容器本体の底壁を押し込むことにより、ノズルの貫通路を通して内容物を外界に注出するものとしては、例えば、滴下式注出容器と呼ばれるものがある（例えば、「特許文献１」参照）。 As what discharges the contents to the outside through the through-passage of the nozzle by pushing the bottom wall of the container main body, there is, for example, a so-called drop-type dispensing container (see, for example, “Patent Document 1”).
しかしながら、こうした容器は、ノズルの先端を下に向ける等すると、ノズルから内容物が垂れ易いという問題があった。また、こうした容器は、底壁の押し込みにより内容物を取り出す構造のため、容器本体内の圧力が上昇すると、内容物が飛び出す（噴出する）ことがある。 However, such a container has a problem that the contents easily sag from the nozzle when the tip of the nozzle is directed downward. Moreover, since such a container is a structure which takes out the content by pushing in a bottom wall, when the pressure in a container main body rises, the content may jump out (spout).
本発明の目的とするところは、底壁を押し込むことで充填空間を加圧して内容物を外界に圧送する一方、押し込みの解除によって外気を導入することで、再び底壁の押し込みにより、内容物を圧送が可能となるノズル付き押出容器にあって、予期せぬ内容物の噴出や垂れを防止することにある。 The object of the present invention is to pressurize the filling space by pushing the bottom wall and pump the contents to the outside, while introducing the outside air by releasing the pushing, and again by pushing the bottom wall, the contents It is in the extrusion container with a nozzle which can carry out pressure feeding, and it is in preventing the unexpected ejection and dripping of the contents.
胴体部分を形成する周壁と当該周壁の下端に繋がる底壁とを有して周壁と底壁によって形成された充填空間に内容物が充填される容器本体と、周壁の開口端に固定保持される装着筒および該容器本体の軸線に沿って延びる貫通路を有し、底壁の押し込みによって圧送された内容物が貫通路を通して外界に排出される一方、押し込みの解除によって外気が貫通路を通して吸入されるノズルとを備えたノズル付き押出容器であって、
周壁の開口端の内側に、ノズルの貫通路に向かって突出して充填空間から圧送された内容物を貫通路側に通じさせる開口部を有して先端部頂面がノズルの貫通路に直交する平面状の弁座としてなる仕切壁を設けると共に、当該仕切壁に弾性弁を設け、
当該弾性弁は、仕切壁に差し込まれる下端開口部が形成されるとともに該下端開口部の側から仕切壁の先端部頂面の側に向かって延在する延在部と該延在部に連なるとともに該延在部から離れるに連れて縮径する縮径部と該縮径部から内向きに折り返された折り返し部と該折り返し部に前記先端部頂面に向かって突出して設けられた環状の先端側端縁とを備えた筒状の基部を有し、当該筒状の基部の先端側端縁が当該弁座に全周に亘って着座して充填空間と貫通路との間を仕切ると共に、内容物の圧送により貫通路側に弾性変形することで弁座から離間して充填空間を貫通路に通じさせる吐出弁としてなる一方、
当該筒状の基部の外周側から突出した外周側端縁がノズルの装着筒に設けた弁座に全周に亘って着座して当該筒状の基部と装着筒との間に形成された環状の隙間と貫通路との間を仕切ると共に、環状の隙間に生じた負圧により充填空間側に弾性変形することでノズルの装着筒に設けた弁座から離間して環状の隙間を貫通路に通じさせる外気吸入弁としてなり、
仕切壁に、環状の隙間を充填空間に通じさせる貫通孔を形成することを特徴とするものである。
A container body having a peripheral wall forming the body portion and a bottom wall connected to the lower end of the peripheral wall and filled with contents in a filling space formed by the peripheral wall and the bottom wall, and fixedly held at the open end of the peripheral wall There is a through passage extending along the axis of the mounting cylinder and the container body, and the contents pumped by pushing the bottom wall are discharged to the outside through the through passage, while outside air is sucked through the through passage by releasing the push. An extrusion container with a nozzle comprising:
A plane that has an opening inside the opening end of the peripheral wall that protrudes toward the through passage of the nozzle and allows the contents pumped from the filling space to communicate with the through passage, and the top surface of the tip is perpendicular to the through passage of the nozzle A partition wall serving as a valve seat, and an elastic valve on the partition wall,
