Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、角形プラスチックボトルに関し、特にプラスチックボトル胴部の構 造に関する。 The present invention relates to a rectangular plastic bottle, and more particularly to the structure of a plastic bottle body.

【0002】[0002]

【従来の技術】[Prior art]

従来、清涼飲料水等の容器として用いられている正多角形をなすプラスチック ボトルは高温充填によるボトル内の減圧の状態で移送保管されることが多い。ま た、プラスチックボトルに外圧がかかることがある。このため、ボトル胴部の中 央において、外圧又は減圧による変形が大きくなる。 Conventionally, regular polygonal plastic bottles that have been used as containers for soft drinks and the like are often transferred and stored under reduced pressure inside the bottles due to high temperature filling. Also, external pressure may be applied to the plastic bottle. Therefore, the deformation due to the external pressure or the reduced pressure is increased in the center of the bottle body.

【0003】 さらに、最近では、エコロジー対策の一環として製品の合成樹脂の使用量を減 らすためにボトル胴部が薄肉になってきている。このため、外圧又は減圧による ボトル胴部の変形が著しくなってきた。 そこで、ボトル胴部の変形の解決策として、図8に示すような断面が四角形状 をなすボトル胴部2の中間部付近のB−B´に図7に示すような1つの凹状の周 溝部4を形成し、ボトル胴部2の外圧等による変形を軽減するようにしていた。Further, in recent years, in order to reduce the amount of synthetic resin used in products as part of ecological measures, the bottle body has become thinner. For this reason, the deformation of the bottle body due to external pressure or pressure reduction has become remarkable. Therefore, as a solution to the deformation of the bottle body, one concave peripheral groove portion as shown in FIG. 7 is formed at BB ′ near the middle portion of the bottle body 2 having a rectangular cross section as shown in FIG. 4 is formed to reduce deformation of the bottle body 2 due to external pressure or the like.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、この周溝部4を形成したプラスチックボトルにあっては、次の ような問題があった。図9に示すように正四角形のボトル胴部2の一方の対角方 向の隅角部C1−C1´に外圧又は減圧が加わると、C1−C1´はC2−C2´に変 わる。However, the plastic bottle having the circumferential groove portion 4 has the following problems. 'When external pressure or vacuum is applied to, C 1 -C 1' positive corner one diagonal how direction of the rectangle of the bottle body portion 2 C 1 -C 1 as shown in FIG. 9 C 2 -C 2 It changes to ´.

【0005】 このとき、図10に示すように外圧均等によりC2−C2´はC1−C1´に対し て、−F°回転するように変形する。すなわち、その隅角部に対応する周溝部が 狭くなるよう変形する。 また、外圧等に伴って他方の対角方向の隅角部D1−D1´はD2−D2´に変わ る。このとき、図11に示すようにD2−D2´はD1−D1´に対して+F°回転 するように変形する。すなわち、その隅角部に対応する周溝部が広くなるよう変 形する。At this time, as shown in FIG. 10, C 2 -C 2 ′ is deformed by −F ° rotation with respect to C 1 -C 1 ′ due to the uniform external pressure. That is, the circumferential groove portion corresponding to the corner is deformed so as to become narrow. Further, the other corners D 1 -D 1 ′ in the diagonal direction change to D 2 -D 2 ′ due to external pressure or the like. At this time, as shown in FIG. 11, D 2 −D 2 ′ is deformed so as to rotate + F ° with respect to D 1 −D 1 ′. In other words, the peripheral groove corresponding to the corner is widened.

【0006】 このようなボトルの折れ曲がり変形のために、ボトルのキャップを開封したと きに充填物が飛び出したりする。また、ボトルを持ち上げたときにはボトルの変 形により内容積が減るため、充填物が飛び出してしまうことがしばしばあった。 この場合、ボトルの肉厚を厚くすれば、この問題は解決されるが、前述したよう にボトルのエコロジー対策に反する。Due to such bending and deformation of the bottle, the filling material pops out when the cap of the bottle is opened. Also, when the bottle is lifted, the filling volume often pops out because the internal volume decreases due to the deformation of the bottle. In this case, this problem can be solved by increasing the thickness of the bottle, but it is against the ecological measures for the bottle as described above.

