Definitions
- the present invention relates to a synthetic resin casing that is formed thin so that volume reduction deformation progresses as the internal pressure is reduced.
- the present invention also relates to a combination of a continuous use container and a refill container used for detergents, softeners, bleaches, bathing agents, foods, cosmetics, medicines and the like.
- continuous use containers Containers that are usually used for storing liquids and that have a measuring function part attached to the outlet of a relatively thick container body (hereinafter referred to as “continuous use containers”) shall be used continuously and supplemented. Store the liquid in an inexpensive refill container and transfer it to a continuous use container.
- refill containers conventionally, as this type of refill container, a so-called pouch container, which is formed into a bag shape by overlapping flexible sheet pieces, as described in Patent Document 1, for example, is often used. ing.
- the pouch container described in Patent Document 1 is provided with a nozzle receiving portion serving as a spout, and this nozzle receiving portion is externally fitted to the pouring nozzle of the continuous use container to transfer the content liquid. Since the content liquid is refilled through the nozzle receiving portion and the dispensing nozzle, it is possible to suppress the liquid splash and liquid sag of the content liquid.
- Patent Document 2 describes a configuration relating to a method of combining a continuous use container and a refill container for eliminating the above-described content splash and liquid sag.
- the basic structure related to this coupling method is that a transition cap from which a tubular nozzle protrudes is disposed at the opening of the container body of the continuous use container, while the inner lid is disposed at the opening of the refill container via the weakening portion. Assemble and fix the fit joint with the fitting, and in use, fit the transition cap and the fit joint in a liquid-tight manner, and with this fitting operation, the nozzle that protrudes from the transition cap is placed on the fit joint The inner lid is pushed open.
- the inner lid is opened with the phytojoint of the refilling container attached in a liquid-tight manner to the transition cap of the container for continuous use. There is no sagging, and the refill container is assembled and held in an inverted position with respect to the container for continuous use, so there is no need to hold the refill container with hands.
- the pouch container of the above-mentioned Patent Document 1 it is possible to maintain the inverted posture for the time being by attaching the nozzle receiving portion to the pouring nozzle of the continuous use container.
- the volume of the pouch container is reduced and deformed in a flat shape, so it is difficult to stably maintain the inverted posture, and the flat portion is bent and lost its balance.
- the container may fall over with the continuous use container, and it is necessary to support it by hand while monitoring or during refilling, and it is difficult to say that it is easy to use.
- the inner lid pushed open by the nozzle has a simple flat plate structure, and therefore is positioned so as to almost block the upper end opening of the nozzle pushing up the inner lid. So, for this reason, the upper end opening of the nozzle is almost blocked by the inner lid, so that the liquid content flows through both sides of the nozzle, but this passage is the “escape” of air from the continuous use container to the refill container. Since it also serves as a passage, there is a problem that the refilling of the content liquid cannot be achieved smoothly.
- the present invention relates to a synthetic resin casing formed into a thin wall by blow molding, and intends to solve the problems associated with the above-described conventional refill containers, and its technical problem is to stabilize the casing as a casing.
- the object is to create a housing shape that can smoothly advance the volumetric deformation of the peripheral wall due to internal decompression while maintaining a proper posture.
- the present invention also relates to a combination of a continuous use container and a refill container having a stand-up pouring cylinder piece, and obtaining a preferable disposal state of the refill container while obtaining a stable refill operation of the contents liquid. Therefore, it is an object of the present invention to refill the content liquid satisfactorily and to obtain a good disposal of the refill container after refilling.
- the present invention relates to a combination of a synthetic resin casing and a continuous use container and a refill container.
- the synthetic resin casing of the present invention will be described, and then a combination of a continuous use container and a refill container will be described.
- the main structure of the synthetic resin casing of the present invention is: In a synthetic resin casing by blow molding having a mouth cylinder part, a tapered cylindrical shoulder part, a cylindrical trunk part and a bottom part, The peripheral wall of the torso is formed into a thin wall that can undergo volumetric deformation as the pressure inside the housing is reduced.
- this peripheral wall has three ridge lines that are formed in a mountain fold shape at substantially equal intervals in the vertical direction, and the adjacent ridge lines are connected by three panel walls.
