[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for accommodating flowers.

[0002]

2. Description of the Related Art Hitherto, flowers have generally been distributed in a stacked state in a rectangular cardboard box. In addition, there are cases in which a large number of flowers are placed in a large, flower-bottomed cylindrical flower stand. This is because it is necessary to protect the freshness of the flowers and to protect the petals of the flowers because the petals are fragile and easily damaged.

[0003] On the other hand, when selling the flowers, the portion from the lower part of the stem of the flower to the vicinity of the petal is often wrapped with a wrap and then delivered to the purchaser. As described above, the distribution and sale of flowers is extremely troublesome, and it is considered difficult to handle them unless a specialty flower store is available, and the market for flowers has been narrowed. In such a state,
There was also a problem that it was difficult to carry and the flowers were easily damaged.

[0004] From such a viewpoint, in recent years, a long and thin plastic bag is filled with gas to house flowers therein (Japanese Utility Model Laid-Open No. 55-66986, Japanese Utility Model Laid-Open No. 2-8776,
Japanese Patent Application Laid-Open No. 4-279480, etc., or flowers are housed in a firm case that is not deformed by a small external pressure (Japanese Patent Application Laid-Open No. 63-191939, Japanese Utility Model Application Laid-Open No. 3-26705, Japanese Utility Model Application Laid-Open No. 3-87629), and attempts to distribute and sell the product have been made. Recently, in order to maintain the freshness of flowers, the bags have been made of various gas-selective films.

However, even with these methods, the former method of storing flowers in a plastic bag cannot sufficiently protect flowers and plants from external pressure and the like, and the latter method sufficiently protects flowers and plants from external pressure by a case. However, there is a problem that the case is bulky and cannot carry a large amount of flowers at once. In addition, all of these are distributed and sold in a state where flowers are stored in bags, containers, and the like, and in some cases,
Although it is also used for gifts, it is not very good looking for gifts.

[0006]

[Problems to be Solved by the Invention] The present invention has been made from such a viewpoint, and can be easily distributed and sold without damaging flowers, and has excellent decorativeness for gifts. An object of the present invention is to provide a flower wrapping device, and a flower wrapping device capable of controlling the internal oxygen or carbon dioxide concentration and the amount of water vapor (humidity) in addition to these features.

[0007]

SUMMARY OF THE INVENTION In order to solve the above technical problems, the present invention provides a flower wrapping device having the following structure.

That is, the present invention comprises a hollow storage body 2 for storing flowers 6 therein and a bag 4 covering the whole storage body 2, and the storage body 2 has a moisture absorption of 3 to 10%.
Cut out portion 3 is formed of a conductive material, has a circular cross section, and has an outer peripheral surface formed with a cutout 3 facing an internal flower 6, and the bag 4 has an opening 5, and at least the cutout 3 Is sealed, and the inside is sealed by closing the opening 5 ;
When the bag 4 is sealed, the gas concentration inside the packaging tool is
The oxygen concentration is 3-12%, and the carbon dioxide concentration is
Gas that can be controlled to 5-10%
Packaging for flowers, characterized by comprising a selective film
It is.

The housing 2 is for holding the flowers 6 in the packaging 1 and for protecting the flowers 6 from physical obstacles such as external pressure. It is also for giving decorativeness for use.

The shape of the housing 2 is not particularly limited as long as it is strong against external force, for example, a circular cross section such as a cylinder, a cone or a truncated cone. The storage body 2 is formed with a cutout 3 on the outer peripheral surface of the storage body 2 so as to face the internal flowers 6. However, the shape of the cutout 3 is not particularly limited.

The material of the storage body 2 is such that when an external force is applied to the storage body 2, the storage body 2 is deformed so that the notch 3 becomes narrow, and the force can be released. A material having a certain degree of flexibility, for example, cardboard, plastic or the like can be used.

