Description

  The present invention relates to a package for storing coated seeds whose outer peripheral surface is coated with a powder material.

  Coated seeds in which the outer peripheral surface of the seed is coated with a powder material can be sown by a machine, and can greatly reduce the thinning labor, so that it has been sold mainly to farmers so far and widely used. Usually, thousands of these coated seeds are bottled and transported and sold. On the other hand, for home use, few seed grains were needed, and several tens of bare seeds were still put in postcard-sized bags for transportation and sales.

  However, although it is for home use, it is difficult to take out the seeds packed in a bag one by one from the bag, and it has been strongly desired to sell coat seeds for home use.

However, in the coated seed, in order to prevent germination delay, reduction in germination rate, fine root damage, and the like, the coating layer is configured to be easily disintegrated by the expansion of the seed and the absorption of moisture in the soil. For this reason, there is a possibility that the coating layer may be easily broken if the coated seed is transported by bagging as in the prior art. On the other hand, if coated seeds are bottled, cracking of the coating layer can be suppressed, but it is inefficient and expensive to bottle and transport several tens of coated seeds.
JP-A-8-56424

  The present invention has been made in view of such conventional problems. Even when the number of grains is small, the coating layer can be transported and stored in a simple packaging form without cracking the coating layer. Its purpose is to provide a body.

  According to the present invention, there is provided a package for storing coated seeds whose outer peripheral surface is coated with a powder material, the base having a plurality of recesses for storing the coated seeds, and the coated seeds spilling from the recesses. There is provided a package for storing coated seeds, characterized by having a cover member that covers the opening of the recess.

  Here, from the viewpoint of further suppressing cracking of the coating layer of the coated seed, in a three-dimensional orthogonal coordinate system in which the depth direction of the recess is one coordinate axis direction, at least one coordinate axis is formed by the inner wall of the recess and the cover member. It is preferable to regulate the movement of the coated seed in the recess in the direction.

  The depth of the recess may be substantially the same as the diameter of the coated seed. That is, a plurality of coated seeds may be stored in a single flat plane.

  Further, the concave portion may be a hole having an inner diameter slightly larger than the outer diameter of the coated seed. At this time, the depth of the hole is substantially the same as the diameter of the coated seed, that is, it is preferable to store one coated seed in one hole.

  Furthermore, the recess may be a long and narrow groove having a width slightly larger than the outer diameter of the coated seed. At this time, it is preferable that the depth of the elongated groove is substantially the same as the diameter of the coated seed, that is, the coated seed is stored in a row in the elongated groove.

  From the viewpoint of cutting out and using it for the amount of seeding, it is preferable that the base on which a plurality of recesses are formed can be divided between the recesses and the recesses.

  The cover member that covers the opening of the recess so that the coated seed does not fall out from the recess may be an outer packaging bag that wraps the base.

  Alternatively, a sheet member may be used as the cover member, and the sheet member may be attached to the base to seal the opening of the recess. At this time, by using a flexible base as the base, by applying a force from the outside of the bottom surface of the concave portion toward the opening direction of the concave portion, the sheet member is made of coated seeds stored in the concave portion. You may make it take out a tearing coat seed out.

  Furthermore, a lid member is used as the cover member, the lid member is slidable in a plane parallel to the opening surface of the recess, and the lid member is shifted little by little so that a predetermined number of coated seeds can be taken out from the base. Also good.

  In the package according to the present invention, the coated seeds are stored in the concave portion formed on the base, and the opening of the concave portion is covered with the cover member so that the coated seed does not spill out of the concave portion. Even if the amount is small, cracking of the coating layer of the coated seed during transportation and storage is effectively prevented. In addition, the transportation and storage efficiency is much higher than when bottled, and the cost can be reduced.

  Hereinafter, although the package according to the present invention will be described in more detail, the present invention is not limited to these embodiments.

