図３は、液体補充容器２０１によって液体を補充される液体吐出装置２００を示した斜視図である。図のように、本実施形態の液体吐出装置２００では、液体を供給する際には、容器カバー７を開き、液体補充容器２０１から液体収容容器１６が備える供給口１０６を介して貯留室１００の内部に液体を供給する。供給口１０６には供給口１０６に対して着脱自在の栓部材１０５が設けられており、液体補充容器２０１で補充を行う際には、供給口１０６の栓部材１０５を外して液体の供給を行う。なお、液体収容容器１６は、本実施形態のように液体吐出装置２００本体に組み込まれた構成に限定されず、液体収容容器１６から液体吐出ヘッド１５に液体を供給可能であれば、液体収容容器１６が液体吐出装置２００本体の外部に設けられた構成であってもよい。 FIG. 3 is a perspective view showing a liquid discharge device 200 in which a liquid is replenished by the liquid replenishment container 201. As shown in the figure, in the liquid discharge device 200 of the present embodiment, when the liquid is supplied, the container cover 7 is opened, and the storage chamber 100 is provided from the liquid replenishment container 201 through the supply port 106 provided in the liquid storage container 16. Supply liquid inside. The supply port 106 is provided with a plug member 105 that can be attached to and detached from the supply port 106, and when refilling with the liquid replenishment container 201, the plug member 105 of the supply port 106 is removed to supply the liquid. .. The liquid storage container 16 is not limited to the configuration incorporated in the main body of the liquid discharge device 200 as in the present embodiment, and is a liquid storage container as long as the liquid can be supplied from the liquid storage container 16 to the liquid discharge head 15. 16 may be configured to be provided outside the main body of the liquid discharge device 200.

図４は、本実施形態を適用可能な液体吐出装置２００の液体収容容器１６を示した斜視図である。本実施形態における液体収容容器１６は、ポリプロピレン等の合成樹脂で成形され、概ね直方体の外形を呈する。液体収容容器１６は、前壁１０１０と、右壁１０２０と、左壁１０３０と、上壁１０４０と、下壁１０５０とを有する。前壁１０１０は、下壁１０５０から概ね上下方向に延びる立壁１０１０Ａと、立壁１０１０Ａの上端に接続され且つ上下方向及び前後方向対して傾斜された傾斜壁１０１０Ｂ（外壁の一例）とで構成されている。傾斜壁１０１０Ｂは、立壁１０１０Ａに対して後方側に傾斜しており、この傾斜壁１０１０Ｂに供給口１０６が形成されている。 FIG. 4 is a perspective view showing a liquid storage container 16 of the liquid discharge device 200 to which the present embodiment can be applied. The liquid container 16 in the present embodiment is molded of a synthetic resin such as polypropylene and has a substantially rectangular parallelepiped outer shape. The liquid storage container 16 has a front wall 1010, a right wall 1020, a left wall 1030, an upper wall 1040, and a lower wall 1050. The front wall 1010 is composed of a vertical wall 1010A extending substantially in the vertical direction from the lower wall 1050, and a sloping wall 1010B (an example of an outer wall) connected to the upper end of the vertical wall 1010A and inclined in the vertical and front-back directions. .. The inclined wall 1010B is inclined to the rear side with respect to the vertical wall 1010A, and the supply port 106 is formed in the inclined wall 1010B.

一方、液体収容容器１６の後面は開放されている。そして、右壁１０２０、左壁１０３０、色間壁１０２１、１０２２、１０２３、上壁１０４０、下壁１０５０の後端部にフィルム１０６０が溶着されることによって、液体収容容器１６が封止され、後面である後壁が形成される。すなわちフィルム１０６０によって液体収容容器１６の後壁が形成される。こうして液室１１１０が形成される。 On the other hand, the rear surface of the liquid storage container 16 is open. Then, the film 1060 is welded to the rear ends of the right wall 1020, the left wall 1030, the intercolor wall 1021, 1022, 1023, the upper wall 1040, and the lower wall 1050, whereby the liquid storage container 16 is sealed and the rear surface thereof is sealed. The posterior wall is formed. That is, the film 1060 forms the rear wall of the liquid container 16. In this way, the liquid chamber 1110 is formed.

