Description

本発明は、いずれも回転操作されることで脱着される構造を有して、同方向の回転操作で脱着できるようにしながら、共回りを確実に阻止することが可能な液状物収納容器に関する。   The present invention relates to a liquid storage container that has a structure that can be detached by rotating operation, and that can be reliably removed by rotating operation in the same direction, while being able to reliably prevent co-rotation.

従来、蓋がされて封止される容器本体から液体を抽出する部分に、中栓などのパーツを付加し、これらを互いに回転操作することで脱着できるようにした液状物の収納容器が知られている（特許文献１〜３参照）。   Conventionally, a liquid container has been known in which a part such as an inner plug is added to a part that extracts liquid from a container body that is sealed with a lid, and can be detached by rotating them together. (See Patent Documents 1 to 3).

特許文献１では、容器の口頸部に装着される中栓と、この中栓に装着される外蓋とを備え、中栓の内周面に雌螺条が、外周面に雄螺条が形成されるとともに、外蓋の内周面に雌螺条が、また容器の外周面に雄螺条が形成されていて、これら螺条を締め込んだり、緩めたりすることで、容器に対して中栓が、また中栓に対して外蓋が脱着されるようになっている。   In Patent Document 1, an inner plug attached to the mouth and neck portion of the container and an outer lid attached to the inner plug are provided, and a female thread is provided on the inner peripheral surface of the inner plug, and a male screw is provided on the outer peripheral surface. In addition, a female thread is formed on the inner peripheral surface of the outer lid and a male thread is formed on the outer peripheral surface of the container. By tightening or loosening these screws, The inner plug and the outer lid are detached from the inner plug.

特許文献２では、コップと中栓とがねじ嵌合され、中栓と容器の肩体とがねじ嵌合されるもので、特に共回りを防ぐために、容器に対する中栓のねじ嵌合よりも、中栓に対するコップのねじ嵌合を弱くできるように、コップと中栓のねじ嵌合の完了を凹突嵌合で分かるようにしたり、あるいはこれら２つのねじ嵌合を逆ねじとするようにしている。   In Patent Document 2, the cup and the inner plug are screw-fitted, and the inner plug and the shoulder of the container are screw-fitted. In order to weaken the screw fitting of the cup to the inner plug, the completion of the screw fitting of the cup and the inner plug can be seen by concave fitting, or these two screw fittings are made reverse screws. ing.

ところで従来にあっては、互いに回転操作される蓋や容器本体、付加したパーツなどの脱着構造に関して、逆ねじを採用したり、凹突嵌合で一方のねじ嵌合に対し他方のねじ嵌合が緩くなされるようにするなどして、共回りを防止できるようにしていたが、逆ねじは一般的な右ねじ操作に対し、逆向きの操作が要求されるため、使用する際の締め込み操作が分かりづらいなど、不便さがあった。また、凹突嵌合で２つのねじ嵌合の締め込み強さを変えるようにしても、締め込みを強くすべきねじ嵌合がしっかりと締め込まれるとは限らず、締め込みが緩めであると共回りを避けることはできないという、不都合があった。   By the way, in the past, with regard to the attachment / detachment structure of the lid, container body, and added parts that are rotated with respect to each other, a reverse screw is used, or one screw fitting is used for one screw fitting with a concave fitting. However, the reverse screw is required to operate in the opposite direction to the general right-hand screw operation. There were inconveniences such as difficult to understand operation. Further, even if the tightening strength of the two screw fittings is changed by the concave protrusion fitting, the screw fitting that should be tightened is not necessarily firmly tightened, and the tightening is loosened. There was an inconvenience that co-rotation cannot be avoided.

本発明は上記従来の課題に鑑みて創案されたものであって、いずれも回転操作されることで脱着される構造を有して、同方向の回転操作で脱着できるようにしながら、共回りを確実に阻止することが可能な液状物収納容器を提供することを目的とする。   The present invention has been devised in view of the above-described conventional problems, and each has a structure that can be detached by rotating operation, and can be detached by rotating operation in the same direction. It is an object of the present invention to provide a liquid storage container that can be reliably blocked.

