Abstract
Description
本発明は、上記事情に鑑み、胴部の先端部を1つのシート部材で閉塞可能な軟質容器を提供することを目的とする。
前記胴部と接合された筒状の周側部と、
前記周側部から先端側へ向かってテーパ状に縮径する肩部と、
前記肩部の先端部を塞ぐ頂部と
を一体に有する一様な厚みの自立したフィルム成形体にて構成されていることを特徴とする。
これによって、先端シート部材単独で胴部の先端部を塞ぐことができる。先端シート部材を支持する支持体が不要であり、製品コストを低減できる。
流動体状の被収容物を吐出させる際は、例えば頂部に穴を開ける。肩部がテーパ状であることで、被収容物をスムーズに吐出できる。
前記周側部が、前記肩部へ向かって前記肩部より緩やかに縮径するテーパ状であることが好ましい。これによって、先端シート部材を成形装置から容易に型抜きできる。
前記頂部が、前記肩部から先端側へ凸をなすドーム状であることが好ましい。これによって、被収容物による内圧に対する耐圧性を高めることができる。加えて、デザイン性を高めることができる。
更に、前記肩部と前記頂部とが滑らかに連続していることが好ましい。これによって、肩部と頂部の連続部に大きな応力が掛かるのを防止できる。
頂部に穴を開けたうえで、底シート部材をプランジャ代わりにして先端シート部材へ向けて押すことで、被収容物を吐出させることができる。これに伴い、胴部が潰れる。最終的には、底シート部材が先端シート部材の内面側に嵌ることで、被収容物を出し切ることができる。したがって、被収容物の無駄を少なくできる。
これによって、先端シート部材を先端延出部内に封入できる。したがって、先端シート部材を手で直接、触れないようにしたり、空気中の細菌や塵埃が先端シート部材に付着するのを防止したりでき、衛生を向上できる。先端シート部材に多少の凹みが出来ていたとしても、先端延出部によって先端シート部材を覆うことで、外観上、見栄えを損なわないようにできる。
これによって、吐出口部材が先端シート部材によって支持される。吐出口部材は、胴部に達している必要がない。したがって、吐出口部材が先端シート部材の支持体となる構造(特許文献1~3等)よりも、吐出口部材を小さくできる。その分、材料コストを低減できる。
凸状の絞り型部を有して、ブランクフィルムから前記先端シート部材を絞り成形するシート成形部と、
前記絞り型部と対向して、前記絞り型部上の先端シート部材との間にキャビティを画成するとともに、前記キャビティに前記吐出口部材の材料を射出することによって、前記吐出口部材を射出成形する吐出口成形部と、を備えたことを特徴とする。
1つの装置によって先端シート部材及び吐出口部材を製造でき、製造コストを低減できる。
シート成形部によって、ブランクフィルムから前記先端シート部材を絞り成形する絞り工程と、
前記シート成形部に保持されたままの先端シート部材と、その先端側に対向する吐出口成形部との間にキャビティを画成し、前記キャビティに前記吐出口部材の材料を射出する射出成形工程と、
を備えたことを特徴とする。
先端シート部材及び吐出口部材をほぼ同時に製造でき、製造コストを低減できる。
そこで、本発明は、軟質容器の柔軟な胴部の先端部に先端シート部材の周側部を接合する軟質容器製造装置であって、
先端に前記先端シート部材が被せられ、前記先端に続く外周に前記胴部が被せられ、かつ先端近傍の外周において前記先端シート部材の周側部と前記胴部の先端部とが重ねられるコアと、
前記コアにおける前記先端近傍のコア部分を前記接合時に拡径させるコア駆動手段と、
前記コア部分の外周上に溶着エネルギーを供給する溶着ヘッドと
を備えたことを、更なる特徴とする。
前記被せた後、コア駆動手段によって前記先端近傍のコア部分を拡径させる。このため、先端シート部材の周側部と胴部の先端部との重なり部分に前記コア部分が内周側から押し当てられる。これによって、前記クリアランスを解消できる。すなわち、先端シート部材の周側部と胴部の先端部との間に隙間ができるのを防止できる。その状態で、前記コア部分の外周上における先端シート部材の周側部と胴部の先端部との重なり部分に溶着ヘッドから溶着エネルギーが供給される。これによって、先端シート部材の周側部と胴部の先端部とを隙間なく溶着して接合できる。
その後、前記コア部分を縮径させ、先端シート部材及び胴部を含む軟質容器をコアから抜く。
