Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for maintaining the freshness of plants such as cut flowers when they are transported in a required bundle.
And a packaging material that retains the freshness of this plant.

[0002]

2. Description of the Related Art Conventionally, when cut flowers are collected and shipped by cut flower producers, the packaging method is to wrap the cut flowers at their roots, that is, cut edges, with paper containing water and pack them in a water-resistant cardboard box. Alternatively, a method is known in which the cut portion is wrapped with a water-containing paper and a plastic film and packed in a general cardboard box.

[0003] In a fresh flower retail store, when a cut flower or the like is conveyed, a bouquet in which various cut flowers having different stem thicknesses and branch branches are combined is conveyed without water supply, or the bouquet is A method is used in which the base is moistened with water-containing paper, wrapped with aluminum foil or a plastic film, and then packed in a cardboard box and transported.

[0004]

However, although cut flowers are packaged and then distributed through a distribution process, they are delivered to fresh flower retailers. The process, that is, the time for carrying is usually longer than one day and night, and in the former method, it is difficult to maintain the freshness of cut flowers because the amount of water supplied to the cut flowers is insufficient compared to the time consumed in this carrying. However, there is a problem that the cardboard box for packaging is severely damaged and the cut flowers are damaged. Further, in the latter method, since sufficient water retention is not ensured, there is a problem that when the bouquet is delivered from the retail store to the customer, the cut flowers lose their freshness and the commercial value thereof decreases significantly. ..

Under these circumstances, it has been desired to extend the freshness retention period of cut flowers, and various techniques have been devised for this. However, these technologies are not sure,
Both have drawbacks and problems.

For example, Japanese Utility Model Laid-Open No. 63-33757 discloses an example in which a polymer water-absorbing agent is put in a bag or tube and a cylinder formed of a waterproof material, and the water content of the polymer water-absorbing agent causes Although a method for holding the flower without holding it has been shown, this example has a drawback that it is difficult to insert and install the bouquet, and the workability of wearing the bouquet is poor and it is not practical. Further, Japanese Utility Model Laid-Open No. 63-82791 discloses a method of pouring water into a water reservoir of a flower support container and supplying the water to the flower by a capillary action of a sponge. There is an unavoidable drawback of water leakage due to falls. Further, in Japanese Utility Model Laid-Open No. 1-6851, a cut flower freshness holding container holding a water stopcock of a water-expandable material is shown at the upper end opening of a water holding container body, but the number of cut flowers held is only one. It is limited and cannot be applied to bouquets. Further, Japanese Patent Application Laid-Open No. 2-5812 discloses an example in which a water-resistant container and a water-immersive material are combined as a support storage container for cut flowers, but in this example, an opening is formed widely and a bouquet is formed. Since the opening cannot be closed after the insertion and mounting of the container, there is a drawback that transportation of the container and water leakage when the container falls are inevitable.

Therefore, in order to solve the above problems, the present invention does not easily leak water when a plant such as a cut flower is conveyed, and the packaging material for keeping the freshness of the plant does not leak, and even if it is used for a bouquet, it is attached. It is an object of the present invention to provide a plant freshness maintaining method and a plant freshness maintaining packaging material which can be easily carried out by the present invention.