In the flower wrapping device of the present invention, the material of the container 2 has a moderate hygroscopicity, that is, a water absorption of about 3 to 10%.
Since a hygroscopic material having a high degree of hygroscopicity is used, it is possible to prevent excess water vapor released from the flowers 6 from dewing inside the bag 4. If water vapor condenses in the bag 4,
The water droplets formed thereby cause the propagation of various bacteria and reduce the freshness of the flowers 6, and the appearance is not good. In addition, when water droplets adhere to the flowers 6, that portion browns, which causes a reduction in commercial value due to poor appearance.

Meanwhile, the hygroscopicity of the housing body 2 material is too high, floriculture water evaporation is promoted, wilting of flowers and leaves, or Hanakubi may lead to phenomena of freshness decreases such drips. In addition, the water evaporation rate of the flowers, which is preferable for maintaining the freshness, is 10% or less , and more preferably 7% or less . Here, the water evaporation rate of the flower is expressed by the following equation ( 1 ).

[0014]

(Equation 1)

In order to adjust the water evaporation rate to the above range ,
Water absorption represented by the following equation (2) of the housing body 2 is about 3 10%, more preferably Ru der about 3-8%. Book
"Water absorption" as used in the specification, unless otherwise specified
It means the water absorption determined by the following equation (2).

[0016]

(Equation 2)

If the water absorption of the container 2 is less than 3%, it may not be possible to sufficiently prevent the dew of water vapor. On the other hand, if the water absorption exceeds 10%, the water evaporation of the flowers is promoted. In some cases, the strength of the container 2 may be reduced due to water absorption, and the container 2 may be deformed.

The container 2 has a moderate hygroscopicity, that is, a water absorption rate.
In order to impart a hygroscopicity of about 3 to 10% , a method of using a material having an appropriate hygroscopic property, adjusting the thickness of the hygroscopic material, performing a surface treatment on the hygroscopic material, and the like can be mentioned. , May be combined.

/ M ² is more preferred. If the thickness of the paper is more than 400 g / m ² , the hygroscopicity increases, and if it is less than 50 g / m ² , the hygroscopicity is too low and the strength may not be sufficient.

The polymer material having the appropriate hygroscopicity includes acrylic kraft starch resin or
A hard nonwoven fabric impregnated with a crosslinked polyvinyl alcohol, cellulose, a hydrophilic acrylic polymer, or the like, or a plastic sheet is used.

As the surface treatment, at least a part of both sides or an inner surface (a surface in contact with a flower) of the paper material is laminated with a film having a thickness of about 10 to 20 μm using a material having low water vapor permeability. Method. Preferred examples of such a film include polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate. If the entire surface of the paper material is not laminated, it is possible to increase the strength of the paper material by applying a vinyl drawing process such as coating a non-laminated portion with a vinyl chloride resin using a coating machine. Is preferred.

Further, when the paper material is subjected to the above-described treatment to form the housing 2, the outer surface of the housing 2 drawn with a laminate film or vinyl is stuck to the inner surface of the bag 4 to impair the appearance. In order to prevent this, it is preferable that the outer surface of the housing 2 is matted using silica or the like.

The water absorption can be adjusted by performing the above-mentioned laminating process and, if necessary, a vinyl drawing process, so that even when a paper material having high hygroscopicity is used, it is necessary to have a proper hygroscopicity. Can also.

Next, the bag 4 will be described. The bag 4 is used to prevent the flowers 6 from drying during transportation or sale and to maintain an appropriate atmosphere. The material of the bag 4 is at least the cutout 3 so that the flowers 6 can be seen from the outside at the time of sale or the like. Is preferably transparent. The bag 4
Has an opening 5, and the inside is sealed by closing the opening 5. Further, the bag 4 reduces the gas concentration inside the packaging device 1 to the oxygen concentration when the bag 4 is sealed.
About 3 to 12%, and the carbon dioxide concentration

And work is in there).

