Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging tool for storing flowers.

[0002]

2. Description of the Related Art Conventionally, flowers have generally been stored in a rectangular cardboard box in a laminated state and distributed. In addition, it may be distributed even in a state where a large number of flowers are placed in a large flower stand with a bottomed cylinder. This is to maintain the freshness of the flowers, and because the petals of the flowers are fragile and easily damaged, it is necessary to protect them.

On the other hand, at the time of sale, the lower part of the flower stem to the vicinity of the petals are often wrapped with paper or a plastic film and then handed to the purchaser. As described above, distribution and sales of flowers are extremely troublesome, and it is difficult to handle them unless they are a flower shop, and the market for flowers is narrowed. In addition, in such a state, it is difficult for the purchaser to carry even after the purchase, and there is a problem that the flower is not sufficiently protected from external pressure and the flower is easily damaged.

From such a point of view, in recent years, a long and slender vinyl bag is filled with gas and flowers are stored therein (Japanese Utility Model Publication No. 55-66986, Japanese Utility Model Publication No. 2-8776,
(Japanese Unexamined Patent Publication No. 4-279480, etc.), or the flowers are housed in a solid case that is not deformed by a slight external pressure (Japanese Unexamined Patent Publication No. 63-191739, Japanese Utility Model Laid-Open No. 3-26705, Japanese Utility Model Laid-Open No. No. 3-87629, etc.), distribution and sales have been attempted. Further, recently, in order to maintain the freshness of the flower, there have been some cases where the bag is made of various gas selective permeable films.

However, even if these methods are adopted, the former method of storing the flowers in a plastic bag cannot sufficiently protect the flowers from external pressure and the like, and in the latter method, the flowers are sufficiently protected from the external pressure due to the case. There is a problem that the case is bulky and cannot carry a large amount of flowers at one time. In addition, all of these are items that are distributed and sold in the state that the flowers are stored in bags, containers, etc., and in some cases, they are also used for gifts, but they are not very useful for gifts. It doesn't look good.

[0006]

The object of the present invention is made from such a point of view, and it can be easily distributed and sold without damaging the flowers, and is excellent in decorativeness as a gift. It is a wrapping tool for flowers and forms a desirable oxygen and carbon dioxide concentration atmosphere for keeping the freshness of the flowers for a long time, and supplies products that do not cause flower damage and wilt. By supplying the minimum amount of oxygen necessary for survival and keeping the flower in a hibernating state, it suppresses nutrient decline and wilting, which are obstacles in high oxygen, and suppresses the progression of flowering. By controlling the amount, it is necessary to improve the appearance of flowers and to suppress the generation of various bacteria due to dew condensation.

[0007]

In order to solve the above technical problems, the present invention has a flower wrapping tool having the following structure.

That is, the present invention comprises a hollow container 2 for accommodating the flower 6 inside, and a bag 4 for covering the entire container 2, the container 2 having a circular cross section and having an outer peripheral surface thereof. A wrapping tool 1 for flowers, characterized in that a notch 3 is formed so as to face the flower 6 inside, and the bag 4 is a thing whose inside is sealed like closing the opening 5.
Is.

The container 2 holds the flower 6 in the packaging 1, and protects the flower 6 from physical obstacles such as external pressure. It is a product for giving decorative properties.

The shape of the housing 2 is not particularly limited as long as it has a strength against external force and has a circular cross section such as a cylindrical shape, a conical shape, or a truncated cone shape. Also,
A notch 3 is formed on the outer peripheral surface of the storage body 2 so as to face the internal flower 6. However, the shape of the notch 3 is not particularly limited.

The storage body 2 for storing the flower of the present invention is preferably made of a material having strength in order to protect the flower from external pressure, and examples thereof include a material having a certain degree of flexibility such as cardboard and plastic.

Further, by using a material having an appropriate hygroscopic property as the material of the container 2, it is possible to prevent the bag 4 from being condensed inside due to the water evaporated from the flower. Condensation on the inner surface of the bag causes the propagation of various bacteria, which reduces the freshness of the flowers, and when it becomes difficult to see from the outside, the product becomes less commercial.
Further, when the water droplets adhere to the flower 6, the portion of the flower 6 is browned, resulting in poor commercial appearance due to poor appearance.

On the other hand, if the hygroscopicity of the storage bag is too high, water evaporation from the flowers is promoted, causing wilting of the petals and leaves. Therefore, the water evaporation rate of the flower is preferably 10% or less, more preferably 7%. % Or less is more preferable. The water evaporation rate of the flower is
It is represented by the following formula (1).

[0014]

(Equation 1)

In order to adjust the water transpiration rate to the above range, the water absorption rate of the container 2 represented by the following formula (2) is preferably about 10% or less, more preferably about 3 to 8%. .

[0016]

(Equation 2)

If the water absorption rate of the container 2 is less than 3%, it may not be possible to sufficiently prevent the condensation of water vapor.
When the content is 0% or more, the freshness of the flowers is deteriorated, and depending on the material of the container 2, the moisture is absorbed and the strength is deteriorated, so that the flowers cannot be protected from an external force during transportation.

