本考案は、調味料、油類等の液体内容物を収納する二軸延伸ポリエチレンテレ フタレート製ボトルの改良に関する。 The present invention relates to an improvement in a biaxially stretched polyethylene terephthalate bottle for containing liquid contents such as seasonings and oils.
【0002】[0002]
従来、実開昭61−107711号公報に見られるような二軸延伸ポリエチレ ンテレフタレート製ボトルが知られている。 Conventionally, bottles made of biaxially stretched polyethylene terephthalate as disclosed in Japanese Utility Model Publication No. 61-107711 are known.
【0003】 この種のボトル30は、図3に示すように、口部31と、胴部32と、底部3 3とから成り、該ボトル30の内部に液体内容物を充填した後、前記口部31に 図示しないキャップを冠着して密封する。As shown in FIG. 3, this type of bottle 30 is composed of a mouth portion 31, a body portion 32, and a bottom portion 33, and after filling the inside of the bottle 30 with a liquid content, A cap (not shown) is attached to the portion 31 to seal it.
【0004】 また、前記胴部32の上半部32aには、その全周に水平に複数の水平凹条部 34が間隔を存して形成されており、該胴部32の中央部32bには前記水平凹 条部34よりも深溝形状の括れ部35が形成されている。更に、前記胴部32の 下半部32cには、その全周に該ボトル30の軸線yに対して30°の角度で傾 斜する複数の傾斜凹条部36が間隔を存して形成されている。Further, a plurality of horizontal recessed portions 34 are horizontally formed on the upper half portion 32a of the body portion 32 at intervals along the entire circumference thereof, and are formed in the central portion 32b of the body portion 32. Is formed with a constricted portion 35 having a deeper groove shape than the horizontal recessed portion 34. Further, the lower half portion 32c of the body portion 32 is formed with a plurality of inclined groove portions 36 which are inclined at an angle of 30 ° with respect to the axis y of the bottle 30 at the entire circumference thereof. ing.
【0005】 ところで、該ボトル30は、強度、透明性、ガスバリヤ性に優れており、比較 的軽量であることから、炭酸飲料等の容器として使用されていたが、近年におい ては、調味料、油類等の内容物を70℃前後に加熱した状態で充填する所謂ホッ トパック用容器としても使用されている。By the way, since the bottle 30 is excellent in strength, transparency and gas barrier property and is comparatively light in weight, it has been used as a container for carbonated drinks or the like. It is also used as a so-called hot pack container for filling contents such as oils in a state of being heated to around 70 ° C.
【0006】 前記のような構成によるボトル30は、ホットパック用の容器として好適であ る。即ち、該ボトル30内に密封した内容物の温度の低下によってボトル30の 内圧が減少する。このとき、前記各傾斜凹条部36が胴部32の下半部32cの 均一なねじれ変形を促してボトル30の容積を減少させ、ボトル30の内圧の低 下を吸収する。これにより、該ボトル30は、その内部に密封した内容物が温度 の低下によって収縮しても、前記各傾斜凹条部36によって内圧の低下を均一に 吸収してボトル30の減圧変形を比較的小とし、ボトル30が部分的に大きく変 形して美観を損ねることを防止することができる。The bottle 30 having the above structure is suitable as a container for hot packs. That is, the internal pressure of the bottle 30 decreases due to the decrease in the temperature of the contents sealed in the bottle 30. At this time, each of the inclined groove portions 36 promotes uniform torsional deformation of the lower half portion 32c of the body portion 32, reduces the volume of the bottle 30, and absorbs the decrease in the internal pressure of the bottle 30. As a result, even if the contents hermetically sealed inside the bottle 30 contract due to a decrease in temperature, the inclined concave streaks 36 uniformly absorb the decrease in internal pressure and relatively reduce the pressure reduction deformation of the bottle 30. It is possible to prevent the bottle 30 from being deformed to a large extent and spoiling its aesthetic appearance by making it small.
【0007】 しかし、前記ボトル30は、ホットパック用容器として好適である反面、該ボ トル30に加えられる垂直荷重によって前記各傾斜凹条部36が変形し易く、胴 部32の下半部32cの座屈強度が低いといった不都合がある。However, while the bottle 30 is suitable as a container for hot packs, the inclined groove portions 36 are easily deformed by the vertical load applied to the bottle 30, and the lower half portion 32c of the body portion 32 is easily deformed. However, the buckling strength is low.
