Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for transporting fresh flowers, etc., and a cool storage sheet for transport.

(Prior Art and Its Division I) In recent years, carnations, roses, chrysanthemums, orchids, etc. have been delivered directly from production areas to consumers, and
Many orchids and the like are imported from foreign countries, and during the transportation process, the above-mentioned fresh flowers transpire water due to breathing, generate respiratory heat, etc., and due to stress caused by vibrations during transportation, etc., they quickly deteriorate during transportation. The quality of the products deteriorated and the value of the products decreased. Therefore, in the past, cold storage agents were placed inside transport containers in order to maintain freshness during transportation, but conventional cold storage agents were liquid or gel-like and packed in a non-porous film, making them difficult to transport. Inside, water droplets form on the surface of the cool storage agent pack, and these water droplets seep into the container, such as the cardboard case, or wet the parchment paper used to wrap the fresh flowers inside, significantly reducing the product value. is the current situation. In addition, conventional cold storage agents are placed into containers in a frozen state, resulting in uneven distribution of cold air inside the container.
There was a problem in that a sufficient freshness preservation effect could not be expected. Furthermore, conventional cold storage agents require pre-cooling in large quantities in a freezer, which poses problems such as an increase in inventory space.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and includes a transportation method capable of transporting fresh flowers, etc. while keeping freshness well, and a cold storage for transportation. The first purpose of this is to provide a cold storage sheet that has been pre-cooled and hydrated with water-absorbing resin sealed inside at least in the upper part of a transportation case that can be filled with fresh flowers, etc. It is fixed and transported.

The second gist is a sheet that can store cold and is used for transporting fresh flowers, etc., in which at least a water-absorbing resin is sealed, and on the side edges of the sheet,
An extension portion is formed that can be fixed to a transportation case or the like.

(Function) When transporting fresh flowers etc. in a transport case, if a pre-cooled cold storage sheet is fixed to the upper part of the transport case, the cold storage sheet will gradually emit cold air during transport.
The inside of the transportation case is kept cool with uniform cold air from the top, so that fresh flowers can be transported smoothly while suppressing blooming, etc.

In addition, a water-absorbing resin is sealed in the cold storage sheet used for transportation in the second aspect, and if the water-absorbing resin is pre-impregnated with water and pre-cooled in a freezer, etc., the water-absorbing resin It exhibits cold storage ability and can effectively supply cold air to fresh flowers, etc. during transportation. In addition, since an extension is formed on the side edge of this transportation sheet, the cold storage sheet can be easily attached to the flap of the transportation case through the extension, and the cold storage sheet can be easily attached to the flap of the transportation case during transportation. It can be easily attached to a transport case to ensure good transport conditions.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a sheet capable of storing cold that is used for transporting fresh flowers, etc., and FIG. 2 shows an enlarged view of the main part of the cross section taken along line A--A of this sheet.

In the figure, the packaging sheet 1 is formed into a single sheet by dividing a large number of bag-like spaces 1a with vertical and horizontal grooves 1b, and is shown in the cross-sectional view of FIG. The water permeable sheet S constituting the front and back parts,
S, are attached to each other at regular intervals to form a groove 1b, and a bag-like space 1a having a considerable space between the grooves 1b and lb is formed, and granular particles are formed inside this bag-like space 1a. A considerable amount of water-absorbing resin 2 is sealed therein.

The one shown in FIG. 2 is constructed by further adhering a waterproof sheet 3 to the surface of the water-permeable sheet S1 on one side.

The water-permeable sheets s, s are made of a sheet material that allows water and air to pass through, and examples of such sheet materials include paper, nonwoven fabric, knitted fabric, and fibrous materials such as cotton. Examples include sheets.

The waterproof sheet 3 is made of a sheet material that does not allow water to pass through, and is made of a plastic sheet such as polyethylene, polypropylene, polyvinyl chloride, or the like. or,
Aluminum foil is sometimes used instead of plastic sheets.