図５（ａ）、（ｂ）は、図４のＶ−Ｖにおける断面を示した図であり、本発明における栓部材１０５の一実施形態を示した図である。図５（ａ）は、栓部材１０５が供給口１０６に装着された様子を示しており、栓部材１０５は、液体漏れ防止のシール性を得るため、供給口１０６に圧嵌されるので、ゴムのような可撓性部材によって形成されるのが一般的である。栓部材１０５は、供給口１０６に装着された状態で貯留室１００や供給口１０６に対する外部に位置する本体部１０５Ｅと、供給口に挿入されて供給口を塞ぐ栓部１０５Ｃと、を備えている。栓部材１０５が供給口１０６を上下方向から挟み込むように弾性変形して供給口１０６に装着される。 5 (a) and 5 (b) are views showing a cross section in VV of FIG. 4, and are views showing one embodiment of the plug member 105 in the present invention. FIG. 5A shows a state in which the plug member 105 is attached to the supply port 106, and the plug member 105 is press-fitted to the supply port 106 in order to obtain a sealing property for preventing liquid leakage, so that rubber is used. It is generally formed by a flexible member such as. The plug member 105 includes a main body portion 105E that is attached to the supply port 106 and is located outside the storage chamber 100 and the supply port 106, and a plug portion 105C that is inserted into the supply port and closes the supply port. .. The plug member 105 is elastically deformed so as to sandwich the supply port 106 from above and below, and is attached to the supply port 106.

本実施形態における本体部１０５Ｅは、供給口１０６から取り外される時にユーザが栓部材１０５に力を加えることが可能な凸部１０５Ａと、液体収容容器本体と接続可能な支持部１０５Ｂと、供給口１０６の開口面を覆う覆部１０５Ｄと、を備えている。凸部１０５Ａは、栓部材１０５の覆部１０５Ｄの上面１０４から突出して設けられている。なお、上面１０４は、栓部材１０５が供給口１０６に取り付けられた状態で供給口１０６の開口面に沿っている。また、凸部１０５Ａの根元部と支持部１０５Ｂとは、栓部材１０５の中心部１０５ＣＰに対して一方側と他方側とに分かれて配置されている。つまり、凸部１０５Ａと、支持部１０５Ｂとは、栓部材１０５が供給口１０６に取り付けられた際に、供給口１０６の開口面と略垂直に交わる栓部材１０５の中心軸を含む面を挟んで一方側と他方側とに配置されている。 The main body 105E in the present embodiment has a convex portion 105A on which a user can apply a force to the plug member 105 when it is removed from the supply port 106, a support portion 105B that can be connected to the liquid storage container main body, and a supply port 106. It is provided with a covering portion 105D that covers the opening surface of the above. The convex portion 105A is provided so as to project from the upper surface 104 of the covering portion 105D of the plug member 105. The upper surface 104 is along the opening surface of the supply port 106 with the plug member 105 attached to the supply port 106. Further, the root portion and the support portion 105B of the convex portion 105A are separately arranged on one side and the other side with respect to the central portion 105CP of the plug member 105. That is, the convex portion 105A and the support portion 105B sandwich a surface including the central axis of the plug member 105 that intersects the opening surface of the supply port 106 substantially perpendicularly when the plug member 105 is attached to the supply port 106. It is arranged on one side and the other side.

より具体的に凸部１０５Ａと支持部１０５Ｂとの配置について図５（ｃ）を用いて説明する。図５（ｃ）は、栓部材１０５が供給口１０６に取り付けられた状態を、供給口１０６の開口面に直交する方向から見た上面図である。本実施形態では、覆部１０５Ｄはその上面１０４の形状が円形であり、栓部材１０５の中心部１０５ＣＰとは、図５（ｃ）に示すように覆部１０５Ｄの上面１０４の中心である。また、本実施形態では、上面１０４の形状が円形であり、上面１０４の中心と上面１０４の重心とが同じ位置にあるため、「中心（部）」と「重心（部）」とを言い換えて説明することもある。また、図５（ｃ）に示す中心部ＣＰを通る仮想直線Ｙは、中心部１０５ＣＰ（重心部）と支持部１０５Ｂとを結ぶ仮想直線Ｘに直交している。ここで、栓部材１０５が供給口１０６に取り付けられた状態で、仮想直線Ｙに対し、覆部１０５Ｄの一方側に凸部１０５Ａが配置され、覆部１０５Ｄの他方側に支持部１０５Ｂが配置される。 More specifically, the arrangement of the convex portion 105A and the support portion 105B will be described with reference to FIG. 5 (c). FIG. 5C is a top view of the state in which the plug member 105 is attached to the supply port 106 as viewed from a direction orthogonal to the opening surface of the supply port 106. In the present embodiment, the shape of the upper surface 104 of the covering portion 105D is circular, and the central portion 105CP of the plug member 105 is the center of the upper surface portion 104 of the covering portion 105D as shown in FIG. 5 (c). Further, in the present embodiment, since the shape of the upper surface 104 is circular and the center of the upper surface 104 and the center of gravity of the upper surface 104 are at the same position, the "center (part)" and the "center of gravity (part)" are paraphrased. It may be explained. Further, the virtual straight line Y passing through the central portion CP shown in FIG. 5C is orthogonal to the virtual straight line X connecting the central portion 105CP (center of gravity portion) and the support portion 105B. Here, with the plug member 105 attached to the supply port 106, the convex portion 105A is arranged on one side of the covering portion 105D and the supporting portion 105B is arranged on the other side of the covering portion 105D with respect to the virtual straight line Y. NS.

