Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of a bottle formed by biaxially stretching blow-molding a resin containing a polylactic acid, the problem being that when a dome-like expansion part is formed in the upper part of the bottle so as to have an oval cross-sectional shape and a waist continuous with the expansion part and narrowing inside is formed below the expansion part, stress concentrates on the waist, with result that the cross-sectional shape of the waist is deformed into a slanting oval shape from an original oval shape. <P>SOLUTION: The bottle 1 has a bottom 5 having a ground face F and formed by biaxially stretching blow-molding resin containing a polylactic acid. The bottle 1 has the oval cross-sectional shape, and the dome-shaped expansion part 3 in the upper part of the bottle 1. A waist part 4 is formed below the expansion part 3 so as to be continuous with the expansion part 3 and narrow inside. The waist part 4 is provided with an annular rib 7 extending around the bottle axis O. The rib 7 is disposed within the range of 5 mm above or below the narrowest part 4a of the waist along the axial line of the bottle. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、自然分解することで廃棄処理の容易なボトルに関するものである。   The present invention relates to a bottle that is easily decomposed by natural decomposition.

廃棄処理の容易なボトルとしては、ポリ乳酸を含む樹脂をブロー成形してなるものがある（例えば、特許文献１参照）。
特開２００２−２７４５２１号公報 As a bottle that can be easily discarded, there is a bottle formed by blow molding a resin containing polylactic acid (see, for example, Patent Document 1).
JP 2002-274521 A

しかしながら、こうした乳酸成分を含む樹脂は、比較的脆く、耐衝撃強度が低いことが知られている（例えば、特許文献２参照）。
特許第３８０９８５０号明細書 However, it is known that such a resin containing a lactic acid component is relatively brittle and has low impact strength (see, for example, Patent Document 2).
Japanese Patent No. 3809850

このため、ポリ乳酸を含む樹脂をブロー成形してなるボトルの横断面形状を楕円形状とし、当該ボトルの上部にドーム状などの膨出部を形成すると共に、この膨出部の下側に、当該膨出部に連なって内側にくびれたウエスト部を形成する場合、かかる形状のボトルは、積載時において上部から荷重が加わることにより、或いは、ラベラーを用いてウエスト部にラベルを装着することにより、当該ウエスト部（特に、ウエスト部の最深部）の横断面形状が、本来の楕円形状に対して斜め楕円形状に変形してしまうことがある。   For this reason, the cross-sectional shape of the bottle formed by blow molding a resin containing polylactic acid is an elliptical shape, and a bulge portion such as a dome shape is formed on the upper portion of the bottle, and below the bulge portion, When forming a waist part that is constricted on the inside in connection with the bulging part, the bottle with such a shape is loaded by applying a load from the top during loading, or by attaching a label to the waist part using a labeler. The cross-sectional shape of the waist part (particularly the deepest part of the waist part) may be deformed into an oblique elliptical shape with respect to the original elliptical shape.

これに対し、本願発明者は、ウエスト部の機械的強度（剛性）を高めるべく、当該ウエスト部に、リブを設けることで剛性を上げるに至ったが、ポリ乳酸を含むボトルは、上述の如く、ＰＥＴを含む樹脂よりも耐衝撃強度が低いため、割れ等を生じやすい。   In contrast, in order to increase the mechanical strength (rigidity) of the waist part, the inventor of the present application has increased the rigidity by providing ribs on the waist part. However, the bottle containing polylactic acid is as described above. Since the impact strength is lower than that of a resin containing PET, cracks and the like are likely to occur.

このため、例えば、当該リブを、ボトルの内側に向かって湾曲した凹部がボトルの軸線周りに周回する環状の凹部とした場合、この凹部の深さを深くしたり、当該凹部を形作るＲ（曲率半径）を小さくすることで、ウエスト部の機械的強度（剛性）を極端に高めると、割れ等を生じる可能性がある。このため、本願発明者は、リブの深さや曲率半径等で決定されるリブの形態を変更することで、ウエスト部の機械的強度を高めるには限界があることを認識するに至った。   For this reason, for example, when the rib is an annular recess in which a concave portion curved toward the inside of the bottle circulates around the axis of the bottle, the depth of the concave portion is increased or R (curvature) forming the concave portion is formed. If the mechanical strength (rigidity) of the waist part is extremely increased by reducing the radius, cracking or the like may occur. For this reason, this inventor came to recognize that there exists a limit in improving the mechanical strength of a waist part by changing the form of the rib determined by the depth of a rib, a curvature radius, etc.