  One Embodiment of the package which concerns on this invention is shown in FIG.1 and FIG.2. FIG. 1 is a perspective view of the package, and FIG. 2 is a vertical sectional view. As can be understood from FIG. 1, the package of this figure includes a base 1 in which a plurality of bottomed holes 12 are arranged at predetermined intervals in the vertical and horizontal directions, and an outer packaging bag (cover) that wraps the base 1. Member) 2. As shown in FIG. 2, the base 1 includes a base main body 11 in which a plurality of through holes 121 are formed, and a sealing material 122 attached to one surface side of the base main body 11. The bottomed hole 12 is formed by sealing one opening of the through hole 121 formed in the base body 11 with a sealing material 122. Of course, a hole shallower than the thickness of the base body 11 may be formed so that the sealing material 122 is not used. The packaging outer bag 2 is substantially similar to the base 1 and has a planar shape that is slightly larger than the base 1, and the flap 22 is outside the one side of the opening / closing opening 24 of the packaging outer bag 2. The sticking agent 23 is applied in a strip shape at the tip.

  As shown in FIG. 2, the inner diameter of the hole 12 formed in the base 1 is set slightly larger than the outer diameter of the coated seed S. The depth of the hole 12 is set slightly deeper than the outer diameter of the coated seed S. As a result, the coated seed S is completely accommodated in the hole 12 through a slight gap from the inner peripheral wall of the hole 12. In order to put the coated seeds S into the respective holes 12 formed in the base 1, for example, the coated seeds S equal to or more than the number of holes are supplied onto the base 1, and the base 1 is vibrated. Thus, the coated seed S may be put into the hole 12.

  After the coated seeds S are stored in all the holes 12, the base 1 is inserted into the bag through the opening / closing opening 24 of the outer packaging bag 2, the flap 22 is folded, and the adhesive 23 is used to flap the outer side of the outer packaging bag 2. 22 is stuck and the entrance / exit opening 24 of the packaging outer bag 2 is closed. Thereby, the outside of the opening of the hole 12 is covered with the outer packaging bag 2, and the coated seed S is prevented from spilling from the hole 12. At this time, the shape of the packaging outer bag 2 is adjusted so that the gap between the packaging outer bag 2 and the opening of the hole 12 is less than the diameter of the coat seed S, more preferably less than the radius of the coat seed S. It is necessary to keep.

  The coated seed S stored in the base 1 as described above is protected by the base 1 from external impacts during transportation and storage, and is also coated by the inner wall of the hole 12 and the outer packaging bag 2. Since the movement of S is restricted, in other words, it is prevented from colliding with or rubbing with other coated seeds S, so that cracking of the coating layer of coated seeds S can be effectively suppressed. When the package according to this embodiment is viewed in a three-dimensional orthogonal coordinate system in which the depth direction of the hole 12 is one coordinate axis direction (xyz coordinate system shown in FIG. 1), the inner wall of the hole 12 and the outer bag for packaging 2 regulates the movement of the coat seed S in the hole in all three coordinate axis directions.

  The hole 12 formed in the base 1 may store fertilizers, agricultural chemicals, and the like necessary for seed growth within a range that does not hinder the storage of the coated seed S. Thereby, the work which applies fertilizer, agrochemicals, etc. separately can be omitted. The fertilizer or the like may be stored in the same hole as the coated seed S, or the fertilizer or the like may be stored alone in a hole different from the coated seed S. Depending on the plant, it is desirable to apply fertilizer after germination and after growing to some extent. In such a case, it is preferable to use a coated fertilizer as the fertilizer stored in the hole together with the coated seed S.

