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 deviceof the present invention comprises the outlet portionof a substantially bottomed tubular shape having the outlet orifice, the valve element support portionof substantially cylindrical shape that is secured in the outlet portionwith a distal endthereof exposed through the outlet orificeto the outside of the outlet portion, and a valve elementthat is secured in the outlet portionwith a distal endthereof exposed through the outlet orificeto the outside of the outlet portion. The distal endof the valve element makes contact with the valve element support portionso as to close the outlet orificewhen 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 portionwhen subjected to liquid pressure applied from the upstream U. The delivery containerof the present invention has the delivery deviceinstalled at the mouthof the squeeze bottle