【0008】 そこで、ボトル30の肉厚を厚く形成して前記各傾斜凹条部36での座屈強度 を向上させることが考えられるが、肉厚の比較的厚いボトル30を形成するため にはその材料であるポリエチレンテレフタレートの材料コストが増加する不都合 がある。Therefore, it is conceivable to increase the thickness of the bottle 30 to increase the buckling strength of the inclined groove portions 36. However, in order to form the bottle 30 having a relatively large thickness, There is a disadvantage that the material cost of the material, polyethylene terephthalate, increases.
【0009】[0009]
本考案は、かかる不都合を解消して、材料コストを増加させることなく、減圧 変形を小とし且つ座屈強度の高い形状の二軸延伸ポリエチレンテレフタレート製 ボトルを提供することを目的とする。 An object of the present invention is to provide a bottle made of biaxially stretched polyethylene terephthalate, which eliminates such inconvenience, reduces deformation under reduced pressure, and has high buckling strength without increasing material cost.
【0010】[0010]
本発明者は、ボトルの胴部全周に形成する複数の凹条部のボトルの軸線に対す る傾斜角度について検討した結果、該凹条部がボトルの軸線に対して31.5° 未満の角度で傾斜する場合には、ボトル内部の減圧に伴う変形は小である反面、 座屈強度が低下し、該凹条部がボトルの軸線に対して38.5°を越える角度で 傾斜する場合には、座屈強度が向上する反面、ボトル内部の減圧に伴う変形は大 となることを知見した。 The present inventor has examined the inclination angles of a plurality of concave streak portions formed around the entire circumference of the body of the bottle with respect to the bottle axis line, and as a result, the concave streak portion is less than 31.5 ° with respect to the bottle axis line. When tilted at an angle, the deformation due to decompression inside the bottle is small, but the buckling strength is reduced, and the groove is tilted at an angle of more than 38.5 ° with respect to the axis of the bottle. On the other hand, it was found that while the buckling strength is improved, the deformation inside the bottle due to the pressure reduction is large.
【0011】 そこで、本考案は、前記の目的を達成するために、口部、胴部、底部から成る 二軸延伸ポリエチレンテレフタレート製ボトルにおいて、前記胴部の少なくとも 下半部の全周に、該ボトルの軸線に対して31.5°〜38.5°の範囲の角度 で傾斜する複数の傾斜凹条部を間隔を存して形成したことを特徴とする。Therefore, in order to achieve the above-mentioned object, the present invention provides a biaxially stretched polyethylene terephthalate bottle comprising a mouth, a body, and a bottom, at least on the entire circumference of the lower half of the body. The present invention is characterized in that a plurality of inclined groove portions that incline at an angle of 31.5 ° to 38.5 ° with respect to the axis of the bottle are formed at intervals.
【0012】[0012]
本考案のボトルによれば、その胴部の少なくとも下半部の全周に複数の凹条部 を間隔を存して形成し、且つ、該凹条部を該ボトルの軸線に対して31.5°〜 38.5°の範囲の角度で傾斜させて形成したので、ボトル内部の減圧に伴う変 形は小であると共に座屈強度が高い。 According to the bottle of the present invention, a plurality of groove portions are formed at intervals around at least the lower half portion of the body portion, and the groove portions are formed at 31.degree. With respect to the axis of the bottle. Since it was formed by inclining at an angle in the range of 5 ° to 38.5 °, the deformation due to the reduced pressure inside the bottle is small and the buckling strength is high.

本考案の一実施例を図面に基づいて説明する。 An embodiment of the present invention will be described with reference to the drawings.
【0014】 図1は本実施例の二軸延伸ポリエチレンテレフタレート製ボトル(以下単にP ETボトルと言う)を示す側面図、図2は図1のII−II線断面図である。FIG. 1 is a side view showing a biaxially stretched polyethylene terephthalate bottle of the present embodiment (hereinafter simply referred to as PET bottle), and FIG. 2 is a sectional view taken along line II-II of FIG.
【0015】 本実施例のPETボトル1は、ポリエチレンテレフタレート材料の延伸ブロー 成形により二軸配向して形成されたものであり、図1に示すように、口部2、胴 部3、底部4によって構成されている。該PETボトル1の容積は、液体内容物 を1リットル収納できるものとし、その高さ寸法を約256mmに形成されている 。更に、該PETボトル1の目付は比較的軽量の33gであり、これにより胴部 3の肉厚寸法は比較的薄い0.28〜0.30mmに形成されている。The PET bottle 1 of the present embodiment is formed by stretch blow molding of a polyethylene terephthalate material and is biaxially oriented. As shown in FIG. 1, the PET bottle 1 includes a mouth portion 2, a body portion 3 and a bottom portion 4. It is configured. The PET bottle 1 has a volume capable of accommodating 1 liter of liquid content and has a height dimension of about 256 mm. Further, the PET bottle 1 has a comparatively light weight of 33 g, so that the body portion 3 has a relatively thin wall thickness of 0.28 to 0.30 mm.
