Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cushioning material used for packing strawberries and a strawberry package using the cushioning material.
[0002]
[Prior art]
The fruits and vegetables are boxed through a cushioning material so that they are not damaged before being transported from the producer to the consumer. In particular, fruits and vegetables that are extremely susceptible to damage, such as strawberries, are important to be boxed with a flexible cushioning material so that local forces do not act on the surface of the fruits and vegetables. As a cushioning material for fruits and vegetables that are easily damaged, such as strawberries, soft plastic foamed into a sheet shape and further molded into a shape with a recess for containing the fruits and vegetables is used. This cushioning material is used for packaging fruits and vegetables that are easily damaged, such as strawberries and peaches.
[0003]
[Problems to be solved by the invention]
However, it is necessary to prepare a cushioning material having the above-described structure according to the size and shape of the strawberry to be boxed. This is because the size and shape of the fruits and vegetables put into the recesses are specified so as not to be damaged. For example, when large fruits and vegetables are put into small recesses, the periphery of the recesses locally contacts the fruits and vegetables and damages the fruits and vegetables. On the other hand, if small fruits and vegetables are put in the large recesses, the fruits and vegetables cannot be held so as not to move, and the fruits and vegetables move and collide during transportation, resulting in damage to the collision portion. For this reason, the actual situation is that a large number of cushioning materials produced exclusively for strawberry boxing are used. The cushioning material, which is restricted by the size and shape of the fruits and vegetables that can be stored, not only takes time and effort to manufacture, but also increases the manufacturing cost. Since a large number of cushioning materials are stocked, there is a drawback that it takes time to manage the stock.
[0004]
In addition, fruits and vegetables can be stored in high-value products by changing the storage posture. For example, strawberries are generally packed in a posture with the leaf portion facing downward from the side, but can be packed in a fresh image with green leaves and stems by packing the leaf portion upward. However, strawberry has a relatively similar shape in the upper part with leaves, but the shape of the lower part on the opposite side of the leaves differs significantly depending on the fruit. For this reason, even if it is a strawberry of the same magnitude | size, it cannot put in the recessed part shape | molded in the specific shape, and cannot hold | maintain in an ideal state. This is because the shape of the strawberry and the shape of the recess are significantly different, and the cushioning material locally contacts the strawberry and damages the contact portion. For this reason, even if it selects and uses the buffer material which shape | molded the recessed part according to the magnitude | size of fruit and vegetables, there exists a fault which cannot be boxed so that it may not be damaged depending on the attitude | position which packs fruit and vegetables.
[0005]
The present invention has been developed for the purpose of solving such drawbacks. An important object of the present invention, a strawberry size and shape are different, while boxed in various postures, to provide a cushioning material for strawberries can be reduced damage, strawberries of packages using this cushioning material It is in.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment described below exemplifies a cushioning material and a package for embodying the technical idea of the present invention, and the present invention does not specify the cushioning material and the package as follows.
[0011]
Further, in this specification, in order to facilitate understanding of the scope of claims, the numbers corresponding to the members shown in the embodiments are referred to as “claims” and “means for solving the problems”. It is added to the member shown by. However, the members shown in the claims are not limited to the members in the embodiments.
[0012]
The cushioning material 1 shown in FIG. 1 is disposed between and below the fruits and vegetables S that are strawberries, and is packed so as not to damage the strawberries S that are fruits and vegetables. The cushioning material 1 is manufactured by molding a soft plastic into a sheet having a predetermined thickness. The cushioning material 1 is most preferably a soft urethane foam. However, a soft plastic foam other than soft urethane and having a cushioning property, for example, a soft vinyl chloride foam or EVA foam can be used. As the soft plastic, a closed-cell foam or an open-cell foam can be used. Since the closed cell plastic foam can provide cushioning properties with closed cells, the expansion ratio can be increased to hold the fruits and vegetables firmly. In addition, since the open-cell foam can be made extremely flexible, it is possible to reduce damage by making soft contact with particularly fragile fruits and vegetables.
[0013]
[0014]
The cushioning material 1 is provided with laying line portions 2 laid under the fruits and vegetables S and bent line portions 3 provided between the laying line portions 2 alternately in parallel. The bent line part 3 has flexibility that is easier to bend than the laying line part 2. As shown in the cross-sectional view of FIG. 1, the cushioning material 1 has the laying line portion 2 disposed under the fruits and vegetables S and the bent line portions 3 disposed at the boundaries of the fruits and vegetables S. The folding line part 3 is bent in the rising direction with respect to the laying line part 2, and is further bent so that the middle is folded, and a buffer wall 4 is provided between the fruits and vegetables S arranged adjacent to each other.
[0015]
The width of the laying line part 2 and the bent line part 3 is specified by the size of the fruits and vegetables S to be stored. As shown in FIG. 1, the buffer wall 4 has the laying line portion 2 laid under the fruits and vegetables S, the bent line portion 3 is U-curved to form the buffer walls 4, and the buffer walls 4 are arranged on the boundaries of the fruits and vegetables S. Set up. The buffer material 1 adjusts the height of the buffer wall 4 comprised by the bending line part 3 so that the fruit and vegetables S of various sizes can be accommodated, and changes the space | interval of the adjacent buffer wall 4. FIG. When storing small fruits and vegetables S, as shown in FIG. 2 , the buffer material 1 is made high and the space | interval of the adjacent buffer material 1 is narrowed. When storing large fruits and vegetables S, as shown in FIG. 3 , the buffer wall 4 is lowered and the interval between the adjacent buffer materials 1 is increased. The reason why the buffer wall 4 can be lowered to widen the interval between the buffer walls 4 is that a part of the bent line portion 3 can be laid under the fruits and vegetables S in the same manner as the laying line portion 2.