- Each panel wall is formed with a fold-like crease line that connects the upper end of one ridge line and the lower end of the other ridge line in a diagonal manner, and the three crease lines are inclined in parallel in the circumferential direction. Constitute, It is said.
- the peripheral wall of the body part into a thin wall that can proceed with volume reduction deformation as the pressure inside the housing is reduced, a pressing force or a twisting force is applied to the housing from the outside. Without reducing pressure inside the housing, the housing can spontaneously reduce and deform due to the pressure difference between the inside and outside, and the formation of ridge lines and crease lines stabilizes this spontaneous volume reduction deformation. This is a requirement for smooth progress while maintaining a proper posture.
- the casing filled with the content liquid is almost in an inverted position with the mouth tube part fixed, and the outside air is allowed to enter inside.
- a certain amount of content liquid can be poured out from the mouth tube portion by its own weight.
- the shoulder and the bottom are maintained in the original shape, and a valley-folded fold line is formed which is formed relatively thin and serves as a starting point for the depression deformation.
- the peripheral wall of the body part is deformed in a twisted manner, and as a result, the body part is reduced in the height direction, and the inverted posture is substantially straightened from the initial shape by the twisted deformation of the body part and the reduction in the height direction. It is possible to advance the volume reduction deformation of the housing while holding it. For this reason, since there is no worry of the container falling down due to pouring unlike a pouch container, there is no need to support it by hand, and the refilling operation can be performed with peace of mind.

- the outer shape of the flat cross section of the peripheral wall is held in a regular triangle shape, and the function of stably maintaining the inverted posture of the housing even in the reduced volume deformation state is exhibited.
- each ridge line is displaced in an inclined manner according to the progress of the depression deformation of the panel wall along the crease line, while maintaining a substantially initial distance with respect to the central axis as described above.

It is said to be in the range.
- the above configuration relates to the inclination angle of the crease line formed on the panel wall, and setting the distance / height value in the range of 0.6 to 1.7 means that the ridge line formed in the vertical direction This is equivalent to setting the inclination angle of the crease line to approximately 30 ° to 60 °.
- the inclination angle within this range, the torsional deformation of the trunk and the accompanying reduction in the height direction are sufficiently advanced.
- the volume-reducing deformation can be smoothly advanced while maintaining the inverted posture of the housing substantially straight.
- the inclination angle is too small, that is, if the crease line is oriented in the longitudinal direction, the twist angle in the torsional deformation can be increased, but the three crease lines come into contact with each other.
- the reduction in the height direction is insufficient.
- the tilt angle is too large, that is, if the crease line is oriented in the lateral direction, the torsion angle in the torsional deformation cannot be increased, and in this case, the reduction in the height direction is insufficient.
- Still another configuration relating to the synthetic resin casing of the present invention is that the shoulder portion has a hemispherical shell shape and the bottom portion has a bottomed short cylindrical shape in the above main configuration.
- the shoulder part has a hemispherical shell shape, and the bottom part has a bottomed short cylindrical shape.
- the volume reduction deformation can be progressed more smoothly while maintaining the inverted posture of the housing substantially straight.
- Still another configuration relating to the synthetic resin casing according to the present invention is such that, in the main configuration, three ridge lines are extended to the side peripheral wall of the bottom portion, and the bottom portion is formed into a bottomed short triangular cylindrical shape by the three ridge lines. It is said to be.

Since it progresses, the combination of a continuous use container and a refill container can maintain the stable self-supporting state, advancing the volume reduction deformation of a housing.
- the flow channel area of the extraction passage formed by opening the inner plug in the main configuration is set to such an extent that the content liquid breathes and flows. It is said that the whole amount of the content liquid can be poured out by natural flow due to its own weight.
- the body of the housing is reduced. Due to the resistance caused by the deformation, the dispensing of the content liquid automatically stops once due to its own weight, but the aspect related to the subsequent dispensing operation is the flow of the dispensing path formed by opening the inner plug. Depending on the road area, it can be roughly divided into two modes.