Moreover, as the water-absorbing resin 2 sealed in the bag-like space la,
For example, copolymers of monomers such as hydrolysates of starch-acrylonitrile graft polymers, hydrolysates of cellulose-acrylolitrile graft polymers, and crosslinking agents, such as crosslinked polyacrylamide and its hydrolysates, crosslinked sulfonated polyethylene, crosslinked popal, JP-A-52
Cross-linked vinyl ester-unsaturated carboxylic acid copolymer saponified products, cross-linked polyacrylates and acrylic acid described in No.-14689 and JP-A-52-27455
Examples include acrylic ester copolymers, crosslinked isobutylene-maleic anhydride copolymers, and crosslinked polyethylene oxide.

Further, polymers having self-crosslinking properties, such as self-crosslinking polyacrylic acid, the resin described in Japanese Patent Publication No. 54-30710, and polymers containing at least a hydroxyl group and a carboxylade group in the molecule, such as Japanese Patent Publication No. 54-30710, The resin described in No. 37994 may be used. In addition, starch or cellulose, a water-soluble monomer and/or a monomer that becomes water-soluble upon hydrolysis, and a crosslinking agent are polymerized as essential components, and if necessary, hydrolyzed. It may also be a water-absorbing resin obtained by performing the following steps.

The above-mentioned water-absorbing resin may be used alone or in combination of two or more types, and has a water absorption performance of 20 to 2000.
g/g is preferable, and the shape of the water-absorbing resin 2 is not particularly limited, and may be any shape such as a powdery single particle shape, a flake shape, or a fibrous shape.

For example, as shown in FIG. 3, the packaging sheet 1 configured as described above is attached with staples 4 on the back side of the upper flap 5a on the upper surface side of a flower transportation case 5 into which fresh flowers and the like can be stuffed.
．． It can be used by fixing it through 4 or the like. That is, as shown in FIG. 1, the longitudinal edges of the packaging sheet 1 are integrally formed with extensions 1c and lc that do not have the bag-like space 1a. Drive in staples 4 and 4, respectively, and attach the upper flap 5 of the flower transport case 5.
The packaging sheet 1 can be fixed to the back side of a.

In addition, when fixing the packaging sheet 1 to the back side of the upper flap 5a in this way, it is necessary to soak the packaging sheet 1 in water in advance, and then take it out and pre-cool it in a freezer. permeates into the bag-like space la and is absorbed by the water-absorbent resin 2 inside, and when frozen in this state, the water in the water-absorbent resin 2 is stored cold, and carnations, carnations, etc. If roses etc. are packed and delivered to a home, etc., cold air is gradually emitted from the water-absorbing resin 2 during transportation, and the inside of the flower transportation case 5 can be kept cool.
Quality deterioration during transportation of fresh flowers can be minimized.

In addition, when this packaging sheet 1 is used, the packaging sheet 1
Even if dew condensation occurs on the surface of the flower transport case 5, the internal water-absorbing resin 2 can absorb the condensation water well, and there is no dripping of the condensation water, even if the flower transport case 5 is made of cardboard or the like. Water does not seep into the transport case 5, and a decrease in the strength of the transport case 5 can be minimized.

In addition to the staples 4, the packaging sheet 1 may be fixed to the upper flap 5a using tape such as gummed tape or cloth tape, or may be attached using an adhesive or the like.

Furthermore, if a laminate such as polyethylene laminate, polypropylene laminate, or chlorinated biphenyl film laminate is laid inside the flower transport case 5, the extending portion 1c of the packaging sheet 1 can be thermally welded to the laminate material. When heat-sealing the extension portion 1c to these laminate materials, a separate sealing machine can be used to continuously fix the packaging sheet 1 to the flower transportation case 5, so that it is possible to fix the packaging sheet 1 to the flower transportation case 5 at the time of shipping fresh flowers, etc. It is also possible to create a line.

In addition, in the case where the entire interior of the flower transport case 5 is laminated, the heat insulation effect is extremely good, and
The transportation case 5 also has excellent strength.

In this example, the packaging sheet 1 has a large number of bag-shaped spaces 1.
Since it is in the form of divided packets with a, la, and la, the cold storage agent is not concentrated in some areas, and the cold storage agent is uniformly distributed over the entire area, so that it can be distributed over almost the entire area of the flower transportation case 5. Can supply uniform cold air.

