Description

  [Technical Field] The present invention is a technique related to a medium in which general seeds such as plants are stored.

Conventionally, in order to save the trouble of manually spreading seeds in the soil during farming, or to distribute seeds such as plants to a large number of people as a gift for an event, etc. It has been practiced to place seeds such as plants in a recess provided in the material and cover the surface with a thin cover film or the like that can be broken by the germination force of the seeds.
As a patent document, for example, a seed storage sheet is known in which a recess is provided in a cloth material such as paper, cloth, and wood block that easily corrode in the soil, seeds are stored, and the recess is sealed with a coating layer or a cover film. (Patent Document 1).
Also known is a message transmission medium in which plant seeds and plant growth promoting substances are arranged on the surface of a biodegradable material such as paper and a cover film is placed on the surface (Patent Document 2).

In addition, there is known a card in which seeds are arranged at predetermined positions of a card body in order to add value to the card (Patent Document 3).
A card with seeds can function as an original card, but can be cultivated by burying it in the soil when the card is discarded, opening up new uses. . Usually, when seeds are arranged on such a flat plate, a device that discharges seeds from a needle-like nozzle such as a dispenser is used. However, since the card uses a hard material as a base material, when the seed is discharged from the nozzle and placed, the seed may jump out and cause a storage failure. Also, when a card is provided with a recess for storing seeds and the seed is discharged from the nozzle into the recess, the card may jump out of the recess depending on the substrate, the hardness of the seed, etc. .

  Hereinafter, the seed storage medium in the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view of an embodiment of a seed storage medium according to the present invention. In the seed storage medium 1 according to the present invention, a concave portion 3 or a hole 4 is provided as a seed storage portion in a base material 2, a seed storage bag 6 in which seeds 5 are stored is disposed, and this is sealed with a cover film 7. Do it. FIG. 1A is an example of a seed storage medium when the seed storage part is a recess, and FIG. 1B is an example of a seed storage medium when the seed storage part is a hole. .

As the base material, a material having functions and handling properties as a conventional card and having a certain strength, that is, a material having a certain degree of hardness is used. For example, plastic, biodegradable resin, paper, etc. can be used as such, and biodegradable resin and paper are particularly preferable because they are gradually decomposed when buried in soil.
Examples of the biodegradable resin material include biodegradable aliphatic polyesters such as polylactic acid (PLA), polyhydroxyalkanoic acid (PHA), and polybutylene succinate (PBS), and resins.
Examples of paper include general paper and vulcanized fiber. Further, the base material may be one that aromas the scent of flowers. For example, it is possible to make the user more entertaining if the scent of a flower or fruit attached by a plant that germinates from the stored seed is fragrant.

  The size and shape of the substrate are not particularly limited, but the short side is 53.92 to 54.03 mm, the long side is 85.47 to 85.72 mm, and the thickness is 0.76, as defined in JIS standards. You may use the card | curd base material of +/- 0.08mm. However, the shape of the base material in the present invention is not particularly limited to this, and may be designed in a rectangular shape, a square shape, a trapezoidal shape, a star shape, a heart shape, and other free shapes. Further, the substrate may have a single layer structure or a plurality of layers.

  The seed storage unit is a space for storing a seed storage bag in which seeds are stored. Examples of the structure of the seed storage unit include a recess and a hole. The recess can be formed by counterboring the substrate. In addition, when a base material consists of multiple layers, it is also possible to form a recessed part by overlapping the base material which has a through-hole, and the base material without a through-hole. The hole can be formed by punching the base material. However, even if the seed storage portion has a structure other than the concave portion and the hole portion, the seed storage portion is not particularly limited as long as it can store the seed and the polymer absorbent. Further, the size and shape of the seed storage part may be appropriately set depending on the size and amount of the seed and the polymer absorbent to be stored, and are not particularly limited. A plurality of seed storage units may be formed for one seed storage medium.

  The seeds in the present invention refer to seeds or fragments thereof in all plants such as flowers, grass, vegetables, fruits and trees, or mycelial spores, lichen spore, etc., which are stored in the seed storage section. There is no particular limitation as long as it has a possible size, shape, and properties.