溶着ヘッドは、高周波溶着コイルを含む高周波溶着ヘッドであることが好ましい。
前記接合時にはコア駆動手段によって内周押え部材を径方向外側へ前進させる。これによって、前記コア部分が拡径され、先端シート部材と胴部がしっかりと接合される。
前記接合後、コア駆動手段によって内周押え部材を径方向内側へ後退させる。これによって、前記コア部分が縮径され、軟質容器をコアから抜くことができる。
前記コア駆動手段は、複数の内周押え部材を互いに同期させて進退させることが好ましい。
前記コア駆動手段が、コアの軸線上に配置された駆動軸と、前記駆動軸を前記軸線に沿って前進位置と後退位置との間でスライドさせる駆動部と、前記駆動軸と前記内周押え部材との間に設けられたカム機構と、前記内周押え部材を縮径方向へ付勢する内周付勢手段とを備え、前記駆動軸が前記前進位置へスライドされると前記カム機構によって内周押え部材が径方向外側へ前進され、前記駆動軸が前記後退位置へスライドされると前記内周付勢手段によって前記内周押え部材が径方向内側へ後退されるようになっていることが好ましい。
前記カム機構として、例えば前記駆動軸の先端部に先細テーパなどの凸状のカム面が形成され、かつ前記内周押え部材の内面には、前記テーパ部と当接する凹状のカム面が形成されていることが好ましい。
これによって、先端シート部材と胴部の重なり部分を前記コア部分と外周押え部材とで挟み付けることができる。したがって、先端シート部材と胴部との間に隙間ができるのを確実に防止でき、両者をしっかりと接合できる。かつ、外周押え部材によって軟質容器の外径を規定することで、寸法精度を高めることができる。特に先端シート部材と胴部の重なり部分の径寸法を安定させることができる。
1の環状の外周押え部材によって前記コア部分が囲まれていてもよく、複数の外周押え部材が前記コア部分のまわりに互いに環状に配置されることで、これら複数の外周押え部材によって前記コア部分が囲まれていてもよい。
前記複数の外周押え部材が、前記コア部分の径方向に進退可能であるが好ましい。
前記突起が前記胴部の封筒貼り部又は合掌貼り部を横切るようにすることで、封筒貼り部又は合掌貼り部の長手方向に細長く延びる貼り部内隙間の一箇所を局所的に押し潰し、更には溶着して塞ぐことができる。これによって、軟質容器の内部空間が前記貼り部内隙間を介して外部と連通するのを防止できる。ひいては、内容物が前記貼り部内隙間を通して漏れ出たり外気が前記貼り部内隙間を通して軟質容器内に入り込んだりするのを防止できる。
前記突起は、前記外周押え部材の内側面における、前記封筒貼り部又は合掌貼り部と対面する部分及びその周辺部に少なくとも設けられていればよい。
<第1実施形態>
図1~図4は、本発明の第1実施形態を示したものである。図1(a)~(c)に示すように、軟質容器1は、胴部10と、先端シート部材20と、吐出口部材30を備えている。軟質容器1の被収容物9(内容物)は、例えば接着剤、塗料、飲料等の流動体や粘性体である。
図1(a)及び同図(b)に示すように、被収容物9の充填後、胴部10の底部がヒートシールによって塞がれ、底部ヒートシール部12が形成される。
なお、胴部10の積層フィルム数、各層の厚み、材質、シール構造等は、必ずしも前記のものに限られず、適宜改変できる。
周側部21は、断面円形の筒状になっている。詳しくは、周側部21は、先端側(肩部22の側)へ向かって非常に緩やかに縮径するテーパ状になっている。周側部21のテーパ角度θ21は、胴部10のテーパ角度に合わせられており、例えば、軟質容器1の軸線L1に対して好ましくはθ21=0.1°~0.5°程度、より好ましくはθ21=0.3°程度になっている。
周側部21に胴部10の先端部が接合されている。詳しくは、胴部10の先端部が周側部21の外周面に被さり、かつ胴部10と周側部21とが溶着されている。ここでは、溶着方法として高周波溶着が用いられているが、必ずしもこれに限られるものではなく、超音波溶着や熱溶着等の他の溶着方法を用いてもよい。
肩部22の先端部(中央部)が頂部23によって塞がれている。頂部23は、肩部22と滑らかに連続するとともに先端側へ凸をなすドーム状(部分球面状)になっている。
なお、フィルム成形体28ひいては先端シート部材20の積層フィルム数、各層の厚み、材質等は、必ずしも前記に限られず、適宜改変できる。
