In addition, when the reduced pressure absorption function by the movable wall portion 222 is sufficient, the movable wall portion 222 can be preferentially displaced under reduced pressure to suppress (prevent) the deformation of the panel portion 251. In this case, for example, the rib width D1 can be formed as large as possible, and it is possible to more reliably prevent appearance defects from occurring on the label.
- the absorption capacity of samples 21 to 27 are 27.4 (ml) for sample 21, 27.3 (ml) for sample 22, 27.2 (ml) for sample 23, and 26.9 for sample 24, respectively.
- sample 25 is 26.6 (ml)
- sample 26 is 25.2 (ml)
- sample 27 is 22.2 (ml).
- the ratio of the rib width D1 to the panel width D2 is 38.5% or less, the absorption capacity of 26 (ml) or more is maintained while suppressing the appearance failure of the label. And was able to demonstrate sufficient vacuum absorption performance.
- the ratio of the rib width D1 to the panel width D2 is reduced (as the rib width D1 is reduced), although the sufficient reduced pressure absorption performance can be exhibited at the time of pressure reduction, the appearance is significantly reduced.
- the rib width D1 is reduced, the support portion of the label is reduced in the panel portion 251, so that the interval between the rib 255 and the pillar portion 252 is increased, and the label wound around the body portion 213 is attached to the panel portion 251. It is thought that it became easy to move to the inner side in the radial direction toward the bottom wall portion 253. Specifically, in the sample 21, no deterioration in appearance was observed when the shrink label was attached.
- the ratio of the rib width D1 to the panel width D2 was less than 10%, the appearance of the attached shrink label was deteriorated.
- the number and arrangement of the panel portions 251 and the column portions 252 can be appropriately changed in consideration of the strength required for the bottle 201, the reduced pressure absorption capacity, and the like.
