PROBLEM TO BE SOLVED: To provide a powder spouting vessel which can smoothly spout and easily meter the powder content. SOLUTION: This powder spouting vessel comprises a vessel body 12 which stores the powder to generate the bridge formation of particles and has an outlet 14 formed on one end, a closing unit 22 which is provided on the outlet 14 to close the outlet 14, and a middle plug 18 having a cylindrical spout 24 which is formed through the closing unit 22 and protruded outwardly. The vessel body 12 is flexible and formed of a squeezable synthetic resin, and a part from a side surface of the vessel body 12 to the outlet 14 is smoothly inclined. The diameter of the outlet 14 of the vessel body 12 is determined so that the powder is not clogged by the bridge, and the diameter of the spout 24 of the middle plug 18 is determined so that the powder can be stored by the bridge formation. By setting the vessel body 12 upside down and pressing a side surface of the vessel body 12, the powder bridged in the spout 24 can be spouted by the air pressure in the vessel body 12. |
