Description

  The present invention does not require adhesives or fasteners, can be easily assembled in the field, and requires a minimum amount of space for transportation and storage because it is a piece of paper prior to assembly. The present invention relates to an integrally assembled polygonal planter pot.

  Conventionally, planter pots have been made of synthetic resin, wood and earthenware.

  Recently, seedling pots and flower pots using paper have been proposed.

  For example, Patent Document 1 discloses a paper folding flower pot in which a side plate is bent and both edges are bent and joined at the meeting portions at both ends thereof, and a bottom plate is attached to the side plate. In the case of this flower pot, since it is a paper material that requires an adhesive and can be bent into a cylindrical shape, sufficient strength cannot be obtained.

  Patent Document 2 discloses a paper-embedded bottom flower pot in which a bottom plate is fitted from above with a pyramidal cylindrical shape narrowed down. This flower pot is composed of two members, and the pyramid-shaped cylindrical portion is bonded with an adhesive.

  In Patent Document 3, a plurality of fan-shaped strips of paper are wound into a roll shape, overlapped in layers, and bonded and bonded to both sides, the lower edge of the cylindrical body is rounded inward to form a ring-shaped convex portion, and A paper flowerpot in which a disk-shaped bottom plate is placed on the link-like convex portion is disclosed. Also in the case of this flower pot, an adhesive is used, the formation of the ring-shaped convex part is complicated, and it is composed of two members.

  In these conventional techniques, there is no convenience that the user can easily assemble and use, and there is a problem that a large volume of the finished product must be handled when transported from the manufacturer to the user. is there.

  In Patent Document 4, a wall portion constituting the outer periphery of a flower pot and a reinforcing portion similar to the wall portion are fitted, and a bottom portion having a flat portion and a bent portion is connected to the bent portion between the wall portion and the reinforcing portion. A paper flower pot sandwiched between is disclosed. This flower pot is composed of three members, and the wall and reinforcement are made of paper tubes. The assembly can therefore be performed by the user, but has the disadvantage that it requires a transport space of equal or greater volume than the finished product when transporting these components. Therefore, if it is put on the market, it will be sold as a finished product.

Further, the present inventor disclosed in Japanese Patent Application No. 2003-119864 (Patent Document 5) that when the hard fiber board is folded along a desired fold line, the side plate portion (1) to be folded is a side of the bottom plate portion (2). A central portion connected to each other via a fold line, and one or two protruding portions (3) connected to one or two side portions of the central portion via a fold line, and at least A protruding portion (4) or a fitting hole (7) for receiving the protruding portion (4) is provided in the side portion of the protruding portion (3) or in the vicinity of the side portion so as to face the other side plate portion, and the protruding portion ( 4) or an insertion hole (7) for receiving the protrusion in the vicinity of the side or the side of the other side plate (1 ′) or its protruding portion (3), facing the insertion hole (7). ) Or protrusions (4), and two side plate portions (1) A leakage prevention plate (8) held between the two, and the leakage prevention plate (8) is connected to all or part of the side of the bottom plate portion (2) via a folding line,
The opening is smaller than the bottom plate (2) or has the same size as the bottom plate (2) when assembled by fitting the projections of the plurality of side plate portions thus configured and the fitting holes. In addition to having water resistance and mechanical strength, a biodegradable monolithic polygonal planter pot that does not require adhesives or fasteners and can be easily assembled in the field is provided.

  However, in the case of this planter pot, it is difficult to fit the projection and the fitting hole, and the projection sucks water poured into the planter pot many times, swells and becomes soft, and acts as a fastener. There was a problem that no longer showed.

JP 2000-93001 A JP 2000-93008 A JP2001-48 JP 2001-78581 A Patent application 2003-119864

  The problem of the present invention is that it has water resistance and mechanical strength, does not require adhesives and fasteners, can minimize the conveyance space for conveyance from the manufacturer to the user, and is minimally stored. Biodegradable monolithic planter pot, which can be assembled in the field very easily, and the fasteners are mechanically strong even after many water injections, as well as this planter It is to provide a combination of a pot with a biodegradable seed mat and / or a biodegradable support for vine wrapping.

  As a result of intensive research, the inventor has found that when the hard fiber board is folded along a desired fold line, the side plate portion (1; 1 ') and the leakage prevention plate (5; 5') that are folded are the bottom plate portion. All or part of the sides of (2) are alternately connected via fold lines, and the side sides (1; 1 ′) are connected to one or two protruding portions (3 3 ′; 3 ″; 3 ″ ′), and hooking means or hooked means (4; 4 ′; 4) provided by cutting into the protruding portion (3; 3 ′; 3 ″; 3 ″ ′) ”; 4 ″ ′), and when the whole is folded along the fold line, the hooking means (4; 4 ″ ′) of the protruding portion (3; 3 ″ ′) is the other protruding portion (3 ″; 3 ′) of the hooked means (4 ″; 4 ′) or the side plate portion when the side plate portion and the leakage prevention plate are part of the side of the bottom plate portion (2). The leakage prevention plate (5; 5 ′) is provided so as to be hooked and overlapped with the hooking means, and the leakage prevention plate (5; 5 ′) has two protruding portions (3; 3 ′; 3 ″; 3 ″ ′) or the protruding portion and the side plate. This problem has been solved by a biodegradable monolithic polygonal planter pot characterized by being held and folded between the parts (1 '). Here, “monolithically assembled” means that a single hard fiber board can be simply folded and assembled.

