Abstract

PROBLEM TO BE SOLVED: To provide a fruit storage cushioning tool capable of reducing damage of a fruit without causing rubbing even if there is vibration in transport.SOLUTION: A fruit storage cushioning tool 1 is composed of a flexible sheet-like soft foamable synthetic resin sheet 2 having the length of 24 cm, a breadth of 16 cm and a thickness of 1 cm, and a plurality of through-holes 3 with a waterdrop shape are bored in the foamable synthetic resin sheet 2. In use, the fruit, for example, a strawberry S larger than the size of the through-holes 3 is placed on the through-holes 3. In the size of the through-holes 3, the size of about 50-80% of an external shape of the strawberry S to be placed is suitable. Thus, the strawberry S is softly held by line contact by an edge 3a of the through-holes 3 of the foamable synthetic resin sheet 2, and even when receiving vibration or the like generated in the transport, the vibration is absorbed by the foamable synthetic resin sheet 2, and motion of the strawberry S is reduced, and since the contact area with the foamable synthetic resin sheet 2 is also small, the occurrence of a flaw by the rubbing can be prevented.

Description

  The present invention relates to a fruit storage buffer for reducing the damage caused during transportation and distribution of fruit that is soft and fragile like strawberry, and a fruit storage method using the buffer.

  Normally, when shipping strawberries to the market, for example, a strawberry packed in several layers in a transparent synthetic resin container made of PET or the like is put in a cardboard box and transported. Yes.

  In addition, about 10-40 pieces of business-use strawberries or high-quality strawberries for gifts delivered to cake shops etc. are placed on a tray of foamed resin sheet made of polyethylene paper having a thickness of about 1-2 mm. A concave portion is formed, and one piece of strawberry stored in the concave portion is put in a cardboard box and shipped.

  Patent Document 1 discloses a fruit packaging container including a buffer container made of a flexible foamed synthetic resin sheet and a support container having shape retention.

JP 2010-64761 A

  However, if strawberries are stacked in a conventional container made of PET or the like, the strawberries come into contact with each other, which may damage the surface of the strawberries during transportation and distribution, thereby reducing the commercial value. Especially in the summer, the damage is likely to proceed from the surface damage, and the commercial value is greatly reduced.

  In addition, even when storing strawberries one by one in the recesses of the flexible foamed resin sheet tray, the strawberries move in the individual recesses of the tray during transportation and distribution, and the surface of the strawberries rubs against the recesses of the tray. Therefore, it is inevitable that the surface of the strawberry is damaged.

  Moreover, even if it uses the container for fruit packaging of patent document 1, compared with the conventional packaging container, although there is an effect which reduces the damage given to a fruit, since the fruit is mounted in the recessed part of a foamed resin tray, It is impossible to prevent the fruit from rubbing in the concave portion of the tray due to vibration during transportation, distribution, etc., which is not a fundamental solution.

  The object of the present invention is to eliminate the above-mentioned problems, and even when there is vibration during transportation and distribution, the fruit does not rub against the container and can greatly reduce damage to the fruit. It is in providing the storage method of the fruit which used the tool and this buffer.

  In order to achieve the above object, a fruit storage buffer according to the present invention has a sheet-like soft foamable synthetic resin material having a plurality of through-holes formed by curves for holding a fruit at its edge. It is characterized by that.

  Further, the storage method using the fruit storage buffer according to the present invention is a fruit storage buffer comprising a plurality of sheet-like soft foamable synthetic resin materials having a plurality of through holes formed in a curve. Thus, a plurality of fruits are sandwiched from below and above, and the fruits are respectively held by the edges of the through holes.

  According to the fruit storage buffer and the fruit storage method using the buffer according to the present invention, the soft foamable synthetic resin material does not scratch the fruit even when vibration is applied during transportation. Compared with the case of using fruit packs and trays, fruit damage during transportation can be greatly reduced.

It is a perspective view of the buffer for fruit storage of Example 1. FIG. It is a top view. It is sectional drawing along the AA line of FIG. It is an expanded sectional view of the state which mounted the strawberry on the buffer for fruit storage. It is a perspective view of the state which mounted the strawberry on the buffer for fruit storage. It is a top view of the buffer for fruit storage of Example 2. It is a perspective view of the state which hold | maintained the strawberry with the upper and lower two fruit storage buffer of Example 3. FIG.

  The present invention will be described in detail based on the embodiments shown in the drawings.

  1 is a perspective view of a fruit storage buffer 1 for example for a strawberry in the embodiment, FIG. 2 is a plan view, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. The fruit storage buffer 1 is composed of a foamable synthetic resin sheet 2 made of, for example, a flexible polyurethane foam (PUF) having a flexibility of 24 cm in length, 16 cm in width, and 1 cm in thickness, for example. The sheet 2 is provided with a plurality of water-drop shaped through holes 3 that approximate the outer shape of a strawberry.