[0025] The gas selectivity film is is to have a selective permeability coal <br/> acid gas and oxygen as described above, specifically as a wood charge, for example, polysiloxanes, polyolefins , Polydiene, hydrocarbon polymers such as polyacetylene, polyalkylphenyl ethers, polyphosphazenes and the like.

Examples of the polysiloxanes include polydimethylsiloxane, polydimethylsiloxane polycarbonate copolymer, polysiloxane-containing polyurea, and polysiloxane-containing polyamide.

[0027] Examples of the hydrocarbon-based polymers, polymethyl pentene, polymethyl hexene, polybutene, polybutadiene, poly-substituted acetylene, etc. and Porimechirua Lil silane, polymethyl vinyl silane,
Examples include polymers containing alkylsilyl groups such as polymethylsilylacetylene.

Further, examples of the polyalkylphenyl ethers include poly-2.6 dimethylphenyl ether, poly-2.6 diethylphenyl ether and the like.

Examples of the polyphosphazene include polydiethoxyphosphazene, polydi (P-methylphenoxy) phosphazene, and poly N-propyl N′-diethylphosphazene.

The gas-selective film that can be used in the present invention is not limited to these, and films made of the above materials can be used alone or as a mixture, or can be used as a multilayer. The type or configuration of the gas-selective film may be appropriately selected depending on the type of flowers used. In addition, about the manufacturing method,
For example, JP-A-2-275801, JP-A-61-2
No. 16640, JP-A-63-102634, and the like.

Further, it is desirable that the gas-selective film has a gas-permeability and a low water-vapor permeability. Specifically, the water vapor transmission rate at 25 ° C. and 65% RH is preferably 5 g / m ² · 24 hr · atm or less, and more preferably, the water vapor transmission rate is 3 g.
/ M ² · 24 hr · atm or less is more preferable. When a water vapor transmission rate higher than 5 g / m ² · 24 hr · atm is used, the evaporation of water from the flowers may be promoted and freshness may be reduced.

Of the above-mentioned gas-selective film materials, those having such a low water vapor transmission rate include, for example, polypropylene, polyethylene, polyvinyl chloride, and the like.
Examples include polyethylene terephthalate, polyester, polytetrafluoroethylene, and the like.

[0033] In addition, in the flower packaging device 1 of the present invention, the aforementioned
As described above, the storage body 2 is provided with an appropriate hygroscopicity.
Thus, the moisture released from the flowers 6 causes the bags 4
The interior, especially the portion facing the cutout 3 becomes cloudy and flowers 6
Can be prevented from becoming difficult to see, but
The inside of the bag 4 can be made anti-fog treatment as described above.
And preferred . As the anti-fogging processing, for example, kneading a surfactant into the bag 4, the coating such as a surfactant on the inner surface of the bag 4, a general anti-fog hand stages such as applying corona discharge treatment No.

Further, a freshness preserving agent containing, for example, an aqueous solution of silver thiosulfate, an aqueous solution of aluminum sulfate, or an aqueous solution of hydroxyquinoline can be added to the packaging 1 for flowers of the present invention. It is.

As described above, it is necessary to appropriately select the materials of the bag 4 and the storage body 2 in order to adjust the amount of moisture evaporation of the flowers.
And the amount of flowers relative to the type of flowers and the volume of the bag 4 as well as the type of storage, so that the water absorption of the storage 2 after actually storing the flowers in the packaging and closing the opening 5 It is preferable to set the respective materials as appropriate by measuring the water evaporation rate of flowers and flowers.

For the measurement of the water absorption, for example, the container 2 is made of the material whose water absorption is to be measured, and after measuring the weight, the container 2 is put in the bag 4 and the opening 5 is sealed. This is left in a thermostat at 25 ° C., and is taken out after 96 hours, and the weight of the container 2 is measured again. The water absorption is determined by the above equation (2).

The water transpiration rate of the flowers can be obtained by the equation 1 in the same manner as described above.