In the present invention, since the seed storage bag is used and the seed storage bag in which the seed is stored in advance is arranged in the seed storage portion of the base material, there is no storage defect due to the jumping of the seed during seed filling.
The seed storage bag needs to be a material that is easily decomposed in order to improve the germination rate of seeds when buried in the soil or placed on a hydroponics sponge. Therefore, paper, starch, biodegradable resin, etc. that can be decomposed and dissolved by water or microorganisms are included. Although it does not specifically limit as a material of a seed storage bag, From a viewpoint of an environmental problem, especially biodegradable resin and paper are preferable since they decompose gradually when buried in soil. The seed storage bag can take the form of a net, a woven fabric, a non-woven fabric, a film, and the like. The thickness varies depending on the material, but is preferably several μm to 200 μm.

The seed filling into the seed storage bag is not particularly limited. For example, as shown in FIG. 6, the seed storage bag is fixed to the seed storage bag fixing jig with the insertion opening opened, and a dispenser or the like is used from above. A method of filling seeds and sealing the insertion slot can be used.
The insertion port may be sealed using an adhesive such as a polyvinyl pyrrolidone resin adhesive, or may be sealed by hot pressure or the like as long as the material can be sealed by hot pressure or the like.

In the present invention, the polymer absorbent may be disposed in the seed storage unit or the seed storage bag. A polymer absorber is a material that absorbs and retains moisture and expands. Stable water supply to the seeds is possible due to the function of retaining the moisture of the polymer absorbent. Further, due to the function of swelling, it has an effect of supplying moisture to the cover film and the seed storage bag by contacting the cover film and the seed storage bag, and promoting the swelling and softening of the cover film and the seed storage bag. In addition, by applying pressure to the cover film and the seed storage bag and pushing it out, it also has an effect of helping to destroy and decompose the cover film and the seed storage bag that cannot be completely destroyed by the seed germination force alone. The amount of the polymer absorbent to be stored may be appropriately determined according to the size, amount, ratio, seed size, etc. of the seed.
The polymer absorber may be disposed inside or outside the seed storage bag, but may be disposed outside the seed storage bag and below the seed storage bag as shown in FIG. 4 (a). preferable. In this way, when the seed storage medium is buried in the soil or placed on a hydroponics sponge, the seeds are pushed up while destroying and disassembling the seed storage bag, and the cover film is further destroyed and disassembled. Therefore, it is preferable because it is easy to germinate.

  Specific examples of the material for the polymer absorber include polyacrylic acid polymers, starch polymers, and carboxymethyl cellulose polymers.

The polymer absorbent generally expands to the volume of the absorbed water amount. Moreover, although the amount of moisture absorption varies depending on the material, it is several tens to several hundreds times its own weight. In this experiment, Magic Crystal (manufactured by Matsuno Kogyo Co., Ltd.) was used as a polymer absorber, and when it was buried in the soil, 50 g (about 50 cm ³ ) or more of moisture per gram was absorbed and expanded. Was confirmed.

  The amount of the polymer absorber varies depending on the material and the environment in the soil to be buried, but it is stored in the seed storage part and buried in the soil to absorb moisture, so that it exceeds the thickness of the base material. It is desirable that the amount be expanded. Thereby, it becomes possible to surely help the destruction of the cover film.

  Moreover, in this invention, you may arrange | position a fertilizer in a seed storage part or a seed storage bag. Depending on the fertilizer and cultivar, the fertilizer may directly contact the root and the root may rot, and it is preferable that the fertilizer is placed in the seed storage unit without entering the seed storage bag. Also, depending on the variety, as shown in FIG. 4 (b), a germination promoter is placed in the seed storage bag, and fertilizer is placed outside the seed storage bag in the seed storage section to promote germination and After growing, the roots may be further grown in contact with soil containing fertilizer outside the bag.

  The cover film needs to be provided on one side of the base material in order to seal the concave part when the seed storage part is a concave part, and needs to be provided on both sides of the base material when the seed storage part is a hole. is there.

  In addition, the cover film normally needs to have a certain burst strength in order to reliably seal the seed. However, when buried in soil or placed on a hydroponics sponge, the material needs to be easily destroyed in order to improve the germination rate of seeds. Therefore, paper, starch, biodegradable resin, etc. that can be decomposed and dissolved by water or microorganisms are included. Although it does not specifically limit as a material of a cover film, Since biodegradable resin and paper are gradually decomposed | disassembled when it embeds in soil from an environmental problem viewpoint, it is preferable. Moreover, although the thickness of a cover film changes also with the materials, it is desirable to set it as several micrometers-200 micrometers.