It said resilient valve connected to the extending portion and the extending portion extending toward the side of the tip top face of the partition wall from the side of the lower end opening with a lower end opening portion to be inserted into the partition wall is formed In addition, a diameter-reduced portion that is reduced in diameter as it is separated from the extending portion , a folded portion that is folded inwardly from the reduced-diameter portion, and an annular shape that is provided on the folded portion so as to protrude toward the top surface of the distal end portion. A cylindrical base portion having a distal end edge, and the distal end edge of the cylindrical base portion is seated on the valve seat over the entire circumference to partition between the filling space and the through passage. On the other hand, it becomes a discharge valve that is elastically deformed to the through passage side by pumping of the contents and is separated from the valve seat and leads the filling space to the through passage
An outer peripheral edge projecting from the outer peripheral side of the cylindrical base is seated over the entire circumference on a valve seat provided on the nozzle mounting cylinder, and is formed between the cylindrical base and the mounting cylinder In addition to partitioning between the gap and the through-passage, and elastically deforming toward the filling space by the negative pressure generated in the annular gap, the annular gap is separated from the valve seat provided in the nozzle mounting cylinder. As an outside air intake valve to communicate,
The partition wall is formed with a through hole that allows the annular gap to communicate with the filling space.
本発明によれば、容器を倒立させても、内容物を積極的に加圧しない限り、吐出弁によりノズルの貫通路が遮断されているため、内容物の噴出や垂れを生じることがない。このため、本発明によれば、予期せぬ内容物の噴出や垂れを生じないノズル付き押出容器を提供することができる。 According to the present invention, even if the container is inverted, unless the contents are positively pressurized, the nozzle passage is blocked by the discharge valve, so that the contents are not ejected or drooped. For this reason, according to this invention, the extrusion container with a nozzle which does not produce the ejection and dripping of the unexpected content can be provided.
また、本発明は、吐出弁と外気吸入弁とが一体に構成されているため、部品点数の削減を図りつつ、簡易な構造を実現することができる。 In the present invention, since the discharge valve and the outside air intake valve are integrally formed, a simple structure can be realized while reducing the number of parts.
更に、本発明は、上述のとおり、充填空間の内容物を貫通路まで圧送する経路と、貫通路から導入した外気を充填空間に導入するまでの経路とを分けたため、吐出弁の先端に空気が巻き込まれることがないから、安定した吐出が可能となる。 Furthermore, as described above, the present invention separates the path for pumping the contents of the filling space to the through-passage and the path for introducing the outside air introduced from the through-passage into the filling space. Therefore, stable discharge is possible.
以下、図面を参照して、本発明に従う、ノズル付き押出容器の各形態を詳細に説明する。 Hereinafter, with reference to drawings, each form of the extrusion container with a nozzle according to this invention is demonstrated in detail.
図中、符号１は、容器本体である。容器本体１は、胴体部分を形成する周壁２と、この周壁２の下端に繋がる底壁３とを有する。これにより、容器本体１は、周壁２と底壁３によって内容物が充填される充填空間Ｓ0を形成する。底壁３は、外部からの押し込みにより変形し、その押し込みを解除することにより復元する弾性材料からなる。また、底壁３は、周壁２に対してリング部材４によって抜け止め保持されている。 In the figure, reference numeral 1 denotes a container body. The container body 1 includes a peripheral wall 2 that forms a body portion, and a bottom wall 3 that is connected to the lower end of the peripheral wall 2. Thereby, the container body 1 forms a filling space S 0 filled with the contents by the peripheral wall 2 and the bottom wall 3. The bottom wall 3 is made of an elastic material that is deformed by pushing from the outside and restored by releasing the pushing. Further, the bottom wall 3 is held against the peripheral wall 2 by a ring member 4.
