    • A device for emptying a film tube 15 containing a pasty substance comprises a cap structure 11 including a transverse wall 12 supporting the front of the tube, a cylindrical flange 13 formed on the wall for receiving the front end of the tube, and a dispensing pipe 17. The pipe 17 extends from a recess 16 formed in the wall 12 and having an at least partially circular-cylindrical shape, with a spike 18 being integrally formed at the center of the recess and extending parallel to the axis of the tube. The tip 19 of the spike is retracted from the plane of the wall 12. When dispensing pressure is exerted on the tube 15, the portion of the tube film overlying the recess 16 will bulge into the recess, until its central part is scratched by the tip 19 of the spike and thus caused to burst. The content of the tube can then flow into the recess 16 surrounding the spike 18 and out through the pipe 17.
    • 用于排空含有糊状物质的薄膜管15的装置包括盖结构11,其包括支撑管的前端的横壁12,形成在壁上用于容纳管的前端的圆柱形凸缘13和分配 管17从形成在壁12中的凹部16延伸并且具有至少部分圆柱形的形状,其中尖头18一体地形成在凹部的中心并且平行于管的轴线延伸。 尖头的尖端19从壁12的平面缩回。当分配压力施加在管15上时,覆盖凹部16的管膜的部分将凸出到凹部中,直到其中心部分被刮擦 尖端19的尖峰,从而导致爆裂。 然后,管的内容物可以流入围绕钉18的凹槽16中并通过管17流出。