【0007】 本考案の目的は、かかる従来の問題点を解決するためになされたもので、減圧 や外圧に対してボトルの隅角部の座屈強度を高めることのできるプラスチックボ トルを提供することにある。An object of the present invention is to solve the above-mentioned conventional problems, and to provide a plastic bottle capable of increasing the buckling strength of a corner portion of a bottle against reduced pressure or external pressure. Especially.

【0008】[0008]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、前記課題を解決するために、以下のような構成とした。本考案のプ ラスチックボトルは角筒形に形成されたボトル胴部2の側面部3に周溝部4を形 成している。この周溝部4は、ボトル胴部2の隅角部5に対応した部位に溝部を 埋めるリブ部6を有するよう構成した。 The present invention has the following configuration in order to solve the above problems. In the plastic bottle of the present invention, a peripheral groove portion 4 is formed on a side surface portion 3 of a bottle body portion 2 formed in a rectangular tube shape. The circumferential groove portion 4 is configured to have a rib portion 6 that fills the groove portion at a portion corresponding to the corner portion 5 of the bottle body portion 2.

【0009】 さらに、各々の隅角部に複数のリブ部6を設けるようにしてもよい。 この側面部3の周溝部4の筒軸方向の幅を隅角部5のリブ部6の筒軸方向の幅 よりも大きく形成するようにしてもよい。 前記周溝部4の断面形状としては、例えば、逆円曲面形状、波形、あるいは台 形等の半円筒状にすることができる。Further, a plurality of ribs 6 may be provided at each corner. The width of the circumferential groove portion 4 of the side surface portion 3 in the cylinder axis direction may be formed to be larger than the width of the rib portion 6 of the corner portion 5 in the cylinder axis direction. The cross-sectional shape of the circumferential groove portion 4 may be, for example, an inverted circular curved surface shape, a corrugated shape, or a semi-cylindrical shape such as a trapezoid.

【0010】[0010]

【作用】[Action]

隅角部5に対応した部位に溝部を埋めるリブ部6を形成したので、このリブ部 6の形状が外圧又は減圧に対して補強効果を呈する。このため、リブ部6を有す る隅角部5に外圧又は減圧が加わった場合であっても、各々の隅角部5が外圧等 によって変形されにくくなる。 Since the rib portion 6 that fills the groove portion is formed at the portion corresponding to the corner portion 5, the shape of the rib portion 6 has a reinforcing effect against external pressure or reduced pressure. Therefore, even when external pressure or reduced pressure is applied to the corner portion 5 having the rib portion 6, each corner portion 5 is less likely to be deformed by the external pressure or the like.

【0011】[0011]

【実施例】【Example】

以下、本考案のプラスチックボトルの具体的な実施例を詳細に説明する。 <実施例1> 図1に本考案のプラスチックボトルの実施例1の側面図を示す。まず、プラス チックボトルは、例えば、PET(ポリエチレンテレフタレート:ヤング率E= 350Kg/mm,ポアソン比ν=0.4,肉厚0.35mm均一)で形成されている。ボトル胴部 2が正四角柱状に形成されており、ボトル胴部2の側面部3の中央部付近には周 溝部4が形成されている。 Hereinafter, specific examples of the plastic bottle of the present invention will be described in detail. Example 1 FIG. 1 shows a side view of Example 1 of the plastic bottle of the present invention. First, the plastic bottle is formed of, for example, PET (polyethylene terephthalate: Young's modulus E = 350 Kg / mm, Poisson's ratio ν = 0.4, wall thickness 0.35 mm uniform). The bottle body 2 is formed in a regular square pole shape, and a peripheral groove portion 4 is formed near the center of the side surface portion 3 of the bottle body 2.