鍔部32の外径ひいては吐出口部材30の外径は、胴部10の先端部の内径より小径である。吐出口部材30は、胴部10と直接には接しておらず、先端シート部材20を介して胴部10と接続されている。
吐出口部31の基端側(図2(a)において下側)の開口は、頂部23によって塞がれている。ドーム状の頂部23が吐出口部31の内部に少し入り込んでいる。
<成形装置50(軟質容器製造装置)>
図3に示すように、軟質容器1における先端シート部材20及び吐出口部材30は、成形装置50(軟質容器製造装置)によって作製される。図3(a)に示すように、成形装置50は、第1金型51と、第2金型52と、第3金型53を含む。これら金型51~53が、下から上へ順次配置されている。
第1金型51は、凸状の絞り型部51bを有している。絞り型部51bの先端部(上端部)は、先端シート部材20の形状に合わせた円錐面状になっている。第2金型52に環状凹部からなるシートセット部52cが形成されている。主に第1金型51と第2金型52によって、シート成形部50bが構成されている。
第3金型53は、円錐凹面状の絞り受部53bと、ネジ溝付きの円筒凹面状の射出型部53dを有している。絞り受部53bの中央部に射出型部53dが設けられている。
第3金型53の上部にトッププレート54が配置されている。トッププレート54の中央部に射出ノズル55が設けられている。射出ノズル55が、円筒凹面状の射出型部53d内に挿し入れられている。
主に第3金型53と射出ノズル55とによって、吐出口成形部50cが構成されている。シート成形部50bの先端側(上側)に吐出口成形部50cが対向配置されている。
なお、第3金型53は、複数(図3では左右2つ)のピース53aに分割されている。これらピース53aが、射出ノズル55を中心にして離間したり接近したりすることで、第3金型53が開閉可能になっている。
図3(a)に示すように、先端シート部材20となるべき円板形状のブランクフィルム29(成形前フィルム)を、シートセット部52cにセットする。第2金型52と第3金型53を接近させ、第3金型53のシート押え部53cによってブランクフィルム29の外周部を押さえる。
続いて、図3(b)に示すように、第1金型51と第2金型52とを接近させて型締めする。型締めによって、絞り型部51bが、シートセット部52cの中心穴から突出して、ブランクフィルム29を絞り変形させながら、絞り受部53b内に入り込む。これによって、シート成形部50bによって、ブランクフィルム29からフィルム成形体28ひいては先端シート部材20が絞り成形される。
バリア層25を胴部10のバリア層15よりも厚肉(好ましくはθ25=30μm~50μm程度、より好ましくはθ25=40μm程度)にしておくことで、絞り成形時にバリア層25が破れるのを防止できる。ちなみに、バリア層25がバリア層15と同程度の厚み(例えばθ25=10μm~15μm程度)であると、絞り成形時に破れやすい。
先端シート部材20が絞り成形されるのと同時に、該先端シート部材20と、その上方(先端側)の射出型部53dの内面及び射出ノズル55の外周面との間に、キャビティ50dが画成される。かつ、絞り受部53bが肩部22に当たり、射出ノズル55の下端面が頂部23に当たる。
続いて、図3(c)に示すように、シート成形部50bによって先端シート部材20を保持したまま、溶融樹脂39(吐出口部材30の材料)を射出ノズル55の射出路55aからキャビティ50dに射出する。これによって、先端シート部材20の絞り成形と同時又はその直後に吐出口部材30を射出成形できる。しかも、射出成形と同時に、溶融樹脂39の接着性によって吐出口部材30を先端シート部材20と一体接合できる。
その後、金型51~53を互いに離して型締めを解除し、吐出口部材30付き先端シート部材20を脱型する。周側部21が緩やかなテーパ状であるため、先端シート部材20を容易に型抜きできる。
これによって、先端シート部材20及び吐出口部材30が作製される。1つの成形装置50によって先端シート部材20及び吐出口部材30を効率的に製造でき、製造コストを低減できる。
詳しくは、図4(a)に示すように、接合用治具として心金61を用意する。心金61は、円柱状であり、かつ先端側(上側)へ向かって緩やかに縮径されている。
心金61の先端部(上端部)に先端シート部材20(吐出口部材30付き)を被せる。
