It is what you use. In addition to cut leaves and cut branches other than cut flowers, they can also be used for flower buds such as bulbs, pots, flower seedlings, turf, planted trees, etc. that need water retention during transportation and storage. It is. Further, the present invention is not limited to flowers and can be used for vegetables and other crops that require water retention during transportation.

  The water retention bag 1 for flower buds forms an outer surface 3 made of a liquid-impermeable sheet 2, an inner surface 5 made of a liquid-permeable sheet 4, and a water holding body 6 disposed between the outer surface 3 and the inner surface 5 in a bag shape. doing. The water retaining bag 1 for flower buds is formed by folding the liquid-impervious sheet 2 and the liquid-permeable sheet 4 with the water retaining body 6 interposed therebetween so that the liquid-impervious sheet 2 is on the outside, and overlapping widths. Both ends in the direction are joined to each other by an appropriate means such as a heat seal 7 to form a bag. Therefore, the opening 8 is formed between the end portions 1a and 1a of the water retention bag 1 for flower buds, and the flap-like folded portions 9 that are folded inward are formed at the end portions 1a and 1a, respectively. Yes.

  The liquid-impervious sheet 2 is made of a liquid-impervious material such as polyethylene or polypropylene, and does not leak moisture held in the water holding body 6 or water supplied from the water holding body 6 to the inside of the water retention bag 1 for flowers and the like. belongs to. The liquid permeable sheet 4 is made of a liquid permeable material such as polyethylene, polypropylene, polyethylene terephthalate, rayon, cotton, and the water retaining body 6 is held between the liquid impermeable sheet 2 and supplied from the water retaining body 6. This is for allowing moisture to permeate and supply the inside of the water retaining bag 1 for flower buds. The water-retaining body 6 is made of pulverized pulp, cellulose fiber, natural fiber, hydrophilic fiber made of hydrophilic synthetic fiber, or a superabsorbent resin, or a combination thereof, and absorbs and retains a certain amount of water. Thus, the water supply bag 1 is gradually supplied to the interior of the water retaining bag 1 for flowering plants with a change with time.

  Next, the manufacturing means of the water retention bag 1 for florets will be described. FIG. 5 is a plan view showing a state in which the flower bag 1 is developed, and FIG. 7 is a cross-sectional view taken along the line AA of FIG. As shown in the figure, with respect to the width dimension W of the rectangular liquid-impervious sheet 2, the entire area (W2 × L) surrounded by the length dimension L in the central portion W2 excluding both end portions W1 and W1. The liquid permeable sheets 4 are stacked and arranged. Therefore, the liquid-permeable sheet 4 is not disposed in the both end regions of the liquid-impermeable sheet 2 in the width direction W, that is, the entire area (W1 × L) surrounded by the length dimension L in the both end portions W1 and W1. A water-retaining sheet 6 is interposed between the liquid-impervious sheet 2 and the liquid-permeable sheet 4, and the liquid-permeable sheet 4 is bonded to the liquid-impermeable sheet 2 except for a region covering the water-retaining body 6. 11 (refer FIG. 4, FIG. 7) is joined, and the sheet | seat material 10 is formed.

  As shown in FIG. 5, the water retaining body 6 has a central portion L2 excluding both end portions L1 and L1 of the length L with respect to the inside W3 which is the inner side of the width W2 of the rectangular liquid-permeable sheet 4. It is arranged in the enclosed area (W3 × L2). Therefore, in the whole area (W1 × L) surrounded by the length L of both end portions W1 and W1 of the liquid-impermeable sheet 2, and the central portion W2 where the liquid-impermeable sheet 2 and the liquid-permeable sheet 4 overlap each other. The water retentive body 6 is not arranged in the both end regions (W2 × L1) surrounded by the both end portions L1, L1. If the water retaining body 6 is also adhered to the liquid-impermeable sheet 2 with an adhesive such as hot melt, the water retaining body 6 can be prevented from swinging, and the size of the water retaining bag 1 for flower buds can be reduced. Effective when large.