本発明にかかる液状物収納容器は、液状物を抽出可能に収納する容器本体と、抽出口を有して、上記容器本体に第１ネジ部を介して締め緩め自在に螺合される抽出筒と、該抽出筒と上記容器本体との間に設けられ、これらを係脱可能に係止する係止部と、上記抽出口を封鎖すべく上記抽出筒に第２ネジ部を介して締め緩め自在に螺合されるとともに、上記係止部による係止状態を、該抽出筒への締め込み状態で保持し、該抽出筒から緩めていく過程で離脱可能状態とするキャップとを備えたことを特徴とする。   The liquid container according to the present invention includes a container main body for storing a liquid substance in an extractable manner, and an extraction cylinder that has an extraction port and is screwed to the container main body via a first screw portion so as to be loosened and loosened. And a locking portion that is provided between the extraction cylinder and the container main body and detachably engages with the extraction cylinder, and is tightened and loosened to the extraction cylinder via a second screw portion to seal the extraction port. A cap that is freely screwed and that holds the locked state by the locking portion in a tightened state to the extraction cylinder and is detachable in the process of loosening from the extraction cylinder. It is characterized by.

本発明にかかる液状物収納容器にあっては、いずれも回転操作されることで脱着される構造を有して、同方向の回転操作で脱着できるようにしながら、共回りを確実に阻止することができる。   In the liquid container according to the present invention, all have a structure that can be detached by rotating operation, and can be reliably detached by rotating operation in the same direction, while reliably preventing co-rotation. Can do.

以下に、本発明にかかる液状物収納容器の好適な一実施形態を、添付図面を参照して詳細に説明する。本実施形態にかかる液状物収納容器は基本的には、図１〜図４に示すように、液状物を抽出可能に収納する容器本体１と、抽出口２を有して、容器本体１に第１ネジ部３を介して締め緩め自在に螺合される抽出筒４と、抽出筒４と容器本体１との間に設けられ、これらを係脱可能に係止する係止部５と、抽出口２を封鎖すべく抽出筒４に第２ネジ部６を介して締め緩め自在に螺合されるとともに、係止部５による係止状態を、抽出筒４への締め込み状態で保持し、抽出筒４から緩めていく過程で離脱可能状態とするキャップ７とを備えて構成される。   Hereinafter, a preferred embodiment of a liquid container according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 4, the liquid material storage container according to the present embodiment basically includes a container body 1 that stores liquid material in an extractable manner and an extraction port 2. An extraction cylinder 4 that is screwed together so as to be loosened and tightened via the first screw part 3, and a locking part 5 that is provided between the extraction cylinder 4 and the container main body 1 and that detachably locks them. In order to seal the extraction port 2, the extraction tube 4 is screwed into the extraction tube 4 via the second screw portion 6 so as to be loosened and loosened, and the locked state by the locking portion 5 is held in the tightened state to the extraction tube 4. , And a cap 7 that can be detached in the process of loosening from the extraction cylinder 4.

