Description

[Detailed explanation of the invention] (Industrial application field) This invention relates to a water-retaining sheet for fresh flowers, and is useful for transporting fresh flowers to remote areas, carrying flowers on the way home from flower lessons, carrying celebratory flowers, or visiting sick beds. No matter how you hold it, it blocks the heat around the cut end of fresh flowers, provides sufficient moisture, and retains moisture for a long time without causing water leakage. This invention relates to a water-retaining sheet for fresh flowers that maintains its condition.

(Prior Art) Conventionally, water retention means used to keep fresh flowers fresh when transporting them to a remote location include, for example, a test tube-shaped plastic container in the case of high-quality fresh flowers such as orchids. It uses a water-retaining container consisting of a rubber stopper with an insertion opening in the center.Water is poured into the plastic container, the rubber stopper is fitted, and a high-quality fresh flower is inserted into the insertion opening.

Also, in the case of normal fresh flowers, water-absorbing paper such as tissue paper is wetted with water, the paper is wrapped around the stem, and then aluminum foil is wrapped around the paper to retain water. be. Furthermore, in some foreign countries, cotton is wrapped around paper and soaked in water to retain water instead of paper.

(Problem that the invention aims to solve) However, in the former case, there is a problem that if high-quality fresh flowers such as orchids have thick cut ends, it is difficult to carry them around because they cannot be kept in bulk. Since the unit price per piece was high, there was a problem that it was attached to expensive items.

In addition, in the latter case, packaging takes time;
Even if the stems are thick, they can be grouped together, but the cut section, which is the most important part, has a small amount of water retention and often does not fulfill its role, resulting in inefficiency, increased labor costs, and expensive packaging.

Therefore, in view of the above-mentioned problems, this invention was developed to be used when transporting fresh flowers to a remote location, carrying them around on the way home from a flower practice, carrying celebratory flowers, etc., or carrying them around as a visitor to a sick bed. No matter how you hold it, it blocks heat around the cut end of fresh flowers, provides sufficient moisture, retains moisture for a long time without water leakage, keeps fresh flowers, etc. in a fresh state, and is easy to handle. It was devised to provide products at low prices.

(Means for solving the problem) This invention involves adhering a water-retaining layer made of a water-retaining elastic material such as a sponge to one side of a waterproof sheet material, and applying a water-retaining layer to the entire surface of the water-retaining layer or a suitable material. An adhesive layer is arranged at the position, and the water-retaining layer is held in a compressed state with a water-soluble adhesive to form an adhesive, and a release agent layer is provided on the other side of the waterproof sheet material. Furthermore, by forming the waterproof sheet material from aluminum foil, and by forming the waterproof sheet material into a long strip, the above-mentioned problems are solved. .

(Function) The water-retaining sheet for fresh flowers according to this invention is first wrapped and glued around the cut part of the stem of a fresh flower with the side on which the adhesive layer is formed facing the stem, with a part of the water-retaining layer coming off the stem. Then soak this cut part in water.

Then, the water-soluble adhesive that holds and hardens the water-retaining layer in a compressed state will dissolve in the part soaked in water, and the compressed state of the water-retaining layer will be released in the part where the water-soluble adhesive has dissolved. .

As a result, the water-retaining layer expands due to its elasticity and absorbs and retains moisture.

Thereafter, the tip of the portion of the water-retaining layer that has expanded by absorbing moisture is pinched and crushed with, for example, a finger, thereby adhering the inner portion with the adhesive layer and sealing the moisture.

Furthermore, the peeling layer on the other side of the waterproof sheet material allows the water-retaining sheets for fresh flowers to be easily peeled off even when they are stacked one on top of the other.

Furthermore, a waterproof sheet of aluminum foil is used to block the cut end of the stem from heat from the outside.

Furthermore, the waterproof sheet material is used in a rolled-up state in which it can be made into a long belt and pulled out by a required length.

(Embodiment) An embodiment of this invention will be described below with reference to the drawings.

That is, the reference numeral 1 shown in the figure is a water-retaining sheet, and a waterproof sheet material 2 made of aluminum foil, for example.
, a water retaining layer 3 adhesively formed on one surface of this waterproof sheet material 2, an adhesive layer 4 disposed on the surface of this water retaining layer 3, and a water retaining layer 4 disposed on the other surface of the waterproof sheet material 2. It consists of a peeling layer 5.