次に、胴部10を上方から心金61の外周に被せる。これによって、胴部10の先端部(上端部)が、周側部21の外周部に被さる。胴部10及び周側部21を共にテーパ状に形成しておくことで、胴部10を周側部21の全周にわたってぴったりと接するようにできる。
次に、図4(b)に示すように、環状の高周波溶着装置60を心金61の先端部の外側にセットし、胴部10の先端部と周側部21とを高周波溶着する。
その後、軟質容器1を心金61から外す。
これによって、軟質容器1(被収容物9は未充填)を作製できる。
吐出口部材30の鍔部32は、胴部10に達している必要がなく、吐出口部材30が先端シート部材20の支持体となる構造(特許文献1~3等)よりも吐出口部材30を小さくできる。その分、材料コストを低減できる。
被収容物9が未充填の軟質容器1は底部が開放されている。この底部開口から内部に他の軟質容器1を挿し入れることができる。胴部10が僅かにテーパ状になっているため、挿し入れ操作を容易化できる。更には複数の軟質容器1,1…を順次一列に挿し入れて束ねることで、コンパクト化できる(図6(a)参照)。これによって、複数の軟質容器1,1…の保管スペースを小さくでき、搬送等を効率化できる。
肩部22と頂部23とが滑らかに連続していることによって、これらの肩部22と頂部23の連続部分に大きな応力が掛かるのを防止できる。また、頂部23をドーム状にすることによって、被収容物9による内圧に対する耐圧性を高めることができる。更に、デザイン性を高めることができる。
開穿した軟質容器1を例えば吐出ガンにセットし、吐出ガンのプランジャで胴部10を軸方向に押し潰す。これによって、被収容物9が頂部23の開穿部を経て吐出口部材30から吐出される。肩部22がテーパ状であることで、被収容物9をスムーズに吐出できる。
<第2実施形態>
図5は、本発明の第2実施形態を示したものである。図5に示すように、第2実施形態の軟質容器1Bには、吐出口部材30が設けられていない。先端シート部材20の肩部22及び頂部23の外面全体が、軟質容器1Bの外部に面している。
図6に示すように、第2実施形態においては、軟質容器1Bの底部(図6(a)において下端)の開放部から内部に、他の軟質容器1Bを挿し入れる場合、これら軟質容器1B,1Bの先端シート部材20,20どうしがほぼ重なるまで、深く挿し入れることができる。したがって、複数の軟質容器1B,1B…を順次一列に挿し入れて束ねることで、これら複数の軟質容器1B,1B…を一層コンパクトな状態で保管、搬送等することができる。
図7は、本発明の第3実施形態を示したものである。図7(b)に示すように、第3実施形態の軟質容器1Cの先端シート部材20には、第1実施形態(図1)の吐出口部材30に代えて、環状(リング状)の吐出口部材30Cが設けられている。図7(a)に示すように、吐出口部材30Cは、肩部22の外面に接合されることよって先端シート部材20に支持されている。吐出口部材30Cの外径は胴部10の先端部の内径より十分小さい。吐出口部材30Cは、胴部10と直接には接してない。また、吐出口部材30Cの高さ(図7(a)において上下方向の寸法)は、第1実施形態(図2(a))の吐出口部材30よりも十分に小さい。図示は省略するが、吐出口部材30Cに吐出ガンのノズルが接続可能になっている。
吐出口部材30C付き先端シート部材20は、第1実施形態と同様の方法で製造することができる。
図8~図9は、本発明の第4実施形態を示したものである。図8(a)に示すように、第4実施形態の軟質容器1Dにおいては、被収容物9を充填した後の胴部10の底部に底シート部材40が設けられている。底シート部材40によって胴部10の底部が塞がれている。底シート部材40は、先端シート部材20とほぼ同一形状になっている。つまり、底シート部材40は、緩テーパ状の周側部41と、急テーパ状の肩部42と、ドーム状の頂部43を一体に有している。かつ、底シート部材40は、第2フィルム成形体48によって構成されている。第2フィルム成形体48は、全体的に一様(均一)な厚みを有し、かつ自立している。第2フィルム成形体48は、フィルム成形体28と同様に、絞り成形によって作製できる。
更に、図8(b)に示すように、フィルム成形体48ひいては底シート部材40は、先端シート部材20と同一のラミネート構造になっている。つまり、底シート部材40は、直鎖状低密度ポリエチレン(LLDPE)からなる外層44と、ポリエチレンテレフタレート(PET)からなる内層46と、アルミニウムからなる中間のバリア層45とを含む。バリア層45の厚み等はバリア層25と同様である。