  The material of the base 1 used in the present invention is not particularly limited as long as it can protect the coated seed S from external force, and conventionally known materials such as cardboard, various plastics, and wood can be used. Moreover, if the base 1 is shape | molded, for example with materials, such as a nonwoven fabric and plate-shaped peat moss, and water-soluble paper, the base 1 can be utilized also as a nursery bed. That is, when the base 1 storing the coated seeds S is taken out from the outer packaging bag 2 and immersed in water as it is, it becomes a nursery bed. At this time, an indicator that indicates a state such as moisture or pH may be attached to a portion visible from the outside of the base 1. This makes it possible to easily manage the growth of plants. As the moisture index agent, for example, cobalt chloride or the like can be used. As the pH indicator, litmus paper, BTB, or the like can be used. Further, since the coated seed S is easily affected by humidity, by attaching a moisture index agent to the base 1, it can be used for humidity control of the package during storage and transportation.

  The coated seed S stored in the package of the present invention is not particularly limited as long as the seed surface is coated with a powder material. For example, what coat | covered the surface of a seed using powder material and a water-soluble binder is mentioned. In this case, the seed is put into the coating device, the binder aqueous solution is applied to the surface of the seed by a spray method or the like while rotating the coating device, and then the powder material is introduced to bind the powder and the seed. A coating layer can be formed on the seed surface. By repeating this operation, the thickness of the coating layer can be adjusted. The particle size of the coated seed is usually about 1 to 5 mm, and the particle size and the coating layer thickness may be appropriately determined from the size and shape of the bare seed.

  Examples of the powder material include diatomaceous earth, aluminum hydroxide, barium hydroxide, magnesium hydroxide, calcium sulfate, basic magnesium carbonate, silica, calcium sulfite, calcium carbonate, calcium silicate, illite, halosite, microsite, Vermiculite, peat moss, sand, clay and the like can be mentioned. Examples of the water-soluble binder include starch, PVA, CMC, MC, HPC, and gelatin.

  In the present invention, there is no particular limitation on the target seed, and it can be applied to vegetable seeds, flower seeds, greening / feeding seeds and the like generally used in agriculture and horticulture. For example, cucumbers, melons, pumpkins and other cucurbits, eggplants, tomatoes, petunias, etc., peas, green beans, alfalfa, clovers and other legumes, onions, leeks, etc. Brassicaceae, such as Hanayasai, Habutton, Stock, Alyssum, Seriaceae, such as carrots, celery, etc. Ovalaceae such as Lobelia, Ranunculaceae such as Delphinium, Ganodermaaceae such as Snapdragon, Primula such as Primula, Scarceae such as Begonia, Violet and Pansy and other violets, Eustoma and other gentian, Dent corn, Shiva For example, grass seeds That.

  In FIG. 3, the modification of the package which concerns on the said embodiment is shown. The package of FIG. 3 differs from the package of FIGS. 1 and 2 in that the depth of the hole 12 formed in the base 1 is approximately an integral multiple of the diameter of the coated seed S. That is, in the package of FIG. 3, a plurality of coated seeds S can be stored in one hole 12 (three in FIG. 3). When this is viewed in the three-dimensional orthogonal coordinate system (xyz coordinate system shown in FIG. 1), the movement of the coat seed in the x-axis direction and the y-axis direction among the three coordinate axis directions is restricted by the inner wall of the hole 12. On the other hand, the movement of the coated seed in the z-axis direction is not restricted. However, when the coated seeds of the maximum number of grains that can be stored in one hole (three grains in FIG. 3) are stored, the movement of the coated seeds in the z-axis direction is restricted by the stacked coated seeds, and the coating layer of the coated seeds Is further prevented from cracking and peeling.

  In FIG. 4, the other modification of the package which concerns on the said embodiment is shown. In the package of FIG. 4, a sheet member (cover member) 3 is attached to the entire surface of the base 1 and the opening of the hole 12 is sealed. According to this configuration, the packaging outer bag 2 used in the package of FIG. 1 is not particularly necessary. Of course, the package of FIG. 4 may be further wrapped in the outer packaging bag 2. When the coated seed S is taken out from the base 1, the necessary number of coated seeds S is removed by peeling the sheet member 3 of the hole 12 corresponding to the required number of grains and directing the opening of the hole 12 in the direction of gravity. Only the base 1 can be taken out.