符号５は、貫通路Ｒを有するノズルである。ノズル５は、その下端を拡径させてなる肩部６から装着筒７が一体に垂下する。装着筒７は、肩部６に繋がる外筒７ａに、フランジ７ｂを介して嵌合筒７ｃが一体に繋がる。ノズル５は、嵌合筒７ｃを介して周壁２の開口端に、スプライン嵌合Ｃ1及びアンダーカット嵌合Ｃ2によって固定保持される。 Reference numeral 5 denotes a nozzle having a through passage R. As for the nozzle 5, the mounting cylinder 7 hangs down integrally from the shoulder part 6 which expanded the diameter of the lower end. In the mounting cylinder 7, the fitting cylinder 7 c is integrally connected to the outer cylinder 7 a connected to the shoulder portion 6 via the flange 7 b. The nozzle 5 is fixedly held by the spline fitting C 1 and the undercut fitting C 2 at the opening end of the peripheral wall 2 through the fitting cylinder 7c.
これにより、ノズル５は、底壁３が押し込まれることによって充填空間Ｓ0から圧送された内容物を、貫通路Ｒを通して外界に排出する一方、底壁３の押し込みが解除されることによって貫通路Ｒを通して外気を導入する。 As a result, the nozzle 5 discharges the content pumped from the filling space S 0 when the bottom wall 3 is pushed into the outside through the through-passage R, while the pushing-through of the bottom wall 3 is released to release the through-passage. Introducing outside air through R.
周壁２の開口端の内側には、ノズルの貫通路Ｒに向かって突出する、先細り状の仕切壁が一体に設けられている。仕切壁は、図２に示すように、周壁２の内周面と環状の内向きフランジ８を介して繋がる大径筒部９と、この大径筒部９と環状の段差部１０を介して繋がる小径筒部１１とを有する。仕切壁の先端部１２は、後述のように弁座として機能し、小径筒部１１の周方向に間隔を空けて配置された複数のアーム１３で保持されている。これにより、仕切壁には、アーム１３の間に、小径筒部１１の上端開口を通して充填空間Ｓ0に通じる複数の開口部Ａ1が形成されている。 On the inner side of the opening end of the peripheral wall 2, a tapered partition wall that protrudes toward the through passage R of the nozzle is integrally provided. As shown in FIG. 2, the partition wall includes a large-diameter cylindrical portion 9 connected to the inner peripheral surface of the peripheral wall 2 via an annular inward flange 8, and a large-diameter cylindrical portion 9 and an annular stepped portion 10. And a small-diameter cylindrical portion 11 to be connected. The distal end portion 12 of the partition wall functions as a valve seat as will be described later, and is held by a plurality of arms 13 arranged at intervals in the circumferential direction of the small diameter cylindrical portion 11. As a result, a plurality of openings A 1 are formed in the partition wall between the arms 13 and communicate with the filling space S 0 through the upper end opening of the small-diameter cylindrical portion 11.
符号２０は、変形及び復元の可能な、例えば、ゴムやエラストマ等の弾性材料からなる弾性弁である。弾性弁２０は、図２に示すように、筒状の基部（以下、「筒状基部」）２１を有する。この筒状基部１１には、仕切壁の小径筒部１１に差し込まれる下端開口部が形成されている。これにより、弾性弁２０は、仕切壁の小径筒部１１に嵌合保持されている。 Reference numeral 20 denotes an elastic valve made of an elastic material such as rubber or elastomer, which can be deformed and restored. As shown in FIG. 2, the elastic valve 20 has a cylindrical base (hereinafter, “cylindrical base”) 21. The cylindrical base portion 11 is formed with a lower end opening portion that is inserted into the small diameter cylindrical portion 11 of the partition wall. Thereby, the elastic valve 20 is fitted and held in the small diameter cylindrical portion 11 of the partition wall.
