Description

本発明は、詰替え用受液栓を利用して容器の胴部を強制的に押し潰して内容物の詰替えを行う場合において起こりがちであった受液栓の空気置換口からの液の溢れ出しを回避しつつ内容物のスムーズな移し替えを実現しようとするものである。   The present invention uses a refill receiving stopper to forcibly crush the body of the container to refill the contents, and the liquid from the air replacement port of the receiving stopper tends to occur. It is intended to achieve smooth transfer of contents while avoiding overflow.

シャンプーやリンス、洗剤、消臭除菌剤あるいは化粧品等を入れる容器としては、内容物の適量取り出しを可能とするためにポンプの如き吐出器を備えられたものが数多く上市される傾向にあり、内容物を使いきったのちは、別途に市販されている詰替え容器から新たな内容物を移し替えて詰替えるべき容器（以下、この容器を以下、継続使用容器という。）を再利用するのが普通になってきており、これによって資源の有効活用が図られている（例えば、特許文献１参照）。   As containers for shampoos, rinses, detergents, deodorizers, cosmetics, etc., many products equipped with a discharge device such as a pump tend to be put on the market in order to make it possible to take out an appropriate amount of contents. After using up the contents, re-use the containers that should be refilled by transferring new contents from the refill containers that are sold separately (hereinafter referred to as “continuous use containers”). As a result, resources are effectively utilized (see, for example, Patent Document 1).

ところで、詰替え容器はもともと、パウチタイプの容器や薄肉のブロー成形品等腰がない（剛性が低い）容器が適用されており内容物の詰替えが行い難く、例えば特許文献１のように２つの容器をねじを介して連結したのち内容物の移し替えを行うなど、これまでに種々の提案がなされてきているものの、とくに詰替え容器（薄肉容器）に注出筒を設けてこの注出筒を継続使用容器の口部に設置した受液栓に連係させて詰替えを行うものにあっては、容器の強制的な押し潰しにより内容物が一度に大量に注出された場合に受液栓の空気置換口内でバブリング現象が起こって液が溢れでてしまう不具合があり、この点に関しては未だ改善の余地が残されていた。   By the way, the refill container is originally a pouch-type container or a thin-walled blow molded product such as a low-strength (low rigidity) container, and it is difficult to refill the contents. Various proposals have been made so far, such as transferring the contents after connecting two containers via screws, but in particular, this is done by providing a pour cylinder in the refill container (thin container). In the case of refilling by linking a cylinder to a liquid stopper installed at the mouth of a container for continuous use, if the contents are poured out at a time by forced crushing of the container, it will be received. There was a problem that the bubbling phenomenon occurred in the air replacement port of the liquid stopper and the liquid overflowed, and there was still room for improvement in this regard.

特開２０００−１５９２４９号公報JP 2000-159249 A

本発明の課題は、薄肉容器を詰替え容器として内容物の詰め替えを行う場合に生じていた空気置換口からの液の溢れ出しを回避することができる新規な受液栓を提案するところにある。   An object of the present invention is to propose a novel liquid receiving stopper capable of avoiding the overflow of liquid from the air replacement port that has occurred when refilling the contents using a thin-walled container as a refill container. .

本発明は、詰替えるべき容器の口部に装着され、詰替え容器の円筒状の注出筒に連係させて該詰替え容器内の内容物を前記注出筒の内部通路を通して移し替える詰替え用受液栓であって、
前記詰替えるべき容器の口部において区画凹所を形成するベースと、このベースの底壁にて起立するとともに前記詰替え容器の注出筒がその内側に倒立姿勢で軸方向から入れ込まれて係合可能なＣ型断面形状をなす注入筒と、貫通孔を備えたリングと該リングから起立する棒体とを備えて前記注入筒の内部通路に該内部通路に形成されたフランジにおいて固定保持される開封部材とを備え、
前記注入筒の前記開封部材が固定保持された部分の垂直断面における流路面積と、前記注出筒の内部通路の垂直断面における流路面積との比が０.８６以下であり、
前記注入筒の壁部と前記ベースの壁部に、各壁部との相互間において連続的又は断続的につながり、前記注入筒の内側に係合した前記注出筒の先端が前記リングに当接した状態において、前記注出筒の内部通路の垂直断面における流路面積の１３２〜１７９％の開口面積にて開口する空気置換口を設けた、ことを特徴とする詰替え用受液栓である。 The present invention relates to a refill which is attached to the mouth of a container to be refilled and which moves the contents in the refill container through the internal passage of the refill container in association with a cylindrical dispensing tube of the refill container. A liquid receiving tap,
A base that forms a compartment recess in the mouth portion of the container to be refilled, and a pour cylinder of the refill container that is standing upright at the bottom wall of the base and is inserted into the inside thereof in an inverted posture from the axial direction. An injection cylinder having a C-shaped cross section that can be engaged, a ring having a through hole, and a rod body standing from the ring, and fixed to a flange formed in the internal passage in the internal passage of the injection cylinder An opening member to be provided,
Wherein a flow passage area the unsealing member of the injection tube is in the vertical cross section of the fixed holding portion, and the ratio of the flow channel area of 0.86 or less in the vertical cross-section of the inner passage of the pouring cylinder,
The wall of the injection tube and the wall of the base are connected continuously or intermittently between the wall portions, and the tip of the pouring tube engaged with the inside of the injection tube contacts the ring. A refill receiving tap characterized by having an air replacement port that opens at an opening area of 132 to 179% of a flow path area in a vertical section of an internal passage of the dispensing cylinder in a state of contact. is there.