本発明の解決すべき課題は、ポリ乳酸を含む樹脂を二軸延伸ブロー成形してなるボトルにおいて、その横断面形状を楕円形状とし、当該ボトルの上部に膨出部を形成すると共に、この膨出部の下側に、当該膨出部に連なって内側にくびれたウエスト部を形成したとき、
このウエスト部に応力が集中すると、当該ウエスト部の横断面形状が、本来の楕円形状に対して斜め楕円形状に変形してしまうことにある。 The problem to be solved by the present invention is that, in a bottle formed by biaxial stretching blow molding of a resin containing polylactic acid, the cross-sectional shape thereof is elliptical, and a bulging portion is formed at the top of the bottle, and When forming a waist part that is constricted inward on the lower side of the protruding part, connected to the bulging part,
When stress concentrates on the waist portion, the cross-sectional shape of the waist portion is deformed into an oblique elliptical shape with respect to the original elliptical shape.

本発明は、接地面を有する底部を有し、ポリ乳酸を含む樹脂を二軸延伸ブロー成形してなるボトルであって、
当該ボトルは、その横断面形状が楕円形状をしてなり、当該ボトルの上部に膨出部を有し、この膨出部の下側に、当該膨出部に連なって内側にくびれたウエスト部を形成すると共に、
当該ウエスト部の最深部を含む所定位置に、ボトルの軸線周りを周回する環状のリブを備えることを特徴とするものである。なお、上記膨出部は、ドーム状であることが好ましい。 The present invention has a bottom portion having a ground contact surface, and is a bottle formed by biaxially stretch blow molding a resin containing polylactic acid,
The bottle has an elliptical cross-sectional shape, and has a bulging portion at the top of the bottle, and a waist portion that is constricted inward from the bulging portion below the bulging portion. And forming
An annular rib that circulates around the axis of the bottle is provided at a predetermined position including the deepest portion of the waist portion. In addition, it is preferable that the said bulging part is dome shape.

本発明によれば、ウエスト部の最深部を含む前記所定位置を、ボトルの軸線に沿って上下方向に延在する範囲のうち、ウエスト部の最深部を基点に、上８ｍｍ〜下５ｍｍの範囲とし、当該範囲内に、かかるリブを配置することが好ましいが、より好ましくは、最深部を基点に上下５ｍｍの範囲内に配置することである。本発明では特に、最深部を基点に、ボトルの軸線に沿って上側に向かって２mmの位置を上限値とする一方、下側に向かって１mm以下の位置を下限値とすることがさらに好ましいが、最も好ましいのは、最深部に配置することである。   According to the present invention, the predetermined position including the deepest part of the waist part extends in the vertical direction along the axis of the bottle, and ranges from 8 mm above to 5 mm below from the deepest part of the waist part. In this range, it is preferable to dispose such a rib, but it is more preferable to dispose the rib within a range of 5 mm above and below the deepest part. In the present invention, in particular, it is more preferable that the upper limit is a position of 2 mm toward the upper side along the axis of the bottle from the deepest point, while the lower limit is a position of 1 mm or less toward the lower side. Most preferably, it is arranged at the deepest part.

上記リブは、ボトルの内側に向かって湾曲した凹部をボトルの軸線周りに周回させた環状の凹部であって、この凹部の端部がそれぞれ、当該凹部を除くウエスト部に連なる曲面であるものが挙げられる。また、ボトルは、少なくともポリ乳酸を含む樹脂であればよい。   The rib is an annular concave portion in which a concave portion curved toward the inside of the bottle is made to circulate around the axis of the bottle, and each end portion of the concave portion is a curved surface continuous to the waist portion excluding the concave portion. Can be mentioned. The bottle may be a resin containing at least polylactic acid.

さらに、本発明は、調味料を充填した調味料充填ボトルとして適用することができ、特に調味料としては、食用油が好ましい。   Furthermore, the present invention can be applied as a seasoning-filled bottle filled with a seasoning, and edible oil is particularly preferable as the seasoning.

なお、本発明は、ポリ乳酸を含む樹脂を二軸延伸ブロー成形してなるボトルであるが、使用する樹脂としては自然分解の点から考えるに、ポリ乳酸を単体で１００質量％とするか、又は、他の生分解性樹脂とのブレンドした樹脂を使用するのが好ましい。   In addition, the present invention is a bottle formed by biaxial stretching blow molding a resin containing polylactic acid, but as a resin to be used from the viewpoint of natural degradation, polylactic acid alone is 100% by mass, Alternatively, it is preferable to use a resin blended with another biodegradable resin.