When paper is used as the material for the cover film, the burst strength (kgf / cm ³ {kPa} (10 sheets)) is 0.8 {78} or more (reference: JIS P8112 paper and paperboard mullen low-pressure tester It is desirable that the burst strength test method is used.

  As the paper having the bursting strength, for example, the physical properties equivalent to toilet paper, that is, the water absorption is about 20 (mm) (test time: 1 minute, water temperature: 20 ± 5 ° C., reference: JIS P8141 Paper Krem method It is preferable to use a method that absorbs water and has a property of being easily loosened. However, use those that do not have defects in usage such as unevenness, tearing, and holes.

  In addition, when a biodegradable resin is used as a material for the cover film, it has biodegradability such as polylactic acid (PLA), polyhydroxyalkanoic acid (PHA), polybutylene succinate (PBS), etc. as in the case of the base material. Aliphatic polyesters and resins can be mentioned.

  The shape of the cover film is not particularly limited as long as it has an area sufficient to cover at least the opening of the seed storage portion provided on the base material. For example, when the seed storage portion is a recess, a cover film having an area slightly larger than the area of the opening of the recess may be used as shown in FIG. As shown to a) -2, you may use the cover film which covers the whole surface of a base material. Moreover, as shown to Fig.1 (a) -3, a recessed part may be made into 2 steps | paragraphs shape and you may make it a base material become the same surface of a cover film.

  When the seed storage part is a hole, as shown in FIG. 1 (b) -1, two cover films having an area slightly larger than the area of the opening of the hole may be used. As shown in FIGS. 1 (b) -2 and (b) -3, either one is a cover film having an area slightly larger than the area of the hole, and the other is a cover film having an area covering the entire surface of the substrate. May be used. Furthermore, as shown in FIG. 1 (b) -4, a cover film having an area following the entire surface of the substrate may be used on both sides. Moreover, as shown in FIG.1 (b) -5, after forming a recessed part in the front and back, providing a through-hole in a recessed part and arrange | positioning a cover film in a recessed part may make a base material flush. Good. The shape of the cover film in this invention is not limited to the shape mentioned above, and can be designed suitably.

  In order to seal the seed storage part of a base material, it is necessary to provide the adhesive film 8 in the part which overlaps the peripheral part of a seed storage part at least. Since the adhesive layer contains the seeds and the polymer absorber, it is required that the adhesive layer has an adhesive force that does not peel off from the base material at a normal time before being buried in the soil. Examples of the material for the adhesive layer include starch-based, rubber-based, acrylic-based, urethane-based, and silicone-based materials. Although it does not specifically limit as a material of an adhesive agent, From a viewpoint of an environmental problem, especially biodegradable resin and paper are preferable since they decompose gradually when buried in the soil.

  The bonding of the cover film will be described with reference to FIG. FIG. 2 shows only the case where the cover film has an area slightly larger than the area of the opening of the seed storage unit, but this is the case where the cover film is provided on the entire surface of the substrate. Even if it is provided in any other shape, the same applies.

  First, about the case where a seed storage part is a recessed part, Fig.2 (a) showed some embodiment examples. When sealing a seed storage bag, a polymer absorbent, fertilizer, etc. stored in a recess with a cover film from one side of the substrate, for example, as shown in FIG. 2 (a) -1, a portion corresponding to the periphery of the recess A cover film provided with an adhesive layer can be used. In this case, after storing a seed storage bag, a polymer absorber, fertilizer, etc. in a recessed part, it is good to match a position and to bond a cover film to a base material.

  Further, as shown in FIG. 2A-2, the adhesive layer may be provided on the entire surface of the cover film. In this case, as shown in the figure, when the cover film is bonded to the base material, the seed storage bag, the polymer absorber, the fertilizer, etc. are temporarily fixed to the adhesive layer of the portion corresponding to the recess in advance, You may make it stick this on a base material. By doing so, it is possible to save the trouble of arranging the seed storage bag in the recess, it is possible to improve the production efficiency, and that the polymer absorbent, fertilizer, etc. are not sprayed at the time of bonding It also has an effect.

  Next, some embodiments are shown in FIG. 2B for the case where the seed storage part is a hole. When sealing the seed storage bag accommodated in the hole with the cover film from both sides of the base material, for example, as shown in FIG. A cover film provided with can be used. In this case, a cover film is first bonded to one side of the base material to seal one side of the hole, and the other side of the base after storing the seed storage bag, polymer absorbent, fertilizer, etc. in the hole It is possible to seal by sticking a cover film together.