The water retaining layer 3 is made of, for example, a water-absorbing resin used in diapers or the like, or a water-absorbing elastic material such as cotton or a sponge such as urethane foam.

This water-retaining layer 3 is compressed against its elastic force, and in that state, it is adhered with a water-soluble adhesive such as vinyl alcohol-based water-soluble resin or starch glue, and in that compressed state. Retained.

This adhesion is achieved by soaking the water-retaining layer 3 in a water-soluble adhesive or by spraying an aqueous solution of the adhesive onto the water-retaining layer 3, and then pressing and drying while heating at, for example, 100°C to 120°C. Let them do it. At this time, if necessary, add 10PHR to 30PHR of surfactant to the water-soluble adhesive based on the solid amount of the adhesive.
By blending in a certain proportion, the water-soluble adhesive is made softer and also has better water solubility. Furthermore, the degree of compression at this time is set to, for example, about 1/15 to 1/25 of the thickness in terms of thickness compared to the time of restoration.

Furthermore, the adhesive layer 4 is arranged on the entire surface of the water-retaining layer 3 or at appropriate positions (as shown in the figure, not over the entire surface but in the form of vertical strips at appropriate intervals).

In this case, the reason why the adhesive layers 4 are arranged at appropriate intervals is to improve the water permeability to the water retaining layer 3. If the water permeability is good, the adhesive layers 4 are arranged at appropriate intervals.
They may be arranged over the entire surface, or they may be scattered appropriately instead of in the above-mentioned vertical strip shape, and the form thereof is not limited. Further, although any material may be used for the adhesive layer 4, it is preferable to use a material that is not water-soluble.

On the other hand, the peeling layer 5 provided on the other surface of the waterproof sheet material 2 allows the water-retaining sheets 1 to be peeled off one by one when the water-retaining sheets 1 are piled up. The material is not limited, and if the surface of the waterproof sheet material 2 itself has releasability, the release layer 5 may not be provided. For example, as shown in FIG. 6, this peeling layer 5 can be used when the water-retaining sheet 1 is wrapped in a roll and stored before use, and when it is used, it is pulled out as appropriate depending on the mode of use. It is effective for such things.

Furthermore, by forming the waterproof sheet material 2 into a long belt shape, it is very convenient to handle by winding it up into a roll and pulling it out as appropriate depending on the usage mode.

As shown in FIGS. 3 and 4, the water-retaining sheet 1 thus formed is first applied with a water-retaining layer on the cut portion of the stem 6 of a fresh flower, with the side on which the adhesive layer 4 is formed facing the stem 6 side. With part of the stem 3 detached from the stem 3, the stem 3 is wrapped, for example, about one and a half times and adhered with the adhesive layer 4, and this cut part is immersed in water.

Then, the water-soluble adhesive that holds and hardens the water-retaining layer 3 in a compressed state will dissolve in the water-soaked part, and the compressed state of the water-retaining layer 3 will be released in the part where the water-soluble adhesive has dissolved. be done.

As a result, as shown in FIG.
expands due to its elasticity, absorbs and retains moisture, and at that stage, the adhesive layer 4 is formed by pinching and crushing the tip of the portion of the water-retaining layer 3 that absorbs moisture and expands with, for example, a finger 7. The inner part is bonded to seal moisture.

Thereby, the hollow part of the cut part of the stem 6 is immersed in water, and the water-retaining layer 3 is quickly expanded to fill the hollow part, and the lower part of the hollow part is crushed with fingers, and the stems are glued together using the adhesive part. Since it completely covers the cut surface of step 6 and stores enough moisture, it can be used to transport fresh flowers to remote areas, to carry around on the way home from flower arrangement lessons, to carry celebratory flowers, etc., or to use as a portable device for visiting sick people. No matter how you hold the flower, sufficient moisture can be applied to the cut end of the fresh flower and the moisture can be retained for a long period of time without water leakage.

In addition, the water retaining sheet 1 for fresh flowers according to this invention is as follows:
It goes without saying that the present invention is not limited to the embodiments described above.

