    • A drive screw having an axial bore is disposed within a tubular container. A cap for closing the container has mounted therefrom an applicator that is insertable in the bore of the drive screw. A first seal and a second seal, on the drive screw, form with the inner wall of the container and the outer wall of the drive screw an annular compartment for housing a cosmetic composition. A normally closed channel is provided between the compartment and the bore of the drive screw. A drive on the cap and a complementary drive on the drive screw cooperate with the first seal and the second seal to decrease the volume of the compartment in which the composition is housed each time the container is opened by removing the cap. A valve opens the channel in response to the decrease in volume in the compartment when the cap is removed so as to permit composition to flow through the channel into the bore of the drive screw to contact the applicator.
    • 具有轴向孔的驱动螺杆设置在管状容器内。 用于关闭容器的盖已经安装有可插入驱动螺杆的孔中的施加器。 驱动螺杆上的第一密封件和第二密封件与容器的内壁和驱动螺杆的外壁形成用于容纳化妆品组合物的环形隔室。 在隔室和驱动螺杆的孔之间设有常闭通道。 盖上的驱动器和驱动螺杆上的互补驱动器与第一密封件和第二密封件协作,以在每次通过拆卸盖子来打开容器时减小其中容纳组合物的隔室的体积。 当盖被移除时,阀响应于隔室中的体积减小而打开通道,以便允许组合物通过通道流入驱动螺杆的孔以接触施加器。