本発明では、ポリ乳酸を含む樹脂を二軸延伸ブロー成形してなるボトルにおいて、その横断面形状を楕円形状とし、当該ボトルの上部に膨出部を形成すると共に、この膨出部の下側に、当該膨出部に連なって内側にくびれたウエスト部を形成し、
更に、このウエスト部に、ボトルの軸線周りを周回する環状のリブを設けたことから、当該ウエスト部に応力が集中したときも、その形状がリブによって幾何学的に変化しているため、当該ウエスト部の機械的強度を高めることができる。従って、ウエスト部に応力が集中することによって、その横断面形状が、本来の楕円形状に対して斜め楕円形状に変形するような現象の発生を抑制することができる。 In the present invention, in a bottle formed by biaxial stretching blow molding of a resin containing polylactic acid, the cross-sectional shape is an elliptical shape, and a bulge is formed at the top of the bottle, and the lower side of the bulge And forming a waist portion constricted inward from the bulging portion,
Furthermore, since an annular rib that circulates around the axis of the bottle is provided at the waist, even when stress is concentrated on the waist, the shape is geometrically changed by the rib. The mechanical strength of the waist can be increased. Therefore, when stress concentrates on the waist, it is possible to suppress the occurrence of a phenomenon in which the cross-sectional shape is deformed into an oblique elliptical shape with respect to the original elliptical shape.

加えて、本発明によれば、当該リブを、ボトルの軸線に沿って上下方向に延在する範囲のうち、ウエスト部の最深部を基点に、上８ｍｍ〜下５ｍｍの範囲内に配置したことで、かかるリブの形状的な変化によって機械的強度を高めるのとは別に、当該リブの配置によっても、変形の起こり易いウエスト部の最深部付近の機械的強度を高めることができる。   In addition, according to the present invention, the rib is disposed within the range of 8 mm above to 5 mm below from the deepest part of the waist part in the range extending vertically along the axis of the bottle. Thus, apart from increasing the mechanical strength by changing the shape of the rib, the mechanical strength in the vicinity of the deepest portion of the waist portion where deformation easily occurs can also be achieved by the arrangement of the rib.

従って、本発明によれば、ウエスト部に割れ等を生じさせることなく、機械的強度を高めるためのリブを設けることができ、これにより、当該ウエスト部の機械的強度を効果的に高めることから、ウエスト部に発生する変形を効果的に防止することができる。   Therefore, according to the present invention, it is possible to provide a rib for increasing the mechanical strength without causing a crack or the like in the waist portion, thereby effectively increasing the mechanical strength of the waist portion. The deformation | transformation which generate | occur | produces in a waist part can be prevented effectively.

特に、上記リブを、ウエスト部の一部をボトルの内側に向かって湾曲させたボトルの軸線周りを周回してなる環状の凹部とすると共に、当該リブの端部をそれぞれ、かかるリブを除くウエスト部に向かって連なる曲面とすれば、リブに対する過度な応力集中を緩和することができる。   In particular, the rib is an annular recess formed by circling around the axis of the bottle with a part of the waist curved toward the inside of the bottle, and each end of the rib is a waist excluding the rib. If the curved surface is continuous toward the part, excessive stress concentration on the rib can be reduced.

以下、図面を参照して、本発明である、ボトルの一形態を詳細に説明する。   Hereinafter, an embodiment of a bottle according to the present invention will be described in detail with reference to the drawings.

図１(a),(b)はそれぞれ、本発明の一形態であるボトル１を示す正面図及びその側面図である。また、図２(a)〜(c)はそれぞれ、図１(a)のＡ−Ａ断面図、Ｂ−Ｂ断面図及び底面図である。更に、図３(a),(b)はそれぞれ、ボトル１に設けたリブ２を拡大して示す要部断面図及び、そのウエスト部での変形状態を示す横断面図である。   1A and 1B are a front view and a side view showing a bottle 1 which is an embodiment of the present invention. FIGS. 2A to 2C are an AA sectional view, a BB sectional view, and a bottom view of FIG. 1A, respectively. 3 (a) and 3 (b) are an enlarged cross-sectional view of the main part showing the rib 2 provided on the bottle 1, and a transverse cross-sectional view showing a deformed state at the waist part.

ボトル１は、環境中の水分で加水分解されることにより低分子化され、更に、微生物等の働きによって、最終的に二酸化炭素と水とに分解されるポリ乳酸を含む樹脂からなる図示せぬプリフォームを用い、当該プリフォームを二軸延伸ブロー成形することで形成されている。   The bottle 1 is made of a resin containing polylactic acid that is reduced in molecular weight by being hydrolyzed with moisture in the environment and that is finally decomposed into carbon dioxide and water by the action of microorganisms or the like (not shown). The preform is formed by biaxial stretch blow molding of the preform.