また、筒状基部２１の先端側部分２３は、仕切壁の先端部（以下、「弁座」）１２の頂面ｆ1に向かって延在する延在部２３ａと、頂面ｆ1に向かって縮径する縮径部２３ｂと、この縮径部２３ｂから頂面ｆ1の上側から内向きに折り返す折り返し部２３ｃとを有し、折り返し部２３ｃの内側には開口部Ａ2が形成されている。 Further, the distal end portion 23 of the cylindrical base portion 21 extends toward the top surface f 1 of the partition wall distal end portion (hereinafter referred to as “valve seat”) 12 and the top surface f 1 . A diameter-reducing portion 23b that is reduced in diameter, and a folded portion 23c that is folded inward from the top surface f 1 from the reduced-diameter portion 23b. An opening A 2 is formed inside the folded portion 23c. Yes.
また折り返し部２３ｃには、開口部Ａ2に沿って頂面ｆ1に向かって突出する環状の先端側端縁２３ｄが設けられている。先端側端縁２３ｄは、弁座１２の頂面（以下、「座面」）ｆ1に全周に亘って着座して仕切壁の開口部Ａ1を閉じることで、充填空間Ｓ0と、ノズルの貫通路Ｒとの間を仕切っている。これにより、先端側部分２３は、充填空間Ｓ0からの内容物が開口部Ａ1を通して圧送されない限り、実線に示すように、弁座１２に着座して内容物の流出を阻止するが、充填空間Ｓ0から内容物が圧送されると、破線に示すように、下流側（図面上向きの側）に弾性変形することで、弁座１２から離間して、弾性弁２０の開口部Ａ2と仕切壁の開口部Ａ2とを介して充填空間Ｓ0を貫通路Ｒに通じさせる。即ち、先端側部分２３は、吐出弁として機能する。 Further the folded portion 23c, an annular tip end edge 23d projecting toward the top face f 1 is provided along the opening A 2. Distal side edge 23d is a top surface of the valve seat 12 (hereinafter, "seating surface") seated over the entire circumference to f 1 by closing the opening A 1 of the partition wall, a filling space S 0, The nozzle is partitioned from the through passage R. As a result, the tip end portion 23 is seated on the valve seat 12 to prevent the contents from flowing out as shown by the solid line unless the contents from the filling space S 0 are pumped through the opening A 1. When the content is pumped from the space S 0 , as shown by the broken line, it is elastically deformed to the downstream side (upward side in the drawing), thereby being separated from the valve seat 12 and the opening A 2 of the elastic valve 20. The filling space S 0 is communicated with the through passage R through the opening A 2 of the partition wall. That is, the tip end portion 23 functions as a discharge valve.
なお、本発明に従えば、吐出弁として機能は、折り返し部分２３ｃ及び先端側端縁２３ｄだけでも可能であるが、本形態の如く、先端側部分に縮径部２３ｂを設ければ、吐出弁としての開閉動作が良好なものとなる。 According to the present invention, the discharge valve can function only by the folded portion 23c and the distal end edge 23d. However, if the reduced diameter portion 23b is provided at the distal end portion as in this embodiment, the discharge valve As a result, the opening and closing operation is good.
他方、筒状基部２１の外周側から突出した外周側部分２４は、装着筒７に向かって拡径し、その外周側端縁１４ａがフランジ（弁座）７ｂの裏面（以下、「座面」）ｆ2に全周に亘って着座して筒状基部２１と装着筒７との間に形成された環状の隙間（以下、「環状隙間」）Ｓ2と貫通路Ｒとを仕切っている。これにより、外周側部分２４は、充填空間Ｓ0に負圧が生じない限り、実線で示すように、フランジ７ｂに着座して外気の流入を阻止するが、充填空間Ｓ0に負圧が生じると、破線に示すように、上流側（図面下向きの側）に弾性変形することで、フランジ７ｂから離間して、貫通路Ｒを環状隙間Ｓ2に通じさせる。 On the other hand, the outer peripheral side portion 24 protruding from the outer peripheral side of the cylindrical base portion 21 increases in diameter toward the mounting cylinder 7, and the outer peripheral side edge 14 a is the back surface of the flange (valve seat) 7 b (hereinafter “seat surface”). ) It sits on the entire circumference of f 2 and partitions the annular gap (hereinafter referred to as “annular gap”) S 2 formed between the cylindrical base 21 and the mounting cylinder 7 and the through passage R. As a result, as long as no negative pressure is generated in the filling space S 0 , the outer peripheral side portion 24 is seated on the flange 7b to prevent inflow of outside air as shown by a solid line, but negative pressure is generated in the filling space S 0. When, as shown in broken lines, by elastic deformation on the upstream side (drawing down side), spaced from the flange 7b, it causes through the through-passage R in the annular clearance S 2.