- the above configuration relates to one aspect related to the dispensing operation, and the flow area is relatively large, and outside air is raised into the enclosure in the form of bubbles from an opening formed by opening the inner plug. In this manner, the content liquid is continuously poured out in the form of a breath, and this makes it possible to complete the refilling of the entire content liquid by the natural flow of the content liquid due to its own weight without touching it.
- the refilling of the contents liquid is completed as the refill container is reduced in volume due to the natural flow of the contents liquid, so when the refilling of the contents liquid is completed, the barrel of the refill container is reduced.

- the above-described configuration relates to another aspect relating to the dispensing operation after the natural flow due to the weight of the content liquid has been automatically stopped once due to the resistance generated with the volume reduction deformation of the body of the casing.
- the refilling operation that is, the refilling of the content liquid, can be completed in a short time.
- the refilling of the contents liquid is completed by pouring out by forced crushing of the casing, so when the refilling of the contents liquid is completed, the casing of the refilling container is completely vertical. Therefore, when the refill container is removed from the continuous use container and discarded, it can be discarded as it is. In other words, the content liquid can be poured out and the volume of the refill container can be reduced simultaneously by forced crushing.
- Still another configuration relating to the “combination of containers” according to the present invention is that the inner plug is provided at the tip of the fitting cylinder in the main configuration described above.

- the opening swing direction of the inner stopper can be regulated to be constant, so that the opening and tilting operation of the inner stopper is constant and stable. can do.
- the present invention has the above-described configuration, the following effects can be obtained. That is, in the synthetic resin casing having the main configuration of the present invention, Assuming that it will be used as a refill container, as the contents of liquid are being poured out, the shoulder and bottom will retain their original shape, but will be relatively thin and will be the starting point for the deformation.
- the body wall where the crease line is formed deforms in a torsional shape and shrinks in the height direction, while maintaining the inverted posture from the initial shape substantially straight, while the volume reduction deformation of the housing proceeds . For this reason, since there is no worry of the container falling down due to pouring unlike a pouch container, there is no need to support it by hand, and the refilling operation can be performed with peace of mind.
- the volume reduction deformation of the enclosure due to the natural flow due to the weight of the refilling content liquid stably maintains the assembly of the refill container in the inverted state with respect to the continuous use container.
- the self-supporting function of the combination of the replacement containers is stably maintained, so that refilling of the content liquid can be stably achieved without touching.
- the case where the content liquid has been poured out is in a state where its body has been deformed and deformed to some extent, by applying a crushing force to the case in the vertical direction, The volume can be reduced and deformed in a crushed shape in the vertical direction easily, whereby the disposal of the housing can be carried out suitably and efficiently.
- the outside air is raised into the enclosure in the form of bubbles from the opening, and the content liquid is continuously discharged in the form of a breath.
- the refilling of the entire amount of the content liquid can be completed by natural flow due to the weight of the content liquid without adding a hand.
- the flow area is relatively small so that outside air does not rise in the form of bubbles from the opening formed by opening the inner plug
- the refilling of the content liquid can be completed by forcing the remaining content liquid forcibly by crushing the casing that has been deformed to a certain extent from above, and clogging the content liquid.
- the change can be completed in a short time.
- the push-up piece has a part that pushes and opens the inner plug and a part that holds the inner plug in the release posture
- the push-up piece is pushed up by the part that the push-up piece opens. Since the tilted and opened inner plug is continuously held by the portion that holds the opened posture, the flow passage area of the formed extraction passage can be stably and constantly held.

