ABSTRACT:
The present invention has an object to provide a delivery device that is capable of preventing a content liquid from flowing back and achieving aseptic delivery of liquid drop (dripping), and provide a delivery container, and an eye dropper that can eliminate or reduce the use of an antiseptic agent and achieve smooth delivery of the liquid. The delivery device10of the present invention comprises the outlet portion11of a substantially bottomed tubular shape having the outlet orifice12, the valve element support portion13of substantially cylindrical shape that is secured in the outlet portion11with a distal end13athereof exposed through the outlet orifice12to the outside of the outlet portion11, and a valve element14that is secured in the outlet portion11with a distal end14athereof exposed through the outlet orifice12to the outside of the outlet portion11. The distal end14aof the valve element makes contact with the valve element support portion13so as to close the outlet orifice12when there is no liquid pressure applied to the distal end portion from the upstream U, and deforms so as to form a flow passage between the distal end portion and the valve element support portion13when subjected to liquid pressure applied from the upstream U. The delivery container30of the present invention has the delivery device10installed at the mouth31aof the squeeze bottle31.