また、ボトル１は、その横断面形状が楕円形状をなし、図１，２に示すように、口部２を上端部として、この口部２の下側にドーム状の膨出部３を有する。膨出部３は、同各図に示すように、口部２の下側から外向きに拡径することで構成される、お碗を被せた形状をしてなる。   Further, the bottle 1 has an elliptical cross-sectional shape, and has a mouth portion 2 as an upper end portion and a dome-shaped bulging portion 3 below the mouth portion 2 as shown in FIGS. . As shown in the drawings, the bulging portion 3 has a shape covered with a bowl, which is formed by expanding the diameter outward from the lower side of the mouth portion 2.

膨出部３は、その横断面形状が楕円形状をなし、図１(a),(b)を比較すれば明らかなように、正面から見たときの外観形状が側面から見たときの外観形状に比べて幅広の形状となる。また、膨出部３は、図１(a)に示すＡ−Ａ断面部分にて最大径となる。この最大径部分（以下、「最大膨出部３ａ」という）は、図２(a)に示すように、その短径Ａa(x)が正面に対して垂直に延在すると共に、その長径Ａa(y)が側面に対して垂直に延在する。   The bulging portion 3 has an elliptical cross-sectional shape, and as seen from a comparison of FIGS. 1 (a) and 1 (b), the appearance when viewed from the front is the appearance when viewed from the side. The shape is wider than the shape. Moreover, the bulging part 3 becomes the largest diameter in the AA cross-section part shown to Fig.1 (a). As shown in FIG. 2 (a), the maximum diameter portion (hereinafter referred to as “maximum bulging portion 3a”) has a short diameter Aa (x) extending perpendicularly to the front surface and a long diameter Aa. (y) extends perpendicular to the side.

加えて、ボトル１は、図１，２に示すように、最大膨出部３ａに連なってボトル１の内側にくびれたウエスト部４を有する。ウエスト部４は、同各図に示すように、最大膨出部３ａから内向きに縮径することでＢ−Ｂ断面部分にて最小径となる最小径部分（以下、「ウエスト最深部４ａ」という）を有し、このウエスト最深部４ａに達したのち、当該ウエスト最深部４ａから外向きに拡径することで構成される絞り形をしてなる。   In addition, as shown in FIGS. 1 and 2, the bottle 1 has a waist portion 4 that is connected to the maximum bulging portion 3 a and is constricted inside the bottle 1. As shown in the drawings, the waist portion 4 has a minimum diameter portion (hereinafter referred to as “waist deepest portion 4a”) that becomes the minimum diameter in the BB cross-section portion by reducing the diameter inward from the maximum bulge portion 3a. And after reaching the waist deepest part 4a, it is formed into a drawing shape that is formed by expanding outward from the waist deepest part 4a.

なお、ウエスト最深部４ａからの拡径は、Ｃ−Ｃ断面部分にて最大径となり、この最大径部分（以下、「胴裾部４ｂ」という）には、底部５が連なる。   In addition, the diameter expansion from the waist deepest part 4a becomes a maximum diameter in CC cross-section part, and the bottom part 5 continues in this maximum diameter part (henceforth "the trunk | drum skirt part 4b").

ウエスト部４も、その横断面形状が楕円形状をなし、図１(a),(b)を比較すれば明らかなように、正面から見たときの外観形状が側面から見たときの外観形状に比べて幅広の形状となる。また、ウエスト最深部４ａは、図２(b)に示すように、その短径Ａb(x)が正面に対して垂直に延在すると共に、その長径Ａa(y)が側面に対して垂直に延在する。   The waist 4 also has an elliptical cross-sectional shape, and as is apparent from a comparison of FIGS. 1 (a) and 1 (b), the appearance when viewed from the front is the appearance when viewed from the side. Compared to the shape of the wide. Further, as shown in FIG. 2B, the deepest waist portion 4a has a short diameter Ab (x) extending perpendicular to the front surface and a long diameter Aa (y) perpendicular to the side surface. Extend.

なお、図１に示すように、ウエスト最深部４ａと胴裾部４ｂとの相互間の正面及び背面にそれぞれ、減圧吸収パネル４ｃが形成されている。   In addition, as shown in FIG. 1, the reduced pressure absorption panel 4c is formed in the front and back surface between the waist deepest part 4a and the trunk | drum skirt part 4b, respectively.

