    • A powder dispenser includes a resilient container for storing a powder and a volume of air therein. The powder has properties which enable a portion of the volume of air to fluidize a portion of the powder when the resilient container is sufficiently deformed. The dispenser has a substantially rigid conduit connected to its discharge end. The conduit provides the only fluid communication between the inside of the container and an ambient outside environment. The dispenser also has a resilient flat member connected to the outer end of the conduit. The flat member has a slit that is normally closed such that the container is substantially sealed in a fluid-tight manner until the container is sufficiently deformed to generate a pressure in the volume of air. When a pressure differential exists that is greater than a threshold value, the pressure differential causes the slit to open to discharge a portion of the powder mixed with a portion of the volume of air. The dispenser may also have an apertured member in the conduit that has at least one aperture therethrough having a total cross-sectional area smaller than a cross-sectional area of the conduit. The at least one aperture provides increased air velocity and turbulence to improve mixing of powder and air.
    • 粉末分配器包括用于在其中存储粉末和一定体积的空气的弹性容器。 当弹性容器充分变形时,粉末具有使一部分空气能够使粉末的一部分流体化的特性。 分配器具有连接到其排放端的基本上刚性的导管。 导管提供容器内部和环境外部环境之间唯一的流体连通。 分配器还具有连接到导管的外端的弹性平坦构件。 扁平构件具有通常关闭的狭缝,使得容器基本上以流体密封的方式密封,直到容器充分变形以产生空气体积中的压力。 当存在大于阈值的压力差时,压力差导致狭缝打开以排出与一部分体积空气混合的粉末的一部分。 分配器还可以在导管中具有有孔构件,其具有穿过其中的至少一个孔,其总横截面面积小于导管的横截面面积。 至少一个孔提供增加的空气速度和湍流以改善粉末和空气的混合。
