Description

樹脂製ボトルPlastic bottle
　本発明は、樹脂製ボトルに関する。 The present invention relates to a resin bottle.
　飲料品として飲料を充填させた樹脂製ボトルは、炭酸飲料を充填した場合や、市場に流通する過程である程度高温下（例えば４０℃程度）に置かれることにより、内圧が高まることがある。その結果、樹脂製ボトルは、流通過程や流通後に、内圧上昇による膨張によってボトル形状が変形するおそれがある。そして、このようなボトル形状の変形を抑制するために、一般に補強用のリブが設けられている。 Resin bottles filled with beverages as beverages may have increased internal pressure when filled with carbonated beverages or placed at a certain high temperature (for example, about 40 ° C.) in the course of distribution to the market. As a result, the bottle shape of the resin bottle may be deformed by expansion due to an increase in internal pressure after the distribution process or distribution. And in order to suppress such a deformation | transformation of a bottle shape, the rib for reinforcement is generally provided.
　近年、ボトル自体に装飾を施して意匠的効果を狙うことが行われている。しかし、内圧上昇によるボトル形状の変形により、装飾の意匠的効果が奏しなくなることがあった。 In recent years, decoration has been performed on the bottle itself to aim for a design effect. However, due to the deformation of the bottle shape due to the increase in internal pressure, the decorative design effect may not be achieved.
　そこで、意匠的効果を奏しつつ、ボトル形状の変形を抑制し得る樹脂製ボトルの実現が望まれる。 Therefore, it is desired to realize a resin bottle capable of suppressing the deformation of the bottle shape while exhibiting a design effect.
　本発明に係る樹脂製ボトルは、
　少なくとも一部の領域に所定パターンで配置されるそれぞれ面積が１～１００ｍｍ２の複数の窪みが設けられている。 The resin bottle according to the present invention is:
A plurality of depressions each having an area of 1 to 100 mm 2 are provided in at least a part of the region in a predetermined pattern.
　この構成によれば、複数の窪みにより内圧上昇によるボトル形状の変形を効果的に抑制することができる。そして、窪みの配置パターンにより意匠的効果を奏することも可能となる。 According to this configuration, the deformation of the bottle shape due to the increase in internal pressure can be effectively suppressed by the plurality of depressions. Further, it is possible to achieve a design effect by the arrangement pattern of the depressions.
　以下、本発明に係る樹脂製ボトルの好適な態様について説明する。但し、以下に記載する好適な態様例によって、本発明の範囲が限定される訳ではない。 Hereinafter, preferred embodiments of the resin bottle according to the present invention will be described. However, the scope of the present invention is not limited by the preferred embodiments described below.
　１つの態様として、各窪みの表面にはシボが形成されていると好適である。 As one aspect, it is preferable that a texture is formed on the surface of each recess.
　各窪みにシボ（細かい凹凸の模様）を形成することにより、内圧上昇によるボトル形状の変形を一層効果的に抑制することができる。さらに、シボによって各窪みがくっきりと際立って視認性が向上し、窪みによる意匠的効果も一層向上する。そして、シボを形成するためには、ブロー成形時に金型に樹脂がしっかりと押し当てられなければならないが、窪みにシボを形成する際には金型の突起部分に樹脂を沿わせることになり、突起部分に樹脂が強く押し当てられることとなるため、シボを好適に形成することができる。 シ By forming wrinkles (fine concavo-convex patterns) in each depression, it is possible to more effectively suppress the deformation of the bottle shape due to an increase in internal pressure. In addition, the depressions clearly and clearly improve the depression, and the design effect by the depression is further improved. In order to form a texture, the resin must be firmly pressed against the mold during blow molding. However, when forming a texture in the recess, the resin is placed along the protrusion of the mold. Since the resin is strongly pressed against the protruding portion, the texture can be suitably formed.
　１つの態様として、各窪みは多角形状又は円状であると好適である。 As one aspect, each recess is preferably polygonal or circular.
　この構成によれば、各窪みが対称性の高い形状となって、内圧上昇によるボトル形状の変形を一層効果的に抑制することができ、且つ、意匠的効果も一層向上する。 According to this configuration, each recess has a highly symmetric shape, so that the deformation of the bottle shape due to the increase in internal pressure can be more effectively suppressed, and the design effect can be further improved.
　１つの態様として、ボトル全体の所定範囲を占める１又は複数の帯状の領域の一帯に前記窪みが形成されていると好適である。 As one aspect, it is preferable that the depression is formed in one zone of one or a plurality of belt-like regions occupying a predetermined range of the entire bottle.