【0016】 前記胴部3の上半部3aには、その全周に水平に環状溝状の4本の水平凹条部 5が上下方向に等間隔で形成されている。該水平凹条部5は深さ約1.45mm、巾約 8.3mmに夫々形成されている。On the upper half portion 3a of the body portion 3, four horizontal groove-like horizontal groove portions 5 are formed horizontally in the vertical direction at equal intervals in the vertical direction. The horizontal recessed portion 5 is formed with a depth of about 1.45 mm and a width of about 8.3 mm, respectively.
【0017】 また、前記胴部3の下半部3bには、その全周に周方向にねじれて延びる8本 の傾斜凹条部6が等間隔で形成されている。各傾斜凹条部6は、該PETボトル 1の軸線yに対して35°の角度で傾斜して形成されている。該胴部3の下半部 3bの高さ寸法は約115.5mmに形成されており、前記傾斜凹条部6は該下半部 3bの高さ寸法の範囲内の約89.5mmにわたって、巾約22mm、深さ約3.5mmに 形成されている。Further, in the lower half portion 3b of the body portion 3, eight inclined groove portions 6 extending in a circumferential direction and extending in the circumferential direction are formed at equal intervals. Each inclined groove portion 6 is formed to be inclined at an angle of 35 ° with respect to the axis y of the PET bottle 1. The height dimension of the lower half portion 3b of the body portion 3 is formed to be about 115.5 mm, and the inclined groove portion 6 extends over about 89.5 mm within the height dimension of the lower half portion 3b. It has a width of about 22 mm and a depth of about 3.5 mm.
【0018】 更に、前記胴部3の中央部3cには括れ部7が形成されており、該括れ部7の 深さ寸法は約4.5mm程度に、その巾寸法は約25mmに形成されている。Further, a constricted portion 7 is formed in the central portion 3c of the body portion 3, and the constricted portion 7 has a depth dimension of about 4.5 mm and a width dimension of about 25 mm. There is.
【0019】 そして、前記口部2は、該PETボトル1の内部に液体内容物を充填したとき に図示しないキャップが冠着可能となっており、該キャップによって該PETボ トル1の内部に液体内容物が密封される。A cap (not shown) can be attached to the mouth portion 2 when the inside of the PET bottle 1 is filled with a liquid content, and the cap allows the liquid to be put inside the PET bottle 1. The contents are sealed.
【0020】 次に、以上の構成によるPETボトル1に液体内容物をホットパックにより充 填し密封した場合の作用を説明する。Next, the operation when the PET bottle 1 having the above-mentioned configuration is filled with a liquid content by a hot pack and hermetically sealed will be described.
【0021】 PETボトル1の内部に密封される液体内容物は通常70℃前後に加熱されて 充填されるため、PETボトル1に密封された状態で冷却される。これにより、 PETボトル1の内部では、液体内容物の温度の低下に伴って圧力が低下する。 PETボトル1の内部が減圧されると、PETボトル1の容積が減少してその胴 部3は内部方向に引っ張られる。このとき、図1及び図2に示すように、該PE Tボトル1はその下半部3bに前記傾斜凹条部6が形成されているので、該傾斜 凹条部6が胴部3の下半部3bの全周に均一なねじれ変形を促し、図2中誇張し て仮想線で示すように、該下半部3bが縮径し、該PETボトル1の容積減少分 が吸収される。これにより、下半部3bの変形が上半部3aに波及せず、PET ボトル1全体の外観が大きく変形することを防止することができる。The liquid content sealed inside the PET bottle 1 is usually heated to around 70 ° C. and filled, so that the PET bottle 1 is cooled in a sealed state. As a result, the pressure inside the PET bottle 1 decreases as the temperature of the liquid contents decreases. When the inside of the PET bottle 1 is depressurized, the volume of the PET bottle 1 is reduced and the body 3 of the PET bottle 1 is pulled inward. At this time, as shown in FIG. 1 and FIG. 2, since the PET bottle 1 has the inclined groove portion 6 formed in the lower half portion 3b thereof, the inclined groove portion 6 is located below the body portion 3. A uniform twisting deformation is promoted over the entire circumference of the half portion 3b, and the lower half portion 3b is reduced in diameter as shown by an imaginary line in an exaggerated manner in FIG. 2, and the volume reduction amount of the PET bottle 1 is absorbed. Thereby, the deformation of the lower half portion 3b does not affect the upper half portion 3a, and it is possible to prevent the appearance of the entire PET bottle 1 from being largely deformed.
