This invention is to provide an open instillation container which can always surely make a fixed quantity of liquid to drop down when its main body is pressed without detracting the advantage in manufacturing cost of its bottle pack type main body. At the front end section of the main body A of an container in which a liquid is simultaneously packed in a hermetically sealed state when the main body A is molded and which is made of a thermoplastic material, a bottomed conical recessed section 6b having an inside diameter which becomes larger as going toward the front end side is formed. In addition, a small-diameter liquid injection hole 6c is formed through the bottom of the recessed section 6b so as to control the quantity of a droplet squeezed out of the main body A to a set value.
