Description

本発明は容器に関し、特に取り扱いやすい容器に関する。 The present invention relates to a container, and particularly to a container that is easy to handle.

液体（粘稠質のものも含む）の内容物が入れられる容器には、水平面に載置されたときに、水平断面が略楕円形で、正面視において鉛直方向に長く底面から鉛直上方に向かって一旦徐々に幅が大きくなった後にすぼまった形状のものや（例えば、特許文献１参照。）、図８に示すような水平断面が略正六角形の下部９１の上に周方向に形成された小さな溝９２を挟んで円筒状の上部９３が形成された鉛直方向に長い形状のものが広く知られている。
特開２００２−１７３１２３号公報（図１、図２等） When placed on a horizontal surface, the container in which the contents of liquid (including viscous ones) are placed has an approximately oval horizontal cross section, which is long in the vertical direction and vertically upward from the bottom in front view. Once the width has been gradually increased, the shape has become narrowed (see, for example, Patent Document 1), or a horizontal cross section as shown in FIG. 8 is formed on the substantially regular hexagonal lower portion 91 in the circumferential direction. A vertically long shape in which a cylindrical upper portion 93 is formed across a small groove 92 is widely known.
Japanese Patent Laid-Open No. 2002-173123 (FIG. 1, FIG. 2, etc.)

上述の容器に入れられる内容物が食品である場合には、冷蔵庫内で保存される場合が多い。この内容物入り容器が冷蔵庫から取り出されて湿気を有する外気に触れると容器の表面が結露することがある。結露することで容器の表面は滑りやすくなるため、上述のような形状の容器では手の平から滑り落ちる場合があった。 When the contents put in the container are foods, they are often stored in a refrigerator. When the container with the contents is taken out of the refrigerator and touched with the outside air having moisture, the surface of the container may be condensed. Since the surface of the container becomes slippery due to condensation, the container having the shape as described above sometimes slips from the palm.

本発明は上述の課題に鑑み、取り扱いやすい容器を提供することを目的とする。 An object of this invention is to provide the container which is easy to handle in view of the above-mentioned subject.

上記目的を達成するために、本発明の第１の態様に係る容器は、例えば図１に示すように、水平面ＨＰに載置されたときに上端面に開口１８ｈが形成される容器１０であって；水平面ＨＰに安定的に接する底面部１１と、底面部１１に連接して鉛直方向に伸びた筒状部１２とを有する座部１３であって、筒状部１２の水平断面（例えば図３（ｂ）参照）における正面側ＦＳの辺１２ｆｓとこれに対向する辺１２ｂｓとが他の４つの辺１２ｒｆ、１２ｒｂ、１２ｕｆ、１２ｕｂよりも長い略六角形に形成された座部１３と；座部１３に連接して鉛直上方に伸びたくびれ部１５であって、正面視においてくびれ１６が形成され、側面視（例えば図２参照）においてくびれが形成されていないくびれ部１５と；くびれ部１５に連接して鉛直上方に伸びた口頸部１９であって、水平断面（例えば図５参照）がくびれ部１５から離れるに連れて楕円形から円形に収束する口頸部１９とを備え；正面視において、くびれ１６より上方の最大幅ＷＨよりもくびれ１６より下方の最大幅ＷＬの方が大きく形成され；くびれ部１５は、正面及び背面に形成された略平らな平面帯１５ｐｆ（１５ｐｂ）と、平面帯１５ｐｆ（１５ｐｂ）の両側面側ＲＳ、ＵＳに形成された脇帯１５ｔｆ（１５ｔｂ）であって平面帯１５ｐｆ（１５ｐｂ）との間に鉛直方向に連なる角１５ｃが形成された脇帯１５ｔｆ（１５ｔｂ）とを有し、平面帯１５ｐｆ（１５ｐｂ）及び脇帯１５ｔｆ（１５ｔｂ）の両方を有する部分の水平断面（例えば図４（ｂ）参照）が全体的に六角形に形成され、鉛直方向に連なる角１５ｃが全体的に六角形（例えば図４（ｂ）参照）の角１５ｃに重なるように構成され；平面帯１５ｐｆ（１５ｐｂ）は口頸部１９の側が平面帯１５ｐｆ（１５ｐｂ）の外側よりも窪んで形成され、両方の脇帯１５ｔｆ（１５ｔｂ）は側面側ＲＳ、ＵＳ及び口頸部１９の側が脇帯１５ｔｆ（１５ｔｂ）の外側よりも窪んで形成され、各窪み１５ｄは一連に形成されている。ここで「開口が形成される」とは、容器に既に開口が形成されている場合のほか、将来開口が形成されることが予定されていることをも含む概念である。また「安定的に接する」とは、典型的には、容器を自立させることができるように接することをいう。また「平面帯の外側」とは、平面帯を含まない平面帯に隣接する部分であり、「脇帯の外側」とは、脇帯を含まない脇帯に隣接する部分である。 In order to achieve the above object, a container according to the first aspect of the present invention is a container 10 having an opening 18h formed on the upper end surface when placed on a horizontal plane HP as shown in FIG. A seat portion 13 having a bottom surface portion 11 that is in stable contact with the horizontal plane HP and a cylindrical portion 12 that is connected to the bottom surface portion 11 and extends in the vertical direction. 3 (b)), the seat portion 13 formed in a substantially hexagonal shape in which the side 12fs of the front side FS and the side 12bs opposed to the front side FS are longer than the other four sides 12rf, 12rb, 12uf, 12ub; A constricted portion 15 connected to the portion 13 and extending vertically upward, wherein the constricted portion 15 is formed in a constricted portion 16 in a front view and is not formed in a side view (for example, see FIG. 2); Connected vertically and stretched vertically upward A neck portion 19 having a horizontal section (see, for example, FIG. 5) that converges from an ellipse to a circle as it moves away from the neck portion 15; The maximum width WL below the constriction 16 is formed larger than the maximum width WH; the constricted portion 15 includes a substantially flat plane band 15pf (15pb) formed on the front surface and the back surface, and a plane band 15pf (15pb). Side bands 15tf (15tb) formed on both side surfaces RS and US, with side bands 15tf (15tb) formed with corners 15c in the vertical direction between the flat bands 15pf (15pb), The horizontal cross section (see, for example, FIG. 4B) of the portion having both the flat belt 15pf (15pb) and the side belt 15tf (15tb) is formed in a hexagonal shape as a whole, and the angle 15c continuous in the vertical direction is entirely formed. The flat band 15pf (15pb) is formed so that the side of the mouth-and-neck portion 19 is recessed from the outside of the flat band 15pf (15pb), Both side belts 15tf (15tb) are formed such that the side surface RS, US and the side of the mouth and neck portion 19 are recessed from the outside of the side belt 15tf (15tb), and each recess 15d is formed in series. Here, “the opening is formed” is a concept including not only the case where the opening is already formed in the container but also that the opening is scheduled to be formed in the future. In addition, “stable contact” typically refers to contact so that the container can stand on its own. The “outside of the flat band” is a part adjacent to the flat band not including the flat band, and the “outside of the side band” is a part adjacent to the side band not including the side band.