　この構成によれば、帯状の領域の一帯に窪みが形成されていることにより、内圧上昇によるボトル形状の変形を一層効果的に抑制することができる。 According to this configuration, since the depression is formed in the belt-shaped region, the deformation of the bottle shape due to the increase in internal pressure can be more effectively suppressed.
　１つの態様として、前記窪みが設けられていない高さ方向における所定範囲の領域に、並列する複数のリブを備えるリブ域が形成されていると好適である。 As one aspect, it is preferable that a rib region including a plurality of ribs arranged in parallel is formed in a region in a predetermined range in the height direction where the depression is not provided.
　複数の窪みによれば内圧上昇によるボトル形状の変形を抑制できるが、許容範囲を超えたときには窪みが張り出すことになり、美観が損なわれる。そこで、この構成では、単に窪みのみを全体に設けるのではなくリブ域を設けることにより、内圧の上昇に伴い窪みに先立ってリブ域が変形することになり、窪みの膨張を抑制することができ、内圧上昇によるボトル形状の変形を一層効果的に抑制できる。 複数 According to the plurality of depressions, it is possible to suppress the deformation of the bottle shape due to an increase in internal pressure, but when the tolerance exceeds the allowable range, the depressions protrude and the aesthetics are impaired. Therefore, in this configuration, by providing the rib area instead of simply providing the entire depression, the rib area is deformed prior to the depression as the internal pressure increases, and expansion of the depression can be suppressed. Further, it is possible to more effectively suppress the deformation of the bottle shape due to the increase in internal pressure.
　１つの態様として、ラベルが設けられる高さ方向の範囲に前記リブ域が形成されていると好適である。 As one aspect, it is preferable that the rib area is formed in a range in the height direction where the label is provided.
　この構成によれば、美観に乏しいリブ域がラベルで隠されることになるので、内圧上昇によるボトル形状の変形を抑制しながらも、意匠的効果を維持できる。 According to this configuration, since the rib area having poor aesthetics is hidden by the label, the design effect can be maintained while suppressing the deformation of the bottle shape due to the increase in internal pressure.
　１つの態様として、前記リブ域における各リブは、所定長さの複数の凹部が間隔を空けて各リブの延在方向に連なっている不連続リブであると好適である。 As one aspect, it is preferable that each rib in the rib area is a discontinuous rib in which a plurality of concave portions having a predetermined length are connected in the extending direction of each rib with a space therebetween.
　この構成によれば、リブが不連続リブで形成されていることにより、凹部間の不連続部分によりリブが延在方向に延びることを効果的に抑制でき、内圧上昇によるボトル形状の変形を一層効果的に抑制できる。 According to this configuration, since the ribs are formed of discontinuous ribs, it is possible to effectively suppress the ribs from extending in the extending direction due to the discontinuous portions between the recesses, and the bottle-shaped deformation due to the increase in internal pressure is further reduced. It can be effectively suppressed.
　１つの態様として、前記リブ域は、前記不連続リブの並列方向において、前記不連続リブにおける前記凹部間の不連続部分が、隣接する前記不連続リブにおける前記不連続部分とは重複しない状態で形成されていると好適である。 As one aspect, the rib region is in a state where the discontinuous portions between the recesses in the discontinuous ribs do not overlap the discontinuous portions in the adjacent discontinuous ribs in the parallel direction of the discontinuous ribs. Preferably it is formed.
　凹部及び不連続部分が並列方向に重複した場合には、凹部がバネのように働くこととなりボトル強度が低下する虞があるが、この構成によれば、隣接する不連続リブにおいて不連続部分が並列方向に重複しないように設けられているから、凹部及び不連続部分が並列方向に重複することによる問題を効果的に抑制できる。 When the concave portion and the discontinuous portion overlap in the parallel direction, the concave portion works like a spring and the bottle strength may be reduced, but according to this configuration, the discontinuous portion is adjacent to the discontinuous rib. Since it is provided so that it may not overlap in the parallel direction, the problem by a recessed part and a discontinuous part overlapping in a parallel direction can be suppressed effectively.
　１つの態様として、前記リブ域では、前記リブが周方向に延びる状態で形成されていると好適である。 As one aspect, in the rib region, it is preferable that the rib is formed in a state extending in the circumferential direction.
　この構成によれば、リブを周方向に延びるようにすることにより、ボトルが径方向に膨張することを効果的に抑制できる。 According to this configuration, it is possible to effectively suppress the bottle from expanding in the radial direction by extending the rib in the circumferential direction.
　１つの態様として、炭酸飲料用であると好適である。 As one aspect, it is suitable for carbonated drinks.
