JP 2005-8153 A JP-A-8-301253

ところが、この角型ボトルでは、パネル面部における前記境界部分に大きな圧縮力が作用すると、この圧縮力によってパネル面部が大きくへこみ、これに伴いこのパネル面部に連なる稜線も折り曲げられ、さらにこの稜線に連なるコーナ面部までもへこむことがある。この場合、前記の変形が弾性力によって復元せずへこんだ状態に維持され、この状態で店頭に並べられて需要者の購買意欲を喪失させるおそれがあった。なお、前記へこみがパネル面部内に留まれば、通常このへこみは弾性力により復元することになる。   However, in this square bottle, when a large compressive force acts on the boundary portion in the panel surface portion, the panel surface portion is greatly dented by the compressive force, and accordingly, the ridge line connected to the panel surface portion is also bent and further connected to the ridge line. The corner surface may also be dented. In this case, the deformation is not restored by the elastic force, but is maintained in a depressed state, and in this state, there is a possibility that the customer's willingness to purchase is lost. In addition, if the said dent stays in a panel surface part, this dent will be normally decompress | restored by elastic force.

本発明は、このような事情を考慮してなされたもので、パネル面部に生じたへこみが、このパネル面部に隣接するコーナ面部に伝播するのを防ぐことができる角型ボトルを提供することを目的とする。   The present invention has been made in consideration of such circumstances, and provides a square bottle capable of preventing a dent generated in a panel surface portion from propagating to a corner surface portion adjacent to the panel surface portion. Objective.

上記課題を解決して、このような目的を達成するために、本発明の角型ボトルは、胴部と、この胴部のボトル軸線方向下端に設けられた底部と、胴部の上端部に設けられた肩部と、この肩部の上端に設けられた口部とを備え、底部から肩部にわたった部分は、パネル面部とコーナ面部とが稜線をなしてボトル軸線回りに交互に連設された合成樹脂製の角型ボトルであって、コーナ面部において胴部と肩部との境界部分、および胴部と底部との境界部分の少なくとも一方には、凹部が形成されていることを特徴とする。   In order to solve the above-mentioned problems and achieve such an object, the square bottle of the present invention has a barrel, a bottom provided at the lower end in the bottle axial direction of the barrel, and an upper end of the barrel. It has a shoulder part provided and a mouth part provided at the upper end of the shoulder part. In the part extending from the bottom part to the shoulder part, the panel surface part and the corner surface part form a ridge line and are alternately connected around the bottle axis. It is a square bottle made of synthetic resin, and a recess is formed in at least one of a boundary portion between the trunk portion and the shoulder portion and a boundary portion between the trunk portion and the bottom portion in the corner surface portion. Features.

この発明では、コーナ面部において前記各境界部分の少なくとも一方に、凹部が形成されているので、この境界部分における凹部と稜線との間の部分が、この稜線に連なるパネル面部に生ずる圧縮変形（へこみ）に対してリブとして作用することになる。したがって、パネル面部における前記各境界部分の少なくとも一方に大きな圧縮力が作用し、この部分が大きくへこんでも、この変形に伴って稜線が折り曲げられるのを防ぐことが可能になり、この変形をコーナ面部に伝播させずこのパネル面部内に留めることができる。   In the present invention, since the concave portion is formed in at least one of the boundary portions in the corner surface portion, the portion between the concave portion and the ridge line in the boundary portion is compressed and deformed (dented) generated in the panel surface portion connected to the ridge line. ) To act as a rib. Therefore, even if a large compressive force acts on at least one of the boundary portions in the panel surface portion and this portion is greatly dented, it becomes possible to prevent the ridge line from being bent along with this deformation, and this deformation is prevented from being applied to the corner surface portion. It can be kept in the panel surface without propagating to the panel.

ここで、前記凹部は、前記稜線が延びる方向に延在した縦溝を備えてもよい。
この場合、凹部が縦溝を備えているので、前述した凹部と稜線との間の部分を、この境界部分における稜線が延びる方向の略全域にわたって前記リブとして作用させることが可能になり、前記の作用効果が確実に奏効されることになる。 Here, the concave portion may include a longitudinal groove extending in a direction in which the ridge line extends.
In this case, since the concave portion includes the vertical groove, the portion between the concave portion and the ridge line described above can be caused to act as the rib over substantially the entire region in the direction in which the ridge line extends in the boundary portion. The effect is surely achieved.

また、胴部と肩部との境界部分におけるコーナ面部は、この角型ボトルの内側に向けて肩部よりも小さく傾斜してボトル軸線方向に延在したテーパ面部とされてもよい。   Further, the corner surface portion at the boundary portion between the body portion and the shoulder portion may be a tapered surface portion that is inclined smaller than the shoulder portion toward the inside of the square bottle and extends in the bottle axis direction.