Abstract
Description
普段内容液を収納して使用する、比較的厚肉な容器本体の注出口に計量機能部を付帯させる等した容器(以下、継続使用容器とする。)は継続使用するものとし、補充する内容液は安価な詰替え容器に収納し、継続使用容器に移し替えて使用する。
この結合方法に係る基本的な構成は、継続使用容器の容器本体の開口部に管状のノズルが突出するトランジッションキャップを配設し、一方、詰替え容器の開口部に弱化部を介して内蓋を配設したフィットジョイントを組付け固定し、使用時にはトランジッションキャップとフィットジョイントを液密状に嵌合すると共に、この嵌合操作に伴って、トランジッションキャップに突出するノズルでフィットジョイントに配設される内蓋を押し開く、と云うものである。
このためノズルの上端開口部が内蓋により殆ど塞がれるので、内容液はノズルの両側を通って流動することになるが、この通路は継続使用容器から詰替え容器への空気の「逃げ」通路ともなるため、内容液の詰替えがスムーズに達成されない、と云う問題がある。
口筒部とテーパー筒状の肩部と筒状の胴部と底部を有するブロー成形による合成樹脂製壜体において、
胴部の周壁は壜体内部の減圧化に伴って減容変形が進行可能な薄肉に形成され、
また、この周壁は、山折状に縦方向に略等間隔に形成される3本の稜線を有し、隣接する稜線を3ケのパネル壁で連結した構成であり、
各パネル壁には一方の稜線の上端部と他方の稜線の下端部を対角線状に連結する谷折状の折り目線を形成し、3本の折れ目線が周方向に並列状に傾斜するように構成する、
と云うものである。
このため、パウチ容器のように注出に伴う容器の横倒れの心配もないので、手で支えてやる必要もなく、安心して詰替え操作を実施することができる。
内容液の注出に伴って、内部と外部の圧力差により壜体の周壁全体に押圧力が作用するが、胴部の周壁の各パネル壁に傾斜状に谷折り状、すなわち陥没状に形成される3本の折り目線が、壜体の中心軸に近づくように変位して減容変形が進行する。この際、各パネル壁は折り目線を起点として、折り目線に沿って折り畳まれるようにして陥没状に変形する。
この際、各稜線は上記のように中心軸に対して略初期の距離を保持しながら、折り目線に沿ったパネル壁の陥没変形の進行に従って傾斜状に変位する。
そしてその結果、前述したように胴部の周壁が捩れ状に変形すると共に胴部が高さ方向に縮小する。
なお、周壁の肉厚の下限値については壜体の自立性等の点から適宜設定することができる。
ここで、この傾斜角度が小さすぎると、すなわち折れ目線が縦方向に向きすぎると、捩れ状の変形における捩れ角度を大きくすることはできるが、3本の折れ目線が相互に当接し、その結果高さ方向の縮小が不十分となる。
一方、傾斜角度が大きすぎると、すなわち折れ目線が横方向に向きすぎると、捩れ状の変形における捩れ角度を大きくすることができず、この場合も高さ方向の縮小が不十分となる。
本発明の「容器の組合せ」に関する構成はいずれも詰替え容器に上記説明した本発明の壜体を使用するものであり、
その主たる構成は、
容器本体の口筒に、起立して注出通路を形成する注出筒片を有する本体キャップを組付けた継続使用容器と、詰替え用の内容液を収納する壜体の口筒部に、結合蓋を組付けた詰替え容器の組合せであり、
壜体の胴部は、内容液が自然流下する注出による内部の減圧化に伴って、減容変形可能な薄肉に形成され、
詰替え容器の結合蓋に、継続使用容器の注出筒片に嵌入組付きする嵌合筒を設け、この嵌合筒を塞ぐ中栓を設け、
嵌入組付けされた嵌合筒の中栓を押上げて開放する押上げ体を、継続使用容器の注出筒片に設け、
詰替え容器の継続使用容器への組付けにより内容液の詰替えを可能とする、
と云うものである。
上記構成は、この注出操作に係る態様の一つに関するものであり、流路面積を比較的大きくし、中栓を開放して形成される開口から外気を気泡状に壜体内に上昇させて、息つき状に内容液の注出を継続させるものであり、これにより、手を添えることなく、内容液の自重による自然流下により内容液の全量の詰替えを完了させることが可能となる。
中栓を開放して形成される注出路の流路面積を、内容液の息つき流下が生じない程度に設定し、壜体の底部に対する押下げにより残った内容液を強制的に注出させる構成とする、と云うものである。