容器本体１は底部が封鎖された中空筒体状に形成され、その内部に、例えばローションやミルクなどの液状化粧料などの液状物が収納される。容器本体１には、その上端部に上下２つの第１段差部８と第２段差部９を介して、最上部に抽出首部１０が、そしてまたその下方に縮径部１１が形成され、抽出首部１０には液状物を抽出可能とする開口１２が形成される。他方、抽出筒４は、上端が天面部１３で封鎖された中空筒体状に形成されるとともに、一つの段差部１４を介して、下方に環状スカート部１５が、上方に筒部１６が形成される。天面部１３には、その中央に抽出口２が、抽出口２周囲に上方へ突出させて環状の注ぎ口部１７が、また下方へ垂下させて容器本体１の開口１２に嵌脱自在に嵌め込まれる環状嵌合部１８が形成される。この抽出筒４は、その段差部１４が容器本体１の第１段差部８に重ね合わされて、筒部１６が抽出首部１０に、また環状スカート部１５が縮径部１１に被さるようにして、容器本体１に装着される。   The container main body 1 is formed in a hollow cylindrical shape whose bottom is sealed, and a liquid material such as a liquid cosmetic such as lotion or milk is accommodated therein. The container body 1 is formed with an extraction neck 10 at the top and a reduced diameter portion 11 at the top, with two upper and lower first step portions 8 and 9 at the upper end thereof. The neck 10 is formed with an opening 12 that can extract a liquid material. On the other hand, the extraction cylinder 4 is formed in the shape of a hollow cylinder whose upper end is sealed by the top surface part 13, and the annular skirt part 15 is formed below and the cylinder part 16 is formed above via a single step part 14. Is done. The top surface portion 13 has an extraction port 2 at the center thereof, protrudes upward around the extraction port 2, and an annular spout portion 17 hangs downward and removably fits into the opening 12 of the container body 1. An annular fitting portion 18 is formed. The extraction cylinder 4 has its stepped portion 14 overlapped with the first stepped portion 8 of the container body 1 so that the cylinder portion 16 covers the extraction neck portion 10 and the annular skirt portion 15 covers the reduced diameter portion 11. Mounted on the container body 1.

容器本体１と抽出筒４との間には第１ネジ部３が形成される。具体的には、容器本体１の抽出首部１０の外周面には第１雄ネジ３ａが形成されるとともに、抽出筒４の筒部１６の内周面には、第１雄ネジ３ａに締め緩め自在に螺合される第１雌ネジ３ｂが形成され、これにより抽出筒４が容器本体１に着脱自在に装着される。   A first screw portion 3 is formed between the container body 1 and the extraction cylinder 4. Specifically, a first male screw 3 a is formed on the outer peripheral surface of the extraction neck portion 10 of the container body 1, and the first male screw 3 a is tightened and loosened on the inner peripheral surface of the tube portion 16 of the extraction tube 4. A first female screw 3 b that is freely screwed is formed, whereby the extraction cylinder 4 is detachably attached to the container body 1.

係止部５は容器本体１の抽出首部１０と抽出筒４の筒部１６との間に、これらを係脱可能に係止すべく設けられる。係止部５は、抽出首部１０の外周面に径方向外方へ向かって突出させて形成された凸部１９と、筒部１６の内周面に、その径方向内方へ向かって突出させて形成され、凸部１９に係脱可能に係止される係止突起２０とから構成される。凸部１９は、容器本体１の第１段差部８直上であって、第１雄ネジ３ａの下方となる抽出首部１０の下端に形成された環状段部２１に設けられる。また係止突起２０は、抽出筒４の段差部１４直上であって環状段部２１と向かい合う筒部１６の下端に形成される弾性片２２に設けられる。弾性片２２は、筒部１６に形成されたＵ字状のスリット２３により、筒部１６の径方向に弾性変形自在に形成される。   The locking portion 5 is provided between the extraction neck portion 10 of the container body 1 and the cylindrical portion 16 of the extraction tube 4 so as to be detachably locked. The locking portion 5 is protruded radially inward from the outer peripheral surface of the extraction neck portion 10 and protruded radially outward from the convex portion 19 and the inner peripheral surface of the cylindrical portion 16. And a locking projection 20 that is detachably locked to the convex portion 19. The convex part 19 is provided in the annular step part 21 formed in the lower end of the extraction neck part 10 just above the 1st level | step-difference part 8 of the container main body 1 and the downward direction of the 1st external thread 3a. The locking projection 20 is provided on an elastic piece 22 formed on the lower end of the cylindrical portion 16 that is directly above the stepped portion 14 of the extraction tube 4 and faces the annular stepped portion 21. The elastic piece 22 is formed to be elastically deformable in the radial direction of the cylindrical portion 16 by a U-shaped slit 23 formed in the cylindrical portion 16.