この場合、胴部と肩部とがテーパ面部を介して連結されることによって、胴部と肩部とでボトル軸線方向に対する傾斜角度が急激に変化するのを抑えることが可能になり、このボトルの座屈強度を向上させることができる。   In this case, by connecting the body part and the shoulder part via the tapered surface part, it is possible to suppress a sudden change in the inclination angle with respect to the bottle axis direction between the body part and the shoulder part. The buckling strength of can be improved.

さらに、前記凹部の外縁は、前記テーパ面部の外縁に沿って延びていてもよい。
この場合、前記テーパ面部における凹部と稜線との間の部分を前記リブとして作用させることが可能になることに加え、このテーパ面部自体の、ボトル内側に向けた圧縮力に対する剛性を向上させることが可能になる。したがって、前記稜線が折り曲げられるのを防ぐことが可能になることと相俟って、複数の角型ボトルが連立状態で搬送等され、隣合う角型ボトル同士で、前記各境界部分が互いに接触し合い、これらの各境界部分にボトルの内側に向けて大きな圧縮力が作用しても、この部分に永久変形が生ずるのを確実に防ぐことができる。 Furthermore, the outer edge of the concave portion may extend along the outer edge of the tapered surface portion.
In this case, in addition to allowing the portion between the concave portion and the ridge line in the tapered surface portion to act as the rib, it is possible to improve the rigidity of the tapered surface portion itself against the compressive force toward the inside of the bottle. It becomes possible. Accordingly, in combination with the fact that it is possible to prevent the ridgeline from being bent, a plurality of square bottles are conveyed in a continuous state, and the respective boundary portions are in contact with each other between adjacent square bottles. However, even if a large compressive force is applied to each boundary portion toward the inside of the bottle, it is possible to reliably prevent permanent deformation of the portion.

さらにまた、前記凹部は環状溝とされてもよい。
この場合、前記の作用効果が確実に奏効されることになる。 Furthermore, the recess may be an annular groove.
In this case, the above-described effects are surely achieved.

この発明に係る角型ボトルによれば、パネル面部に生じたへこみが、このパネル面部に隣接するコーナ面部に伝播するのを防ぐことができる。   According to the square bottle according to the present invention, it is possible to prevent the dent generated in the panel surface portion from propagating to the corner surface portion adjacent to the panel surface portion.

以下、図面を参照し、この発明の実施の形態について説明する。本実施形態に係る角型ボトル１０は、胴部１１と、この胴部１１のボトル軸線Ｏ方向下端に設けられた底部１２と、胴部１１の上端部に設けられた肩部１３と、この肩部１３の上端に設けられた口部１４とが、例えばポリエチレンテレフタレートやポリプロピレン等の合成樹脂により一体的に形成されている。なお、この角型ボトル１０は例えば２軸延伸ブロー成形により形成することができる。   Embodiments of the present invention will be described below with reference to the drawings. The square bottle 10 according to the present embodiment includes a body portion 11, a bottom portion 12 provided at the lower end of the body portion 11 in the bottle axis O direction, a shoulder portion 13 provided at the upper end portion of the body portion 11, A mouth portion 14 provided at the upper end of the shoulder portion 13 is integrally formed of a synthetic resin such as polyethylene terephthalate or polypropylene. The square bottle 10 can be formed by, for example, biaxial stretch blow molding.

そして、底部１２から肩部１３にわたった部分は、パネル面部１５と、このパネル面部１５の幅、つまりボトル軸線Ｏに直交する水平方向の大きさより幅の狭いコーナー面部１６とが稜線１７をなしてボトル軸線Ｏ回りに交互に連設されている。すなわち、このボトル１０は上面視および底面視が図３および図４に示されるような多角形状とされている。なお、図１から図４に示す斜線部分はパネル面部１５を示している。   A portion extending from the bottom portion 12 to the shoulder portion 13 includes a panel surface portion 15 and a corner surface portion 16 having a width smaller than the width of the panel surface portion 15, that is, the horizontal direction orthogonal to the bottle axis O. Are alternately arranged around the bottle axis O. In other words, the bottle 10 has a polygonal shape as shown in FIGS. 3 and 4 in a top view and a bottom view. The hatched portion shown in FIGS. 1 to 4 indicates the panel surface portion 15.