つまり、強制的な押し潰しにより、内容液の注出と詰替え容器の減容化を同時に行うことが可能である。
すなわち、本発明の主たる構成を有する合成樹脂製壜体にあっては、
詰替え容器として利用することを想定すると、内容液の注出の進行に伴って、肩部や底部はほぼ元の形状を保持しながら、比較的薄肉に形成され陥没変形の起点となる谷折り状の折れ目線が形成された胴部の周壁が捩れ状に変形すると共に高さ方向に縮小しながら、初期の形状からその倒立姿勢を略真直ぐに保持しつつ壜体の減容変形が進行する。
このため、パウチ容器のように注出に伴う容器の横倒れの心配もないので、手で支えてやる必要もなく、安心して詰替え操作を実施することができる。
詰替え用の内容液の自重による自然流下に伴う壜体の減容変形は、継続使用容器に対する詰替え容器の倒立状態での組付きが安定的に維持されているので、継続使用容器と詰替え容器の組合せ物の自立機能が安定して維持され、これにより手を添えることなく、内容液の詰替えを安定して達成することができる。
図1~7は本発明の壜体の第1実施例を示すものであり、図1は正面図、図2(a)は側面図、図2(b)は背面図(図2では口筒部を図示省略している)、図3は平面図、図4は底面図、図5は図1中のA-A線に沿った平断面図、そして図6と図7は減容変形の態様を示す斜視図と平面図である。
この壜体1はポリプロピレン樹脂製の2軸延伸ブロー成形品であり、口筒部2、半球殻状でテーパー筒状の肩部3、筒状の胴部4、有底短円筒状の底部5を有し、全高さ125mm、横幅70mmで、容量300mlの壜体である。
そして、底部5の側周壁5sは短円筒状で、底面の中央部には底面壁を壜体の内部方向に陥没させて陥没部5aが形成されており、その周縁にはリング状の周縁部5pが配設されている。
また、各パネル壁11には一方の側端に位置する稜線12の上端部と他方の側端に位置する稜線12の下端部を対角線状に連結する谷折状の折り目線13(13ab、13bc、13ca)を形成し、これら3本の折れ目線13が周方向に並列状に傾斜するようにしている(図1、2では右斜め上から左斜め下に傾斜している。)。
なお、変形の態様がわかり易いように、各図面では稜線12を、12a、12b、12cと云うように3本の稜線が区別できるように示し、図面間で相互に対応が取れるようにした。パネル壁11と折り目線13についても同様である。
また、本実施例の壜体1では、図1に見られるように、隣接する稜線12間の距離Lと稜線13の高さHの比である、L/Hの値は略1であり、折り目線13の中心軸Axに対する傾斜角度Dを約45°程度としている。この傾斜角度は、壜体の形状や、内容液のスムーズな注出性に係る胴部4の周壁の減容変形の態様を考慮して適宜に決めることができるものであるが、L/Hの値は0.6~1.7の範囲(中心軸Axに対する傾斜角度Dでは30°~60°の範囲)とするのが好ましい。
底部5の形状をさらに詳述すると、胴部4に形成される3本の稜線12a、12b、12cを底部5の側周壁5sにまで延設し、この3本の稜線12を図9の平断面図に示されるのと同様に円弧状に連結して側周壁5sを3角筒状とし、底部5を有底短3角筒状としている。
図8~10に示される第2実施例の壜体1は、底部6の形状を予め3角形状とすることにより、図7に示されるような捻り変形をスムーズに進行させ、壜体1の減容変形をよりスムーズに進行させるようにしたものである。
なお、第1実施例の壜体1では底部5の形状を図4に示されるように円形状とし、第2実施例の壜体1では図10に示されるように3角形状としたが、底部5の形状は特に限定されるものではなく、さらに多角形状とすることもでき、外観デザインや、減容変形時の壜体の、姿勢の保持性や捩れ変形性を考慮して適宜選択することができる。
この第1の実施形態例は、中栓を開放して形成される注出路の流路面積を内容液の息つき流下が生じる程度に比較的大きく設定し、内容液の自重による自然流下により内容液の全量が注出可能に構成したものである。
詰替え容器Aは壜体1と壜体1の口筒部2に装着される結合蓋20から構成されている。
なお、結合蓋20の口筒部2への組付きは螺合に限るものではなく、アンダーカットでも良い。