そして、仕切壁の大径筒部９には、環状隙間Ｓ2を充填空間Ｒに通じさせる貫通孔Ａ3が形成されている。即ち、外周側部分２４は、外気吸入弁として機能する。なお、貫通孔Ａ3については、先端部１２と同様、大径筒部９を複数のアームで構成し、当該アームの相互間に形成された開口部をもって貫通孔Ａ3とすることができる。 Then, the large-diameter cylindrical portion 9 of the partition wall, a through hole A 3 giving through an annular gap S 2 to the filling space R is formed. That is, the outer peripheral side portion 24 functions as an outside air intake valve. Note that the through-hole A 3, similar to the tip 12, the large-diameter cylindrical portion 9 composed of a plurality of arms, with a opening formed therebetween of the arms may be the through hole A 3.
本形態によれば、容器本体１の底壁３を押し込むと、内容物を充填した充填空間Ｓ0の圧力が増大することにより、先端側部分（以下、「吐出弁」）２３が開放される。即ち、内容物は、底壁３を押し込むと、吐出弁２３からノズル５の貫通路Ｒを通して外界に圧送される。他方、外気吸入弁２４は、充填空間Ｓ0に負圧が生じていないため、開放されることがない。このため、外気は、底壁３の押し込みによっては貫通路Ｒを通して充填空間Ｓ0に導入されることがない。 According to this embodiment, when the bottom wall 3 of the container body 1 is pushed in, the pressure in the filling space S 0 filled with the contents increases, so that the tip side portion (hereinafter referred to as “discharge valve”) 23 is opened. . That is, when the bottom wall 3 is pushed in, the contents are pumped from the discharge valve 23 to the outside through the through passage R of the nozzle 5. On the other hand, the outside air intake valve 24, since the negative pressure in the filling space S 0 does not occur, it will not be opened. For this reason, the outside air is not introduced into the filling space S 0 through the through passage R due to the pushing of the bottom wall 3.
これに対し、底壁３の押し込みを解除すると、底壁３の復帰により充填空間Ｓ0に負圧が生じることにより、外気吸入弁２４が開放される。即ち、外気は、底壁３の押し込みが解除されると、貫通路Ｒから外気吸入弁２４を通して充填空間Ｓ0に吸入される。他方、吐出弁２３は、充填空間Ｓ0が加圧されていないため、初期位置（図２の実線）に復元し、開放されることがない。このため、内容物は、底壁３の押し込みの解除によっては貫通路Ｒを通して外界に圧送されることがない。 On the other hand, when the pushing of the bottom wall 3 is released, a negative pressure is generated in the filling space S 0 by the return of the bottom wall 3, thereby opening the outside air intake valve 24. That is, outside air is sucked into the filling space S 0 from the through passage R through the outside air suction valve 24 when the pushing of the bottom wall 3 is released. On the other hand, the discharge valve 23, the filling space S 0 is not pressurized, the initial position is restored (the solid line in FIG. 2), it will not be opened. For this reason, the content is not pumped to the outside through the through passage R by releasing the pushing of the bottom wall 3.
