In the container having the conventional shock absorption as described above, perishable fruits and vegetables are accommodated and held in a soft member such as a foam material, and a hard member such as plastic is provided on the outside thereof, so that the fruit vegetables during transportation are provided. It is configured to reduce the kind of damage.
Such a container configuration has a problem that the manufacturing cost increases because of the dual structure of the soft member and the hard member having a three-dimensional shape.
In addition, since the container has a three-dimensional shape and a large height, there is a problem in that the container is bulky and space is increased when the container is stored, transported and transported without containing the fruits and vegetables.

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that the manufacturing cost can be reduced while the impact vegetables that protect perishable vegetables and can reduce the damage during transportation can be reduced. It is in the point which provides the buffer material for fruit vegetables which is not bulky at the time of storage, conveyance, and transport in the state which does not contain the fruit.

In order to solve the above problems, the buffer material for fruit vegetables according to the present invention overlaps two airtight sheet-like materials having flexibility and penetrates in the thickness direction of the sheet-like material. It consists of a polymer sheet in the form of having through-holes,
While providing an adhesive portion on the outer periphery of the polymer sheet and the periphery of the through hole, and by providing a gas filling port with a check valve, the polymer sheet can be filled with gas,
The portion around the through-hole of the polymer sheet is a gas buffer that swells three-dimensionally when gas is filled into the polymer sheet from the gas filling port,
The concave portion formed in the through-hole and the periphery thereof by the gas buffering portion is used as a storage unit for fruit and vegetables (Claim 1).

According to such a configuration, two sheets of flexible and airtight sheet-like material are overlapped, and the required portions of the polymer sheet-like material having a through-hole penetrating in the thickness direction are bonded by heat welding or the like. The gas can be filled. Then, by filling the polymerization sheet-like material with a gas, a three-dimensionally bulging gas buffer portion is formed, and the through hole and the recessed portion formed in the periphery of the gas buffer portion are used as a fruit vegetable storage portion. For this reason, perishable fruits and vegetables are stably held in the recessed portion and are shock-absorbed by the gas buffer portion. Therefore, it can be stored, transported or transported while appropriately protecting perishable fruits and vegetables with the cushioning material for fruits and vegetables.
In addition, the thickness and rigidity of the gas buffer portion can be changed by changing the amount of gas to be filled. Therefore, the thickness and rigidity of the gas buffer portion can be finely set so as to be suitable for protecting perishable fruits and vegetables housed in the recessed portion formed by the gas buffer portion.
In addition, two sheets of flexible airtight sheet-like material are overlapped, and necessary portions of the polymer sheet-like material in the form having a through-hole penetrating in the thickness direction are adhered by heat welding or the like, A fruit and vegetable cushioning material can be constructed simply by causing the portion to swell in a three-dimensional shape when filled with gas. Therefore, since the structure of the buffer material for fruit vegetables is simple, manufacturing cost can be reduced.
Furthermore, in the state which has not filled the fruit buffer material with the gas, it has a flat form and has flexibility. Therefore, when storing, transporting and transporting only the fruit and vegetable buffer material without containing the fruit and vegetables, it is not bulky and can be folded freely so that it is compact.

Here, a connecting means for connecting the two sheets of the polymer sheet-like material in a state where they are overlapped in the vertical direction, or a portion where one piece of the polymer sheet-like material is folded at the center and overlapped with each other. It is preferable that a connecting means for connecting is provided (claim 2).
According to such a configuration, the upper and lower polymer sheet-like materials (upper and lower two polymer sheet-like materials and one polymer sheet-like material are folded by connecting means such as a snap button and a hook-and-loop fastener that can be connected with one touch. Can be easily connected. By storing perishable fruits and vegetables in the concave part of the polymer sheet and connecting the upper and lower polymer sheets, the fruits and vegetables can be stably held in a state where the fruits and vegetables are sandwiched between the upper and lower polymer sheets. The shock absorber is absorbed by the front and rear, the left and right, and the upper and lower gas buffer portions surrounding the fruit vegetables. Therefore, there is no need to provide a cushioning material separately, and it is not necessary to cover the whole with the covering film, so the cushioning material and the covering film are not wasted, and the work of arranging the cushioning material or covering the whole with the covering film is not necessary. It becomes unnecessary.
In addition, since it is easy to release the connection between the upper and lower polymer sheets, it is easy to take out the fruits and vegetables from the fruit and vegetable buffer material.

The polymer sheet is more preferably rectangular in plan view (Claim 3).
According to such a structure, the space efficiency at the time of storing, transporting, or transporting the fruit and vegetable buffer material containing perishable fruit and vegetables in a box or a bag is increased.

Furthermore, it is more preferable that the through hole has a polygonal shape, a circular shape, or an elliptical shape in plan view.
According to such a structure, the shape of the recessed part which accommodates perishable fruits and vegetables changes by selecting the shape of a through-hole from polygonal shape, circular shape, or elliptical shape. Therefore, by selecting the shape of the through hole from the shape so that the shape of the recessed portion matches the shape of the fruit and vegetables to be accommodated, the state where the fruit and vegetable are held in the recessed portion is more stable.
In addition, since the polygonal shape, the circular shape, or the elliptical shape is a simple shape, the processing cost for forming the through hole does not increase.

In order to solve the above problems, the method for storing and transporting fruit vegetables according to the present invention stores or transports fruit vegetables using the buffer material for fruit vegetables (Claim 5).
According to such a method for storing and transporting fruit vegetables, since the fruit vegetables are stored or transported using the buffer material for fruit vegetables, the same effects as the buffer material for fruit vegetables are exhibited.

Here, it is preferable to store or transport the fruits and vegetables by storing the fruits and vegetables container containing the fruits and vegetables in the recessed part of the cushioning material for fruits and vegetables in a foamed synthetic resin container. 6).
According to such a method for storing and transporting fruit vegetables, a foamed synthetic resin container is obtained by storing the fruit vegetable container containing the fruit vegetables in the recessed portion of the buffer for fruit vegetables in the foamed synthetic resin container. Since it has elasticity and excellent shock absorption, the effect of protecting perishable fruits and vegetables and reducing damage during storage and transportation is further increased.
In addition, since the foamed synthetic resin container is excellent in heat insulation, the quality deterioration of fruits and vegetables can be suppressed by storing the cold insulating material in the container.

In addition, the temperature of the gas filled from the gas filling port is higher than the temperature at which freezing or low temperature damage occurs in the fruits and vegetables housed in the recess, and is 10 ° C. or less, more preferably 5 ° C. or less. Further preferred (claim 7).
According to such a method for storing and transporting fruits and vegetables, the temperature of the gas filled from the gas filling port is higher than the temperature at which the fruits and vegetables are frozen or cold damage occurs. No low temperature damage occurs in fruits and vegetables.
In addition, since the temperature of the gas filled from the gas filling port is a relatively low temperature of 10 ° C. or less, more preferably 5 ° C. or less, the fruits and vegetables can be cooled, so that the quality deterioration of the fruits and vegetables can be suppressed.

As described above, according to the buffer for fruit vegetables and the method for storing and transporting fruit vegetables according to the present invention, the following effects are mainly obtained.
(1) Perishable fruits and vegetables are stably held in the recesses of the buffer for fruit vegetables and absorbed by the gas buffer of the buffer for fruits and vegetables, greatly reducing damage during storage and transportation it can.
