Description

本発明は、容器口部に嵌合され、容器内部に収容された内容物を吐出する吐出キャップに関する。   The present invention relates to a discharge cap that is fitted into a container opening and discharges contents contained in a container.

従来、容器内部に収容された液状内容物または粘性を有する流動性内容物を吐出する吐出キャップとして、容器内部と吐出口との間に逆止弁が設けられている吐出キャップが公知である。この吐出キャップは、容器から内容物を吐出する際に、容器の外部から加圧された内容物が逆止弁を弁座から離脱させることで、容器内部から吐出口へ内容物が通過し吐出するとともに、内容物への加圧を解除することで、逆止弁が弁座に密着し容器を密閉するため、容器内部を外気から遮断でき、容器内部に残っている内容物の乾燥や酸化等の劣化を防ぐことができる。   2. Description of the Related Art Conventionally, a discharge cap in which a check valve is provided between the inside of a container and a discharge port is known as a discharge cap that discharges a liquid content contained in the container or a fluid content having viscosity. When discharging the contents from the container, the discharge cap causes the contents pressurized from the outside of the container to release the check valve from the valve seat so that the contents pass from the inside of the container to the discharge port and are discharged. At the same time, by releasing the pressure on the contents, the check valve adheres to the valve seat and seals the container, so that the inside of the container can be shut off from the outside air, and the contents remaining inside the container can be dried or oxidized. Etc. can be prevented.

例えば、特許文献1等で公知の吐出キャップは、容器口部と嵌合する嵌合部と、容器内部に収容された内容物を吐出する吐出口とを有するとともに、容器内部と吐出口との間に区画された弁室をさらに有し、弁室には、容器内部と連通し、内容物を取り出す供給孔及び弁座を有する底部と、逆止弁とが設けられ、逆止弁は供給孔の軸線方向に沿って摺動可能に設けられるとともに、弁座方向に付勢されて弁座と当接可能に構成されており、可撓性の容器に取り付けて使用する場合は容器を握る等して圧力をかけることで逆止弁が弁座から離脱し、内容物を吐出口から吐出するものであり、使用時以外は逆止弁によって供給孔は閉塞されているため、容器内部に残っている内容物の乾燥や参加等の劣化を防ぐことができる。   For example, a well-known discharge cap in Patent Document 1 or the like has a fitting portion that fits into the container mouth portion, and a discharge port that discharges the contents contained in the container, and the inside of the container and the discharge port. The valve chamber further includes a valve chamber which is partitioned between the bottom of the valve chamber, which communicates with the interior of the container and has a supply hole and a valve seat for taking out the contents, and a check valve. It is provided so as to be slidable along the axial direction of the hole, and is configured to be urged in the valve seat direction so as to come into contact with the valve seat, and grips the container when attached to a flexible container. The check valve is released from the valve seat by applying pressure, etc., and the contents are discharged from the discharge port.The supply hole is closed by the check valve except during use. Deterioration such as drying and participation of the remaining contents can be prevented.

しかしながら、特許文献1等で公知の吐出キャップには、未だ改善の余地があった。
すなわち、逆止弁によって容器内部を外気から遮断することはできるが、使用時に逆止弁による閉塞を解除する際、必要以上の圧力で容器を押圧してしまうと、逆止弁が弁座から急に大きく移動して流路が開きすぎてしまい、必要以上に多くの内容物を吐出してしまう虞があった。
また、弁座からの離脱圧力が高くなるような逆止弁を使用することで、流路が大きく開きにくい構成にすることも考えられるが、逆止弁が弁座から離脱するまでに時間がかかるとともに、逆止弁が弁座から離脱する際に必要な押圧力が大きいため、急激に内容物が吐出されることで内容物の流れに乱れが発生し、吐出時に周囲に飛び散る虞があった。
However, there is still room for improvement in the discharge cap known in Patent Document 1 and the like.
That is, the inside of the container can be shut off from the outside air by the check valve, but when releasing the blockage by the check valve at the time of use, if the container is pressed with an excessive pressure, the check valve is removed from the valve seat. There was a risk that the flow would suddenly move and the flow path would open too much, discharging more content than necessary.
In addition, by using a check valve that increases the release pressure from the valve seat, it may be possible to make the flow path large and difficult to open, but it takes time to release the check valve from the valve seat. At the same time, the pressing force required when the check valve separates from the valve seat is large, so that the content is suddenly discharged and the flow of the content is disturbed, and there is a risk of scattering around the discharge. It was.