このように構成すると、くびれ部が手の平にフィットして容器を把持しやすいと共に、くびれよりも底面部側の最大幅が大きいので容器を把持して逆さにしても落としにくく、また、くびれ部に平面帯が形成されているために曲面に形成されているよりも容器を把持したときの手との接触面積を増加させることができるので、取り扱いやすい容器となる。また、座部の水平断面が略六角形に形成されているので座部から平面帯へのつながりがスムーズになると共に、平面帯及び脇帯に窪みが形成されているので水平断面が楕円形に形成された口頸部と平面帯及び脇帯とを区別してそれぞれの役割を効果的に発揮させることができる。なお、口頸部のくびれ部に近い水平断面が楕円形に形成されているために内容物の充填容量の減少を抑制することができる。 With this configuration, the constricted part fits the palm of the hand and is easy to grip the container, and the maximum width on the bottom side is larger than the constricted part, so it is hard to drop even if the container is gripped and turned upside down. Since the flat band is formed, the contact area with the hand when the container is gripped can be increased as compared with the case where the container is formed on the curved surface, so that the container is easy to handle. In addition, since the horizontal cross section of the seat portion is formed in a substantially hexagonal shape, the connection from the seat portion to the flat belt is smooth, and the hollow is formed in the flat belt and the side belt so that the horizontal cross section is elliptical. The formed mouth-neck part can be distinguished from the flat band and the side band, and each role can be effectively exhibited. In addition, since the horizontal cross section close | similar to the constriction part of a mouth neck part is formed in the ellipse, the reduction | decrease of the filling capacity | capacitance of the content can be suppressed.

また、本発明の第２の態様に係る容器は、例えば図１に示すように、上記本発明の第１の態様に係る容器１０において、くびれ部１５の正面１５ｐｆと背面１５ｐｂとが接近するように変形させたときに弾性変形をするように構成されている。 Further, the container according to the second aspect of the present invention is such that, for example, as shown in FIG. 1, in the container 10 according to the first aspect of the present invention, the front surface 15pf and the rear surface 15pb of the constricted portion 15 approach each other. It is configured to be elastically deformed when being deformed.

このように構成すると、通常の使用態様において、把持しやすい原形を維持することができる。また、くびれ部に平面帯が形成されていることと相俟って、内容物を開口から出すための押圧力を軽減することができる。 If comprised in this way, in the normal use aspect, the original form which is easy to hold | grip can be maintained. In addition, combined with the formation of a flat band at the constricted portion, it is possible to reduce the pressing force for taking out the contents from the opening.

また、本発明の第３の態様に係る容器は、例えば図７（ａ）に示すように、上記本発明の第１の態様又は第２の態様に係る容器において、開口１８ｈが、容器１０と一体に形成された袋部２１で封止されて構成されている。 In addition, the container according to the third aspect of the present invention is the container according to the first aspect or the second aspect of the present invention described above, for example, as shown in FIG. It is configured to be sealed with a bag portion 21 formed integrally.

このように構成すると、容器内が外気にさらされることを、内容物が充填される直前まで回避することが可能となり、容器内を衛生的に保つことが可能となる。 If comprised in this way, it will become possible to avoid exposing the inside of a container to external air until just before the contents are filled, and it becomes possible to keep the inside of a container hygienic.

また、本発明の第４の態様に係る容器は、例えば図７（ｂ）に示すように、上記本発明の第１の態様又は第２の態様に係る容器において、開口１８ｈを覆うように、嵌着又は螺着により、蓋２２又は中栓が取り付けられて構成されている。 In addition, the container according to the fourth aspect of the present invention covers, for example, the opening 18h in the container according to the first aspect or the second aspect of the present invention as shown in FIG. The lid 22 or the inner plug is attached by fitting or screwing.

このように構成すると、蓋又は中栓を容器から取り外しやすく、内容物を充填しやすい容器となる。 If comprised in this way, it will become a container which is easy to remove a lid | cover or an inside stopper from a container, and is easy to fill with the contents.

本発明によれば、くびれ部が手の平にフィットして容器を把持しやすいと共に、くびれよりも底面部側の最大幅が大きいので容器を把持して逆さにしても落としにくく、また、くびれ部に平面帯が形成されているために曲面に形成されているよりも容器を把持したときの手との接触面積を増加させることができる。それゆえ、取り扱いやすい容器となる。 According to the present invention, the constricted part fits the palm easily to grip the container, and since the maximum width on the bottom side is larger than the constricted part, it is difficult to drop even if the container is gripped and turned upside down. Since the flat band is formed, the contact area with the hand when the container is grasped can be increased as compared with the case where the container is formed on the curved surface. Therefore, the container is easy to handle.

以下、図面を参照して本発明の実施の形態について説明する。なお、各図において互いに同一又は相当する部材には同一あるいは類似の符号を付し、重複した説明は省略する。 Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar members are denoted by the same or similar reference numerals, and redundant description is omitted.

まず図１及び図２を参照して、本発明の実施の形態に係る容器１０を説明する。図１は容器１０の正面図、図２は容器１０の右側面図である。容器１０は、背面視において正面視と同様に現れ、左側面視において右側面視と同様に現れる。つまり、背面の輪郭は正面の輪郭と同様であり、左側面の輪郭は右側面の輪郭と同様である。図１及び図２に示す容器１０は、水平面ＨＰに載置した状態を現しており、以下の説明においても特に断りがない場合は、容器１０を水平面ＨＰに載置した状態を前提とする。容器１０は、本実施の形態では、種類の異なる合成樹脂を多層積層した積層体で形成されている。以下に主として容器１０の形状を説明するが、説明の便宜上、一体に形成されている容器１０を、水平面ＨＰに接する底面部１１を有する座部１３と、座部１３の直上に位置するくびれ部１５と、くびれ部１５の直上に位置する口頸部１９とに大まかに区別して説明する。 First, with reference to FIG.1 and FIG.2, the container 10 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a front view of the container 10, and FIG. 2 is a right side view of the container 10. The container 10 appears in the rear view as in the front view, and appears in the left side view as in the right side view. That is, the back contour is the same as the front contour, and the left side contour is the same as the right side contour. The container 10 shown in FIG.1 and FIG.2 has shown the state mounted in the horizontal surface HP, and the state which mounted the container 10 in the horizontal surface HP is assumed unless there is particular notice in the following description. In the present embodiment, the container 10 is formed of a laminate in which different types of synthetic resins are laminated. Although the shape of the container 10 will be mainly described below, for convenience of explanation, the integrally formed container 10 includes a seat portion 13 having a bottom surface portion 11 in contact with the horizontal plane HP and a constricted portion located immediately above the seat portion 13. 15 and the mouth-and-neck portion 19 positioned immediately above the constricted portion 15 will be roughly described.

