【発明の属する技術分野】
この発明は、公園緑地や道路の路肩、造成地の法面等に苗木を植え付ける緑化工事に使用する育苗ポットの技術分野に属し、更に云えば、苗木及び培土の充填を簡単、迅速、確実にできる育苗ポットに関する。
【０００２】
【従来の技術】
従来、緑化工事において、草木の種子や苗木を地面に植え付ける様々な育苗ポットが開発され、種々公知であり、実用に供されている。
【０００３】
例えば、特許文献１には、倒立円錐形状の筒体表面に螺旋状のネジ山と複数の孔を設けた育苗ポット（植生容器）が開示されている。また、この特許文献１の［使用状態を示す参考図］には、育苗ポットに充填した培土の上部を苗木の茎が通る程度の小孔を設けた蓋により塞いだ構造も開示されている。
【０００４】
特許文献２には、円筒体の胴部と円錐形状に尖った底部とを備え、前記胴部外周に螺旋状のねじれ凸部又は凹部と貫通穴とを設けた、苗木等の植え付けに用いられる育苗ポット（容器）が開示されている。
【０００５】
特許文献３は、本出願人の登録意匠であって、緑化工事の現場に敷設した防草シートの上から直接地面へ打ち込んで前記防草シートを固定する機能を兼ねた育苗ポットが開示されている。この育苗ポットは、下端部が尖った四角錐体形状の筒体から成り、上端外周部の四辺にそれぞれ独立したフランジを有すると共に、筒壁部にスリット状の通孔と、地中に該育苗ポットを打ち込んだ際に抜け止め機能を働く爪が設けられている。［使用状態を示す参考図］には、敷設された防草シートの上から育苗ポットを地面へ打ち込み、更にフランジの孔へ釘を打って固定する実施例が開示されている。
【０００６】
特許文献４も、本出願人の特許出願に係るものであり、緑化工事の現場の地面に敷設した防草シートの上から地面へ打ち込んで前記防草シートを固定する機能を兼ねた育苗ポットが開示されている。この育苗ポットは、円錐型又は角錐型若しくは柱状体を斜めに切断した形状から成り、側壁に通気等のための複数の孔が設けられている。

【本発明が解決しようとする課題】
上記した特許文献１〜４に開示された育苗ポットは、いずれも上端の開口から苗木及び培土を充填する構成において共通する。
しかし、育苗ポットの多くは開口部の直径がおよそ５ｃｍ、高さ１４ｃｍ程度に小さいものが一般的である。このように小さく狭い育苗ポット上端開口部から筒体内へ培土を充填し、且つ苗木を程良く中央部へ植え込む作業は甚だ面倒で作業性が悪い。一方、一つの緑化工事では、通常、苗木等を充填した育苗ポットを数百〜数千個のオーダーで使用するので、前記の如く苗木を植え込む作業の生産性の低さがこれら育苗ポットの実用化の大きな課題となっている。
【０００９】
とりわけ、特許文献１の［使用状態を示す参考図］に開示された育苗ポットの如く、筒体の上端開口部を蓋で塞ぐ構成の場合は、前記蓋によって雑草の発生を抑制する効果を認められるものの、同蓋の中央部に設けた小孔へ苗木の茎を通す細かい作業を必要とするため、その作業性及び生産性は極端に悪く、充填作業の熟練者でも音を上げるほど困難で効率の悪い作業となっている。元々、苗木は、その根部が団子状をなし、且つ茎部分は枝分かれして広がっており、小さな孔へ通すには適さない形態だからである。
【００１０】
次に、特許文献３及び４に開示された育苗ポットは、緑化工事において地面に敷設した防草シートの上から打ち込んで固定する機能、効果に特長を有する。しかし、筒体の打ち込みにより防草シートは部分的に破断され、筒体の外周面とシートの間に地面の露出部分が生じやすい。特許文献３に開示された育苗ポットは、筒体の上端外周部の四辺に設けたフランジによって地面の露出部分を覆い隠す効果もあるが、フランジが欠如した四隅部分は、実は防草シートが最も大きく破断されるところで、地面の露出が最も大きく生じやすい。この露出部分からは、雑草が発生し、苗木の生育が阻害される等々の問題が指摘されている。
【００１１】
本発明の目的は、育苗ポットを垂直方向に分割した２つの半割部材を組み合わせて成る構成とし、培土及び苗木の充填を熟練を要さずに誰でも簡単、迅速、且つ能率良く行うことができる育苗ポットを提供することである。
【００１２】
本発明の次の目的は、育苗ポットの上端外周縁に沿ってその全周にほぼ等しい幅で延びるフランジを有し、防草シートの上から地面に育苗ポットを埋込んで前記防草シートを固定した際に、育苗ポットの外周に地面の露出部分を生じさせない育苗ポットを提供することである。
【００１３】
本発明の更なる目的は、道路の縁石の傍らの狭い場所、石垣等における石と石の隙間、又はその窪地等へ苗木を植え付けることが容易な育苗ポットを提供することにある。
【００１４】

【００２４】
【発明の実施形態及び実施例】
以下、図面に基づいて、請求項１〜１０に記載した発明に係る育苗ポットの実施形態について、それぞれ説明する。
【００２５】
（第１の実施形態）
先ず、請求項１に記載した発明に係る育苗ポットの実施形態を図１〜図７に基づいて説明する。
【００２６】
この育苗ポット１は、図１と図２に使用状態を示したように、下端部が尖った円錐型形状の筒体を垂直方向に二分したに等しい同形、同大の２個の半割部材１ａ，１ａの組み合わせで構成され、筒体内に苗木２及び培土４を充填して地面へ埋込み、前記苗木２の植え付けを行うものである。前記半割部材１ａ，１ａの組み合わせ状態を保持する結合手段としてのリング部材３０を含む。図示した半割部材１ａは、最も好ましい実施例として二等分に分割した形態を示すがこの限りではない。非等分に二分した形態の組み合わせで実施することもできる。
【００２７】
この育苗ポット１の形状は、その下部が地面へ埋込む（又は打ち込む）のに適した尖り形状であれば良く、図１に示したような円錐体形状に限らない。例えば四角錐体等の多角錐型形状や、柱状体を斜めに切断したような形状でもよい。育苗ポット１の材質はプラスチック製樹脂、好ましくは生分解性プラスチック又は崩壊性プラスチックを用いると環境に優しくて好都合である。とりわけ、材質に生分解性プラスチック又は崩壊性プラスチックを用いると、地面に埋込まれた育苗ポット１は半年〜数年で分解されるので、植え付けた苗木２が成長と共に根を張り、茎（幹）が太くなっても、その成長を当該育苗ポット１が妨害し又は阻害するおそれは一切無い。もっとも、発泡した又は発泡しない通常の樹脂、或いはセメント、粘土、紙や樹皮等の動植物由来の腐食性材料等で同様に育苗ポット１を製作して実施することもできる。