本実施形態では、パネル面部１５およびコーナ面部１６はそれぞれ４つ備えられ、パネル面部１５は、第１パネル面部１５ａ、およびこの第１パネル面部１５ａより幅狭の第２パネル面部１５ｂをそれぞれ２つずつ備えている。そして、２つの第１パネル面部１５ａ、１５ａがボトル軸線Ｏを挟んで対向して配置されるとともに、２つの第２パネル面部１５ｂ、１５ｂもボトル軸線Ｏを挟んで対向して配置されている。なお、コーナー面部１６は４つとも全て、第２パネル面部１５ｂより幅の狭い同等の幅とされている。   In the present embodiment, four panel surface portions 15 and four corner surface portions 16 are provided. The panel surface portion 15 includes a first panel surface portion 15a and two second panel surface portions 15b each having a narrower width than the first panel surface portion 15a. It has one by one. The two first panel surface portions 15a and 15a are disposed to face each other with the bottle axis line O interposed therebetween, and the two second panel surface portions 15b and 15b are also disposed to face each other with the bottle axis line O interposed therebetween. Note that all four corner surface portions 16 have the same width that is narrower than the second panel surface portion 15b.

ここで、胴部１１のボトル軸線Ｏ方向中央部には、その全周にわたって延在する環状凹リブ１１ａが形成されている。そして、胴部１１における前記各パネル面部１５には、環状凹リブ１１ａを挟んだボトル軸線Ｏ方向上部および下部にそれぞれ、前記水平方向に延びる複数の横リブ１５ｃがボトル軸線Ｏ方向に所定の間隔をあけて複数形成されている。   Here, an annular concave rib 11a extending over the entire circumference is formed in the central portion of the body portion 11 in the bottle axis O direction. Each panel surface portion 15 in the body portion 11 has a plurality of horizontal ribs 15c extending in the horizontal direction at a predetermined interval in the bottle axis O direction at the upper and lower portions in the bottle axis O direction with the annular concave rib 11a interposed therebetween. A plurality are formed with a gap.

そして、本実施形態では、コーナ面部１６において胴部１１と肩部１３との境界部分は、この角型ボトル１０の内側に向けて肩部１３よりも小さく傾斜してボトル軸線Ｏ方向に延在した第１テーパ面部１６ａとされている。
また、コーナ面部１６において胴部１１と底部１２との境界部分は、この角型ボトル１０の接地面１２ａの外周縁からボトル軸線Ｏ方向上方に向かうに従い漸次拡径された第２テーパ面部１６ｂとされている。 And in this embodiment, the boundary part of the trunk | drum 11 and the shoulder part 13 in the corner surface part 16 inclines smaller than the shoulder part 13 toward the inner side of this square bottle 10, and extends in the bottle axis O direction. The first tapered surface portion 16a.
Further, in the corner surface portion 16, the boundary portion between the body portion 11 and the bottom portion 12 has a second tapered surface portion 16 b that is gradually enlarged in diameter from the outer peripheral edge of the ground contact surface 12 a of the square bottle 10 toward the bottle axis O direction. Has been.

そして、本実施形態では、第１テーパ面部１６ａおよび第２テーパ面部１６ｂのうち少なくとも一方に、角型ボトル１０の内側にへこむ凹部１８が形成されている。図示の例では、凹部１８は４つの第１テーパ面部１６ａ全てに形成されている。この凹部１８は、その外周縁が、第１テーパ面部１６ａの外縁に沿って延在するように、一本の溝が環状につながった環状溝とされている。また、この凹部１８の平面視は、図５に示されるように、第１テーパ面部１６ａの外形形状と略同形状とされ、かつこの第１テーパ面部１６ａの外縁よりも内側に配置されている。さらに、凹部１８は、稜線１７上には位置されておらず、第１テーパ面部１６ａにおける凹部１８と稜線１７との間は、これら１８、１７の間に隙間が設けられて平滑面部１６ｃとされている。   And in this embodiment, the recessed part 18 dented inside the square bottle 10 is formed in at least one among the 1st taper surface part 16a and the 2nd taper surface part 16b. In the example shown in the drawing, the recess 18 is formed in all four first tapered surface portions 16a. The recess 18 is an annular groove in which one groove is annularly connected so that the outer peripheral edge thereof extends along the outer edge of the first tapered surface portion 16a. Further, as shown in FIG. 5, the plan view of the concave portion 18 is substantially the same as the outer shape of the first tapered surface portion 16 a and is disposed on the inner side of the outer edge of the first tapered surface portion 16 a. . Further, the concave portion 18 is not positioned on the ridge line 17, and a gap is provided between the concave portion 18 and the ridge line 17 in the first tapered surface portion 16a to form the smooth surface portion 16c. ing.