底部５は、図１，２に示すように、胴裾部４ｂから垂下することで構成される筒形をしてなり、その下端には平坦な接地面ｆが形成されている。なお、底部５は、図２(c)に示すように、その正面及び背面並びにその左右側面が平面をなし、その相互間がなだらかに湾曲する柱部によって連結されたほぼ八角柱状をなしている。   As shown in FIGS. 1 and 2, the bottom 5 has a cylindrical shape formed by hanging from the trunk skirt 4 b, and a flat ground surface f is formed at the lower end thereof. In addition, as shown in FIG.2 (c), the bottom part 5 has comprised the substantially octagonal column shape which the front and back, and the right-and-left side face comprised a plane, and was connected by the column part which curves between them gently. .

こうしたウエスト部を有するボトルの場合、積載時において口部２から荷重が加わることにより、或いは、ラベラーを用いてウエスト部４を含む胴部にラベルを装着することにより、当該ウエスト部４（特に、ウエスト最深部４ａ）の横断面形状が、図３(b)の実線で示す本来の楕円形状に対して、同図の破線で示すように、斜め楕円形状に変形してしまうことがある。   In the case of a bottle having such a waist portion, when the load is applied from the mouth portion 2 at the time of loading, or by attaching a label to the trunk portion including the waist portion 4 using a labeler, the waist portion 4 (particularly, The cross-sectional shape of the waist deepest part 4a) may be deformed into a slanted elliptical shape as shown by the broken line in FIG. 3 (b) with respect to the original elliptical shape shown by the solid line in FIG.

そのため、ウエスト部４には、ボトル１の軸線（以下、「ボトル軸線」という）Ｌ周りを周回する環状のリブ７が設けられている。ウエスト部４にリブ７を設ければ、ウエスト部４の機械的強度が高まるので、ウエスト部４に応力が集中することに伴う変形を抑制することができる。   Therefore, the waist portion 4 is provided with an annular rib 7 that circulates around the axis L of the bottle 1 (hereinafter referred to as “bottle axis”). If the rib 7 is provided in the waist part 4, the mechanical strength of the waist part 4 is increased, so that deformation accompanying stress concentration on the waist part 4 can be suppressed.

しかしながら、ボトル１は、そもそも機械的強度が低いポリ乳酸を含む樹脂からなるため、ウエスト部４にリブを設ける等して、当該リブの形状を幾何学的に変化させることによって機械的強度を高めるのにも限界がある。   However, since the bottle 1 is made of a resin containing polylactic acid having a low mechanical strength in the first place, the mechanical strength is increased by geometrically changing the shape of the rib, for example, by providing a rib on the waist 4. There are also limits.

そこで、リブ７を、図３(a)に示すように、ウエスト部４の一部４ｄをボトル１の内側に向かって曲率半径ｒ1で湾曲させると共に、ボトル軸線Ｌ周りを周回してなる環状の凹部とし、当該リブ（リブ７を形成するウエスト部４の一部４ａ）７の端部４ｅをそれぞれ、同図に示すように、ボトル１の外側に向かう曲率半径ｒ2で形成された曲面とすることで、当該凹部７を除くウエスト部４に対してなだらかに連なるように構成している。 Therefore, as shown in FIG. 3 (a), the rib 7 is formed by curving a part 4d of the waist portion 4 toward the inside of the bottle 1 with a radius of curvature r 1 and rotating around the bottle axis L. A curved surface formed with a radius of curvature r 2 toward the outside of the bottle 1 as shown in the figure, with each end 4e of the rib (a part 4a of the waist part 4 forming the rib 7) 7 being a recess. By doing so, the waist portion 4 excluding the concave portion 7 is configured to be smoothly connected.

かかる構成によれば、リブ７に対し外界から受ける応力の集中を抑止することができ、機械的強度が低いポリ乳酸を含む樹脂からなるボトルであっても一定程度の機械的強度の確保が可能となるが、前述のようにリブ７の形状が特定されてしまうことからボトル１に対するウエスト部４にリブ７を設けることによる効果を十分に発揮しきれない。   According to such a configuration, concentration of stress applied to the rib 7 from the outside can be suppressed, and a certain level of mechanical strength can be ensured even for a bottle made of a resin containing polylactic acid having low mechanical strength. However, since the shape of the rib 7 is specified as described above, the effect of providing the rib 7 on the waist portion 4 for the bottle 1 cannot be fully exhibited.

