PROBLEM TO BE SOLVED: To provide a liquid matter feeder capable of securely feeding a liquid matter, and in which the liquid matter is hard to be leaked from a liquid matter container even if being removed from equipment.SOLUTION: In a liquid matter feeder comprising: a miso container 6 as a liquid matter container and a positive displacement pump 7 fitted to the miso container 6 and discharging liquid miso as a liquid matter, the positive displacement pump 7 comprises: an outer tube 32 an inner tube 33 reciprocating so as to be freely retractable in an axial direction to the outer tube 32 a first check valve 41 checking the movement of the liquid miso from the outer tube 32 to the miso container 6 and a second check valve 51 checking the inflow of air from the outside to the inner tube 33, further, since the inner tube 33 is provided with a connection tube part 57 connected to a reciprocation mechanism 91 at the outside, the inner tube 33 of the positive displacement pump 7 is mechanically reciprocated by the reciprocation mechanism 91 at the outside, thus, even in the case liquid miso is fed for a plurality of times in relatively short time, the liquid miso can be securely be fed.COPYRIGHT: (C)2015,JPO&INPIT【課題】液状物を確実に供給できると共に、機器から外しても液状物容器から液状物が漏れにくい液状物供給装置を提供する。【解決手段】液状物容器たる味噌容器6と、この味噌容器6に取り付けられて液状物たる液状味噌を吐出させる容積型ポンプ7とを有する液状物供給装置において、前記容積型ポンプ7が、外筒32と、この外筒32に対し軸方向に出没自在に往復動する内筒33と、前記外筒32から味噌容器6への液状味噌の移動を阻止する第一逆止弁41と、外部から前記内筒33への空気の流入を阻止する第二逆止弁51を有すると共に、前記内筒33に、外部の往復機構91に接続される接続筒部57を設けたから、前記容積型ポンプ7の内筒33が外部の前記往復機構91によって機械的に往復動させられるので、比較的短時間で複数回液状味噌を供給する場合であっても、確実に液状味噌を供給することができる。【選択図】図2
