Abstract
【解決手段】本発明に係る中空容器における内蔵部品の結合方法は、本金型に転写されたパリソンに対し、結合対象の第1内蔵部品2および第2内蔵部品3を取り付け、本金型を閉じて第1内蔵部品2と第2内蔵部品3とを未結合状態として中空容器1を成形する中空容器成形工程と、本金型から取り出した中空容器1の冷却時に、中空容器1の外面を押圧部23により押圧して中空容器1の変位により第1内蔵部品2と第2内蔵部品3とを結合状態にする内蔵部品結合工程と、を有する。
【選択図】図2
Description
図1に示す中空容器成形工程は、大略、本金型11に転写されたパリソンPに対し、結合対象の内蔵部品(第1内蔵部品2、第2内蔵部品3)を取り付け、本金型11を閉じて第1内蔵部品2、第2内蔵部品3を未結合状態として中空容器1を成形する工程である。
図2に示す内蔵部品結合工程は、大略、本金型11(図1)から取り出した中空容器1の冷却時に、中空容器1の外面を押圧して中空容器1の変位により第1内蔵部品2と第2内蔵部品3とを結合状態にする工程である。なお、図2では中空容器1のピンチオフ部は省略している。
次に、中空容器1を自動車の燃料タンクTとした場合の第1内蔵部品2、第2内蔵部品3の複数の実施例について説明する。
図3、図4に示す第1内蔵部品2、第2内蔵部品3は、結合することにより燃料タンクTの下面部Taと上面部Tbとにわたって鉛直状に立設される第1支柱4、第2支柱5からなり、これらは燃料タンクTの圧縮変形を阻止する機能を担う。第1支柱4、第2支柱5は例えば円柱形状を呈した部材であり、中空の部材としてもよいし、中実の部材としてもよい。
図5(a)と図6(a)、(b)は第2実施例の説明図であり、図5(a)は内蔵部品の結合状態を示す全体側面図、図6(a)、(b)はそれぞれ内蔵部品の未結合状態、結合状態を示す部分側面図である。図5(a)、図6(a)、(b)において第1実施例と同じ構成要素については同一の符号を付してあり、その説明は適宜省略する。第1内蔵部品2、第2内蔵部品3が、結合することにより燃料タンクTの下面部Taと上面部Tbとにわたって鉛直状に立設される第1支柱4、第2支柱5から構成される点について、第2実施例は第1実施例と同じである。
図5(b)と図7(a)、(b)は第3実施例の説明図であり、図5(b)は内蔵部品の結合状態を示す全体側面図、図7(a)、(b)はそれぞれ内蔵部品の未結合状態、結合状態を示す部分側面図である。図5(b)、図7(a)、(b)において第2実施例と同じ構成要素については同一の符号を付してあり、その説明は適宜省略する。第1内蔵部品2、第2内蔵部品3が、結合することにより燃料タンクTの下面部Taと上面部Tbとにわたって鉛直状に立設される第1支柱4、第2支柱5から構成される点と、第1支柱4と第2支柱5とが結合状態となったときに一対のチューブが結合して連通する構造を備える点について、第3実施例は第2実施例と同じである。
図5(c)は第4実施例の内蔵部品の結合状態を示す全体側面図である。この第4実施例では、第2内蔵部品3にバルブVが設けられている。第1内蔵部品2を構成する第1支柱36と、バルブVを有した第2内蔵部品3を構成する第2支柱37とは、結合することにより燃料タンクTの下面部Taと上面部Tbとにわたって鉛直状に立設される。バルブVは、第2支柱37の内部に直接設けられた構造でもよいし、バルブV用のケーシングに設けられた構造でもよい。後者の構造の場合、例えばバルブV用のケーシングと第2支柱37とが一体に組み付けられて第2内蔵部品3を構成する。
図5(d)と図8(a)、(b)は第5実施例の説明図であり、図5(d)は内蔵部品の結合状態を示す全体側面図、図8(a)、(b)はそれぞれ内蔵部品の未結合状態、結合状態を示す部分側面図である。この第5実施例は、第1内蔵部品2と第2内蔵部品3とが結合することにより燃料タンクTの下面部Taと上面部Tbとにわたってダンパ機能を有する支柱が形成されることを特徴とする。
図9は第6実施例の説明図であり、(a)、(b)はそれぞれ内蔵部品の未結合状態、結合状態を示す部分側面図である。この第6実施例は、第1内蔵部品2と第2内蔵部品3の少なくとも一方の弾性変形を伴って両者を近接方向および離間方向の双方向において位置決め係合させる係合手段53を備える。第1内蔵部品2としての第1支柱51の先端には球状の係合凸部54が形成され、第2内蔵部品3としての第2支柱52の先端には狭小の間口を有した球状空間の係合凹部55が形成されている。前記係合手段53はこの係合凸部54と係合凹部55とから構成される。
図10は第7実施例の説明図であり、(a)、(b)はそれぞれ内蔵部品の未結合状態、結合状態を示す部分側面図である。この第7実施例も、第1内蔵部品2と第2内蔵部品3の少なくとも一方の弾性変形を伴って両者を近接方向および離間方向の双方向において位置決め係合させる係合手段53を備える。第6実施例の係合手段53が球状の係合凸部54と球状空間の係合凹部55とから構成されているのに対し、この第7実施例の係合手段53は係合爪64と係合孔65とから構成される。第1内蔵部品2としての第1支柱61の先端周りの側面には係合爪64が突設され、第2内蔵部品3としての第2支柱62の先端周りの側面には係合孔65が形成されている。
