〔産業上の利用分野〕
本考案は、ポリエチレンテレフタレート樹脂等
の合成樹脂製の２軸延伸ブロー成形された壜体の
構造に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a biaxial stretch blow-molded bottle made of synthetic resin such as polyethylene terephthalate resin.
ウイスキー、醤油等の液体を収納する比較的大
型の壜状容器として、合成樹脂製の壜体が広く利
用されるようになつている。
BACKGROUND OF THE INVENTION Synthetic resin bottles are becoming widely used as relatively large bottle-shaped containers for storing liquids such as whiskey and soy sauce.
この壜体の成形手段として最も有効と思われる
ものは、結晶性の合成樹脂材料で成形された一次
成形品を２軸延伸ブロー成形により壜体に成形す
る手段であり、特にポリエチレンテレフタレート
樹脂で成形された２軸延伸ブロー成形壜体は、肉
薄で軽量でありながら機械的強度および耐内容物
性に優れ、安価に大量生産が可能である等の多く
の利点を持つものであつた。 The most effective method for forming this bottle is considered to be a method in which a primary molded product made of a crystalline synthetic resin material is formed into a bottle by biaxial stretch blow molding, and in particular, molded from polyethylene terephthalate resin. The resulting biaxially stretched blow-molded bottle had many advantages, including being thin and lightweight, having excellent mechanical strength and resistance to contents, and being able to be mass-produced at low cost.
この２軸延伸ブロー成形壜体は、一般的には、
全体として丸味を帯びており、表面が円滑であ
り、さらに比較的大型であるので、滑り易く把持
し難い不都合があり、別に成形された把手を組付
ける等の取扱上の保持手段を壜体本体とは別個に
設けなければならなかつた。 This biaxially stretched blow molded bottle is generally
The overall shape of the bottle is rounded, the surface is smooth, and it is relatively large, so it is slippery and difficult to grip. It had to be established separately.
この不都合を解消すべく、壜体の筒形状をした
胴部の両側部分に縦長となつた凹部を形成するこ
とによつて、壜体の胴部の後半部分を把手代わり
に利用できるように構成した壜体が製造されるよ
うになつている。 In order to eliminate this inconvenience, by forming vertically elongated recesses on both sides of the cylindrical body of the bottle, the latter half of the body of the bottle can be used as a handle. Bottles of this type are now being manufactured.
上記した従来の壜体は、壜体の取扱は確かに便
利となるのであるが、必ずしも機械的強度の観点
からみて形状を自己保持する安定性が充分である
とは言い難いものとなつていた。
Although the conventional bottles described above are certainly convenient to handle, they are not necessarily stable enough to maintain their own shape from a mechanical strength perspective. .
すなわち、この種の壜体は、その胴部の肉厚が
充分に薄いために、内外部から作用する押圧力に
よつて比較的容易に湾曲変形するものとなり、こ
のため前記した把手部を把持して壜体全体を持ち
上げて取扱う際に、把手部に作用する指先の力に
よつて凹部底壁が容易に陥没湾曲変形してしま
い、これによつて手による壜体の把持の安定性が
失なわれると云う問題点があつた。 In other words, this type of bottle has a sufficiently thin body, so it is relatively easy to curve and deform due to pressing force applied from the inside and outside, and therefore, it is difficult to grip the handle as described above. When the entire bottle is lifted and handled, the bottom wall of the recess is easily bent and deformed by the force of the fingertips acting on the handle, which makes it difficult to hold the bottle by hand. There was a problem that it was lost.
また、把手部を形成する胴部表面は、他の胴部
表面と全く同じに極めて平滑な面となつているの
で、極めて滑り易い状態にあり、これがため前記
した把持の安定性はより低下することになつてい
た。 Furthermore, the surface of the body that forms the handle is extremely smooth, just like the other surfaces of the body, so it is extremely slippery, which further reduces the stability of the grip described above. It was becoming a thing.
さらに、凹部は筒形状をした胴部の筒壁の一部
に反転湾曲成形されたものであるので、胴部に対
する内外からの押圧力に対して最も弱い部分とな
つており、これがため、前記したごとく、外力の
作用に対しては湾曲変形し易く、内方からの押圧
力、例えば落下時に作用する内圧に対しては反転
変形し易い等の不満があつた。 Furthermore, since the concave portion is formed by inverted curve molding on a part of the cylindrical wall of the cylindrical body, it is the weakest part against the pressing force from the inside and outside of the body. As a result, there have been complaints that they tend to curve and deform when exposed to external forces, and tend to reversely deform when pressed from inside, such as internal pressure that is applied when dropped.