Next, as shown in FIG. 6, the liquid-impervious sheet 2 and the liquid-permeable sheet 4 at both ends L1 and L1 in the longitudinal direction of the sheet material 10 have a predetermined width. The folded portion 9 that covers the water retaining body 6 from above the liquid permeable sheet 4 is formed by folding back to the liquid permeable sheet 4 side. Further, the sheet material 10 is folded in half at the center in the longitudinal direction so that the liquid-impervious sheet 2 is outside, and the folded portions 9 are overlapped so as to overlap each other, and the width of the overlapped liquid-impervious sheet 2 Both end regions in the direction are thermally welded to each other with a heat seal 7 to form a bag shape. Therefore, an openable flap-shaped folded portion 9 made of a liquid-impermeable sheet and a liquid-permeable sheet is formed in the opening 8 of the water retaining bag 1 for flower buds. The flap-shaped folded portion 9 functions to block water leaking from the water retaining body 6 from leaking from the opening 8.

  Next, the usage method of the water retention bag 1 for flower buds will be described based on FIGS. In use, as shown in FIG. 8, the opening 8 of the water retaining bag 1 for flower buds is opened, and an appropriate amount of water 12 is supplied to the inside. The supplied water 12 passes through the liquid-permeable sheet 4 and is supplied to the water retaining body 6 to be held. Next, as shown in FIG. 9, an appropriate amount of cut flowers 13 to be transported are gathered, and the root portion 13 a is inserted into the interior from the opening 8 of the floral bag 1 and stored. Thereafter, as shown in FIG. 10, the water retention bag 1 for florets is wrapped around the root portion 13a to close the opening 8, and fixed with an appropriate fastening member 14 such as an adhesive tape or a rubber band as shown in FIG. To do. Then, as shown in FIG. 12, it accommodates in the cardboard box 15 for transport, and fixes the predetermined location of the cut flower 13 and the water retention bag 1 for flowers etc. with the adhesive tape 16 etc., and uses for transportation. Note that the moisture 12 may be supplied after the root portion 13a of the cut flower 13 has been inserted into the water retention bag 1 for the floret first.

  During transportation, the water 12 supplied to and held in the water holding body 6 is gradually supplied from the water holding body 6 to the interior of the water bag 1 for flower buds as time passes, so that the root portion 13a of the cut flower 13 is stable. Since the constant moisture 12 is always supplied and maintained in the state, the root portion 13a can be cured while being transported while being retained. Therefore, the freshness of the cut flower 13 can be maintained.

  Since the flower holding water bag 1 is provided with the flap-shaped folded portion 9 at the opening 8, the end 1 a of the flower holding water bag 1 has a double structure, and the opening / closing operation of the opening 8 is facilitated. Moreover, since the folding | returning part 9 is a flap shape, when the quantity of the water | moisture content supplied to the water holding body 6 is too much, or when excess water leaks out from the water holding body 6 because the pressure is applied to the water retention bag 1 for flowers and flowers Since it functions as a stopper for damming it, moisture does not leak out from the opening 8 during transportation or handling, and the cardboard box 15 is not damaged or damaged. Therefore, the worker can efficiently supply sufficient water 12 without paying special attention to the amount of water 12 supplied to the water retaining bag 1 for flowering plants. Therefore, there is no risk of water shortage during transportation, and it is possible to cope with cases where transportation time is long due to traffic congestion or other unforeseen circumstances.

  Using a polyethylene film as the liquid-impervious sheet 2, a polypropylene nonwoven fabric as the liquid-permeable sheet 4, cotton-like pulp and water-absorbing paper as the water retaining body 6, and a synthetic rubber adhesive as the adhesive 11, the dimension of L1 Water retentive bag for flower buds with 30 mm (dimension of the folded portion 9), L2 dimension of 300 mm, W dimension of 240 mm, W2 dimension of 190 mm, W3 dimension of 155 mm, and the weight of the water retaining body 6 of 9 g ± 5% 1 was made. Therefore, the height dimension of the water retaining bag 1 for flower buds formed in a bag shape is 150 mm.

  A water retention bag 1 for flower buds was manufactured in the same configuration as in Example 1 except that the dimension of L1 (dimension of the folded portion 9) was 60 mm.

  Other than L1 dimension (dimension of folded portion 9) 65 mm, L2 dimension 530 mm, W dimension 360 mm, W2 dimension 308 cm, W3 dimension 280 mm, and water retaining body 6 weight 20 g ± 5% Produced the water retaining bag 1 for the florets with the same configuration as in Example 1. Therefore, the height dimension of the water retaining bag 1 for flower buds formed in a bag shape is 265 mm.