詰替え容器としては、該容器を反転して内容物を自然に落下させて継続使用容器に移し替える置換タイプと、容器の胴部を加圧して内容物を強制的に継続使用容器へ移し替える強制排出タイプがあるが、本発明では、注入筒につき注出筒の内部通路の流路面積との比が０.８６以下となる流路面積を有するものにおいて、注入筒の壁部とベースの壁部に、各壁部との相互間において連続的あるいは断続的につながり、前記注出筒の内部通路における流路面積の１３２〜１７９％の開口面積を有する空気置換口を成形したため、容器の胴部を押し潰して内容物の詰替えを行う場合においても内容物がスムーズに流れ落ち、空気置換口内でバルリング現象が起きて液が溢れ出すことはない。また、内容物を詰替えた継続使用容器から内容物を排出する際、空気置換口から内容物が流れ出る（液だれ）こともないので使い勝手が改善される。   As a refill container, a replacement type that inverts the container and naturally drops the contents and transfers them to the continuous use container, and pressurizes the body of the container to forcibly transfer the contents to the continuous use container. Although there is a forced discharge type, in the present invention, in the case where the ratio of the injection cylinder to the flow area of the internal passage of the injection cylinder is 0.86 or less, the wall of the injection cylinder and the base Since the wall portion is connected to each wall portion continuously or intermittently, and an air replacement port having an opening area of 132 to 179% of the flow passage area in the internal passage of the extraction tube is formed. Even when the body is crushed and the contents are refilled, the contents flow smoothly and no bubble overflow occurs in the air replacement port and the liquid does not overflow. Further, when the contents are discharged from the continuously used container whose contents have been refilled, the contents do not flow out from the air replacement port (drip), so that the usability is improved.

以下、図面を参照して本発明をより具体的に説明する。
図１（ａ）〜（ｃ）は、本発明にしたがう詰替え用受液栓の実施の形態を模式的に示した図である。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
Fig.1 (a)-(c) is the figure which showed typically embodiment of the liquid-receiving tap for refilling according to this invention.

図における符号１は、アンダーカットの如き係合手段でもって回動不能に継続使用容器の口頚部に固定することができるベースである。このベース１は、口頚部の周りを取り囲む外周壁１ａと、この周壁１ａの上端部で一体連結し外周壁１ａと協働して下向きに開放された溝部を形成する内周壁１ｂと、この内周壁１ｂの下端に一体連結して口頚部において区画凹所を形成する底壁１ｃから構成されている。   Reference numeral 1 in the figure is a base that can be fixed to the mouth and neck of the container for continuous use so that it cannot be rotated by an engaging means such as an undercut. The base 1 includes an outer peripheral wall 1a that surrounds the mouth and neck, an inner peripheral wall 1b that is integrally connected at the upper end of the peripheral wall 1a, and forms a groove that opens downward in cooperation with the outer peripheral wall 1a. The bottom wall 1c is integrally connected to the lower end of the peripheral wall 1b and forms a partition recess in the mouth and neck.