そしてこの係止部５は、第１ネジ部３を介して筒部１６を抽出首部１０に締め込むことにより、係止突起２０が弾性片２２の弾性変形を伴って凸部１９を乗り越えて係止され、これにより抽出筒４と容器本体１との相対回転、特に第１ネジ部３の緩み方向への相対回転を阻止するようになっている。他方、弾性片２２の弾性変形を伴って係止突起２０が凸部１９を乗り越える操作力を加えて抽出筒４を緩めると、係止突起２０は凸部１９から離脱されることとなり、これにより抽出筒４を容器本体１から取り外すことができるようになっている。   And this latching | locking part 5 fastens the cylinder part 16 to the extraction neck part 10 via the 1st screw part 3, and the latching protrusion 20 gets over the convex part 19 with the elastic deformation of the elastic piece 22, and is engaged. Thus, the relative rotation between the extraction cylinder 4 and the container body 1, particularly the relative rotation in the loosening direction of the first screw portion 3 is prevented. On the other hand, if the extraction projection 4 is loosened by applying an operating force that the locking projection 20 gets over the convex portion 19 with the elastic deformation of the elastic piece 22, the locking projection 20 is detached from the convex portion 19. The extraction cylinder 4 can be removed from the container body 1.

図示例にあっては、凸部１９および係止突起２０は、抽出首部１０の周方向に１８０°の間隔を隔てて２箇所に形成されている。しかしながら、その設置箇所数は適宜に設定することができる。また、抽出首部１０に筒部１６を締め込んでいく（第１ネジ部３は右ネジで抽出筒４が右へ回される）際に、係止突起２０と向かい合うようになる凸部１９には、係止突起２０が弾性片２２の弾性変形を伴って円滑にこれを乗り越えることができるように傾斜面２４が形成される。   In the example of illustration, the convex part 19 and the latching protrusion 20 are formed in two places at intervals of 180 degrees in the circumferential direction of the extraction neck part 10. However, the number of installation locations can be set as appropriate. Further, when the cylindrical portion 16 is tightened to the extraction neck 10 (the first screw portion 3 is rotated to the right by the right screw), the convex portion 19 that faces the locking projection 20 is formed. The inclined surface 24 is formed so that the locking projection 20 can smoothly get over the elastic piece 22 with the elastic deformation of the elastic piece 22.

さらに、環状段部２１には、係止突起２０が凸部１９に係止された後に筒部１６が抽出首部１０周りにがたつくことを防止するために、凸部１９に対し適宜な間隔を隔てて向かい合わせて係止突起２０を当該凸部１９との間に挟み込む制止凸部２５が形成されている。この制止凸部２５は、第１ネジ部３を締め切った位置で係止突起２０が凸部１９を乗り越える寸法設定とすれば、係止突起２０、ひいては抽出筒４ががたつくことはないので、必要に応じて設ければよい。   Further, the annular step portion 21 is spaced at an appropriate interval from the convex portion 19 in order to prevent the cylindrical portion 16 from rattling around the extraction neck portion 10 after the locking projection 20 is locked to the convex portion 19. A restraining convex portion 25 is formed so as to face each other and sandwich the locking projection 20 between the convex portion 19. The restraining projection 25 is necessary because the latching projection 20 and thus the extraction tube 4 do not rattle if the latching projection 20 is sized so as to get over the projection 19 at the position where the first screw portion 3 is closed. It may be provided according to.