In the case of the packaging sheet 1 as shown in FIG. 2, it is preferable to use the waterproof sheet 3 side in contact with the upper flap 5a.

The packaging sheet 1 can also be used for a transportation case 5 as shown in FIG.
It is possible to use packaging sheets 1 by fixing one each to the back side of each bag 5a, and also by fixing the packaging sheet 1 to the side of the bottom flap 5b.In such usage conditions, freshness can be maintained more strongly. Can be done. In this case, the packaging sheet 1 fixed to the bottom flap 5b side may be hydrated and pre-cooled, but it can also be affixed without being hydrated and pre-cooled. That is, when used in a completely non-hydrated state, even if dew condensation or the like occurs inside the transport case 5 during transportation, the water-absorbing resin within the packaging sheet 1 absorbs this condensation or the like.
Good transportation is possible without water seeping into the transportation case 5, etc., and the packaging sheet 1 on the bottom flap 5b side mainly functions as a moisture absorbent.

Note that although the packaging sheet 1 is shown in the form of a sachet in FIGS. Even in this case, if fixing extensions 1c and lc are formed on both edges, it is possible to securely fix the product to the flap part of the transportation case 5, etc. via these extensions 1c and lc. It is.

Furthermore, the packaging sheet may be formed into a structure as shown in the enlarged cross-sectional view in FIG. 6, and the packaging sheet 11 in FIG.
, B are formed at the same time, and a partition sheet material 14 is disposed in the center, and this partition sheet material 14 can be formed into, for example, a triple structure, and a high melting point material is provided in the center. A linear low density polyethylene layer 14a is formed, and low melting point linear polyethylene 14b, 14 is formed on the front and back sides of the linear low density polyethylene layer 14a.
In addition to the sandwich structure, the partition sheet material 14 can also be formed into a single sheet of low melting point linear polyethylene.

A nonwoven fabric 12 is disposed on one side surface of this packaging sheet 11, and an air permeable plastic film 1 is disposed on the other side.
3 are arranged. The nonwoven fabric 12 is made of, for example, a polyester-nylon spunbond nonwoven fabric or an olefin spunbond nonwoven fabric, and has good water permeability. On the other hand, the air-permeable plastic film 13 is made of low-density polyethylene, vinyl chloride, polycarbonate, polypropylene, nylon, hydrochloric acid rubber 6-vinylon, etc., and has pores that do not allow water to pass through but allow air to pass through. You can keep it.

The partition sheet material 14, the nonwoven fabric 12, and the air-permeable plastic film 13 are heat-welded at predetermined intervals, and the groove portion 11 is
A is formed, and the bag-shaped spaces A and B are formed on the front and back sides, respectively, in the shape of a sachet. For example, water-absorbing polymer 2, silica gel 15, etc. can be sealed in the bag-like space A, and in the bag-like space B on the other side, for example, a life-prolonging agent, a gas adsorbent, an oxygen absorber (iron powder), etc. can be sealed. ), an oxygen generating agent, a carbon dioxide generating agent, a deethyleneizing agent 16, etc. can be sealed.

The packaging sheet 11 formed in this way can be used by disposing a hook in the upper part of the flower transport case 5 in the form of a bridge, for example, as shown in FIG. The extending portion 11C can be attached to the inside of the upper flaps 5a, 5a of the transport case 5 or the inside of the main body of the transport case 5 by means of double-sided tape, heat welding, high frequency sealing, etc. When transporting, for example, if the bag-like space A is located on the bottom side and the bag-like space B is placed on the top side, the water-absorbing polymer 2 in the bag-like space A is hydrated and pre-cooled. In this state, during transportation, cold air is emitted from the water-absorbing polymer 2 into the transportation case 5, and a good cold storage condition can be obtained. Due to the action of the ethylene agent, etc., ethylene gas, carbon dioxide gas, etc. generated within the transport case 5 can be adsorbed well into the bag-shaped space B, and better freshness can be maintained.