２は、ベース１の底壁１ｃにおいて起立するＣ型断面形状をなす注入筒である。この注入筒２は、後述の副流路が設けられている側でその全長にわたって壁部に幅Wでもって切欠部２ａが設けられていて、詰替え容器の注出筒の内部通路の流路面積との比（注入筒の流路面積／注出筒の流路面積）が０.８６以下となる流路面積を有し、その先端部（上端部）が後に図示する詰替え容器の注出筒と係合するようになっており、この注入筒２を通して詰替え容器内の内容物が継続使用容器に移し替えられる。   Reference numeral 2 denotes an injection cylinder having a C-shaped cross section standing on the bottom wall 1 c of the base 1. The injection cylinder 2 is provided with a notch 2a with a width W on the wall along the entire length on the side where a sub-flow path, which will be described later, is provided. The ratio of the area (flow area of the injection cylinder / flow area of the extraction cylinder) has a flow area of 0.86 or less, and the tip (upper end) of the refill container shown later is poured. The contents in the refill container are transferred to the continuous use container through the injection cylinder 2.

また、３は、注入筒２の内部通路に設けられた開封部材である。この開封部材３は、注入筒２の内部通路に形成されたフランジｆにおいて固定保持され、十字アームにより扇形の４つの貫通孔３ａを形成するリング３ｂと、このリング３ｂの十字アーム上において起立した長尺、短尺二種の棒体３ｃ、３ｄから構成されている。４は、ベース１の底壁１ｃから内周壁１ｂにかけて設けられた副流路（底部貫通孔）である。この副流路４は注入筒２の切欠部２ａ（開封部材３から下側に位置する長さＬの範囲の開口面積）と協働して空気置換口を形成するものであり、詰替え容器の注出筒の内部通路の流路面積の１３２〜１７９％の開口面積Ｓにて開口されている。ここに、例えば、注出筒の内部通路の流路面積が１２８．6ｍｍ２の場合には、空気置換口の開口面積Ｓは、１７０〜２３０ｍｍ２の範囲に設定される（Ｓ＝１７０ｍｍ２の場合、Ｓ１＝７０ｍｍ２、Ｓ２＝１００ｍｍ２とするのが好ましく、Ｓ＝２３０ｍｍ２で、Ｓ１＝７０ｍｍ２、Ｓ２＝１６０ｍｍ２とするのが好ましい。） Reference numeral 3 denotes an opening member provided in the internal passage of the injection tube 2. The unsealing member 3 is fixedly held by a flange f formed in the internal passage of the injection tube 2, and a ring 3b that forms four fan-shaped through holes 3a by a cross arm and stands on the cross arm of the ring 3b. It consists of two types of long and short rods 3c and 3d. Reference numeral 4 denotes a secondary flow path (bottom through hole) provided from the bottom wall 1c of the base 1 to the inner peripheral wall 1b. This sub-flow channel 4 forms an air replacement port in cooperation with the cutout portion 2a of the injection tube 2 (opening area in the range of the length L located below the opening member 3). Is opened with an opening area S of 132 to 179% of the flow path area of the internal passage of the dispensing cylinder. Here, for example, when the flow passage area of the internal passage of the pouring cylinder is 128.6Mm 2, the opening area S of the air displacement ports is set to a range of 170～230Mm 2 of (S = 170 mm 2 In this case, S 1 = 70 mm 2 and S 2 = 100 mm 2 are preferable, and S = 230 mm 2 and S 1 = 70 mm 2 and S 2 = 160 mm 2 are preferable.)

ベース１の底壁１ｃは、一方から他方に向けて傾斜した傾斜壁からなっており、内容物の詰替えに際して注入筒２の切欠部２ａから内容物が漏れ出ても漏れ出た内容物は空気置換口を形成する副流路４を通して全て継続使用容器内へ流れ込むように該副流路４は底壁１ｃがもっとも低くなる部位に形成されている。   The bottom wall 1c of the base 1 is composed of an inclined wall inclined from one side to the other. Even when the content leaks out from the cutout portion 2a of the injection tube 2 when the content is refilled, the leaked content is The sub-flow channel 4 is formed in a portion where the bottom wall 1c is lowest so that all flow into the continuous use container through the sub-flow channel 4 forming the air replacement port.

さらに、５は、外周壁１ａと内周壁１ｂとをつなぐ天壁１ｄにおいて設けられた環状体である。この環状体５の外周面にはねじ部が設けられおり、この環状体５には図示しないオーバーキャップのねじ部を係合させることによって継続使用容器を密封状態に保持する（アンダーカットによる係合であってもよい。）。   Further, 5 is an annular body provided on the top wall 1d that connects the outer peripheral wall 1a and the inner peripheral wall 1b. The annular body 5 is provided with a threaded portion, and the annular body 5 is held in a sealed state by engaging a threaded portion of an overcap (not shown) (engaged by undercut). May be.)

