如图1至图14所示，本发明具有四个具体的实施例，现在详细描述。
实施例一：
如图1至图5所示，本实施例的一种真空容器，包括上端开口的容器本体1，所述的容器本体1内设有用于容纳盛装物的容纳腔100，所述容器本体1的上部设有密封座2，所述的密封座2上设有连通外界和容纳腔100的出物口201，所述的密封座2上设有用于将出物口201密封的密封件21，所述的密封件21能从密封座2上撕下，所述的容纳腔100内设有用于将容纳腔100内的盛装物从出物口201挤出的活塞3，所述活塞3密封且滑动地连接在容纳腔100内，所述活塞3的上端面和容纳腔100的上端面相吻合，使得当活塞3移动至上极限位置时，容纳腔100内的盛装物完全被挤出，所述的密封座2上设有用于驱动活塞3向上移动的驱动组件。本发明通过驱动组件来驱动活塞向上移动，进而将容纳腔内的盛装物从出物口挤出，外部的空气及杂质不会进入容纳腔内，便于提高盛装物的保质期；同时活塞的上端面和容纳腔的上端面相吻合，能将容纳腔内的盛装物完全挤出，避免浪费。
本实施例中，驱动组件包含设置在密封座2上的打气腔401，所述的打气腔401的下端连接有贯穿活塞3的导气管41，所述的活塞3与导气管41的外侧壁密封且滑动连接，所述的打气腔401上设有打气塞42，所述打气腔401内设有与打气塞42配合使用的密封片43，通过驱动打气塞42上下运动，能往活塞3的底部打气进而驱动活塞3上移。本实施例中通过向活塞的底部施加高压气体，进而驱动活塞上移。