[0016]
Buffer material 1, since the housing of fruits or vegetables S as described above, the width of the laying line portion 2, substantially equal to the outer diameter of the smallest fruit or vegetable S. Cushioning material 1 for packing a Strawberry as about 3cm width of laying line section 2, it can be used in packing the most strawberries. However, the buffer material for strawberry can also make the width | variety of a laying line part into 2-4 cm. Furthermore, the buffer material for strawberries sets the width | variety of the bending line part to about 5 cm in the state extended | stretched planarly. The width of the bent line portion can also be set to 3 to 7 cm in the buffer material for strawberries.
[0017]
The bent line part 3 is U-shaped to constitute the buffer wall 4. Therefore, the height of the buffer wall 4 is ½ or less of the width of the bent line portion 3. Therefore, the width of the bent line part 3 is, for example, 1.2 to 2.5 times, preferably 1.3 to 2 times the width of the laying line part.
[0018]
The bent line portion 3 of the cushioning material 1 has flexibility that is easier to bend than the laying line portion 2. In other words, the laying line part 2 is harder to deform than the bent line part 3, and absorbs the impact in the vertical direction of the fruit and vegetables S without being completely crushed by placing the fruit and vegetables S. The buffer material 1 of FIG. 1 makes the laying line part 2 thicker than the bending line part 3, and makes the bending line part 3 easier to bend than the laying line part 2. The cushioning material 1 is made of a soft plastic foam such as soft urethane, and the laying line portion 2 is formed thicker than the bent line portion 3.
[0019]
In the strawberry cushioning material 1 which is a soft plastic foam, the laying line portion 2 has a thickness of about 2 mm. However, it is necessary to change the thickness of the laying line portion in consideration of the weight of the fruits and vegetables stored and the ease of damage. The cushioning material used for heavy fruits and vegetables increases the cushioning action by thickening the laying line part. Light fruit and vegetables cushion the laying line. Therefore, although the thickness of the laying line part which is a soft plastic foam changes with fruits and vegetables, it can be 1-5 mm, for example. If the laying line portion is thickened, the fruits and vegetables can be stored so as not to be damaged, but the manufacturing cost becomes high. Therefore, the thickness of the laying line portion is set to an optimum thickness in consideration of the degree of easy damage to fruits and vegetables and the manufacturing cost.
[0020]
[0021]
In the strawberry cushioning material 1 which is a soft plastic foam, the thickness of the bent line portion 3 is about 1 mm. As with the laying line portion 2, the thickness of the bent line portion 3 is also changed in consideration of the weight of the stored fruits and vegetables S and the ease of damage. The buffer material used for heavy fruits and vegetables has a thick bent line portion, and the buffer material for light fruits and vegetables has a thin bent line portion. Therefore, the thickness of the fold line portion is a soft plastic foam, it can be 0.5~3mm For example other. If the bent line portion is made thicker, the fruits and vegetables can be stored so as not to be damaged, but the manufacturing cost increases. Therefore, the thickness is set to an optimum thickness considering the degree of easy damage to the fruits and vegetables and the manufacturing cost.
[0022]
The bent line portion 3 is preferably made of a material having an elastic restoring force. Soft plastic foam has elastic restoring force. In particular, a foam formed by closed cell molding of soft urethane has an excellent elastic restoring force. Therefore, if this laying line part 2 is U-curved and becomes the buffer wall 4, it will contact the fruit and vegetables S in the state with the cushion excellent in the elastic restoring force of itself. Therefore, the impact is absorbed by the elastic restoring force, and the fruits and vegetables S are stored so as not to be damaged. The cushioning material 1 shown in the perspective view of FIG. 4 has a shape in which the bent line portion 3 is bent in the rising direction with respect to the laying line portion 2 and is bent without forcibly bending the bent line portion 3. It is molded into. Since this cushioning material 1 can bend the folding line portion 3 easily, the fruits and vegetables S can be boxed efficiently.
[0023]
[0024]
The buffer material 1 is used as shown in the sectional view of FIG. That is, the package of fruits and vegetables S shown in FIG. 1 protects the fruits and vegetables S by placing the cushioning material 1 on the box 5 that stores the fruits and vegetables S and arranging the cushioning material 1 between the fruits and vegetables S. Store. Between the fruits and vegetables S, a U-curved buffer wall 4 is disposed to prevent the fruits and vegetables S from colliding with each other.
[0025]
【The invention's effect】
The buffer material and package for strawberries which are fruits and vegetables of the present invention have the feature that damage can be reduced while packaging fruits and vegetables strawberries of different sizes and shapes in various postures. That is, the cushioning material of the present invention is provided with laying line portions laid under the strawberry of fruits and vegetables and bent line portions provided between the laying line portions alternately and in parallel. Is placed under the strawberry of the fruit and vegetables , and the folding line part is folded in the rising direction with respect to the laying line part, and is folded so that the middle of the folding line part is folded and arranged adjacent to each other. This is because a buffer wall is arranged between the strawberries of the fruits and vegetables. This buffer material can accommodate fruit and fruit strawberries between the buffer walls while adjusting the height of the buffer walls formed by the bent line portions and changing the interval between the adjacent buffer walls. Therefore, it is possible to reduce the damage while boxing fruit and fruit strawberries of different sizes and shapes in an ideal state in various postures.
