Description
本発明は、くびれ付きボトルに係り、特に、液体の体積減少による減圧を吸収するパネルを備えたくびれ付きボトルに関する。 The present invention relates to a bottle with a constriction, and more particularly, to a bottle with a constriction provided with a panel that absorbs reduced pressure due to a decrease in volume of liquid.
従来から、飲料などを収容するボトルとしては、様々な形状のものが提案されている。例えば、ボトルの上下方向の中間領域の直径を小さくした、いわゆるくびれ付きのボトルがある。くびれ付きのボトルは、見た目が美しいだけではなく、使用者がボトルのくびれた部分を把持した場合に、ボトルを確実に保持できるという特徴を有している。 Conventionally, bottles of various shapes have been proposed as bottles for containing beverages and the like. For example, there is a bottle with a so-called constriction in which the diameter of the middle region in the vertical direction of the bottle is reduced. A bottle with a constriction is not only beautiful in appearance, but also has a feature that the bottle can be securely held when the user grips the constricted portion of the bottle.
飲料などの樹脂製容器は、飲料が収容された後に冷却などの温度変化が加わるが、その際に内部の液体の体積減少などによって内部が減圧状態となり、容器が変形してしまう場合がある。これを防ぐために、ボトルの表面に減圧吸収用のパネルを設ける場合がある。このパネルは、一般的にボトルの表面から内部に向かって凹んだ構造のボトル壁である。パネルの形状としては様々なものが用いられているが、一般的には多角形を組み合わせた構造などが多く用いられている。またパネルは、減圧吸収を目的とするばかりではなく、使用する材料の量を低減しながら、ボトル自体の強度も向上させることができるので、容器にとっては重要なものである。この例としては、三角形のパネルを組み合わせたものが開示されている(特許文献1参照。)。 In a resin container such as a beverage, a temperature change such as cooling is applied after the beverage is accommodated, and at that time, the inside may be in a reduced pressure state due to a decrease in the volume of the liquid inside, and the container may be deformed. In order to prevent this, a panel for absorbing vacuum may be provided on the surface of the bottle. This panel is a bottle wall that is generally recessed from the surface of the bottle toward the inside. Various panel shapes are used, but generally, a structure in which polygons are combined is often used. The panel is not only intended for vacuum absorption, but is also important for the container because it can improve the strength of the bottle itself while reducing the amount of material used. As this example, a combination of triangular panels is disclosed (see Patent Document 1).
また、ボトル側面にパネルを設ける例としては、ボトルの側面において上下方向に延びる矩形状のパネルを設けることが開示されている。(特許文献2参照。)。この例では、ボトルの周囲に設けられたラベル表面に印刷された文字等を見易くするため、或いはラベル表面に印刷された絵柄等のデザインのイメージを変化させないようにするために、ボトル胴部のパネルの数を多くして多角形状としている。 Further, as an example of providing a panel on the side surface of the bottle, it is disclosed to provide a rectangular panel extending in the vertical direction on the side surface of the bottle. (See Patent Document 2). In this example, in order to make it easy to see the characters printed on the label surface provided around the bottle or to prevent the design image such as a pattern printed on the label surface from being changed, The number of panels is increased to create a polygonal shape.
また、ボトル側面にパネルを設ける他の例としては、変形した長方形のようなパネルをボトルの側面に設けると共に、ボトルの上下方向の中間付近に横リブを設けることが開示されている(特許文献3参照。)。この例では、横リブによる剛性向上効果と、各パネル間に形成される柱部により、容器の変形を押さえることができるとされている。 Further, as another example of providing a panel on the side surface of the bottle, it is disclosed that a panel such as a deformed rectangle is provided on the side surface of the bottle and a lateral rib is provided near the middle in the vertical direction of the bottle (Patent Document). 3). In this example, it is said that the deformation of the container can be suppressed by the rigidity improving effect by the lateral ribs and the pillar portions formed between the panels.
更に、ボトルの外観を滑らかな曲面に保持するために、表面にパネルを設けることなく剛性を保つために、山部と谷部が周方向に交互に配列される段差を設けたボトルが開示されている(特許文献4参照)。 Furthermore, in order to keep the appearance of the bottle in a smooth curved surface, a bottle provided with steps in which peaks and valleys are alternately arranged in the circumferential direction is disclosed in order to maintain rigidity without providing a panel on the surface. (See Patent Document 4).