正立姿勢にある継続使用容器Bの本体キャップ40の注出筒片44に、倒立姿勢にした詰替え容器Aの嵌合筒22を嵌入組付け(図12参照)して行く。
概略的にみると、壜体1からの内容液の注出の進行に伴って、図6、7、13に示されるように、肩部3や底部5はほぼ元の形状を保持しながら、比較的薄肉に形成され、陥没変形の起点となる折り目線13が形成された胴部4の周壁が捩れ状に変形すると共に高さ方向に縮小しながら、図13中二点鎖線で示した初期の形状からその倒立姿勢を略真直ぐに保持しつつ壜体1の減容変形が進行する。
ここで、底部5は、壜体の中心軸Ax回りに口筒部2に対して相対的に回動変位する(図6、7中の白抜き矢印参照)と共に下降変位する。
また、壜体1の初期の形状では図3、4に示されるように肩部3の下端部及び底部5の平面形状は円形であるが、図7の状態では捻り変形に伴う力が作用して、それぞれが3本の稜線12の上端を頂点とした3角形あるいは下端を頂点とした3角形に近い形状に変化している。
この3角形状は、4角形状やさらなる多角形状に比較して横方向の力が作用しても扁平に変形し難く、壜体1の倒立姿勢を安定して保持することが可能となる。
内部の減圧化が進行すると、壜体1の周壁全体に押圧力が作用するが、肩部3は半球殻状で底部5は胴部4に比較して厚肉であるので、胴部4を構成する比較的薄肉で陥没変形の起点となる谷折り状の折れ目線13が形成された各パネル壁11の陥没変形が進行する。
このように胴部4の縦方向に縮小した減容変形が進行すると、胴部4の周壁の折畳み変形部分同士の突き当たりや、壜体1内の減圧度の上昇により内容液Nの自重による自然注出は一旦停止する。
図16に示されるようにこの押上げ体48は、押上げ部分49aと保持部分49bとから成る押上げ片49と、押上げ片49を起立設した梁片50と、組付きリング51とから構成されており、組付きリング51を、注出筒片44の内周面に設けた係合リブ47に係合させることにより、注出筒片44に対する押上げ体48の組付けを達成している。
この第2の実施形態例は、先に説明した第1の実施形態例と比較すると、他の部材の構成は同様にして、押上げ体48の形状を変更し、中栓を開放して形成される開口Kの大きさを制限し、注出路の流路面積を第1の実施形態例の場合よりも小さくなるように設定して内容液の息つき流下が生じない程度に構成したものである。
ここで、本実施の形態例では中栓24を開放して形成される注出路の流路面積が、内容液Nの息つき流下を生じさせない程度の値に設定しており、すなわち開口Kの大きさを制限しておりこの停止状態が持続される。
図20と図21は開口Kの大きさを押上げ体48を利用して制限する構成の例を示すもので、図20で示される構成では押上げ体48を一対の押上げ片49(押上げ部分49aと保持部分49b)と、押上げ片49を起立設した梁片50と、組付きリング51とから構成し、組付きリング51を注出筒片44の内周面に設けた係合リブ47に係合させることにより注出筒片44に対する押上げ体48の組付けを達成している。
また、図20、21に図示した実施例では押上げ体48と注出筒片44を別体にして組付ける構成としているが、押上げ体48を注出筒片44に一体成形する構成とすることもできる。
たとえば、壜体の容量は300ml程度のものに限定されるものではないし、ポリプロピレン樹脂製の2軸延伸ブロー成形の壜体に限らず、PET樹脂製の2軸延伸ブロー成形壜体、あるいはポリエチレン樹脂製のダイレクトブロー成形壜体と、さまざまな樹脂製のブロー成形品を使用することができる。
また、上記実施例では壜体を詰替え容器として利用する例を説明したが、本発明の壜体は前述したように使用後は高さ方向に十分に押し潰して、その押し潰し形状を維持した状態で廃棄可能なものであり、省資源、易廃棄性と云う特徴を生かして壜体単体としても使用することができる。
また本発明の継続使用容器と詰替え容器の組合せは、詰替え時における内容液の液跳ねや液ダレを確実に防ぐことができ、手を添えることなく内容液をスムーズに流下させて詰替えを容易に達成でき、さらに詰替えを終えた詰替え容器の十分な減容化を簡単にかつ安定的に達成することができるものであり、幅広い利用展開が期待される。
