Description

  [Technical Field] The present invention relates to a cut flower life prolonging agent for making a cut flower inserted in a vase long lasting.

  Cut flowers inserted in vases deteriorate in a relatively short period of time. This is mainly due to the propagation of germs in the water in the vase where the cut flowers are inserted and adhering to the cut ends of the cut flowers.

  For example, cut flowers arranged in a florist and display cut flowers need to be replaced every time they deteriorate, so it is very beneficial from the viewpoint of reducing running costs to improve the life of cut flowers. .

  Conventionally, in order to improve the endurance of cut flowers, means for changing the water in the vase every day or recutting the stems of cut flowers have been taken, but it is very complicated to perform such means frequently. I can say that.

  In addition, a means of adding a nutrient or a bleaching agent to the water in the vase is also taken, but in such a method, the flower life can be improved for a short period of time (for example, several days of 1 to 3 days). Only.

  Furthermore, by storing the cut flowers in water soaked with a freshness-maintaining material mainly composed of fibrous activated carbon, a means has been developed for keeping the water in the vase clean and thereby improving the flower life. (For example, refer to Patent Document 1 below.)

Japanese Patent Application Laid-Open No. 11-1401

  In the method for maintaining the freshness of cut flowers disclosed in Patent Document 1, it is disclosed that the freshness-keeping agent preferably contains silver (or an inorganic silver compound).

  Activated carbon has an action of adsorbing fine organisms and substances, and silver is known to have a bactericidal action. That is, the freshness maintaining method described in Patent Document 1 keeps water clean by allowing activated carbon and silver to coexist in water existing in the vase.

  However, in order to keep the water in the vase clean for a long period (for example, several weeks or more) simply by coexisting activated carbon and silver, it is necessary to use a considerably large amount of silver. On the other hand, it is difficult to distribute a large amount of silver in a limited space called a vase.

  The present invention has been developed to solve the above technical problem, and in a compact form, the water existing in the vase in which the cut flower is inserted is kept normal for a long period of time, so that the flower of the cut flower can be obtained. An object is to provide a novel life-extending agent for cut flowers that can effectively improve the life.

  In order to solve the above technical problem, the cut flower life-prolonging agent of the present invention is a cut flower life-extending agent used by being immersed in water existing in a vase in which cut flowers are inserted, and the carrier is immersed in an aqueous solution of silver salt. Thereafter, by reduction, a silver active carrier in which a silver film is formed on the surface of the carrier is supported on a base material, or is contained in a container or a bag material (hereinafter, referred to as a feature) This is called “the present life prolonging agent”).

  That is, in the life-extending agent of the present invention, since the silver is supported on the carrier in the form of a film, the amount of silver supported on the unit volume of the carrier is relatively high. In addition, the silver coating carried on the carrier has a porous form with a relatively large surface area, so that the chance of contact with various germs existing in water increases, and the amount of the silver active carrier used is small. However, the water present in the vase can be kept clean for a long period of time.

  In the life prolonging agent of the present invention, a preferred embodiment is one in which the carrier is activated carbon.

  Activated carbon has a very high adsorption capacity, and if this activated carbon is used as the carrier, the adsorption of bacteria on the carrier proceeds with high efficiency. And since the adsorbed miscellaneous bacteria contact the silver which exists in the activated carbon surface one by one, the water in a vase can be effectively kept clean.

  According to the present invention, the water existing in the vase in which the cut flower is inserted can be kept normal for a long period of time, thereby effectively improving the longevity of the cut flower.

FIG. 2 is a cross-sectional view schematically showing a silver active carrier. FIG. 3 is a perspective view showing one usage mode of the life prolonging agent of the present invention.

<Embodiment>
-Invented life prolonging agent 1-
FIG. 1 shows an embodiment of the life prolonging agent 1 of the present invention. The life-extending agent 1 of the present invention has a form in which a silver active carrier 2 is embedded in a bag material 3.

-Catalytically active carrier 2-
FIG. 2 shows the silver active carrier 2. The silver active carrier 2 has a silver coating (Ag) formed on the surface of the carrier 20.

  The carrier 20 is not particularly limited, but it is preferable to use an adsorbent such as activated carbon, silica gel, or zeolite from the viewpoint of efficiently treating germs existing in water. Among them, activated carbon has a particularly high adsorption capacity, and therefore, in the present invention, it is preferable to use activated carbon as the carrier 20. When activated carbon is used as the carrier 20, it is preferable to use coconut shell activated carbon (particularly preferably highly activated coconut shell activated carbon) having a higher adsorption capacity.

-Bag material 3-
The bag material 3 is formed into a bag shape by folding a sheet made of a mixed mesh material of polyethylene terephthalate and isophthalic acid copolymerized polyethylene phthalate and sealing the periphery. Therefore, the bag material 3 has water permeability. The silver active carrier 2 is inherent in the bag material 3.

[Example 1]
-Preparation of silver active carrier 2-
The silver active carrier 2 is prepared by immersing the carrier 20 in an aqueous silver salt solution and then reducing it.

  In this embodiment, highly activated coconut shell activated carbon is used as the carrier 20, and after the carrier 20 is immersed in an aqueous silver nitrate solution (1.0% by weight) for 24 hours, a reducing agent (formaldehyde) is stirred into the aqueous silver nitrate solution. Then, after 3 hours, the carrier 20 was pulled up, washed with water and dried (110 ° C., 15 hours) to obtain the silver active carrier 2.

  By providing 0.3 g of the obtained silver active carrier 2 in the bag material 3, the life-extending agent 1 of the present invention according to Example 1 was obtained.

[Comparative Example 1]
The activated carbon agent which concerns on the comparative example 1 was obtained by making 0.3 g of highly activated palm pattern activated carbon (what silver is not carry | supported) contained in the said bag material 3. FIG.

-Life extension test of cut flowers-
As shown in FIG. 3, after putting the life-extending agent 1 of the present invention into the vase 10, 200 ml of water was added and cut flowers 100 were inserted. In this test, the cut flowers 100 were examined for three types of buds, roses, and gerberas.

  In this state, it was left under a temperature condition of 25 ° C., and the turbidity of water and the state of each cut flower 100 (flower holding period) were observed over time. During this test, water was added by the amount lost by evaporation. The same test was performed on the activated carbon agent of Comparative Example 1. The results are shown in Table 1 below.

  From the results shown in Table 1 above, when the life-extending agent 1 of the present invention is introduced into the water in the vase 10 (Example 1), the water in the vase 10 does not become turbid for a long time, and the vase 10 It was confirmed that the cut flower 100 inserted in the slab was kept sufficiently fresh for a long period of time.

  On the other hand, in the life extension test conducted for Comparative Example 1, it was confirmed that the water became cloudy and the cut flower 100 deteriorated in a short period after two days had passed since the start of the test.

  By the way, in this example, as the life-extending agent 1 of the present invention, the silver active carrier 2 having a form in which the silver active carrier 2 is embedded in the water-permeable bag material 3 is used. Instead of the bag material 3, the silver active carrier 2 may be incorporated in a container having water permeability.

  Further, the life-extending agent 1 of the present invention may be in a form in which the silver active carrier 2 is supported on a substrate such as cloth or paper.

  It should be noted that the present invention can be implemented in various other forms without departing from the spirit or main features thereof. Therefore, the above-mentioned embodiment is only a mere illustration in all points, and should not be interpreted limitedly. The scope of the present invention is indicated by the scope of the utility model registration request, and is not restricted by the text of the specification. Further, all modifications and changes belonging to the equivalent scope of the claims for utility model registration are within the scope of the present invention.