【００２８】
図３Ａ，Ｂは、前記半割部材１ａの正面図及び平面図を示している。この半割部材１ａの大きさは、高さＨが約１５０ｍｍ程度である。もちろん、寸法は植え付ける苗木２や種の大きさ等に従って適宜設計される。
【００２９】
半割部材１ａには、上端の開口部を閉じる半割形状の蓋部分１２が、上端部よりも少し下がった位置、例えば約３ｍｍ程度低い位置に略水平に一体成形されている。蓋部分１２を半割部材１ａの上端部よりも少し低く設けた理由は、育苗ポット１の上端部に窪みを設け、この窪みに雨水を溜めて苗木２の根本の培土４へ水分を供給するためである。もちろん、前記蓋部分１２は、筒体上端に付設して前記窪みを設けない構成でも実施できる。
【００３０】
上記した蓋部分１２のほぼ中央部には、育苗ポット１に植え付ける苗木２の茎を導き出すための孔部３が切り欠き形状（半円形）に設けられている。この孔部３の大きさ（寸法又は直径Ｌ）は、植え付ける苗木２の茎の太さを許容して、できるだけ茎と孔部３との間に隙間を生じさせない寸法にする。培土４の露出部分、即ち雑草の発生面積を少なくし、苗木２の生育不良を防止し、且つ雑草の除草作業を軽減するためである。
【００３１】
次に、前記半割部材１ａの上端の外周縁には、少なくとも一定以上の幅のフランジ１０が、外周縁に沿って全長に（半周に連続して）略水平に設けられている。従って、２個の半割部材１ａ，１ａを図１のように組み合わせると、フランジ１０，１０は完全な円形状となる。よって、緑化工事の現場において、地面に敷設した防草シート等のシート材の上から育苗ポット１を地面へ埋込んだ際に、仮にシート材に破断が生じても、前記フランジ１０によって当該シート材が押さえられ、地面の露出が防止されて雑草の発生が抑制される。フランジ１０を少なくとも一定以上の幅に設ける意味は、前記地面の露出を防ぐ効果を達成するためであり、前記効果を奏する幅以上であれば、フランジ１０の幅寸の大小変化を問うものではない。
【００３２】
フランジ１０，１０の平面形状は、例えば筒体が四角錐体、多角錐体形状であれば、夫々四角形、多角形状に連続する形状が好適である。フランジ１０に釘打ち用の孔を設けても良い。
【００３３】
半割部材１ａの筒壁部には、充填した培土４が漏れない形状、大きさの複数の通孔１１が形成されている。この通孔１１は、育苗ポット１内の培土４における空気の通気、水分の排水を保ち、苗木２の成長に伴う根の延び出しを許容するために育苗ポット１の筒壁部に満遍なく多数設けられている。従って、この通孔１１の形状、大きさは、図１等に示したスリット形状の孔に限定されない。例えば円形又は楕円形状の孔でも好適に実施される。
【００３４】
半割部材１ａの筒壁部には、更に育苗ポット１を地中へ埋込んだ際に抜け止め機能を働く形状、例えば楔形状の抜止め突起１６が複数外方へ突き出されている（請求項８記載の発明）。
【００３５】
前記抜止め突起１６の一部は、前記半割部材１ａの分割面に該分割面と平行方向に複数設けられている。この分割面に設けられた抜止め突起１６は、当該分割面と平行方向に幅広く形成され、２個の半割部材１ａ，１ａを組み合わせる際に当接面を兼ねるものとされ、分割面の上下方向に３個ずつ、各々左右対称な配置で設けられている（請求項９記載の発明）。
【００３６】
分割面に設けた前記抜止め突起１６のうち、下方側の２個ずつの当接面には、図３に示すように、２個の半割部材１ａ，１ａの組み合わせ状態を保持する結合手段としての掛止め部１８が付設されている（請求項７，１０記載の発明）。
【００３７】
図４と図５は、前記抜止め突起１６に付設した掛止め部１８の構造を概略的に示している。
図４において左側の抜止め突起１６の当接面には、前記掛止め部１８を構成する鈎形状の雄型留め突起１８ａと雌型留め孔１８ｄの対が設けられている。右側の抜止め突起１６の当接面には、前記雌型留め孔１８ｄへ嵌り込む鈎形状の雄型留め突起１８ｃと、前記雄型留め突起１８ａを受け入れる雌型留め孔１８ｂの対が設けられている。
【００３８】
従って、これら雄型留め突起１８ａ，１８ｃと雌型留め孔１８ｂ，１８ｄの対は、図５に示したように、２個の半割部材１ａ，１ａが向かい合わせに組み合わされた際に、相向かいとなるもの同士が嵌り合って、当該２個の半割部材１ａ，１ａの結合状態をしっかり保持する。
【００３９】
上記した掛止め部１８による接合のみで組み合わされた育苗ポット１は、通例はほぼ同形、同大の孔を地面（及びシート）に掘って埋込むが、柔らかい地面の場合はハンマー等で直接地面へ打ち込むこともある。その際の衝撃で前記掛止め部１８が外れて分解することの無いように、２個の半割部材１ａ，１ａの組み合わせ状態を保持する更なる手段として、図２に示したように、育苗ポット１の外周部を締め付けるリング部材３０が好適に使用される（請求項６記載の発明）。
【００４０】
リング部材３０は、上記したように２個の半割部材を保持する手段であり、その形態は図１に示した筒形状からなるリング状の形態のみならず、ゴムバンドやプラスチックバンドの如き締め付け力を発揮する形態でも好適に実施される。リング部材３０の材質は、育苗ポット１と同様、生分解性又は崩壊性プラスチック等のプラスチック製樹脂、セメント、粘土、動植物由来の腐食性材料の他に、ゴム等の弾性樹脂も好適に使用される。因みに、図１では、前記リング部材３０の取り付け場所をフランジ１０の直下の平行部位としているが、これに限定されない。リング部材３０の取り付け場所は、育苗ポット１の筒体の上下何れの場所でも良い。
【００４１】
図６は、半割部材１ａの尖端部を結合する手段として、尖頭部に設けた、だぼ２０とだぼ孔２１の結合構造を示している。だぼ２０とだぼ孔２１は、２個の半割部材１ａ，１ａを組み合わせた際に相互に嵌り合い、尖頭部の位置ズレを防止する効果がある。