- the cross-sectional view shape along the radial direction of each of the shoulder portion 212, the trunk portion 213, and the bottom portion 214 is a circular shape. May be.
- the rib 255 is disposed with a gap around the entire circumference between the rib 255 and the side wall 254.
- the present invention is not limited to this, and the rib 255 may be provided with a gap at least between the vertical side wall portion 254a.
- the present invention is not limited to this, and a plurality of ribs 255 may be provided.
- the synthetic resin material forming the bottle 201 may be appropriately changed, for example, polyethylene terephthalate, polyethylene naphthalate, amorphous polyester, or a blend material thereof.
- the bottle 201 is not limited to a single layer structure, and may be a laminated structure having an intermediate layer. Examples of the intermediate layer include a layer made of a resin material having a gas barrier property, a layer made of a recycled material, or a layer made of a resin material having an oxygen absorbing property.
Abstract
Description
この構成によれば、例えば、ボトルに密封された内容物の温度が低下してボトル内が減圧した場合等に、パネル部が径方向の内側に向けて優先的に変形することで、ボトルのうちパネル部以外の部分での変形を抑えつつ、ボトル内の減圧を吸収するように構成されている。
しかし、特許文献1に記載された従来の技術では、パネル部が径方向の内側に向けて凹設されている。このため、特にシュリンクラベルを用いた場合に、平面視において円形状のボトルであっても、胴部におけるラベルの装着状態が、柱部を覆う部分が角部、パネル部を覆う部分が辺部となるような略多角形状となる。
しかも、第一の態様によれば、パネル底壁部に径方向の外側に向けて突出するリブを配設した。このため、パネル部を覆うように胴部に取り付けられるラベルを、径方向の内側から支持することができる。そのため、ラベル装着時において、パネル部を覆うラベルが径方向の内側へ移動するのを規制できる。これにより、ラベルがパネル部の内側に引き込まれるのを抑制し、ラベルに外観不良が発生するのを抑制できる。また、減圧時にパネル部が径方向の内側に向けて変形した場合であっても、上述したラベルの変位は抑制される。その結果、所望の減圧吸収性能を維持した上で、胴部に取り付けられるラベルに外観不良が発生するのを抑制できる。
また、パネル部を周方向に4つ以上形成することで、胴部における周方向の異なる視点ごとで視認可能なラベルの周長が異なるのを抑制することが可能になる。この結果、胴部に巻き付けられるラベルの外観に違和感を与えず、良好に保つことができる。
そして、リブ及び柱部によって胴部におけるラベルの支持面積を確保できるので、ラベルの外観に違和感が生ずるのを確実に抑制できる。
したがって、ラベルの外観に違和感が生ずるのを抑えつつ、胴部に減圧吸収性能を具備させることができる。
特に、上記構成によれば、リブがパネル底壁部におけるボトル軸方向の全長に亘って形成されているので、径方向から見てリブと重なる部分では、ラベルをボトル軸方向の全体に亘って支持できる。これにより、ラベルにしわが発生するのを確実に抑制できる。
さらに、リブ及び柱部によって胴部におけるラベルの支持面積を確保できるので、ラベルの外観に違和感が生ずるのを確実に抑制できる。
以下、図面を参照し、本発明の第1実施形態に係るボトルを説明する。本実施形態に係るボトル1は、図1~図4に示されるように、口部11、肩部12、胴部13及び底部14を備える。本実施形態に係るボトル1は、これら口部11、肩部12、胴部13及び底部14が、それぞれの中心軸線を共通軸上に位置し、この順に連設された概略構成を有する。