キャップ７は、周側壁部２６と天板部２７とから上端が封鎖された中空筒体状に形成される。このキャップ７にはその天板部２７から垂下させて、内側に抽出口２を封鎖すべく注ぎ口部１７内方に挿抜自在に挿入される栓部２８が、外側に抽出筒４の天面部１３に当接される環状シール２９が形成される。キャップ７と抽出筒４との間には、第１ネジ部３と同じ右ネジとされた第２ネジ部６が形成される。具体的には、キャップ７の周側壁部２６の内周面には第２雌ネジ６ａが形成されるとともに、抽出筒４の筒部１６の外周面には、第２雌ネジ６ａに締め緩め自在に螺合される第２雄ネジ６ｂが形成され、これによりキャップ７が抽出筒４に着脱自在に装着される。   The cap 7 is formed in a hollow cylindrical shape whose upper end is sealed from the peripheral side wall portion 26 and the top plate portion 27. The cap 7 hangs down from the top plate portion 27 and has a plug portion 28 that is detachably inserted into the spout portion 17 in order to seal the extraction port 2 on the inside, and the top surface portion of the extraction tube 4 on the outside. 13 is formed. Between the cap 7 and the extraction cylinder 4, a second screw portion 6 that is the same right screw as the first screw portion 3 is formed. Specifically, the second female screw 6a is formed on the inner peripheral surface of the peripheral side wall portion 26 of the cap 7, and the second female screw 6a is tightened and loosened on the outer peripheral surface of the tube portion 16 of the extraction tube 4. A second male screw 6b that is freely screwed is formed, whereby the cap 7 is detachably attached to the extraction tube 4.

特にこのキャップ７の周側壁部２６は、栓部２８が抽出筒４の注ぎ口部１７内に入り込み、環状シール２９が天面部１３に当接するキャップ７の抽出筒４への装着状態で、弾性片２２が形成された筒部２６の下端を覆って被さる高さ寸法で形成され、これによりキャップ７は、抽出筒４への締め込み状態で弾性片２２の弾性変形を阻止し、他方、抽出筒４から緩められていく過程で弾性片２２よりも上方へと抜き出されることで、弾性片２２の弾性変形を許容するようになっている。   In particular, the peripheral side wall portion 26 of the cap 7 is elastic when the cap portion 28 enters the spout portion 17 of the extraction tube 4 and the annular seal 29 contacts the top surface portion 13 and is attached to the extraction tube 4. The cap 22 is formed with a height that covers and covers the lower end of the cylindrical portion 26 on which the piece 22 is formed, whereby the cap 7 prevents elastic deformation of the elastic piece 22 in a state of being tightened to the extraction cylinder 4, and on the other hand, extraction The elastic piece 22 is allowed to be elastically deformed by being pulled upward from the elastic piece 22 in the process of being loosened from the cylinder 4.

詳細には、第１ネジ部３により抽出筒４が容器本体１に螺着されて係止突起２０が凸部１９に係止されている状態で、第２ネジ部６によりキャップ７が抽出筒４の筒部１６に螺着されているときには、キャップ７の周側壁部２６が弾性片２２の外側を覆っていて、これにより弾性片２２の弾性変形が阻止されて、係止部５はその離脱が阻止された係止状態に保持される。第２ネジ部６によりキャップ７を緩めて離脱させていく過程では、緩め始めた段階では、キャップ７の周側壁部２６は依然として弾性片２２に被さっていて、係止部５による抽出筒４と容器本体１の係止状態が保持され、キャップ７のみを抽出筒４から緩めていくことができる。キャップ７が相当に緩んだ段階になると、周側壁部２６は弾性片２２上方に達し、弾性片２２が弾性変形可能となって容器本体１と抽出筒４を係止している係止部５は離脱可能状態とされるようになっている。   Specifically, in the state where the extraction cylinder 4 is screwed to the container body 1 by the first screw portion 3 and the locking projection 20 is locked to the convex portion 19, the cap 7 is extracted by the second screw portion 6. 4, the peripheral side wall portion 26 of the cap 7 covers the outside of the elastic piece 22, thereby preventing the elastic piece 22 from being elastically deformed. It is held in a locked state in which separation is prevented. In the process of loosening and releasing the cap 7 by the second screw portion 6, the peripheral side wall portion 26 of the cap 7 is still covered with the elastic piece 22 at the stage of starting to loosen. The locked state of the container body 1 is maintained, and only the cap 7 can be loosened from the extraction cylinder 4. When the cap 7 is in a considerably loosened stage, the peripheral side wall portion 26 reaches above the elastic piece 22, and the elastic piece 22 can be elastically deformed to lock the container body 1 and the extraction tube 4. Is supposed to be in a detachable state.

