本発明の一実施形態の吐出容器の使用開始前の状態を示す縦断面図である。FIG. 2 is a vertical cross-sectional view showing a state before starting to use the discharge container of the embodiment of the present invention. 図１に示す吐出具本体が使用位置にある時に係合位置にある回り止め部を破線で示し、非係合位置にある回り止め部を実線で示す縦断面図である。2 is a vertical cross-sectional view showing, when the dispenser body shown in FIG. 1 is in the use position, a rotation-stopping portion in an engaged position is shown by a broken line, and a rotation-stopping portion in a non-engaged position is shown by a solid line.
　以下、図面を参照しつつ本発明の実施形態を例示説明する。 Below, an embodiment of the present invention will be described with reference to the drawings.
　図１～図２に示すように、本発明の一実施形態において吐出容器１は、口部周壁２ａと被係合部２ｂとを有する容器本体２と、吐出具本体３ａと回り止め部３ｂとを有する吐出具３とを有し、回り止め部３ｂは係合部４を有する。口部周壁２ａは中心軸線Ｏを中心とする筒状をなす。 As shown in Figures 1 and 2, in one embodiment of the present invention, a discharge container 1 has a container body 2 having a peripheral wall 2a of the mouth and an engaged portion 2b, and a discharge tool 3 having a discharge tool body 3a and a rotation prevention portion 3b, and the rotation prevention portion 3b has an engagement portion 4. The peripheral wall 2a of the mouth is cylindrical and centered on a central axis O.
　なお、本実施形態において、軸方向は中心軸線Ｏに沿う方向であり、径方向は中心軸線Ｏに直交する方向であり、周方向は中心軸線Ｏを周回する方向であり、縦断面は中心軸線Ｏを含む断面である。説明の便宜上、軸方向に沿って口部周壁２ａから容器本体２の内部へ向かう側を下方といい、その反対方向を上方という。 In this embodiment, the axial direction is the direction along the central axis O, the radial direction is the direction perpendicular to the central axis O, the circumferential direction is the direction going around the central axis O, and the longitudinal section is a section including the central axis O. For ease of explanation, the side going from the mouth peripheral wall 2a toward the inside of the container body 2 along the axial direction is referred to as the lower side, and the opposite direction is referred to as the upper side.
　吐出具本体３ａは、口部周壁２ａに対して、容器本体２の内容物を吐出するための図２に示す使用位置に螺合によって取り付け可能であり、使用位置で螺合した状態から螺脱によって取り外し可能である。 The dispenser body 3a can be attached by screwing to the mouth peripheral wall 2a in the use position shown in FIG. 2 for discharging the contents of the container body 2, and can be removed by unscrewing from the screwed state in the use position.
　回り止め部３ｂは、吐出具本体３ａが使用位置にある時に、係合部４が口部周壁２ａに対する吐出具本体３ａの螺脱方向の回転を規制するように被係合部２ｂに凹凸同士の噛み合いによって係合する図２に二点鎖線で示す係合位置と、係合部４が被係合部２ｂに係合しない図２に実線で示す非係合位置との間で、少なくとも係合位置から非係合位置に、口部周壁２ａの軸方向に、回り止め部３ｂに対する軸方向へのスライド操作に応じて移動可能である。 When the dispenser body 3a is in the use position, the anti-rotation portion 3b can move in the axial direction of the mouth wall 2a in response to a sliding operation of the anti-rotation portion 3b in the axial direction at least from the engaged position to the non-engaged position, between an engaged position shown by a two-dot chain line in FIG. 2 where the engaging portion 4 engages with the engaged portion 2b by meshing of the projections and recesses so as to restrict rotation of the dispenser body 3a in the screw-unscrewing direction relative to the mouth wall 2a, and a non-engaged position shown by a solid line in FIG. 2 where the engaging portion 4 does not engage with the engaged portion 2b.
　このような構成によれば、吐出具本体３ａが使用位置にある時に回り止め部３ｂを係合位置に配置しておくことにより、吐出具本体３ａの容器本体２からの意図しない螺脱を規制できる。 With this configuration, by placing the anti-rotation portion 3b in the engagement position when the dispenser body 3a is in the use position, it is possible to prevent the dispenser body 3a from unintentionally unscrewing from the container body 2.
　また、吐出具３と容器本体２を分別廃棄する時など、吐出具本体３ａを口部周壁２ａから取り外す必要がある時は、吐出具本体３ａが使用位置にある状態で、回り止め部３ｂを上方へスライド操作して非係合位置に移動させ、螺脱方向に回転操作することで、吐出具本体３ａを口部周壁２ａから螺脱させて容易に取り外すことができる。 In addition, when it is necessary to remove the dispenser body 3a from the peripheral wall 2a of the mouth, such as when the dispenser 3 and the container body 2 are to be disposed of separately, the anti-rotation portion 3b can be slid upward to the disengagement position while the dispenser body 3a is in the use position, and then rotated in the unscrewing direction to unscrew the dispenser body 3a from the peripheral wall 2a and easily removed.