【００４２】
次に図７は、上記構成の育苗ポット１を使用した緑化工事の一実施例を示している。
育苗ポット１は、図２に示したように、培土４を密実に充填した２つの半割部材１ａ，１ａの一方に、苗木２を、その茎が孔部３を通るように植え付ける。そして、２つの半割部材１ａ，１ａを相向かいに組み合わせ、掛止め部１８により結合させ、更にリング部材３０を嵌めて拘束させ図１のように完成する。斯くして用意された育苗ポット１は、緑化工事の現場に必要数搬入される。そして、予め地面に防草シート等のシート材３３を敷く等して、そのシート材３３の上から孔あけ機を用いて地面に育苗ポット１とほぼ同形、同大の孔を掘り、その孔の中へ埋込む。育苗ポット１は、例えば３０ｃｍ間隔位で地面へ複数埋込み、苗木２を植える目的と同時に前記シート材３３を地面に固定する目的の双方を達成する。地面が柔らかい場合には、シート材３３の上から育苗ポット１をハンマー等を用いて直接地面へ打ち込むことも行う。
【００４３】
（第２の実施形態）
次に図８Ａ，Ｂは、蓋部分１２’及びフランジ１０’の接合端に重ね代部１７，１９を有した半割部材１ａ’，１ａ’から成る育苗ポット１’の実施形態を示している。
【００４４】
この育苗ポット１’は、上記第１の実施形態と大部分共通する構成であるが、半割部材１ａ’の蓋部分１２’及びフランジ１０’における夫々２つの接合端のうちの一方に重ね代部１７，１９を設けた構成を特徴とする。即ち、育苗ポット１’は、半割部材１ａ’の蓋部分１２’及びフランジ１０’の接合端における形状を除けば、全て上記第１の実施形態の育苗ポット１と構造、材質等において同じである。
【００４５】
前記蓋部分１２’には、図８Ａ，Ｂに示したように、その中央部の切り欠き形状の孔部３’の両側の接合端のうちの一方の接合端を少し延長した重ね代部１７が形成されている。この重ね代部１７は、その厚みにテーパー処理が施されており、半割部材１ａ’、１ａ’の組み合わせ状態において前記重ね代部１７が向かい合う蓋部分１２’の接合端の上面に乗り上げて（又は下面に潜り込んで）重なる接合構造を採る。蓋部分１２’の重ね代部１７の形状は、図示した形状に限らず、半割部材１ａ’，１ａ’の接合状態において蓋部分１２’，１２’の接合部分の合わせ目が透かない接合構造をとり得る形状であれば良い（以上、請求項４記載の発明）。
【００４６】
前記フランジ１０’は、図８Ａ，Ｂに示したように、当該フランジ１０’の両端の接合端のうち、一方の接合端が少し延長され、その延長部分をフランジ１０’の厚み相当分だけ印籠型に隆起した重ね代部１９が形成されている。この重ね代部１９は、半割部材１’ａ、１’ａの組み合わせ状態において前記重ね代部１９が向かい合う相手側のフランジ１０’との隙間を覆い隠すように重なり合う印籠型の接合構造をとる。フランジ１０’における重ね代部１９の形状は、図示した形状に限らず、蓋部分１２’と同様にフランジ１０’，１０’の接合部分の合わせ目が透かない接合構造をとりうる形状であれば良い（以上、請求項５記載の発明）。
【００４７】
前記蓋部分１２’及びフランジ１０’の重ね代部１７，１９の機能は、上記した第１の実施形態の育苗ポット１において、２個の半割部材１ａ，１ａを組み合わせた場合にその組み立て精度等の問題から生じる蓋部分１２，１２、又はフランジ１０，１０の各接合部分の隙間を塞ぐことにある。従って、本実施形態の育苗ポット１’は、より確実に前記接合部分の隙間を塞いで極僅かな培土４又は地面の露出部分をなくし、雑草の発生を抑えることができるのである。
【００４８】
（第３の実施形態）
次に図９は、請求項２に記載した発明に係る育苗ポット７の実施形態を示している。
【００４９】
この育苗ポット７も、上記第１の実施形態と大部分共通する構成であるが、半割部材７ａのフランジを全部除去した構成が異なる。即ち、育苗ポット７は、図１と照らし合わせてみると明らかなように、半割部材７ａにフランジを設けていない点を除けば、基本的に上記第１の実施形態に示した育苗ポット１と構造、材質等においてほぼ同様である。半割部材７ａの上端外周縁には、２個の半割部材７ａ，７ａを組み合わせた育苗ポット７の外周部を締め付けるリング部材３０が突き当たる鍔部１５が外側に向かって設けられている。
【００５０】
本実施形態の育苗ポット７は、フランジを省略して実質的に細身の形状に構成したので、育苗ポットを埋め込む際にフランジが邪魔となる場所、例えば道路の縁石の傍らとか、石垣における石と石との隙間又は窪地、法面に積み上げた土嚢と土嚢との隙間等の狭隘部へフランジを気にすることなく容易に埋込むことができる。
【００５１】
（第４の実施形態）
次に図１０及び図１１は、請求項３に記載した発明に係る育苗ポット７’の実施形態を示している。
【００５２】
この育苗ポット７’は、実質的に上記第３の実施形態において説明した２個の半割部材７ａ，７ａを共通に使用するもので、その組み合わせ状態を保持するリング部材３１との組み合わせを特徴とする。とりわけ、前記リング部材３１は、その上端外周縁の全長（全周）に完全円形状に連続した一定幅のフランジ４０を一体に備えた構成を特徴とする。リング部材３１の本来の機能は、組み合わせた２個の半割部材７ａ，７ａの形態を保持することであり、フランジ４０を一体に成形されたゴムバンド又はプラスチックバンドの如き締め付け力を発揮する材であれば十分であり、図１１に示した形態に限定されない。
【００５３】
この育苗ポット７’は、上記第３の実施形態の育苗ポット７の用途が狭い場所に限定されることに鑑み、フランジ４０を備えたリング部材３１と組み合わせることで、第１の実施形態の育苗ポット１と同様な用途にも使用できるよう汎用性を付与したことを特徴とする。従って、上記した第１の実施形態の育苗ポット１と同様に地面の露出を防止しつつもシート材３３の固定を行い、前記苗木２の植え付けができる。即ち、リング部材３１のフランジ４０は、上記第１の実施形態の育苗ポット１におけるフランジ１０，１０と同様の目的と作用を働く。