　この構成によれば、内圧が高まりやすい炭酸飲料用のボトルであっても、内圧上昇によるボトル形状の変形を一層効果的に抑制できる。 According to this configuration, even for a carbonated beverage bottle whose internal pressure is likely to increase, deformation of the bottle shape due to an increase in internal pressure can be more effectively suppressed.

　本発明に係る樹脂製ボトルの実施形態について、図面を参照して説明する。本実施形態に係る樹脂製ボトル１は、図１に示すように、液体の注ぎ口としての口部２と、口部２と連続し、底面方向に向かうにつれて徐々に拡径する肩部３と、肩部３と連続する円筒状の胴部４と、樹脂製ボトル１の底となる底部５と、から構成されている。本実施形態に係る樹脂製ボトル１は炭酸飲料用であり、内圧上昇によるバックリングを抑制するために、底部５はいわゆるペタロイド形状となっている。そして、本実施形態に係る樹脂製ボトル１は、意匠的効果を奏しつつ、ボトル形状の変形を抑制し得る構成を採用しており、以下、本実施形態に係る樹脂製ボトル１について詳細に説明する。 Embodiments of a resin bottle according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the resin bottle 1 according to the present embodiment includes a mouth 2 as a liquid spout, a shoulder 3 that is continuous with the mouth 2 and gradually increases in diameter toward the bottom surface. The cylindrical body 4 is continuous with the shoulder 3, and the bottom 5 is the bottom of the resin bottle 1. The resin bottle 1 according to this embodiment is for carbonated drinks, and the bottom 5 has a so-called petaloid shape in order to suppress buckling due to an increase in internal pressure. And the resin-made bottle 1 which concerns on this embodiment has employ | adopted the structure which can suppress a deformation | transformation of a bottle shape, producing | playing a design effect, and demonstrates the resin bottle 1 which concerns on this embodiment in detail hereafter. To do.
　まず、本実施形態に係る樹脂製ボトル１は、例えば、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレート等の熱可塑性樹脂を主材料として、二軸延伸ブロー成形等の延伸成形法によって一体的に成形することができる。樹脂製ボトル１の容量は本実施形態ではおよそ１．５リットルとしてあるが特に限定されず、一般的に流通している２００ミリリットル～２リットル程度とすることができる。また、樹脂製ボトル１に充填させる液体は特に限定されず、炭酸飲料の他、例えば、飲料水、茶、果汁、コーヒー、ココア、清涼飲料水、アルコール飲料、乳飲料、スープなどの飲料や、ソースや醤油などの液体調味料などが挙げられる。 First, the resin bottle 1 according to the present embodiment can be integrally molded by a stretch molding method such as biaxial stretch blow molding using a thermoplastic resin such as polyethylene, polypropylene, polyethylene terephthalate, or the like as a main material. . The capacity of the resin bottle 1 is about 1.5 liters in this embodiment, but is not particularly limited, and can be about 200 milliliters to 2 liters that are generally distributed. The liquid to be filled in the resin bottle 1 is not particularly limited, and in addition to carbonated beverages, for example, beverages such as drinking water, tea, fruit juice, coffee, cocoa, soft drinks, alcoholic beverages, milk beverages, soups, Examples include liquid seasonings such as sauces and soy sauce.
　図１に示すように、本実施形態に係る樹脂製ボトル１は、少なくとも一部の領域に、より具体的には、ボトル全体の所定範囲を占める複数の（２つの）周方向の帯状領域６，７の一帯に、複数の窪み８が設けられている。帯状領域６は肩部３の下側部分から胴部４の上側部分にわたる領域に当たり、帯状領域７は胴部４の下側部分にわたる領域に当たり、胴部４の真ん中付近から胴部４と底部５との境界にわたっている。このため、胴部４については、後述するリブ域９を除く部分に窪み８が満遍なく設けられた状態となっている。また、各窪み８は対角線の長さが４ｍｍ（縦方向）・２ｍｍ（横方向）の菱形状であり、深さが０．５ｍｍとなっている。そして、図１，２に示すように、各窪み８は互いに間隔を空けて、六方格子状に規則的に配置されている。 As shown in FIG. 1, the resin bottle 1 according to the present embodiment has a plurality of (two) circumferential belt-like regions 6 that occupy a predetermined range of the entire bottle in at least a part of the region. , 7 is provided with a plurality of depressions 8. The belt-like region 6 hits the region extending from the lower part of the shoulder 3 to the upper part of the trunk 4, and the belt-like region 7 hits the area spanning the lower part of the trunk 4, and from the middle of the trunk 4 to the trunk 4 and the bottom 5. And across the border. For this reason, about the trunk | drum 4, it is in the state by which the hollow 8 was provided uniformly in the part except the rib area | region 9 mentioned later. Each depression 8 has a rhombus shape with a diagonal length of 4 mm (vertical direction) and 2 mm (horizontal direction), and a depth of 0.5 mm. As shown in FIGS. 1 and 2, the recesses 8 are regularly arranged in a hexagonal lattice pattern at intervals.