しかしながら、上記のようなくびれ付きボトルでは、以下のような問題があった。すなわち、くびれ付きボトルの表面は緩やかに湾曲しているが、このような曲面で形成されているボトルの表面に多角形を組み合わせたパネルを形成すると、減圧による容器の変形が局所的に集中してしまい、ボトルに大きな変形をもたらしてしまう場合がある。また、くびれ部を有するボトルをポリエチレンテレフタレート(PET)などの材料で製造する場合、製造方法に起因してくびれ部の材料の肉厚が薄くなってしまう場合がある。 However, the bottle with the neck as described above has the following problems. In other words, the surface of a bottle with a constriction is gently curved, but if a panel that combines polygons is formed on the surface of a bottle that is formed with such a curved surface, deformation of the container due to decompression is concentrated locally. And may cause large deformation of the bottle. Moreover, when manufacturing the bottle which has a constriction part with materials, such as a polyethylene terephthalate (PET), the thickness of the material of a constriction part resulting from a manufacturing method may become thin.
また、連続的で滑らかな曲面で形成される側面を有するくびれ付きボトルに、引用文献1で開示したような、複数の多角形を組み合わせたパネルを適用すると、ボトル自体の美観を損ねると共に、ボトルを持った者が曲面と多角形との不整合に違和感を覚えることも考えられる。 In addition, when a panel combining a plurality of polygons as disclosed in the cited document 1 is applied to a bottle with a constriction having a side surface formed with a continuous and smooth curved surface, the aesthetic appearance of the bottle itself is impaired, and the bottle It is also possible that those who have a feeling of discomfort in the mismatch between the curved surface and the polygon.
また、引用文献2に開示されるようなボトルでは、単に壜体胴部の面数を増やしただけでは壜体内部の減圧吸収機能を有する面の面積が小さくなり、十分な機能が得られない。そのため、不規則な減圧変形がおきたり、胴部に配置された強度補強を目的として設けた凹状又は凸状リブの幅を狭くすることにより剛性低下をひき起こしてしまう。 Further, in the bottle as disclosed in the cited document 2, the area of the surface having the reduced pressure absorption function inside the housing is reduced simply by increasing the number of surfaces of the housing body, and a sufficient function cannot be obtained. . For this reason, irregular decompression deformation occurs, and a reduction in rigidity is caused by narrowing the width of the concave or convex rib provided for the purpose of reinforcing the strength disposed in the body.
また、引用文献3に開示されるようなボトルでは、減圧吸収パネル周囲の強度補強のために設けられる、周方向に連続した環状溝部は、胴部に対する横方向の外力や減圧吸収パネルの周囲の変形の防止には効果があるものの、壜体の高さ方向の負荷である垂直荷重強度に対しては逆効果であり、しばしば強度の低下をもたらしてしまう。 Further, in the bottle as disclosed in the cited document 3, the circumferentially continuous annular groove provided for reinforcing the strength around the decompression absorption panel is a lateral external force with respect to the trunk portion or the circumference of the decompression absorption panel. Although effective in preventing deformation, it is counterproductive to the vertical load strength, which is the load in the height direction of the housing, and often results in a decrease in strength.
更に、引用文献4に開示されるようなボトルでは、単純な山部と谷部からなる段差を用いて剛性を確保しているため、背の高いボトルに対しては適用できない。 Furthermore, the bottle as disclosed in the cited document 4 is not applicable to a tall bottle because rigidity is ensured by using a step formed by a simple peak and valley.
本発明は、上記問題点を解消できるくびれ付きボトルを提供することを目的とする。この目的を達成するために、本発明は、ボトルの側面の少なくとも一部に曲面で形成されたくびれ部を有するくびれ付きボトルであって、少なくとも前記くびれ部には少なくとも1枚の減圧吸収用のパネルが設けられ、前記パネルの幅はそのパネルの一端から他端にわたって連続的に変化する、という構成を採っている。 An object of this invention is to provide the bottle with a constriction which can eliminate the said problem. In order to achieve this object, the present invention provides a bottle with a constriction having a constricted portion formed in a curved surface on at least a part of a side surface of the bottle, wherein at least one constricted portion is used for absorbing vacuum. A panel is provided, and the width of the panel continuously changes from one end to the other end of the panel.