【００５４】
本実施形態の場合、フランジ４０は、当初からリング部材３１の外周縁、即ち育苗ポット７’の外周縁を一周する完全円形状に一体成形されている。よって、上記第１の実施形態の円形状のフランジ１０，１０が半割部材１ａの組み合わせ状態において接合部に隙間を生じやすく、雑草が芽を出す可能性があることと対照的である。即ち、当該育苗ポット７’のフランジ４０は、地面に敷設したシート材３３の上から育苗ポット７’を地面へ打ち込んだ際に、より確実に地面の露出部分を覆うことができる。
【００５５】
【本発明が奏する効果】
請求項１〜１０に記載した発明に係る育苗ポットは、垂直方向に分割した２個の半割部材に培土を夫々充填し、更に一方の半割部材に茎が孔部を通るように苗木を付設し、その上で２個の半割部材を相向かいに組み合わせて完成する構成としたので、熟練を要さなくとも、手間がかからず、簡便、迅速、確実に能率良く大量の苗付き育苗ポットを作成できる。
【００５６】
更に、請求項１又は３記載の育苗ポットは、その上端外周縁に沿って隙間なく放射状に延びるフランジを設けたので、防草シートの上から地面に育苗ポットを埋込んで前記防草シートを固定した際に、育苗ポットの外周に生じやすい地面の露出を確実に防ぐことができる。従って、防草シートと育苗ポットとの間に露出した地面から雑草が発生する不都合を可及的に防止でき、除草作業の煩わしさからも大幅に解放される。
【００５７】
また、請求項２記載の育苗ポットは、道路の縁石の傍らとか、石垣の石と石の隙間、又は積み上げた土嚢の隙間等の狭隘部への苗木の植え付けに適する。

[Problems to be solved by the present invention]
The seedling pots disclosed in Patent Literatures 1 to 4 described above have a common configuration in which seedlings and soil are filled from the opening at the upper end.
However, most of the seedling raising pots generally have an opening having a diameter of about 5 cm and a height as small as about 14 cm. The operation of filling the cultivation soil into the cylinder through the small opening of the small seedling raising pot and opening the seedlings in the central portion is extremely troublesome and poor in workability. On the other hand, in one greening work, usually, nursery pots filled with seedlings and the like are used in the order of several hundred to several thousand, so that the low productivity of planting seedlings as described above makes these nursery pots practically usable. Has become a major challenge for
[0009]
In particular, in the case of a configuration in which the opening at the upper end of the cylindrical body is closed with a lid, as in the seedling pot disclosed in [Reference diagram showing the state of use] of Patent Document 1, the effect of suppressing the generation of weeds by the lid is recognized. However, since it requires a fine work of passing the stalks of the seedlings into the small hole provided in the center of the lid, the workability and productivity are extremely poor, and even a skilled filling worker is difficult enough to raise the sound. It is inefficient work. Originally, a seedling has a root-shaped dumpling shape and a stem portion that is branched and spread, which is not suitable for passing through a small hole.
[0010]