図３（ａ）に示す底面図、及び図３（ｂ）に示す座部１３に係る図１におけるIIIＢ−IIIＢ断面図を、図１及び図２と併せて参照して、座部１３について説明する。座部１３は、底面部１１と、底面部１１から鉛直上方に伸びる筒状部１２とを有している。底面部１１は、略六角形に形成されている。ここでいう「略六角形」は、辺が直線でない場合や隣り合う辺の間に角が現れていなくとも全体を概観すると六角形と認識できる形である。底面部１１を形成する略六角形は、正面側（ＦＳ）の辺１１ｆｓと、これと平行に対向する背面側（ＢＳ）の辺１１ｂｓとが同じ長さに形成され、これら２つの辺１１ｆｓ、１１ｂｓを左側面側（ＵＳ）でつなぐ２つの辺１１ｕｆ、１１ｕｂと右側面側（ＲＳ）でつなぐ２つの辺１１ｒｆ、１１ｒｂとの合計４つは、それぞれ同じ長さで辺１１ｆｓよりも短く形成されている。 The seat 13 will be described with reference to the bottom view shown in FIG. 3A and the IIIB-IIIB sectional view in FIG. 1 relating to the seat 13 shown in FIG. 3B together with FIGS. To do. The seat portion 13 includes a bottom surface portion 11 and a cylindrical portion 12 extending vertically upward from the bottom surface portion 11. The bottom surface part 11 is formed in a substantially hexagonal shape. The “substantially hexagonal shape” mentioned here is a shape that can be recognized as a hexagonal shape when the sides are not straight or when there is no corner between adjacent sides. The substantially hexagonal shape forming the bottom surface portion 11 is such that the front side (FS) side 11fs and the back side (BS) side 11bs opposed in parallel to each other are formed in the same length, and these two sides 11fs, A total of four of the two sides 11uf, 11ub that connect 11bs on the left side (US) and the two sides 11rf, 11rb that connect on the right side (RS) are the same length and shorter than the side 11fs. ing.

底面部１１は、水平面ＨＰに接触する部分を含む周底部１１ｅが略六角形の外周に沿って幅を持って形成され、周底部１１ｅの内側には容器１０の内側に凹んだ凹部１１ｄが形成されている。周底部１１ｅの幅は、例えば六角形の短軸の長さ（換言すれば互いに平行な辺１１ｆｓと辺１１ｂｓとの最短距離）の１／６〜１／４程度に形成されているとよい。このような幅を持つ周底部１１ｅは、略六角形の底面部１１の外周に沿って環状につながっている。また、凹部１１ｄが形成されていることで、底面部１１の中央部が何らかの要因で容器１０の外側に膨らむことに起因する安定性の欠如を防ぐことができ、ひいては容器１０を水平面ＨＰに載置したときの安定性を増すことができる。底面部１１は周底部１１ｅの外縁全体から筒状部１２に連接しており、周底部１１ｅと筒状部１２とが連接する部分（水平に広がる周底部１１ｅと鉛直方向に伸びる筒状部１２とがつながる部分）は丸みを帯びている。したがって、周底部１１ｅの外縁の丸みを帯びた部分は水平面ＨＰに接触せず、換言すると水平面ＨＰに接触するのは周底部１１ｅの一部となっている。 The bottom surface portion 11 includes a peripheral bottom portion 11e including a portion in contact with the horizontal plane HP and having a width along a substantially hexagonal outer periphery, and a concave portion 11d recessed inside the container 10 is formed inside the peripheral bottom portion 11e. Has been. The width of the peripheral bottom portion 11e is preferably, for example, about 1/6 to 1/4 of the length of the short axis of the hexagon (in other words, the shortest distance between the side 11fs and the side 11bs parallel to each other). The peripheral bottom portion 11e having such a width is connected in an annular shape along the outer periphery of the substantially hexagonal bottom surface portion 11. Further, since the recess 11d is formed, it is possible to prevent the lack of stability due to the central portion of the bottom surface portion 11 expanding outside the container 10 for some reason, and thus the container 10 is mounted on the horizontal plane HP. The stability when placed can be increased. The bottom surface portion 11 is connected to the cylindrical portion 12 from the entire outer edge of the peripheral bottom portion 11e, and a portion where the peripheral bottom portion 11e and the cylindrical portion 12 are connected (the peripheral bottom portion 11e extending horizontally and the cylindrical portion 12 extending in the vertical direction). The part that is connected to) is rounded. Therefore, the rounded portion of the outer edge of the peripheral bottom portion 11e does not contact the horizontal plane HP. In other words, the portion that contacts the horizontal plane HP is a part of the peripheral bottom portion 11e.

筒状部１２は、上述のように、周底部１１ｅの外縁全体に連接しており、周底部１１ｅから鉛直上方に伸びている。筒状部１２は、水平断面が略六角形に形成されている。ここでいう「略六角形」も、全体を概観すると六角形と認識できる形であり、辺が直線でない場合や隣り合う辺の間に角が現れずに丸みを帯びている場合であっても概観すると六角形と認識できるものを含む概念である。筒状部１２の水平断面に現れる略六角形は、正面側（ＦＳ）の正面辺１２ｆｓと、これと平行に対向する背面側（ＢＳ）の背面辺１２ｂｓとが同じ長さに形成されている。正面辺１２ｆｓと背面辺１２ｂｓとを左側面側（ＵＳ）でつなぐ２つの辺１２ｕｆ、１２ｕｂ、及び右側面側（ＲＳ）でつなぐ２つの辺１２ｒｆ、１２ｒｂの合計４つは、それぞれ同じ長さで正面辺１２ｆｓ及び背面辺１２ｂｓよりも短く形成されている。筒状部１２は、正面視において略同じ幅で上方に伸びており、側面視においても幅の変化がないように形成されている。筒状部１２の鉛直方向の長さは、水平断面の略六角形の短軸の長さの１／３〜３／３程度に形成されているとよい。 As described above, the cylindrical portion 12 is connected to the entire outer edge of the peripheral bottom portion 11e, and extends vertically upward from the peripheral bottom portion 11e. The cylindrical part 12 is formed in a substantially hexagonal horizontal cross section. The "substantially hexagonal shape" here is a shape that can be recognized as a hexagonal shape when viewed as a whole, even if the sides are not straight or rounded with no corners appearing between adjacent sides. It is a concept that includes what can be recognized as a hexagon when overviewed. The substantially hexagonal shape that appears in the horizontal cross section of the cylindrical portion 12 is such that the front side (FS) front side 12fs and the back side (BS) back side 12bs facing in parallel are formed to have the same length. . A total of four of the two sides 12uf, 12ub connecting the front side 12fs and the back side 12bs on the left side (US) and the two sides 12rf, 12rb connecting on the right side (RS) have the same length. It is shorter than the front side 12fs and the back side 12bs. The cylindrical portion 12 extends upward with substantially the same width when viewed from the front, and is formed so that there is no change in width when viewed from the side. The length of the cylindrical portion 12 in the vertical direction is preferably about 1/3 to 3/3 of the length of the short axis of the substantially hexagonal horizontal section.