【0012】 ここでは、周溝部4の深さを例えば1.5mmとし、周溝部4の底部から胴部側面 に至る傾斜角度を45°とし、周溝部4の底部の幅を4mmとしている。 そして、この周溝部4は、ボトル胴部2の隅角部5に対応した部位に溝部を埋 めるリブ部6を有している。1つの隅角部5におけるリブ部6の詳細な構成を図 2に示す。このリブ部6は例えば前記PETで形成され、周溝部4の底部42を 挟んで上下の傾斜部41をつなぐよう構成されている。Here, the depth of the circumferential groove portion 4 is, for example, 1.5 mm, the inclination angle from the bottom portion of the circumferential groove portion 4 to the side surface of the body portion is 45 °, and the width of the bottom portion of the circumferential groove portion 4 is 4 mm. The peripheral groove portion 4 has a rib portion 6 that fills the groove portion at a portion corresponding to the corner portion 5 of the bottle body portion 2. A detailed configuration of the rib portion 6 in one corner portion 5 is shown in FIG. The rib portion 6 is formed of, for example, PET, and is configured to connect the upper and lower inclined portions 41 with the bottom portion 42 of the circumferential groove portion 4 interposed therebetween.

【0013】 図3にリブ部6の断面図を示す。このリブ部6の深さは溝部の深さに対してわ ずかながら浅くなっている。なお、リブ部6がリブ部6が側面部3の面位置まで 形成されているもよい。 例えば、図4に示す変形例では、傾斜部41及び底部42を有する周溝部4の 内、隅角部5の内の任意の長さQに対応する周溝部が除去されて構成される。こ の場合には、リブ部6が側面部3の面位置まで形成されているのと同じである。FIG. 3 shows a sectional view of the rib portion 6. The depth of the rib portion 6 is slightly shallower than the depth of the groove portion. The rib portion 6 may be formed up to the surface position of the side surface portion 3. For example, in the modified example shown in FIG. 4, the circumferential groove portion 4 having the inclined portion 41 and the bottom portion 42 and the circumferential groove portion corresponding to an arbitrary length Q of the corner portion 5 are removed. In this case, it is the same as the rib portion 6 is formed up to the surface position of the side surface portion 3.

【0014】 このようなプラスチックボトルにおいては、隅角部5に対応した部位に溝部を 埋めるリブ部6を形成したので、このリブ部6の形状が外圧又は減圧に対して補 強効果を呈するため、減圧や外圧に対して隅角部5の座屈強度を高めることがで きる。その結果、リブ部6を有する隅角部5に外圧又は減圧が加わった場合であ っても、各々の隅角部5が外圧等によって変形されにくくなる。In such a plastic bottle, since the rib portion 6 that fills the groove portion is formed in the portion corresponding to the corner portion 5, the shape of the rib portion 6 has a reinforcing effect against external pressure or reduced pressure. It is possible to increase the buckling strength of the corner portion 5 against the reduced pressure or the external pressure. As a result, even when external pressure or reduced pressure is applied to the corner portion 5 having the rib portion 6, each corner portion 5 is less likely to be deformed by the external pressure or the like.

【0015】 従って、薄い肉厚のボトルであっても、ボトルが折れ曲がり変形しないため、 ボトルのキャップを開封したときに充填物が飛び出したりするなどの問題がなく なる。 <実施例2> 次に、本考案の実施例2について説明する。図5に実施例2のプラスチックボ トルの斜視図を示す。図6に実施例2の側面図を示す。なお、図5及び図6にお いては、周溝部の周辺の構成を示しており、図に示す以外の部分の構成は実施例 1の構成と同一である。図5に示すように夫々の隅角部5にはリブ部6が形成さ れており、隅角部5相互間の側面部3には周溝部4aが形成されている。Therefore, even if the bottle has a small thickness, the bottle is not bent and deformed, so that there is no problem that the filling material pops out when the cap of the bottle is opened. <Second Embodiment> Next, a second embodiment of the present invention will be described. FIG. 5 shows a perspective view of the plastic bottle of the second embodiment. FIG. 6 shows a side view of the second embodiment. 5 and 6, the configuration around the peripheral groove portion is shown, and the configuration of the parts other than those shown in the drawings is the same as that of the first embodiment. As shown in FIG. 5, rib portions 6 are formed in the respective corner portions 5, and a peripheral groove portion 4a is formed in the side surface portion 3 between the corner portions 5.

