    • A spray dispenser comprises a container (12) in which a product-containing bellows (80) is situated above an energy storing bellows (82). A piston (70) is disposed within the container (12) below the energy storing bellows (82). A sleeve (40, 42) surrounds the container and is threadedly connected with the piston (70) where by rotation of the sleeve (40, 42) relative to the container (12) causes the piston (70) to rise and compress the energy storing bellows (82). The energy storing bellows (82) thus pressurizes the product-containing bellows (80) to expel the product when the valve (60) is opened. The outer diameter of the bellows (80) is of progressively reduced diameter to enable the bellows segments to become more snugly nested within one another when collapsing.
    • 喷雾分配​​器包括容器(12),其中含产品的波纹管(80)位于储能波纹管(82)的上方。 活塞(70)设置在能量储存波纹管(82)下面的容器(12)内。 套筒(40,42)围绕容器并且与活塞(70)螺纹连接,通过套筒(40,42)相对于容器(12)的旋转,活塞(70)升高并压缩能量 存放波纹管(82)。 因此,当阀(60)打开时,能量存储波纹管(82)对含产品的波纹管(80)加压以排出产品。 波纹管(80)的外径具有逐渐减小的直径,以使波纹管段在折叠时变得更贴近地彼此嵌套。