本実施形態に係るボトル1は、合成樹脂材料で一体に形成されており、射出成形により有底筒状に形成されたプリフォームが、ブロー成形されて形成されている。また、口部11には、図示しないキャップが装着される。さらに、口部11、肩部12、胴部13及び底部14はそれぞれ、径方向に沿う横断面視形状が略円形状を有する。なお、本実施形態のボトル1の内容量は、280ml以上1000ml以下である。
胴部13は筒状に形成され、肩部12の下端に連なり下方に向けて延在している。胴部13のうち、ボトル軸O方向の両端部同士の間の中間部13aは、両端部よりも小径である。なお、胴部13の中間部13aには、図示しない例えばシュリンクラベル等のラベルが巻き付けられるように構成されている。
下ヒール部27は、上ヒール部28よりも小径に形成され、連結部29は、上方から下方に向かうに従い漸次縮径された構成を有する。
上ヒール部28は、胴部13のボトル軸O方向の両端部とともに、ボトル1の外径が最も大きい最大外径部である。また、上ヒール部28におけるボトル軸O方向に沿う中間部分には、第2環状凹溝31が全周に亘って連続して形成されている。
また、可動壁部22には、複数のリブ41がボトル軸Oを中心に放射状に配設されている。リブ41は、上方に向けて曲面状に窪む複数の凹部41aが径方向に沿って断続的に配設された構成を有する。
環状段部23cは、径方向の外側に向けて窪む凹曲面状に形成されている。環状段部23cは、立ち上がり周壁部21の上端部よりも上方、もしくは同等の高さに位置している。
また、張出部23d同士の間の部分23eは、底面視において径方向の外側に向けて突出する曲面状に形成され、周方向で隣り合う張出部23dの周方向に沿う端部同士をそれぞれ連結している。
頂壁部55aは、径方向に沿う横断面視(図2参照)において、径方向の外側に向けて突出する曲面状に形成されている。頂壁部55aは、実質的に複数の柱部52における各頂部52aの表面形状に倣って周方向に延びる仮想円L上に位置し、胴部13における中間部13aの最大外径部である。
しかも、縦側壁部54aにおける径方向の内端、及び周端壁部55bにおける径方向の内端の径方向に沿う位置が互いに異なっているため、隙間56が変形し易くなり、減圧吸収性能を確実に具備させることができる。
これにより、隙間56以外の部位(例えば、柱部52やリブ55、肩部12)での変形を抑えつつ、ボトル1の内圧変化(減圧)を吸収できる。
しかも、リブ55がパネル底壁部53におけるボトル軸O方向の全長に亘って形成されている。このため、径方向から見てリブ55と重なる部分では、ラベルをボトル軸O方向の全体に亘って支持できる。これにより、ラベルにしわが発生するのを確実に抑制できる。
さらに、リブ55及び柱部52によって胴部13におけるラベルの支持面積を確保できるので、ラベルの外観に違和感が生ずるのを確実に抑制できる。
また、可動壁部22による減圧吸収機能が十分である場合、ボトル1内の減圧時にこの可動壁部22を優先的に変位させ、隙間56の変形を抑制(防止)するように構成することもできる。この場合は、例えばリブ幅D1を可能な限り大きく形成することができ、より確実にラベルに外観不良が発生することを防止できる。
図2、図5~図10は実施例1~7のサンプルボトル(以下、サンプル1~7という)を示し、図11は比較例のサンプルボトル(以下、サンプル8という)を示している。
図2に示すサンプル1は、上述した本実施形態と同様の構成からなるボトル1である。そして、以下にはサンプル1を基準とし、サンプル1と、各サンプル2~8と、の主な違いを説明する。
図5に示すサンプル2は、パネル部51のリブ幅D1がサンプル1に対して小さい。
図6に示すサンプル3は、周端壁部55bの深さH2がサンプル1に対して小さく、縦側壁部54aの深さH1と、周端壁部55bの深さH2と、の差がサンプル1に対して小さい。
図7に示すサンプル4は、縦側壁部54aの深さH1がサンプル1に対して小さく、縦側壁部54aの深さH1と、周端壁部55bの深さH2と、の差がサンプル1に対して大きい。
図8に示すサンプル5は、パネル部51のリブ幅D1がサンプル1に対して大きい。
図9に示すサンプル6は、柱部52の柱幅D2がサンプル1に対して大きく、パネル部51のリブ幅D1よりも大きい。この場合、リブ55のうち、仮想円L上に位置する部分の長さd1と、柱部52のうち、仮想円L上に位置する部分の長さd2と、は同等の長さを有する。
図10に示すサンプル7は、同一のパネル部51における周方向の両側に位置する縦側壁部54a同士のなす角度θ1がサンプル1に対して大きい。
図11に示すサンプル8(比較例)は、縦側壁部54aの深さH1と、周端壁部55bの深さH2と、が同等である。
