BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive sheet for plants. In detail, when transporting plants to a remote location, for example, transporting fresh flowers from the production farm to the market, celebratory flowers, etc.
When used as a portable device to carry around when visiting a sick person, 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 leaking water. The present invention relates to a pressure-sensitive adhesive sheet for plants that can keep fresh flowers and the like in a fresh state.

0002

BACKGROUND OF THE INVENTION Conventionally, water retention means used to keep plants fresh when transporting them to remote locations include test tube-shaped plastic containers, for example, in the case of high-quality fresh flowers such as orchids. A method is used in which a water-retaining container consisting of a rubber stopper with an insertion opening cut out in the center is used, the plastic container is filled with water, the rubber stopper is fitted, and fresh flowers are inserted into the insertion opening and held.

[0003] 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 aluminum foil is further wrapped on top of the paper to retain water. It is something. Furthermore, in some cases, instead of tissue paper, cotton is wrapped and soaked in water to retain water.

0004

[Problem to be Solved by the Invention] However, in the case of the former, there is a problem that if the high-quality fresh flowers such as orchids have thick cuts, it is difficult to carry them around because they cannot be packed in large numbers. Since the unit price per piece was high, there was a problem that it was attached to expensive items. In the latter case, it takes time to wrap the stems, and even if the stems are thick, they can be packed together.
The amount of water retained in the cut section, which is the most necessary, is often small and the water retention rate is often not fulfilled, resulting in inefficiency, increased labor costs, and expensive packaging.

[0005]

[Means for Solving the Problems] In view of these problems, the present inventors have conducted intensive research and have developed a water-retentive material such as a sponge that can be sufficiently impregnated with water and water containing nutrients. By combining it with a waterproof sheet that has adhesive, it is easy to handle, and it is a simple operation that blocks heat around the cut edges of fresh flowers and provides sufficient moisture no matter how you hold them. They discovered that it can retain moisture for a long period of time without causing water leakage, and can keep flowers, etc., fresh.

[0006] The present invention provides an adhesive for plants, characterized in that an adhesive layer is provided on at least the peripheral edge of one side of a waterproof sheet, and a water-retentive material is provided on at least the portion of the same side excluding the peripheral edge. It is a sheet.

[0007] Furthermore, the present invention impregnates the water-retaining material of the pressure-sensitive adhesive sheet for fresh flowers with water or water containing nutrients, places a cut end of a plant, etc. on the water-retaining material, and folds the pressure-sensitive adhesive sheet. , is a method of preserving plants in which the peripheral parts are joined together using adhesive layers.

[0008]

[Function] The waterproof sheet constituting the pressure-sensitive adhesive sheet for plants of the present invention may be made waterproof by bonding a plastic film or metal foil to at least one side of paper, etc., as well as plastic film and metal foil such as aluminum foil. You can also use sheets etc. Of course, printing or the like may be applied.

The adhesive layer is provided on at least the peripheral edge of one side (waterproof side) of the waterproof sheet. As the adhesive, rubber-based, acrylic-based, vinyl ether-based, and other adhesives that are commonly used in adhesive sheets can be used.

[0010] The water-retaining material is not particularly limited as long as it can sufficiently retain water or water mixed with nutrients, and for example, sponge or non-woven fabric can be used. In addition, when using it, it is preferable to use a material with high cushioning properties that has high adhesion to stems, cut ends, etc. The water-retaining material is bonded to the above-mentioned waterproof sheet at a position other than the periphery. The bonding may be performed through an adhesive layer, but a method such as heat bonding may also be used. Among these, it is preferable to provide an adhesive layer over the entire one side of the waterproof sheet and to bond the water-retentive material to the entire area except for the peripheral edge through the adhesive layer, since this allows efficient production. Note that dry nutrients, medicines, etc. may be attached to the water-retentive material in advance.

[0011] In order to protect the adhesive layer and the water-retaining material, it is preferable to attach a release sheet to the adhesive layer. As a release sheet, sheets of glassine paper, film laminated paper, etc.
Those provided with a release agent layer such as silicone resin or fluororesin can be appropriately selected and used.

The pressure-sensitive adhesive sheet for plants of the present invention is prepared by first impregnating a water-retaining material with water or water mixed with nutrients, and placing a fresh flower or the like so that the cut end thereof is approximately in the center of the water-retaining material.
By folding the adhesive sheet from the center and joining the peripheral parts with the adhesive layers, the heat around the cut end is blocked and moisture is sufficiently supplied, and the impregnated water retains moisture for a long period of time without leaking. It is possible to keep fresh flowers etc.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view of the pressure-sensitive adhesive sheet for plants of the present invention. The pressure-sensitive adhesive sheet 1 for plants includes a pressure-sensitive adhesive layer 3 on one side of a waterproof sheet 2, and a water-retaining material layer 4 retaining water or water containing nutrients on top of the pressure-sensitive adhesive layer 3. Also,
FIG. 2 is a diagram for explaining a cross section taken along line AA in FIG.

[0014] This pressure-sensitive adhesive sheet for plants can be made by, for example, impregnating a water-retaining material with water or water mixed with nutrients, and placing the tip of a stem of a fresh flower on approximately one half of the water-retaining material 4 (FIG. 3).
It can be attached by folding this adhesive sheet in half and pressing and adhering the overlapping adhesive layers at the peripheral edges (FIG. 4). 5 and 6 are diagrams illustrating a case where a plurality of fresh flowers are attached. In this case, it can be rolled up and carried as shown in FIG. Moreover, it is also possible to attach a plurality of fresh flowers as shown in FIG. In the pressure-sensitive adhesive sheet for plants of the present invention, it is preferable to protect the pressure-sensitive adhesive layer and the water-retaining material using a release sheet as shown in FIG.

[0015]

[Effects of the invention] The pressure-sensitive adhesive sheet for plants according to this invention is:
Since you only need to pinch the tip of the stem, you can work extremely efficiently. ■Even after it is attached to a plant, the adhesive layer keeps the periphery in close contact, so there are no problems such as water leakage. ■Can also be used for multiple plants. It has the following advantages.