Next, the seedling pots disclosed in Patent Literatures 3 and 4 have a feature of a function and an effect of driving and fixing a grass-proof sheet laid on the ground in greening work. However, the grass sheet is partially broken by the driving of the cylindrical body, and an exposed portion of the ground is likely to be formed between the outer peripheral surface of the cylindrical body and the sheet. The seedling pot disclosed in Patent Document 3 also has an effect of covering the exposed portion of the ground with flanges provided on the four sides of the outer periphery of the upper end of the cylindrical body. Where a large break occurs, the ground is most likely to be exposed. Problems such as the occurrence of weeds and the inhibition of the growth of seedlings are pointed out from the exposed portions.
[0011]
An object of the present invention is to combine two half-split members obtained by dividing a seedling raising pot in the vertical direction, so that anyone can easily, quickly, and efficiently perform cultivation and filling of seedlings without skill. It is to provide a seedling pot that can be used.
[0012]
The next object of the present invention is to have a flange extending along the upper peripheral edge of the seedling raising pot at a width substantially equal to the entire circumference thereof, and burying the seedling raising pot in the ground from above the weed control sheet to remove the weed control sheet. An object of the present invention is to provide a seedling raising pot that does not cause an exposed portion of the ground on the outer periphery of the seedling raising pot when fixed.
[0013]
A further object of the present invention is to provide a seedling pot that can easily plant seedlings in a narrow place beside a curb of a road, a gap between stones in a stone wall, or a depression thereof.

Embodiments and Examples of the Invention
Hereinafter, embodiments of the seedling raising pot according to the invention described in claims 1 to 10 will be described with reference to the drawings.
[0025]
(1st Embodiment)
First, an embodiment of a seedling raising pot according to the first aspect of the present invention will be described with reference to FIGS.
[0026]
As shown in FIGS. 1 and 2, the seedling raising pot 1 has two half-shaped members of the same shape and the same size, which are equivalent to vertically dividing a conical cylindrical body having a sharp lower end into two. The seedlings 2 and the soil 4 are filled in a cylinder and embedded in the ground to plant the seedlings 2. A ring member 30 is provided as coupling means for maintaining the combined state of the half members 1a. The illustrated half member 1a is shown as a most preferred embodiment, but is not limited thereto. It is also possible to carry out a combination of unequally divided forms.