また、前記パネルは、前記くびれ部のうちの最もくびれた部分の幅が他の部分の幅よりも広い、という構成を採っている。
また、前記パネルの水平方向断面は、前記くびれ付きボトルの側面の他の部分よりもボトルの内部に向かって凹んでいる、という構成を採っている。
また、前記パネルの水平方向断面は、曲線となっている、という構成を採っている。
Moreover, the said panel has taken the structure that the width | variety of the narrowest part of the said narrow part is wider than the width | variety of another part.
Moreover, the horizontal direction cross section of the said panel has taken the structure that it is dented toward the inside of a bottle rather than the other part of the side surface of the said bottle with a constriction.
Moreover, the horizontal direction cross section of the said panel has taken the structure that it is a curve.
また、前記パネルは、前記くびれ付きボトルの上下両端近傍まで延設されている、という構成を採っている。
また、前記パネルは少なくとも2枚設けられ、当該パネルは前記くびれ付きボトルの周方向に沿って等間隔で配置されている、という構成を採っている。
更に、前記パネルの数は8枚である、という構成を採っている。
Moreover, the said panel is taken as the structure extended to the upper-and-lower-ends vicinity of the said bottle with a constriction.
Further, at least two panels are provided, and the panels are arranged at equal intervals along the circumferential direction of the constricted bottle.
Further, the number of the panels is eight.
本発明によれば、ボトルの側面の少なくとも一部に曲面で形成されたくびれ部を有するくびれ付きボトルにおいて、ボトル自体の強度を確保しながら且つ減圧吸収能力の高いボトルを実現することができる。また、くびれ部の材料の肉厚の減少を抑制することができる。加えて、ボトルの美観を美しく保ちながら、ボトルを持った者が違和感を覚えないボトルを実現することができる。 ADVANTAGE OF THE INVENTION According to this invention, the bottle with a constriction which has the constriction part formed in the curved surface in at least one part of the side surface of the bottle can implement | achieve a bottle with high decompression absorption capability, ensuring the intensity | strength of bottle itself.

次に、本願発明の一実施形態について図面を参照しながら説明する。
[全体概要]
本発明の一実施形態に係るくびれ付きボトル1は、ボトルの側面の少なくとも一部であって、ボトルの上下方向の中間部分に曲面で形成されたくびれ部11を有するひょうたん型であり、本実施形態では上下方向の中心よりもやや上方に寄った位置にくびれ部11が形成されている。くびれ付きボトル1の側面は、概ね円形断面を形成する側壁21と、少なくともくびれ部に形成された減圧吸収用のパネル31とからなる。また、くびれ付きボトル1の上端にはキャップ(図示略)を係合するためのキャップ係合部41が形成されている。尚、本実施形態のくびれ付きボトル1は、透明のポリエチレンテレフタレート材料からなる、いわゆるPETボトルである。
Next, an embodiment of the present invention will be described with reference to the drawings.
[Overview]
A bottle with a constriction 1 according to an embodiment of the present invention is a gourd type having a constricted portion 11 formed at a middle portion in the vertical direction of the bottle at least a part of a side surface of the bottle and formed into a curved surface. In the form, the constricted portion 11 is formed at a position slightly above the center in the vertical direction. The side surface of the bottle 1 with a constriction is composed of a side wall 21 having a substantially circular cross section and a panel 31 for absorbing vacuum at least at the constricted portion. Moreover, the cap engaging part 41 for engaging with a cap (not shown) is formed in the upper end of the bottle 1 with a constriction. Note that the constricted bottle 1 of the present embodiment is a so-called PET bottle made of a transparent polyethylene terephthalate material.