　このような窪み８により内圧上昇によるボトル形状の変形を効果的に抑制することができる。さらに、各窪み８が多角形である菱形状であること、及び、各窪み８を六方格子状に配置することで帯状領域６，７を多数の窪み８で密に充填することにより変形抑制効果を一層高めてある。そして、対称形状の菱形が規則的なパターンで埋められていることにより意匠的効果も向上する。 Such a depression 8 can effectively suppress the deformation of the bottle shape due to an increase in internal pressure. Furthermore, each depression 8 has a polygonal rhombus shape, and by arranging the depressions 8 in a hexagonal lattice shape, the band- shaped regions 6 and 7 are densely filled with a large number of depressions 8 to suppress deformation. Is even higher. And the design effect is also improved by filling the symmetrical rhombus with a regular pattern.
　また、各窪み８の大きさを対角線の長さが４ｍｍ（縦方向）・２ｍｍ（横方向）程度の大きさとすることで、窪み８の境界部分の曲率を大きくすることができ、変形抑制効果を高めてある。なお、各窪み８の大きさは、対角線の長さがそれぞれ１～１０ｍｍであれば良く、面積として１～１００ｍｍ２であると好適である。１００ｍｍ２以下であれば、窪み８の境界部分の曲率が大きくなり、変形抑制効果を高めることができ、また、１ｍｍ２未満であるとブロー成形等の成形法では正確に窪み８を形成することが困難となるためである。また、深さは０．５ｍｍに限らず、０．２～３ｍｍであれば良い。 Moreover, the curvature of the boundary part of the dent 8 can be enlarged by making the size of each dent 8 into the length of a diagonal line about 4 mm (vertical direction) * 2 mm (lateral direction), and a deformation suppression effect. Is raised. The size of each recess 8 may be such that the length of the diagonal line is 1 to 10 mm, and the area is preferably 1 to 100 mm 2 . If it is 100 mm 2 or less, the curvature of the boundary portion of the depression 8 is increased, and the effect of suppressing deformation can be enhanced. If it is less than 1 mm 2 , the depression 8 can be accurately formed by a molding method such as blow molding. This is because it becomes difficult. Further, the depth is not limited to 0.5 mm, but may be 0.2 to 3 mm.
　また、各窪み８の表面にはシボ（細かい凹凸の模様）が形成されている。このシボは、ブロー成形に用いる金型における窪み８に相当する突起部分にシボを形成し、ブロー成形時において、金型に樹脂を押し当てることで形成できる。突起部分に樹脂を強く押し当てる形態でシボが形成されることとなるため、シボを好適に形成することができる。このようなシボを形成することにより、内圧上昇によるボトル形状の変形を効果的に抑制することができ、さらに、シボによって各窪み８がくっきりと際立って視認性が向上し、窪み８による意匠的効果も向上する。 In addition, the surface of each recess 8 is formed with wrinkles (fine uneven patterns). This texture can be formed by forming a texture on the protrusion corresponding to the depression 8 in the mold used for blow molding, and pressing the resin against the mold during blow molding. Since the wrinkles are formed in a form in which the resin is strongly pressed against the protruding portions, the wrinkles can be suitably formed. By forming such a wrinkle, the deformation of the bottle shape due to an increase in internal pressure can be effectively suppressed. Further, the wrinkles 8 are clearly distinguished by the wrinkles, and the visibility is improved. The effect is also improved.
　さらに、本実施形態の樹脂製ボトル１は、窪み８が設けられていない高さ方向における所定範囲の領域に（具体的にはラベルが設けられる高さ方向の範囲）、周方向に延びる複数のリブ１０を並列して備えるリブ域９が形成されている。複数の窪み８によれば内圧上昇によるボトル形状の変形を抑制できるが、許容範囲を超えたときには各窪み８が張り出すことになり、美観が損なわれる。そこで、リブ域９を設けることにより、内圧の上昇に伴い各窪み８に先立ってリブ域９が変形することになり、各窪み８の膨張を抑制することができる。また、リブ１０が周方向に延びているため、内圧の上昇により、樹脂製ボトル１が径方向に膨張することを効果的に抑制できる。 Furthermore, the resin bottle 1 of the present embodiment has a plurality of circumferentially extending areas in a predetermined range in the height direction where the recess 8 is not provided (specifically, a range in the height direction where the label is provided). A rib area 9 having ribs 10 arranged in parallel is formed. According to the plurality of depressions 8, it is possible to suppress the deformation of the bottle shape due to an increase in internal pressure. However, when the tolerance is exceeded, each depression 8 protrudes, and the aesthetic appearance is impaired. Therefore, by providing the rib areas 9, the rib areas 9 are deformed prior to the respective depressions 8 as the internal pressure increases, and the expansion of the respective depressions 8 can be suppressed. Moreover, since the rib 10 is extended in the circumferential direction, it can suppress effectively that the resin bottle 1 expand | swells to a radial direction by the raise of internal pressure.
