【0001】 [0001]

【産業上の利用分野】本発明は、定形の外殻を形成する外層内に、変形自在な内袋を形成する内層を剥離自在に積層成形し、外観形状の変化を発生させることなく、かつ内容液収納部に外気を侵入させることなく、内容液の注出使用を可能とした合成樹脂製二層ブロー成形壜体において、外層と内層との間への空気取り入れ孔を形成する方法に関するものである。 BACKGROUND OF THE INVENTION This invention is in the outer layer that forms an outer shell of the standard sizes, the inner layer forming a deformable inner bag freely laminated molded peeled without causing a change in the external shape, and content liquid storage portion without penetration of outside air, the content liquid dispensing allows use with synthetic resin two-layer blow-molded bottle body, a method of forming an air intake hole to between the outer layer and the inner layer it is.

【0002】 [0002]

【従来の技術】定形の外殻を形成する外層内に、変形自在な内袋を形成する内層を剥離自在に積層して構成した合成樹脂製ブロー成形壜体の代表的な従来技術としては、特開平5−310265号公報に開示された技術がある。 BACKGROUND ART outer layer to form a fixed form of the shell, as a typical prior art was constructed with an inner layer forming a deformable inner bag and releasably laminated synthetic resin blow molded bottle body, there is a technique disclosed in Japanese Patent Laid-Open No. 5-310265.

【0003】この従来技術は、壜体をブロー成形する際に形成される金型喰切り部である底部パーティングラインに、内層同士は接着し、外層同士は接着しないことにより形成されるスリットを設け、内層内に収納された内容液が注出使用されて、内層が形成する内袋が容積減少変形する際に、このスリットを通して外層と内層との間に外気を侵入させることにより、外層に対する内層の剥離を円滑に達成できるようにして、内容液の注出使用による内層の容積減少変形が無理なく良好に行われるようにしている。 [0003] This prior art, the bottle body at the bottom parting line is die 喰切 Ri portion formed during the blow molding, the inner layer each other and adhere, a slit outer layer to each other are formed by not adhering provided, the content liquid that has been housed in the inner layer is used pouring, when the inner bag inner layer is formed to volume reduction deformed, by entering the outside air between the outer layer and the inner layer through the slit, for the outer layer as the peeling of the inner layer can be smoothly accomplished, so that dispensing using an inner layer of volume reduction deformation due content liquid is performed reasonably well.

【0004】 [0004]

【発明が解決しようとする課題】しかしながら、上記従来技術は、外層と内層との間への外気の侵入口であるスリットを壜体の底面に開口させているので、壜体を浴室等の湯水が位置する面上で使用すると、この壜体底面に開口されたスリットから湯水が外層と内層との間に侵入し、汚れや徴を発生し易くすると共に、壜体の持ち運び時に滴り落ちて、衣服や周囲を汚すと云う問題があった。 [SUMMARY OF THE INVENTION However, the prior art described above, since the slit is outside air intrusion port is opened in the bottom surface of the bottle to between the outer layer and the inner layer, hot water bath or the like bottle body There when used on the face positioned, the bottle body hot water from the opened slit on the bottom to penetrate between the outer layer and the inner layer, as well as liable to occur dirt and symptoms, drips when traveling with the bottle, there has been a problem that the contamination of the clothing and surroundings.

【0005】また、スリットを、壜体の脚部を形成する底部に開口形成しているので、壜体の脚部としての底部の機械的強度を低下させて、底部の自己形状保持能力を低下させることになり、これにより、特に内容液が満たされている状態では、壜体の座りが不安定になるとか、 Further, a slit, since the opening formed in the bottom to form the leg portion of the bottle body, to lower the mechanical strength of the bottom portion of the leg portion of the bottle body, reducing the self-shape-retaining capability of the bottom will be, thereby, Toka especially in the state in which the content liquid is filled, sitting in the bottle becomes unstable,
底部に衝撃を与えないように、取扱いに注意を要することになると云う問題があった。 So as not to impact the bottom, there is a problem that a would require careful handling.

【0006】そこで、本発明は、上記した従来技術における問題点を解消すべく創案されたもので、外層と内層との間への空気取り入れ孔を、壜体の口部を含めた胴部の任意の箇所に形成することを技術的課題とし、もって衛生的な使用形態を得ることができると共に、機械的強度の安定した壜体を得ることを目的とする。 [0006] The present invention has been made to solve the problems in the conventional techniques described above, to between the outer layer and the inner layer of air intake holes of the body including the mouth portion of the bottle body a technical problem to be formed at an arbitrary location, with it is possible to obtain a hygienic use forms, and to obtain a stable bottle of mechanical strength.