[0027]
The shape of the seedling raising pot 1 is not limited to the cone shape as shown in FIG. 1 as long as its lower portion is suitable for embedding (or driving) into the ground. For example, a polygonal pyramid shape such as a quadrangular pyramid or a shape obtained by diagonally cutting a columnar body may be used. The use of plastic resin, preferably biodegradable plastic or degradable plastic, as the material of the seedling raising pot 1 is environmentally friendly and convenient. In particular, when a biodegradable plastic or a disintegrable plastic is used as the material, the seedling pot 1 embedded in the ground is decomposed in six months to several years, so that the planted seedlings 2 take root with growth and grow in stems (stems). ) Becomes thicker, there is no risk of the seedling pot 1 hindering or inhibiting its growth. Of course, the seedling raising pot 1 can be similarly manufactured and made of a foamed or non-foamed ordinary resin, or a corrosive material derived from animals and plants such as cement, clay, paper and bark.
[0028]
3A and 3B show a front view and a plan view of the half member 1a. As for the size of the half member 1a, the height H is about 150 mm. Of course, the dimensions are appropriately designed according to the size of the seedling 2 to be planted and the seed.
[0029]
A half-shaped lid portion 12 for closing the opening at the upper end of the half member 1a is integrally formed substantially horizontally at a position slightly lower than the upper end, for example, at a position lower by about 3 mm. The reason why the lid portion 12 is provided slightly lower than the upper end portion of the half member 1a is that a dent is provided in the upper end portion of the seedling raising pot 1 and rainwater is collected in the dent to supply moisture to the root soil 4 of the seedling 2. That's why. Needless to say, the lid portion 12 can be implemented with a configuration provided at the upper end of the cylindrical body and not having the depression.
[0030]
At a substantially central portion of the above-mentioned lid portion 12, a hole portion 3 for leading out a stem of a seedling 2 to be planted in the seedling raising pot 1 is provided in a cutout shape (semicircular shape). The size (dimension or diameter L) of the hole 3 is set so as to minimize the gap between the stem and the hole 3 while allowing the thickness of the stem of the seedling 2 to be planted. This is because the exposed portion of the cultivation soil 4, that is, the area where weeds are generated is reduced, the growth of the seedlings 2 is prevented from growing poorly, and the weed weeding operation is reduced.
[0031]
Next, a flange 10 having at least a certain width or more is provided substantially horizontally along the outer peripheral edge of the upper half of the half member 1a over the entire length thereof (continuously along the half circumference). Therefore, when the two half members 1a, 1a are combined as shown in FIG. 1, the flanges 10, 10 have a perfect circular shape. Therefore, at the site of the greening work, when the seedling raising pot 1 is buried in the ground from above a sheet material such as a grass-proof sheet laid on the ground, even if the sheet material is broken, the sheet can be broken by the flange 10. The timber is held down, the exposure of the ground is prevented, and the occurrence of weeds is suppressed. The meaning of providing the flange 10 at least in a certain width or more is to achieve the effect of preventing the ground from being exposed, and it does not matter how large or small the width of the flange 10 is as long as it is equal to or more than the width at which the effect is exerted. .
[0032]
For example, if the cylindrical body is a quadrangular pyramid or a polygonal pyramid, the planar shape of the flanges 10 and 10 is preferably a shape continuous with a quadrangle and a polygon, respectively. A hole for nailing may be provided in the flange 10.
[0033]
A plurality of through-holes 11 are formed in the cylindrical wall portion of the half member 1a in a shape and a size in which the filled soil 4 does not leak. A large number of the through holes 11 are provided evenly in the cylindrical wall portion of the seedling raising pot 1 in order to maintain the ventilation of air and drainage of water in the cultivation soil 4 in the seedling raising pot 1 and to allow the roots to extend with the growth of the seedling 2. Have been. Therefore, the shape and size of the through hole 11 are not limited to the slit-shaped holes shown in FIG. For example, a circular or elliptical hole is also suitably implemented.
[0034]
A plurality of retaining protrusions 16, for example, in the form of wedges, which protrude outward from the cylindrical wall portion of the half-split member 1 a, function as a retaining function when the seedling raising pot 1 is embedded in the ground (claim). Item 8)).
[0035]
A plurality of the retaining projections 16 are provided on the dividing surface of the half-member 1a in a direction parallel to the dividing surface. The retaining projections 16 provided on the divided surface are formed to be wide in the direction parallel to the divided surface, serve as a contact surface when the two half members 1a, 1a are combined, and serve as upper and lower surfaces of the divided surface. Three pieces are provided in each direction in a symmetrical arrangement (the invention according to claim 9).
[0036]
As shown in FIG. 3, connecting means for holding the combined state of the two half members 1a, 1a on the two contact surfaces on the lower side of the retaining projections 16 provided on the divided surface. A hook portion 18 is additionally provided (the invention according to claims 7 and 10).