本実施形態に係る液状物収納容器の作用について説明すると、容器本体１に抽出筒４が螺合され、さらに抽出筒４にキャップ７が螺合された状態の液状物収納容器から液状物を抽出する際には、第２ネジ部６を介してキャップ７を取り外す。この際、緩め始めはキャップ７により係止部５の係止状態を保持することができるので、第２ネジ部６と同じ向きのネジである第１ネジ部３における抽出筒４と容器本体１との相対回転、すなわち第１ネジ部３に緩みが生じることを防止でき、第２ネジ部６のみの螺合解除によりキャップ７だけを抽出筒４、ひいては容器本体１からスムーズに取り外すことができる。   The operation of the liquid material storage container according to the present embodiment will be described. The liquid material is extracted from the liquid material storage container in which the extraction cylinder 4 is screwed to the container body 1 and the cap 7 is screwed to the extraction cylinder 4. When doing so, the cap 7 is removed via the second screw portion 6. At this time, since the locking state of the locking portion 5 can be held by the cap 7 at the beginning of loosening, the extraction cylinder 4 and the container body 1 in the first screw portion 3 which is a screw in the same direction as the second screw portion 6. , That is, loosening of the first screw portion 3 can be prevented, and only the cap 7 can be smoothly removed from the extraction tube 4 and thus the container body 1 by releasing the screwing of only the second screw portion 6. .

詳しくは、第２ネジ部６の緩め始めでは、キャップ７により弾性片２２の弾性変形が阻止されていて、これにより係止部５は係止状態にあって第１ネジ部３が緩むことはなく、その後、キャップ７が相当に緩められた時点では、弾性片２２の弾性変形が許容されるようになって係止部５は離脱可能状態になるけれども、このときには既に第２ネジ部６を軽い操作力で緩めることができるようになっていて、第２ネジ部６の回転操作によって係止部５が離脱して第１ネジ部３が緩んでしまうことはなく、抽出筒４の容器本体１への装着状態を保持することができる。そしてキャップ７を取り外すことにより、容器本体１に対して装着状態にある抽出筒４の抽出口２から液状物を抽出することができる。抽出後は、キャップ７を第２ネジ部６を介して抽出筒４に螺合していけば、係止部５の離脱や第１ネジ部３の緩みを生じることなく、装着することができて、適切に抽出口２を封鎖することができる。   Specifically, at the beginning of the loosening of the second screw portion 6, the elastic deformation of the elastic piece 22 is prevented by the cap 7, so that the locking portion 5 is locked and the first screw portion 3 is loosened. After that, when the cap 7 is considerably loosened, the elastic piece 22 is allowed to be elastically deformed, and the locking portion 5 is in a detachable state. The container body of the extraction cylinder 4 can be loosened with a light operating force, and the locking portion 5 is not detached by the rotation operation of the second screw portion 6 and the first screw portion 3 is not loosened. 1 can be held. Then, by removing the cap 7, it is possible to extract the liquid material from the extraction port 2 of the extraction cylinder 4 that is attached to the container body 1. After the extraction, if the cap 7 is screwed into the extraction cylinder 4 via the second screw portion 6, it can be attached without causing the locking portion 5 to be detached or the first screw portion 3 to be loosened. Thus, the extraction port 2 can be properly sealed.

