Description

上記課題を解決する液体収容ユニットは、液体噴射装置が備える液体噴射部に液体を供給する液体収容ユニットであって、前記液体を収容可能な液体収容部と、前記液体収容部を配するハウジングと、前記液体を前記液体収容部に注入するための注入口と、前記注入口を開閉するように構成された栓部材であって、前記注入口を覆う弾性変形可能な栓本体と、前記栓本体よりも高い剛性を有するとともに前記栓本体を保持する保持部材と、を含む、前記栓部材と、前記ハウジングおよび前記栓部材の一方に設けられた、前記栓部材を回動させるための軸部と、前記ハウジングおよび前記栓部材の他方に設けられた、前記軸部に係合する係合部と、前記係合部が前記軸部に係合された状態において前記係合部の軸方向の両側を挟むように前記軸部を支持する一対の支持部と、を備える。
この構成によれば、液体収容部へ液体を注入する液体注入作業を行うときなどユーザーが栓部材を開閉操作するときに、栓本体の液体がユーザーの指等に付着する頻度を低減できる。また、栓部材を軸部を中心に回動させることで注入口を開閉する構成なので、保持部材の軸部と反対側の端部を摘んで栓部材を開閉操作するときに、梃子の原理によって栓部材の開閉操作に要する力を小さくできる。 A liquid storage unit that solves the above-described problem is a liquid storage unit that supplies a liquid to a liquid ejection unit included in a liquid ejection device, the liquid storage unit capable of storing the liquid, and a housing that arranges the liquid storage unit An injection port for injecting the liquid into the liquid container; a plug member configured to open and close the injection port; and an elastically deformable plug body covering the injection port; and the plug body A holding member that holds the plug body, and a shaft portion that is provided on one of the housing and the plug member for rotating the plug member. An engagement portion that is provided on the other of the housing and the plug member and engages with the shaft portion; and both sides of the engagement portion in the axial direction in a state where the engagement portion is engaged with the shaft portion The axis to sandwich the shaft And a pair of support portions for supporting the.
According to this configuration, when the user opens and closes the plug member, for example, when performing a liquid injection operation for injecting liquid into the liquid storage unit, the frequency of the liquid in the plug body adhering to the user's finger or the like can be reduced. In addition, since the injection port is opened and closed by rotating the plug member around the shaft portion, when the plug member is opened and closed by grasping the end opposite to the shaft portion of the holding member, the principle of the lever is used. The force required for opening and closing the plug member can be reduced.

上記液体収容ユニットは、前記栓部材を上側から覆うカバーを更に備え、前記カバーまたは前記ハウジングは、前記保持部材が前記注入口を開ける方向へ回動した状態で接することにより前記保持部材の回動範囲を規制する規制部を有することが好ましい。 The liquid storage unit further includes a cover that covers the stopper member from above, and the cover or the housing rotates when the holding member is in contact with the holding member being rotated in a direction to open the inlet. It is preferable to have a restricting portion that restricts the range.

上記液体収容ユニットは、前記栓部材を上側から覆うカバーを更に備え、前記カバーは、前記栓部材を前記注入口に向かって押す押え部を含むことが好ましい。
この構成によれば、カバーを閉める際に押え部が栓部材を注入口に向かって押さえることにより、栓部材の浮きを抑制し、液体の蒸発・揮発を防止できる。 Preferably, the liquid storage unit further includes a cover that covers the plug member from above, and the cover includes a pressing portion that presses the plug member toward the inlet.
According to this configuration, when the cover is closed, the pressing portion presses the plug member toward the inlet, thereby suppressing the floating of the plug member and preventing evaporation and volatilization of the liquid.

この構成によれば、栓部材を閉じた後、カバーを閉じると、姿勢保持部が第１部材と第２部材とのうち少なくとも一方に接することにより保持部材が直状姿勢に保持される。このため、保持部材が屈曲姿勢をとる方向へ付勢されていても、カバーを閉じた状態において栓部材を閉位置に保持できる。よって、栓本体が付勢部材の付勢力によって注入口から外れる方向へ変位することに起因する封止ミスの発生頻度を低減できる。このため、例えば封止ミスに起因して液体収容部内への異物の混入や液体収容部から外部への液体の蒸発または揮発を抑制できる。
上記液体収容ユニットは、前記支持部または前記係合部のうち少なくとも一方から軸方向へ突出する軸ずれ防止部を更に備える。 According to this configuration, when the cover is closed after the stopper member is closed, the holding member is held in a straight posture by the posture holding unit contacting at least one of the first member and the second member. For this reason, even if the holding member is urged in the bending direction, the plug member can be held in the closed position with the cover closed. Therefore, it is possible to reduce the frequency of occurrence of sealing errors due to the stopper body being displaced in a direction away from the inlet by the biasing force of the biasing member. For this reason, for example, due to a sealing error, it is possible to suppress the entry of foreign matter into the liquid storage part and the evaporation or volatilization of the liquid from the liquid storage part to the outside.
The liquid storage unit further includes a shaft misalignment prevention portion protruding in the axial direction from at least one of the support portion and the engagement portion.