  Further, as shown in FIG. 2B-2, the cover film on one side is provided with an adhesive layer on the part corresponding to the periphery of the hole, and the other cover film is provided with an adhesive layer on the entire surface. You can also leave. Also in this case, as in FIG. 2 (a) -2, a seed storage bag, a polymer absorbent, fertilizer, etc. are temporarily fixed in advance in a portion corresponding to the hole of the cover film provided with an adhesive layer on the entire surface. In addition, this may be bonded to the base material.

  Alternatively, a cover film having an adhesive layer on the entire surface is pasted on the base material, and after temporarily fixing a seed storage bag, a polymer absorbent, fertilizer, etc. on the adhesive layer from the opposite side of the base material, A cover film may be bonded to the other surface. By doing so, it is possible to prevent the polymer absorber, fertilizer, and the like from being scattered during the manufacturing process. Further, at this time, a layer of polymer absorber, fertilizer, etc. may be formed by laying and temporarily fixing a polymer absorber, fertilizer, etc. on the adhesive layer, and a seed storage bag may be disposed on this layer. .

  Furthermore, as shown to FIG.2 (b) -4, the contact bonding layer can also be provided in the whole surface of the cover film of both surfaces. In this case, a seed storage bag, a polymer absorbent, a fertilizer, or the like may be temporarily fixed in advance to the portions corresponding to the hole portions of the cover films on both sides, and this may be bonded to the base material. Further, if the seed storage bag is temporarily fixed to one cover film and the polymer absorber is temporarily fixed to the other cover film, the manufacturing process may be arranged.

  Moreover, although the method to bond a cover film using an adhesive agent was demonstrated until now, if a cover film consists of a material which has heat-fusibility, you may fuse | melt with a base material using a heating head etc.

  FIG. 3 shows an example of how the seed storage medium is used in the present invention. As shown in FIG. 3, the seed storage medium in the present invention can be effectively used for a SIM card, a mini IC card, a mini magnetic card, and the like that are used by cutting a specific portion from a card-shaped medium.

  In order to cut out the base material, it is necessary to provide a cut-out portion that can be cut out on the base material. The cut-out portion is obtained by half-cutting from one side or both sides, or partially punching out in a broken line shape or the like.

  FIG. 3A shows an example in which the seed storage medium is used for a SIM card. The SIM card has a contact IC module 10 and has the same shape as a normal contact IC card as a whole. By providing a cut-out portion around the contact-type IC module, it is possible to obtain a SIM card that can be inserted into a mobile phone, a USB adapter of a personal computer, or the like. Then, a seed storage unit is provided in a portion other than the portion cut out as the SIM card, and a seed storage bag in which seeds are stored is disposed, thereby providing a seed storage medium.

  FIG. 3B shows an example in which the seed storage medium is used for a mini IC card. The mini IC card shown in the figure includes a non-contact type IC chip 11 and a communication antenna 12 and has the same shape as a normal non-contact type IC card as a whole, but a non-contact type IC chip. Instead of this, a contact type IC module may be provided. By providing a cutout portion around the portion including the IC chip and the antenna, it is possible to obtain mini IC cards having various shapes. In the figure, the mini IC card has a rectangular shape, but is not limited to this. Then, a seed storage unit is provided in a portion other than the portion cut out as the mini IC card, and a seed storage bag storing the seeds is arranged to serve as a seed storage medium.

  FIG. 3C shows an example in which the seed storage medium is used for a mini magnetic card. The mini magnetic card has a magnetic recording unit 13 and has the same shape as a normal magnetic card as a whole. A mini-magnetic card can be obtained by providing a cutout portion in a shape including at least a part of the magnetic recording portion so that it has at least an area capable of communicating with an external magnetic reading device. Further, the shape of the mini magnetic card is not limited to the illustrated one. Then, a seed storage unit is provided in a portion other than the portion cut out as the mini magnetic card, and a seed storage bag storing the seeds is arranged to serve as a seed storage medium.

  In other words, because SIM cards, mini IC cards, mini magnetic cards, etc. use the conventional production line, some of the normal cards are cut out during use and the rest are discarded. It was a problem from the point of view. Conventionally, it is possible to effectively utilize a seed storage bag in which seeds are stored by disposing a seed storage part in a discarded part.