  Soft polyurethane foam has open cells, is very flexible to compression, and has good resilience.

  In this embodiment, a soft polyurethane foam material is used for the foamable synthetic resin sheet 2, but various flexible and elastic foamable synthetic resin materials such as polyethylene foam are used in addition to the soft polyurethane foam material. You can also.

  As shown in FIG. 1, the number of through-holes 3 is typically 24 in total in 4 rows and 6 rows, but a total of 20 in 4 rows and 5 rows, 5 in rows and 6 in rows. A total of 30 rows may be used, and the size of the through holes 3 may be changed as appropriate according to the size of the strawberry.

  The foamable synthetic resin sheet 2 can be used repeatedly after transportation and distribution, and the color of the foamable synthetic resin sheet 2 is preferably black or dark gray. By using black or dark gray during repeated use, discoloration due to deterioration such as ultraviolet rays becomes inconspicuous, and when combined with a red strawberry, there is also an effect that the color of the strawberry is reflected.

  Moreover, as shown in FIG. 2, the symmetrical center line C of the shape of the water-drop-shaped through-hole 3 is directed in an oblique direction with respect to the side portion of the rectangular foamable synthetic resin sheet 2. By placing the strawberry so that the pointed tip 3b of the water-drop shaped through hole 3 becomes the tip of the strawberry, the strawberry can be efficiently arranged on the foamable synthetic resin sheet 2 having a predetermined area.

  The shape of the through hole 3 may be a water drop shape or a substantially circular shape including an ellipse, and the edge 3a on the through hole 3 is formed from a smooth curve that matches the shape of the through hole. When storing loquats other than strawberries, the shape of the through hole 3 is preferably an egg shape, and is preferably matched to the type and shape of the fruit.

  In use, a strawberry S larger than the size of the through hole 3 is placed on the edge 3a on the through hole 3 as shown in FIGS. The size of the through hole 3 is preferably about 50 to 80% of the outer shape of the strawberry S to be placed. Even if there is some variation in the size of the strawberries S, the strawberries S are held by the through holes 3 without contacting each other. The strawberry S is softly held by the line contact by the edge 3a of the through hole 3, and even when subjected to vibrations or the like generated during transportation, the vibrations are absorbed by the foamable synthetic resin sheet 2 and the vibration applied to the strawberry S is small. Moreover, since the contact area of the strawberry S with the foamable synthetic resin sheet 2 is small, it is possible to prevent scratches due to rubbing.

FIG. 6 is a plan view of the fruit storage buffer 1 ′ according to the second embodiment, which is similar to the first embodiment in that a plurality of waterdrop-shaped through holes 3 ′ are formed. Side portions around the through-hole 3 ′ are formed in a jagged shape in a small wave shape when viewed from above. This shape increases the frictional force on the strawberry S and increases the holding force.
Moreover, in the buffer 1 for fruit storage of Example 1, when the damage | wound occurs in the edge 3a repeatedly during use, it must stand out and must be discarded, but in Example 2, the damage generated in the edge 3a There is also an advantage that it becomes difficult to distinguish.

  As described in Examples 1 and 2, it can be shipped by placing the strawberry S on the foamable synthetic resin sheet 2 which is the buffer 1 for storing fruit, but more reliably occurs in the strawberry S. In order to prevent the damage | wound which carries out, it is preferable to use the buffer 1 for fruit storage which consists of two foamable synthetic resin sheets 2 of an upper stage and a lower stage.

  That is, as shown in FIG. 7, the foamable synthetic resin sheet 2 having the same shape is further deposited on the strawberry S placed on the foamable synthetic resin sheet 2.

  The strawberry S is held by the lower edge 3a of the through-hole 3 of the upper foamable synthetic resin sheet 2 and the upper edge 3a of the lower foamable synthetic resin sheet 2, so that the first foamable synthetic resin Rather than holding only the resin sheet 2, the strawberry S can be prevented from being damaged and transported stably.

  Further, the thickness of the upper foamable synthetic resin sheet 2 is adjusted, and the strawberry S is further placed on the upper edge 3a of the upper foamable synthetic resin sheet 2, and the foamable synthetic resin sheet 2 is further placed thereon. May be applied. In this case, the strawberries S for two stages are held using the foamable synthetic resin sheets 2 on the upper, middle and lower stages.

  At the time of shipment, the strawberry S sandwiched from above and below by a plurality of foamable synthetic resin sheets 2 as described above can be shipped in a cardboard box, a decorative box, a wooden box or the like. As a result, even if vibration is applied during transportation, the vibration is absorbed by the plurality of foamable synthetic resin sheets 2 and vibration is hardly transmitted directly to the strawberry S.

  In addition to strawberries, the present invention can also be applied to storage of fruits such as loquat, figs, peaches, cherries, mangoes, and tomatoes that are soft and easily damaged. In this case, the shape of the through-hole 3a may be matched to the shape and size suitable for the type of fruit to be applied.