【0016】 この周溝部4aは、溝部の筒軸方向の幅a,bが隅角部5の幅cから側面部3 の中間に向かって徐々に大きくなった後に一定値になっている。ここで、幅aは 側面部3の面位置における幅であり、幅bは底部の幅である。すなわち、側面部 3の周溝部4aの筒軸方向の幅a,bが隅角部5のリブ部6の筒軸方向の幅cよ りも大きく形成されている。The circumferential groove portion 4a has a constant value after the widths a and b of the groove portion in the cylinder axis direction gradually increase from the width c of the corner portion 5 toward the middle of the side surface portion 3. Here, the width a is the width at the surface position of the side surface portion 3, and the width b is the width of the bottom portion. That is, the widths a and b of the circumferential groove portion 4a of the side surface portion 3 in the cylinder axis direction are formed to be larger than the width c of the rib portion 6 of the corner portion 5 in the cylinder axis direction.

【0017】 このようなプラスチックボトルにおいては、側面部3の周溝部4aの筒軸方向 の幅a,bが隅角部5のリブ部6の筒軸方向の幅cよりも大きく形成されている ので、ボトル胴部2の全周において外圧又は減圧に対する強度が均一化する。こ のため、減圧や外圧に対して隅角部5の強度を高めることができる。また、隅角 部5にリブ部6が設けられているから、実施例1の効果にさらに周溝部4aによ る効果が加わり、効果が大となる。In such a plastic bottle, the widths a and b of the circumferential groove portion 4a of the side surface portion 3 in the cylinder axis direction are formed larger than the width c of the rib portion 6 of the corner portion 5 in the cylinder axis direction. Therefore, the strength against the external pressure or the reduced pressure is made uniform over the entire circumference of the bottle body 2. For this reason, the strength of the corner portion 5 can be increased against the reduced pressure and the external pressure. Further, since the rib portion 6 is provided in the corner portion 5, the effect of the circumferential groove portion 4a is further added to the effect of the first embodiment, and the effect becomes large.

【0018】 なお、実施例1及び実施例2では、ボトル胴部2の形状として四角形状として 説明したが、例えば6角形状あるいはその他の角形状であっても、本考案は適用 可能である。 さらに、実施例1及び実施例2では、夫々の隅角部5に1つのリブ部6を設け るようにしたが、例えば夫々の隅角部5に2つ以上のリブ部6を設けるようにし てもよい。In the first and second embodiments, the shape of the bottle body 2 is described as a quadrangular shape, but the present invention can be applied to, for example, a hexagonal shape or another rectangular shape. Further, in the first and second embodiments, one rib 6 is provided in each corner 5, but, for example, two or more ribs 6 are provided in each corner 5. May be.

【0019】[0019]

【考案の効果】[Effect of device]

本考案によれば、隅角部5に対応した部位に溝部を埋めるリブ部6を形成した ので、リブ部6の形状が外圧等に補強効果を呈する。このため、リブ部6を有す る隅角部5に外圧又は減圧が加わった場合であっても、対角方向での外圧等によ りボトル容器が変形されにくくなる。 According to the present invention, since the rib portion 6 that fills the groove portion is formed in the portion corresponding to the corner portion 5, the shape of the rib portion 6 has a reinforcing effect against external pressure and the like. Therefore, even when external pressure or reduced pressure is applied to the corner portion 5 having the rib portion 6, the bottle container is less likely to be deformed by the external pressure in the diagonal direction or the like.

【0020】 従って、薄い肉厚のボトルであっても、ボトルが折れ曲がり変形しないため、 ボトルのキャップを開封したときに充填物が飛び出したりするなどの問題がなく なる。Therefore, even if the bottle has a small thickness, the bottle is not bent and deformed, so that there is no problem that the filling material pops out when the cap of the bottle is opened.