[0037]
FIG. 4 and FIG. 5 schematically show the structure of a latching portion 18 attached to the retaining projection 16.
In FIG. 4, a pair of a hook-shaped male retaining projection 18 a and a female retaining hole 18 d constituting the latching portion 18 is provided on the contact surface of the left retaining projection 16. The contact surface of the right retaining projection 16 is provided with a pair of a hook-shaped male retaining projection 18c that fits into the female retaining hole 18d and a female retaining hole 18b that receives the male retaining projection 18a. ing.
[0038]
Therefore, as shown in FIG. 5, the pair of the male retaining projections 18a, 18c and the female retaining holes 18b, 18d forms a pair when the two half members 1a, 1a are combined face to face. Opposite members are fitted to each other to firmly hold the two half members 1a, 1a in a connected state.
[0039]
The seedling pot 1 combined only by the above-described hooking portion 18 is usually dug and buried in the ground (and sheet) with a hole of substantially the same shape and the same size. Sometimes it is driven. As a further means for maintaining the combined state of the two half-members 1a, 1a, as shown in FIG. The ring member 30 for tightening the outer peripheral portion of the pot 1 is preferably used (the invention according to claim 6).
[0040]
The ring member 30 is a means for holding the two half members as described above. The form is not limited to the cylindrical ring shape shown in FIG. It is suitably implemented even in a form that exerts force. Similar to the seedling pot 1, the material of the ring member 30 is preferably plastic resin such as biodegradable or degradable plastic, cement, clay, corrosive material derived from animals and plants, and elastic resin such as rubber. You. Incidentally, in FIG. 1, the place where the ring member 30 is attached is a parallel portion immediately below the flange 10, but the present invention is not limited to this. The ring member 30 may be attached at any position above or below the tubular body of the seedling raising pot 1.
[0041]
FIG. 6 shows a connecting structure of the dowel 20 and the dowel hole 21 provided at the pointed head as means for connecting the pointed end of the half member 1a. The dowel 20 and the dowel hole 21 are fitted to each other when the two half members 1a, 1a are combined, and have an effect of preventing a displacement of the pointed head.
[0042]
Next, FIG. 7 shows an embodiment of a greening work using the seedling raising pot 1 having the above configuration.
As shown in FIG. 2, the seedling raising pot 1 has a seedling 2 planted in one of the two half members 1 a, 1 a densely filled with the cultivation soil 4 so that the stem thereof passes through the hole 3. Then, the two half members 1a, 1a are combined to face each other, connected by the hooking portion 18, and furthermore, the ring member 30 is fitted and restrained to complete as shown in FIG. The seedling pots 1 thus prepared are carried in a required number to the site of the greening work. Then, a sheet material 33 such as a grass sheet is laid on the ground in advance, and a hole having substantially the same shape and the same size as the seedling pot 1 is dug on the ground using a punching machine from above the sheet material 33. Embed in The seedling raising pots 1 are embedded in the ground at intervals of, for example, about 30 cm to achieve both the purpose of planting the seedlings 2 and the purpose of fixing the sheet material 33 to the ground. When the ground is soft, the seedling raising pot 1 is directly driven into the ground from above the sheet material 33 using a hammer or the like.
[0043]
(Second embodiment)
Next, FIGS. 8A and 8B show an embodiment of the seedling raising pot 1 ′ composed of the half members 1 a ′ and 1 a ′ having overlap portions 17 and 19 at the joining ends of the lid portion 12 ′ and the flange 10 ′. .
[0044]
The seedling raising pot 1 'has a configuration substantially common to that of the first embodiment, but overlaps with one of two joining ends of the lid portion 12' and the flange 10 'of the half member 1a'. It is characterized by a configuration in which the parts 17 and 19 are provided. That is, the seedling raising pot 1 'is all the same in structure, material, and the like as the seedling raising pot 1 of the first embodiment, except for the shape at the joining end of the lid portion 12' and the flange 10 'of the half member 1a'. is there.
[0045]
As shown in FIGS. 8A and 8B, the lid portion 12 'has an overlapping margin portion 17 in which one of the joining ends on both sides of the cutout hole 3' at the center is slightly extended. Is formed. The overlap margin 17 is tapered to its thickness, and rides on the upper surface of the joint end of the lid portion 12 'facing the overlap margin 17 in the combined state of the half members 1a', 1a '( Alternatively, a bonding structure that overlaps (under the bottom surface) is employed. The shape of the overlapping margin portion 17 of the lid portion 12 'is not limited to the shape shown in the drawing, and a joint structure in which the joint of the junction portions of the lid portions 12', 12 'is not transparent in the joined state of the half members 1a', 1a '. The shape may be any shape (above, the invention according to claim 4).
[0046]
As shown in FIGS. 8A and 8B, one end of the flange 10 ′ is slightly extended from one end of the flange 10 ′. An overlap portion 19 protruding from the mold is formed. The overlapping portion 19 has an intaglio type joining structure in which the overlapping portions 19 overlap each other so as to cover the gap between the overlapping portion 19 and the opposing flange 10 'in the combined state of the half members 1'a and 1'a. . The shape of the overlap portion 19 in the flange 10 ′ is not limited to the shape shown in the drawing, and may be any shape as long as it can have a joint structure in which the joints of the joint portions of the flanges 10 ′ and 10 ′ are not transparent like the lid portion 12 ′. Good (above, the invention according to claim 5).
