本考案は、二軸延伸ブロー成形されたAN（ア
クリルニトル）樹脂製壜体の底部に嵌合組付けさ
れる、ベースカツプに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a base cup that is fitted and assembled to the bottom of a biaxially stretched blow-molded AN (acrylic nitrile) resin bottle.
最近、ジユースや醤油等の容器として合成樹脂
製の壜体が広く使用されている。
Recently, synthetic resin bottles have been widely used as containers for juice, soy sauce, and the like.
中でも、二軸延伸ブロー成形されたPET（ポリ
エチレンテレフタレート）樹脂製のものが、それ
が持つ多くの特性により、最も数多く使用されて
いる。 Among them, those made of biaxially stretch blow-molded PET (polyethylene terephthalate) resin are the most commonly used because of their many properties.
しかし、このPET樹脂製の壜体にも耐熱性に
欠けるという大きな欠点がある。そのため、例え
ば、白化現象をおこし、壜体の劣化を招いたり、
外観を悪くすることもある。 However, this PET resin bottle also has a major drawback: it lacks heat resistance. Therefore, for example, it may cause a whitening phenomenon and cause deterioration of the bottle.
It may also make the appearance worse.
従つて、この二軸延伸ブロー成形されたPET
樹脂製壜体は、コーラ等、熱処理を必要としない
ものを収納する壜体としては適しているが、逆
に、果汁入りジユース等、熱処理を必要とするも
のを収納する壜体としては問題が残る。 Therefore, this biaxially stretched blow molded PET
Resin bottles are suitable for storing things that do not require heat treatment, such as cola, but conversely, they are problematic when used to store things that require heat treatment, such as juice bottles containing fruit juice. remain.
そのため、この耐熱性に問題のあるPET樹脂
に代わつて、耐熱性の優れるAN樹脂の使用が考
えられる。 Therefore, instead of PET resin, which has a problem with heat resistance, it is possible to use AN resin, which has excellent heat resistance.
しかし、このAN樹脂にも又、問題点がある。
それは、上記したように、この二軸延伸成形され
たAN樹脂はPET樹脂と比較して耐熱性に優れて
はいるものの、反面、脆弱であり、耐衝撃性に劣
るということである。
However, this AN resin also has problems.
This is because, as mentioned above, although this biaxially stretched AN resin has superior heat resistance compared to PET resin, it is brittle and has poor impact resistance.
又、この壜体は、二軸延伸ブロー成形されると
いうことで、壜体底壁は半球殻状にすることが成
形上、並びに壜体の性能上望ましい。従つて、底
壁が半球殻状に成形されたこの壜体は、自立機能
を持たないことになる。 Furthermore, since this bottle is biaxially stretch blow molded, it is desirable for the bottom wall of the bottle to have a hemispherical shell shape from the viewpoint of molding and the performance of the bottle. Therefore, this bottle whose bottom wall is shaped like a hemispherical shell does not have a self-supporting function.
本考案は、上記した二つの問題点を解消するた
めに考え出されたもので、脆弱な壜体底部の耐衝
撃性を強化すると共に、壜体に自立機能をもたせ
るベースカツプを提供することを目的とする。 The present invention was devised in order to solve the above two problems, and aims to provide a base cup that strengthens the impact resistance of the fragile bottom of the bottle and gives the bottle a self-supporting function. shall be.
上記の目的を達成するために、以下の構成とし
ている。
In order to achieve the above purpose, the following configuration is adopted.
本考案による二軸延伸ブロー成形壜体用ベース
カツプ１は、二軸延伸ブロー成形され半球殻状の
底壁１０をもつAN樹脂製壜体８の底部に嵌合組
付けされる弾力のあるベースカツプ１であつて、
上端部が壜体胴筒９下端部に嵌合して組付く筒状
の胴筒２と、その胴筒２下端に連設された底板３
とから成つている。 The base cup 1 for a biaxially stretched blow-molded bottle according to the present invention is a resilient base cup 1 that is fitted and assembled to the bottom of an AN resin bottle 8 that is biaxially stretched blow-molded and has a bottom wall 10 in the shape of a hemispherical shell. And,
A cylindrical body tube 2 whose upper end fits into the lower end portion of the bottle body tube 9 and is assembled, and a bottom plate 3 connected to the lower end of the body tube 2.
It consists of.
そして、その底板３を前記胴筒２下端に連設さ
れ内方へ反転湾曲した脚部４と、その脚部４の内
側上端から内鍔状に連設され先端部上面が前記壜
体底壁１０に弾接する弾接部５と、前記脚部４の
上端から起立設し前記壜体８に嵌合組付けされた
状態において上端が、その壜体８の底壁１０に近
接する突部６とから構成している。 The bottom plate 3 is connected to the lower end of the body cylinder 2 and is invertedly curved inwardly, and the leg part 4 is connected from the inner upper end of the leg part 4 in the shape of an inner flange, and the upper surface of the tip part is connected to the bottom wall of the bottle body. 10; and a protrusion 6 that stands up from the upper end of the leg 4 and whose upper end is close to the bottom wall 10 of the bottle 8 when it is fitted and assembled to the bottle 8. It consists of.
従つて、ベースカツプ底板３の中央部には孔１
２が形成されている。 Therefore, a hole 1 is formed in the center of the base cup bottom plate 3.
2 is formed.