【0007】 [0007]

【課題を解決するための手段】上記技術的課題を解決する本発明の構成は、ブロー成形により、定形の外殻を形成する合成樹脂製の外層と、この外層に剥離自在に積層され、内袋を形成する可撓性合成樹脂製の内層とから構成される二層ブロー成形壜体に施すこと、壜体の外層を内層よりも融点の低い合成樹脂材料で形成すること、壜体の外層材料の融点以上で内層材料の融点未満の温度に加熱した穿孔治具を、壜体の口部を含めた胴部の外層部分に押し当て、この外層に内層との間への空気取り入れ孔を溶融形成すること、にある。 Configuration of the present invention to solve the above technical problems SUMMARY OF THE INVENTION may, by blow molding, a synthetic resin outer layer forming the outer shell of the shaped, is releasably laminated to the outer layer, inner applying the inner layer made of a flexible synthetic resin forming the bag into two layers blow molded bottle body formed, to form the outer layer of the bottle at a lower synthetic resin material having a melting point than the inner layer, the outer layer of the bottle the drill jig heated to a temperature below the melting point of the inner layer material of a material the melting point or more, against the outer portion of the body including the mouth portion of the bottle body, the air intake hole to between the inner layer to the outer layer melting form, in.

【0008】壜体の外層と内層との間を、縦長細帯状の接着帯により、空気取り入れ孔を避けた少なくとも一箇所で壜体の全高さ範囲にわたって接着固定するのが良い。 [0008] between the outer layer and the inner layer of the bottle body, the glue band longitudinal strip-like, had better be bonded over the entire height range of the bottle body at least one location that avoids air intake hole.

【0009】壜体の外層をポリエチレンで形成し、内層をナイロンで形成するのが、また外層をポリエチレンで形成し、内層をエチレンビニルアルコール共重合体で形成するのが好適である。 [0009] The outer layer of the bottle was formed of polyethylene, to form an inner layer of nylon, but also the outer layer is formed of polyethylene, it is preferable to form an inner layer of ethylene vinyl alcohol copolymer.

【0010】 [0010]

【作用】壜体の外層に押し当てられる穿孔治具は、外層材料の融点以上で内層材料の融点未満に加熱されているので、外層のみが溶融し、外層に空気取り入れ孔が穿設される。 [Action] drilling jig pressed against the outer layer of the bottle body, because it is heated to below the melting point of the inner layer material above the melting point of the outer layer material, only the outer layer is melted, the air intake hole is formed in the outer layer .

【0011】定形の外殻を形成する外層と、内容液を直接収納する変形自在な内袋を形成する内層とは、剥離自在に積層されており、この外層と内層との間は前記空気取り入れ孔により外部に開放されるので、内層内に減圧が発生して、内層がその内部容積を減少させる方向に変形しようとすると、外層内への空気取り入れ孔からの外気の侵入により、外層と内層との剥離が円滑に達成されて、内層の変形が無理なく良好に達成される。 [0011] an outer layer to form a fixed form of the shell, and the inner layer to form a deformable inner bag for containing liquid contents directly, are releasably laminated, between the outer layer and the inner layer incorporates the air because it is open to the outside by holes, vacuum in the inner layer occurs, the inner layer to deform in a direction to reduce its internal volume, the intrusion of outside air from the air intake hole into the outer layer, the outer layer and the inner layer peeling is smoothly accomplished with, the inner layer of the deformation is achieved reasonably good.

【0012】この際、外気は空気取り入れ孔を通して外層内に侵入し、内層だけが外層から剥離して容積を減少させる方向に変形するので、外層は変形を発生させる外力を受けることが全くなく、変形することなく定形の外殻形状を維持し、壜体の外観形状を一定に保持する。 [0012] At this time, the outside air penetrates into the outer layer through the air intake holes, because only the inner layer is deformed in a direction to reduce the release to volume from outer, the outer layer is absolutely no receiving an external force to generate a deformation, It modified maintaining the shaped shell shape without, for holding the external shape of the bottle constant.

【0013】空気取り入れ孔は、口部を含めた胴部の所望する任意の箇所に位置しているので、この空気取り入れ孔の位置を小異に設定することにより、湯水が位置する面上に壜体が置かれても、この湯水が位置する面から離れて上方に位置することになり、このためこの面上の湯水が空気取り入れ孔を通して外層と内層との間に侵入することはない。 [0013] air intake holes, because it is located in the desired arbitrary location of the body including the mouth, by setting the position of the air intake hole in the minor differences, on a surface hot water is located even the bottle is placed, will be located upwardly away from the surface the hot water is located, and therefore will not be hot water on the surface from entering between the outer layer and the inner layer through the air intake hole.

【0014】また、空気取り入れ孔は、壜体強度を劣化させる恐れのない箇所を任意に選択し、この箇所に穿設することができるので、壜体底面の金型喰切り部の外層同士を離反させることなく接合した状態のままとすることができるので、壜体の底部は、通常の合成樹脂製ブロー成形壜体の底部と同等の機械的強度に維持することになる。 Further, the air intake holes, arbitrarily select locations without degrade the the bottle strength, it is possible to bored at this point, the outer ends of mold 喰切 Ri portion of the bottle bottom surface it is possible to remain bonded without separating the bottom of the bottle body, it will maintain the mechanical strength bottom of equivalency of the conventional synthetic resin blow molded bottle body.
