PROBLEM TO BE SOLVED: To deliver a constant volume of powder per one operation regardless of the magnitude of force required for pressurizing a container by turning round a container body from an upright position to its initial upright position to allow a predetermined volume of powder stored in a chamber to be delivered through a nozzle under pressure of the container body. SOLUTION: If a container body 1 storing a powder W therein is turned round from an upright position, the powder W flows into a chamber 6 from a through hole 01 formed near the outer periphery of a bottom wall 7b; however, the powder is prevented from flowing out directly through a nozzle 9 by being hindered by a central portion of the wall 7b. If the body 1 is returned to its original position, powder other than certain volume of powder having flowed into the chamber 6 is returned into the container body 1. Under such conditions, if the body 1 is pressurized from outside, air in the body 1 is forced into the chamber 6 through the hole 01 and flows against the underside 4a of a cover 4 so as to be delivered from the nozzle 9. As a result, a predetermined volume can be delivered per one operation and delivery of too much volume can be prevented. |