そこで、本発明では、さらに機械的強度の向上を図るためリブ７を、ボトル１の軸線Ｌに沿って上下方向に延在する範囲のうち、ウエスト最深部４ａを基点に、当該基点から上側に８ｍｍ離れた位置を上限とする一方、当該基点から下側に５ｍｍ離れた位置を下限とする範囲内に配置する。   Therefore, in the present invention, in order to further improve the mechanical strength, the rib 7 extends in the up and down direction along the axis L of the bottle 1 with the waist deepest part 4a as the base point and the upper side from the base point. While the upper limit is a position 8 mm away, the lower limit is a position 5 mm below the base point.

図４(a)〜(c)はそれぞれ、本発明に従い、ウエスト最深部４ａよりも下側の位置にリブ７を設けた形態、ウエスト最深部４ａにリブ７の最小径部（以下、「リブ最深部」という）７ａが一致する位置に当該リブ７を設けた形態及び、ウエスト最深部４ａよりも上側の位置にリブ７を設けた形態を模式的に示す斜視図である。   4 (a) to 4 (c) respectively show a configuration in which a rib 7 is provided at a position below the waist deepest portion 4a according to the present invention, and a minimum diameter portion of the rib 7 (hereinafter referred to as “rib” It is a perspective view which shows typically the form which provided the said rib 7 in the position which 7a (referred to as "deepest part") corresponds, and the form which provided the rib 7 in the position above the waist deepest part 4a.

また、図５(a),(b)はそれぞれ、本発明に従い、リブ７を配置するときのウエスト最深部４ａとの位置関係を模式的に示す正面図及び、同図(a)のウエスト最深部４ａ付近を拡大して、リブ７の位置との関係を模式的に示す要部拡大図である。   5 (a) and 5 (b) are a front view schematically showing the positional relationship with the deepest waist portion 4a when the rib 7 is arranged according to the present invention, and the deepest waist in FIG. 5 (a). It is a principal part enlarged view which expands the vicinity of the part 4a and shows the relationship with the position of the rib 7 typically.

上記範囲を詳述すると、図５(a)に示すように、接地面ｆからのウエスト最深部４ａの位置Ｌoを基準位置（以下、「基準位置Ｌo」という）として、同図(b)に示すように、基準位置Ｌoからボトル軸線Ｌに沿って下向きに５ｍｍ離れた位置Ｌ1とＬ５の間が好ましい範囲の下限値となり、基準位置Ｌoからボトル軸線Ｌに沿って上向きに８ｍｍ離れた位置Ｌ６が好ましい範囲の上限値となる。また、さらに好ましい範囲は下限値Ｌ1から上限値Ｌ2までの間の範囲（Ｌ1≦Ｌo≦Ｌ2）となる。 The above range will be described in detail. As shown in FIG. 5A, the position Lo of the waist deepest portion 4a from the ground contact surface f is defined as a reference position (hereinafter referred to as “reference position Lo”). As shown, the lower limit of the preferred range is between positions L 1 and L 5 that are 5 mm downward from the reference position Lo along the bottle axis L, and 8 mm upward from the reference position Lo along the bottle axis L. position L 6 is the upper limit of the preferred range. A more preferable range is a range between the lower limit L 1 and the upper limit L 2 (L 1 ≦ Lo ≦ L 2 ).

このため、リブ７については、図４に示すように、その最深部７ａが接地面ｆに対して配置される位置を、当該リブ７の位置（以下、「リブ位置」という）Ｌ7とすると、このリブ位置Ｌ7が、例えば、図５に示すように、より好ましい範囲である下限値Ｌ1から上限値Ｌ2までの間の範囲（Ｌ1≦Ｌ7≦Ｌ2）になるように配置すればよい。但し、本発明によれば、当該範囲（Ｌ1≦Ｌ7≦Ｌ2）中にリブ７を配置するに際し、リブ最深部７ａをウエスト最深部４ａに一致するようにすれば、ウエスト部４の機械的強度を最も高めることができる。このため、本形態に係るリブ７については、図１に示すように、そのリブ最深部７ａが、ウエスト最深部４ａに一致するように配置されている。 For this reason, as shown in FIG. 4, the position where the deepest portion 7 a is disposed with respect to the ground contact surface f is the position of the rib 7 (hereinafter referred to as “rib position”) L 7. For example, as shown in FIG. 5, the rib position L 7 is in a range between the lower limit value L 1 and the upper limit value L 2, which is a more preferable range (L 1 ≦ L 7 ≦ L 2 ). What is necessary is just to arrange. However, according to the present invention, when the rib 7 is arranged in the range (L 1 ≦ L 7 ≦ L 2 ), if the rib deepest portion 7a coincides with the waist deepest portion 4a, the waist portion 4 The mechanical strength can be maximized. For this reason, about the rib 7 which concerns on this form, as shown in FIG. 1, the rib deepest part 7a is arrange | positioned so that it may correspond with the waist deepest part 4a.