　なお、被係合部２ｂと係合部４の構成としては、例えば、吐出具本体３ａが使用位置にある時に、回り止め部３ｂが係合位置にある時は係合部４が被係合部２ｂに対し、吐出具本体３ａの螺脱と同じ回転方向に相対回転を規制されるようにラチェット部を介して係合する構成を採用できる。 The configuration of the engaged portion 2b and the engaging portion 4 can be such that, for example, when the dispenser body 3a is in the use position and the anti-rotation portion 3b is in the engaged position, the engaging portion 4 engages with the engaged portion 2b via a ratchet portion so that relative rotation is restricted in the same rotational direction as the dispenser body 3a is unscrewed.
　回り止め部３ｂは、吐出具本体３ａが使用位置にある時に、回り止め部３ｂに対する上方へのスライド操作に応じて係合位置から非係合位置に移動可能であり、且つ、回り止め部３ｂに対する下方へのスライド操作に応じて非係合位置から係合位置に移動可能である。 When the dispenser body 3a is in the use position, the anti-rotation portion 3b can be moved from the engaged position to the disengaged position in response to an upward sliding operation of the anti-rotation portion 3b, and can be moved from the disengaged position to the engaged position in response to a downward sliding operation of the anti-rotation portion 3b.
　このような構成によれば、吐出具３を他の容器本体２に付け替える時などに、吐出具本体３ａを使用位置に配置し、回り止め部３ｂを下方へスライド操作して非係合位置から係合位置に移動させることで、吐出具本体３ａを口部周壁２ａに取り付け、吐出具本体３ａの容器本体２からの意図しない螺脱を規制できる状態にすることができる。また、被係合部２ｂと係合部４の構成として、上記のラチェット部に限らず、例えば、吐出具本体３ａが使用位置にある時に、回り止め部３ｂが係合位置にある時は被係合部２ｂと係合部４が互いに周方向の両側に相対回転を規制されるように（例えばスプライン部を介して）係合する構成を採用することもできる。しかし、回り止め部３ｂはこのような構成に限らない。 With this configuration, when replacing the dispenser 3 with another container body 2, the dispenser body 3a can be placed in the use position and the anti-rotation portion 3b can be slid downward to move it from the non-engaged position to the engaged position, thereby attaching the dispenser body 3a to the mouth peripheral wall 2a and preventing the dispenser body 3a from being unintentionally unscrewed from the container body 2. The configuration of the engaged portion 2b and the engaging portion 4 is not limited to the ratchet portion described above, and it is also possible to adopt a configuration in which, for example, when the dispenser body 3a is in the use position and the anti-rotation portion 3b is in the engaged position, the engaged portion 2b and the engaging portion 4 engage with each other (e.g., via a spline portion) so that relative rotation on both sides in the circumferential direction is restricted. However, the anti-rotation portion 3b is not limited to this configuration.
　図１に示すように、吐出具３は、口部周壁２ａからの吐出具本体３ａの螺脱と同じ回転方向の、第２螺合部６を介した螺脱によって吐出具本体３ａから取り外し可能なキャップ３ｃを有する。 As shown in FIG. 1, the dispenser 3 has a cap 3c that can be removed from the dispenser body 3a by unscrewing it via the second screw portion 6 in the same rotational direction as the dispenser body 3a is unscrewed from the mouth peripheral wall 2a.
　このような構成によれば、吐出具本体３ａが図２に示す使用位置にある時に、回り止め部３ｂを係合位置に配置しておけば吐出具本体３ａが共回りしないので、キャップ３ｃを螺合、螺脱によって容易に吐出具本体３ａに着脱することができる。 With this configuration, if the anti-rotation portion 3b is placed in the engagement position when the dispenser body 3a is in the use position shown in Figure 2, the dispenser body 3a will not rotate with the anti-rotation portion 3b, so the cap 3c can be easily attached to and detached from the dispenser body 3a by screwing and unscrewing it.
　しかし、キャップ３ｃの構成はこれに限らない。また、キャップ３ｃを有さない構成としてもよい。 However, the configuration of the cap 3c is not limited to this. It may also be configured without the cap 3c.