次に図４（ａ）に示すくびれ部１５の座部１３との連接部分に係る図１におけるIVＡ−IVＡ断面図、及び図４（ｂ）に示すくびれ部１５に係る図１におけるIVＢ−IVＢ断面図を、図１及び図２と併せて参照して、くびれ部１５について説明する。くびれ部１５は、筒状部１２につながっており、筒状部１２から鉛直上方に伸びている。くびれ部１５が筒状部１２とつながっている部分は、その部分の水平断面における全周にわたってつながっている。くびれ部１５は、正面視（図１参照）における幅が、下方から上方に行くに連れて徐々に小さくなった後に徐々に大きくなるように形成されている。換言すると、くびれ部１５の正面視における輪郭にはくびれ１６が形成されている。他方くびれ部１５は、側面視（図２参照）における輪郭にはくびれが形成されていない。側面視における輪郭にくびれが形成されていないことにより、充填可能な内容物の容量が減少することを抑制することができる。くびれ１６は、一方の側面側に注目したときに、くびれ部１５の谷の底と山の頂部との水平距離が２ｍｍ〜１２ｍｍ程度とすると、把持する際に親指の腹（付け根）の部分がくびれ１６にフィットするため好適である。くびれ部１５の谷の底と山の頂部との水平距離は、５ｍｍや８ｍｍとしてもよい。 Next, the IVA-IVA cross-sectional view in FIG. 1 related to the connecting portion of the constricted portion 15 to the seat portion 13 shown in FIG. 4A and the IVB-IVB in FIG. 1 related to the constricted portion 15 shown in FIG. The constricted portion 15 will be described with reference to the cross-sectional views in conjunction with FIGS. 1 and 2. The constricted portion 15 is connected to the tubular portion 12 and extends vertically upward from the tubular portion 12. The portion where the constricted portion 15 is connected to the cylindrical portion 12 is connected over the entire circumference in the horizontal cross section of the portion. The constricted portion 15 is formed so that the width in the front view (see FIG. 1) gradually increases after gradually decreasing from the lower side to the upper side. In other words, the constriction 16 is formed in the outline of the constricted portion 15 in a front view. On the other hand, the constricted portion 15 is not formed with a constriction in the outline in a side view (see FIG. 2). Since the constriction in the side view is not formed, it is possible to suppress a decrease in the volume of the contents that can be filled. When the neck 16 is focused on one side, and the horizontal distance between the bottom of the valley of the constricted portion 15 and the top of the mountain is about 2 mm to 12 mm, the belly (base) portion of the thumb is This is suitable for fitting the constriction 16. The horizontal distance between the bottom of the valley of the constricted portion 15 and the top of the mountain may be 5 mm or 8 mm.

くびれ部１５は、水平断面が概ね六角形に形成されている（図４参照）。くびれ部１５における水平断面に現れる概ね六角形は、正面側（ＦＳ）の正面辺１５ｆｓと、これと平行に対向する背面側（ＢＳ）の背面辺１５ｂｓとが同じ長さに形成されている。正面辺１５ｆｓ及び背面辺１５ｂｓは、左側面側（ＵＳ）では２つの辺１５ｕｆ、１５ｕｂで接続されており、右側面側（ＲＳ）では２つの辺１５ｒｆ、１５ｒｂで接続されている。正面辺１５ｆｓと背面辺１５ｂｓとを接続する合計４つの辺１５ｕｆ、１５ｕｂ、１５ｒｆ、１５ｒｂは、それぞれ同じ長さに形成されている。くびれ部１５の座部１３との連接部分の水平断面（図４（ａ）参照）は、略六角形に形成されており、この部分の略六角形の正面辺１５ｆｓ及び背面辺１５ｂｓは、その他の合計４つの辺１５ｕｆ、１５ｕｂ、１５ｒｆ、１５ｒｂのそれぞれよりも長く形成されている。 The constricted portion 15 has a horizontal section that is generally hexagonal (see FIG. 4). The generally hexagonal shape that appears in the horizontal section of the constricted portion 15 is such that the front side (FS) front side 15fs and the back side (BS) back side 15bs facing in parallel with each other are formed in the same length. The front side 15fs and the back side 15bs are connected by two sides 15uf and 15ub on the left side (US), and are connected by two sides 15rf and 15rb on the right side (RS). A total of four sides 15uf, 15ub, 15rf, and 15rb connecting the front side 15fs and the back side 15bs are formed to have the same length. The horizontal section (see FIG. 4A) of the connection portion of the constricted portion 15 with the seat portion 13 is formed in a substantially hexagonal shape, and the substantially hexagonal front side 15fs and back side 15bs of this portion are the other parts. Are formed longer than each of the four sides 15uf, 15ub, 15rf, and 15rb.

くびれ部１５は、正面辺１５ｆｓを鉛直方向に連ねて形成される面の少なくとも一部に、略平らな面である平面帯としての正面平面帯１５ｐｆが形成されている。正面平面帯１５ｐｆは、鉛直方向に長い帯状に形成されている。帯状に形成された正面平面帯１５ｐｆの両脇には、それぞれ脇帯としての正面脇帯１５ｔｆが角１５ｃを介して接続されている。角１５ｃは、鉛直方向に連なっている。角１５ｃは、正面辺１５ｆｓと辺１５ｒｆとが出会う角、及び正面辺１５ｆｓと辺１５ｕｆとが出会う角に相当する。角１５ｃは丸みを帯びていてもよい。正面平面帯１５ｐｆ及び正面脇帯１５ｔｆを合わせた領域は、その合わせた領域の両側及び上部が窪み１５ｄを介してその周囲と区画されている。窪み１５ｄの概観は、本実施の形態では馬蹄形に形成されている。本実施の形態における窪み１５ｄは、正面平面帯１５ｐｆの部分では上部（口頸部１９側）に、正面脇帯１５ｔｆの部分では正面平面帯１５ｐｆとは反対側の側面及び上部（口頸部１９側）に、一連に形成されている。一連の窪み１５ｄを境界として、正面平面帯１５ｐｆ及び正面脇帯１５ｔｆを合わせた領域が、その周囲（外側）よりも容器１０の内側に段差をもって窪んでいる。正面平面帯１５ｐｆ及び正面脇帯１５ｔｆを合わせた領域の下部（座部１３側）は、窪みが形成されておらず滑らかにその周囲（外側）とつながっている。なお、背面視においても、正面視において相当する各部位と同様の要領で、平面帯としての背面平面帯１５ｐｂ、脇帯としての背面脇帯１５ｔｂ、角１５ｃ、窪み１５ｄがそれぞれ形成されている。 The constricted portion 15 is formed with a front plane band 15pf as a plane band which is a substantially flat surface on at least a part of a surface formed by connecting the front sides 15fs in the vertical direction. The front plane belt 15pf is formed in a belt shape that is long in the vertical direction. Front side bands 15tf as side bands are connected to both sides of the front plane band 15pf formed in a band shape via corners 15c. The corner 15c is continuous in the vertical direction. The corner 15c corresponds to a corner where the front side 15fs and the side 15rf meet and a corner where the front side 15fs and the side 15uf meet. The corner 15c may be rounded. In the region where the front plane belt 15pf and the front side belt 15tf are combined, both sides and the upper portion of the combined region are partitioned from the periphery thereof via a recess 15d. The appearance of the recess 15d is formed in a horseshoe shape in the present embodiment. The recess 15d in the present embodiment has an upper portion (mouth neck portion 19 side) in the front plane belt 15pf portion, and a side surface and upper portion (mouth neck portion 19) on the opposite side to the front flat belt 15pf in the front side belt portion 15tf. Side). A region including the front plane belt 15pf and the front side belt 15tf with the series of depressions 15d as a boundary is recessed with a step inside the container 10 from the periphery (outside). The lower part (the seat portion 13 side) of the region including the front plane belt 15pf and the front side belt 15tf is smoothly connected to the periphery (outside) without a depression. In back view, a back plane belt 15pb as a plane belt, a back side belt 15tb as a side belt, a corner 15c, and a recess 15d are formed in the same manner as the corresponding parts in front view.