本発明は、これらの問題点を解決するものであり、簡単な構成で、逆止弁の弁座からの離脱圧力が変わらず、必要以上に容器を押圧した場合でも必要以上のストローク量で逆止弁が弁座から離脱することがなく、吐出時に内容物が飛び散るような勢いを抑制可能な吐出キャップを提供することを目的とするものである。   The present invention solves these problems, and with a simple configuration, the release pressure from the valve seat of the check valve does not change, and even when the container is pressed more than necessary, the reverse is performed with an excessive stroke amount. It is an object of the present invention to provide a discharge cap capable of suppressing the momentum that the contents are scattered at the time of discharge without the stop valve being detached from the valve seat.

本発明の吐出キャップは、容器口部に嵌合され、容器内部に収容された内容物を傾斜させて吐出する吐出キャップであって、該吐出キャップは、本体天面と前記本体天面から垂下し前記容器口部と嵌合する嵌合部と、前記本体天面から上方に延出し、容器内部に収容された内容物を吐出する吐出筒と、前記容器内部と前記本体天面との間に区画された弁室とを有し、前記吐出筒の先端には吐出時に傾斜した際に下方に位置する吐出誘導部が設けられており、前記弁室には、容器内部と連通し内容物を取り出す供給筒及び弁座を有する底部と、逆止弁とが設けられ、前記逆止弁は前記供給筒の軸線方向に沿って移動可能に設けられるとともに、前記弁座方向に付勢されて前記弁座と当接可能に構成され、前記逆止弁の上面と前記本体天面の下面との間には、前記逆止弁の可動範囲を規制する少なくとも2つの規制部材が設けられ、前記規制部材は、上方から見て吐出時に傾斜する方向の反対から、前記吐出筒の中心軸を中心として時計回り及び反時計回り方向にそれぞれ135度ずつの角度範囲にのみ形成されていることにより、前記課題を解決するものである。   The discharge cap of the present invention is a discharge cap that is fitted to the container mouth and discharges the contents contained in the container while being inclined, and the discharge cap is suspended from the main body top surface and the main body top surface. A fitting portion that fits into the container mouth, a discharge cylinder that extends upward from the top surface of the main body and discharges the contents contained in the container, and between the inside of the container and the top surface of the main body A discharge guide portion positioned below when the discharge tube is inclined at the time of discharge, and the valve chamber communicates with the interior of the container. A supply cylinder and a bottom portion having a valve seat, and a check valve, the check valve being provided movably along the axial direction of the supply cylinder and being biased in the valve seat direction The upper surface of the check valve and the lower surface of the top surface of the main body are configured to come into contact with the valve seat. In between, there are provided at least two restricting members for restricting the movable range of the check valve, and the restricting members are centered on the central axis of the discharge cylinder from the opposite side of the direction inclined during discharge when viewed from above. As described above, the above-mentioned problems are solved by forming only in an angle range of 135 degrees in the clockwise and counterclockwise directions.

請求項1に係る吐出キャップによれば、逆止弁は供給筒の軸線方向に沿って移動可能に設けられるとともに、弁座方向に付勢されて弁座と当接可能に構成され、逆止弁の上面と本体天面の下面との間には、前記逆止弁の可動範囲を規制する少なくとも2つの規制部材が設けられているため、弁座から離脱した逆止弁を規制部材が支持することで逆止弁の可動範囲を制限でき、内容物が吐出する勢いを制限できる。
また、可動範囲を制限することで弁座からの離脱圧力の高い逆止弁を使用する必要がないため、内容物を吐出するのに過大な力を必要とせず、使用者の負担を増やすことがない。
According to the discharge cap of the first aspect, the check valve is configured to be movable along the axial direction of the supply cylinder, and is configured to be urged in the valve seat direction so as to be in contact with the valve seat. Between the upper surface of the valve and the lower surface of the top surface of the main body, there are provided at least two restricting members that restrict the movable range of the check valve, so that the restricting member supports the check valve separated from the valve seat. By doing so, the movable range of the check valve can be limited, and the momentum that the contents discharge can be limited.
In addition, since it is not necessary to use a check valve with high release pressure from the valve seat by limiting the movable range, it does not require excessive force to discharge the contents, increasing the burden on the user There is no.