本考案は、上記した従来例における問題点およ
び不満を解消すべく考案されたもので、胴部に形
成された凹部に、この凹部に作用する外力である
内外圧に対抗できる補強リブを設け、もつて凹部
の機械的強度を高めると共に滑り易さを無くすこ
とを目的としたものである。 The present invention was devised to solve the problems and dissatisfaction with the conventional examples described above, and includes reinforcing ribs that can resist internal and external pressure, which is an external force acting on the recess, in the recess formed in the body. The purpose of this is to increase the mechanical strength of the concave portion and eliminate slippage.
以下、本考案を、本考案の一実施例を示す図面
を参照しながら説明する。
Hereinafter, the present invention will be explained with reference to the drawings showing one embodiment of the present invention.
本考案による２軸延伸ブロー成形壜体１は、筒
形状の胴部２の中央部両側部分を内方に陥没させ
て設けられた一対の凹部４によつて胴部２の中央
部後半部分を把手部７に形成し、この両凹部４の
平板状となつた底壁５にリブ条８を突出湾曲成形
し、このリブ条８を底壁５のほぼ全高さおよび全
幅範囲にわたつて略Ｘ字状に延出成形することに
よつて補強リブ９に成形して構成されている。 The biaxially stretched blow-molded bottle 1 according to the present invention has a pair of recesses 4 formed by recessing both sides of the central part of the cylindrical body 2 inwardly, so that the latter half of the central part of the cylindrical body 2 is recessed inwardly. A rib strip 8 is formed on the handle portion 7 and curved to protrude from the flat bottom wall 5 of both of the recesses 4, and the rib strip 8 is formed in an approximately X shape over almost the entire height and width range of the bottom wall 5. The reinforcing ribs 9 are formed by extending into a letter shape.
一対の凹部４は、胴部２の両側部分に互いに対
向位置する位置関係で形成され、もつて両凹部４
の底壁５の間隔を小さくして、もつてこの両凹部
４を形成した胴部２の後部部分を把手として利用
することができるようにしているのである。 The pair of recesses 4 are formed on both sides of the body 2 in a positional relationship that opposes each other.
By reducing the distance between the bottom walls 5 of the handle, the rear part of the body part 2 in which both the recesses 4 of the lever are formed can be used as a handle.
本考案による壜体１は、上記の如く、胴部２に
一対の凹部４が設けられ、この凹部４は、その底
壁５間の間隔が小さくなつているので、この凹部
４を設けた胴部２の後半部分は片手で持ち易い形
状となつている。
As described above, the bottle 1 according to the present invention has a pair of recesses 4 in the body 2, and the distance between the bottom walls 5 of the recesses 4 is small. The latter half of part 2 has a shape that makes it easy to hold with one hand.
また、補強リブ９は、凹部４の底壁５に、突出
湾曲成形されたリブ条８を、底壁５のほぼ全高さ
及び全幅範囲にわたつて略Ｘ字状に延出させるこ
とにより突出形成されたものであるので、内外圧
が加わり易い平板状の底壁５を、縦方向、横方
向、および斜め方向にほぼ全域にわたつて補強
し、凹部４に充分の機械的強度を持たせることが
でき、従つて凹部４に内圧或いは外圧が作用して
も、内圧の作用によつて凹部４が外方に反転湾曲
して突出変形するとか、外圧の作用によつて凹部
４が内方にさらに陥没変形するとかの変形がし難
くなる。 Further, the reinforcing ribs 9 are formed by protruding and curved rib strips 8 on the bottom wall 5 of the recess 4 and extending in a substantially X-shape over almost the entire height and width of the bottom wall 5. The flat bottom wall 5, which is easily subjected to internal and external pressure, is reinforced over almost the entire area in the vertical, horizontal, and diagonal directions, so that the recess 4 has sufficient mechanical strength. Therefore, even if internal pressure or external pressure is applied to the recess 4, the recess 4 may curve outward and protrude due to the action of the internal pressure, or the recess 4 may curve inward due to the action of the external pressure. Furthermore, deformation such as depression becomes difficult to occur.