くびれ部１５の、正面平面帯１５ｐｆ及び正面脇帯１５ｔｆの両方を有する部分の水平断面（図４（ｂ）参照）は、全体的に六角形に形成されている。ここでいう「全体的に六角形」は、全体を概観すると六角形と認識できる形であり、辺が直線でない場合や一辺の途中に凹凸がある場合、隣り合う辺の間に角が現れずに丸みを帯びている場合であっても概観すると六角形と認識できるものを含む概念である。「全体的に六角形」は、一辺の途中に凹凸がある場合を含んでいる分、「略六角形」よりも広い概念である。また、上述の「概ね六角形」は、「略六角形」及び「全体的に六角形」を包括して呼称したものである。なお、正面平面帯１５ｐｆ及び正面脇帯１５ｔｆの両方を有する部分の水平断面は、背面平面帯１５ｐｂ及び背面脇帯１５ｔｂの両方をも有することとなる。正面平面帯１５ｐｆ及び正面脇帯１５ｔｆの両方を有する部分の水平断面に現れる全体的に六角形は、正面辺１５ｆｓが正面平面帯１５ｐｆ上に、背面辺１５ｂｓが背面平面帯１５ｐｂ上に、それぞれ位置するようになっている。正面辺１５ｆｓは、左側面側（ＵＳ）が角１５ｃを介して辺１５ｕｆと接続され、右側面側（ＲＳ）が角１５ｃを介して辺１５ｒｆと接続されている。背面辺１５ｂｓは、左側面側（ＵＳ）が角１５ｃを介して辺１５ｕｂと接続され、右側面側（ＲＳ）が角１５ｃを介して辺１５ｒｂと接続されている。つまり、角１５ｃは、正面平面帯１５ｐｆ及び正面脇帯１５ｔｆの両方を有する部分の水平断面に現れる「全体的に六角形」の角に相当し、正面平面帯１５ｐｆと正面脇帯１５ｔｆとの間で鉛直方向に連なる角にも相当する。背面も同様である。辺１５ｕｆ及び辺１５ｒｆは、正面辺１５ｆｓ側の一部が正面脇帯１５ｔｆを兼ねている。正面平面帯１５ｐｆ及び正面脇帯１５ｔｆの両方を有する部分の水平断面では、辺１５ｕｆ及び辺１５ｒｆのそれぞれの途中に窪み１５ｄが存在するが、「全体的に六角形」においては六角形の一辺とみなすこととしている。他方、背面側（ＢＳ）においては、背面辺１５ｂｓの両側でそれぞれつながる辺１５ｕｂ及び辺１５ｒｂは、背面辺１５ｂｓ側の一部が背面脇帯１５ｔｂを兼ねている。辺１５ｕｂ及び辺１５ｒｂのそれぞれの途中にも窪み１５ｄが存在するが、「全体的に六角形」における六角形の一辺とみなすこととしている。本実施の形態では、くびれ１６付近の水平断面における全体的に六角形の各辺が、略等しい長さに形成されている。 The horizontal cross section (see FIG. 4B) of the portion having both the front plane belt 15pf and the front side belt 15tf of the constricted portion 15 is formed in a hexagonal shape as a whole. The term “generally hexagonal” as used here is a shape that can be recognized as a hexagon when viewed as a whole. If the side is not a straight line or has irregularities in the middle of one side, no corners appear between adjacent sides. Even if it is rounded, it is a concept including what can be recognized as a hexagon when viewed roughly. “Overall hexagonal” is a broader concept than “substantially hexagonal” because it includes a case where there is an unevenness in the middle of one side. Further, the above-mentioned “substantially hexagonal” is a generic term for “substantially hexagonal” and “generally hexagonal”. The horizontal cross section of the portion having both the front plane belt 15pf and the front side belt 15tf also has both the back plane belt 15pb and the back side belt 15tb. The overall hexagonal shape that appears in the horizontal section of the portion having both the front plane band 15pf and the front side band 15tf is such that the front side 15fs is positioned on the front plane band 15pf and the back side 15bs is positioned on the back plane band 15pb. It is supposed to be. The front side 15fs is connected to the side 15uf on the left side (US) via a corner 15c and to the side 15rf on the right side (RS) via a corner 15c. The back side 15bs has a left side (US) connected to the side 15ub via a corner 15c and a right side (RS) connected to the side 15rb via a corner 15c. That is, the corner 15c corresponds to a “generally hexagonal” corner that appears in the horizontal cross section of the portion having both the front plane band 15pf and the front side band 15tf, and between the front plane band 15pf and the front side band 15tf. This also corresponds to the angle that runs in the vertical direction. The same applies to the back side. Part of the side 15uf and the side 15rf on the front side 15fs side also serves as the front side belt 15tf. In the horizontal cross section of the portion having both the front plane belt 15pf and the front side belt 15tf, there is a recess 15d in the middle of each of the side 15uf and the side 15rf. It is supposed to be considered. On the other hand, on the back side (BS), a part of the side 15 ub and side 15 rb connected on both sides of the back side 15 bs also serves as the back side band 15 tb. Although there is a recess 15d in the middle of each of the side 15ub and the side 15rb, it is assumed that it is regarded as one side of the hexagon in the “overall hexagon”. In the present embodiment, the sides of the overall hexagon in the horizontal cross section near the constriction 16 are formed to have substantially the same length.

次に図５（ａ）に示す口頸部１９に係る図１におけるＶＡ−ＶＡ断面図、及び図５（ｂ）に示す口頸部１９に係る図１におけるＶＢ−ＶＢ断面図を、図１及び図２と併せて参照して、口頸部１９について説明する。口頸部１９は、くびれ部１５に連接してくびれ部１５から鉛直上方に伸びる口頸胴部１７と、くびれ部１５に連接する側とは反対側で口頸胴部１７に接続された口頸螺部１８とを有している。口頸胴部１７は、下部の水平断面が図５（ａ）に示されるように楕円形に形成されており、上部の水平断面が図５（ｂ）に示されるように円形に形成されている。つまり、口頸胴部１７は、くびれ部１５との接続部分付近では楕円形に形成されており、上方に行くに連れて（くびれ部１５から離れるに連れて）円形に収束するように構成されている。ここで、「楕円形から円形に収束する」とは、楕円形から円形への変化が段差なく滑らかに移り変わっていくことを意味している。段差なく滑らかに移り変われば、楕円形から円形へ変化する割合は一定でも一定でなくてもよく、図１に示すようにくびれ部１５との接続部分から上方に行くに連れて楕円形から円形に変化する割合が小さくなるように形成されていてもよい。口頸胴部１７の高さ方向に任意の位置における水平断面に現れる円形又は楕円形の中心（楕円形の場合は楕円の長軸と短軸との交点を中心とする）を連ねると、鉛直に伸びるように構成されている。 Next, the VA-VA sectional view in FIG. 1 relating to the mouth and neck portion 19 shown in FIG. 5A and the VB-VB sectional view in FIG. 1 relating to the mouth neck portion 19 shown in FIG. The mouth and neck portion 19 will be described with reference to FIG. The mouth and neck part 19 is connected to the neck part 15 and is connected to the mouth and neck part 17 on the side opposite to the side connected to the neck part 15. The mouth neck part 17 extends vertically upward from the neck part 15. It has a neck screw part 18. As shown in FIG. 5 (a), the mouth / cervical torso part 17 is formed in an elliptical shape as shown in FIG. 5 (a), and the upper horizontal section is formed in a circle as shown in FIG. 5 (b). Yes. That is, the mouth-and-neck body portion 17 is formed in an oval shape in the vicinity of the connection portion with the constricted portion 15, and is configured to converge into a circle as it goes upward (as it moves away from the constricted portion 15). ing. Here, “converging from an ellipse to a circle” means that the change from an ellipse to a circle smoothly changes without a step. If it changes smoothly without a step, the rate of change from an elliptical shape to a circular shape does not have to be constant or constant. As shown in FIG. 1, the elliptical shape changes to a circular shape as it goes upward from the connecting portion with the constricted portion 15. It may be formed so that the rate of change to becomes smaller. When the center of a circle or ellipse appearing in a horizontal cross section at an arbitrary position in the height direction of the mouth-and-neck body part 17 (in the case of an ellipse, the center is the intersection of the major axis and the minor axis of the ellipse) It is configured to extend.