In order to make the storage body 2 have an appropriate hygroscopicity, a material having an appropriate hygroscopicity is used, the thickness of the hygroscopic material is adjusted, and the hygroscopic material is subjected to a surface treatment. May be increased and these may be combined.

For example, as a material having an appropriate hygroscopic property, a paper material, a hygroscopic polymer material and the like are listed.
Preferably, the amount of paper material having a low water absorption can be increased. Examples of such paper materials include waterproof paper, ivory-based and card-based materials using virgin pulp, and the thickness is preferably 50 to 400 g / m ² , and 100 to 350.
g / m ² is more preferable. When the thickness of the paper is more than 400 g / m ² , the hygroscopicity is high and the workability when loading it into the flower packaging bag is deteriorated. When it is less than 50 g / m ² , the hygroscopicity is too low and the strength is insufficient. is there.

Examples of the polymer material having appropriate hygroscopicity include acrylic kraft starch resin, hard non-woven fabric impregnated with cross-linked polyvinyl alcohol, cellulose, hydrophilic acrylic polymer, or plastic sheet.

As the surface treatment, at least a part of both surfaces or the inner surface (the surface in contact with the 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. The method is raised. Preferred examples of such a film include polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate. When the entire surface of the paper material is not laminated, the strength of the paper material can be increased by applying vinyl drawing processing to the non-laminated area by coating it with vinyl chloride resin using a coating machine. It is preferable above.

In the case where the paper material is subjected to the above-mentioned treatment to form the storage body 2, the outer surface of the storage body 2 which has been laminated or laminated with vinyl is attached to the inner surface of the bag 4 to impair the appearance. Therefore, in order to prevent this, it is preferable that the outer surface of the housing body 2 be matted with silica or the like.

Since the water absorption rate can be adjusted by performing the above-mentioned laminating process and vinyl drawing process if necessary, it is necessary to give a proper water absorption property even when a highly water-absorbent paper material is used. You can

Next, the bag 4 will be described. The bag 4 is intended to prevent the flower 6 from drying during transportation and sale and to maintain a proper atmosphere. The material of the bag 4 is from the outside when the flower 6 is sold.
Is visible, it is preferable that at least the portion facing the cutout portion 3 is transparent. Also, the bag 4 is
The bag has an opening 5, and the inside is sealed by closing the opening 5. When the bag is sealed, the oxygen and carbon dioxide gas concentrations inside the bag 4 can be controlled. If 4 is made of a perforated synthetic resin film, an atmosphere suitable for keeping the freshness of the flower can be formed.

The open area ratio of the perforated synthetic resin film used in the present invention is 1 × 10 ^-6 to 1 × 10 ^-5 %, and the surface area inside the bag is 300 to 5000 cm ² per 100 g of flowers.
And the average pore diameter of the film is 20 μm to 150 μm.
It is preferable that the number of the holes is plural per one packaging bag. The perforated film used in the present invention may be any as long as it can be used for packaging flowers, but generally, unstretched polypropylene, stretched polypropylene, polyethylene, polyvinyl chloride, Etc. are used, but other films such as polyamide, polyester, polycarbonate, polystyrene, etc., and composite films of these may be used.Furthermore, a film provided with a sealant layer on the surface of these films may also be used. There is no problem even if the film is clouded. Further, the thickness of these films is usually 20 to 50 μm, and there is no problem even if the surface is printed.

In the bag using the perforated film of the present invention, the open area ratio is determined by the weight of the flowers to be packed,
The open area ratio must be 1 × 10 ⁻⁶ to 1 × 10 ⁻⁵ %. The reason for this is to keep the amount of oxygen and the amount of carbon dioxide in the packaging bag under conditions suitable for keeping the freshness of the flower. From the results of experiments conducted by the present inventors, it was found that the oxygen concentration was 3% or more and 15% or less. Desirably, the opening area ratio for satisfying these conditions is 1 × 10 ⁻⁶ to 1 × 10 ⁻⁵ %. If the open area ratio is 1 × 10 ⁻⁶ % or less, the flower will become anoxic during the distribution process due to the respiratory action after packaging, and will start anaerobic breathing, and the flower will rot. If the open area ratio is 1 × 10 ^-5 % or more, the oxygen content in the packaging bag becomes too large, the respiratory action of the flower becomes active, and the flower grows more than necessary and the nutrients are exhausted and withered. There is a problem that the product is lost or loses commerciality due to overblooming. Therefore, it is necessary that the aperture area ratio of the perforated film used as a packaging bag for a flower is 1 × 10 ⁻⁶ to 1 × 10 ⁻⁵ %, preferably 4 × 10 ⁻⁶ to 8 × 10 ^−. It is more effective to be ⁵ %, particularly preferably 5 × 10 ^{−6 to} 9 × 10 ⁻⁶ %.

