2. Description of the Related Art Conventionally, fresh foods such as vegetables and fruits are stored in a corrugated box made of ordinary paper pulp fiber and transported to the market for sale in a market including a grocery store. Were stored in a cool box or refrigerated case, and were displayed and preserved. In order to transport fresh flowers such as orchids from the production area, special chemicals were applied to the roots to maintain their freshness.

[0003]

However, the above-mentioned transportation method and storage method have the following problems. Many fresh foods such as vegetables and fruits can only be stored for 4 to 5 days after they are shipped to the market.
Expensive equipment such as a refrigerator and a refrigerating case was required for storage. In addition, when even one defective product whose freshness is deteriorated during storage occurs, a bad odor is generated, and the bad odor affects other non-defective products, resulting in a decrease in commercial value. Furthermore, even if fresh flowers such as orchids are transported by aircraft and treated with the chemicals as described above, there is a limit that the preservation days are several days. Therefore, as for the shipping side of fresh foods and fresh flowers, if there is a large amount of products that can be provided to the market, even if you want to sell at a reasonable price, you may be forced to ship at a low price considering the storage period, In addition, even if the products provided by the market are left unsold, even if some of them are sold at low prices, it is inevitable that a considerable amount will be disposed of as defective products. This measure was required. The present invention solves the above-mentioned problems (problems) of conventional ones and provides means for extending the storage period of this type of fresh food, etc., and also sells these to the side providing fresh food, etc. It is also an object of the present invention to provide an antibacterial bamboo activated carbon as an effective antibacterial agent, a pack containing the antibacterial bamboo activated carbon, and an appropriate method of using the antibacterial bamboo activated carbon or the pack containing the antibacterial bamboo activated carbon.

[0004]

In order to solve the above problems, the antibacterial bamboo activated carbon of the present invention is made into bamboo pieces by cutting the thick part of the bamboo stem or the entire stem including the epidermis to an appropriate length. Up,
Bamboo powder with a grain size of micro-order to several milli-orders is crushed with a crusher, and after heating this bamboo powder in the range of about 100 ° C to 400 ° C, steam is further sprayed at about 100 ° C to 150 ° C to spray water. A production reaction was generated and manufactured. Further, the pack containing the antibacterial bamboo activated carbon of the present invention is configured by storing the antibacterial bamboo activated carbon manufactured as described above in a pack made of a material having air permeability. Further, as a method of using the pack containing the antibacterial bamboo activated carbon of the present invention, the pack containing the antibacterial bamboo activated carbon is used as a step box.

Used for spraying or adhering to any or all of the cushion sheet, cushion material, intermediate layer paper, cover sheet or the like that is stored to protect the items stored in the box. It may be done.

[0005]

The antibacterial bamboo activated carbon produced by the method of the present invention has an antibacterial activity and a deodorizing activity, and therefore has a function of long-term storage of fresh foods such as vegetables and fruits. Therefore, the pack containing the antibacterial bamboo activated carbon, which is made of breathable material and contains this antibacterial bamboo activated carbon, is packed in a predetermined place (four sides, etc.)
By arranging the required number and number of the above, the above-mentioned antibacterial bamboo activated carbon exerts an antibacterial effect and a deodorizing effect on the fresh food such as vegetables and fruits stored in the corrugated box, because of the air permeability of the pack. In addition to protecting these fresh foods against bacteria, molds, etc. for a long period of time, and promoting the decomposition and prevention of deterioration of freshness due to ethylene, acetaldehyde, etc. generated from the fresh foods, of course, some It also exerts an action of suppressing the diffusion of various fungi that are generated in large quantities from foods with reduced freshness and protecting most foods with good freshness. This is also the case when fresh flowers such as orchids are stored in the corrugated bowl box.