なお、本明細書でいう凸部１０５Ａが「突出する」とは、ユーザがつまんだり、力を加えたりすることができる程度に凸部１０５Ａが十分に突出している状態をいう。凸部１０５Ａと支持部１０５Ｂとがこのような配置で設けられていることで、ユーザが供給口１０６から栓部材１０５を取り外す際に、凸部１０５Ａをつまんで支持部１０５Ｂの方へ引き上げることが促される。このように、栓部材１０５の一方に設けられた凸部１０５Ａを支持部１０５Ｂの方へ引き上げることで、栓部材１０５は、凸部１０５Ａが設けられた側から徐々に変形して供給口１０６から外れることになり、比較的弱い力での取り外しが可能となる。また、一方側からの栓部材１０５の変形によって、圧嵌されている部分は、徐々に力が開放されて外れることから、栓部材１０５が供給口１０６から外れる際に一気に外れることがなく、液体収容容器１６内の液体が外部に飛散するのを抑制することができる。更に、栓部材１０５は、栓部材１０５を支持可能な支持部１０５Ｂを備えており、支持部１０５Ｂによって栓部材の覆部１０５Ｄが液体収容容器本体と接続されているため、脱落することが無い。なお、支持部１０５Ｂによって栓部材１０５が接続されるのは、液体収容容器本体に限定するものではなく、栓部材１０５が落下しなければ何に接続されていてもよい。 The term "protruding" as used in the present specification means that the convex portion 105A is sufficiently projected so that the user can pinch or apply a force. Since the convex portion 105A and the support portion 105B are provided in such an arrangement, when the user removes the plug member 105 from the supply port 106, the convex portion 105A can be pinched and pulled up toward the support portion 105B. Prompted. In this way, by pulling up the convex portion 105A provided on one side of the plug member 105 toward the support portion 105B, the plug member 105 is gradually deformed from the side where the convex portion 105A is provided and is provided from the supply port 106. It will come off and can be removed with a relatively weak force. Further, due to the deformation of the plug member 105 from one side, the pressure-fitted portion is gradually released from the force and is released, so that the plug member 105 does not come off at once when it comes off from the supply port 106, and the liquid It is possible to prevent the liquid in the storage container 16 from scattering to the outside. Further, the plug member 105 is provided with a support portion 105B capable of supporting the plug member 105, and the cover portion 105D of the plug member is connected to the liquid storage container main body by the support portion 105B, so that the plug member 105 does not fall off. The stopper member 105 is connected by the support portion 105B not only to the main body of the liquid storage container, but may be connected to anything as long as the stopper member 105 does not fall.

図５（ｂ）は、栓部材１０５を開ける際に、ユーザから力が加えられて変形した栓部材１０５を示した図である。ユーザが図中矢印方向に凸部１０５Ａを引っ張ると、栓部材１０５は、供給口１０６の支持部１０５Ｂが設けられている側の一部を支点にして、角度θを増やしつつ傾いて変形する。この時、栓部材１０５にかかる力の関係は、凸部１０５Ａの付け根を力点ＰＰ、供給口１０６の支持部１０５Ｂが設けられている側の一部を支点ＳＰ、支点ＳＰと反対側の供給口下部に位置する点を作用点ＷＰとするテコの原理となる。ここで、支点ＳＰから力点ＰＰまでの距離：Ｌ１とし、作用点ＷＰから支点ＳＰまでの距離：Ｌ２とする。距離Ｌ１を距離Ｌ２よりも長くとる（距離Ｌ１＞距離Ｌ２）ことで、力点ＰＰに加えた小さな力は作用点ＷＰにおいて大きな力となり、強い力を必要とすることなく供給口１０６から栓部材１０５を取り外すことができる。 FIG. 5B is a diagram showing a plug member 105 deformed by a force applied by a user when the plug member 105 is opened. When the user pulls the convex portion 105A in the direction of the arrow in the drawing, the plug member 105 is tilted and deformed while increasing the angle θ with a part of the supply port 106 on the side where the support portion 105B is provided as a fulcrum. At this time, the relationship of the force applied to the plug member 105 is such that the base of the convex portion 105A is the force point PP, a part of the side where the support portion 105B of the supply port 106 is provided is the fulcrum SP, and the supply port on the opposite side to the fulcrum SP. It is the principle of leverage that the point located at the bottom is the point of action WP. Here, the distance from the fulcrum SP to the force point PP is L1, and the distance from the action point WP to the fulcrum SP is L2. By making the distance L1 longer than the distance L2 (distance L1> distance L2), the small force applied to the force point PP becomes a large force at the point of action WP, and the plug member 105 from the supply port 106 does not require a strong force. Can be removed.