即ち、ポリ乳酸を含む樹脂を二軸延伸ブロー成形してなるボトル１において、本形態のように、その横断面形状を楕円形状とし、当該ボトル１の上部にドーム状の膨出部３を形成すると共に、この膨出部３の下側に、当該膨出部４に連なって内側にくびれたウエスト部４を形成し、
更に、このウエスト部４に、軸線Ｌ周りを周回する環状のリブ７を設ければ、当該ウエスト部４に応力が集中したときも、その形状がリブ７によって幾何学的に変化しているため、当該ウエスト部４の機械的強度を高めることができる。従って、本形態によれば、ウエスト部４に応力が集中することによって、その横断面形状が、本来の楕円形状に対して斜め楕円形状に変形するような現象の発生を抑制することができる。 That is, in the bottle 1 formed by biaxial stretching blow molding of a resin containing polylactic acid, the cross-sectional shape is elliptical as in this embodiment, and the dome-shaped bulging portion 3 is formed on the bottle 1. And forming a waist portion 4 constricted inward from the bulging portion 4 below the bulging portion 3,
Furthermore, if an annular rib 7 that circulates around the axis L is provided on the waist portion 4, the shape is geometrically changed by the rib 7 even when stress is concentrated on the waist portion 4. The mechanical strength of the waist part 4 can be increased. Therefore, according to the present embodiment, it is possible to suppress the occurrence of a phenomenon in which the stress is concentrated on the waist portion 4 so that the cross-sectional shape thereof is deformed into an oblique elliptical shape with respect to the original elliptical shape.

加えて、本形態によれば、当該リブ７を、ボトル軸線Ｌに沿って上下方向に延在する範囲のうち、ウエスト最深部４ａを基点に、上８ｍｍ〜下５ｍｍの範囲内に配置したことで、かかるリブ７の形状的な変化によって機械的強度を高めるのとは別に、当該リブ７の配置によっても、変形の起こり易いウエスト最深部４ａ付近の機械的強度を高めることができる。   In addition, according to the present embodiment, the rib 7 is arranged in the range of 8 mm above to 5 mm below from the waist deepest part 4a in the range extending in the vertical direction along the bottle axis L. Thus, apart from increasing the mechanical strength by the change in the shape of the rib 7, the mechanical strength in the vicinity of the waist deepest portion 4a where deformation easily occurs can be increased by the arrangement of the rib 7.

従って、本形態によれば、ウエスト部４に割れ等を生じさせることなく、機械的強度を高めるためのリブ７を設けることができ、これにより、当該ウエスト部４の機械的強度を効果的に高めることから、ウエスト部４への応力集中によって当該ウエスト部４に発生する変形を効果的に防止することができる。   Therefore, according to this embodiment, it is possible to provide the rib 7 for increasing the mechanical strength without causing cracks or the like in the waist portion 4, thereby effectively increasing the mechanical strength of the waist portion 4. Since it raises, the deformation | transformation which generate | occur | produces in the said waist part 4 by the stress concentration to the waist part 4 can be prevented effectively.

特に、本形態の如く、上記リブ７を、ウエスト部４の一部４ｄをボトル１の内側に向かって湾曲させた軸線Ｌ周りを周回してなる環状の凹部とすると共に、当該リブ７の端部４ｅをそれぞれ、かかるリブ７を除くウエスト部４に向かってなだらかに連なる曲面とすれば、リブ７に対する過度な応力集中を緩和することができる。   In particular, as in the present embodiment, the rib 7 is an annular recess formed around the axis L in which a portion 4d of the waist portion 4 is curved toward the inside of the bottle 1, and the end of the rib 7 If each of the portions 4e is a curved surface that gradually leads toward the waist portion 4 excluding the rib 7, excessive stress concentration on the rib 7 can be alleviated.

＜ボトルの屈曲強度＞
本発明に従うボトル１（ポリ乳酸含量：１００質量％）の口部２に対して平面の剛体を載せ置いて、当該ボトル１に荷重を負荷したときの屈曲強度を、リブの位置変化に応じて解析した結果を表１に示す。 <Bond bending strength>
A flat rigid body is placed on the mouth part 2 of the bottle 1 (polylactic acid content: 100% by mass) according to the present invention, and the bending strength when a load is applied to the bottle 1 depends on the change in the position of the rib. The analysis results are shown in Table 1.