[側壁]
側壁21は、くびれ付きボトル1の上端部から下端部まで連続する壁部材であり、水平方向の断面で見た場合に、図2に示すように、パネル31の部分を除いて概ね円形断面を有している。各部の円形断面の直径は、くびれ部11が最小で、くびれ付きボトル1の上部が中間の大きさで、下部が最大となっている。上下方向の中間部分がくびれ部11となっているので、このくびれ部11を把持することにより、くびれ付きボトル1を確実に保持することができる。尚、ここで「くびれ部」という場合、最小直径の部分を含み、更にその上下近傍領域も含むものとする。このため、本発明は、例えばくびれ部のみが曲面で形成され、その他の部分が平面の組み合わせからなるようなボトルに対しても適用できると理解されるべきである。
[Sidewall]
The side wall 21 is a wall member continuous from the upper end portion to the lower end portion of the bottle 1 with a constriction. When viewed in a horizontal cross section, the side wall 21 has a substantially circular cross section except for the panel 31 as shown in FIG. Have. The diameter of the circular cross section of each part is such that the constricted part 11 is the smallest, the upper part of the constricted bottle 1 is an intermediate size, and the lower part is the largest. Since the middle part of the up-and-down direction becomes the constriction part 11, the bottle 1 with a constriction can be reliably hold | maintained by hold | gripping this constriction part 11. FIG. Here, the “neck portion” includes a portion having a minimum diameter and further includes a region in the vicinity of the upper and lower sides. For this reason, it should be understood that the present invention can be applied to a bottle in which, for example, only the constricted portion is formed with a curved surface and the other portions are formed of a combination of planes.
[パネル]
また、くびれ付きボトル1の側面には複数のパネル31が形成されている。このパネル31はくびれ部11のうち最もくびれた(直径の小さな)部分の幅が最も広く、一端と他端(立てられたボトルの場合は上下方向の両端部近傍)の幅が最も狭い、いわゆる舟形状のパネルになっており、幅は連続的に変化している。パネル31の断面形状は、図2(C)及び図3に示すように、内側に向かって曲面状に凹むような形状となっている。また、パネル31の深さは、くびれ部11が最も深く(約3mm)、上下方向の両端部が最も浅くなるように構成されている。尚、図3はくびれ付きボトルの斜視図であり、ボトルの表面に図示されている各線は立体形状の理解を助けるためのものである。本実施形態におけるパネル31は、くびれ付きボトル1の上下両端近傍まで延設されている。しかし、本発明はこれに限定されるものではなく、くびれ部11にのみパネル31を形成するようにしても良いし、くびれ部11を超えて、ボトルの上下両端近傍までは届かない程度の長さに設定してもよい。
[panel]
Moreover, the some panel 31 is formed in the side surface of the bottle 1 with a constriction. This panel 31 has the narrowest (smallest diameter) portion of the constricted portion 11 having the widest width, and the narrowest width at one end and the other end (near the both vertical ends in the case of a standing bottle). It is a boat-shaped panel, and the width changes continuously. As shown in FIGS. 2C and 3, the cross-sectional shape of the panel 31 is a shape that is recessed in a curved shape toward the inside. Further, the depth of the panel 31 is configured such that the constricted portion 11 is the deepest (about 3 mm) and the both ends in the vertical direction are the shallowest. FIG. 3 is a perspective view of a bottle with a constriction, and each line shown on the surface of the bottle is for helping understanding of the three-dimensional shape. The panel 31 in this embodiment is extended to the vicinity of the upper and lower ends of the bottle 1 with a constriction. However, the present invention is not limited to this, and the panel 31 may be formed only in the constricted portion 11, and the length is such that it does not reach the vicinity of both upper and lower ends of the bottle beyond the constricted portion 11. You may set it.
本実施形態に係るくびれ付きボトル1において、パネル31の数は8枚である。これは、ボトル自体の強度を確保しながら、減圧によるボトルの変形を確実に吸収できるようにするためである。しかしながら、本発明はこれに限定されるものではなく、1枚から7枚或いは9枚以上であってもよい。但し、パネル31の枚数に応じて、それぞれのパネル31の幅も調整する必要がある。尚、本実施形態に係るくびれ付きボトル1は上記した500ml用であり、具体的な寸法の一例を説明すると、その高さは約220mmであり、くびれ部11の最小直径部の高さは下端から約125mmの位置である。また、パネルの最大幅はくびれ部11の最小直径部近傍に存在しており、その幅は約15.8mmである。また、図1におけるA−A線で示すくびれ部の最小直径が約53.5mm、B−B線で示す上部の直径が約63mm、そしてC−C線で示す下部の直径が約68.5mmとなっている。 In the bottle 1 with a constriction according to the present embodiment, the number of the panels 31 is eight. This is to ensure that the deformation of the bottle due to the reduced pressure can be absorbed while securing the strength of the bottle itself. However, the present invention is not limited to this, and may be 1 to 7 sheets or 9 sheets or more. However, it is necessary to adjust the width of each panel 31 according to the number of panels 31. In addition, the bottle 1 with a constriction which concerns on this embodiment is for 500 ml mentioned above, and when an example of a specific dimension is demonstrated, the height is about 220 mm and the height of the minimum diameter part of the constriction part 11 is a lower end. It is a position of about 125 mm from. The maximum width of the panel is present in the vicinity of the minimum diameter portion of the constricted portion 11, and the width is about 15.8 mm. Further, the minimum diameter of the constricted portion shown by the AA line in FIG. 1 is about 53.5 mm, the upper diameter shown by the BB line is about 63 mm, and the lower diameter shown by the CC line is about 68.5 mm. It has become.