なお、底シート部材40の積層フィルム数、各層の厚み、材質等は、必ずしも前記に限られず、適宜改変できる。また、底シート部材40の形状及び大きさが先端シート部材20と多少違っていてもよい。
図10及び図11は、本発明の第5実施形態を示したものである。図10(a)及び図10(b)に示すように、第5実施形態の軟質容器1Eにおいては、胴部10を構成するシート19の先端側の部分(同図において上側部分)が、先端シート部材20及び吐出口部材30よりも先端側(同図において上側)へ延び出ており、先端延出部11を構成している。
先端延出部11の基端部(同図において下端部)は、先端シート部材20の外周に沿うように円形になるとともに胴部10と一体に連なっている。
先端延出部11の先端部(同図において上端部)は、周方向の一側部と他側部が重ね合わされてヒートシールされることによって封止され、封止部13となっている。先端シート部材20と封止部13との間の先端延出部11の内部空間11dが密封されている。
封止部13の一側縁(図10(a)において左側縁)における底辺部近くには、切込み13eが形成されている。
更に、封止部13には、フック孔13f(ハトメ)が形成されている。フック孔13fにフック等を通すことで、軟質容器1Eを吊り下げて保管することができる。
更に、軟質容器1Eにおいては、先端シート部材20に多少の凹みが出来ていたとしても、先端延出部11によって先端シート部材20を覆うことで、外観上、見栄えを損なうのを防止できる。
なお、ノズル2を付けたまま、該ノズル2の先端口をフィルム巻き付け等によって塞いでもよい。
図12~図20は、本発明の第6実施形態を示したものである。
<封筒貼り軟質容器1F>
図17及び図18は、軟質容器1Fを、底部が未封止状態(開放状態)で、内容物が未充填の状態で示したものである。軟質容器1Fは、胴部10と、先端シート部材20と、吐出口部材30を備えている。胴部10の底部開放部(図18において下端)から内容物が充填された後、前記底部開放部がヒートシールによって封止される。内容物は、例えば接着剤、塗料、飲料等の流動体や粘性体である。
先端シート部材20の外面にポリエチレン(PE)やポリプロピレン(PP)等の硬質樹脂からなる筒状の吐出口部材30が設けられている。吐出口部材30の内部通路の底部は、先端シート部材20の頂部23によって塞がれている。使用時は、頂部23に穴が開けられることで、内容物(被収容物)が吐出口部材30から吐出される。
図12に示すように、先端シート部材20と胴部10とは、高周波溶着装置60F(軟質容器製造装置における接合装置部分)によって接合される。高周波溶着装置60Fは、コア61Fと、外周押え部材62と、溶着ヘッド63を備えている。
トップコア65の外周には、ゴム製の環状弾性部材68が装着されている。各内周押え部材66の外周面には、環状弾性部材68を収容する溝66dが周方向に延びるように形成されている。好ましくは、環状弾性部材68は、自然状態よりも少し拡径されて張力が働いている状態で溝66dに収容されている。このため、内周押え部材66には、環状弾性部材68からの径方向内側への力が常時かかっている。例えば環状弾性部材68としては、シール材として一般的なOリングを転用できる。
トップコア65の内周面には、円錐凹面状のカム面65eが形成されている。各内周押え部材66におけるカム面65eは、半割り円錐凹面状である。テーパ部69eがカム面65eに当たっている。
テーパ部69eとカム面65eとによってカム機構が構成されている。言い換えると、駆動軸69と内周押え部材66との間にカム機構69e,65eが設けられている。
図15(a)に示すように、駆動軸69を上昇させて前進位置にすると、テーパ部69eとカム面65eとのカム作用によって、内周押え部材66が径方向外側へ押し動かされる。したがって、トップコア65が拡径される。これに伴って、連結板67のトップコア65側の端部が外側へ反るように、連結板67が弾性変形される。かつ環状弾性部材68が、拡径方向へ弾性変形される。
なお、図15(a)においてトップコア65の拡径度合は誇張されている。
駆動軸69、軸駆動部71、連結板67及び環状弾性部材68によって、コア駆動手段が構成されている。更に連結板67及び環状弾性部材68は、内周付勢手段を構成している。