他方、容器本体１内に液状物を収納したり、補充する際には、キャップ７を取り外した状態で、抽出筒４を容器本体１に対して第１ネジ部３の緩み方向に回転させればよい。これにより、係止突起２０が弾性片２２の弾性変形を伴いつつ凸部１９から離脱して係止部５の係止状態を解除することができ、抽出筒４を第１ネジ部３を介して容器本体１から取り外すことができて、抽出首部１０の開口１２から液状物を補充など、することができる。液状物を補充などした後は、第１ネジ部３により抽出筒４を容器本体１に螺合していき、凸部１９にこれを乗り越えさせて係止突起２０を係止すればよい。そしてその後、キャップ７を抽出筒４に装着する。   On the other hand, when storing or replenishing a liquid substance in the container body 1, the extraction cylinder 4 can be rotated in the loosening direction of the first screw part 3 with respect to the container body 1 with the cap 7 removed. That's fine. As a result, the locking projection 20 can be released from the convex portion 19 with elastic deformation of the elastic piece 22 to release the locking state of the locking portion 5, and the extraction cylinder 4 can be released via the first screw portion 3. It can be removed from the container body 1 and the liquid material can be replenished from the opening 12 of the extraction neck 10. After the liquid material is replenished, the extraction cylinder 4 is screwed into the container main body 1 by the first screw portion 3, and the protrusion 19 is passed over the locking projection 20 to be locked. Thereafter, the cap 7 is attached to the extraction cylinder 4.

以上説明したように本実施形態に係る液状物収納容器にあっては、液状物を抽出可能に収納する容器本体１と、抽出口２を有して、容器本体１に第１ネジ部３を介して締め緩め自在に螺合される抽出筒４と、抽出筒４と容器本体１との間に設けられ、これらを係脱可能に係止する係止部５と、抽出口２を封鎖すべく抽出筒４に第２ネジ部６を介して締め緩め自在に螺合されるとともに、係止部５による係止状態を、抽出筒４への締め込み状態で保持し、抽出筒４から緩めていく過程で離脱可能状態とするキャップ７とを備えたので、係止部５による容器本体１と抽出筒４との係止状態を、締め緩めされるキャップ７で保持したり解除可能にしたりして２つのネジ部３，６の共回りを確実に阻止することができ、これにより容器本体１への抽出筒４の脱着も、抽出筒４へのキャップ７の脱着も、ともに同方向の回転操作で行うことができて、便利で良好な操作性を確保することができる。   As described above, the liquid material storage container according to the present embodiment has the container body 1 that stores the liquid material in an extractable manner and the extraction port 2, and the container body 1 has the first screw portion 3. The extraction cylinder 4 that is screwed to be freely tightened and loosened, a locking portion 5 that is provided between the extraction cylinder 4 and the container body 1 and that can be detachably locked, and the extraction port 2 are sealed. The extraction tube 4 is screwed to the extraction tube 4 through the second screw portion 6 so as to be loosened and loosened, and the locked state by the locking portion 5 is held in the tightened state to the extraction tube 4 and is loosened from the extraction tube 4. Since the cap 7 is provided so that it can be removed in the course of the process, the locking state between the container body 1 and the extraction tube 4 by the locking portion 5 can be held or released by the cap 7 that is tightened or loosened. Thus, it is possible to reliably prevent the two screw parts 3 and 6 from co-rotating, thereby extracting the container body 1 4 of desorption, nor desorption of the cap 7 to the extraction tube 4, and can be carried out in both the rotating operation in the same direction, it is possible to ensure convenient and good operability.

このような構成を備えた液状物収納容器は、液状物を直接入れ替える入れ替え式であるので、交換用のレフィルなどの別容器を容器本体１に脱着する形態のものに比べて、省資源化に適している。また、容器本体１をガラス製とし、抽出筒４を合成樹脂製とした場合など、異種材料で構成した場合に、抽出筒４を容器本体１から容易に取り外すことができて、分別収集に対し高い適応性を発揮することができる。   Since the liquid material storage container having such a configuration is a replacement type in which the liquid material is directly replaced, it is possible to save resources as compared with a configuration in which another container such as a refill for replacement is attached to and detached from the container body 1. Are suitable. In addition, when the container body 1 is made of glass and the extraction cylinder 4 is made of a synthetic resin, the extraction cylinder 4 can be easily detached from the container body 1 and can be separated. High adaptability can be demonstrated.