上記した構成となつている本考案は、脚部４を
設けているので、壜体８底部に嵌合組付けするこ
とで壜体８に自立機能をもたせることが出来る。
Since the present invention having the above-mentioned structure is provided with the legs 4, by fitting and assembling them to the bottom of the bottle 8, the bottle 8 can have a self-supporting function.
又、壜体８に組付けられたベースカツプ１に衝
撃が加わると、弾力のあるベースカツプ１は弾性
変形することによつて、その衝撃力を弱める働き
をするが、中でも、内周端部が壜体底壁１０に当
接し、最も弾性変形をおこし易い形状となつてい
る弾接部５は大きく下方に弾性変形し、壜体底壁
１０に近接している突部６の上端面が底壁１０に
当たる。 Furthermore, when an impact is applied to the base cup 1 assembled to the bottle body 8, the resilient base cup 1 acts to weaken the impact force by elastically deforming. The elastic contact portion 5 that is in contact with the bottom wall 10 and has a shape that is most likely to cause elastic deformation is elastically deformed significantly downward, and the upper end surface of the protrusion 6 that is close to the bottom wall 10 of the bottle becomes the bottom wall. It's 10.
これにより、弾接部５に加わる力を一定以内の
ものとすることで弾接部５の大きな弾性変形を防
ぎ、その弾接部５の大きな弾性変形が原因でベー
スカツプ１の壜体８に対する正常な組付き姿勢が
くずれるのを防いでいる。つまり、突部６上端面
が底壁１０に当接することにより、壜体８のベー
スカツプ１に対する一定以上の嵌合や、壜体８が
正位置からずれるのを防ぐという歯止めの役目を
しているわけであり、これにより壜体８とベース
カツプ１の組付きを安定したものにしているので
ある。 This prevents large elastic deformation of the elastic contact part 5 by keeping the force applied to the elastic contact part 5 within a certain level, and prevents the base cup 1 from moving normally against the bottle body 8 due to the large elastic deformation of the elastic contact part 5. This prevents the assembled position from collapsing. In other words, the upper end surface of the protrusion 6 comes into contact with the bottom wall 10, thereby acting as a brake to prevent the bottle 8 from fitting into the base cup 1 beyond a certain level or from shifting from its normal position. This makes the assembly of the bottle body 8 and base cup 1 stable.
〔実施例〕
本考案の一実施例を、図を参照しながら説明す
る。[Example] An example of the present invention will be described with reference to the drawings.
このベースカツプ１は弾力に富む合成樹脂製
で、ベースカツプ１との嵌合位置を設定するため
の係止条１１を円筒形状の胴体９に周設した壜体
８に嵌合組付きしたものを示している。 This base cup 1 is made of a highly elastic synthetic resin, and is assembled into a bottle body 8 having a cylindrical body 9 and a locking strip 11 for setting the fitting position with the base cup 1. ing.
突部６上端と、それに対向する底壁１０間の間
〓１３は、ベースカツプ１に壜体８との組付き位
置関係をくるわすほどの大きな衝撃力が作用する
と、突部６上端が底壁１０に当接してベースカツ
プ１と壜体８との組付き位置関係のくるいを阻止
する程度の大きさに設定されている。 The gap 13 between the upper end of the protrusion 6 and the bottom wall 10 facing it is such that when a large impact force is applied to the base cup 1 that changes the assembly position with the bottle body 8, the upper end of the protrusion 6 will close to the bottom wall. The size is set to such an extent that the base cup 1 and the bottle body 8 come into contact with each other and prevent the assembly positional relationship between the base cup 1 and the bottle body 8 from changing.
弾接部５内面には複数の突起７が設けられ、特
にベースカツプ１に衝撃が加わつた時に壜体底壁
１０とのすべりを防止することにより、壜体８と
の組付き位置関係を安定したものにしている。 A plurality of protrusions 7 are provided on the inner surface of the resilient contact portion 5, which stabilizes the assembled positional relationship with the bottle 8 by preventing slippage with the bottle bottom wall 10, especially when an impact is applied to the base cup 1. I'm making it a thing.
弾接部５は壜体８を安定良く支えることが必要
で、そのため、この弾接部５の位置は、壜体８の
中心とか外周端に片寄ることは避けなければなら
ない。ここでは、壜体８の中心と外周端とのほぼ
中間に設定位置させている。 It is necessary for the elastic contact part 5 to stably support the bottle 8, and therefore, the position of the elastic contact part 5 must be avoided from being biased toward the center or the outer peripheral edge of the bottle 8. Here, it is positioned approximately midway between the center of the bottle 8 and the outer peripheral edge.
又、このベースカツプ１は耐衝撃性を高める一
工夫として曲折部分は曲線状としており、衝撃力
が一箇所に集中することによりベースカツプ１が
壊れ易くなるのを防止している。 In addition, the bent portion of the base cup 1 is curved as a measure to increase impact resistance, thereby preventing the base cup 1 from becoming easily broken due to impact force being concentrated in one place.
このように本考案は、従来の問題点を解決し、
脆弱で耐衝撃性に劣る二軸延伸成形され底部が半

In this way, the present invention solves the conventional problems and
This is an excellent base cup that is able to give self-supporting functionality to the AN resin bottle, which is brittle and has poor impact resistance and has a hemispherical bottom that is biaxially stretched, and has improved impact resistance against drops, etc.