また、規制部材は、上方から見て吐出時に傾斜する方向の反対から、前記吐出筒の中心軸を中心として時計回り及び反時計回り方向にそれぞれ135度ずつの角度範囲にのみ形成されているため、吐出時に傾斜した際の下方側に集中する内容物の流動を規制部材によって乱すことがなく、安定的に内容物を吐出できる。
請求項2に記載の構成によれば、規制部材は、上方から見て吐出時に傾斜する方向の反対から、前記吐出筒の中心軸を中心として時計回りに少なくとも1つ、かつ反時計回り方向に少なくとも1つ配置されているため、規制部材が逆止弁をバランスよく支持でき、逆止弁と弁座との間の流路を安定的に確保できる。
In addition, the restricting member is formed only in an angle range of 135 degrees in each of the clockwise and counterclockwise directions around the central axis of the discharge cylinder from the opposite of the direction inclined when discharging as viewed from above. The flow of the contents concentrated on the lower side when inclined at the time of discharge is not disturbed by the regulating member, and the contents can be discharged stably.
According to the configuration of claim 2, the regulating member is at least one clockwise around the central axis of the discharge cylinder and counterclockwise from the opposite of the direction inclined when discharging as viewed from above. Since at least one is arranged, the restricting member can support the check valve in a well-balanced manner, and a flow path between the check valve and the valve seat can be secured stably.

請求項3に記載の構成によれば、規制部材は、上方から見て吐出時に傾斜する方向に直交する位置に配置されているため、吐出時に傾斜した際、吐出口の下方側には規制部材が配置されることがなく、内容物の流れを乱さずにより一層安定的に吐出できる。
また、規制部材は、上方から見て吐出時に傾斜する方向に直交する位置に対称に1つずつ配置されているため、規制部材が逆止弁をより一層バランスよく支持でき、逆止弁と弁座との間の流路をさらに安定的に確保できる。
According to the configuration of the third aspect, since the regulating member is disposed at a position orthogonal to the direction inclined during discharge when viewed from above, the regulating member is disposed below the discharge port when inclined during ejection. Can be discharged more stably without disturbing the flow of the contents.
In addition, since the regulating members are arranged one by one symmetrically at a position orthogonal to the direction inclined during discharge when viewed from above, the regulating member can support the check valve in a more balanced manner. The flow path between the seats can be secured more stably.

請求項4に記載の構成によれば、規制部材は、軸方向に延びる柱状に形成されているため、規制部材が弁室の側方から延びて逆止弁を抑える構成に比べて、逆止弁から規制部材に軸方向の力で押されても、規制部材の変形量が少なく、過大な力の必要なく確実に逆止弁の可動範囲を制限することができる。
また、流路を妨げる面積が小さくなるため、内容物の流れを乱さずにより一層安定的に吐出できる。
請求項5に記載の構成によれば、弁室は、キャップ本体の係合壁部に中栓が嵌合することで形成されるため、各部の形状の設計自由度が高く、例えば、キャップ本体側のみを形状変更して規制部材の形状を変更する場合、同じ中栓を形状の異なるキャップ本体に対して使用することができる。
According to the configuration of the fourth aspect, since the regulating member is formed in a columnar shape extending in the axial direction, the regulating member extends from the side of the valve chamber to suppress the check valve. Even if the valve is pushed from the valve to the restricting member with an axial force, the amount of deformation of the restricting member is small, and the movable range of the check valve can be surely limited without the need for an excessive force.
Moreover, since the area which obstructs a flow path becomes small, it can discharge more stably without disturbing the flow of the contents.
According to the configuration described in claim 5, since the valve chamber is formed by fitting the inner plug to the engaging wall portion of the cap body, the degree of freedom in designing the shape of each portion is high. When the shape of the restricting member is changed by changing the shape of only the side, the same inner plug can be used for cap bodies having different shapes.