[Comparative Example 1]
A water retention bag for flower buds was manufactured in the same configuration as Example 1 except that the folded portion 9 was not provided.

  In order to investigate the relationship between the presence / absence of the folded portion and its size (dimension of L1) and the water retention amount of the water retention body 6, experiments on the maximum water retention amount of distilled water in Example 1, Example 2 and Comparative Example 1 were performed. It was. In addition, the maximum water holding amount is 200 ml of distilled water supplied to the interior of the water retaining bag 1 for the flowers and flowers according to Example 1 and Example 2 and the water retaining bag for the flowers and flowers according to Comparative Example 1, and then 10 ml each. Each time water was supplied, it was laid down horizontally to check for water leakage, and was determined by the amount of water absorbed when water leaked. The results are shown in Table 1.

  As shown in Table 1, it can be seen that, depending on the presence or absence of the folded portion 9, even when the same weight of the water retaining body 6 is used, the maximum water retaining amount is different, and the maximum water retaining amount is increased by providing the folded portion 9. For example, in Examples 1 and 2, the maximum water retention amount is increased by 16% and 36%, respectively, as compared with Comparative Example 1 that does not have a folded portion.

  Next, Gloriosa and Blue Star were used as cut flowers, and an experiment was conducted to examine the effect of the water absorption amount of the water retention bag 1 for flower buds on the fresh weight of the cut flowers after shipment. The cut flower 13 is housed in the refrigerator holding water at a temperature of 10 ° C. by storing the root portion 13a in the water retention bag 1 for flowers and flowers according to the second embodiment, which is supplied with a predetermined amount of water, and fixed with a rubber band as the fastening member 14. The fresh weight retention after a certain period of time was measured with the storage start time as 100%. The results of using Gloriosa as cut flowers are shown in Table 2, and the results of using Blue Star as cut flowers are shown in Table 3. In addition, the state which put the cut flower 13 horizontally on the floor surface of the refrigerator was set as horizontal, and the state set vertically was set as vertical.

  As shown in Tables 2 and 3, as the water absorption amount to the water retaining body 6 increases, the fresh weight retention rate tends to increase, and it can be seen that the freshness can be maintained for a long time. Therefore, by providing the flap-like folded portion 9, even when a sufficient amount of moisture is retained in the water retaining body 6, moisture does not leak from the opening 8 during handling or transportation, and as a result It becomes possible to maintain freshness over time. As a result, the root portion 13a of the flower buds such as cut flowers and the like can be preserved and transported or stored with high freshness, thereby increasing the commercial value. In addition, when the dimension of the folding | returning part 9 made the dimension of L2 / 2 used as the height dimension of the water retention bag 1 for flower buds into the range of 150 mm-265 mm, the preferable result was obtained as 30 mm-65 mm.

As described above in detail, according to the present invention, since it is formed in a bag shape in advance, it is easy to insert the root portion at the time of shipping work, and the shipping work can be performed efficiently. In addition, since the flap-like folded portion is formed in the opening, even when a sufficient amount of moisture is held in the water retaining body, moisture does not leak from the opening during handling or transportation.
In other words, since the water retaining bag for flower buds is equipped with a flap-shaped folded portion at the opening, one end of the water retaining bag for flower buds has a double structure, and the opening and closing operation of the opening is facilitated, and the folded portion is a flap-shaped. Therefore, even if the amount of water supplied to the water holding body is too much, or when excess water leaks from the water holding body due to pressure on the water retention bag for flowers, Moisture leaks out from the opening during transportation or handling, and transport containers such as cardboard boxes for transportation are not damaged or damaged.

  Therefore, it is not necessary to finely adjust the amount of water, and a sufficient amount of water can be supplied quickly. Therefore, since the water supplied to and retained by the water retaining body during transport is gradually supplied from the water retaining body to the interior of the water retaining bag for flower buds as time passes, the root part of the flower buds such as cut flowers is stable. Since a constant amount of water can be constantly supplied in the state, the root portion can be cured while being transported while being kept in water. Therefore, the freshness of cut flowers can be maintained.