図２、３は、詰替え容器と、継続使用容器との関係を詰替え前、詰替え中の状態として示した図である。図において６は、二軸延伸ブロー成形によって成形された薄肉の詰替え容器（パウチ等の容器を適用してもよい。）、７は、注入筒２の内側に入り込む径を有し詰替え容器６の口部６ａにねじ止めされた例で示した注出筒である。注出筒７には、内部通路７ａ内に着脱可能な密封蓋７ｂが設けられており、図２に示すように倒立姿勢にした容器の注出筒７を注入筒２に入れ込み、図３の如く開封部材３によって密封蓋７ｂを押し込むことで内部通路７ａが開通する。このとき、密封蓋７bが内部通路７ａを塞ぎ内容物の流出を阻害することがないように、短尺の棒体３ｄと注出筒７の内壁面との間に密封蓋７ｂを入り込ませて該密封蓋７ｂの倒れ込みを防止するのがよい。   2 and 3 are views showing the relationship between the refill container and the container for continuous use as being in a state before refilling and during refilling. In the figure, 6 is a thin-walled refill container formed by biaxial stretch blow molding (a container such as a pouch may be applied), and 7 is a refill container having a diameter that enters the inside of the injection tube 2. 6 is a dispensing cylinder shown in the example screwed to the mouth portion 6a. The dispensing cylinder 7 is provided with a detachable sealing lid 7b in the internal passage 7a, and the dispensing cylinder 7 in an inverted position as shown in FIG. Thus, the internal passage 7a is opened by pushing the sealing lid 7b by the opening member 3. At this time, the sealing lid 7b is inserted between the short rod 3d and the inner wall surface of the dispensing cylinder 7 so that the sealing lid 7b does not block the internal passage 7a and prevent the outflow of the contents. It is preferable to prevent the sealing lid 7b from falling down.

図４に詰替え容器６の注出筒７と、継続使用容器に設けられた受液栓の注入筒２の断面を示すように、内容物が容器の反転によって自然に流れ出る置換タイプの容器にあっては、注出筒７と注入筒２の通路の面積比が、およそ１：１となっておりとくに問題はないものの、強制排出タイプの容器では、およそ１．６：１、その境界に位置するタイプの容器にあっては、およそ１.２：１であって、境界タイプ、強制排出タイプのものでは、注入筒２の流路面積と注出筒７の流路面積の比が０.８６以下であり、容器を反転しても容器から息つぎ状（空気置換）に内容物が自然排出することがないため、容器の胴部に力を加えて強制的に押し潰さなければならないが、この場合、内容物が大量に流れ出てしまうこともあり、空気置換口内でのバブリング現象は避けられない。   As shown in FIG. 4 which shows a cross section of the dispensing cylinder 7 of the refill container 6 and the injection cylinder 2 of the liquid receiving stopper provided in the continuous use container, the contents of the replacement type container which naturally flows out by reversing the container. In this case, although the area ratio of the passage of the injection tube 7 and the injection tube 2 is about 1: 1 and there is no particular problem, in the forced discharge type container, about 1.6: 1, at the boundary. In the case of the located type container, the ratio is approximately 1.2: 1, and in the case of the boundary type and the forced discharge type, the ratio of the flow area of the injection cylinder 2 to the flow area of the extraction cylinder 7 is 0. It is less than .86, and even if the container is inverted, the contents do not spontaneously expel from the container in the form of a breath (air replacement), so it must be forced to crush by applying force to the body of the container However, in this case, a large amount of contents may flow out, and the bubble in the air replacement port Packaging phenomenon is inevitable.

本発明は、注入筒２の流路面積と注出筒の内部通路の流路面積との比が０.８６以下となるものにおいて、注出筒７の内部通路の流路面積の１３２〜１７９％の面積にて開口された空気置換口を形成したため、詰替え容器６の胴部を押し潰して内容物を強制的に排出するような詰替えを行っても空気置換口４から内容物が溢れだすことがなくスムーズな詰替えが行える。   In the present invention, the ratio of the flow passage area of the injection tube 2 to the flow passage area of the internal passage of the extraction tube is 0.86 or less. Since the air replacement port opened in an area of% is formed, the content is removed from the air replacement port 4 even if refilling is performed such that the body of the refill container 6 is crushed and the content is forcibly discharged. Smooth refill without overflowing.