請求項6に記載の構成によれば、規制部材は、本体天面の下面から垂下しているため、既存の逆止弁を使用することができ、コストアップを抑制できるとともに、常に吐出筒と規制部材との位置関係が固定されるため、弁室から吐出筒までの内容物が通る流路の形成状態を安定化できる。
請求項7に記載の構成によれば、吐出キャップは、ヒンジ接続された上蓋をさらに有しているため、例えば、ヒンジ接続位置を吐出筒の中心軸から見て吐出誘導部の形成方向と反対側に設けることで、吐出方向が使用者に判別しやすく、確実に内容物の流れを乱さずに安定的に吐出できる。
According to the configuration of the sixth aspect, since the regulating member hangs from the lower surface of the top surface of the main body, the existing check valve can be used, the cost increase can be suppressed, and the discharge cylinder can always be used. Since the positional relationship with the regulating member is fixed, it is possible to stabilize the formation state of the flow path through which the contents from the valve chamber to the discharge cylinder pass.
According to the configuration described in claim 7, since the discharge cap further includes a hinge-connected upper lid, for example, when the hinge connection position is viewed from the central axis of the discharge cylinder, it is opposite to the discharge guiding portion forming direction. By providing it on the side, it is easy for the user to determine the discharge direction, and it is possible to discharge stably without disturbing the flow of the contents.

請求項8に記載の容器によれば、内容物を収容する可撓性の内部容器と、内部容器を内包する外部容器とを有した容器であって、外部容器には、内部容器と外部容器との間に外気を吸引可能な吸入弁が設けられているため、外部容器を押圧して内部容器内の圧力を高め内容物を吐出した後、外部容器の押圧を解除すると、内容物の吐出に伴い減少した外部容器内の体積を、吸入弁から外気を吸引することで補填し外部容器のみ復元することができ、使用後に内容物が少なくなった場合でも、使用前と同様の使用感で容器を押圧して逆止弁を弁座から離脱させ、内容物を吐出できる。   According to the container of Claim 8, it is a container which has the flexible inner container which accommodates the contents, and the outer container which contains an inner container, Comprising: An inner container and an outer container are included in an outer container Since an intake valve that can suck outside air is provided between the two and the outer container, the pressure inside the inner container is increased to discharge the contents after the pressure in the inner container is increased and then the contents are discharged. The volume inside the external container that has been reduced can be compensated by sucking outside air from the suction valve, and only the external container can be restored, even if the content decreases after use, with the same feeling as before use. The container can be pressed to disengage the check valve from the valve seat, and the contents can be discharged.

まず、容器200を外側から押圧すると、容器200は変形し、加圧された内容物Pが、弁座134側に付勢されている逆止弁132の弁部138を供給孔135aから押し上げ、弁部138の弁シール面138aと弁座134との間を通り、弁室130内へ流入する。
Next, the discharge operation of the contents P by the discharge cap 100 according to the present embodiment will be described with reference to FIGS.
First, when the container 200 is pressed from the outside, the container 200 is deformed, and the pressurized content P pushes up the valve portion 138 of the check valve 132 urged toward the valve seat 134 from the supply hole 135a, It passes between the valve seal surface 138 a of the valve portion 138 and the valve seat 134 and flows into the valve chamber 130.

このとき、逆止弁132の開く量は押圧力の強さによって変化するため、必要以上に容器200を押圧すると、逆止弁132の弁部138が弁座134から大きく離脱し、内容物Pが過剰に吐出されてしまう虞があるが、本発明の一実施形態に係る吐出キャップ100は、本体天面111から垂下している規制部材112によって弁部138の移動量が制限されるため、弁部138が弁座134から大きく離脱することはなく、内容物Pが過剰に吐出されることがない。   At this time, since the opening amount of the check valve 132 changes depending on the strength of the pressing force, when the container 200 is pressed more than necessary, the valve portion 138 of the check valve 132 is largely separated from the valve seat 134 and the contents P However, since the discharge cap 100 according to an embodiment of the present invention is limited in the amount of movement of the valve portion 138 by the restriction member 112 depending from the main body top surface 111, The valve portion 138 is not largely separated from the valve seat 134, and the content P is not excessively discharged.

