DEVICE FOR EMPTYING A FILM TUBE

摘要

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 end 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 centre 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.