なお、本実施形態では、凹部１８は、その平面視が、前記水平方向に延びる２本の横溝１８ａと、ボトル軸線Ｏ方向に延びる２本の縦溝１８ｂとにより構成され、これら１８ａ、１８ｂが連続的につながった平面視矩形状の環状溝とされている。縦溝１８ｂ、１８ｂはそれぞれ、隣接する稜線１７が延びる方向に延在している。なお、凹部１８は、横溝１８ａおよび縦溝１８ｂの別を問わず、その全周にわたって略同じ幅、かつ略同じ深さとされて形成されている。   In the present embodiment, the concave portion 18 is constituted by two horizontal grooves 18a extending in the horizontal direction and two vertical grooves 18b extending in the bottle axis O direction in plan view. It is an annular groove having a rectangular shape in plan view that is continuously connected. Each of the vertical grooves 18b and 18b extends in a direction in which the adjacent ridge line 17 extends. In addition, the recessed part 18 is made into the substantially same width and the substantially same depth over the perimeter regardless of the distinction of the horizontal groove 18a and the vertical groove 18b.

以上説明したように本実施形態に係る角型ボトル１０によれば、第１テーパ面部１６ａに凹部１８が形成されているので、第１テーパ面部１６ａにおける凹部１８と稜線１７との間の平滑面部１６ｃが、この稜線１７に連なるパネル面部１５に生ずる圧縮変形（へこみ）に対してリブとして作用することになる。したがって、パネル面部１５における肩部１３と胴部１１との境界部分に大きな圧縮力が作用し、この部分が大きくへこんでも、この変形に伴って稜線１７が折り曲げられるのを防ぐことが可能になり、この変形をコーナ面部１６に伝播させずこのパネル面部１５内に留めることができる。   As described above, according to the square bottle 10 according to the present embodiment, since the concave portion 18 is formed in the first tapered surface portion 16a, the smooth surface portion between the concave portion 18 and the ridge line 17 in the first tapered surface portion 16a. 16 c acts as a rib against compressive deformation (dent) generated in the panel surface portion 15 connected to the ridge line 17. Therefore, even if a large compressive force acts on the boundary portion between the shoulder portion 13 and the trunk portion 11 in the panel surface portion 15 and this portion is greatly dented, it is possible to prevent the ridge line 17 from being bent along with this deformation. The deformation can be retained in the panel surface portion 15 without propagating to the corner surface portion 16.

また、凹部１８は、稜線１７が延びる方向に延在した縦溝１８ｂを備えているので、第１テーパ面部１６ａにおける凹部１８と稜線１７との間の平滑面部１６ｃを、この第１テーパ面部１６ａにおいて稜線１７が延びる方向の略全域にわたって前記リブとして作用させることが可能になり、前記の作用効果が確実に奏効されることになる。   Moreover, since the recessed part 18 is equipped with the vertical groove 18b extended in the direction where the ridgeline 17 is extended, the smooth surface part 16c between the recessed part 18 and the ridgeline 17 in the 1st taper surface part 16a is made into this 1st taper surface part 16a. In this case, it is possible to cause the ribs to act over substantially the entire region in the direction in which the ridge line 17 extends, so that the above-described effects can be reliably achieved.

さらに、コーナ面部１６において胴部１１と肩部１３との境界部分は、この角型ボトル１０の内側に向けて肩部１３よりも小さく傾斜してボトル軸線Ｏ方向に延在した第１テーパ面部１６ａとされ、この第１テーパ面部１６ａを介して胴部１１と肩部１３とが連結されているので、胴部１１と肩部１３とでボトル軸線Ｏに対する傾斜角度が急激に変化するのを抑えることが可能になり、このボトル１０の座屈強度を向上させることができる。   Furthermore, the first taper surface portion in which the boundary portion between the body portion 11 and the shoulder portion 13 in the corner surface portion 16 inclines smaller than the shoulder portion 13 toward the inside of the square bottle 10 and extends in the bottle axis O direction. Since the body 11 and the shoulder 13 are connected via the first tapered surface portion 16a, the inclination angle of the body 11 and the shoulder 13 with respect to the bottle axis O changes rapidly. Thus, the buckling strength of the bottle 10 can be improved.