一方、深さH1は、径方向に沿う横断面視において、縦側壁部54aの延長線及び接続部分53aの延長線の交点と、仮想円Lと、の径方向の長さである。深さH2は、径方向に沿う横断面視において、周端壁部55bの延長線及び接続部分53aの延長線の交点と、仮想円Lと、の径方向の長さである。
図13に示すように、本検証で用いたサンプルAのボトルA1は、胴径φ(仮想円Lの外径)が70mm、周方向における凸部57の幅が10mm(リブ幅D1=柱幅D2=10mm)とされ、等間隔で配置されたこれら凸部57間に隙間56が設けられている。また、図13に示すボトルA1は、凸部57が併せて5本形成されている。そして、胴部13には、凸部57及び隙間56を覆うように全周に亘ってラベルSが巻き付けられている。
なお、サンプルB~Hについては、サンプルAに対して胴径φ、凸部幅(リブ幅D1及び柱幅D2)が同等で、凸部57の数を1本ずつ増加したものである。
(1)ラベル高低差T
ラベルSのうち凸部57を覆う部分からボトル軸Oまでの径方向に沿う長さR1(仮想円L及び胴径φの半径に相当)と、ラベルSのうち隙間56を覆う部分からボトル軸Oまでの径方向に沿う長さR2と、の差。
(2)可視ラベル周長
胴部13における周方向の異なる視点ごとで、視認可能なラベルSの周長。
(3)可視ラベル幅
胴部13における周方向の異なる視点ごとで、視認可能な範囲のラベルSを径方向に投影した場合の幅。
特に、サンプルC~H(凸部57が7本以上)の場合には、ラベル高低差Tを2.00mm以下に抑えることができ、ラベルSの外観に違和感を与えず、良好に保つことができた。この場合、胴径φに対するラベル高低差Tを、3.0%以下(好ましくは2.0%以下)に抑えることで、胴径φの大きさに依らず外観を良好に保つことができる。
特に、サンプルC~H、すなわち凸部57が7本以上の場合には、可視ラベル周長差を20.00mm以下に抑えることができ、ラベルSの外観に違和感を与えず、良好に保つことができた。この場合、可視ラベル周長差を、サンプルIのラベル周長(全長)に対して10.0%以下に抑えることで、円形ボトルのラベル周長に依らず外観を良好に保つことができる。
また、凸部57の本数は、応力を均等に分散するため偶数とすることが好ましい。この場合、リブ55及び柱部52をそれぞれ偶数とすることがより好ましい。
また、上述した実施形態では、肩部12、胴部13及び底部14のそれぞれの径方向に沿う横断面視形状を円形状とした。しかし、これに限らず例えば、肩部12、胴部13及び底部14のそれぞれの径方向に沿う横断面視形状を多角形状にする等適宜変更してもよい。
さらに、上述した実施形態では、リブ幅D1が柱幅D2以上になっている場合について説明した。しかし、これに限らず、サンプル6のように柱幅D2がリブ幅D1より大きくても構わない。
さらに、ボトル1は単層構造体に限らず中間層を有する積層構造体としてもよい。この中間層としては、例えばガスバリア性を有する樹脂材料からなる層、再生材からなる層、若しくは酸素吸収性を有する樹脂材料からなる層等が挙げられる。
以下、図面を参照し、本発明の第2実施形態に係るボトルを説明する。
本実施形態に係るボトル201は、図14~17に示されるように、口部211、肩部212、胴部213及び底部214を備える。これら口部211、肩部212、胴部213及び底部214が、それぞれの中心軸線を共通軸上に位置し、この順に連設された概略構成を有する。
本実施形態に係るボトル201は、射出成形により有底筒状に形成されたプリフォームがブロー成形されてなり、合成樹脂材料で一体に形成されている。また、口部211には、図示しないキャップが装着される。さらに、口部211、肩部212、胴部213及び底部214はそれぞれ、径方向に沿う横断面視形状が略円形状を有する。
胴部213は筒状に形成され、肩部212の下端に連なり下方に向けて延在している。胴部213のうち、ボトル軸O方向の両端部同士の間の中間部213aは、両端部よりも小径である。なお、胴部213の中間部213aには、図示しない例えばシュリンクラベル等のラベルが巻き付けられるように構成されている。
下ヒール部227は、上ヒール部228より小径に形成され、連結部229は、上方から下方に向かうに従い漸次縮径された構成を有する。
上ヒール部228は、胴部213のボトル軸O方向の両端部とともに、ボトル201の外径が最も大きい最大外径部である。また、上ヒール部228におけるボトル軸O方向に沿う中間部分には、第2環状凹溝231が全周に亘って連続して形成されている。
また、ヒール部217の外周面、及び胴部213の下端部の外周面には、例えばシボ加工等により突出高さの低い凹凸部217aが形成されている。