具体的には、注出筒７の流路面積が１２８.６ｍｍ２である場合、空気置換口４の開口面積は１７０ｍｍ２〜２３０ｍｍ２の範囲に設定するのが望ましい。 Specifically, when the flow passage area of the pouring cylinder 7 is 128.6Mm 2, the opening area of the air displacement ports 4 can be set from the range of 170mm 2 ~230mm 2.

注出筒７の流路面積が１２８.６ｍｍ２の場合において空気置換口４の開口面積が１７０ｍｍ２未満になると、詰替え容器６の胴部を加圧して内容物を排出する強制排出タイプのものにあっては、空気置換口内でバルリング現象が起こって内容物が溢れ出るのが避けられず、一方、２３０ｍｍ２を超える場合には、継続使用容器の使用において継続使用容器を傾ける際に該空気置換口から内容物が流れ出る不具合がある。 If the flow passage area of the pouring cylinder 7 the opening area of the air displacement ports 4 is less than 170 mm 2 in the case of 128.6mm 2, forced exhaust type for discharging the contents pressurizes the body of the refill container 6 In the case of a product, it is inevitable that the contents will overflow due to the occurrence of a balling phenomenon in the air replacement port. On the other hand, if the content exceeds 230 mm 2 , There is a problem that contents flow out of the air replacement port.

空気置換口は矩形状のものを例として示したが、その形状はとくに限定されるものではなく、ベースの形状に応じて種々変更することができる。   The air replacement port is shown as a rectangular shape as an example, but the shape is not particularly limited and can be variously changed according to the shape of the base.

実施例
上掲図２、３に示すような詰替え容器（注出筒の通路の流路面積１２８.６ｍｍ２）内の内容物を継続使用容器（注入筒の流路面積８１.８ｍｍ２）に移し替えるべく受液栓の空気置換口の開口面積Ｓを種々変更（１６０ｍｍ２、１７０ｍ２、２００ｍｍ２、２３０ｍｍ２、２５０ｍｍ２）して詰替えを行い（注入筒の流路面積と注出筒の流路面積との比０.６４）、その際の状況を観察した。 Example The contents in the refilling container (the flow path area of the passage of the extraction cylinder 128.6 mm 2 ) as shown in FIGS. 2 and 3 are used continuously (the flow area of the injection cylinder 81.8 mm 2 ). The opening area S of the air replacement port of the liquid receiving stopper is changed variously (160 mm 2 , 170 m 2 , 200 mm 2 , 230 mm 2 , 250 mm 2 ) and refilled (the flow area of the injection cylinder and the extraction) The ratio to the flow path area of the cylinder was 0.64), and the situation at that time was observed.

その結果、空気置換口の開口面積Ｓの、注出筒の通路の開口面積に対する割合が１３２〜１７９％の範囲に収まる場合にあっては、内容物がスムーズに移し替えられことが確認された。これに対して空気置換口の開口面積Ｓの、注出筒の通路の開口面積の１３２％を下回るものにあっては、空気置換口内でバブリング現象が発生し液が溢れ出るのが避けられず、空気置換口の開口面積Ｓの、注出筒の通路の開口面積に対する割合が１７９％を超えるものにあっては、バブリング現象が発生することがなかったものの継続使用容器から内容物を注出する際に空気置換口から内容物が流れ出るのが避けられなかった。   As a result, it was confirmed that the contents were smoothly transferred when the ratio of the opening area S of the air replacement port to the opening area of the passage of the dispensing cylinder was in the range of 132 to 179%. . On the other hand, when the opening area S of the air replacement opening is less than 132% of the opening area of the passage of the dispensing cylinder, it is inevitable that a bubbling phenomenon occurs in the air replacement opening and the liquid overflows. In the case where the ratio of the opening area S of the air replacement port to the opening area of the passage of the dispensing cylinder exceeds 179%, the bubbling phenomenon did not occur, but the contents were poured out from the continuous use container. It was inevitable that the contents would flow out of the air replacement port.

詰替え容器の胴部を強制的に押し潰す詰替えを行っても詰替え中において内容物が空気置換口から溢れ出たり、あるいは継続使用容器の使用中において内容物が空気置換口から流れ出ることのない受液栓が提供できる。   Even if refilling is performed by forcibly crushing the body of the refill container, the contents overflow from the air replacement port during refilling, or the content flows out of the air replacement port during continuous use of the container. It is possible to provide a liquid receiving stopper without any other.