【0022】 ここで、本発明者は、従来のPETボトル30(図3示)、本実施例のPET ボトル1(図1示)及び試験用PETボトル(図示しない)についての比較試験 を行った。Here, the present inventor conducted a comparative test on the conventional PET bottle 30 (shown in FIG. 3), the PET bottle 1 of the present embodiment (shown in FIG. 1) and the PET bottle for test (not shown). .
【0023】 従来のPETボトル30は、従来の技術の欄で述べたように、傾斜凹条部36 が該ボトル30の軸線yに対して30°の角度に傾斜しており、また、前記試験 用PETボトルは、傾斜凹条部が該ボトルの軸線に対して40°の角度に傾斜し ている。従来のPETボトル30及び試験用PETボトルの夫々の傾斜凹条部3 6以外の部分においては本実施例のPETボトル1と同様に形成されている。In the conventional PET bottle 30, as described in the section of the prior art, the inclined recessed portion 36 is inclined at an angle of 30 ° with respect to the axis y of the bottle 30, and the above-mentioned test is performed. The PET bottle for use has an inclined concave portion inclined at an angle of 40 ° with respect to the axis of the bottle. The portions other than the inclined recessed portions 36 of the conventional PET bottle 30 and the test PET bottle are formed similarly to the PET bottle 1 of this embodiment.
【0024】 なお、本実施例のPETボトル1は、従来のPETボトル30と同様に、胴部 3の肉厚が比較的薄い目付33gとされているが、本比較試験を行うにあたり比 較結果を明確にするために、目付33gのものだけでなく胴部3の肉厚を比較的 厚くした目付36gのものも使用し、同じく従来のPETボトル30や前記試験 用PETボトルにおいても目付33g及び目付36gのものを使用した。It should be noted that the PET bottle 1 of the present embodiment is similar to the conventional PET bottle 30 in that the body portion 3 has a relatively thin weight of 33 g. In order to clarify the above, not only those having a basis weight of 33 g but also those having a basis weight of 36 g in which the thickness of the body portion 3 is made relatively thick are used. Similarly, in the case of the conventional PET bottle 30 and the PET bottle for test, A product having a basis weight of 36 g was used.
【0025】 本比較試験は、上記の各PETボトル1,30に液体内容物を充填して密封し 、垂直荷重を加えて潰れ限界の重量(kg)の計測を行って座屈強度を測定すると 共に、胴部3,32の下半部3b,32cの周寸法の変化を計測して減圧変形を 測定した。即ち、座屈強度の測定は、夫々のPETボトル1,30に液体内容物 を常温で充填した場合と72℃に加熱した液体内容物を充填した場合とについて 行い、72℃に加熱した液体内容物を充填した場合においては、その充填直後及 び3日間放置して自然冷却した後に測定を行った。減圧変形の測定は、72℃に 加熱した液体内容物を充填して2週間放置し更に5℃に冷却した後に行った。In this comparative test, the above PET bottles 1 and 30 were filled with liquid contents and sealed, and a vertical load was applied to measure the crushing limit weight (kg) to measure the buckling strength. In both cases, the pressure reduction deformation was measured by measuring the change in the circumferential dimension of the lower half portions 3b and 32c of the body portions 3 and 32. That is, the buckling strength was measured for each of the PET bottles 1 and 30 filled with the liquid content at room temperature and with the liquid content heated to 72 ° C. When the product was filled, the measurement was carried out immediately after the filling and after being left to stand for 3 days and naturally cooled. The measurement of deformation under reduced pressure was performed after filling the liquid contents heated to 72 ° C., leaving it for 2 weeks, and further cooling to 5 ° C.
【0026】 本比較試験の結果を表1に示す。The results of this comparative test are shown in Table 1.