口頸螺部１８は、円筒状に形成されており、この円筒の仮想軸が口頸胴部１７の水平断面に現れる円形又は楕円形の中心を貫く仮想軸と一致するように設けられている。口頸螺部１８は、外周面に螺旋状の突起１８ｐが形成されている。口頸螺部１８の上面（口頸螺部１８の口頸胴部１７側とは反対の端面）には、内容物（不図示）の出入りが可能な開口１８ｈが形成されている。 The mouth-and-neck screw portion 18 is formed in a cylindrical shape, and is provided so that the imaginary axis of this cylinder coincides with the imaginary axis that passes through the center of a circle or ellipse that appears in the horizontal section of the mouth-and-neck body portion 17. . The mouth-and-neck screw portion 18 has a spiral projection 18p formed on the outer peripheral surface. An opening 18h through which contents (not shown) can enter and exit is formed on the upper surface of the mouth-and-neck screw 18 (the end surface opposite to the mouth-and-neck body 17 side of the mouth-and-neck screw 18).

これまで各部位ごとに説明してきた容器１０を全体的にみると、正面視において、くびれ１６より上方の最大幅である上方最大幅ＷＨよりも、くびれ１６より下方の最大幅である下方最大幅ＷＬの方が大きくなるように形成されている。内容物が充填されている容器１０を把持する場合において、容器１０を逆さにした状態（開口１８ｈが下向きになった状態（図６参照））で手から滑り落下したときの方が、開口１８ｈが上向きになった状態で落下したときよりも、一般に被害が大きい（内容物の意図しない吐出量が多い）。上方最大幅ＷＨよりも下方最大幅ＷＬを大きくすることにより、くびれ部１５を把持して容器１０を逆さにした状態で手から落下することを抑制できる。下方最大幅ＷＬは、上方最大幅ＷＨの例えば１．０５倍〜２．０倍程度に形成されていると手から落下することを抑制でき、特には１．０５倍〜１．５倍程度が好適である。また、容器１０を把持して逆向きにしたときの落下防止の観点から下限を１．１倍程度、美感の観点から上限を１．３倍程度とするとよく、１．１５倍あるいは１．２倍程度として落下防止と美感との均衡を保つようにしてもよい。 When the container 10 described so far for each part is viewed as a whole, the lower maximum width which is the maximum width below the constriction 16 is higher than the upper maximum width WH which is the maximum width above the constriction 16 in a front view. WL is formed to be larger. When gripping the container 10 filled with the contents, the opening 18h is when the container 10 is slid down from the hand with the container 10 turned upside down (the state where the opening 18h faces downward (see FIG. 6)). Generally, the damage is greater than when it is dropped in a state where it is facing upward (the amount of unintentional discharge of the contents is large). By making the lower maximum width WL larger than the upper maximum width WH, it is possible to prevent the container 10 from falling from the hand while holding the constricted portion 15 and upside down. If the lower maximum width WL is formed to be, for example, about 1.05 to 2.0 times the upper maximum width WH, it can be prevented from falling from the hand, and in particular, about 1.05 to 1.5 times. Is preferred. In addition, the lower limit is preferably about 1.1 times from the viewpoint of preventing falling when the container 10 is held in the opposite direction, and the upper limit is about 1.3 times from the viewpoint of aesthetics, and may be 1.15 times or 1.2 times. You may make it keep the balance of fall prevention and aesthetics as about twice.

容器１０は、窪み１５ｄの最上部の高さの水平面をくびれ部１５と口頸部１９との境界と規定し（窪み１５ｄはくびれ部１５に属することとしている）、窪み１５ｄの最下部の高さよりもやや下側（例えば２ｍｍ〜１０ｍｍ下側）の高さの水平面をくびれ部１５と座部１３との境界と規定することとしている。本実施の形態では、下方最大幅ＷＬがくびれ部１５と座部１３との境界に現れている。また、本実施の形態では、座部１３、くびれ部１５、口頸部１９の高さの比率が、４：１５：１４に形成されている（例えば内容物の充填容量が３００ｃｃの場合は、座部１３の高さが２０ｍｍ、くびれ部１５の高さが７５ｍｍ、口頸部１９の高さが７０ｍｍに形成される）。本実施の形態の容器１０は、ＢＭＩに基づく日本人の標準体型とされる成人（ＢＭＩ値２０〜２５）が、人差指から小指までを略接触させた部分と親指とで両側面を、人差指及び中指と親指とで両くびれ１６を挟むように把持したときに薬指及び小指が上方最大幅ＷＨ（容器１０を逆さにして把持した場合）又は下方最大幅ＷＨ（開口１８を上向きにして容易１０を把持した場合）に来るような大きさに形成されている。 The container 10 defines the horizontal surface of the top of the recess 15d as the boundary between the constricted portion 15 and the mouth-and-neck portion 19 (the recess 15d belongs to the constricted portion 15), and the height of the lowermost portion of the recess 15d. A horizontal plane slightly lower than the height (for example, 2 mm to 10 mm below) is defined as the boundary between the constricted portion 15 and the seat portion 13. In the present embodiment, the maximum downward width WL appears at the boundary between the constricted portion 15 and the seat portion 13. Moreover, in this Embodiment, the ratio of the height of the seat part 13, the constricted part 15, and the mouth-and-neck part 19 is formed in 4:15:14 (For example, when the filling capacity of the contents is 300 cc, The height of the seat portion 13 is 20 mm, the height of the constricted portion 15 is 75 mm, and the height of the mouth and neck portion 19 is 70 mm). The container 10 according to the present embodiment is configured so that an adult (BMI value 20 to 25), which is a Japanese standard figure based on BMI, has both sides of the index finger and the thumb between the index finger and the little finger. When holding the middle finger and the thumb so that the constriction 16 is sandwiched between them, the ring finger and the little finger have an upper maximum width WH (when the container 10 is held upside down) or a lower maximum width WH (the opening 18 faces upward to facilitate 10). It is formed in such a size as to come in the case of gripping).