  The package shown in FIG. 5 is a further modification of the package shown in FIG. The package of FIG. 5 is obtained by individually sticking a small sheet member 4 to each opening of the hole 12 formed in the base 1 and sealing it. According to this configuration, a user such as the package of FIG. 4 does not need to devise how to peel off the sheet member, and the necessary number is obtained by peeling off the sheet member 4 of the hole 12 corresponding to the required number of grains. The coated seed S can be taken out from the base 1.

  The package shown in FIG. 6 has a plurality of incisions 14 formed linearly at predetermined intervals between the holes 12 so that a base piece having at least one hole 12 can be separated from the base 1. It is. In such a package, the base piece having the holes 12 corresponding to the required number of grains is cut off from the base 1, the sheet member 3 is peeled off from the cut off base piece, and the coated seed S is taken out. As means for dividing the base 1, conventionally known means such as thinning the thickness of the base of the divided portion can be used in addition to cutting.

  As the sheet member used in the present invention, conventionally known ones can be used, for example, resin films such as polyethylene, polypropylene, acrylic, urethane, and polyester; sheets such as woven fabric, nonwoven fabric, and paper; metal sheets such as aluminum are used. it can.

  The package shown in FIG. 7 uses a lid member 5 as a cover member. That is, the lid member 5 is attached to the surface of the base 1 so as to be slidable in a plane parallel to the opening surface of the hole 12. Specifically, the lid member 5 includes a plate-like top plate 51 having a planar shape identical to that of the base 1, a pair of side plates 52a, 52b suspended from two opposite sides of the top plate 51, and side plates 52a, A pair of claw portions 53a and 53b formed so as to be perpendicular to the side plate and face each other from the lower end of 52b. On the other hand, grooves 15 a and 15 b are formed in the longitudinal direction on the opposite side walls of the base 1. The lid member 5 is slidably attached to the base 1 by engaging the pair of claw portions 53a and 53b of the lid member 5 into the groove portions 15a and 15b of the base 1.

  When the coated seed S is taken out from the base 1, the lid member 5 is slid to release the sealing of the holes 12 in the predetermined row. If the openings of the holes 12 are directed in the direction of gravity, the coated seeds S are spilled only from the released holes 12 in the predetermined row, and the other holes remain sealed with the lid member 5 and thus are not spilled.

  In the embodiment described above, usage instructions, pictures, advertisements, etc. may be printed on the outer surface of the cover member. For example, plant varieties, flowering diagrams, or germinated seedling designs may be printed. Moreover, the holes formed in the base body may be arranged so as to be letters, pictures, or the like.

  FIG. 8 shows another embodiment of the package according to the present invention. 8 differs from the package shown in FIG. 1 in that a plurality of elongated grooves (concave portions) 16 having a width slightly larger than the diameter of the coated seed S are formed in parallel on the surface of the base 1. There is in point. Hereinafter, this difference will be mainly described. As shown in FIG. 9, the groove 16 formed in the base 1 is formed by sealing one opening of the long hole 161 formed in the base main body 11 with a sealing material 162. Of course, a hole shallower than the thickness of the base body 11 may be formed so that the sealing material is not used. The depth of the groove 16 is set slightly deeper than the outer diameter of the coated seed S. Thus, the coated seeds S are stored in a row in the groove 16.

  As described above, when the coated seeds S are stored in all the grooves 16 by a conventionally known method, the outer packaging bag 2 (shown in FIG. 1), the sheet member (shown in FIGS. 4 and 5), the lid member ( The opening of the groove 16 is covered by a cover member such as that shown in FIG. 7, so that the coated seed S is prevented from spilling from the groove 16 of the base 1 during transportation and storage.