さらに、凹部１８は、第１テーパ面部１６ａの外縁に沿って延びる環状溝とされているので、第１テーパ面部１６ａにおける凹部１８と稜線１７との間の平滑面部１６ｃを前記リブとして作用させることが可能になることに加え、第１テーパ面部１６ａ自体の、ボトル１０の内側に向けた圧縮力に対する剛性を向上させることが可能になる。
したがって、前述のように稜線１７が折り曲げられるのを防ぐことが可能になることと相俟って、複数の角型ボトル１０が連立状態で搬送等され、隣合う角型ボトル１０同士で、胴部１１と肩部１３との境界部分にボトル１０の内側に向けて大きな圧縮力が作用しても、この部分に永久変形が生ずるのを確実に防ぐことができる。 Furthermore, since the concave portion 18 is an annular groove extending along the outer edge of the first tapered surface portion 16a, the smooth surface portion 16c between the concave portion 18 and the ridge line 17 in the first tapered surface portion 16a acts as the rib. In addition to the above, it is possible to improve the rigidity of the first tapered surface portion 16a itself against the compressive force toward the inside of the bottle 10.
Therefore, coupled with the fact that it is possible to prevent the ridge line 17 from being bent as described above, a plurality of square bottles 10 are transported in a continuous state, and the adjacent square bottles 10 are connected to each other. Even when a large compressive force acts on the boundary portion between the portion 11 and the shoulder portion 13 toward the inside of the bottle 10, it is possible to reliably prevent permanent deformation from occurring in this portion.

なお、本発明の技術的範囲は前記実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば、前記実施形態では、コーナ面部１６において、胴部１１と肩部１３との境界部分が第１テーパ面部１６ａとされ、胴部１１と底部１２との境界部分が第２テーパ面部１６ｂとされた構成を示したが、これに代えて、これらの第１、第２テーパ面部１６ａ、１６ｂを有さず、胴部１１と肩部１３とが連結されるとともに、胴部１１と底部１２とが連結されて、コーナ面部１６において胴部１１と肩部１３との境界部分、および胴部１１と底部１２との境界部分の少なくとも一方に凹部を形成するようにしてもよい。 The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the embodiment, in the corner surface portion 16, the boundary portion between the body portion 11 and the shoulder portion 13 is the first tapered surface portion 16a, and the boundary portion between the body portion 11 and the bottom portion 12 is the second tapered surface portion 16b. Instead of this, instead of having the first and second tapered surface portions 16a and 16b, the trunk portion 11 and the shoulder portion 13 are connected, and the trunk portion 11 and the bottom portion 12 are connected. Are connected to each other so that a concave portion may be formed in at least one of the boundary portion between the trunk portion 11 and the shoulder portion 13 and the boundary portion between the trunk portion 11 and the bottom portion 12 in the corner surface portion 16.

また、前記実施形態では、第１テーパ面部１６ａにのみ凹部１８を形成したが、これに代えて、第２テーパ面部１６ｂにも凹部１８を形成してもよく、あるいは第２テーパ面部１６ｂにのみ凹部１８を形成してもよい。

Alternatively, the concave portion 18 may be formed on the second tapered surface portion 16b, or only on the second tapered surface portion 16b. The recess 18 may be formed.
Furthermore, in the said embodiment, although the said annular groove was shown as the recessed part 18, you may make it dent the whole including the part enclosed by the horizontal groove 18a and the vertical groove 18b instead, for example, Further, although the concave portion 18 having a rectangular shape in plan view is shown, for example, a concave portion having a circular shape or an elliptical shape in a plan view may be adopted, and the concave portion may be formed by one or a plurality of grooves. For example, only one of the horizontal groove 18a and the vertical groove 18b may be formed as the recess, and only one of the horizontal groove 18a or the vertical groove 18b may be formed. Furthermore, these 18a, You may make it form 18b one by one.

また、前記実施形態では、凹部として、その外縁が第１テーパ面部１６ａの外縁に沿うような環状溝を示したが、これに代えて、第１テーパ面部１６ａにおいて、第１、第２パネル面部１５ａ、１５ｂのうち大きく圧縮変形し易い、幅の広い第１パネル面部１５ａ側の部分にのみ凹部を形成するようにしてもよい。
さらに、パネル面部１５およびコーナ面部１６の各個数は前記実施形態のものに限られるものではない。
また、前記実施形態では、凹部１８として、横溝１８ａおよび縦溝１８ｂの別を問わず、その全周にわたって略同じ幅、かつ略同じ深さとされた構成を示したが、これに代えて、例えば幅および深さの少なくとも一方を横溝１８ａと縦溝１８ｂとで異ならせるようにしてもよい。 Further, in the above-described embodiment, as the concave portion, the annular groove whose outer edge is along the outer edge of the first tapered surface portion 16a is shown, but instead, in the first tapered surface portion 16a, the first and second panel surface portions. You may make it form a recessed part only in the part by the side of the 1st panel surface part 15a with a large width which is easy to compressively deform among 15a, 15b.
Furthermore, the number of each of the panel surface part 15 and the corner surface part 16 is not restricted to the thing of the said embodiment.