また、規制部材112の位置によっては、弁室130内での内容物Pの流れを乱してしまい、吐出筒114から周囲に飛び散るように吐出されてしまう虞がある。
特に、吐出時の傾斜の際、内容物Pは吐出口114aよりも下方側に流れ込む量が多いため、吐出口114aよりも下方側に内容物Pの流動を妨げるような弁室130の内部構成は、吐出筒114からの内容物Pの吐出状態を悪化させやすい。
Further, depending on the position of the restricting member 112, the flow of the contents P in the valve chamber 130 may be disturbed, and there is a risk of being discharged from the discharge cylinder 114 so as to be scattered around.
In particular, since the content P flows in a lower amount than the discharge port 114a when the discharge is inclined, the internal structure of the valve chamber 130 that prevents the flow of the content P below the discharge port 114a. Tends to deteriorate the discharge state of the contents P from the discharge cylinder 114.

しかし、本発明の一実施形態に係る吐出キャップ100は、規制部材112が嵌合壁部113よりも半径方向内方側で、図3に示した状態で吐出口114aの中心と上蓋120の中心とを結んだ線を挟むように2つ設けられているため、弁部138をバランスよく支持できるとともに、弁室130内の内容物Pの流動を大きく妨げるようなことがなく、吐出筒114からの内容物Pの吐出状態を悪化させることがない。   However, in the discharge cap 100 according to an embodiment of the present invention, the regulating member 112 is located radially inward of the fitting wall portion 113, and the center of the discharge port 114a and the center of the upper lid 120 in the state shown in FIG. Are provided so as to sandwich the wire connecting the two, the valve portion 138 can be supported in a well-balanced manner, and the flow of the contents P in the valve chamber 130 is not greatly hindered from the discharge cylinder 114. The discharge state of the contents P is not deteriorated.

なお、吐出キャップ100における規制部材112の設置範囲は、図8に示すように、上方から見て吐出時に傾斜する方向の反対から、すなわち、ヒンジ接続部側から、吐出筒114の中心軸Rを回転中心として時計回り及び反時計回り方向にそれぞれ135度ずつの角度範囲内であれば内容物Pの流動への影響が少なく、好ましくは、吐出筒114の中心軸Rを回転中心として時計回り及び反時計回り方向にそれぞれ90度ずつの角度範囲内がより効果的である。
また、規制部材112はできる限り細く、角のない丸柱状のものが、内容物Pの流動への影響が少ない。
さらに、逆止弁132から規制部材112に軸方向の力で押されても、規制部材112の変形量が少なく、確実に逆止弁132の可動範囲を抑制することができる。
また、規制部材112は、本体天面111の下面から垂下しているため、既存の逆止弁132を使用することができ、コストアップを抑制できるとともに、常に吐出筒114と規制部材112との位置関係が固定されるため、弁室130から吐出筒114までの内容物Pが通る流路の形成状態を安定化できる。
As shown in FIG. 8, the installation range of the regulating member 112 in the discharge cap 100 is the center axis R of the discharge cylinder 114 from the opposite side of the direction inclined when discharging from the top, that is, from the hinge connection portion side. If the rotation center is within an angle range of 135 degrees in the clockwise and counterclockwise directions, there is little influence on the flow of the contents P, and preferably, the rotation and the clockwise rotation about the central axis R of the discharge cylinder 114 as the rotation center. An angle range of 90 degrees in the counterclockwise direction is more effective.
Further, the restriction member 112 is as thin as possible, and a round columnar shape without corners has little influence on the flow of the contents P.
Further, even if the check member 132 is pressed by the restricting member 112 with an axial force, the amount of deformation of the restricting member 112 is small, and the movable range of the check valve 132 can be reliably suppressed.
In addition, since the regulating member 112 hangs from the lower surface of the main body top surface 111, the existing check valve 132 can be used, and the cost increase can be suppressed, and the discharge cylinder 114 and the regulating member 112 are always connected. Since the positional relationship is fixed, the formation state of the flow path through which the content P from the valve chamber 130 to the discharge cylinder 114 passes can be stabilized.