また、補強リブ９は底壁５の略全高さ範囲およ
び全幅範囲にわたつて形成されているので、把手
部７を把持した手の指先は、必ずこの補強リブ９
のいづれかの部分に対向することになり、このた
め指先の補強リブ９に対する引掛りによつて手に
よる壜体の取扱いは滑り難いものとなる。 Furthermore, since the reinforcing ribs 9 are formed over substantially the entire height range and the entire width range of the bottom wall 5, the fingertips of the hand gripping the handle 7 are sure to touch the reinforcing ribs 9.
Therefore, since the fingertips are caught on the reinforcing ribs 9, handling of the bottle by hand becomes difficult.
この場合、補強リブ９はＸ字状となつているの
で、補強リブ９に対する引掛りは、必ず下方から
引掛り力を含むことになり、これによつて指先の
補強リブ９に対する引掛り形態に考慮を払うこと
なく、必然的に指先の補強リブ９に対する良好な
引掛りを達成できることになる。 In this case, since the reinforcing ribs 9 are X-shaped, the hooking on the reinforcing ribs 9 will necessarily include a hooking force from below, and this will change the way the fingertips are hooked on the reinforcing ribs 9. Without this consideration, it is possible to naturally achieve good engagement of the fingertips with the reinforcing ribs 9.
図示実施例の場合、壜体１はほぼ四角筒形状の
胴部２を有していて、この胴部２の上端に肩部を
介して口筒３が立設して構成されている。
In the case of the illustrated embodiment, the bottle 1 has a body 2 having a substantially rectangular cylindrical shape, and a spout 3 is erected from the upper end of the body 2 via a shoulder.
胴部２の両側部分に設けられた凹部４は、その
中央部分である平板状の底壁５に向かつて傾斜し
たテーパー壁６によつて陥没形成され、胴部２の
後部に把手部７が形成されている。 The concave portions 4 provided on both sides of the body portion 2 are depressed by tapered walls 6 that are inclined toward the flat bottom wall 5 that is the central portion, and a handle portion 7 is formed at the rear of the body portion 2. It is formed.
また、図示実施例の場合、補強リブ９はアルフ
アベツトの大文字筆記体におけるＸ字状となつて
いて、より多くの凹凸を形成して、底壁５に加え
られる圧力に対抗できるようにしてあり、さらに
Ｘ字における上部、下部、および把手部７側の後
部にも、補強リブ９に沿つて突出湾曲成形された
リブ条８が設けられていて、底壁５の補強を助長
している。 Further, in the case of the illustrated embodiment, the reinforcing rib 9 has an X-shape in alphabetical upper case cursive, and has more unevenness so as to be able to resist the pressure applied to the bottom wall 5. Further, rib strips 8 which are curved and protruded along the reinforcing ribs 9 are provided at the upper and lower portions of the X-shape and at the rear portion on the side of the handle 7 to help reinforce the bottom wall 5.
なお、Ｘ字状の補強リブ９の前部にリブ条８を
設けなかつたのは、把手部７を把持した際に指が
位置する部分を確保し、補強リブ９に指を係止さ
せてより高い滑り止め効果をも発揮させて、持ち
易くするためである。 The reason why the rib strip 8 is not provided on the front part of the X-shaped reinforcing rib 9 is to secure the part where the fingers will be placed when gripping the handle part 7, and to allow the reinforcing rib 9 to hold the fingers. This is to provide a higher anti-slip effect and make it easier to hold.

As is clear from the above description, the biaxially stretched blow-molded bottle of the present invention can be held and handled stably and well, and is resistant to handling such as being dropped while filled with liquid. Therefore, if there is a shocking increase in internal pressure inside the bottle and a strong internal pressure acts on the recess, or because the handle is filled with liquid and is heavy, a strong external pressure may be applied to the recess. When this happens, the reinforcing ribs counteract the internal and external pressures that act on the recesses, so the recesses do not curve outward or inward, thereby significantly increasing the mechanical strength of the entire bottle. Furthermore, since the handle remains integrally molded with the bottle, it is easy to handle relatively large bottles, and the reinforcing ribs have a simple structure, making molding the bottle less troublesome. It exhibits many excellent effects, such as being able to achieve the same results as before without causing any problems.