[0047]
The function of the overlapping portions 17, 19 of the lid portion 12 'and the flange 10' is such that the assembling accuracy of the seedling raising pot 1 of the first embodiment described above when two half members 1a, 1a are combined. In other words, the problem is to close the gaps between the lid portions 12 and 12 or the joining portions of the flanges 10 and 10 caused by such problems. Therefore, the seedling raising pot 1 'of the present embodiment can more reliably close the gap between the joining portions, eliminate the very small cultivated soil 4 or the exposed portion of the ground, and suppress the occurrence of weeds.
[0048]
(Third embodiment)
Next, FIG. 9 shows an embodiment of the seedling raising pot 7 according to the second aspect of the present invention.
[0049]
The seedling raising pot 7 also has a configuration that is substantially the same as the first embodiment, but differs in a configuration in which the flange of the half member 7a is entirely removed. That is, as apparent from the comparison with FIG. 1, the seedling raising pot 7 is basically similar to the seedling raising pot 1 shown in the first embodiment except that the half member 7a is not provided with a flange. This is almost the same in structure, material and the like. A flange 15 against which a ring member 30 for tightening an outer peripheral portion of the seedling raising pot 7 in which the two half members 7a are combined is provided on an outer peripheral edge of an upper end of the half member 7a.
[0050]
Since the seedling raising pot 7 of the present embodiment is formed in a substantially slender shape by omitting the flange, when the seedling raising pot is embedded, a place where the flange interferes, for example, beside a curb of a road or a stone in a stone wall. The flange can be easily embedded in a narrow part such as a gap or a depression between the stones and a gap between the sandbags stacked on the slope, without worrying about the flange.
[0051]
(Fourth embodiment)
Next, FIGS. 10 and 11 show an embodiment of a seedling raising pot 7 ′ according to the third aspect of the present invention.
[0052]
The seedling raising pot 7 'uses the two half members 7a, 7a substantially described in the third embodiment substantially in common, and is characterized by a combination with a ring member 31 holding the combined state. And In particular, the ring member 31 is characterized in that a flange 40 of a constant width that is continuous in a perfect circular shape is integrally provided over the entire length (entire circumference) of the outer peripheral edge of the upper end. The original function of the ring member 31 is to maintain the configuration of the two half members 7a, 7a combined, and a material that exerts a tightening force such as a rubber band or a plastic band formed integrally with the flange 40. Is sufficient, and the present invention is not limited to the embodiment shown in FIG.
[0053]
This seedling raising pot 7 'is combined with the ring member 31 provided with the flange 40 in view of the fact that the use of the seedling raising pot 7 of the third embodiment is limited to a narrow place. It is characterized by providing versatility so that it can be used for the same applications as the pot 1. Accordingly, similarly to the seedling raising pot 1 of the first embodiment, the sheet material 33 is fixed and the seedlings 2 can be planted while preventing the ground from being exposed. That is, the flange 40 of the ring member 31 has the same purpose and functions as the flanges 10 and 10 in the seedling raising pot 1 of the first embodiment.
[0054]
In the case of the present embodiment, the flange 40 is integrally formed from the beginning into a complete circular shape that goes around the outer peripheral edge of the ring member 31, ie, the outer peripheral edge of the seedling raising pot 7 '. This is in contrast to the fact that the circular flanges 10 of the first embodiment tend to form gaps at the joints in the combined state of the half members 1a, and that weeds may sprout. That is, the flange 40 of the seedling raising pot 7 'can more reliably cover the exposed portion of the ground when the seedling raising pot 7' is driven into the ground from above the sheet material 33 laid on the ground.
[0055]
[Effects of the present invention]
The seedling raising pot according to the invention as set forth in claims 1 to 10, fills the cultivated soil into two vertically divided half members, and further transfers the seedling to one of the half members so that the stem passes through the hole. Attached and then two half-split members are combined to face each other, so that it can be completed easily, quickly, reliably and efficiently without the need for skill. A nursery pot can be created.
[0056]
Furthermore, since the seedling growing pot according to claim 1 or 3 is provided with a flange extending radially without a gap along the outer peripheral edge of the upper end thereof, the seedling growing pot is buried in the ground from above the weeding sheet. When fixed, it is possible to reliably prevent the ground from being exposed on the outer periphery of the seedling raising pot. Therefore, the inconvenience of weed generation from the ground exposed between the weed prevention sheet and the seedling raising pot can be prevented as much as possible, and the troublesome weeding work is greatly relieved.
[0057]
In addition, the seedling raising pot according to claim 2 is suitable for planting seedlings in a narrow portion such as beside a curb of a road, a gap between stones of a stone wall, or a gap between piled sandbags.