軟質容器1Fの製造方法を、胴部10と先端シート部材20との接合方法を中心に説明する。
胴部10と先端シート部材20を別々に作製する。好ましくは胴部10の先端部と先端シート部材20の周側部21との間に一定のクリアランス(寸法差による隙間)が出来るように、胴部10及び先端シート部材20を作製する。
先端シート部材20には吐出口部材30を接合する。好ましくは、先端シート部材20を樹脂シート材から絞り成形するのと同時に、吐出口部材30を前記樹脂シート材上で射出成形する。これによって、吐出口部材30と先端シート部材20とを、これらの成形と同時に一体的に接合する。
高周波溶着装置60Fにおいては、駆動軸69を後退位置にして、トップコア65を平常径にしておく。また、外周押え部材62及び溶着ヘッド63を退避させておく。
そして、前記吐出口部材30付きの先端シート部材20をコア61Fの先端に被せる。
続いて、コア61Fの先端の下方に続く外周に胴部10を被せる。かつトップコア65の外周上(コア61Fの先端近傍の外周上)において、先端シート部材20の周側部21の外周側に胴部10の先端部を重ねる。
トップコア65を平常径にしておくことによって、先端シート部材20及び胴部10をコア61Fに確実に被せることができる。しかも、胴部10の先端部と先端シート部材20の周側部21との間にクリアランスが設けられることによって、先端シート部材20の周側部21の外周に胴部10の先端部を容易に被せることができる。胴部10を被せる際に胴部10が破けるのを防止できる。
胴部10の封筒貼り部10dは、突起62d付きの外周押え部材62Aの方向へ向けておく。
その後、外周押え部材62及び溶着ヘッド63を図12に示す規定の位置にセットする。
さらに、3つの外周押え部材62を3方向からエアシリンダなどの外周押え駆動部72によって径方向内側へ弾性的に付勢する。
これによって、先端シート部材20の周側部21と胴部10の先端部との重なり部分1dが、全周にわたって外周押え部材62と内周押え部材66との間に強く挟み付けられる。この結果、先端シート部材20の周側部21と胴部10の先端部とが全周にわたってぴったりと接し、前記クリアランスが解消される。
これによって、軟質容器1Fが作製される。
また、外周押え部材62によって、先端シート部材20と胴部10の重なり部分1dの径寸法を安定させることができ、軟質容器1Fの寸法精度を高めることができる。
また、外周押え部材62及び溶着ヘッド63を退避させる。
そして、軟質容器1Fをコア61Fから上方へ引き抜いて取り出す。胴部10及び先端シート部材20の周側部21をわずかに先細のテーパ状に形成しておくことで、コア61Fからの引き抜き操作を容易化できる。
図19及び図20は、軟質容器の変形例を示したものである。
図19に示すように、当該軟質容器1Gにおいては、胴部10を構成するシート19の両端部19e,19fが合掌貼りされている。このため、図20(a)に示すように、先端シート部材20及び胴部10をコア61Fに被せた段階では、両端部19e,19fにおける付け根どうし間と、先端シート部材20の周側部21の外周面との間に貼り部内隙間10eが形成される。
例えば、頂部23が平らであってもよい。
シート成形体28の樹脂層の厚みや材質等の選択によって自立性を確保してもよい。
複数の実施形態を互いに組み合わせてもよい。例えば、第4実施形態(図8~図9)の底シート部材40を第2実施形態(図5~図6)又は第3実施形態(図7)に適用してもよい。第5実施形態(図10)の先端延出部11を第2実施形態(図5~図6)又は第3実施形態(図7)に適用してもよい。
胴部10及び先端シート部材20のフィルム構造、材質、製造方法は適宜改変できる。先端シート部材20の周側部21と胴部10との接合方法として高周波溶着が用いられているが、必ずしもこれに限られるものではなく、超音波溶着や熱溶着等の他の溶着方法を用いてもよい。胴部10の先端部の外周面に先端シート部材20の周側部21が被さって接合されるようになっていてもよい。コアが加熱され、その熱がコアの外周上の重なり部分1dに伝わり、重なり部分1dが溶着されるようになっていてもよい。
外周押え部材が、複数に分割されていない環状体であってもよい。外周押え部材を省略してもよい。外周押え部材の突起62dを省略してもよい。