以上で説明したような容器１０の形状とすることで、表面が濡れていて滑りやすい場合であっても落としにくく、取り扱いやすいものとなる。具体的に例示すると、くびれ１６が形成されているので把持したときに手の平になじみやすく、視力の弱い者が視覚に頼らずに触覚を頼りにして適切な位置で把持することができる。また、正面視において上方最大幅ＷＨよりも下方最大幅ＷＬが大きく形成されているので、容器１０を逆さにして把持した状態（図６参照）で滑ったときに、下方最大幅ＷＬが手に引っかかりやすく、より容器１０を落としにくくなる。また、下方最大幅ＷＬが大きく形成されていることにより、容器１０を水平面ＨＰに載置したときの安定感が増すこととなる。さらに、容器１０の正面及び背面に平面帯１５ｐｆ、１５ｐｂが形成されているので、容器１０を把持したときの手との接触面積を増加させて手と容器１０との摩擦力を増加させることができ落としにくくなると共に、内容物を出すために両平面帯１５ｐｆ、１５ｐｂを押圧する際の押圧力が外側に凸に形成されている場合よりも小さくて済む。また、平面帯１５ｐｆ、１５ｐｂが形成されていると、内容物を表示する表示ラベルを正面平面帯１５ｐｆ及び／又は背面平面帯１５ｐｂに貼付することで、斜め方向から見たときも表示ラベルを視認しやすくなる。 By adopting the shape of the container 10 as described above, even when the surface is wet and slippery, it is difficult to remove and easy to handle. Specifically, since the constriction 16 is formed, it is easy to adapt to the palm when grasped, and a person with weak visual acuity can rely on the sense of touch and grasp at an appropriate position without relying on vision. Further, since the lower maximum width WL is formed larger than the upper maximum width WH in a front view, the lower maximum width WL is in hand when the container 10 is slid in a gripped state (see FIG. 6). It is easy to get caught and it becomes more difficult to drop the container 10. Further, since the lower maximum width WL is formed larger, a sense of stability when the container 10 is placed on the horizontal plane HP is increased. Furthermore, since the flat bands 15pf and 15pb are formed on the front and back surfaces of the container 10, the contact area with the hand when the container 10 is gripped can be increased to increase the frictional force between the hand and the container 10. In addition to being difficult to drop off, the pressing force when pressing the two flat strips 15pf and 15pb in order to take out the contents can be smaller than in the case where the pressing force is formed outwardly. In addition, when the flat strips 15pf and 15pb are formed, the display label for displaying the contents is attached to the front flat strip 15pf and / or the back flat strip 15pb so that the display label can be viewed even when viewed from an oblique direction. It becomes easy to do.

なお、口頸部１９のくびれ部１５に近い部分の水平断面（図５（ａ）参照）が楕円形にに形成されているので、内容物の充填容量の減少を抑制することができる。また、座部１３の筒状部１２の水平断面が略六角形に形成されているので、くびれ部１５の正面平面帯１５ｐｆ及び背面平面帯１５ｐｂへのつながりをスムーズにできる。また、正面平面帯１５ｐｆ及び正面脇帯１５ｔｆを合わせた領域の両側及び上部に窪み１５ｄが形成されているので、水平断面が楕円形に形成された口頸胴部１７の下部と両平面帯１５ｐｆ、１５ｐｂとを区別してそれぞれの役割を効果的に発揮させることができる。 In addition, since the horizontal cross section (refer FIG. 5 (a)) of the part near the constriction part 15 of the mouth neck part 19 is formed in the ellipse, the reduction | decrease of the filling capacity | capacitance of the content can be suppressed. Moreover, since the horizontal cross section of the cylindrical part 12 of the seat part 13 is formed in the substantially hexagonal shape, the connection to the front plane belt | band | zone 15pf and back plane belt | band | zone 15pb of the constricted part 15 can be made smooth. Further, since the depressions 15d are formed on both sides and the upper part of the region including the front plane band 15pf and the front side band 15tf, the lower part of the mouth-and-cervical torso part 17 whose horizontal section is formed in an oval shape and both plane bands 15pf. , 15 pb can be distinguished from each other and each role can be effectively exhibited.

容器１０は、合成樹脂が複数層積層されて構成されている。容器１０は、典型的には多層ブロー成型により形成される。多層ブロー成型としては、特にはダイレクトブロー成型を好適に用いることができる。多層ブロー成型は、その金型から脱型したときに上述したような外形の容器１０となるような型の中に、筒状の形状で溶融状態のオレフィン系樹脂、ガスバリア性樹脂、接着性樹脂等の合成樹脂から選択した複数（同一種類を複数選択してもよい）を適切な順序で積層した上で型に押し込んだところへ空気を送り込み、最後に脱型することにより行われる。オレフィン系樹脂としては、特にはエチレン系樹脂、プロピレン系樹脂を好適に用いることができる。ガスバリア性樹脂としては、特にはエチレン−酢酸ビニル共重合体の部分鹸化物を好適に用いることができる。接着性樹脂としては、特にはエチレン−酢酸ビニル共重合体もしくはエチレン−アクリル酸エチル共重合体又はそのマレイン酸グラフト化物を好適に用いることができる。なお、最内面に滑剤を塗り込んでおくと、内容物を吐出しやすくなり好適である。滑剤としては、脂肪酸エステルを好適に用いることができる。 The container 10 is configured by stacking a plurality of synthetic resins. The container 10 is typically formed by multilayer blow molding. As the multilayer blow molding, in particular, direct blow molding can be suitably used. Multi-layer blow molding is a mold in which the container 10 has the outer shape as described above when it is removed from the mold, and is a molten olefin resin, gas barrier resin, adhesive resin in a cylindrical shape. A plurality of selected synthetic resins (or a plurality of the same type may be selected) are stacked in an appropriate order, air is fed into the mold and finally demolded. As the olefin resin, in particular, an ethylene resin or a propylene resin can be preferably used. As the gas barrier resin, in particular, a partially saponified product of ethylene-vinyl acetate copolymer can be suitably used. As the adhesive resin, in particular, an ethylene-vinyl acetate copolymer, an ethylene-ethyl acrylate copolymer, or a maleic acid grafted product thereof can be suitably used. Note that it is preferable to apply a lubricant to the innermost surface because the contents can be easily discharged. As the lubricant, a fatty acid ester can be suitably used.