It is desirable that the average diameter of the holes in the perforated film is as small as possible.
˜150 μm, preferably 30 to 100 μm. It is desirable that the pore size is as small as possible, but 20μ
When it is less than m, the productivity of the perforated film is lowered. If the average pore size is 150 μm or more, the number of holes required to obtain an appropriate ratio of the open area decreases, and the quality accuracy of maintaining the freshness becomes uneasy. The shape of the hole may be any shape such as a circle, a square or a triangle, and any shape may be used as long as the average diameter in the major axis direction is 150 μm or less. More desirable.

The number of holes per bag of the perforated film used for the flower packaging bag is calculated from the open area ratio and the average hole diameter, but it is desirable to use a plurality of holes as much as possible.
A plurality of holes are preferable to ensure freshness because the holes may be blocked by adhesion of contents or external conditions such as attachment of a label table.

The size of the flower packaging bag, should bag surface area per flower 100g is 300～5000Cm ^2, preferably 500~3000cm ^2. The inner surface area of the bag is specified so that the seal portion, that is, the binding margin is not included in the calculation. Flower 100
If the surface area in the bag is less than 300 cm ² per gram, the density of the flowers in the bag will be high and oxygen deficiency will result, causing anaerobic breathing, which is not preferable. Further, when the surface area in the bag per 5000 g of flower is more than 5000 cm ^2, the density of flower in the bag is low, the initial oxygen amount in the bag is high, and the oxygen supply amount is large in the above-mentioned opening area ratio. Respiratory action becomes active and withers easily, and the nutrients of the flower itself are exhausted.

Although it is not limited to the packaging of flowers,
To maintain the freshness of fruits and vegetables, of course,
And the temperature control at the store is an important point,
Naturally, the respiration rate and water evaporation rate of the flower depend on these temperatures, and both increase as these temperatures increase, but the present invention assumes these temperatures to be 3 to 30 ° C.

Further, it is desirable that the film have a low water vapor transmission rate. Specifically, 25 ° C, 65% R
It is preferable that the water vapor permeability in H is 5 g / m ² · 24 hr · atm or less, and further the water vapor permeability is 3 g / m ^2.
Those having m ² · 24 hr · atm or less are more preferable. If a material having a water vapor transmission rate higher than 5 g / m ² · 24 hr · atm is used, moisture evaporation of the flower may be promoted, resulting in a decrease in freshness.

Examples of such a film material include polypropylene, polyethylene, polyvinyl chloride,
Examples thereof include polyethylene terephthalate, polyester, polytetrafluoroethylene and the like.

In the flower wrap 1 of the present invention, the moisture released from the flower 6 prevents the inside of the bag 4, particularly the portion facing the notch 3 from being clouded and making the flower 6 hard to see. In order to open the bag, it is preferable that the inside of the bag 4 is antifogging processed. Examples of the antifogging process include general antifogging means such as kneading a surfactant into the bag 4, coating the inner surface of the bag 4 with a surfactant, corona discharge treatment, and the like. As described above, it is possible to give the storage body 2 hygroscopicity.

As described above, it is necessary to properly select the materials of the bag 4 and the container 2 in order to adjust the water evaporation amount of the flower, but the water evaporation amount of the flower is
Also, the water absorption rate of the container 2 after the flower 5 is actually stored in the packaging and the opening 5 is closed is different not only by the type of the container but also by the type of the flower and the amount of the flower with respect to the volume of the bag 4. It is advisable to select each material as appropriate by measuring the water evaporation rate of the flower and the flower.

The water absorption can be measured, for example, by making the container 2 from the material for which the water absorption is to be measured and measuring its weight,
It is placed in the bag 4 and the opening 5 is sealed. This is put in a constant temperature and humidity chamber at 25 ° C. and left to stand, and after 96 hours, it is taken out and the weight of the container 2 is measured again. The water absorption rate is obtained by the above-mentioned equation 2.

The water transpiration rate of the flower can be calculated in the same manner as the above equation.

[0037]

With the use of the flower wrapping tool 1 of the present invention, the flower wrapping 6 as a whole is housed in the bag body 4 having a circular cross-section having strength against external pressure and having the notch 3. Since it is packaged, the flower 6 can be protected from physical injury from the outside during transportation and sale, and
You can also keep the freshness of the flowers.

By combining the container 2 and the bag 4 with each other, it is possible to use as a flower wrapping tool which is excellent in decorativeness and suitable for gifts without impairing the image that a purchaser would normally hold in a bouquet. You can

By the above action, the flowers can be completely packaged, and can be distributed and sold without damaging the flowers, and can be easily sold by the vending machine, and they are good-looking as gifts. It becomes a thing.

Further, if the bag 4 is made of a synthetic resin film having a hole and is sealed, the oxygen concentration and the carbon dioxide concentration in the packaging tool 1 can be adjusted to those suitable for storing the flower 6 during distribution. In addition, if the container 2 is made of a material having an appropriate water absorption, the water vapor (humidity) in the packaging tool 1 can be controlled, so that the reduction in the commercial value of the flower 6 can be further suppressed. it can.