【0027】[0027]
【表1】 [Table 1]
【0028】 表1に示すように、傾斜凹条部36の傾斜角度が30°である従来のPETボ トル30は目付33gとしたものでは減圧変形が2.26mmと比較的小さい反面 、座屈強度が特に72℃充填直後で25.5kgと非常に低く、また、傾斜凹条部 の傾斜角度が40°である試験用PETボトルは目付33gとしたものでは座屈 強度が72℃充填直後であっても36.9kgと極めて高い反面、減圧変形が9. 56mmと非常に大きい。このように、本比較試験によって、傾斜凹条部の傾斜角 度が大きいほど座屈強度が高く、傾斜凹条部の傾斜角度が小さいほど減圧変形が 小さいことが判明した。As shown in Table 1, the conventional PET bottle 30 in which the inclination angle of the inclined recessed portion 36 is 30 ° has a weight of 33 g, the pressure reduction deformation is relatively small at 2.26 mm, but the buckling The strength is extremely low, especially 25.5 kg immediately after filling at 72 ° C, and the PET bottle for testing with an inclined angle of the inclined groove of 40 ° has a buckling strength immediately after filling at 72 ° C with a unit weight of 33 g. Even if there is 36.9 kg, it is extremely high, but the reduced pressure deformation is 9. Very large at 56 mm. As described above, this comparative test revealed that the buckling strength is higher as the inclination angle of the inclined groove is larger, and the reduced pressure deformation is smaller as the inclination angle of the inclined groove is smaller.
【0029】 そして、表1に示すように、本実施例のPETボトル1は、肉厚が薄い目付3 3gであっても各傾斜凹条部6の傾斜角度を35°とすることによって、72℃ 充填直後に35.4kgと極めて高く、従来のPETボトル30の目付33gのも のよりも飛躍的に高い座屈強度を得ることができるだけでなく、従来のPETボ トル30の肉厚を増して目付36gとしたものよりも高い座屈強度を得ることが でる。しかも、本実施例のPETボトル1の目付33gのもので減圧変形が3. 43mmであり、従来のPETボトル30の2.26mmより減圧変形が大きくても その差が1.17mm程度と極めて些少であるのでホットパック用の容器として好 適であることが明らかとなった。Then, as shown in Table 1, in the PET bottle 1 of the present embodiment, even if the weight of the PET bottle 1 is 33 g, the inclination angle of each inclined groove portion 6 is set to 35 °. ℃ Immediately after filling, it is extremely high at 35.4 kg, and it is possible to obtain a much higher buckling strength than that of the conventional PET bottle 30 having a basis weight of 33 g, and also to increase the thickness of the conventional PET bottle 30. It is possible to obtain a higher buckling strength than that with a basis weight of 36 g. Moreover, the PET bottle 1 of the present embodiment having a basis weight of 33 g has a reduced pressure deformation of 3. It is 43 mm, and even if the reduced pressure deformation is larger than 2.26 mm of the conventional PET bottle 30, the difference is about 1.17 mm, which is extremely small, so it was clarified that it is suitable as a container for hot packs.
【0030】 なお、本実施例では、PETボトル1の各傾斜凹条部6の傾斜角度を35°と したが、各傾斜凹条部6の傾斜角度は、31.5°〜38.5°の範囲の角度で あれば、本実施例のPETボトル1と同程度の効果を得ることができる。In this embodiment, the inclination angle of each inclined groove 6 of the PET bottle 1 is set to 35 °, but the inclination angle of each inclined groove 6 is 31.5 ° to 38.5 °. If the angle is within the range, the same effect as that of the PET bottle 1 of this embodiment can be obtained.
【0031】[0031]
以上のことから明らかなように、本考案は、その胴部の少なくとも下半部の全 周に複数の傾斜凹条部を間隔を存して形成し、更に、該傾斜凹条部を該ボトルの 軸線に対して31.5°〜38.5°の範囲の角度で傾斜させて形成することに より、例えば、ホットパックによる内容物の充填密封時に、ボトル内部の減圧に 伴う変形を小とすることができ、しかも、肉厚を厚くすることなく座屈強度を飛 躍的に向上させることができる。 As is clear from the above, according to the present invention, a plurality of inclined ridges are formed at intervals around at least the lower half of the body, and the inclined ridges are formed in the bottle. By inclining at an angle in the range of 31.5 ° to 38.5 ° with respect to the axis of, the deformation due to the depressurization inside the bottle can be made small, for example, when filling and sealing the contents with a hot pack. In addition, the buckling strength can be dramatically improved without increasing the wall thickness.
【0032】 従って、本考案によれば、肉厚が比較的薄くてもよいので材料コストを増加さ せることなく、減圧変形を小とし且つ座屈強度の高い形状の二軸延伸ポリエチレ ンテレフタレート製ボトルを提供することができる。Therefore, according to the present invention, since the wall thickness may be relatively thin, the biaxially stretched polyethylene terephthalate made of a biaxially stretched polyethylene terephthalate having a shape with a small deformation under reduced pressure and a high buckling strength without increasing the material cost. Bottles can be provided.