容器１０は、くびれ部１５の正面平面帯１５ｐｆと背面平面帯１５ｐｂとを両者が近づくように押して変形させたときに弾性変形をするように、容器１０を形成する合成樹脂の積層体の厚さや材料の選択、積層順等を決定するとよい。ここでいう「弾性変形」は、押圧力を加えられて変形した容器１０が、押圧力を取り除くことにより原形に戻ることを意味する。このように構成されていることで、容器１０に充填した内容物を開口１８ｈから吐出するために正面平面帯１５ｐｆ及び背面平面帯１５ｐｂを押圧しても、押圧力を解除することで原形に戻るので、内容物の残量にかかわらず把持しやすい原形を維持することができる。本実施の形態では、積層体の厚さは、容器１０のくびれ部１５の積層体の厚さが概ね１００μｍ〜１０００μｍに形成されている。 The container 10 has a thickness of the laminated body of the synthetic resin forming the container 10 so as to be elastically deformed when the front plane band 15pf and the back plane band 15pb of the constricted portion 15 are pushed and deformed so as to approach each other. The selection of materials, the order of lamination, etc. may be determined. Here, “elastic deformation” means that the container 10 deformed by applying a pressing force returns to its original shape by removing the pressing force. By being configured in this way, even if the front plane belt 15pf and the back plane belt 15pb are pressed to discharge the contents filled in the container 10 from the opening 18h, the original shape is restored by releasing the pressing force. Therefore, it is possible to maintain an original shape that is easy to grip regardless of the remaining amount of contents. In the present embodiment, the thickness of the laminated body is such that the thickness of the laminated body of the constricted portion 15 of the container 10 is approximately 100 μm to 1000 μm.

以上で説明した図１等に示される容器１０の形状は、典型的には内容物が充填された使用態様における形状である。製造過程においては、以下のような形状であってもよい。
図７は、変形例に係る容器の部分正面図であり、（ａ）は第１の変形例に係る容器１０Ａの図、（ｂ）は第２の変形例に係る容器１０Ｂの図である。容器１０Ａは、将来開口部１８ｈとなるべき部分の上部に袋部２１が形成されている。袋部２１は、ブロー成型の過程で形成されるものであり（したがって、典型的には容器１０と同材質で形成される）、ブロー成型時は内部に空気を注入する針状の吹き込み口が差し込まれる部分である。袋部２１は、容器１０と一体に形成されるため、ブロー成型時の吹き込み口が外されると、容器１０Ａ内が略密封された状態となる。容器１０Ａは、内部が外気にさらされることを、内容物が充填される直前まで回避することが可能となるため、容器の製造場所と内容物の充填場所とが異なる場合の適用に好適であり、特に加熱殺菌が困難な冷やした状態で容器に充填される内容物のためのものとして好適である。容器１０Ａは、内容物が充填されるときに袋部２１が切り落とされ、容器１０側の切断面が開口１８ｈとなる。 The shape of the container 10 shown in FIG. 1 and the like described above is typically the shape in the usage mode in which the contents are filled. In the manufacturing process, the following shapes may be used.
FIG. 7 is a partial front view of a container according to a modified example, (a) is a diagram of a container 10A according to a first modified example, and (b) is a diagram of a container 10B according to a second modified example. In the container 10A, a bag portion 21 is formed on an upper portion of a portion that is to become an opening 18h in the future. The bag portion 21 is formed in the process of blow molding (thus, typically formed of the same material as the container 10), and has a needle-like blowing port for injecting air into the interior during blow molding. It is the part that is plugged in. Since the bag part 21 is formed integrally with the container 10, the inside of the container 10 </ b> A is substantially sealed when the blowing port at the time of blow molding is removed. The container 10A can be prevented from being exposed to the outside air until just before the contents are filled. Therefore, the container 10A is suitable for applications where the container manufacturing location and the content filling location are different. In particular, it is suitable for the contents filled in the container in a cooled state where heat sterilization is difficult. In the container 10A, the bag portion 21 is cut off when the contents are filled, and the cut surface on the container 10 side becomes an opening 18h.

他方、容器１０Ｂは、容器１０と別体の蓋２２が口頸螺部１８に螺着又は嵌着されている。蓋２２は、典型的には、硬質の合成樹脂で射出成型により形成される。容器１０Ｂは、蓋２２が取り付けられているので容器１０内が汚れるのを防ぐことができ、また、蓋２２が螺着又は嵌着されているので容器１０からはずしやすく、内容物を充填する際の手間を低減することができる。なお、図示は省略するが、容器１０（図１参照）の開口１８ｈに、内容物を吐出するための吐出口（開口１８ｈよりも小さい）が形成された中栓を取り付けてもよい。 On the other hand, the container 10 </ b> B has a lid 22 that is separate from the container 10 and is screwed or fitted to the mouth-and-neck screw 18. The lid 22 is typically made of a hard synthetic resin by injection molding. The container 10B can prevent the inside of the container 10 from becoming dirty because the lid 22 is attached. Also, since the lid 22 is screwed or fitted, the container 10B can be easily removed from the container 10 and is filled with contents. Can be reduced. In addition, although illustration is abbreviate | omitted, you may attach the inner stopper in which the discharge port (smaller than the opening 18h) for discharging the content was formed in the opening 18h of the container 10 (refer FIG. 1).

以上の説明では、くびれ１６付近の水平断面における全体的に六角形の各辺が略等しい長さに形成されているとした。しかしながら、両平面帯１５ｐｆ、１５ｐｂの幅を確保して、両平面帯１５ｐｆ、１５ｐｂを把持したときの手との接触面積を増加させると共に内容物を出すために両平面帯１５ｐｆ、１５ｐｂを押圧する際の押圧力を低減する観点から正面辺１５ｆｓ及び背面辺１５ｂｓがその他の合計４つの辺１５ｕｆ、１５ｕｂ、１５ｒｆ、１５ｒｂのそれぞれよりも長く形成されるようにしてもよい。逆に、容器１０の正面平面帯１５ｐｆ及び背面平面帯１５ｐｂを押圧して、弾性変形させたときの原形に戻る力（復元力）を高める観点から、また正面辺１５ｆｓ及び背面辺１５ｂｓにおける指掛かりをよくする観点から、正面辺１５ｆｓ及び背面辺１５ｂｓがその他の合計４つの辺１５ｕｆ、１５ｕｂ、１５ｒｆ、１５ｒｂのそれぞれよりも短く形成されるようにしてもよい。 In the above description, it is assumed that the hexagonal sides as a whole in the horizontal cross section near the constriction 16 are formed to have substantially the same length. However, the widths of the two flat bands 15pf and 15pb are secured to increase the contact area with the hand when the two flat bands 15pf and 15pb are gripped, and the two flat bands 15pf and 15pb are pressed to put out the contents. From the viewpoint of reducing the pressing force, the front side 15fs and the back side 15bs may be formed longer than each of the other four sides 15uf, 15ub, 15rf, 15rb. On the contrary, from the viewpoint of increasing the force (restoring force) for returning to the original shape when the front flat band 15pf and the back flat band 15pb of the container 10 are pressed and elastically deformed, the finger hooking on the front side 15fs and the back side 15bs is performed. From the viewpoint of improving, the front side 15fs and the back side 15bs may be formed shorter than each of the other four sides 15uf, 15ub, 15rf, and 15rb.

以上の説明では、上方最大幅ＷＨがくびれ部１５内に現れるとしたが、くびれ部１５と口頸部１９との境界に現れてもよく、口頸部１９に現れてもよい。また、下方最大幅ＷＬが、座部１３とくびれ部１５との境界に現れるとしたが、くびれ部１５内に現れてもよく、座部１３に現れてもよい。 In the above description, the upper maximum width WH appears in the constricted portion 15, but may appear at the boundary between the constricted portion 15 and the mouth and neck portion 19, or may appear in the mouth and neck portion 19. Further, although the lower maximum width WL appears at the boundary between the seat portion 13 and the constricted portion 15, it may appear within the constricted portion 15 or may appear at the seat portion 13.