なお、図５（ｃ）に示すように、栓部材１０５が供給口１０６に取り付けられた状態で、凸部１０５Ａの一部が上述の仮想直線Ｘの延長線の上に配置されることが好ましい。このように配置することで、ユーザが供給口１０６から栓部材１０５を取り外す際に、凸部１０５Ａをつまんで支持部１０５Ｂの方へ引き上げることがより促されるためである。また、図５（ｃ）に示すように、凸部１０５Ａが仮想直線Ｙに対する一方側における覆部１０５Ｄの端部に配置され、支持部１０５Ｂが他方側における覆部１０５Ｄの端部に配置されていることが好ましい。このように配置することで、凸部１０５Ａと支持部１０５Ｂとの距離が長くなり、図５（ｂ）で説明したような距離Ｌ１を長くすることができるため、供給口１０６から栓部材１０５をより取り外し易くすることができるためである。なお、凸部１０５Ａと支持部１０５Ｂとの配置は図５（ｃ）に示すような配置に限定されるものではない。すなわち、凸部１０５Ａは仮想直線Ｙに対する覆部１０５Ｄの一方側の領域であればいずれの位置に配置されてもよく、また、支持部１０５Ｂは仮想直線Ｙに対する覆部１０５Ｄの他方側の領域であればいずれの位置に配置されていてもよい。 As shown in FIG. 5C, it is preferable that a part of the convex portion 105A is arranged on the extension line of the above-mentioned virtual straight line X in a state where the plug member 105 is attached to the supply port 106. .. This is because, when the user removes the plug member 105 from the supply port 106, the user is more encouraged to pinch the convex portion 105A and pull it up toward the support portion 105B. Further, as shown in FIG. 5C, the convex portion 105A is arranged at the end of the covering portion 105D on one side with respect to the virtual straight line Y, and the supporting portion 105B is arranged at the end of the covering portion 105D on the other side. It is preferable to have. By arranging in this way, the distance between the convex portion 105A and the support portion 105B becomes long, and the distance L1 as described with reference to FIG. 5B can be lengthened. This is because it can be made easier to remove. The arrangement of the convex portion 105A and the support portion 105B is not limited to the arrangement shown in FIG. 5C. That is, the convex portion 105A may be arranged at any position as long as it is in the region on one side of the covering portion 105D with respect to the virtual straight line Y, and the supporting portion 105B is located in the region on the other side of the covering portion 105D with respect to the virtual straight line Y. If there is, it may be arranged at any position.

なお、凸部１０５Ａの形状はこれに限るものでなく、例えば凸部の先端に球状や直方体の出張り形状を設けてもよい。先端に出張り形状を設けることで、ユーザが凸部をつまんだ際に指にかかりやすくなり、凸部に容易に力を加えることが可能となる。 The shape of the convex portion 105A is not limited to this, and for example, a spherical or rectangular parallelepiped protruding shape may be provided at the tip of the convex portion. By providing a protruding shape at the tip, when the user pinches the convex portion, it is easy for the user to touch the finger, and it is possible to easily apply a force to the convex portion.

また、支持部１０５Ｂは、栓部材１０５と一体に形成されていても、別体で形成されていてもよい。 Further, the support portion 105B may be formed integrally with the plug member 105 or may be formed separately.