  In a particularly advantageous embodiment of the invention, the biodegradable monolithic polygonal planter pot according to the invention is such that the hooking means (4; 4 "') are directed towards the central part of the side plate (1; 1'). And the hooked means (4 '; 4 ") is also shaped like a chevron or semi-circular toward the center of the side plate or is linear The hooking means (4; 4 ″ ′) and the hooked means (4 ′; 4 ″) are connected to each other. Since the hooking means and the hooking means having such a structure are relatively large, the connecting portion maintains high mechanical strength regardless of the number of water injections, and a very strong planter pot can be obtained. The hooking means and the hooked means may be slightly or complicatedly designed as long as they perform their original functions.

  The hard fiber board used in the present invention has durability and water resistance, and further has biodegradability that can be decomposed in about three months when buried in the soil. When it is used as a planter pot, the portion in contact with the outside air is dried, so it does not decompose and can be used over a long period of 6 to 8 months. Furthermore, if necessary, especially in the case of products that need to be used for a long period of time, an antifungal agent is applied or impregnated on the hard fiber board, especially the part in contact with the soil, or a waterproof resin is further applied to the soil contact part. You may perform a waterproofing process by apply | coating. However, since the period required for plant growth, flowering, and in some cases fruiting is about half a year, the use of antifungal agents and waterproofing are almost unnecessary. Examples of the hard fiber board used in the present invention include vulcanized fiber and Pasco (manufacturer: Hokuetsu Paper Co., Ltd.). The board has a thickness of 0.8 to 4 mm, preferably 1 to 3 mm, particularly preferably about 1 to 2.5 mm.

  The present invention also relates to a biodegradable planter pot combination characterized by combining the above-described biodegradable monolithic polygonal planter pot with a biodegradable seedling mat.

  This seedling mat is a plate-like material divided into dimensions suitable for inserting a biodegradable seedling mat into a planter pot by a cut line or a perforation line. The seedling mats may be arranged in a stacked state in the planter pot in a direction rising with respect to the bottom or in parallel with the bottom. Further, it is possible to arrange them in parallel near the bottom and arrange them in the direction of rising above them. In order not to inhibit the growth of plant roots, the planter pot is preferably arranged in a direction rising from the bottom.

  As a seedling mat, a biodegradable seedling mat that has been subjected to chemical treatment and made from a substantially non-fibrillated cellulosic fiber, in particular HK seedling mat (manufacturer: Hokuetsu Paper Co., Ltd.), Alternatively, other biodegradable substitutes, or woven fabrics and nonwoven fabrics made of cotton can be used.

  This seedling mat may be impregnated or mixed with a commercially available fertilizer. As the fertilizer, a fertilizer having immediate effect and a slow-acting fertilizer may be used alone or in combination depending on the purpose of use during the seedling raising period. Specific examples of fertilizers include nitrogenous fertilizers such as ammonium sulfate and ammonium chloride, potassium-based fertilizers such as potassium sulfate and potassium chloride, and phosphate-based fertilizers such as superphosphate lime and ammonium phosphate.

  The present invention further relates to the combination of a planter pot and a biodegradable support for vine wrapping used on vines such as morning glory. The support is composed of a columnar member made of hard fiber board and a member made of hard fiber board for connecting the columnar member in the lateral direction, and the columnar member has two cuts along the longitudinal direction at at least one end in the longitudinal direction. A plurality of L-shaped cross-section members, and the connecting members are a plurality of strip-shaped plate-like members having at least two cuts perpendicular to the longitudinal axis near at least both ends as means for connecting them in the lateral direction. Yes, each cut corresponds to the thickness of the mating member. The L-shaped cross section can be formed by folding along a fold line or a perforation line provided on one plate.

  Both the columnar member and the connecting member are made of the same material as the planter pot itself, for example, vulcanized fiber, Pasco (manufacturer: Hokuetsu Paper Co., Ltd.). The board has a thickness of 0.8 to 4 mm, preferably 1 to 3 mm, particularly preferably about 1 to 2.5 mm.

In a preferred embodiment of the present invention, the lower end of the columnar member may be placed inside the planter pot and fixed with soil and / or seedling mat filled in the planter pot, or in some cases, some mechanical fixing means, For example, it may be fixed by wire with a stapler, sewing with a thread, or the like. The fixed columnar member can be added to another columnar member so that the ridge portions of the columnar member are staggered with the cut portion as a joint. The connecting member joins the cut portion with the cut portion at the upper end of the columnar member, and thus connects the two columnar members. Similarly, cuts at both ends of another connecting member may be joined to a connecting member that connects another two columnar members and a notch provided with the connecting member at each intermediate point. In this way, the support tool can be fixed. This fixing can be strengthened according to the number of connecting members used.

  The planter pot, the columnar member and the connecting member of the present invention are flat plate-like objects before being folded and assembled, and before separating the seedling mat, it is one to several plate-like members. When the seedling mat member is transported together from the manufacturer to the user, the transport space can be minimized, and only a minimum space is required for storage. Therefore, it is also optimal for supplementary applications such as mail order and magazines.

  The structure of the planter pot may be larger, the same or smaller than the bottom, but when installing a support, it is advantageous that the bottom and the opening are the same or similar.

  The planter pot according to the present invention achieves a very high mechanical strength by using a hard fiber board and by using relatively large connecting means for connecting the side plate portions, that is, a hooking means and a hooked means. It is also possible to increase the amount of soil required for plant root growth.

  Furthermore, since it is very easy to assemble, the user can easily assemble in the field. From this, it is possible to participate from the formation of a plant growth environment to plant growth as educational materials for children, and there is also an advantage that it is effective for emotional education.

  It is possible to prevent tear propagation due to folding and to facilitate folding by making circular cuts with a diameter of about 2 to 5 mm at the ends and bent ends of the hooking means and hooked means of the planter pot of the present invention. Is advantageous.