Figure 2010137883
Figure 2010137883

なお、ボトル１には、内容量４００（グラム）の扁平ボトルを使用し、形成するリブ深さをｄ＝１ｍｍとした。また、リブ位置Ｌ7は、その下限値をＬ3＝１５mm（−１５mm）とし、基準位置Ｌoに向かって、Ｌ5＝１０mm（−１０mm）及びＬ1＝５mm（−５mm）、並びに、その上限値をＬ4＝１５mm（＋１５mm）として、Ｌ2＝５mm（＋５mm）及びＬ6＝１０mm（＋１０mm）とした。 The bottle 1 was a flat bottle having an internal capacity of 400 (grams), and the rib depth to be formed was d = 1 mm. The lower limit of the rib position L 7 is L 3 = 15 mm (−15 mm), and toward the reference position Lo, L 5 = 10 mm (−10 mm), L 1 = 5 mm (−5 mm), and The upper limit values were L 4 = 15 mm (+15 mm), L 2 = 5 mm (+5 mm), and L 6 = 10 mm (+10 mm).

加えて、屈曲強度は、ウエスト最深部４ａが斜め楕円変更を生じない限界値（Ｎ）で示し、併せて、当該限界値（Ｎ）が、リブ最深部７ａがウエスト最深部４ａと一致するときの当該限界値（Ｎ）に対する割合（％）を示す。   In addition, the bending strength is indicated by a limit value (N) at which the waist deepest portion 4a does not cause the oblique ellipse to change, and when the rib deepest portion 7a matches the waist deepest portion 4a. The ratio (%) with respect to the limit value (N) is shown.

表１を参照すれば明らかなように、ウエスト最深部４ａがリブ最深部７ａに一致するようにリブ７を配置した場合の屈曲強度を基準にすると、基準位置Ｌoをウエスト最深部４ａとする下限値Ｌ3（＝−１５mm）から上限値Ｌ4（＝＋１５mm）までの範囲（Ｌ3≦Ｌ7≦Ｌ4）内のうち、特に、下限値Ｌ1（＝−５mm）から上限値Ｌ2（＝＋５mm）までの範囲（Ｌ1≦Ｌ7≦Ｌ2）内であれば、ウエスト最深部４ａとリブ最深部７ａとを一致させたときに得られる屈曲強度の、９０％以上の高い屈曲強度を得ることができる。 As is clear from Table 1, when the rib 7 is arranged so that the waist deepest portion 4a coincides with the rib deepest portion 7a, the lower limit of setting the reference position Lo as the waist deepest portion 4a. In the range from the value L 3 (= −15 mm) to the upper limit value L 4 (= + 15 mm) (L 3 ≦ L 7 ≦ L 4 ), in particular, the lower limit value L 1 (= −5 mm) to the upper limit value L 2 If it is within the range up to (= + 5 mm) (L 1 ≦ L 7 ≦ L 2 ), a high bending strength of 90% or more of the bending strength obtained when the waist deepest portion 4a and the rib deepest portion 7a are matched. Strength can be obtained.

更に、リブ位置と座屈強度等との関係を詳細に解析したグラフを図６に示す。   Furthermore, the graph which analyzed in detail the relationship between a rib position, buckling strength, etc. is shown in FIG.

図６から明らかなように、リブ最深部７ａが下限値Ｌ1（＝−５mm）から上限値Ｌ2（＝＋５mm）までの範囲（Ｌ1≦Ｌ0≦Ｌ2）内のうちでも、特に、下限値Ｌ7（＝−２mm）から上限値Ｌ8（＝＋５mm）までの範囲（Ｌ1≦Ｌ0≦Ｌ2）内であれば、ウエスト最深部４ａとリブ最深部７ａとを一致させたときに得られる屈曲強度に近い高い屈曲強度を得ることができる。 As is apparent from FIG. 6, the rib deepest portion 7a is particularly within the range (L 1 ≦ L 0 ≦ L 2 ) from the lower limit value L 1 (= −5 mm) to the upper limit value L 2 (= + 5 mm). If it is within the range (L 1 ≦ L 0 ≦ L 2 ) from the lower limit L 7 (= −2 mm) to the upper limit L 8 (= + 5 mm), the waist deepest part 4a and the rib deepest part 7a are made to coincide. A high bending strength close to the bending strength obtained at the time can be obtained.
