PROBLEM TO BE SOLVED: To provide a pressurizing device low in cost, recyclable and high in recovery ratio of contents by positioning a member composed of a cell material and product contents in a storage space so as to discharge the contents when a valve is operated and providing the member with at least one slit at its periphery. SOLUTION: The member 25 of a cylinder composed of the cell material is provided previously with an opening part 26 and the slit 28 before the member 25 is charged in a vessel main body 1. The outside diameter of the cylinder 5 charged in the vessel main body is made larger than that of the storage space 1.1 and compressive force in the horizontal direction is applied to enable to take out a small quantity of a product. A dipping tube 7 is inserted in a cylindrical center hole of the cylinder 5. When the product contents are forcibly charged, compressive force is applied to the cylinder 5 in the horizontal direction and the vertical direction, the inside diameter of an opening 16 is made slightly larger than the inside diameter of an opening 6 and the slit 8 is branched to form an opening 18. Then, the cylinder 15 freely moves along the dipping tube 17 corresponding to the relative density to the contents. |