また、可動壁部222には、複数のリブ241がボトル軸Oを中心に放射状に配設されている。リブ241は、上方に向けて曲面状に窪む複数の凹部241aが径方向に沿って断続的に配設された構成を有する。
図16及び図17に示すように、下筒部223aは、下方に向けて突出する曲面部226を介して、可動壁部222の径方向の内端部に連結されている。なお、この曲面部226は、径方向の内側を向く斜め下方に向けて突出している。また下筒部223aは、径方向に沿う横断面視で円形状に形成されている。
環状段部223cは、径方向の外側に向けて窪む凹曲面状に形成されている。環状段部223cは、立ち上がり周壁部221の上端部よりも上方、もしくは同等の高さに位置している。
また、張出部223d同士の間の部分223eは、底面視において径方向の外側に向けて突出する曲面状に形成され、周方向で隣り合う張出部223dの周方向に沿う端部同士をそれぞれ連結している。
一方で、側壁部254には、一対の横側壁部254bがボトル軸O方向の両端に位置して周方向に延びるように設けられている。一対の横側壁部254bは、径方向の内側から外側に向けて延設されている。
また、頂面255aにおける中間部213aの接線方向に沿うリブ幅D1は、パネル部251における中間部213aの接線方向に沿うパネル幅D2の10%以上38.5%以下に設定されている。
しかも、本実施形態では、底壁部253に径方向の外側に向けて突出するリブ255を形成したため、パネル部251を覆うように胴部213に巻き付けられるラベルを、径方向の内側から支持することができる。そのため、ラベル装着時において、パネル部251を覆うラベルが径方向の内側へ移動するのを規制できる。これにより、ラベルがパネル部251の内側に引き込まれるのを抑制し、ラベルに外観不良が発生するのを抑制できる。
また、減圧時にパネル部251が径方向の内側に向けて変形した場合であっても、ラベルの変位は抑制される。その結果、所望の減圧吸収性能を維持した上で、胴部213に巻き付けられるラベルに外観不良が発生するのを抑制できる。
また、可動壁部222による減圧吸収機能が十分である場合、この可動壁部222を優先的に減圧変位させ、前記パネル部251の変形を抑制(防止)するように構成することもできる。
この場合は、例えば、リブ幅D1を可能な限り大きく形成することができ、より確実にラベルに外観不良が発生することを防止できる。
<サンプル21>リブ幅D1=6mm、パネル幅D2=26mm(D1/D2=23.1%)
<サンプル22>リブ幅D1=7mm、パネル幅D2=26mm(D1/D2=26.9%)
<サンプル23>リブ幅D1=8mm、パネル幅D2=26mm(D1/D2=30.8%)
<サンプル24>リブ幅D1=9mm、パネル幅D2=26mm(D1/D2=34.6%)
<サンプル25>リブ幅D1=10mm、パネル幅D2=26mm(D1/D2=38.5%)
<サンプル26>リブ幅D1=11mm、パネル幅D2=26mm(D1/D2=42.3%)
<サンプル27>リブ幅D1=12mm、パネル幅D2=26mm(D1/D2=46.2%)
特に、パネル幅D2に対するリブ幅D1の割合が38.5%より高い場合(サンプル26,27の場合)には、吸収容量が大幅に低下していることが分かる。これは、リブ幅D1が大きくなるにつれて、底壁部253の幅が縮小し、減圧時におけるパネル部251の変位量が低下するため、所望の減圧吸収性能を発揮できなかったためであると考えられる。この場合には、減圧強度の増加に追従できず、減圧途中でパネル部251以外の箇所に局部変形が生じる等の可能性がある。
これに対して、パネル幅D2に対するリブ幅D1の割合が38.5%以下の場合には、ラベルに外観不良が発生するのを抑制した上で、26(ml)以上の吸収容量を維持しており、十分な減圧吸収性能を発揮できた。
これに対して、パネル幅D2に対するリブ幅D1の割合が10%未満とした場合には、装着されたシュリンクラベルに外観の低下が見られた。
また、上述した実施形態では、肩部212、胴部213及び底部214のそれぞれの径方向に沿う横断面視形状を円形状としたが、これに限らず例えば、多角形状にする等適宜変更してもよい。
さらに、上述した実施形態では、リブ255が側壁部254との間に全周に亘って隙間をあけて配設した場合について説明した。しかし、これに限らず、リブ255は、少なくとも縦側壁部254aとの間に隙間をあけていれば構わない。
また、ボトル201を形成する合成樹脂材料は、例えばポリエチレンテレフタレートや、ポリエチレンナフタレート、非晶性ポリエステル等、またはこれらのブレンド材料等、適宜変更してもよい。
さらに、ボトル201は単層構造体に限らず中間層を有する積層構造体としてもよい。この中間層としては、例えばガスバリア性を有する樹脂材料からなる層、再生材からなる層、若しくは酸素吸収性を有する樹脂材料からなる層等が挙げられる。