　リブ域９における各リブ１０は、所定長さの複数の凹部１１が間隔を空けて各リブ１０の延在方向（本実施形態では周方向）に連なっている不連続リブとなっている。そして、不連続リブ１０の並列方向（本実施形態では高さ方向）において、不連続リブ１０における凹部１１間の不連続部分１２が、隣接する不連続リブ１０における不連続部分１２とは重複しない状態で形成されている。より具体的には、不連続リブ１０における各凹部１１の中心位置が、隣接する不連続リブ１０における各不連続部分１２の中心位置と一致するようになっており、凹部１１と不連続部分１２とが隣接する不連続リブ１０において互い違いとなる状態で配置されている。リブ１０が不連続リブで形成されていることにより、凹部１１間の不連続部分１２によりリブ１０が延在方向に延びることを効果的に抑制でき、内圧上昇によるボトル形状の変形を一層効果的に抑制できる。そして、凹部１１及び不連続部分１２が並列方向に重複した場合には、凹部１１がバネのように働くこととなりボトル強度が低下する虞があるが、隣接する不連続リブ１０において不連続部分１２が並列方向に重複しないように設けられているから、凹部１１及び不連続部分１２が並列方向に重複することによる問題を効果的に抑制できる。 Each rib 10 in the rib area 9 is a discontinuous rib in which a plurality of concave portions 11 having a predetermined length are connected to each other in the extending direction (circumferential direction in the present embodiment) of each rib 10 with a space therebetween. In the parallel direction of the discontinuous ribs 10 (the height direction in this embodiment), the discontinuous portions 12 between the recesses 11 in the discontinuous ribs 10 do not overlap with the discontinuous portions 12 in the adjacent discontinuous ribs 10. It is formed in a state. More specifically, the center position of each recess 11 in the discontinuous rib 10 matches the center position of each discontinuous portion 12 in the adjacent discontinuous rib 10. Are arranged alternately in adjacent discontinuous ribs 10. By forming the ribs 10 as discontinuous ribs, it is possible to effectively suppress the ribs 10 from extending in the extending direction due to the discontinuous portions 12 between the recesses 11, and to further effectively deform the bottle shape due to an increase in internal pressure. Can be suppressed. And when the recessed part 11 and the discontinuous part 12 overlap in the parallel direction, the recessed part 11 works like a spring and there is a possibility that the bottle strength may be reduced. Is provided so as not to overlap in the parallel direction, the problem caused by the overlapping of the recess 11 and the discontinuous portion 12 in the parallel direction can be effectively suppressed.
　また、本実施形態の樹脂製ボトル１では、ラベルが設けられる高さ方向の範囲にリブ域９が形成されている。これにより、美観に乏しいリブ域９がラベルで隠されることになるので、内圧上昇によるボトル形状の変形を抑制しながらも、意匠的効果を高く確保できる。 Moreover, in the resin bottle 1 of the present embodiment, the rib region 9 is formed in the range in the height direction where the label is provided. Thereby, since the rib area 9 with poor aesthetics is concealed by the label, it is possible to ensure a high design effect while suppressing deformation of the bottle shape due to an increase in internal pressure.
　このように、本実施形態の樹脂製ボトル１によれば、所定の大きさの窪み８を所定のパターンで設けることにより、意匠的効果を奏しつつ、ボトル形状の変形を抑制することができる。そして、複数の窪み８に加えて、リブ域９を設けることにより、各窪み８の膨張を抑制することができ、複数の窪み８による意匠的効果を保持しつつ、ボトル形状の変形を一層抑制することが可能となっている。 Thus, according to the resin bottle 1 of the present embodiment, by providing the depressions 8 having a predetermined size in a predetermined pattern, it is possible to suppress the deformation of the bottle shape while exhibiting a design effect. And by providing the rib area | region 9 in addition to the several hollow 8, expansion | swelling of each hollow 8 can be suppressed, and the deformation | transformation of a bottle shape is further suppressed, maintaining the design effect by the several hollow 8. FIG. It is possible to do.
