched with a finger is provided on at least a part of the lid 5 to form a knob 5 a. If it does in this way, when removing lid 5, it can be removed by pulling up with this knob part 5a. Moreover, it is good also as a knob part by projecting on the outer periphery of the opening part 4 on a concentric circle. In addition, in FIG. 8, the cover body 5 has shown the state opened partially.

  The fruit storage container 1 of the present invention is preferably provided with a vent 6 for discharging gas or water vapor emanating from the fruit F to the outside of the container. The position where the vent hole 6 is provided is not particularly limited, and is provided in at least one of the bottom 2a, the side wall 3 and the lid 5.

  In the case where the bottom portion 2a is provided with irregularities, as shown in FIG. 10, the vent hole 6 may be provided in the convex portion 2b protruding outward as viewed from the inside, or the side wall portion 3 is provided with irregularities. As shown in FIG. 11, the vent hole 6 may be provided in the convex portion 3 a that protrudes outward as viewed from the inside of the side wall portion 3. By providing the vent hole 6 in this manner, a gap corresponding to the convex portion 2b or 3a protruding outward is formed between the fruit F and the bottom 2a or the side wall portion 3, and this gap is formed between the gas or water vapor passage. This is preferable.

The fruit storage container 1 of the present invention is not limited to the case where the diameter is increased linearly upward from the opening 2 or the bottom 2a at the lower end, and as shown in FIGS. May be different. The fruit storage container 1 shown in FIG. 12 includes a side wall portion 3 that is gradually enlarged from the opening 2 at the lower end to the middle and then gradually increased in diameter. In the fruit storage container 1 of FIG. 13, a bottom 2a is provided at an opening at the lower end of the fruit storage container 1 shown in FIG. 12, and a lid 5 is formed at the opening 4 at the upper end.
Although the example which has the side wall part 3 bent in one place was shown in the fruit storage container 1 shown in FIG. 12, FIG. 13, it is good also as the side wall part 3 bent in multiple places as needed.
Since the fruit stored in the fruit storage container 1 having such a bent side wall is supported by the side wall at two places, the upper part and the lower part of the bent part, the force applied to the fruit is dispersed and damage is prevented. At the same time, the gap between the fruit formed in the bent portion and the inside of the side wall portion becomes a vent hole to maintain the freshness of the fruit.

  In the fruit storage container 1 of the present invention, the fruits F are individually stored one by one. It is preferable that the fruit F is supported by the side wall part 3 and stored so that the fruit F does not contact the bottom part 2a. In the case of a storage container that does not have the bottom 2a, the storage container is stored so as not to contact the bottom surface of a cardboard box or the like. The fruit F to be stored is not particularly limited, and in particular, figs and loquats that are soft and easily damaged by transportation and handling are preferable. Figs and loquats are stored with the fruit axis (the part of the stem supporting the fruit) facing the bottom 2a.

The fruit storage container of the present invention can also be used with a support frame to form a fruit storage system.
In the example shown in FIG. 14, the support frame 7 includes a support portion 7 a and a leg portion 7 d that supports the support portion 7 a, and the support hole 7 b into which the fruit storage container 1 can be inserted. The support hole 7b is formed larger than the bottom of the fruit container 1 and smaller than the upper end of the side wall 3.

  In the present invention, the shape of the support portion 7a is not particularly limited, but considering the ease of storage, display, or transportation, it is preferable that the shape of the support portion 7a be a plate having a rectangular outer shape as shown in FIG.

The support portion 7a is formed with a support hole 7b, and the fruit storage container 1 is inserted into the support hole 7b.
Since the support hole 7b is larger than the bottom part 2a (or the opening part 2 at the lower end) of the fruit storage container 1 and smaller than the upper end part of the side wall part 3, when the fruit storage container 1 is inserted into the support hole 7b, The fruit storage container 1 is engaged with the support hole 7b in the middle, and the fruit storage container 1 is suspended from the support hole 7b as shown in FIG. As described above, since the fruit storage container 1 is suspended from the support hole 7b, for example, when vibration is applied during transportation, the shock due to vibration is absorbed by the storage container 1 moving up and down in the support hole 7b. As a result, the impact that is directly transmitted to the fruit in the storage container 1 is mitigated. In FIG. 15, the flange portion to which the lid of the storage container 1 is attached is not in contact with the upper surface of the support portion 7a, but may be suspended so as to contact.

  If the fruit storage container 1 is simply suspended from the support hole 7b, the fruit storage container 1 may swing from side to side during transportation, which may be unstable. Therefore, in order to stably support the fruit storage container 1 even during transportation, a skirt portion 7c for supporting the fruit storage container 1 can be suspended from the edge of the support hole 7b. Specifically, for example, as shown in FIG. 16, the skirt portion 7 c may be shaped along the peripheral surface of the side wall portion 3 of the fruit storage container 1.

  The support frame body 7 of the present invention is provided with a leg portion 7d for supporting the support portion 7a. The shape of the leg portion is not particularly limited, but in the example shown in FIGS. 14 to 16, the leg portion is provided on two opposing sides of the rectangular support portion 7 a. If necessary, it may be provided on three or four sides of the support portion 7a, and four rod-like members suspended from the four corners of the support portion 7a may be used as the leg portions.

The material of the fruit storage container of the present invention is not particularly limited, and synthetic resin, paper, a laminate of paper and synthetic resin, a nonwoven fabric, and the like can be used. Further, the container body and the lid may be manufactured from the same material, or may be manufactured from different materials.
The synthetic resin is not particularly limited, and examples thereof include polyolefin resins such as polyethylene and polypropylene, polystyrene resins, vinylidene chloride resins, polyamide (nylon) resins, polyester resins, and the like. In particular, polystyrene resins and polyester resins have high transparency. Molding from a film or sheet into a container is convenient because the contents can be confirmed, and the rigidity is high and the deep drawability is excellent. Biodegradable plastics such as polylactic acid resin, polybutylene succinate, polyamide 11, polyhydroxybutyric acid, biomass plastics, and the like can also be used.
Although it does not specifically limit as paper, Kraft paper, quality paper, parchment paper, glassine paper, etc. are mentioned. These materials can be employed in consideration of oxygen permeability, carbon dioxide permeability, gas barrier properties, moisture barrier properties, and the like.

  In the fruit storage container 1 of the present invention, it is preferable that a film or a sheet is formed by deep drawing, and in particular, a plurality of fruit storage containers are formed by deep drawing. It is preferable to use a foamed sheet such as polystyrene foam as the sheet because the fruit is protected by the cushioning property of the material itself. In the case of laminating paper and resin, either the paper side or the resin side may be the inside (or outside) of the fruit storage container 1.

  In the fruit storage container 1 of the present invention, if at least one of the bottom part 2a, the side wall part 3, and the lid 5 is made of a transparent resin, the type and state of the fruit F in the fruit storage container 1 can be easily visually confirmed. is there.