[キャップ係合部]
くびれ付きボトル1の上端はキャップ係合部41となっている。このキャップ係合部41には雄ねじ部41aが形成されており、キャップ(図示略)の内面に形成された雌ネジ部と係合するようになっている。但し、当該雄ねじ部41aは本発明に必須なものではなく、例えば単純な円筒部に形成してキャップを押込んで封止するような構造にしてもよい。
[Cap engaging part]
The upper end of the bottle 1 with a constriction is a cap engaging portion 41. The cap engaging portion 41 is formed with a male screw portion 41a and is engaged with a female screw portion formed on the inner surface of a cap (not shown). However, the male screw portion 41a is not essential to the present invention, and may be formed, for example, in a simple cylindrical portion and sealed by pushing the cap.
[ボトル各部の肉厚]
本発明に係るくびれ付きボトル1は、例えばブロー成形と呼ばれる方法で成型される。これは、ボトルの形状を決める型の中にプリフォームを保持し、内側へ圧縮空気を導入することによって材料を型に押し付けるものである。このような手法に起因して、くびれ付きボトル1の成形においては、くびれ部の肉厚が薄くなってしまう場合がある。例えば、パネルが形成されていない、平滑な側面を有するくびれ付きボトルの場合、図4に示すように、くびれ部以外の肉厚は0.35mmから0.37mm程度あるが、くびれ部の肉厚は0.29mm程度に減少してしまう。
[Thickness of each part of the bottle]
The constricted bottle 1 according to the present invention is molded by a method called blow molding, for example. This holds the preform in a mold that determines the shape of the bottle and presses the material against the mold by introducing compressed air inside. Due to such a method, in the formation of the bottle 1 with a constriction, the thickness of the constricted portion may become thin. For example, in the case of a bottle with a constriction having a smooth side surface without a panel, as shown in FIG. 4, the thickness other than the constriction is about 0.35 mm to 0.37 mm. Decreases to about 0.29 mm.
一方、図5はパネル31を有するくびれ付きボトル1の各部の肉厚を示す表である。この表に示すように、くびれ部11の最小直径部の肉厚が0.34mmとなっており、その上下領域の肉厚(0.27〜0.29mm)よりも厚くなっている。これは、パネル31を形成するための成型用型に凹凸が形成され、この凹凸による肉止め効果によるものである。このように、適切なパネルを形成することで、結果としてパネルを有しないボトルと比較してくびれ部11の肉厚が増大すると共に、くびれ付きボトル1の高さ方向にあたかも柱が形成されたような効果が生じるので、くびれ部11の縦圧縮強度を増大させることができる。 On the other hand, FIG. 5 is a table showing the thickness of each part of the constricted bottle 1 having the panel 31. As shown in this table, the thickness of the minimum diameter portion of the constricted portion 11 is 0.34 mm, which is thicker than the thickness ( 0.27 to 0.29 mm) of the upper and lower regions. This is because irregularities are formed in the mold for forming the panel 31 and the meat stop effect due to the irregularities. Thus, by forming an appropriate panel, as a result, the thickness of the constricted portion 11 is increased as compared with a bottle having no panel, and a column is formed in the height direction of the constricted bottle 1. Since such an effect arises, the longitudinal compression strength of the constricted part 11 can be increased.
[内容物の充填方法]
当該くびれ付きボトル1には、一例として飲料が充填される。飲料はその種類に応じて充填方法が異なるので、それらを簡単に説明する。具体的には、1)ホットパック、2)常温無菌充填、3)コールド充填、の3種類が一般的である。
[Content filling method]
The bottle 1 with a constriction is filled with a drink as an example. Since beverages have different filling methods depending on their types, they will be described briefly. Specifically, three types of 1) hot pack, 2) normal temperature aseptic filling, and 3) cold filling are common.