　吐出具本体３ａは、装着筒７ａを有し、装着筒７ａによって口部周壁２ａに対して使用位置から螺脱によって取り外し可能であり、回り止め部３ｂは、装着筒７ａに、周方向の両側に相対回転を規制され且つ軸方向の両側に相対移動を許容されるように、例えばスプライン部を介して、連結する。 The dispenser body 3a has an attachment tube 7a, which can be removed from the use position relative to the mouth peripheral wall 2a by unscrewing it, and the anti-rotation portion 3b is connected to the attachment tube 7a, for example via a spline portion, so that relative rotation is restricted on both sides in the circumferential direction and relative movement is permitted on both sides in the axial direction.
　このような構成によれば、上述したような、回り止め部３ｂは、吐出具本体３ａが使用位置にある時に、回り止め部３ｂに対する上方へのスライド操作に応じて係合位置から非係合位置に移動可能であり、且つ、回り止め部３ｂに対する下方へのスライド操作に応じて非係合位置から係合位置に移動可能である構成を簡単な構造で実現できる。しかし、吐出具本体３ａと回り止め部３ｂの構成はこれに限らない。 With this configuration, the anti-rotation portion 3b can be moved from the engaged position to the disengaged position in response to an upward sliding operation of the anti-rotation portion 3b when the dispenser body 3a is in the use position, and can be moved from the disengaged position to the engaged position in response to a downward sliding operation of the anti-rotation portion 3b, as described above, with a simple structure. However, the configuration of the dispenser body 3a and the anti-rotation portion 3b is not limited to this.
　吐出具本体３ａは、口部周壁２ａに対して図１に示す仮保持位置に取り付け可能であり、突き当て部７ｂを有し、突き当て部７ｂは、仮保持位置から使用位置まで吐出具本体３ａを移動させる操作によって口部周壁２ａの径方向内側で容器本体２の内側へ移動することで容器本体２の封止部材２ｃに突き当たることにより、図２に示すように容器本体２を開封する。また、吐出具３は、仮保持位置から使用位置までの吐出具本体３ａの移動を（例えば、図１に示すように軸方向において回り止め部３ｂと容器本体２との間に挟まることで）規制する図１に示す開封規制位置から除去可能な、例えば軸方向に見てＣ字形状をなし弾性変形可能な、図１に示すストッパ３ｄを有する。 The dispenser body 3a can be attached to the mouth peripheral wall 2a at the temporary holding position shown in Fig. 1, and has an abutment part 7b, which moves radially inside the mouth peripheral wall 2a toward the inside of the container body 2 by moving the dispenser body 3a from the temporary holding position to the use position, and abuts against the sealing member 2c of the container body 2, thereby opening the container body 2 as shown in Fig. 2. The dispenser 3 also has a stopper 3d shown in Fig. 1, which is, for example, C-shaped when viewed in the axial direction and elastically deformable and can be removed from the unsealing restricting position shown in Fig. 1, which restricts the movement of the dispenser body 3a from the temporary holding position to the use position (for example, by being sandwiched between the rotation stopper part 3b and the container body 2 in the axial direction as shown in Fig. 1).
　このような構成によれば、ストッパ３ｄによって容器本体２の不意の開封を抑制することができ、また、ストッパ３ｄを開封規制位置から除去した後に吐出具本体３ａを仮保持位置から使用位置まで移動させる簡単な操作により、容器本体２を開封し、使用できる状態にすることができる。しかし、吐出容器１の構成はこれに限らない。 With this configuration, the stopper 3d can prevent the container body 2 from being accidentally opened, and the container body 2 can be opened and made usable by a simple operation of removing the stopper 3d from the opening restriction position and then moving the dispenser body 3a from the temporary holding position to the use position. However, the configuration of the dispenser container 1 is not limited to this.
　封止部材２ｃは口部周壁２ａを閉塞するシート状をなし、突き当て部７ｂは封止部材２ｃに突き当たることにより、封止部材２ｃを破断させることで容器本体２を開封する。このような構成によれば、構造の簡素化を実現できる。しかし吐出容器１の構成はこれに限らない。 The sealing member 2c is in the form of a sheet that closes the peripheral wall 2a of the mouth portion, and the abutting portion 7b abuts against the sealing member 2c, thereby breaking the sealing member 2c and opening the container body 2. This configuration allows for a simplified structure. However, the configuration of the discharge container 1 is not limited to this.
　封止部材２ｃは、容器本体２の最も内層側に設けられる最内層体に一体に設けられる。このような構成によれば、最内層体を例えばアルミなどによって形成することにより、最内層体によってバリア性、遮光性などの機能を効率的に高めることができる。 The sealing member 2c is integrally provided with the innermost layer, which is provided on the innermost side of the container body 2. With this configuration, by forming the innermost layer from, for example, aluminum, the innermost layer can efficiently improve functions such as barrier properties and light blocking properties.