また、覆部１０５Ｄの上面形状は上述したような円形に限るものでなく、例えば長方形などの対称形状や、非対称形状でもよい。これらの場合も、栓部材１０５の重心、すなわち、覆部１０５Ｄの上面１０４に一様に質量を分布させた際の質量中心を通る、上述の仮想直線Ｙに対し、一方側に凸部１０５Ａを配置し、他方側に支持部１０５Ｂを配置すればよい。 Further, the upper surface shape of the covering portion 105D is not limited to the circular shape as described above, and may be a symmetrical shape such as a rectangle or an asymmetrical shape. Also in these cases, the convex portion 105A is provided on one side with respect to the above-mentioned virtual straight line Y passing through the center of gravity of the plug member 105, that is, the center of mass when the mass is uniformly distributed on the upper surface 104 of the covering portion 105D. It may be arranged, and the support portion 105B may be arranged on the other side.

（変形例）
以下、本実施形態の変形例を説明する。
図６（ａ）から（ｃ）は、本実施形態の変形例の栓部材を示した図である。図６（ａ）の栓部材２０５は凸部２０５Ａを備えており、この凸部２０５Ａは栓部材１０５の覆部１０５Ｃの側面２０７から突出して設けられている。また、凸部２０５Ａの根元部と支持部１０５Ｂとは、栓部材１０５の中心部１０５ＣＰに対して一方側と他方側とに分かれて配置されている。また、図６（ｂ）の栓部材３０５は、凸部３０５Ａを備えており、凸部３０５Ａは、栓部材１０５の覆部１０５Ｃの側面３０７に複数の溝部を設けることで形成されている。凸部３０５Ａは、ユーザが栓部材３０５を外すにあたり側面３０７に指をかけた際に、側面３０７と指との摩擦力を高めるように作用する。なお、凸部３０５Ａと支持部１０５Ｂとは、栓部材１０５の中心部１０５ＣＰに対して一方側と他方側とに分かれて配置されている。また、図６（ｃ）の栓部材４０５は、凸部４０５Ａを備えており、凸部４０５Ａは、栓部材１０５の覆部１０５Ｃの側面４０７に切り欠き４０８を設けることで形成されている。この凸部４０５Ａは、ユーザが栓部材４０５を外すにあたり側面４０７に指をかけた際に、側面４０７と指との摩擦力を高めるように作用する。なお、凸部４０５Ａと支持部１０５Ｂとは、栓部材１０５の中心部１０５ＣＰに対して一方側と他方側とに分かれて配置されている。なお、それぞれの変形例における覆部１０５Ｃの側面は、栓部材１０５が供給口１０６に取り付けられた状態で、供給口１０６の開口面と略直交している。 (Modification example)
Hereinafter, a modified example of the present embodiment will be described.
6 (a) to 6 (c) are views showing a plug member of a modified example of this embodiment. The plug member 205 of FIG. 6A includes a convex portion 205A, and the convex portion 205A is provided so as to project from the side surface 207 of the covering portion 105C of the plug member 105. Further, the root portion and the support portion 105B of the convex portion 205A are separately arranged on one side and the other side with respect to the central portion 105CP of the plug member 105. Further, the plug member 305 of FIG. 6B is provided with a convex portion 305A, and the convex portion 305A is formed by providing a plurality of groove portions on the side surface 307 of the cover portion 105C of the plug member 105. The convex portion 305A acts to increase the frictional force between the side surface 307 and the finger when the user puts a finger on the side surface 307 when removing the plug member 305. The convex portion 305A and the support portion 105B are separately arranged on one side and the other side with respect to the central portion 105CP of the plug member 105. Further, the plug member 405 of FIG. 6C is provided with a convex portion 405A, and the convex portion 405A is formed by providing a notch 408 on the side surface 407 of the cover portion 105C of the plug member 105. The convex portion 405A acts to increase the frictional force between the side surface 407 and the finger when the user puts a finger on the side surface 407 when removing the plug member 405. The convex portion 405A and the support portion 105B are separately arranged on one side and the other side with respect to the central portion 105CP of the plug member 105. The side surface of the covering portion 105C in each modification is substantially orthogonal to the opening surface of the supply port 106 in a state where the plug member 105 is attached to the supply port 106.

なお、本実施形態では、栓部材は本体部と栓部とを備えている構成を説明したが、これに限定するものではなく、栓部を備えず本体部のみで構成されるいわゆるキャップ式の部材でもよい。 In the present embodiment, the configuration in which the plug member includes the main body portion and the plug portion has been described, but the present invention is not limited to this, and the so-called cap type is not limited to this and is composed of only the main body portion without the plug portion. It may be a member.