ホットパックとは、常温よりもかなり高い温度(例えば、85℃)でボトルに充填する方法である。この方法が用いられるのは、スポーツドリンク、果汁飲料などである。また、常温無菌充填とは、25℃程度の温度で飲料をボトルに充填する方法である。この方法が用いられるのは、お茶、水、ミルク入りコーヒー、紅茶などである。更に、コールド充填とは、常温よりも低い温度で充填する方法であり、炭酸飲料などの充填に用いられる。ここで、本発明は、上記した各充填方法のうち、1)ホットパックと2)常温無菌充填に対して適用することができる。 The hot pack is a method of filling a bottle at a temperature considerably higher than normal temperature (for example, 85 ° C.). This method is used for sports drinks, fruit juice drinks, and the like. Moreover, normal temperature aseptic filling is a method of filling a bottle with a beverage at a temperature of about 25 ° C. This method is used for tea, water, coffee with milk, tea and the like. Furthermore, cold filling is a method of filling at a temperature lower than normal temperature, and is used for filling carbonated beverages and the like. Here, the present invention can be applied to 1) hot pack and 2) room temperature aseptic filling among the above-described filling methods.
[減圧の発生]
ボトルに飲料を充填した後には、以下のような様々な原因によって、ボトル内が減圧状態となる。例えば、上記した常温無菌充填の場合、飲料は25℃程度の温度の状態でボトルに充填されるが、実際の販売状態では5℃程度に冷却されて店頭に並ぶこととなる。このような温度変化によって液体である飲料は収縮する。その収縮量は、例えば500mlのボトルの場合、3.7ml程度となる。これによって、ボトル内部が減圧状態となる。また、飲料の充填後でもボトルの最上部には一定量の気体が残留している。この気体内には酸素も含まれており、冷却によって飲料内に酸素が溶け込むことによって2ml程度の量に相当する減圧が発生する。更に、飲料が充填されたPETボトルなどの場合、在庫期間中の時間の経過と共に水分がボトルを透過してしまう。その量は全容量に対して毎月0.1%程度となる。従って、500mlのボトルの場合、0.5ml/月程度の水分が失われる。この状態で、例えば8ヶ月間保管されるとすると、最大4ml程度の水分がボトルを透過することとなる。
[Generation of decompression]
After filling the bottle with the beverage, the inside of the bottle is in a reduced pressure state due to various causes as follows. For example, in the case of the above-described normal temperature aseptic filling, the beverage is filled in the bottle at a temperature of about 25 ° C., but in an actual sales state, it is cooled to about 5 ° C. and lined up at the store. The beverage which is a liquid shrinks by such a temperature change. The amount of shrinkage is, for example, about 3.7 ml in the case of a 500 ml bottle. Thereby, the inside of a bottle will be in a pressure reduction state. In addition, a certain amount of gas remains at the top of the bottle even after the beverage is filled. This gas contains oxygen, and when the oxygen is dissolved in the beverage by cooling, a reduced pressure corresponding to an amount of about 2 ml is generated. Furthermore, in the case of a PET bottle filled with a beverage, moisture permeates through the bottle with the passage of time during the inventory period. The amount is about 0.1% per month with respect to the total capacity. Therefore, in the case of a 500 ml bottle, about 0.5 ml / month of water is lost. In this state, for example, if stored for 8 months, a maximum of about 4 ml of water will permeate the bottle.
以上のようなそれぞれの減圧要因を足し合わせると、体積に換算して約10ml弱に相当する減圧が発生することとなる。このため、例えば500ml入りのボトルが変形せずに、当初からの形状を維持するためには、最低でも10ml程度の減圧吸収能力が求められる。減圧吸収用のパネルを有しないくびれ付きボトルでは、上記減圧によって容器が大きく変形してしまう。具体的には円形断面がつぶれて、楕円に近い断面形状ととなってしまう場合がある。このような変形が生じると、流通過程の製品価値が著しく低下してしまう。 When the respective decompression factors as described above are added, decompression corresponding to a little less than about 10 ml is generated in terms of volume. For this reason, for example, in order to maintain the original shape without deformation of a bottle containing 500 ml, a vacuum absorbing capacity of about 10 ml is required at least. In a bottle with a constriction that does not have a panel for absorbing reduced pressure, the container is greatly deformed by the reduced pressure. Specifically, the circular cross section may be crushed and become a cross sectional shape close to an ellipse. When such deformation occurs, the product value of the distribution process is significantly reduced.