  The coated seed S stored in the package as described above is protected by the base 1 from external impact. Further, when viewed in a three-dimensional orthogonal coordinate system in which the depth direction of the groove 16 is one coordinate axis direction (xyz coordinate system shown in FIG. 8), the coating in the z direction and the y direction is performed by the inner wall of the groove 16 and the cover member. Seed movement is restricted, and collision with other coated seeds or rubbing is prevented. On the other hand, the movement of the coated seed in the x-axis direction is not restricted, but if the coated seed S having the maximum number of grains that can be stored is stored in the longitudinal direction of the groove 16, the movement of the coated seed in the x-axis direction by the adjacent coated seeds. And the cracking of the coating layer of the coated seed is further suppressed.

  Also, as shown in FIG. 8, if the end of the groove 16 formed in the base body 11 can be cut off (position indicated by the wavy line in the figure), and an opening is provided at the end of the groove 16, By tilting the base, a plurality of coated seeds S can be continuously sown from the opening at the end of the groove 16 without removing the cover member.

  FIG. 10 shows a modification of the package according to the embodiment shown in FIG. The package shown in FIG. 10 differs from the package shown in FIGS. 8 and 9 in that the depth of the hole 12 formed in the base 1 is substantially an integer multiple of the diameter of the coated seed S. That is, in the package of FIG. 10, the coated seeds S can be stored in several stages in the depth direction of the groove 16 (three stages in FIG. 10). In this case, when viewed in the three-dimensional orthogonal coordinate system (xyz coordinate system shown in FIG. 8), the movement of the y-axis direction among the three coordinate axis directions is restricted by the inner wall of the groove 16, while the x-axis direction The movement of coat seeds in the z-axis direction is not restricted. However, regarding the movement of the coated seeds in the x-axis direction and the z-axis direction, when the coated seed of the maximum number of grains that can be stored is stored in the groove 16, the coated seeds in the x-axis direction and the z-axis direction are coated by adjacent coated seeds. Seed movement is also restricted, and cracking of the coating layer of the coated seed is further suppressed.

  FIG. 11 shows another embodiment of the package according to the present invention. The package shown in FIG. 11 differs from the package shown in FIG. 1 in that a plurality of recesses 17 having a depth slightly deeper than the diameter of the coated seed S are formed on the surface of the base 1. is there. As a result, the coated seeds S are stored in the recess 17 in a single flat plane. When viewed in the three-dimensional orthogonal coordinate system (xyz coordinate system shown in FIG. 11), the movement of the coat seed in the z-axis direction among the three coordinate axis directions is restricted by the inner wall of the recess 17 and the cover member. The movement of the coated seed in the x-axis direction and the y-axis direction is not restricted. However, regarding the movement of the coated seeds in the x-axis direction and the y-axis direction, when the coated seeds with the maximum number of grains that can be stored are stored in the recesses 17, the coated seeds in the x-axis direction and the y-axis direction are coated by adjacent coated seeds Seed movement is also restricted, and cracking of the coating layer of the coated seed is further suppressed.

  FIG. 12 shows still another embodiment of the package according to the present invention. In the package of FIG. 12, a plurality of recesses 18 in which one coat seed S can be stored are formed integrally with the base body 11. And the sheet | seat member 3 is affixed on the surface of the base 1, and the opening of the recessed part 18 is sealed. The base 1 is formed of a deformable material such as plastic, and the sheet member 3 is formed of a material that can be broken by a relatively weak force such as aluminum foil.

  According to such a configuration, when viewed in the three-dimensional orthogonal coordinate system, the movement of the coat seed S in the recess 18 in all three coordinate axis directions is restricted by the inner wall of the recess 18 and the sheet member 3. In addition, cracking of the coating layer of the coated seed S is reliably suppressed. Further, when the coated seed S is taken out from the recess 18, as shown in FIG. 12, force is applied from the outside of the bottom surface of the recess 18 in the opening direction of the recess 18, and the opening is opened by the coated seed S stored in the recess 18. What is necessary is just to tear the sheet | seat member 3 sealed and to take out outside.