このように、供給口を閉じる栓部材において、凸部と支持部１０５Ｂとを、栓部材１０５の中心部１０５ＣＰに対して一方側と他方側とに分けて配置する。これによって、液体収容容器からの液体の漏れを防ぎ、液体を飛散させることなく開くことができる栓部材を備えた液体収容容器およびそれを備えた液体吐出装置を実現することができた。 In this way, in the plug member that closes the supply port, the convex portion and the support portion 105B are separately arranged on one side and the other side with respect to the central portion 105CP of the plug member 105. This made it possible to realize a liquid storage container provided with a plug member capable of preventing liquid leakage from the liquid storage container and opening without scattering the liquid, and a liquid discharge device provided with the plug member.

（第２の実施形態）
以下、図面を参照して本発明の第２の実施形態を説明する。なお、本実施形態の基本的な構成は第１の実施形態と同様であるため、以下では特徴的な構成についてのみ説明する。 (Second embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. Since the basic configuration of this embodiment is the same as that of the first embodiment, only the characteristic configuration will be described below.

図７（ａ）、（ｂ）は、本実施形態における栓部材５０５の一実施形態を示した図である。栓部材５０５は図７（ａ）のように、供給口１０６の内壁と当接して変形するように、栓部材５０５における圧嵌される部分の外周に突起部５０５Ｄを有し、栓部材５０５を供給口１０６に装着する際、その突起部５０５Ｄを変形させて供給口１０６を密閉する。なお、突起部５０５Ｄの断面形状は例えばＲ形状や三角形状がよい。 7 (a) and 7 (b) are views showing one embodiment of the plug member 505 in the present embodiment. As shown in FIG. 7A, the plug member 505 has a protrusion 505D on the outer periphery of the press-fitted portion of the plug member 505 so as to come into contact with the inner wall of the supply port 106 and deform. When attached to the supply port 106, the protrusion 505D is deformed to seal the supply port 106. The cross-sectional shape of the protrusion 505D may be, for example, an R shape or a triangular shape.

図７（ｂ）は、栓部材５０５を開ける際に、栓部材５０５にユーザから力が加えられた様子を示した図である。ユーザが図中矢印方向に凸部５０５Ａを引っ張ると、栓部材５０５は、支持部１０５Ｂが設けられている側の突起部５０５Ｄを支点にして、角度θを増やしつつ傾いて変形する。この時、栓部材５０５にかかる力の関係は、凸部根元を力点ＰＰ、支持部１０５Ｂが設けられている側の突起部５０５Ｄと供給口側面との当接部を支点ＳＰ、また支点ＳＰと反対側の供給口下部に位置する点を作用点ＷＰとするテコの原理となる。 FIG. 7B is a diagram showing a state in which a force is applied to the plug member 505 when the plug member 505 is opened. When the user pulls the convex portion 505A in the direction of the arrow in the drawing, the plug member 505 tilts and deforms while increasing the angle θ with the protrusion 505D on the side where the support portion 105B is provided as a fulcrum. At this time, the relationship of the force applied to the plug member 505 is such that the base of the convex portion is the force point PP, the contact portion between the protrusion 505D on the side where the support portion 105B is provided and the side surface of the supply port is the fulcrum SP, and the fulcrum SP. It is the principle of leverage that the point located at the lower part of the supply port on the opposite side is the point of action WP.

本実施形態の栓部材５０５によれば、供給口１０６内壁と突起部５０５Ｄとの圧嵌による突起部５０５Ｄの弾性変形で供給口１０６が密閉される。従って上記したテコの原理で容易かつ液体を飛散することなく栓部材を取り外すことができる。 According to the plug member 505 of the present embodiment, the supply port 106 is sealed by the elastic deformation of the protrusion 505D due to the pressure fitting between the inner wall of the supply port 106 and the protrusion 505D. Therefore, the plug member can be easily removed without scattering the liquid by the above-mentioned lever principle.

このように、栓部材５０５における圧嵌される部分の外周に突起部５０５Ｄを設け、突起部５０５Ｄを変形させて供給口１０６を密閉する構成とする。これによって、液体収容容器からの液体の漏れを防ぎ、液体を飛散させることなく開くことができる栓部材を備えた液体収容容器およびそれを備えた液体吐出装置を実現することができた。 In this way, the protrusion 505D is provided on the outer periphery of the press-fitted portion of the plug member 505, and the protrusion 505D is deformed to seal the supply port 106. This made it possible to realize a liquid storage container provided with a plug member capable of preventing liquid leakage from the liquid storage container and opening without scattering the liquid, and a liquid discharge device provided with the plug member.