(Effect of the invention) In this invention constructed as described above, a water-retaining layer 3 made of a water-retaining elastic material such as a sponge is adhesively disposed on one side of the waterproof sheet material 2, and the surface of this water-retaining layer 3 is An adhesive layer 4 is disposed on the entire surface or at a suitable position, and the water-retaining layer 3 is held in a compressed state with a water-soluble adhesive and adhesively formed, so that the side on which the adhesive layer 4 is formed is attached to the stem 6. The water-retaining layer 3 is wrapped around the cut part of the stem 6 of a fresh flower facing the side, with a part of it detached from the stem 3, and adhered with the adhesive layer 4. When this cut part is immersed in water, the water-retaining layer 3 is compressed. The part of the water-soluble adhesive that is held and hardened in the same state dissolves when immersed in water, and the compressed state of the water-retaining layer 3 is released in the part where the water-soluble adhesive is dissolved.

As a result, the water-retaining layer 3 expands due to its elasticity, absorbs and retains moisture, and at that stage, the tip of the portion of the water-retaining layer 3 that absorbs moisture and expands is pinched off with, for example, a finger 7. By crushing it, the inner part is adhered by the adhesive layer 4 and moisture is sealed.

Therefore, the water-retaining sheet 1 is fixed to the stem 6 of a fresh flower, whether thick or thin, with an adhesive part, and the stem 6 is dipped in water to absorb moisture into the hollow part of the cut end of the stem 6 to quickly expand the water-retaining layer 3 of the water-retaining sheet 1. Fill the cavity and crush the lower part with your fingers so that the adhesive parts adhere to each other, completely covering the cut surface of the stem and storing enough moisture. It is possible to retain moisture for a long period of time without causing any leakage.

Further, the stems 6 are also set with adhesive, and the water retaining sheet 1 can be completely attached to the stems 6 without easily coming off. Since the sides of the stem 6 are set with adhesive, even if water is absorbed, the rate of physical expansion is low, and the cut portion of the stem 6 that requires moisture is not made to thicken the stem 6 wrapped with the water-retaining sheet 1. Only the hollow part of the tube expands quickly and can retain water for a long time.

Moreover, there is little change in volume on the side surfaces of the stems 6, water is absorbed appropriately, and fresh flowers do not lose their vitality. Further, since the side surfaces of the stems do not expand much, even when tying them together into a bouquet, the work of wrapping the water-retaining sheet 1 can be simplified without any difference from the conventional work.

If the waterproof sheet material 2 is made of aluminum foil, it will not spoil the beauty of the bunch of fresh flowers while it is in use, and the cuts of the fresh flowers will block heat, so the fresh flowers can be kept fresh for a long time. This makes it possible to retain the information.

Furthermore, a release layer 4 is provided on the other surface of the waterproof sheet material 2.
Since the water-retaining sheets 1 are arranged, the water-retaining sheets 1 can be peeled off one by one when the water-retaining sheets 1 are piled up, and when the waterproof sheet material 2 is formed of a metal sheet such as aluminum foil. can prevent oxidation even when the aluminum foil that adjusts moisture retention is immersed in water or constantly in contact with moisture, making it susceptible to oxidation, and always maintains a beautiful appearance.

Moreover, if the waterproof sheet material 2 is made into a long strip, it can be used as a tape, and it can be wound up into a roll and pulled out as appropriate depending on the usage, making it easy to handle and very convenient.

Furthermore, since the water retaining sheet 1 is flat, the stems 6
Since the adhesive 4 can be cut and used according to the diameter of the bouquet, it can be cut according to the purpose without waste and is economical.
Apply it in polka dots, stripes, or base grain patterns, etc.
Locally apply the sticky side to the stem and stem cut.
It is also possible to increase the water suction area compared to the cut.

As described above, according to this invention, it can be carried in any way, such as when carrying fresh flowers to a remote location, carrying flowers on the way home from a flower practice, carrying celebratory flowers, or carrying flowers for visiting a sick person. Even when fresh flowers are cut, they can block the heat around the cut edges and provide sufficient moisture, retaining moisture for a long time without water leakage, and keeping fresh flowers etc. in a fresh state.Moreover, it is easy to handle. Moreover, it can be provided at a low cost, and has a practically beneficial effect.