[作用]
次に、上記減圧に対する本実施形態のくびれ付きボトル1の作用について説明すると、本発明では舟形状のパネル31を設けることで、大きな減圧吸収能力が得られる。具体的には、パネル31が減圧を吸収するようにくびれ付きボトル1の内部側に僅かに凹む。これによって飲料の体積の減少分を確実に吸収し、他の部分に変形の影響を与えない。特に、本実施形態のパネル31は、くびれ付きボトルの上下両端近傍まで延びており、パネル31のボトル内部方向への移動が比較的自由に行われる。このため、くびれ付きボトル1の全体形状は、内部の圧力状態に関係なく充填当初の形状を維持する。
[Action]
Next, a description will be given of the operation of the bottle 1 with a constriction of the present embodiment with respect to the above decompression. In the present invention, a large decompression absorption capacity is obtained by providing the boat-shaped panel 31. Specifically, the panel 31 is slightly recessed on the inner side of the constricted bottle 1 so as to absorb the reduced pressure. This reliably absorbs the reduced volume of the beverage and does not affect the other parts. In particular, the panel 31 of the present embodiment extends to the vicinity of the upper and lower ends of the bottle with a constriction, and the movement of the panel 31 toward the inside of the bottle is performed relatively freely. For this reason, the whole shape of the bottle 1 with a constriction maintains the original shape of filling irrespective of an internal pressure state.
また、本実施形態に係るくびれ付きボトル1では、パネル31が幅と深さに関して連続的に変化する滑らかな舟形状となっているため、減圧による応力が局所に集中することがない。加えて、パネル31がくびれ付きボトル1の上下方向の両端付近まで延設されていることから、このパネル31が柱のような機能を発揮し、くびれ付きボトル1に対する上下方向の圧縮力に対しても十分な強度を有することとなる。 Moreover, in the bottle 1 with a constriction which concerns on this embodiment, since the panel 31 becomes the smooth boat shape which changes continuously regarding width and depth, the stress by decompression does not concentrate locally. In addition, since the panel 31 extends to the vicinity of both ends in the vertical direction of the bottle 1 with constriction, the panel 31 performs a function like a column, and against the compressive force in the vertical direction with respect to the bottle 1 with constriction. However, it will have sufficient strength.
更に、滑らかなくびれ部11を有するくびれ付きボトル1に、くびれ部に対応して滑らかに幅や深さが変化する舟形状のパネル31を用いることにより、これを見る者に美観を覚えさせ、また、実際にくびれ付きボトル1を握った者にも違和感を覚えさせることがない、という特性を有している。 Furthermore, by using the boat-shaped panel 31 whose width and depth change smoothly corresponding to the constricted portion, the bottle 1 with the constricted portion 11 having the smooth constricted portion 11 is used to make the person who sees this memorize the beauty, Moreover, it has the characteristic that the person who actually squeezed the bottle 1 with the constriction will not feel uncomfortable.
尚、本実施形態では、くびれ付きボトル1の上下方向の中間領域にくびれ部11を1カ所有するくびれ付きボトル1に基づいて説明したが、本発明はこれに限定されるものではない。たとえば、くびれ部を2カ所設けたようなくびれ付きボトルに対しても適用することができる。また、本実施形態では、くびれ部11はくびれ付きボトル1の円周方向に沿って略水平に形成されているが、本発明はこれに限定されるものではなく、例えば長手方向に対して傾斜し、ボトルの側面にいわゆる螺旋状に形成するようにしてもよい。 In addition, although this embodiment demonstrated based on the bottle 1 with a constriction which owns one constriction part 11 in the intermediate area of the up-down direction of the bottle 1 with a constriction, this invention is not limited to this. For example, the present invention can also be applied to a bottle with a neck that has two constricted portions. In the present embodiment, the constricted portion 11 is formed substantially horizontally along the circumferential direction of the constricted bottle 1, but the present invention is not limited to this, and is inclined with respect to the longitudinal direction, for example. In addition, a so-called spiral shape may be formed on the side surface of the bottle.
本発明は、液体などを収容するボトル容器などの構造に利用可能である。 The present invention can be used for a structure of a bottle container or the like for storing a liquid or the like.