従って、本形態によれば、容器を倒立させても、内容物を積極的に加圧しない限り、吐出弁２３によりノズル５の貫通路Ｒが遮断されているため、内容物の噴出や垂れを生じることがない。このため、本形態によれば、予期せぬ内容物の噴出や垂れを生じないノズル付き押出容器を提供することができる。 Therefore, according to this embodiment, even if the container is inverted, unless the contents are positively pressurized, the discharge valve 23 blocks the through passage R of the nozzle 5, so that the contents can be ejected or drooped. It does not occur. For this reason, according to this form, the extrusion container with a nozzle which does not produce the ejection and dripping of the unexpected content can be provided.
また、本形態は、吐出弁２３と外気吸入弁２４とが一体に構成されているため、部品点数の削減を図りつつ、簡易な構造を実現することができる。 Further, in this embodiment, since the discharge valve 23 and the outside air intake valve 24 are integrally configured, a simple structure can be realized while reducing the number of parts.
更に、本形態は、上述のとおり、充填空間Ｓ0の内容物を貫通路Ｒまで圧送する経路と、貫通路Ｒから導入した外気を充填空間Ｓ0に導入するまでの経路とを分けたため、吐出弁２３の先端側端縁２３ｄに空気が巻き込まれることがないから、安定した吐出が可能となる。 Furthermore, as described above, the present embodiment separates the route for pumping the contents of the filling space S 0 to the through-passage R and the route for introducing the outside air introduced from the through-passage R into the filling space S 0 . Since air is not caught in the front end side edge 23d of the discharge valve 23, stable discharge becomes possible.
図３は、参考例のノズル付き押出容器の要部拡大側面図である。参考例の形態では、弾性弁は、同形態の弾性弁２０のように、筒状基部２１の先端側端縁２３ｄは、仕切壁の先端部側面ｆ3に着座する。なお、本参考例において、図１及び２と同一の部分は同一の符号をもって、その説明を省略する。 FIG. 3 is an enlarged side view of an essential part of an extrusion container with a nozzle according to a reference example . In the form of the reference example, the elastic valve, as in the elastic valve 20 of the embodiment, the tip end edge 23d of the tubular base portion 21 is seated on the tip portion side surface f3 of the partition walls. In this reference example , the same portions as those in FIGS. 1 and 2 are denoted by the same reference numerals, and the description thereof is omitted.
上述したところは、本発明の一形態を示したにすぎず、本発明に従えば、種々の変更を加えることができる。例えば、本形態では、ノズル５には、バージンキャップ４０が設けられている。バージンキャップ４０は、肩部６に固定される本体３１と、この本体４１に対して破断によって分離可能なオーバーキャップ４２とで構成されているが、キャップはこれに限定されるものではなく、様々なタイプのキャップを採用することができる。また、ノズル５を容器本体に装着する手段も、スプライン嵌合Ｃ1とアンダーカット嵌合Ｃ2との組み合わせによるものだけでなく、凹凸や凸同士の嵌合等の様々な手段を採用できる。 The above description shows only one embodiment of the present invention, and various modifications can be made according to the present invention. For example, in this embodiment, the nozzle 5 is provided with a virgin cap 40. The virgin cap 40 includes a main body 31 fixed to the shoulder portion 6 and an overcap 42 that can be separated from the main body 41 by breaking. However, the cap is not limited thereto, and various Various types of caps can be used. The means for attaching the nozzle 5 to the container body is not limited to a combination of the spline fitting C 1 and the undercut fitting C 2, and various means such as concavity and convexity fitting can be adopted.
本発明は、底壁の押し込みによって圧送された内容物が貫通路を通して外界に排出される一方、押し込みの解除によって外気が貫通路を通して吸入されるノズル付き押出容器であれば、化粧用容器、医療用容器等の、様々な容器に適用することができる。 The present invention is a cosmetic container, a medical container, as long as it is an extruded container with a nozzle, while the contents pumped by pushing the bottom wall are discharged to the outside through the through passage, and the outside air is sucked through the through passage by releasing the push. It can be applied to various containers such as a container for use.
