PROBLEM TO BE SOLVED: To provide an extrusion container with a nozzle which extrudes the content to outside by pressing filling space by pushing a bottom wall, while releasing pressing to introduce outside air, and enabling extrusion of the content by pressing the bottom wall again.SOLUTION: The content pressed and transferred by pressing the bottom wall 3 is extruded through a gangway R of the nozzle 5, while outside air is introduced by releasing pressing, in an extrusion container with a nozzle. Inside of an opening edge of a circumferential wall 2, a partition wall having an opening Aprojecting toward the gangway, forwrding the content pressed and transferred from the filling space S, to the gangway side, and having an end 12 as a valve seat. An elastic valve 20 includes a cylindrical base section 21 inserted into the partition wall, and end side edge 23 of the cylindrical base section sits over all circumference of the valve seat, and closes the opening, to partition the filling space and the gangway, and makes the filling space lead to the gangway by opening the opening by separating from the valve seat by pressing and transferring the content, to form a discharge valve. |