　吐出具本体３ａは、容器本体２内からの流出を許容し且つその逆の流入を抑制する弁体８ａを有する。このような構成によれば、使用時に容器本体２内の内容物を外気に晒されにくくできるので、内容物の品質を良好に維持できる。しかし、吐出具本体３ａの構成はこれに限らない。 The dispenser body 3a has a valve body 8a that allows outflow from the container body 2 and prevents inflow in the opposite direction. With this configuration, the contents in the container body 2 are less likely to be exposed to the outside air during use, so the quality of the contents can be well maintained. However, the configuration of the dispenser body 3a is not limited to this.
　吐出具本体３ａは、装着筒７ａと突き当て部７ｂを有し且つキャップ３ｃに第２螺合部６を介して螺合可能な装着部材７と、吐出具本体３ａが使用位置にある時に装着部材７と口部周壁２ａの間に軸方向に挟まれるパッキン９と、弁体８ａを有する弁部材８と、吐出口１０ａを有するノズル部材１０との組み立て構造を有する。しかし、吐出具本体３ａの構成はこれに限らない。なお、装着部材７、弁部材８、ノズル部材１０及び回り止め部３ｂはそれぞれ、例えば合成樹脂によって形成される。 The dispenser body 3a has an assembly structure of an attachment member 7 having an attachment tube 7a and abutment portion 7b and capable of being screwed to the cap 3c via a second screw portion 6, a packing 9 that is axially sandwiched between the attachment member 7 and the mouth peripheral wall 2a when the dispenser body 3a is in the use position, a valve member 8 having a valve body 8a, and a nozzle member 10 having a discharge port 10a. However, the configuration of the dispenser body 3a is not limited to this. The attachment member 7, valve member 8, nozzle member 10, and anti-rotation portion 3b are each formed of, for example, synthetic resin.
　容器本体２は、例えば内容物を絞り出せるチューブ容器として構成され、内容物を吐出するための押圧操作を受けることで弾性変形可能であり、吐出具本体３ａは、容器本体２への押圧操作により内容物を吐出する吐出口１０ａを有する吐出キャップとして構成される。しかし、吐出容器１の構成はこれに限らない。例えば、吐出具本体３ａを操作に応じて内容物を吐出するポンプ装置として構成してもよい。 The container body 2 is configured, for example, as a tube container from which the contents can be squeezed out, and is elastically deformable when pressed to dispense the contents, and the dispenser body 3a is configured as a discharge cap having a discharge port 10a that dispenses the contents when pressed against the container body 2. However, the configuration of the discharge container 1 is not limited to this. For example, the dispenser body 3a may be configured as a pump device that dispenses the contents in response to operation.
　本発明は前述した実施形態に限定されず、その要旨を逸脱しない範囲で種々変更可能である。 The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the invention.
　したがって、前述した実施形態の吐出容器１は、口部周壁２ａと被係合部２ｂとを有する容器本体２と、吐出具本体３ａと回り止め部３ｂとを有する吐出具３とを有し、回り止め部３ｂは係合部４を有し、吐出具本体３ａは、口部周壁２ａに対して、容器本体２の内容物を吐出するための使用位置で螺合した状態から螺脱によって取り外し可能であり、回り止め部３ｂは、吐出具本体３ａが使用位置にある時に、係合部４が口部周壁２ａに対する吐出具本体３ａの螺脱方向の回転を規制するように被係合部２ｂに係合する係合位置と、係合部４が被係合部２ｂに係合しない非係合位置との間で、少なくとも係合位置から非係合位置に、口部周壁２ａの軸方向に操作に応じて移動可能である、吐出容器１である限り変更可能である。 Therefore, the dispensing container 1 of the above-mentioned embodiment has a container body 2 having a mouth peripheral wall 2a and an engaged portion 2b, and a dispensing tool 3 having a dispenser body 3a and a rotation preventing portion 3b, the rotation preventing portion 3b having an engagement portion 4, the dispenser body 3a can be removed by unscrewing it from a state where it is screwed into the mouth peripheral wall 2a in a use position for dispensing the contents of the container body 2, and the rotation preventing portion 3b can be moved at least from the engaged position to the non-engaged position in response to an operation in the axial direction of the mouth peripheral wall 2a between an engaged position where the engagement portion 4 engages with the engaged portion 2b so as to restrict rotation of the dispenser body 3a in the screwing direction relative to the mouth peripheral wall 2a, and a non-engaged position where the engagement portion 4 does not engage with the engaged portion 2b when the dispenser body 3a is in the use position, so long as it is a dispensing container 1.
